Bibliometric analysis of published articles on perinatal depression from 1920 to 2020.

AIM: To analyze the characteristics and trends in published research on perinatal depression between 1920 and 2020. METHODS: A search strategy in Web of Science identified all published literature on perinatal depression between January 1, 1920, and December 31, 2020. Output from Web of Science was used to analyze bibliometric information, and VOSViewer was used to visualize the networks of linkages between identified publications. RESULTS: There were 16,961 publications identified. Among these publications, there were 82,726 unique authors and 140 countries represented. The United States had the highest frequency of publications (44.6%). Most publications (69.8%) occurred between 2011 and 2020, with the first publication identified in 1928. There were 2197 unique journals identified, with over half publishing only one (n = 948, 43.2%) or two relevant publications (n = 314, 14.3%). Authors with the largest number of publications were Wisner (n = 115), Dennis (n = 95), and Murray (n = 92), while authors with the largest number of citations were Cox (n = 7225), Murray (n = 2755), and O'Hara (n = 2069). LIMITATIONS: While the Web of Science is a representative database identifying the greatest number of relevant articles, it may be unrepresentative of all published literature. CONCLUSION: This is the first study mapping publications on perinatal depression between 1920 and 2020. The rate of publication on perinatal depression has been steadily increasing in recent years with a wide variety of authors, countries, and journals represented. As the field continues to grow, trends may shift as early career researchers emerge and the importance of mental health in low-income countries is prioritized.

Pediatric hidradenitis suppurativa publication trends: 2012 to 2022.

There is a paucity of bibliometric data on pediatric-focused hidradenitis suppurativa (HS) publications. To better characterize research trends in pediatric HS and gaps in literature, we systematically searched PubMed between 2012 and 2022 for publications on pediatric HS and collected data on study design, topic, country, and level of evidence. Of 109 articles that met inclusion criteria, less than half (44/109, 40.4%) were high level of evidence studies; the most common study types were case reports/series (41/109, 37.6%) and cross-sectional studies (25/109, 22.9%), and the most common study topics were HS treatments (44/109, 40.4%), comorbidities (20/109, 18.3%), and clinical presentation (14/109, 12.8%). Although there has been expansion of the pediatric HS literature in recent years, our study highlights the need for larger prospective studies and trials to improve our ability to optimally manage pediatric HS patients and identify predictors of disease progression and treatment response.

Analysis of authorship trends in vascular surgery demonstrates a sticky surgical floor for women.

OBJECTIVE: Prior research in vascular surgery has identified significant gender disparities in leadership positions, but few data exist regarding gender disparities in vascular publications. This study aims to evaluate authorship trends by gender in the three highest impact factor vascular surgery journals. METHODS: In this bibliometric analysis, PubMed was searched for articles published in the European Journal of Vascular and Endovascular Surgery, the Journal of Vascular Surgery, and Annals of Vascular Surgery from 2015 to 2019. The web-based application Genderize used predictive algorithms to classify names of first and last authors as male or female. Statistical analyses regarding trends in authorship were performed using Stata16. RESULTS: A total of 6457 articles were analyzed, with first author gender predicted with >90% confidence in 83% (4889/5796) and last author gender in 88% (5078/5796). Overall, 25% (1223/4889) of articles had women first authors, and 10% (501/5078) had women last authors. From 2015 to 2019, there was a slight increase in the proportion of articles written by women first authors (P = .001), but no increase in the proportion of articles written by women last authors (P = .204). The proportion of articles written by women last authors was lower than the proportion of active women vascular surgeons in 2015 (8% of articles vs 11% of surgeons; P = .015), 2017 (9% of articles vs 13% of surgeons; P < .001), and 2019 (11% of articles vs 15% of practicing surgeons; P < .001). The average number of last-author publications was higher for men (2.35 ± 3.76) than for women (1.62 ± 1.88, P = .001). The proportion of unique authors who were women was less than the proportion of active women vascular surgeons in 2017 (10% unique authors vs 13% surgeons; P = .047), but not in 2015 (9% unique authors vs 11% surgeons; P = .192) or 2019 (13% unique authors vs 15% surgeons; P = .345). Notably, a woman last author was associated with 1.45 higher odds of having a woman first author (95% confidence interval, 1.17-1.79; P = .001). CONCLUSIONS: Over the past 5 years, there has been no significant increase in women last authors among top-tier journals in vascular surgery. Women remain under-represented as last authors in terms of proportion of published articles, but not in terms of proportion of unique authors. Nevertheless, women last authors are more likely to publish with women first authors, indicating the importance of women-led mentorship in achieving publication gender equity. Support for women surgeons through grants and promotions is essential not only for advancing last authorship gender equity, but for advancing junior faculty and trainee academic careers.

A cross-sectional study of participant recruitment rates in published phase III influenza therapeutic randomized controlled trials conducted in the clinical setting.

OBJECTIVE: A recent academic-government partnership demonstrated the feasibility of utilizing Emergency Departments (ED) as a primary site for subject enrollment in clinical trials and achieved high rates of recruitment in two U.S. EDs. Given the ongoing need to test new therapeutics for influenza and other emerging infections, we sought to describe the historical rates of participant recruitment into influenza Phase III therapeutic RCTs in various clinical venues, including EDs. STUDY DESIGN: A cross-sectional study was performed of influenza therapeutic Phase III RCTs published in PubMed, Embase, Scopus, and Clinicaltrials.gov from January 2000 to June 2019. MAIN OUTCOME: To estimate the weighted-average number of influenza-positive participants enrolled per site per season in influenza therapeutic RCT conducted in clinical settings, and to describe basic trial site characteristics. RESULTS: 47 (0.7%) of 7008 articles were included for review of which 43 of 47 (91%) included information regarding enrollment sites; of these, 2 (5%) recruited exclusively from EDs with the remainder recruiting from mixed clinical settings (inpatient, outpatient, and ED). The median enrollment per study was 326 (IQR: 110, 502.5) with a median of 11 sites per study (IQR: 2, 59.5). Included studies reported a median of 201 (IQR: 74, 344.5) confirmed influenza-positive participants per study. The pooled number of participants enrolled per site per season was 11 (95% CI: 10, 12). The pooled enrollment numbers per clinical site after excluding the two 'ED only recruitment' studies were less [10.7 (95% CI: 9.9, 11.6)] than the pooled enrollment numbers per clinical site for the two 'ED only recruitment' studies [89.5 (95% CI 89.2-89.27)]. CONCLUSION AND RELEVANCE: Published RCTs evaluating influenza therapeutics in clinical settings recruit participants from multiple sites but enroll relatively few participants, per site, per season. The few ED-based studies reported recruited more subjects per site per season. Untapped opportunities likely exist for EDs to participate and/or lead therapeutic RCTs for influenza or other emerging respiratory pathogens.

Laser procedures in the treatment of BPH: a bibliometric study.

PURPOSE: To perform a bibliometric analysis of lased-based BPH treatment publications and to obtain an understanding of the publication trends over time. MATERIALS AND METHODS: The Medline database was searched for articles in English language regarding laser-based BPH therapy up to 2018. Matching articles were assigned to at least one of the following categories: Ho:YAG, Tm:YAG, green light, diode, Nd:YAG laser and review articles. The laser categories were analysed using bibliometric procedures regarding citation rate, authors, country of origin and journal of publication. Moreover, the articles on laser BPH therapy included in the EAU, AUA and JUA guidelines were analysed to evaluate the most influential articles. RESULTS: In total, 982 articles were included: 317 articles were assigned to green light, 283 to Ho:YAG, 101 to Tm:YAG, 74 to Nd:YAG and 39 to diode lasers. The publication rate for Nd:YAG laser has declined, but continues to grow for Ho:YAG and Tm:YAG lasers. We found a positive correlation between number of authors and year of publication (R = 0.3, p < 0.001*). Articles on Ho:YAG lasers are cited the most (mean 23.0 ± 37.1). Asia has contributed the most articles. Mostly, countries with high health and research and development (R&D) expenditures influenced the guidelines regarding laser-based approaches. Yet, after adjustment of all search results to GDP, health and R&D expenditure, India and China were the most prolific countries. CONCLUSION: Laser-based approaches for BPH treatment are increasing but have not been implemented worldwide. Asia's contribution should be acknowledged. An inflationary trend regarding the number of authors per article is confirmed.

A bibliometric of publication trends in medical image segmentation: Quantitative and qualitative analysis.

PURPOSE: Medical images are important in diagnosing disease and treatment planning. Computer algorithms that describe anatomical structures that highlight regions of interest and remove unnecessary information are collectively known as medical image segmentation algorithms. The quality of these algorithms will directly affect the performance of the following processing steps. There are many studies about the algorithms of medical image segmentation and their applications, but none involved a bibliometric of medical image segmentation. METHODS: This bibliometric work investigated the academic publication trends in medical image segmentation technology. These data were collected from the Web of Science (WoS) Core Collection and the Scopus. In the quantitative analysis stage, important visual maps were produced to show publication trends from five different perspectives including annual publications, countries, top authors, publication sources, and keywords. In the qualitative analysis stage, the frequently used methods and research trends in the medical image segmentation field were analyzed from 49 publications with the top annual citation rates. RESULTS: The analysis results showed that the number of publications had increased rapidly by year. The top related countries include the Chinese mainland, the United States, and India. Most of these publications were conference papers, besides there are also some top journals. The research hotspot in this field was deep learning-based medical image segmentation algorithms based on keyword analysis. These publications were divided into three categories: reviews, segmentation algorithm publications, and other relevant publications. Among these three categories, segmentation algorithm publications occupied the vast majority, and deep learning neural network-based algorithm was the research hotspots and frontiers. CONCLUSIONS: Through this bibliometric research work, the research hotspot in the medical image segmentation field is uncovered and can point to future research in the field. It can be expected that more researchers will focus their work on deep learning neural network-based medical image segmentation.

Parasitological research in the molecular age.

New technological methods, such as rapidly developing molecular approaches, often provide new tools for scientific advances. However, these new tools are often not utilized equally across different research areas, possibly leading to disparities in progress between these areas. Here, we use empirical evidence from the scientific literature to test for potential discrepancies in the use of genetic tools to study parasitic vs non-parasitic organisms across three distinguishable molecular periods, the allozyme, nucleotide and genomics periods. Publications on parasites constitute only a fraction (<5%) of the total research output across all molecular periods and are dominated by medically relevant parasites (especially protists), particularly during the early phase of each period. Our analysis suggests an increasing complexity of topics and research questions being addressed with the development of more sophisticated molecular tools, with the research focus between the periods shifting from predominantly species discovery to broader theory-focused questions. We conclude that both new and older molecular methods offer powerful tools for research on parasites, including their diverse roles in ecosystems and their relevance as human pathogens. While older methods, such as barcoding approaches, will continue to feature in the molecular toolbox of parasitologists for years to come, we encourage parasitologists to be more responsive to new approaches that provide the tools to address broader questions.

Looking back, looking forward: forty years of the Journal of Behavioral Medicine.

The inception, development, and rise of the Journal of Behavioral Medicine (JOBM) has paralleled that of the field of behavioral medicine. Under the leadership of founding editor, W. Doyle Gentry, published its first issue in 1978. The subsequent 40 years have seen JOBM progress to the level of a top tier journal publishing inter-disciplinary work devoted to furthering understanding of physical health and illness through the theories and methodologies of behavioral science. In recent years, JOBM has become a prominent international platform for scientific communication in the field of behavioral medicine. The present article examines many of the important milestones JOBM has achieved and examines the scope and impact of the most highly cited papers in the journal's history. As Stephen Weiss and Gary Schwartz predicted 40 years ago, behavioral medicine is in a unique and powerful position to address a broad range of issues surrounding individual, community, and population health. It is the hope of the current editorial team that in the next 40 years the journal will facilitate a broadening of the clinical and public health contexts that the science and practice of behavioral medicine addresses and informs.

Recent trends in publications of US vascular surgery program directors.

Objective In order to examine the academic productivity of US vascular surgery program directors, the number of vascular publications listed in PubMed from 2001 to 2015 for US vascular surgery program directors was reviewed. We suggest that this can be used as a benchmark for academic productivity. Methods The names of the program directors were taken from the Accreditation Council for Graduate Medical Education (ACGME) website at two time points: December 2009 (Independent Programs) and December 2015 (Independent + Integrated). This was used to query PubMed, which listed 5196 publications: 3284 from 2001 to 2009 and 1912 from 2010 to 2015. Results There were 104 program directors (2001-2009) and 114 program directors (2010-2015) with average number of publications in PubMed per program director as 3.68/year (SD ± 2.31) and 2.80/year (SD ± 2.73), respectively ( P = .01). From 2001 to 2009, 1215 (37%) and in 2010 to 2015, 860 (45%) of the publications were from Journal of vascular surgery. The top third produced 67% and 69% of publications in the two time-points. No statistical difference was ascertained regionally: northeast, southeast, midwest and west ( P = .46). The numbers of publications/year decreased by 17% compared to first 10 years. From 2001 to 2009, there were no programs with no publications which increased to five and three with no Journal of Vascular Surgery publications which increased to 21 in 2010-2015. The independent and integrated program directors published average of 2.85 (SD ± 2.69) and 3.47 (SD ± 3.1) total publications; 1.25 (SD ± 1.4) and 3.47 (SD ± 1.7) Journal of Vascular Surgery papers/year, respectively ( P = .28, P = .23). Changes in the study subject were noted by percentage of total publications: endovascular lower extremity arterial (4.7% to 8.9%), Thoracic Endovascular Aortic Repair (TEVAR) (4.5% to 9.9%), Arterio-Venous (AV) access (0.0% to 3.0%), basic science (14.7% to 6.8%), open thoracic (3.0% to 0.6%). Conclusion There seems to be a significant decline in the number of publications over the last 15 years. Yet, the subject of the publications has progressed from Open to TEVAR with an increase in endovascular publications. However, basic science publications reduced by half.

Publication patterns in developmental psychology: Trends and social networks.

Interest in publication patterns has been steady. Journals have instituted policies in an effort to curb bias and provide globally representative research. This study aimed to examine if publication patterns were present in two developmental psychology journals. It also explored the social networks of prominent authors and the prevalence of informal author-editor relationships, searching for any potential power groups. Data were taken from empirical articles published between 2005 and 2014 in Child Development (CD) and The International Journal of Early Childhood (IJEC) data points were geographical authorship affiliation, informal author relationships as established by co-publishing, and connections to journal editors via identical affiliation. Results confirmed the previously established North American dominance in published research. In CD a strongly interlinked social network was identified between authors over the 10 years, with 15 chief influentialists binding groups of authors together. Results suggest that patterns are still present in published research in the realm of developmental psychology. To conclude, the potential implications of these patterns within developmental psychology are presented.

Possible Biases of Researchers' Attitudes Toward Video Games: Publication Trends Analysis of the Medical Literature (1980-2013).

BACKGROUND: The study of video games is expanding, and so is the debate regarding their possible positive and deleterious effects. As controversies continue, several researchers have expressed their concerns about substantial biases existing in the field, which might lead to the creation of a skewed picture, both in the professional and in the lay literature. However, no study has tried to examine this issue quantitatively. OBJECTIVE: The objective of our study was to examine possible systematic biases in the literature, by analyzing the publication trends of the medical and life sciences literature regarding video games. METHODS: We performed a complete and systematic PubMed search up to December 31, 2013. We assessed all 1927 articles deemed relevant for their attitude toward video games according to the focus, hypothesis, and authors' interpretation of the study results, using a 3-category outcome (positive, negative, and neutral). We assessed the prevalence of different attitudes for possible association with year of publication, location of researchers, academic discipline, methodological research, and centrality of the publishing journals. RESULTS: The attitude toward video games presented in publications varied by year of publication, location, academic discipline, and methodological research applied (P<.001 for all). Moreover, representation of different attitudes differed according to centrality of the journals, as measured by their impact factor (P<.001). CONCLUSIONS: The results suggest that context, whether scientific or social, is related to researchers' attitudes toward video games. Readers, both lay and professional, should weigh these contextual variables when interpreting studies' results, in light of the possible bias they carry. The results also support a need for a more balanced, open-minded approach toward video games, as it is likely that this complex phenomenon carries novel opportunities as well as new hazards.

Clarifying values, risk perceptions, and attitudes to resolve or avoid social conflicts in invasive species management.

Decision makers and researchers recognize the need to effectively confront the social dimensions and conflicts inherent to invasive species research and management. Yet, despite numerous contentious situations that have arisen, no systematic evaluation of the literature has examined the commonalities in the patterns and types of these emergent social issues. Using social and ecological keywords, we reviewed trends in the social dimensions of invasive species research and management and the sources and potential solutions to problems and conflicts that arise around invasive species. We integrated components of cognitive hierarchy theory and risk perceptions theory to provide a conceptual framework to identify, distinguish, and provide understanding of the driving factors underlying disputes associated with invasive species. In the ISI Web of Science database, we found 15,915 peer-reviewed publications on biological invasions, 124 of which included social dimensions of this phenomenon. Of these 124, 28 studies described specific contentious situations. Social approaches to biological invasions have emerged largely in the last decade and have focused on both environmental social sciences and resource management. Despite being distributed in a range of journals, these 124 articles were concentrated mostly in ecology and conservation-oriented outlets. We found that conflicts surrounding invasive species arose based largely on differences in value systems and to a lesser extent stakeholder and decision maker's risk perceptions. To confront or avoid such situations, we suggest integrating the plurality of environmental values into invasive species research and management via structured decision making techniques, which enhance effective risk communication that promotes trust and confidence between stakeholders and decision makers.

[Literature of so-called "clinical research": structure and trends, 1991-2010]. / A klinikainak nevezett kutatások szakirodalmának szerkezete és irányai, 1991-2010.

The authors studied trends and patterns in the literature of research labeled as clinical (i.e., having the word "clinical" in their title) in the period between 1991 and 2010. The main findings are: 1. The growth of the literature under study was somewhat stronger than that of the overall medical literature. 2. The dominance of the USA is strong but is challenged by some of the most rapidly developing countries (particularly in the Far-East region: China, Korea) in total production, and by the developed European countries in highly cited publications. The eminence of Italy is remarkable. 3. In comparing the medical fields, the most striking tendencies are the increase of oncology and the attenuation of internal medicine. Surgery is steadily growing in size but decreasing in its citation influence. 4. Word frequency studies support the ever growing weight of oncology and also of genetics. 5. Beyond the thematic changes, word frequency studies also reveal a substantial change in attitude: in the period under study more and more effort was made on emphasizing the usefulness, efficiency and risks of the results in contrast with the more descriptive, investigative approach of the past. The role of therapy is growing, the role of diagnostics is decreasing. The knowledge of these trends and patterns may orient health and science policy makers to cope appropriately with the ever changing world of clinical research.

Emerging global trends and development in forensic toxicology: A review.

This study conducts a comprehensive analysis of forensic toxicology research trends, publication patterns, author's contributions, and collaboration. Utilizing the Scopus database, we scrutinized 3259 articles across 348 journals spanning from 1975 to 2023. Analysis employed diverse software tools such as VOSviewer, RStudio, MS Excel, and MS Access to dissect various publication aspects. We observed a notable surge in publications post-2007, indicating heightened research interest. Leading contributors included the United States, Germany, and Italy, with Logan B.K. emerging as the most prolific author. Forensic Science International stood out as the primary journal, publishing 888 articles and accruing significant citations. Keyword co-occurrences such as "forensic toxicology," "forensic science," and "toxicology" underscored core thematic areas in the field. Moreover, extensive research collaboration, especially among Western nations in Europe, was evident. This study underscores the imperative for enhanced collaboration between developing and developed nations to foster further advancements in forensic science. Strengthened partnerships can catalyze innovation, facilitate knowledge dissemination, and address emerging challenges, thereby propelling the field of forensic toxicology toward new frontiers of discovery and application.

Sepsis Research Using Omics Technology in the European Union and the United Kingdom: Maps, Trends, and Future Implications.

High-throughput omics technologies have become valuable tools for systems science research and clinical management of sepsis. This article analyzes sepsis research using omics technologies in the European Union (EU) and the United Kingdom from 1990 to May 2023 using bibliometric data from the Web of Science database. Using VOSviewer for network analysis, we examined the distribution patterns, funding characteristics, and collaborations among the states, noting trends of convergence and divergence. The analysis included 2078 articles, revealing an increasing rate of publications on sepsis research using omics approaches. The United Kingdom's research output is notably high, contributing 28.3% of the total research from the EU and United Kingdom combined. Germany, France, the Netherlands, and Italy together account for 56.9% of the publications from the EU member states. The United States is the leading international collaborator, particularly with the United Kingdom, followed by Germany and France. The EU-15 countries have significantly more publication outputs in this domain with growing but limited inclusion of the newer members of the EU. We suggest that the role of EU member states and the United Kingdom in sepsis research using omics technologies can be advanced by facilitating high-value, technology-driven health research, fostering collaboration, convergence, and equity in global health and biomedical research.

A review of age estimation methods in non-avian reptiles by growth marks in hard tissues.

Age and growth-related data are basic biological parameters, essential in population ecology, evolution, and conservation biology. There is a growing body of published information on reptile demography derived from sclerochronology, a technique based on counting the growth layers deposited in bones (skeletochronology) and other hard body structures. Since the data are not always easily available, we compiled the existing published data, described the current status of knowledge, synthetized the conclusions of disparate studies, and identified patterns of research and information gaps, prioritizing the needs for future research. Our database includes the results of 468 published studies covering 236 reptile species from 41 families. These represent less than 2% of the total number of known extant species. Turtles and crocodiles are proportionally better studied, while snakes are the least examined group. The distribution of the research does not reflect conservation needs; we found an important geographic bias, with an overrepresentation of Northern temperate species. Only 23% of the studies checked the assumption of periodicity of growth marks deposition, and the method was found to be reliable or adequate in 79% of the cases. Overall, the data obtained through sclerochronology can be considered robust, especially if validation methods are employed, since the general goal is to characterize population parameters, trends, and dynamics, rather than determining the exact age of any specimen in particular.

Artificial intelligence and machine learning trends in kidney care.

BACKGROUND: The integration of artificial intelligence (AI) and machine learning (ML) in kidney care has seen a significant rise in recent years. This study specifically analyzed AI and ML research publications related to kidney care to identify leading authors, institutions, and countries in this area. It aimed to examine publication trends and patterns, and to explore the impact of collaborative efforts on citation metrics. METHODS: The study used the Science Citation Index Expanded (SCI-EXPANDED) of Clarivate Analytics Web of Science Core Collection to search for AI and machine learning publications related to nephrology from 1992 to 2021. The authors used quotation marks and Boolean operator "or" to search for keywords in the title, abstract, author keywords, and Keywords Plus. In addition, the 'front page' filter was applied. A total of 5425 documents were identified and analyzed. RESULTS: The results showed that articles represent 75% of the analyzed documents, with an average author to publications ratio of 7.4 and an average number of citations per publication in 2021 of 18. English articles had a higher citation rate than non-English articles. The USA dominated in all publication indicators, followed by China. Notably, the research also showed that collaborative efforts tend to result in higher citation rates. A significant portion of the publications were found in urology journals, emphasizing the broader scope of kidney care beyond traditional nephrology. CONCLUSIONS: The findings underscore the importance of AI and ML in enhancing kidney care, offering a roadmap for future research and implementation in this expanding field.

Bibliometric analysis of Naunyn-Schmiedeberg's Archives of Pharmacology (1947-1974).

Naunyn-Schmiedeberg's Archives of Pharmacology is the oldest pharmacological journal, founded in 1873. This bibliometric analysis examines the pivotal transformations within Naunyn-Schmiedeberg's Archives of Pharmacology from 1947 to 1974, identifying significant shifts from a national focus to a period of extensive internationalization and English-language adoption. Employing Python and Beautiful Soup for data extraction from SpringerLink, the study maps the journal's trajectory through post-World War II development, highlighting the decline in publication rates due to its initial emphasis on German-language articles predominantly from Germany. The transition towards English publications in the late 1960s is marked as a turning point, catalyzing an increase in global citations, publications, and recognition. This period witnesses the journal broadening its scientific horizon, with a notable emphasis on the cholinergic, adrenergic, and dopaminergic systems, reflecting their central role in the journal's scientific discourse and citation prominence. The analysis demonstrates how shifting to English for academic publishing played a crucial role in revitalizing the journal's impact and visibility on the international stage.

Ethnicity and gender trends of UK authors in The British Medical Journal and the Lancet over the past two decades: a comprehensive longitudinal analysis.

Background: While gender equity among academic authors has been extensively investigated, there is a significant gap in our understanding of racial/ethnic authorship trends, despite the recognition of barriers to authorship along both ethnic and gender lines. Leveraging the meta-data for all articles published in The British Medical Journal (The BMJ) and the Lancet and between 2002 and 2022 (inclusive), we explore demographic trends among UK academic medicine authors in two of the world's leading British medical journals. Methods: We systematically searched PubMed's MEDLINE for all articles published in The BMJ and Lancet between January 1st 2002 and December 31st 2022. Filtering for articles with a UK affiliation, we predicted gender using a publicly-validated name-to-gender dictionary, while data was analysed to explore and investigate ethnicity using the Consumer Data Research Centre's (CDRC) Ethnicity Estimator. Data was analysed to explore and investigate: (a) the proportion of female/male author publications, (b) the proportion of the various UK author ethnicity groups, and (c) the overlap/intersection between gender and ethnic identities among first and last authors. This comprehensive longitudinal analysis was conducted on 82,143 articles (51,209 from The BMJ and 30,934 from the Lancet) which represents >97% of all published articles between 2002 and 2022. As we sought to understand how academic authorship reflects the diversity of the UK population, we limited our analysis to first and last authors who had a UK affiliation and excluded "news" and "comments" pieces (16,736 articles for The BMJ and 4678 articles from the Lancet). The main outcome measures were the trends in first and last authorship demographics of academic medicine, focusing on the proportion of female/male authors, ethnicity and their intersectionality. Findings: Our findings show that, while women have made substantial headway towards equity among first and last authorship in The BMJ (peaking at 42% and 43%), they remain under-represented in the Lancet (35% and 27%). In both The BMJ and Lancet, Black authors have remained severely under-represented as both first and last authors (below 1% for most of the two decades), while Asian authors have increased proportionally to match their fraction in the general population (ranging from 2 to 10%). Interpretation: Analysis over the past two decades has shown that the gender author gap is decreasing quickly in The BMJ and Lancet. However, despite the two journals' growing focus on structural inequalities in medical academia, little progress has been made in rectifying the large gap between White British authors and other ethnic groups, especially Black authors. Without more awareness, diversity initiatives which have resulted in positive gains for White women do not seem to translate well for authors of colour. Funding: None.

Anxiety in bipolar disorder: A review of publication trends.

BACKGROUND: Although anxiety is highly prevalent in people with bipolar disorders and has deleterious impact on the course of the illness, past reviews have shown that many aspects of the topic remain under-researched. This scoping review aims to provide a comprehensive overview of the literature addressing anxiety in bipolar disorder (A-BD) between 2011 and 2020, assess if the interest in the topic has increased over the period and map the publication trends. METHODS: Three databases were systematically searched, and all articles were screened at the title/abstract and full text level based on inclusion and exclusion criteria. Of these, 1099 articles were included in the study. The annual number of articles on A-BD published between 2011 and 2020 was calculated and articles addressing it as a primary topic (n = 310) were classified into 4 categories and 11 subcategories to identify gaps in the knowledge. RESULTS: The results show no clear increase in the number of annual publications during the period and much of the available literature is of a descriptive nature. Less is known about the processes underlying the comorbidity and about treatment approaches. LIMITATIONS: Given the large scope of the research question, no quality assessment of the evidence was made. Only articles in English or French were considered. CONCLUSIONS: These results highlight the need to change the focus of research efforts to better understand and address this unique set of conditions in clinical settings.
