Predicting the number of article citations on the topic of pemphigus vulgaris with the 100 top-cited articles since 2011: A protocol for systematic review and meta-analysis.

BACKGROUND: Pemphigus vulgaris (PV) is a rare autoimmune blistering disease characterized by intraepithelial and mucocutaneous blister formation and erosion. Numerous articles related to PV have been published. However, which articles have a tremendous influence is still unknown, and factors affecting article citation numbers remain unclear. We aimed to visualize the prominent entities using the top 100 most-cited articles on the topic of PV (T100PV), and investigate whether medical subject headings (i.e., MeSH terms) can be used to predict article citations. METHODS: By searching the PubMed Central (PMC) database, the T100PV abstracts since 2011 were downloaded. Citation analysis was performed to compare the dominant entities in article topics, authors, and research institutes using social network analysis (SNA) and Kano diagrams. We examined the MeSH prediction power against article citations using correlation coefficients (CCs). RESULTS: The most cited article (125 times) was authored by Ellebrecht from the University of Pennsylvania in the US. The most productive countries were Germany (28%) and the US (25%). Most articles were published in J Invest Dermatol (16%) and Br J Dermatol (10%). Kasperkiewicz (Germany) and the Normandie University (France) were the most cited authors and research institutes, respectively. The most frequently occurred MeSH terms were administration and dosage, immunology, and metabolism. MeSH terms were evident in the prediction power on the number of article citations (F = 19.77; P < .001). CONCLUSION: A breakthrough was achieved by developing dashboards to display the T100PV. MeSH terms can be used to predict the T100PV citations. These T100PV visualizations can be applied in future studies.

Completeness of reporting for COVID-19 case reports, January to April 2020: a meta-epidemiologic study.

BACKGROUND: The quality of case reports, which are often the first reported evidence for a disease, may be negatively affected by a rush to publication early in a pandemic. We aimed to determine the completeness of reporting (COR) for case reports published on coronavirus disease 2019 (COVID-19). METHODS: We conducted a systematic search of the PubMed database for all single-patient case reports of confirmed COVID-19 published from Jan. 1 to Apr. 24, 2020. All included case reports were assessed for adherence to the CARE (Case Report) 31-item checklist, which was used to create a composite COR score. The primary outcome was the mean COR score assessed by 2 independent raters. Secondary outcomes included whether there was a change in overall COR score with certain publication factors (e.g., publication date) and whether there was a linear relation between COR and citation count and between COR scores and social media attention. RESULTS: Our search identified 196 studies that were published in 114 unique journals. We found that the overall mean COR score was 54.4%. No one case report included all of the 31 CARE checklist items. There was no significant correlation between COR with either citation count or social media attention. INTERPRETATION: We found that the overall COR for case reports on COVID-19 was poor. We suggest that journals adopt common case-reporting standards to improve reporting quality.

Quantifying the scientific interest in surgical training and education: numerical evidence of a PubMed analysis.

The scientific interest (SI) for a given field can be ascertained by quantifying the volume of published research. We quantified the SI in surgical education to clarify the extent of worldwide efforts on this crucial factor required to improve health-care systems. A set of Medical Subject Headings (MeSH) was defined for the PubMed search. The number of Pubmed Indexed Papers (nPIP) relevant to the SI was extracted from database conception to December 2016 and their distribution and evolution by country were analyzed at 10-year intervals. Population Adjusted Index (PAI) and Medical School Adjusted Index (MSAI) analyses were performed for countries with the nPIP > 30. We identified 51,713 articles written in 33 different languages related to surgical education; 87.6% of these were written in English. General surgery was the leading surgical specialty. The overall nPIP doubled every 10 years from 1987 (from 6009 to 13,501, to 26,272) but stabilized at 3707, 3800 and 3433 in the past 3 years, respectively. The PAI and MSAI analyses showed that the USA, United Kingdom, New Zealand, Canada, Australia and Ireland are top producers of published research in surgical education, constituting a combined 62.88% of the nPIP. Our quantification of the change in SI in surgical education and training gives a clear picture of evolution, efforts and leadership worldwide over time. This picture mirrors an international academic society that should encourage all those involved in surgical education to improve efforts in educational research.

Usage Trends of Patient-reported Outcome Measures in Shoulder Literature.

INTRODUCTION: Quantifying patient outcomes is integral in orthopaedic practice, and patient-reported outcome measures (PROMs) assist with this goal and assist clinicians in assessing subjective outcomes (pain, satisfaction, etc.). This study seeks to identify the most highly used PROMs in the shoulder literature and analyze their usage trends. METHODS: PubMed was queried for all shoulder-based articles published in eight selected journals from 2007 to 2017. Articles were assessed for PROM usage, surgical approach, surgical procedure, and disease pathology. Frequency analyses identified the most used PROMs overall, and for each approach, procedure, and pathology. Last, usage trends, question number, validation, and clinician dependence of PROMs with ≥20 uses were analyzed. RESULTS: In total, 1,740 of 2,462 articles (71%) used 105 unique PROMs 4,394 times during the study. PROM usage increased 18%, and the use of multiple PROMs increased by 20%. PROMs with a clinician component increased 21% slower than the baseline. Twenty-two PROMs (17%) had >20 uses, with the most used PROMs being the Constant-Murley Score (783), American Shoulder and Elbow Surgeons Shoulder Score (731), Visual Analog Scale (685), Simple Shoulder Test (372), and the University of California, Los Angeles, Shoulder Rating Scale (274). PROMs demonstrating the greatest usage increase were the EuroQol 5-Dimensions Questionnaire (1,282%), Shoulder Pain and Disability Index (638%), Western Ontario Rotator Cuff Index (632%), Western Ontario Osteoarthritis of the Shoulder Index (582%), and Oxford Shoulder Score (462%)-all without a clinician component. DISCUSSION: PROM usage is increasing, often with multiple PROMs being used to evaluate patient outcomes. PROMs without a clinician component are growing at higher rates than their clinician-dependent counterparts, highlighting an emphasis on patient reporting of outcomes. This study suggests that the American Shoulder and Elbow Surgeons Shoulder Score, Oxford Shoulder Score, Visual Analog Scales-all without a mandatory clinician component and high levels of use-will be the most highly used PROMs moving forward to assess shoulder function.

Scientific Publications in Dentistry in Lithuania, Latvia, and Estonia Between 1996 and 2018: A Bibliometric Analysis.

This study aimed to determine the number and quality of scientific publications in dentistry from the Baltic countries of Lithuania, Latvia, and Estonia between 1996 and 2018 using bibliometric analysis. Web of Science and Scopus were searched to identify scientific publications in dentistry between 1996 and 2018 by authors from centers in Lithuania, Latvia, and Estonia. The annual number of scientific publications, citation rate, and h-index for each publication, and trends in international co-authorship were investigated by country and institution. There were 651 scientific publications in dentistry between 1996 and 2018, by authors from Lithuania (280 publications), Latvia (210 publications), and Estonia (161 publications). Publications from Estonia were ranked highest in qualitative terms (citation rate and h-index), followed by Lithuania, and Latvia. Of 28 authors with at least ten publications, 54% were Lithuanian (15 authors), 25% were Estonian (7 authors), and 21% were Latvian (6 authors). Estonian authors collaborated mainly with Finland (27 publications), Latvian authors with the USA (16 publications), and Lithuanian authors with Canada (26 publications). Most publications came from the academic institutions of the Lithuanian University of Health Sciences (136 publications), the University of Tartu (109 publications), Vilnius University (101 publications), and Riga Stradins University (28 publications). During the past 22 years, authors from Lithuania had the most publications in the field of dentistry, and authors from Estonia had the most cited publications. Authors mainly published in native journals and collaborated with authors in Scandinavia and North America.

The most influential articles in Helicobacter pylori research: A bibliometric analysis.

OBJECTIVE: The number of articles that researchers must be familiar with is increasing, along with the importance of selective searching and summarization. This study aimed to assess and characterize the most influential articles in Helicobacter pylori research. METHODS: We performed a search of the top-100 cited articles using the Web of Science Core Collection (WoSCC) and Google Scholar from their inception to 2018. The top-100 Altmetric Attention Score (AAS) articles based on online media mentions were also searched using the term H pylori. Each article was evaluated for the following characteristics: citation number, title, journal, publication year, and authorship. RESULTS: The citation number for the top-100 WoSCC articles ranged from 44 to 367. Gut published the largest number of articles (11%). In the top-100 Google Scholar articles, Lancet had the largest number of articles (13%); however, among the top-1000 cited articles published after 2012, Helicobacter published the largest number (46%). The largest number of top-100 AAS articles was published by PLOS Pathogens (6%). PubMed Central articles' citations in WoSCC or Google Scholar showed significant correlation with those from each metric; however, AAS showed no correlation. The proportion of basic research was 36%-37% in top-cited articles; but, 52% in the top-100 AAS articles. No time trend in the number of publications or citations of basic/clinical research in the top-100 bibliometrics was found. "Meta-analysis/systematic review," "gastric cancer," "eradication," and "association" were the most influential title words. CONCLUSION: This study presents a detailed list of top-100 articles, journals, authors, and topic title words.

Open access medical journals: Benefits and challenges.

The world of medical science literature is ever increasingly accessible via the Internet. Open access online medical journals, in particular, offer access to a wide variety of useful information at no cost. In addition, they provide avenues for publishing that are available to health care providers of all levels of training and practice. Whereas costs are less with the publishing of online open access journals, fewer resources for funding and technical support also exist. A recent rise in predatory journals, which solicit authors but charge high fees per paper published and provide low oversight, pose other challenges to ensuring the credibility of accessible scientific literature. Recognizing the value and efforts of legitimate open access online medical journals can help the reader navigate the over 11,000 open access journals that are available to date.

Introduction.

This article offers an overview of the life and work of Gerald N. Grob. As part of a generation of scholars intent on overturning the old "Whig history" of medicine, Grob pioneered the use of institutional history as an analytical tool. His work on American psychiatry combined a formidable command of archival sources with a strong commitment to putting medical practice in social context. Grob's personal and political views put him at odds with other scholars of the asylum; he conducted some very public feuds with David Rothman and Andrew Scull. At the same time, he showed a more benevolent side to younger historians interested in psychiatry; he took particular pains to encourage women (including the authors of this introduction) to enter a historical specialty then dominated by men. To honor Grob's legacy as a scholar and a person, this special issue features articles written by several generations of scholars influenced and inspired by his work.

[Training 5th-Year Clinical Pharmacy Students to Collect and Evaluate Information from Original Articles].

　Pharmacists are required to contribute to evidence-based medicine (EBM) by providing drug information, which can be collected from various sources such as books, websites, and original articles. In particular, information from original articles is needed in some situations. For example, original articles by international researchers are used to aid the management of novel in-hospital preparations on which little knowledge is available. We introduced an information evaluation program, the Okayama University Hospital EBM Model, into the clinical training of 5th-year pharmacy students. It aims to enable students to evaluate the validity of novel in-hospital preparations using original articles. This program has improved students' knowledge of EBM, and the satisfaction level of those enrolled was high. In addition, customer satisfaction analysis revealed that the overall degree of student satisfaction was related to their understanding of the necessity for EBM and the difficulty of practical training. In addition, students' achievements were evaluated using rubrics, and that method allowed the achievements of each student to be assessed appropriately. We hope to revise this program with the aim of improving students' understanding of EBM.

The genealogy of the clinical syndrome of mania: signs and symptoms described in psychiatric texts from 1880 to 1900.

In 1800, mania was conceptualized as an agitated psychotic state. By 1900, it closely resembled its modern form. This paper reviews the descriptions of mania in Western psychiatry from 1880 to 1900, when Kraepelin was training and developing his concept of manic-depressive illness. Psychiatric textbooks published 1900-1960 described 22 characteristic manic symptoms/signs the presence of which were recorded in 25 psychiatric textbooks and three other key documents published 1880-1900. Descriptions of mania in these nineteenth century textbooks closely resembled those in the twentieth century, recording a mean (s.d.) of 15.9 (2.3) and 17.0 (2.3) of the characteristic symptoms, respectively (p = 0.12). The frequency with which individual symptoms were reported was substantially correlated in these two periods (r = +0.64). Mendel's 1881 monograph, Kraepelin's first description of mania in 1883 and the entry for mania in Tuke's Dictionary of Psychological Medicine (1892) described a mean (s.d.) of 19 (1.7) of these characteristic symptoms. These descriptions of mania often contained phenomenologically rich descriptions of euphoria, hyperactivity, grandiosity, flight of ideas, and poor judgment. They also emphasized several features not in DSM criteria including changes in character, moral standards and physical appearance, and increased sense of humor and sexual drive. Fifteen authors described key symptoms/signs of mania most reporting elevated mood, motoric hyperactivity and accelerated mental processes. By 1880, the syndrome of mania had been largely stabilized in its modern form. In the formation of his concept of manic-depressive illness, Kraepelin utilized the syndrome of mania as described in the psychiatric community in which he was trained.

An early history of Japanese amyotrophic lateral sclerosis (ALS) and the current significance.

The present review focuses an early history of Japanese amyotrophic lateral sclerosis (ALS) and the current significance in comparison to previously known and newly found reports on Japanese ALS. After a preliminary case report of ALS by Masamichi Hirai on 1890, 2 completed reports were simultaneously published within 2 weeks of 1891 by Momojiro Nakamura and Zenjiro Inoue, followed by Eikichi Watanabe's report on 1892. After Shonosuke Hasegawa's and Hiroshi Kawahara's case reports on 1894-1896, Aihiko Sata first reported an autopsy case of ALS on 1897. The great contribution of Kinnosuke Miura was also introduced for the naming and pathogenesis in the early stage of ALS history in Japan during 1893-1911.

Historical documents on epilepsy: From antiquity through the 20th century.

Historical documents dating back almost 4500years have alluded to the condition of epilepsy, describing signs and symptoms that are well-known today. Epilepsy was thought to be a mystical disorder by almost all Ancient cultures, including the Babylonians, Egyptians, Greeks, Indians, Iranians and Chinese. Hippocrates was the first to de-mystify the condition of epilepsy, providing a more scientific approach to the condition. As the signs and symptoms of epilepsy occurred without an obvious cause, the idea stood that it was a mystical phenomenon of divine punishment. This portrayal persisted through the early centuries of the common era, including the Middle Ages. It was not until the 16th and 17th century that Paracelsus, le Pois and Sylvius started to investigate internal causes for epilepsy. By the beginning of the 18th century, the general opinion on epilepsy was that it was an idiopathic disease residing in the brain and other inner organs. This resulted in Tissot writing the first modern book on epilepsy. Research continued in the 19th century with Jackson describing different types of seizures and many researchers showing interest in electroencephalography (EEG). The 20th century saw more detailed research being done on epilepsy and EEG, in addition to the establishment of many epilepsy-associated medical societies. The goal of this historical documentation is to provide an overview of the most important milestones in the history of epilepsy.

Quality of meta-analyses in major leading gastroenterology and hepatology journals: A systematic review.

BACKGROUND AND AIM: To appraise the current reporting methodological quality of meta-analyses in five leading gastroenterology and hepatology journals, and to identify the variables associated with the reporting quality. METHODS: We systematically searched the literature of meta-analyses in Gastroenterology, Gut, Hepatology, Journal of Hepatology (J HEPATOL) and American Journal of Gastroenterology (AM J GASTROENTEROL) from 2006 to 2008 and from 2012 to 2014. Characteristics were extracted based on the PRISMA statement and the AMSTAR tool. Country, number of patients, funding source were also revealed and descriptively reported. RESULTS: A total of 127 meta-analyses were enrolled in this study and were compared among journals, study years, and other characters. Compliances with the PRISMA statement and the AMSTAR checklist were 20.8 ± 4.2 out of a maximum of 27 and 7.6 ± 2.4 out of a maximum of 11, respectively. Some domains were poorly reported including describing a protocol and/or registration (item 5, 0.0%), describing methods, and giving results of additional analyses (item 16, 45.7% and item 23, 48.0%) for PRISMA and duplicating study selection and data extraction (item 2, 53.5%), and providing a list of included and excluded studies (item 5, 14.2%) for AMSTAR. Publication in recent years showed a significantly better methodological quality than those published in previous years. CONCLUSIONS: This study shows that methodological reporting quality of MAs in the major gastroenterology and hepatology journals has improved in recent years after the publication of the developed PRISMA statement, and it can be further improved.
