Echinoderm evolution since 1972 and since the cambrian: tales from a dozen IECS.
5 pages; International audience; Progress made since the first IEC - which took place in Washington, DC in 1972 has drastically altered some of our views on echinoderm evolution. In addition to publications in scientific journals, there are thousands of pages of peer-reviewed material in the proceedings of past IECs, and in Echinoderm Studies. These pages bear witness to some of the most outstanding milestones in this progress. This paper aims to highlight one third of a century of maturing ideas dealing with several key aspects of echinoderm evolution as witnessed by 12 IECs. Conceptual changes have taken place in a scientific milieu characterized by rapid adoption of new theoretical and p…
SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study
Abstract Background Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18–49, 50–69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results NNVs were more favourable in su…
