2016-05-01
This study aimed to assess the most common publication types in radiology journals, as well as temporal trends and association with citation frequency. PubMed was searched to extract all published articles having the following "Publication Type" indices: "validation studies," "meta-analysis," "clinical trial," "comparative study," "evaluation study," "guideline," "multicenter study," "randomized study," "review," "editorial," "case report," and "technical report." The percentage of articles within each category published within clinical radiology journals was computed. Normalized percentages for each category were also computed on an annual basis. Citation counts within a 2-year window following publication were obtained using Web of Science. Overall trends were assessed. Publication types with the highest fraction in radiology journals were technical reports, evaluation studies, and case reports (4.8% to 5.8%). Publication types with the lowest fraction in radiology journals were randomized trials, multicenter studies, and meta-analyses (0.8% to 1.5%). Case reports showed a significant decrease since 1999, with accelerating decline since 2007 (P = 0.002). Publication types with highest citation counts were meta-analyses, guidelines, and multicenter studies (8.1 ± 10.7 to 12.9 ± 5.1). Publication types with lowest citation counts were case reports, editorials, and technical reports (1.4 ± 2.4 to 2.9 ± 4.3). The representation in radiology journals and citation frequency of the publication types showed weak inverse correlation (r = -0.372). Radiology journals have historically had relatively greater representation of less frequently cited publication types. Various strategies, including methodological training, multidisciplinary collaboration, national support networks, as well as encouragement of higher level of evidence by funding agencies and radiology journals themselves, are warranted to improve the impact of radiological research.

A history of music therapy journal articles published in the English language.
Brooks, Darlene
2003-01-01
Music therapists have had an interest in bibliographic research for over 20 years, beginning with Jellison's 1973 analysis of the frequency and types of articles appearing in the existing music therapy literature. Since then, several other researchers have continued in this line of inquiry. The purpose of this study was to (a) identify historical trends in the types of articles that have been published in major music therapy periodicals in the English language, (b) identify historical trends for each type of article within each music therapy journal, (c) to compare percentages of article types within each music therapy journal and (d) to compare percentages of article types across journals. Specifically, how many quantitative, qualitative, historical, philosophical/theoretical, clinical and professional articles have been published throughout the history of the following journals: Journal of Music Therapy, Music Therapy: Journal of the American Association for Music Therapy, Music Therapy Perspectives, The Arts in Psychotherapy, Journal of the Association for Music & Imagery, The Australian Journal of Music Therapy, The Nordic Journal of Music Therapy, The British Journal of Music Therapy, and The New Zealand Society for Music Therapy Journal.

Mapping the literature of hospital pharmacy.
Barrett, Ann; Helwig, Melissa; Neves, Karen
2016-04-01
This study describes the literature of hospital pharmacy and identifies the journals most commonly cited by authors in the field, the publication types most frequently cited, the age of citations, and the indexing access to core journals. The study also looks at differing citation practices between journals with a wide audience compared to a national journal with a focus on regional issues and trends in the field. Cited references from five discipline-specific source journals were collected and analyzed for publication type and age. Two sets were created for comparison. Bradford's Law of Scattering was applied to both sets to determine the most frequently cited journals. Three-quarters of all cited items were published within the last 10 years (71%), and journal articles were the most heavily cited publication type (n=65,760, 87%). Citation analysis revealed 26 journal titles in Zone 1, 177 journal titles in Zone 2, and the remaining were scattered across 3,886 titles. Analysis of a national journal revealed Zone 1 comprised 9 titles. Comparison of the 2 sets revealed that Zone 1 titles overlapped, with the exception of 2 titles that were geographically focused in the national title. Hospital pharmacy literature draws heavily from its own discipline-specific sources but equally from core general and specialty medical journals. Indexing of cited journals is complete in PubMed and EMBASE but lacking in International Pharmaceutical Abstracts. Gray literature is a significant information source in the field.

To determine the characteristics of medical education studies published in general and internal medicine (GIM) and medical education journals, and to analyze the accuracy of their indexing. The authors identified the five GIM and five medical education journals that published the most articles indexed in MEDLINE as medical education during January 2001 to January 2010. They searched Ovid MEDLINE for evaluative medical education studies published in these journals during this period and classified them as quantitative or qualitative studies according to MEDLINE indexing. They also examined themes and learner levels targeted. Using a random sample of records, they assessed the accuracy of study-type indexing. Of 4,418 records retrieved, 3,853 (87.2%) were from medical education journals and 565 (12.3%) were from GIM journals. Qualitative studies and program evaluations were more prevalent within medical education journals, whereas GIM journals published a higher proportion of clinical trials and systematic reviews (χ=74.28, df=3, P<.001). Medical education journals had a concentration of studies targeting medical students, whereas GIM journals had a concentration targeting residents; themes were similar. The authors confirmed that 170 (56.7%) of the 300 sampled articles were correctly classified in MEDLINE as evaluative studies. The majority of the identified evaluative studies were published in medical education journals, confirming the integrity of medical education as a specialty. Findings concerning the study types published in medical education versus GIM journals are important for medical education researchers who seek to publish outside the field's specialty journals.

Evidence-based practice has become an imperative for efficient, effective and safe practice. Furthermore, evidences emerging from published research are considered as valid knowledge sources to guiding practice. The aim of this paper is to review all research articles published in the top 10 general nursing journals for the years 2000-2006 to identify the methodologies used, the types of evidence these studies produced and the issues upon which they endeavored. Quantitative content analysis was implemented to study all published research papers of the top 10 general nursing journals for the years 2000-2006. The top 10 general nursing journals were included in the study. The abstracts of all research articles were analysed with regards the methodologies of enquiry, the types of evidence produced and the issues of study they endeavored upon. Percentages were developed as to enable conclusions to be drawn. The results for the category methodologies used were 7% experimental, 6% quasi-experimental, 39% non-experimental, 2% ethnographical studies, 7% phenomenological, 4% grounded theory, 1% action research, 1% case study, 15% unspecified, 5.5% other, 0.5% meta-synthesis, 2% meta-analysis, 5% literature reviews and 3% secondary analysis. For the category types of evidence were 4% hypothesis/theory testing, 11% evaluative, 5% comparative, 2% correlational, 46% descriptive, 5% interpretative and 27% exploratory. For the category issues of study were 45% practice/clinical, 8% educational, 11% professional, 3% spiritual/ethical/metaphysical, 26% health promotion and 7% managerial/policy. Published studies can provide adequate evidences for practice if nursing journals conceptualise evidence emerging from non-experimental and qualitative studies as relevant types of evidences for practice and develop appropriate mechanisms for assessing their validity. Also, nursing journals need to increase and encourage the publication of studies that implement RCT methodology, systematic reviews, meta-synthesis and meta-analysis methodologies. Finally, nursing journals need to encourage more high quality research evidence that derive from interpretative, theory testing and evaluative types of studies that are practice relevant.

The objective of this study was to analyze and record the published evidence regarding community pharmacy practice in India during the past decade (1998-2008). A bibliometric review analysis of the original papers was undertaken to assess the different aspects of community pharmacy practice in India. The MEDLINE, Index Copernicus, IndMed, DOAJ databases and the journals such as Indian Journal of Pharmaceutical Sciences and Indian Journal of Hospital Pharmacy were used as data sources. Type of papers, type of journals, category of papers, production indicators and impact factor of the journals were analyzed. Thirty papers were included in the study. The papers were published in 13 different journals, 33.3% of them being in the Indian Journal of Hospital Pharmacy. The average number of authors per paper was 2.73 (SD=1.41). Impact factor was available for only three journals. There are limited studies being published in India which cover the community pharmacy related activities in India. The key indicators which emerge from the literature review present some fundamental challenges to the development of the role of the community pharmacist in India.

Objectives: The purpose of this study was to identify (1) core journals in the literature of physical therapy, (2) currency of references cited in that literature, and (3) online databases providing the highest coverage rate of core journals. Method: Data for each cited reference in each article of four source journals for three years were recorded, including type of literature, year of publication, and journal title. The journal titles were ranked in descending order according to the frequency of citations and divided into three zones using Bradford's Law of Scattering. Four databases were analyzed for coverage rates of articles published in the Zone 1 and Zone 2 journals in 2007. Results: Journal articles were the most frequently cited type of literature, with sixteen journals supplying one-third of the cited journal references. Physical Therapy was the most commonly cited title. There were more cited articles published from 2000 to 2007 than in any previous full decade. Of the databases analyzed, CINAHL provided the highest coverage rate for Zone 1 2007 publications. Conclusions: Results were similar to a previous study, except for changes in the order of Zone 1 journals. Results can help physical therapists and librarians determine important journals in this discipline. PMID:21753912

In this study, we aimed to investigate whether studies published in orthodontic journals and titled as randomized clinical trials are truly randomized clinical trials. A second objective was to explore the association of journal type and other publication characteristics on correct classification. American Journal of Orthodontics and Dentofacial Orthopedics, European Journal of Orthodontics, Angle Orthodontist, Journal of Orthodontics, Orthodontics and Craniofacial Research, World Journal of Orthodontics, Australian Orthodontic Journal, and Journal of Orofacial Orthopedics were hand searched for clinical trials labeled in the title as randomized from 1979 to July 2011. The data were analyzed by using descriptive statistics, and univariable and multivariable examinations of statistical associations via ordinal logistic regression modeling (proportional odds model). One hundred twelve trials were identified. Of the included trials, 33 (29.5%) were randomized clinical trials, 52 (46.4%) had an unclear status, and 27 (24.1%) were not randomized clinical trials. In the multivariable analysis among the included journal types, year of publication, number of authors, multicenter trial, and involvement of statistician were significant predictors of correctly classifying a study as a randomized clinical trial vs unclear and not a randomized clinical trial. From 112 clinical trials in the orthodontic literature labeled as randomized clinical trials, only 29.5% were identified as randomized clinical trials based on clear descriptions of appropriate random number generation and allocation concealment. The type of journal, involvement of a statistician, multicenter trials, greater numbers of authors, and publication year were associated with correct clinical trial classification. This study indicates the need of clear and accurate reporting of clinical trials and the need for educating investigators on randomized clinical trial methodology.

A Cross-Sectional Analysis of Publication Types in Quality Improvement Journals.
Wong, Christopher J; White, Andrew A; Merel, Susan E; Brock, Douglas M; Staiger, Thomas O
2016-07-01
Despite widespread engagement in quality improvement activities, little is known about the designs of studies currently published in quality improvement journals. This study's goal is to establish the prevalence of the types of research conducted in articles published in journals dedicated to quality improvement. A cross-sectional analysis was performed of 145 research articles published in 11 quality improvement journals in 2011. The majority of study designs were considered pre-experimental (95%), with a small percentage of quasi-experimental and experimental designs. Of the studies that reported the results of an intervention (n = 60), the most common research designs were pre-post studies (33%) and case studies (25%). There were few randomized controlled trials or quasi-experimental study designs (12% of intervention studies). These results suggest that there are opportunities for increased use of quasi-experimental study designs. © The Author(s) 2015.

The quality of harms reporting in journal publications is often poor, which can impede the risk-benefit interpretation of a clinical trial. Clinical study reports can provide more reliable, complete, and informative data on harms compared to the corresponding journal publication. This case study compares the quality and quantity of harms data reported in journal publications and clinical study reports of orlistat trials. Publications related to clinical trials of orlistat were identified through comprehensive literature searches. A request was made to Roche (Genentech; South San Francisco, CA, USA) for clinical study reports related to the orlistat trials identified in our search. We compared adverse events, serious adverse events, and the reporting of 15 harms criteria in both document types and compared meta-analytic results using data from the clinical study reports against the journal publications. Five journal publications with matching clinical study reports were available for five independent clinical trials. Journal publications did not always report the complete list of identified adverse events and serious adverse events. We found some differences in the magnitude of the pooled risk difference between both document types with a statistically significant risk difference for three adverse events and two serious adverse events using data reported in the clinical study reports; these events were of mild intensity and unrelated to the orlistat. The CONSORT harms reporting criteria were often satisfied in the methods section of the clinical study reports (70-90 % of the methods section criteria satisfied in the clinical study reports compared to 10-50 % in the journal publications), but both document types satisfied 80-100 % of the results section criteria, albeit with greater detail being provided in the clinical study reports. In this case study, journal publications provided insufficient information on harms outcomes of clinical trials and did not specify that a subset of harms data were being presented. Clinical study reports often present data on harms, including serious adverse events, which are not reported or mentioned in the journal publications. Therefore, clinical study reports could support a more complete, accurate, and reliable investigation, and researchers undertaking evidence synthesis of harm outcomes should not rely only on incomplete published data that are presented in the journal publications.

This study examines the distribution of health outcomes research (HOR) studies in the clinical literature by clinical areas and journal impact factor. The authors reviewed 535 journals and divided the sample into higher and lower impact journals across four clinical area. Mann-Whitney and Kruskal-Wallis tests were used to examine differences across four categories of outcomes research articles published, specifically the incidence of articles in higher versus lower impact journals and differences across clinical areas. All high-impact journals published more safety and quality articles than process assessment, quality of life, or cost analysis studies. The number of each type of outcomes research study published was highly variable across all clinical areas. Only arthritis and outcomes research journals showed statistically significant differences between higher versus lower impact journals. Authors may benefit from considering these differences in their clinical specialty area when deciding where to submit HOR studies.

Plagiarism remains a scourge for the modern academia. There are inconsistencies in the plagiarism policy scientific journals. The aims of this study was to analyze types of published articles on 'Plagiarism' available on PubMed over last two decades against a backdrop of the plagiarism policy of the journals publishing such articles. A literature search on PubMed (https://www.ncbi.nlm.nih.gov/pubmed) was made using the search term "plagiarism" from 01 January 1997 till 29 March 17. All publications having 'plagiarism' in the title formed the study group. The following were noted: types of articles published, ethical and plagiarism policy of the journal as available in the Instructions to authors and or in the journal home page. A total of 582 publications from 320 journals were studied. Editorials (165, 28.3%) and Letters to the Editor (159, 27.3%) formed the bulk. Research articles (56, 9.6%), Review articles (51, 8.7%) and Commentaries (47, 8%) formed the remainder. Detailed ethical guidelines were present in 221 (69%). Outline ethical guidelines only were present in 15 (4.7%) journals. 49 (15.3%) journals did not have any ethical guidelines. Detailed description of the policy on plagiarism was found in 80 (25%) journals. Only an outline description was found in 29 (9%) journals while a plagiarism policy/statement was totally absent in 176 (55%) journals. There is a need to have a well defined plagiarism policy/statement for all scholarly journals easily visible on their home pages on the internet and also in their Instructions to Authors.

The objective of this study was to examine the article production on psychosis from the main spanish journals of psychology and psychiatry, as well as to make comparisons among them. 16 journals of psychology and 5 of psychiatry were selected and a period of revision of four years settled down (2003-2006). The sample was constituted by 183 articles. For the comparison of the journals four index were used: proportion of articles on psychosis in relation to the total of generated articles; used type of methodology; used type of sample; and aspect of the psychosis in whose investigation it is centered. The results show that little is investigated, that most of the studies is theoretical or ex- post facto, that more the frequently studied subjects are those with psychosis and that the taken care of aspects more are related to the etiology and the treatment of the disease.
Low power and type II errors in recent ophthalmology research.

To investigate the power of unpaired t tests in prospective, randomized controlled trials when these tests failed to detect a statistically significant difference and to determine the frequency of type II errors. Systematic review and meta-analysis. We examined all prospective, randomized controlled trials published between 2010 and 2012 in 4 major ophthalmology journals (Archives of Ophthalmology, British Journal of Ophthalmology, Ophthalmology, and American Journal of Ophthalmology). Studies that used unpaired t tests were included. Power was calculated using the number of subjects in each group, standard deviations, and α = 0.05. The difference between control and experimental means was set to be (1) 20% and (2) 50% of the absolute value of the control's initial conditions. Power and Precision version 4.0 software was used to carry out calculations. Finally, the proportion of articles with type II errors was calculated. β = 0.3 was set as the largest acceptable value for the probability of type II errors. In total, 280 articles were screened. Final analysis included 50 prospective, randomized controlled trials using unpaired t tests. The median power of tests to detect a 50% difference between means was 0.9 and was the same for all 4 journals regardless of the statistical significance of the test. The median power of tests to detect a 20% difference between means ranged from 0.26 to 0.9 for the 4 journals. The median power of these tests to detect a 50% and 20% difference between means was 0.9 and 0.5 for tests that did not achieve statistical significance. A total of 14% and 57% of articles with negative unpaired t tests contained results with β > 0.3 when power was calculated for differences between means of 50% and 20%, respectively. A large portion of studies demonstrate high probabilities of type II errors when detecting small differences between means. The power to detect small difference between means varies across journals. It is, therefore, worthwhile for authors to mention the minimum clinically important difference for individual studies. Journals can consider publishing statistical guidelines for authors to use. Day-to-day clinical decisions rely heavily on the evidence base formed by the plethora of studies available to clinicians. Prospective, randomized controlled clinical trials are highly regarded as a robust study and are used to make important clinical decisions that directly affect patient care. The quality of study designs and statistical methods in major clinical journals is improving overtime, 1 and researchers and journals are being more attentive to statistical methodologies incorporated by studies. The results of well-designed ophthalmic studies with robust methodologies, therefore, have the ability to modify the ways in which diseases are managed.

Background Transparency in reporting of conflict of interest is an increasingly important aspect of publication in medical journals. Publication of large industry-supported trials may generate many citations and journal income through reprint sales and thereby be a source of conflicts of interest for journals. We investigated industry-supported trials' influence on journal impact factors and revenue. Methods and Findings We sampled six major medical journals (Annals of Internal Medicine, Archives of Internal Medicine, BMJ, JAMA, The Lancet, and New England Journal of Medicine [NEJM]). For each journal, we identified randomised trials published in 1996–1997 and 2005–2006 using PubMed, and categorized the type of financial support. Using Web of Science, we investigated citations of industry-supported trials and the influence on journal impact factors over a ten-year period. We contacted journal editors and retrieved tax information on income from industry sources. The proportion of trials with sole industry support varied between journals, from 7% in BMJ to 32% in NEJM in 2005–2006. Industry-supported trials were more frequently cited than trials with other types of support, and omitting them from the impact factor calculation decreased journal impact factors. The decrease varied considerably between journals, with 1% for BMJ to 15% for NEJM in 2007. For the two journals disclosing data, income from the sales of reprints contributed to 3% and 41% of the total income for BMJ and The Lancet in 2005–2006. Conclusions Publication of industry-supported trials was associated with an increase in journal impact factors. Sales of reprints may provide a substantial income. We suggest that journals disclose financial information in the same way that they require them from their authors, so that readers can assess the potential effect of different types of papers on journals' revenue and impact.

The aim of this research was to study the trends in authorship and type of article in European and North American journals of urology over the past 6 decades. Using a self-developed Visual Basic program, the number of authors per article and the type of article in four European journals (BJU International, Current Opinion in Urology, European Urology and Urologia Internationalis) and four North American journals (Journal of Urology, Urologic Clinics of North America, Urology and World Journal of Urology) were extracted from the PubMed website from January 1946 to October 2010, and the number of authors per article in each year was calculated in all the journals. The average number of authors per article has increased and the percentage of single-author articles has decreased in both European and American journals. An increase in the number of authors per article was observed mainly in original articles and case reports. Since the early 1980s, there has also been a decreasing percentage of published case reports and a general increase in the percentage of letters to the editor and editorials. The multiple-authorship trends observed in both European and North American urology journals were similar and appeared to be mainly due to changes in original articles and case reports.

Diagnosis checking of statistical analysis in RCTs indexed in PubMed.
Lee, Paul H; Tse, Andy C Y
2017-11-01
Statistical analysis is essential for reporting of the results of randomized controlled trials (RCTs), as well as evaluating their effectiveness. However, the validity of a statistical analysis also depends on whether the assumptions of that analysis are valid. To review all RCTs published in journals indexed in PubMed during December 2014 to provide a complete picture of how RCTs handle assumptions of statistical analysis. We reviewed all RCTs published in December 2014 that appeared in journals indexed in PubMed using the Cochrane highly sensitive search strategy. The 2014 impact factors of the journals were used as proxies for their quality. The type of statistical analysis used and whether the assumptions of the analysis were tested were reviewed. In total, 451 papers were included. Of the 278 papers that reported a crude analysis for the primary outcomes, 31 (27·2%) reported whether the outcome was normally distributed. Of the 172 papers that reported an adjusted analysis for the primary outcomes, diagnosis checking was rarely conducted, with only 20%, 8·6% and 7% checked for generalized linear model, Cox proportional hazard model and multilevel model, respectively. Study characteristics (study type, drug trial, funding sources, journal type and endorsement of CONSORT guidelines) were not associated with the reporting of diagnosis checking. The diagnosis of statistical analyses in RCTs published in PubMed-indexed journals was usually absent.

The purpose of our study was to investigate authorship trends in radiology journals, and whether International Committee of Medical Journal Editors (ICMJE) recommendations have had an impact on these trends. A secondary objective was to explore other variables associated with authorship trends. A retrospective, bibliometric analysis of 49 clinical radiology journals published from 1946-2013 was conducted. The following data was exported from MEDLINE (1946 to May 2014) for each article: authors' full name, year of publication, primary author institution information, language of publication and publication type. Microsoft Excel Visual Basics for Applications scripts were programmed to categorize extracted data. Statistical analysis was performed to determine the overall mean number of authors per article over time, impact of ICMJE guidelines, authorship frequency per journal, country of origin, article type and language of publication. 216,271 articles from 1946-2013 were included. A univariate analysis of the mean authorship frequency per year of all articles yielded a linear relationship between time and authorship frequency. The mean number of authors per article in 1946 (1.42) was found to have increased consistently by 0.07 authors/ article per year (R² = 0.9728, P<0.001) to 5.79 authors/article in 2013. ICMJE guideline dissemination did not have an impact on this rise in authorship frequency. There was considerable variability in mean authors per article and change over time between journals, country of origin, language of publication and article type. Overall authorship for 49 radiology journals across 68 years has increased markedly with no demonstrated impact from ICMJE guidelines. A higher number of authors per article was seen in articles from: higher impact journals, European and Asian countries, original research type, and those journals who explicitly endorse the ICMJE guidelines.

The presentation of scientific studies at major meetings serves to rapidly share study results with the scientific community. On the other hand, full-text publication of abstracts in peer-reviewed journals ensures the dissemination of science. This study examines the publication rate (PR) of meeting abstracts presented at the European Society for Surgical Research (ESSR) congresses and determines/compares the factors affecting the PRs. All presentations at the ESSR congresses held during 2008-2011 were retrospectively assessed. Manuscripts indexed in PubMed were included. The meeting year, journal impact factor (IF) in the publication year, study type, presentation type, time to publication and geographic origin of studies were assessed. Among a total of 1,368 oral and poster abstracts, 48.7% (n = 391) of the oral presentations (OPs) and 29.7% (n = 168) of the poster presentations (PPs) were published in medical journals indexed in PubMed. The mean IF of the journals was 2.696 (0.17-14.95). The journals that published OPs had a higher IF than the journals in which PPs were published (2.944 vs. 2.118; p < 0.001). The PR was also higher in the OP group than in the PP group of journals (p < 0.001). The time to publication was 17.5 months (-166 to 82) and was shorter for PPs than for OPs (14.02 vs. 19.09 months; p = 0.01). According to the study type, experimental studies had a significantly higher PR (53.7%; p < 0.001); however, there was no significant difference in PR in terms of the prospective or retrospective nature of clinical studies. The clinical studies were also compared according to the IF values of the journals in terms of the prospective or retrospective nature of the study, and no significant difference was found (p = 0.62). The ESSR congress is an efficient meeting for researchers from varied surgical disciplines and has a PR equivalent to that of similar scientific meetings. The congress has achieved a PR of 40.9% over 4 years with an average IF of 2.696 and a mean time to publication of 17.5 months, which is equivalent to that of similar scientific meetings. OPs have a higher PR in journals with greater IF values as compared with PPs. © 2016 S. Karger AG, Basel.

To compare the statistical methods, types of article and design of studies used in 1998 and 2007 articles of leading indexed and non-indexed medical journals of Pakistan. Six leading medical journals of Pakistan: (1) JCPSP, (2) JPMA, (3) JAMC, (4) PJMS, (5) PJMR and (6) PAFMJ, were selected for this study. Articles reviewed were 1057 to achieve the above mentioned objective. The articles reviewed for 1998 and 2007 were 366 and 691, respectively. Original articles contributed the maximum percentage of 65.6%, followed by case reports with 24.8%. The contribution of case reports in 1998 was 20.5% which increased to 27.1% in 2007. There was no statistically significant difference between 'indexed' and 'non-indexed' journals for different type of statistical methods in 1998 or 2007. In total, 749 articles were categorized as 'original articles' or 'short communication'. Among them, 51% articles mentioned study design and 67.3% of them were correct for the respective methodology. In 1998, 202 (74%) articles did not use any statistics or indicated only descriptive statistics, while in 2007, 239 (50.2%) articles did the same. The reader who was familiar with t-test and contingency tables in 1998 could have understood 97.4% of the scientific articles. However, this percentage dropped to 83.0% in 2007. Quality of elaborating methods and usage of biostatistics in 6 leading Pakistani medical journals improved from 1998 to 2007, but has still to come up as compared to other western medical journals.

The impact of a publication in a particular medical area is reflected by the number of times the article is included as a citation. It is not known, however, which articles are cited the most in primary care journals. In our study, we aimed to identify the 100 most cited articles in primary care medicine and analyze their characteristics.We searched the Science Citation Index Expanded for articles published in 18 primary care journals using the subject category "Primary health care." We identified 100 articles in primary health care that were the most cited. We analyzed the characteristics of these articles using the title, number of citations, citation density, year of publication, journal source, decade published, country of origin, institution, author names, and type of article.The 100 articles that were cited the most were published between the years 1977 and 2009. The 1990s decade was the most productive decade. The number of citations ranged from 117 to 775. The articles were published in 9 journals and the journal with the largest number of most cited articles (n = 33) was the Journal of Family Practice. This was followed by the British Journal of General Practice (n = 17) and the journal Family Practice (n = 16). The United States was the most productive country (n = 59); the United Kingdom was next (n = 25) and this was followed by Canada (n = 5) and The Netherlands (n = 5). The most popular article type was a review article and this was followed by a qualitative study and then methodological study.Our study provides insight into the historical development of primary care studies, based on citations, and provides the foundation for further investigations.

The question of who pays for research to be conducted and published is an important one as it may result in publication bias. The traditional model of medical publishing has relied on subscriptions for funding. There has been increasing interest in making the results of scientific research freely available. One proposed mechanism is an author-pays system, which shifts cost from subscribers to authors. We investigated the impact of author page charges on the nature and type of published research, and the association of industry funding with types of published research. Four infectious diseases journals with comparable scope were studied-two with page charges and two without. Variables included type of research study, area of research, author demographics, study setting and industry funding. The differences between a subscription model vs. a mixed model (author page charges and subscription charges) were studied. We also investigated changes within the same journal once it had moved from a subscription model to a mixed model. Authors from developing countries were significantly less likely to be published in the mixed-model journals (OR 0.25, 95% CI 0.15-0.41, P < 0.001). Clinical trials published in any type of journal were significantly more likely to be industry funded than any other type of research (OR 12.7, 95% CI 7.0-22.9, P < 0.001). Industry-funded research was significantly less likely to be about diseases affecting predominantly the developing world (OR 0.47, 95% CI 0.25-0.89, P < 0.05). There is clearly a relationship between industry funding and certain types of published research. The model of funding of journal publishing can also affect the nature of published research. Shifting publishing costs to authors favours well-funded organizations, industry sponsored research and wealthy countries. Such potential for publication bias must be considered when planning for open access models.

To examine the supporting evidence of advertisements published in six leading orthodontic journals. The 2012-2013 printed issues of American Journal of Orthodontics and Dentofacial Orthopedics, Australian Orthodontic Journal, Journal of Orthodontics, European Journal of Orthodontics, Journal of Clinical Orthodontics, and Journal of Orofacial Orthopedics were screened for advertisements implying superior performance compared with competitor products. Advertisements were classified according to type of product, availability, and currency of supporting references. A total of 99 unique advertisements claiming clinical benefit or superiority were identified. The overwhelming majority of the identified advertisements promoted appliance products (62.6%), orthodontic materials (14.1%), and dental operatory equipment, including imaging systems (12.1%). Advertisements were found to provide references or not regardless of the product type. Half of the advertisements referred to at least one peer-reviewed publication, whereas unpublished studies were cited by 25% of the advertisements. Most of the referenced articles were published within the past 5 years. The scientific background of advertisements in the orthodontic literature appears limited. While surveillance of journal advertising needs to be regulated, clinicians are urged to critically appraise the claims being made in orthodontic print advertisements by consulting the associated existing evidence.

Journals are an important method for disseminating research findings and other evidence for practice to nurses. Bibliometric analyses of nursing journals can reveal information about authorship, types of documents cited, and how information is communicated in nursing, among other characteristics. The purposes of our study were to describe the types of documents used to develop the clinical and research literature in nursing, and extent of gray literature cited in those publications. This was a descriptive study of 18,901 citations of articles in clinical specialty and research journals in nursing published between January 2004 and June 2005. The research team reviewed each citation to assess if the cited document was a journal article, book chapter or book, or document falling into the category of gray literature. Frequency counts for each type of cited document were recorded. Most of the citations were to journal articles (n=14,392, 76.1%) and among those, to articles in medical journals (n=7719, 40.8% of all the citations). This was true for the literature as a whole and for the clinical specialty and research literature separately. Although citations to medical journals were most common, in the clinical nursing literature there was a significantly higher proportion of citations to medical journal articles (n=6332, 44.5%) than in the nursing research literature (n=1387, 29.7%) (LR(X)(2)=326.7, p<0.0001). Nearly 10% of the citations were to gray literature. There was an increase in citations to websites (5.7%) compared to a study done only a few years earlier. Our study documented that journal literature was the primary source of information for communication within nursing. This is consistent with other biomedical and hard sciences where the transfer, assimilation, and use of information occur mainly within the scientific community. With a reliance on journal articles for dissemination of research and evidence for clinical practice, improved methods will be needed for integrating this knowledge and presenting it in a usable form to clinicians. As journals proliferate, it will become increasingly difficult for clinicians to keep current with research findings to guide their practice. The development and testing of new methods for integrating and disseminating research evidence to busy clinicians will be increasingly important in nursing. Gray literature was nearly 10% of the citations. The study also revealed an increase in citations to websites, which is anticipated to continue in the future. Further study is needed on the indexing of gray literature relevant to research use and evidence-based practice in nursing and on how to make this literature easily available to clinicians.
Publication rates following pancreas meetings.

2001-08-01
Publication rates and determinants of publication were studied based on abstracts presented at pancreatic meetings. All abstracts presented at the 1994 and 1995 annual meetings of the European Pancreatic Club (EPC) and the American Pancreatic Association (APA) were followed up by searching MEDLINE. Publication rates were compared using log-rank tests and multiple logistic regression. The prestige of the publishing journals was compared using Kruskal-Wallis tests on scientific impact factors (SIF). Overall, 340 abstracts were presented at the EPC, and 254 were presented at the APA. Of these, 203 (59.7%, EPC) and 138 (54.3%, APA) were later published in peer-reviewed journals. Publication rates did not differ by study type or country region of origin. In addition, median SIFs were similar by conference (APA vs. EPC) and research type (basic science vs. clinical studies) (overall, 1.7). However, North American and North/West European articles were published in higher impact journals as compared with those from other countries. Publication rates and median journal SIFs in pancreas research are similar to those reported from other medical specialty meetings. There is no difference by conference, type of research, or origin (North American vs. European).

Publications in anesthesia journals: quality and clinical relevance.
Lauritsen, Jakob; Moller, Ann M
2004-11-01
Clinicians performing evidence-based anesthesia rely on anesthesia journals for clinically relevant information. The objective of this study was to analyze the proportion of clinically relevant articles in five high impact anesthesia journals. We evaluated all articles published in Anesthesiology, Anesthesia & Analgesia, British Journal of Anesthesia, Anesthesia, and Acta Anaesthesiologica Scandinavica from January to June, 2000. Articles were assessed and classified according to type, outcome, and design; 1379 articles consisting of 5468 pages were evaluated and categorized. The most common types of article were animal and laboratory research (31.2%) and randomized clinical trial (20.4%). A clinically relevant article was defined as an article that used a statistically valid method and had a clinically relevant end-point. Altogether 18.6% of the pages had as their subject matter clinically relevant trials. We compared the Journal Impact Factor (a measure of the number of citations per article in a journal) and the proportion of clinically relevant pages and found that they were inversely proportional to each other.
Electronic journal access: how does it affect the print subscription price?*
Chen, Frances L.; Wrynn, Paul; Rieke, Judith L.
2001-01-01
Objective: This study examined the rates of print journal subscription price increases according to the type of available electronic access. The types of access included: electronic priced separately from the print, combination print with “free online” access, and aggregated, defined here as electronic access purchased as part of a collection. The percentages of print price increases were compared to each other and to that for titles available only in print. The authors were not aware of prior objective research in this area. Methods: The authors analyzed the percentage print price increases of 300 journals over a five-year time period. The titles were grouped according to type of available electronic access. The median and mean percentage print price increases were calculated and plotted for all titles within each group. Results: Using both the median and the mean to look at the percentage print price increases over five years, it was obvious that print prices for journals with electronic access exceeded journals that did not offer an electronic option. Electronic priced separately averaged 3% to 5% higher than print only titles using both measures. Combination print with “free online” access had higher increases from 1996 to 1999, but, in 2000, their percentage increases were about the same as print only titles. The rate of price increases for aggregated titles consistently went down over the past five years. Journals with no electronic option showed the lowest percentage rates of print price increase. Conclusions: The authors' findings reveal that the increases of print prices for their sample of titles were higher if a type of electronic access was offered. According to the results of this study, aggregated collections currently represent the electronic option whose percentage price increase for print prices was lowest. However, the uneven fluctuations in rates of subscription prices revealed that the pricing of journals with electronic access is still evolving. More study is recommended to see if the trends observed in this study are sustained over a longer time period. PMID:11837258

Journal usage studies, which are useful for budget management and for evaluating collection performance relative to library use, have generally described a single library or subject discipline. The Southern Chapter/Medical Library Association (SC/MLA) study has examined journal usage at the aggregate data level with the long-term goal of developing hospital library benchmarks for journal use. Thirty-six SC/MLA hospital libraries, categorized for the study by size as small, medium, or large, reported current journal title use centrally for a one-year period following standardized data collection procedures. Institutional and aggregate data were analyzed for the average annual frequency of use, average costs per use and non-use, and average percent of non-used titles. Permutation F-type tests were used to measure difference among the three hospital groups. Averages were reported for each data set analysis. Statistical tests indicated no significant differences between the hospital groups, suggesting that benchmarks can be derived applying to all types of hospital libraries. The unanticipated lack of commonality among heavily used titles pointed to a need for uniquely tailored collections. Although the small sample size precluded definitive results, the study's findings constituted a baseline of data that can be compared against future studies.

To review and critically assess trends observed regarding the levels of evidence in published articles in orthopaedic traumatology literature. The Journal of Orthopaedic Trauma, Journal of Bone and Joint Surgery-American, and Clinical Orthopaedics and Related Research. All articles from the years 1998, 2003, 2008, and 2013 in The Journal of Orthopaedic Trauma (JOT) and orthopaedic trauma-related articles from The Journal of Bone and Joint Surgery-American (JBJS-A) and Clinical Orthopaedics and Related Research (CORR) were analyzed. Articles were categorized by type and ranked for level of evidence according to guidelines from the Centre for Evidence-Based Medicine. Study type and standardized level of evidence were determined for each article. Articles were subcategorized as high-level evidence (I, II), moderate-level evidence (III), and low-level evidence (IV, V). During the study period, Journal of Bone and Joint Surgery-American reduced its low-level studies from 80% to 40% (P = 0.00015), Clinical Orthopaedics and Related Research decreased its low-level studies from 70% to 27%, and Journal of Orthopaedic Trauma decreased its low-level studies from 78% to 45%. Level IV and V therapeutic, prognostic, and diagnostic studies demonstrated significant decreases during the study period (P = 0.0046, P < 0.0001, P = 0.026). The percentage of high-level studies increased from 13% to 19%; however, this was not significant (P = 0.42). There was a trend showing an increase in level I and II studies for therapeutic, prognostic, and diagnostic studies (P = 0.06). There has been a statistically significant decrease in lower level of evidence studies published in the orthopaedic traumatology literature over the past 15 years.

This study examined the effect of an online guided independent study on critical reasoning skills. Twenty-one first-semester Master of Occupational Therapy students completed an online assignment designed to facilitate application of the Occupational Performance Process Model (Fearing & Clark) and kept reflective journals. Data from the journals were analyzed in relation to the three sets of questions, question type and results of the Watson-Glaser Critical Thinking Appraisal (WGCTA). This assignment appeared to be effective for enhancing awareness and use of critical reasoning skills. Differences in patterns of critical reasoning between students with high and low WGCTA scores and results of an inductive analysis of the journal entries are discussed. Future research investigating the types of feedback that effectively facilitate development of critical reasoning and whether students with high and low WGCTA scores might benefit from different types of instruction and/or feedback is recommended.

Parametric studies on floating pad journal bearing for high speed cryogenic turboexpanders
NASA Astrophysics Data System (ADS)
Jain, A.; Jadhav, M. M.; Karimulla, S.; Chakravarty, A.
2017-12-01
Most modern medium and large capacity helium liquefaction/refrigeration plants employ high speed cryogenic turboexpanders in their refrigeration/liquefaction cycles as active cooling devices. The operating speed of these turboexpanders is in the range of 3000-5000 Hz and hence specialized types of bearings are required. Floating pad journal bearing, which is a special type of tilting pad journal bearing, where mechanical pivots are absent and pads are fully suspended in gas, can be a good solution for stable operation of these high speed compact rotors. The pads are separated from shaft as well as from housing by fluid film between them, and both these sides of pad are interconnected by a network of feed holes. The work presented in this article aims to characterize floating pad journal bearings through parametric studies. The steady state performance characteristics of the bearing are represented by load capacity, stiffness coefficients and heat generation rate of the bearing. The geometrical parameters such as bearing clearances, preload of pads, etc. are varied and performance characteristics of the floating pad journal bearing are studied and presented. The dependence of stiffness coefficients on rotational speed of shaft is also analyzed.

The importance of systematic reviews (SRs) as an aid to decision making in health care has led to an increasing interest in the development of this type of study. When selecting a target journal for publication, authors generally seek out higher impact factor journals. This study aimed to determine the percentage of scientific medical journals that publish SRs according to their impact factors (>2.63) and to determine whether those journals require tools that aim to improve SR reporting and meta-analyses. In our cross-sectional study showing how to choose the right journal for a SR, we selected and analysed scientific journals available in a digital library with a minimum Institute for Scientific Information impact factor of 2.63. We analysed 622 scientific journals, 435 (69.94%) of which publish SRs. Of those 435 journals, 135 (21.60%) provide instructions for authors that mention SRs. Three hundred journals (48.34%) do not discuss criteria for article acceptance in the instructions for authors section, but do publish SRs. Only 118 (27.00%) scientific journals require items to be reported in accordance with the specific SR reporting forms. The majority of the journals do not mention the acceptance of SRs in the instructions for authors section. Only a few journals require that SRs meet specific reporting guidelines, making interpretation of their findings across studies challenging. There is no correlation between the impact factor of the journal and its acceptance of SRs for publication. © 2014 John Wiley & Sons, Ltd.

The aims of this study were to (a) describe the information provided in author guidelines in nursing journals, (b) assess the completeness of this information, and (c) identify the extent and types of reporting guidelines used in nursing journals. Content analysis of author guidelines for 245 nursing journals included in the Directory of Nursing Journals maintained at the International Academy of Nursing Editors website. Using Research Electronic Data Capture, data on 19 criteria for completeness were extracted from published author guidelines. Additional details about journal requirements, such as allowed length of manuscripts and format for the abstract, were also recorded. Reliability was established by simultaneous review of 25 journals (10%) by the research assistant and a senior member of the research team. Author guidelines were easily accessible at journal websites or through links to download the information. A majority (73.5%) had completeness scores of 75% or higher; six journals had guidelines that were 100% complete. Half of the journals used the American Psychological Association reference style, and 26.3% used the American Medical Association style. Less than one fourth had stated requirements to use reporting guidelines such as Consolidated Standards of Reporting Trials (CONSORT) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Author guidelines for nursing journals are generally complete and informative. Although specific reporting guidelines such as CONSORT and PRISMA improve the accuracy and completeness of manuscripts on various types of studies, most nursing journals do not indicate use of these for manuscript preparation. Editors who want to improve their author guidelines should use the 19 criteria for completeness as a gauge for updating and revision. Nurses rely on the published literature to inform their practice and ensure that it is based on evidence. Guidelines for publishing in the scholarly literature assist clinicians and scholars to ensure that published articles are complete, current, concise, and accurate. © 2018 The Authors.

The quiet revolution: reporting of health outcomes in general medical journals.
Seymour, J; Newell, D; Shiell, A
1997-01-01
This study reviews the extent of evaluation of health outcomes in three general medical journals over the past decade by examining papers published in the original research section of the New England Journal of Medicine (NEJM), The Lancet, and the Medical Journal of Australia (MJA) in 1982 and 1992. Evaluations were identified and classified according to the type of comparison group and the type of outcome measures employed. They were divided into three categories: those employing a comparison group; those employing a before-and-after study design (or own comparison group); and those with no comparison group. The categories of outcome measures were mortality, clinical or intermediate measures of health state, and final outcome measures (quality of life). Results show that the proportion of papers evaluating a health services intervention remained stable over the period. However, the MJA published considerably fewer evaluations than the other journals. In the NEJM and The Lancet, 75 per cent of evaluations incorporated comparison groups, in the MJA, less than 40 per cent. Overall, the proportion of papers reporting final outcome measures increased significantly between 1982 and 1992 (p = 0.04) but the change in each journal individually did not reach statistical significance. This study indicates that the reporting of health outcomes evaluations has remained constant but there has been some change in the use of comparison groups and final outcome measures over time.

Purpose: To begin investigating the impact of electronic journals on research processes such as information seeking, the authors conducted a pilot journal-use study to test the hypothesis that patrons use print and electronic journals differently. Methodology: We placed fifteen high-use print titles also available in electronic format behind the circulation desk; patrons were asked to complete a survey upon requesting a journal. We also conducted a parallel survey of patrons using library computers. Both surveys asked patrons to identify themselves by user category and queried them about their journal use. Results: During the month-long study, patrons completed sixty-nine surveys of electronic and ninety surveys of print journal use. Results analysis indicated that fellows, students, and residents preferred electronic journals, and faculty preferred print journals. Patrons used print journals for reading articles and scanning contents; they employed electronic journals for printing articles and checking references. Users considered electronic journals easier to access and search than print journals; however, they reported that print journals had higher quality text and figures. Discussion/Conclusion: This study is an introductory step in examining how electronic journals affect research processes. Our data revealed that there were distinct preferences in format among categories. In addition to collection management implications for libraries, these data also have implications for publishers and educators; current electronic formats do not facilitate all types of uses and thus may be changing learning patterns as well.

Mapping the literature of nursing informatics.
Guenther, Johanna T
2006-04-01
This study was part of the Medical Library Association's Nursing and Allied Health Resources Section's project to map the nursing literature. It identified core journals in nursing informatics and the journals referenced in them and analyzed coverage of those journals in selected indexes. Five core journals were chosen and analyzed for 1996, 1997, and 1998. The references in the core journal articles were examined for type and number of formats cited during the selected time period. Bradford's Law of Scattering divided the journals into frequency zones. The time interval, 1990 to 1998, produced 71% of the references. Internet references could not be tracked by date before 1990. Twelve journals were the most productive, 119 journals were somewhat productive, and 897 journals were the least productive. Journal of the American Medical Informatics Association was the most prolific core journal. The 1998 journal references were compared in CINAHL, PubMed/MEDLINE, Science Citation Index, and OCLC Article First. PubMed/MEDLINE had the highest indexing score.

Objective To examine changes in representation of women among first authors of original research published in high impact general medical journals from 1994 to 2014 and investigate differences between journals. Design Observational study. Study sample All original research articles published in Annals of Internal Medicine, Archives of Internal Medicine, The BMJ, JAMA, The Lancet, and the New England Journal of Medicine (NEJM) for one issue every alternate month from February 1994 to June 2014. Main exposures Time and journal of publication. Main outcome measures Prevalence of female first authorship and its adjusted association with time of publication and journal, assessed using a multivariable logistic regression model that accounted for number of authors, study type and specialty/topic, continent where the study was conducted, and the interactions between journal and time of publication, study type, and continent. Estimates from this model were used to calculate adjusted odds ratios against the mean across the six journals, with 95% confidence intervals and P values to describe the associations of interest. Results The gender of the first author was determined for 3758 of the 3860 articles considered; 1273 (34%) were women. After adjustment, female first authorship increased significantly from 27% in 1994 to 37% in 2014 (P<0.001). The NEJM seemed to follow a different pattern, with female first authorship decreasing; it also seemed to decline in recent years in The BMJ but started substantially higher (approximately 40%), and The BMJ had the highest total proportion of female first authors. Compared with the mean across all six journals, first authors were significantly less likely to be female in the NEJM (adjusted odds ratio 0.68, 95% confidence interval 0.53 to 0.89) and significantly more likely to be female in The BMJ (1.30, 1.01 to 1.66) over the study period. Conclusions The representation of women among first authors of original research in high impact general medical journals was significantly higher in 2014 than 20 years ago, but it has plateaued in recent years and has declined in some journals. These results, along with the significant differences seen between journals, suggest that underrepresentation of research by women in high impact journals is still an important concern. The underlying causes need to be investigated to help to identify practices and strategies to increase women’s influence on and contributions to the evidence that will determine future healthcare policies and standards of clinical practice.

The 100 most cited articles in dentistry.
Feijoo, Javier F; Limeres, Jacobo; Fernández-Varela, Marta; Ramos, Isabel; Diz, Pedro
2014-04-01
To identify the 100 most cited articles published in dental journals. A search was performed on the Institute for Scientific Information (ISI) Web of Science for the most cited articles in all the journals included in the Journal Citation Report (2010 edition) in the category of "Dentistry, Oral Surgery, and Medicine". Each one of the 77 journals selected was analyzed using the Cited Reference Search tool of the ISI Web of Science database to identify the most cited articles up to June 2012. The following information was gathered from each article: names and number of authors, journal, year of publication, type of study, methodological design, and area of research. The number of citations of the 100 selected articles varied from 326 to 2050. All articles were published in 21 of the 77 journals in the category. The journals with the largest number of the cited articles were the Journal of Clinical Periodontology (20 articles), the Journal of Periodontology (18 articles), and the Journal of Dental Research (16 articles). There was a predominance of clinical research (66 %) over basic research (34 %). The most frequently named author was Socransky SS, with 9 of the top 100 articles, followed by Lindhe J with 7. The decades with most articles published of the 100 selected were 1980-1989 (26 articles) and 1990-1999 (25 articles). The most common type of article was the case series (22 %), followed by the narrative review/expert opinion (19 %). The most common area of study was periodontology (43 % of articles). To our knowledge, this is the first report of the top-cited articles in Dentistry. There is a predominance of clinical studies, particularly case series and narrative reviews/expert opinions, despite their low-evidence level. The focus of the articles has mainly been on periodontology and implantology, and the majority has been published in the highest impact factor dental journals. The number of citations that an article receives does not necessarily reflect the quality of the research, but the present study gives some clues to the topics and authors contributing to major advances in Dentistry.

The burden of traumatic and elective hip surgery is set to grow. With an increasing number of techniques and implants against the background of an aging population, the emphasis on evidence-based treatment has never been greater. The purpose of this study was to assess changes in the levels of evidence in the hip literature over a decade. Articles pertaining to hip surgery from the years 2000 and 2010 in Hip International, Journal of Arthroplasty, Journal of Bone and Joint Surgery and The Bone and Joint Journal were analysed. Articles were ranked by a five-point level of evidence scale and by type of study, according to guidelines from the Centre for Evidence-based Medicine. 531 articles were analysed from 48 countries. The kappa value for the inter-observer reliability showed excellent agreement between the reviewers for study type (κ = 0.956, P < 0.01) and for levels of evidence (κ = 0.772, P < 0.01). Between 2000 and 2010, the overall percentage of high-level evidence (levels I and II) studies more than doubled (12 to 31 %, P < 0.001). The most frequent study type was therapeutic; the USA and UK were the largest producers of published work in these journals, with contributions from other countries increasing markedly over the decade. There has been a significant increase in high levels of evidence in hip surgery over a decade (P < 0.001). We recommend that all orthopaedic journals consider implementing compulsory declaration by authors of the level of evidence to help enhance quality of evidence. Level 2: economic and decision analysis.

Public health journals need to have clear policies for reporting the funding of studies and authors' personal financial and non-financial conflicts of interest (COI) disclosures. This study aims to assess the policies of public health journals on reporting of study funding and the disclosure of authors' COIs. This is a cross-sectional study of "Public, Environmental & Occupational Health" journals. Teams of two researchers abstracted data in duplicate and independently using REDCap software. Of 173 public health journals, 155 (90%) had a policy for reporting study funding information. Out of these, a majority did not require reporting of the phase of the study for which funding was received (88%), nor the types of funding sources (87%). Of the 173 journals, 163 (94%) had a policy requiring disclosure of authors' COI. However, the majority of these journals did not require financial conflicts of interest disclosures relating to institutions (75%) nor to the author's family members (90%) while 56% required the disclosure of at least one form of non-financial COI. The policies of the majority of public health journals do not require the reporting of important details such as the role of the funder, and non-financial COI. Journals and publishers should consider revising their editorial policies to ensure complete and transparent reporting of funding and COI.
Content and bibliometric analyses of the Journal of Manual & Manipulative Therapy
Simon, Corey B; Coronado, Rogelio A; Wurtzel, Wendy A; Riddle, Daniel L; George, Steven Z
2014-01-01
Background: Article characteristics and trends have been elucidated for other physical therapy-focused journals using content and bibliometric analysis. These findings are important for assessing the current state of a journal and for guiding future publication of research. To date, these analyses have not been performed for the Journal of Manual & Manipulative Therapy (JMMT). Objective: To describe content and trends for articles published in JMMT over a 20-year period (1993–2012). Methods: Journal articles were coded using previously-established domains (article type, participant type, research design, study purpose, and clinical condition). Total publications and proportion of publications based on domain were described. Articles specific to manual therapy intervention were examined and compared to data from other physical therapy-focused journals. Impact by citation and author was examined using bibliometric software. Results: Journal of Manual & Manipulative Therapy was found to have a recent acceleration in the number of articles published annually. Over time, topical reviews have decreased in favor of research reports. However, rigorous study designs have represented only a small portion of total journal content, and case reports have maintained a consistent publication presence. Manual therapy intervention articles in JMMT are predominantly case designs, however are similar in characteristics to manual therapy intervention articles published in other physical therapy-focused journals. For JMMT articles overall and manual therapy intervention articles across journals, young to middle-aged symptomatic adults with low back and/or neck pain were the most common study participants. Discussion: Increases in the number of papers and a move toward research reports were observed in JMMT over the 20-year period. Considerations for the future were outlined, including the publication of articles with more rigorous research designs. Manual therapy research for adolescents and older adults and for upper and lower extremity conditions should also be considered as priorities for the future. PMID:25395826

Abstract Purpose The aims of this study were to (a) describe the information provided in author guidelines in nursing journals, (b) assess the completeness of this information, and (c) identify the extent and types of reporting guidelines used in nursing journals. Design Content analysis of author guidelines for 245 nursing journals included in the Directory of Nursing Journals maintained at the International Academy of Nursing Editors website. Methods Using Research Electronic Data Capture, data on 19 criteria for completeness were extracted from published author guidelines. Additional details about journal requirements, such as allowed length of manuscripts and format for the abstract, were also recorded. Reliability was established by simultaneous review of 25 journals (10%) by the research assistant and a senior member of the research team. Findings Author guidelines were easily accessible at journal websites or through links to download the information. A majority (73.5%) had completeness scores of 75% or higher; six journals had guidelines that were 100% complete. Half of the journals used the American Psychological Association reference style, and 26.3% used the American Medical Association style. Less than one fourth had stated requirements to use reporting guidelines such as Consolidated Standards of Reporting Trials (CONSORT) and Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA). Conclusions Author guidelines for nursing journals are generally complete and informative. Although specific reporting guidelines such as CONSORT and PRISMA improve the accuracy and completeness of manuscripts on various types of studies, most nursing journals do not indicate use of these for manuscript preparation. Editors who want to improve their author guidelines should use the 19 criteria for completeness as a gauge for updating and revision. Clinical Relevance Nurses rely on the published literature to inform their practice and ensure that it is based on evidence. Guidelines for publishing in the scholarly literature assist clinicians and scholars to ensure that published articles are complete, current, concise, and accurate. PMID:29645403

This paper defines and discusses two important types of citations, self-citation and mandatory citation, in engineering journals. Citation can be classified in three categories: optional; semi-mandatory; and mandatory. There are some negative and positive impacts for the authors' paper and journals' reputation if mandatory citation of a paper or set of papers is requested. These effects can be different based on the recommended papers for citing in the new research. Mandatory citation has various types discussed in this paper. Self-citation and its reasons and impacts are also discussed in the present study.

Author disclosure of conflict of interest in vascular surgery journals.
Forbes, Thomas L
2011-09-01
Advances in vascular surgery are increasingly technology-driven, and the relationships between surgeons and the medical device industry can be complex. This study reviewed conflict of interest (COI) disclosure in the vascular surgery journals regarding several selected technology-driven topics, including endovascular stent grafts (EV), carotid artery stenting (CAS), and peripheral arterial interventions (PI), to suggest further directions. Authors' COI disclosures were reviewed from all clinical papers published in 2008 and 2009 in each of six vascular surgery journals, and pertaining to three selected topics (EV, CAS, and PI). Rate of COI disclosure was evaluated as a function of journal, topic, article type (randomized trial, case series, case report, review, or meta-analysis), and authors' region of origin. Secondarily, consistency of authors' disclosure was evaluated by reviewing papers by the same author and of the same topic. Six hundred thirty-five papers were reviewed from the six journals. A COI was declared in 125 (19.7%) of these papers. This rate differed between journals (range, 3.2%-34.1%; P < .0001). Rate of disclosure did not differ between topics (range, 12.8%-21.2%; P = .12), article type (range, 14.7%-30%; P = .28), or region of origin (range, 0%-33.3%; P = .09). There were 116 instances of the same author writing papers describing the same general topic. COI disclosure was consistent in the majority of these instances (72.4%), but inconsistent in 32 cases (27.6%). The most common (P = .006) inconsistencies involved the same type of article in different journals (46.9%), or in the same journal (25%). Rates of disclosure of COI, and inconsistencies in disclosure in the vascular surgery literature are at least partially due to differences in journals' reporting policies, while a smaller proportion of these inconsistencies are due to individual author behavior. Journals should adopt a consistent requirement for a separate COI declaration where all relevant financial arrangements are disclosed. Copyright © 2011 Society for Vascular Surgery.

Full length articles published in BJOMS during 2010-11--an analysis by sub-specialty and study type.
Arakeri, Gururaj; Colbert, Serryth; Rosenbaum, Gavin; Brennan, Peter A
2012-12-01
Full length articles such as prospective and retrospective studies, case series, laboratory-based research and reviews form the majority of papers published in the British Journal of Oral and Maxillofacial Surgery (BJOMS). We were interested to evaluate the breakdown of these types of articles both by sub-specialty and the type of study as well as the proportion that are written by UK colleagues compared to overseas authors over a 2 year period (2010-11). A total of 191 full length articles across all sub-specialties of our discipline were published, with 107 papers (56%) coming from UK authors. There were proportionately more oncology papers arising from the UK than overseas (60 and 30% of total respectively) while the opposite was found for cleft/deformity studies (10% and 22%). There was only one laboratory-based study published from the UK compared with 27 papers from overseas. The number of quality papers being submitted to the Journal continues to increase, and the type of article being published between UK and overseas probably reflects different practices and case-loads amongst colleagues. The relatively few UK laboratory based studies published in BJOMS compared to overseas authors are most likely due to authors seeking the most prestigious journals possible for their work.

To audit the number and type of published articles related to medical education in leading Pakistani biomedical journals. The audit covered the period from January 2001 to December 2013. Journals either indexed in Medline or having an impact factor were selected. The audit was done in two phases. First, articles related to medical education were screened by reading the titles. Then abstracts were studied and articles were placed into several pre-defined categories based on article type and research topic. Data was analysed using SPSS 20. A total of 118 relevant articles were published. Of them, 60(51%) articles were published in the Journal of Pakistan Medical Association, 42(35.6%) in the Journal of College of Physicians and Surgeons Pakistan, 4(3.4%) in Pakistan Journal of Medical Sciences, and 12(10.2%) in the Journal of Ayub Medical College. Articles related to curriculum development were 33(28.0 %), teaching 28(23.7%), assessment 29(24.6%), faculty training 5(4.2%), continuous medical education 4(3.4%), ethics 3(2.5%), and others 16(13.6%). There is a need to increase the quality of health profession education research, documentation and audit of the global contribution of Pakistani medical educationists.

To identify the 100 top-cited articles published in orthodontics journals and to analyze their characteristics to investigate the achievement and development of orthodontics research in past decades. The Institute for Scientific Information Web of Knowledge Database and the 2011 Journal Citation Report Science Editions were used to retrieve the 100 top-cited articles published in orthodontics journals since 1975. Some basic information was collected by the Analyze Tool on the Web of Science, including citation time, publication title, journal name, publication year, and country and institution of origin. A further study was then performed to determine authorship, article type, field of study, study design, and level of evidence. The 100 target articles were retrieved from three journals: American Journal of Orthodontics and Dentofacial Orthopedics (n = 74), The Angle Orthodontist (n = 15), and European Journal of Orthodontics (n = 11). Since 1975, the articles cited 89 to 545 times mainly originated from the United States, and the overwhelming majority of articles were clinical. The most common study design was case series; 40 articles were classified as level IV and 12 as level V evidence. The 100 top-cited articles in orthodontics are generally old articles, rarely possessing high-level evidence.

To identify 100 top-cited articles published in periodontal journals and analyse the research trends by using citation analysis. 100 top-cited articles published in periodontal journals were retrieved by searching the database of the ISI Web of Science and Journal Citation reports. For each article, the following principal bibliometric parameters: authorship, geographic and institute origin, manuscript type, study design, scope of study, and citation count of each time period were analysed from 1965 to 2015. The identified 100 top-cited articles were retrieved from five periodontal journals and citation counts were recorded between 262 and 1,693 times. For the institute of origin, the most productive institute, in terms of the number of 100 top-cited articles published, was the University of Gothenburg (Sweden) (n = 19), followed by the Forsyth Dental Center (USA) (n = 15). Most manuscripts were original research (n = 74), and the inflammatory periodontal disease (n = 59) was the most frequent topic studied. Interestingly, the trend of increase average citation reached significance for implantology (β = 26.75, P = 0.003) and systemic interactions (β = 29.83, P = 0.005), but not for inflammatory disease (β = -10.30, P = 0.248) and tissue regeneration (β = 9.04, P = 0.081). By using multivariable linear regression in a generalised linear model, suitable published journal (Journal of Clinical Periodontology), geographic regions (Europe), more intense international collaboration, adequate manuscript type (review article) and study design (systematic review) could be attributed to escalating average citation counts in implantology (all P < 0.05). However, for systemic interactions, only geographic region and study design were significantly associated with the increasing citation trend. These principal bibliometric characteristics revealed escalated trends in average citation count in implantology throughout time. Conflict-of-interest statement The authors have stated explicitly that there are no conflicts of interest in connection with this article. The study was self-funded by the authors and their institution.

Using inaccurate quotations can propagate misleading information, which might affect the management of patients. The aim of this study was to determine the predictors of quotation inaccuracy in the peer-reviewed orthopaedic literature related to the scaphoid. We randomly selected 100 papers from ten orthopaedic journals. All references were retrieved in full text when available or otherwise excluded. Two observers independently rated all quotations from the selected papers by comparing the claims made by the authors with the data and expressed opinions of the reference source. A statistical analysis determined which article-related factors were predictors of quotation inaccuracy. The mean total inaccuracy rate of the 3840 verified quotes was 7.6%. There was no correlation between the rate of inaccuracy and the impact factor of the journal. Multivariable analysis identified the journal and the type of study (clinical, biomechanical, methodological, case report or review) as important predictors of the total quotation inaccuracy rate. We concluded that inaccurate quotations in the peer-reviewed orthopaedic literature related to the scaphoid were common and slightly more so for certain journals and certain study types. Authors, reviewers and editorial staff play an important role in reducing this inaccuracy.

The aims of this study were to evaluate the trends in funding, geographic origin, and study types of original articles in the dental implant literature and to investigate the relationships among these factors. Articles published in Clinical Oral Implants Research, The International Journal of Oral and Maxillofacial Implants, Clinical Implant Dentistry and Related Research, Implant Dentistry, and Journal of Oral Implantology from 2005 to 2009 were reviewed. Nonoriginal articles were excluded. For each article included, extramural funding source, geographic origin, and study type were recorded. Descriptive and analytic analyses (α = .05), including a logistic regression analysis, and chi-square test were used where appropriate. Of a total of 2,085 articles published, 1,503 met the inclusion criteria. The most common source of funding was from industry (32.4%). The proportion of studies that reported funding increased significantly over time. Europe represented the highest percentage (55.8%) of published articles. Most of the articles reported on clinical studies (49.9%), followed by animal studies (25.9%). Articles from Asia and South America and animal and in vitro studies were significantly more likely to be funded. Almost half of the original dental implant articles were funded. The trend toward internationalization of authorship was evident. A strong association was observed between funding and geographic origin and between funding and study type. Most studies in North America and Europe were clinical studies and supported by industry, whereas a greater proportion of studies in Asia and South America were in vitro or animal studies funded through government resources.

Although qualitative studies have increased since the 1990s, some reports note that relatively few influential journals published them up until 2000. This study critically reviewed the characteristics of qualitative studies published in top tier medical journals since 2000. We assessed full texts of qualitative studies published between 2000 and 2004 in the Annals of Internal Medicine, BMJ, JAMA, Lancet, and New England Journal of Medicine. We found 80 qualitative studies, of which 73 (91%) were published in BMJ. Only 10 studies (13%) combined qualitative and quantitative methods. Sixty-two studies (78%) used only one method of data collection. Interviews dominated the choice of data collection. The median sample size was 36 (range: 9-383). Thirty-three studies (41%) did not specify the type of analysis used but rather described the analytic process in detail. The rest indicated the mode of data analysis, in which the most prevalent methods were the constant comparative method (23%) and the grounded theory approach (22%). Qualitative data analysis software was used by 33 studies (41%). Among influential journals of general medicine, only BMJ consistently published an average of 15 qualitative study reports between 2000 and 2004. These findings lend insight into what qualities and characteristics make a qualitative study worthy of consideration to be published in an influential journal, primarily BMJ.
Influence of Article Type on the Impact Factor of Dermatology Journals.

For scientific journals, achieving a high impact factor (IF) has become a goal in its own right. Our aim was to describe the influence of article type on the IF of dermatology journals. We used the Scopus database to calculate an IF for Actas Dermo-Sifiliográficas and the major dermatology journals, excluding articles without abstracts, letters to the editor, and conference proceedings. Included articles were classified into 4 categories: case reports, original articles, narrative reviews, and other. We also calculated the mean IF for each article type. We then compared our results with IFs published by the Institute for Scientific Information. The proportion of each type of article differed between journals. Original articles carried the greatest weight in the major journals (BJD, 76.8%; Contact, 81.1%; JAAD, 63.4%; JAMA Dermatol, 63.7%.) but not in Actas Dermo-Sifiliográficas, where only 31.7% were original research articles. A higher IF was associated with the publication of reviews and original articles; a lower IF was associated with the publication of case reports and other article types. Publishing case reports, which have lower citation rates, leads to a lower IF. Publishing reviews and original articles will lead to a higher IF. Journals that seek a higher IF should probably publish more reviews and original articles and fewer case reports. Editorial boards should seek a balance between the interests of their clinician readers and the journal's need for a higher IF. Copyright © 2018 AEDV. Publicado por Elsevier España, S.L.U.

The aim of this study was to examine the publication characteristics and development of Journal of Advanced Nursing during its 40-year history. Bibliometric studies of single journals have been performed, but to the best of our knowledge, bibliometric analysis and bibliometric mapping have not yet been used to analyse the literature production of the Journal of Advanced Nursing. Using descriptive bibliometrics, we studied the dynamics and trend patterns of literature production and identified document types and the most prolific authors, papers, institutions and countries. Bibliometric mapping was used to visualize the content of published articles and determine the most prolific research terms and themes published in Journal of Advanced Nursing and their evolution through time. We were also interested in determining whether there were any 'Sleeping Beauties' among the articles published in the journal. The study revealed a positive trend in literature production, although recently, the number of articles published in Journal of Advanced Nursing has slightly decreased. The most productive institutions are from the United Kingdom, which ranks in the highest place in terms of successful publishing in the journal. Thematic analysis showed that the most prolific themes corresponded to the basic aims and scope of the journal. Journal of Advanced Nursing contributes to advances in nursing research, practice and education as well as the quality of health care, teamwork and family care, with an emphasis on knowledge transfer and partnership between various healthcare professionals. © 2017 John Wiley & Sons Ltd.

Poor research reporting is a major contributing factor to low study reproducibility, financial and animal waste. The ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines were developed to improve reporting quality and many journals support these guidelines. The influence of this support is unknown. We hypothesized that papers published in journals supporting the ARRIVE guidelines would show improved reporting compared with those in non-supporting journals. In a retrospective, observational cohort study, papers from 5 ARRIVE supporting (SUPP) and 2 non-supporting (nonSUPP) journals, published before (2009) and 5 years after (2015) the ARRIVE guidelines, were selected. Adherence to the ARRIVE checklist of 20 items was independently evaluated by two reviewers and items assessed as fully, partially or not reported. Mean percentages of items reported were compared between journal types and years with an unequal variance t-test. Individual items and sub-items were compared with a chi-square test. From an initial cohort of 956, 236 papers were included: 120 from 2009 (SUPP; n = 52, nonSUPP; n = 68), 116 from 2015 (SUPP; n = 61, nonSUPP; n = 55). The percentage of fully reported items was similar between journal types in 2009 (SUPP: 55.3 ± 11.5% [SD]; nonSUPP: 51.8 ± 9.0%; p = 0.07, 95% CI of mean difference -0.3-7.3%) and 2015 (SUPP: 60.5 ± 11.2%; nonSUPP; 60.2 ± 10.0%; p = 0.89, 95%CI -3.6-4.2%). The small increase in fully reported items between years was similar for both journal types (p = 0.09, 95% CI -0.5-4.3%). No paper fully reported 100% of items on the ARRIVE checklist and measures associated with bias were poorly reported. These results suggest that journal support for the ARRIVE guidelines has not resulted in a meaningful improvement in reporting quality, contributing to ongoing waste in animal research.

Evidence-based medicine has established itself in the field of gastroenterology. In this study we aim to assess the types of study designs of gastroenterology-related articles published in Saudi scientific journals. An online review using PubMed was carried out to review gastroenterology-related articles published in six Saudi medical journals in the time interval from 2003 to 2012. To classify the level of evidence in these articles we employed the Oxford's levels of evidence. One-way analysis of variance was used to compare the levels of evidence between published articles. A total of 721 gastroenterology-related articles were reviewed, of which 591 articles met our inclusion criteria; 80.7% were level IV. The three most common types of studies we encountered were cross-sectional (33.9%), case reports (27.9%), and case series (18.8%). Forty-three percent of the published research was in the field of hepatobiliary and spleen. The total number of articles increased from 260 articles in the 1 st 5-year period (2003-2007) to 330 in the 2 nd period (2008-2012). However, no statistically significant difference in the level of evidence was noted. In Annals of Saudi Medicine Journal, articles with level II increased from 0 to 10% with a P value 0.02. In our review of gastroenterology-related published articles in Saudi scientific journals, we observed an increase in the quantity of articles with the quality and level of evidence remaining unchanged. Further research is recommended to explore different reasons affecting the volume and quality of gastroenterology-related research in Saudi scientific journals.

The ability to identify scientific journals that publish high-quality research would help clinicians, scientists, and health-policy analysts to select the most up-to-date medical literature to review. To assess whether journal characteristics of (1) peer-review status, (2) citation rate, (3) impact factor, (4) circulation, (5) manuscript acceptance rate, (6) MEDLINE indexing, and (7) Brandon/Hill Library List indexing are predictors of methodological quality of research articles, we conducted a cross-sectional study of 243 original research articles involving human subjects published in general internal medical journals. The mean (SD) quality score of the 243 articles was 1.37 (0.22). All journals reported a peer-review process and were indexed on MEDLINE. In models that controlled for article type (randomized controlled trial [RCT] or non-RCT), journal citation rate was the most statistically significant predictor (0.051 increase per doubling; 95% confidence interval [CI], 0.037-0.065; P<.001). In separate analyses by article type, acceptance rate was the strongest predictor for RCT quality (-0.113 per doubling; 95% CI, -0.148 to -0.078; P<.001), while journal citation rate was the most predictive factor for non-RCT quality (0.051 per doubling; 95% CI, 0.044-0.059; P<.001). High citation rates, impact factors, and circulation rates, and low manuscript acceptance rates and indexing on Brandon/Hill Library List appear to be predictive of higher methodological quality scores for journal articles.

The aims of this study were as follows: 1) to determine publication rate, time to publication, and study design of poster presentations accepted at the National Congress of Child and Adolescent Psychiatry (NCCAP) and converted to publication and the degree of first author in a published article and journal index and 2) to investigate the relationship of these data with each other. The poster presentations of four congresses organized between 2005 and 2008 were investigated separately. The presentations were screened by taking into account the title and the first and second author in English and Turkish languages via PubMed and Google Academic databases. Published studies, time between presentation and publishing date, study design, degree of first author, and journal index of these studies were recorded. Fifty-four (25.2%) of 214 poster presentations were published in international and national peer-reviewed journals. Of the published articles, 74.1% (n=40) were research type and 61.1% (n=33) were found in the Science Citation Index (SCI) and Science Citation Index-Expanded (SCI-E) peer-reviewed journals. The first author in 42.6% (n=23) of published articles were assistant professors. The average time between presentation and publishing date was 30.72±18.89 months. Statistical differences were not determined between publication rate and study design; between time to publication and study type/study design, degree of first author, and journal index; and between journal index and study design and degree of first author (p>0.05). It was found that research articles were published significantly more by teaching staff than experts and other researchers (p<0.05). Compared with literature data, it was found that the time to publication was longer while the publication rate was similar for poster presentations in our congresses. Based on these results, it is important to create necessary conditions and encourage the researchers to publish the poster presentations presented in NCCAP.

Mapping the literature of home health nursing.
Friedman, Yelena
2006-04-01
The purpose of this study was to identify core journals in home health nursing and to determine how well these journals were covered by indexing and abstracting services. The study was part of the project for mapping the nursing literature of the Medical Library Association's Nursing and Allied Health Resource Section. A citation analysis of two core journals was done to determine distribution of references by format types and age of citations and dispersion of the literature, according to Bradford's Law of Scattering. The analysis of indexing coverage for Zone 1 and 2 was also provided. The study showed that 64.2% of citations came from journals, versus 22.9% from books and 12.9% from other publications. PubMed/ MEDLINE rated highest in average indexing coverage of Zone 1 and 2 journals, followed by CINAHL. PsycINFO, SocioAbstracts, and EBSCO Health Business FullTEXT showed practically no coverage for the home health nursing literature. As expected, journal articles were found to be the primary source for referencing and books, the secondary source. In regard to bibliographic control, no databases provided full coverage of the journals in the field of home health nursing. PubMed/MEDLINE and CINAHL gave better results in combination, because CINAHL tended to cover more nursing journals, while PubMed/MEDLINE did better with medical titles.

To compare Spanish nursing journals with 2 English-language standard journals, as well as Spanish journals in closely related disciplines, to identify possible quantitative and qualitative shortcomings in scientific documentation. We performed a descriptive, cross-sectional study of the references contained in 796 articles from 6 Spanish journals from 3 health disciplines (2000-2002) and 2 English-language nursing journals (2000-2001). The number of references, type of publication cited, and language of the document cited were compared in individual journals, and in journals grouped by discipline and according to language. Spanish-language nursing journals had the lowest mean number of references per article (X- = 16.20) when compared with psychology journals (X- = 31.24), medical journals (X- = 31.39) and international nursing journals (X- = 37.11). Among Spanish journals, citation of English-language publications was most frequent in medical journals (X- = 26.28) and least frequent in nursing journals (X- = 6.04). In contrast, citation of Spanish documents was most frequent in nursing journals (X- = 9.79) and least frequent in medical journals (X- = 4.43). Although scientific publication of Spanish nursing has improved, it is not comparable to publication of closely related disciplines and international nursing. The low citation of English documents clearly reveals the risk of scientific insularity.
Fifty most-cited articles in anterior cruciate ligament research.
Voleti, Pramod B; Tjoumakaris, Fotios P; Rotmil, Gayle; Freedman, Kevin B
2015-04-01
The number of times an article has been cited in the peer-reviewed literature is indicative of its impact on its respective medical specialty. No study has used citation analysis to determine the most influential studies pertaining to the anterior cruciate ligament (ACL). The primary aims of this study were to identify the classic works in ACL research using citation analysis and to characterize these articles to determine which types of studies have had the most influence on the field. A systematic query of ISI Web of Science (Thomson Reuters, Philadelphia, Pennsylvania) was performed for articles pertaining to the ACL, and the 50 most-cited articles were selected for evaluation. The following characteristics were determined for each article: number of citations, citation density, journal, publication year, country of origin, language, article type, article subtype, and level of evidence. The number of citations ranged from 219 to 1073 (mean, 326), and the citation densities ranged from 4.9 to 55.6 citations per year (mean, 18.2). All articles were published in 1 of 11 journals, with the most being published in The American Journal of Sports Medicine (46%) and The Journal of Bone and Joint Surgery American (30%). The most common decades of publication were the 1990s (34%), 1980s (28%), and 2000s (26%). The majority (68%) of articles originated from the United States, and all were written in English. By article type, 42% were basic science, and 58% were clinical. Of the clinical articles, 3% were Level I, 17% were Level II, 28% were Level III, and 52% were Level IV. The articles were heterogeneous with regard to article type, article subtype, and level of evidence and tended to have the following characteristics: high-impact journal of publication, recent publication year, US origin, English language, and low level of evidence. These works represent some of the most popular scientific contributions to ACL research. This list may aid residency and fellowship programs in the compilation of articles for trainee reading curriculums. Copyright 2015, SLACK Incorporated.

Recent controversies highlighting substandard peer review in Open Access (OA) and traditional (subscription) journals have increased the need for authors, funders, publishers, and institutions to assure quality of peer-review in academic journals. I propose that transparency of the peer-review process may be seen as an indicator of the quality of peer-review, and develop and validate a tool enabling different stakeholders to assess transparency of the peer-review process. Based on editorial guidelines and best practices, I developed a 14-item tool to rate transparency of the peer-review process on the basis of journals' websites. In Study 1, a random sample of 231 authors of papers in 92 subscription journals in different fields rated transparency of the journals that published their work. Authors' ratings of the transparency were positively associated with quality of the peer-review process but unrelated to journal's impact factors. In Study 2, 20 experts on OA publishing assessed the transparency of established (non-OA) journals, OA journals categorized as being published by potential predatory publishers, and journals from the Directory of Open Access Journals (DOAJ). Results show high reliability across items (α = .91) and sufficient reliability across raters. Ratings differentiated the three types of journals well. In Study 3, academic librarians rated a random sample of 140 DOAJ journals and another 54 journals that had received a hoax paper written by Bohannon to test peer-review quality. Journals with higher transparency ratings were less likely to accept the flawed paper and showed higher impact as measured by the h5 index from Google Scholar. The tool to assess transparency of the peer-review process at academic journals shows promising reliability and validity. The transparency of the peer-review process can be seen as an indicator of peer-review quality allowing the tool to be used to predict academic quality in new journals.
Mapping the literature of pediatric nursing: update and implications for library services
Watwood, Carol L.
2016-01-01
Objective The purpose of this study was to identify core journals and other types of literature cited in four major pediatric nursing journals and to characterize coverage of these resources in major bibliographic databases. The study was part of the “Mapping the Literature of Nursing Project” of the Medical Library Association's Nursing and Allied Health Resource Section. It updates a similar analysis published in 2006 and determines whether citation patterns have changed over time. Methods Cited references from articles published in 4 pediatric nursing journals between 2011 and 2013 were collected. Cited journal titles were ranked according to number of times cited and analyzed according to Bradford's Law of Scattering and the 80/20 rule to identify the most frequently cited journals. Five databases were surveyed to assess the coverage of the most-often-cited journals. The most frequently cited non-journal sources were also identified. Results Journals were the most frequently cited sources, followed by books, government documents, Internet resources, and miscellaneous resources. Most cited sources were cited within ten years of their publication, which was particularly true for government documents and Internet resources. Scopus had complete coverage of the most frequently cited journals, whereas PubMed had nearly complete coverage. Conclusions Compared with the 2006 study, the list of top-cited journals referenced by pediatric nursing researchers has remained relatively stable, but the number of cited journal titles has increased. Book citations have declined, and Internet and government document references have increased. These findings suggest that librarians should retain subscriptions to frequently cited journal titles, provide efficient document delivery of articles from infrequently used journals, de-emphasize but not eliminate books, and connect patrons with useful open-access Internet resources.

To find out features in literature demand by researchers in the field of andrology and to offer advice on literature utilization and journal management. Five andrology journals indexed by Science Citation Index Expanded (SCI-E) (Andrologia, Archives of Andrology, Asian Journal of Andrology, International Journal of Andrology, and Journal of Andrology) were included in the study. Original articles, editorials, reviews, corrections and letters from these journals were analyzed with bibliometric method for document loading, citations, information absorbing ability, and geographical coverage. The average number of references in each paper was 28.78. The main type of references was periodicals (94.32%), while books and other sources accounted for only 5.68%. Average Price index was 30.14%. The number of references in the first ranking 10 periodicals cited by the five journals made up 34.53% of the total references cited. Geographically, the five journals covered 6 continents with 42 countries or regions. Andrology journals have a wide coverage of literatures, which are related to reproductive medicine, urology, endocrinology and biochemistry. References in andrology journals are mainly periodicals and are relatively old. US, China and Japan lead the world in andrology researches for the number of papers published.

Biased negative studies not only reflect poor research effort but also have an impact on 'patient care' as they prevent further research with similar objectives, leading to potential research areas remaining unexplored. Hence, published 'negative studies' should be methodologically strong. All parameters that may help a reader to judge validity of results and conclusions should be reported in published negative studies. There is a paucity of data on reporting of statistical and methodological parameters in negative studies published in Indian Medical Journals. The present systematic review was designed with an aim to critically evaluate negative studies published in prominent Indian Medical Journals for reporting of statistical and methodological parameters. Systematic review. All negative studies published in 15 Science Citation Indexed (SCI) medical journals published from India were included in present study. Investigators involved in the study evaluated all negative studies for the reporting of various parameters. Primary endpoints were reporting of "power" and "confidence interval." Power was reported in 11.8% studies. Confidence interval was reported in 15.7% studies. Majority of parameters like sample size calculation (13.2%), type of sampling method (50.8%), name of statistical tests (49.1%), adjustment of multiple endpoints (1%), post hoc power calculation (2.1%) were reported poorly. Frequency of reporting was more in clinical trials as compared to other study designs and in journals having impact factor more than 1 as compared to journals having impact factor less than 1. Negative studies published in prominent Indian medical journals do not report statistical and methodological parameters adequately and this may create problems in the critical appraisal of findings reported in these journals by its readers.

The purpose of this study was to determine the proportion of paper (podium) presentations at the 2006-2010 Arthroscopy Association of North America (AANA) annual scientific meetings that were ultimately published in a peer-reviewed journal. Furthermore, we aimed to evaluate whether the level of evidence correlated with the publication rate of these presentations or the impact factor (IF) of the publishing journal. Paper presentations from the 2006-2010 AANA annual meetings were included for evaluation. Clinical studies were graded for quality using the level of evidence by 2 independent reviewers. A comprehensive strategy was used to search the databases PubMed, Medline, and Embase for publications in scientific journals that corresponded to the presentations and were published within 5 years of the presentation date. Three hundred twenty-eight presentations were evaluated. Overall, 179 peer-reviewed publications corresponding to particular meeting presentations were identified, for a 5-year publication rate of 55%. There was no correlation between the publication rate and the level of evidence (P = .836), the type of study (P = .628), or the joint of focus (P = .07) of the presentations. The mean IF of journals that published Level I studies (4.8 [standard error, 2.3]) was significantly higher than the mean IF of journals that published Level II, III, or IV studies (2.58 [standard error, 0.10]) (P = .017). Between 2006 and 2010, presentations of the highest level of evidence at AANA meetings were subsequently published at a similar rate to presentations of lower levels of evidence, albeit in journals with higher IFs. This study is an important initial evaluation of the ultimate clinical impact of AANA meeting presentations. The study type, joint of focus, and level of evidence of the presentations all had no correlation with the rate at which these presentations were ultimately published.

Financial, nonfinancial and editors' conflicts of interest in high-impact biomedical journals.
Bosch, Xavier; Pericas, Juan M; Hernández, Cristina; Doti, Pamela
2013-07-01
To assess financial, nonfinancial and editors' conflicts of interest (COI) disclosure policies among the most influential biomedical journals publishing original research. We conducted a cross-sectional study of 399 high-impact biomedical journals in 27 biomedical categories of the Journal Citation Reports (JCR) in December 2011. Information relevant to COI and requirements for disclosures that was publicly available on journal websites was collected. While financial COI disclosures were required by 358 (89.7%) and nonfinancial by 280 (70.2%) journals, 155 (38.8%) required editors' disclosures. Journals in the first decile of the JCR classification scored significantly higher than those in the second decile for all disclosure policies. Ninety (22.6%) journals were published by Elsevier and 59 (14.8%) by Wiley-Blackwell, with Elsevier scoring significantly better in financial disclosure policies (P = 0.022). Clinical journals scored significantly higher than basic journals for all disclosure policies. No differences were observed between open-access (n = 25) and nonopen-access (n = 374) journals for any type of disclosure. Somewhat incoherently, authors' disclosure statements were included in some published manuscript in 57.1% of journals without any COI disclosure policies. Authors' financial COI disclosures were required by about 90% of high-impact clinical and basic journals publishing original research. Unlike recent studies showing a significantly lower prevalence of nonfinancial compared with financial disclosures, the former were required by about 70% of journals, suggesting that editors are increasingly concerned about nonfinancial competing interests. Only 40% of journals required disclosure of editors' COI, in conflict with the recommendations of the most influential editors' associations. © 2013 Stichting European Society for Clinical Investigation Journal Foundation.

Background/Aims: Evidence-based medicine has established itself in the field of gastroenterology. In this study we aim to assess the types of study designs of gastroenterology-related articles published in Saudi scientific journals. Patients and Methods: An online review using PubMed was carried out to review gastroenterology-related articles published in six Saudi medical journals in the time interval from 2003 to 2012. To classify the level of evidence in these articles we employed the Oxford's levels of evidence. One-way analysis of variance was used to compare the levels of evidence between published articles. Results: A total of 721 gastroenterology-related articles were reviewed, of which 591 articles met our inclusion criteria; 80.7% were level IV. The three most common types of studies we encountered were cross-sectional (33.9%), case reports (27.9%), and case series (18.8%). Forty-three percent of the published research was in the field of hepatobiliary and spleen. The total number of articles increased from 260 articles in the 1st 5-year period (2003–2007) to 330 in the 2nd period (2008–2012). However, no statistically significant difference in the level of evidence was noted. In Annals of Saudi Medicine Journal, articles with level II increased from 0 to 10% with a P value 0.02. Conclusion: In our review of gastroenterology-related published articles in Saudi scientific journals, we observed an increase in the quantity of articles with the quality and level of evidence remaining unchanged. Further research is recommended to explore different reasons affecting the volume and quality of gastroenterology-related research in Saudi scientific journals. PMID:25843195

PURPOSE This study aims to evaluate the analysis and publication rates of abstracts presented at the Turkish National Radiology meetings in 2010–2012. METHODS Abstracts presented in the national radiology meetings of 2010, 2011, and 2012 were included in the study. The presentations were classified according to presentation type (oral or poster presentations), study type, study design, imaged organ or body systems, imaging modalities, time interval between the presentation and the publication date, and the journal in which the article was published. The conversion rate of presentations into full-text articles in peer-reviewed journals were surveyed through PubMed. The time from presentation in the meetings to publication was determined. The distribution of journals was also demonstrated. RESULTS The total number of presentations submitted in three national radiology meetings was 3,192. The publication rate was 11% for the 2010 meeting, 8.2% for the 2011 meeting, and 9.6% for the 2012 meeting. A total of 300 papers were published, with an average of 15 months (range, 0–42 months) between presentation and final publication. The first three refereed international journals with the most number of papers derived from these meetings were Diagnostic and Interventional Radiology, Clinical Imaging, and European Journal of Radiology. CONCLUSION The overall publication rate of scientific abstracts from Turkey was lower than those from overseas countries. Encouraging the authors to conduct higher-quality research would raise the publication rate as well as improve the quality and success of our scientific meetings. PMID:26133322

Purpose We aimed to investigate association between bibliometric parameters, reporting and methodological quality of vascular and endovascular surgery randomised controlled trials. Methods The most recent 75 and oldest 75 randomised controlled trials published in leading journals over a 10-year period were identified. The reporting quality was analysed using the CONSORT statement, and methodological quality with the Intercollegiate Guidelines Network checklist. We used exploratory univariate and multivariable linear regression analysis to investigate associations. Findings Bibliometric parameters such as type of journal, study design reported in title, number of pages; external funding, industry sponsoring and number of citations are associated with reporting quality. Moreover, parameters such as type of journal, subject area and study design reported in title are associated with methodological quality. Conclusions The bibliometric parameters of randomised controlled trials may be independent predictors for their reporting and methodological quality. Moreover, the reporting quality of randomised controlled trials is associated with their methodological quality and vice versa.

Mapping the literature of home health nursing
Friedman, Yelena
2006-01-01
Objectives: The purpose of this study was to identify core journals in home health nursing and to determine how well these journals were covered by indexing and abstracting services. The study was part of the project for mapping the nursing literature of the Medical Library Association's Nursing and Allied Health Resource Section. Methods: A citation analysis of two core journals was done to determine distribution of references by format types and age of citations and dispersion of the literature, according to Bradford's Law of Scattering. The analysis of indexing coverage for Zone 1 and 2 was also provided. Results: The study showed that 64.2% of citations came from journals, versus 22.9% from books and 12.9% from other publications. PubMed/ MEDLINE rated highest in average indexing coverage of Zone 1 and 2 journals, followed by CINAHL. PsycINFO, SocioAbstracts, and EBSCO Health Business FullTEXT showed practically no coverage for the home health nursing literature. Conclusion: As expected, journal articles were found to be the primary source for referencing and books, the secondary source. In regard to bibliographic control, no databases provided full coverage of the journals in the field of home health nursing. PubMed/MEDLINE and CINAHL gave better results in combination, because CINAHL tended to cover more nursing journals, while PubMed/MEDLINE did better with medical titles. PMID:16710463

Background Recent controversies highlighting substandard peer review in Open Access (OA) and traditional (subscription) journals have increased the need for authors, funders, publishers, and institutions to assure quality of peer-review in academic journals. I propose that transparency of the peer-review process may be seen as an indicator of the quality of peer-review, and develop and validate a tool enabling different stakeholders to assess transparency of the peer-review process. Methods and Findings Based on editorial guidelines and best practices, I developed a 14-item tool to rate transparency of the peer-review process on the basis of journals’ websites. In Study 1, a random sample of 231 authors of papers in 92 subscription journals in different fields rated transparency of the journals that published their work. Authors’ ratings of the transparency were positively associated with quality of the peer-review process but unrelated to journal’s impact factors. In Study 2, 20 experts on OA publishing assessed the transparency of established (non-OA) journals, OA journals categorized as being published by potential predatory publishers, and journals from the Directory of Open Access Journals (DOAJ). Results show high reliability across items (α = .91) and sufficient reliability across raters. Ratings differentiated the three types of journals well. In Study 3, academic librarians rated a random sample of 140 DOAJ journals and another 54 journals that had received a hoax paper written by Bohannon to test peer-review quality. Journals with higher transparency ratings were less likely to accept the flawed paper and showed higher impact as measured by the h5 index from Google Scholar. Conclusions The tool to assess transparency of the peer-review process at academic journals shows promising reliability and validity. The transparency of the peer-review process can be seen as an indicator of peer-review quality allowing the tool to be used to predict academic quality in new journals. PMID:26824759
Mapping the literature of cytotechnology

The major purpose of this study was to identify and assess indexing coverage of core journals in cytotechnology. It was part of a larger project sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association to map the literature of allied health. Three representative journals in cytotechnology were selected and subjected to citation analysis to determine what journals, other publication types, and years were cited and how often. Bradford's Law of Scattering was applied to the resulting list of cited journals to identify core titles in the discipline, and five indexes were searched to assess coverage of these core titles. Results indicated that the cytotechnology journal literature had a small core but wide dispersion: one third of the 21,021 journal citations appeared in only 3 titles; another third appeared in an additional 26 titles; the remaining third were scattered in 1,069 different titles. Science Citation Index Expanded rated highest in indexing coverage of the core titles, followed by MEDLINE, EMBASE/Excerpta Medica, HealthSTAR, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The study's results also showed that journals were the predominantly cited format and that citing authors relied strongly on more recent literature. PMID:10783973
A systematic appraisal of the Evidence-Based Dentistry Journal.
Mehta, Nikisha; Marshman, Zoe
2016-09-01
BackgroundThis systematic appraisal was conducted to determine if the Evidence-Based Dentistry Journal (EBDJ) acts as a reliable and contemporary source of knowledge for practitioners across all disciplines within dentistry.ObjectivesThe main objectives were to determine i) the year the articles were published and included in the EBDJ; ii) if the articles published covered all fields equally within dentistry; iii) the type of study design of the articles reported in the journal and; iv) the level of expertise of the writers of the commentaries.MethodsThis study used a systematic approach to assess the articles included in the journal. Data were extracted on the difference in the year the article was originally published and the year the article was included in the EBDJ, the number of articles in each dental discipline, the type of study designs included in the journal and the expertise of the commentators of each article. The information provided by the journal was validated by accessing the original articles through electronic databases.ResultsThe appraisal considered the 582 articles that met the inclusion criteria. Overall, 45.3% of the articles were included in the EBDJ in the same year and 44.8% of the articles were included a year after they were originally published. The number of articles varied across disciplines within dentistry: 23.7% from dental public health, 18.4% from periodontology and 11.8% from orthodontics, with only 4.6% from prosthodontics, 1% from oral pathology and 0.5% from dental materials. Most of the articles were systematic reviews and randomised controlled trials at 72% and 22.3% respectively. The writers of the commentaries were mostly academics and hospital consultants (71.2% and 13.6% commentators).ConclusionsOn the whole, it can be concluded that the journal acts as a reliable and contemporary source of knowledge/evidence for dentists, however, not all specialities within dentistry had equal coverage.

Gender and first authorship of papers in family medicine journals 2006--2008.
Schrager, Sarina; Bouwkamp, Carla; Mundt, Marlon
2011-03-01
Despite increasing numbers of women attending medical school and completing residencies, women continue to lag behind men in academic achievement. Other specialties have found that women publish fewer journal articles than men. While family medicine is becoming increasingly gender balanced, the aim of this study was to evaluate the gender balance of published material within family medicine journals. All original articles were reviewed in five family medicine journals published in the United States (Family Medicine, Journal of Family Practice, Journal of the American Board of Family Medicine, Annals of Family Medicine, and American Family Physician) between 2006-2008. The articles were categorized based on type of publication and gender of first author. The editorial boards of each of the journals were examined to determine gender breakdown. A total of 2,126 articles were included in the study. Females were first author on 712 (33.5%) of the articles, and males authored 1,414 (66.5%). There was no significant difference between years. More female authors wrote original research, and fewer wrote letters to the editor. Only Family Medicine had gender parity on its editorial board. Female authors wrote about a third of all original publications in family medicine journals between 2006-2009 even though they comprise 44% of the faculty. Further research can evaluate reasons for this gender disparity.
Misconduct Policies in High-Impact Biomedical Journals
Bosch, Xavier; Hernández, Cristina; Pericas, Juan M.; Doti, Pamela; Marušić, Ana
2012-01-01
Background It is not clear which research misconduct policies are adopted by biomedical journals. This study assessed the prevalence and content policies of the most influential biomedical journals on misconduct and procedures for handling and responding to allegations of misconduct. Methods We conducted a cross-sectional study of misconduct policies of 399 high-impact biomedical journals in 27 biomedical categories of the Journal Citation Reports in December 2011. Journal websites were reviewed for information relevant to misconduct policies. Results Of 399 journals, 140 (35.1%) provided explicit definitions of misconduct. Falsification was explicitly mentioned by 113 (28.3%) journals, fabrication by 104 (26.1%), plagiarism by 224 (56.1%), duplication by 242 (60.7%) and image manipulation by 154 (38.6%). Procedures for responding to misconduct were described in 179 (44.9%) websites, including retraction, (30.8%) and expression of concern (16.3%). Plagiarism-checking services were used by 112 (28.1%) journals. The prevalences of all types of misconduct policies were higher in journals that endorsed any policy from editors’ associations, Office of Research Integrity or professional societies compared to those that did not state adherence to these policy-producing bodies. Elsevier and Wiley-Blackwell had the most journals included (22.6% and 14.8%, respectively), with Wiley journals having greater a prevalence of misconduct definition and policies on falsification, fabrication and expression of concern and Elsevier of plagiarism-checking services. Conclusions Only a third of top-ranking peer-reviewed journals had publicly-available definitions of misconduct and less than a half described procedures for handling allegations of misconduct. As endorsement of international policies from policy-producing bodies was positively associated with implementation of policies and procedures, journals and their publishers should standardize their policies globally in order to increase public trust in the integrity of the published record in biomedicine.

The universe, ultimately, is to be described by quantum theory. Quantum aspects of all there is, including space and time, may not be significant for many purposes, but are crucial for some. And so a quantum description of cosmology is required for a complete and consistent worldview. At any rate, even if we were not directly interested in regimes where quantum cosmology plays a role, a complete physical description could not stop at a stage before the whole universe is reached. Quantum theory is essential in the microphysics of particles, atoms, molecules, solids, white dwarfs and neutron stars. Why should one expect this ladder of scales to end at a certain size? If regimes are sufficiently violent and energetic, quantum effects are non-negligible even on scales of the whole cosmos; this is realized at least once in the history of the universe: at the big bang where the classical theory of general relativity would make energy densities diverge.

The paper describes the information needs of a state public health agency, compares needs to its library's collection, and evaluates collection development policy accordingly. A citation analysis of journal articles authored by Minnesota Department of Health staff as well as official publications from 2002 to 2004 was conducted. Fifty-six publications fitting the criteria for inclusion in the study were identified using PubMed and library records. Information on each cited reference was recorded, including reference type, relative age of citation, and journal name, if applicable. The library's collection and collection development policies were analyzed in regard to the results. As expected, journals were the most heavily cited format: 63% (n = 897) of all citations were to journal articles. Most cited materials were between 2 and 5 years old. The 897 journal citations represented 265 different journals. The top 10 cited journals (4% of all titles) accounted for 36% (n = 320) of all citations; 62% (n = 320) of journals were cited only once. Of the total journals cited, the library subscribed to 70% (n = 627). Overall, no large gaps appeared in the RN Barr Library's journal collection. The analysis confirms that the library's collections budget for serials and books reflects the cited use of these materials.

To give an overview of the behaviour and scientific contributions of the Journal of Bone and Joint Surgery American (JBJS-A) and British Volume (JBJS-B). 480 original articles published in 2009 were identified through a combined comprehensive computer and manual library search. Articles were assigned to 11 orthopaedic categories and by country, type and specialty of the institution. Possible grants and citations were analysed. USA led all countries in published articles (36,87%), followed by UK (20,62%) and South Korea (5,83%). Most studies published were performed at academic institutions (65,83 %), only 4,16% at private practices. Almost half of the articles (46,24%) were published in three categories: hip (19.16%), knee (13.75%) and trauma (13.33%). In both journals 47.15% articles had at least one funding source. A review of articles published in major journals allows to show how research in orthopaedics is distributed worldwide. This study shows that a variety of different journals is neccessary to reflect the broad spectrum of orthopaedics in depth. Level of Evidence III, Retrospective Comparative Study.

2014-12-01
The rapid development of information and communication technology has replaced traditional books by electronic versions. Most print dermatology journals have been replaced with electronic journals (e-journals), which are readily used by clinicians and medical students. The objectives of this study were to determine whether e-readers are appropriate for reading dermatology journals, to conduct an attitude study of both medical personnel and students, and to find a way of improving e-book use in the field of dermatology. All articles in the Korean Journal of Dermatology published from January 2010 to December 2010 were utilized in this study. Dermatology house officers, student trainees in their fourth year of medical school, and interns at Korea University Medical Center participated in the study. After reading the articles with Kindle 2, their impressions and evaluations were recorded using a questionnaire with a 5-point Likert scale. The results demonstrated that gray-scale e-readers might not be suitable for reading dermatology journals, especially for case reports compared to the original articles. Only three of the thirty-one respondents preferred e-readers to printed papers. The most common suggestions from respondents to encourage usage of e-books in the field of dermatology were the introduction of a color display, followed by the use of a touch screen system, a cheaper price, and ready-to-print capabilities. In conclusion, our study demonstrated that current e-readers might not be suitable for reading dermatology journals. However, they may be utilized in selected situations according to the type and topic of the papers.

Use of standards in papers published in dental journals.
Bona, Alvaro Della; Bello, Yuri Dal; Sartoretto, Suelen C
2012-01-01
This study evaluated the use de standards in papers published in Brazilian and international dental journals. Papers published from January 2006 to December 2010 in the following journals were examined: Brazilian Dental Journal (BDJ), Brazilian Oral Research (BOR), Journal of Applied Oral Sciences (JAOS), Journal of Dental Research (JDR) and Dental Materials (DM). In addition to the title and type of study, issue, volume and year of publication, the following information was recorded from each paper: identification of any standard reported in the study; in case of no reported standard, indication if a standard could be used in the study. A total of 3,046 papers were examined, being 937 from DM, 936 from JDR, 489 from JAOS, 348 from BDJ, and 336 from BOR. Considering the papers that could use some standard, DM showed the highest percentage (24.9%) of reporting standards/paper, followed by JAOS (10.3%), BOR (10.1%), BDJ (6.3%) and JDR (2.4%), meaning for example that, from 936 papers examined from the JDR, 623 could use some standard but only 15 papers reported them. From all papers examined, 309 (10.1%) reported using some standard. The ISO standards were mostly reported (57.8%), followed by ASTM standards (23.7%) and 74 (18.5%) standards from other international organizations (e.g. ADA and CIE). Despite of the high impact factors of the selected dental journals, their published papers could use standards more often. This study should assist journal editors to encourage authors to consult and refer to available standards to support the scientific papers.
Author-based journal selection system that helps authors save time in article submission.
Ozturk, Onur; Ileri, Fatih
2018-01-01
Submission to journals takes a lot of time and format related submission requirements vary greatly from one journal to another. Lack of time and motivation in academia reduces scientific outputs and demotivates researchers. Author-based journal selection system (ABJSS) is a platform for pooling manuscripts conceived to minimize the time spent for manuscript submission and to increase scientific output. The system will provide two types of account: "Author" and "Journal Administrator". Each account type will have its own abilities and permissions. The ABJJS system is an ongoing project that will be designed in cooperation with IT experts and academicians and it will be presented to the scientific world as soon as it secures sufficient support.

This study compared the conceptual foci and methodological characteristics of research projects which tested the effects of nursing interventions, published in four general nursing research journals with predominantly North American, and two with predominantly European/International authorship and readership. Dimensions and variables of comparison included: nature of subjects, design issues, statistical methodology, statistical power, and types of interventions and outcomes. Although some differences emerged, the most striking and consistent finding was that there were no statistically significant differences (and thus similarities) in the content foci and methodological parameters of the intervention studies published in both groups of journals. We conclude that European/International and North American nursing intervention studies, as reported in major general nursing research journals, are highly similar in the parameters studied, yet in need of overall improvement. Certainly, there is no empirical support for the common (explicit or implicit) ethnocentric American bias that leadership in nursing intervention research resides with and in the United States of America.
Hematology journals do not sufficiently adhere to reporting guidelines: a systematic review.
Wayant, C; Smith, C; Sims, M; Vassar, M

Essentials Reporting guidelines and trial/review registration aim to limit bias in research. We systematically reviewed hematology journals to examine the use of these policies. Forty-eight percent of journals made no use of these policies. Improving the use of reporting guidelines will improve research for all stakeholders. Background Reporting guidelines and trial/review registration policies have been instituted in order to minimize bias and improve research practices. Objective The objective of this study was to investigate the policies of hematology journals concerning reporting guideline adoption and trial/review registration. Methods We performed a web-based data abstraction from the Instructions for Authors of 67 hematology journals catalogued in the Expanded Science Citation Index of the 2014 Journal Citation Reports to identify whether each journal required, recommended or made no mention of the following reporting guidelines: EQUATOR, ICMJE, CONSORT, MOOSE, QUOROM, PRISMA, STARD, STROBE, ARRIVE and CARE. We also extracted whether journals required or recommended trial or systematic review registration. We e-mailed editors three times to determine which types of studies their journal accepts. Results Forty-eight per cent (32/67) of hematology journals do not adhere to any reporting guidelines. For responding journals, the QUOROM statement, MOOSE, CARE and PROSPERO were the least often mentioned, whereas the ICMJE guidelines, CONSORT statement and general trial registration were most often mentioned. Discussion Reporting guidelines are infrequently required or recommended by hematology journals. Furthermore, few require clinical trial or systematic review database registration. A higher rate of adherence to reporting guidelines can prevent bias from entering the literature. Participation from all stakeholders, including authors and journal editors, to improve reporting guideline and policy practices is required. © 2017 International Society on Thrombosis and Haemostasis.

The purpose of this study was to identify predatory journals in nursing, describe their characteristics and editorial standards, and document experiences of authors, peer reviewers, and editors affiliated with these journals. Using two sources that list predatory journals, the research team created a list of nursing journals. In Phase One, the team collected data on characteristics of predatory nursing journals such as types of articles published, article processing charge, and peer review process. In Phase Two, the team surveyed a sample of authors, reviewers, and editors to learn more about their experiences with their affiliated journals. Data from the review of predatory nursing journals were analyzed using descriptive statistics. Written comments were summarized and categorized. There were 140 predatory nursing journals from 75 publishers. Most journals were new, having been inaugurated in the past 1 to 2 years. One important finding was that many journals only published one or two volumes and then either ceased publishing or published fewer issues and articles after the first volume. Journal content varied widely, and some journals published content from dentistry and medicine, as well as nursing. Qualitative findings from the surveys confirmed previously published anecdotal evidence, including authors selecting journals based on spam emails and inability to halt publication of a manuscript, despite authors' requests to do so. Predatory journals exist in nursing and bring with them many of the "red flags" that have been noted in the literature, including lack of transparency about editorial processes and misleading information promoted on websites. The number of journals is high enough to warrant concern in the discipline about erosion of our scholarly literature. Nurses rely on the published literature to provide evidence for high-quality, safe care that promotes optimal patient outcomes. Research published in journals that do not adhere to the highest standards of publishing excellence have the potential to compromise nursing scholarship and is an area of concern. © 2016 Sigma Theta Tau International.

Objective The analysis of scientific production in Puerto Rico is largely unexplored. The main aim of this study is to present the characteristics and trends of cancer publications in Puerto Rico’s biomedical journals and their relationship with the island’s cancer mortality. Methods A PubMed and a hard-copy search were performed to retrieve cancer-related articles published in the Puerto Rico Health Sciences Journal and the Boletín de la Asociación Médica de Puerto Rico from 1903 to 2005. Bibliometric indicators studied included the number of authors and references by article, first author’s institutional affiliation and country, document type, and language. The study type and tumor classification were also recorded. Cancer proportional mortality (M%) in Puerto Rico and the proportion of cancer-related articles (P%) published were also evaluated. The annual percent change (APC) was estimated to assess trends. Results A total of 369 articles were retrieved. The institutions with the majority of publications were universities (39.6%), English was the predominant publication language (72.1%), and the principal document type was original papers (69.6%). Epidemiologic studies were the dominant study type (62.1%), and the most studied cancers were digestive (15.4%) and gynecologic (9.6%). Although the P% has increased since 1913 (APC = 1.2%), the M% increased at a faster pace (APC = 2.7%). Conclusions Although a growth in the number of cancer publications is observed in these journals, it does not parallel the increase in proportional mortality. A better understanding of the cancer publications in Puerto Rico is essential to establish priorities, define future areas of research, and develop cancer control strategies. PMID:19531324

Mapping selected general literature of international nursing.
Shams, Marie-Lise Antoun; Dixon, Lana S
2007-01-01
This study, part of a wider project to map the literature of nursing, identifies core journals cited in non-US nursing journals and determines the extent of their coverage by indexing services. Four general English-language journals were analyzed for format types and publication dates. Core titles were identified and nine bibliographic databases were scanned for indexing coverage. Findings show that 57.5% (13,391/23,271) of the cited references from the 4 core journals were to journal articles, 27.8% (6,471/23,271) to books, 9.5% (2,208/23,271) to government documents, 4.9% (1,131/23,271) to miscellaneous sources, and less than 1% (70/23,271) to Internet resources. Eleven journals produced one-third of the citations; the next third included 146 journals, followed by a dispersion of 1,622 titles. PubMed received the best database coverage scores, followed by CINAHL and Science Citation Index. None of the databases provided complete coverage of all 11 core titles. The four source journals contain a diverse group of cited references. The currency of citations to government documents makes these journals a good source for regulatory and legislative awareness. Nurses consult nursing and biomedical journals and must search both nursing and biomedical databases to cover the literature.

The number of citations an article receives after its publication reflects its impact in the scientific community. The aim of this study was to identify and characterize the 100 top-cited articles published in radiology journals. The top-cited articles published in 12 radiology journals were identified using the database of Science Citation Index Expanded (1945-2012). The 100 top-cited articles were selected and analyzed with regard to the number of citations, year of publication, publishing journal, authorship, institution and country of origin, type of article, radiologic subspecialty, main topic, and radiologic technique. The 100 top-cited articles were published in eight radiology journals, led by Radiology (n=67) and followed by the American Journal of Roentgenology (n=11). These articles were published between 1939 and 2006 with a mean of 664.3 citations per article (range, 371-6931). Seventy-eight articles were published after 1979, 57 originated from the United States, and 69 were original articles. The most common subspecialties of study were interventional radiology (n=19), neuroradiology (n=15), and breast imaging (n=11). The main topics of articles were radiofrequency ablation of hepatic tumors (n=9), followed by receiver operating characteristic curves (n=6). Our study presents a detailed list and analysis of the 100 top-cited articles published in radiology journals, which provides insight into historical developments in the field of radiology.
Usage of insecure E-mail services among researchers with different scientific background.

Free web‑based e-mail services are considered to have more security flaws than institutional ones, but they are frequently used among scientific researchers for professional communication. The aim of this study was to analyze frequency of usage of the insecure free e-mail services for professional communication among biomedical, economical and technical researchers, who published papers in one of three different journals: Croatian Medical Journal, Automatika and Economic Research. Contact details of the authors who provided their e‑mail address from the papers published in those three journals during one year period were collected. These e‑mail addresses were collected from the electronic archive of the journals in question. The domains of all e‑mail addresses were assessed and contacts were categorized into three groups according to the following types: world-wide known free web‑based e‑mail services, national Internet Service Provider (ISP) e-mail services, and institutional or corporate e-mail addresses. The proportion of authors using free web-based e-mail services, the least secure group type, was highest among biomedical researchers (17.8%) while every e‑mail address collected from the technical journal belonged to the secured institutional e‑mail group type. It seems that all researchers from the technical scientific field and most of the researchers from the economical field value good security practice and use more secure systems for professional communication. High percentage of the biomedical researchers who use insecure e‑mail services may mean that they need to be warned of the possible security disadvantages of those kinds of e‑mail addresses.
Top-cited articles of the last 30 years (1985-2014) in otolaryngology - head and neck surgery.
Lenzi, R; Fortunato, S; Muscatello, L
2016-02-01
The frequency with which a scientific article is cited by other studies is one way to measure its academic influence. A comprehensive search was performed to identify journal articles in the otorhinolaryngology subject category of the 2013 Journal Citation Report Science Edition over the last 30 years (1985-2014). The 100 most cited articles were reviewed and basic information including the publication year, country of origin, source journal, article type and research field was collected. The 100 most cited articles were published in 15 of the 44 otorhinolaryngology journals. The number of citations per article ranged between 208 and 1559. The leading research field was otology and neurotology (n = 50), followed by rhinology (n = 23) and head and neck surgery (n = 11). Most papers originated in the USA (n = 64). The possibility of an article being cited is influenced by the publication language, country of origin and source journal.

Factors associated with the Journal Impact Factor (JIF) for Urology and Nephrology Journals
Sewell, Joseph M.; Adejoro, Oluwakayode O.; Fleck, Joseph R.; Wolfson, Julian A.; Konety, Badrinath R.
2015-01-01
ABSTRACT Purpose: The Journal Impact Factor (JIF) is an index used to compare a journal's quality among academic journals and it is commonly used as a proxy for journal quality. We sought to examine the JIF in order to elucidate the main predictors of the index while generating awareness among scientific community regarding need to modify the index calculation in the attempt to turn it more accurate. Materials and Methods: Under the Urology and Nephrology category in the Journal Citations Report Website, the top 17 Journals by JIF in 2011 were chosen for the study. All manuscripts’ abstracts published from 2009-2010 were reviewed; each article was categorized based on its research design (Retrospective, Review, etc). T and correlation tests were performed for categorical and continuous variables respectively. The JIF was the dependent variable. All variables were then included in a multivariate model. Results: 23,012 articles from seventeen journals were evaluated with a median of 1,048 (range=78-6,342) articles per journal. Journals with a society affiliation were associated with a higher JIF (p=0.05). Self-citations (rho=0.57, p=0.02), citations for citable articles (rho=0.73, p=0.001), citations to non-citable articles (rho=0.65, p=0.0046), and retrospective studies (rho=-0.51, p=0.03) showed a strong correlation. Slight modifications to include the non-citable articles in the denominator yield drastic changes in the JIF and the ranking of the journals. Conclusion: The JIF appears to be closely associated with the number of citable articles published. A change in the formula for calculating JIF to include all types of published articles in the denominator would result in a more accurate representation. PMID:26742962
Disability research in counseling psychology journals: a 20-year content analysis.
Foley-Nicpon, Megan; Lee, Sharon
2012-07-01
We conducted an exploratory content analysis of disability research in 5 major counseling psychology journals between 1990 and 2010. The goal was to review the counseling psychology literature to better understand the prevalence of disability research, identify research methods most often conducted, and elucidate the types of concerns most studied. We searched 5 journals (Journal of Counseling & Development, Journal of Counseling Psychology, The Counseling Psychologist, Journal of Multicultural Counseling and Development, and Cultural Diversity and Ethnic Minority Psychology) using keywords derived from disability terms defined by the Individuals With Disabilities Education Improvement Act of 2004 (IDEA). Articles were categorized by methodology and disability category examined. We found that disability research continues to comprise an extremely small amount (from less than 1% to 2.7%) of the counseling psychology literature, with the frequency of articles plateauing in recent years. The research design of articles published has changed, with an increased number of empirical articles and a decrease in literature reviews. We conclude by calling for increased empirical investigation of disability among journals specific to counseling psychology to recognize disability as an important aspect of diversity within the field.

We aimed to determine the quantity and quality of research output of selected Asian countries in the field of total knee arthroplasty (TKA) in the last 10 years. Top 15 Asian countries were selected according to their gross domestic product. The Science Citation Index Expanded database was used to search for the literature published between 2004 and 2013 using "Total Knee Arthroplasty". The numbers of articles, journals and citations and the contribution of each country were analyzed. The articles were classified according to the type of study and the relative proportion of each type was analyzed. Asian surgeons have increasingly contributed to orthopedic literature on TKA for the past 10 years, but the dominant contribution came from only a few countries. The total number of articles published by Asian countries increased by 261%, with Japan producing most of the studies and China showing the maximum growth rate. The majority of studies were published in low impact factor journals. Korea published the highest proportion of articles in high impact factor journals. Clinical papers were most frequent. Our identification of research productivity pertaining to TKA among Asian countries gives a unique insight into the level of academic research in the field of TKA in these countries. There is a need to improve the quality of research to enhance the publishing power in high impact journals as well as the need for more basic research and epidemiological studies considering the unique differences among Asian patients undergoing TKA.

Sharing all types of clinical data and harmonizing journal standards.
Barbui, Corrado
2016-04-03
Despite recent efforts to enforce policies requiring the sharing of data underlying clinical findings, current policies of biomedical journals remain largely heterogeneous. As this heterogeneity does not optimally serve the cause of data sharing, a first step towards better harmonization would be the requirement of a data sharing statement for all clinical studies and not simply for randomized studies. Although the publication of a data sharing statement does not imply that all data is made readily available, such a policy would swiftly implement a cultural change in the definition of scientific outputs. Currently, a scientific output only corresponds to a study report published in a medical journal, while in the near future it might consist of all materials described in the manuscript, including all relevant raw data. When such a cultural shift has been achieved, the logical conclusion would be for biomedical journals to require authors to make all data fully available without restriction as a condition for publication.

The aim of this study was to present characteristics and publication patterns of studies arise from orthopedic theses obtained from National Thesis Center; database in terms of publication years, study types, topics, level of evidence between 1974 and 2014. Firstly, National Thesis Center database was searched for orthopedics and Traumatology theses. The theses, which their summary or full text were available were included in the study. The topics, study types and quality of study designs were reviewed. Then theses were searched in the PubMed database. Journals of published theses were classified according to category, scope and impact factors of the year 2014. 1508 theses were included into the study. Clinical studies comprised 71,7% of the theses, while 25,6% of the theses were non-clinical experimental and 2,7% of the theses were observational studies. Clinical studies were Level I in 8,6% (n = 93) and Level II in 5,8% of the theses (n = 63). A total of 224 theses (14,9%) were published in the journals indexed in PubMed database from 1974 to 2012. Fifty-two (23,2%) were published in SCI; 136 theses (60,7%) were published in SCI-E journals and 36 theses (16%) were published in other Journals indexed in PubMed. The quantity and quality of published theses need to be improved and effective measures should be taken to promote quality of theses. Theses from universities and Training hospitals which did not allow open access, and; incomplete records of the National Thesis Center database were major limitations of this study.

Poster presentations at major meetings serve to rapidly present and share study results with the scientific community. On the other hand, full-text publication of abstracts in peer-reviewed journals provides dissemination of knowledge. The purpose of this study was to evaluate the publication rate of abstracts presented at the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Meeting, to assess the factors influencing publication and determine the impact factor of these journals. All poster abstracts presented at the 2002 IFCC Meeting were included in the study. A Medline search was performed to identify a matching journal article. Topics, country of origin, study type, study center and publication year were tabulated. Journals and impact factors of publication were noted. Out of 900 presented abstracts, 125 (13.9%) were published as full-text articles. Publication rates according to topics of the meeting, country of origin and university affiliation demonstrated significant differences. Abstracts from multi-centered studies had higher publication rates, and the journals they were published in had higher impact factors than single center studies. The median impact factor of the journals was 2.093. According to regression analysis, the major predictors for publication were interventional research and university affiliation (odds ratios 2.916 and 1.782, respectively; p < 0.05). The publication rate for abstracts of this clinical chemistry meeting was lower than rates from other fields of medicine. Factors leading to failure require elucidation. Encouraging authors to submit their presentations for full-text publication might improve the rate of publication.

To identify and analyse the 100 most cited papers on stress in nurses published in nursing journals. The number of citations an article receives is an index of its impact on the scientific community. An analysis of the most cited articles on stress in nursing would allow us to identify the most important articles and to obtain information about this area of knowledge. A retrospective bibliometric analysis. In 2016, 111 journals belonging to the "nursing" category were identified in the Science and Social Science Citation Index. A search was performed of the Science Core Collection Website for articles on stress published in these journals. The topic, type of article, publishing journal, countries and institutions of origin and year of publication were extracted from the articles. The impact factor, immediacy index, journal country and publisher and h index were collected from the Institute for Scientific Information. The citation density, citation tendency and Bradford's law were calculated. They identified articles were mostly empirical quantitative studies with a transversal design, published from 1975 - 2011 in 23 journals. They were signed by 233 authors, most of whom are English-speaking from the USA and UK. The core distribution of the publications comprises a single journal, the Journal of Advanced Nursing. The study of stress in nursing has shown increased visibility and recognition each decade. The most recent articles have the highest number of citations, are the highest in rank and have the higher citation densities. © 2018 John Wiley & Sons Ltd.

The ethical behavior of authors, editors, and journals is increasingly placed in the spotlight, by both the public and the research community. Disclosures and conflict of interest (COI) statements of publishing authors represent one important aspect. We aimed to unravel the current management of disclosures, COI, and funding statements in the subspecialty urogynecology. A bibliometric study was carried out. We included six journals that published urogynecology articles between January and December 2013. All original articles, reviews, and opinion articles were assessed for the presence of disclosure/COI and funding statements. Information given on the official disclosure form was compared with information given in the final article (International Urogynecology Journal). All journals investigated require disclosure and funding statements in their instructions to authors. Of the 434 articles included, almost all contained a disclosure statement (98-100 %). Funding statements were present in 41-100 % of articles, indicating a difference in journal type (50 % on average among urogynecology journals; 75 % on average among general gynecology journals). The main source of funding was "grants" (58 %), followed by "none" (16 %), "industry" (16 %), and lastly "hospital/university" (10 %). Disclosure statements in the article were identical to the official disclosure form in 80 % (IUJ). Disclosure/COI statements were included in almost all urogynecology articles investigated. Their content, however, is sometimes incomplete and should possibly be monitored more closely by journals and authors. Despite universal requirements of journals, the reporting of funding seems inconsistent. This issue in addition to the completeness of disclosures should be given more attention.

Objective A dissertation is a scientific document. However, if it is not published in a scientific journal, it will gain access to only a limited audience and thus will be unable to achieve its objective. Nevertheless, the rate of publishing in journals is not high among dissertations. In this study, we aimed to investigate the publishing rates of general surgery dissertations in journals and the total number of citations. Material and Methods All medical dissertations that have been prepared at general surgery departments of university hospitals and presented between the years 2006 and 2008 were analyzed. The authors checked whether the dissertations were published in a journal or not, by searching the dissertation in 4 different resources with the name of their authors. Results Two hundred and thirty-two dissertations were included. Half of those dissertations were experimental animal studies. Seventy dissertations were published in various journals. Fifty one (22%) of these were published in Science Citation Index Expanded journals, while 19 (8.1%) of them were published in Turkish non-Science Citation Index Expanded journals. There was no significant difference in terms of publishing rates between study types. The number of annual citations per article was 1.1. The writer of the dissertation was the first author in 35 (68,6%) articles. Conclusion The publishing rates of dissertations in general surgery is low, with only 22% being published in Science Citation Index Expanded journals. The citation rate was also detected to be low in our study. Consequently, a dissertation should be considered as a scientific research study and planned as such, not as obligatory assignments. The publishing rates of dissertations should be increased, and authors should be led and encouraged to publish their dissertations. PMID:28740947

Mapping the literature of nurse practitioners.
Shams, Marie-Lise Antoun
2006-04-01
This study was designed to identify core journals for the nurse practitioner specialty and to determine the extent of their indexing in bibliographic databases. As part of a larger project for mapping the literature of nursing, this study followed a common methodology based on citation analysis. Four journals designated by nurse practitioners as sources for their practice information were selected. All cited references were analyzed to determine format types and publication years. Bradford's Law of Scattering was applied to identify core journals. Nine bibliographic databases were searched to estimate the index coverage of the core titles. The findings indicate that nurse practitioners rely primarily on journals (72.0%) followed by books (20.4%) for their professional knowledge. The majority of the identified core journals belong to non-nursing disciplines. This is reflected in the indexing coverage results: PubMed/MEDLINE more comprehensively indexes the core titles than CINAHL does. Nurse practitioners, as primary care providers, consult medical as well as nursing sources for their information. The implications of the citation analysis findings are significant for collection development librarians and indexing services.

The methods and results of health research are documented in study protocols, full study reports (detailing all analyses), journal reports, and participant-level datasets. However, protocols, full study reports, and participant-level datasets are rarely available, and journal reports are available for only half of all studies and are plagued by selective reporting of methods and results. Furthermore, information provided in study protocols and reports varies in quality and is often incomplete. When full information about studies is inaccessible, billions of dollars in investment are wasted, bias is introduced, and research and care of patients are detrimentally affected. To help to improve this situation at a systemic level, three main actions are warranted. First, academic institutions and funders should reward investigators who fully disseminate their research protocols, reports, and participant-level datasets. Second, standards for the content of protocols and full study reports and for data sharing practices should be rigorously developed and adopted for all types of health research. Finally, journals, funders, sponsors, research ethics committees, regulators, and legislators should endorse and enforce policies supporting study registration and wide availability of journal reports, full study reports, and participant-level datasets.

To identify sports medicine-related clinical trial research articles in the PubMed MEDLINE database published between 1996 and 2005 and conduct a review and analysis of topics of research, experimental designs, journals of publication and the internationality of authorships. Sports medicine research is international in scope with improving study methodology and an evolution of topics. Structured review of articles identified in a search of a large electronic medical database. PubMed MEDLINE database. Sports medicine-related clinical research trials published between 1996 and 2005. Review and analysis of articles that meet inclusion criteria. Articles were examined for study topics, research methods, experimental subject characteristics, journal of publication, lead authors and journal countries of origin and language of publication. The search retrieved 414 articles, of which 379 (345 English language and 34 non-English language) met the inclusion criteria. The number of publications increased steadily during the study period. Randomised clinical trials were the most common study type and the "diagnosis, management and treatment of sports-related injuries and conditions" was the most popular study topic. The knee, ankle/foot and shoulder were the most frequent anatomical sites of study. Soccer players and runners were the favourite study subjects. The American Journal of Sports Medicine had the highest number of publications and shared the greatest international diversity of authorships with the British Journal of Sports Medicine. The USA, Australia, Germany and the UK produced a good number of the lead authorships. In all, 91% of articles and 88% of journals were published in English. Sports medicine-related research is internationally diverse, clinical trial publications are increasing and the sophistication of research design may be improving.

Objectives: This study was designed to document the state of open access (OA) in the biomedical field in 2005. Methods: PubMed was used to collect bibliographic data on target articles published in 2005. PubMed, Google Scholar, Google, and OAIster were then used to establish the availability of free full text online for these publications. Articles were analyzed by type of OA, country, type of article, impact factor, publisher, and publishing model to provide insight into the current state of OA. Results: Twenty-seven percent of all the articles were accessible as OA articles. More than 70% of the OA articles were provided through journal websites. Mid-rank commercial publishers often provided OA articles in OA journals, while society publishers tended to provide OA articles in the context of a traditional subscription model. The rate of OA articles available from the websites of individual authors or in institutional repositories was quite low. Discussion/Conclusions: In 2005, OA in the biomedical field was achieved under an umbrella of existing scholarly communication systems. Typically, OA articles were published as part of subscription journals published by scholarly societies. OA journals published by BioMed Central contributed to a small portion of all OA articles.

Publication retraction is a mechanism to preserve the scientific literature against publications that contain seriously flawed or erroneous data, redundant publication, plagiarism, unethical research, and other features that compromise the integrity of science. An increase in the occurrence of retractions in recent years has been reported. Nevertheless, there is scarce information on this topic concerning publications in dentistry and related specialties. Thus, this study aimed to investigate retracted papers published in dental journals. Data collection included an exploratory search in PubMed and a specific search in SCImago Journal Rank indexed journals, complemented by the cases reported on the Retraction Watch website and in PubMed. All 167 dental journals included in SCImago were searched for identification of retracted articles up to March 2016. The selected retracted articles and their corresponding retraction notices were recorded and assessed for classification according to the reason for retraction and other additional information. Forty of the 167 journals scrutinised at SCImago (23.9%) had at least one retracted article, and four additional journals were identified from the Retraction Watch website. A total of 72 retracted found were retracted for the reasons: redundant publication (20.8%), plagiarism (18.1%), misconduct (13.8%), overlap (13.6%) and honest error (9.7%). Higher number of retractions were reported in those journals with cites/doc <2.0-n = 49 (74.2%). The types of studies were mainly laboratory studies (34.7%), case reports (22.2%) and review articles (13.9%). The approach to ethical problems in papers published in dental scientific journals is still incipient; retractions were mostly due to the authors' malpractice and were more frequently related to journals with less impact.

The study of classic papers permits analysis of the past, present, and future of a specific area of knowledge. This type of analysis is becoming more frequent and more sophisticated. Our objective was to use the H-classics method, based on the h-index, to analyze classic papers in Implant Dentistry, Periodontics, and Oral Surgery (ID, P, and OS). First, an electronic search of documents related to ID, P, and OS was conducted in journals indexed in Journal Citation Reports (JCR) 2014 within the category 'Dentistry, Oral Surgery & Medicine'. Second, Web of Knowledge databases were searched using Mesh terms related to ID, P, and OS. Finally, the H-classics method was applied to select the classic articles in these disciplines, collecting data on associated research areas, document type, country, institutions, and authors. Of 267,611 documents related to ID, P, and OS retrieved from JCR journals (2014), 248 were selected as H-classics. They were published in 35 journals between 1953 and 2009, most frequently in the Journal of Clinical Periodontology (18.95%), the Journal of Periodontology (18.54%), International Journal of Oral and Maxillofacial Implants (9.27%), and Clinical Oral Implant Research (6.04%). These classic articles derived from the USA in 49.59% of cases and from Europe in 47.58%, while the most frequent host institution was the University of Gothenburg (17.74%) and the most frequent authors were J. Lindhe (10.48%) and S. Socransky (8.06%). The H-classics approach offers an objective method to identify core knowledge in clinical disciplines such as ID, P, and OS. © 2016 John Wiley & Sons A/S.

To describe and assess the consumption of the information consulted and cited in the articles published in the journal Nutrición Hospitalaria for the period 2001--2005 by means of bibliometric analysis. Cross-sectional descriptive analysis of the results obtained from the analysis of the lists of bibliographic references of the articles published at Nutrición Hospitalaria. We studied the most cited journals, the signatures index, the type of document referred, the publication language, the distribution of geographical origin, and obsolescence and readiness index. We took into account all types of documents with the exception of Communications to Congresses. 345 articles were published at Nutr Hosp, containing 8,113 bibliographic references, with a median of 18, a maximum of 136 and minimum of 0 BR per article. The mean (rate of publications per published article during the specified period) is 23.52 (95% IC 20.93-26.10) and the mean at 5% is 20.66 per article. The 25th and 75th percentiles are 6 and 32, respectively, the interquartile interval being 26 BR per document. The semi-period of Burton and Kebler is 7 years and the Price Index is 38.18%. The bibliographic references, the consumption of information, of the articles published at Nutrición Hospitalaria present parameters similar to other journals on health science. However, good data on obsolescence are observed, which reveal the good validity of most of the references studied.

The increased number of articles published in nutrition is a reflection of the relevance to scientific community. The characteristics and quality of nutritional studies determine whether readers can obtain valid conclusions from them, as well as their usefulness for evidence-based strategic policies. To determine the characteristics of papers published in nutrition journals. Descriptive study design. We reviewed 330 original papers published between January-June 2007. From: American Journal of Clinical Nutrition (AJCN), Journal of Nutrition, European Journal Nutrition, European Journal of Clinical Nutrition and Public Health Nutrition. We classified them according to the subjects studied; risk factors, study design and country of origin. Almost half the papers studied healthy people (53.3%). The most frequent illness was obesity (13.9%). Food consumption is the most frequent risk factor (63.3%). Social factors appear exclusively only in 3.6% of the papers. Clinical trials were the most common analytical design (31.8%), mainly in the AJCN (45.6%). Cross-sectional studies were the most frequent type of observational design (37.9%). Ten countries produced over half of the papers (51.3%). The US publishes the highest number of papers (20.6%), whilst developing countries make only scarce contributions to scientific literature on nutrition. Most of the papers had inferential power. They generally studied both healthy and sick subjects, coinciding with the aims of international scientific policies. However, the topics covered reflect a clear bias, prioritizing problems pertaining to developed countries. Social determinants of health should also be considered, along with behavioral and biological risk factors.
Economic content in medical journal advertisements for medical devices and prescription drugs.
Ackerly, D Clay; Glickman, Seth W; Schulman, Kevin A
2010-01-01
Previous studies of economic content in medical journal advertisements have not examined all types of economic content and have not included advertisements for medical devices. To examine trends in the economic content of medical device and pharmaceutical advertisements in medical journals. Three reviewers examined pharmaceutical and medical device advertisements in six leading medical journals from 1997 through 2006. Product characteristics, economic claims and evidence to support those claims were evaluated. Economic content appeared in 23.5% (561/2389) of pharmaceutical and device advertisements; 11.9% made market share claims and 12.7% made other economic claims. From 1997 through 2006, the percentage of medical device advertisements containing economic content declined from 26.7% to 6.7% (p = 0.02), whereas the percentage of pharmaceutical advertisements containing economic content remained stable (21.6-22.0%; p = 0.99). For pharmaceuticals, price claims declined significantly (15.7-4.2%; p < 0.01) and market share claims increased (2.8-11.5%; p = 0.09), and both consistently presented evidence (83% and 98%, respectively) while other types did not (e.g. 13.5% of formulary claims). Medical device economic claims differed from pharmaceutical economic claims; they made fewer market share claims (1.1% vs 12.8%) but more cost-effectiveness (6.5% vs 0.6%) and reimbursement (4.9% vs 0.8%) claims. Fewer than 2% of device advertisements with economic claims provided supporting evidence. The prevalence and type of economic content in pharmaceutical and device advertisements changed between 1997 and 2006, which may reflect evolving market dynamics, such as changes in reimbursement systems. Furthermore, the lack of supporting evidence in medical device advertisements and pharmaceutical formulary claims are potential areas of concern that require additional scrutiny by regulators and journal editors.

To help authors design rigorous studies and prepare clear and informative manuscripts, improve the transparency of editorial decisions, and raise the bar on educational scholarship, the Deputy Editors of the Journal of General Internal Medicine articulate standards for medical education submissions to the Journal. General standards include: (1) quality questions, (2) quality methods to match the questions, (3) insightful interpretation of findings, (4) transparent, unbiased reporting, and (5) attention to human subjects’ protection and ethical research conduct. Additional standards for specific study types are described. We hope these proposed standards will generate discussion that will foster their continued evolution.

The Prevalence of Inappropriate Image Duplication in Biomedical Research Publications
Casadevall, Arturo; Fang, Ferric C.
2016-01-01
ABSTRACT Inaccurate data in scientific papers can result from honest error or intentional falsification. This study attempted to determine the percentage of published papers that contain inappropriate image duplication, a specific type of inaccurate data. The images from a total of 20,621 papers published in 40 scientific journals from 1995 to 2014 were visually screened. Overall, 3.8% of published papers contained problematic figures, with at least half exhibiting features suggestive of deliberate manipulation. The prevalence of papers with problematic images has risen markedly during the past decade. Additional papers written by authors of papers with problematic images had an increased likelihood of containing problematic images as well. As this analysis focused only on one type of data, it is likely that the actual prevalence of inaccurate data in the published literature is higher. The marked variation in the frequency of problematic images among journals suggests that journal practices, such as prepublication image screening, influence the quality of the scientific literature.

This investigation employs categorical content analysis processes as a mechanism to examine trends and issues in a sampling of highly cited (100+) literature in special education journals. The authors had two goals: (a) broadly identifying trends across publication type, content area, and methodology and (b) specifically identifying articles with disaggregated outcomes for students with learning disabilities (LD). Content analyses were conducted across highly cited (100+) articles published during a 20-year period (1992-2013) in a sample ( n = 3) of journals focused primarily on LD, and in one broad, cross-categorical journal recognized for its impact in the field. Results indicated trends in the article type (i.e., commentary and position papers), content (i.e., reading and behavior), and methodology (i.e., small proportions of experimental and quasi-experimental designs). Results also revealed stability in the proportion of intervention research studies when compared to previous analyses and a decline in the proportion of those that disaggregated data specifically for students with LD.

Heinzl et al. (1985) reports that experiments in ink-jets to produce drawings or signals occurred as early as 1930. Various companies such as IBM and Pitney-Bowes have conducted extensive studies on these devices for many years. Many such reports are available in such journals as the IBM Journal of Research and Development. While numerous articles have been published on the jetting characteristics of ink and water, the literature is rather limited on fluids such as waxes (Gao & Sonin 1994) or non-water based fluids (Passow, et al. 1993). This present study extends the knowledge base to determine the performance of molten waxes in "ink-jet" type printers for rapid prototyping. The purpose of this research was to qualitatively and quantitatively study the droplet formation of a drop-on-demand ink-jet type nozzle system for rapid prototyping.

To determine whether it is possible to contact authors of previously published papers via email. A cross sectional study of the Emergency Medicine Journal for 2001. 118 articles were included in the study. The response rate from those with valid email addresses was 73%. There was no statistical difference between the type of email address used and the address being invalid (p=0.392) or between the type of article and the likelihood of a reply (p=0.197). More responses were obtained from work addresses when compared with Hotmail addresses (86% v 57%, p=0.02). Email is a valid means of contacting authors of previously published articles, particularly within the emergency medicine specialty. A work based email address may be a more valid means of contact than a Hotmail address.

The present paper is based on experimental studies and numerical simulations on the surface fatigue failure of the PTFE-bronze layered journal bearings under real-time loading. ‘Permaglide Plain Bearings P10’ type journal bearings were experimentally tested under different real time dynamic loadings by using real time journal bearing test system in our laboratory. The journal bearing consists of a PTFE-bronze layer approximately 0.32 mm thick on the steel support layer with 2.18 mm thick. Two different approaches have been considered with in experiments: (i) under real- time constant loading with varying bearing widths, (ii) under different real-time loadings at constant bearing widths. Fatigue regions, micro-crack dispersion and stress distributions occurred at the journal bearing were experimentally and theoretically investigated. The relation between fatigue region and pressure distributions were investigated by determining the circumferential pressure distribution under real-time dynamic loadings for the position of every 10° crank angles. In the theoretical part; stress and deformation distributions at the surface of the journal bearing analysed by using finite element methods to determine the relationship between stress and fatigue behaviour. As a result of this study, the maximum oil pressure and fatigue cracks were observed in the most heavily loaded regions of the bearing surface. Experimental results show that PTFE-Bronze layered journal bearings fatigue behaviour is better than the bearings include white metal alloy.

Dissemination of educational research is critical to improving medical education, promotion of faculty and ultimately patient care. The objective of this study was to identify the top 25 cited education articles in the emergency medicine (EM) literature and the top 25 cited EM education articles in all journals, as well as report on the characteristics of the articles. Two searches were conducted in the Web of Science in June 2016 using a list of education-related search terms. We searched 19 EM journals for education articles as well as all other literature for EM education-related articles. Articles identified were reviewed for citation count, article type, journal, authors, and publication year. With regards to EM journals, the greatest number of articles were classified as articles/reviews, followed by research articles on topics such as deliberate practice (cited 266 times) and cognitive errors (cited 201 times). In contrast in the non-EM journals, research articles were predominant. Both searches found several simulation and ultrasound articles to be included. The most common EM journal was Academic Emergency Medicine (n = 18), and Academic Medicine was the most common non-EM journal (n=5). A reasonable number of articles included external funding sources (6 EM articles and 13 non-EM articles.). This study identified the most frequently cited medical education articles in the field of EM education, published in EM journals as well as all other journals indexed in Web of Science. The results identify impactful articles to medical education, providing a resource to educators while identifying trends that may be used to guide EM educational research and publishing efforts.

Sharing of experimental clinical research data usually happens between individuals or research groups rather than via public repositories, in part due to the need to protect research participant privacy. This approach to data sharing makes it difficult to connect journal articles with their underlying datasets and is often insufficient for ensuring access to data in the long term. Voluntary data sharing services such as the Yale Open Data Access (YODA) and Clinical Study Data Request (CSDR) projects have increased accessibility to clinical datasets for secondary uses while protecting patient privacy and the legitimacy of secondary analyses but these resources are generally disconnected from journal articles-where researchers typically search for reliable information to inform future research. New scholarly journal and article types dedicated to increasing accessibility of research data have emerged in recent years and, in general, journals are developing stronger links with data repositories. There is a need for increased collaboration between journals, data repositories, researchers, funders, and voluntary data sharing services to increase the visibility and reliability of clinical research. Using the journal Scientific Data as a case study, we propose and show examples of changes to the format and peer-review process for journal articles to more robustly link them to data that are only available on request. We also propose additional features for data repositories to better accommodate non-public clinical datasets, including Data Use Agreements (DUAs).
Anatomy of open access publishing: a study of longitudinal development and internal structure
2012-01-01
Background Open access (OA) is a revolutionary way of providing access to the scholarly journal literature made possible by the Internet. The primary aim of this study was to measure the volume of scientific articles published in full immediate OA journals from 2000 to 2011, while observing longitudinal internal shifts in the structure of OA publishing concerning revenue models, publisher types and relative distribution among scientific disciplines. The secondary aim was to measure the share of OA articles of all journal articles, including articles made OA by publishers with a delay and individual author-paid OA articles in subscription journals (hybrid OA), as these subsets of OA publishing have mostly been ignored in previous studies. Methods Stratified random sampling of journals in the Directory of Open Access Journals (n = 787) was performed. The annual publication volumes spanning 2000 to 2011 were retrieved from major publication indexes and through manual data collection. Results An estimated 340,000 articles were published by 6,713 full immediate OA journals during 2011. OA journals requiring article-processing charges have become increasingly common, publishing 166,700 articles in 2011 (49% of all OA articles). This growth is related to the growth of commercial publishers, who, despite only a marginal presence a decade ago, have grown to become key actors on the OA scene, responsible for 120,000 of the articles published in 2011. Publication volume has grown within all major scientific disciplines, however, biomedicine has seen a particularly rapid 16-fold growth between 2000 (7,400 articles) and 2011 (120,900 articles). Over the past decade, OA journal publishing has steadily increased its relative share of all scholarly journal articles by about 1% annually. Approximately 17% of the 1.66 million articles published during 2011 and indexed in the most comprehensive article-level index of scholarly articles (Scopus) are available OA through journal publishers, most articles immediately (12%) but some within 12 months of publication (5%). Conclusions OA journal publishing is disrupting the dominant subscription-based model of scientific publishing, having rapidly grown in relative annual share of published journal articles during the last decade.

The hyperoctahedral group acting on icons/Journals/Common/BbbR" ALT="BbbR" ALIGN="TOP"/>N is the Weyl group of type B and is associated with a two-parameter family of differential-difference operators {Ti:1icons/Journals/Common/leq" ALT="leq" ALIGN="TOP"/> iicons/Journals/Common/leq" ALT="leq" ALIGN="TOP"/> N}. These operators are analogous to partial derivative operators. This paper finds all the polynomials h on icons/Journals/Common/BbbR" ALT="BbbR" ALIGN="TOP"/>N which are harmonic, icons/Journals/Common/Delta" ALT="Delta" ALIGN="TOP"/>Bh = 0 and annihilated by Ti for i>2, where the Laplacian 0305-4470/32/46/308/img1" ALT="(sum). They are given explicitly in terms of a novel basis of polynomials, defined by generating functions.

This paper presents the results of a study of bibliographies compiled from theses submitted in the period 2001-2005. The bibliographies have been studied to find out how research carried out at PRL is being used by the doctoral students. Resources are categorized by type of resource — book, journal article, proceedings, doctoral thesis, etc., to understand the usage of content procured by the library. The period of the study, 2001-2005, has been chosen because technology is changing so fast and so are the formats of scholarly communications. For the sake of convenience, only the "e-journals period" is considered for the sample.

We evaluated the authorship count of all original research and review articles published in prominent Urology journals to trend patterns in authorship over the last decade. Secondarily, we evaluated bibliometric assessments and sought to understand whether authorship count was associated with citation rate and each article's field-normalized measure of impact. Information on authorship count, date of publication, study type, journal of publication, citation rate, and relative citation ratio (RCR) was collected for all original research and review articles published in European Urology, Journal of Urology, Urology , and British Journal of Urology International between 2006 and 2016. We examined trends in authorship count over the past decade, as well as between journals and article types. 21,336 articles were analyzed, of which 19,527 (91.5%) were original research and 1,809 (8.5%) were review articles. Overall, number of authors increased 46.1% from 2006 to 2016. Authorship counts in original research articles increased by an average of 2.45 per manuscript (43.3% increase) over the decade analyzed. More dramatically, authorship counts in review articles increased by an average of 3.14 per manuscript (92.6% increase). Articles with higher authorship counts were associated with more citations and greater RCR (r=0.13, p<0.001). There is a global trend towards more authors per article in urology publications-in both original research publications and review articles, and across each of the individual journals evaluated. An increase in author count has also been associated with increased citations and measures of article impact.
Journal policy on ethics in scientific publication.
Callaham, Michael L
2003-01-01
Medical journals aspire to select, through peer review, the highest quality science, and their reputations depend on the trust of readers, authors, researchers, reviewers, and patients. Almost every aspect of this process involves important ethical principles and decisions, which are seldom explicitly stated and even less often shared with the readership. A comprehensive policy on publication ethics is summarized in this article. A few of the topics addressed are study design; research subject consent; definitions and responsibilities of authorship; declaration of paid writers; types of potential conflicts of interest; management of conflicts of interest on the part of authors, journal reviewers, and members of the editorial board; blinding and confidentiality of peer review; assessment of peer review quality; public identification of degree of peer review of various portions of the journal; criteria for manuscript decisions; management of author appeals; definitions of prior publication; plagiarism; criteria for advertising and relationship between advertising and editorial matter; allegations of misconduct and journal policies for responding to them; and the relationship of the journal to the sponsoring society. Our goal in publishing these policies is to make the guiding ethical principles of this journal accessible to all of our readers and contributors.

Journals provide instructions to prospective authors to facilitate the process of manuscript publication. The information provided under such instructions could be a potential opportunity to promote responsible conduct of research (RCR). We analyzed 74 Indian biomedical journals for the type of information provided in the "instructions to authors" section and adherence to the International Committee of Medical Journal Editors (ICMJE) recommendations. Among the 71 journals that had an "instructions to authors" section, 53 journals adhered to ICMJE recommendations. We discuss sections of the ICMJE recommendations detailed by Indian biomedical journals under the "instructions to authors" section and emphasize components that require greater exposure.

The study was undertaken to explore a bibliometric approach to quantitatively assess the research on detection of monosialoganglioside from 2002 to 2011. A bibliometric analysis based on the publications on Web of Science was performed using key words such as "monosialoganglioside", "colloidal gold", "high performance liquid chromatography" and "detection". (1) Research articles on the detection of monosialoganglioside; (2) researches on human and animal fundamentals, clinical trials and case reports; (3) article types: article, review, proceedings paper, note, letter, editorial material, discussion, book chapter; (4) Publication year: 2002-2011. (1) unrelated articles; (2) type of articles: correction; (3) articles from following databases: all databases related to social science and arts & humanities in Web of Science were excluded. (1) distribution of subject areas; (2) number of publications annually; (3) document type and language of publications; (4) distribution of institutions; (5) distribution of output in journals; (6) the number of countries in which the article is published; (7) top cited paper. Overall population stands at 1 880 research articles addressing detection of monosialoganglioside in Web of Science during the study period. Articles (1 599) were the most frequently used document type comprising 85.05%, followed by meeting abstracts, reviews and proceedings papers. The distribution of subject categories showed that monosialoganglioside research covered both clinical and basic science research. The USA, Japan, and Italy were the three most productive countries, and the publication numbers in the USA were highest with 559 papers. The University of Milan, Nagoya University, and Kinki University are the most productive institutions regarding detection of monosialoganglioside. In 559 articles published by Americans, Medical College of Georgia ranked the first with 30 articles, followed by University of Medicine and Dentistry of New Jersey (28 articles), Cornell University (24 articles) and Johns Hopkins University (24 articles). In 442 articles published by Japanese, Nagoya University ranked the first with 40 articles, followed by Kinki University (36 articles), and Dokkyo University (31 articles). Though the total number of publications by Japanese is smaller than Americans, the top three institutions published more publications than American institutions. There is a markedly increase in the number of publications on the subject detection of monosialoganglioside in 2004, which the peak in the past 10 years. The valley bottom of the subject appeared in 2005. In total, the research is increased with time prolonged. Journal of Neurochemistry, Journal of Biological Chemistry and Journal of Neuroimmunology were core subject journals in monosialoganglioside studies. This study highlights the topics in detection of monosialoganglioside research that are being published around the world.

Xiong, L.-Y.; Wu, G.; Hou, Y.; Liu, L.-Q.; Ling, M.-F.; Chen, C.-Z.
The research presented in this paper is aimed at the development of aerodynamic foil journal bearings applying to a small high speed cryogenic turboexpander. A small high speed cryogenic turboexpander is designed. Attention has been paid to the study of the effect of foil stiffness on the vibration performance of bearings. From rotation tests, it is clear that, with the proper choice of foil stiffness, the foil bearing presented here can possess sufficiently high stability. The maximum rotational speed obtained is greater than 230 000 rpm. Therefore, owing to its simplicity and high performance, this type of foil journal bearing can hopefully be applied to a small high speed cryogenic turboexpander.

Early research of work disability in the 1980s showed a complexity of factors influencing pain and health-related functional limitation at work; hence, multidisciplinary perspectives were necessary to understand the complex interplay between biomechanical, organizational, social, and psychological factors impacting work disability. To address this need, the Journal of Occupational Rehabilitation was founded in 1991 with the goal of providing a scientific, yet practical forum for presenting multidisciplinary research and practice in work disability. Now, the 20-year collection of articles in the Journal reflects important trends and directions in the field of occupational rehabilitation. We conducted a retrospective summary of the past 20 years of the Journal of Occupational Rehabilitation, including its inaugural goals and intent, rates of submission and acceptance, trends in the types of articles published, study topics, global distribution of authors, and future directions. The original goal of providing a multidisciplinary scientific and practical forum has been met, but current trends reflect a maturing scientific evidence base, with less representation of employer-based case studies and practical innovations. There has been a dramatic increase in the international representation of studies, authors, and peer reviewers outside of the US. Also, published studies now address work disability for a larger number of health concerns. Contributions to the Journal continue to reflect a multidisciplinary perspective, but the Journal has seen significant changes with respect to international representation, the expanding study of non-musculoskeletal sources of work disability, and the maturing scientific evidence base in the field of occupational rehabilitation. Future volumes of the Journal will likely reflect continuing changes in the global economy, workforce fitness, and job demands.

The aims of the present systematic literature analysis were to evaluate, over a 10-year period, the trend of the proportion of RCT, SR, MA published on endodontic surgery, and to investigate if the impact factor (IF) of the main endodontic Journals correlates with the proportion of RCT, SR, MA they publish. An electronic search of the RCT, SR and MA published on the topic "endodontic surgery" from 2001 to 2010 was performed on Medline and Cochrane CENTRAL database using specific search terms combined with Boolean operators. Endodontic Journals impact factor was retrieved by the Thomson Scientific database. The proportion of each study type over the total number of articles on endodontic surgery published per year was estimated. The correlation between the number of high-evidence level studies published on the main endodontic Journals and the IF of such Journals per year was estimated. From a total of 900 articles published in 2001-2010 on endodontic surgery, there were 114 studies of high evidence level. A significant increase of the proportion of either RCT, SR and MA over the years was found. A modest to unclear correlation was found between the Journal IF and the number of high-evidence articles published. There is a positive trend over the years among researchers in performing studies of good quality in endodontic surgery. The impact factor of endodontic Journals is not consistently influenced by publication of high-evidence level articles. Copyright © 2015 Elsevier Inc. All rights reserved.

Conduct a quantitative assessment of the number of papers contained in MEDLINE related to selected types of assistive technology (AT), and to identify journals publishing significant numbers of papers related to AT, and evaluate them with quantitative productivity and quality measures. Consecutive sample of all papers in MEDLINE identified by standard medical subject headings for selected types of AT from 1963-2003. Number of journals carrying AT papers, papers per journal (both total number and those specific to AT), journal impact factor, circulation, and number of AT citations per year over time for each area of AT. We present search terms, estimates of the numbers of AT citations in MEDLINE, the journals most likely to contain articles related to AT, journal impact factors, and journal circulations (when available). We also present the number of citations in various areas of AT over time from 1963-2003. Suggestions are presented for possible future modifications of the MEDLINE controlled vocabulary, based on terminology used in existing AT classifications schemes, such as ISO 9999. Research papers in the areas of AT examined showed publication across a wide variety of journals. There are a number of journals publishing articles in AT that have impact factors above the median. Some areas of AT have shown an increase in publications per year over time, while others have shown a more constant level of productivity.

Background Reporting of health research is often inadequate and incomplete. Complete and transparent reporting is imperative to enable readers to assess the validity of research findings for use in healthcare and policy decision-making. To this end, many guidelines, aimed at improving the quality of health research reports, have been developed for reporting a variety of research types. Despite efforts, many reporting guidelines are underused. In order to increase their uptake, evidence of their effectiveness is important and will provide authors, peer reviewers and editors with an important resource for use and implementation of pertinent guidance. The objective of this study was to assess whether endorsement of reporting guidelines by journals influences the completeness of reporting of health studies. Methods Guidelines providing a minimum set of items to guide authors in reporting a specific type of research, developed with explicit methodology, and using a consensus process will be identified from an earlier systematic review and from the EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network’s reporting guidelines library. MEDLINE, EMBASE, the Cochrane Methodology Register and Scopus will be searched for evaluations of those reporting guidelines; relevant evaluations from the recently conducted CONSORT systematic review will also be included. Single data extraction with 10% verification of study characteristics, 20% of outcomes and complete verification of aspects of study validity will be carried out. We will include evaluations of reporting guidelines that assess the completeness of reporting: (1) before and after journal endorsement, and/or (2) between endorsing and non-endorsing journals. For a given guideline, analyses will be conducted for individual and the total sum of items. When possible, standard, pooled effects with 99% confidence intervals using random effects models will be calculated. Discussion Evidence on which guidelines have been evaluated and which are associated with improved completeness of reporting is important for various stakeholders, including editors who consider which guidelines to endorse in their journal editorial policies.

The purpose of the study was to analyze the determinants of citations such as publication year, article type, article topic, article selected for a press release, number of articles previously published by the corresponding author, and publication language in a Spanish journal of public health. Observational study including all articles published in Gaceta Sanitaria during 2007-2011. We retrieved the number of citations from the ISI Web of Knowledge database in June 2013 and also information on other variables such as number of articles published by the corresponding author in the previous 5 years (searched through PubMed), selection for a press release, publication language, article type and topic, and others. We included 542 articles. Of these, 62.5% were cited in the period considered. We observed an increased odds ratio of citations for articles selected for a press release and also with the number of articles published previously by the corresponding author. Articles published in English do not seem to increase their citations. Certain externalities such as number of articles published by the corresponding author and being selected for a press release seem to influence the number of citations in national journals.

The source of research funding can result in bias, and its disclosure is essential in the publication of results. The aim of the study is to identify the frequency and type of sources of funding in the articles published by four Spanish biomedical journals published in Spanish. The frequency and type of financial disclosures in the articles published during 2012 in the ordinary numbers of Atención Primaria, Medicina Clínica, Revista Clínica Española and Revista Española de Cardiología were analyzed. Articles described as "Editorial", "Original article", "Consensus Document", "Review" and "Special Article" were considered. It was decided in each case whether or not the article included any funding disclosure and the type of the declared funding (public or private). Four hundred and twelve publications were analyzed. In 32.5% there was disclosure of funding: 38% in Atención Primaria, 27% in Medicina Clínica, 15% in Revista Clínica Española and 45% in Revista Española de Cardiología. By type of articles, 47% of original articles, 44% of consensus documents, 21% of reviews, 14% of special articles and 8% of editorials had a funding source. In 51.5% of the cases, funding was exclusively public, in 36.5% exclusively private and in 10% mixed. There is considerable variability in the disclosure of funding sources in articles appearing in these four Spanish biomedical journals. It would be necessary to improve the disclosure requirements of sources of funding, making them uniform, clear and transparent.

Nowadays, publishing highly-cited papers is important for researchers and editors. In this evidence-based study, the factors influencing the citability of published papers in the field of medicine have been identified. 200 papers indexed in Scopus (in two groups: highly-cited and lowly-cited) with 100 papers in each were studied. Needed data were manually collected with a researcher-made checklist. Data analysis was done in SPSS using descriptive and inferential statistics. Variables such as journal IF, journal rank, journal subject quartile, the first/corresponding author's h-index, the number of documents produced by the first/corresponding author, SJR and SNIP had significantly positive correlation with paper citability (p< .05). Other variables, including among others, paper age, paper type, the number of references, the number of authors, indexing institute and journal kind had not any relationship with paper citability (p> .05). the factors affecting the citability are among indicators relating to authors, publishing journals and published papers. Determining the extent to which these factors influence the citability of a paper needs further large-scaled research. Authors and editors searching for high-citedness should consider these factors when authoring and publishing papers.

This study aims to evaluate quantitatively the pediatric otorhinolaryngology (ORL) publications belonging to the ORL journals of the Science Citation Index (SCI) made by Turkey and other European countries between five year periods during 1995 and 2012. After SCI journals of 1995, 2000, 2005, 2010 and 2012 under the ORL heading were determined, the publications of all European countries in these journals were detected electronically using PubMed search engine. Then, the number of pediatric ORL publications and the journals which included them were determined and counted manually for each country. The number of total publications and pediatric ORL publications made by European countries in the mentioned years were 539/98, 737/123, 747/158, 757/175, and 746/171 respectively. Turkey was the country with the highest number of pediatric ORL publications in all years except 1995. It was detected that more than half of the total pediatric ORL publications were included in International Journal of Pediatric Otorhinolaryngology. It is pleasing that Turkey is ahead of many developed European countries in respect of the number of pediatric ORL publications. Further studies on type, evidence-based medicine or citation analysis of these publications will also enable qualitative evaluation.

In this study, we analysed the statistical association between e-journal use and research output at the institution level in South Korea by performing comparative and diachronic analyses, as well as the analysis by field. The datasets were compiled from four different sources: national reports on research output indicators in science fields, two statistics databases on higher education institutions open to the public, and e-journal usage statistics generated by 47 major publishers. Due to the different data sources utilized, a considerable number of missing values appeared in our datasets and various mapping issues required corrections prior to the analysis. Two techniques for handling missing data were applied and the impact of each technique was discussed. In order to compile the institutional data by field, journals were first mapped, and then the statistics were summarized according to subject field. We observed that e-journal use exhibited stronger correlations with the number of publications and the times cited, in contrast to the number of undergraduates, graduates, faculty members and the amount of research funds, and this was the case regardless of the NA handling method or author type. The difference between the maximum correlation for the amount of external research funding with two average indicators and that of the correlation for e-journal use were not significant. Statistically, the accountability of e-journal use for the average times cited per article and the average JIF was quite similar with external research funds. It was found that the number of e-journal articles used had a strong positive correlation (Pearson's correlation coefficients of r > 0.9, p < 0.05) with the number of articles published in SCI(E) journals and the times cited regardless of the author type, NA handling method or time period. We also observed that the top-five institutions in South Korea, with respect to the number of publications in SCI(E) journals, were generally across a balanced range of academic activities, while producing significant research output and using published material. Finally, we confirmed that the association of e-journal use with the two quantitative research indicators is strongly positive, even for the analyses by field, with the exception of the Arts and Humanities.

The monosialoganglioside (GM1) is a popular topic of research but the bibliometric analysis of GM1 over the decades in Science Citation Index-Expanded (SCI-E) remains poorly understood. To identify the global research and to improve the understanding of research trends in the GM1 field from 1942 to 2011. A bibliometric study. We performed a bibliometric analysis based on the SCI-E published by the Institute of Scientific Information. Articles closely related to GM1 were included. Exclusive criteria: (1) Articles related to gangliosidosis, disialo-ganglioside, trisialo-ganglioside or ganglioside GQIb. (2) Document types such as meeting abstracts, reviews, proceedings papers, notes, and letters. (1) Type of publication output; (2) number of author outputs; (3) distribution of output in subject categories; (4) publication distribution of countries; (5) distribution of output in journals, and (6) distribution of citations in each decade. During 1942 to 2011, there were 10 126 papers on GM1 that were added to the SCI. Articles (8 004) were the most frequently used document type comprising 79.0%, followed by meeting abstracts, reviews and proceedings papers. Research on GM1 could be found in the SCI from 1942, it was developed in the 1970s, greatly increased in the 1980s, and reached a peak in the 1990s, and it was slightly decreased in 2000. The distribution of subject categories showed that GM1 research covered both clinical and basic science research. The USA, Japan, and Germany were the three most productive countries, and the publication numbers in the USA were highest in all decades. The Journal of Biological Chemistry, Journal of Neurochemistry and Biochemistry were core subject journals in GM1 studies in each decade. This study highlights the topics in GM1 research that are being published around the world.

A bibliometric analysis of the 100 most influential papers in burns.
Joyce, C W; Kelly, J C; Sugrue, C
2014-02-01
The importance of a published paper to a particular area is reflected in the quantity of citations obtained from peers. In burns, it is unknown which papers have been the most influential on this specialty. The purpose of our study was to identify the 100 most cited papers in burns and to analyze their characteristics. Twenty-seven journals were chosen for analysis. These included high impact factor scientific journals and journals dedicated to burns and trauma. Only twelve of these journals contributed to the 100 most cited papers in burns and we analyzed each paper individually looking at its subject matter, authorship, article type, institution, country and year of publication. Our citation analysis revealed an interesting mix of clinical and scientific papers that documents the key landmarks in burn care over the past 66 years. Copyright © 2013 Elsevier Ltd and ISBI.

Objective Our study aimed to assess Turkish publications in Science Citation Index (SCI) and Science Citation Index Expanded (SCI-E) indexed journals in the field of ‘anaesthesiology’. Methods Journals related to ‘anaesthesiology’ in the Science Citation Index-Expanded database of ‘Thomson Reuter Web of Science’ were searched. The search engine of Institute for Scientific Information (ISI) Web of Science (WoS) was used in the advanced mode by typing ‘IS=ISSN number’ to identify publications in the journal. By typing ‘IS=ISSN number AND CU=Turkey’, Turkish papers on anaesthesiology were found. If Turkish and non-Turkish authors had collaborated, the article was included in the search when the corresponding author had provided a Turkey-based address. The catalogue information and statistics were used to determine Turkish publications as the percentage of total publications and the annual mean number of Turkish publications. In WoS, ‘SU=anesthesiology’ was used to determine the number, country, year and topic distributions of publications from 1975 to date and within the last 10 years. The citation numbers and h-indices were determined based on the country for publications within the last 10 years. Results From 1975 to the early 2000s Turkey was 20th in the list of countries with highest number of publications on anaesthesiology, however in the last 10 years Turkey moved up to 18th place. Its mean citation number has been 4.64, and it remains the 2nd lowest country pertaining to citations among the 22 countries with the most number of publications. According to the percentage of publications in the field of anaesthesiology, the journals with highest rate of Turkish publications were Revista Brasileira de Anestesiologia, European Journal of Anaesthesiology and Journal of Anesthesia. Conclusion In the field of anaesthesiology, the highest number of articles from Turkey was published in Revista Brasileira de Anestesiologia, European Journal of Anaesthesiology and Journal of Anesthesia. The mean citation number from these publications was 4.64. PMID:28377837
A framework for visual communication at Nature.
Krause, Kelly
2016-04-25
The scientific journal Nature, published weekly since 1869, serves as an excellent case study in visual communication. While journals are becoming increasingly specialist, Nature remains firmly multidisciplinary; and unlike many scientific journals, it contains original journalism, opinion pieces, and expert analysis in addition to peer-reviewed research papers. This variety of content types-covering an extensive range of scientific disciplines-translates into a wide and varied audience, and the need to employ an equally wide variety of communication styles.For example, a research paper may employ technical language to communicate to a highly specialized audience in that field, whereas a news story on the same subject will explain the science to an educated lay audience, often adding a wider context and stripping out acronyms. Each type of piece will use a communication approach tailored for its intended audience.This is true for visual content as well: the intended audience of a scientific figure, illustration or data visualization will determine the design approach to that visual. At Nature, given the high volume of content plus high quality standards, this process is applied in a fairly systematic way, using a framework to guide creative decision-making. That framework is described here, along with a discussion of best practices for the design of research figures and graphics by context. © The Author(s) 2016.

Introduction Dissemination of educational research is critical to improving medical education, promotion of faculty and ultimately patient care. The objective of this study was to identify the top 25 cited education articles in the emergency medicine (EM) literature and the top 25 cited EM education articles in all journals, as well as report on the characteristics of the articles. Methods Two searches were conducted in the Web of Science in June 2016 using a list of education-related search terms. We searched 19 EM journals for education articles as well as all other literature for EM education-related articles. Articles identified were reviewed for citation count, article type, journal, authors, and publication year. Results With regards to EM journals, the greatest number of articles were classified as articles/reviews, followed by research articles on topics such as deliberate practice (cited 266 times) and cognitive errors (cited 201 times). In contrast in the non-EM journals, research articles were predominant. Both searches found several simulation and ultrasound articles to be included. The most common EM journal was Academic Emergency Medicine (n = 18), and Academic Medicine was the most common non-EM journal (n=5). A reasonable number of articles included external funding sources (6 EM articles and 13 non-EM articles.) Conclusion This study identified the most frequently cited medical education articles in the field of EM education, published in EM journals as well as all other journals indexed in Web of Science. The results identify impactful articles to medical education, providing a resource to educators while identifying trends that may be used to guide EM educational research and publishing efforts.

To identify and describe controlled clinical trials (CCTs) published in Spanish Gynaecology and Obstetrics journals. In addition, to assess the quality of the CCTs on Assisted Reproduction Techniques (ART) identified in this project. In order to identify eligible CCTs, all Spanish Gynaecology and Obstetrics journals were handsearched. Handsearching was conducted following the guidelines provided by the Cochrane Collaboration, which state that each journal article must be carefully reviewed, including original articles and other types of studies, letters to the editor, abstracts, and conference presentations. The results of the handsearching process were compared with an electronic search conducted in MEDLINE (PubMed). A descriptive analysis of the main characteristics of the identified CCTs was performed, as well as a methodological assessment of CCTs on ART. Sixteen Gynaecology and Obstetrics journals were identified, four of which have been indexed in MEDLINE at some point, although not currently. The journal with the most CCTs was "Progresos de Obstetricia y Ginecología". A total of 235 CCTs were published in these journals, of which 29 were on ART. Most CCTs (216, 91.9%) were carried out in a hospital setting; 201 (89.4%) were unicentric. Obstetrics was the most studied subspecialty (46.4%). Among CCTs on ART, the risk of bias was predominantly high. The number of CCTs published in Spanish Gynaecology and Obstetrics journals is limited. CCTs on ART present deficiencies in the report of results and low methodological quality. It is advised that authors and journals adhere to the CONSORT statement and to the Cochrane Collaboration recommendations to reduce risk of bias when designing and disseminating research projects.

Background While the research design of articles published in medical journals and in some physical therapy journals has already been evaluated, this has not been investigated in Brazilian physical therapy journals. Objective To describe the research design used in all articles published in Brazilian scientific journals that are freely available, have high Qualis rankings, and are relevant to physical therapy over a 7-year period. Method We extracted the bibliometric data, research design, research type (human or animal), and clinical area for all articles published. The articles were grouped into their level of evidence, and descriptive analyses were performed. We calculated the frequency, proportions of articles, and 95% confidence interval of these proportions with each research design in each journal. We cross-tabulated the clinical areas with research designs (expressed as number and percentages). Results A total of 1,458 articles from four Brazilian journals were found: Revista Brasileira de Fisioterapia, Revista Fisioterapia em Movimento, Revista Fisioterapia e Pesquisa, and Revista Acta Fisiátrica. The majority of articles were classified as level II of evidence (60%), followed by level III (29%) and level I (10%). The most prevalent research designs were cross-sectional studies (38%), single-case or case-series studies, and narrative reviews. Most articles reported human research and were in the musculoskeletal, neurologic, and cardiothoracic areas. Conclusions Most of the research published in Brazilian physical therapy journals used levels II and III of evidence. Increasing the publication rate of systematic reviews and randomized controlled trials would provide more high-quality evidence to guide evidence-based physical therapy practice. PMID:24675913

While the research design of articles published in medical journals and in some physical therapy journals has already been evaluated, this has not been investigated in Brazilian physical therapy journals. Objective : To describe the research design used in all articles published in Brazilian scientific journals that are freely available, have high Qualis rankings, and are relevant to physical therapy over a 7-year period. We extracted the bibliometric data, research design, research type (human or animal), and clinical area for all articles published. The articles were grouped into their level of evidence, and descriptive analyses were performed. We calculated the frequency, proportions of articles, and 95% confidence interval of these proportions with each research design in each journal. We cross-tabulated the clinical areas with research designs (expressed as number and percentages). A total of 1,458 articles from four Brazilian journals were found: Revista Brasileira de Fisioterapia, Revista Fisioterapia em Movimento, Revista Fisioterapia e Pesquisa, and Revista Acta Fisiátrica. The majority of articles were classified as level II of evidence (60%), followed by level III (29%) and level I (10%). The most prevalent research designs were cross-sectional studies (38%), single-case or case-series studies, and narrative reviews. Most articles reported human research and were in the musculoskeletal, neurologic, and cardiothoracic areas. Most of the research published in Brazilian physical therapy journals used levels II and III of evidence. Increasing the publication rate of systematic reviews and randomized controlled trials would provide more high-quality evidence to guide evidence-based physical therapy practice.

Given the American Psychological Association's strong recommendation to always report effect sizes in research, scholars have a responsibility to provide complete information regarding their findings. The purposes of this study were to (a) determine the frequencies with which different effect sizes were reported in published, peer-reviewed articles in health education, promotion, and behavior journals and (b) discuss implications for reporting effect size in social science research. Across a 4-year time period (2010-2013), 1,950 peer-reviewed published articles were examined from the following six health education and behavior journals: American Journal of Health Behavior, American Journal of Health Promotion, Health Education & Behavior, Health Education Research, Journal of American College Health, and Journal of School Health Quantitative features from eligible manuscripts were documented using Qualtrics online survey software. Of the 1,245 articles in the final sample that reported quantitative data analyses, approximately 47.9% (n = 597) of the articles reported an effect size. While 16 unique types of effect size were reported across all included journals, many of the effect sizes were reported with little frequency across most journals. Overall, odds ratio/adjusted odds ratio (n = 340, 50.1%), Pearson r/r(2) (n = 162, 23.8%), and eta squared/partial eta squared (n = 46, 7.2%) accounted for the most frequently used effect size. Quality research practice requires both testing statistical significance and reporting effect size. However, our study shows that a substantial portion of published literature in health education and behavior lacks consistent reporting of effect size. © 2016 Society for Public Health Education.
A Quantitative Analysis and Natural History of B. F. Skinner's Coauthoring Practices
McKerchar, Todd L; Morris, Edward K; Smith, Nathaniel G
2011-01-01
This paper describes and analyzes B. F. Skinner's coauthoring practices. After identifying his 35 coauthored publications and 27 coauthors, we analyze his coauthored works by their form (e.g., journal articles) and kind (e.g., empirical); identify the journals in which he published and their type (e.g., data-type); describe his overall and local rates of publishing with his coauthors (e.g., noting breaks in the latter); and compare his coauthoring practices with his single-authoring practices (e.g., form, kind, journal type) and with those in the scientometric literature (e.g., majority of coauthored publications are empirical). We address these findings in the context of describing the natural history of Skinner's coauthoring practices. Finally, we describe some limitations in our methods and offer suggestions for future research. PMID:22532732
Use of number needed to treat in cost-effectiveness analyses.
Garg, Vishvas; Shen, Xian; Cheng, Yan; Nawarskas, James J; Raisch, Dennis W
2013-03-01
To review the use of number needed to treat (NNT) and/or number needed to harm (NNH) values to determine their relevance in helping clinicians evaluate cost-effectiveness analyses (CEAs). PubMed and EconLit were searched from 1966 to September 2012. Reviews, editorials, non-English-language articles, and articles that did not report NNT/NNH or cost-effectiveness ratios were excluded. CEA studies reporting cost per life-year gained, per quality-adjusted life-year (QALY), or other cost per effectiveness measure were included. Full texts of all included articles were reviewed for study information, including type of journal, impact factor of the journal, focus of study, data source, publication year, how NNT/NNH values were reported, and outcome measures. A total of 188 studies were initially identified, with 69 meeting our inclusion criteria. Most were published in clinician-practice-focused journals (78.3%) while 5.8% were in policy-focused journals, and 15.9% in health-economics-focused journals. The majority (72.4%) of the articles were published in high-impact journals (impact factor >3.0). Many articles focused on either disease treatment (40.5%) or disease prevention (40.5%). Forty-eight percent reported NNT as a part of the CEA ratio per event. Most (53.6%) articles used data from literature reviews, while 24.6% used data from randomized clinical trials, and 20.3% used data from observational studies. In addition, 10% of the studies implemented modeling to perform CEA. CEA studies sometimes include NNT ratios. Although it has several limitations, clinicians often use NNT for decision-making, so including NNT information alongside CEA findings may help clinicians better understand and apply CEA results. Further research is needed to assess how NNT/NNH might meaningfully be incorporated into CEA publications.

In the last 25 years, the number and scope of fish-related journals have changed. New and existing journals are increasingly specialized. Journals that are read and cited are changing because of differential accessibility via electronic databases. In this review, we examine shifts in numbers and foci of existing fish-related journals. We ask how these fish-related metrics differ across type of application, ecological system, taxa, and discipline. Although many journals overlap to some extent in content, there are distinct groups of journals for authors to consider. By systematically reviewing the focus of an individual manuscript, comparing it to the suite of journals available and examining the audience for the manuscript, we believe that authors can make informed decisions about which journals are most suitable for their work. Our goal here is to help authors find relevant journals and deliver scientific publications to the appropriate readership.

In 2005, the Journal of Consulting and Clinical Psychology (JCCP) became the first American Psychological Association (APA) journal to require statistical measures of clinical significance, plus effect sizes (ESs) and associated confidence intervals (CIs), for primary outcomes (La Greca, 2005). As this represents the single largest editorial effort to improve statistical reporting practices in any APA journal in at least a decade, in this article we investigate the efficacy of that change. All intervention studies published in JCCP in 2003, 2004, 2007, and 2008 were reviewed. Each article was coded for method of clinical significance, type of ES, and type of associated CI, broken down by statistical test (F, t, chi-square, r/R(2), and multivariate modeling). By 2008, clinical significance compliance was 75% (up from 31%), with 94% of studies reporting some measure of ES (reporting improved for individual statistical tests ranging from eta(2) = .05 to .17, with reasonable CIs). Reporting of CIs for ESs also improved, although only to 40%. Also, the vast majority of reported CIs used approximations, which become progressively less accurate for smaller sample sizes and larger ESs (cf. Algina & Kessleman, 2003). Changes are near asymptote for ESs and clinical significance, but CIs lag behind. As CIs for ESs are required for primary outcomes, we show how to compute CIs for the vast majority of ESs reported in JCCP, with an example of how to use CIs for ESs as a method to assess clinical significance.

International Orthopaedics was founded in 1977. Within the 40 volumes and 247 issues since its launch, 5462 scientific articles have been published. This article identifies, analyses and categorises the best cited articles published by the journal to date. We searched Elsevier Scopus database for citations of all papers published in International Orthopaedics since its foundation. Source title was selected, and the journal's title was introduced in the search engine. The identified articles were sorted based on their total number of received citations, forming a descending list from 1 to 100. Total citations and self-citations of all co-authors were recorded. Year of publication, number of co-authors, number of pages, country and institution of origin and study type were identified. The best 100 papers and their citations correspond approximately to 2% of all the journal's publications. Total citations ranged from 62 to 272; 26 papers had >100 citations, of which self-citations accounted for <4%. Mean authorship number per paper was four and mean page number 6.5. United States, Japan and Germany ranked the top three countries of origin. The most common study type was case series, and most common topics were adult reconstruction, sports medicine and trauma. This article identifies topics, authors and institutions that contributed with their high-quality work in the journal's development over time. International Orthopaedics remains faithful to its authors and readers by publishing topical, well-written articles in excellent English.
The inclusion of an online journal in PubMed central - a difficult path.
Grech, Victor
2016-01-01
The indexing of a journal in a prominent database (such as PubMed) is an important imprimatur. Journals accepted for inclusion in PubMed Central (PMC) are automatically indexed in PubMed but must provide the entire contents of their publications as XML-tagged (Extensible Markup Language) data files compliant with PubMed's document type definition (DTD). This paper describes the various attempts that the journal Images in Paediatric Cardiology made in its efforts to convert the journal contents (including all of the extant backlog) to PMC-compliant XML for archiving and indexing in PubMed after the journal was accepted for inclusion by the database.
Fake Journals: Their Features and Some Viable Ways to Distinguishing Them.
Hemmat Esfe, Mohammad; Wongwises, Somchai; Asadi, Amin; Akbari, Mohammad
2015-08-01
In this paper, we aim to discuss the fake journals and their advertisement and publication techniques. These types of journals mostly start and continue their activities by using the name of some indexed journals and establishing fake websites. The fake journals and publishers, while asking the authors for a significant amount of money for publishing their papers, have no peer-review process, publish the papers without any revision on the fake sites, and put the scientific reputation and prestige of the researchers in jeopardy. In the rest of the paper, we present some viable techniques in order for researchers and students to identify these journals.

The Malaria in Pregnancy Library: a bibliometric review.
van Eijk, Anna M; Hill, Jenny; Povall, Sue; Reynolds, Alison; Wong, Helen; Ter Kuile, Feiko O
2012-10-30
The Malaria in Pregnancy (MiP) Library is a bibliographic database that was created by the MiP Consortium in 2005 and is updated every four months using a standardized search protocol. A bibliometric review was conducted of the contents of the Library to determine dynamics in the type, content and volume of literature on malaria in pregnancy over time. Data on year of publication, type, language, country of first-author affiliation and content (topic) were extracted from entries in the MiP Library and plotted over time. By January 2012, the MiP Library contained 5,346 entries, consisting of 3,721 journal articles (69.6%), 697 reports (13.0%), 219 academic theses (4.1%), 92 books or book chapters (1.7%), 487 conference proceedings (9.1%), 68 registered studies (1.3%) and 62 'other' (1.2%). Most of the sources were in English language (87.3%), followed by French (7.5%) and Spanish (1.5%). Over 40% of source material was publicly available online (42.4%) and the remaining with restricted access (35.0%) or otherwise unavailable (22.7%). The number of journal articles related to malaria in pregnancy increased from 41 in the 1960s, to 708 in the 1990s, and 1,895 between 2000 and 2009, and the variety of themes has increased over time. English-language articles were sourced from 737 different journals. The top three journals were the American Journal of Tropical Medicine and Hygiene (184), Malaria Journal (158) and the Transactions of the Royal Society of Tropical Medicine and Hygiene (131). The last decade has seen a dramatic increase in publications related to malaria in pregnancy, and an increasing proportion of these are publically available online. The MiP Library is a useful, scholarly source for literature and systematic reviews related to malaria in pregnancy.
Current and potential cyber attacks on medical journals; guidelines for improving security.
Dadkhah, Mehdi; Seno, Seyed Amin Hosseini; Borchardt, Glenn
2017-03-01
At the moment, scholarly publishing is faced with much academic misconduct and threats such as predatory journals, hijacked journals, phishing, and other scams. In response, we have been discussing this misconduct and trying to increase the awareness of researchers, but it seems that there is a lack of research that presents guidelines for editors to help them protect themselves against these threats. It seems that information security is missing in some parts of scholarly publishing that particularly involves medical journals. In this paper, we explain different types of cyber-attacks that especially threaten editors and academic journals. We then explain the details involved in each type of attack. Finally, we present general guidelines for detection and prevention of the attacks. In some cases, we use small experiments to show that our claim is true. Finally, we conclude the paper with a prioritization of these attacks. Copyright © 2016 European Federation of Internal Medicine. Published by Elsevier B.V. All rights reserved.

During the 1950s Australia was one of the world's foremost astronomical nations owing primarily to the work of the dynamic radio astronomy group within the Commonwealth Scientific and Industrial Research Organisation's Division of Radiophysics. Most of the observations were made at the network of field stations maintained by the Division in or near Sydney, and one of these field stations was Murraybank in the north-western suburbs of Sydney.

The validity of studies that assess the effectiveness of an intervention (EoI) depends on variables such as the type of study design, the quality of their methodology, and the participants enrolled. Five leading veterinary journals and 5 leading human medical journals were hand-searched for EoI studies for the year 2013. We assessed (1) the prevalence of randomized controlled trials (RCTs) among EoI studies, (2) the type of participants enrolled, and (3) the methodological quality of the selected studies. Of 1707 eligible articles, 590 were EoI articles and 435 RCTs. Random allocation to the intervention was performed in 52% (114/219; 95%CI:45.2–58.8%) of veterinary EoI articles, against 87% (321/371; 82.5–89.7%) of human EoI articles (adjusted OR:9.2; 3.4–24.8). Veterinary RCTs were smaller (median: 26 animals versus 465 humans) and less likely to enroll real patients, compared with human RCTs (OR:331; 45–2441). Only 2% of the veterinary RCTs, versus 77% of the human RCTs, reported power calculations, primary outcomes, random sequence generation, allocation concealment and estimation methods. Currently, internal and external validity of veterinary EoI studies is limited compared to human medical ones. To address these issues, veterinary interventional research needs to improve its methodology, increase the number of published RCTs and enroll real clinical patients. PMID:26835187

Objective To examine the degree of concordance in reporting serious adverse events (SAEs) from antidepressant and antipsychotic drug trials among journal articles and clinical trial summaries, and to categorise types of discrepancies. Design Cross-sectional study of summaries of all antidepressant and antipsychotic trials included in an online trial registry and their first associated stand-alone journal articles. Setting Clinicalstudyresults.org, sponsored by Pharmaceutical Research and Manufacturers of America; clinicaltrials.gov, administered by the US National Institutes of Health. Main outcome measure 3 coders extracted data on the numbers and types of SAEs. Results 244 trial summaries for six antidepressant and antipsychotic drugs were retrieved, 142 (58.2%) listing an associated article. Of 1608 SAEs in drug-treated participants according to trial summaries, 694 (43.2%) did not appear in associated articles. Nearly 60% of SAEs counted in articles and 41% in trial summaries had no description. Most cases of death (62.3%) and suicide (53.3%) were not reported in articles. Half or more of the 142 pairs were discordant in reporting the number (49.3%) or description (67.6%) of SAEs. These discrepancies resulted from journal articles’ (1) omission of complete SAE data, (2) reporting acute phase study results only and (3) more restrictive reporting criteria. Trial summaries with zero SAE were 2.35 (95% CI, 1.58 to 3.49; p<0.001) times more likely to be published with no discrepancy in their associated journal article. Since clinicalstudyresults.org was removed from the Internet in 2011, only 7.8% of retrieved trial summaries appear with results on clinicaltrials.gov. Conclusions Substantial discrepancies exist in SAE data found in journal articles and registered summaries of antidepressant and antipsychotic drug trials. Two main scientific sources accessible to clinicians and researchers are limited by incomplete, ambiguous and inconsistent reporting. Access to complete and accurate data from clinical trials of drugs currently in use remains a pressing concern. PMID:25009136

Scientific communication knowledge is specifically based in the analysis of the bibliographic references inside the publications. Pattern and laws determining the information consumption in the items of the journal Medicina Clinica are investigated in the present study as its own aim. An analysis was performed on the 13,286 references downloaded from 618 papers published by the journal in 1990. With dBASE IV was generated a database for the management of the information; data was distributed in several tables through criteria of age, documentary types, countries, journals and Bradford zones. The analysed references belong to 1,241 different journals, 110 from Spain. Being two thirds of the total sum, the publications from United States and United Kingdom have received more citations than those from Spain. The publications from european countries, like France, Germany and Italy, are scarcely present. Bradford core is constituted by the journals Medicina Clinica and The Lancet. The analysis of the bibliographic references available from the articles in this journal is able to produce knowledge on the information consumption by the practitioners; its usefulness as a complementary utility to the Indice de Citas e Indicadores Bibliométricos de Revistas Españolas de Medicina Interna y sus especialidades 1990 must be considered.

Purpose: To perform a national survey of radiation oncologists and urologists about the type of resources used and the level of evidence needed to change clinical practice in localized prostate cancer. Methods and Materials: From a random sample, 1422 physicians were mailed a survey assessing the types of information used and what level of evidence could alter their clinical practice in prostate cancer. Multivariable logistic regression models were used to identify differences in physician characteristics for each outcome. Results: Survey response rates were similar for radiation oncologists and urologists (44% vs 46%; P=.46). Specialty-specific journals represented the most commonly usedmore » resource for informing the clinical practice for radiation oncologists (65%) and urologists (70%). Relative to radiation oncologists, urologists were less likely to report utilizing top-tier medical journals (25% vs 39%; adjusted odds ratio [OR] 0.50; P=.01) or cancer journals (22% vs 51%; adjusted OR 0.50; P<.001) but more likely to rely on clinical guidelines (46% vs 38%; adjusted OR 1.6; P=.006). Both radiation oncologists and urologists most commonly reported large randomized, clinical trials as the level of evidence to change treatment recommendations for localized prostate cancer (85% vs 77%; P=.009). Conclusions: Both specialties rely on their own specialty-specific journals and view randomized, clinical trials as the level of evidence needed to change clinical practice. Our study provides a context on meaningful ways of disseminating evidence for localized prostate cancer.« less

Zirconia is a ceramic with material properties ideal for journal bearing applications. The purpose of this study was to evaluate the use of zirconium oxide (zirconia) as a blood journal bearing material in the DexAide right ventricular assist device. Zirconia ceramic was used instead of titanium to manufacture the DexAide stator housing without changing the stator geometry or the remaining pump hardware components. Pump hydraulic performance, journal bearing reliability, biocompatibility, and motor efficiency data of the zirconia stator were evaluated in six chronic bovine experiments for 14-91 days and compared with data from chronic experiments using the titanium stator. Pump performance data including average in vivo pump flows and speeds using a zirconia stator showed no statistically significant difference to the average values for 16 prior titanium stator in vivo studies, with the exception of a 19% reduction in power consumption. Indices of hemolysis were comparable for both stator types. Results of coagulation assays and platelet aggregation tests for the zirconia stator implants showed no device-induced increase in platelet activation. Postexplant evaluation of the zirconia journal bearing surfaces showed no biologic deposition in any of the implants. In conclusion, zirconia ceramic can be used as a hemocompatible material to improve motor efficiency while maintaining hydraulic performance in a blood journal bearing application.
Media coverage of medical journals: do the best articles make the news?
Selvaraj, Senthil; Borkar, Durga S; Prasad, Vinay
2014-01-01
News coverage of medical research is followed closely by many Americans and affects the practice of medicine and influence of scientific research. Prior work has examined the quality of media coverage, but no investigation has characterized the choice of stories covered in a controlled manner. We examined whether the media systematically covers stories of weaker study design. We compared study characteristics of 75 clinically-oriented journal articles that received coverage in the top five newspapers by circulation against 75 clinically-oriented journal articles that appeared in the top five medical journals by impact factor over a similar timespan. Subgroup analysis was performed to determine whether differences between investigations from both sources varied by study type (randomized controlled trial [RCT] or observational study). Investigations receiving coverage from newspapers were less likely to be RCTs (17% vs. 35%, p = 0.016) and more likely to be observational studies (75% vs. 47%, p<0.001). No difference was observed in number of people studied (median: 1034 vs. 1901, p = 0.14) or length of follow-up (median: 1.80 vs. 1.00 years, p = 0.22). In subgroup analysis, observational studies from the media used smaller sample sizes (median: 1984 vs. 21136, p = 0.029) and were more likely to be cross-sectional (71% vs. 31%, p<0.001), while no differences were observed for RCTs. Newspapers were more likely to cover observational studies and less likely to cover RCTs than high impact journals. Additionally, when the media does cover observational studies, they select articles of inferior quality. Newspapers preferentially cover medical research with weaker methodology.
[Use of theories and models on papers of a Latin-American journal in public health, 2000 to 2004].
Cabrera Arana, Gustavo Alonso
2007-12-01
To characterize frequency and type of use of theories or models on papers of a Latin-American journal in public health between 2000 and 2004. The Revista de Saúde Pública was chosen because of its history of periodic publication without interruption and current impact on the scientific communication of the area. A standard procedure was applied for reading and classifying articles in an arbitrary typology of four levels, according to the depth of the use of models or theoretical references to describe problems or issues, to formulate methods and to discuss results. Of 482 articles included, 421 (87%) were research studies, 42 (9%) reviews or special contributions and 19 (4%) opinion texts or assays . Of 421 research studies, 286 (68%) had a quantitative focus, 110 (26%) qualitative and 25 (6%) mixed. Reference to theories or models is uncommon, only 90 (19%) articles mentioned a theory or model. According to the depth of the use, 29 (6%) were classified as type I, 9 (2%) as type II, 6 (1.3%) were type III and the 46 remaining texts (9.5%) were type IV. Reference to models was nine-fold more frequent than the use of theoretical references. The ideal use, type IV, occurred in one of every ten articles studied. It is of relevance to show theoretical and models frames used when approaching topics, formulating hypothesis, designing methods and discussing findings in papers.

Age and aphasia: a review of presence, type, recovery and clinical outcomes.
Ellis, Charles; Urban, Stephanie
2016-12-01
Each year approximately 100,000 stroke survivors are diagnosed with aphasia. Although stroke is associated with age, the relationship between age and aphasia is less clear. To complete a review of the literature to examine the relationship between age and: (a) presence or likelihood of aphasia after stroke, (b) aphasia type, (c) aphasia recovery patterns, and (d) aphasia clinical outcomes. Articles were identified by a comprehensive search of "OneSearch," PubMed, and individual journals: Aphasiology, Stroke and the Journal of Stroke and Cerebrovascular Diseases. Inclusion criteria included: age and incidence of aphasia, likelihood of aphasia, aphasia recovery, and aphasia clinical outcome. Independent searches were completed by the authors. Each author independently assessed the full text of reports meeting inclusion criteria. Differences regarding study eligibility and need to proceed with data extraction were resolved by consensus. 1617 articles were identified during the initial search. Forty studies including 14,795 study participants were included in the review. The review generally demonstrated that: (a) stroke patients with aphasia are typically older than stroke with patients without aphasia and (b) aphasia type and age are associated as younger patients with aphasia are more likely to exhibit non-fluent or Broca's type of aphasia. In contrast, studies examining aphasia recovery and aphasia clinical outcomes did not demonstrate a positive relationship between age and recovery or clinical outcomes. Stroke is a condition of the elderly. However, age appears to only influence likelihood of aphasia and aphasia type.

To determine the accuracy of bibliographic citation in Revista Española de Enfermedades Digestivas (REED) and compare it with other Spanish and international journals. We reviewed all 1995 volumes of the REED and randomly selected 100 references from these volumes. Nine citations of non-journal articles were excluded and the remaining 91 citations were carefully scrutinized. Each original article was compared for author's name, title of article, name of journal, volume number, year of publication and pages. Some type of error was detected in 61.6% of the references and on 3 occasions (3.3%) impeded finding to the original article. Errors were found in authors (37.3%); article title (16.4%), pages (6.6%), journal title (4.4%), volume (2.2%) and year (1%). A single error was found in 42 citations, 2 were found in 13 and 3 were found in 1. REED's rate of error in references is comparable to the rates of other spanish and international journals. Authors should exercise more care in preparing bibliographies and should invest more effort in verification of quoted references.
Radiology journals in transition: a summary of the 2013 Intersociety Committee Summer Conference.
Dodd, Gerald D
2015-01-01
The digital and online revolution is having a profound impact on radiology journals, forcing a migration from print to online publication and altering traditional revenue streams needed to sustain the journals. The 2013 Intersociety Committee Summer Conference attendees reviewed the history of the development of radiology journals, explored the forces driving the transition from print to electronic publication, and examined the impact of the alteration of the traditional revenue streams, such as subscription and advertisement dollars, on the financial sustainability of journals. The attendees also discussed the international movement toward open access to journal content and its impact on a journal's financial viability. Lastly, the committee explored the perceived value of radiology journals based on readership type: academic, private practice, or industry. Copyright © 2015 American College of Radiology.

The requirements of the health policy and services journals for authors to report their financial and non-financial conflicts of interest (COI) are unclear. The present article aims to assess the requirements of health policy and services journals for authors to disclose their financial and non-financial COIs. This is a cross-sectional study of journals listed by the Web of Science under the category of 'Health Policy and Services'. We reviewed the 'Instructions for Authors' on the journals' websites and then simulated the submission of a manuscript to obtain any additional relevant information made available during that step. We abstracted data in duplicate and independently using a standardised form. Out of 72 eligible journals, 67 (93%) had a COI policy. A minority of policies described how the disclosed COIs of authors would impact the editorial process (34%). None of the policies had clear-cut criteria for rejection based on the content of the disclosure. Approximately a fifth of policies (21%) explicitly stated that inaccurate or incomplete disclosures might lead to manuscript rejection or retraction. No policy described whether the journal would verify the accuracy or completeness of authors' disclosed COIs. Most journals' policies (93%) required the disclosure of at least one form of financial COI. While the majority asked for specification of source of payment (71%), a minority asked for the amount (18%). Overall, 81% of policies explicitly required disclosure of non-financial COIs. A majority of health policy and services journal policies required the disclosure of authors' financial and non-financial COIs, but few required details on disclosed COIs. Health policy journals should provide specific definitions and instructions for disclosing non-financial COIs. A framework providing clear typology and operational definitions of the different types of COIs will facilitate both their disclosure by authors and reviewers and their assessment and management by the editorial team and the readers.

Introduction: Nowadays, publishing highly-cited papers is important for researchers and editors. In this evidence-based study, the factors influencing the citability of published papers in the field of medicine have been identified. Material and Methods: 200 papers indexed in Scopus (in two groups: highly-cited and lowly-cited) with 100 papers in each were studied. Needed data were manually collected with a researcher-made checklist. Data analysis was done in SPSS using descriptive and inferential statistics. Results: Variables such as journal IF, journal rank, journal subject quartile, the first/corresponding author’s h-index, the number of documents produced by the first/corresponding author, SJR and SNIP had significantly positive correlation with paper citability (p< .05). Other variables, including among others, paper age, paper type, the number of references, the number of authors, indexing institute and journal kind had not any relationship with paper citability (p> .05). Conclusion: the factors affecting the citability are among indicators relating to authors, publishing journals and published papers. Determining the extent to which these factors influence the citability of a paper needs further large-scaled research. Authors and editors searching for high-citedness should consider these factors when authoring and publishing papers. PMID:29719306

To evaluate the editorial quality, diffusion, relevance of the scientific content, and the publication practices of the specialised journal Revista Española de Enfermedades Digestivas. We checked 136 parameters based on ISO standards, the recommendations of scientific and editorial organisations, and studies of scientific editing and international publishing practices for biomedical journals. Diffusion was calculated using national and international databases, specialised libraries in Spain, and Internet sources. The analysis of the scientific content and publication practices was based on bibliometric indicators for the journal, authorship, and contributions. The sample for this study comprised six alternate issues of volume number 88 (1996), the last issue of this volume, and the first issue of volume 89 (1997). The samples used for the bibliometric analysis varied depending on the characteristics of specific indicators and the availability of information. The overall mean value for compliance with standards was 46.1%, while the real mean was calculated at 72.21%. The editorial procedures at the journal are similar to those of analogous international journals. The Revista Española de Enfermedades Digestivas is included in international databases of biomedical journals, and in the interdisciplinary international database SCI. It was found to be present in 70% of the medical libraries of Spanish universities, and in 73% of the hospital libraries studied. Bibliometric indicators showed co-authorship to be 5.5%; the origin of the authors grouped by province and by type of institutional affiliations showed 27.8% of all authors to be from Madrid, and that more were affiliated with general hospitals than with university hospitals. The mean delay between initial receipt of a manuscript and its publication was 300 days. Cocitation analysis gave the journal a central position amongst the 38 Spanish biomedical journals considered representative of the field. The journal's impact factor for 1996 was 0.260. The Revista Española de Enfermedades Digestivas is a high-quality vehicle of research results, and has acceptable internal editorial procedures. The journal is widely distributed, though its visibility on the Internet should be improved. Co-authorship is similar to that seen in other medical journals. Steps should be taken to make this journal better known within Spain, and to reduce the delay between the initial receipt and the final publication of manuscripts. Its impact factor is increasing steadily.
Methodological reporting of randomized clinical trials in respiratory research in 2010.

Although randomized controlled trials (RCTs) are considered the highest level of evidence, they are also subject to bias, due to a lack of adequately reported randomization, and therefore the reporting should be as explicit as possible for readers to determine the significance of the contents. We evaluated the methodological quality of RCTs in respiratory research in high ranking clinical journals, published in 2010. We assessed the methodological quality, including generation of the allocation sequence, allocation concealment, double-blinding, sample-size calculation, intention-to-treat analysis, flow diagrams, number of medical centers involved, diseases, funding sources, types of interventions, trial registration, number of times the papers have been cited, journal impact factor, journal type, and journal endorsement of the CONSORT (Consolidated Standards of Reporting Trials) rules, in RCTs published in 12 top ranking clinical respiratory journals and 5 top ranking general medical journals. We included 176 trials, of which 93 (53%) reported adequate generation of the allocation sequence, 66 (38%) reported adequate allocation concealment, 79 (45%) were double-blind, 123 (70%) reported adequate sample-size calculation, 88 (50%) reported intention-to-treat analysis, and 122 (69%) included a flow diagram. Multivariate logistic regression analysis revealed that journal impact factor ≥ 5 was the only variable that significantly influenced adequate allocation sequence generation. Trial registration and journal impact factor ≥ 5 significantly influenced adequate allocation concealment. Medical interventions, trial registration, and journal endorsement of the CONSORT statement influenced adequate double-blinding. Publication in one of the general medical journal influenced adequate sample-size calculation. The methodological quality of RCTs in respiratory research needs improvement. Stricter enforcement of the CONSORT statement should enhance the quality of RCTs.
Top 100 Cited Articles in Recent Tobacco Research.
Mahabee-Gittens, E Melinda; Gordon, Judith S; Melink, Katie F; Merianos, Ashley L
2017-01-01
The total citations that a peer-reviewed manuscript has is often used to measure the impact that a publication has in its respective field of study. Both the citation count and total number of publications are often used as measures of academic productivity and success. This issue has been previously investigated in the field of tobacco control research. Given the changing landscape in the field of tobacco research since 2004, we sought to re-examine this issue. The study purpose was to identify the 100 top-cited tobacco-related articles published since 2005, and to categorize and describe the fields of study represented in these articles. We searched the Scopus library database to determine the citations of the top 100 tobacco-related articles. Information was gathered on: title, number of authors, publication year, journal name and impact factor, country of origin, article type and subject category. Articles were selected and analyzed by two independent investigators. We identified the 100 top-cited articles published in 58 journals, led by The New England Journal of Medicine (8) and Lancet (6), between 2005 and 2014. The United States was the most common country of origin for the highly-cited articles. The top article types were observation (27%), basic science (26%), and review articles (24%). The most common article subject area was medicine (74%). A statistically significant association was found between the journal impact factor and the number of top 100 cited articles ( p = 0.03). This review may be helpful to identify articles that may be contributing to the conduct of current and future tobacco research. The analysis can be used as a reference to review and evaluate the publications that are making a high impact in the field of tobacco research.

Weather types in the South Shetlands (Antarctica) were defined using an automated method based on the Lamb Weather Type classification scheme (Jones et al. 1993). This is an objective classification originally developed for the British Isles (Jones et al., 1993) and also applied to southeast (Goodess and Palutikof 1998) and northwest Spain (Lorenzo et al, 2009), Portugal (Trigo and DaCamara 2000) and Greece (Maheras et al. 2004) with good results. Daily atmospheric circulation in the South Shetlands region from 1989 to 2009 was classified using a 16-node grid of sea level pressure data from the ERA Interim. The classification is obtained through the comparison of the magnitudes of the directional and rotational components of the geostrophic flow. Basic circulation types were combined into 10 groups of weather types: four directional types (NW, N, S and SW), three anticyclonic types (A, ASW and ANW), and three cyclonic types (C, CSW and CNW). Westerly flow and cyclonic circulation are the most frequent events throughout the year. The sea level pressure field for each weather type is presented and the synoptic characteristics are described. The analysis is based on ERA-Interim fields, including mean sea level pressure, precipitation, cloud cover, humidity and air temperature. Snow thickess modelled using HTESSEL is also considered. Analysis of variance (anova) and multivariate analysis (principal component analysis) are applied to evaluate the characteristics of each weather type. This circulation-type approach showed good results in the past for the downscaling of precipitation in other regions, and we are interested in evaluating the possibilities that the classification offers for downscaling precipitation, but also for snow and air temperature. For this we will be using observational data at test sites in Livingston and Deception islands. We are also motivated by the possibility of using the circulation-type approach as a predictor in statistical downscaling. References: Goodess CM, Palutikof JP.1998.

Disclosures of Conflicts of Interest in Psychiatric Review Articles
Kopelman, Andrew M.; Gorelick, David A.; Appelbaum, Paul S.
2013-01-01
To characterize disclosures of conflicts of interest in review articles in psychiatry, we identified 285 reviews from ten high-impact journals in psychiatry and two in general medicine. Disclosures were reliably coded as biotech/pharmaceutical/other material interests, nonprofit/government, communication companies, or other. Authors in both types of journals frequently reported industry ties. However, reviews in psychiatric journals were significantly less likely to include industry-related disclosures (32% of reviews; 18% of authors) compared with general medical journals (64% of articles; 40% of authors). The most common types of industry-related disclosures were for consulting, research support, and speaking fees. Disclosures appeared to be of limited utility in helping readers assess possible biases, because the nature and extent of the relationship being disclosed was often unclear. Efforts to screen out authors with significant financial relationships pertaining to the topic under review may be more effective than disclosure in protecting the integrity of the medical literature.

Economic Evaluation in Global Perspective: A Bibliometric Analysis of the Recent Literature.
Pitt, Catherine; Goodman, Catherine; Hanson, Kara
2016-02-01
We present a bibliometric analysis of recently published full economic evaluations of health interventions and reflect critically on the implications of our findings for this growing field. We created a database drawing on 14 health, economic, and/or general literature databases for articles published between 1 January 2012 and 3 May 2014 and identified 2844 economic evaluations meeting our criteria. We present findings regarding the sensitivity, specificity, and added value of searches in the different databases. We examine the distribution of publications between countries, regions, and health areas studied and compare the relative volume of research with disease burden. We analyse authors' country and institutional affiliations, journals and journal type, language, and type of economic evaluation conducted. More than 1200 economic evaluations were published annually, of which 4% addressed low-income countries, 4% lower-middle-income countries, 14% upper-middle-income countries, and 83% high-income countries. Across country income levels, 53, 54, 86, and 100% of articles, respectively, included an author based in a country within the income level studied. Biomedical journals published 74% of economic evaluations. The volume of research across health areas correlates more closely with disease burden in high-income than in low-income and middle-income countries. Our findings provide an empirical basis for further study on methods, research prioritization, and capacity development in health economic evaluation. © 2016 The Authors.

Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.
Authorship policies of scientific journals.
Resnik, David B; Tyler, Ana M; Black, Jennifer R; Kissling, Grace
2016-03-01
We analysed the authorship policies of a random sample of 600 journals from the Journal Citation Reports database. 62.5% of the journals we sampled had an authorship policy. Having an authorship policy was positively associated with impact factor. Journals from the biomedical sciences and social sciences/humanities were more likely to have an authorship policy than journals from the physical sciences, engineering or mathematical sciences. Among journals with a policy, the most frequent type of policy was guidance on criteria for authorship (99.7%); followed by guidance on acknowledgments (97.3%); requiring that authors make substantial contributions to the research (94.7%); requiring that authors be accountable for the research as a whole (84.8%); guidance on changes in authorship (77.9%); requiring that authors give final approval to the manuscript (77.6%); requiring that authors draft or critically revise the manuscript (71.7%); providing guidance on corporate authorship (58.9%); prohibiting gift, guest or ghost authorship (31.7%); requiring authors to describe their contributions (5.3%); limiting the number of authors for some types of articles (4.0%) and requiring authors to be accountable for their part in the research (1.1%). None of the policies addressed equal contribution statements. Journals that do not have authorship policies should consider adopting or developing ones. Published by the BMJ Publishing Group Limited.

[Authorship and data reporting according to gender in four Spanish biomedical journals].
Schiaffino, A; García, M; Fernández, E
2001-01-01
To describe authorship according to gender in the articles published in four Spanish scientific journals of general medicine and public health, and to analyse the type of presentation of the results in relation to the sex of the subjects of the study. We examined 423 articles from four Spanish scientific journals published during 1998. 70.7% of the articles revised had a man as the first author. The sex difference was significant in the editorials (12.4% of the women vs. 29.8% of the men, p < 0.05). Stratification of the results by sex was presented in 167 articles and in 85.6% of them the information about men. Gender inequalities in the publication of scientific works in the field of general medicine and public health are found.

Clinical assignments in nursing education provide opportunities for students to develop thinking skills vital to the effective delivery of patient care. The purpose of the present study was to examine students' perceived levels of confidence for using thinking skills when completing two types of clinical assignments. Clinical educators and managers are challenged to develop teaching and learning strategies that help students think critically and reflectively and transfer these skills into sound nursing practice. This study is based on the theoretical framework of critical thinking within the nursing process framework. Undergraduate nursing students (n=51) completed surveys indicating their confidence in using seven thinking skills for nursing care. Students indicated significantly more confidence when implementing the journal format as compared with the care plan format when analysing information, determining relevance, making connections, selecting appropriate information, applying relevant knowledge and evaluating outcomes. The findings of the present study propose a new approach for enhancing students' thinking skills. Journaling is an effective strategy for enhancing students' thinking skills. Nursing managers are in key organisational positions for supporting and promoting the use of the journal format and building supportive and collaborative learning environments for students to develop thinking skills for managing patient care. © 2010 The Authors.

To describe and analyze the general characteristics and methodology of indexed publications by the health staff of the Mexican Social Security Institute in 1997. Original articles were evaluated. The primary sources included Index Medicus, Current Contents and the Mexican National Council of Science and Technology (CONACYT) index. The following information was gathered for each article: affiliation and chief activity of the first author; impact factor of the journal; research type; field of study; topic of study, and methodological conduction. This latter point included congruence between design and objective, reproducibility of methods, applicability of the analysis, and pertinence of the conclusions. A total of 300 original articles was published of which 212 (71%) were available for the present study: full-time investigators (FTI) generated 109 articles and investigators with clinical activities (CAI) wrote 103 articles. The median impact factor of the journals in which FTI published was 1.337 (0.341 to 37.297) and for CAI publications, 0.707 (0.400 to 4.237). Biomedical research predominated in the first group (41%) and clinical investigation in the second (66%). Statistically significant differences were identified for the methodological conduction between groups of investigators. Descriptive studies and publications in journals without impact factor predominated. The FTI group had the highest bibliographic production of original articles in indexed journals with an impact factor.

To evaluate the disparity in authorship based on gender and nationality of institutional affiliation among journals from developed and developing countries. Original articles from two neuroscience journals, with a 5 year impact factor >15 (Neuron and Nature Neuroscience) and from two neurology journals from a developing country (Neurology India and Annals of Indian Academy of Neurology) were categorized by gender and institutional affiliation of first and senior authors. Articles were further divided by the type of research (basic/translational/clinical), study/target population (adult/pediatrics/both) and field of neurology. Data was collected for the years 2002 and 2012. There are large disparities in authorship by women and from developing countries in high impact factor neuroscience journals. However, there was a non-statistical rise in female first and senior authorship over a 10 year period. Additionally there was a significant increase in first authorship from institutions based in developing countries in the two neuroscience journals examined (P < 0.05). In the two neurology journals based in India there was a significant increase in the number of articles published by international investigators between 2002 and 2012 (P < 0.05). Over the last decade, there has been a non-statistical increase in proportion of female first and senior authors, and a significant increase in authors from developing countries in high impact factor neuroscience journals. However they continue to constitute a minority. The disparity in authorship based on gender also exists in neurology journals based in a developing country (India).

To analyse systematic review articles published in the top 10 nursing journals to determine the quality of the methods employed within them. Systematic review is defined as a scientific research method that synthesises high-quality scientific knowledge on a given topic. The number of such reviews in nursing science has increased dramatically during recent years, but their methodological quality has not previously been assessed. A review of the literature using a narrative approach. Ranked impact factor scores for nursing journals were obtained from the Journal Citation Report database of the Institute of Scientific Information (ISI Web of Knowledge). All issues from the years 2009 and 2010 of the top 10 ranked journals were included. CINAHL and MEDLINE databases were searched to locate studies using the search terms 'systematic review' and 'systematic literature review'. A total of 39 eligible studies were identified. Their methodological quality was evaluated through the specific criteria of quality assessment, description of synthesis and strengths and weaknesses reported in the included studies. Most of the eligible systematic reviews included several different designs or types of quantitative study. The majority included a quality assessment, and a total of 17 different criteria were identified. The method of synthesis was mentioned in about half of the reviews, the most common being narrative synthesis. The weaknesses of reviews were discussed, while strengths were rarely highlighted. The methodological quality of the systematic reviews examined varied considerably, although they were all published in nursing journals with a high-impact factor. Despite the fact that systematic reviews are considered the most robust source of research evidence, they vary in methodological quality. This point is important to consider in clinical practice when applying the results to patient care. © 2013 Blackwell Publishing Ltd.
Where to publish? Some considerations among English-language addiction journals.
Arciniega, L T; Miller, W R
1997-12-01
A search and survey of specialty periodicals in the addiction field identified 35 English-language scientific journals that publish unsolicited research manuscripts. Among these, the typical addiction journal publishes a variety of types of articles in one of many different citation and referencing formats, releases four issues per year to about 1000 subscribers, annually receives more than 100 manuscripts for scientific review, and accepts 53 of them to be published without payment of an author fee. Together these 35 addiction journals publish over 1700 new articles each year. Addiction journals vary widely in acceptance rates, ranging from 26% to 95%, and averaging 53%. For better or worse, these journals offer ample opportunity for the reporting of scientific data in the addiction field.

The aim of this study was to evaluate and analyze the evolving trends in endodontic research in 2 leading endodontic journals (ie, Journal of Endodontics and International Endodontic Journal) in articles published from January 2009 to December 2013. The differences in content between this period and a 10-year earlier period from January 1999 to December 2003 were also evaluated. Each journal's content was accessed through the web edition. For each article, the following parameters were recorded: number of authors, article type, number of affiliations, field of study, source of article, and geographic origin. The recorded data were analyzed using both descriptive and analytic statistics. During 2009-2013 (second period), the mean number of authors per article increased significantly compared with 1999-2003 (first period). The main volume of the literature in both periods and journals was original research articles. The number of published reviews increased significantly from the first to the second study period in contrast to case reports/clinical articles, which presented a significant decrease. "Endodontic materials" was the most prevalent thematic category in both study periods. The number of published articles related to "biology" and "chemical preparation and disinfection" increased significantly from the first to the second study period. On the contrary, the number of articles regarding "obturation and microleakage" presented a considerable decrease at the same time. The United States was the leading country in the number of publications in the first period followed by Brazil. In the second period, this rank was reversed with Brazil becoming the leading country followed by the United States. In the last 15 years, the progress of the specialty of endodontology was apparent as shown through the trends and shifts in research orientation in published articles in the 2 leading endodontic journals. The results of the present reviewing process encourage both journals to publish well-designed research projects with a high degree of difficulty, thus contributing to a more evidence-based approach of endodontology.

Qualitative environmental health research: an analysis of the literature, 1991-2008.
Scammell, Madeleine Kangsen
2010-08-01
Recent articles have advocated for the use of qualitative methods in environmental health research. Qualitative research uses nonnumeric data to understand people's opinions, motives, understanding, and beliefs about events or phenomena. In this analysis of the literature, I report the use of qualitative methods and data in the study of the relationship between environmental exposures and human health. A primary search on ISI Web of Knowledge/Web of Science for peer-reviewed journal articles dated from 1991 through 2008 included the following three terms: qualitative, environ*, and health. Inclusion and exclusion criteria are described. Searches resulted in 3,155 records. Data were extracted and findings of articles analyzed to determine where and by whom qualitative environmental health research is conducted and published, the types of methods and analyses used in qualitative studies of environmental health, and the types of information qualitative data contribute to environmental health. Ninety-one articles met inclusion criteria. These articles were published in 58 different journals, with a maximum of eight for a single journal. The results highlight a diversity of disciplines and techniques among researchers who used qualitative methods to study environmental health, with most studies relying on one-on-one interviews. Details of the analyses were absent from a large number of studies. Nearly all of the studies identified increased scientific understanding of lay perceptions of environmental health exposures. Qualitative data are published in traditionally quantitative environmental health studies to a limited extent. However, this analysis demonstrates the potential of qualitative data to improve understanding of complex exposure pathways, including the influence of social factors on environmental health, and health outcomes.
Media Coverage of Medical Journals: Do the Best Articles Make the News?
Selvaraj, Senthil; Borkar, Durga S.; Prasad, Vinay
2014-01-01
Background News coverage of medical research is followed closely by many Americans and affects the practice of medicine and influence of scientific research. Prior work has examined the quality of media coverage, but no investigation has characterized the choice of stories covered in a controlled manner. We examined whether the media systematically covers stories of weaker study design. Methods We compared study characteristics of 75 clinically-oriented journal articles that received coverage in the top five newspapers by circulation against 75 clinically-oriented journal articles that appeared in the top five medical journals by impact factor over a similar timespan. Subgroup analysis was performed to determine whether differences between investigations from both sources varied by study type (randomized controlled trial [RCT] or observational study). Results Investigations receiving coverage from newspapers were less likely to be RCTs (17% vs. 35%, p = 0.016) and more likely to be observational studies (75% vs. 47%, p<0.001). No difference was observed in number of people studied (median: 1034 vs. 1901, p = 0.14) or length of follow-up (median: 1.80 vs. 1.00 years, p = 0.22). In subgroup analysis, observational studies from the media used smaller sample sizes (median: 1984 vs. 21136, p = 0.029) and were more likely to be cross-sectional (71% vs. 31%, p<0.001), while no differences were observed for RCTs. Conclusions Newspapers were more likely to cover observational studies and less likely to cover RCTs than high impact journals. Additionally, when the media does cover observational studies, they select articles of inferior quality. Newspapers preferentially cover medical research with weaker methodology. PMID:24465543

Full-text searches of articles increase the recall, defined by the proportion of relevant publications that are retrieved. However, this method is rarely used in medical research due to resource constraints. For the purpose of a systematic review of publications addressing shared decision making, a full-text search method was required to retrieve publications where shared decision making does not appear in the title or abstract. The objective of our study was to assess the efficiency and reliability of full-text searches in major medical journals for identifying shared decision making publications. A full-text search was performed on the websites of 15 high-impact journals in general internal medicine to look up publications of any type from 1996-2011 containing the phrase "shared decision making". The search method was compared with a PubMed search of titles and abstracts only. The full-text search was further validated by requesting all publications from the same time period from the individual journal publishers and searching through the collected dataset. The full-text search for "shared decision making" on journal websites identified 1286 publications in 15 journals compared to 119 through the PubMed search. The search within the publisher-provided publications of 6 journals identified 613 publications compared to 646 with the full-text search on the respective journal websites. The concordance rate was 94.3% between both full-text searches. Full-text searching on medical journal websites is an efficient and reliable way to identify relevant articles in the field of shared decision making for review or other purposes. It may be more widely used in biomedical research in other fields in the future, with the collaboration of publishers and journals toward open-access data.

The purpose of our study was to identify and characterize the 100 most-cited articles in neuroimaging. Based on the database of Journal Citation Reports, we selected 669 journals that were considered as potential outlets for neuroimaging articles. The Web of Science search tools were used to identify the 100 most-cited articles relevant to neuroimaging within the selected journals. The following information was recorded for each article: publication year, journal, category and impact factor of journal, number of citations, number of annual citations, authorship, department, institution, country, article type, imaging technique used, and topic. The 100 most-cited articles in neuroimaging were published between 1980 and 2012, with 1995-2004 producing 69 articles. Citations ranged from 4384 to 673 and annual citations ranged from 313.1 to 24.9. The majority of articles were published in radiology/imaging journals (n=75), originated in the United States (n=58), were original articles (n=63), used MRI as imaging modality (n=85), and dealt with imaging technique (n=45). The Oxford Centre for Functional Magnetic Resonance Imaging of the Brain at John Radcliffe Hospital (n=10) was the leading institutions and Karl J. Friston (n=11) was the most prolific author. Our study presents a detailed list and an analysis of the 100 most-cited articles in the field of neuroimaging, which provides an insight into historical developments and allows for recognition of the important advances in this field.

Choi, Eunsil; Lyu, Jiyoung; Park, Jinyoung; Kim, Hae-Young
2014-12-01
The purposes of this study were to assess the trend of use of statistical methods including parametric and nonparametric methods and to evaluate the use of complex statistical methodology in recent periodontal studies. This study analyzed 123 articles published in the Journal of Periodontal & Implant Science (JPIS) between 2010 and 2014. Frequencies and percentages were calculated according to the number of statistical methods used, the type of statistical method applied, and the type of statistical software used. Most of the published articles considered (64.4%) used statistical methods. Since 2011, the percentage of JPIS articles using statistics has increased. On the basis of multiple counting, we found that the percentage of studies in JPIS using parametric methods was 61.1%. Further, complex statistical methods were applied in only 6 of the published studies (5.0%), and nonparametric statistical methods were applied in 77 of the published studies (38.9% of a total of 198 studies considered). We found an increasing trend towards the application of statistical methods and nonparametric methods in recent periodontal studies and thus, concluded that increased use of complex statistical methodology might be preferred by the researchers in the fields of study covered by JPIS.

A Mixed Methods Content Analysis of the Research Literature in Science Education
NASA Astrophysics Data System (ADS)
Schram, Asta B.
2014-10-01
In recent years, more and more researchers in science education have been turning to the practice of combining qualitative and quantitative methods in the same study. This approach of using mixed methods creates possibilities to study the various issues that science educators encounter in more depth. In this content analysis, I evaluated 18 studies from science education journals as they relate to the definition, design, and overall practice of using mixed methods. I scrutinized a purposeful sample, derived from 3 journals (the International Journal of Science Education, the Journal of Research in Science Teaching, and the Research in Science Education) in terms of the type of data collected, timing, priority, design, the mixing of the 2 data strands in the studies, and the justifications authors provide for using mixed methods. Furthermore, the articles were evaluated in terms of how well they met contemporary definitions for mixed methods research. The studies varied considerably in the use and understanding of mixed methods. A systematic evaluation of the employment of mixed methods methodology was used to identify the studies that best reflected contemporary definitions. A comparison to earlier content analyses of mixed methods research indicates that researchers' knowledge of mixed methods methodology may be increasing. The use of this strategy in science education research calls, however, for an improved methodology, especially concerning the practice of mixing. Suggestions are given on how to best use this approach.

Background Quantitative survey of research articles, as an application of bibliometrics, is an effective tool for grasping overall trends in various medical research fields. This type of survey has been also applied to infectious disease research; however, previous studies were insufficient as they underestimated articles published in non-English or regional journals. Methods Using a combination of Scopus™ and PubMed, the databases of scientific literature, and English and non-English keywords directly linked to infectious disease control, we identified international and regional infectious disease journals. In order to ascertain whether the newly selected journals were appropriate to survey a wide range of research articles, we compared the number of original articles and reviews registered in the selected journals to those in the 'Infectious Disease Category' of the Science Citation Index Expanded™ (SCI Infectious Disease Category) during 1998-2006. Subsequently, we applied the newly selected journals to survey the number of original articles and reviews originating from 11 Asian countries during the same period. Results One hundred journals, written in English or 7 non-English languages, were newly selected as infectious disease journals. The journals published 14,156 original articles and reviews of Asian origin and 118,158 throughout the world, more than those registered in the SCI Infectious Disease Category (4,621 of Asian origin and 66,518 of the world in the category). In Asian trend analysis of the 100 journals, Japan had the highest percentage of original articles and reviews in the area, and no noticeable increase in articles was revealed during the study period. China, India and Taiwan had relatively large numbers and a high increase rate of original articles among Asian countries. When adjusting the publication of original articles according to the country population and the gross domestic product (GDP), Singapore and Taiwan were the most productive. Conclusion A survey of 100 selected journals is more sensitive than the SCI Infectious Disease Category from the viewpoint of avoiding underestimating the number of infectious disease research articles of Asian origin. The survey method is applicable to grasp global trends in disease research, although the method may require further development. PMID:19804650

Despite a dramatic influx of female dermatologists during the last 30 years, women in academic dermatology departments remain relatively clustered in junior faculty positions. Research in other specialties showing a disparity in the academic productivity of women has led to many hypotheses regarding factors that may place them at a competitive disadvantage. It is unknown, however, whether similar differences in academic productivity might also serve as barriers to advancement in dermatology, or whether any productivity gap actually exists in this specialty that experienced a more substantial entry of women. Because publication in peer-reviewed journals is one of the core measures of academic productivity used in the promotion process, we evaluated trends in the prevalence of female authorship in top dermatology journals during the last 3 decades. We conducted an observational study of trends in the sex distribution of US authors in 3 prestigious general dermatology journals (in 1976, 1986, 1996, and 2006) and 3 subspecialty dermatology journals (in 2006 only). Journals were chosen based on published impact factors and citation half-lives. During the last 3 decades, the proportion of women authoring manuscripts in the 3 major general dermatology journals increased from 12% to 48% of US-affiliated first authors (P < .001) and from 6.2% to 31% of US-affiliated senior authors (P < .001). Separate analyses by journal and by article type showed similar increases. The prevalence of female authors in subspecialty journals in 2006 was slightly more variable. Although the publications selected for this study capture many of the most respected US journals in dermatology, they may not be representative of all journals in which dermatologists publish. Female dermatologists are authoring publications in growing numbers that match or exceed their prevalence in the academic and overall workforce. This suggests that other factors (differences in productivity outside of the publishing arena, differences in job descriptions or opportunities, differences in career aspirations, a lack of institutional support or flexibility, or gender bias) may be associated with the ongoing reduced advancement of women to senior academic dermatology ranks relative to their male colleagues, and further research is warranted to explore these possibilities.

The purpose of this investigation is to determine the proportion of sports medicine studies that are labeled as Level I Evidence in 5 journals and compare the quality of surgical and nonsurgical studies using simple quality assessment tools (Consolidated Standards of Reporting Trials [CONSORT] and Jadad). By use of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines over the prior 2 years in the top 5 (citation and impact factor based) sports medicine journals, only Level I Evidence studies were eligible for inclusion and were analyzed. All study types (therapeutic, prognostic, diagnostic, and economic) were analyzed. Study quality was assessed with the level of evidence, Jadad score, and CONSORT 2010 guidelines. Study demographic data were compared among journals and between surgical and nonsurgical studies by use of χ(2), 1-way analysis of variance, and 2-sample Z tests. We analyzed 190 Level I Evidence studies (10% of eligible studies) (119 randomized controlled trials [RCTs]). Therapeutic, nonsurgical, single-center studies from the United States were the most common studies published. Sixty-two percent of studies reported a financial conflict of interest. The knee was the most common body part studied, and track-and-field/endurance sports were the most common sports analyzed. Significant differences (P < .05) were shown in Jadad and CONSORT scores among the journals reviewed. Overall, the Jadad and CONSORT scores were 2.71 and 77%, respectively. No differences (P > .05) were shown among journals based on the proportion of Level I studies or appropriate randomization. Significant strengths and limitations of RCTs were identified. This study showed that Level I Evidence and RCTs comprise 10% and 6% of contemporary sports medicine literature, respectively. Therapeutic, nonsurgical, single-center studies are the most common publications with Level I Evidence. Significant differences across sports medicine journals were found in study quality. Surgical studies appropriately described randomization, blinding, and patient enrollment significantly more than nonsurgical studies. Level I, systematic review of Level I studies.

The aim of this study is to systematically evaluate the theses in the field of emergency medicine in Turkey and to determine whether they were published as a scientific paper. This is a retrospective observational study. Theses in the field of emergency medicine between 1998 and 2013 were browsed from the internet database of National Thesis Center (Council of Higher Education). Study type, both if it was in the field of emergency, or if it was published and the journal's scope of published studies were assessed and recorded in the study chart. 579 theses were included in the study. 27.1% of them were published and 14.9% of them were published in SCI/SCI-E journals. Advisors of theses were emergency medicine specialists in 67.6% of theses and 493 (85.1%) of them were in the field of emergency medicine. 77.4% of theses were observational and 20.9% were experimental study. Most of the experimental studies (72.7%, n=88) were animal studies. It was concluded that very few theses in the field of emergency medicine were published in journals that were indexed in SCI/SCI-E.
Increasing value and reducing waste: addressing inaccessible research

The study protocol, publications, full study report detailing all analyses, and participant-level dataset constitute the main documentation of methods and results for health research. However, journal publications are available for only half of all studies and are plagued by selective reporting of methods and results. The protocol, full study report, and participant-level dataset are rarely available. The quality of information provided in study protocols and reports is variable and often incomplete. Inaccessibility of full information for the vast majority of studies wastes billions of dollars, introduces bias, and has a detrimental impact on patient care and research. To help improve this situation at a systemic level, three main actions are warranted. Firstly, it is important that academic institutions and funders reward investigators who fully disseminate their research protocols, reports, and participant-level datasets. Secondly, standards for the content of protocols, full study reports, and data sharing practices should be rigorously developed and adopted for all types of health research. Finally, journals, funders, sponsors, research ethics committees, regulators, and legislators should implement and enforce policies supporting study registration and availability of journal publications, full study reports, and participant-level datasets.

Objective: Bibliometric techniques were used to analyze the citation patterns of researchers publishing in the American Journal of Veterinary Research (AJVR). Methods: The more than 25,000 bibliographic references appearing in the AJVR from 2001 to 2003 were examined for material type, date of publication, and frequency of journals cited. Journal titles were ranked in decreasing order of productivity to create a core list of journals most frequently used by veterinary medical researchers. Results: The majority of items cited were journals (88.8%), followed by books (9.8%) and gray literature (2.1%). Current sources of information were favored; 65% of the journals and 77% of the books were published in 1990 or later. Dividing the cited articles into 3 even zones revealed that 24 journals produced 7,361 cited articles in the first zone. One hundred thirty-nine journals were responsible for 7,414 cited articles in zone 2, and 1,409 journals produced 7,422 cited articles in zone 3. Conclusions: A core collection of veterinary medicine journals would include 49 veterinary medicine journals from zones 1 and 2. Libraries supporting a veterinary curriculum or veterinary research should also include veterinary medical journals from Zone 3, as well as provide access to journals in non-veterinary subjects such as biochemistry, virology, orthopedics, and surgery and a selection of general science and medical journals.

Mapping the literature of pediatric nursing.
Taylor, Mary K
2006-04-01
Pediatric nurses work in an interdisciplinary field and face ever-increasing demands on their time and knowledge. Selection tools for librarians serving this group are available, but only one bibliometric analysis has examined citations to aid collection development. The "Mapping the Literature of Nursing Project" protocol was used. Three source journals were selected, and a citation analysis of articles from 1998 to 2000 was conducted. The frequency of journal citation was tabulated, and a list of the most frequently cited journals was created. Just over 1% of the cited journals produced 33% of the citations. PubMed/MEDLINE, Science Citation Index, and Social Sciences Citation Index provided the most complete indexing coverage of all types of the journals, while CINAHL providing the most complete coverage of nursing journals. Books were the second-most frequently cited format. Citation analysis of journal articles from pediatric nursing journals may be helpful in selecting journals for libraries serving pediatric nurses and those who conduct pediatric nursing research. Librarians should consider adding indexes to their collection in addition to PubMed/MEDLINE to access the broad range of journals useful to this specialty.

Although the peer review process is believed to ensure scientific rigor, enhance research quality, and improve manuscript clarity, many investigators are concerned that the process is too slow, too expensive, too unreliable, and too static. In this feasibility study, we sought to survey corresponding authors of recently published clinical research studies on the speed and efficiency of the publication process. Web-based survey of corresponding authors of a 20% random sample of clinical research studies in MEDLINE-indexed journals with Ovid MEDLINE entry dates between December 1 and 15, 2016. Survey addressed perceived manuscript importance before first submission, approximate first submission and final acceptance dates, and total number of journal submissions, external peer reviews, external peer reviewers, and revisions requested, as well as whether authors would have considered publicly sharing their manuscript on an online platform instead of submitting to a peer-reviewed journal. Of 1780 surveys distributed, 27 corresponding authors opted out or requested that we stop emailing them and 149 emails failed (e.g., emails that bounced n = 64, returned with an away from office message n = 70, or were changed/incorrect n = 15), leaving 1604 respondents, of which 337 completed the survey (21.0%). Respondents and non-respondents were similar with respect to study type and publication journals' impact factor, although non-respondent authors had more publications ( p = 0.03). Among respondents, the median impact factor of the publications' journal was 2.7 (interquartile range (IQR), 2.0-3.6) and corresponding authors' median h-index and number of publications was 9 (IQR, 3-20) and 27 (IQR, 10-77), respectively. The median time from first submission to journal acceptance and publication was 5 months (IQR, 3-8) and 7 months (IQR, 5-12), respectively. Most respondents (62.0%, n = 209) rated the importance of their research as a 4 or 5 (5-point scale) prior to submission. Median number of journal submissions was 1 (IQR, 1-2), external peer reviews was 1 (IQR, 1-2), external peer reviewers was 3 (IQR, 2-4), and revisions requested was 1 (IQR, 1-1). Sharing manuscripts to a public online platform, instead of submitting to a peer-reviewed journal, would have been considered by 55.2% ( n = 186) of respondents. Corresponding authors have high perceptions of their research and reported requiring few manuscript submissions prior to journal acceptance, most commonly by lower impact factor journals.

This study conducted a series of content analyses of the articles published by International Journal of Science Education, Science Education, and Journal of Research in Science Teaching from 1998 to 2002. A total of 802 research papers were analyzed in terms of the authors' nationality, research types and topics. It was found that researchers in four major English-speaking countries, including the US, the UK, Australia, and Canada, contributed to a majority of the publications, but the researchers from other non-English countries may have, to a certain extent, gradually played a valuable role on the published work. This probably implies that science education research may have progressively become an important field recognized by the international academic community. This study also found that most of the published articles were categorized as empirical studies, while position, theoretical and review papers were rarely presented in the journals. Although the research topic of students' conceptions and conceptual change was the most frequently investigated one in these five years, a declining trend was observed when analyzed by year. Moreover, in 1998-2002, the research topics related to student learning contexts, and social, cultural and gender issues were also received relatively more attention among science educators.

Although bibliometric analysis affords significant insight into the progression and distribution of information within a particular research field, detailed longitudinal studies of this type are rare within the field of nursing. This study aimed to investigate, from a bibliometric perspective, the progression and trends of core international nursing journals over the longest possible time period. A detailed bibliometric analysis was undertaken among 7 core international nursing periodicals using custom historical data sourced from the Thomson Reuters Journal Citation Reports®. In the 32 years between 1977 and 2008, the number of citations received by these 7 journals increased over 700%. A sustained and statistically significant (p<0.001) 3-fold increase was also observed in the average impact factor score during this period. Statistical analysis revealed that all periodicals experienced significant (p<0.001) improvements in their impact factors over time, with gains ranging from approximately 2- to 78-fold. Overall, this study provides one of the most comprehensive, longitudinal bibliometric analyses ever conducted in the field of nursing. Impressive and continual impact factor gains suggest that published nursing research is being increasingly seen, heard and cited in the international academic community.

To analyze the current research status of rehabilitation nursing for adult burn patients in China, and to disuss the related strategies. Chinese scientific articles on adult burn patients' rehabilitation nursing published from January 2003 to December 2013 were retrieved from 3 databases namely China Biology Medicine disc, Chinese Journals Full-text Database , and Chinese Science and Technology Journals Database . From the results retrieved, data with regard to publication year, journal distribution, research type, region of affiliation of the first author, and the main research content were collected. Data were processed with Microsoft Excel software. A total of 417 articles conforming with the criteria were retrieved. During the 11 years, the number of the relevant articles per year was on the rise, and the increasing rates in 2005, 2008, 2009, and 2013 were all above 30% . Regarding the distribution among journals, these 417 articles were published in 151 journals, with 188 articles in Source Journal for Chinese Scientific and Technical Papers , accounting for 45.08%. Regarding the research type, 173 out of the 417 articles were dealing with clinical experiences, accounting for 41.49% ; 172 out of the 417 articles were dealing with experimental studies, accounting for 41.25% . The regions of affiliation of the first author were mainly situated in Guangdong province, Shandong province, Hunan province, and Jiangsu province, with Guangdong province contributing 58 articles, accounting for 13.91%. The research content of these articles was mainly focused on psychological nursing, nursing model, and health education, respectively 188,101, and 85 articles, accounting for 45.08%, 24.22%, and 20.38%. The research on rehabilitation nursing for adult burn patients in China has been carried out nationwide. Although the number of relevant papers is on the rise, the quality of these papers needs to be further improved. There is an urgent need for the guideline on rehabilitation nursing for adult burn patients in China so as to standardize the content and procedure of rehabilitation nursing.
[Reviewing an article for Radiología: who and how].

The reviewer's job is fundamental to the editorial process in a scientific journal. The quality of the review will determine the quality of the journal. Therefore, it is very important for the reviewers to make this mission their own and to contribute to the development of science and of the journal. On the other hand, the focus of a review will depend largely on the type of journal for which one is reviewing. In this article, we explain what the journal Radiología, the scientific journal of the Spanish Society of Medical Radiology, expects of its reviewers and their reviews of original articles. We aim to establish some basic rules to lay the groundwork for the development of more detailed guidelines for reviewing articles for the journal Radiología. Copyright © 2011 SERAM.

Among the iconic mammals of the North American West is the mule deer (Odocoileus hemionus). This species and a western subspecies of the white-tailed deer (Odocoileus virginianus macrourus) were two of seven mammals originally named and described as new species in 1817 by Constantine S. Rafinesque. Rafinesque never saw the animals that he named. Instead, he followed the then-acceptable practice of basing his new species on animals characterized in another published work, in this case the putative journal of Charles Le Raye, a French Canadian fur trader who was said to have traversed the upper Missouri River region before the Lewis and Clark Expedition and whose journal described some of the wildlife in detail. Unlike the mule deer, whose existence has been established by generations of biologists, wildlife management professionals, and sportsmen, Le Raye and his journal have since been proven to be fraudulent. Because Rafinesque's names were published in accordance with the taxonomic conventions of his time, they remain available, but, based on the questionable source of his descriptions, the identities and type localities of the species must be viewed as unreliable. Fortunately, much of the Le Raye journal was derived from other, verifiable contemporary sources. In particular, the descriptions of the two deer were based on the published journal of Patrick Gass, a member of the Lewis and Clark Expedition. Using the Gass journal as the original source of Rafinesque's descriptions, the type localities for the two deer can be reliably placed in Lyman County, South Dakota.

Objective To evaluate the clinical, methodological, and reporting aspects of systematic reviews and meta-analyses on the treatment of asthma and to compare those published by the Cochrane Collaboration with those published in paper based journals. Design Analysis of studies identified from Medline, CINAHL, HealthSTAR, EMBASE, Cochrane Library, personal collections, and reference lists. Studies Articles describing a systematic review or a meta-analysis of the treatment of asthma that were published as a full report, in any language or format, in a peer reviewed journal or the Cochrane Library. Main outcome measures General characteristics of studies reviewed and methodological characteristics (sources of articles; language restrictions; format, design, and publication status of studies included; type of data synthesis; and methodological quality). Results 50 systematic reviews and meta-analyses were included. More than half were published in the past two years. Twelve reviews were published in the Cochrane Library and 38 were published in 22 peer reviewed journals. Forced expiratory volume in one second was the most frequently used outcome, but few reviews evaluated the effect of treatment on costs or patient preferences. Forty reviews were judged to have serious or extensive flaws. All six reviews associated with industry were in this group. Seven of the 10 most rigorous reviews were published in the Cochrane Library. Conclusions Most reviews published in peer reviewed journals or funded by industry have serious methodological flaws that limit their value to guide decisions. Cochrane reviews are more rigorous and better reported than those published in peer reviewed journals. PMID:10688558
The birth and growth of a scientific journal.
Kent, Raymond D
2011-11-01
Clinical Linguistics & Phonetics (CLP) and its namesake field have accomplished a great deal in the last quarter of a century. The success of the journal parallels the growth and vitality of the field it represents. The markers of journal achievement are several, including increased number of journal pages published annually; greater diversity of topics related to the core mission of the journal; expanding cross-language coverage; and healthy interactions among editors, reviewers and contributors; and - for better or worse - journal impact factors. A journal is in a competitive dynamic with other journals that share its general domain of scholarship, which is a major reason why an apparent imbalance may emerge in the topic content of any particular journal. The content of a journal is determined by the nature and number of submitted manuscripts. As far as linguistic content goes, CLP's centre of gravity appears to have been mostly in phonology and phonetics, but certainly not to the exclusion of syntax, semantics and pragmatics. The clinical scope is broad, both in terms of concepts and types of disorder. CLP has secured its place among journals in the field, and it is an outlet of choice for many researchers throughout the world.
The role of the non-collagenous matrix in tendon function.
Thorpe, Chavaunne T; Birch, Helen L; Clegg, Peter D; Screen, Hazel R C
2013-08-01
Tendon consists of highly ordered type I collagen molecules that are grouped together to form subunits of increasing diameter. At each hierarchical level, the type I collagen is interspersed with a predominantly non-collagenous matrix (NCM) (Connect. Tissue Res., 6, 1978, 11). Whilst many studies have investigated the structure, organization and function of the collagenous matrix within tendon, relatively few have studied the non-collagenous components. However, there is a growing body of research suggesting the NCM plays an important role within tendon; adaptations to this matrix may confer the specific properties required by tendons with different functions. Furthermore, age-related alterations to non-collagenous proteins have been identified, which may affect tendon resistance to injury. This review focuses on the NCM within the tensional region of developing and mature tendon, discussing the current knowledge and identifying areas that require further study to fully understand structure-function relationships within tendon. This information will aid in the development of appropriate techniques for tendon injury prevention and treatment. © 2013 The Authors.

Disclosures of conflicts of interest in psychiatric review articles.
Kopelman, Andrew M; Gorelick, David A; Appelbaum, Paul S
2013-02-01
To characterize disclosures of conflicts of interest in review articles in psychiatry, we identified 285 reviews from 10 high-impact journals in psychiatry and 2 in general medicine. Disclosures were reliably coded as biotechnology/pharmaceutical/other material interests, nonprofit/government, communication companies, or other. The authors in both types of journals frequently reported industry ties. However, the reviews in the psychiatric journals were significantly less likely to include industry-related disclosures (32% of the reviews; 18% of the authors) compared with the general medical journals (64% of the articles; 40% of the authors). The most common types of industry-related disclosures were for consulting, research support, and speaking fees. Disclosures seemed to be of limited utility in helping readers assess possible biases because the nature and the extent of the relationships being disclosed were often unclear. Efforts to screen out authors with significant financial relationships pertaining to the topic under review may be more effective than are disclosures in protecting the integrity of the medical literature.

Should medical journals publish editorials and educational articles written by authors who have financial conflicts of interest with pharmaceutical and biotechnology industries on whose products (or their competitors) they discuss? In the last 18 months, a controversy was sparked between The New England Journal of Medicine and BMJ, who took 2 opposite positions: the former stated that the negative bias against authors with conflicts of interest with industry is excessive and therefore accept articles from any expert, ensuring that they have the minimum possible bias. BMJ, in contrast, prohibits the publication of these types of article by authors who have financial conflicts of interest with industry. This article discusses the approaches of the 2 journals (and those of others) and reflects on this type of conflict in the medical profession.

To evaluate the impact in the health care literature of research articles that provided evidence of the value of library services (including MEDLINE) as an element of quality health care. DATA SOURCES/SELECTION: Four research articles on the relationship between use of library services and quality health care were selected as "primary articles" from a MEDLINE search using appropriate Medical Subject Heading. Primary articles met the following criteria: written in English, reported research, related to clinical care, and published before 1995. The technique of citation analysis was used to measure the impact of the primary articles on the subsequent literature. The number, authorship, type, and publication venue of articles citing the primary articles were determined using ISI Web of Science, MEDLINE, other electronic resources, and the citing articles themselves. For the 146 English-language citing articles, the article type (i.e., advocacy, instructional, research) was noted; and, for those that reported research, the use to which the author put the cited material was determined. The primary articles were cited more often than the average articles published that year in the same journals. At the time of the study each article had been cited almost every year since publication. Of the 146 citing articles written in English, 43% were written by librarians, 38% by physicians, 12% by librarians with physicians. The majority were published in medical journals, followed in order of decreasing frequency by the Bulletin of the Medical Library Association, information science journals, and health administration journals. The results of this study demonstrate that published research on the value of medical library services has an impact on the literature. These articles are read and cited and continue to be of value.

The aim of this study was to evaluate the evolution of bibliometric indicators for authorship and citation of ARCHIVOS DE BRONCONEUMOLOGIA over the past 20 years. At least 16 articles reporting new research or case reports were analyzed for every other year from 1976 to 1996. The following data were collected for each article: type of document, number of authors and their place of work and specialty, time interval between acceptance and publication, and references (including number, types, language, journal name and year of publication). The number of authors per article (collaboration index) averaged around five and has not varied significantly over the 20 years studied. Pulmonologists predominated among the authors, accounting for about 60% of the total, and most contributions came from a few provinces, mainly Barcelona and Madrid. The interval between reception and publication has gradually increased over the 20 years under review, coming to stand around 9.9 +/- 1.6 months in 1996. Most references (over 80%) cite journals and the proportion of references to books has decreased in recent years (from 12.3% in 1976 to 3.5% in 1996). The journal's index of isolation has increased (from 6.2 to 12.1%), as has the index of self-citation (from 0.4 to 6.2%). Although most cited works are in English (over 80%), the proportion of Spanish-language references increased (from 6.2 to 12.1%). In conclusion, maintenance of the number of collaborating authors, the predominance of journals and English-language sources among references are the main traits that characterize the bibliometric indicators for authorship and citation in ARCHIVOS DE BRONCONEUMOLOGIA.

Introduction: Breast cancer is one of the highest reasons of deaths for people in the world. The objective of current study is to analyze and visualize the trend of global scientific activities in the field of breast cancer during a period of 10 years through 2006-2015. Methods: The current study was performed by utilizing the scientometrics analysis and mapping the co-authorship and co-organization networks. The Web of Science Core Collection (WoS-CC)database was used to extract all papers indexed as a topic of breast cancer through 2006 to 2015. Research productivity was measured through analysis several parameters, including: the number and time course of publications, the journal and language of publications, the frequency and type of publications, as well as top 20 active sub-categories together with country contribution. The extracted data were transferred into the Excel charts and plotted as diagrams. The Science of Science (Sci2) and CiteSpace softwares were used as tools for mapping the co-authorship and co-organization networks of the published papers. Results: Analysis of data indicated that the number of publications in the field of breast cancer has linearly increased and correlated with the time-course of the study. The number of publication indexed in WoS-CC in 2015 was two times greater than that of 2006, which reached from 15 229 documents in 2006 to 30 667 documents in 2015. English Language accounted for 98% of total publications as the most dominant language. The vast majority of publications' type was in the form of original journal articles (64.7%). Based on Bradford scatterings law, the journal of "Cancer Research" was the most productive journal among the core journals, while the USA, China, and England were the most prolific countries in the field. The co-organization network indicated the dominant role of Harvard University in the field. Conclusion: The integrity of network indicated that scientists in the field of breast cancer working collaboratively to tackle the number one threat in women health.

Since 1963, the Orthopaedic In-Training Examination (OITE) has been administered to orthopedic residents to assess residents' knowledge and measure the quality of teaching within individual programs. The OITE currently consists of 275 questions divided among 12 domains. This study analyzed all OITE basic science questions between 2006 and 2010. The following data were recorded: number of questions, question taxonomy, category of question, type of imaging modality, and recommended journal and book references. Between 2006 and 2010, the basic science section constituted 12.2% of the OITE. The assessment of taxonomy classification showed that recall-type questions were the most common, at 81.4%. Imaging modalities typically involved questions on radiographs and constituted 6.2% of the OITE basic science section. The majority of questions were basic science questions (eg, genetics, cell replication, and bone metabolism), with an average of 26.4 questions per year. The Journal of Bone & Joint Surgery (American Volume) and the American Academy of Orthopaedic Surgeons' Orthopaedic Basic Science were the most commonly and consistently cited journal and review book, respectively. This study provides the first review of the question content and recommended references of the OITE basic science section. This information will provide orthopedic trainees, orthopedic residency programs, and the American Academy of Orthopaedic Surgeons Evaluation Committee valuable information related to improving residents' knowledge and performance and optimizing basic science educational curricula.

To identify and characterize the most frequently cited articles that have been published on aortic dissection. A list of the 100 most frequently cited publications (T100) about aortic dissection was generated by performing a searching of the Science Citation Index--Expanded using "aortic dissection" as the search term. Basic information about the articles was recorded, including number of citations, journal title, journal impact factor, time since publication, first author's country, topic/subspecialty of the research, and publication type. We finally included 180 articles on aortic dissection, from which we identified the 100 most frequently cited articles (T100). The most frequently cited article received 1079 citations, while the least frequently cited article received 68 (mean140.5 citations per article). The T100 originated from 19 countries, with more than half of them originating from the USA (n = 97). The T100 articles were published from 1955 to 2013, with 79% published during the period 1990-2009. In addition, there were 40 different journals with Circulation having the most citations (n = 38). Regarding the article type, there were 21 basic and 140 clinical research articles, one meta-analysis, and 18 review articles. Reviews had the highest mean number of citations (mean 235.5 citations per article). Our study provides a historical perspective on the progress of dissection research, and helps to identify the quality of the work, the discoveries made, and the trends steering the studies.
Disappearing act: decay of uniform resource locators in health care management journals
Wagner, Cassie; Gebremichael, Meseret D.; Soltys, Michael J.
2009-01-01
Objectives: This study examines the problem of decay of uniform resource locators (URLs) in health care management journals and seeks to determine whether continued availability at a given URL relates to the date of publication, the type of resource, or the top-level URL domain. Methods: The authors determined the availability of web-based resources cited in articles published in five source journals from 2002 to 2004. The data were analyzed using correlation, chi-square, and descriptive statistics. Attempts were made to locate the unavailable resources. Results: After checking twice, 49.3% of the original 2,011 cited resources could not be located at the cited URL. The older the article, the more likely that URLs in the reference list of that article were inactive (r = −0.62, P<0.001, n = 1,968). There was no difference in availability across resource types (χ2 = 5.28, df = 2, P = 0.07, n = 1,786). Whether an URL was active varied by top-level domain (χ2 = 14.92, df = 4, P = 0.00, n = 1,786). Conclusions: URL decay is a serious problem in health care management journals. In addition to using website archiving tools like WebCite, publishers should require authors to both keep copies of Internet-based information they used and deposit copies of data with the publishers.

The Medical Article Records System or MARS has been developed at the U.S. National Library of Medicine (NLM) for automated data entry of bibliographical information from medical journals into MEDLINE, the premier bibliographic citation database at NLM. Currently, a rule-based algorithm (called ZoneCzar) is used for labeling important bibliographical fields (title, author, affiliation, and abstract) on medical journal article page images. While rules have been created for medical journals with regular layout types, new rules have to be manually created for any input journals with arbitrary or new layout types. Therefore, it is of interest to label any journal articles independent of their layout styles. In this paper, we first describe a system (called ZoneMatch) for automated generation of crucial geometric and non-geometric features of important bibliographical fields based on string-matching and clustering techniques. The rule based algorithm is then modified to use these features to perform style-independent labeling. We then describe a performance evaluation method for quantitatively evaluating our algorithm and characterizing its error distributions. Experimental results show that the labeling performance of the rule-based algorithm is significantly improved when the generated features are used.
[An analysis of Chilean biomedical publications in PubMed in the years 2008-2009].

2015-08-01
During the years 2008 and 2009, 1,191 biomedical articles authored by Chilean investigators working in Chile were indexed in PubMed. To evaluate the potential visibility of those articles, according to scientometric indexes of the journals where they were published. Those journals where the articles had been published were identified and each journals Impact Factor (JIF), 5-year JIF, SCImago Journal Rank (SJR), SCImago Quartiles (Q) for 2010 and the Source Normalized Impact per Paper (SNIP) for 2008-2009 were identified. Three hundred and twelve articles (26,2%) were dedicated to experimental studies in animals, tissues or cells and they were classified as Biomedicine, while 879 (73,8%) were classified as Clinical Medicine; in both areas the main type of articles were original reports (90% and 73.6%, respectively). Revista Médica de Chile and Revista Chilena de Infectología concentrated the greater number of publications. Articles classified in Biomedicine were published more frequently in English and in journals with higher scientometric indexes than those classified in Clinical Medicine. Biomedical articles dealing with clinical topics, particularly case reports, were published mostly in national journals or in foreign journals with low scientometric indexes. It can be partly attributable to the authors interest in reaching local readers. The evaluation of research productivity should combine several scientometric indexes, selected according to the field of research, the institution's and investigators interests, with a qualitative and multifactorial assessment.

To explore the role of traditional Chinese medicine (TCM) syndrome scores in effectiveness evaluation of clinical studies. Randomized controlled trials (RCTs) of TCM published in five journals in 2013 were retrieved, including Journal of Traditional Chinese Medicine (JTCM), Chinese Journal of Integrated Traditional and Western Medicine (CJITWM), Chinese Journal of Integrative Medicine (CJIM), Evidence-Based Complementary and Alternative Medicine (ECAM), and American Journal of Chinese Medicine (AJCM). The details of TCM syndrome scores and other relevant factors reported in articles were extracted and analyzed. Descriptive statistics and Chi-square test were used to describe general features of inclusive studies, ratios of reports on CM syndrome scores in each journal, formulated evidence, adopted evaluation rules, important degrees. The difference in the application rate of CM syndrome scores were compared in various diseases, diseases with or without CM syndrome typing, places where clinical studies were implemented, and different journals. A total of 240 RCTs were included, involving 178 published in Chinese version and 62 in English version. CM syndrome scores were used for effectiveness evaluation in 27.1% (65/240) of RCTs, of which, the highest application percentage was 35.3% (18/51) in RCTs published in CJITWM, and the lowest was 0 (0/7) in RCTs published in AJCM. There were 17 methods for grading TCM syndrome scores, of which Guideline for Clinical Research of New Chinese Herbal Medicine was most commonly used. Detailed grading standards for CM syndrome scores were reported in 46 RCTs, and CM syndrome scores were taken as primary or secondary outcomes in 6 RCTs. When describing the percentages of RCTs adopting TCM syndrome score by diseases classification, the lowest was 9.5% (2/21) in mental and behavioral disorders, and the highest was 39.1% (9/23) in endocrine, nutritional, and metabolic diseases. RCTs with TCM syndrome differentiation had a higher percentage of adopting TCM syndrome score than those without TCM syndrome differentiation (P < 0.01). Statistical differences were also found among RCTs published in Chinese core journals (32.0%), domestic science citation index (SCI) journals (28.6%), and overseas SCI journals (4.9%) (χ2 = 12.4593, P < 0.01). For RCTs conducted by Chinese scholars, the percentage of using TCM syndrome score was 32.0% in three journals from China, while 7.1% in two foreign language journals, showing significant difference (χ2 =7.3615, P < 0.01); none of RCTs conducted by foreign scholars used TCM syndrome scores for effectiveness assessment. There was a lack of agreeable and universal standards for TCM syndrome scores using in effectiveness evaluation. Therefore, it was not commonly used in domestic CM clinical studies. It was not so favorably agreed in overseas academic circles.

The relationship between industry funding and study results has been explored widely in medicine but not in dentistry. The authors aimed to assess the relationship between conflicts of interest (COIs) and study results. The authors assessed all randomized clinical trials (RCTs) published between July 2010 and June 2012 in the 10 dental journals with the highest impact factors in dentistry. The authors used three definitions of COI and explored their associations with positive study results. Depending on the definition of COI, the odds ratio for reporting positive results varied between 2.40 (95 percent confidence interval [CI], 1.16-5.13) and 9.19 (95 percent CI, 1.71-170.64). The authors found no association between positive study results and journal of publication or area of practice. RCTs in which authors have some type of COI are more likely to have results that support the intervention being assessed. When reviewing the results of RCTs, clinicians need to be aware of the association between reporting positive study results and the type of COI disclosure and be even more careful when critically appraising and applying their results.
Authorship Inflation in Medical Publications.
Tilak, Gaurie; Prasad, Vinay; Jena, Anupam B
2015-01-01
The number of authors per manuscript in peer-reviewed medical journals has increased substantially in the last several decades. Several reasons have been offered to explain this authorship growth, including increased researcher collaboration, honorary authorship driven by increased pressures for funding and promotion, the belief that including senior authors will facilitate publication, and the growing complexity of medical research. It is unknown, however, whether authorship has grown over time due to growing complexity of published academic articles, in which case growth could be warranted, or whether it has grown due to pressures of funding and academic promotion, which have created "authorship inflation." To answer this question, we analyzed data on authorship count, study type, and size of study population for the first 50 original articles published in each decade during 1960-2010 in 3 major medical journals. Within each type of study we considered (eg, randomized trials, observational studies, etc), average authorship rose more than 3-fold during this period. Similar growth persisted after adjustment for changes in study population sizes over time. Our findings suggest that increasing research complexity is an inadequate explanation for authorship growth. Instead, growth in authorship appears inflationary. © The Author(s) 2015.

The purpose of this study was to identify the clinical pediatric orthopaedic articles with at least 100 citations published in all orthopaedic journals and to examine their characteristics. All journals dedicated to orthopaedics and its subspecialties were selected from the Journal Citation Report 2001 under the subject category "orthopedics." Articles cited 100 times or more were identified using the database of the Science Citation Index Expanded (SCI-EXPANDED, 1900 to present). The articles were ranked in a comprehensive list. Two authors independently reviewed the full text of each article and applied the inclusion and exclusion criteria to the list of articles. The 2 lists were then compared. All disagreements were resolved by consensus with input from the senior author. The final list of pediatric orthopaedic articles was then compiled. There were a total of 49 journals under the search category "orthopedics." Five journals were excluded as they were non-English journals. The remaining 44 journals were screened for articles with at least 100 citations. A total of 135 clinical pediatric orthopaedic articles cited at least 100 times were included. The most cited article was cited 692 times. The mean number of citations per article was 159 (95% confidence interval, 145-173). All the articles were published between 1949 and 2001, with 1980 and 1989 producing the most citation classics (34). The majority (90) originated from the United States, followed by the United Kingdom (12) and Canada (11). Scoliosis/kyphosis was the most common topic with 26 papers. The second most common subject was hip disorders (24). Therapeutic studies were the most common study type (71). Ninety-seven papers were assigned a 4 for level of evidence. The list of citation classics in pediatric orthopaedic articles is useful for several reasons. It identifies important contributions to the field of pediatric orthopaedics and their originators; it facilitates the understanding and discourse of modern pediatric orthopaedic history and reveals trends in pediatric orthopaedics.

To review trends in articles published during the first 20 years of The Journal of Chiropractic Education (JCE), which is the primary periodical that publishes chiropractic educational research. This study focused on article type, country of origin, contributions by institutions, use of references, and use of structured abstracts. All volumes of the JCE were retrieved (1987-2006). Only full articles were included in this study; abstracts from proceedings and ephemera were excluded from this analysis. Articles that presented no data (eg, commentary, narrative descriptions) were classified as nondata articles. Articles that reported data (eg, experimental studies, survey research, etc) were classified as data articles. Each article was reviewed by hand for the type of study (data vs nondata), geographic region of origin, college of origin, use of references, and the presence of a structured or unstructured abstract. After applying the inclusion and exclusion criteria, 153 papers were assessed. Published articles came from 5 countries and represented 23 chiropractic colleges. A majority (80.2%) of papers were from the United States. Of all articles, 101 articles (66%) were nondata in nature. Consistent use of references and structured abstracts increased over time. During its first 20 years, the JCE has published more nondata than data studies and the number of data papers published per year has remained constant. The journal has reached a consistent level of quality in its publication of manuscripts containing structured abstracts and references, and articles have been authored primarily by US authors. It is recommended that more efforts and resources are dedicated to data-driven studies and that greater geographic diversity is obtained to better represent the worldwide distribution of the chiropractic profession's educational institutions.
Qualitative Environmental Health Research: An Analysis of the Literature, 1991–2008
Scammell, Madeleine Kangsen
2010-01-01
Background Recent articles have advocated for the use of qualitative methods in environmental health research. Qualitative research uses nonnumeric data to understand people’s opinions, motives, understanding, and beliefs about events or phenomena. Objective In this analysis of the literature, I report the use of qualitative methods and data in the study of the relationship between environmental exposures and human health. Data sources A primary search on ISI Web of Knowledge/Web of Science for peer-reviewed journal articles dated from 1991 through 2008 included the following three terms: qualitative, environ*, and health. Inclusion and exclusion criteria are described. Data extraction Searches resulted in 3,155 records. Data were extracted and findings of articles analyzed to determine where and by whom qualitative environmental health research is conducted and published, the types of methods and analyses used in qualitative studies of environmental health, and the types of information qualitative data contribute to environmental health. Data synthesis Ninety-one articles met inclusion criteria. These articles were published in 58 different journals, with a maximum of eight for a single journal. The results highlight a diversity of disciplines and techniques among researchers who used qualitative methods to study environmental health, with most studies relying on one-on-one interviews. Details of the analyses were absent from a large number of studies. Nearly all of the studies identified increased scientific understanding of lay perceptions of environmental health exposures. Discussion and conclusions Qualitative data are published in traditionally quantitative environmental health studies to a limited extent. However, this analysis demonstrates the potential of qualitative data to improve understanding of complex exposure pathways, including the influence of social factors on environmental health, and health outcomes.

Observational studies dominate the surgical literature. Statistical adjustment is an important strategy to account for confounders in observational studies. Research has shown that published articles are often poor in statistical quality, which may jeopardize their conclusions. The Statistical Analyses and Methods in the Published Literature (SAMPL) guidelines have been published to help establish standards for statistical reporting.This study will seek to determine whether the quality of statistical adjustment and the reporting of these methods are adequate in surgical observational studies. We hypothesize that incomplete reporting will be found in all surgical observational studies, and that the quality and reporting of these methods will be of lower quality in surgical journals when compared with medical journals. Finally, this work will seek to identify predictors of high-quality reporting. This work will examine the top five general surgical and medical journals, based on a 5-year impact factor (2007-2012). All observational studies investigating an intervention related to an essential component area of general surgery (defined by the American Board of Surgery), with an exposure, outcome, and comparator, will be included in this systematic review. Essential elements related to statistical reporting and quality were extracted from the SAMPL guidelines and include domains such as intent of analysis, primary analysis, multiple comparisons, numbers and descriptive statistics, association and correlation analyses, linear regression, logistic regression, Cox proportional hazard analysis, analysis of variance, survival analysis, propensity analysis, and independent and correlated analyses. Each article will be scored as a proportion based on fulfilling criteria in relevant analyses used in the study. A logistic regression model will be built to identify variables associated with high-quality reporting. A comparison will be made between the scores of surgical observational studies published in medical versus surgical journals. Secondary outcomes will pertain to individual domains of analysis. Sensitivity analyses will be conducted. This study will explore the reporting and quality of statistical analyses in surgical observational studies published in the most referenced surgical and medical journals in 2013 and examine whether variables (including the type of journal) can predict high-quality reporting.

An observational study was conducted to describe the presence of plagiarism in medical thesis in 2008 performed at a public university in Peru. Search for plagiarism in 33 thesis introductions using a Google search algorithm, characterizes of the study type and we search in electronic form if the thesis mentor have published articles in scientific journals. We found evidence of plagiarism in 27/33 introductions, 37.3% (171/479) of all the paragraphs analyzed had some degree of plagiarism, literal plagiarism was the most frequent (20/27) and journals were the most common sources of plagiarism (19/27). The characteristics of the studies were observational (32/33), cross-sectional (30/33), descriptive (25/33) and retrospective (19/33). None of the authors had published in a scientific journal, and only nine of his tutors of them had at least one publication. No association was found between the characteristics of the thesis and the presence of plagiarism. In conclusion, we found a high frequency of plagiarism in theses analyzed. Is responsibility of medical schools take the necessary actions to detect and avoid plagiarism among their students.

A central tenet in support of research reproducibility is the ability to uniquely identify research resources, i.e., reagents, tools, and materials that are used to perform experiments. However, current reporting practices for research resources are insufficient to identify the exact resources that are reported or to answer basic questions such as “How did other studies use resource X?” To address this issue, the Resource Identification Initiative was launched as a pilot project to improve the reporting standards for research resources in the Methods sections of articles and thereby improve identifiability and scientific reproducibility. The pilot engaged over 25 biomedical journal editors from most major publishers, as well as scientists and funding officials. Authors were asked to include Research Resource Identifiers (RRIDs) in their articles prior to publication for three resource types: antibodies, model organisms, and tools (i.e., software and databases). RRIDs are assigned by an authoritative database, for example, a model organism database for each type of resource. To make it easier for authors to obtain RRIDs, resources were aggregated from the appropriate databases and their RRIDs made available in a central Web portal (http://scicrunch.org/resources). RRIDs meet three key criteria: they are machine‐readable, free to generate and access, and are consistent across publishers and journals. The pilot was launched in February of 2014 and over 300 articles have appeared that report RRIDs. The number of journals participating has expanded from the original 25 to more than 40, with RRIDs appearing in 62 different journals to date. Here we present an overview of the pilot project and its outcomes to date. We show that authors are able to identify resources and are supportive of the goals of the project. Identifiability of the resources post‐pilot showed a dramatic improvement for all three resource types, suggesting that the project has had a significant impact on identifiability of research resources.

To evaluate the online visibility of the most popular orthodontic articles in Web platforms in relation to publication details and citations. Altmetric Explorer (Altmetric LLP, London, UK) was searched for articles published in 11 orthodontic journals without time limits in publication and citation on social media. The 200 articles with the highest Altmetric Attention Score (AAS) were collected and screened for data related to publication (date, journal, access), authorship (number of authors, affiliation and origin of the corresponding author), and research (type, subject, funding). Citation counts were harvested from Scopus. The top 200 articles presented a median AAS of 8.0 (range: 5.0-196.0), and were mostly bookmarked in Mendeley (median: 16.6 references; range: 0-199.0). American Journal of Orthodontics & Dentofacial Orthopedics, European Journal of Orthodontics and The Angle Orthodontist contributed 86 per cent of the total number of research outputs. Studies investigating socio-demographics had significantly higher AAS compared to diagnostic studies (median AAS: 19.0; range: 7.0-34.0; versus median AAS: 6.0; range: 5.0-10.0. No other study parameter was found to be statistically significant. AAS did not correlate to the number of citations as reported in Scopus. The early stage of altmetrics and their complementary role in assessing together with the citation-based metrics the research impact need to be acknowledged in the interpretation of the results. Visibility of orthodontic articles on the Web is not significantly correlated with citations. Studies on socio-demographics had significantly higher number of online mentions. More constructive online presence of orthodontic journals is needed to reinforce dissemination of research data among scholars and non-scholars.

The advancement of knowledge is based on the results of previously conducted research studies, which are reflected in the reference sources listed in a scientific article. This study is aimed at studying the scientific information used in the Revista Española de Salud Pública based on the references cited in the original articles published during the 1991-2000 period. The data regarding the year and where published, document type, language and country in which published was taken from the reference sources listed in the 290 original articles published, the obsolescence, Price and isolation indexes being calculated, and the Bradford core distribution being established according to the source journals. The self-citing rate was also calculated. A total of 7465 references were cited in the Reference section of the 290 original articles. An average of 25.7 references were cited per article. The Price index was 40.7. The scientific articles showed an obsolescence index of 5, the books and book chapters having an index of 6. A total 50.6% of the citations were from studies published in Spanish. The isolation index of the references was 48.1. The first Bradford core is comprised of 10 journals, the first four of which are Spanish. The self-citing rate was 3.8%. The information consumption of the original articles published in the Revista Española de Salud Pública show parameters similar to those of other Spanish health sciences journals for those same years, and the parameters regarding which this Journal differs from other Spanish health sciences journals seem to be justified by those particular aspects unique to public health, which does not fall within the patterns inherent to the clinical disciplines.

To evaluate the publication rate of submitted abstracts accepted for presentation at the 2010 Canadian Ophthalmological Society (COS) Annual Meeting in peer-reviewed journals. A retrospective analysis and literature search of abstracts presented at the 2010 COS Annual Meeting. Abstracts accepted as an oral presentation or poster from the 2010 COS Annual Meeting were tabulated by type of presentation (oral vs poster), subspecialty, study design, number of authors, and principal investigator's institution. A PubMed search was conducted for each abstract by key word, first author, and last author. The year of publication, journal, and impact factor were recorded for identified publications. Publication rate was calculated by type of presentation, subspecialty, study design, number of authors, and institution. A total of 175 abstracts were presented at the 2010 COS Annual Meeting. There were 105 oral (60%) and 70 poster (40%) presentations. The overall publication rate was 45.7%; 49.5% for oral presentations and 40.0% for posters. Cornea (57.6%) and public health (54.5%) had the highest publication rates of all subspecialties. Randomized control trials (71.4%) and cohort studies (70.0%) had higher publication rates than other study designs. Overall, 28.8% of abstracts were published in the Canadian Journal of Ophthalmology. The average impact factor of all publications was 2.73. Of abstracts presented at the 2010 COS Annual Meeting, 45.7% were published within 5 years after the conference. This publication rate is within the upper end of previously reported meeting publication rates for medical societies. Copyright © 2017 Canadian Ophthalmological Society. Published by Elsevier Inc.

Analysis of a novel class of predictive microbial growth models and application to coculture growth.
Poschet, F; Vereecken, K M; Geeraerd, A H; Nicolaï, B M; Van Impe, J F
2005-04-15
In this paper, a novel class of microbial growth models is analysed. In contrast with the currently used logistic type models (e.g., the model of Baranyi and Roberts [Baranyi, J., Roberts, T.A., 1994. A dynamic approach to predicting bacterial growth in food. International Journal of Food Microbiology 23, 277-294]), the novel model class, presented in Van Impe et al. (Van Impe, J.F., Poschet, F., Geeraerd, A.H., Vereecken, K.M., 2004. Towards a novel class of predictive microbial growth models. International Journal of Food Microbiology, this issue), explicitly incorporates nutrient exhaustion and/or metabolic waste product effects inducing stationary phase behaviour. As such, these novel model types can be extended in a natural way towards microbial interactions in cocultures and microbial growth in structured foods. Two illustrative case studies of the novel model types are thoroughly analysed and compared to the widely used model of Baranyi and Roberts. In a first case study, the stationary phase is assumed to be solely resulting from toxic product inhibition and is described as a function of the pH-evolution. In the second case study, substrate exhaustion is the sole cause of the stationary phase. Finally, a more complex case study of a so-called P-model is presented, dealing with a coculture inhibition of Listeria innocua mediated by lactic acid production of Lactococcus lactis.
Mapping the literature of pediatric nursing
Taylor, Mary K.
2006-01-01
Background: Pediatric nurses work in an interdisciplinary field and face ever-increasing demands on their time and knowledge. Selection tools for librarians serving this group are available, but only one bibliometric analysis has examined citations to aid collection development. Method: The “Mapping the Literature of Nursing Project” protocol was used. Three source journals were selected, and a citation analysis of articles from 1998 to 2000 was conducted. Results: The frequency of journal citation was tabulated, and a list of the most frequently cited journals was created. Just over 1% of the cited journals produced 33% of the citations. PubMed/MEDLINE, Science Citation Index, and Social Sciences Citation Index provided the most complete indexing coverage of all types of the journals, while CINAHL providing the most complete coverage of nursing journals. Books were the second-most frequently cited format. Conclusions: Citation analysis of journal articles from pediatric nursing journals may be helpful in selecting journals for libraries serving pediatric nurses and those who conduct pediatric nursing research. Librarians should consider adding indexes to their collection in addition to PubMed/MEDLINE to access the broad range of journals useful to this specialty. PMID:16710459

Analysis, design, and testing of two types of pivoted pad journal bearings and a spiral-grooved thrust bearing suitable for direct installation into the NASA 2 to 15 KW Brayton Cycle Rotating Unit (BRU) have been accomplished. Both types of tilting pad bearing assemblies are of the preloaded type, consisting of three pads with one pad flexibly mounted. One type utilizes a non-conforming pivot, while the other replaces the conventional spherical pivot with a cruciform flexible member. The thrust bearing is flexure mounted to accommodate static machine mislinement. Test results indicate that both types of journal bearings should satisfy the requirements imposed by the BRU. Hydrostatic tests of the spiral-grooved thrust bearing showed it to be free of pneumatic hammer with as many as 24 orifices over the BRU pressure and load range.

The ethical aspects of the Brazilian publications about human Chagas disease (CD) developed between 1996 and 2010 and the policy adopted by Brazilian medical journals were analyzed. Articles were selected on the SciELO Brazil data basis, and the evaluation of ethical aspects was based on the normative contents about ethics in research involving human experimentation according to the Brazilian resolution of the National Health Council no. 196/1996. The editorial policies of the section "Instructions to authors" were analyzed. In the period of 1996-2012, 58.9% of articles involving human Chagas disease did not refer to the fulfillment of the ethical aspects concerning research with human beings. In 80% of the journals, the requirements and confirmation of the information about ethical aspects in the studies of human CD were not observed. Although a failure in this type of service is still observed, awareness has been raised in federal agencies, educational institutions/research and publishing groups to standardize the procedures and ethical requirements for the Brazilian journals, reinforcing the fulfillment of the ethical parameters, according to the resolution of NHC no. 196/1996.
[Analysis on acupuncture literature in Science Citation Index (SCI) periodicals in 2007].

To grasp the international developing tendency of acupuncture research and provide some references for promoting acupuncture and moxibustion internationalization process, the articles about acupuncture in Science Citation Index (SCI) periodicals in 2007 were retrieved by adopting the retrieval tactics on line in combination with database searching. Results indicate that 257 articles about acupuncture had been retrived from the SCI Web databases. These articles were published in 125 journals respectively, most of which were Euramerican journals. Among these journals, the impact factor of the Journal of the American Medical Association (JAMA), 25. 547, is the highest one. It is shown that the impact factors of the SCI periodicals, in which acupuncture articles embodied are increased, the quality of these articles are improved obviously and the types of the articles are various in 2007, but there is obvious difference in the results of these studies due to the difference of experimental methods, the subjects of these experiments and acupuncture manipulations. Therefore, standardization of many problems arising from the researches on acupuncture is extremely imminent.

To identify the 100 most-cited articles pertaining to human cleft lip and palate research published in dentistry, oral surgery, and medicine journals and to identify their principal bibliometric characteristics. Web-based bibliometric analysis. The Web of Science was searched to identify the 100 most-cited clinical articles related to cleft lip and/or palate. Information was extracted with regard to total number of citations, number of authors, affiliations, year, and journal of publication, Medical Subject Headings, type of study, specific area of study. Trends in citations were assessed. The 100 most-cited articles identified received between 437 and 58 citations. The oldest was published in 1954 and the most recent in 2008. The number of authors ranged from 1 to 12, with an average of three authors per article. Most of the first authors were affiliated with institutions in the United States, with the most prolific institution being the University of Iowa. More than 70% of the studies appeared in The Cleft Palate-Craniofacial Journal. There was a significant negative correlation between average citations per year and time since publication (P < .001); whereas, a significant positive correlation was observed between average citations per year and number of total citations (P < .001). The 100 most-cited articles in human cleft lip and palate research published in dentistry, oral surgery, and medicine journals are listed and characterized. This can be used as a potential knowledge base for specialists in training or to produce relevant knowledge defining the direction of future research.

To identify and describe randomized controlled trials (RCTs) and systematic reviews (SRs) on patient safety published from 1973 onward. We handsearched a total of 12 medical journals published in English with contents related to patient safety to identify RCTs and SRs published between 1973 and the end of 2010. The results obtained from this search were complemented with an additional search in MEDLINE. The documents were classified by area of specialty or service in which the intervention was applied, level of preventive action, and type of patient safety incident, the latter in accordance with the International Classification for Patient Safety proposed by the World Health Organization (WHO). The main features of the identified studies are also described. A total of 787 issues of 12 journals published between 1973 and 2010 were handsearched. This procedure yielded 10,162 references, of which, 131 corresponded to RCTs and 127 to SRs. A parallel MEDLINE search identified only about two-thirds of these articles. Of all the studies identified, 83 RCTs and 64 SRs addressed interventions related to patient safety. The types of incident related to patient safety that were included most often in RCTs involved the clinical process, and for SRs, those related to resources/organizational management. On average, only 3.5 RCTs and 3.4 SRs were published per year, many of which had significant deficiencies in the reported information, such as, for instance, a lack of details on the methodology used. The number of RCTs and SRs on patient safety published in specialized journals is scarce. No studies on interventions to improve the safety of the handling of blood and derivatives, infections related to health care, nutrition, or infrastructure were identified as a result of our search. Handsearching plays a key role in the identification of all the clinical trials that could be included in SRs on patient safety interventions. Knowing the content of RCTs and SRs published on patient safety can better target future research.

Randomized controlled trials (RCTs) that use the modified intention-to-treat (mITT) approach are increasingly being published. Such trials have a preponderance of post-randomization exclusions, industry sponsorship, and favourable findings, and little is known whether in terms of these items mITT trials are different with respect to trials that report a standard intention-to-treat. To determine differences in the methodological quality, sponsorship, authors' conflicts of interest, and findings among trials with different "types" of intention-to-treat, we undertook a cross-sectional study of RCTs published in 2006 in three general medical journals (the Journal of the American Medical Association, the New England Journal of Medicine and the Lancet) and three specialty journals (Antimicrobial Agents and Chemotherapy, the American Heart Journal and the Journal of Clinical Oncology). Trials were categorized based on the "type" of intention-to-treat reporting as follows: ITT, trials reporting the use of standard ITT approach; mITT, trials reporting the use of a "modified intention-to-treat" approach; and "no ITT", trials not reporting the use of any intention-to-treat approach. Two pairs of reviewers independently extracted the data in duplicate. The strength of the associations between the "type" of intention-to-treat reporting and the quality of reporting (sample size calculation, flow-chart, lost to follow-up), the methodological quality of the trials (sequence generation, allocation concealment, and blinding), the funding source, and the findings was determined. Odds ratios (OR) were calculated with 95% confidence intervals (CI). Of the 367 RCTs included, 197 were classified as ITT, 56 as mITT, and 114 as "no ITT" trials. The quality of reporting and the methodological quality of the mITT trials were similar to those of the ITT trials; however, the mITT trials were more likely to report post-randomization exclusions (adjusted OR 3.43 [95%CI, 1.70 to 6.95]; P < 0.001). We found a strong association between trials classified as mITT and for-profit agency sponsorship (adjusted OR 7.41 [95%CI, 3.14 to 17.48]; P < .001) as well as the presence of authors' conflicts of interest (adjusted OR 5.14 [95%CI, 2.12 to 12.48]; P < .001). There was no association between mITT reporting and favourable results; in general, however, trials with for-profit agency sponsorship were significantly associated with favourable results (adjusted OR 2.30; [95%CI, 1.28 to 4.16]; P = 0.006). We found that the mITT trials were significantly more likely to perform post-randomization exclusions and were strongly associated with industry funding and authors' conflicts of interest.
Physical Review: a family of journals

Sprouse, Gene
2013-03-01
The expansion of research in physics in the last 100 years has been reflected in the expansion of the Physical Review(PR). Reviews of Modern Physics was the first ``new'' journal, starting in 1929. Physical Review Letters commenced in 1958, and was the first ``letters'' type of journal for important new results in all fields. By 1970 the Physical Review itself had grown so large that it was necessary to separate it by field into manageable volumes: PRA, PRB, PRC and PRD, and subsequently PRE, which was split off from PRA. More recently, two Special Topics journals for accelerator physics and physics education were pioneers of the open access business model, and the newest member of the family, Physical Review X, continues this trend. PRX is broad scope and very selective, setting it well above many of the new open access journals with a review standard of ``not incorrect.'' Some possible future directions for the Physical Review journals will be discussed.
Excessive and disproportionate advertising in peer-reviewed journals.
Friedman, Lee S; Richter, Elihu D
2006-01-01
The International Committee of Medical Journal Editors (ICMJE) has outlined ethical guidelines concerning the advertising practices of peer-reviewed journals that briefly discuss issues of excessive and disproportionate advertising. The authors evaluated these guidelines using quantitative data, assessing the types and frequencies of advertising in 2001 print issues of NEJM and JAMA, two principal members of ICMJE. Advertising ratios (ratio of advertisements to editorial content) were near unity in NEJM and 0.30 in JAMA, compared with reported ratios of 0.15 among low-circulation specialty science journals and 0.80 among high-circulation consumer magazines. In both journals, five corporations placed more than 50% of all display advertisements. The findings suggest a dissonance between the ethical guidelines and the de facto advertising practices of arguably the two most important member journals of the ICMJE. There is a need to define and apply standards for excessive and disproportionate advertising.

We aimed to analyze scientific papers published by Turkish authors in "radiology, nuclear medicine and medical imaging" journals included in the Science Citation Index Expanded and compared the number of published scientific papers from Turkey and other countries. We retrospectively searched all papers published by Turkish authors between 1945 and 2008 by using Web of Science software. We performed the analysis by typing "Turkey" in the address section and all radiology and medical imaging journals in the source title section using the general search function of the software. We further analyzed these results by using "analyze" function of the software according to the number of publications per year, journals, institution and type of papers. We also calculated total number of citations to published scientific papers using citation report function. We analyzed the rank of Turkey among other countries in terms of the number of published papers. Overall, 4,532 papers were published between 1945 and 2008. The first paper was published in 1976. Number of publications increased dramatically from 1976 (n = 1) to 2008 (n = 383). The top 5 journals publishing papers from Turkish authors were European Journal of Nuclear Medicine and Molecular Imaging (n = 328), Clinical Nuclear Medicine (n = 296), European Journal of Radiology (n = 289), European Radiology (n = 207) and Journal of Clinical Ultrasound (n = 186). All published papers received 18,419 citations and citation to paper ratio was 4.06. The rank of Turkey among other countries in terms of published papers improved during the last 25 years. Number of papers from Turkey published in radiology and medical imaging journals has increased at the start of the new millennium. Currently, Turkey is among the top 12 countries when the number of scientific papers published in radiology journals is taken into consideration.

Abstract Objective To investigate the distribution, design characteristics, and dissemination of clinical trials by funding organisation and medical specialty. Design Cross sectional descriptive analysis. Data sources Trial protocol information from clinicaltrials.gov, metadata of journal articles in which trial results were published (PubMed), and quality metrics of associated journals from SCImago Journal and Country Rank database. Selection criteria All 45 620 clinical trials evaluating small molecule therapeutics, biological drugs, adjuvants, and vaccines, completed after January 2006 and before July 2015, including randomised controlled trials and non-randomised studies across all clinical phases. Results Industry was more likely than non-profit funders to fund large international randomised controlled trials, although methodological differences have been decreasing with time. Among 27 835 completed efficacy trials (phase II-IV), 15 084 (54.2%) had disclosed their findings publicly. Industry was more likely than non-profit trial funders to disseminate trial results (59.3% (10 444/17 627) v 45.3% (4555/10 066)), and large drug companies had higher disclosure rates than small ones (66.7% (7681/11 508) v 45.2% (2763/6119)). Trials funded by the National Institutes of Health (NIH) were disseminated more often than those of other non-profit institutions (60.0% (1451/2417) v 40.6% (3104/7649)). Results of studies funded by large drug companies and NIH were more likely to appear on clinicaltrials.gov than were those from non-profit funders, which were published mainly as journal articles. Trials reporting the use of randomisation were more likely than non-randomised studies to be published in a journal article (6895/19 711 (34.9%) v 1408/7748 (18.2%)), and journal publication rates varied across disease areas, ranging from 42% for autoimmune diseases to 20% for oncology. Conclusions Trial design and dissemination of results vary substantially depending on the type and size of funding institution as well as the disease area under study. PMID:29875212
Pharmacists' Roles in Post-September 11th Disasters: A Content Analysis of Pharmacy Literature.
Ford, Heath; von Waldner, Trina; Perri, Matthew
2014-08-01
To characterize the roles pharmacists have assumed in disasters and clarify the types of roles and disasters that may be less well-documented in the pharmacy literature. This research examines how balanced or equally proportioned role categories are in the pharmacy literature, whether pharmacy journals differ in the proportion of role categories reported, and whether journals significantly differ in the proportion of reported chemical, biological, radiological, nuclear (CBRN), and natural disasters. Data coding was performed solely by the lead author using Concordance (Harvard University, Cambridge, Massachusetts), a Web-based content analysis software, and Minitab(®) (version 15; Minitab, Inc; State College, Pennsylvania) for descriptive and inferential statistical analysis. Pharmacy journals publishing at least 2 articles about pharmacist disaster roles from September 11, 2001 to September 30, 2011 were used in the study and were available electronically. Chi-square analyses reveal significant differences in the weighted counts of roles, roles categorized by journal, and CBRN disasters categorized by journal. Data suggest that pharmacists may be prepared to respond to hurricanes and biological and chemical disasters in pharmaceutical supply and patient management roles. Future research should highlight efforts to prepare health systems for the effects of nuclear, radiological, and chemical disasters. © The Author(s) 2013.

The purpose of this study was to identify and characterize the 100 top-cited articles in pulmonary imaging. From the database of Journal Citation Reports, 274 journals whose scope included pulmonary imaging were selected. The Web of Science search tools were then used to identify the 100 top-cited articles in the subject of pulmonary imaging published in these journals. The parameters used to analyze the characteristics of the 100 top-cited articles were journal (including subject category and impact factor), publication year, number of citations and annual citations, department and institution of authors, country of origin, article type, imaging technique, and topic. The 100 top-cited articles in pulmonary imaging were published between 1953 and 2012, with 43 published between 2000 and 2009. Citations ranged from 199 to 1447, and annual citations ranged from 5.1 to 314. The majority of articles were published in radiology or imaging journals (n=64), originated in the United States (n=49), were original articles (n=87), used computed tomography (n=66), and were based on the topic of pulmonary thromboembolism (n=18). Department of Radiology, Mayo Clinic (n=7), and Department of Radiology, University of British Columbia and Vancouver General Hospital (n=7), were the leading institutions, and Müller NL (n=11) was the most prolific author. Our study lists the 100 top-cited articles in pulmonary imaging, provides an insight into historical developments, and allows for recognition of advances in this field.
[Survey of what is published on Italian nursing journals].

Nursing research is an important activity for nurses; the main aim is to improve the quality of nursing. Several national and european laws have been issued about it. To develop knowledge about nursing, nurses have to understand the results of researches, implement them in the different situation and sometimes carry out researches. The results can be published in nursing journals which a lot of nurses use to share information. This study reviewed the characteristics of research articles published in italian nursing journals from 1998 to 2003. Phenomena of interest are: areas of enquiry, investigators, methods, research design, sampling and means to gather data. 122 articles have been reviewed: 78% focus on clinical aspects, 55% were carry out by nurses, 92% adopt the quantitative approach, 90% used non experimental design, 89% used convenience selection sampling method and 58% answer ways. The characteristics of this study are similar to other studies about italian nursing publication. There are some limits in this type of literature: lower generalization because of lower representativeness of sample, convenience selection sampling method, and higher risk of interference due to frequent use of non experimental design. However the number of italian nurses that carry out researches is increasing and nursing is the most studied area.
A survey of the current status of web-based databases indexing Iranian journals.

The scientific output of Iran is increasing rapidly during the recent years. Unfortunately, most papers are published in journals which are not indexed by popular indexing systems and many of them are in Persian without English translation. This makes the results of Iranian scientific research unavailable to other researchers, including Iranians. The aim of this study was to evaluate the quality of current web-based databases indexing scientific articles published in Iran. We identified web-based databases which indexed scientific journals published in Iran using popular search engines. The sites were then subjected to a series of tests to evaluate their coverage, search capabilities, stability, accuracy of information, consistency, accessibility, ease of use, and other features. Results were compared with each other to identify strengths and shortcomings of each site. Five web sites were indentified. None had a complete coverage on scientific Iranian journals. The search capabilities were less than optimal in most sites. English translations of research titles, author names, keywords, and abstracts of Persian-language articles did not follow standards. Some sites did not cover abstracts. Numerous typing errors make searches ineffective and citation indexing unreliable. None of the currently available indexing sites are capable of presenting Iranian research to the international scientific community. The government should intervene by enforcing policies designed to facilitate indexing through a systematic approach. The policies should address Iranian journals, authors, and indexing sites. Iranian journals should be required to provide their indexing data, including references, electronically; authors should provide correct indexing information to journals; and indexing sites should improve their software to meet standards set by the government.

Cardiac ion channel modulation by the hypoglycaemic agent rosiglitazone.
Hancox, J C
2011-06-01
The hypoglycaemic thiazolidinedione rosiglitazone is used clinically in the treatment of type 2 diabetes. However, in 2010, information relating to rosiglitazone-associated increased cardiovascular risk led the European Medicines Agency to recommend suspension of marketing authorizations for rosiglitazone-containing anti-diabetes drugs, while the US Food and Drug Administration recommended significant restriction on the agent's use. Two timely studies in this issue of the British Journal of Phrarmacology provide new information regarding modification of cardiac cellular electrophysiology by rosiglitazone. Szentandrássy et al. demonstrate canine ventricular action potential modification and concentration-dependent suppression of L-type Ca current and of transient outward and rapid delayed rectifier K currents. Jeong et al. demonstrate concentration-dependent inhibition of recombinant K(v) 4.3 channels, providing mechanistic insight into the likely molecular basis of transient outward K current inhibition by the compound. Further studies using diabetic models would be of value to determine whether, in a diabetic setting, rosiglitazone modification of these channels could affect the risk of arrhythmia at clinically relevant drug concentrations. © 2011 The Author.

The number of citations that an article has received can be used to evaluate its impact on the scientific community. This study aimed to identify the 100 most cited articles in the field of neurointervention and to analyze their characteristics. We selected the 669 journals that were considered potentially to publish neurointervention articles based on the database of Journal Citation Reports. Using the Web of Science citation search tool, we identified the 100 most cited articles relevant to neurointervention within the selected journals. Each article was evaluated for several characteristics including publication year, journal, journal category, impact factor, number of citations, number of citations per year, authorship, department, institution, country, type of article, and topic. The number of citations for the top 100 articles ranged from 1912 to 170 (mean 363.4) and citations per year ranged from 271.0 to 4.1 (mean 40.0). The majority of articles were published in clinical neurology journals (63%), were published in 2000-2009 (39%), originated in the USA (45%), were original articles (95%), and dealt with endovascular treatment of cerebral aneurysm (42%). The Department of Radiology, University of California School of Medicine (n=12) was the leading institution and Viñuela F (n=11) was the most prolific author. Our study presents a detailed list and analysis of the 100 most cited articles in the field of neurointervention and provides a historical perspective on the scientific progress in this field.

An instrument to assess the statistical intensity of medical research papers.
Nieminen, Pentti; Virtanen, Jorma I; Vähänikkilä, Hannu
2017-01-01
There is widespread evidence that statistical methods play an important role in original research articles, especially in medical research. The evaluation of statistical methods and reporting in journals suffers from a lack of standardized methods for assessing the use of statistics. The objective of this study was to develop and evaluate an instrument to assess the statistical intensity in research articles in a standardized way. A checklist-type measure scale was developed by selecting and refining items from previous reports about the statistical contents of medical journal articles and from published guidelines for statistical reporting. A total of 840 original medical research articles that were published between 2007-2015 in 16 journals were evaluated to test the scoring instrument. The total sum of all items was used to assess the intensity between sub-fields and journals. Inter-rater agreement was examined using a random sample of 40 articles. Four raters read and evaluated the selected articles using the developed instrument. The scale consisted of 66 items. The total summary score adequately discriminated between research articles according to their study design characteristics. The new instrument could also discriminate between journals according to their statistical intensity. The inter-observer agreement measured by the ICC was 0.88 between all four raters. Individual item analysis showed very high agreement between the rater pairs, the percentage agreement ranged from 91.7% to 95.2%. A reliable and applicable instrument for evaluating the statistical intensity in research papers was developed. It is a helpful tool for comparing the statistical intensity between sub-fields and journals. The novel instrument may be applied in manuscript peer review to identify papers in need of additional statistical review.

Eye diseases with increasing mortality are common health problems that affect people of all ages and demographic backgrounds. In this study, we study the publication characteristics in international ophthalmic journals of the US, the UK, Germany, Australia, Japan, and China. Articles published in 53 ophthalmic journals from 2000 to 2011 were retrieved from the PubMed database. We recorded the number of articles published each year, analyzed the publication type, and evaluated the accumulated and average impact factors (IFs), and the distribution of articles in ophthalmic journals in relation to IFs. The characteristics of publication outputs from China and other top-ranking countries were compared. The total number of articles increased significantly during the past 12 years, with an increase of 51.0%. The growth in the annual number of articles from the US, the UK, Australia, and China showed a significantly positive trend. Publications from the US exceeded those from any other country and had the highest IFs, largest number of total citations of articles, and the most articles published in leading ophthalmic journals. During the past 12 years, China contributed 3.5% of the total publications, and the number of Chinese articles showed a more than 6-fold increase (from 99 to 605, R2 =0.947, P<0.001). The numbers of IFs and citations of articles originating in China were mostly lower than for other top-ranking counties. Research on ophthalmic journals has maintained an upward growing trend from 2000 to 2011. Chinese ophthalmology research has developed rapidly, but the gap still exists between China and other top-ranking countries for the advanced level of research.

A central tenet in support of research reproducibility is the ability to uniquely identify research resources, that is, reagents, tools, and materials that are used to perform experiments. However, current reporting practices for research resources are insufficient to identify the exact resources that are reported or to answer basic questions such as "How did other studies use resource X?" To address this issue, the Resource Identification Initiative was launched as a pilot project to improve the reporting standards for research resources in the methods sections of papers and thereby improve identifiability and scientific reproducibility. The pilot engaged over 25 biomedical journal editors from most major publishers, as well as scientists and funding officials. Authors were asked to include Research Resource Identifiers (RRIDs) in their manuscripts prior to publication for three resource types: antibodies, model organisms, and tools (i.e., software and databases). RRIDs are assigned by an authoritative database, for example, a model organism database for each type of resource. To make it easier for authors to obtain RRIDs, resources were aggregated from the appropriate databases and their RRIDs made available in a central web portal ( http://scicrunch.org/resources). RRIDs meet three key criteria: they are machine readable, free to generate and access, and are consistent across publishers and journals. The pilot was launched in February of 2014 and over 300 papers have appeared that report RRIDs. The number of journals participating has expanded from the original 25 to more than 40 with RRIDs appearing in 62 different journals to date. Here, we present an overview of the pilot project and its outcomes to date. We show that authors are able to identify resources and are supportive of the goals of the project. Identifiability of the resources post-pilot showed a dramatic improvement for all three resource types, suggesting that the project has had a significant impact on identifiability of research resources.

Scientometric data on the citation success of different publication types and publication genres in psychology publications are presented. Data refer to references that are cited in these scientific publications and that are documented in PSYNDEX, the exhaustive database of psychology publications from the German-speaking countries either published in German or in English language. Firstly, data analyses refer to the references that are cited in publications of 2009 versus 2010 versus 2011. With reference to all cited references, the portion of journal articles ranges from 57 to 61 %, of books from 22 to 24 %, and of book chapters from 14 to 15 %, with a rather high stability across the three publication years analysed. Secondly, data analyses refer to the numbers of cited references from the German-speaking countries, which are also documented in PSYNDEX. These compose about 11 % of all cited references indicating that nearly 90 % of the references cited are of international and/or interdisciplinary publications not stemming from the German-speaking countries. The subsample shows the proportion of journal articles, books, and chapters, and these are very similar to the percentages identified for all references that are cited. Thirdly, analyses refer to document type, scientific genre, and psychological sub-discipline of the most frequently cited references in the psychology publications. The frequency of top-cited references of books and book chapters is almost equal to that of journal articles; two-thirds of the top-cited references are non-empirical publications, only one-third are empirical publications. Top-cited references stem particularly from clinical psychology, experimental psychology, as well as tests, testing and psychometrics. In summary, the results point to the fact that citation analyses, which are limited to journal papers, tend to neglect very high portions of references that are cited in scientific publications.

A central tenet in support of research reproducibility is the ability to uniquely identify research resources, i.e., reagents, tools, and materials that are used to perform experiments. However, current reporting practices for research resources are insufficient to identify the exact resources that are reported or to answer basic questions such as "How did other studies use resource X?" To address this issue, the Resource Identification Initiative was launched as a pilot project to improve the reporting standards for research resources in the methods sections of papers and thereby improve identifiability and scientific reproducibility. The pilot engaged over 25 biomedical journal editors from most major publishers, as well as scientists and funding officials. Authors were asked to include Research Resource Identifiers (RRIDs) in their manuscripts prior to publication for three resource types: antibodies, model organisms, and tools (i.e., software and databases). RRIDs are assigned by an authoritative database, for example a model organism database, for each type of resource. To make it easier for authors to obtain RRIDs, resources were aggregated from the appropriate databases and their RRIDs made available in a central web portal ( http://scicrunch.org/resources ). RRIDs meet three key criteria: they are machine readable, free to generate and access, and are consistent across publishers and journals. The pilot was launched in February of 2014 and over 300 papers have appeared that report RRIDs. The number of journals participating has expanded from the original 25 to more than 40 with RRIDs appearing in 62 different journals to date. Here, we present an overview of the pilot project and its outcomes to date. We show that authors are able to identify resources and are supportive of the goals of the project. Identifiability of the resources post-pilot showed a dramatic improvement for all three resource types, suggesting that the project has had a significant impact on identifiability of research resources.

To investigate whether plagiarism is more prevalent in publications retracted from the medical literature when first authors are affiliated with lower-income countries versus higher-income countries. Secondary objectives included investigating other factors associated with plagiarism (e.g., national language of the first author's country affiliation, publication type, journal ranking). Systematic, controlled, retrospective, bibliometric study. Retracted publications dataset in MEDLINE (search filters: English, human, January 1966-February 2008). Retracted misconduct publications were classified according to the first author's country affiliation, country income level, and country national language, publication type, and ranking of the publishing journal. Standardised definitions and data collection tools were used; data were analysed (odds ratio [OR], 95% confidence limits [CL], chi-squared tests) by an independent academic statistician. Of the 213 retracted misconduct publications, 41.8% (89/213) were retracted for plagiarism, 52.1% (111/213) for falsification/fabrication, 2.3% (5/213) for author disputes, 2.3% (5/213) for ethical issues, and 1.4% (3/213) for unknown reasons. The OR (95% CL) of plagiarism retractions (other misconduct retractions as reference) were higher (P < 0.001) for first authors affiliated with lower-income versus higher-income countries (15.4 [4.5, 52.9]) and with non-English versus English national language countries (3.2 [1.8, 5.7]), for non-original research versus original research publications (8.4 [3.3, 21.3]), for case reports and series versus other original research types (4.2 [1.4, 13.0]), and for publications in low-ranked versus high-ranked journals (4.9 [2.4, 9.9]). Up until 2012, there were significantly (P < 0.007) fewer 'serial offenders' (first authors with >1 retraction) with publications retracted for plagiarism (11.5%, 9/78) than other types of misconduct (28.9%, 24/83). This is the first study to demonstrate that publications retracted for plagiarism are significantly associated with first authors affiliated with lower-income countries. These findings have implications for developing appropriate evidence-based strategies and allocation of resources to help mitigate plagiarism misconduct.

To compare the methodologic quality and study/report characteristics between quantitative clinical nursing and nursing education research articles. The methodologic quality of quantitative nursing education research needs to advance to a higher level. Clinical research can provide guidance for nursing education to reach this level. One hundred quantitative clinical research articles from-high impact journals published in 2007 and 37 education research articles from high impact journals published in 2006 to 2007 were chosen for analysis. Clinical articles had significantly higher quality scores than education articles in three domains: number of institutions studied, type of data, and outcomes. The findings indicate three ways in which nursing education researchers can strengthen the methodologic quality of their quantitative research. With this approach, greater funding may be secured for advancing the science of nursing education.

Rationale This study aimed to investigate the quality of reporting of anesthesia and euthanasia in experimental studies in small laboratory mammals published in the top ten impact factor journals. Methods A descriptive systematic review was conducted and data was abstracted from the ten highest ranked journals with respect to impact factor in the categories ‘Anesthesiology’, ‘Critical Care Medicine’ and ‘Respiratory System’ as defined by the 2012 Journal Citation Reports. Inclusion criteria according to PICOS criteria were as follows: 1) population: small laboratory mammals; 2) intervention: any form of anesthesia and/or euthanasia; 3) comparison: not specified; 4) primary outcome: type of anesthesia, anesthetic agents and type of euthanasia; secondary outcome: animal characteristics, monitoring, mechanical ventilation, fluid management, postoperative pain therapy, animal care approval, sample size calculation and performed interventions; 5) study: experimental studies. Anesthesia, euthanasia, and monitoring were analyzed per performed intervention in each article. Results The search yielded 845 articles with 1,041 interventions of interest. Throughout the manuscripts we found poor quality and frequency of reporting with respect to completeness of data on animal characteristics as well as euthanasia, while anesthesia (732/1041, 70.3%) and interventions without survival (970/1041, 93.2%) per se were frequently reported. Premedication and neuromuscular blocking agents were reported in 169/732 (23.1%) and 38/732 (5.2%) interventions, respectively. Frequency of reporting of analgesia during (117/610, 19.1%) and after painful procedures (38/364, 10.4%) was low. Euthanasia practice was reported as anesthesia (348/501, 69%), transcardial perfusion (37/501, 8%), carbon dioxide (26/501, 6%), decapitation (22/501, 5%), exsanguination (23/501, 5%), other (25/501, 5%) and not specified (20/501, 4%, respectively. Conclusions The present systematic review revealed insufficient reporting of anesthesia and euthanasia methods throughout experimental studies in small laboratory mammals. Specific guidelines for anesthesia and euthanasia regimens should be considered to achieve comparability, quality of animal experiments and animal welfare. These measures are of special interest when translating experimental findings to future clinical applications. PMID:26305700

The similarity between the psychological features of medical school freshmen of different cohorts suggests that Medicine attracts students with specific psychological types. However, it is also possible that medical students are similar to the students admitted to any other career with high admission requirements. To determine if medical school freshmen are different from those of Engineering, Architecture, Psychology and Journalism. The Spanish version of the Myers Briggs Psychological Type Indicator (MBTI) was applied to two cohorts of Medical School freshmen (90 students of the 2000 cohort and 91 students of the 2001 cohort) and to a sample of 669 freshmen from the careers of Engineering, Psychology, Architecture and Journalism. Students entering Medical School are similar to the students admitted to Engineering and different from those that entered Architecture, Psychology and Journalism in the Pontificia Universidad Católica de Chile in 2000 and 2001. Medicine attracts a larger proportion of concrete and practical students that have an objective and systematic approach to study and to life in general. Unlike Medicine, Psychology and Architecture attract more students that have a cognitive style characterized by an intuitive perception, and that face life with an open and flexible attitude. This study reveals that the psychological features of undergradutate students are associated to their career choice. These psychological variables, therefore, may be relevant to the students' vocational preferences and possibly to their future specialty choice.

Describe the prevalence and types of conflicts of interest (COI) in published randomized controlled trials (RCTs) in general medical journals with a binary primary outcome and assess the association between conflicts of interest and favorable outcome. Parallel-group RCTs with a binary primary outcome published in three general medical journals during 2013-2015 were identified. COI type, funding source, and outcome were extracted. Binomial logistic regression model was performed to assess association between COI and funding source with outcome. A total of 509 consecutive parallel-group RCTs were included in the study. COI was reported in 74% in mixed funded RCTs and in 99% in for-profit funded RCTs. Stock ownership was reported in none of the non-profit RCTs, in 7% of mixed funded RCTs, and in 50% of for-profit funded RCTs. Mixed-funded RCTs had employees from the funding company in 11% and for-profit RCTs in 76%. Multivariable logistic regression revealed that stock ownership in the funding company among any of the authors was associated with a favorable outcome (odds ratio = 3.53; 95% confidence interval = 1.59-7.86; p < 0.01). COI in for-profit funded RCTs is extensive, because the factors related to COI are not fully independent, a multivariable analysis should be cautiously interpreted. However, after multivariable adjustment only stock ownership from the funding company among authors is associated with a favorable outcome.

To appraise the current reporting methodological quality of randomized clinical trials (RCTs) in 3 leading diabetes journals.We systematically searched the literature for RCTs in Diabetes Care, Diabetes and Diabetologia from 2011 to 2013.Characteristics were extracted based on Consolidated Standards of Reporting Trials (CONSORT) statement. Generation of allocation, concealment of allocation, intention-to-treat (ITT) analysis and handling of dropouts were defined as primary outcome and "low risk of bias." Sample size calculation, type of intervention, country, number of patients, funding source were also revealed and descriptively reported. Trials were compared among journals, study years, and other characters.A total of 305 RCTs were enrolled in this study. One hundred eight (35.4%) trials reported adequate generation of allocation, 87 (28.5%) trials reported adequate concealment of allocation, 53 (23.8%) trials used ITT analysis, and 130 (58.3%) trials were adequate in handling of dropouts. Only 15 (4.9%) were "low risk of bias" trials. Studies at a large scale (n > 100) or from European presented with more "low risk of bias" trials than those at a small scale (n ≤ 100) or from other regions. No improvements were found in these 3 years.This study shows that methodological reporting quality of RCTs in the major diabetes journals remains suboptimal. It can be further improved to meet and keep up with the standards of the CONSORT statement.

To identify global research trends in the use of acupuncture to treat cerebral infarction. We performed a bibliometric analysis of studies on the use of acupuncture to treat cerebral infarction published during 2002-2011, retrieved from Scopus, using the key words of acupuncture and cerebral infarction or ischemic stroke. peer-reviewed articles on the use of acupuncture to treat cerebral infarction indexed in Scopus and published between 2002 and 2011; types of publications were original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items. articles that required manual searching or telephone access; documents that were not published in the public domain; and corrected papers. (a) Annual publication output; (b) language of publication; (c) type of publication; (d) key words of publication; (e) publication by research field; (f) publication by journal; (g) publication by country and institution; (h) publication by author; (i) most-cited papers between 2002 and 2006; and (j) most-cited papers between 2007 and 2011. A total of 160 publications on the use of acupuncture to treat cerebral infarction from 2002-2011 were retrieved from Scopus. The number of publications increased gradually over the 10-year study period; most were written in Chinese or English. Articles and reviews constituted the major types. The most frequent key word used was acupuncture. The most prolific journals in this area were Zhongguo Zhen Jiu and the Chinese Journal of Clinical Rehabilitation. Of the 160 publications retrieved, half came from Chinese authors and institutions. Tianjin University of Traditional Chinese Medicine was the most prolific research institute. Two papers were cited 30 times; they were published in 2002 and 2009, respectively. In the field of neuroscience, there is little literature on acupuncture for cerebral infarction. The most-cited papers were cited 30 times in the past 3 years. We believe that, with advances in the study of mechanisms in neurobiology, research on acupuncture will also advance and will become the concern of more scholars.

To address the bias occurring in the medical literature associated with selective outcome reporting, in 2005, the International Committee of Medical Journal Editors (ICMJE) introduced mandatory trial registration guidelines and member journals required prospective registration of trials prior to patient enrolment as a condition of publication. No research has examined whether these guidelines are impacting psychiatry publications. Our objectives were to determine the extent to which articles published in psychiatry journals adhering to ICMJE guidelines were correctly prospectively registered, whether there was evidence of selective outcome reporting and changes to participant numbers, and whether there was a relationship between registration status and source of funding. Any clinical trial (as defined by ICMJE) published between 1 January 2009 and 31 July 2013 in the top five psychiatry journals adhering to ICMJE guidelines (The American Journal of Psychiatry, Archives of General Psychiatry/JAMA Psychiatry, Biological Psychiatry, Journal of the American Academy of Child and Adolescent Psychiatry, and The Journal of Clinical Psychiatry) and conducted after July 2005 (or 2007 for two journals) was included. For each identified trial, where possible we extracted trial registration information, changes to POMs between publication and registry to assess selective outcome reporting, changes to participant numbers, and funding type. Out of 3305 articles, 181 studies were identified as clinical trials requiring registration: 21 (11.6%) were deemed unregistered, 61 (33.7%) were retrospectively registered, 37 (20.4%) had unclear POMs either in the article or the registry and 2 (1.1%) were registered in an inaccessible trial registry. Only 60 (33.1%) studies were prospectively registered with clearly defined POMs; 17 of these 60 (28.3%) showed evidence of selective outcome reporting and 16 (26.7%) demonstrated a change in participant numbers of 20% or more; only 26 (14.4%) of the 181 the trials were prospectively registered and did not alter their POMs or the time frames at which they were measured. Prospective registration with no changes in POMs occurred more frequently with pharmaceutical funding. Although standards are in place to improve prospective registration and transparency in clinical trials, less than 15% of psychiatry trials were prospectively registered with no changes in POMs. Most trials were either not prospectively registered, changed POMs or the timeframes at some point after registration or changed participant numbers. Authors, journal editors and reviewers need to further efforts to highlight the value of prospective trial registration.

Research in statistical methods is essential for maintenance of high quality of the published literature. To update previous reports of the types and frequencies of statistical terms and procedures in research studies of selected professional pharmacy journals. We obtained all research articles published in 2001 in 6 journals: American Journal of Health-System Pharmacy, The Annals of Pharmacotherapy, Canadian Journal of Hospital Pharmacy, Formulary, Hospital Pharmacy, and Journal of the American Pharmaceutical Association. Two independent reviewers identified and recorded descriptive and inferential statistical terms/procedures found in the methods, results, and discussion sections of each article. Results were determined by tallying the total number of times, as well as the percentage, that each statistical term or procedure appeared in the articles. One hundred forty-four articles were included. Ninety-eight percent employed descriptive statistics; of these, 28% used only descriptive statistics. The most common descriptive statistical terms were percentage (90%), mean (74%), standard deviation (58%), and range (46%). Sixty-nine percent of the articles used inferential statistics, the most frequent being chi(2) (33%), Student's t-test (26%), Pearson's correlation coefficient r (18%), ANOVA (14%), and logistic regression (11%). Statistical terms and procedures were found in nearly all of the research articles published in pharmacy journals. Thus, pharmacy education should aim to provide current and future pharmacists with an understanding of the common statistical terms and procedures identified to facilitate the appropriate appraisal and consequential utilization of the information available in research articles.

Evidence to inform clinical practice is reliant on research carried out using appropriate study design. The objectives of this work were to (i) identify the prevalence of articles reporting on human studies using uncontrolled intervention or observational research designs published in peer-reviewed dental journals and (ii) determine the nature of recommendations made by these articles. Six peer-reviewed dental journals were selected. Issues published in January to June 2013 were examined and the types of articles published categorized. Following pre-defined inclusion/exclusion criteria, human studies classified as using uncontrolled intervention or observational research designs were subject to detailed review by two independent investigators, to examine if they presented clinical, policy or research recommendations and if these recommendations were supported by the data presented. 52.9% (n = 156) of studies published during the time period met the inclusion criteria. Studies with uncontrolled intervention or observational research designs comprised a larger proportion of the primary research studies published in the journals with lower impact factors (73.3%; n = 107) compared to the high impact journals (38.9%; n = 49). Analysis showed that 60.9% (n = 95) of the included studies made recommendations for clinical practice/dental policy. In 28.2% (n = 44) of studies, the clinical/policy recommendations made were judged to not be fully supported by the data presented. Many studies published in the current dental literature, which are not considered to produce strong evidence, make recommendations for clinical practice or policy. There were some cases when the recommendations were not fully supported by the data presented. Copyright © 2016 Elsevier Inc. All rights reserved.

Background Investigations into the factors behind coauthorship growth in biomedical research have mostly focused on specific disciplines or journals, and have rarely controlled for factors in combination or considered changes in their effects over time. Observers often attribute the growth to the increasing complexity or competition (or both) of research practices, but few attempts have been made to parse the contributions of these two likely causes. Objectives We aimed to assess the effects of complexity and competition on the incidence and growth of coauthorship, using a sample of the biomedical literature spanning multiple journals and disciplines. Methods Article-level bibliographic data from PubMed were combined with publicly available bibliometric data from Web of Science and SCImago over the years 1999–2007. We selected four predictors of coauthorship were selected, two (study type, topical scope of the study) associated with complexity and two (financial support for the project, popularity of the publishing journal) associated with competition. A negative binomial regression model was used to estimate the effects of each predictor on coauthorship incidence and growth. A second, mixed-effect model included the journal as a random effect. Results Coauthorship increased at about one author per article per decade. Clinical trials, supported research, and research of broader scope produced articles with more authors, while review articles credited fewer; and more popular journals published higher-authorship articles. Incidence and growth rates varied widely across journals and were themselves uncorrelated. Most effects remained statistically discernible after controlling for the publishing journal. The effects of complexity-associated factors held constant or diminished over time, while competition-related effects strengthened. These trends were similar in size but not discernible from subject-specific subdata. Conclusions Coauthorship incidence rates are multifactorial and vary with factors associated with both complexity and competition. Coauthorship growth is likewise multifactorial and increasingly associated with research competition. PMID:28329003

Cryogenic fluids in isothermal rigid surface and foil type journal bearings can sometimes be treated as semicompressible fluids. In these applications, the fluid density is a function of the pressure. At low pressures, the fluids can change from a liquid to a saturated liquid-vapor phase. The performance of a rigid surface journal bearing with an idealized semicompressible fluid is discussed. Pressure solutions are based upon a Reynolds equation which includes the effects of a compressibility via the bulk modulus of the fluid. Results are contrasted with the performance of isothermal constant property incompressible fluids.
Scientific journals and their authors' financial interests: a pilot study.

The credibility of modern science is grounded on the perception of the objectivity of its scientists, but that credibility can be undermined by financial conflicts of interest. The US Public Health Service and the National Science Foundation issued regulations effective October 1, 1995, regarding the disclosure of financial interests in the submission of grant proposals. Several scientific journals have also established pertinent policies for authors and editors. The objectives of this study were: (1) to select a set of published articles and observe the degree to which a sample of authors hold a financial interest in areas related to their research that are reportable under current standards, and (2) to examine the hypothesis that significant numbers of authors of articles in life science and biomedical journals have verifiable financial interests that might be important for journal editors and readers to know. This paper measures the frequency of selected financial interests held among lead authors of certain types of scientific publications and assesses disclosure practices of authors and journals. These objectives were applied to a pilot study of Massachusetts academic scientists who were cited as first or last author in at least one article published in 1992 in 14 leading journals of cell or molecular biology and medicine. We created a database of every original article published in 1992 by 14 leading life science and biomedical journals, supplemented by data sets consisting of (1) Massachusetts biotechnology firms, including their officers and scientific advisory boards, and (2) scientists listed as inventors on patents or patent applications registered with the World Intellectual Property Organization. We examined 1,105 university authors (first and last cited) from Massachusetts institutions whose 789 articles, published in 1992, appeared in 14 scientific and medical journals. Authors are said to 'possess a financial interest' if they are listed as inventors in a patent or patent application closely related to their published work; serve on a scientific advisory board of a biotechnology company; or are officers, directors, or major shareholders (beneficial owner of 10% or more of stock issued) in a firm that has commercial interests related to their research. Applying the criteria to the reference population of journals and Massachusetts academic authors, we measured the following frequencies for lead authors: 0.20 for serving on a scientific advisory board; 0.07 for being an officer, director, or major shareholder in a biotechnology firm, and 0.22 for being listed as an inventor in a related patent or patent application. The joint frequency of articles in the journals reviewed with a lead author that meets one of the three conditions is 0.34. One of every three articles in our sample has at least one Massachusetts-based author with a financial interest, and 15% of the authors in our sample have a financial interest relevant to one of their publications. For the year 1992, the rate of published voluntary disclosures of financial interest (as defined in our study) is virtually zero, but relatively few scientific and biomedical journals at that time required any such disclosure to journal editors and reviewers. Further research is needed to determine the effectiveness of mandatory disclosure requirements by some journals.

Publication of a study is the end point of the process to contribute to the literature and confirm the scientific value of the study. Publication rates of the abstracts presented at the annual meetings of neurosurgery have been studied, previously. However, publication rates of the abstracts presented at the annual meetings of pediatric neurosurgery have not been reported, yet. We evaluated abstracts presented at the 38th annual meeting of the International Society for Pediatric Neurosurgery (ISPN) held in South Korea, 2010. We conducted this cross-sectional study by reviewing the abstracts presented at the annual meeting of the ISPN, 2010. Titles and authors of the abstracts were surveyed using Google Scholar and PubMed/MEDLINE. Time to publication, origin of the study, journal name in which the study has been accepted and published, and type of study has been analyzed for each abstract. The abstract booklet included 235 abstracts, consisted of 128 oral presentations (54%) and 107 electronic posters (46%). Fifty-nine (46%) of the oral presentations were published in a peer-reviewed journal. Laboratory studies were more likely to be published when compared to the clinical studies (72 vs. 39%). Thirty-two (30%) of the electronic posters were published in peer-reviewed journals. Most of the published abstracts were from Asia and Europe. Most of the abstracts were published in Child's Nervous System and Journal of Neurosurgery: Pediatrics. Publication rates of the abstracts presented at annual meeting of the ISPN were comparable to the other similar congresses. Oral presentations were more likely to be published. High publication rates of the abstracts presented at the annual meeting of the ISPN suggested that the meeting had a high scientific value.

Having sufficient power to detect effect sizes of an expected magnitude is a core consideration when designing studies in which inferential statistics will be used. The main aim of this study was to investigate the statistical power in studies published in the International Journal of Mental Health Nursing. From volumes 19 (2010) and 20 (2011) of the journal, studies were analysed for their power to detect small, medium, and large effect sizes, according to Cohen's guidelines. The power of the 23 studies included in this review to detect small, medium, and large effects was 0.34, 0.79, and 0.94, respectively. In 90% of papers, no adjustments for experiment-wise error were reported. With a median of nine inferential tests per paper, the mean experiment-wise error rate was 0.51. A priori power analyses were only reported in 17% of studies. Although effect sizes for correlations and regressions were routinely reported, effect sizes for other tests (χ(2)-tests, t-tests, ANOVA/MANOVA) were largely absent from the papers. All types of effect sizes were infrequently interpreted. Researchers are strongly encouraged to conduct power analyses when designing studies, and to avoid scattergun approaches to data analysis (i.e. undertaking large numbers of tests in the hope of finding 'significant' results). Because reviewing effect sizes is essential for determining the clinical significance of study findings, researchers would better serve the field of mental health nursing if they reported and interpreted effect sizes. © 2012 The Authors.

The objective of this study was to examine the type and content of Journal of Women's Health Physical Therapy (JWHPT) publications over the last decade. Content and bibliometric analysis of published literature. Component sections, such as the Section on Women's Health (SoWH) of the American Physical Therapy Association provide content expertise to areas of specialty physical therapist practice, thereby supporting the dissemination of evidence for physical therapists to use. Closely aligned with the mission of the SoWH, JWHPT provides evidence reflecting this practice area. The purpose of our analysis was to examine publications within JWHPT to determine how closely JWHPT is meeting the mission and focus of section members. We used established bibliographic methodology to code and review manuscripts published online between 2005 and 2015 in JWHPT using established domains (article type, participant type, research design, study purpose, and area of focus). Total publications and proportion of publications based on domain were described. Impact by citation and author was examined using bibliometric software. Eighteen percent of the items published in JWHPT were original research papers submitted for the first time. Of those papers, the primary study design was cross-sectional experimental research, most commonly studying interventions. The primary practice area reported was management of incontinence. We suggest that a continued need to increase efforts for the submission and publication of a greater proportion of randomized controlled trials and metric articles.

INTRODUCTION The scientific production of institutions of higher education, as well as the dissemination and use of this published work by peer institutions, can be assessed by means of quantitative and qualitative measurements. This type of analysis can also serve as the basis of further academic actions. Variables such as the type of evaluation, the number of faculty members and the decision to include or exclude researchers who are not professors are difficult to measure when comparing different schools and institutions. OBJECTIVES The purpose of this study was to assess the scientific production of tenured faculty from the Universidade de São Paulo, Faculdade de Medicina performed from 2001 to 2006. METHODS Medline/PubMed database was considered and the Impact factors (IFs - Journal Citation Report, 2006) and the number of generated citations (Web of Science/ISI Thomson) were also evaluated. RESULTS The analysis of the scientific production of 66 full professors (level MS-6) revealed 1,960 scientific articles published in 630 scientific journals, of which 31.3% were Brazilian and 68.7% were from international sources. Among these, 47% of the articles were published in 62.9% of the journals with IFs above 10, although 16.4% of the journals did not have assigned IF values. We verified that 45% of the published articles received 9,335 citations (average of 11 + 17), with the majority of these (8,968 citations) appearing in international scientific journals. CONCLUSIONS Our results indicate that it is possible to analyze the scientific production of a learning institution by the number of papers published by full professors, taking into account not only their academic position and influence, but also the fact that publication is an opportunity to stimulate joint projects with other members of the same institution.

Background Peer review is considered crucial to the selection and publication of quality science, but very little is known about the previous experiences and training that might identify high-quality peer reviewers. The reviewer selection processes of most journals, and thus the qualifications of their reviewers, are ill defined. More objective selection of peer reviewers might improve the journal peer review process and thus the quality of published science. Methods and Findings 306 experienced reviewers (71% of all those associated with a specialty journal) completed a survey of past training and experiences postulated to improve peer review skills. Reviewers performed 2,856 reviews of 1,484 separate manuscripts during a four-year study period, all prospectively rated on a standardized quality scale by editors. Multivariable analysis revealed that most variables, including academic rank, formal training in critical appraisal or statistics, or status as principal investigator of a grant, failed to predict performance of higher-quality reviews. The only significant predictors of quality were working in a university-operated hospital versus other teaching environment and relative youth (under ten years of experience after finishing training). Being on an editorial board and doing formal grant (study section) review were each predictors for only one of our two comparisons. However, the predictive power of all variables was weak. Conclusions Our study confirms that there are no easily identifiable types of formal training or experience that predict reviewer performance. Skill in scientific peer review may be as ill defined and hard to impart as is “common sense.” Without a better understanding of those skills, it seems unlikely journals and editors will be successful in systematically improving their selection of reviewers. This inability to predict performance makes it imperative that all but the smallest journals implement routine review ratings systems to routinely monitor the quality of their reviews (and thus the quality of the science they publish).

The aim of the study was to analyze the 100 most cited publications with Turkish origin in the Web of Science Otorhinolaryngology (ORL) journals. The Web of Science database was searched in terms of citations for publications originating from Turkey in ORL journals since 1983. After the identification of the 100 most cited articles, analysis was performed for the first author, institution, city, publication type, subject related to subspecialty, and journals having the most cited articles. Moreover, the number of ORL publications and citations of countries was determined in descending order using the same database. A total of 3948 ORL articles with Turkish origin was identified. The number of citations was 181 for the first and 28 for the last in the 100 most cited articles. As there was more than one article with 28 citations, 101 articles were analyzed. The number of the articles was 76, 22, and 3 for the university, education/research, and state hospitals, respectively. Hacettepe University, Ankara Numune Hospital, and Gazi University were the three leading institutions having the most cited articles, and Ankara was the first city. While 98 of 101 articles were original research, the number of case reports and review articles were 2 and 1, respectively. Thirty-five articles were related to otology, 23 to pediatric ORL, 20 to rhinology and head and neck surgery, and 3 to facial plastic surgery. Laryngoscope, Otolaryngology-Head and Neck Surgery, and International Journal of Pediatric Otorhinolaryngology were the leading 3 journals with the most cited articles coming from Turkey. The evaluation of countries revealed that Turkey was among the first 10 countries in terms of number of ORL articles but fell behind for the number of citations. This bibliometric study is the first one regarding the contribution of Turkish authors and institutions to ORL literature. Similar studies might be periodically repeated to determine national development in the field of ORL and place of Turkey in the world.

Background Randomized controlled trials (RCTs) are important sources of information on the benefits and harms patients may expect from treatment options. The aim of this structured literature review by the German Institute for Quality and Efficiency in Health Care was to explore whether and how the end-of-life (EoL) situation of patients with advanced cancer is considered in RCTs investigating anti-cancer treatments. Methods Our journal pool comprised 19 medical journals, namely five preselected key general medical journals as well as 14 specialist journals (mainly cancer) identified via a scoping search. We systematically searched these journals in MEDLINE to identify RCTs investigating anti-cancer treatments for the following four cancer types: glioblastoma, lung cancer (stage IIIb-IV), malignant melanoma (stage IV), and pancreatic cancer (search via OVID; November 2012). We selected a representative sample of 100 publications, that is, the 25 most recent publications for each cancer type. EoL was defined as a life expectancy of ≤ two years. We assessed the information provided on (1) the descriptions of the terminal stage of the disease, (2) the therapeutic goal (i.e. the intended therapeutic benefit of the intervention studied), (3) the study endpoints assessed, (4) the authors’ concluding appraisal of the intervention’s effects, and (5) the terminology referring to the patients’ EoL situation. Results Median survival was ≤ one year for each of the four cancer types. Descriptions of the terminal stage of the disease were ambiguous or lacking in 29/100 publications. One or more therapeutic goals were mentioned in 51/100 publications; these goals were patient-relevant in 38 publications (survival alone: 30/38; health-related quality of life (HRQoL) or HRQoL and survival: 6/38; symptom control or symptom control and survival: 2/38). Primary endpoints included survival (50%), surrogates (44%), and safety (3%). Patient-reported outcomes (PROs) were assessed in 36/100 RCTs. The implications of treatment-related harms for the patients were discussed in 22/100 appraisals. Terminology referring to the patients’ EoL situation (e.g. “terminal”) was scarce, whereas terms suggesting control of the disease (e.g. “cancer control“) were common. Conclusions The EoL situation of patients with advanced cancer should be more carefully considered in clinical trials. Although the investigation and robust reporting of PROs is a prerequisite for informed decision-making in healthcare, they are rarely defined as endpoints and HRQoL is rarely mentioned as a therapeutic goal. Suggestions for improving standards for study design and reporting are presented. PMID:26327232

To characterize the scientific output of the Revista Panamericana de Salud Pública/Pan American Journal of Public Health (RPSP) as a scientific publication of reference in the public health sector in the Americas. A descriptive cross-sectional study was conducted based on the articles published in the RPSP from 1997-2012. Bibliometric indicators of productivity (documents published, languages, authorship, and indices of productivity and collaboration); impact (impact factor according to the SciELO Network, Journal Citation Report and SCImago); key words; and bibliographic references, their structure (document type and main nucleus of Bradford) and degree of obsolescence (Burton and Kebler half-life, and Price index), were analyzed. A total of 2 815 articles with a median of 3 authors and 2 institutions per article were published. The percentage of original research articles increased in 2008-2012 compared to 2003-2007 and 1997-2002 (P < 0.001). The predominant language was Spanish, displaced by English in the last 5 years. A total of 88.76% of the key words referred to the Health Sciences Descriptors (DeCS) and had a public health and community orientation related to the Americas. The Burton and Kebler half-life of bibliographic references was 8 years, although it decreased to 5 years in 2012. The Price index was 20.47% and the nucleus of Bradford was made up of 20 mainstream journals. The percentage of self-citation was low (2.07%). The RPSP is an international publication with bibliometric indicators similar to those of the most representative Latin American health science journals, with improvements in the recent years studied that lead it to fully meet international publishing criteria.

IntroductionPeripheral arterial disease (PAD) is being increasingly managed by endovascular therapies. In this study, we identified the clinical services publishing research as well as the journals of publication over a 5-year period.MethodsTwenty keywords and phrases related to endovascular intervention were identified, and a literature search was performed through the PubMed database from January 2009 to January 2014. Inclusion criteria were English language, study population more than five patients, and matching the keyword search. Eligible studies were collated into a database and classified by journal of publication, PubMed number, article title, publishing clinical service, type of publication, country of origin, andmore » authors.Results825 studies from 114 different journals were identified. 297 papers were excluded. Of the 528 included papers, 204 (39%) were published by Vascular Surgery (VS), 157 (30%) by Interventional Radiology (IR), 101 (19%) by Cardiology, 43 (8%) by Angiology, 6 (1%) by Vascular Medicine, and 17 (3%) from miscellaneous services. 283 (54%) studies originated from Europe, 157 (30%) from North America, 76 (14%) from Asia, 6 from Australia, 3 each from South America and Africa. IR published the most papers on PAD endovascular intervention in Europe with VS second while this trend was reversed in the USA. The 528 papers were published in 98 different journals with retrospective case series (72%), the majority.ConclusionIR continues to play a significant research role in endovascular intervention in PAD, particularly in Europe, and specifically in below the knee intervention, pedal intervention, and drug-eluting technologies.« less

Background: The role of scientific journals in diffusion of data concerning researches in the field of Public Health Dentistry is of premier importance. Bibliometric analysis involves analysis of publications reflecting the type of research work. Aim: The present study was conducted with an aim to determine the number and trends of published articles in Journal of Clinical and Diagnostic Research (JCDR) from Feb. 2007 to Oct.2014. Settings and Design: A retrospective observational study was conducted for JCDR. Materials and Methods: All issues of JCDR were electronically searched for the parameters : study design, area of interest of research, state /college where research was conducted, authorship pattern, source of articles published each year, changing study trends, disease under study and publication bias. Statistical Analysis used: The data was organized and analyzed using software SPSS - version 21.0; descriptive statistics was used. Results: Bibliometric analysis was done for 601 articles of JCDR published from Feb. 2007 to Oct. 2014. The total number of articles published under Dentistry section have tremendously increased from mere 2 articles in 2007 to 328 articles in 2014.Majority of the study designs published in both the journal were case reports (42.6%) followed by cross sectional studies (24.8%). 96.3% of the articles were from India. Majority of the articles published were of multi authors (65.2%) and from Educational institutes (98.4%). The trends of the articles published indicated that the case reports/series formed the major bulk (others=59.1%) followed by research studies (21.3%). Conclusion: It was concluded that most articles published were case reports followed by researches indicating an inclination towards better quality methodology. The SJR and the citation count of the articles published also indicated the quality of the scientific articles published. PMID:26023643

Quality of claims and references found in Australian pharmacy journal advertisements.
Mandoh, Mona; Curtain, Colin Michael
2017-10-01
To evaluate the quality of pharmaceutical advertisement claims and supporting references in Australian pharmacy journals that target community pharmacists. All full-page advertisements for a medicinal product, found in two Australian pharmacy journals from the year 2012 to 2015 were included. Advertisement claims and references were evaluated by claim type (unambiguous to immeasurable) and level of evidence (strong to irrelevant) in supporting references. Two hundred and ninety distinct advertisements and 598 claims were identified, with a median of 2 claims per advertisement. Twenty-seven percent of claims were unambiguous, 40% were vague, 16% were emotive/immeasurable and 17% were non-clinical or other marketing claims. Half of all claims were referenced. Although 68% of unambiguous claims were referenced, 63% of those were supported by studies that were funded directly or indirectly by pharmaceutical companies. Only 13% of claims were supported with strong or moderate independent evidence. Pharmaceutical advertisements continue to present vague and emotive claims with little independent supporting evidence. Pharmacists need to be aware of these limitations when providing patient care. Increased awareness of this issue among pharmaceutical companies, Australian pharmaceutical journal publishers, regulators and pharmacists will assist in promoting optimised healthcare outcomes for the Australian public. © 2016 Royal Pharmaceutical Society.

This review of 88 articles in three international journals was undertaken for the purpose of investigating the methodology for perceptual speech assessment in patients with cleft palate. The articles were published between 1980 and 2000 in the Cleft Palate-Craniofacial Journal, the International Journal of Language and Communication Disorders, and Folia Phoniatrica et Logopaedica. The majority of articles (76) were published in the Cleft Palate-Craniofacial Journal, with an increase in articles during the 1990s and 2000. Information about measures or variables was clearly given in all articles. However, the review raises several major concerns regarding method for collection and documentation of data and method for measurement. The most distressing findings were the use of a cross-sectional design in studies of few patients with large age ranges and different types of clefts, the use of highly variable speech samples, and the lack of information about listeners and on reliability. It is hoped that ongoing national and international collaborative efforts to standardize procedures for collection and analysis of perceptual data will help to eliminate such concerns and thus make comparison of published results possible in the future.
Open Access Publishing in the Field of Medical Informatics.
Kuballa, Stefanie
2017-05-01
The open access paradigm has become an important approach in today's information and communication society. Funders and governments in different countries stipulate open access publications of funded research results. Medical informatics as part of the science, technology and medicine disciplines benefits from many research funds, such as National Institutes of Health in the US, Wellcome Trust in UK, German Research Foundation in Germany and many more. In this study an overview of the current open access programs and conditions of major journals in the field of medical informatics is presented. It was investigated whether there are suitable options and how they are shaped. Therefore all journals in Thomson Reuters Web of Science that were listed in the subject category "Medical Informatics" in 2014 were examined. An Internet research was conducted by investigating the journals' websites. It was reviewed whether journals offer an open access option with a subsequent check of conditions as for example the type of open access, the fees and the licensing. As a result all journals in the field of medical informatics that had an impact factor in 2014 offer an open access option. A predominantly consistent pricing range was determined with an average fee of 2.248 € and a median fee of 2.207 €. The height of a journals' open access fee did not correlate with the height of its Impact Factor. Hence, medical informatics journals have recognized the trend of open access publishing, though the vast majority of them are working with the hybrid method. Hybrid open access may however lead to problems in questions of double dipping and the often stipulated gold open access.

The aim of this study is to investigate the frequency of incorrect citations and its effects on the impact factor of a specific biomedical journal: the American Journal of Roentgenology. The Cited Reference Search function of Thomson Reuters' Web of Science database (formerly the Institute for Scientific Information's Web of Knowledge database) was used to identify erroneous citations. This was done by entering the journal name into the Cited Work field and entering "2011-2012" into the Cited Year(s) field. The errors in any part of the inaccurately cited references (e.g., author names, title, year, volume, issue, and page numbers) were recorded, and the types of errors (i.e., absent, deficient, or mistyped) were analyzed. Erroneous citations were corrected using the Suggest a Correction function of the Web of Science database. The effect of inaccurate citations on the impact factor of the AJR was calculated. Overall, 183 of 1055 citable articles published in 2011-2012 were inaccurately cited 423 times (mean [± SD], 2.31 ± 4.67 times; range, 1-44 times). Of these 183 articles, 110 (60.1%) were web-only articles and 44 (24.0%) were print articles. The most commonly identified errors were page number errors (44.8%) and misspelling of an author's name (20.2%). Incorrect citations adversely affected the impact factor of the AJR by 0.065 in 2012 and by 0.123 in 2013. Inaccurate citations are not infrequent in biomedical journals, yet they can be detected and corrected using the Web of Science database. Although the accuracy of references is primarily the responsibility of authors, the journal editorial office should also define a periodic inaccurate citation check task and correct erroneous citations to reclaim unnecessarily lost credit.
Bibliometric study of grey literature in core veterinary medical journals
Pelzer, Nancy L.; Wiese, William H.
2003-01-01
Objectives: Grey literature has been perceived by many as belonging to the primary sources of information and has become an accepted method of nonconventional communication in the sciences and medicine. Since little is known about the use and nature of grey literature in veterinary medicine, a systematic study was done to analyze and characterize the bibliographic citations appearing in twelve core veterinary journals. Methods: Citations from 2,159 articles published in twelve core veterinary journals in 2000 were analyzed to determine the portion of citations from grey literature. Those citations were further analyzed and categorized according to the type of publication. Results: Citation analysis yielded 55,823 citations, of which 3,564 (6.38%) were considered to be grey literature. Four veterinary specialties, internal medicine, pathology, theriogenology, and microbiology, accounted for 70% of the total number of articles. Three small-animal clinical practice journals cited about 2.5–3% grey literature, less than half that of journals with basic research orientations, where results ranged from almost 6% to approximately 10% grey literature. Nearly 90% of the grey literature appeared as conferences, government publications, and corporate organization literature. Conclusions: The results corroborate other reported research that the incidence of grey literature is lower in medicine and biology than in some other fields, such as aeronautics and agriculture. As in other fields, use of the Internet and the Web has greatly expanded the communication process among veterinary professionals. The appearance of closed community email forums and specialized discussion groups within the veterinary profession is an example of what could become a new kind of grey literature. PMID:14566374

A large number of morphological studies of intergranular carbides in steels have always been carried out in two dimensions without considering their dispersion manners. In this article, focused ion beam serial-sectioning tomography was carried out to study the correlation among the grain boundary characteristics, the morphologies and the dispersions of intergranular carbides in 347 austenitic stainless steel. More than hundred intergranular carbides were characterized in three dimensions and finally classified into three different types, two types of carbides probably semi-coherent to one of the neighboring grains with plate-type morphology, and one type of carbides incoherent to both grains with rod-type morphology. In addition, the rod-type carbide was found as the largest number of carbides among three types. Since large numbers of defects, such as misfit dislocations, may be present at the grain boundaries, which can be ideal nucleation sites for intergranular rod-type carbide precipitation. © The Author 2016.

Quantity and quality assessment of randomized controlled trials on orthodontic practice in PubMed.
Shimada, Tatsuo; Takayama, Hisako; Nakamura, Yoshiki
2010-07-01
To find current high-quality evidence for orthodontic practice within a reasonable time, we tested the performance of a PubMed search. PubMed was searched using publication type randomized controlled trial and medical subject heading term "orthodontics" for articles published between 2003 and 2007. The PubMed search results were compared with those from a hand search of four orthodontic journals to determine the sensitivity of PubMed search. We evaluated the precision of the PubMed search result and assessed the quality of individual randomized controlled trials using the Jadad scale. Sensitivity and precision were 97.46% and 58.12%, respectively. In PubMed, of the 277 articles retrieved, 161 (58.12%) were randomized controlled trials on orthodontic practice, and 115 of the 161 articles (71.42%) were published in four orthodontic journals: American Journal of Orthodontics and Dentofacial Orthopedics, The Angle Orthodontist, the European Journal of Orthodontics, and the Journal of Orthodontics. Assessment by the Jadad scale revealed 60 high-quality randomized controlled trials on orthodontic practice, of which 45 (75%) were published in these four journals. PubMed is a highly desirable search engine for evidence-based orthodontic practice. To stay current and get high-quality evidence, it is reasonable to look through four orthodontic journals: American Journal of Orthodontics and Dentofacial Orthopedics, The Angle Orthodontist, the European Journal of Orthodontics, and the Journal of Orthodontics.
Research Elements: new article types by Elsevier to facilitate reproducibility in science
NASA Astrophysics Data System (ADS)

When researchers start to make plans for new experiments, this is the beginning of a whole cycle of work, including experimental designs, tweaking of existing methods, developing protocols, writing code, collecting and processing experimental data, etc. A large part of this very useful information rarely gets published, which makes experiments difficult to reproduce. The same holds for experimental data, which is not always provided in a reusable format and lacks descriptive information. Furthermore, many types of data, such as a replication data, negative datasets or data from "intermediate experiments" often don't get published because they have no place in a research journal. To address this concern, Elsevier launched a series of peer-reviewed journal titles grouped under the umbrella of Research Elements (https://www.elsevier.com/books-and-journals/research-elements) that allow researchers to publish their data, software, materials and methods and other elements of the research cycle in a brief article format. To facilitate reproducibility, Research Elements have thoroughly thought out submission templates that include all necessary information and metadata as well as peer-review criteria defined per article type. Research Elements can be applicable to multiple research areas; for example, a number of multidisciplinary journals (Data in Brief, SoftwareX, MethodsX) welcome submissions from a large number of subject areas. At other times, these elements are better served within a single field; therefore, a number of domain-specific journals (e.g.: Genomics Data, Chemical Data Collections, Neurocomputing) support the new article formats, too. Upon publication, all Research Elements are assigned with persistent identifiers for direct citation and easy discoverability. Persistent identifiers are also used for interlinking Research Elements and relevant research papers published in traditional journals. Some Research Elements allow post-publication article updates. In the presentation, we will share our experiences and summarize lessons learned during the last two years. We will focus on three types of novel research publications: data articles, software articles and lab resources. We will also present two very recent developments targeting researchers working in Earth and Observational Sciences. And finally, we will illustrate how Research Elements fit in the Research Data Management landscape of a rich variety of services developed at Elsevier to assist researchers in sharing, finding, accessing, linking together and analyzing relevant research data.
Anesthesiology Journal club assessment by means of semantic changes.
Vieira, Joaquim Edson; Torres, Marcelo Luís Abramides; Pose, Regina Albanese; Auler, José Otávio Costa Junior
2014-01-01
the interactive approach of a journal club has been described in the medical education literature. The aim of this investigation is to present an assessment of journal club as a tool to address the question whether residents read more and critically. this study reports the performance of medical residents in anesthesiology from the Clinics Hospital - University of São Paulo Medical School. All medical residents were invited to answer five questions derived from discussed papers. The answer sheet consisted of an affirmative statement with a Likert type scale (totally disagree-disagree-not sure-agree-totally agree), each related to one of the chosen articles. The results were evaluated by means of item analysis - difficulty index and discrimination power. residents filled one hundred and seventy three evaluations in the months of December 2011 (n=51), July 2012 (n=66) and December 2012 (n=56). The first exam presented all items with straight statement, second and third exams presented mixed items. Separating "totally agree" from "agree" increased the difficulty indices, but did not improve the discrimination power. the use of a journal club assessment with straight and inverted statements and by means of five points scale for agreement has been shown to increase its item difficulty and discrimination power. This may reflect involvement either with the reading or the discussion during the journal meeting. Copyright © 2013 Sociedade Brasileira de Anestesiologia. Published by Elsevier Editora Ltda.

Looking like a criminal: stereotypical black facial features promote face source memory error.
Kleider, Heather M; Cavrak, Sarah E; Knuycky, Leslie R
2012-11-01
The present studies tested whether African American face type (stereotypical or nonstereotypical) facilitated stereotype-consistent categorization, and whether that categorization influenced memory accuracy and errors. Previous studies have shown that stereotypically Black features are associated with crime and violence (e.g., Blair, Judd, & Chapleau Psychological Science 15:674-679, 2004; Blair, Judd, & Fallman Journal of Personality and Social Psychology 87:763-778, 2004; Blair, Judd, Sadler, & Jenkins Journal of Personality and Social Psychology 83:5-252002); here, we extended this finding to investigate whether there is a bias toward remembering and recategorizing stereotypical faces as criminals. Using category labels, consistent (or inconsistent) with race-based expectations, we tested whether face recognition and recategorization were driven by the similarity between a target's facial features and a stereotyped category (i.e., stereotypical Black faces associated with crime/violence). The results revealed that stereotypical faces were associated more often with a stereotype-consistent label (Study 1), were remembered and correctly recategorized as criminals (Studies 2-4), and were miscategorized as criminals when memory failed. These effects occurred regardless of race or gender. Together, these findings suggest that face types have strong category associations that can promote stereotype-motivated recognition errors. Implications for eyewitness accuracy are discussed.

Joyce, Cormac W; Joyce, K M; Kelly, John C; Kelly, Jack L; Carroll, Sean M; Sugrue, Conor
2015-02-01
Over the past 50 years, there has been a significant increase in published articles in the medical literature. The aesthetic surgery literature is vast, consisting of a plethora of diverse articles written by a myriad of illustrious authors. Despite this considerable archive of published material, it remains nebulous as to which precise papers have had the greatest impact on our specialty. The aim of our study was to identify and analyse the characteristics of the top 50 papers in the field of aesthetic surgery in the published literature. The 50 most cited papers were identified in several surgical journals through the Web of Science. The articles were ranked in order of the number of citations received. These classic 50 papers were analysed for article type, their journal distribution, level of evidence as well as geographic and institutional origin. Six journals contributed to the top 50 papers in aesthetic surgery with Plastic and Reconstructive Surgery contributing the most with 31 papers.
Does our research tool kit equip us to make generalisable claims about dental education?
Chambers, D W
2012-11-01
In this essay on the state of scholarship in dental education, I argue that we are best served by looking at the validity, generalisability and usefulness of claims rather than at the rigour of various research methods. All papers published in 2009 in the European Journal of Dental Education (a quarterly) and the Journal of Dental Education (published monthly), a quarterly journal of the Academy of Management, Learning & Education and the monthly American Journal of Orthodontics and Dentofacial Orthopedics were classified by the type of claim made, method by which evidence was collected and techniques of analysis. The dental education literature, compared with the two other journals, was largely focussed on surveys of opinion or particular practices and lacked scope in generalisability. The dental education literature was thin in use of randomisation, covariable analysis and theory-building. © 2012 John Wiley & Sons A/S.

To investigate the research status of emergency medicine in China through literature search of international emergency medicine journals and retrospectively compare the outputs of emergency medicine articles of the 3 major regions of China-Mainland (ML), Taiwan (TW), and Hong Kong (HK). Emergency medicine journals were selected category from Science Citation Index Expand. Articles from the ML, TW, and HK were retrieved from PubMed database. The total number of articles, publication types, research contents, impact factors (IF), and articles published in each journal were conducted for quantity and quality comparisons. A total of 1760 articles from 19 emergency medicine journals were searched, of which 395 were from ML, 1210 from TW, and 155 from HK. Accumulated IF of articles from TW (2451.109) was much higher than that of ML (851.832) and HK (328.579), whereas the average IF of articles from TW (2.02) was the lowest. The number of case reports was the highest, which was, 69 from ML, 637 from TW, and 25 from HK, respectively. Although emergency medicine was involved with multiple organs and multiple systems, the reports of trauma accounted for 25% of the research contents. The total number of articles from both China and the rest of the world increased significantly from 2000 to 2014, especially ML. The total number of articles from TW was still much more than that of ML and HK, whereas the quality of articles from TW was not as good as ML and HK. Case report had the highest share of publication types, whereas the proportions of meta-analysis and observational study were the lowest. As for research contents, the proportion of trauma was still the highest. Copyright © 2015 Elsevier Inc. All rights reserved.

We have studied the magnetic behaviour of PrAu2(Si1-xGex)2 by means of magnetic susceptibility, resistivity, and heat capacity measurements, and x-ray and neutron powder diffraction. All compounds are isostructural and crystallize in the well known ThCr2Si2-type structure. PrAu2Si2 shows the characteristic features of a canonical spin glass with a freezing temperature of TF = 3 K. Completely unexpectedly, on introducing/increasing the atomic disorder by alloying with Ge, the spin-glass transition is suppressed as is first evident from a slight decrease of the freezing temperature TF up to x = 0.10. Long-range magnetic order sets in for xicons/Journals/Common/ge" ALT="ge" ALIGN="TOP"/>0.12. Within the range 0.15icons/Journals/Common/le" ALT="le" ALIGN="TOP"/> xicons/Journals/Common/le" ALT="le" ALIGN="TOP"/>1, all compounds show the same simple AF-I-type antiferromagnetic structure with a monotonic increase of both the Néel temperature and the ordered magnetic moment for increasing Ge concentration. The magnetic phase diagram of PrAu2(Si1-xGex)2 is explained by the presence of weak disorder at a constant level at the Au sites. Clear indications of crystal-field effects have been observed.

Objective The objective of this study was to examine the type and content of Journal of Women’s Health Physical Therapy (JWHPT) publications over the last decade. Study Design Content and bibliometric analysis of published literature Background Component sections, such as the Section on Women’s Health (SoWH) of the American Physical Therapy Association provide content expertise to areas of specialty physical therapist practice, thereby supporting the dissemination of evidence for physical therapists to use. Closely aligned with the mission of the SoWH, JWHPT provides evidence reflecting this practice area. The purpose of our analysis was to examine publications within JWHPT to determine how closely JWHPT is meeting the mission and focus of section members. Methods and Measures We used established bibliographic methodology to code and review manuscripts published online between 2005 and 2015 in JWHPT using established domains (article type, participant type, research design, study purpose, and area of focus). Total publications and proportion of publications based on domain were described. Impact by citation and author was examined using bibliometric software. Results Eighteen percent of the items published in JWHPT were original research papers submitted for the first time. Of those papers, the primary study design was cross-sectional experimental research, most commonly studying interventions. The primary practice area reported was management of incontinence. Conclusions We suggest that a continued need to increase efforts for the submission and publication of a greater proportion of randomized controlled trials and metric articles. PMID:29375281

To retrieve, summarize and analyze journals and articles related to acupuncture published in SCI periodicals in 2005, so as to understand the international dynamics about acupuncture researches. The articles about treatment and mechanisms of acupuncture published in SCI periodicals in 2005 were found out and searched for by acupuncture information retrieval online and databank. Most of the 72 SCI periodicals retrieved are from the west, with 147 articles of acupuncture published, and Lancet has the highest impact factors of 23. 407. The kinds of the journals and articles publishing acupuncture researches are increasing, with varied types, rich and varied contents, and increasing the design level. However, the results of the studies are vastly different due to differences of experimental methods, objects and acupuncture manipulations. Therefore, standardization of acupuncture studies is extremely urgent.

This poster describes future scenarios of information infrastructures in science and other fields of research. The scenarios presented are based on practical experience resulting from interaction with research data in a research center and its library, and further enriched by the results of a baseline study of existing data repositories and data infrastructures. The baseline study was conducted as part of the project "Requirements for a multi-disciplinary research data infrastructure (Radieschen)", which is funded by the German Research Foundation (DFG). Current changes in information infrastructures pose new challenges to libraries and scientific journals, which both act as information service providers, facilitating access to digital media, support publications of research data and enable their long-term archiving. Digital media and research data open new aspects in the field of activity of libraries and scientific journals. What will a library of the future look like? Will a library purely serve as interface to data centres? Will libraries and data centres merge into a new service unit? Will a future library be the interface to academic cloud services? Scientific journals already converted from mostly print editions to print and e-journals. What type of journals will emerge in the future? Is there a role for data-centred journals? Will there be journals to publish software code to make this type of research result citable and a part of the record of science? Just as users evolve from being consumers of information into producers, the role of information service providers, such as libraries, changes from a purely supporting to a contributing role. Furthermore, the role of the library changes from a central point of access for the search of publications to an important link in the value-adding chain from author to publication. Journals for software publication might be another vision for the future in data publishing. Software forms the missing link between big data collected by experiments, monitoring or simulation. In order to verify the results presented, a paper should also report on the process of data analysis applied to the data sets stored at data centers. In this case data, software, and interpretation supplement each other as a trustworthy, reproducible presentation of research results. Another approach is suggested by researchers of the EU-funded project "Liquid Publications" (1). Instead of traditional publications the researchers propose liquid journals as evolving collections of links and material, and recommend new methods in reviewing and assessing publications. Another point of interest are workflows in data publication. The commonly used model to depict the data life cycle might look appealing but does not necessarily represent reality. The model proposed by Treloar et. al. (2) offers a better approach to depict transition of research data between different domains of use, e.g. from the group domain to the public domain. However, several questions need to be addressed, such as how to avoid the loss of contextual information during transitions between domains, and the influence of the size of the data on the workflow process. This poster aims to present different scenarios of the future - from the point of view of researchers, libraries and scientific journals and will invite for further discussion.

Conflict of interest in oncology publications: a survey of disclosure policies and statements.
Kesselheim, Aaron S; Lee, Joy L; Avorn, Jerry; Servi, Amber; Shrank, William H; Choudhry, Niteesh K
2012-01-01
Disclosure of conflicts of interest in biomedical research is receiving increased attention. The authors sought to define current disclosure policies and how they relate to disclosure statements provided by authors in major oncology journals. The authors identified all oncology journals listed in the Thomson Institute for Scientific Information and sought their policies on conflict-of-interest disclosure. For a subset of journals with an Impact Factor >2.0, they catalogued the number and type of articles and the details of the published disclosures in all papers from the 2 most recent issues. Disclosure policies were provided by 112 of 131 journals (85%); 99 (88%) of these requested that authors disclose conflicts of interest (mean Impact Factor for these journals: 4.6), whereas the remaining 13 (12%) did not (mean Impact Factor: 2.9). Ninety-three journals (94%) required financial disclosure, and 42 (42%) also sought nonfinancial disclosures. For a subset of 52 higher-impact journals (Impact Factor >2.0), we reviewed 1734 articles and identified published disclosures in 51 journals (98%). Many of these journals (31 of 51, 61%) included some disclosure statement in >90% of their articles. Among 27 journals that published editorials/commentaries, only 14 (52%) included disclosures with such articles. There was no publication of any nonfinancial conflicts of interest in any article reviewed. Disclosure policies and the very definition of conflict of interest varied considerably among journals. Although most journals had some policy in this area, a substantial proportion did not publish disclosure statements consistently, with deficiencies particularly among editorials and commentaries.

To identify global research trends in the use of nerve conduits for peripheral nerve injury repair. Numerous basic and clinical studies on nerve conduits for peripheral nerve injury repair were performed between 2002-2011. We performed a bibliometric analysis of the institutions, authors, and hot topics in the field, from the Web of Science, using the key words peripheral nerve and conduit or tube. peer-reviewed published articles on nerve conduits for peripheral nerve injury repair, indexed in the Web of Science; original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items. articles requiring manual searching or telephone access; documents not published in the public domain; and several corrected papers. (a) Annual publication output; (b) publication type; (c) publication by research field; (d) publication by journal; (e) publication by funding agency; (f) publication by author; (g) publication by country and institution; (h) publications by institution in China; (i) most-cited papers. A total of 793 publications on the use of nerve conduits for peripheral nerve injury repair were retrieved from the Web of Science between 2002-2011. The number of publications gradually increased over the 10-year study period. Articles constituted the main type of publication. The most prolific journals were Biomaterials, Microsurgery, and Journal of Biomedical Materials Research Part A. The National Natural Science Foundation of China supported 27 papers, more than any other funding agency. Of the 793 publications, almost half came from American and Chinese authors and institutions. Nerve conduits have been studied extensively for peripheral nerve regeneration; however, many problems remain in this field, which are difficult for researchers to reach a consensus.

To analyze the current research status of evidence-based nursing of burn in the mainland of China, in order to provide basis for the improvement of scientificity of burn nursing practice. Chinese scientific articles on evidence-based nursing of burn in the mainland of China published from January 1997 to December 2015 were retrieved from Chinese Biology Medicine disc, Chinese Journals Full-text Database, Wanfang Database, and VIP Database. From the results retrieved, date with regard to publication year, region of affiliation of the first author, journal distribution, literature type, literature quality assessment, topic of evidence-based research, fund program support, implementation of evidence-based practice steps, and language and quantity of reference. Data were processed with Microsoft Excel software. A total of 50 articles conforming to the criteria were retrieved. (1) Articles about evidence-based nursing of burn arose in 2004. Compared with that in the previous year, there was no obvious increase in the number of relevant articles in each year from 2004 to 2011. The number of literature in 2012 was obviously increased than that in each year from 2004 to 2011, while the number of literature in each year from 2012 to 2015 was not obviously increased compared with that in the previous year. (2) The regions of affiliation of the first author were distributed in 13 provinces, 3 minority autonomous regions, and 3 municipalities, with the largest distribution in East China, and Northwest China and Southwest China in the follow. (3) The articles were published in 32 domestic journals, with 9 (28.12%) nursing journals, 5 (15.62%) burn medical related journals, and 18 (56.25%) other journals. Twenty (40%) articles were published in Source Journal for Chinese Scientific and Technical Papers. (4) Regarding the literature type, 31 (62%) articles dealt with clinical experiences, 17 (34%) articles dealt with scientific research, and 2 (4%) articles dealt with case report. (5) There were 21 quantitative study articles and 29 narrative study articles, all with low quality. (6) The topics of evidence-based research in these articles were mainly burn rehabilitation, burn nursing technology, pediatric burn, inhalation injury and airway management, and complications of burn injury. Only one study was supported by fund program. (7) Only one article described complete evidence-based practice steps. (8) The literature cited 57 English articles as references, with an average of 1.14, and 316 Chinese articles, with an average of 6.32. The concept of evidence-based nursing of burn has been initially formed in the mainland of China. The number of relevant articles is on the rise, but the quality needs to be further improved. There is an urgent need to improve nurses' understanding of evidence-based nursing and their command of the method of evidence-based practice through on-job training, so as to improve the scientificity and effectiveness of burn nursing.

This article describes the results of three studies designed to understand better the journal operations, publishing practices, and impact of school psychology journals in recent years. The first study presents the results of a survey focusing on journal operations and peer-review practices that was completed by 61 journal editors of school psychology and aligned journals. The second study presents the results of review and classification of all articles appearing in one volume year for nine school psychology journals (i.e., The California School Psychologist, Canadian Journal of School Psychology, Journal of Applied School Psychology, Journal of School Psychology, Psychology in the Schools, School Psychology Forum, School Psychology International, School Psychology Quarterly, and School Psychology Review). The third study employed multilevel modeling to investigate differences in the longitudinal trends of impact factor data for five school psychology journals listed in the Web of Science (i.e., Journal of School Psychology, Psychology in the Schools, School Psychology International, School Psychology Quarterly, and School Psychology Review). The article addresses implications for authors, editors, and journal editorial teams as well as the status and impact of school psychology journals.

Retracted Publications Within Radiology Journals.
Rosenkrantz, Andrew B
2016-02-01
The purpose of this study was to characterize trends related to retracted publications within radiology journals. PubMed was queried to identify all articles with the publication type "retracted publication" or "notification of retraction." Articles published within radiology journals were identified using Journal Citation Reports' journal categories. Available versions of original articles and publication notices were accessed from journal websites. Citations to retracted publications were identified using Web of Science. Overall trends were assessed. Forty-eight retracted original research articles were identified within radiology journals since 1983, which included 1.1% of all PubMed "retracted publication" entries. Distinct PubMed entries were available for the retracted publication and retraction notification in 39 of 48 articles. The original PDF was available for 37 articles, although the articles were not watermarked as retracted in 23 cases. In six cases with a watermarked PDF, further searches identified nonwatermarked versions. Original HTML versions were available for 13 articles but 11 were not watermarked. The mean (± SD) delay between publication and retraction was 2.7 ± 2.8 years (range, 0-16 years). The mean number of citations to retracted articles was 10.9 ± 17.1 (range, 0-94 citations). Reasons for retraction included problematic or incorrect methods or results (although it typically was unclear whether these represented honest errors or misconduct) in 33.3% of cases, complete or partial duplicate publication in 33.3% of cases, plagiarism in 14.6% of cases, a permission issue in 8.3% of cases, the publisher's error in 6.3% of cases, and no identified reason in 6.3% of cases. One or no retractions occurred annually from 1986 to 2001, although two or more retractions occurred annually in nine of the 12 years from 2002 through 2013. Retraction represents an uncommon, yet potentially increasing, issue within radiology journals that publishers have inconsistently and insufficiently addressed. Greater awareness and training in proper biomedical research conduct, as well as establishment and enforcement of standardized publishers' policies, are warranted.

To investigate the distribution, design characteristics, and dissemination of clinical trials by funding organisation and medical specialty. Cross sectional descriptive analysis. Trial protocol information from clinicaltrials.gov, metadata of journal articles in which trial results were published (PubMed), and quality metrics of associated journals from SCImago Journal and Country Rank database. All 45 620 clinical trials evaluating small molecule therapeutics, biological drugs, adjuvants, and vaccines, completed after January 2006 and before July 2015, including randomised controlled trials and non-randomised studies across all clinical phases. Industry was more likely than non-profit funders to fund large international randomised controlled trials, although methodological differences have been decreasing with time. Among 27 835 completed efficacy trials (phase II-IV), 15 084 (54.2%) had disclosed their findings publicly. Industry was more likely than non-profit trial funders to disseminate trial results (59.3% (10 444/17 627) v 45.3% (4555/10 066)), and large drug companies had higher disclosure rates than small ones (66.7% (7681/11 508) v 45.2% (2763/6119)). Trials funded by the National Institutes of Health (NIH) were disseminated more often than those of other non-profit institutions (60.0% (1451/2417) v 40.6% (3104/7649)). Results of studies funded by large drug companies and NIH were more likely to appear on clinicaltrials.gov than were those from non-profit funders, which were published mainly as journal articles. Trials reporting the use of randomisation were more likely than non-randomised studies to be published in a journal article (6895/19 711 (34.9%) v 1408/7748 (18.2%)), and journal publication rates varied across disease areas, ranging from 42% for autoimmune diseases to 20% for oncology. Trial design and dissemination of results vary substantially depending on the type and size of funding institution as well as the disease area under study.

To investigate the amount, type and accuracy of citations use in support of product related claims from advertisements of wound care products. Although articles submitted to most medical journals are subjected to peer review, such scrutiny is often not required for the content of advertisements. A contents survey of advertisements from two wound care journals (Journal of Wound Care and Ostomy Wound Management) from 2002-2003 and the British Medical Journal, 2002-2003. Data collected from advertisements included identification of product related claims made and any corresponding citations. Where journal articles were cited to support claims, the articles were obtained. Where data on file were cited, this material was requested. In each case the accuracy of claims in relation to the content of the supporting citation was assessed. The use of citations to support product related claims was infrequent in advertisements from wound care journals, where 35% of advertisements containing a product related claim also contained at least one citation, compared with 63% of advertisements from the British Medical Journal. Of citations that were supplied, journal articles were less common in the wound journals (40% vs. 73% in the British Medical Journal) and data on file more common (38% vs. 6% in the British Medical Journal). Where journal articles were obtained, 56% of claims in the wound care journals advertisements were not supported by the cited article, compared with 12% of claims in the British Medical Journal. The wound journals advertised predominantly medical devices. The use and accuracy of referencing in advertisements from wound care journals was poor. Nurses have increasing responsibilities for the prescribing of both drugs and devices, which must be accompanied by the ability to interpret marketing materials and research evidence critically. Nurse educators must ensure that nurse education generally and nurse prescriber training particularly, builds skills of information retrieval and critical appraisal.

Every article on stimulus equivalence or derived stimulus relations published in the Journal of Applied Behavior Analysis was evaluated in terms of characteristics that are relevant to the development of applied technologies: the type of participants, settings, procedure (automated vs. tabletop), stimuli, and stimulus sensory modality; types of relations targeted and emergent skills demonstrated by participants; and presence versus absence of evaluation of generalization and maintenance. In most respects, published reports suggested the possibility of applied technologies but left the difficult work of technology development to future investigations, suggestions for which are provided.
[Errors in Peruvian medical journals references].
Huamaní, Charles; Pacheco-Romero, José
2009-01-01
References are fundamental in our studies; an adequate selection is asimportant as an adequate description. To determine the number of errors in a sample of references found in Peruvian medical journals. We reviewed 515 scientific papers references selected by systematic randomized sampling and corroborated reference information with the original document or its citation in Pubmed, LILACS or SciELO-Peru. We found errors in 47,6% (245) of the references, identifying 372 types of errors; the most frequent were errors in presentation style (120), authorship (100) and title (100), mainly due to spelling mistakes (91). References error percentage was high, varied and multiple. We suggest systematic revision of references in the editorial process as well as to extend the discussion on this theme. references, periodicals, research, bibliometrics.

The purpose of this study was to conduct a bibliographic analysis and assessment of the literature published in the Journal of Clinical Chiropractic Pediatrics (JCCP). The content of the 13 existing issues of the JCCP (1996-2007) were assessed. Articles were categorized by type, and information concerning author affiliation, academic/professional background and gender were tabulated. A second-level analysis applied specific criteria checklists to applicable articles to determine the quality rating of each paper. There were 72 articles included in the analysis, of which 46% were case reports, 17% editorials, 13% case series, 10% narrative literature reviews, 10% commentaries, 4% "other," and 1% cross-sectional studies. Seventy-five percent of the authors were "private practitioners." A certification in chiropractic pediatrics was held by 43% of the authors; 65% of the authors were females, and 83% of the articles had a single author. After applying the checklist to specific articles, 13 articles (18%) scored 40% or better (range of 40%-67%), whereas 59 articles (82%) scored less than 40%. The findings of this analysis suggest there is room for improvement in article type and publication quality of papers in the JCCP.
The STROBE extensions: protocol for a qualitative assessment of content and a survey of endorsement.
Sharp, Melissa K; Utrobičić, Ana; Gómez, Guadalupe; Cobo, Erik; Wager, Elizabeth; Hren, Darko
2017-10-22
The STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) Statement was developed in response to inadequate reporting of observational studies. In recent years, several extensions to STROBE have been created to provide more nuanced field-specific guidance for authors. The content and the prevalence of extension endorsement have not yet been assessed. Accordingly, there are two aims: (1) to classify changes made in the extensions to identify strengths and weaknesses of the original STROBE checklist and (2) to determine the prevalence and typology of endorsement by journals in fields related to extensions. Two independent researchers will assess additions in each extension. Additions will be coded as 'field specific' (FS) or 'not field specific' (NFS). FS is defined as particularly relevant information for a single field and guidance provided generally cannot be extrapolated beyond that field. NFS is defined as information that reflects epidemiological or methodological tenets and can be generalised to most, if not all, types of observational research studies. Intraclass correlation will be calculated to measure reviewers' concordance. On disagreement, consensus will be sought. Individual additions will be grouped by STROBE checklist items to identify the frequency and distribution of changes.Journals in fields related to extensions will be identified through National Library of Medicine PubMed Broad Subject Terms, screened for eligibility and further distilled via Ovid MEDLINE® search strategies for observational studies. Text describing endorsement will be extracted from each journal's website. A classification scheme will be created for endorsement types and the prevalence of endorsement will be estimated. Analyses will use NVivo V.11 and SAS University Edition. This study does not require ethical approval as it does not involve human participants. This study has been preregistered on Open Science Framework. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

Journal Impact Factor: Do the Numerator and Denominator Need Correction?
Liu, Xue-Li; Gai, Shuang-Shuang; Zhou, Jing
2016-01-01
To correct the incongruence of document types between the numerator and denominator in the traditional impact factor (IF), we make a corresponding adjustment to its formula and present five corrective IFs: IFTotal/Total, IFTotal/AREL, IFAR/AR, IFAREL/AR, and IFAREL/AREL. Based on a survey of researchers in the fields of ophthalmology and mathematics, we obtained the real impact ranking of sample journals in the minds of peer experts. The correlations between various IFs and questionnaire score were analyzed to verify their journal evaluation effects. The results show that it is scientific and reasonable to use five corrective IFs for journal evaluation for both ophthalmology and mathematics. For ophthalmology, the journal evaluation effects of the five corrective IFs are superior than those of traditional IF: the corrective effect of IFAR/AR is the best, IFAREL/AR is better than IFTotal/Total, followed by IFTotal/AREL, and IFAREL/AREL. For mathematics, the journal evaluation effect of traditional IF is superior than those of the five corrective IFs: the corrective effect of IFTotal/Total is best, IFAREL/AR is better than IFTotal/AREL and IFAREL/AREL, and the corrective effect of IFAR/AR is the worst. In conclusion, not all disciplinary journal IF need correction. The results in the current paper show that to correct the IF of ophthalmologic journals may be valuable, but it seems to be meaningless for mathematic journals. PMID:26977697

Black Studies scholars have shown interest in the core journal concept. Indeed, the idea of core journals for the study of the Black experience has changed several times since 1940. While Black Studies scholars are citing Black Studies journals with frequency, they also cite traditional disciplinary journals a great deal of the time. However,…
Open access to journal articles in oncology: current situation and citation impact.
Hua, F; Sun, H; Walsh, T; Glenny, A-M; Worthington, H
2017-10-01
Recent years have seen numerous efforts and resources devoted to the development of open access (OA), but the current OA situation of the oncology literature remains unknown. We conducted this cross-sectional study to determine the current share and provision methods of OA in the field of oncology, identify predictors of OA status (OA versus non-OA), and study the association between OA and citation counts. PubMed was searched for oncology-related, peer-reviewed journal articles published in December 2014. Google, Google Scholar, PubMed, ResearchGate, OpenDOAR and OAIster were manually checked to assess the OA status of each included article. Citation data were extracted from Web of Science, Scopus and Google Scholar. Descriptive statistics were used to summarize the OA proportion (primary outcome) and OA provision methods. Multivariable logistic regression and multilevel generalized linear model analyses were performed to study predictors of OA status and the association between OA and citation counts, respectively. In a random sample of 1000 articles, 912 were deemed eligible and therefore included. Of these, the full-texts of 530 articles (58.1%; 95% CI: 54.9-61.3) were freely available online: 314 (34.4%) were available from publishers ('Gold road' to OA), 424 (46.5%) were available via self-archiving ('Green road' to OA). According to multivariable regression analyses, impact factor, publisher type, language, research type, number of authors, continent of origin, and country income were significant predictors of articles' OA status; OA articles received a citation rate 1.24 times the incidence rate for non-OA articles (95% CI: 1.05-1.47; P = 0.012). Based on our sample, in the field of oncology, 42% of recent journal articles are behind the pay-wall (non-OA) 1 year after publication; the 'Green road' of providing OA is more common than the 'Gold road'; OA is associated with higher citation counts. © The Author 2017.

A modified forward iteration approach for the coupled solution of foil bearings is presented. The method is used to predict the steady state theoretical performance of a journal type gas bearing constructed from an inextensible shell supported by an elastic foundation. Bending effects are treated as negligible. Finite element methods are used to predict both the foil deflections and the pressure distribution in the gas film.

Objectives The aim of this study is to compare the quantity and quality of scientific publications in transplantation fields that were written by researchers from Mainland China, Japan, South Korea and Taiwan in the East Asia region. Settings East Asia. Participants and outcome measures Articles except editorials, conference abstracts, letters, news and corrections published in 25 transplantation journals from 2006 to 2015 were screened with the Web of Science database. The number of total and annual articles, article types (study design and transplantation site), impact factor, citations and articles in the high-impact journals was determined to assess the quantity and quality of transplantation research from East Asia. The correlation of socioeconomic factors and annual publications was also analysed. Results From 2006 to 2015, there were 47 141 articles published in transplantation journals, of which researchers from Japan published 3694 articles, followed by Mainland China, South Korea and Taiwan with 2778, 1643 and 951 articles, respectively. Similar trends were observed in accumulated impact factor, accumulated citations, articles in the high-impact journals and articles on transplantation site. Publications from Japan had the highest average impact factor and citation, while those from Mainland China had the lowest. Additionally, in terms of study design, authors from Mainland China contributed to most clinical trials and randomised controlled trials, but authors from Japan contributed to most case reports. The annual numbers of articles from Mainland China and South Korea increased linearly (p<0.05), but those from Japan and Taiwan remained stable for the period studied. The annual numbers of articles from Mainland China and South Korea were positively correlated with gross domestic product (p<0.05). Conclusions Transplantation research productivity in East Asia is highly skewed, with gross domestic product having a significant positive correlation. Mainland China still lags far behind Japan in most bibliometric indicators; thus, there is vast room for improvement. PMID:27489154

To examine variables that affect publication of ACVO meeting abstracts in peer-reviewed journals and compare results to ECVO publication rate (PR). Published papers were identified via online searches for abstracts from 2008 to 2012 ACVO/ECVO meetings. Variables analyzed (via Pearson's chi-Squared test) included the following: oral presentation/poster, type of abstract (clinical/basic science/case report), species, ocular tissue, nationality, funding, first/last/any author a diplomate, resident as first author, and author affiliation (private practice/university). One hundred and eighty-six of 577 ACVO abstracts were published within 608 ± 479 days, with 103 published in Veterinary Ophthalmology. Significant factors included the following: nationality of first/last authors (P = .005); English as first language (P < .001); presentation type (P < .001, oral 40% PR, poster 22% PR); type of study (P = .037, clinical study 35% PR, basic science 30% PR, case report 16% PR); resident as first author (P < .001); diplomate as any author except first/last (P < .001); first author affiliation (P = .001, university 37% PR, practice 21% PR); last author affiliation (P = .003, university 36% PR, practice 22% PR); and species (P < .001, horses 53% PR, multiple species 50% PR, cats 35% PR, food animals 31% PR, exotics/wildlife 31% PR, dogs 27% PR, laboratory animals/in vitro 24%). Nonsignificant factors were as follows: diplomate as first/last author, funding, and ocular tissue. Presentation type, resident as first author, university affiliation of first author, and species had the greatest effect on publication probability. For the same period, ECVO PR was 87 of 299, which was not significantly different from ACVO PR (P = .342). At 32%, ACVO PR for the study years is similar to ECVO PR of 29%. © 2018 American College of Veterinary Ophthalmologists.

The Internet represents a different type of technology for publishers of scientific, technical, and medical journals. It is not a technology that sustains current markets and creates new efficiencies but is, rather, a disruptive technology that could radically alter market forces, profit expectations, and business models. This paper is a translation and amplification of the research done in this area, applied to a large-circulation new science journal, Pediatrics. The findings suggest that the journal of the future will be electronic, have a less volatile cost structure, be supported more by services than by content, be less able to rely on subscription revenues, and abandon certain elements of current value networks. It also provides a possible framework for other publishers to use to evaluate their own journals relative to this disruptive technology. PMID:10833160
[The 100 Most Often Articles on Glaucoma Research: a Bibliometric Analysis].

Background Bibliometric science employs statistical and quantitative analyses to analyse the scholarly impact and characteristics of publications within a research field. The present study was initiated to analyse and quantify the 100 most often cited papers in glaucoma research. Materials and Methods The databases of the Institute for Scientific Information were utilised for the identification of articles published from 1900 to December 2016. All glaucoma articles were identified that had been published in 109 relevant journals and which had been cited at least 200 times. The top 100 articles were selected for further analysis of authorship, source journal, number of citations, citation rate, geographic origin, article type, and level of evidence. Results The publication dates of the 100 most often cited articles ranged from 1966 to 2011, with the greatest number of articles published in the 1990s. Citations per article ranged from 258 to 1908. All articles were published in 18 of the 109 journals. The leading countries of origin were the U. S. A., followed by the U. K. The study focussed on two main clinical articles (diagnostics; epidemiology) and basic research articles. The number of citations per article was greatest for articles published in the 2000s. Most articles provided level III evidence, followed by levels I and II. Conclusion The majority of the most cited articles were published in three of the top-ranked journals. Most clinical articles dealt with epidemiology and diagnostics. Individuals who authored multiple articles in the list often focussed on one of these two areas. Most studies were conducted in the U. S. A. and presented level III clinical outcomes. This indicates that even studies with small case series or cohort studies can attract attention. Georg Thieme Verlag KG Stuttgart · New York.

Despite the fact that research fraud and misconduct are under scrutiny in the field of orthopaedic research, little systematic work has been done to uncover and characterise the underlying reasons for academic retractions in this field. The purpose of this study was to determine the rate of retractions and identify the reasons for retracted publications in the orthopaedic literature. Two reviewers independently searched MEDLINE, EMBASE, and the Cochrane Library (1995 to current) using MeSH keyword headings and the 'retracted' filter. We also searched an independent website that reports and archives retracted scientific publications (www.retractionwatch.com). Two reviewers independently extracted data including reason for retraction, study type, journal impact factor, and country of origin. One hundred and ten retracted studies were included for data extraction. The retracted studies were published in journals with impact factors ranging from 0.000 (discontinued journals) to 13.262. In the 20-year search window, only 25 papers were retracted in the first ten years, with the remaining 85 papers retracted in the most recent decade. The most common reasons for retraction were fraudulent data (29), plagiarism (25) and duplicate publication (20). Retracted articles have been cited up to 165 times (median 6; interquartile range 2 to 19). The rate of retractions in the orthopaedic literature is increasing, with the majority of retractions attributed to academic misconduct and fraud. Orthopaedic retractions originate from numerous journals and countries, indicating that misconduct issues are widespread. The results of this study highlight the need to address academic integrity when training the next generation of orthopaedic investigators.Cite this article: J. Yan, A. MacDonald, L-P. Baisi, N.

Half-century of Dental Public Health research: bibliometric analysis of world scientific trends.
Celeste, Roger Keller; Broadbent, Jonathan M; Moyses, Samuel Jorge
2016-12-01
To describe the characteristics of Dental Public Health (DPH) scientific publications within core DPH journals over time and to compare DPH journals with DPH content from other journal types. The Scopus database was used to identify DPH-relevant articles published from 1965 to 2014 in three core DPH journals (DPHJs) and from 2005 to 2014 in Dental Journals (DJs), Public Health (PHJs) and General Journals (GJs). To identify DPH-relevant articles, a search strategy with words about oral health and public health was applied to each group of journals. Research themes were created by grouping similar keywords to report changes in the focus of articles over time. The most productive journals, countries, institutions and authors were also estimated for each set of journals. In 2005-2014, 60 297 articles were identified, of which 2.7% in DPHJs, 10.4% from PHJs, 38.2% from GJs and 48.7% from DJs. DPH-relevant articles published in the core DPHJs, DJs and PHJs tended to share a strong emphasis on dental caries, healthcare/services research on children and adolescents. Over time, the focus in the DPHJs has increased towards health behaviour/promotion/education, quality of life and socioeconomic factors. In the last decade, those themes were more frequent in DPH journals than in the other groups. DPH research published in DPHJs had some unique features and greater focus on the themes of quality of life, socioeconomic factors and health behaviour/education/promotion than other groups of journals. © 2016 John Wiley & Sons A/S.

This article, which began as an effort to gauge trends in and contributions to the broad field of "entrepreneur/entrepreneurship," reviews 5,476 academic articles on entrepreneurship that were published in 522 Social Sciences Citation Index and Science Citation Index journals from 1996 to June 2012. This survey identifies keywords and conducts a review to search for and identify related articles in the Institute for Scientific Information Web of Science database. We then present our findings, including the number of publications by year, categorization of article types, main academic journals, authors, and most-cited articles. The citation counts for authors, journals, and articles are also analyzed. This study indicates that the number of articles related to the keyword entrepreneur increased from 1996 to the end of 2011, which is a sign of an upward trend in the influence of entrepreneurs. Entrepreneur research fascinated numerous scholars during the study period covering 16.5 years. In particular, researchers from the USA, England, Canada, Germany, and the Netherlands have made the most contributions to this field. This literature review provides evidence that the concept of entrepreneur attracted academic researchers, resulting in significant contributions to the field of entrepreneur research.
Enhancing Scientific Communication Through an Undergraduate Biology and Journalism Partnership.
Schwingel, Johanna M
2018-01-01
Scientific terminology presents an obstacle to effective communication with nonscientific audiences. To overcome this obstacle, biology majors in a general microbiology elective completed a project involving two different audiences: a scientific audience of their peers and a general, nonscientific audience. First, students presented an overview of a primary research paper and the significance of its findings to a general, nonscientific audience in an elevator-type talk. This was followed by a peer interview with a student in a journalism course, in which the biology students needed to comprehend the article to effectively communicate it to the journalism students, and the journalism students needed to ask questions about an unfamiliar, technical topic. Next, the biology students wrote a summary of their article for a scientific audience. Finally, the students presented a figure from the article to their peers in a scientific, Bio-Minute format. The biology-journalism partnership allowed biology students to develop their ability to communicate scientific information and journalism students their ability to ask appropriate questions and establish a base of knowledge from which to write.

To explore academic significance and guiding function played by subspecialty groups of the Society of Pediatrics, Chinese Medical Association on Chinese pediatric clinical practice through a statistical analysis of the articles published by the subspecialty groups. Bibliometric methods were used to analyze the number of articles, article types, total citations, highly cited articles and the distribution of citing journals. Totally 7 156 articles were published in Chinese Journal of Pediatrics from 1993 (31) to 2012 (51), of which 187 by subspecialty groups of pediatrics (2.6%), with a total citations of 11 985. Among them, 137 articles were cited with a citation rate of 73.3% and average citations for each article was 64.1. Articles classified as clinical guidelines had been totally cited for 10 900 times with average citations of 123.86 per article. The article on Neonatal hypoxic ischemic encephalopathy diagnosis and clinical index was cited 1 791 times ranked in highly cited literatures. All the top three cited literature periodicals were core journals of pediatrics, and 10 periodicals among the top 20 were in pediatrics and the rest in other medical fields. The number of the articles published by the subspecialty groups of pediatrics was increasing year by year though the portion it in the total number of the articles in the journal was not large. However, the citation frequency of the articles by the subspecialty groups of pediatrics was high, making an obvious contribution to the total citations of Chinese Journal of Pediatrics. The total citation rate of clinical guideline articles and their average rate was higher than those of other articles published in this journal, which meant that this type of articles provided academic references with guiding significance for clinical practice of pediatrics and for other medical fields as well.
Philosophical Provocation: The Lifeblood of Clinical Ethics.
McCullough, Laurence B
2017-02-01
The daily work of the clinical ethics teacher and clinical ethics consultant falls into the routine of classifying clinical cases by ethical type and proposing ethically justified alternatives for the professionally responsible management of a specific type of case. Settling too far into this routine creates the risk of philosophical inertia, which is not good either for the clinical ethicist or for the field of clinical ethics. The antidote to this philosophical inertia and resultant blinkered vision of clinical ethics is sustained, willing exposure to philosophical provocation. The papers in this clinical ethics issue of the Journal of Medicine and Philosophy provide just such philosophical provocation related to core topics in clinical ethics: the distinction between clinical practice and clinical research; telemedicine, or medicine at a distance; illness narratives; the concept of the placebo effect; and sex reassignment. © The Author 2017.

Medical research outsourcing provides a financial benefit to those conducting research and financial incentives to the developing countries hosting the research. Little is known about how frequently outsourcing occurs or the type of research that is outsourced. To document changes in medical research outsourcing over a 10-year period, we conducted a cross-sectional comparison of 3 medical journals: Lancet, The New England Journal of Medicine, and JAMA: The Journal of the American Medical Association in the last 6 months of 1995 and 2005. The main outcome measure was the 10-year change in proportion of studies including patients from low-income countries. We reviewed 598 articles. During the 10-year period, the proportion of first authors from low-income countries increased from 3% to 6% (P = 0.21), whereas studies with participants from low-income countries increased from 8% to 22% (P = < 0.001). In 2005, compared with studies conducted exclusively in high-income countries, those including participants from low-income countries were more likely to be randomized trials (55% vs 35%, P = 0.004), to study medications (65% vs 34%, P < 0.001), to be funded by pharmaceutical companies (33% vs 21%, P = 0.05), and to involve pediatric populations (29% vs 8%, P < 0.001). Outsourcing of medical research seems to be increasing. Additional studies are required to know if subjects from low-income countries are being adequately protected.

Malaria research can play a vital role in addressing the malaria burden in Malawi. An organized approach in addressing malaria in Malawi started in 1984 by the establishment of the first National Malaria Control Programme and research was recognized to be significant. This study aimed to assess the type and amount of malaria research conducted in Malawi from 1984 to 2016 and its related source of funding. A systematic literature search was conducted in the Medline/PubMed database for Malawian publications and approved malaria studies from two Ethical Committees were examined. Bibliometric analysis was utilized to capture the affiliations of first and senior/last authors, funding acknowledgements, while titles, abstracts and accessed full text were examined for research type. A total of 483 publications and 165 approved studies were analysed. Clinical and basic research in the fields of malaria in pregnancy 105 (21.5%), severe malaria 97 (20.1%) and vector and/or agent dynamics 69 (14.3%) dominated in the publications while morbidity 33 (20%), severe malaria 28 (17%) and Health Policy and Systems Research 24 (14.5%) dominated in the approved studies. In the publications, 146 (30%) first authors and 100 (21%) senior authors, and 88 (53.3%) principal investigators in approved studies were affiliated to Malawian-based institutions. Most researchers were affiliated to the Malawi-Liverpool Wellcome Trust, College of Medicine, Blantyre Malaria Project, Ministry of Health, and Malaria Alert Centre. The major malaria research funders were the National Institute for Health/USA, Wellcome Trust and the US Agency for International Development. Only three (2.5%) out of 118 journals publishing research on malaria in Malawi were from Africa and the Malaria Journal, with 76 (15.7%) publications, published most of the research from Malawi, followed by the American Journal of Tropical Medicine and Hygiene with 57 (11.8%) in comparison to only 13 (2.7%) published in the local Malawi Medical Journal. Clinical and basic research, which is mostly funded externally, in the fields of malaria in pregnancy, severe malaria and vector and/or agent dynamics dominated, while health policy and system research was least supported. The quantity may reflect scientific research activity but the initial primary impact is contribution to policy development.

In 1982, the Annals of Virology published a paper showing how Liberia has a highly endemic potential of Ebola warning health authorities of the risk for potential outbreaks; this journal is only available by subscription. Limiting the accessibility of such knowledge may have reduced information propagation toward public health actors who were indeed surprised by and unprepared for the 2014 epidemic. Open access (OA) publication can allow for increased access to global health research (GHR). Our study aims to assess the use, cost and impact of OA diffusion in the context of GHR. A total of 3366 research articles indexed under the Medical Heading Subject Heading "Global Health" published between 2010 and 2014 were retrieved using PubMed to (1) quantify the uptake of various types of OA, (2) estimate the article processing charges (APCs) of OA, and (3) analyse the relationship between different types of OA, their scholarly impact and gross national income per capita of citing countries. Most GHR publications are not available directly on the journal's website (69%). Further, 60.8% of researchers do not self-archive their work even when it is free and in keeping with journal policy. The total amount paid for APCs was estimated at US$1.7 million for 627 papers, with authors paying on average US$2732 per publication; 94% of APCs were paid to journals owned by the ten most prominent publication houses from high-income countries. Researchers from low- and middle-income countries are generally citing less expensive types of OA, while researchers in high-income countries are citing the most expensive OA. Although OA may help in building global research capacity in GHR, the majority of publications remain subscription only. It is logical and cost-efficient for institutions and researchers to promote OA by self-archiving publications of restricted access, as it not only allows research to be cited by a broader audience, it also augments citation rates. Although OA does not ensure full knowledge transfer from research to practice, limiting public access can negatively impact implementation and outcomes of health policy and reduce public understanding of health issues.
A study on the development of public campaign messages for organ donation promotion in Korea.
Sun, Hye-Jin
2015-12-01
This study aims to find an effective method of expressing a message in public service ads by investigating whether or not a message framing type affects the outcome. Specifically, the study looks into the effects of messaging on organ donation by identifying how the type of message framing (positive vs. negative) and appeal type (rational vs. emotional) affect the attitude and behavioural intention of the consumer. The individual characteristics of each subject such as altruistic mind, level of self-monitoring and issue involvement were selected as intermediate variables that may affect the impact of a message. The study therefore tries to establish a proposition that can be used to generate an effective promotional message on organ donation in a systematic way. © The Author (2014).

Persian Medicine in the World of Research; Review of Articles on Iranian Traditional Medicine.
Moeini, Reihaneh; Gorji, Narjes
2016-05-01
Due to negligence, Persian (Iranian) traditional medicine has had a weak presence in the world of research for a long time. However, in recent years, a variety of activates by research and faculty centers have created awareness and a platform to introduce and promote Persian medicine to the world. The aim of this study is to present and analyze scientific achievements of Persian medicine in the world of research. Articles were collected from PubMed database using keywords such as "Persian medicine", "Persian traditional medicine", "Iranian medicine", and "Iranian traditional medicine". All data were classified based on the type of research (review, intervention, case reports, etc.), the field of study (neurology, cardiovascular, metabolic, historical studies, etc.), publication year, and journal type. A total of 501 articles were identified until the end of 2015, comprising of 222 reviews and 219 interventional (108 animal, 57 clinical and 54 cellular). Most studies were on neurology (20.1%), gastroenterology (14.5%), and cardiovascular diseases (10.4%). The publications in 2015 and 2014 had the highest hit rate with 139 and 132 articles, respectively, with 1:2 publication ratio between foreign and Iranian journals. The most published articles, both foreign and Iranian, were in "Evidence-Based Complementary and Alternative Medicine" and "Iranian Red Crescent Medicine" journals. The contribution of foreign authors was 5%. The primary focus of the articles was on "Basic concepts of Persian medicine", "Healthy lifestyle according to Persian medicine", and "Historical aspects", by 3.1%, 2.9%, and 6.7%, respectively. During the last 2 years, the number of articles published in Persian (Iranian) medicine, particularly clinical studies had significant growth in comparison with the years before. The tendency of foreign researchers to use the keywords "Iranian" or "Persian" medicine is notable. This research was only based on the designated keyword and other keywords were omitted. It is recommended that additional keywords be used in a broader investigation.

Bibliometrics of systematic reviews: analysis of citation rates and journal impact factors
2013-01-01
Background Systematic reviews are important for informing clinical practice and health policy. The aim of this study was to examine the bibliometrics of systematic reviews and to determine the amount of variance in citations predicted by the journal impact factor (JIF) alone and combined with several other characteristics. Methods We conducted a bibliometric analysis of 1,261 systematic reviews published in 2008 and the citations to them in the Scopus database from 2008 to June 2012. Potential predictors of the citation impact of the reviews were examined using descriptive, univariate and multiple regression analysis. Results The mean number of citations per review over four years was 26.5 (SD ±29.9) or 6.6 citations per review per year. The mean JIF of the journals in which the reviews were published was 4.3 (SD ±4.2). We found that 17% of the reviews accounted for 50% of the total citations and 1.6% of the reviews were not cited. The number of authors was correlated with the number of citations (r = 0.215, P < 0.001). Higher numbers of citations were associated with the following characteristics: first author from the United States (36.5 citations), an ICD-10 chapter heading of Neoplasms (31.8 citations), type of intervention classified as Investigation, Diagnostics or Screening (34.7 citations) and having an international collaboration (32.1 citations). The JIF alone explained more than half of the variation in citations (R2 = 0.59) in univariate analysis. Adjusting for both JIF and type of intervention increased the R2 value to 0.81. Fourteen percent of reviews published in the top quartile of JIFs (≥ 5.16) received citations in the bottom quartile (eight or fewer), whereas 9% of reviews published in the lowest JIF quartile (≤ 2.06) received citations in the top quartile (34 or more). Six percent of reviews in journals with no JIF were also in the first quartile of citations. Conclusions The JIF predicted over half of the variation in citations to the systematic reviews. However, the distribution of citations was markedly skewed. Some reviews in journals with low JIFs were well-cited and others in higher JIF journals received relatively few citations; hence the JIF did not accurately represent the number of citations to individual systematic reviews.

Microsurgery: the top 50 classic papers in plastic surgery: a citation analysis.
Joyce, Cormac Weekes; Carroll, Sean Michael
2014-03-01
The number of citations that a published article has received reflects the importance of the paper in the particular area of practice. In microsurgery, thus far, which journal articles are cited most frequently is unknown. The purpose of this study was to identify and analyze the characteristics of the top 50 papers in the field of microsurgery in the plastic surgery literature. The 50 most cited papers published in high impact plastic surgery and microsurgery journals were identified. The articles were ranked in the order of the number of citations received. These 50 classic papers were analyzed for article type, journal distribution, and geographic and institutional origin. Six international journals contributed to the top 50 papers in microsurgery. The most cited paper reported on the early use of the vascularized bone graft and was cited 116 times. The top 50 papers originated from just 10 countries with the United States producing the most. The Preston and Northcote Community Hospital, Melbourne published 5 papers and this was the most productive institution in the top 50. These papers represent many important milestones in the relatively short history of microsurgery. Furthermore, our citation analysis provides useful information to budding authors as to what makes a paper attain a "classic" status.
Thinking style changes among deaf, hard-of-hearing, and hearing students.
Cheng, Sanyin; Zhang, Li-fang
2015-01-01
This study explores how university students' thinking styles changed over a single academic year by twice administering the Thinking Styles Inventory-Revised II to 256 deaf or hard-of-hearing (DHH) students and 286 hearing students from art and design academic disciplines in China. Results showed that after having studied at the university for one academic year, hearing students showed increased use of Type I thinking styles (more creativity generated, less structured, and more complex) and less use of Type II thinking styles (more norm favoring, more structured, and more simplistic), whereas DHH students demonstrated increased use of both Type I and Type II thinking styles. Moreover, students' changes in thinking styles differed across university class levels. The contributions, limitations, and implications of the present research are discussed. © The Author 2014.

Purpose The purpose of this systematic review was to review clinical studies of fixed tooth-supported prostheses, and to assess the quality of evidence with an emphasis on the assessment of the reporting of outcome measurements. Multiple hypotheses were generated to compare the effect of study type on different outcome modifiers and to compare the quality of publications before and after January 2005. Materials and Methods An electronic search was conducted using specific databases (MEDLINE via Ovid, EMBASE via Ovid, Cochrane Library) through July 2012. This was complemented by hand searching the past 10 years of issues of the Journal of Oral Rehabilitation, Journal of Prosthetic Dentistry, Journal of Prosthodontics, and the International Journal of Prosthodontics. All experimental and observational clinical studies evaluating survival, success, failure, and complications of tooth-supported extracoronal fixed partial dentures, crowns, and onlays were included. No restrictions on age or follow-up time were placed. Results The electronic search generated 14,869 papers, of which 206 papers were included for full-text review. Hand-searching added 23 papers. Inclusion criteria were met by 182 papers and were included for the review. The majority were retrospective studies. Only 8 (4.4%) were randomized controlled trials. The majority of the studies measured survival and failure, and few studies recorded data on success; however, more than 60% of the studies failed to define survival, success, and failure. Many studies did not use any standardized criteria for assessment of the quality of the restorations and, when standardized criteria were used, they were modified, thereby not allowing for comparisons with other studies. There was an increase of 21.8% in the number of studies evaluating outcome measurements of all-ceramic restorations in past 8 years. Conclusions Prosthodontic literature presents with a reduced percentage of RCTs compared to other disciplines in dentistry. The overall quality of recording prosthodontic outcome measurements has not improved greatly in the past 8 years. PMID:24947268

2007-10-01
The aim of this study was to provide a quantitative view of the utilisation of the c-fos immunohistochemical method. Articles including the term "c-fos" in their title, abstract or keywords and published in 2004 were retrieved from the Current Content/Life Sciences or Current Content/Clinical Medicine collection of the SCI database. The 933 article-type documents retained were distributed in almost all the sub-disciplines of the Life Sciences and Clinical Medicine, but were principally published in the field of neuroscience. They were authored by researchers from 44 countries - the most prolific were the USA (435 articles), Japan (135) and the UK (55). The 933 articles were published in 283 different journals; all but one of the top-20 most prolific journals are in the Life Sciences discipline, and their Impact Factors ranged from 2.0 to 7.9. A comparison of the USA and the European Union scientific profiles is also made.

Edelmayer, L W; Fenton, J E; Yellin, S A; Shearer, D J; Coelho, D H
2018-06-12
To analyse publication and citations trends of case reports within otolaryngology - head and neck surgery literature, with specific attention to the most-cited reports.Study designDatabase query. Web of Science was searched for article type 'case reports' published in the leading otolaryngology - head and neck surgery journals since 1945. Variables including publication dates, citation dates and numbers, author, author number, and others were recorded and analysed for trends. The reports with the most citations (classics) were further studied. Of nearly 67 000 published articles in leading otolaryngology - head and neck surgery journals, the overall number of case reports as a percentage of the total has substantially decreased over time. A total of 110 case report classics were identified for which citations have increased. Although the case report may not be worthy of its tarnished record, declining trends in publication suggest a limited future for this valuable research and educational resource.

Towards a standards-compliant genomic and metagenomic publication record
DOE Office of Scientific and Technical Information (OSTI.GOV)
Fenner, Marsha W; Garrity, George M.; Field, Dawn
2008-04-01
Increasingly we are aware as a community of the growing need to manage the avalanche of genomic and metagenomic data, in addition to related data types like ribosomal RNA and barcode sequences, in a way that tightly integrates contextual data with traditional literature in a machine-readable way. It is for this reason that the Genomic Standards Consortium (GSC) formed in 2005. Here we suggest that we move beyond the development of standards and tackle standards-compliance and improved data capture at the level of the scientific publication. We are supported in this goal by the fact that the scientific community ismore » in the midst of a publishing revolution. This revolution is marked by a growing shift away from a traditional dichotomy between 'journal articles' and 'database entries' and an increasing adoption of hybrid models of collecting and disseminating scientific information. With respect to genomes and metagenomes and related data types, we feel the scientific community would be best served by the immediate launch of a central repository of short, highly structured 'Genome Notes' that must be standards-compliant. This could be done in the context of an existing journal, but we also suggest the more radical solution of launching a new journal. Such a journal could be designed to cater to a wide range of standards-related content types that are not currently centralized in the published literature. It could also support the demand for centralizing aspects of the 'gray literature' (documents developed by institutions or communities) such as the call by the GSCl for a central repository of Standard Operating Procedures describing the genomic annotation pipelines of the major sequencing centers. We argue that such an 'eJournal', published under the Open Access paradigm by the GSC, could be an attractive publishing forum for a broader range of standardization initiatives within, and beyond, the GSC and thereby fill an unoccupied yet increasingly important niche within the current research landscape.« less

Randomized controlled trials (RCTs) are considered the gold standard for assessing efficacy and short-term harm of medicines. However, several studies have come to the conclusion that harm is less well reported than efficacy outcomes. To describe harm reporting in publications on dermatological RCTs and assess parameters that could influence the quality of harm reporting. Methodologic systematic review of dermatologic RCTs published from 2010 to 2014 in 5 dermatological journals. Among 110 assessed publications on RCTs, 80 (73%) adequately reported harm and 52% adequately reported its severity. Overall, 40% of the assessed manuscripts perfectly reported and discussed harm. The adequate reporting of harm was significantly associated with the type of trial (odds ratio [OR] 4.41, 95% confidence interval [CI] 1.60-12.35 for multicenter compared with monocentric trials) and having a predefined method for collecting harm data (OR 5.93, 95% CI 2.26-15.56). Reporting of harm severity was better in pharmacologic trials (OR 6.48, 95% CI 2.00-21.0) compared with nonpharmacologic trials and in trials for which a method for collecting harm (OR 5.65, 95% CI 2.00-16.4) and its severity (OR 3.60, 95% CI 1.00-12.8) was defined before the study onset. Assessment was restricted to RCTs and 5 dermatological journals. Harm is quite well reported in dermatologic journals. Efforts should be made on reporting severity of harm.

There is a paucity of information about the oral pathology related articles published in a pathology journal. This study aimed to audit the oral pathology related articles published in Iranian Journal of Pathology (Iran J Pathol) from 2006 to 2015. Bibliometric analysis of issues of Iran J Pathol from 2006 to 2015 was performed using web-based search. The articles published were analyzed for type of article and individual topic of oral pathology. The articles published were also checked for authorship trends. Out of the total 49 published articles related to oral pathology, case reports (21) and original articles (18) contributed the major share. The highest number of oral pathology related articles was published in 2011, 2014 and 2015 with 8 articles each and the least published year was 2012 with 1 article. Among the oral pathology related articles published, spindle cell neoplasms (7) followed by salivary gland tumors (5), jaw tumors (4), oral granulomatous conditions (4), lymphomas (4), oral cancer (3) and odontogenic cysts (3) form the major attraction of the contributors. The largest numbers of published articles related to oral pathology were received from Tehran University of Medical Sciences; Tehran (7) followed by Mashhad University of Medical Sciences, Mashhad (6) and Shahid Beheshti University of Medical Sciences, Tehran (5). This paper may be considered as a baseline study for the bibliometric information regarding oral pathology related articles published in a pathology journal.

Hypertension, Diabetes Type II, and Their Association: Role of Arterial Stiffness.
Smulyan, Harold; Lieber, Ari; Safar, Michel E
2016-01-01
In patients with both hypertension and type II diabetes, the systolic blood pressure (SBP) increases linearly with age, while that of diastolic blood pressure (DBP) declines curvilinearly as early as age 45, all suggesting the development of increased arterial stiffness. Increased stiffness is an important, independent, and significant risk predictor in subjects with hypertension and diabetes. In patients with both diseases, stiffness assessed at the same mean arterial pressure (MAP) was significantly higher in diabetic patients. Arterial stiffness is related to age, heart rate (HR), and MAP, but in diabetic patients, it also related to diabetes duration and insulin treatment (IT). In the metabolic syndrome (MetSyn), diabetes also acts on the small arteries through capillary rarefaction to reduce the effective length of the arterial tree, increases the reflected pulse wave and thus the pulse pressure (PP). These studies indicate that diabetes and hypertension additively contribute to increased pulsatility and suggest that any means to reduce stiffness would be beneficial in these conditions. © American Journal of Hypertension, Ltd 2015.

OBJECTIVE: To identify global research trends in the use of acupuncture to treat cerebral infarction. DATA RETRIEVAL: We performed a bibliometric analysis of studies on the use of acupuncture to treat cerebral infarction published during 2002–2011, retrieved from Scopus, using the key words of acupuncture and cerebral infarction or ischemic stroke. SELECTION CRITERIA: Inclusion criteria: peer-reviewed articles on the use of acupuncture to treat cerebral infarction indexed in Scopus and published between 2002 and 2011; types of publications were original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items. Exclusion criteria: articles that required manual searching or telephone access; documents that were not published in the public domain; and corrected papers. MAIN OUTCOME MEASURES: (a) Annual publication output; (b) language of publication; (c) type of publication; (d) key words of publication; (e) publication by research field; (f) publication by journal; (g) publication by country and institution; (h) publication by author; (i) most-cited papers between 2002 and 2006; and (j) most-cited papers between 2007 and 2011. RESULTS: A total of 160 publications on the use of acupuncture to treat cerebral infarction from 2002–2011 were retrieved from Scopus. The number of publications increased gradually over the 10-year study period; most were written in Chinese or English. Articles and reviews constituted the major types. The most frequent key word used was acupuncture. The most prolific journals in this area were Zhongguo Zhen Jiu and the Chinese Journal of Clinical Rehabilitation. Of the 160 publications retrieved, half came from Chinese authors and institutions. Tianjin University of Traditional Chinese Medicine was the most prolific research institute. Two papers were cited 30 times; they were published in 2002 and 2009, respectively. CONCLUSION: In the field of neuroscience, there is little literature on acupuncture for cerebral infarction. The most-cited papers were cited 30 times in the past 3 years. We believe that, with advances in the study of mechanisms in neurobiology, research on acupuncture will also advance and will become the concern of more scholars. PMID:25317148
Selective Photonic Disinfection; A ray of hope in the war against pathogens
NASA Astrophysics Data System (ADS)
Tsen, Shaw-Wei D.; Tsen, Kong-Thon
2016-06-01
Pathogens such as viruses and bacteria are among the greatest threats to human health worldwide. In today's era of population growth and international travel, new technologies are desperately needed to combat the spread of known and emerging pathogens. This book presents a new concept for pathogen inactivation called selective photonic disinfection (SEPHODIS). The SEPHODIS technology inactivates pathogens by mechanical means, a total paradigm shift from traditional chemical and physical methods. The unique strength of SEPHODIS resides in its capability to inactivate pathogens while preserving desirable materials such as human cells and proteins. The technology also avoids the need to use chemicals, drastically reducing the risk of side effects. These properties make SEPHODIS ideal for important biomedical applications such as safeguarding blood products and therapeutics against pathogens, as well as producing effective and safe vaccines to combat infectious disease. Written in a style that is both technically informative and easy to comprehend for the layman reader, this book illustrates the story of SEPHODIS from its initial discovery and bench studies to its real-world applications.

Introduction Integrated care could not only fix up fragmented health care but also improve the continuity of care and the quality of life. Despite the volume and variety of publications, little is known about how ‘integrated care’ has developed. There is a need for a systematic bibliometric analysis on studying the important features of the integrated care literature. Aim To investigate the growth pattern, core journals and jurisdictions and identify the key research domains of integrated care. Methods We searched Medline/PubMed using the search strategy ‘(delivery of health care, integrated [MeSH Terms]) OR integrated care [Title/Abstract]’ without time and language limits. Second, we extracted the publishing year, journals, jurisdictions and keywords of the retrieved articles. Finally, descriptive statistical analysis by the Bibliographic Item Co-occurrence Matrix Builder and hierarchical clustering by SPSS were used. Results As many as 9090 articles were retrieved. Results included: (1) the cumulative numbers of the publications on integrated care rose perpendicularly after 1993; (2) all documents were recorded by 1646 kinds of journals. There were 28 core journals; (3) the USA is the predominant publishing country; and (4) there are six key domains including: the definition/models of integrated care, interdisciplinary patient care team, disease management for chronically ill patients, types of health care organizations and policy, information system integration and legislation/jurisprudence. Discussion and conclusion Integrated care literature has been most evident in developed countries. International Journal of Integrated Care is highly recommended in this research area. The bibliometric analysis and identification of publication hotspots provides researchers and practitioners with core target journals, as well as an overview of the field for further research in integrated care.

We examined the trends of quantitative research over the past 10 years in the Journal of Marital and Family Therapy (JMFT). Specifically, within the JMFT, we investigated the types and trends of research design and statistical analysis within the quantitative research that was published in JMFT from 2005 to 2014. We found that while the amount of peer-reviewed articles have increased over time, the percentage of quantitative research has remained constant. We discussed the types and trends of statistical analysis and the implications for clinical work and training programs in the field of marriage and family therapy. © 2016 American Association for Marriage and Family Therapy.

The aim of this systematic literature review was to evaluate which type of periodontal preventive and therapeutic approaches presents superior outcomes in patients with Down syndrome (DS). Studies reporting different methods of periodontal care from DS patients were considered eligible. Included clinical studies should indicate at least two periodontal parameters in different periods of assessment. Screening of the articles, data extraction and quality assessment were conducted independently and in duplicate. Electronic search according to the PICO search, with both Key-words and MESH terms were conducted in MEDLINE, EMBASE and CENTRAL databases until March 2016. Manual search was conducted in four journals, namely Journal of Periodontology, Journal of Clinical Periodontology, Journal of Periodontal Research and Special Care in Dentistry and their electronic databases were searched. Electronic and manual search resulted in 763 papers, and of them 744 were excluded after title/abstract assessment. The full text of 19 potentially eligible publications was screened and 9 studies met inclusion criteria. The results demonstrated the importance to introduce youngest DS patients in preventive programs, as well as participation of parents, caregivers or institutional attendants in supervising/performing oral hygiene. In studies with higher frequency of attendance, all age groups presented superior preventive and therapeutic results, irrespective of the therapeutic approach used (surgical/nonsurgical/periodontal care program). The important factors for reducing periodontal parameters were the frequency of the appointments and association with chlorhexidine/plaque disclosing agents as adjuvant treatment. This systematic review demonstrated that early introduction in periodontal care, participation of parents/caregivers/institutional attendants, frequency of attendance and association with chemical adjuvants (independently of the periodontal treatment adopted) seems to improve periodontal outcomes in preventive and periodontal treatment of DS patients.

Randomized clinical trials (RCTs) provide high-quality evidence for clinical decision-making. Trial registration is one of the many tools used to improve the reporting of RCTs by reducing publication bias and selective outcome reporting bias. The purpose of our study is to examine whether RCTs published in the top 6 general anesthesiology journals were adequately registered and whether the reported primary and secondary outcomes corresponded to the originally registered outcomes. Following a prespecified protocol, an electronic database was used to systematically screen and extract data from RCTs published in the top 6 general anesthesiology journals by impact factor (Anaesthesia, Anesthesia & Analgesia, Anesthesiology, British Journal of Anaesthesia, Canadian Journal of Anesthesia, and European Journal of Anaesthesiology) during the years 2007, 2010, 2013, and 2015. A manual search of each journal's Table of Contents was performed (in duplicate) to identify eligible RCTs. An adequately registered trial was defined as being registered in a publicly available trials registry before the first patient being enrolled with an unambiguously defined primary outcome. For adequately registered trials, the outcomes registered in the trial registry were compared with the outcomes reported in the article, with outcome discrepancies documented and analyzed by the type of discrepancy. During the 4 years studied, there were 860 RCTs identified, with 102 RCTs determined to be adequately registered (12%). The proportion of adequately registered trials increased over time, with 38% of RCTs being adequately registered in 2015. The most common reason in 2015 for inadequate registration was registering the RCT after the first patient had already been enrolled. Among adequately registered trials, 92% had at least 1 primary or secondary outcome discrepancy. In 2015, 42% of RCTs had at least 1 primary outcome discrepancy, while 90% of RCTs had at least 1 secondary outcome discrepancy. Despite trial registration being an accepted best practice, RCTs published in anesthesiology journals have a high rate of inadequate registration. While mandating trial registration has increased the proportion of adequately registered trials over time, there is still an unacceptably high proportion of inadequately registered RCTs. Among adequately registered trials, there are high rates of discrepancies between registered and reported outcomes, suggesting a need to compare a published RCT with its trial registry entry to be able to fully assess the quality of the study. If clinicians base their decisions on evidence distorted by primary outcome switching, patient care could be negatively affected.
Bibliometric analysis of poison center-related research published in peer-review journals.
Forrester, M B
2016-07-01
Poison centers advance knowledge in the field of toxicology through publication in peer-review journals. This investigation describes the pattern of poison center-related publications. Cases were poison center-related research published in peer-review journals during 1995-2014. These were identified through searching the PubMed database, reviewing the tables of contents of selected toxicology journals, and reviewing abstracts of various national and international meetings. The following variables for each publication were identified: year of publication, journal, type of publication (meeting abstract vs. other, i.e. full article or letter to the editor), and the country(ies) of the poison center(s) included in the research. Of the 3147 total publications, 62.1% were meeting abstracts. There were 263 publications in 1995-1999, 536 in 2000-2004, 999 in 2005-2009, and 1349 in 2010-2014. The publications were in 234 different journals. The journals in which the highest number of research was published were Clinical Toxicology (69.7%), Journal of Medical Toxicology (2.2%), and Veterinary and Human Toxicology (2.1%). The research was reported from 62 different countries. The countries with the highest number of publications were the United States (67.9%), United Kingdom (6.5%), Germany (3.9%), France (2.5%), and Italy (2.4%). The number of publications increased greatly over the 20 years. Although the publications were in a large number of journals, a high proportion of the publications were in one journal. While the research came from a large number of countries, the preponderance came from the United States. © The Author(s) 2015.

Subtle but widespread deficit in the cortical and subcortical grey matter is a consistent neuroimaging observation in schizophrenia. Several studies have used voxel based morphometry (VBM) to investigate the nature of this structural deficit. We conducted a diagnostic test review to explore the diagnostic potential of VBM in differentiating schizophrenia from other types of first-episode psychoses. © The Author 2016.

Objectives: The objectives are to determine how medical faculty members use scholarly journals, whether print or electronic journals are read more, whether there is a pattern among types of users, and what similarities and differences there are between the use of journals by medical faculty and faculty in other disciplines. Methods: Medical faculty of the University of Tennessee Health Science Center (UTHSC) multi-campus system were surveyed, and their responses estimated using critical incident technique to characterize the different aspects of their use of print and electronic journals. Results: Medical faculty read a great deal, especially compared to scientists. The most frequently reported principal purpose of reading is to support their primary research (30% of reading). The majority of reading comes from recently published articles, mostly from personal subscriptions. Medical faculty continue to rely on print journals (approximately 70% of readings) versus electronic journals. Age of faculty does not appear to influence the choice of print or electronic format. Medical faculty read more articles than others on average and need information digested and verified in a way to save them time. Convenience and currency are highly valued attributes. Conclusions: It can be asserted that librarians and publishers must find ways to provide the attributes of convenience and currency and match the portability of personal subscriptions in an electronic journal format for medical faculty.

Asian scientists have now increasingly begun to contribute to globalization; yet it is not clear whether publishing in the field of urology is paralleled by elevated cross-continental scientific publishing. An exemplary bibliometric analysis of urologic journals from 3 different continents was conducted between 2002 and 2012. Based on the ISI Web of Knowledge Journal Citation Reports, 2 urologic journals with similar impact factors (IFs) in 2013 were selected from Europe ('British Journal of Urology International', 'World Journal of Urology'), Asia ('International Journal of Urology', 'Asian Journal of Andrology') and North America ('Urologic Oncology-Seminars and Original Investigations', 'Urology'). The home continent of the journal, the workplace continental affiliation of the last author, article type (clinical, experimental or review) as well as the IF were documented. Most authors published their manuscripts in journals from the same continent in which they worked. However, a significant increase in cross-continental publishing was apparent from 2002 to 2012. Asians publishing in North America increased from 17% in 2002 to 35% in 2012. Europeans also increased the number of articles they published in North American journals, while publications from North American authors were shifted towards both European and Asian journals. Experimental and clinical articles showed significant increases in cross-continental publishing, while review publishing showed no significant change. The average IF for authors from all 3 continents increased from 2002 to 2012 (p < 0.001). The largest increase in the IF was found for Asian authors (0.11 per year). Cross-continental publication significantly increased during the period from 2002 to 2012. The impact that the Asian authors have experienced was found to be gradually impacting the North American and European colleagues. © 2015 S. Karger AG, Basel.

Research papers authored by Medical Physicists address a large spectrum of oncologic, imaging, or basic research problems; exploit a wide range of physical and engineering methodologies; and often describe the efforts of a multidisciplinary research team. Given dozens of competing journals accepting medical physics articles, it may not be clear to an individual author which journal is the best venue for disseminating their work to the scientific community. Relevant factors usually include the Journal’s audience and scientific impact, but also such factors as perceived acceptance rate, interest in their topic, and quality of service. The purpose of this symposium ismore » to provide the medical physics community with an overview of scope, review processes, and article guidelines for the following journals: Radiology, Medical Physics, International Journal of Radiation Biology and Physics, Journal of Applied Clinical Medical Physics, and Practical Radiation Oncology. Senior members of the editorial board for each journal will provide details as to the journals review process, for example: single blind versus double blind reviews; open access policies, the hierarchy of the review process in terms of editorial board structure; the reality of acceptance, in terms of acceptance rate; and the types of research the journal prefers to publish. Other journals will be discussed as well. The goal is to provide for authors guidance before they begin to write their papers, not only for proper formatting, but also that the readership is appropriate for the particular paper, hopefully increasing the quality and impact of the paper and the likelihood of publication. Learning Objectives: To review each Journal’s submission and review process Guidance as to how to increase quality, impact and chances of acceptance To help decipher which journal is appropriate for a given work A.

[Communication of scientific fraud].
Zeitoun, Jean-David; Rouquette, Sébastien
2012-09-01
There is for a scientific journal several levels of communication depending of the degree of suspicion or certainty of a case of error or fraud. The task is increasingly difficult for journal editors as disclosed cases of fraud are more common and scientific communication on this topic is growing. Biomedical fraud is fairly little reported by the mainstream press and causes of this low interest are not currently well understood. The difficulty of processing this type of news for journalists appears to be one possible reason. The potentially numerous and significant consequences of fraud on health professionals are poorly documented. Though it is likely to cause a feeling of distrust and create controversy, the impact of fraud on the general public is poorly studied and appears multifactorial.

The purpose of this study was to identify types and trends in industry sponsorship of plastic surgery research since the establishment of conflict-of-interest reporting policies in plastic surgery. The authors analyzed the frequency and types of self-reported conflicts of interest in the plastic surgery literature since the adoption of reporting policies in 2007. All original articles that met the authors' inclusion criteria and were published in the following three journals from 2008 to 2013 were included: Annals of Plastic Surgery, Plastic and Reconstructive Surgery, and Journal of Plastic, Reconstructive & Aesthetic Surgery. A multivariate regression analysis was performed to determine what study-specific variables were associated with conflict-of-interest disclosures. A total of 3722 articles were analyzed. The incidence of conflicts of interest increased from 14 percent in 2008 to 24 percent in 2009. However, thereafter, the incidence of conflicts of interest decreased steadily from 21 percent in 2010 to 9 percent in 2013. Furthermore, the authors' analysis revealed that from 2008 to 2013, industry decreased direct research support but steadily increased the rate of consultantships (p < 0.001). A multivariate regression analysis revealed that, after adjusting for potential confounders, self-reported conflicts of interest have decreased since 2008 (p = 0.03) and the prevalence of conflicts of interest differs by plastic surgery subspecialty (p < 0.0001), country of origin (p < 0.0001), and journal of publication (p = 0.05). If self-reporting of conflicts of interest is assumed to be accurate, the number of surgeon-reported conflicts of interest in plastic surgery declined overall. Although the absolute number of consultantships did not change, the rate of consultantships rather than direct research support increased over this period.

Clinical trial registration in physical therapy journals: a cross-sectional study.
Babu, Abraham Samuel; Veluswamy, Sundar Kumar; Rao, Pratiksha Tilak; Maiya, Arun G
2014-01-01
Clinical trial registration has become an important part of editorial policies of various biomedical journals, including a few physical therapy journals. However, the extent to which editorial boards enforce the need for trial registration varies across journals. The purpose of this study was to identify editorial policies and reporting of trial registration details in MEDLINE-indexed English-language physical therapy journals. This study was carried out using a cross-sectional design. Editorial policies on trial registration of MEDLINE-indexed member journals of the International Society of Physiotherapy Journal Editors (ISPJE) (Journal of Geriatric Physical Therapy, Journal of Hand Therapy, Journal of Neurologic Physical Therapy, Journal of Orthopaedic and Sports Physical Therapy, Journal of Physiotherapy [formerly Australian Journal of Physiotherapy], Journal of Science and Medicine in Sport, Manual Therapy, Physical Therapy, Physical Therapy in Sport, Physiotherapy, Physiotherapy Research International, Physiotherapy Theory and Practice, and Revista Brasileira de Fisioterapia) were reviewed in April 2013. Full texts of reports of clinical trials published in these journals between January 1, 2008, and December 31, 2012, were independently assessed for information on trial registration. Among the 13 journals, 8 recommended trial registration, and 6 emphasized prospective trial registration. As of April 2013, 4,618 articles were published between January 2008 and December 2012, of which 9% (417) were clinical trials and 29% (121/417) of these reported trial registration details. A positive trend in reporting of trial registration was observed from 2008 to 2012. The study was limited to MEDLINE-indexed ISPJE member journals. Editorial policies on trial registration of physical therapy journals and a rising trend toward reporting of trial registration details indicate a positive momentum toward trial registration. Physical therapy journal editors need to show greater commitment to prospective trial registration to make it a rule rather than an option.

Randomized controlled trials are one of the most reliable resources for assessing the effectiveness and safety of medical treatments. Low quality randomized controlled trials carry a large bias that can ultimately impair the reliability of their conclusions. The present study aimed to evaluate the quality of randomized controlled trials published in International Journal of Urology by using multiple quality assessment tools. Randomized controlled trials articles published in International Journal of Urology were found using the PubMed MEDLINE database, and qualitative analysis was carried out with three distinct assessment tools: the Jadad scale, the van Tulder scale and the Cochrane Collaboration Risk of Bias Tool. The quality of randomized controlled trials was analyzed by publication year, type of subjects, intervention, presence of funding and whether an institutional review board reviewed the study. A total of 68 randomized controlled trial articles were published among a total of 1399 original articles in International Journal of Urology. Among these randomized controlled trials, 10 (2.70%) were from 1994 to 1999, 23 (4.10%) were from 2000 to 2005 and 35 (4.00%) were from 2006 to 2011 (P = 0.494). On the assessment with the Jadad and van Tulder scale, the numbers and percentage of high quality randomized controlled trials increased over time. The studies that had institutional review board reviews, funding resources or that were carried out in multiple institutions had an increased percentage of high quality articles. The numbers and percentage of high-quality randomized controlled trials published in International Journal of Urology have increased over time. Furthermore, randomized controlled trials with funding resources, institutional review board reviews or carried out in multiple institutions have been found to be of higher quality compared with others not presenting these features. © 2013 The Japanese Urological Association.
The 100 Most-Cited Articles in Visceral Surgery: A Systematic Review.
Müller, Martin; Gloor, Beat; Candinas, Daniel; Malinka, Thomas
2016-01-01
Even though citation analysis has several limitations, it is a commonly used tool to determine the impact of scientific articles in different research fields. The study aims to identify and systematically review the 100 most cited articles in the field of visceral surgery focusing on papers that modified therapeutic concepts and influenced the surgeons' decision making. The 100 most cited clinical articles in visceral surgery were identified using Journal Citation Reports and Science Citation Index Expanded of the Web of Science (Thomson Reuters, Philadelphia, Pa., USA). Data for characterization of the articles were determined: Number of citations, research topic, journal, publication time, authorship, country of origin, type of article and level of evidence if reasonable. The 100 most cited articles were published in 17 journals; 72 articles were found in the 3 journals: New England Journal of Medicine (38), Annals of Surgery (21) and Lancet (13). The oldest article was published in 1908 in Annals of Surgery (ranked 76th) and the most recent in 2012 in Lancet (65th). Eighty articles were published between 1990 and 2010. The number of citations ranged from 667 to 4,666 (median 925). The leading country of origin was the United States with 39 articles, followed by articles originating from more than one country (30). There were 45 interventional studies (27 randomized controlled trials), 32 observational studies, 19 reviews and 4 guidelines, definitions or classifications. The level of evidence was low (IV) in 42 articles and high in 35 articles (Ia or Ib). A high number of citations did not reflect a high level of evidence. The topics and research questions of the identified articles covered a large area of visceral surgery. Some of the milestones in visceral surgery were identified. The high impact measured by citations did not reflect a high quality of research (level of evidence) in a considerable number of publications. © 2016 S. Karger AG, Basel.
Misalignment in Gas Foil Journal Bearings: An Experimental Study
NASA Technical Reports Server (NTRS)
Howard, Samuel A.
2008-01-01
As gas foil journal bearings become more prevalent in production machines, such as small gas turbine propulsion systems and microturbines, system-level performance issues must be identified and quantified in order to provide for successful design practices. Several examples of system-level design parameters that are not fully understood in foil bearing systems are thermal management schemes, alignment requirements, balance requirements, thrust load balancing, and others. In order to address some of these deficiencies and begin to develop guidelines, this paper presents a preliminary experimental investigation of the misalignment tolerance of gas foil journal bearing systems. Using a notional gas foil bearing supported rotor and a laser-based shaft alignment system, increasing levels of misalignment are imparted to the bearing supports while monitoring temperature at the bearing edges. The amount of misalignment that induces bearing failure is identified and compared to other conventional bearing types such as cylindrical roller bearings and angular contact ball bearings. Additionally, the dynamic response of the rotor indicates that the gas foil bearing force coefficients may be affected by misalignment.
[Scientific articles in the Icelandic Medical Journal 2004-2008: an overview].
Gudbjartsson, Tómas; Sigurdsson, Engilbert
2009-10-01
In the past 5 years the Icelandic Medical Journal has undergone many changes during a period of flourishing research in Iceland. The process of reviewing and editing scientific articles has been revised since the Journal joined the Medline database in 2005 and the proportion of rejected articles has risen. New columns have been launched covering medical history, professionalism, ethics and hobbies of the medical profession. We categorized all scientific articles from the period 2004-2008, that is research articles, review articles, case reports and clinical guidelines, according to types of articles and to which medical speciality or subspeciality the publication should belong. The number of scientific articles rose during the period but the number of research articles remained around 20 most years during the period. The relative proportion of research articles therefore fell whereas the number and proportion of review articles and case reports increased. Clinical guidelines ceased to appear in the Journal. The contribution of individual specialities to the Journal varied widely. Researchers amongst doctors and related professions need be encouraged to submit scientific articles to the Journal. The publication of scientific articles in English in the web-based form of the Journal may prove to be stimulating in this regard for Icelandic doctors abroad as well as for some researchers in Iceland.

The aim of this study was to analyze current scientific impact of Ss Cyril and Methodius University of Skopje, Republic of Macedonia in the Scopus Database (1960-2014). Affiliation search of the Scopus database was performed on November 23, 2014 in order to identify published papers from the Ss Cyril and Methodius University of Skopje (UC&M), Republic of Macedonia. A total number of 3960 articles (3055 articles from UC&M, 861 articles from Faculty of Medicine, UC&M, and 144 articles from Faculty of Pharmacy, UC&M) were selected for analysis (1960-2014). SCImago Journal Rank (SJR), Source Normalized Impact per Paper (SNIP) and h-index were calculated from the Scopus database. The number of published papers was sharply increased with maximum of 379 papers in 2012 year. The largest number of papers has been published in Macedonian Journal of Medical Sciences, Journal of Molecular Structure, Lecture Notes in Computer Science, Acta Pharmecutica, and Macedonian Journal of Chemistry and Chemical Engineering. The biggest SJR and SNIP has journal Nephrology Dialysis Transplantation. First three places of the top ten authors belong to Dimirovski GM, Gavrilovska L, and Gusev M. Top three places based on Scopus h-index (total number of published papers) belong to Kocarev L, Stafilov T, and Polenakovic M. The majority of papers originate from UC&M, but significant numbers of papers are affiliated to Faculty of Medicine, Faculty of Pharmacy, and Institute of Chemistry as members of UC&M, as well as Macedonian Academy of Sciences and Arts. Articles are the most dominant type of documents followed by conference papers, and review articles. Medicine is the most represented subject. Officials of the Ss Cyril and Methodius University of Skopje should undertake more effective and proactive policies for journal publishers and their Editorial Boards in order to include more journals from UC&M in the Scopus database.
