    Open Science principles for accelerating trait-based science across the Tree of Life

    Synthesizing trait observations and knowledge across the Tree of Life remains a grand challenge for biodiversity science. Species traits are widely used in ecological and evolutionary science, and new data and methods have proliferated rapidly. Yet accessing and integrating disparate data sources remains a considerable challenge, slowing progress toward a global synthesis to integrate trait data across organisms. Trait science needs a vision for achieving global integration across all organisms. Here, we outline how the adoption of key Open Science principles-open data, open source and open methods-is transforming trait science, increasing transparency, democratizing access and accelerating global synthesis. To enhance widespread adoption of these principles, we introduce the Open Traits Network (OTN), a global, decentralized community welcoming all researchers and institutions pursuing the collaborative goal of standardizing and integrating trait data across organisms. We demonstrate how adherence to Open Science principles is key to the OTN community and outline five activities that can accelerate the synthesis of trait data across the Tree of Life, thereby facilitating rapid advances to address scientific inquiries and environmental issues. Lessons learned along the path to a global synthesis of trait data will provide a framework for addressing similarly complex data science and informatics challenges

    Trends and outcome of neoadjuvant treatment for rectal cancer: A retrospective analysis and critical assessment of a 10-year prospective national registry on behalf of the Spanish Rectal Cancer Project

    Introduction: Preoperative treatment and adequate surgery increase local control in rectal cancer. However, modalities and indications for neoadjuvant treatment may be controversial. Aim of this study was to assess the trends of preoperative treatment and outcomes in patients with rectal cancer included in the Rectal Cancer Registry of the Spanish Associations of Surgeons. Method: This is a STROBE-compliant retrospective analysis of a prospective database. All patients operated on with curative intention included in the Rectal Cancer Registry were included. Analyses were performed to compare the use of neoadjuvant/adjuvant treatment in three timeframes: I)2006–2009; II)2010–2013; III)2014–2017. Survival analyses were run for 3-year survival in timeframes I-II. Results: Out of 14, 391 patients, 8871 (61.6%) received neoadjuvant treatment. Long-course chemo/radiotherapy was the most used approach (79.9%), followed by short-course radiotherapy ± chemotherapy (7.6%). The use of neoadjuvant treatment for cancer of the upper third (15-11 cm) increased over time (31.5%vs 34.5%vs 38.6%, p = 0.0018). The complete regression rate slightly increased over time (15.6% vs 16% vs 18.5%; p = 0.0093); the proportion of patients with involved circumferential resection margins (CRM) went down from 8.2% to 7.3%and 5.5% (p = 0.0004). Neoadjuvant treatment significantly decreased positive CRM in lower third tumors (OR 0.71, 0.59–0.87, Cochrane-Mantel-Haenszel P = 0.0008). Most ypN0 patients also received adjuvant therapy. In MR-defined stage III patients, preoperative treatment was associated with significantly longer local-recurrence-free survival (p < 0.0001), and cancer-specific survival (p < 0.0001). The survival benefit was smaller in upper third cancers. Conclusion: There was an increasing trend and a potential overuse of neoadjuvant treatment in cancer of the upper rectum. Most ypN0 patients received postoperative treatment. Involvement of CRM in lower third tumors was reduced after neoadjuvant treatment. Stage III and MRcN + benefited the most

    Plant diversity dynamics over space and time in a warming Arctic

    The Arctic is warming four times faster than the global average 1 and plant communities are responding through shifts in species abundance, composition and distribution 2–4 . However, the direction and magnitude of local changes in plant diversity in the Arctic have not been quantified. Using a compilation of 42,234 records of 490 vascular plant species from 2,174 plots across the Arctic, here we quantified temporal changes in species richness and composition through repeat surveys between 1981 and 2022. We also identified the geographical, climatic and biotic drivers behind these changes. We found greater species richness at lower latitudes and warmer sites, but no indication that, on average, species richness had changed directionally over time. However, species turnover was widespread, with 59% of plots gaining and/or losing species. Proportions of species gains and losses were greater where temperatures had increased the most. Shrub expansion, particularly of erect shrubs, was associated with greater species losses and decreasing species richness. Despite changes in plant composition, Arctic plant communities did not become more similar to each other, suggesting no biotic homogenization so far. Overall, Arctic plant communities changed in richness and composition in different directions, with temperature and plant–plant interactions emerging as the main drivers of change. Our findings demonstrate how climate and biotic drivers can act in concert to alter plant composition, which could precede future biodiversity changes that are likely to affect ecosystem function, wildlife habitats and the livelihoods of Arctic peoples 5,6

    La transfusión es una necesidad permanente, y la amplitud con la que es utilizada exige que deba garantizarse su calidad y seguridad para evitar, en particular, la transmisión de enfermedades. Ha de ser un tratamiento personalizado. Las funciones de enfermería son de especial importancia así como los cuidados que se requieren. El objetivo del presente estudio es conocer la variabilidad práctica de los profesionales de enfermería del centro hospitalario, sobre la extracción de muestras pretransfusionales y la administración de hemoderivados. Para lo cual se realizó el envío de un cuestionario para su posterior cumplimentación en formato online, que garantizaba el total anonimato. Han contestado a la encuesta 180 profesionales. El 74.4% de los enfermeros dice que la transfusión de hemoderivados sólo se puede administrar de forma simultánea con suero fisiológico. Un 56.1% refiere que cada concentrado transfundido de hematíes aumenta la hemoglobina en 1gr/dl. Hemos encontrado un consenso entre las recomendaciones científicas y las contestaciones realizadas por los diferentes profesionales, hecho que se reafirma con el escaso índice de notificaciones adversas que se han registrado en nuestro trabajo. La elaboración e implantación de una guía de actuación en cuanto a la administración de hemoderivados se hace imprescindibleABSTRACT Transfusion is an ongoing need, and as widely used it requires that quality and safety should be ensured to avoid, in particular, the transmission of diseases. It must be a custom treatment. Nursing roles are particularly important as the care required. The aim of this study is to determine the variability of nursing skills on the extraction of pre-transfusion samples and administration of blood products. Anonymous questionnaires were sent out on-line for subsequent filling and 180 nursing professionals participated. 74.4% of nurses said that blood transfusion can only be administered simultaneously with normal saline, 56.1% reported that each transfused packed red blood cells increases hemoglobin 1 g / dl. We found a consensus among the scientific recommendations and the responses made by different professionals, a fact that is confirmed by the low rate of adverse notifications registered in our study. The development and implementation of policy guidance regarding the administration of blood products is essential
