Several bibliometric indicators have been proposed to evaluate the performance of researchers worldwide, one of them is the h index that takes into account both the number of publications and citations, and ranks researchers according to a scale proposed by Jorge Hirsch in successful researcher (h=20), excellent scientists (h=40) and as a singular individual (h=60). The objective of the study was to evaluate the performance of Paraguayan researchers from the disciplines of medicine, biochemistry and biology through the Hirsch h-Index comparing Google Scholar and Scopus. All Paraguayan researchers from the aforementioned areas whose data were available in Google Scholar and/or Scopus were included. It is a descriptive study with a quantitative approach. For the initial identification of the researchers, the copy available on the CONACYT, Paraguay website was used, and the Publish or Perish software was used. 158 researchers were identified, eight of them are positioned on the Hirsch scale. 13% of researchers had an h index equal to or greater than 10 in Google Scholar and Scopus, with the highest value corresponding to the area of medicine, 54 in Google Scholar and 47 in Scopus. Researchers mostly publish in low-impact national journals with few citations. The performance of the researchers by the h-index is below the region.There is a need for greater investment in national scientific journals for their indexing in databases that collect journals with higher impact.

Objective: Artificial intelligence, as an interdisciplinary field, presents its literature in several areas of knowledge, and its applications offers important contributions for the scientific fields that it dedicates. This study aim is to analyze the scientific production on artificial intelligence in open access scientific articles in the health field and understand its indicators of impact. Methods: It is a descriptive, exploratory and quantitative research, that uses bibliometric and altmetric techniques in complementarity with the aim of ascertaining academic impact through citations data and the on-line attention through the mentions found in the sources of the Social Web. The production data and its metrics were obtained in consultation in Dimensions; and altmetric data retrieved via Altmetric Explorer. Results: In total, 3,121 articles published between 2014 and 2019 were analyzed. The temporal distribution shows increase, with 2019 showing the highest concentration of articles. The academic impact was considered moderate, 70.81% have citation data and, for the visibility, 61.93% presented altmetric data regarding the mentions in the sources of the Social Web. Citations are frequent in old articles and on-line attention is greater for recent publications. Social media as sources with a greater number of mentions, followed by news portals and blogs. Conclusions: It is considered that, by complementing traditional metric studies, such as bibliometrics and citations, altmetrics and its alternative indicators enable a broader understanding of the real impact caused by scientific productions.

Background and Objectives: Latarjet is among the procedures indicated to treat shoulder instability, producing excellent results, including low instability rates and high patient satisfaction. The aim of this study was to report the characteristics of scientific articles that address the subject of the Latarjet procedure through the use of bibliometric analysis. Materials and Methods: Bibliographic searches were performed for original articles published in journals indexed by the Web of Science database until 2021, with no language restrictions. Results: A total of 668 articles published in 87 journals were included. The first publication was in 1981; the most registered publications were in 2018 and 2021 (89 articles), with an annual percentage growth rate of 11.9. Provencher MT was the author with the most published articles, and the institutional affiliation with the most original articles was the Steadman Philippon Research Institute. The most cited article was a study by Burkhart and Beer, and the scientific journal with the most publications on the subject was the Journal of Shoulder and Elbow Surgery. Most published studies included keywords such as dislocation, instability, and meta-analysis. Conclusion: There has been a sustained increase in original articles on the Latarjet procedure. However, the greatest growth in articles has occurred during the last decade, demonstrating the considerable interest among the world scientific community.

Objective: To carry out a scoping review of the meta-analyses published regarding about coronavirus disease 2019 (COVID-19), evaluating their main characteristics, publication trends and methodological quality. Methods: A bibliometric search was performed in PubMed (R), Scopus and Web of Science, focusing on meta-analyses about COVID-2019 disease. Bibliometric and descriptive data for the included articles were extracted and the methodological quality of the included meta-analyses was evaluated using A Measurement Tool to Assess Systematic Reviews. Results: A total of 348 meta-analyses were considered eligible. The first meta-analysis about COVID-19 disease was published on February 26, 2020, and the number of meta-analyses has grown rapidly since then. Most of them were published in infectious disease and virology journals. The greatest number come from China, followed by the United States, Italy and the United Kingdom. On average, these meta-analyses included 23 studies and 15,200 participants. Overall quality was remarkably low, and only 8.9% of them could be considered as of high confidence level. Conclusion: Although well-designed meta-analyses about COVID-19 disease have already been published, the majority are of low quality. Thus, all stakeholders playing a role in COVID-19 deseases, including policy makers, researchers, publishers and journals, should prioritize well-designed meta-analyses, performed only when the background information seem suitable, and discouraging those of low quality or that use suboptimal methods.

Background: Antimicrobial resistance is a serious public health problem that has become a global threat. Special attention should be given to polymyxins (polymyxin B and colistin) which, since their reintroduction into clinical practice, are considered “last resort” drugs. The objective of this study is to perform a bibliometric analysis of scientific research on polymyxin resistance. Methods: Scopus was used to retrieve documents relevant to polymyxin resistance from 2010 to 2019. Data was exported to Microsoft Excel for table presentation. SciVal was used for volume and citation analysis as well as collaboration patterns. Also, we extracted data regarding the top documents, authors, countries, institutions, and the metrics of journals. VantagePoint and VOSviewer were used for geographical distribution of worldwide research and keyword co-occurrence analysis, respectively. Results: A total of 1,409 documents were retrieved. The retrieved documents received 25.0 citations per document. Articles (73.88%) and letters (18.09%) were the most frequent types of documents. During 2010-2019, there was a significant growth in publications (p-value < 0.001). The received citations were 35,209 with a peak in 2016 (11,250 citations). China and the United States led the scientific production with 299 (21.2%) and 238 (16.9%) publications, respectively. Little or no contribution came from central Asia, Sub-Saharan Africa, and Latin America. Chinese institutions have caused the greatest impact, with University of Zhejiang (China) being the most prolific institution on the subject (88 documents). In terms of the most productive journals, Antimicrobial Agents and Chemotherapy ranked first with 196 (13.9%) documents. Most of the documents were published in quartile one journals and only had national collaboration (43.2%). Analysis of keyword co-occurrence revealed that research on polymyxin resistance during the last decade has focused on its relationship with public health, pharmacology, and genetics. Conclusion: The number of documents on polymyxin resistance has increased significantly in the recent years, with a steep growth from 2016 onwards. China and the United States led the scientific production. Most of the documents were published in high-quality journals. Greater joint efforts and more contribution from central Asia, Sub-Saharan Africa, and Latin America are still needed to tackle this global problem.
