RESUMO

El modelo matemático de Lotka describe la relación entre los autores y su productividad dentro de un área de la ciencia. Este estudio se efectuó con el objetivo de comprobar que el comportamiento de la productividad científica de los investigadores del área de Ciencias Médicas y de la Salud, categorizados al año 2016 en el Programa Nacional de Incentivo a los Investigadores (PRONII), cumple con el modelo matemático de Lotka. Con este fin se consideraron las publicaciones alojadas en la Web of Science en las que éstos figuran como primer autor, aplicándose el criterio de primera autoría tal como lo hizo el formulador del modelo, y con filiación a instituciones paraguayas. Se aplicó el modelo a 236 publicaciones generadas por 77 investigadores, observándose que 21 de ellos tenían una sola publicación. Se comprobó que los datos observados no se ajustaban al modelo propuesto por Lotka. Esto motivó a que de los 77 investigadores analizados inicialmente se seleccionaran a 70. A la productividad de estos 70 investigadores se aplicó la forma general del modelo de Lotka y se comprobó que los datos se ajustaban al modelo. Se observó que de cada 10 investigadores muestreados solo 4 contaban con una única publicación, hecho que podría suponer una limitada existencia de autores ocasionales. Estos hallazgos revisten importancia ya que muestran el comportamiento de la relación entre el investigador y su productividad. Asimismo, mediante el modelo establecido es posible bajo determinadas condiciones realizar predicciones de la cantidad de investigadores con determinado número de publicaciones(AU)


Lotka's mathematical model describes the relationship between authors and their productivity within an area of science. This study was carried out with the aim of verifying that the behavior of the scientific productivity of the researchers in the area of Medical Sciences and Health, categorized to 2016 in the National Program of Incentive to Researchers (PRONII), complies with the model mathematical of Lotka. To this purpose, the publications hosted in the Web of Science were considered in which they appear as the first author, applying the criterion of first authorship as the model's formulator did, and with affiliation to Paraguayan institutions. The model was applied to 236 publications generated by 77 researchers, observing that 21 of them had a single publication. It was found that the observed data did not conform to the model proposed by Lotka. This motivated the selection of 70 of the 77 researchers initially analyzed. The overall form of the Lotka's model was applied to the productivity of these 70 researchers and the data was found to fit the model. It was observed that out of every 10 researchers sampled only four had a single publication, fact that could suppose a limited existence of occasional authors. These findings are important because they show the behavior of the relationship between the researcher and his & her productivity. In addition, through the established model it is possible under certain conditions to make predictions of the number of researchers with a certain number of publications(AU)

RESUMO

AIMS: There has been a recent resurgence in interest in combined partial knee arthroplasty (PKA) as an alternative to total knee arthroplasty (TKA). The varied terminology used to describe these procedures leads to confusion and ambiguity in communication between surgeons, allied health professionals, and patients. A standardized classification system is required for patient safety, accurate clinical record-keeping, clear communication, correct coding for appropriate remuneration, and joint registry data collection. MATERIALS AND METHODS: An advanced PubMed search was conducted, using medical subject headings (MeSH) to identify terms and abbreviations used to describe knee arthroplasty procedures. The search related to TKA, unicompartmental (UKA), patellofemoral (PFA), and combined PKA procedures. Surveys were conducted of orthopaedic surgeons, trainees, and biomechanical engineers, who were asked which of the descriptive terms and abbreviations identified from the literature search they found most intuitive and appropriate to describe each procedure. The results were used to determine a popular consensus. RESULTS: Survey participants preferred "bi-unicondylar arthroplasty" (Bi-UKA) to describe ipsilateral medial and lateral unicompartmental arthroplasty; "medial bi-compartmental arthroplasty" (BCA-M) to describe ipsilateral medial unicompartmental arthroplasty with patellofemoral arthroplasty; "lateral bi-compartmental arthroplasty" (BCA-L) to describe ipsilateral lateral unicompartmental arthroplasty with patellofemoral arthroplasty; and tri-compartmental arthroplasty (TCA) to describe ipsilateral patellofemoral and medial and lateral unicompartmental arthroplasties. "Combined partial knee arthroplasty" (CPKA) was the favoured umbrella term. CONCLUSION: We recommend bi-unicondylar arthroplasty (Bi-UKA), medial bicompartmental arthroplasty (BCA-M), lateral bicompartmental arthroplasty (BCA-L), and tricompartmental arthroplasty (TCA) as the preferred terms to classify CPKA procedures.

RESUMO

INTRODUCTION: Over the past 10 years, epilepsy genetics has made dramatic progress. This study aimed to analyze the knowledge structure and the advancement of epilepsy genetics over the past decade based on co-word analysis of medical subject headings (MeSH) terms. METHODS: Scientific publications focusing on epilepsy genetics from the PubMed database (January 2009-December 2018) were retrieved. Bibliometric information was analyzed quantitatively using Bibliographic Item Co-Occurrence Matrix Builder (BICOMB) software. A knowledge social network analysis and publication trend based on the high-frequency MeSH terms was built using VOSviewer. RESULTS: According to the search strategy, a total of 5185 papers were included. Among all the extracted MeSH terms, 86 high-frequency MeSH terms were identified. Hot spots were clustered into 5 categories including: "ion channel diseases," "beyond ion channel diseases," "experimental research & epigenetics," "single nucleotide polymorphism & pharmacogenetics," and "genetic techniques". "Epilepsy," "mutation," and "seizures," were located at the center of the knowledge network. "Ion channel diseases" are typically in the most prominent position of epilepsy genetics research. "Beyond ion channel diseases" and "genetic techniques," however, have gradually grown into research cores and trends, such as "intellectual disability," "infantile spasms," "phenotype," "exome," " deoxyribonucleic acid (DNA) copy number variations," and "application of next-generation sequencing." While ion channel genes such as "SCN1A," "KCNQ2," "SCN2A," "SCN8A" accounted for nearly half of epilepsy genes in MeSH terms, a number of additional beyond ion channel genes like "CDKL5," "STXBP1," "PCDH19," "PRRT2," "LGI1," "ALDH7A1," "MECP2," "EPM2A," "ARX," "SLC2A1," and more were becoming increasingly popular. In contrast, gene therapies, treatment outcome, and genotype-phenotype correlations were still in their early stages of research. CONCLUSION: This co-word analysis provides an overview of epilepsy genetics research over the past decade. The 5 research categories display publication hot spots and trends in epilepsy genetics research which could consequently supply some direction for geneticists and epileptologists when launching new projects.

RESUMO

The deep sea remains the least known biome. Despite this fact, anthropic activities have affected these regions in various ways. The objective of this study was to outline the scientific production scenario based on deep sea research and to analyze trends present in the literature. For this, the bibliographical resources available from the Web of Science (WoS) were surveyed. Between 1987 and 2016, 11,079 articles on the deep sea were published. Growth was over 100% from the first to second decade and 75% from the second to third. The most productive countries were the USA, Germany, France, England and Japan. Of the 404 journals that published articles on the deep sea, 10% accounted for approximately 60% of the total published articles. The keyword with the highest occurrence was "diversity". In the first two decades, the keywords with the greatest "strength" were related to research on mining, especially for hydrocarbons. The description of new species and the analysis of the effects of climate change appear to be emerging trends in deep sea research. Mining continues to be primarily responsible for driving the development of deep sea research.

RESUMO

Recently the two most influential clinical guideline were published for diagnosing and treating hypertension in US and Europe: 2017 American College of Cardiology/American Heart Association (ACC/AHA) and 2018 European Society of Cardiology/European Society of Hypertension (ESC/ESH) Guideline. Though both of them have most in common, the differences in details between guidelines have confused many clinicians in the world. Because guidelines were evidence- based literature, through the analysis of articles cited in guidelines, these similarities and differences could be explained. Bibliometric analysis is a method of quantifying the contents of literature to analyze literature. So using the bibliometric analysis including co-citation network analysis, articles cited in guideline were analyzed. As a result, we figured out that bibliometrics can analyze the influence of the countries, authors and studies on the guidelines, which might affect on the similarities and the differences between both guidelines.

RESUMO

BACKGROUND: Bibliometric analysis highlights the key topics and studies which have shaped the understanding and management of a disease of interest. Here the top-cited articles on oral leukoplakia (OL) were characterized, and research patterns and trends were analyzed. METHODS: A comprehensive search was performed and identified in the Scopus database up to 22 February 2019 for the 100 most-cited articles on OL. RESULTS: The number of citations of the 100 selected articles varied from 116 to 1418, with a mean of 226.7 citations per article. Both Journal of Oral Pathology and Medicine and Oral Surgery Oral Medicine Oral Pathology Oral Radiology were journals with the most articles published (n = 10). Both Hong W.K. and Lippman S. were the most frequently contributing authors (n = 9). United States (n = 43) and M.D. Anderson Cancer Center (n = 12) was most contributing country and institution, respectively. Systematic reviews/meta-analysis (n = 3) and randomized controlled trial (n = 7) were study designs with high evidence level. It is noteworthy that the majority of high-quality articles were the research of chemopreventive drugs (n = 21) and molecular markers/targets (n = 10), which may indicate a trend of key topics. CONCLUSIONS: The results of this first citation analysis of the most-cited articles on OL provide a historical perspective on scientific evolution, and suggest further research trends and clinical practice in the field of OL.

RESUMO

Objective: To understand the research status of occupational asthma and provide information for related research on occupational asthma in the future. Methods: Papers on occupational asthma published from January 1998 to December 2017 had been retrieved in Web of Science core collection database on 9 October 2018. The data retrieval strategies were set as follows: #1 TS=(occupational AND asthma), #2 TS=(occupational AND asthmas), #3 TS=(occupational asthma OR occupational asthmas), #1 OR #2 OR #3. Three thousand two hundred and twelve publications were analyzed by bibliometric and visualizer. Results: Yearly output of articles in this field had been at a stable high level and annual total citations had been increasing. A significant positive correlation was found between the year and annual total citations (r=0.97, P<0.05). The most productive countries were European countries except the United States and Canada. Our country had few literatures accounting for 1.21 percent of the total and the research on occupational asthma in our country started relatively late which were published mainly from 2013 to 2017. The most studied category and journal were public environmental occupational health and Am J Ind Med respectively. "occupational exposure", "allergy" and "rhinitis" were key words with high frequency. Conclusion: Yearly output of publications of occupational asthma has been at a stable high level. Our country should do more research to provide a scientific basis for further prevention and management of occupational asthma.

RESUMO

OBJECTIVE: To determine the history of malpractice literature using forensic science based on a bibliometric and graph theory. METHODS: Documented data were retrieved from the Web of Science Core Collection of Clarivate Analytics on February 22, 2019. We selected articles for the years 1975-2018 from among documents concerning malpractice in the "Medicine, Legal" section and the Science Citation Index Expanded and the Social Sciences Citation Index. Descriptive statistics and co-occurrence analyses were performed using Microsoft Excel 2016, Gephi 0.9.2, and VOSviewer 1.6.10 software. RESULTS: In all, 379 papers and 3160 citing articles were retrieved. The most active publication year was 2013. Relative growth rate showed no malpractice explosion during the study period. Full articles comprised 83.11% of all papers. There were marked differences between the number of publications during the first 21 years and the last 23 years. More studies were published in the United States than in other countries and regions, but malpractice research has diminished during the most recent 3 years. Journal of Law, Medicine and Ethics contributed the most to the field, with 51 documents. The journal with the highest impact factor, however, was Forensic Science International: Genetics. B. Madea topped the list of authors with the highest number of documents. Three clusters were identified, led by authors C. Terranova, B. Madea, and T.A. Brennan, respectively. The malpractice topics that received the most attention were malpractice claims, the types of malpractice, and the causes of medical malpractice. Our study of the citing papers also provided interesting results. CONCLUSION: This bibliometric analysis indicated that studying the field of medical malpractice was poor during 1975-2018. United States was the most prolific country, and B. Madea published more documents in the field. The studies in Medicine, Legal mostly focused on the claims, appraisement methods, and causes of medical malpractice. In the future, forensic scientists should pay more attention to medical malpractice.

RESUMO

BACKGROUND.: This study aimed to evaluate the scientific production of researchers in the field of Medicine who receive a productivity grant from the CNPq. METHODS: The curriculum Lattes of 542 researchers with active grants from 2012 to 2014 were included in the analysis. Grants categories/levels were stratified into three groups according to the CNPq database (1A-B, 1C-D, and 2). RESULTS.: There was a predominance of grants in category 2. During their academic career, Medicine researchers published 76512 articles, with a median of 119 articles per researcher (IQ, interquartile range, 77 to 174). Among the 76512 articles, 36584 (47.8%) were indexed in the Web of Science (WoS database). Researchers in Medicine were cited 643159 times in the WoS database, with a median of 754 citations (IQ, 356 to 1447). There were significant differences among the categories of grants concerning the number of citations in WoS (P <0.001). There was a significant difference in the number of times researchers were cited according to the specialty included in Medicine area. (P < 0.001). CONCLUSION.: Strategies to improve the scientific output qualitatively possibly can be enhanced by the knowledge of the profile of researchers in the field of Medicine.

RESUMO

BACKGROUND: In modern society, there is an increase both in the demand and the duration of computer work. Failure to correct body posture while using the computer has become a serious health hazard. OBJECTIVE: To identify global trends in research related to body posture and visual display terminals (VDTs) using a bibliometric approach. METHODS: In the search process, the keywords (posture *) AND (computer* OR "visual display terminal") were used in the study title section, in the Wos, Scopus and Medline databases. RESULTS: 149 references published between 1970 and 2016 were analyzed. The studied variables were the years of publication, authorship and collaboration index, publication type, titles of journals, most used languages, impact of the publications, as well as content of the articles. CONCLUSIONS: In recent years, the studies on body posture in relation to VDT have been increased both in quantity and quality of publications. The analysis and/or design of the workplace, as well as the elements that make up the computer (keyboard and mouse) are the most researched topics in the area.

RESUMO

OBJECTIVE: The Society for Vascular Surgery (SVS) is a not-for-profit medical society, whose goal is to further advance in vascular health on a global scale. With its 10th anniversary in sight, we were interested in analyzing the impact of a specific scholarship given under the SVS, the International Scholars Program. Our goal was to examine the awardees' characteristics and academic productivity. MATERIALS AND METHODS: We measured the number of peer-reviewed articles, before and after the program, using PubMed® and Google Scholar® (2008-2018) of the scholarship recipients. Editorials, book chapters, letter to editor, and oral/poster presentations were excluded. A survey was sent out to assess the awardees' current status. RESULTS: The average number of applicants/year was 15.4 (standard deviation ± 6.69), with 17.5% females and a mean age of 37 ± 3.37 years, with 5.6 ± 2.30 years status post vascular fellowship. Brazil had the highest number of recipients (n = 5; 18.5%) followed by China (n = 4; 14.8%). No significant difference was noted between each country in terms of publications (P = .45), nor with after the SVS scholarship program compared to before (P = .14, 1.84 vs 2.76). The survey concluded 33% had attended a subsequent SVS meeting after the program, with 27% having presented their research (n = 15). The recipients noted the program helped adopt new practices in clinical management (n = 13, 87%), learn new procedures (n = 10, 67%), gain local/regional leadership (n = 9, 60%), and improve technical skills (n = 8, 53%). The most visited clinical sites were Massachusetts General Hospital and Mayo Clinic (n = 4, 27%). The program was given a 9.1/10 rating. CONCLUSION: The program was successful in maintaining academic productivity by continuing to publish research even after the scholarship, while teaching recipients skills to further improve their career goals. The award remains a competitive process that selects highly skilled recipients and still has much growth and progress to look forward to over the next decade.

RESUMO

OBJECTIVES: The use of citation analysis to identify the first 100 papers in inflammatory bowel disease (IBD) provides unique insights into advances in disease understanding and subsequent follow-up treatment innovations over time. METHODS: The Thomson Reuters Web of Science database with the search terms "inflammatory bowel disease" or "Crohn disease" or "ulcerative colitis" or "colitis" was used to identify all English language full manuscripts for the study. Title, first and senior authors, institution and department of first author, journal, country of origin, year, and topic of each manuscript were analyzed. RESULTS: The top 100 manuscripts were published between 1955 and 2013. 224,809 eligible papers were returned and the median (range) citation number was 1028.5 (719-3957). The country and year with the greatest number of publications were the USA (n = 47), and 2007 (n = 11). Gastroenterology published the highest number of papers (n = 18, 21,083 citations) and The New England Journal of Medicine had the most citations (n = 13, 25,035 citations). CONCLUSIONS: This highly cited list of papers identifies the subjects and authors who have had the greatest impact on IBD research in the last decades, which serves as a reference for researchers and clinicians "highly citable" manuscripts.
