ABSTRACT
Abstract Background Perinatal depression (PND) is a clinical disease developed in any stage during the pregnancy and postpartum period with serious health and economic implications. Objective The aim of this work was to analyze via bibliometrics indicators Mexico's production on PND to provide a view of the academic landscape and a comprehensive reference for subsequent research in the country. Method The Scopus and Web of Science (WoS) databases were used to perform a search for peer reviewed papers related to PND in México. The search was made following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The extracted data were processed with VOS Viewer to examine link strength and clusters associations of diverse bibliometrics variables. Results A total of 132 records were retrieved and we included 70 studies in the bibliometric analysis after application of the exclusion criteria. The authors with more papers were Navarrete L., and Asunción Lara M. The institutions with more papers were the National Institute of Perinatology, Ramón de la Fuente National Institute of Psychiatry, and National Institute of Public Health of Mexico. A diminution of the research considered in PND is observed in the last two years. Four keyword clusters were identified related to PND: symptoms, prevalence, pregnancy. Discussion and conclusion The scarce literature concerning PND in Mexico compared with other countries could be due the limited collaboration between the health institutes. An urgent need to increase research on PND in Mexico is evident to be applicable in the management of resources in the healthcare system.

Objetivo El objetivo de este trabajo fue analizar a través de indicadores bibliométricos la producción de México sobre PND, para brindar una visión del panorama académico y un referente integral para investigaciones posteriores en el país. Método Se utilizaron las bases de datos Scopus y Web of Science (WoS) para realizar una búsqueda de artículos revisados por pares relacionados con la PND en México. La búsqueda se realizó siguiendo los elementos de informes preferidos para revisiones sistemáticas y metaanálisis (PRISMA). Los datos extraídos se procesaron con VOS Viewer para examinar la fuerza de los enlaces y las asociaciones de grupos de diversas variables bibliométricas. Resultados Se recuperaron un total de 132 registros y se incluyeron 70 estudios en el análisis bibliométrico después de la aplicación de los criterios de exclusión. Los autores con más artículos fueron Navarrete L. y Asunción Lara M. Las instituciones con más artículos fueron el Instituto Nacional de Perinatología, el Instituto Nacional de Psiquiatría Ramón de la Fuente y el Instituto Nacional de Salud Pública de México. Se observa una disminución de las investigaciones consideradas en el PND en los últimos dos años. Se identificaron cuatro grupos de palabras clave relacionadas con la PND: síntomas, prevalencia y embarazo. Discusión y conclusión La escasa literatura sobre PND en México en comparación con otros países podría deberse a la limitada colaboración entre los institutos de salud.

ABSTRACT
Objective@#To evaluate the clinical efficacy of invisible orthodontic appliances without brackets for the distal movement of maxillary molars to improve the ability of orthodontists to predict treatment outcomes.@*Methods@#Web of Science, Cochrane Library, Embase, PubMed, Wanfang Database, CNKI Database, and VIP Database were searched for studies investigating the efficacy of invisible orthodontic appliances for distal movement of maxillary molars in adult patients and published from database inception to August 1, 2023. A total of three researchers screened the studies and evaluated their quality and conducted a meta-analysis of those that met quality standards.@*Results@#This study included 13 pre- and postcontrol trials with a total sample size of 281 patients. The meta-analysis revealed no significant differences in the sagittal or vertical parameters of the jawbone after treatment when compared with those before treatment (P>0.05). The displacement of the first molar was MD=-2.34, 95% CI (-2.83, -1.85); the displacement was MD=-0.95, 95% CI (-1.34, -0.56); and the inclination was MD=-2.51, 95% CI (-3.56, -1.46). There was a statistically significant difference in the change in sagittal, vertical, and axial tilt of the first molar before and after treatment. After treatment, the average adduction distance of the incisors was MD=-0.82, 95% CI (-1.54, -0.09), and the decrease in lip inclination was MD=-1.61, 95% CI (-2.86, -0.36); these values were significantly different from those before treatment (P<0.05).@*Conclusion@#Invisible orthodontic appliances can effectively move the upper molars in a distal direction and control the vertical position of the molars. When the molars move further away, there is some degree of compression and distal tilt movement, which is beneficial for patients with high angles. The sagittal movement of incisors is beneficial for improving the patient's profile.

ABSTRACT
Background: South Africa reported a new variant of SARS-CoV-2, named 'Omicron,' to the World Health Or-ganization on November 24, 2021. Scientometric analysis quantify all currently available written communica-tion, the authors of that communication, and their citation analysis. The study's goal was to use the Scopus and Web of Science databases to look at the research metrics of Omicron publications published between Jan-uary 1965 and March 2020. Methods:All scientific research outputs with the word 'Omicron' in the title were retrieved from the Web of Science (January 1965 to March 2022) and Scopus (January 1896 to March 2022) databases on April 10, 2022. The data was analyzed based on year-wise publications; leading authors; predominant journals in publishing, highly cited articles with citations; type of publications; subject classification, frequently used keywords, geo-graphical distribution of publication, language, and more contributed institutions. Results: There were 1229 research outputs for WoS and 655 from Scopus. The number of publications for WoS increased from 22 in 1965 to 265 in 2022, while Scopus increased from 1 in 1896 to 356 in 2022. Both the databases identified the author Yuen KY as the highest contributor; Journal of Virology and Nature as the predominant journals; the Lancet as highly cited journal; majority as original articles; frequently used key-words as 'SARS-CoV-2'; the United States of America as the most productive country; majority publication in English. The publications were mainly on the subjects Chemistry and Medicine by WoS and Scopus, respec-tively. The most productive institute was the ‘University of California Systems’ by WoS and the ‘University of Hong Kong’ by Scopus. Conclusion: The term 'Omicron' first appeared in the domain of Chemistry in the late 18th century. The growth pattern of publication was not consistent. The above research metrics will be helpful to researchers in the coming days.

ABSTRACT
In recent years, the incidence of adenocarcinoma of esophagogastric junction (AEG) has increased gradually. Due to the unique anatomical location and the different biological features from esophageal cancer and gastric cancer, AEG cannot be simply equated with esophageal cancer or gastric cancer, and the definition, classification and treatment methods of AEG are still controversial. As a result, the study of AEG is becoming increasingly important. Using bibliometrics, the authors search English literatures from the Web of Science Core Collection database from the establishment to December 31, 2022, with the keyword adenocarcinoma of esophagogastric junc-tion. To systematically review the international literatures on AEG, EndNote and Excel are used to manage literatures and perform statistical analysis, and VOSviewer and CiteSpace are used to analyze the social network, time series of countries, institutions, authors and keywords, the co-citation of authors and the citation bursts of keywords. The authors summarize the research status and hot trends in this field, hoping to provide reference for future research.
ABSTRACT
@#Objective To explore the hotspots and trend of research on the signaling pathways of intracerebral hemorrhage in the past 10 years through bibliometrics and visual analysis. Methods We used CiteSpace to perform bibliometrics and visual analysis on relevant articles published in the recent 10 years, which were obtained from the Science Citation Index Expanded database of the Web of Science Core Collection. Results According to visual analysis of 796 pieces of literature on intracerebral hemorrhage-related signaling pathways, there is a growing number of papers published in this field. China was the country with the largest number of papers published. Loma Linda University was the institution with the largest number of papers published. The funding institution sponsoring most in this field was the National Natural Science Foundation of China. The keyword analysis showed that the research focused on inflammatory reactions, oxidative stress, microRNA gene expression, nuclear factor-kappa B signaling pathways, extracellular regulated protein kinase 1/2 signaling pathways, the lipid-signaling molecule sphingosine-1-phosphate, and scalp acupuncture therapy. Conclusion CiteSpace-based visual analysis can directly display the research hotspots and trend of intracerebral hemorrhage-related signaling pathways, providing new insights into the treatment and prevention of intracerebral hemorrhage.
ABSTRACT
OBJECTIVES@#To realize the dynamic visualization of forensic odontology based on the bibliometrics methods, and capture the research hotspots and identify the future development trend.@*METHODS@#Literature articles published from January 1995 to December 2020 were searched according to specific subject words in the core data set of Web of Science. The visualization analysis of publishing country, institution, discipline, author, co-cited journal and keywords was performed by CiteSpace 5.7.R5W software.@*RESULTS@#The annual analysis of publications showed an upward trend of forensic odontology research literature year by year, with the number of annual publications more than 110 in the last five years. Developed countries were the main source of contributions and the average centrality was greater than 0.2. The research of forensic odontology involved multiple disciplines, including stomatology, biology, computer science and medical imaging, with a distinct interdisciplinary feature. A total of 115 nodes were obtained by keyword cluster analysis. The principal line of forensic odontology mainly included individual identification and age estimation and the emergence of hotspots was closely related to new technologies. Population-based odontology investigation, improvement of traditional dental age estimation method and dental age estimation based on new technology were popular research in forensic odontology.@*CONCLUSIONS@#Developing countries urgently need to increase the focus on related research.

OBJECTIVE To analyze the current status, hotspots and development trends of research on the treatment of non-alcoholic fatty liver disease (NAFLD), providing reference for subsequent research. METHODS Searching the Web of Science database, the literature related to the treatment of NAFLD from the establishment of the database to December 31, 2022 were collected. CiteSpace 6.1.R6 was used to construct a visual atlas, perform collaborative network analysis on authors, countries and institutions, and conduct keyword co-occurrence, clustering and emergence analysis to explore its research status and hotspots. RESULTS A total of 3 882 articles were included, and the number of publications had been increasing year by year. The top three countries in terms of publication volume were China, the United States, and Japan. The author with the highest volume of publications was Sanyal from the United States (37 articles), while the institution with the highest volume of publications was the University of California, San Diego (75 articles). A closely connected research team abroad mainly conducted large-scale randomized controlled trials (RCT) to evaluate the effectiveness and safety of various interventions, including medication and lifestyle, in treating NAFLD. However, domestic researches mainly focused on basic researches about the treatment of NAFLD with effective medicinal ingredients, and were characterized by traditional Chinese medicine. There were relatively few high-quality large-scale RCT studies related to it. Keyword analysis showed that researches in various countries mainly focused on regulating liver oxidative stress and inflammation, improving the overall balance of glucose and lipid metabolism. Except for hypoglycemic drugs, drugs that act on various comprehensive metabolic homeostasis targets in the body had entered clinical research, and had enormous therapeutic potential. CONCLUSIONS The research on NAFLD treatment continues to grow in popularity and tends to research targets and drugs for regulating systemic metabolic homeostasis. As the main force of research, China should strengthen communication with the international community, grasp the trends and directions of basic research, attach importance to clinical research, and continuously tap the therapeutic potential of traditional Chinese medicine.

Introduction In the last decades, the incidence and prevalence of urinary incontinence have been increasing. There are many publications about this subject, there are new devices, and the treatment of this condition has changed with time. The objective of the present study was to perform a bibliometric analysis of the publications about male urinary incontinence in the indexed journals. Methods We performed a retrospective descriptive bibliometric analysis of the medical literature available on the Web of Science (WOS) database about male urinary incontinence between 2002 and 2020. Through the WOS database, the variables to be analyzed were obtained, and tables and graphs were created using the Microsoft Office Excel 2017. Results We found 498 publications in 88 journals. Since 2006, there has been an exponential growth in publications. The 3 journals with the highest percentage of publications were: J Urol, with 25.1% (125), Neurol Urodyn, with 16.5% (82), European Urology Journal, with 11.4% (57); only 5 of the 20 journals with the highest number of publications had an impact factor ≥ 3. The country with the highest percentage of publications was the United States with 21,2% (105), followed by European countries. In Latin America, the country with the highest number of publications was Brazil, with 2,6% (13). No Colombian studies were found with this specific research. Conclusion The present is the first bibliometric analysis on male urinary incontinence. Over time, publications on this topic have increased, and most of them are concentrated in journals from the United States and Europe. The publication in journals with a high impact factor is not predominant, and the number of publications from Colombia and other Latin American countries is very low.

Resumen Introducción: La disciplina científica de la bioinformática tiene el potencial de generar aplicaciones innovadoras para las sociedades humanas. Costa Rica, pequeña en tamaño y población en comparación con otros países de América Latina, ha ido adoptando la disciplina de manera progresiva. El reconocer los avances permite determinar hacia dónde puede dirigirse el país en este campo, así como su contribución a la región latinoamericana. Objetivo: En este manuscrito se reporta evidencia de la evolución de la bioinformática en Costa Rica, para identificar debilidades y fortalezas que permitan definir acciones a futuro. Métodos: Se realizaron búsquedas en bases de datos de publicaciones científicas y repositorios de secuencias, así como información de actividades de capacitación, redes, infraestructura, páginas web y fuentes de financiamiento. Resultados: Se observan avances importantes desde el 2010, incluyendo un aumento en oportunidades de entrenamiento y número de publicaciones, aportes significativos a las bases de datos de secuencias y conexiones por medio de redes. Sin embargo, ciertas áreas, como la masa crítica y la financiación requieren más desarrollo. La comunidad científica y sus patrocinadores deben promover la investigación basada en bioinformática, invertir en la formación de estudiantes de posgrado, aumentar la formación de profesionales, crear oportunidades laborales para carreras en bioinformática y promover colaboraciones internacionales a través de redes. Conclusiones: Se sugiere que para experimentar los beneficios de las aplicaciones de la bioinformática se deben fortalecer tres aspectos clave: la comunidad científica, la infraestructura de investigación y las oportunidades de financiamiento. El impacto de tal inversión sería el desarrollo de proyectos ambiciosos pero factibles y colaboraciones extendidas dentro de la región latinoamericana. Esto permitiría realizar contribuciones significativas para abordar los desafíos globales y la aplicación de nuevos enfoques de investigación, innovación y transferencia de conocimiento para el desarrollo de la economía, dentro de un marco de ética de la investigación.
Abstract Introduction: The scientific discipline of bioinformatics has the potential to generate innovative applications for human societies. Costa Rica, small in size and population compared to other Latin American countries, has been progressively adopting the discipline. Recognizing progress makes it possible to determine where the country can go in this field, as well as its contribution to the Latin American region. Objective: This manuscript reports evidence of the evolution of bioinformatics in Costa Rica, to identify weaknesses and strengths allowing future actions plans. Methods: We searched databases of scientific publications and sequence repositories, as well as information on training activities, networks, infrastructure, web pages and funding sources. Results: Important advances have been observed since 2010, such as increases in training opportunities and the number of publications, significant contributions to the sequence databases and connections through networks. However, areas such as critical mass and financing require further development. The scientific community and its sponsors should promote bioinformatics-based research, invest in graduate student training, increase professional training, create career opportunities in bioinformatics, and promote international collaborations through networks. Conclusions: It is suggested that in order to experience the benefits of bioinformatics applications, three key aspects must be strengthened: the scientific community, the research infrastructure, and funding opportunities. The impact of such investment would be the development of ambitious but feasible projects and extended collaborations within the Latin American region and abroad. This would allow significant contributions to address global challenges and the implementation of new approaches to research, innovation and knowledge transfer for the development of the economy, within an ethics of research framework.

Objective To analyze the forensic science-related literature included in the Web of Science database in the recent decade through bibliometric methods, to provide reference for relevant research. Methods Literatures were searched in 3 ways: Subject search, Journal search and Institution search. The annual distribution, national (regional) distribution, institution distribution, journal distribution and the research hotspots of the related literatures were analyzed through Thomson Data Analyzer (TDA), Ucinet, VOSviewer, and so on. Results A total of 49 469 related literatures were included in the recent decade. The number of literatures continued to climb year by year. The top 15 countries (regions) accounted for 78.52% of the total number of published literatures, and China ranked 5th, but ranked 12th in terms of the proportion of high-cited papers; Netherlands, Switzerland, Australia, etc. had high comprehensive influence. The number of countries (regions) that cooperated with China were 129, including the United States, the United Kingdom and Germany. The Institute of Forensic Science of Saint Mary's University, University of Sydney and Netherlands Forensic Institute had high comprehensive influence, and the related literatures were published on 6 357 journals. According to high-frequency co-occurrence network and high-cited papers, brain injury, health policy, assessment scales and models and medical imaging were selected as research hotspots. Conclusion The total number of literatures in forensic science included in international SCI increased significantly, and the influence of China's achievements needs to be greatly enhanced; the research institutions were scattered, and China's research power needs to be continuously condensed; the research hotspots in international fields are extensive, and the international participation of China in top level research needs to be strengthened.
