At the moment, the academic world is faced with various challenges that negatively impact science integrity. One is hijacked journals, a second, inauthentic website for indexed legitimate journals, managed by cybercriminals. These journals publish any manuscript by charging authors and pose a risk to scientific integrity. This piece compares a journal\'s original and hijacked versions regarding authority in search engines. A list of 16 medical journals, along with their hijacked versions, has been collected. The MOZ Domain Authority has been used to check the authority of both original and hijacked journals, and the results have been discussed. It indicates that hijacked journals are gaining more credibility than original ones. This should alarm academia and highlights a need for serious action against hijacked journals. The related policies should be planned, and tools should be developed to support easy detection of hijacked journals. On the publishers\' side, the visibility of journals\' websites must be enhanced to address this issue.

UNASSIGNED: To perform a bibliometric study to identify and evaluate articles associated with \"orthodontic wires\" indexed in six databases (PubMed, Embase, Cochrane, Scopus, Lilacs, and Google Scholar) from 2010 to 2022.
UNASSIGNED: The search strategy in PubMed combined different medical subject heading terms with free-text words and was adjusted for each selected database. The retrieved documents were original English articles containing the keywords used in the search strategies related to orthodontic wires. Collected data consisted of journal name, nationality, field, JIF-2 and JIF-5, SJR, CiteScore, Q and H-index, and categorization of the study.
UNASSIGNED: In total, 417 articles were retrieved from the initial search. After the exclusion criteria, 257 articles remained. The most common theme was mechanical properties, with basic studies as the main categorization.
UNASSIGNED: This bibliometric survey provides an overview of orthodontic wires publications that might help orthodontists to understand the tendency of the studies on this subject. The retrieved papers were published in 100 journals, including 15 orthodontic journals, mainly in the first and second quartiles. Europe and America were the continents with the highest number of papers. The United States was the country with the highest number of journals on the topic. AJODO presented the highest h-index among the retrieved orthodontic journals. Brazil represented the principal institutions of origin of the listed articles. There was a tendency to increase the number of publications on orthodontic wires over the years. These findings indicate that research on orthodontic wires is still contemporary and relevant.

OBJECTIVE: Trachoma is the cause of blindness or visual impairment in 1.9 million people. Few bibliometric studies have been carried out, but none explore the characteristics of the 100 most cited articles on trachoma.
METHODS: A keyword-based search without time restriction was performed in September 2022 using the Scopus database. Search keywords include the following: \"trachoma; trachome; tracoma; trachomatis.\" Two authors independently screened the literature and extracted data. The search result was obtained to classify the 100 articles according to their number of citations.
RESULTS: The Top 100 articles were published between 1957 and 2015 with a total of 11,102 citations (range 56-689). The country with the most significant contribution was the USA (n = 56). The Lancet was the most active journal (n = 15). Bailey RL was the author with the highest number of publications (n = 30). The Edna McConnell Clark Foundation (n = 26) was the most prominent funding entity. The type of original article was the most published (n = 83), in addition, the most frequent thematic area was prevention (n = 33). The most popular keywords were trachoma (n = 93), chlamydia trachomatis (n = 55), and azithromycin (n = 34).
CONCLUSIONS: The study provides new insight into trachoma research, information that may help healthcare providers, researchers, and stakeholders better understand trends and influential contributions. It highlights under-researched areas that could be the basis for future research.

UNASSIGNED: Explore how the content of the articles published by the Pan American Journal of Public Health during its 100 years of existence has aligned with the key health issues of the Pan American Health Organization (PAHO).
UNASSIGNED: A bibliometric analysis was carried out, with visualization of its results. Information on articles published in the Journal was retrieved from PAHO\'s Institutional Repository for Information Sharing (IRIS) for the first 75 years and Scopus for the last 25 years, until February 2022; References to Governing Bodies documents and statements by the directors were used to establish PAHO\'s key themes.
UNASSIGNED: Initially, 12 573 publications were obtained and 9 289 were considered for analysis for the period 1922 to 1996, and 3 208 for the period 1997 to 2022. For the bibliometric analysis of the Scopus information, indicators such as the authors and their origin, language of publication, and number and origin of citations were considered. For the visualizations, publications were divided into five periods so that they coincided with the periods established for the analysis of PAHO\'s priority themes. Keyword co-occurrence maps were made to observe the evolution of published topics and relate them to public health approaches in each period.
UNASSIGNED: The topics published in the Pan American Journal of Public Health and its precursor bulletins reflect the history of regional public health and its evolution over time, as well as the key health issues of the Pan American Health Organization.
UNASSIGNED: Explorar o alinhamento do conteúdo dos artigos publicados na Revista Pan-Americana de Saúde Pública em seus 100 anos de existência com os principais temas de saúde da Organização Pan-Americana da Saúde (OPAS).
UNASSIGNED: Fez-se uma análise bibliométrica com visualização de seus resultados. Informações sobre os artigos publicados na revista foram recuperadas do Repositório Institucional para o Intercâmbio de Informações (IRIS, na sigla em inglês) da OPAS para os primeiros 75 anos, e da base de dados Scopus para os últimos 25 anos, até fevereiro de 2022. Para estabelecer os principais temas da OPAS, foram usadas referências a documentos dos órgãos diretores e declarações dos diretores.
UNASSIGNED: Inicialmente, foram obtidas 12 573 publicações – 9 289 foram consideradas na análise para o período de 1922 a 1996, e 3 208 para o período de 1997 a 2022. Para a análise bibliométrica das informações da Scopus, foram levados em consideração indicadores como os autores e sua procedência, o idioma das publicações e o número e a procedência das citações. Para as visualizações, as publicações foram divididas em cinco períodos para que coincidissem com os períodos estabelecidos para a análise dos temas prioritários da OPAS. Mapeou-se a co-ocorrência de palavras-chave para observar a evolução dos temas das publicações e para relacioná-los com os enfoques de saúde pública em cada período.
UNASSIGNED: Os temas publicados na Revista Pan-Americana de Saúde Pública e nos boletins que a antecederam refletem o histórico da saúde pública regional e sua evolução ao longo do tempo, bem como os principais temas de saúde da Organização Pan-Americana da Saúde.

Scientific knowledge is being accumulated in the biomedical literature at an unprecedented pace. The most widely used database with biomedicine-related article abstracts, PubMed, currently contains more than 36 million entries. Users performing searches in this database for a subject of interest face thousands of entries (articles) that are difficult to process manually. In this work, we present an interactive tool for automatically digesting large sets of PubMed articles: PMIDigest (PubMed IDs digester). The system allows for classification/sorting of articles according to different criteria, including the type of article and different citation-related figures. It also calculates the distribution of MeSH (medical subject headings) terms for categories of interest, providing in a picture of the themes addressed in the set. These MeSH terms are highlighted in the article abstracts in different colors depending on the category. An interactive representation of the interarticle citation network is also presented in order to easily locate article \"clusters\" related to particular subjects, as well as their corresponding \"hub\" articles. In addition to PubMed articles, the system can also process a set of Scopus or Web of Science entries. In summary, with this system, the user can have a \"bird\'s eye view\" of a large set of articles and their main thematic tendencies and obtain additional information not evident in a plain list of abstracts.

In recent years, the academic world has been faced with much academic misconduct. Examples involve plagiarizing papers, manipulating data, and launching predatory or hijacked journals. The literature exposing these activities is growing exponentially, and so is the presentation of criteria or guidelines for counteracting the problem. Most of the research is focused on predatory or hijacked journal detection and providing suitable warnings. Overlooked in all this is the fact that papers published in these journals are questionable, but nevertheless show up in standard citation databases. We need some way to flag them so future researchers will be aware of their questionable nature and prevent their use in literature review.

OBJECTIVE: To evaluate by the h index the scientific output of researchers from the University of Guadalajara who belong to the Sistema Nacional de Investigadores in the field of Medicine and Health Sciences.
METHODS: Researchers from the University of Guadalajara were selected from the Active SNI Researchers 2013 file. The scientific output of researchers in the fields of Medicine/Health Sciences and Biology/Chemistry was evaluated using the h index estimated by the Scopus website. A sample of capital researchers and Emeritus scientists was taken to perform the same procedure and compare data.
RESULTS: The total number of researchers in the University of Guadalajara who are members of the SNI was 711, of which 67.2 % were level I and in less proportion were level II and III. Only 24.2 % of them were classified in the fields of Medicine/Health Sciences and Biology/Chemistry. The average h index value of researchers level I, II and III in Medicine/Health Sciences field was 5.4, 10.5 and 14.5, respectively. Capital and Emeritus scientists had an average h index of 23.4 and 19.8, respectively.
CONCLUSIONS: The h index measures the quantity and quality of the scientific output and it also avoids bias in the evaluation process. It should be useful for future evaluations of the SNI members and for medical doctors who sign up for the National Academy of Medicine.
Objetivo: evaluar mediante el índice h la productividad científica de investigadores de la Universidad de Guadalajara (UDG) que pertenecen al Sistema Nacional de Investigadores (SNI), en el área de Medicina y Ciencias de la Salud. Métodos: investigadores de la UDG fueron seleccionados del archivo Investigadores Vigentes 2013 del sitio web del SNI. La productividad científica de aquellos registrados en el área de Medicina y Ciencias de la Salud y en Biología y Química se evaluó con el índice h calculado por la base de datos Scopus. Del mismo archivo se seleccionó una muestra de investigadores Eméritos y de aquellos laborando en instituciones capitalinas para realizar el mismo procedimiento y comparar resultados. Resultados: en el SNI, 711 investigadores pertenecieron a la UDG, de los cuales 67.2 % fueron SNI nivel I, y en menor proporción nivel II y III. Solo 24.2 % de ellos, se clasificaron en las áreas de Medicina y Ciencias de la Salud y Biología y Química. El índice h promedio de investigadores nivel I, II y III en Medicina y Ciencias de la Salud fue 5.4, 10.5 y 14.5, respectivamente. Los investigadores capitalinos y Eméritos tuvieron un índice h promedio de 23.4 y 19.8 respectivamente. Conclusión: el índice h permite medir cuantitativa y cualitativamente la productividad científica de los investigadores, evitando sesgo en procesos de evaluación. Se propone su uso en futuras evaluaciones de los miembros del SNI y para médicos que se inscriban a la Academia Nacional de Medicina.

Research ends when the results are shared in the academic and professional community, and for this reason they need to be published in scientific journals of reference. But the question is where should the results of nursing research be published? Taking into account the expanding context and scientific consolidation of the discipline. To answer this question, an analysis will be made of the benefits and the most common criticisms of the two most important multidisciplinary literature data bases, as well as examining the context of the Spanish nursing journals in these data bases. A description will also be made of the indexing systems, as well as making proposals to contribute to improved visibility of Spanish nursing research through the positioning of its journals.
