Publishing original peer-reviewed research is essential for advancement through all career stages. Fewer women than men hold senior-level positions in academic medicine and, therefore, examining publication trends relative to gender is important. The goal of this study was to examine and compare publication trends in The Journal of Bone and Joint Surgery (JBJS) and The Bone and Joint Journal (BJJ) with a particular emphasis on trends regarding author gender. Data was collected and analyzed for manuscripts published in JBJS and BJJ over the past 30 years. For manuscripts published in 1986, 1996, 2006, and 2016, we recorded the numbers of authors, manuscript pages, references, collaborating institutions, the position in the byline of the corresponding author, the country of the corresponding author, and the names of the first and corresponding author. We also calculated the normalized number of citations and corresponding author position. The number of authors, institutions, and countries collaborating on manuscripts published in both JBJS and BJJ increased over time. JBJS published more manuscripts from North America and BJJ published more manuscripts from Europe. In both journals, the percentage of women as first and/or corresponding author increased over time. Trends over the past 30 years have shown increased collaborations with greater citations in manuscripts published in JBJS and BJJ. In the same time period, both journals demonstrated a rise in the percentage of manuscripts with women first and/or corresponding authors, suggesting a decrease in the gender gap.

Publication and authorship are important in academia for career advancement, obtaining grants, and improved patient care. There has been a recent interest in bibliometric changes over time, especially regarding the gender gap. The purpose of this study was to explore bibliometric changes in the musculoskeletal literature. Bibliometric variables (number of authors, institutions, countries, pages, references, corresponding author position, author gender, geographic region of origin, and editorial board makeup) were analyzed for 5 basic science and 12 clinically oriented musculoskeletal journals from 1985 through 2016. Statistical analyses comprised bivariate analyses, multifactorial ANOVAs, and logistic regression analyses. A p  < 0.005 was considered significant. Nearly, all variables increased over time. Asia had the highest number of authors and corresponding author positions, Australia/New Zealand the highest number of institutions and references, North America the highest number of pages, and Europe the highest number of countries. Those with a female first author had more authors, institutions, countries, references, and pages. Likewise, those with a female corresponding author had more authors, institutions, countries, references, and pages. Single-authored manuscripts decreased over time. The percentage of female first authors rose from 10.8% in 1985–1987 to 23.7% in 2015–2016. There were more female 1st authors in the basic science journals compared to the clinical journals (33.2% vs. 12.7%). Single-authored manuscripts were more likely to be written by males (5.1 vs. 2.4%) and decreased over time. The many differences by geographic region of origin likely reflect different socio/cultural attitudes regarding academia and research, as well as the gender composition of the disciplines by geographic region. Overall, there has been an increase in the number of female 1st and corresponding authors, editorial board members, and chief editors, indicating a slow but progressive narrowing of the gender gap.

Abstract Purpose This study aimed to evaluate both publication and authorship characteristics in Knee Surgery, Sports Traumatology, Arthroscopy journal (KSSTA) regarding knee arthroplasty over the past 15 years. Methods PubMed was searched for articles published in KSSTA between January 1, 2006, and December 31st, 2020, utilising the search term ‘knee arthroplasty’. 1288 articles met the inclusion criteria. The articles were evaluated using the following criteria: type of article, type of study, main topic and special topic, use of patient-reported outcome scores, number of references and citations, level of evidence (LOE), number of authors, gender of the first author and continent of origin. Three time intervals were compared: 2006–2010, 2011–2015 and 2016–2020. Results Between 2016 and 2020, publications peaked at 670 articles (52%) compared with 465 (36%) published between 2011 and 2016 and 153 articles (12%) between 2006 and 2010. While percentage of reviews (2006–2010: 0% vs. 2011–2015: 5% vs. 2016–2020: 5%) and meta-analyses (1% vs. 6% vs. 5%) increased, fewer case reports were published (13% vs. 3% vs. 1%) (p < 0.001). Interest in navigation and computer-assisted surgery decreased, whereas interest in perioperative management, robotic and individualized surgery increased over time (p < 0.001). There was an increasing number of references [26 (2–73) vs. 30 (2–158) vs. 31 (1–143), p < 0.001] while number of citations decreased [30 (0–188) vs. 22 (0–264) vs. 6 (0–106), p < 0.001]. LOE showed no significant changes (p = 0.439). The number of authors increased between each time interval (p < 0.001), while the percentage of female authors was comparable between first and last interval (p = 0.252). Europe published significantly fewer articles over time (56% vs. 47% vs. 52%), whereas the number of articles from Asia increased (35% vs. 45% vs. 37%, p = 0.005). Conclusion Increasing interest in the field of knee arthroplasty-related surgery arose within the last 15 years in KSSTA. The investigated topics showed a significant trend towards the latest techniques at each time interval. With rising number of authors, the part of female first authors also increased—but not significantly. Furthermore, publishing characteristics showed an increasing number of publications from Asia and a slightly decreasing number in Europe. Level of evidence IV.

OBJECTIVE Scientific productivity, as assessed by publication volume, is a common metric by which the academic neurosurgical field assesses its members. The number of authors per peer-reviewed article has been observed to increase over time across a broad range of medical specialties. This study provides an update to this trend in the neurosurgical literature. METHODS All publications from January 1, 1980, to April 30, 2020, were queried from four neurosurgical journals: Neurosurgery, Journal of Neurosurgery (JNS), JNS: Pediatrics, and JNS: Spine. Publication information was acquired from the National Center for Biotechnology Information Entrez database and reconciled with the Scopus database. Publication type was limited to articles and excluded editorials, letters, and reviews. The number of authors and affiliation counts were determined based on structured abstract fields provided in the two databases. RESULTS Between January 1, 1980, and April 30, 2020, the overall increase in author count for the four neurosurgical journals was 0.12 to 0.18 authors per year (p < 0.001). For Neurosurgery, the mean (SD) author count increased from 2.81 (1.4) in 1980–1985 to 7.97 (4.92) in 2016–2020 (p < 0.001). For the JNS, the mean (SD) author count increased from 2.82 (1.04) in 1980–1985 to 7.6 (3.65) in 2016–2020 (p < 0.001). The percentage of articles with more than 10 authors increased from 0.2% to 22.3% in Neurosurgery and from 1.9% to 17.5% in JNS. Only 28% of the author count variation was explained by an increasing number of institutional or departmental affiliations. CONCLUSIONS Author counts for peer-reviewed articles in neurosurgical academic journals have increased significantly during the past 4 decades, with large increases in the numbers of articles with more than 10 authors in the past 5 years. A total of 28% of the variation in this increase can be explained by an increase in multiinstitutional or multidepartmental studies.

Abstract Purpose: Acute myeloid leukemia (AML) is treated with conventional induction chemotherapy shortly after diagnosis in most patients less than or equal to 65 years old, most commonly combining infusional cytarabine with an anthracycline. Fatalities from infectious or bleeding complications related to cytopenias within 30 days of diagnosis (known as early death or treatment-related mortality) are routinely reported in these patients. Recent data from patients treated on clinical trials suggested a decline in the early death rate over the past two decades. It is unknown if a similar improvement has been observed in the general population. Methods: We examined the 30-day mortality and overall survival (OS) in a large population-based series of 9,380 AML patients reported to the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program. Included patients were diagnosed with AML between 1973 and 2010, were between the ages of 18 and 65 at diagnosis, and were treated with chemotherapy. We stratified patients by age and geographic location at diagnosis. Results: We observed a significant improvement in median OS from 6 months (95% CI 5-7) in 1973-1977 to 23 months (95% CI 16-20) in 2008-2010 (p < 0.001). During the same study period, the 30-day mortality rate declined from 18.7% among patients diagnosed in 1973-1977 (95% CI 16.4-21.2%) to 5.8% for those diagnosed in 2008-2010 (95% CI 4.5-7.6%) (p < 0.001). Weighted linear regression analysis revealed a strong linear trend in the 30-day mortality rate (R2 = 0.78), with an average annual decrease in the early death rate of 0.4% per year throughout the study period (β = 0.3755; Figure 1). When analyzed by age, the largest absolute improvements were noted in older patients (approximately 15% absolute decrease in 30-day mortality for patients aged 51-65 over study period). Though location at diagnosis significantly influenced 30-day mortality in 1973-1977, these differences in early death rate were no longer evident in the most recent time period (2008-2010). The patient characteristics remained stable over time with a median age at AML diagnosis of 50. Conclusion: Over the past four decades, significant improvements in median OS and 30-day mortality have occurred in our large cohort of younger patients (less than or equal to 65 years) with newly diagnosed AML undergoing chemotherapy. The largest improvements over time were noted in the oldest age group and in regions with intermediate to high early mortality in the earliest time period (1973-1977). The decrease in 30-day mortality appears to partially account for the increase in median OS observed over the past 4 decades. These data suggest that risk of early mortality has decreased and should not prevent younger patients with AML from receiving aggressive initial treatment modalities.

The purpose of this study was to provide 158 Open-Access Magazine Guides, 158 of which were found in the magazines covered by the Directory of Open Access Journal (DOAJ; from the beginning until the end of 2016) subjects; number of authors; number of citations; distribution of keywords; and distribution of magazines by country, author and citations. The authors of the most cited articles, the number of citations and years, the number of citations the authors have taken on a country basis, and page numbers and bibliographic numbers are examined. It is believed that in the current literature there is only one study on instructional design and it is necessary and important because of its contribution to the field. The fact that the articles published in the electronic magazines published in the DOAJ Open Access Guide used the term ‘Instructional Design’ in the keywords to reach the relevant articles constitutes the limitation of this study. This research is a quantitative study in the screening model because it is a research approach that identifies the situation that exists in the past and the present. Content analysis was done because the articles were examined in terms of content. The titles were searched, and the obtained data were uploaded to the spreadsheet program and the tables were created. The data were analysed by interpreting the tables by calculating the frequencies and percentages. Keywords: Citation analysis, DOAJ, instructional design, open access.

Abstract Background: Recent literature points to a decline over time in adolescent mental well-being but results are inconsistent and rely mainly on data from Western societies. This study investigates time trends in adolescent mental well-being (psychological and somatic complaints, life satisfaction) among Czech adolescents and explores whether these time trends are moderated by gender, age and socio-economic status. Methods: Nationally representative data from 29,378 Czech adolescents (50.8% girls, M age = 13.43; SD age = 1.65) across five Health Behaviour in School-aged Children (HBSC) surveys (2002, 2006, 2010, 2014, and 2018) were included in the analyses. Hierarchical regression models estimated national trends in adolescent mental well-being. We also tested whether these trends vary between girls and boys, adolescents of different age and from different socio-economic backgrounds. Results: Across the quadrennial surveys from 2002 to 2018, an increase in the psychological complaints was observed. Life satisfaction decreased over time up to 2014 only, whereas somatic symptoms increased until 2010, followed by a decline in 2014 and 2018. Girls, older adolescents and those from low family affluence reported poorer mental well-being outcomes. Gender gap increased over time for psychological complaints and life satisfaction. Socio-economic inequalities gap in adolescent mental well-being remained stable over the investigated timeframe. Conclusions: Our findings do not provide evidence for substantial temporal changes in mental well-being among adolescents in Czechia. Yet, only the increase in psychological complaints has been consistent which is an indicator of a decline over time in adolescent mental well-being. Furthermore, the gender gap in reporting psychological complaints and life satisfaction increased over time, whereas the age and socio-economic differences remained relatively stable. This calls for the attention of public health professionals and policy makers from Czechia.

Abstract Background and Aims The ESPN/ERA-EDTA Registry includes data on children with end-stage kidney disease receiving renal replacement therapy (RRT) in Europe for 10 consecutive years. We examined time trends in incidence, prevalence and patient survival for paediatric RRT in Europe. Method We included all children aged &lt; 15 years starting RRT in 22 European countries from 2007 to 2016. General population statistics were derived from Eurostat. Incidence and prevalence were expressed per million age related population (pmarp) and time trends were studied with Joinpoint regression. We analyzed patient survival using Cox regression. Results The incidence of children commencing RRT &lt; 15 years remained stable over the past ten years, varying between 5.5 pmarp to 6.5 pmarp. The incidence by treatment modality did not change over time: 2.0 to 3.0 pmarp for haemodialysis (HD) and peritoneal dialysis (PD) and 1.0 pmarp for transplantation. Overall prevalence rose by 2% annually (95% CI: 1.5-2.3%) from 29.5 pmarp in 2007 to 35.6 pmarp in 2016. The increase in prevalence was observed in all age categories, but was strongest among children older than 5 years at RRT initiation. The prevalence of patients on all treatment modalities increased during the study period: from 4.5 to 5.4 pmarp for HD, from 4.9 pmarp to 6.0 pmarp for PD and from 19.6 to 23.9 pmarp for transplantation (Figure). Four-year adjusted patient survival on RRT was around 96% and similar for those initiating from 2007-2009 and from 2010-2012 (adjusted HR: 0.97, 95% CI: 0.69-1.36). Conclusion Over the past decade we found a stable incidence and an increasing prevalence of European children on RRT. Four-year patient survival was good, and did not change over time. These data are important to inform patients and healthcare providers and to aid health policy makers on future resource planning of pediatric RRT in Europe.

Context New therapeutic strategies have developed for the management of acromegaly over recent decades. Whether this has improved mortality has not been fully elucidated. Objective The primary aim was to investigate mortality in a nationwide unselected cohort of patients with acromegaly. Secondary analyses included time trends in mortality and treatment patterns. Design A total of 1089 patients with acromegaly were identified in Swedish National Health Registries between 1987 and 2013. To analyse time trends, the cohort was divided into three periods (1987–1995, 1996–2004 and 2005–2013) based on the year of diagnosis. Main outcome measures Using the Swedish population as reference, standardized mortality ratios (SMRs) were calculated with 95% confidence intervals (CIs). Results Overall SMR was 2.79 (95% CI: 2.43–3.15) with 232 observed and 83 expected deaths. Mortality was mainly related to circulatory diseases (SMR: 2.95, 95% CI: 2.35–3.55), including ischemic heart disease (2.00, 1.35–2.66) and cerebrovascular disease (3.99, 2.42–5.55) and malignancy (1.76, 1.27–2.26). Mortality decreased over time, with an SMR of 3.45 (2.87–4.02) and 1.86 (1.04–2.67) during the first and last time period, respectively (P = .015). During the same time periods, the frequency of pituitary surgery increased from 58% to 72% (P < 0.001) and the prevalence of hypopituitarism decreased from 41% to 23% (P < 0.001). Conclusions Excess mortality was found in this nationwide cohort of patients with acromegaly, mainly related to circulatory and malignant diseases. Although still high, mortality significantly declined over time. This could be explained by the more frequent use of pituitary surgery, decreased prevalence of hypopituitarism and the availability of new medical treatment options.

AbstractIn recent decades, the biomedical literature has witnessed an increasing number of authors per article together with a concomitant increase of authors claiming to have contributed equally. In this study, we analyzed over 3000 publications from 1995–2017 claiming equal contributions for authors sharing the first author position for author number, gender, and gender position. The frequency of dual pairings contributing equally was male-male > mixed gender > female-female. For mixed gender pairs males were more often at the first position although the disparity has lessened in the past decade. Among author associations claiming equal contribution and containing three or more individuals, males predominated in both the first position and number of gender exclusive groupings. Our results show a disequilibrium in gender ratios among authors who contributed equally from expected ratios had the ordering been done randomly or alphabetical. Given the importance of the first author position in assigning credit for a publication, the finding of fewer than expected females in associations involving shared contributions raises concerns about women not receiving their fair share of expected credit. The results suggest a need for journals to request clarity on the method used to decide author order among individuals claiming to have made equal contributions to a scientific publication.
