    Scientific ideas seldom come entirely from nothing; they often originate from existing knowledge. In this study, we aim to identify the relationship between the knowledge recency and Nobel Prize-winning articles (NPs) from the perspectives of gender, career stage, and country of the originators. Scientific literatures published by Nobel laureates in the Physiology or Medicine field are treated as NPs, and the age of references cited in those literatures are considered a measurement of knowledge recency. Results show that most NPs in this field have been focused on literature with a low mean and median recency, and over half of these works have cited equal to or more than 68 % of recent literature published within five years. Contrary to traditional wisdom, the greatest discoveries made after 1980 have shown an increasing favor to older literature. We also find that there has been no gender gap for the recency of NPs; however, career stage has been an important factor influencing knowledge recency, which means older researchers tend to cite more earlier articles than others. © 2020 Elsevier Ltd.

    Background: Gender disparity in authorship broadly persists in medical literature, little is known about female authorship within pulmonary medicine. Methods: A bibliometric analysis of publications from 2012 to 2021 in 12 journals with the highest impact in pulmonary medicine was conducted. Only original research and review articles were included. Names of the first and last authors were extracted and their genders were identified using the Gender-API web. Female authorship was described by overall distribution and distribution by country/region/continent and journal. We compared the article citations by gender combinations, evaluated the trend in female authorship, and forecasted when parity for first and last authorship would be reached. We also conducted a systematic review of female authorship in clinical medicine. Results: 14,875 articles were included, and the overall percentage of female first authors was higher than last authors (37.0% vs 22.2%, p<0.001). Asia had the lowest percentage of female first (27.6%) and last (15.2%) authors. The percentages of female first and last authors increased slightly over time, except for a rapid increase in the COVID-19 pandemic periods. Parity was predicted in 2046 for the first authors and 2059 for the last authors. Articles with male authors were cited more than articles with female authors. However, male-male collaborations significantly decreased, whereas female-female collaborations significantly increased. Conclusions: Despite the slow improvement in female authorship over the past decade, there is still a substantial gender disparity in female first and last authorship in high-impact medical journals in pulmonary medicine. © 2023 Sociedade Portuguesa de Pneumologia
