      Repetitive transcranial magnetic stimulation (rTMS) technology, which is amongst the most used non-invasive brain stimulation techniques currently available, has developed rapidly from 2009 to 2018. However, reports on the trends of rTMS using bibliometric analysis are rare. The goal of the present bibliometric analysis is to analyze and visualize the trends of rTMS, including general (publication patterns) and emerging trends (research frontiers), over the last 10 years by using the visual analytic tool CiteSpace V. Publications related to rTMS from 2009 to 2018 were retrieved from the Web of Science (WoS) database, including 2,986 peer-reviewed articles/reviews. Active authors, journals, institutions, and countries were identified by WoS and visualized by CiteSpace V, which could also detect burst changes to identify emerging trends. GraphPad Prism 8 was used to analyze the time trend of annual publication outputs. The USA ranked first in this field. Pascual-Leone A (author A), Fitzgerald PB (author B), George MS (author C), Lefaucheur JP (author D), and Fregni F (author E) made great contributions to this field of study. The most prolific institution to publish rTMS-related publications in the last decade was the University of Toronto. The journal Brain Stimulation published most papers. Lefaucheur et al.'s paper in 2014, and the keyword "sham controlled trial" showed the strongest citation bursts by the end of 2018, which indicates increased attention to the underlying work, thereby indicating the research frontiers. This study reveals the publication patterns and emerging trends of rTMS based on the records published from 2009 to 2018. The insights obtained have reference values for the future research and application of rTMS.

      BACKGROUND: One of the frequently used methods for assessing research trends and the impact of published scientific literature in a particular discipline is citation analysis. Journals may strive to improve their metrics by choosing manuscripts and study designs that are more likely to be cited. The aim of this study was to identify the 50 most-cited articles in the field of pediatrics, analyze their study design and other characteristics of those articles, and assess the prevalence of systematic reviews among them.METHODS: In December 2017, we searched Web of Science (WoS) for all articles published in the field of pediatrics. Two authors screened articles independently and in the further analysis included 50 articles with the highest number of citations. To avoid bias for scientific papers published earlier, the citation density was calculated. We also analyzed Journal Impact Factor (JIF) of journals where citation classics were published.
    RESULTS: The citation density in top 50 cited articles in the field of pediatrics ranged from 33.16 to 432.8, with the average of 119.95. Most of the articles reported clinical science. Median 2016 JIF for journals that published them was 6.226 (range: 2.778 to 72.406). Half of the top 10 highly cited articles in pediatrics were published in a journal with JIF below 5. Most of the studies among the citation classics in pediatrics were cross-sectional studies (N = 22), followed by non-systematic narrative reviews (N = 10), randomized controlled trials (N = 5), cohort studies (N = 5), systematic reviews (N = 2), case-control studies (N = 2), case reports (N = 2), and there was one study protocol and one expert opinion.
    CONCLUSION: Few randomized controlled trials and systematic reviews were among citation classics in the field of pediatrics. Articles that use observational research methodology, and are published in journals with lower impact factors, can become citation classics.

      BACKGROUND: There is not a holistic bibliometric study evaluating the publications in the literature even though trauma is a paramount subject in the field of critical care. This study aimed to investigate the important articles and journals receiving the most citations and publishing the most articles, revealing international cooperation and uncovering trend topics in this subject as a consequence of analyzing articles on trauma in the field of critical care published between 1980 and 2018 using bibliometric analysis methods.METHODS: Publication scan in this study was performed using Web of Science (WoS) database. Literature review was limited to only publications indexed in the field of Critical Care. "Trauma" was used as the keyword to reach relevant publications. Linear regression analysis was performed to predict the number of articles foreseen to be published in the upcoming years in the subject of trauma.
    RESULTS: As a result of the literature review, a total of 10851 publications were found. Six thousand four hundred and eighty-nine (59.8%) of these publications were under the category of article. First three countries with the most publications were respectively as the United States of America (4096) (63.1%), Canada (401) and Germany (380). Turkey ranked 21 with 41 publications. The article titled "Evaluating trauma care - the triss method" published in 1987 had received the most citations. The journal with the most publications and citations was "Journal of Trauma Injury Infection and Critical Care".
    CONCLUSION: This study will be a useful guide to all scientists and clinicians conducting research on trauma in critical care.

      Using a bibliometric method, this study assessed global educational research output on interprofessional education (IPE) and contributions from pharmacy relative to other healthcare academic programs, such as nursing, over the last 20 years. The Web of Science database was searched for articles published between 1998 and 2018. In addition, PubMed and the journals the American Journal of Pharmaceutical Education, Currents in Pharmacy Teaching and Learning, and INNOVATIONS in pharmacy were searched. Data were retrieved on January 31, 2019 and systematic content analysis method was used. Number of publications, citations, H-index, and scope of IPE research including IPE settings, IPE curriculum, pedagogy, and assessment methods was recorded. A total of 1693 references were retrieved that met the inclusion criteria. From the review of the literature, it was plausible to assume that the number of publications increased exponentially from 2010 to 2017. The results indicated that the top 5 healthcare disciplines contributing to the IPE literature included: medicine (41.2%), nursing (36.2%), pharmacy (9.0%), dentistry (8.2%), occupational therapy (5.6%), and physical therapy (4.6%). A total of 295 journals published IPE-related articles. The Journal of Interprofessional Care published a total of 566 articles, accounting for 33% of all published articles. In addition, a total of 66 countries contributed to IPE publications. The top 4 countries publishing in the area of IPE were the United States (27%), Canada (17.5%), the United Kingdom (16.1%), and Australia (10.2%). The content analysis of the articles identified diverse IPE settings, pedagogical methods, and assessments as major areas of IPE research.

      BACKGROUND Following total knee arthroplasty (TKA), postoperative patient rehabilitation is important to achieve the optimal level of knee function and mobility. Clinical research in this field is growing, and bibliometric analysis of publication may provide direction for research clinicians and raise awareness of research trends, journal selection, and key topics. Therefore, this bibliometric study aimed to analyze the current status and trends during the past two decades, between 1999 and 2018, of publications on rehabilitation after total knee arthroplasty (TKA) and used CiteSpace. MATERIAL AND METHODS The global literature was searched between 2018 to 2019 for publications related to rehabilitation after TKA. Publication data were identified using relevant search terms and the Web of Science Core Collection database. CiteSpace (5.3.R11) software was used to analyze the journals, authors, institutions, countries, cited references, and keywords using standard bibliometric indicators. RESULTS A total of 1,292 publications were retrieved between 1999 to 2018, and the most active journals, countries, authors, and institutions in the field of TKA rehabilitation were identified. Key areas of research included postoperative analgesia, muscle inhibition, range of motion, inhibitors, knee flexion, pain control, self-reporting, spectral analysis, in vivo forces, and rotator cuff repair. The emerging research topics included epidural analgesia, physiotherapy, postoperative analgesia, recovery, and the use of ropivacaine local analgesia. CONCLUSIONS The findings from this bibliometric study provided insight into trends in clinical research publications in the field of rehabilitation following TKA for the past 20 years, including global trends in emerging areas of research.

      Pre-exposure prophylaxis (PrEP) has been shown to be an effective approach to prevent human immunodeficiency virus (HIV) infections; however, implementation of the service remains challenging. This global bibliometric analysis aims to describe the current trends in HIV research prevention through PrEP to reveal the potential gaps of knowledge and to put forward recommendations for future research. A bibliometric analysis was conducted through Web of Science from 1990 to 2017. Exploratory factor analysis was also employed to find research domains emerging from the abstracts' contents. Latent Dirichlet allocation, which is a topic modeling algorithm, was utilized to perform text mining and determine relationships among text documents. A total of 4852 papers regarding HIV PrEP research were retrieved. The number of papers and their impact has significantly increased. Preventing sexual transmissions, improving access, and quality of health-care services for current users, as well as men who have sex with men, pregnant women and children, were the research domains most related to PrEP. We found a data gap in research regarding sex workers, potential side effects of PrEP, and misjudgment toward PrEP users. Despite the growth in research about HIV PrEP, there exist barriers to scaling up the implementation of PrEP worldwide and for such intervention to reach its fWull potential. International research collaboration efforts to investigate the potential safety concerns of PrEP and develop strategies to eliminate social misjudgment against PrEP users are warranted. Addressing these knowledge gaps might facilitate the development of effective global implementation strategies for PrEP in the future.

      Background: The mTOR pathway is vital for homeostasis, metabolism, cancer transplantation and regeneration in the liver. The aim of this study is to use a bibliometric method to reveal current research hotspots and promising future trends in mTOR signaling in liver diseases.Methods: Publications were searched and downloaded from the Web of Science Core Collection (WOSCC) Database. CiteSpace, Carrot2, and VOSviewer programs were utilized to analyze the contribution of various countries/regions, institutes, and authors; and to reveal research hotspots and promising future trends in this research area.
    Results: Until May 21, 2019, a total of 2,232 papers regarding mTOR signaling pathway in liver disease were included, and each paper was cited 23.21 times on average. The most active country was the USA. 5 landmark articles with centrality and burstiness were determined by co-citation analysis. Research hotspots included "liver transplantation" "hepatic stellate cell proliferation" "NAFLD" "therapy of HCC". Moreover, six key clusters were discovered during the procedure of "clustering", including "liver transplantation" "protein synthesis" "mTOR inhibitor" "following early cyclosporine withdrawal" "srebp-1 activation", and "hepatocellular cancer".
    Conclusions: Various scientific methods were applied to reveal scientific productivity, collaboration, and research hotspots in the mTOR signaling pathway in liver disease. Liver transplantation, hepatic stellate cell proliferation, non-alcoholic fatty liver disease (NAFLD), therapy of hepatocellular carcinoma (HCC), cell growth and autophagy, are research hotspots and are likely to be promising in the next few years. Further studies in this field are needed.

      The Royal Society of Chemistry is committed to investigating and addressing the barriers and biases which face women in the chemical sciences. The cornerstone of this is a thorough analysis of data regarding submissions, review and citations for Royal Society of Chemistry journals from January 2014 until July 2018, since the number and impact of publications and citations are an important factor when seeking research funding and for the progression of academic career. We have applied standard statistical techniques to multiple data sources to perform this analysis, and have investigated whether interactions between variables are significant in affecting various outcomes (author gender; reviewer gender; reviewer recommendations and submission outcome) in addition to considering variables individually. By considering several different data sources, we found that a baseline of approximately a third of chemistry researchers are female overall, although this differs considerably with Chemistry sub-discipline. Rather than one dominant bias effect, we observe complex interactions and a gradual trickle-down decrease in this female percentage through the publishing process and each of these female percentages is less than the last: authors of submissions; authors of RSC submissions which are not rejected without peer review; authors of accepted RSC publications; authors of cited articles. The success rate for female authors to progress through each of these publishing stages is lower than that for male authors. There is a decreasing female percentage when progressing through from first authors to corresponding authors to reviewers, reflecting the decreasing female percentage with seniority in Chemistry research observed in the "Diversity landscape of the chemical sciences" report. Highlights and actions from this analysis form the basis of an accompanying report to be released from the Royal Society of Chemistry.

      BACKGROUND: Surgical animal models are used in pre-clinical scientific studies. To date there has not been an analysis of how effective these data are when translated to human/clinical research. In this retrospective review, we evaluate the impact of studies using surgical animal models on human/clinical research through study-level analysis of citations.METHODS: The top two ranking clinical journals based on impact factor for the top ten surgical specialties were identified and a search was run on PubMed to identify studies using surgical animal models published in the years 2007 and 2008. The translation to human/clinical research of each study was evaluated by analyzing the frequency of citation in human studies over the ten years following publication. Regression was used to identify predictors of citation in human/clinical research.
    RESULTS: 411 animal studies using surgical models were identified. Over the course of the 10 years following publication the original animal studies were cited 6,063 times, with 1,300 (21.4%) citations in human/clinical studies and 4,763 (78.6%) in animal/basic science studies. The median number of citations in human/clinical research was 1 (IQR 0-5). Regression showed an association between citation in human/clinical research and the use of porcine models and the specialties of general surgery, oral and maxillofacial surgery, orthopedic surgery, transplant, and plastic surgery.
    CONCLUSION: The use of animal models in surgical research shows poor translation to human/clinical research. Alternative surgical models should urgently be explored.

      BACKGROUND: There is a global commitment to eliminating tuberculosis (TB). It is critical to detect and treat cases of latent TB infection (LTBI), the reservoir of new TB cases. Our study assesses trends in publication of LTBI-related research.METHODS: We used the keywords ("latent tuberculosis" OR "LTBI" OR "latent TB") to search the Web of Science for LTBI-related articles published 1995-2018, then classified the results into three research areas: laboratory sciences, clinical research, and public health. We calculated the proportions of LTBI-related articles in each area to three areas combined, the average rates of LTBI-related to all scientific and TB-related articles, and the average annual percent changes (AAPC) in rates for all countries and for the top 13 countries individually and combined publishing LTBI research.
    RESULTS: The proportion of LTBI-related articles increased over time in all research areas, with the highest AAPC in laboratory (38.2%/yr), followed by public health (22.9%/yr) and clinical (15.1%/yr). South Africa (rate ratio [RR] = 8.28, 95% CI 5.68 to 12.08) and India (RR = 2.53, 95% CI 1.74 to 3.69) had higher RRs of overall TB-related articles to all articles, but did not outperform the average of the top 13 countries in the RRs of LTBI-related articles to TB-related articles. Italy (RR = 1.95, 95% CI 1.45 to 2.63), Canada (RR = 1.73, 95% CI 1.28 to 2.34), and Spain (RR = 1.53, 95% CI 1.13 to 2.07) had higher RRs of LTBI-related articles to TB-related articles.
    CONCLUSIONS: High TB burden countries (TB incidence > 100 per 100,000 population) published more overall TB-related research, whereas low TB burden countries showed greater focus on LTBI. Given the potential benefits, high TB burden countries should consider increasing their emphasis on LTBI-related research.

      AIM: To describe the bibliometric characteristics of Tunisian publications on respiratory tract diseases, during the quinquennium 2010-2014.METHODS: This is a descriptive bibliometric study of respiratory medicine publications, indexed in "Medline", based on their MSDSs. All included articles were written by Tunisian researchers regardless of their position in the list of co-authors. The topics of the publications were explored through their "major" and "generic" keywords.
    RESULTS: A total of 340 publications was captured in Medline. These articles were co- authored by 218 authors in first position and 163 in last position. They were signed by pulmonologists, in first and last position respectively in 21.5% and 22.4% of articles. The A. Mami Hospital was the major affiliation of the first authors in 19.7% of the publications. These articles were published by 138 journals including "La Tunisie Medicale" in 11.8% of cases. They were "case reports" and written in English respectively in 44.4% and 54.1% of cases. Among 639 major keywords indexing, three were dominant: «Lung Neoplasms» (Tumeurs du poumon), «Chronic Obstructive Pulmonary Disease» (Broncho-pneumopathie chronique obstructive) and «Tuberculosis, Pulmonary» (Tuberculose pulmonaire), in 13.5%, 10.3% and 7.4% of articles respectively.
    CONCLUSION: Tunisian research on respiratory tract diseases has been thematically concordant with the public health needs. However, it has often been of low-level evidence and published in low-impact factor journals.

      OBJECTIVE:  A systematic search was performed for the identification and analysis of the 100 most often cited articles on dental caries and to highlight the changing trends in the field of dentistry over time.MATERIALS AND METHODS:  The search was performed without any restriction on the study design, publication year, or language using the Web of Science (WoS) group of Clarivate Analytics enabling the search through "All Databases." Based on the citation count as available in WoS, the articles were sorted in a descending manner. Information regarding each article was then extracted, which included its authorship, counts of citation (in other databases), citation density, current citation index (2019), publication year, country of publication, journal of article, evidence level based on study design, and keywords description.
    RESULTS:  The count of citation for each article varied in each database, that is, 175 to 2,003 in WoS, 89 to 1,981 in Scopus, and 126 to 3,492 when searched in Google Scholar. The highest number of articles (n = 10) related to dental caries were published in 2004. A total of 301 authors made valuable contributions to this field, out of which J.D. Featherstone had coauthored 6 articles. A significant negative correlation (p < 0.01) was found between the age of the article and the citation density (r =-0.545). However, a nonsignificant correlation (p = 0.952) occurred between the age of publication and the citation count (r = 0.006).
    CONCLUSION:  The results of this systematic review provide a critical appraisal of the context underpinning scientific developments in the field of dental caries and also highlighted trends in clinical management and research.

      The rising prevalence and global burden of diabetes fortify the need for more comprehensive and effective management to prevent, monitor, and treat diabetes and its complications. Applying artificial intelligence in complimenting the diagnosis, management, and prediction of the diabetes trajectory has been increasingly common over the years. This study aims to illustrate an inclusive landscape of application of artificial intelligence in diabetes through a bibliographic analysis and offers future direction for research. Bibliometrics analysis was combined with exploratory factor analysis and latent Dirichlet allocation to uncover emergent research domains and topics related to artificial intelligence and diabetes. Data were extracted from the Web of Science Core Collection database. The results showed a rising trend in the number of papers and citations concerning AI applications in diabetes, especially since 2010. The nucleus driving the research and development of AI in diabetes is centered around developed countries, mainly consisting of the United States, which contributed 44.1% of the publications. Our analyses uncovered the top five emerging research domains to be: (i) use of artificial intelligence in diagnosis of diabetes, (ii) risk assessment of diabetes and its complications, (iii) role of artificial intelligence in novel treatments and monitoring in diabetes, (iv) application of telehealth and wearable technology in the daily management of diabetes, and (v) robotic surgical outcomes with diabetes as a comorbid. Despite the benefits of artificial intelligence, challenges with system accuracy, validity, and confidentiality breach will need to be tackled before being widely applied for patients' benefits.

      BACKGROUND: The five BRICS (Brazil, Russian, Indian, China, and South Africa) countries bear 49% of the world's tuberculosis (TB) burden and they are committed to ending tuberculosis.OBJECTIVES: The aim of this paper is to map the scientific landscape related to TB research in BRICS countries.
    METHODS: Were combined bibliometrics and social network analysis techniques to map the scientific publications related to TB produced by the BRICS. Was made a descriptive statistical data covering the full period of analysis (1993-2016) and the research networks were made for 2007-2016 (8,366 records). The bubble charts were generated by VantagePoint and the networks by the Gephi 0.9.1 software (Gephi Consortium 2010) from co-occurrence matrices produced in VantagePoint. The Fruchterman-Reingold algorithm provided the networks' layout.
    FINDINGS: During the period 1993-2016, there were 38,315 peer-reviewed, among them, there were 11,018 (28.7%) articles related by one or more authors in a BRICS: India 38.7%; China 23.8%; South Africa 21.1%; Brazil 13.0%; and Russia 4.5% (The total was greater than 100% because our criterion was all papers with at least one author in a BRICS). Among the BRICS, there was greater interaction between India and South Africa and organisations in India and China had the highest productivity; however, South African organisations had more interaction with countries outside the BRICS. Publications by and about BRICS generally covered all research areas, especially those in India and China covered all research areas, although Brazil and South Africa prioritised infectious diseases, microbiology, and the respiratory system.
    MAIN CONCLUSIONS: An overview of BRICS scientific publications and interactions highlighted the necessity to develop a BRICS TB research plan to increase efforts and funding to ensure that basic science research successfully translates into products and policies to help end the TB epidemic.

      Objectives To evaluate research trends, including rates of misrepresentation of scholarly work, in otolaryngology residency applications received by a single institution during the 2018-2019 residency application cycle. Methods After obtaining Institutional Review Board approval, all residency applications to the Department of Otolaryngology-Head and Neck Surgery at Indiana University School of Medicine, Indianapolis, IN for the 2018-2019 cycle were de-identified and analyzed. Demographic and research information including the number of listed peer-reviewed articles/abstracts, types of research projects, and misrepresentations were retrospectively evaluated. Results Our institution received 321 applications, which represented 69.5% of the entire 2018-2019 otolaryngology applicant pool. The average United States Medical Licensing Examination (USMLE) Step 1 score was 246 ±12.4. There were 203 (62.2%) applicants who reported 591 published citations with 20 (6.2%) applicants misrepresenting 26 items (4.4%). Applicants who misrepresented research output had lower average Step 1 scores (237.4 vs 246.4, p: <0.05). Self-promotion to higher authorship status was the most common form of misrepresentation (61.5%). Conclusions The role of scholarly work in stratifying applicants continues to expand. Although a competitive application climate motivates a minority of applicants to misrepresent scholarly work, rates of misrepresentation in otolaryngology applications are low and continue to decline. The level of evidence assigned to this study is III.

      BACKGROUND: Bibliometric indexes are often used to evaluate and compare neurosurgeons and departments, and they were shown to correlate with academic rank and department reputation. We evaluated academic productivity of neurosurgeons practicing in departments accredited by the Joint Residency Advisory and Accreditation Committee (JRAAC) and European Association of Neurological Surgeons (EANS).METHODS: In this cross-sectional study we calculated number of publications, citations, h-index and m-quotient from the Pubmed/MEDLINE and Web of Knowledge databases for 285 neurosurgeons affiliated with 19 department that are accredited or in-progress of accreditation by the JRAAAC. Academic productivity was compared as a function of academic rank, research degree.
    RESULTS: Median number of publication in Pubmed/MEDLINE and Web of Knowledge indexed journals were 13 (range: 0-352) and 15 (range: 0-323), respectively. Median h-index was 4 (range: 0-41) and median m-quotient was 0.56 (range: 0-2.86). There was a significant variability between the studied departments in median number of publications and h-index (p=0.001). Professors and associate professors had significantly higher bibliometric indexes than neurosurgeon without academic rank (all p-values <0.001). Department chairmen had higher bibliometric indexes than other faculty members (all p-values <0.001). Neurosurgeons holding a research degree authored more publications and higher bibliometric indexes than faculty members not holding a research degree (p<0.001).
    CONCLUSIONS: This is the first study evaluating academic productivity of neurosurgeons practicing in Europe and Turkey. Higher academic rank and advanced research degree were associated with greater academic productivity. Further studies exploring regional differences in academic productivity of European neurosurgeons are encouraged.

      Enhancing the quality of life (QOL) of people living with HIV and AIDS (PLWHA) has become a significant global health goal, as combination antiretroviral therapy has helped to transform HIV/AIDS from a fatal illness to chronic disease. In this study, we aim to comprehensively describe the growth of research publications and the development of research landscapes regarding interventions to improve QOL among PLWH, as well as to characterize interdisciplinary topics and emerging interests of the research community. English articles and reviews published from 1991 to 2018 concerning interventions to improve QOL among PLWHA were retrieved from the Web of Science. Collaboration among organizations sharing coauthorships and co-occurrence network of authors' keywords was illustrated through network graphs. Latent Dirichlet Allocation was used for classifying papers into corresponding topics. A total of 2304 publications were included in the study. The USA continues to lead in research productivity, followed by South Africa, China, and India. Emerging research themes were found to be the application of multilevel interventions and long-term care, rehabilitation, along with topics relating to mental health issues, behavioral therapy and social supports for patients receiving treatments, and application of e-health approaches in designing and implementing interventions. There has been, however, a modest appearance of topics covering local, cultural, and environmental contexts of interventions. The findings of the study suggest expanding the coverage of psychosocial, behavioral, and contextualized interventions, increasing the involvement of family and community, improving the effectiveness of technology-based and e-health interventions, and developing strategies for lifelong treatment of HIV/AIDS.

      Academic scientists' engagement with industry is a central mechanism in university-industry knowledge transfer and the development of collaborative research. However, most empirical studies are limited to researchers in technical disciplines. We extend the analysis beyond engineers to include broader disciplinary fields, including humanists, economists, medicine, biosciences and cross-disciplinary scientists. Our findings suggest that cross-disciplinary researchers and researchers in technical sciences engage in more industry interaction than their peers. The motivations for the choice of research area play an important role in industry collaboration. Furthermore, we identify three types of industry interaction (interaction modes) among researchers: 1. educational interaction, consisting of conferences or seminars, corporate training programs, or supervising thesis work; 2. research interaction, consisting of shared publications, research-related consulting, public research programs and contract research; 3. integrated interaction, consisting of joint research in shared premisesand employment contracts with companies. Of these, the educational and research interaction modes (1 and 2) are motivated by the possibility of individual academic advancement. Integrated interaction (3) is rare and significantly correlates with only one of the three types of industry cooperation motivations: commercialization of research findings. We conclude by identifying future research needs, opportunities for methodological improvement and policy interventions.

      AIM: To describe the essential bibliometric characteristics of Tunisian publications in "infectiology", during the five-year period 2010-2014.METHODS: This is a descriptive bibliometric study, on the papers of "infectiology", indexed in "«Medline»", based on their data sheets. Were included all the articles written by Tunisian researchers regardless of their position in the list of co-signers. The themes of the publications were explored through the key words "major" and "generic" in the three chapters of the descriptors: "Bacterial Infections and Mycoses", "Parasitic Diseases", and "Viral Diseases".
    RESULTS: A total of 846 publications in "Infectiology" were analyzed, of which 66% were written in English and 31% were "case reports". They were signed by 536 authors in first position belonging mainly to microbiology (20.7%), parasitology (20.1%) and virology (7.1%). The 391 co-signatories in last position belonged to 44 specialties, of which pediatrics, internal medicine and infectious diseases respectively occupy the 4th, the 9th and the 10th positions. These publications were edited in 258 journals, mainly "Tunisie Medicale" (9%) and "Pan African Medical Journal" (3.8%). The greatest interest of the Tunisian researchers in infectious diseases have been staphylococcal / tuberculosis infections, chronic viral hepatitis C / human influenza, and echinococcosis / leishmaniasis.
    CONCLUSION: In Tunisia, infectious diseases research has been relatively prolific and concordant with the population's health needs. Infectious diseases physicians should build their network of care, research and education with biologists, while focusing their research on multicenter and high-level studies.

      This study reviewed articles originated in Brazil, in the United Kingdom, and in the United States from 1970 to September 2018 in the Web of Science database. Text mining techniques were used, and a predominantly qualitative analysis was performed, including correspondence analysis and sentiment analysis using the R Software (version 3.5.0) tools. Results show a repathologization of homosexuality in the gerontological knowledge production. This includes studies performed in 51 areas of knowledge in the three countries. That was followed by the depsychiatrization of homosexuality during the peak of deaths caused by AIDS, and its consequent recognition as an epidemiological threat. The article concludes reviewing the collected biomarkers, such as "sexual", "risk", "MSM", and "HIV/AIDS", which prove the progressive impact of sexual panic in gerontology studies and also associates AIDS with masculine homosexuality.

      The number of publications applying nonlinear mixed-effect (NLME) modeling has increased yearly since its first appearance in 1979. Here, we evaluated articles that have used NLME modeling, were published in journals that attract a broader audience, and we discussed the standard of presentation of these to stimulate target audience-specific improvements for increased impact in the future.

      The number of non-human animals used in research has increased in line with advances in medical technology, although it has previously been shown that these experiments demonstrate poor human utility. This study aimed to determine the effectiveness of animal studies on rats that were performed as part of medical doctors' residency master's theses prepared in Turkey between January 2006 and December 2015. The number of thesis-derived published papers from each year, as well as the subsequent citation rate of these papers, was determined. Results from 34% of the 656 analysed studies (226/656) were published as papers in PubMed-indexed journals. These 226 studies got 1803 subsequent citations in total. Citation counts were statistically significantly different in 2009 and 2010, as compared to 2011, 2013, 2014 and 2015. Previous studies showed that the usual main objective for carrying out animal studies in Turkey was the preparation of a thesis or the furthering of an academic career (i.e. personal self-interest). In the current study, the publication rate and the number of subsequent citations of these thesis-derived papers were both low, and thus, the contribution of these animal studies to scientific progress is doubtful. It is recommended that institutional research ethics committees should be much more highly selective in approving the use of animals for the purposes of student thesis preparation.

      BACKGROUND: Pediatric surgery remains the most competitive general surgery subspecialty. The authors suspected significant inflation in academic metrics since the last published paper. This study aimed to identify factors associated with applicant success in the match.METHODS: After IRB approval, all applications to a single accredited pediatric surgery fellowship program were reviewed for match years 2014-2018. Matched and unmatched applicants were compared in an unadjusted and adjusted analysis.
    RESULTS: This training program received 414 of 425 total applications (97%). Match results were available for 388 (94%). Matched applicants were more likely to train in programs with pediatric surgery fellowships (64% vs. 28%) and to have dedicated research time (55% vs. 21%; all p < 0.01). Matched applicants had more total publications (median: 12 vs. 7, p < 0.01) and higher ABSITE scores (median: 64th vs. 59th percentile, p < 0.01). Training in multiple programs negatively impacted the chance to match (p < 0.01). The median number of publications per applicant increased over the study time period from 7 to 11 (p < 0.01).
    CONCLUSIONS: The likelihood of matching into a pediatric surgery fellowship was related to the type of residency attended, dedicated research time, ABSITE scores, and number of publications. Overall, the total number of publications reported by all applicants increased.

      The professional journals of stomatology, which were dedicated to spread of theoretical knowledge and medical practices, has demonstrated their important value for studying the development of stomatology. The historical details of these stomatological journals published in modern China from 1840 to 1949, such as publication background, chief founders, aims, main features and the contents of articles, are of great importance for investigating not only the humanistic features, but also the development of stomatology in China. Twenty-three professional journals of stomatology in modern China and 2 260 articles published in them have been verified through text analysis and archives. The features and functions of these journals were further analyzed in order to enrich the humanities and historical research of modern Chinese stomatology.
