    La asociaciĂłn buildingSMART tiene como principal objetivo fomentar la eficacia en el sector de la construcciĂłn a travĂ©s del uso de estĂĄndares abiertos de interoperabilidad con la metodologĂ­a BIM (Building InformationMode-ling). Para ello, cuenta con una estructura de grupos de trabajo a nivel internacional para abordar diferentes cues-tiones al respecto. Sin embargo, en el ĂĄmbito del Patrimonio Cultural, no existe en la actualidad una aproximaciĂłn internacional sobre el uso de BIM, y es por lo que buildingSMART Spanish Chapter ha puesto en marcha un grupo de trabajo abierto, denominado LEGEND–HBIM, y que estĂĄ centrado en BIM aplicado al Patrimonio Cultural. De este modo, buildingSMART Spanish Chapter continua la laborde promover el uso de la metodologĂ­a BIM a travĂ©s de guĂ­as como esta, que supone una continuaciĂłn de las guĂ­as uBIM publicadas en el año 2014

    The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

    The James Webb Space Telescope Mission

    Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least 4m4m. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the 6.5m6.5m James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

    Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

    Regulating Private Human Suborbital flight at the International and European Level: Tendencies and Suggestions

    No full text
    In the context of the FAST20XX project (Future High-Altitude High-Speed Transport) that started in 2009 under the 7th Framework Programme of the European Union (EU), the authors reexamined the legal status of private human suborbital flight, and researched whether it might be regulated as aviation or as spaceflight. International space law is ambiguous as to accommodating suborbital activities. While some provisions of the UN outer space treaties would seem to exclude them, generally there is not any explicit condition in terms of reaching orbit as a requirement for application. International air law presents equal difficulties in dealing with this activity. The classic definition of “aircraft” as contained in the Annexes to the Chicago Convention does not really encompass the kind of rocket-powered vehicles that are envisaged here. As a result, it is unclear whether the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), the International Civil Aviation Organization (ICAO), or both could be involved in an eventual international regulation of suborbital flight. In the absence of a uniform international regime, each state has the sovereign right to regulate human suborbital flights operating within its airspace. So far, two practical solutions have been realised or proposed, and will be analyzed. On the one hand, the USA granted power for regulation and licensing over private human suborbital flight to the Office of Commercial Space Transportation of the Federal Aviation Administration (FAA/AST). Subsequent regulations by the FAA have set out a series of requirements for companies that want to operate these flights, enabling a market to develop. On the other side of the Atlantic, both the European Space Agency (ESA) and a group of representatives of the European Aviation Safety Agency (EASA) of the European Union (EU) seem to rather regard this activity as aviation, potentially subject to the regulation and certification competences of EASA, although recent developments may indicate a changed view. Due to these differences, it is uncertain when this activity will be considered aviation and when it will be considered as spaceflight. However, the characterization as either of these has important consequences for the industry and for a stable regulatory landscape. In the longer term, from an international and a European perspective, the best solution for regulation may be to create a sui generis legal regime specifically addressing the particular nature of suborbital flight. Suborbital transportation is neither aviation nor spaceflight; it is rather something in between. A new legal regime would be able to combine notions of both air and space law, in order to overcome and resolve the current deficiencies of each discipline
