Duplicate Publication Rate Decline in Korean Medical Journals

The purpose of this study was to examine trends in duplicate publication in Korean medical articles indexed in the KoreaMed database from 2004 to 2009, before and after a campaign against scientific misconduct launched by the Korean Association of Medical Journal Editors in 2006. The study covered period from 2007 to 2012; and 5% of the articles indexed in KoreaMed were retrieved by random sampling. Three authors reviewed full texts of the retrieved articles. The pattern of duplicate publication, such as copy, salami slicing (fragmentation), and aggregation (imalas), was also determined. Before the launching ethics campaign, the national duplication rate in medical journals was relatively high: 5.9% in 2004, 6.0% in 2005, and 7.2% in 2006. However, duplication rate steadily declined to 4.5% in 2007, 2.8% in 2008, and 1.2 % in 2009. Of all duplicated articles, 53.4% were classified as copies, 27.8% as salami slicing, and 18.8% as aggregation (imalas). The decline in duplicate publication rate took place as a result of nationwide campaigns and monitoring by KoreaMed and KoreaMed Synapse, starting from 2006.

Analysis of PubMed and KoreaMed Indexed Korean Publications on COVID-19

During the coronavirus disease 2019 (COVID-19) pandemic, publications on the disease have exploded globally. The present study analyzed PubMed and KoreaMed indexed COVID-19 publications by Korean researchers from January 1, 2020 to August 19, 2021. A total of 83,549 COVID-19 articles were recorded in PubMed and 1,875 of these were published by Korean authors in 673 journals (67 Korean and 606 overseas journals). The KoreaMed platform covered 766 articles on COVID-19, including 612 by Korean authors. Among the Journal of Korean Medical Science (JKMS) articles on COVID-19, PubMed covered 176 and KoreaMed 141 documents. Korean researchers contributed to 2.2% of global publications on COVID-19 in PubMed. The JKMS has published most articles on COVID-19 in Korea.     

Current Levels of Conflict of Interest Disclosure in Medical Publications from Korea

Medical research should be fully transparent. The aims of this study were to determine the prevalence of author-related conflict of interest (COI) policies and evaluate the actual state of COI disclosure in Korean medical journals. To determine the prevalence of author-related COI policies, we examined the 198 medical journals listed in the KoreaMed database. To investigate the actual state of COI disclosures in published papers, we analyzed the publications in a representative medical journal, the Journal of the Korean Medical Science, from the perspective of the relevance of the ethics of COI disclosure. A total of 164 (82.8%) journals required an author''s statement of COI as a criterion for publication. Of these 164, most of them focused on financial COI, with 101 (61.6%) presenting the information related to COI disclosures as a separate paragraph with a clear title. We identified 114 articles published by the Journal of the Korean Medical Science over a seven-year period, from January, 2006 to December, 2012. Of these, 65 papers (57%) included an author''s statement of COI. We found that the policies of Korean medical journals regarding the disclosure of author COIs are still behind the internationally suggested level.     

Preliminary reports and the rates of publication of follow-up reports in peer-reviewed, indexed journals.

PURPOSE: To test the hypothesis that articles published as "preliminary" or "pilot" reports are followed by more definitive publications in only a minority of cases. METHOD: A survey of Medline was performed for reports published in 1992 in journals listed in the Abridged Index Medicus that had the word "preliminary" or "pilot" in the title. For identified reports, a Medline search of publications in 1992 through 1999 was performed, using lead author's name, second author's name, and senior (last) author's name, and at least one keyword based on the publication title. Preliminary and pilot publications were subdivided by type of study (controlled clinical study, case series, laboratory or nonclinical) and by the report of either positive or negative results. Rates of publication based on study design and publication bias were compared using the chi-square test for statistical significance. RESULTS: The rate of publication of follow-up reports within seven years of the initial publication was 27%. Follow-up studies of controlled clinical studies (40%) were published more frequently than were those of laboratory or nonclinical studies (31%) or case series (22%), but these differences were not significant (p >.10). There was no statistically significant difference in follow-up publication rates based on publication bias. CONCLUSION: Only 27% of studies published as preliminary or pilot reports were subsequently followed by a more definitive publication. While the words preliminary and pilot suggest that publication of further, refined work is pending, this is often not the case.     

Productivity of SCI Korean medical papers: 1996-1997.

In order to investigate the extent and growth of SCI publication activity of Korean medicine, DIALOG's SCISearch database was searched and the number of SCI Korean medical papers in each medical specialty was measured by publication year and by document type for 1996 and 1997. The percentage contribution of Korean medical papers to SCI database and the SCI publication productivity ratio were analyzed for each of 57 medical specialties. The data obtained in this study was compared with the data representing the 1980s and the data for the first half of the 1990s. The absolute productivity of SCI Korean medical papers as measured by the number of SCI Korean papers has increased about ten times from 306 papers in 1990 to 3,261 papers in 1997. More than 15% of SCI Korean publication output has resulted from six Korean medical journals indexed in SCI from 1995. The relative productivity of SCI Korean medical papers as measured by the percentage contribution from Korea to SCI and by its corresponding productivity ratio is not as impressive as the absolute productivity and its growth rate. It has increased three times from 0.245% to 0.642% during the same period. The relative productivity of SCI Korean medical publication output is not as great as the SCI Korean publication output of all sciences combined (1.02%).     

Progress and Prospect: A Bibliometric Analysis of Research Papers by Korean Allergists Over Recent Five Years (2009-2013)

Since the establishment of the academic society in 1972, Korean allergists have made continuous efforts to elucidate pathogenic mechanisms and therapeutic advances for allergic diseases. The present study aimed to summarize recent progress and explore future prospects of research performance by Korean allergists. We performed a comprehensive bibliometric analysis for research papers published in the Science Citation Index (SCI) or SCI-expanded journals by Korean allergists between 2009 and 2013. Research performance was quantitatively analyzed for the numbers of papers by publication year, research type, and main topic. In addition, the performance was also examined for qualitative indices, such as impact factor and citation number. A total of 1,091 papers were identified. The number of publication increased continuously, with an annual increase rate of 12.3%. Clinical and basic studies were the most frequent types of research, and recently the number of epidemiological studies has increased. By research topic, asthma was the most commonly studied, accounting for 20.9% of the total number of publications. Notably, the amount of rhinitis/rhinosinusitis research has risen steeply in 2013. Qualitative analyses also indicated continuous progress; the median impact factor of published journals increased from 1.918 in 2009 to 2.746 in 2013, yielding an annual increase rate of 7.4%. In conclusion, the present analyses identified a continuous increase in the research performance of Korean allergists over a recent 5 year period (2009-2013), both quantitatively and qualitatively. A more significant contribution is expected in the forthcoming era.     

The risk of using the Internet as reference resource: a comparative study

OBJECTIVE: We sought to examine the frequency and the specific problems encountered in accessing Internet references in two leading medical journals during the last 3 years. METHODS: Two investigators independently reviewed all publications in the issues of the New England Journal of Medicine and The Lancet during October 2005 to March 2006, November 2004 to January 2005, and November 2003 to January 2004. We calculated the total number of references and the subset referred to an Internet source of each article. Then, we visited the electronic sources to identify the Internet references and noted the problems of accessibility, if any. When we failed to directly access the reference in the electronic address provided by the authors, we visited the referred website; if this was also inadequate, we performed Google searches to retrieve the missing reference(s). RESULTS: 465/18,850 (2.5%) and 952/24,630 (3.9%) of the reviewed references in the New England Journal of Medicine and The Lancet, respectively, referred to Internet sources; from these we could not access 68/465 (14.6%) and 170/952 (17.9%) in the two journals, respectively. There were increasing proportions of lost Internet references as they age. Searching into the website referred by the authors of the reviewed articles could not provide the missing information in a considerable proportion (62.2%). However, the use of an Internet search engine (Google) helped us to identify references in other websites, reducing the proportion of missing Internet references to 17/465 (3.7%) and 17/952 (1.8%) for the two journals, respectively. CONCLUSIONS: The response "page not found" was commonly encountered when we tried to access Internet references in publications of leading medical journals during the last 3 years. A considerable proportion of missing references was identified with the use of Google search engine. Authors of scientific articles should be aware of the problem of missing Internet references and until well-established Internet archiving solutions are in use, they should choose carefully their Internet references from reliable websites whenever it is impossible to avoid using them.     

Total research productivity in a pathology discipline

AIMS: To investigate the research productivity of all staff in chemical pathology. METHODS: Chemical pathologists or biochemical scientists were identified from publicly available sources. All journals, their impact factors (IFs), and individual publications over the period of 1995 to 1999 were identified from electronic databases. Each publication was subclassified with respect to type of publication, number and position of author, and subspecialty to which the article referred. RESULTS: Research output over the period comprised 6162 articles, originating from 1399 individuals, 264 of whom were medically qualified. Specialty initiated research accounted for 26% of the total publications and 80% of the research was performed in teaching hospitals. Research output was highly skewed because 49% of individuals published a letter or more, 20% published one original piece of research over five years, but only 4% were research active, as defined by one publication each year. International standard research, defined as one paper each year in journals with IF > 4, was achieved by 1% of the profession, mostly aged > 55 years. Skewed distributions of publication rates were found in all age deciles. The possession of higher research degrees correlated with higher output in all age deciles. CONCLUSIONS: Those working in chemical pathology are active in initiating and conducting research, although at a low level. Because longterm activity in research correlates with the possession of higher research degrees and the opportunity to carry out research from early in career pathways, priority should be given to encouraging research in training, given the small and ageing profile of international quality research in the profession in the UK.     

Fate of abstracts presented at the annual meetings of the American association of clinical anatomists

A recent study examined the rate of full‐length research paper publication following abstract presentation at the British association of clinical anatomists (BACA) annual meetings. The accepted standard for research dissemination is peer‐reviewed publication following presentation at a national or international meeting. The study objectives were quantitative assessment of the abstracts presented at the American Association of Clinical Anatomists' (AACA) annual meetings with regards to the rate of subsequent full‐length publication and comparison to BACA publication rates. All abstracts presented at the AACA annual meetings between 2003 and 2010 were analysed. MEDLINE was searched to identify peer‐reviewed publications arising from each presented abstract. In total, 1,120 abstracts were presented with 22.9% (n = 257) subsequently published as full‐length research papers. The mean number of abstracts presented each year was 140.0 ± 35.9. The median time to publication was 16 months. Chi‐squared analysis showed the publication rate of abstracts presented at AACA (22.9%) was not statistically significantly different to BACA (20.4%) (P = 0.09). A total of 11.3% (n = 29) of the articles were published as full‐length research articles before presentation as an abstract at an AACA meeting compared to 5.4% of abstracts presented at a BACA meeting. These rates are lower but comparable to those of surgical specialty meetings. Further work should try to identify any concerning reasons for the reduced rate of abstract publication in anatomical research. Clin. Anat. 30:140–144, 2017. © 2017 Wiley Periodicals, Inc.     

Scientific publication productivity of Korean medical colleges: an analysis of 1988-1999 MEDLINE papers

To identify where the quality research activity has been and is carried out in Korea, and to examine to what extents Korean medical colleges play leading roles in the production of international research papers, we investigated the publication productivity of Korean medical colleges and their medical departments as measured by the number of papers published in foreign journals indexed in MEDLINE. The 12-year period from 1988 to 1999 is covered. A total of 4,881 papers is published in MEDLINE foreign journals by the researchers in Korean medical colleges during the period. The production of MEDLINE papers are concentrated in a few universities. More than 60% of MEDLINE foreign journal papers is published by top five universities 25% by Seoul National University, and 15% by Yonsei University. The newly established medical colleges at the University of Ulsan and Sungkyunkwan University produced outstanding numbers of papers in less than ten years. Radiology has led the internationalization of Korean medical papers. It was the most productive specialty identified in this study. The productivity of Internal medicine is on the rise from the mid-1 990s, and the field began to produce the most number of papers since then.     

Citation and quotation accuracy in three anatomy journals

Citation and quotation errors are common in medical journals. We assessed the prevalence of those errors in gross anatomy journals, where articles often cite old anatomical studies. The study included 199 randomly selected references from articles published in the first 2001 issue of three major gross anatomy journals: Annals of Anatomy, Clinical Anatomy, and Surgical and Radiologic Anatomy. The selected references were checked for accuracy against the original articles. Citation errors were classified as major, intermediate, and minor. Quotation errors were classified as major and minor. Citations errors were found in 27% (54/199) of the references and 38% of them were major errors. Errors occurred in 19% (52/272) of quotations and nearly all (94%) were major. Furthermore, 24% of the quotations were indirect references to a secondary, instead of original, source. There was no statistically significant difference in the rates of citation or quotation errors between the references published before or after the introduction of MEDLINE (chi2 test, P > 0.05) in 1963, and the prevalence of these errors in gross anatomy journals was similar to that found in other medical fields. A high proportion of major citation errors, a very high proportion of major quotation errors, and the substantial number of indirect quotations call for serious editorial action in anatomy journals.

Graduate medical education scholarly activities initiatives: a systematic review and meta-analysis

Background

According to the Accreditation Council for Graduate Medical Education residents “should participate in scholarly activity.” The development of a sustainable, successful resident scholarship program is a difficult task faced by graduate medical education leadership.

Methods

A medical librarian conducted a systematic literature search for English language articles published on scholarly activities initiatives in Graduate Medical Education (GME) between January 2003 and March 31 2017. Inclusion criteria included implementing a graduate medical education research curriculum or initiative designed to enhance intern, resident, or fellow scholarly activities using a control or comparison group. We defined major outcomes as increases in publications or presentations. Random effects meta-analysis was used to compare the rate of publications before and after implementation of curriculum or initiative.

Results

We identified 32 relevant articles. Twenty-nine (91%) reported on resident publications, with 35% (10/29) reporting statistically significant increases. Fifteen articles (47%) reported on regional, national, or international presentations, with only 13% (2/15) reporting a statistically significant increase in productivity. Nineteen studies were eligible for inclusion in the meta-analysis; for these studies, the post-initiative publication rate was estimated to be 2.6 times the pre-intervention rate (95% CI: 1.6 to 4.3; p?<?0.001).

Conclusions

Our systematic review identified 32 articles describing curricula and initiatives used by GME programs to increase scholarly activity. The three most frequently reported initiatives were mentors (88%), curriculum (59%), and protected time (59%). Although no specific strategy was identified as paramount to improved productivity, meta-analysis revealed that the publication rate was significantly higher following the implementation of an initiative. Thus, we conclude that a culture of emphasis on resident scholarship is the most important step. We call for well-designed research studies with control or comparison groups and a power analysis focused on identifying best practices for future scholarly activities curricula and initiatives.

     

A Scopus-Based Analysis of Publication Activity in Kazakhstan from 2010 to 2015: Positive Trends,Concerns, and Possible Solutions

The article analyzes the publication activity of scientific authors from Kazakhstan based on Scopus and SCImago Journal & Country Rank data from 2010 to 2015. The number of indexed multidisciplinary and medical articles from the country has been steadily growing from 2011 onward and this can be due to the adoption of the new Law on Science in that year. Several regulatory legal acts have been issued in recent years aimed at improving the quality of local journals and the international recognition of academic degrees and titles. Publication activity of scientific authors from Kazakhstan was found to be higher than that from other countries in the Central Asian region. However, there are still many unresolved issues related to the English language barrier, lack of indexing status of local journals, and poor topical education on science writing and editing. As such, the number of articles published in ''predatory'' journals remains sizable, and there are concerns over authors'' negligence and plagiarism. The global solution to the discussed problems may be achieved by educating researchers, authors, reviewers, and editors.
