       OBJECTIVE: This study focuses on characterizing the voices that are amplified through peer reviewed publication and how they relate to one another. This study aims to 1) identify patterns of author collaboration and representation, 2) assess how this varies among different journals, 3) examine the relationship between author collaboration and quantitative publication.
    METHODS: This is a bibliometric analysis using descriptive statistics and network analysis, examining all publications in four influential emergency medicine journals from January 2015 through December 2024. Authors and journals were assessed on quantity of publications, patterns of co-authorship, and network characteristics of individual and aggregate journals.
    RESULTS: There is a sharp right-skew of authorship - most authors have only a single article published in ten years. The most prolific authors in emergency medicine demonstrate significantly more publications than their peers. Journals show a propensity to publish multiple articles from a small number of authors, but there is variation among journals as to how many unique authors appeared during the timeframe studied. There was a gender disparity identified among the top authors, most of whom were men.
    CONCLUSION: Bibliometric analysis is able to demonstrate academic influence while also casting light on the role of journals in peer-reviewed publication patterns. Publication is a vital component of academic success and tangible evidence of professional influence. How authors collaborate and journals select manuscripts is impactful, and unfortunately this study demonstrates inequity among the most visible authors in the most impactful journals.

       PURPOSE: Research is an important factor in matching into gastroenterology (GI) fellowship, yet limited data exist on the publication output of incoming fellows. The purpose of this study was to investigate the peer-reviewed publications of matched GI fellows by start of internal medicine (IM) residency and GI fellowship to characterize research trends in the GI fellowship match.
    METHODS: A bibliometric analysis was performed on fellows entering GI programs in 2022-2024. Utilizing research databases, the quantity and quality of publications at the start of both IM residency and GI fellowship were extracted and analyzed temporally, by home-program match status, and degree type.
    RESULTS: Across 192 programs, 1858 fellows had a median of 0 publications before IM residency, increasing to 3 publications by GI fellowship (mean: 1.32 vs. 5.08). At IM application, 50.9% had no publications, compared to 16.8% at GI application. By fellowship, matriculants averaged 36.1% first/last authored articles, 2.33 H-index, and 61.9% GI-related articles. Those remaining at their home program for fellowship had fewer publications than external matches. Non-US IMGs had more publications and higher H-indexes but published in lower-impact journals than allopathic graduates.
    CONCLUSION: Our findings suggest that research productivity increases between IM and GI applications, while providing background on current trends in other quality metrics in the match. Those who matched their home institutions had fewer mean publications than those who did not, suggesting that institutional familiarity may play a role. These findings can help applicants, advisors, and program directors set expectations and goals regarding research during the GI fellowship match.

       BACKGROUND: Gender diversity in authorship enhances the inclusivity and breadth of perspectives in medical research, yet disparities persist across many disciplines, including allergy and immunology. In Canada, women represent the majority of the allergy and immunology workforce, yet it remains unclear whether this is reflected in authorship and academic leadership.
    OBJECTIVE: This study examines trends in gender diversity among authors in Allergy, Asthma & Clinical Immunology (AACI), focusing on first, last, and single-author roles, and explores collaborative trends among women authors.
    METHODS: Metadata for AACI articles published from 2011 to 2023 were retrieved using the Web of Science database. Author gender was predicted using the genderize.io tool, supplemented by manual verification for ambiguous cases. Articles with undetermined gender were excluded. Descriptive statistics and logistic regression were employed to identify trends and associations.
    RESULTS: Of 929 articles, 891 with 5,541 authors were included. Women represented 43.4% of all authors. By role, women comprised 50.8% of first authors, 33.8% of last authors, and 29.4% of single authors. The proportion of women-women first and last author pairs increased significantly from 4.8% in 2011 to 26.9% in 2023 (p = 0.03). Articles with women as last authors were more likely to feature women as first authors (OR = 1.46, 95% CI: 1.10-1.93, p = 0.009).
    CONCLUSION: Although there have been positive trends toward gender parity in AACI authorship, disparities persist, particularly in leadership roles and specific article types. Continued efforts are required to foster equitable representation in allergy and immunology research.

       BACKGROUND: Historically, systemic barriers have limited women's participation in surgical training and academia. Whilst the representation of women among surgical trainees has increased globally, continued examination of gender inequality within surgical academia is necessary to ensure holistic and sustainable diversity. This study explored the association between student and supervisor gender and research outcomes and assessed temporal trends in gender representation within a postgraduate surgery coursework degree.
    METHODS: A retrospective cohort study was conducted among students who completed the Master of Surgery dissertation subject at The University of Sydney between 2010 and 2021. Data included dissertation mark, publication rate, time to publication, citation count, journal impact factor and total publications within 2 years. Outcomes were compared by student and supervisor gender, and student-supervisor dyads, using Mann-Whitney U, chi-squared and Kruskal-Wallis tests. Temporal trends were analysed using regression models.
    RESULTS: A total of 424 students were included (305 men, 119 women). Dissertation mark and short-term research outcomes did not differ by student gender with both having a median of one publication. Students supervised by men had higher dissertation publication rates (56% vs. 30%, p < 0.001) and more publications within 2 years (median 1 vs. 0, p = 0.009) than those supervised by women. Woman-woman student-supervisor dyads were less likely to publish their dissertation (29%) than man-man (57%) and woman-man dyads (53%) (p = 0.006). While the number of women supervisors increased over time, the number of women students and the proportional representation of women students and supervisors remained unchanged.
    CONCLUSION: Academic performance and short-term research outcomes were similar by student gender, suggesting that disparities in surgical training and academia are unlikely to be explained by differences in academic capability or early research productivity. Differences associated with supervisor gender and persistent under-representation highlight ongoing structural influences on academic productivity, and the need for sustained, system-level equity initiatives across the surgical training pipeline.

       Introduction: Competition for orthopaedic surgery residency positions has intensified in recent years, coinciding with the shift of the United States Medical Licensing Examination Step 1 and many medical schools' curricula to pass/fail grading. Consequently, residency programs have placed greater emphasis on applicants' research productivity. The average number of research items listed on applications has quadrupled since 2011. However, it is unclear whether preresidency research productivity predicts long-term research output. This study evaluates the association between preresidency research productivity and future publication output.
    Methods: A retrospective cohort of 822 applicants to a single US orthopaedic surgery residency program during the 2010 application cycle was evaluated. Electronic Residency Application Service (ERAS) data collected included the number and total hours of research experiences, total research items, oral/poster presentations, and manuscript publications. Each publication was cross-referenced using Scopus and PubMed to determine citation counts and publication in a top-15 orthopaedic journal. Applicants were matched to publicly available Scopus profiles to assess post-ERAS submission research productivity. The primary outcome was the number of post-ERAS publications. The 309 applicants without Scopus records were excluded from the study. Associations between variables were analyzed using Spearman's correlation, with statistical significance set at p < 0.05.
    Results: Post-ERAS publication count was significantly correlated with the number of poster/oral presentations (P = 0.023) and publication in a top-15 orthopaedic journal (P = 0.027). However, post-ERAS publication count was not significantly associated with the number of research experiences (P = 0.129), research hours (P = 0.501), total research items (P = 0.571), manuscript count (P = 0.713), or cumulative citations from application manuscripts (P = 0.308).
    Discussion: Poster/oral presentations and publication in a top-15 orthopaedic journal were the only ERAS metrics associated with postapplication publication output. Total research items, manuscripts, and citations were not correlated with continued productivity. Qualitative indicators of research engagement, such as presentations and publication quality, were associated with continued publication output, whereas quantitative metrics were not. These findings suggest that meaningful research involvement, rather than volume alone, better predicts long-term publication output.

      Funding agencies use a variety of mechanisms to fund research. The National Institutes of Health in the United States, for example, employs scientists to perform research at its own laboratories (intramural research), and it also awards grants to pay for research at external institutions such as universities (extramural research). Here, using data from 1594 intramural grants and 97,054 extramural grants funded between 2009 and 2019, we compare the scholarly outputs from these two funding mechanisms in terms of number of publications, Relative Citation Ratio, and clinical metrics. We find that extramural awards are more cost-effective for producing outputs commonly used for academic evaluation, such as publications and citations (per dollar), while intramural awards are more cost-effective for generating research that influences future clinical work, more closely in line with the agency's health goals. These findings provide evidence that institutional incentives associated with different funding mechanisms drive their comparative strengths.

      "Publish or perish" is a grim reality for many academic surgeons and has led to authorship proliferation and internationalization of the cardiothoracic surgical literature. We sought to examine whether these trends are continuing today. We reviewed 17 267 articles from 2007 to 2022 in the archives of the 3 leading cardiothoracic journals (European Journal of Cardiothoracic Surgery, EJCTS; Journal of Thoracic and Cardiovascular Surgery, JTCVS; Annals of Thoracic Surgery, ATS). Data on the number of authors and geographic origin were collected. The mean number (± SE) of authors per article increased with time for all journals: from 6.5 ± 0.1 in 2007 to 9.0 ± 0.2 in 2022 for the EJCTS (P < .001), from 7.4 ± 0.1 in 2007 to 8.2 ± 0.2 in 2022 for the JTCVS (P < .001), and from 6.9 ± 0.1 in 2007 to 9.0 ± 0.2 in 2022 for the ATS(P < .001). North American institutions increasingly dominate JTCVS/ATS, whilst European manuscripts decline in all journals. Only EJCTS showed increasing internationalization. Authorship proliferation continues in the 3 leading cardiothoracic surgical journals, reflecting the natural evolution of the demands of modern research and career progression.

       Background: Determine the statistical report quality of articles published in dental journals according to the level of impact of the journal and the study design.
    Methods: A random sample of original articles published in four journals of General Dentistry indexed in Scopus was evaluated, two high-impact (quartile 1) and two medium-impact (quartile 3). The study design was recorded as observational, experimental, or other. The quality of each report was assessed through seven statistical error indicators. Two statisticians independently evaluated the articles and then contrasted their results; in the case of discrepancies in the ratings, they reached an agreement to establish a consensual criterion. Chi-square, Fisher's exact, Mann-Whitney U, and Kruskal-Wallis tests were applied with post hoc Dunn-Bonferroni correction.
    Results: The presence of at least one statistical error was high (85.6%), with 123 (83.7%) and 44 (91.7%) articles in high- and medium-impact journals, respectively. Two statistical errors were more common (32.3%). We found a relationship between the presence of some errors (P = 0.009) and the number of statistical errors (P = 0.011) with the study design.
    Conclusions: There is a low-quality statistical report of the evaluated dental articles, as errors are very common; among these errors, inaccurate descriptions of the P values and a lack of justification for the sample size were the most common. The observational studies were also of higher quality than the experimental studies.

       BACKGROUND: Conflicts of interest (CoI) can undermine trust in scientific publishing, yet empirical evidence on how often CoI lead to editorial action and how journals respond remains limited. This study aimed to characterise the frequency, patterns, and editorial handling of CoI‑related notices in the scholarly literature using an openly available, multidisciplinary dataset.
    METHODS: We conducted a descriptive cross‑sectional analysis of publicly available records from the Retraction Watch (RW) database, accessed via Crossref, from inception to 23 April 2026. All editorial notices in which CoI was explicitly mentioned as the sole or one of several stated reasons were included, encompassing retractions, corrections, expressions of concern, and reinstatements. For each record, we extracted article and notice dates, article type, scientific field, country of the corresponding author, number of authors and institutions, publisher, and all stated reasons for the notice. Data were analysed using descriptive statistics and bootstrap‑based confidence intervals.
    RESULTS: We identified 886 CoI‑related records (748 retractions, 39 corrections, 97 expressions of concern, and 2 reinstatements). CoI was the sole stated reason in 95 cases (10.7%), including 32 retractions, 11 corrections, and 52 expressions of concern; in the remaining notices, CoI most commonly co‑occurred with concerns such as compromised peer review, authorship or affiliation problems, journal or institutional investigations, and broader ethical violations. The median time from publication to editorial action was longest for expressions of concern and shortest for corrections, with wide variability across records and notice types. CoI‑related notices were concentrated in basic life, biomedical, and health sciences, and were unevenly distributed across high‑output countries and a small number of large publishers, particularly open‑access outlets. Most affected articles were original research papers with multi‑author, multi‑institution teams. Among articles with determinable author gender, both first and last authors were more often male than female, although these patterns were exploratory and lacked a baseline comparator.
    CONCLUSIONS: Editorial actions explicitly linked to CoI remain relatively uncommon compared with the broader volume of retractions and corrections, and CoI are rarely cited in isolation. The frequent co‑occurrence of CoI with other forms of misconduct or procedural problems suggests that undisclosed or poorly managed CoI often signal deeper weaknesses in disclosure practices, editorial oversight, and research governance rather than isolated administrative lapses. Strengthening CoI policies, transparency, verification mechanisms, and linked metadata systems may help detect problems earlier and support more consistent, graduated editorial responses.

       Background: Gender diversity in dermatology has increased over recent decades, with women now comprising a substantial portion of the workforce. However, it remains uncertain whether this shift is reflected in the composition of editorial boards, which play a key role in shaping dermatologic research. This study evaluated gender representation in the editorial leadership of dermatology journals in 2024, updating previous analyses and assessing progress toward gender equity.
    Objective: To review current trends of female participation as editors of dermatology journals.
    Methods: We analyzed the gender distribution of editorial boards across high-impact dermatology journals, categorizing members by role, including Editor-in-Chief, Deputy Editors, Associate Editors, and Section Editors.
    Results: Women comprised 35% of editorial board positions overall. Nonetheless, they held only 20% of editor-in-chief roles, 29% of deputy editor positions, and 34% of associate editor roles. Assistant and section editor positions had higher female representation (42 and 45%, respectively). Across the various editorial positions, women's representation ranged from 20 to 45%, with the majority having less than 40% female representation. Among the journals analyzed, women's representation ranged from 0 to 78%, with only 12 out of the 69 total journals at or above 50% female representation.
    Limitations: Our study did not assess factors influencing women's advancement, such as career preferences, leadership opportunities, or review participation rates.
    Conclusion: Despite incremental gains, women remain underrepresented in top editorial roles in dermatology journals. Continued efforts are needed to address systemic barriers, promote equity in journal and editorial leadership opportunities, and ensure fair recruitment and advancement practices.

       INTRODUCTION: As of 2004, sponsors of studies submitted under the Clinical Trials Regulation are required to confirm that the chosen gender distribution is appropriate for identifying gender-specific differences-unlike research studies submitted under professional regulations. One of the best-known examples illustrates why sex and gender should also be taken into account in these types of studies: in the case of heart attacks, warning symptoms differ between men and women, resulting in women being less likely to receive guideline-based treatment and more likely to die than men. The objective of the present study was to obtain an overview of how gender-related aspects are considered in medical research projects submitted to an ethics committee for review.
    METHODS: The analysis of 171 research proposals submitted to the Ethics Committee of the University of Marburg in 2021 was conducted using two self-developed scoring systems. The first score assessed the extent to which gender and diversity aspects were considered in the research proposal. The second score evaluated the availability and quality of existing knowledge of gender and diversity differences related to the topic of each proposal, as reflected in the medical literature. Literature searches were performed in PubMed (PM) using a dedicated search string and in the GENDERMED database (GM).
    RESULTS: A comparison of the two scoring systems indicates that in more than 70% of the research proposals that did not address gender or diversity aspects, the scientific literature nevertheless contained relevant evidence on gender- or diversity-related differences pertaining to the respective research topic.
    DISCUSSION: This result is noteworthy, as institutions that support science and research, such as the German Research Foundation (DFG), have long been recommending that applicants appropriately consider sex/gender and diversity in the planning stage of their research projects.
    CONCLUSION: Further studies are needed to determine which hurdles and barriers exist on the part of researchers. At key points within the research landscape, such as ethics committees, researchers could be made aware of these aspects at the planning stage and, where appropriate, be offered guidance.
