       INTRODUCTION: Gender disparities in academic productivity remain well described. Although women have historically been underrepresented in cardiothoracic surgery, longitudinal trends in authorship are not fully understood. We aimed to evaluate temporal patterns in women's representation as first and senior authors in major cardiothoracic surgery journals.
    METHODS: A bibliometric analysis of 4 cardiothoracic surgery journals, Annals of Thoracic Surgery, the Journal of Thoracic and Cardiovascular Surgery, the European Journal of Cardio-Thoracic Surgery, and Journal of Thoracic and Cardiovascular Surgery Open, was conducted of all PubMed-indexed articles published between 2002 and 2022. Author data were extracted using BioPython, and gender was assigned by first name using GenderAPI. Only assignments with ≥90% confidence were included. Linear regression assessed trends in women's first and senior authorship over time, and global patterns were visualized using R (R Core Team, 2023; The R Foundation for Statistical Computing, Vienna, Austria) using RStudio version 2024.04.2+764 (Posit Software, Boston, MA).
    RESULTS: Of 53,034 publications, 38,091 (71.8%) had gender identified for both first and senior authors and were included in the analysis. A significant association was observed between first and senior author gender (P < 0.001), with most articles authored by men in both positions (82.0%), while only 2.8% had women as both first and senior authors. In the contemporary cohort (2020-2022), this proportion increased to 5.2%. Trends varied by journal, with projected increases in the women-to-men authorship ratio by 2030, highest in Annals of Thoracic Surgery. Globally, Northern European countries demonstrated the greatest representation of women first authors.
    CONCLUSIONS: Although gender disparities persist, women's authorship in cardiothoracic surgery journals is increasing. Journal-specific and regional differences in representation, considered alongside imperfect workforce benchmarks, highlight areas warranting continued attention.

    Bibliometric Analysis of the Top 100 Most Cited Publications from Saudi Arabia Reveals the Predominance of Medical Fields.
    Mahmoud Kandeel, Abdulla Al-Taher.
       Objectives: To explore the citation impact, journals, international collaborations, trends of research topics and gain more visibility for the Saudi contribution to the global scientific landscape.
    Methods: This bibliometric study analyzes the top 100 cited publications affiliated with Saudi Arabia in Scopus, from inception to January 2026. The extracted bibliometric indicators include total citation metrics, sources, collaboration maps, and co-occurrence networks of keywords and collaborations.
    Results: The results indicate a strong predominance for medicine and health sciences as the subjects of the most prolific and significant number of citations. A substantial proportion of the most cited papers originates from major global health projects, in particular the Global Burden of Disease (GBD) consortium, which focuses on mortality, morbidity, and epidemiological metrics. Clinical and public health fields are highly represented, including obesity and cardiovascular risk, disease burden, and population health metrics. The most frequent journals include the leading medical journals in the field, namely The Lancet, Nature, Science and the New England Journal of Medicine. Keyword analysis confirms the dominance of medical themes; the most prominent keywords included epidemiology, risk factors, and global health indicators. Within the biomedical predominance, bioinformatics tools such as MEGA software contribute to the citation impact.
    Conclusions: Saudi Arabia's citation impact is predominantly driven by international consortia participation and bioinformatics tool development, highlighting the opportunities for strengthening independent and nationally led research programs of global significance.

    Characterizing Core Journals in Ophthalmology Literature Using Bradford's Law: A Bibliometric Analysis.
    Leo Meller, Vasan Jagadeesh, Michael Oca, Katherine Wilson, Jeffrey Lee, Sally Baxter, Nathan Scott.
       Purpose: The exponential growth of ophthalmology research can be challenging to keep up with for trainees, researchers and clinicians and little has been done to identify core ophthalmology journals. We thus applied Bradford's law to characterize core journals in ophthalmology.
    Design: Cross-sectional bibliometric analysis.
    Methods: Two sets of top 10 National Library of Medicine indexed ophthalmology journals based on h-index and impact factor (IF) were combined to create top 14 journals used for analysis. The references from all articles published in these journals in one randomized quarter were compiled into a citation database. Bradford's law was applied to identify zonal distribution of journals.
    Results: A total of 3093 journals containing 34,633 articles were cited in ophthalmology literature from July-Sept 2022. Under linear regression, IF was significantly associated with h-index for the top 20 journals (P < 0.001) and top 10 ophthalmology journals (P = 0.017). H-index was significantly associated with number of citations for top 10 ophthalmology journals (P < 0.001). Three zones obeying Bradford's law were identified, with zone 1 (core) containing six journals and 8410 citations, zone 2 containing 27 journals and 8359 citations, zone 3 containing 154 journals and 8419 citations. A linear relationship between the log journal rank for zones 1-3 and cumulative number of citations was found (R2 = 0.996), validating Bradford's law.
    Conclusions: Six core ophthalmology journals were identified: American Journal of Ophthalmology, Investigative Ophthalmology & Visual Science, Ophthalmology, JAMA Ophthalmology, British Journal of Ophthalmology, Journal of Cataract & Refractive Surgery. These highly cited core journals may serve as high-yield resources for describing the latest advances in ophthalmology research and may guide ophthalmology trainees and educators with their learning and teaching.

    From congress to journal: publication outcomes of oral scientific presentations at the European society of urogenital radiology congresses.
    Hamza Eren Güzel, Özgür Yaşar, Babak Saravi.
       Background/Objectives: Publication of congress presentations as full-text articles is an indirect indicator of scientific productivity and research quality. This study evaluated publication outcomes of oral scientific presentations delivered at European Society of Urogenital Radiology (ESUR) congresses and descriptively explored variation according to presentation characteristics.
    Methods: This retrospective bibliometric study included oral scientific presentations delivered at ESUR congresses between 2017 and 2022, excluding the canceled 2020 meeting. Poster presentations, invited lectures, educational sessions, and non-scientific sessions were excluded to maintain consistency with recent radiology congress publication studies. Presentations already published as full-text articles before the corresponding congress were excluded from the subsequent-publication denominator and reported separately. Publication status was determined by systematic PubMed/MEDLINE searches. The primary outcome was subsequent publication as a PubMed/MEDLINE-indexed full-text original research article by the final search date.
    Results: Among 183 oral presentations, 22 had been published before the corresponding congress and two were classified as ambiguous congress-month publications. After exclusion of pre-congress publications, 161 presentations were eligible for the main subsequent-publication analysis. During full available follow-up, 79 presentations were subsequently published, corresponding to a publication proportion of 49.1% (95% CI, 41.1-57.0%). The median time to publication was 12.9 months, and 69 of 79 subsequent publications (87.3%) appeared within 36 months.
    Conclusions: ESUR oral scientific presentations showed a subsequent publication proportion comparable to contemporary European radiology congresses. The use of oral-only inclusion, exclusion of pre-congress publications, and PubMed/MEDLINE-based publication matching aligns this study with recent ECR, ESGAR, and ESNR publication-outcome analyses.

    Retraction of Dentally Related Articles (2004-2025): A descriptive study assessing the impact on oral hygiene and caries management literature.
    R Constance Wiener, Ruchi Bhandari.
      Purpose The purpose of this study was to evaluate the potential impact on science of post-retraction citations in oral hygiene and caries management literature by examining the characteristics of retracted dental articles.Methods The Retraction Watch Database was the data source used for the descriptive study. The database features lists and reports that identify retracted manuscripts. Retractions were characterized by author, year, location, and reason for the retraction. Articles pertaining to oral hygiene and caries management were retrieved, read, and evaluated according to the following criteria: 1) Presented a potential neutral or minimal impact (the citing article cited general background information from the retraction which was not inaccurate nor based on the results of the retracted manuscript); 2) Presented a potential major negative impact on influencing science (the citing article cited inaccurate information or information based on the retracted article); 3) Unable to determine (behind a paywall, in a study without dates of publication, or otherwise unavailable); or 4) Included a notation that the citation was from a retracted article.Results Of the 64,739 retractions listed in the database, there were 297 dentally related retracted publications (0.46% of all retractions and 0.017% of all dentally related articles published from 2004-2025). Twenty-eight retracted articles addressed oral hygiene and caries management. The 28 articles were cited in a total of 1179 articles with 347 post-retractions. Seventy-four post-retraction citations had a potentially major negative scientific impact, 106 had a potential minor impact, 6 had a notation that the reference being used had been retracted, and the remainder were unable to be evaluated.Conclusion There were relatively few dentally related retractions as a percentage of the total number of publications. However, authors who used retracted articles as citations created a potential negative impact on the presentation and sharing of dental research, specifically in oral hygiene and caries management research.

    A longitudinal analysis of gendered career trajectories and academic efficiency in North American MD/PhD faculty.
    Stephanie Quon, Marissa Joseph, Faisal Khosa.
      Gender disparities in academic medicine persist despite increasing women's representation in higher education. Prior research highlights the underrepresentation of women in senior ranks and leadership roles, yet few studies have assessed these disparities using time-adjusted productivity metrics. This study aims to evaluate gender-based differences in academic rank, scholarly productivity, and leadership representation among MD/PhD faculty in North America, accounting for career length and institutional variability. A secondary analysis was conducted on a dataset of 6,149 MD/PhD faculty from 122 accredited North American medical schools. Time-adjusted measures of productivity, H-index per year and citations per year, were calculated. Gender differences in rank, productivity, and leadership were assessed using Mann-Whitney U tests and descriptive statistics. Institutional-level representation of women in leadership roles was also analyzed. Women held significantly lower academic ranks than males and were underrepresented in departmental leadership roles. Despite achieving assistant and full professorships earlier, women were overall less likely to reach these positions. Males exhibited higher time-adjusted H-index and citation rates (p < .0001), with a compounded 3.5-year publication gap. Institutional analysis revealed stark variability: 38 institutions had no women in MD/PhD leadership roles, while fewer than 20 percent achieved gender parity. Gender disparities in academic medicine cannot be explained by productivity alone. Structural barriers, opaque promotion criteria, and institutional cultures continue to impede women's advancement and leadership. Addressing these inequities requires transparent policies, targeted mentorship, equity audits, and inclusive leadership pathways to support a more equitable academic workforce.

    Cross-race vs. same-race collaboration in plastic surgery: AI-driven analysis of research and race-interaction dynamics.
    Georgios Karamitros, Heather J Furnas, Gregory A Lamaris, Michael P Grant, Sofoklis Goulas.
       Background: Racial diversity in plastic surgery research remains a challenge. This study employs artificial intelligence (AI)-driven big data analysis to assess racial representation, cross-race mentorship trends, and research productivity disparities among plastic surgery authors over 12 years (2010-2022).
    Methods: A retrospective, cross-sectional study was conducted using AI-based web scraping to extract authorship data from 24 PubMed-indexed plastic surgery journals. RaceAPI, a machine-learning-based name-classification tool trained on U.S. Census data, inferred racial identity. Chi-square tests were used to evaluate racial disparities in first and senior authorship, mentorship patterns, and research output.
    Results: Among 16 019 publications, White researchers remained the dominant group among first authors (70% in 2010 vs. 66.2% in 2022, P < 0.001) and senior authors (73.8% vs. 72.6%, P < 0.01). Black first and senior authorship declined (8.1% to 6.4%, P < 0.001; 9.2% to 6.1%, P < 0.001), while Asian representation increased (first: 16% to 18.8%, P = 0.027; senior: 11.7% to 16%, P < 0.001). White authors had significantly higher research productivity (2.15 papers per author) than Asian (1.97), Black (1.76), and Hispanic (1.68) researchers (P < 0.05). Black senior authors had the highest rate of cross-race mentorship (77.5%), while White (26.8%) and Asian (27.3%) senior authors exhibited strong same-race mentorship preferences.
    Conclusions: Persistent racial disparities in authorship and research participation among racial groups that are persistently underrepresented in medical school and plastic surgery residencies suggest the need to assess and address educational barriers prior to medical school. Strengthening mentorship networks and increasing access to research for minority trainees could foster a thriving plastic surgery workforce for all communities, including those currently underserved.
    Level of Evidence: Level III, cross-sectional study.

    Mohammed Nawaiseh, Qais Nawaiseh, Meryem Hamam, Rachid Kaddoura, Ariel Sacknovitz, Aarti Kishore Jain, Nimrod Gozum, Yara Nawaiseh, Rund Haddadin, Ghada Elhawary, Mohamed Elfil, Gurmeen Kaur, Priyank Khandelwal, Chirag Gandhi, Vincent Q Sier, Fawaz Al-Mufti.
       INTRODUCTION: This study conducts a comprehensive bibliometric analysis of global stroke mortality research, by assessing publication trends, top authors, institutions, countries, and thematic analysis of keywords.
    METHODS: We performed a bibliometric analysis using Web of Science data retrieved on December 21, 2024, based on title searches for "Stroke mortality," "CVA mortality," "Cerebral infarction mortality," and "Cerebrovascular accident mortality." We generated descriptive statistics, investigated publication and citation trends, and performed advanced mappings for keyword frequency and thematic evolution.
    RESULTS: Of 2,261 stroke mortality documents from 636 journals (1961-2024), the annual growth was 1.73%. Each document averaged 37.7 citations, with 46,494 total references. This study included 14,456 authors (48 single-authored) and averaged 8.89 coauthors per document; 21.32% involved international collaboration. Publication output increased markedly post-2000, peaking with 1,171 studies in 2017-2024. Stroke (246 articles) was the most productive journal followed by Journal of Stroke & Cerebrovascular Diseases (137); the USA (2,975 articles) and China (2,536) dominated global output. Wang Y led as the most prolific author (77 articles), and Capital Medical University in China produced the highest number of publications (143). Collaboration networks featured strong multinational clusters led by the USA, China, and key European nations.
    CONCLUSION: This bibliometric analysis showed a steady but modest research growth, with the USA and China leading in output and citation. Thematic shifts revealed movement from clinical risk factors to public health and biological predictors. While strong international collaborations exist, regional partnerships remain limited in areas like Africa and Latin America.

    Tanveer Rehman, Srijeeta Mitra, Shubhankar Dubey, Dinesh Kumar, Jaya Singh Kshatri, Banambar Sahoo, Sanghamitra Pati.
       BACKGROUND: Understanding Jharkhand's healthcare landscape is crucial for devising targeted interventions and strengthening research efforts to address the pressing healthcare needs of the state.
    OBJECTIVE: The objective of this study was to carried out a bibliometric analysis of original research articles conducted in Jharkhand between 2013 and 2023 to assess the state of health research.
    MATERIALS AND METHODS: A systematic search across Medline, Embase, CINAHL, and Cochrane databases identified 6492 articles, which were screened using Covidence software after duplicate removal. Descriptive analyses using Microsoft Excel 2019 and bibliometric networks with VOSviewer software were employed.
    RESULTS: Among 209 identified articles, 58% belonged to the Global Burden of Disease category 1 topics. Half of the studies utilized cross-sectional study designs and were conducted in facility-based settings with 22% exclusively focused on the tribal population. The average annual publications, number of citations, and number of authors per article were 19 articles, 12, and 6, respectively, with publication peaks in 2015 and 2020. Government-affiliated corresponding authors constituted 46% of all articles, with 21% from international institutes. Ethical approval was reported in 86% of articles, and 71% of funding originated from international sources. The Central Institute of Psychiatry, Ranchi, emerged as the most productive institute while leading journals were the Asian Journal of Psychiatry and PLOS One.
    CONCLUSION: Enhancing the focus on interventional research, fostering local partnerships and international collaborations, and addressing the health needs of marginalized communities can lead to more effective healthcare interventions and equitable health outcomes in Jharkhand.

    Retractions of publications on central nervous system tumors based on the Retraction Watch Database.
    Xiaoyan Gao, Renjie Mao, Fa Lin, Jing Shang, Jingjing Wu, Lu Chen, Hao Wang.
       BACKGROUND: Retraction serves as a critical mechanism for correcting flawed publications and preserving the integrity of the scientific literature. Systematic analysis focused on retractions in Central Nervous System (CNS) tumor research is still lacking. This study characterized retracted CNS tumor publications regarding temporal trends, geographic distribution, retraction reasons, citation patterns, and retraction lag.
    METHODOLOGY: Retraction data were downloaded from the Crossref/Retraction Watch Database on December 31, 2025. CNS tumor‑related retractions were identified using tumor terms derived from the 2021 WHO Classification of Tumors of the Central Nervous System. Eligible records were screened manually, and tumor type, article type, retraction reason, first-author country, author count and time to retraction were extracted. Citation data were retrieved from Web of Science, and journal impact factor (JIF) and quartile were obtained from the 2024 Journal Citation Reports. Descriptive statistics, the Mann-Kendall test and Kruskal‑Wallis test were used.
    RESULTS: 582 CNS tumor articles were included. CNS tumor retractions increased over time and peaked in 2023. "Gliomas, glioneuronal tumors, and neuronal tumors" accounted for 74.57% (434/582). 80.58% (469/582) were retracted due to misconduct. In terms of absolute numbers, China was the leading first‑author country, followed by USA and India. Basic research accounted for 75.26% (438/582). The median time to retraction was 805.5 days (IQR: 423.25-1,711 days). A total of 515 articles received at least one citation (total citations 12,151), and 89.71% (462/515) had citation after retraction. The median pre‑retraction, post‑retraction, and total citations were 5 (IQR: 1-17), 3 (IQR: 1-7), and 10 (IQR: 3-24), respectively. Significant differences were observed in normalized citation counts and retraction lag across most retraction reason categories, JIF and quartiles, article types, author counts, and first‑author countries.
    CONCLUSIONS: CNS tumor retractions have increased markedly as the primary driver. The persistent post-retraction citation of flawed research highlights a critical gap threatening evidence-based neuro-oncology.

    Gender disparities across editorial roles in radiology journals; A cross-sectional analysis.
    Yakup Ozbay, Aynur Turan, Selma Uysal Ramadan.
       PURPOSE: Gender disparities persist in academic radiology, particularly in leadership roles. However, gender representation across radiology journal editorial boards has not been comprehensively evaluated. This study evaluated gender representation across editorial roles in radiology journals and to identify the factors associated with gender disparity.
    METHODS: In this cross-sectional retrospective study, radiology journals listed in the Web of Science Core Collection were screened between November 2025 and February 2026. Editors were categorized by role, and gender was determined using publicly available information. Journal characteristics, including indexing status, quartile, geographic origin, subspecialty, publishing model, impact factor, and publication duration were recorded. Gender distributions were compared using chi-square tests. Factors associated with gender disparity were evaluated using logistic regression.
    RESULTS: A total of 166 journals comprising 9506 editors were included. Women were underrepresented across all editorial roles, accounting for 21.0% of editors-in-chief and 26.6% of editorial board members. Female representation differed significantly according to journal characteristics (all p < 0.05). In multivariable analysis, emerging sources citation indexing (OR:0.14; 95% CI, 0.04-0.48, p = 0.002), society-association journal status (OR:0.27; 95% CI, 0.10-0.74, p = 0.011), and longer publication duration (OR:0.30; 95% CI, 0.10-0.89, p = 0.031) were associated with lower odds of gender disparity. Absence of a female editor-in-chief was independently associated with higher odds of gender disparity (OR:4.66; 95% CI, 1.87-11.63, p = 0.001).
    CONCLUSION: Women remain underrepresented in editorial roles in radiology journals, with variation associated with journal characteristics and leadership composition.

    Exploring Translational Medical Research Progress in G20 Countries: 5-Year Study.
    Hana A Alhumud, Fars K Alanazi, Edward B DeVol.
       Objectives: Biomedical research is crucial for advancing medical knowledge and improving public health. However, the research process is often disjointed and lacks seamless progression, leading to delays and missed opportunities. To address this, the concept of translational research has emerged, focusing on the smooth transition of research results to the next stage of inquiry.
    Methods: This study analyzed approximately 40,000 research publications from the Web of Science database to identify research activities associated with translational research. Publications from Group of 20 (G20) countries over the past 5 years were examined to explore patterns of research focus and progress in this field.
    Results: There is no universal formula for successful translational research across G20 countries. What works in one country may not yield the same results in another, as factors contributing to success vary significantly among nations. Each country's unique history of success and failure influences its translational research outcomes.
    Conclusion: The study highlights the importance of collaboration and global research efforts in improving predictability and outcomes in translational research. By drawing on diverse perspectives and experiences, the potential for success in specific research activities is expected to increase. Overall, the study emphasizes the need for a more connected and coordinated approach to biomedical research to enhance its impact on health improvement.

    Retractions in Psychology and Psychiatry in Web of Science : A Bioethical Perspective.
    Oriana Arellano-Faúndez, Chiara Saracini, Maria T Muñoz-Quezada.
      A steadfast commitment to scientific integrity should be a fundamental quality of all researchers and is central to their pursuit of knowledge for societal benefit. Failure to uphold this integrity can have serious consequences for the researchers involved and the wider community, as demonstrated by scientific publications that report data or results derived from questionable and unethical practices. This study aimed to evaluate retraction rates in scientific literature within the fields of psychiatry and psychology. Using a bibliometric approach, the study analysed retracted articles indexed in the Web of Science over the past ten years, identifying integrity issues in the fields of psychology and psychiatry and categorizing retractions by year, country, journal, category, and index. The results show that, although the number of retractions in psychology and psychiatry has increased, they still represent a smaller proportion of the total number of retractions than other scientific disciplines. In many cases, the reason for retraction is scientific misconduct (65.56 per cent), with only 23.33 per cent of retractions initiated for honest errors. Most of the time (52.22 per cent), editors initiate the retraction. We discuss these results, paying particular attention to the direct and indirect harm caused to individuals in line with the ethical principle of non-maleficence. This highlights the importance of avoiding the citation of retracted publications as evidence in decision-making processes related to mental health interventions.

    A bibliometric analysis of preprints in traditional, complementary, and integrative medicine research.
    Jeremy Y Ng, Brenda X Lin, Sabrina Abdella, Magdalene Abebe, Isabella Y Tao, Holger Cramer.
       BACKGROUND: Traditional, complementary, and integrative medicine (TCIM) encompasses a wide range of healthcare practices and is of growing global interest. Preprints, scientific manuscripts posted prior to formal peer review, offer opportunities to address challenges in TCIM research, including limited funding, publication delays, and concerns about methodological quality. By increasing the visibility and speed of research dissemination, preprints may help strengthen the TCIM evidence base. This bibliometric analysis examined the characteristics of TCIM-related preprints posted on servers with TCIM subject filters.
    METHODS: Preprints were sourced from the ASAPbio preprint server directory, limited to servers with TCIM-related categories. Data extraction (June 4, 2024 to January 14, 2025) included all TCIM-related preprints posted on the selected server from their inception, and collected details such as title, DOI, abstract, authors, affiliations, preprint posted date, publication journal (if applicable), publication date, preprint type, keywords, number of versions, citations, comments, and funding information. Author geographic distribution, collaboration networks, and key research topics were also analyzed.
    RESULTS: Between 2012 and 2024, 1980 TCIM preprints were posted across 11 servers. Research Square hosted the most preprints, and China contributed the highest number. Among the 612 preprints later published in journals, BMC Trials was the most common destination, with a median time of 4.89 months from preprint to publication. Funding information was often missing, but when reported, the National Natural Science Foundation of China was the most frequent sponsor. Overall, citation and comment activity was low. Wellcome Open Research had the highest average citations and comments per preprint among all servers.
    CONCLUSION: This study provides the first in-depth analysis of TCIM preprints, revealing active research areas and important gaps in preprint usage, geographical representation, and post-publication engagement. Findings highlight opportunities to improve transparency and research dissemination in TCIM through more consistent preprint practices and tracking.

    NATIONAL INSTITUTE OF TRAUMATOLOGY AND ORTHOPEDICS: A BIBLIOMETRIC STUDY.
    Rebecca Fiorani de Oliveira Nascimento, João Antonio Matheus Guimarães, Patrícia Cristina Dos Santos Costa.
       Objective: This study aimed to map the scientific production of the National Institute of Traumatology and Orthopedics (INTO) over its 50 years of history.
    Methods: We conducted a descriptive bibliometric study in the PubMed, Scopus, and BVS databases, retrieving 522 articles published between 2007 and 2024. We identified the co-citation networks of INTO-affiliated authors, the keyword networks with the main topics addressed in the publications, and the institution's interaction network with other research and teaching entities.
    Results: There was a progressive growth in publications linked to INTO. In the last six years (2019-2024), the annual average number of publications increased by 44.83% compared with the previous period. The keywords with the highest co-occurrence were related to applied research, mainly with an epidemiological profile, but also to different study designs in basic and translational research.
    Conclusions: The analysis revealed a higher frequency of collaboration with public universities (UFRJ, UFF, UERJ, and USP). The institution's scientific production presented a well-articulated scientific collaboration network. Part of INTO's mission was evidenced through its work in public health research for health promotion in orthopedics and its contribution to the production of data for the formulation of public policies.

    From injury prevention to standardized scoring: a bibliometric analysis of thematic evolution and emerging trends in the development of the breakdance competition system (1984-2026).
    Hang Yin, Xi Ling.
      When Breaking successfully debuted at the 2024 Paris Olympic Games in France, it attracted strong attention from the academic community toward this emerging competitive sport. Given that Breaking is a newly included Olympic sport that urgently requires development and remains controversial, this review aims to conduct a quantitative analysis of the academic research achievements related to the construction of the Breaking competition system over the past more than 40 years. The researchers selected literature from the Web of Science Core Collection and the Scopus database from 1984 to 2026 as data sources and conducted bibliometric and visualization analyses using CiteSpace, VOSviewer, and R Bibliometrix. Meanwhile, analyses were carried out on core journals, core research teams, research countries, hot keywords, as well as the development process and development trends. The results showed that the research field of the Breaking competition system is developing vigorously. The findings are as follows: (1) The United States leads the world by a large margin in the number of publications, while the United Kingdom and Canada rank next in academic influence; several research groups have formed among the core authors, with Yang, Wyon, and Miura being typical examples. It is worth noting that Sato published the largest number of papers over the longest period of time. Among research institutions, the University of Tokyo in Japan has published the largest number of studies, while Dance Research Journal has the greatest influence and the Journal of Dance Medicine and Science has the highest output. Among the journal research areas related to this topic, "MEDICINE, MEDICAL, CLINICAL" and "PSYCHOLOGY, EDUCATION, HEALTH" occupy the frontier of research fields, while "NEUROLOGY, SPORT, OPHTHALMOLOGY" have become the most influential research pathways. (2) This field has experienced three stages of development, namely the spontaneous research phase, the initial development phase, and the Olympic-oriented standardization construction phase, mainly focusing on four areas: terminology origins, medical support, rule framework, and competitive psychology and social adaptation. (3) "Case report" is the longest-lasting research hotspot, while "hip hop" has become the most cutting-edge hotspot keyword. Based on existing studies, future research should develop toward three directions: rule quantification, judging consistency, and cultural and competitive synergy. This review provides scholars in the field of Breaking competition system research with a clear knowledge map and offers theoretical support for policymakers of Breaking competitions to formulate more scientific decisions.

    AI Writing Vocabulary in Ophthalmology: Faster Non-Native Adoption, Unchanged Outcomes.
    Alessandro Berni, Daniel Shu Wei Ting, Greta Caputo, Alessandro Russo, Laura Gutierrez Sinisterra, Alessandro Avitabile, Gianni Virgili, Michele Reibaldi, Fabrizio Giansanti, Daniela Bacherini, Enrico Borrelli.
       PURPOSE: To quantify the change in large language model (LLM)-associated writing vocabulary in ophthalmology after ChatGPT, to test whether it differed by first-author affiliation-country language group, and to determine whether publishing outcomes shifted.
    DESIGN: Retrospective, cross-sectional bibliometric study, with an interrupted time-series analysis of a 10-year publication census.
    SUBJECTS, PARTICIPANTS, AND/OR CONTROLS: Published articles, not human subjects. Primary corpus, 15,683 PubMed abstracts from the 40 highest-impact ophthalmology journals (top 10 per 2025 Journal Citation Reports quartile), pre-ChatGPT (2018-2019) versus post-ChatGPT (2023-2024); supportive corpus, 6,139 open-access full texts; and a 48,468-article census (2015-2024) for outcomes. Articles were grouped by whether the first author's affiliation country was native-English-speaking.
    METHODS, INTERVENTION, OR TESTING: We counted 41 curated LLM-associated excess words per document, with the word count as a Poisson offset and frequency-common control words for specificity. The prespecified primary analysis was the period-by-language-group interaction in a Poisson generalized estimating equation clustered on first author. The instrument was construct-validated against 30 LLM-generated abstracts and against pre-ChatGPT, definitionally LLM-free, human abstracts.
    MAIN OUTCOME MEASURES: The period-by-language-group interaction incidence rate ratio (IRR) for the excess-word rate; and the non-native share of publications and of top-quartile journal placements.
    RESULTS: The excess-word rate rose 2.1-fold, from 320 to 668 per million words. The rise was steeper for non-native-English-affiliated first authors (interaction IRR, 0.61; 95% CI, 0.48-0.78; P < .001), robust to adjustment for journal quartile and country income, to excluding China (IRR, 0.65), and in an independent full-text corpus (IRR, 0.64). The counter separated LLM-generated from human abstracts (area under the receiver operating characteristic curve [AUC], 0.88), whereas per-article discrimination was near chance (AUC, 0.53), confirming a population-level rate rather than a classifier. An interrupted time series showed no post-ChatGPT change in the non-native share of publications or of top-quartile journals.
    CONCLUSIONS: After ChatGPT, non-native-English-affiliated authors in ophthalmology adopted AI-associated writing vocabulary faster than native-affiliated authors, without any accompanying gain in publication frequency or journal placement. The measure reflects population-level AI-associated style, not fluency, quality, or confirmed AI use, and should not be used to classify individual articles.

    Scholarly Output and Match Outcomes Among Otolaryngology Research Fellows: A Bibliometric Cohort Study.
    Samantha Little, Jack Nickles, Amudalat Aweda, Ebunoluwa Omoniyi, Jordan Tanyi, Rakshak Ravichandran, Scott Selinger.
      ObjectiveMedical students applying to Otolaryngology-Head and Neck Surgery (OHNS) increasingly complete a dedicated research year, yet the relationship between research-year output and match success is poorly defined. We compared research-year scholarly output between fellows who did and did not match into OHNS and examined whether output and home program status were associated with matching.MethodsWe conducted a retrospective bibliometric cohort study of 82 research fellows from 10 OHNS research fellowship programs. PubMed-verified publications were counted at application, at residency start, and cumulatively.ResultsSixty-two of 82 fellows (75.6%) matched into OHNS. OHNS-matched fellows had higher research-year-associated publication counts than non-OHNS-matched fellows, with a median of 1 vs 0 at application (p=0.006) and 5 vs 3 at residency start (p=0.005) and more had ≥1 first-author publication at application (45.2% vs 15.0%; p=0.02). Each additional research-year publication at application was associated with higher odds of matching (OR 1.68; 95% CI, 1.19-2.82; p=0.02). Home-program status was not associated with matching (adjusted OR 1.74; 95% CI, 0.55-5.45; p=0.34).ConclusionsGreater research-year publication output, both at the time of application and at the start of residency, was associated with matching into OHNS, whereas home-program status was not.

    Institutional Research Collaborations and Match Outcomes in Orthopedic Surgery Residency: A Cross-sectional Analysis of 954 Residents.
    Bryce Michael, Adrian Bozocea, Diego Garcia, Amogh Gadekar, Shai Josephs, Gregory Golladay, Dawn LaPorte, Savyasachi Thakkar.
       OBJECTIVE: To determine whether publishing at a given institution is associated with matching there for orthopedic surgery residency, and whether this association reflects publication presence or sustained concentration of work at an institution, with exploratory analyses of publication network characteristics.
    DESIGN: Cross-sectional bibliometric analysis of the 2024 to 2025 NRMP and military match cycles using manually verified publication data with institutional affiliations. Primary analysis used chi-square tests and logistic regression with Bonferroni correction (α = 0.025) to examine associations between institutional publication affiliations and match outcomes.
    SETTING: Multi-institutional analysis of 221 ACGME-accredited orthopedic surgery residency programs across the United States.
    PARTICIPANTS: Of 954 matched first-year orthopedic surgery residents, with verified publication data obtained for 661 residents (69.3%) comprising 4077 PubMed-indexed publications classified by institutional affiliation as home or external with network characteristics.
    RESULTS: Among residents with verified publications (mean 5.92 publications per resident, median 3.0), 165 (25.0%) matched at an institution where they had previously published, compared with 3.8% expected by chance (χ² = 178.3, p < 0.001). To distinguish whether this association reflected publication presence or sustained engagement, we used the home institution-identifiable for every applicant-as a test case. Of 153 (23.1%) matched at home, but having a single home institution publication was not associated with home matching (19.6% vs 18.8%, p = 0.865); however, the proportion of publications at the home institution was the strongest predictor of home matching (odds ratio = 2.17, 95% confidence interval: 1.27-3.73, p = 0.005).
    CONCLUSIONS: Publishing at a residency program was strongly associated with matching there, at a rate approximately 7 times higher than chance. The mere presence of a home institution publication did not predict home matching, but the proportion of publications concentrated at the home institution did. These findings suggest that sustained research engagement at target programs may be meaningfully associated with match outcomes.

    Longitudinal changes in women's representation in spine surgery: a 10-year medicare database analysis.
    Selena Ding, Matthew Miyasaka, Madison Leone, Mia Chang, Junho Song, Yunsoo Lee, Samuel Cho.
       PURPOSE: While the number of women entering orthopedic and neurosurgery residencies has increased, it remains unclear to what extent female representation has increased in spine surgery. The purpose of this study was to assess longitudinal changes in women's representation among spine surgeons, along with their share of spine procedures.
    METHODS: We evaluated all index spine procedures billed in the Medicare Provider Utilization and Payment Data: Physician and Other Practitioners dataset from 2013 to 2022. Revisions, additional levels, and procedures not billed by a self-identified orthopedic or neurosurgeon were excluded. Longitudinal trends in the number of surgeons billing index spine procedures were assessed, stratified by gender and specialty. Similarly, we also compared trends in the number of overall and unique procedures billed.
    RESULTS: In total, 6620 unique surgeons were included, consisting of 6371 men and 249 women. Female representation modestly increased over the study period. However, female surgeons billed for fewer overall and unique spine procedures per year over the study period than men, and there were no significant trends over time. Conversely, while women were underrepresented in the top 25% of surgeons by volume, there were no significant differences in volume or unique CPT codes between men and women in the high-volume cohort.
    CONCLUSION: Our study evaluated longitudinal trends in female representation in spine surgery. We identified increases in the number of female spine surgeons over time, but this did not translate into a significant increase in their share of spine procedures. Our findings may inform future efforts to improve opportunities for women trainees.

    Bibliometric Analysis of Artificial Intelligence Use in Small Animal Thoracic Radiography.
    Vildan Aslan Canatan, Ender Uzabaci.
       BACKGROUND: Artificial intelligence (AI) is increasingly used in veterinary diagnostic imaging, particularly in thoracic radiology, to support image interpretation.
    OBJECTIVE: The aim of this study was to evaluate research trends in AI applications for small animal thoracic radiography through bibliometric analysis, identifying key contributors, leading journals, thematic focuses and collaboration patterns.
    METHODS: Studies published between 2018 and 2025 were retrieved from the Web of Science (WoS) and PubMed databases using predefined Boolean search terms. After duplicate removal and screening based on inclusion and exclusion criteria, 27 articles were included. Data were analysed using RStudio (Biblioshiny) to evaluate publication trends, citation impact, scientific productivity, collaboration networks and thematic structures.
    RESULTS: Publications showed an increasing trend, with an annual growth rate of 10.41% and a peak in 2023 (n = 8). Studies published in 2020 showed the highest citation impact, averaging 46.33 citations. T. Banzato emerged as the most prolific author, while S. Burti authored the most cited study. The United States (n = 32) and Italy (n = 23) were the leading contributing countries. Thematic analyses demonstrated a primary focus on convolutional neural network (CNN)- and deep learning-based automated detection of cardiomegaly, pleural effusion and pulmonary diseases in dogs, reflecting the clinically driven nature of early studies. A significant positive correlation (p < 0.001) was found between WoS citation counts and those from other databases, whereas other bibliometric indicators showed no significant associations.
    CONCLUSIONS: AI shows considerable potential to support diagnostic processes in veterinary thoracic radiology; however, dataset heterogeneity and species diversity remain major limitations, highlighting the need for methodological standardization and stronger international collaboration.

    Mapping the generative era: a bibliometric and specialty-focused analysis of large language models in healthcare.
    Jianding Peng, Yao Tuo, Gang Wang, Ruiqin Han, Qing Wang, Yi Wang, Zixin Hu, Xiaofei Hu.
      Large language models (LLMs) have been rapidly adopted in healthcare since 2022; however, field-level trends and specialty differences remain poorly characterized. This study aims to map the research landscape of LLMs in healthcare and generate comparative specialty profiles through a bibliometric analysis using the Web of Science Core Collection (2015-2025), including English-language articles and reviews analyzed for publication and citation trends, leading countries, institutions, authors, journals, co-citation networks, and keyword structures with VOSviewer and CiteSpace, with sub-analyses for medicine, general and internal; surgery; and radiology, nuclear medicine and medical imaging. Of the 2226 articles included, the annual output increased from four publications in 2022 to 1327 in 2025, yielding a compound annual growth rate (CAGR) of 592.26%; the United States of America contributed 43.5% of the publications, followed by China (14.3%), Germany (9.2%), Turkey (9.0%), and England (6.8%); the publications for each specialty were surgery (31.7%), medicine, general and internal (24.2%), and radiology, nuclear medicine and medical Iimaging (13.0%), with the last demonstrating the fastest 2023-2024 growth (CAGR 265%); and the collaboration networks were United States of America-centered, with dense trans-Atlantic ties. LLM research in healthcare is expanding rapidly with distinct specialty-specific trajectories, and interpreting these trajectories using the DECIDE-AI (developmental and exploratory clinical Iinvestigations of decision support systems driven by artificial intelligence) framework clarifies low-risk near-term applications and monitoring priorities, providing a specialty-aware baseline to support the safe, equitable, and regulation-aligned adoption of LLMs in clinical practice.

    A bibliometric analysis of research evolution on peritoneal metastasis in colorectal cancer (2000-2026): advances in molecular mechanisms and therapeutic strategies.
    Shirui Lu, Xiaolu Du, Hongliang Luo, Fangteng Liu.
       BACKGROUND: Peritoneal metastasis from colorectal cancer (pmCRC) is a major form of distant spread and generally confers a poor prognosis. This study aimed to evaluate its global research activity, hotspots, and emerging trends through a bibliometric analysis.
    METHODS: We searched the Web of Science Core Collection, PubMed, and Scopus for English-language pmCRC articles and reviews published from January 1, 2000, to March 31, 2026. Bibliometric analyses were performed using tools such as CiteSpace (v6.3), VOSviewer (v1.6.20), and R software (v4.5.0).
    RESULTS: A total of 1,611 publications were included. The United States produced the highest number of publications (n = 304), followed closely by China (n = 289) and the Netherlands (n = 203). Catharina Hospital emerged as the most productive institution (74 publications), while Ignace H.J.T. De Hingh was identified as the leading contributor based on publication volume and co-authorship linkage strength. Annals of Surgical Oncology was the most influential journal (161 publications). Keyword cluster analysis revealed four major research themes: surgical treatment, molecular mechanisms, chemotherapy, and prognosis. Citation burst analysis showed that "multicenter" had the highest burst strength, while "circulating tumor DNA" and "machine learning" have emerged as recent ongoing hotspots.
    CONCLUSIONS: This bibliometric analysis provides an overview of pmCRC research over the past two decades. The field has evolved from optimizing surgical techniques toward molecular exploration and precision medicine. Emerging hotspots, including ctDNA, machine learning, and multicenter trials, point toward dynamic multi-omics monitoring and collaborative clinical validation.

    The scientific evolution of the Ommaya reservoir: a bibliometric analysis.
    Fatimah M Coppin, Nicholas M Cordero, Jonathan Hus, Randy S D'Amico.
       BACKGROUND: Since its introduction in 1963, the Ommaya reservoir has expanded beyond its original role as a ventricular access device to support intrathecal therapeutics, cerebrospinal fluid diagnostics, and emerging applications in precision neuro-oncology. To our knowledge, the evolution of this research landscape has not been quantitatively characterized.
    METHODS: We analyzed Web of Science Core Collection publications on June 19, 2026, retrieving 896 articles, of which 862 were included (English, unique DOI, complete metadata). Bibliometric analyses included publication trends, author impact, international collaboration mapping, keyword co-occurrence networks with spectral clustering, temporal overlay visualization, and abstract n-gram analysis. Analyses were performed in MATLAB v2025a.
    RESULTS: Output increased from 1 to 3 articles annually in the 1960-1970 s to a peak of 67 in 2024, with nearly 90% of publications appearing within the past two decades. The United States contributed 323 publications (37.5%) and was the central collaboration hub. Four dominant themes emerged: neuro-oncology and intrathecal therapeutics, hydrocephalus and device-related complications, craniopharyngioma management, and surgical techniques with drug delivery. N-gram analysis revealed rapid emergence of "liquid biopsy" and "immunotherapy" in recent abstracts. Temporal analyses demonstrated a progressive shift in research from ventricular drug delivery toward cerebrospinal fluid biomarkers, molecular diagnostics, immunotherapy, and targeted therapeutics.
    CONCLUSIONS: Ommaya reservoir research has evolved from ventricular access and intrathecal drug delivery toward molecular diagnostics and precision neuro-oncology. Rather than reflecting device changes, these trends illustrate the expanding role of cerebrospinal fluid as both a therapeutic and diagnostic compartment in modern neuro-oncology.

    Global disparities in neurosurgical literature: a narrative review of underrepresentation of low- and middle-income countries and pathways to research equity.
    Tirath Patel, Naveed Ahmad, Abbas Hussain, Bisma Faraz, Amna Binte Naeem, Urooj Sheraz, Laiba Noor, Saleha Khan, Muhammad Seerat Ali, Hafiza Tooba Siddiqui, Taimur Iqbal, Bhumi Daishik Patel, Nikhilesh Anand.
      The global neurosurgical literature is dominated by high-income countries, with low- and middle-income countries (LMICs) contributing minimally despite bearing the most significant share of the neurosurgical disease burden. Underrepresentation limits equitable knowledge dissemination and the relevance of guidelines. The objective of this review was to assess neurosurgical publication disparities, identify deterrents to LMIC participation, and outline initiatives that foster equity and inclusion in research. This narrative review synthesized evidence on global disparities in neurosurgical literature through a structured search of PubMed, Scopus, and Google Scholar (2010-2025). Eligible studies examined research output, authorship trends, publication barriers, or equity initiatives. Findings mapped bibliometric patterns, highlighted structural barriers, and synthesized strategies to promote equitable neurosurgical scholarship. More than two-thirds of neurosurgical reviews come from North America and Europe, whereas less than 10% come from Africa and South-East Asia. Barriers to publication include limited funding, high article processing charges, lack of mentorship, and weak institutional infrastructure. LMIC authors are often relegated to middle authorship, which decreases exposure and hinders academic advancement. Case studies from Africa, South Asia, and Latin America highlight progress in expanding the workforce and in training for specific areas, but persistent research inequities remain. Recent initiatives, such as AuthorAID, HINARI, African Neurosurgical Research Collaborative, and open-access waiver programs, have demonstrated measurable improvements in LMIC research output and authorial independence. Significant inequities persist in neurosurgical research. For sustainable solutions, there is an important need for structural reforms: expanded mentorship, equitable funding, inclusive editorial policies, and strengthened regional collaborations that ensure global neurosurgical research reflects diverse contexts and meaningfully contributes to worldwide patient care.

    Comparison of training background and characteristics between osteopathic and allopathic team physicians in professional sports leagues.
    Brandon D Rust, Ambika Singh, Matthew T McKinley, Joseph Imler, Mackenzie Elting, Ryan Callahan, Christopher L Rennie, Leighann C Krasney.
       CONTEXT: Team physicians (TPs) play a critical role in professional sports, providing medical care for athletes under high-pressure conditions. These positions are highly competitive, influenced by previous affiliations, training pedigree, and institutional connections, with fellowship training increasingly essential. Although the number of osteopathic (Doctor of Osteopathic Medicine [DO]) physicians in the United States has grown substantially, TPs in professional sports remain predominantly filled by allopathic (Doctor of Medicine [MD]) physicians, and the training pathways of DO TPs are not well characterized.
    OBJECTIVES: The objective of this study is to compare the training and demographic characteristics of DO and MD TPs in professional sports leagues.
    METHODS: Publicly available sources were utilized to identify all DO and MD physicians serving as head team physicians (HTPs), TPs, or consulting physicians across seven major US professional sports leagues (National Football League [NFL], Major League Baseball [MLB], National Basketball Association [NBA], Women's National Basketball Association [WNBA], National Hockey League [NHL], Major League Soccer [MLS], and National Women's Soccer League [NWSL]). Data on gender, specialty, medical education, residency and fellowship training, years in practice, clinical practice type, practice setting, and research productivity were collected across the leagues for both osteopathic and allopathic training backgrounds.
    RESULTS: Among 676 TPs and consultants, most were MDs (93.3 %) and male (91.3 %), with DOs more often being female (22.2 % vs. 7.8 %) and in early-career stages (p<0.05). Specialty distribution differed by degree, with DOs overrepresented in Family Medicine (15.6 %) and underrepresented in orthopedic surgery (1.2 %) (p<0.001). Training locations partially aligned with current team affiliation, particularly for residency, but research productivity did not differ by degree. The majority practiced in urban settings within private or academic institutions, although DOs were less frequently urban-based (5.0 %) than MDs (p=0.028).
    CONCLUSIONS: US professional sports team physicians (PSTPs) are predominantly MD-trained and male, with DO physicians and women underrepresented, especially in orthopedic surgery. Career stage, research productivity, and practice settings were generally similar across degree types, highlighting potential external factors, such as the presence of longstanding institutional affiliations and informal referral networks, that may influence access to these roles.

    Behind the wall of industry payments: An individual factor analysis of gender disparities in consulting fees and royalties to U.S. cardiothoracic surgeons.
    Sofia W Viana, Brenda Feres, Mallika Desai, Anthony Kachulkin, Muhammad Umar Nasir, Moeen-Ud-Din Muhammad, Catherine E Kelty, Mariana Ferrari, Sandra L Starnes, Jennifer S Lawton, Mecker G Moller, Robert M Van Haren.
       BACKGROUND: Less is known about gender-based differences in industry-sponsored payments within cardiothoracic surgery. We evaluated the magnitude and drivers of these disparities in the United States.
    METHODS: A retrospective cross-sectional analysis was conducted from the 2023 Centers for Medicare & Medicaid Services Open Payments Database, including consulting fees and royalty payments.
    RESULTS: Among 468 payments totaling $9,384,973, men received 91.2% ($8,618,735) and women 8.8% ($766,238) of total payments. Men received higher median consulting payments than women ($6536 vs. $6000; p = 0.004). Women were more likely to be early/mid-career, more represented in thoracic surgery (56.1% vs 35.8%), and less likely to hold chief positions (7% vs 27%) or have >10 years of practice (51% vs 82%), all p < 0.0.5. In univariate analysis, >10 years in practice was associated with higher payments.
    CONCLUSION: Significant gender disparities persist and appears to be a multifactorial issue drive by inequities in leadership and seniority.

    A Ten-year Review of Sex-based Representation at the Orthopaedic Trauma Association Annual Meeting.
    Jaquelyn Kakalecik, Emily K Krisanda, Marissa N Pazik, Diana V Rijo, Jennifer E Hagen, Michael T Talerico.
       BACKGROUND: Although female representation at national orthopaedic society meetings has increased in recent years, women remain disproportionately more likely to deliver nontechnical presentations. Examining patterns in speaker roles provides a measurable way to assess progress toward equitable representation by sex in academic orthopaedic settings.
    QUESTIONS/PURPOSES: This study aimed to (1) evaluate trends in female speaker representation at the Orthopaedic Trauma Association (OTA) Annual Meeting from 2014 to 2024 and (2) assess sex-based differences in speaker roles, including the likelihood of delivering technical versus nontechnical presentations.
    PATIENTS AND METHODS: Speaker names, session titles, and roles (speaker, moderator, or committee member) were extracted from OTA Annual Meeting programs spanning 2014 to 2024. Sessions were classified as technical or nontechnical, and speaker sex was determined through publicly available information. A total of 514 sessions were analyzed, including 390 technical and 124 nontechnical sessions. Trends in speaker roles by sex were assessed over time, and odds ratios (ORs) were calculated to evaluate the likelihood of men versus women delivering technical presentations.
    RESULTS: Female representation increased across all roles over the study period. The proportion of female speakers rose from 8.85% in 2014 to 22.22% in 2024, and the proportion of female moderators increased from 4.84% to 12.99%. Four women served as committee members since 2021, with one serving as cochair. Men were significantly more likely to give technical talks in 2024 (OR 2.8, 95% CI, 1.47-5.41, P = 0.0018) and 2021 (OR 3.0, 95% CI, 1.59-5.87, P = 0.0009).
    CONCLUSION: Female representation at the OTA Annual Meeting has increased substantially over the past decade, mirroring trends observed in other orthopaedic subspecialty societies. However, sex-based differences in the distribution of technical versus nontechnical presentations were observed in multiple years. Continued efforts are needed to promote equitable access to academic and leadership roles for women in orthopaedic trauma.

    Evaluation and Ranking for Scientific, Transparent and Applicable of Chinese Geriatrics Guidelines and Consensus Published in 2023.
    Specialized Committee for Geriatric Medicine of the STAR
       Objectives: This study aims to evaluate the Scientific, Transparent, and Applicable Rankings (STAR) of guidelines and consensus published in Chinese geriatric medicine journals in 2023.
    Methods: The working group conducted a systematic search in eight major Chinese and English databases for guidelines and consensuses published by Chinese scholars in the field of geriatric medicine in 2023. The selected guidelines and consensuses were rated using the STAR rating tool, and the rating results were analyzed.
    Results: A total of 10 guidelines and 20 expert consensus documents were included. The STAR scores ranged from 9.4 to 55.7 with a mean of 29.3 ± 11.2. The STAR scores of 10 guidelines ranged from 16.1 and 55.7 with an average of 35.5 ± 13.1. The STAR scores of 20 consensus ranged from 9.4 and 48.5 with an average of 26.2 ± 8.9.
    Conclusion: Guidelines and consensus in geriatric medicine have shown significant improvements in 2023 compared to 2022 across registration, consensus methodology, working groups, and accessibility. However, areas such as protocol development, funding, and clinical issues require further refinement by the authors.

    The best time to become a parent: The relationship between tenure and fertility among academics.
    Olga Gorodetskaya, Agnese Vitali, Valentina Tocchioni, Alessandra Minello.
      The interplay between career progression and fertility remains a central theme in the scholarly debate on academia. Past research has largely examined the influence of parenthood on academic careers, revealing a motherhood penalty for women and mixed results for men. The converse-whether and how career advancements shape fertility decisions-remains underexplored. This contribution pioneers the study of the relationship between academic career progression, specifically tenure attainment, and fertility for academic women and men. Drawing on unique primary data from a large sample of Italian academics, this study employs discrete-time event-history models to analyze transitions to first and second childbirths, and logistic regression models to assess short-term fertility intentions by career stage and gender. Results reveal that job stability facilitates the transition to parenthood: tenure significantly increases the hazard of becoming a parent for men and, when obtained before age 35, for women. Tenure also significantly boosts short-term fertility intentions among childless women. Instead, tenure is unrelated to the transition to a second birth for either women or men. The positive association between tenure and fertility raises important concerns. Gender differences in the upper age limits to fecundity translate into shorter reproductive lifespans for women than for men. In academia, these differences are exacerbated by women's later age of promotion compared to men. This results in a considerably shorter post-tenure fertility window for women, leading to higher rates of childlessness and lower fertility compared to men. Policies aimed at reducing gender disparities in academia should address these differences in fertility by supporting academic women in transitioning to parenthood.

    Follow-up investigation of ethics approvals and regulatory compliance in publications from the IHU-Mi.
    Fabrice Frank, Elisabeth M Bik, Gideon Meyerowitz-Katz, Jérôme Barriere, Éric Billy, Véronique Saada, Alexander Samuel, Jacques Robert, Lonni Besançon.
       BACKGROUND: Following our previous investigation of 456 articles published by the IHU-Méditerranée Infection (IHU-Mi) institute in Marseille, France, subsequent editorial actions, institutional reviews, and reports from French authorities provided additional evidence relevant to our concerns. We therefore extended our investigation to the broader IHU-Mi bibliography to assess potential breaches of the Declaration of Helsinki, French regulations governing research involving human participants, and the consistency between reported studies and the ethics approvals cited.
    METHODS: We assessed 2,674 IHU-MI publications identified through PubMed, Google Scholar, PubPeer, and manual searches. We excluded articles not reporting research involving human participants, articles clearly reporting retrospective studies without ethics flaw, and articles for which editorial investigations had clarified our concerns. We compared the remaining articles with the relevant French legal framework and, where available, with ethics approvals obtained through public transparency procedures or other sources.
    RESULTS: We identified ethical or legal concerns in 853 articles from this institute. These included at least 75 articles with retrospective approvals, 194 describing research conducted abroad without mention of local approvals, 343 not mentioning ethics approval, and 426 describing sample collection from healthy volunteers with concerns. Among 374 articles for which we obtained the cited ethics approval documents, at least 304, or 81.3%, described sample collections that were not covered by the corresponding approval. Since our previous investigation, editorial and institutional responses have led to 64 retractions and 270 expressions of concern, and have clarified or substantiated many of the concerns raised. We also found that the local ethics committee issuing most of the approvals may not have been sufficiently independent from the authors.
    CONCLUSION: Institutional reports and editorial decisions have substantiated many of the concerns identified in our analysis, although a small subset of cases was attributable to unintentional errors. Our findings indicate widespread and longstanding problems in research ethics compliance within the IHU-Mi bibliography and support the need for continued editorial and institutional review.

    Trends in Sex Representation in the American Society for Surgery of the Hand Committee and Annual Meeting Leadership from 2013 to 2024.
    Abel Ruiz Diaz, Stephanie Malta, Micah K Sinclair, Angelo R Dacus, A Bobby Chhabra.
       Purpose: To evaluate longitudinal trends and distribution of sex representation within leadership positions of the American Society for Surgery of the Hand (ASSH) over the past decade.
    Methods: Demographic data from 2013 to 2024 were obtained from ASSH for committee and annual meeting leadership positions. Self-reported sex was analyzed, and leadership participation was assessed longitudinally and by distribution among unique individuals.
    Results: A total of 685 ASSH committee leadership positions were identified, of which the majority were held by men. Women representation in committee leadership increased over the study period. Key decision-making positions, such as committee Chair, represented a large proportion of all leadership opportunities, with women chairs accounting for a smaller share overall. Leadership positions were concentrated among a limited number of individuals, particularly among women leaders. Across leadership for the ASSH national meeting, women participation increased over time but remained lower than men. A disproportionate share of leadership positions was held by a small subset of individuals, with a greater concentration observed among women leaders compared with men.
    Conclusions: Women representation within ASSH leadership has increased across committee and annual meeting leadership positions over the past decade. However, these leadership opportunities remain concentrated among a small number of recurring individuals, suggesting that gains in numeric representation have not fully translated into broader diversification of leadership. These findings highlight the importance of considering both representation and distribution when evaluating inclusivity within surgical societies.

    Timeliness of publication of randomized controlled trials in rheumatology: A systematic review.
    Pankaj Bansal, Nasim A Khan, Harsimar Singh, Mahrukh Siddiqui, Jennifer Schram, Shreya Patel, Shailey Karri, Alexa Constantakos, Nivedita Sundararajan, Ian J Saldanha.
       OBJECTIVE: To systematically review the (1) timeliness of publication of randomized controlled trials (RCTs) in rheumatology, (2) impact of the COVID-19 pandemic on time to publication, and (3) factors associated with publication delays.
    METHODS: We searched Medline, Embase, EBM Reviews, Cochrane Central Register of Controlled Trials, and Scopus from January 1, 2018, to June 30, 2023 for Phase 3, superiority, parallel-design RCTs that evaluated any treatment for a rheumatologic illness or a rheumatologic treatment for COVID-19 and reported clinical primary efficacy outcome. Outcomes of interest were time to publication after trial completion and publication delay of >2 years after trial completion.
    RESULTS: 448 RCTs were included in this systematic review. Median time from completion to publication was 549 days and 65.9 % RCTs were published within 2 years of completion. Compared with RCTs on rheumatologic diseases, RCTs on COVID-19 were published sooner (253 vs. 549 days; p < 0.001) and were more likely to be published within 2 years (adjusted OR 9.49, 95 % CI 2.07 to 43.61). Compared with RCTs completed before March 1, 2020, RCTs completed after March 1, 2020, were published sooner (327 vs. 724 days; p < 0.001) and were more likely to be published within 2 years (adjusted OR 9.40, 95 % CI 5.14 to 17.21). Time from RCT completion to submission accounted for most (67 %) of the time to publication.
    CONCLUSIONS: Publication delay continues to be an important concern in dissemination of clinical research. Most of the delays in publication were attributable to delays in submission to journals after trial completion.
