Novel single-nucleus transcriptomics unravels developmental and functionally controlled principles of mammalian neuromuscular junctions.

Prof Ohno's team (Ohkawara et al. 2023, current issue) underscored the dynamic and functional features that co-shape the embryonic and early post-natal development of mammalian neuromuscular junctions (NMJs) using single-nucleus transcriptomics which provides specific insights into the activities of individually studied nuclei and their functional characteristics. Unlike other single-nucleus transcriptomics studies, which tend to be limited to single developmental time points, this article provides novel views of the complex developmental and regulatory dynamics and embryonic cell type origins underscoring the formation of functioning mammalian NMJs by combining this transcriptomic approach with interference tests in cultured C2C12 myotubes. This reveals intriguing novel links between the particular nicotinic acetylcholine receptor genes (nAChR) and regulator transcripts thereof and enables outlining the sequential development of functioning NMJs along embryogenesis and soon after delivery. Specifically, the timewise and cell type origins of the studied nuclei emerged as essential for NMJ neurogenesis and inter-cellular transfer of specific regulators has been indicated. Breaking the barriers between distinct research subdisciplines, this study opens new neurochemistry research directions that recombine developmental, regulatory, and functional transcriptomics in NMJ-including tissues. Moreover, these findings may facilitate tests of diverse pharmaceutical and therapeutic modulators of neuromuscular functioning in health and disease, assisting the translational research progress in treating devastating neuromuscular states such as in amyotrophic lateral sclerosis, myasthenia gravis or individuals poisoned occupationally or otherwise with anticholinesterase inhibitors.

Protecting and promoting editorial independence.

We argue that editorial independence, through robust practice of publication ethics and research integrity, promotes good science and prevents bad science. We elucidate the concept of research integrity, and then discuss the dimensions of editorial independence. Best practice guidelines exist, but compliance with these guidelines varies. Therefore, we make recommendations for protecting and strengthening editorial independence.

Analyzing the composition of the editorial boards in high-impact medical ethics journals: a survey study.

BACKGROUND: The underrepresentation of scholarly works from low- and middle-income countries (LMICs) in academic literature is a documented concern, attributed partly to editorial biases. This trend, prevalent across various disciplines, has been less explored in the context of medical ethics journals. This study aimed to examine the composition of editorial board members (EBM) in high-impact medical ethics journals and to evaluate the extent of international diversity within these editorial teams. METHODS: This study incorporated an analysis of 16 high-impact medical ethics journals. Information regarding the EBM of these journals was systematically gathered and categorized based on the World Bank's country income classifications. An in-depth examination of the editorial board compositions was then conducted. RESULTS: The study identified 669 EBM across the selected journals. A predominant 89.84% (601) of these members were from high-income countries (HICs), with upper-middle-income countries contributing 7.47% (50) and lower-middle-income countries 2.69% (18). No EBM were associated with low-income countries. A regional breakdown indicated that North America was the most represented area, accounting for 48.88% (327), followed by Europe & Central Asia (27.50%, 184), East Asia & Pacific (13.45%, 90), Latin America & Caribbean (4.63%, 31), Sub-Saharan Africa (4.19%, 28), Middle East & North Africa (0.75%, 5), and South Asia (0.60%, 4). In total, these EBMs hailed from 46 different countries, with the United States representing the largest proportion (43.80%, 293), followed by the United Kingdom (13.15%, 88), Australia (7.92%, 53), Germany (6.73%, 45), and Canada (5.08%, 34). CONCLUSIONS: There is a significant lack of international representation within the EBM of high-impact medical ethics journals. The majority of editors in this field are affiliated with HICs, leading to a severe underrepresentation of LMICs within the editorial boards.

Consolidated Reporting Guidelines for Prognostic and Diagnostic Machine Learning Models (CREMLS).

The number of papers presenting machine learning (ML) models that are being submitted to and published in the Journal of Medical Internet Research and other JMIR Publications journals has steadily increased. Editors and peer reviewers involved in the review process for such manuscripts often go through multiple review cycles to enhance the quality and completeness of reporting. The use of reporting guidelines or checklists can help ensure consistency in the quality of submitted (and published) scientific manuscripts and, for example, avoid instances of missing information. In this Editorial, the editors of JMIR Publications journals discuss the general JMIR Publications policy regarding authors' application of reporting guidelines and specifically focus on the reporting of ML studies in JMIR Publications journals, using the Consolidated Reporting of Machine Learning Studies (CREMLS) guidelines, with an example of how authors and other journals could use the CREMLS checklist to ensure transparency and rigor in reporting.

Evaluating industry payments to editorial board members of otolaryngology journals.

OBJECTIVE: To evaluate the extent of payments from medical device and pharmaceutical companies to editorial board members of leading otolaryngology journals. METHODS: Editorial board members of the top 10 otolaryngology journals from Google Scholar rankings were identified in this cross-sectional study. Payments between 2017 and 2022 were identified via the Open Payments Database from the Centers for Medicare and Medicaid Services. All payment data was adjusted for inflation in 2022 US dollars. Descriptive analyses were performed and journal websites were evaluated for individual editor disclosures. RESULTS: Out of 581 board members, 306 (53 %) received industry payments between 2017 and 2022, median journal percentage 55 % (interquartile range: 26.5 %-73.5 %). A sum of $45.8 million was paid out between 2017 and 2022, comprising $32.0 million in associated research funding, $1.2 million in research payments, $1.4 million in ownership and investment interests, and $11.2 million in general payments. The largest general payments were made out for "services other than consulting and speaking" ($3.9 million), "consulting" ($3.8 million), "travel and lodging" ($0.99 million), "education" ($0.87 million), "royalty or license" ($0.56 million), and "food and beverage" ($0.55 million). Individual editor disclosures were only available for International Forum of Allergy and Rhinology (9 % of all included editors). CONCLUSIONS: Industry payments to editors of otolaryngology journals are not uncommon. We highlight the need for improved reporting of individual editor disclosures for transparency to journal readers and for minimizing biased editorial decisions.

Data Policy Finder: an easily integratable tool connecting data librarians with researchers to navigate publication requirements.

The Data Policy Finder is a searchable database containing librarian-curated information, links, direct quotes from relevant policy sections, and notes to help the researcher search, verify, and plan for their publication data requirements. The Memorial Sloan Kettering Cancer Center Library launched this new resource to help researchers navigate the ever-growing, and widely varying body of publisher policies regarding data, code, and other supplemental materials. The project team designed this resource to encourage growth and collaboration with other librarians and information professionals facing similar challenges supporting their research communities. This resource creates another access point for researchers to connect with data management services and, as an open-source tool, it can be integrated into the workflows and support services of other libraries.

Preclinical and clinical imaging techniques as pathophysiological biomarkers - A preface to the special issue "Brain Imaging".

Molecular imaging techniques have become important tools to characterize and measure biological processes at the cellular and molecular levels. Nowadays, molecular imaging techniques are widely used in preclinical and clinical studies to assess the molecular dynamics under physiological conditions and during pathological processes. This special issue on Brain Imaging (https://onlinelibrary.wiley.com/doi/toc/10.1111/[ISSN]1471-4159.brain-imaging) will highlight some of the recent advances in developing new tools and applying molecular imaging techniques to understand biomarker dynamics in health and diseases.

Honoring the gift: The transformative potential of transplant-declined human organs.

For decades, transplantation has been a life-saving treatment for those fortunate enough to gain access. Nevertheless, many patients die waiting for an organ and countless more never make it onto the waitlist because of a shortage of donor organs. Concurrently, thousands of donated organs are declined for transplant each year because of concerns about poor outcomes post-transplant. The decline of any donated organ-even if medically justified-is tragic for both the donor family and potential recipients. In this Personal Viewpoint, we discuss the need for a new mindset in how we honor the gift of organ donation. We believe that the use of transplant-declined human organs in translational research has the potential to hasten breakthrough discoveries in a multitude of scientific and medical areas. More importantly, such breakthroughs will allow us to properly value every donated organ. We further discuss the many practical challenges that such research presents and offer some possible solutions based on experiences in our own research laboratories. Finally, we share our perspective on what we believe are the necessary next steps to ensure a future where every donated organ realizes its full potential to impact the lives of current and future patients.

Information design to support growth, quality, and equity of the US transplant system.

The Organ Procurement and Transplantation Network, an arm of the Health Resources and Services Administration, has a contract with the United Network for Organ Sharing since 1986 to provide central oversight of organ donation and transplants in the United States. The United Network for Organ Sharing has recently come under scrutiny, prompting a review by the National Academies of Sciences, Engineering, and Medicine as summarized in its recent report and also by the US Senate Finance Committee. The national news services have opined about organ donation ethics, access to transplantation particularly for medically underserved populations, and management of organ transplantation data. These critiques raise important concerns that deserve our best response as a transplant community. Broadly, we suggest that the data management approach of the Organ Procurement and Transplantation Network be replaced with a patient-centric omnichannel network in which all donor and recipient data exist in a single longitudinal record that can be used by all applications. A more comprehensive and standardized approach to donor data collection would drive quality improvement across organ procurement organizations and help address inequities in transplantation. Finally, a substantial increase in organ donation would be prompted by considering organ donors as a public health resource, meriting transparent publicly available data collection with respect to organ donor referral, screening, and management.

Race/Ethnicity and Gender Representation in Hematology and Oncology Editorial Boards: What is the State of Diversity?

INTRODUCTION: Women and underrepresented groups in medicine hold few academic leadership positions in the field of hematology/oncology. In this study, we assessed gender and race/ethnicity representation in editorial board positions in hematology/oncology journals. MATERIALS AND METHODS: Editorial leadership board members from 60 major journals in hematology and oncology were reviewed; 54 journals were included in the final analysis. Gender and race/ethnicity were determined based on publicly available data for Editor-in-Chief (EiC) and Second-in-Command (SiC) (including deputy, senior, or associate editors). Descriptive statistics and chi-squared were estimated. In the second phase of the study, editors were emailed a 4-item survey to self-identify their demographics. RESULTS: Out of 793 editorial board members, 72.6% were men and 27.4% were women. Editorial leadership were non-Hispanic white (71.1%) with Asian editorial board members representing the second largest majority at 22.5%. Women comprised only 15.9% of the EiC positions (90% White and 10% Asian). Women were about half as likely to be in the EiC position compared with men [pOR 0.47 (95% CI, 0.23-0.95, P = .03)]. Women represented 28.3% of SiC editorial positions. Surgical oncology had the lowest female representation at 2.3%. CONCLUSION: Women and minorities are significantly underrepresented in leadership roles on Editorial Boards in hematology/oncology journals. Importantly, the representation of minority women physicians in EiC positions is at an inexorable zero.

Analysis of gender representation on transfusion medicine journal editorial boards: Comparison between 2019 and 2022.

BACKGROUND AND OBJECTIVES: A 2019 study highlighted significant gender inequities among blood banking and transfusion medicine (BBTM) journal editorial boards. We sought to assess if the representation of women has improved in the intervening 3 years. MATERIALS AND METHODS: We analysed the gender composition of nine BBTM journal editorial boards as of 13 September 2022, including the seven journals studied in 2019. We compared this to the proportion of females (term used by authors) on seven BBTM journal editorial boards in 2019 to assess change in the editorial board composition. We also assessed gender composition by editorial position (editor-in-chief [EIC], associate/assistant/titled editors and editorial board members). RESULTS: Nine BBTM journals have a total of 398 editorial positions and comprise significantly more men than women (68.8%, 274/398 vs. 31.2%, 124/398; p < 0.001). Among the seven journals analysed in 2019, the proportion of women on these seven editorial boards has remained unchanged (2019: 30.1%, 81/269 vs. 2022: 31.9%, 103/323; p = 0.66) despite the addition of 54 editorial positions. CONCLUSION: Women remain inequitably represented on journal editorial boards among all journal editorial positions. Although advocacy efforts are increasing, there has been limited improvement in gender equity in 3 years, despite a 20% increase in editorial positions.

Completeness of reporting in abstracts of randomized controlled trials assessing interventional radiology for liver disease.

PURPOSE: To assess the completeness of reporting in abstracts of published randomized controlled trials (RCTs) assessing interventional radiology (IR) for liver disease; to assess whether publication of the 2017 CONSORT update for nonpharmacological treatments (NPT) resulted in changes in abstract reporting; and to identify factors associated with better reporting. MATERIAL AND METHODS: MEDLINE and Embase were searched to identify RCTs of IR for liver disease (January 2015-September 2020). Two reviewers assessed the completeness of abstract reporting according to the CONSORT-NPT-2017-update. The primary outcome was the mean number of CONSORT items completely reported among 10 items reported in <50% of the abstracts published in 2015. A time series analysis assessed the evolution trend over time. A multivariate regression model was used to identify factors associated with better reporting. RESULTS: A total of 107 abstracts of RCTs published in 61 journals were included. Overall, 74% (45/61) of journals endorsed the main CONSORT guidelines, of which 60% (27/45) had a policy to implement them. The mean number of primary outcome items completely reported increased by 0.19 over the study period. The publication of the CONSORT-NPT update did not lead to an increase in the trend of items reported (increase of 0.04 items/month before vs. 0.02 after, P=0.41). Factors associated with more complete reporting were impact factor (OR=1.13; 95%CI:1.07-1.18) and endorsement of CONSORT with an implementation policy (OR=8.29; 95%CI:2.04-33.65). CONCLUSION: Completeness of reporting is incomplete in abstracts of trials of IR liver disease and did not improve after publication of the CONSORT-NPT-2017 update with abstract guidance.

Gender inequality among the editorial boards of periodontology and implantology journals.

OBJECTIVES: The aim of the present study was to investigate gender composition of the editorial board members of the journals in the field of periodontology and implantology. MATERIALS AND METHODS: A rigorous search was performed through Web of Science database to identify journals, scoping on the periodontology and implantology research fields. Data on journal's demographic information, gender of the editorial board members were gathered from the journals fulfilling the predefined inclusion/exclusion criteria. Variables including journal impact factor and quartiles were extracted as well. RESULTS: The proportion of women in the editorial team in periodontology journals was 27.3%, whereas it was almost 19% in implantology journals. As for editorial leadership, these ratios were 22.1% and 19.8%, respectively. There were significantly less women than men in editor-in-chief position in periodontology journals (p = 0.042). Journal metrics had no impact on the gender distribution of editor-in-chief positions in both fields. CONCLUSIONS: Women seem to be under-represented as editorial leaders or board members in journals of periodontology and implantology. The proportion of women in periodontology journals has increased in the last decade; however, there is still a clear need for further increase to have a gender balance.

Gender concordance and publication productivity within Neurosurgical Focus: a 10-year review (2013-2022).

OBJECTIVE: The "leaky academic pipeline" describes how female representation in leadership positions has remained stagnant despite an increase in the number of female trainees. Female mentorship to female mentees, and female role models at higher academic positions have been shown to positively influence academic productivity. To the authors' knowledge, the impact of female editorial board representation on authorship trends in neurosurgical journals remains undescribed. This study aimed to analyze trends in the representation of female topic editors and its impact on female authorship within Neurosurgical Focus over a 10-year period. METHODS: Publicly available data were collected from the journal's website, inclusive from January 2013 to December 2022. The articles were grouped into technical and nontechnical themes based on their relevance to specific technical details regarding surgical techniques. Female gender-concordant publications were defined as publications having a female first author (or co-first author) and a female senior author. Linear regression analysis determined trends in publishing. Odds ratios and 95% CIs were calculated using logistic regression analysis. Pearson correlation and cross-correlation analyses were used to examine each pairwise comparison of time series. The statistical significance of associations was evaluated using t-tests and chi-square and Fisher's exact tests. RESULTS: The number of female topic editors and gender-concordant authors increased over time (p < 0.05). Women accounted for ≥ 50% of the topic editors on nontechnical themes relevant to education and gender diversity. Having a female senior author was associated with higher publication productivity for original research and review articles among female authors (OR 13.73, 95% CI 1.75-394.31; p < 0.05). Female authors had higher odds of publishing editorials with a female topic editor (OR 3.81, 95% CI 1.37-11.02; p < 0.01). Publications with female first and senior authors were significantly more likely to have female topic editors (OR 4.05, 95% CI 1.38-12.92; p < 0.01). A positive association was observed between female senior authors and female topic editors at lag -8, with a correlation coefficient of 0.19 (p = 0.03). CONCLUSIONS: Female attending-to-female trainee mentorship and female representation among editorial boards play a crucial role in enhancing academic productivity among women. Efforts to sustain academic productivity during the early-career period would presumably help increase female representation in neurosurgery.

Best Practices for Using AI Tools as an Author, Peer Reviewer, or Editor.

The ethics of generative artificial intelligence (AI) use in scientific manuscript content creation has become a serious matter of concern in the scientific publishing community. Generative AI has computationally become capable of elaborating research questions; refining programming code; generating text in scientific language; and generating images, graphics, or figures. However, this technology should be used with caution. In this editorial, we outline the current state of editorial policies on generative AI or chatbot use in authorship, peer review, and editorial processing of scientific and scholarly manuscripts. Additionally, we provide JMIR Publications' editorial policies on these issues. We further detail JMIR Publications' approach to the applications of AI in the editorial process for manuscripts in review in a JMIR Publications journal.

Choosing the appropriate measure of central tendency: mean, median, or mode?

Mean, median, and mode are among the most basic and consistently used measures of central tendency in statistical analysis and are crucial for simplifying data sets to a single value. However, there is a lack of understanding of when to use each metric and how various factors can impact these values. The aim of this article is to clarify some of the confusion related to each measure and explain how to select the appropriate metric for a given data set. The authors present this work as an educational resource, ensuring that these common statistical concepts are better understood throughout the Orthopedic research community.
