Mean Impact Factor Research Articles

Finite Element Analysis Generates an Increasing Interest in Dental Research: A Bibliometric Study.

Purpose:The purpose was to provide a longitudinal overview of published studies that use finite element analysis in dental research, by using the SCI-expanded database of Web of Science® (Thomson Reuters). Material and Methods:Eighty publications from 1999-2000 and 473 from 2009-2010 were retrieved. This literature grew faster than the overall dental literature. The number of publishing countries doubled. The main journals were American or English, and dealt with implantology. For the top 10 journals publishing dental finite element papers, the mean impact factor increased by 75% during the decade. Results:Finite elements generate an increasing interest from dental authors and publishers worldwide.

Analysis of Chinese nursing articles published in international nursing journals

Objective To evaluate the quantity and quality of articles in international nursing journals from China, and to investigate Chinese authors′ contribution to the field of nursing worldwide. Methods Webs of Science were used to identify the articles in International Nursing Journals from mainland China, Taiwan and Hong Kong and abroad from 2010 to 2014. The number of articles, impact factor and citation were analyzed. Results A total of 1 639 articles were published from China (373 from mainland China, 985 from Taiwan, and 281 from Hong Kong) between 2010 and 2014. The annual publications from mainland China showed a significant increase trend (reached 2.64 times, P 0.05). Taiwan had the highest total impact factor and total citations. Hong Kong had the highest mean impact factor and mean citation. Conclusions There is a significant increase in the number of articles from mainland of China in recent years. Taiwan is the region with the most publication and highest influence in Chinese nursing, while Hong Kong has the highest quality of articles in terms of mean impact factor and mean citation. Key words: China; International; Literature; Journal of Nursing

Publication rate of paper and podium presentations from the European Section of the Cervical Spine Research Society Annual Meeting

The Cervical Spine Research Society Europe (CSRS-E) actively promotes scientific activities, the annual meeting being the most evident of them. The publication rate of oral and poster presentations at the annual meeting could be a measure for the success of the promotional activities. The publication rates of abstracts presented at the annual European meetings of the CSRS are unknown. The quality of the abstracts presented at a conference is reflected by the publication rate. A high publication rate is usually interpreted as representative of high scientific value of the conference. Poster and podium presentations from the 2007 to 2012 annual meetings were identified. Pubmed was used to search for the abstract title and/or the combination of authors to verify whether the data were published in a peer-reviewed journal. Abstracts were considered published if the data presented at the meeting were identical to that in the publication. The journals in which the data were published were identified, as well as the origin of the research centre. From 2007 to 2012 826 abstracts were featured at the CSRS Europe annual meetings. There were 236 podium presentations and 590 poster presentations. 42% of the podium presentations resulted in a publication, and 28% of the poster presentations led to a publication. Overall, 32% of accepted abstracts effectuated a publication in a peer-reviewed scientific journal. Abstracts from European research groups had a publication rate of 29% compared to 34% for abstracts from non-European research groups. Spine, European Spine Journal, Journal of Spinal Disorders and Techniques and J Neurosurgery Spine were the most common publication journals for the abstracts. The mean impact factor of the journals in which was published was 2.2. 42% of the abstracts that were accepted for podium presentation at the CSRS Europe resulted in a publication in peer-reviewed MEDLINE indexed journals. Publication rates are at the high end of the publication rate spectrum of abstracts accepted for European scientific meetings.

Trends in impact factors of ophthalmology journals.

Purpose:To test whether there is an association between the growth in the number of ophthalmic journals in the past years and their mean and maximum impact factor (IF) as a common sign of scientific proliferation.Methods:Using data from the 2013 Journal Citation Report database a study of the major clinical medical fields was conducted to assess the correlation between the number of journals and maximum IF in a given field in the year 2013. In the field of ophthalmology, we examined the correlation between year, number of journals, mean IF and maximum IF in the field of ophthalmology throughout the years 2000–2013.Results:In the major medical fields, a positive correlation was found between the number of journals and the maximum IF (quadratic R2 = 0.71, P < 0.001). When studying the field of ophthalmology a positive correlation between the number of journals and mean IF (R2 = 0.84, P < 0.001) and between number of journals and maximum IF (R2 = 0.71, P < 0.001) was detected.Conclusions:Our findings suggest that the variation in the IF can be explained by the number of journals in the field of ophthalmology. In the future, the formation of additional ophthalmology journals is likely to further increase the IFs of existing journals.

Publicaciones de la comunidad endoscópica mexicana, su número, tipo e impacto en la literatura mundial

IntroductionMexico is in 24th place among the 40 countries with the highest number of publications in the biomedical area, however the productivity by specific medical specialties is not known. The aim of this article was to describe the number of endoscopy publications by the Mexican community, including the type and its impact on world literature. Material and methodsA search was conducted in PubMed of all publications from national hospitals in the area of gastrointestinal endoscopy in the period 2010-2015. The following were taken into consideration: Original articles, meta-analysis, case-control studies, case series (more than 4 patients), case reports, and letters to the editor containing original information generated in a national centre with or without the participation of foreign doctors. ResultsA total of 77 papers were included in the analysis. The areas of endoscopy with more publications were panendoscopy (gastroscopy) 37 (48.1%), endoscopic ultrasound 13 (16.9%), ERCP 6 (20.8%), colonoscopy 6 (7.8%), videocapsule 4 (5.2%), and enteroscopy one (1.3%) article. The mean impact factor of the journals in which there is at least one Mexican study published was 2.9. The median of citations per article was 2 (1-43). The average number of publications per site was 3.2 (1-22). ConclusionThe number of publications on endoscopy in the Mexican community is low, and impact on the world stage is limited in scope.

The fate of research abstracts submitted to a national surgical conference: a cross-sectional study to assess scientific impact

BackgroundConference abstracts often lack rigorous peer review, but potentially influence clinical thinking and practice. To evaluate the quality of abstracts submitted to a large surgical conference, presentation and publication rates were investigated to assess scientific impact. MethodsA Cross-sectional study of abstracts submitted to Dutch Surgical Society meetings from 2007 to 2012 was conducted. Presentation rates, publication rates in MEDLINE-indexed journals using PubMed Central database, and actuarial times to subsequent publication were investigated. ResultsOf 2,174 submitted abstracts, 1,305 (60%) abstracts were accepted for presentation. Actuarial 1, 3, and 5-year publication rates were 22.4%, 62.2%, and 68.6% for presented abstracts, compared with 20.9%, 50.3%, and 57.7% for rejected abstracts, respectively (log-rank x2 23.728, df1, P < .001). Publications resulting from abstracts presented at the conference had a significantly higher mean (±standard error) impact factor (4.4 ± .2 vs 3.4 ± .1, P < .001), compared with publications from previously rejected abstracts. ConclusionsWe advocate critical appraisal of the use of findings of scientific abstracts and conference presentations. The 5-year abstract-to-publication ratio is proposed as a novel quality indicator to allow objective comparison between scientific meetings.

A comparative analysis of scientific publications in management journals by authors from Mainland China, Hong Kong, Taiwan, and Macau: 2003–2012

The purpose of this paper is to compare the quantity and quality of management articles published in international journals by authors from the four major regions of China. The results showed that both the quality and quantity of papers published in management journals from ML, HK, and TW greatly improved from 2003 to 2012. Publication from MC also increased. TW exceeded ML and HK in the accumulated factors. HK and TW had the highest mean impact factor. ML published the most papers, and the most frequently cited paper came from ML. However, publications from ML were unevenly distributed among the provinces.

A Survey of Scientific Outputs of Iranian Researchers in the Field of Poisonous Animals in Web of Science: a Scientometric Study

ISI Web of Science (WOS) is the world's most prestigious database that is used in order to evaluate and rank the countries, researchers, institutions, and universities. Therefore, determining the status of Iranian articles in this database in the field of poisonous and venomous animals is important. Quantitative and qualitative assessments of scientific outputs are the main goals of this study. In order to conduct this research, 220 articles written by Iranian researchers during 1973 to 2010 in the field of poisonous animals which have been indexed in Web of Science were reviewed. Scientometric, survey and citation analysis methods have been used. In this research, number of papers in different years, annual growth rate of papers, international collaboration of Iranian researchers with their counterparts from other countries, impact factor, average citation per paper in comparison with some selected countries, subject categories, and the most prolific institutes and authors have been surveyed. Results of the present study showed that from 2004 onwards, the number of papers increasingly enhanced. The most collaboration of Iranian authors has been done respectively with their counterparts and colleagues from USA, Belgium and Scotland; Poisonous animals articles have had the most interaction with the fields of toxicology and pharmacology. The mean impact factor was 1.731 and the average citation per paper was 4.15. Tehran University, Razi Vaccine and Serum Research Institute, Tehran University of Medical Sciences and Tarbiat Modarres University were the most Iranian prolific universities and institutes respectively. Number of articles in the field of poisonous animals has been increased significantly in recent years. The most collaboration was with USA and European countries respectively. The average citation per paper of Iranian articles in poisonous animals is lower than selected countries. Besides universities, Razi Vaccine and Serum Research Institute, is among the most prolific universities and institutes. The mean impact factor of Iran in poisonous animals has relatively good position in comparison with other fields of Iran, but lower than other fields in some mentioned countries.

Turkish endocrine surgery publications in international scientific journals.

In recent years, major progress has been made in the field of endocrine surgery in Turkey, similar to that in the rest of the world. Parallel to these developments, there has been a significant increase in the number of publications in the related field. Our study aimed to evaluate Turkey's publications related to endocrine surgery in the international arena. Members of the general surgery departments from academic centers in Turkey were determined. Using these member names, a PubMed search was performed for English papers related to "endocrine surgery." For searching papers from non-academic centers, the same engine was used. To reach manuscripts possibly missed by the PubMed search, 3 national calls were made through the website of the Turkish Society of Endocrine Surgery. The obtained papers were divided into "thyroid," "parathyroid," "adrenal," and "neuroendocrine tumors" and were listed according to the publication year. In addition, all manuscripts were listed according to the publishing journal and the 2012 impact factor of that journal. This study did not require ethical approval, because it did not involve evaluation of experimental or patient data. A search of Turkish general surgery clinics revealed 497 international publications, between 1976 and 2012. When listed according to the year of publication, most publications were found to be in the year 2009. Papers appeared mostly in "Surgery Today." The mean impact factor of the journals where the papers have been published was 1.9 (0.1-13.8). The rates of thyroid, parathyroid, adrenal tissue and neuroendocrine tumors related publications were 69%, 10%, 15% and 6%, respectively. Since this study is not an experimental study or a study related to patient data, we did not apply for ethical approval. The contribution of Turkish general surgeons' to world science is apparent when evaluated in terms of publications related to endocrine surgery until recently. Particularly, since 2002, with the increase in the number of publications in the field of endocrine surgery, there has been an increase in Turkey's importance on the international platform.

Growing trend of China's contribution to the field of spine: a 10-year survey of the literature.

China, as a rapidly developing country with the largest population including over 50,000 orthopaedic surgeons, has an increasing importance in the field of spine. However, the quantity and quality of research production in the field of spine in the major regions of China-Mainland China, Taiwan, and Hong Kong is unclear. This study aimed to investigate the contribution of China to the field of spine. Articles published in the 5 major spine journals originating from Mainland China, Taiwan and Hong Kong in 2004-2013 were retrieved from the database of Web of Science. The number of articles, impact factors, citations, article type, city, institution, funding source and conflict of interest were analyzed. There were 1006 publications in the 5 spine journals between 2004 and 2013 from China, including 706 from Mainland China, 210 from Taiwan, and 90 from Hong Kong. The time trend of the number of articles from these three regions showed a significant increase of 8.74-fold (from 23 to 201) between 2004 and 2013 (p = 0.000). From 2006, the number of publications from Mainland China exceeded Taiwan and Hong Kong. Mainland China had the highest total impact factors (1686.54) and total citations (4214), followed by Taiwan (498.93; 2009) and Hong Kong (222.89; 1311). Hong Kong had the highest mean impact factor (2.48) and mean citations (14.46), followed by Mainland China (2.40; 10.26) and Taiwan (2.38; 10.14). The journal Spine published the largest number of articles (470), followed by European Spine Journal (268). Chinese contributions to the field of spine have a significant increase during the past 10 years, particularly from Mainland China. Hong Kong had the highest quality research output in terms of mean impact factor and mean citation per article.

The state of the art on European well-being research within the area of mental health

As part of A Roadmap for Mental Health Research in Europe project, the aim of the present study was to perform a systematic mapping of the main publications in peer-reviewed journals for well-being research within the area of mental health or mental disorders in Europe. The PubMed and PsycINFO databases were used to identify papers on well-being within the area of mental health and mental disorders published from January 2007 to September 2014. Mean 5-year impact factors were obtained. The number of publications for each country was analysed by population size and gross domestic product (GDP). A total of 4,423 unique publications were identified. The number of publications increased for the analysed time period. France and the Netherlands had the highest 5-year mean impact factor. Publications per capita were higher in the Nordic countries, Ireland and the Netherlands. After adjusting for GPD, the most productive countries were the Nordic countries and the Netherlands. There is a marked variation in well-being publications by country in Europe. Eastern European countries produce little research taking into consideration the levels of resources available. Research on older adults was underrepresented and should be prioritised.

Management Learning: The journal for critical, reflexive scholarship on organization and learning

The journal’s 2-year impact factor currently stands at 1.25 and the 5-year impact factor at 1.89 in the Thomson Reuters Journal Citation Reports (2014). In terms of 5-year trends, the journal’s mean 2-year impact factor stands at a healthy 1.37. As far as journal quality lists go, we await with interest the outcome of the revision to the United Kingdom’s Association of Business School (ABS) journal quality list to see how things stand. Further afield, the Australian Business Dean’s Council (ABDC) Journal Quality List (2013) rated Management Learning as an ‘A’ journal. However, the ABDC is right to remind us that journal lists should be only a starting point for assessing quality, and that there is no substitute for assessing the scholarship of a piece of work on a case-by-case basis. In this latter regard, the outcome of the United Kingdom’s Research Excellence Framework (unknown at the time of writing this Editorial) may also shed light on the quality, impact, and relevance of Management Learning scholarship. Management Learning has a long and respected history, the first issue being published in 1970 under the name of Management Education and Development. In 1994, the journal title changed to Management Learning, and in 2009, we celebrated our 40 th anniversary. We entered our fifth decade with the conviction and optimism that the type of scholarship the journal publishes “continues to be different” from the scholarship to be found in the mainstream management journals or that of the journals we consider our closest “relatives.” Perhaps better known in the UK, Australasia and Europe, we continually seek to expand our reach to North America and Asia to provide a forum for scholars wishing to challenge mainstream work. But we still struggle against the perception that we are a pedagogic teaching and learning journal—which clearly we are not. Rather, we publish innovative critical and reflexive scholarly work around learning, managing, and organizing—a philosophy that can be traced back to Mark Easterby-Smith and Mike Pedler’s 1986 Editorial, when in

Conversion rates of abstracts to publications from the Irish Society of Urology Annual Meeting (2005–2011) – Questioning the scientific value of national urological meetings for smaller European nations

Background: Large annual scientific meetings such as the American Urological Association (AUA) and the European Association of Urology (EUA) have abstract conversion rates into publication of 37%−48%. There are no data on the conversion rates from national meetings of smaller European countries. Our objective was to present the conversion rates and manuscript characteristics of the Irish Society of Urology (ISU) annual meeting over a seven-year period (2005–2011), and to demonstrate the value, viability and sustainability of such a meeting as a model for other small national research programmes. Methods: All abstracts presented at the ISU annual meeting between 2005 and 2011 were identified. The subsequent publication rate following the meetings was established for the corresponding studies based on a Medline scan. A range of characteristics associated with subsequent publication were analysed using the logistic regression of the dichotomous variable of publications vs. non-publication of each factor. Results: Overall, 46% of the 322 abstracts presented at the ISU meeting were followed by publication into Medline-indexed journals with a mean impact factor of 2.6. A total of 74% abstracts were published within two years. Oral presentations were more likely to be published than posters ( p &lt; 0.0001), and prospective clinical research was more likely to be published in a journal with a higher impact factor than retrospective analyses ( p = 0.033); the mean time to publication was 16.7 months. Conclusions: Almost half the abstracts presented at the ISU were subsequently published in peer-reviewed journals, the majority within two years. This compares favourably with larger urological meetings, and provides an incentive to other smaller countries within Europe to continue with national research programmes.

The emerging use of Twitter by urological journals.

To assess the emerging use of Twitter by urological journals. A search of the Journal of Citation Reports 2012 was performed to identify urological journals. These journals were then searched on Twitter.com. Each journal website was accessed for links to social media (SoMe). The number of 'tweets', followers and age of profile was determined. To evaluate the content, over a 6-month period (November 2013 to April 2014), all tweets were scrutinised on the journals Twitter profiles. To assess SoMe influence, the Klout score of each journal was also calculated. In all, 33 urological journals were identified. Eight (24.2%) had Twitter profiles. The mean (range) number of tweets and followers was 557 (19-1809) and 1845 (82-3692), respectively. The mean (range) age of the twitter profiles was 952 (314-1758) days with an average 0.88 tweets/day. A Twitter profile was associated with a higher mean impact factor of the journal (mean [sd] 3.588 [3.05] vs 1.78 [0.99], P = 0.013). Over a 6-month period, November 2013 to April 2014, the median (range) number of tweets per profile was 82 (2-415) and the median (range) number of articles linked to tweets was 73 (0-336). Of these 710 articles, 152 were Level 1 evidence-based articles, 101 Level 2, 278 Level 3 and 179 Level 4. The median (range) Klout score was 47 (19-58). The Klout scores of major journals did not exactly mirror their impact factors. SoMe is increasingly becoming an adjunct to traditional teaching methods, due to its convenient and user-friendly platform. Recently, many of the leading urological journals have used Twitter to highlight significant articles of interest to readers.

A bibliometric analysis of diets and breast cancer research.

Breast cancer is the most common cancer among women worldwide. The primary aim of this work was to provide an in-depth evaluation of research publications in the field of diets and breast cancer. The impact of economic outcome on national academic productivity was also investigated. Data were retrieved using Pubmed for English-language publications. The search included all research for which articles included words relating to "diets and breast cancer". Population and national income data were obtained from publicly available databases. Impact factors for journals were obtained from Journal Citation Reports® (Thomson Scientific). There were 2,396 publications from 60 countries in 384 journals with an impact factor. Among them, 1,652 (68.94%) publications were Original articles. The United States had the highest quantity (51% of total) and highest of mean impact factor (8.852) for publication. Sweden had the highest productivity of publication when adjusted for number of population (6 publications per million population). Publications from the Asian nation increased from 5.3% in 2006 to 14.6% in 2012. The Original article type was also associated with geography (p<0.001; OR=2.183; 95%CI=1.526-3.123), Asian countries produced more proportion of Original articles (82%) than those of rest of the world (67.6%). Diets and breast cancer-associated research output continues to increase annually worldwide including publications from Asian countries. Although the United States produced the most publications, European nations per capita were higher in publication output.

Family medicine publications in Taiwan: An analysis of the Web of Science database from 1993 to 2012

BackgroundAcademic publications are important for developing a medical specialty or discipline. Since family medicine is a rapidly growing medical specialty in Taiwan, this study aimed to analyze family medicine publications from 1993 to 2012 in Taiwan using the Web of Science database. MethodsPublished academic articles submitted from departments/institutes of family medicine were retrieved and analyzed from the Web of Science database, which includes articles published in the Science Citation Index–Expanded and Social Science Citation Indexed journals from 1993 to 2012. ResultsAmong 33,073 published articles submitted from the departments/institutes of family medicine worldwide during the years 1993–2012, 1552 articles (4.69%) were submitted from Taiwan, ranking fourth in the world after the USA, Canada, and Sweden. In total, 1409 articles from Taiwan, excluding meeting abstracts and corrections, were selected for further analyses. During these two decades, family medicine publications increased rapidly. There were 60 articles published during 1993–1997, 180 articles during 1998–2002, 334 articles during 2003–2007, and up to 836 articles during 2008–2012. However, the mean citation number of articles decreased from 19.0 to 17.7, 15.1, and 3.8, and the mean impact factor of published journals decreased from 3.41 to 3.15, 2.78 and 2.82 during the periods 1993–1997, 1998–2002, 2003–2007, and 2008–2012, respectively. Most articles belonged to the subject category of the Medicine, General and Internal category (194 articles, 13.8%), followed by Public Environmental Occupational Health (144 articles, 10.2%), Oncology (126 articles, 9.2%), Endocrinology Metabolism (111 articles, 7.9%), Geriatrics Gerontology (99 articles, 7.0%), and the Gastroenterology Hepatology category (85 articles, 6.0%). However, only six articles (0.4%) were published in the Primary Health Care category. ConclusionPublications from departments/institutes of family medicine in Taiwan increased rapidly from 1993 to 2012. However, the trends of decreased citation number of articles and journal impact factor, as well as the small amount of articles published in the Primary Health Care Category, deserve further attention and effort.

An analysis of references used for the Orthopaedic In-Training Examination: what are their levels of evidence and journal impact factors?

Although the references recommended for the Orthopaedic In-Training Examination (OITE) have been evaluated in certain subspecialty domains, suggested reference level of evidence (LOE), impact factor, and citation age have not been evaluated comprehensively to our knowledge. We present an analysis of all references cited in the OITE recommended readings for each test question including the duration of time between their initial publication and their use in the OITE, which we defined as citation age, LOE, and the impact factor of the journals referenced. We evaluated all references for the 2010 to 2012 OITE administrations (three examinations; 825 questions total). Publication characteristics, including citation age, were noted. The LOE for each journal article and the impact factor of each journal were determined; differences in LOE and impact factor were compared between test sections. A total of 1817 references were cited in the 825 questions we evaluated; this denominator was used in all calculations that follow. The recommended reading references included 1337 journal article references (74%), 469 text references (26%), and 11 multimedia sources (0.6%; eg, websites, instructional DVDs). The three most commonly recommended journals were general orthopaedic journals, The Journal of Bone and Joint Surgery (American Volume), Journal of American Academy of Orthopaedic Surgeons, and Clinical Orthopaedics and Related Research. The majority (72.2%) of the cited journal references were published within 10 years of the test date, with a mean ± SD citation age of 8.3 ± 7.4 years. The majority of the cited journal articles were Levels IV and V evidence (mean, 4.16 ± 1.1). The Spine section had higher LOE (3.74; p < 0.001), although the practical relevance of such a difference is questionable, as all but two sections' LOE rounded to Level IV evidence. The Spine and Basic Science sections were published in journals with a larger mean impact factor (Basic Science, 7.16 ± 12.67; Spine, 5.73 ± 12.08; p < 0.001). Our data show that the majority of the recommended readings for the OITE stem from higher impact general orthopaedic and major subspecialty journals. Furthermore the observed mean LOE of the recommended readings shows a preponderance of Levels IV and V research. These data may suggest that test-takers may find benefit in the review of high-level general orthopaedic journals, and review articles in particular while preparing for the OITE, although further study is necessary to determine optimal test preparation strategies. Finally, our study provides a baseline analysis of the study designs of OITE recommended references, and may provide insight for educators designing resident educational curricula.

Bibliometrics of intraoperative radiotherapy: analysis of technology, practice and publication tendencies.

To analyze the performance and quality of intraoperative radiation therapy (IORT) publications identified in medical databases during a recent period in terms of bibliographic metrics. A bibliometric search was conducted for IORT papers published in the PubMed database between 1997 and 2013. Publication rate was used as a quantity indicator; the 2012 Science Citation Index Impact Factor as a quality indicator. Furthermore, the publications were stratified in terms of study type, scientific topic reported, year of publication, tumor type and journal specialty. We performed a one-way analysis of variance (ANOVA) to determine differences between the means of the analyzed groups. Among the total of 207 journals, articles were reported significantly more frequently in surgery (n = 399, 41 %) and radiotherapy journals (n = 273, 28 %; p < 0.01). The highest impact factor was achieved by clinical oncology journals (p < 0.01). The majority of identified articles were retrospective cohort reports (n = 622, 64 %), followed by review articles (n = 204, 21 %; p < 0.001). Regarding primary topic, reports on cancer outcome following specific tumor therapy were most frequently published (n = 661, 68 %; p < 0.001) and gained the highest mean impact factor (p < 0.01). Gastrointestinal tumor reports were represented most frequently (n = 456, 47 %; p < 0.001) and the mean superior impact factor was earned by breast and gynecologic publications (p < 0.01). We identified a consistent and sustained scientific productivity of international IORT expert groups. Most publications appeared in journals with surgical and radiooncological content. The highest impact factor was achieved by medical oncology journals.

Public mental health research in Europe: a systematic mapping for the ROAMER project.

As part of the ROAMER (ROAdmap for MEntal health Research in Europe) project, aiming to create an integrated European roadmap for mental health research, we set out to map the hitherto unmapped territory of public mental health research in Europe. Five electronic databases (CINAHL, Health Management, Medline, PsycINFO, Social Services Abstracts) were used for identifying public mental health research articles published between January 2007 and April 2012. The number of publications for each European country in five research domains (i.e. mental health epidemiology, mental health promotion, mental disorder prevention, mental health policy and mental health services) was analysed by population size and gross domestic product (GDP), and mean impact factors were compared. In all, 8143 unique publications were identified. Epidemiology research dominates public mental health research, while promotion, prevention and policy research are scarce. Mental health promotion is the fastest growing research area. Research targeting older adults is under-represented. Publications per capita were highest in northwestern Europe, and similar trends were found also when adjusting the number of publications by GDP per capita. The most widely cited research origins from Italy, Switzerland, the UK, the Nordic countries, the Netherlands, Greece and France. In Europe, public mental health research is currently a matter of the affluent northern and western European countries, and major efforts will be needed to promote public mental health research in south and east Europe. In spite of a smaller public mental health research output, some Mediterranean countries produce highly cited public mental health research.

Errata in Medical Publications

BackgroundInformation is limited about the communication of corrections or errors in the medical literature; therefore, we sought to determine the frequency and significance of published errata in high impact factor journals. MethodsRetrospective evaluation of errata reports for articles published in 20 English-language general medicine and cardiovascular journals (mean impact factor, 12.23; median, 5.52) over 18 months. Each independently adjudicated erratum was categorized by location in the article and qualitative categories of severity. Descriptive statistics and Spearman's rank correlation coefficients were computed to describe the association between author and errata number. Source of error, association between impact factor and errata occurrence, and errata rate by journal were assessed. ResultsA total of 557 articles were associated with errata reports (overall errata report occurrence 4.2 per 100 published original and review articles; mean of 2.4 errors per errata report). At least 1 major error that materially altered data interpretation was present in 24.2% of articles with errata. There was a strong association between impact factor and errata occurrence rate (rho = 0.869, P < .001). Across all errata, 51.0% were not corrected or the report did not specify whether a correction was made. ConclusionsThe reporting of errata across journals lacks uniformity. Despite published criteria for authorship that mandate final approval of the manuscript by all authors, errors are frequent, including those that may materially change the interpretation of data. Increased vigilance by authors to prevent errata and consensus by journal editors on the format of reporting are warranted.
