      Medical information on English Wikipedia was accessed over 2 billion times in 2018. Our goal was to develop an automated system to assist Wikipedia volunteers to improve articles with high-quality sources from journals such as The Cochrane Library. We created an automated indexing system by linking available reviews from the Cochrane library with disease-related Wikipedia articles and evaluating the relationship between the quality and importance of these articles with the number of relevant and cited Cochrane reviews. We first conducted a bibliometric analysis, identifying disease-related Wikipedia articles and relevant/cited Cochrane reviews. Citations were thematically coded, and descriptive statistics were calculated. Finally, separate multinomial logistic regression analyses were conducted for article quality and importance. The indexing system identified 4381 disease-related Wikipedia articles, 1193 (27%) of which cited a Cochrane review. Higher quality Wikipedia articles were more likely to cite a Cochrane review (p = 0.002), while lower quality articles were less likely to cite a Cochrane review (p < 0.0005). A greater number of Cochrane reviews are available for more 'important' Wikipedia articles (p < 0.005), and these articles were more likely to cite a Cochrane review (p < 0.005). This approach to an indexing system can be leveraged by Wikipedia contributors and editors seeking to update disease-related Wikipedia articles with relevant Cochrane reviews (thus improving their quality), and online information seekers in need of additional information to supplement their Wikipedia search.

      Background: The aim of the current study is to determine the Comparison of intellectual structure of International Journal of Preventive Medicine (IJPM) with Medical Subject Headings (MeSH) based on author keywords and index terms of Scopus database and the degree of compatibility among these two groups of keywords.Methods: This study was carried out using a co-word technique, which is one of the bibliometric methods. The study population consisted of 1104 articles published in IJPM and indexed in Scopus database. After retrieval the articles, data for co-word analyses was extracted using UCINET and VOSviewer software applications and centrality criteria. Then, the compatibility of author keywords and MeSH terms was examined by Jaccard's similarity index.
    Results: During the investigated years and among 2402 author keywords, on average, 561 author keywords (23.36%) were exact matches, 417 author keywords (17.36%) were partial matches, and 1424 author keywords (59.28%) were not matched with the terms contained in the index. Author keywords matching or not matching with index-term categories formed the largest portion of partial match keywords.
    Conclusions: The use of MeSH as a standard tool by medical journals for the selection of keywords in scientific publications could improve the visibility and retrieval of articles, and increase the number of citations and journals' impact factor.

      Purpose: The purpose of this study was to examine whether disparities in promotion and academic productivity exist within academic pediatric dentistry. Methods: The top 15 schools funded by the National Institute of Dental and Craniofacial Research were included in this study. Gender differences in productivity and advancement were evaluated. Results: Women comprised 48.9 percent of all faculty surveyed (n=184). Less than a third of full professors were women. Female faculty graduated more recently (18.2 years; [95 percent confidence interval (95% CI) equals 15.4 to 20.9], versus 28.5 years for men [95% CI equals 24.8 to 32.1]; P<0.001) and had fewer senior author publications (1.6 [95% CI equals 1.9 to 5.1] versus 3.5 [95% CI equals 0.7 to 2.4]; P=0.03) than their male colleagues. In a linear regression correcting for number of publications and years since graduation, gender was not a significant predictor of academic advancement. Conclusions: Most women in academic pediatric dentistry remain in lower academic tiers with fewer senior author publications. This discrepancy is explained by the years since graduation between male and female faculty at lower levels of academic advancement. Increasing scholarship opportunities and compensation for female faculty members may help improve gender equity in dental academia.

      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.

      PURPOSE: Gender differences in faculty advancement persist in academic medicine. Understanding of what drives these differences remains limited. The relationship among self-esteem, gender, and career outcomes has not previously been explored.METHOD: The authors evaluated the association between gender and 2012-2013 career outcomes, specifically, the number of publications, academic rank, leadership positions, and retention, and whether self-esteem as measured in the 1995 National Faculty Survey mediates this relationship. They measured self-esteem using the modified Rosenberg Self-Esteem Scale. The authors used multivariable logistic regression analysis to understand the association among gender, self-esteem, and the outcomes of rank, leadership, and retention, and negative binomial models for number of publications. Models were adjusted for race, specialty, effort distribution, and years since first faculty appointment. The authors performed a mediation analysis to understand whether self-esteem mediates the relationship between gender and these career outcomes.
    RESULTS: Overall, self-esteem scores were high. Women had lower self-esteem in 1995 than their male colleagues. In adjusted models, female gender was associated with lower performance on all four career outcome metrics. While self-esteem scores were positively associated with all four outcomes, the authors' mediation analysis suggested that self-esteem did not mediate the relationship between gender and these 4 career metrics.
    CONCLUSIONS: Female medical faculty members lag behind men on traditional metrics of faculty achievement. While higher self-esteem is positively associated with faculty achievement, it did not mediate the relationship between gender and career advancement over the 17 years of follow-up and, thus, may not be an ideal target for programs and policies to increase gender parity in academic medicine.

      Background: Altmetrics analyze the visibility of articles in social media and estimate their impact on the general population. We performed an altmetric analysis of articles on central nervous system inflammatory demyelinating disease (CIDD) and investigated its correlation with citation analysis.Methods: Articles in the 91 journals comprising the "clinical neurology," "neuroscience," and "medicine, general, and internal" Web of Science categories were searched for their relevance to the CIDD topic. The Altmetric Explorer database was used to determine the Attention Score (AAS) values of the selected articles. The papers with the top 100 AAS values were characterized.
    Results: Articles most frequently mentioned online were primarily published after 2014 and were published in journals with high impact factors. All articles except one were dealt with the issue of multiple sclerosis. Most were original articles, but editorials were also common. Novel treatments and risk factors are the most frequent topics. The AAS was weakly correlated with journal impact factors; however, no link was found between the AAS and the number of citations.
    Conclusions: We present the top 100 most frequently mentioned CIDD articles in online media using an altmetric approach. Altmetrics can rapidly offer alternative information on the impact of research based on a broader audience and can complement traditional metrics.

      OBJECTIVE: To evaluate the publication rate of abstracts presented at the Canadian Ophthalmological Society (COS) Annual Meetings from 2010 to 2015.DESIGN: A retrospective review and literature search of abstracts presented at the COS Annual Meetings from 2010 to 2015.
    METHODS: Abstracts were obtained from the scientific programs for the 2010-2015 COS meetings, excluding 2014 (data unavailable). Title, author number, presentation type, subspecialty, institution, and study design were collected. MEDLINE and PubMed were searched in duplicate using abstract title, key words, and authors. Publication date, journal, impact factor, and citation score were recorded for each publication. Publication rates were determined by year of abstract presentation, presentation type, study type, subspecialty, author number, institution, and time to publication.
    RESULTS: 876 abstracts were presented, of which 326 (37.3%) were posters and 548 (62.7%) were oral presentations. The publication rate was 42.9% (375 publications) with a 16-month median time to publication. The publication rate did not vary significantly by presentation type or year. Publication rates were highest among vision rehabilitation (75.0%) and glaucoma (52.0%) subspecialties; basic science research (65.0%) and systematic reviews/meta analyses (62.0%) study designs had the highest representation. Most presentations were published in the Canadian Journal of Ophthalmology (117 presentations, 31.2%). The mean impact factor and citation score for published abstracts were 2.39 ± 2.3 and 1.70 ± 1.16, respectively.
    CONCLUSIONS: The publication rate of abstracts presented at the COS Annual Meetings has remained stable across this 5-year analysis. Publication rates are comparable to those of other specialty conferences.

      Introduction: Peer-reviewed research helps to advance many aspects of medical and surgical practice. This paper determines the main contributors tos joint arthroplasty research in terms of quantity and quality.Methods: A search of the Web of Science™ platform was conducted to identify arthroplasty articles published between 2001 and 2016. The number of articles and citations per article were analysed to assess the quantity and quality of research from individual countries. Results were standardised according to the country's populations and Gross Domestic Product (GDP).
    Results: In total, 43,470 arthroplasty articles were published worldwide from January 2001 through December 2016. There was a 4.5-fold increase in global output during this time period. Twenty-two countries contributed at least 1% to the total number of publications. The United States of America published the most articles (35.40%), followed by England (10.31%) and Germany (10.03%). The USA had the highest absolute number of citations (50,777). Denmark had the highest average citation per item (8.76). When number of articles was normalized to population, Switzerland ranked the highest. When adjusted by GDP, Scotland ranked highest. When standardised according to GDP per capita, the People's Republic of China rated highest. The Journal of Arthroplasty produced the highest number of publications related to arthroplasty with 10.9% of total volume.
    Conclusion: There has been a substantial increase in worldwide publications relating to arthroplasty. The USA has produced the largest volume whilst Denmark has produced the highest quality publications. When output was normalized according to population and GDP, Switzerland and Scotland ranked highest.

      The attendant threats of climate change in the Arab world are accelerating at a high pace. The realization of these risks has promoted scientific research activities in climate change (i.e., modeling of climate change effects and development of mitigation and adaptation measures). A bibliometric analysis was desired to trace the status and trends of these research activities with an origin from the Arab world. The aim was to contribute to a better understanding of the scientific knowledge of climate change and its impacts and survey its evolution. Moreover, it is aimed at enabling recommendations for future research activities in this field. The data of this analysis were retrieved from the Scopus database using the most common terms of climate change to search titles, abstracts, and keywords. The collected data, in the form of documents referring to climate change, enabled to extract and further assess different quantitative and qualitative bibliometric indicators. Productivity of countries, sources, and institutions; collaboration figures; impact of published research; and citation rates were being among the assessed indicators. Subsequently, the data were analyzed using visualization maps and clustering techniques to characterize the hot spots and vital topics of research. A total of 2074 documents (1.2% of the total global research output) were retrieved from the Arab world. Saudi Arabia took the leading positions in terms of the number of publications (473 documents; 22.8%), impact of research (Hirsch index (h-index), 48), collected citations (10,573 citations), and number of documents from collaboration (389 documents). The USA was the most collaborated country with the Arab world (344 documents; 17.0%), followed by France (311 documents; 15.0%). The most productive journal was Plos One (42 documents; 2.0%), followed by the Arabian Journal of Geosciences (38 documents; 1.8%). Three institutions from Saudi Arabia were in the forefront in terms of research productivity (King Abdulaziz University, 124 documents; King Saud University, 117 documents; and King Abdullah University of Science and Technology, 102 documents). The vital climate change-related topics which will continue to be active in the future are climate modeling, physiology, genetics, and animals. The present data indicate a committed scientific research progress. Increasing the fund, capacity building, and development of regional experience with climate change-related disasters are key factors to promote the scientific research in this field.

      BACKGROUND: This article describes the research trends in sperm DNA fragmentation (SDF) over the past 20 years (1999-2018) using a scientometric approach.METHODS: A stepwise approach was adopted to retrieve scientometric data (articles per year, authors, affiliations, journals, countries) from Scopus and analyze the publication pattern of SDF with reference to key areas of research in the field of Andrology.
    RESULTS: A total of 2121 articles were retrieved related to SDF. Our data revealed an increasing research trend in SDF (n = 33 to n = 173) over the past 20 years (R2 = 0.894). Most productive country in publications was the USA (n = 450), while Agarwal A. (n = 129) being the most productive author. Most of the articles in SDF were primarily focused on lifestyle (n = 157), asthenozoospermia (n = 135) and varicocele (130). Mechanistic studies on SDF were published twice as much as prognostic/diagnostic studies, with significant emphasis on oxidative stress. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) was the most widely used technique to evaluate SDF. Publications on SDF related to assisted reproductive techniques also showed a linear increasing trend (R2 = 0.933).
    CONCLUSIONS: Our analysis revealed an increasing trend in SDF publications predominantly investigating lifestyle, asthenozoospermia and varicocele conditions with TUNEL being the most widely used technique. A substantial increase in research is warranted to establish SDF as prognostic/diagnostic parameter to evaluate clinical scenarios and ART outcomes.

      Background: Despite increased attention on science and research in the United Arab Emirates (UAE), little is known about the national state of research productivity and how it evolved over time.Methods: Using the world's largest bibliometric database (Scopus), we reviewed research productivity in the UAE (1998-2017) in various disciplines and normalized it to population size and gross domestic product. We summarized the quality of research using conventional metrics of research quality and compared the performance of the UAE to its geographic region and to other countries of similar population size and economic standing.
    Results: Over the past 20 years, there was a 16-fold increase in the number of research publications from the UAE, and a 6- and 3-fold increase when normalized to population size and gross domestic product, respectively. Growth was observed across all disciplines, with an increasingly diverse research portfolio, and was coupled with a slight increase in the quality of publications. The crude productivity in the UAE was higher than that observed for the gulf cooperation council or Arab region, but lower when normalized to gross domestic product, or when compared to two countries outside the Arab region with remarkable research growth.
    Conclusions: Over the past 20 years, the UAE witnessed a significant increase in research productivity, coupled with a slight increase in quality and diversity of research. Accounting for the UAE's economic standing, and compared to other countries with excellent research output, the UAE has significant potential for further growth with increased resources for research and development.

      PURPOSE: This study aimed to identify the 100 most cited research articles on cervical cancer brachytherapy.METHODS AND MATERIALS: The Institute for Scientific Information Web of Science was used to identify the 100 most cited articles in cervical cancer brachytherapy as of July 5, 2019. The following important information was extracted: journal, year and month, country of region, author, type of article, type of dose rate, type of radionuclide, and image modality for brachytherapy planning.
    RESULTS: The 100 most cited articles in cervical cancer brachytherapy were published between 1981 and 2016, and the citations ranged from 858 to 49, which collectively had been cited 11,372 times at the time of searching. The index of citations per year ranged from 63.56 to 1.43. These articles were from 16 countries or regions, with most publications being from the United States (n = 27), followed by Austria (n = 26), Japan (n = 10), France (n = 7), and the Netherlands (n = 7). The International Journal of Radiation Oncology, Biology, Physics produced the most articles (n = 46), followed by Radiotherapy and Oncology (n = 39) and Gynecologic Oncology (n = 5). These articles were categorized as original studies (n = 75), reviews (n = 2), editorials (n = 2), surveys (n = 2), guidelines (n = 3), and recommendations (n = 6). A high dose rate (n = 69) was the most widely used, dose rate followed by a low dose rate (n = 20) and pulsed dose rate (n = 16).
    CONCLUSIONS: The bibliometric analysis presents a detailed list of the 100 most cited articles in cervical cancer brachytherapy. This analysis provides an insight into historical developments and enables the important advances in this field to be recognized.

      Many clinical studies on Cheezheng Xiaotong Tiegao have been accumulated since it was launched in 1993,but they have not been comprehensively analyzed and evaluated. This study systematically retrieved relevant studies in six databases at home and abroad as of December 2017. This study analyzed the statistics of the included studies in several aspects,including publication time,region,fund,disease category and type of study. In this study,various tools were used to evaluate the methodological quality of included studies,such as the Cochrane collaboration's tool for assessing the risk of bias in randomized trials,MINORS,IHE,AMSTAR2.The results showed that the literatures were mainly published from 2010 to 2011,and a total of 28 projects were financially supported.The most involved disease was arthropathy. The randomized controlled trials were the majority in the included studies,but the quality was low,and most of the literatures didn't report the allocation concealment and blinding. This study comprehensively reflected the current situations and shortcomings of the clinical studies of Cheezheng Xiaotong Tiegao,and put forward several suggestions,in the expectation of providing a reference for the future clinical research direction of Cheezheng Xiaotong Tiegao.

      Background: Water is a scarce resource and is considered a fundamental pillar of sustainable development. The modern development of society requires more and more drinking water. For this cleaner wastewater, treatments are key factors. Among those that exist, advanced oxidation processes are being researched as one of the sustainable solutions. The main objective of this manuscript is to show the scientific advances in this field. Methods: In this paper, a systematic analysis of all the existing scientific works was carried out to verify the evolution of this line of research. Results: It was observed that the three main countries researching this field are China, Spain, and the USA. Regarding the scientific collaboration between countries, three clusters were detected-one of Spain, one of China and the USA, and one of Italy and France. The publications are grouped around three types of water: industrial, urban, and drinking. Regarding the research, 15 clusters identified from the keywords analyzed the advanced oxidation process (alone or combined with biological oxidation) with the type of wastewater and the target pollutant, removal of which is intended. Finally, the most important scientific communities or clusters detected in terms of the number of published articles were those related to the elimination of pollutants of biological origin, such as bacteria, and of industrial nature, such as pesticides or pharmaceutical products.

      OBJECTIVE: To describe the bibliometric characteristics of Tunisian publications in "General Surgery", indexed in "Medline" database from 2009 to 2018.METHODS: This is a bibliometric study conducted through a comprehensive documentary query applied to the "Pubmed" portal and using the "Medline" database. The essential themes of a publication have been defined by referring to its major keywords.
    RESULTS: A total of 173 publications were included in this study, representing a productivity rate of 14 articles / 100 surgeons' teachers-year. These publications were co-authored by 65 authors in first position and published by 55 journals in 15 countries, including mainly the national journal "Tunis Med" during the first five-year period 2009-2013 (27%) and the Ugandan magazine "Pan Afr Med J" during the second five-year period 2014-2018 (33%). Case reports were the most widespread type of publication in Tunisian "General Surgery", during the two periods of the study, respectively in 63% and 51% of cases. English was the major language with 57% of publications. Among the 259 major descriptors used to index the "General Surgery" articles, the occurrence of "Pancreatic Neoplasms" and "Echinococcosis, Hepatic" was respectively 3% and 2%.
    CONCLUSION: During the decade 2009-2018, the Tunisian research in "General Surgery" was not very prolific and was mainly "case reports" but it was directed toward population health problems; Hence the interest of a thorough training of surgeons in research methodology and scientific medical writing.
