      Institutions of higher learning are critical in promoting a knowledge-driven economy through research and training. Nepali universities receive funding from the University Grants Commission, Nepal (UGC-N) to support for impactful research. UGC-N requires grantees to publish research results as journal articles. We reviewed papers published through UGC-N funded research projects over a 10-year period (2008-2018) to assess the trends of article publication in terms of frequency and quality (based on journal impact factor and SCImago journal ranking). At most, 17% projects (n=325) had publications and the majority of articles were published in journals that had neither SJR rank (74 %, n=240) nor impact factor (86%, n=279). Most importantly, 10% of articles (n=23) published in the non-ranked journals appeared in predatory journals. Although there were increasing trends of grants and research article publications in the last 10 years, journal level quality metrics showed no improvements and suggested decreasing trends during the last half decade. The publication output varied among grant categories. Master research grants and PhD research grants performed better than those of faculty research grants in terms of publication in quality journals. We call for an increased commitment from political and academic leadership to promote quality research in Nepal.

      Introduction Although bibliometric analyses have been performed in the past on cancer and genomics, little is known about the most frequently cited articles specifically related to cancer epigenetics. Therefore, the purpose of this study is to use citation count to identify those papers in the scientific literature that have made key contributions in the field of cancer epigenetics and identify key driving forces behind future investigations. Materials and methods The Thomas Reuters Web of Science services was queried for the years 1980-2018 without language restrictions. Articles were sorted in descending order of the number of times they were cited in the Web of Science database by other studies, and all titles and abstracts were screened to identify the research areas of the top 100 articles. The number of citations per year was calculated. Results We identified the 100 most-cited articles on cancer epigenetics, which collectively had been cited 147,083 times at the time of this writing. The top-cited article was cited 7,124 times, with an average of 375 citations per year since publication. In the period 1980-2018, the most prolific years were the years 2006 and 2010, producing nine articles, respectively. Twenty-eight unique journals contributed to the 100 articles, with the Nature journal contributing most of the articles (n=22). The most common country of article origin was the United States of America (n=78), followed by Germany (n=4), Switzerland (n=4), Japan (n=3), Spain (n=2), and United Kingdom (n=2). Conclusions In this study, the 100 most-cited articles in cancer epigenetics were examined, and the contributions from various authors, specialties, and countries were identified. Cancer epigenetics is a rapidly growing scientific field impacting translational research in cancer screening, diagnosis, classification, prognosis, and targeted treatments. Recognition of important historical contributions to this field may guide future investigations.

      Purpose: Research output of once-leading countries in surgical journals is decreasing despite an overall increase of scientific publications by 8% per year. We aimed to assess research outputs of German, Dutch, and Israeli pediatric surgeons in dedicated pediatric surgical journals in order to get insight into trends in pediatric surgical research. Methods: We collected bibliographic information on all original articles in the Journal of Pediatric Surgery, European Journal of Pediatric Surgery, and Pediatric Surgery International in 1985-1988, 2000-2003, and 2015-2018 that had a German, Dutch or Israeli last author from a department of pediatric surgery. Citation counts were obtained from the Web of Science. Results: Research output of German pediatric surgery decreased from 19 manuscripts in 1988 (0.1/surgeon/year) to eight manuscripts in 2017 (0.02/surgeon/year), whereas those of the Netherlands increased from two manuscripts in 1985 (0.08/surgeon/year) to 12 manuscripts in 2016 (0.3/surgeon/year). The declining German research output negatively correlated with increasing numbers of specialist pediatric surgeons for total (τ = -0.54; P = 0.0156) and manuscripts per surgeon (τ = -0.79; P = 0.0001), resulting in a negative trend over time (χ2 = 11.845, P = 0.0006). Analyses of citation patterns revealed that manuscripts by Dutch pediatric surgeons and those published in the Journal of Pediatric Surgery had higher absolute citation counts than the reference category of a German manuscript in the European Journal of Pediatric Surgery. Age-corrected citation rates resembled this result by increasing from 2000 to 2003 ( x ˜ = 0.799, range: 0-3.368) to 2015-2018 ( x ˜ = 2, range: 0-5) (P = 0.035) for the Netherlands. Assessment of manuscript types revealed that the proportion of prospective studies increased in the German sample (χ2 = 5.05, P = 0.0246), but remained the lowest among the comparators. Surprisingly, the proportion of non-clinical manuscripts from Germany also increased over time (χ2 = 4.001, P = 0.0455), whereas it remained constant in both the Netherlands and Israel. Conclusion: German pediatric surgical research output decreased in the last thirty years based on the sample of dedicated pediatric surgical journals, while Dutch productivity increased. Citation rates-as a measure of scientific impact-were associated and increased with Dutch manuscripts. The involved factors remain to be determined and whether this represents a shift toward other journals or mirrors a general development.

      BACKGROUND: Obtaining research funding in Otolaryngology - Head and Neck Surgery (ORL-HNS) can be challenging. In this paper, an analysis of research output in ORL-HNS in Australia and worldwide between 2008 and 2018 was conducted and then adjusted for the number of specialist surgeons in each country.METHODS: Scopus by Elsevier was used to measure research output of Ear, Nose and Throat (ENT) surgeons in Australia between 2008 and 2018. Each individual's career and 10-year h-index was identified and then repeated with self-citations excluded. Total and 10-year citations were also recorded. The top 15 countries in terms of research output in ORL-HNS were also ranked based on the number of ENT articles published in the 10-year period, and then adjusted by the number of actively practicing ENT surgeons per country.
    RESULTS: Between 2008 and 2018, Australia published 1510 articles out of a total global output of 48 613 papers in ORL-HNS with the top 10 authors having an h-index placing them within the world's top 100. Whilst the USA made the greatest total contribution with 12 912 publications, when adjusted for the number of specialist ORL-HNS clinicians in each country, Australia, Canada and India in order topped the rankings.
    CONCLUSION: Australia has established itself as a research leader in the global field of ORL-HNS, publishing more articles per surgeon than any other country between 2008 and 2018. The Australian ORL-HNS Academic Surgeons also rank highly on an individual basis when compared to global peers.

      OBJECTIVE: To investigate the articles in the Annals of Rehabilitation Medicine (ARM) using a bibliometric analysis to verify whether there is a correlation between the topics of interest for expert groups and the public media.METHODS: A total of 1,088 ARM articles from the third issue of 2011 to the third issue of 2019 were analyzed. We conducted a bibliometric analysis of the articles using conventional metrics (CM) and alternative metrics (AM). The CM was investigated by collating the type of publication, number of citations, and the specific field of rehabilitation medicine for each article. The AM was analyzed using the Altmetric Attention Score (AAS) provided by Altmetric, the leading AM company. The correlation between the number of citations and the AAS was tested using the Spearman rank correlation coefficient.
    RESULTS: The combined ratio of original articles and case reports was over 90% in this study; however, the total distribution was significantly different compared to previous bibliometric studies (p<0.05). There were 233 articles that satisfied both conditions of at least one citation and at least one AAS point. The number of citations and the AAS were found to have a statistically significant positive linear correlation on a scatter plot (r=0.216, p=0.001).
    CONCLUSION: There is a significant correlation between AM and CM, which means itis important to increase the dissemination of academic knowledge through the public media and increase the status of the journal by increasing the citation-related index.

      Background: COVID-19 is currently rampant in China, causing unpredictable harm to humans. This study aimed to quantitatively and qualitatively investigate the research trends on coronaviruses using bibliometric analysis to identify new prevention strategies.Methods: All relevant publications on coronaviruses were extracted from 2000-2020 from the Web of Science database. An online analysis platform of literature metrology, bibliographic item co-occurrence matrix builder (BICOMB) and CiteSpace software were used to analyse the publication trends. VOSviewer was used to analyse the keywords and research hotspots and compare COVID-19 information with SARS and MERS information.
    Results: We found a total of 9,760 publications related to coronaviruses published from 2000 to 2020. The Journal of Virology has been the most popular journal in this field over the past 20 years. The United States maintained a top position worldwide and has provided a pivotal influence, followed by China. Among all the institutions, the University of Hong Kong was regarded as a leader for research collaboration. Moreover, Professors Yuen KY and Peiris JSM made great achievements in coronavirus research. We analysed the keywords and identified 5 coronavirus research hotspot clusters.
    Conclusions: We considered the publication information regarding different countries, institutions, authors, journals, etc. by summarizing the literature on coronaviruses over the past 20 years. We analysed the studies on COVID-19 and the SARS and MERS coronaviruses. Notably, COVID-19 must become the research hotspot of coronavirus research, and clinical research on COVID-19 may be the key to defeating this epidemic.

      PURPOSE: We explored whether Altmetric scores (London, UK) correlate with traditional bibliometrics in the oral and maxillofacial surgery (OMS) literature.MATERIALS AND METHODS: This study analyzed the 7 OMS journals with the highest impact factors (IFs) and the 20 most-cited articles within those journals from 2013 and 2016. Citations, Altmetric scores, and media "mentions" were studied. Correlations between Altmetric scores, citations, and IF were examined using Pearson correlation coefficients and descriptive statistics. Twitter account data (San Francisco, CA) also were compared with other metrics.
    RESULTS: There was no correlation between citations and Altmetric scores (r = 0.146, P = .087) or between IF and Altmetric scores (r = 0.139, P = .100) in 2013. Altmetric scores also were not significantly correlated with citations (r = 0.116, P = .176) or IF (r = 0.104, P = .225) in 2016. Total Altmetric scores were 2.5 times higher in 2016 than in 2013, with news outlets, Facebook (Menlo Park, CA), and Twitter showing 257%, 243%, and 307% increases in mentions, respectively.
    CONCLUSIONS: Compared with articles in other fields, OMS articles accrued lower Altmetric scores, representing a paucity of attention garnered on social media outlets. Altmetrics are currently insufficient to replace traditional bibliometrics but can provide valuable information on public acquisition of knowledge, especially in the immediate post-publication interval.

      BACKGROUND: It has been well established that research is not addressing health needs in a balanced way - much more research is conducted on diseases with more burden in high-income countries than on those with more burden in lower-income countries. In this study, we explore whether these imbalances persist and inquire about the possible influence of three factors, namely geography, industry and publication incentives.METHODS: We use WHO data on the Global Burden of Disease as a proxy measure of health needs and bibliometric information as a proxy for research efforts. Scientific publications on diseases were collected from MEDLINE using MeSH terms to identify relevant publications. We used Web of Science to collect author affiliations and citation data. We developed a correspondence table between WHO ICD-10 and MeSH descriptors to compare global health needs and research efforts. This correspondence table is available as supplementary material.
    RESULTS: Research output is heavily concentrated in high-income countries and is mainly focused on their health needs, resulting in a relative lack of attention to diseases in lower income countries. A new finding is that diseases with a similar burden in high- and middle-income countries are also under-researched, both globally and in relation to disease burden in high- and middle-income countries. Global industrial R&D is found to be very similar to the focus of public research. Diseases more prevalent in high-income countries generate ten-fold more research attention than those in low-income countries. We find no discernible preference towards diseases of high-income countries versus those of low-income countries in the top 25% most prestigious journals. However, in middle-income countries, citation rates are substantially lower for diseases most prevalent in low- and middle-income countries.
    CONCLUSIONS: From a global perspective, the imbalance between research needs and research efforts persists as most of the research effort concentrates on diseases affecting high-income countries. Both pharmaceutical companies and the public sector also tend to focus on diseases with more burden in high-income countries. Our findings indicate that researchers in middle-income countries receive more citations when researching diseases more prevalent in high-income countries, and this may divert the attention of researchers in these countries from diseases more prevalent in their contexts.

      Background: National Natural Science Foundation of China (NSFC) plays a vital role promoting advancement of science in China. The incidence and mortality rate of valvular heart disease (VHD) increase with aging population. Therefore, it is of significance to discuss the development and trend in the field of VHD and provide references for scholars to carry out further Foundations.Methods: Internet-based Science Information System and other websites were used to search for projects supported by NSFC related to VHD in 2008-2019 and related information of applicants. Publications, citations and impact factors were queried by Google Scholar and InCites Journal Citation Reports 2.0 and analyzed by SPSS for Windows version 24.0. Key words extracted from these project titles were imported into Citespace for analysis.
    Results: A total of 117 projects and related information were acquired. Although the annual amount of projects and funding has fluctuated in recent years, they still maintained an upward trend. Institutes were mainly distributed over Hubei Province, Shanghai and Jiangsu Province. Applicants characterized as senior title, male, cardiac surgeon have accounted for a larger proportion of projects, with a greater amount of funding. Through the analysis of keywords and subject distribution, molecular-biology-based mechanism study combined with tissue engineering has become the principal research hot spot and trend in recent years. Annual changes in output in scientific research were consistent with changes in the amount of funding.
    Conclusions: This paper collated funding situation supported by NSFC in VHD, analyzed distribution of keywords and summarized the research trend, so as to supply guidance to researchers for advanced researches.

      This study surveys the development of Alzheimer's disease (AD) in the research literature, the scientific community, and the journals containing AD papers over a 35-year period. Research papers on AD published from 1983 to 2017 in journals indexed in the Web of Science were analyzed in seven five-year periods. The number of AD papers increased from 1,095 in 1983-1987 to 50,532 by 2013-2017 and in the same time period, the number of participating countries went from 27 to 152. The US was the most prolific country throughout, followed by several European countries, Canada, Australia, and Japan. Asian countries have emerged and by 2013-2017, China surpassed all but the US in productivity. Countries in Latin America and Africa have also contributed to AD research. Additionally, several new non-governmental institutions (e.g., ADNI, ADI) have emerged and now play a key role in the fight against AD. Likewise the AD scientific publishing universe evolved in various aspects: an increase in number of journals containing AD papers (227 journals in 1983-1987 to 3,257 in 2013-2017); appearance of several AD-focused journals, e.g., Alzheimer's & Dementia, Journal of Alzheimer's Disease; and the development of special issues dedicated to AD. Our paper complements the numerous extant papers on theoretical and clinical aspects of AD and provides a description of the research landscape of the countries and journals contributing papers related to AD.

      Background: It is imperative that researchers studying medical tourism connect their work with policy, so that its real-world challenges can be better understood, and more effectively addressed. This article gauges the scope and evolution of policy thinking in medical tourism research through a bibliometric review of published academic literature, to establish the extent to which researchers apply public policy theories and frameworks in their investigation of medical tourism, or consider the policy imperatives of their work.Methods: A Boolean search of the Web of Science (WoS) Core Collection was performed to identify policy-related publications on medical tourism. We analyzed the results using bibliometrics and a data visualization software called VOSviewer to identify patterns in knowledge production and underlying network linkages in policy research on the subject.
    Results: Our findings suggest that only a small proportion of medical tourism research explicitly addresses policy issues or applies policy paradigms in their study approach. Field-specialized journals serving practitioners publish less research as compared to interdisciplinary social and health policy journals. Moreover, there are significant geographical and disciplinary disparities in the policy-orientation of research, and a predilection towards select policy areas such as reproductive and transplant tourism to the neglect of more holistic governance and health system considerations.
    Conclusion: This article is a call to action for greater engagement by policy scholars on medical tourism, and for health researchers to more explicitly consider how their research might contribute to the understanding and resolution of contemporary policy challenges of medical tourism. Failure to clearly and consistently make the policy connection is a lost opportunity for researchers to frame the public debate, and influence policy thinking on medical tourism.

      OBJECTIVE: Twenty-one previous studies have shown a mean presentation to publication conversion rates at radiology conferences of 26%. There have been no prior studies on publication of medical imaging residency research presentations. Our objective was to determine how many medical imaging resident research projects presented at internal program research days across Canada go on to publication.METHODS: A list of unique medical imaging resident research presentations given at program research days during the 2012-2013 to 2016-2017 academic years was generated via e-mail contact of programs or review of publicly available data on program websites. Unique resident presentations were identified and publications associated with these presentations were sought via database and Internet searching. The number of publications, publishing journals, and time to publication was determined.
    RESULTS: Data from 32 research days at 7 programs were assessed. A total of 287 resident presentations were identified. Of these 287 presentations, 99 had associated publications (34% presentation to publication conversation rate), with variation in presentation numbers and publication conversion rates between schools. These 99 presentations were associated with a total of 118 publications in a total of 57 different journals. Time from presentation to publication was calculable for 109 of the 118 articles. Fifteen (14%) were published before research day and 94 (86%) were published after research day with a mean time to publication of 12.3 ± 13.6 months for all articles.
    CONCLUSIONS: Thirty-four percent of resident research presentations at Canadian medical imaging program research days go on to publication.

      BACKGROUND: Randomized controlled trials (RCTs) provide the highest level of evidence and are likely to influence clinical decision-making. This study evaluated the reporting quality of RCT abstracts on drug therapy of periodontal disease and assessed the associated factors.MATERIAL AND METHODS: The Pubmed database was searched for periodontal RCTs published in Science Citation Indexed (SCI) dental journals from 2010/01/01 to 2019/07/17. Information was extracted from the abstracts according to a modified Consolidated Standards of Reporting Trials (CONSORT) guideline checklist. The data was analyzed using descriptive statistical analysis and the statistical associations were examined using the linear regression analysis (P<0.05).
    RESULTS: This study retrieved 1715 articles and 249 of them were finally included. The average overall CONSORT score was 15.6 ± 3.4, which represented 40.9% (±0.6) of CONSORT criteria filling. The reporting rate of some items (trial design, numbers analyzed, confidence intervals, intention-to-treat analysis or per-protocol analysis, harms, registration) was less than 30%. The adequate reporting rate of some items (participants, randomization, numbers analyzed, confidence intervals, intention-to-treat analysis or per protocol analysis) was no more than 4%. None of the abstracts reported funding. According to the multivariable linear regression results, number of authors (P=0.030), word count (P<0.001), continent (P=0.003), structured format (P<0.001), type of periodontal disease (P<0.001) and international collaboration (P=0.023) have a significant association with reporting quality.
    CONCLUSIONS: The quality of RCT abstracts on drug therapy of periodontal disease in SCI dental journals remained suboptimal. More efforts should be made to improve RCT abstracts reporting quality.

      2019 commemorates the 10 year anniversary of the National Academy of Sciences report, "Strengthening Forensic Science in the United States: A Path Forward," and one valuable way to measure progress in forensic science is through published research. The purpose of this study is to examine where the friction ridge discipline stands with respect to published research. Two time periods were selected (2005-2009 and 2010-2014) and two different methods were used to describe research growth and publication trends in this discipline. A bibliometric review was conducted using an online literature-indexing tool, Web of Science™, as well as an empirical method involving subject matter experts. Both methods showed an increased number of friction ridge articles published in scientific journals over time.

      Objective: This study evaluated the bibliometric data of the most common publication types of the neuroimaging literature. Methods: PubMed was searched to identify all published papers with "neuroimaging" as their MeSH Major Topics, and they were further searched by the following publication types: case report, clinical trial, comparative study, editorial, evaluation study, guideline, meta-analysis, multicenter study, randomized controlled trial, review, technical report, and validation study. The proportion of papers belonging to each publication type published in neuroimaging journals was calculated. Year-adjusted mean citation counts for each publication type were computed using data from Web of Science. Publication trend and its correlation with citation performance were assessed. Results: Review and comparative study were the most common publication types. Publication types with the highest proportion in neuroimaging journals were guideline, validation study, and technical reports. Since the year 2000, multicenter study, review, and meta-analysis showed the strongest linear increase in annual publication count. These publication types also had the highest year-adjusted citation counts (4.7-10.0). Publication types with the lowest year-adjusted citation counts were editorial and case report (0.5-1.0). It was estimated that 12.5% of the publications labeled as case reports were incorrectly labeled. Conclusions: Neuroimaging literature has been expanding with papers of higher levels of evidence, such as meta-analyses, multicenter studies, and randomized controlled trials.

      Computers were introduced into nursing care areas in the early 1950s; however, nursing informatics' historical roots emerged much earlier. Contrary to previous studies, which used manual review of the nursing informatics literature, we employed an automated, electronic approach with specialized software to identify its historical roots. The corpus of nursing informatics literature was harvested from Scopus using "informatic*" in information source titles, abstracts, and keywords, limited to the "subject area = nursing." The search resulted in 3805 publications containing 57 057 valid references. Fifteen historical sources were identified, the two oldest written by nursing pioneer Florence Nightingale. Other historical roots represent specific foundational and core scholarly works offering insight into the genesis and sustainment of particular bodies of literature in the field of informatics. Our study revealed that the field of nursing informatics has sought to respond to global health concerns and that through intensive development nursing informatics has become an independent research area affecting nursing advancements in general. Additionally, nursing informatics has influenced other disciplines. This study offered an in-depth look at nursing informatics literature, using a systematic approach to identify historical roots and analyze the evolution of topics and themes to gain more information about knowledge development in nursing informatics.

      BACKGROUND: Over the past few years, efforts have been made to ensure that the teachers of the Faculty of Medicine of Tunis (FMT) cite their affiliation to the FMT and the University of Tunis El Manar in addition to their hospital institutions and their research structure in their publications.AIMS: In this study, we proposed to evaluate the FMT's membership in the publications of its teachers, to identify the different types of publications and to estimate the real number.
    METHODS: In this bibliometric cross-sectional study, we retrieved the FMT publications indexed in medline/pubmed database (1964-June2019). We have chosen the keywords corresponding to the publications of group1 (referenced FMT) and group2 (referenced FMT or annexed hospital-university institutions). Next, we calculated the rate of group1 on group2 and sorted the different types of items in group2. Finally, We estimated, after randomization, the actual number of FMT publications for a 99% confidence interval (99% CI).
    RESULTS: For groups 1 and 2, 1477 and 5194 publications were retrieved, respectively. The FMT membership rate averaged 28% ranging from 4% (1990-2010) to 44% (2011-2019). Of the FMT publications, 30% were free of charge and 55% were original articles. After a draw for 300 group2 publications, the estimated number of total FMT publications was between 4519 and 4934 for a 99% CI.
    CONCLUSIONS: It is essential to mention its affiliation to «the Faculty of Medicine of Tunis» and to «the University of Tunis El Manar» in order to improve the visibility and ranking of our two academic institutions.

      BACKGROUND: There is a continued need to evaluate training programs in dissemination and implementation (D&I) research. Scientific products yielded from trainees are an important and objective measure to understand the capacity growth within the D&I field. This study evaluates our mentored training program in terms of scientific productivity among applicants.METHODS: Post-doctoral and early-career cancer researchers were recruited and applied to the R25 Mentored Training for Dissemination and Implementation Research in Cancer (MT-DIRC) between 2014 and 2017. Using application details and publicly available bibliometric and funding data, we compared selected fellows with unsuccessful applicants (nonfellows). We extracted Scopus citations and US federal grant funding records for all applicants (N = 102). Funding and publication abstracts were de-identified and coded for D&I focus and aggregated to the applicant level for analysis. Logistic regression models were explored separately for the odds of (1) a D&I publication and (2) US federal grant funding post year of application among fellows (N = 55) and nonfellows (N = 47). Additional models were constructed to include independent variables that attenuated the program's association by 5% or more. Only US-based applicants (N = 87) were included in the grant funding analysis.
    RESULTS: Fellows and nonfellows were similar across several demographic characteristics. Fellows were more than 3 times more likely than nonfellows to have grant funding after MT-DIRC application year (OR 3.2; 95% CI 1.1-11.0) while controlling for time since application year; the association estimate was 3.1 (95% CI 0.98-11.0) after adjusting for both cancer research area and previous grant funding. For publications, fellows were almost 4 times more likely to publish D&I-focused work adjusting for time (OR 3.8; 95% CI 1.7-9.0). This association lessened after adjusting for previous D&I publication and years since undergraduate degree (OR 2.9; 95% CI 1.2-7.5).
    CONCLUSIONS: We document the association of a mentored training approach with built-in networks of peers to yield productive D&I researchers. Future evaluation efforts could be expanded to include other forms of longer-term productivity such as policy or practice change as additional objective measures. D&I research trainings in the USA and internationally should consider common evaluation measures.

      The use of medicinal plants has been done since ancient times and may even be considered the origin of modern medicine. Compounds of plant origin have been and still are an important source of compounds for drugs. In this study a bibliometric study of all the works indexed in the Scopus database until 2019 has been carried out, analyzing more than 100,000 publications. On the one hand, the main countries, institutions and authors researching this topic have been identified, as well as their evolution over time. On the other hand, the links between the authors, the countries and the topics under research have been analyzed through the detection of communities. The last two periods, from 2009 to 2014 and from 2015 to 2019, have been examined in terms of research topics. It has been observed that the areas of study or clusters have been reduced, those of the last period being those engaged in unclassified drug, traditional medicine, cancer, in vivo study-antidiabetic activity, and animals-anti-inflammatory activity. In summary, it has been observed that the trend in global research is focused more on the search for new medicines or active compounds rather than on the cultivation or domestication of plant species with this demonstrated potential.

      Homicide is the most serious form of violence with a negative impact on the population. It is broadly studied in the scientific field and disseminated in print and in the virtual media. The scope of this article is to locate papers in national and international journals, seeking the synthesis of knowledge and the incorporation of the applicability of the results of significant studies. It involved an integrative review of the SciELO, PubMed and LILACS databases of articles published between 2006 and 2016. The following key words were researched: Homicide and Brazil. The publications were selected by the title, abstract and methodology. For homicide and health studies in Brazil, 427 papers were found, of which 98 were selected. There were publications with emphasis on the national scenario, followed by the state of São Paulo and Pernambuco. The quantitative study was the most used, with collection of secondary data. The papers dealt with homicides in the population in general (48%), Femicide (14.3%) and Social Determinants (7.1%). The Brazilian scientific production on homicide and health is on the increase. It is important that researchers, analysts and editors turn their attention to the development of papers in this area, aiming to improve the quality of published articles.

      The Brazilian Congress of Soil Science (Congresso Brasileiro de Ciência do Solo - CBCS) is the oldest soil science event in South America. The CBCS had 29,643 participants and 23,621 publications in 30 thematic areas between 1947 and 2017. There were only five editions of the CBCS (1947-1979) in which Soil Fertility did not produce the highest number of papers. Standardization of Soil Study Methods and Representation/Soil Teaching was the most prolific in one year, and Soil Genesis, Morphology, and Cartography produced the most papers in the other four years. Subsequently, the area renamed as Soil Fertility and Plant Nutrition had the highest number of papers. By grouping papers into the scientific divisions of the Brazilian Society of Soil Science (Sociedade Brasileira de Ciência do Solo - SBCS), we verify that the division of Soil Use and Management had the most papers in most congresses. In 2017, the number of papers and the number of male researchers in the Brazilian National Council for Scientific and Technological Development were associated for each thematic area. The trends in CBCS publications were influenced by the natural and historic-economic characteristics of the country, in addition to changes that occurred in SBCS, universities, research institutes, and legislation.

      BACKGROUND: The objective of this study was to compare middle authorships between male and female general surgeons in the United States.METHODS: A stratified random sample of American College of Surgeons general surgery fellows was identified. Relevant author demographic, affiliation, and publication metrics were collected and compared across cohorts to determine which demographics were prognostic for each outcome variable. The primary endpoint was the number of middle author papers between genders.
    RESULTS: Males were more likely to enter into practice earlier (p<0.001), be fellowship-trained (p<0.001), obtain higher academic rank (p<0.001), and practice at more highly ranked academic institutions (p=0.019). Females had fewer middle author publications (p=0.044) and higher annual rates of first author publications (p=0.020) despite similar rates of total publications.
    CONCLUSIONS: Female surgeons hold the middle author position less frequently than males despite similar total publication numbers. Reasons for this finding should be the target of future study.
