    Crop genetic resources carry variation useful for overcoming the challenges of modern agriculture. Molecular markers can facilitate the selection of agronomically important traits. The pervasiveness of genomics research has led to an overwhelming number of publications and databases, which are, nevertheless, scattered and hence often difficult for plant breeders to access, particularly those in developing countries. This situation separates them from developed countries, which have better endowed programs for developing varieties. To close this growing knowledge gap, we conducted an intensive literature review and consulted with more than 150 crop experts on the use of molecular markers in the breeding program of 19 food security crops. The result was a list of effectively used and highly reproducible sequence tagged site (STS), simple sequence repeat (SSR), single nucleotide polymorphism (SNP), and sequence characterized amplified region (SCAR) markers. However, only 12 food crops had molecular markers suitable for improvement. That is, marker-assisted selection is not yet used for Musa spp., coconut, lentils, millets, pigeonpea, sweet potato, and yam. For the other 12 crops, 214 molecular markers were found to be effectively used in association with 74 different traits. Results were compiled as the GCP Molecular Marker Toolkit, a free online tool that aims to promote the adoption of molecular approaches in breeding activities

    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

    CapĂ­tulo 2 del libro digital: Clima, agua y producciĂłn sostenible: Aportes desde la acciĂłn acadĂ©mica CEMEDE - HIDROCECEn esta investigaciĂłn se caracterizaron los sistemas de captaciĂłn de agua en los cantones de Hojancha y Nicoya, en Guanacaste, Costa Rica. EspecĂ­ficamente, se documentaron las razones que incentivaron a los agricultores a construir estos sistemas. Adicionalmente, se analizĂł la percepciĂłn de los agricultores acerca del estado actual del funcionamiento de estos sistemas, asĂ­ como, de los beneficios obtenidos durante los meses de aridez estacional. La informaciĂłn fue obtenida por medio de visitas a las fincas, registrando la ubicaciĂłn espacial de los sistemas, tomando fotografĂ­as del estado actual de la infraestructura de los sistemas. AdemĂĄs, se utilizaron encuestas que fueron aplicadas en finca, a los once dueños de sistemas de captaciĂłn de agua. El diseño colaborativo de la metodologĂ­a, asĂ­ como el trabajo de campo, la transcripciĂłn de las encuestas y el anĂĄlisis de la informaciĂłn fue realizada por los estudiantes y acadĂ©micos de la Universidad Nacional (UNA). Los productores encuestados establecieron que el principal beneficio de los sistemas de captaciĂłn es que pueden proporcionar el agua necesaria para desarrollar actividades agropecuarias durante la aridez estacional (seis meses). Esta es la temporada mĂĄs difĂ­cil para el desarrollo de la ganaderĂ­a y la agricultura en estos cantones. Los sistemas de captaciĂłn de agua les permiten adaptarse a los problemas de escasez hĂ­drica que se han agravado en los Ășltimos diez años. A partir del anĂĄlisis de los resultados, se identificaron oportunidades para mejorar el diseño tĂ©cnico de los sistemas, asĂ­ como, la necesidad de continuar investigando, a fin de, evaluar la eficiencia de la tecnologĂ­a y las implicaciones de implementar los sistemas de captaciĂłn de agua, para solventar la disponibilidad hĂ­drica en la regiĂłn.Centro Mesoamericano de Desarrollo Sostenible del TrĂłpico Seco (CEMEDE-UNA)Universidad Nacional, Costa RicaUniversidad Nacional, Sede Regional Chorotega, Costa RicaCentro Mesoamericano de Desarrollo Sostenible del TrĂłpico Seco (CEMEDE-UNA

    Global attitudes in the management of acute appendicitis during COVID-19 pandemic: ACIE Appy Study

    No full text
    Background: Surgical strategies are being adapted to face the COVID-19 pandemic. Recommendations on the management of acute appendicitis have been based on expert opinion, but very little evidence is available. This study addressed that dearth with a snapshot of worldwide approaches to appendicitis. Methods: The Association of Italian Surgeons in Europe designed an online survey to assess the current attitude of surgeons globally regarding the management of patients with acute appendicitis during the pandemic. Questions were divided into baseline information, hospital organization and screening, personal protective equipment, management and surgical approach, and patient presentation before versus during the pandemic. Results: Of 744 answers, 709 (from 66 countries) were complete and were included in the analysis. Most hospitals were treating both patients with and those without COVID. There was variation in screening indications and modality used, with chest X-ray plus molecular testing (PCR) being the commonest (19\ub78 per cent). Conservative management of complicated and uncomplicated appendicitis was used by 6\ub76 and 2\ub74 per cent respectively before, but 23\ub77 and 5\ub73 per cent, during the pandemic (both P < 0\ub7001). One-third changed their approach from laparoscopic to open surgery owing to the popular (but evidence-lacking) advice from expert groups during the initial phase of the pandemic. No agreement on how to filter surgical smoke plume during laparoscopy was identified. There was an overall reduction in the number of patients admitted with appendicitis and one-third felt that patients who did present had more severe appendicitis than they usually observe. Conclusion: Conservative management of mild appendicitis has been possible during the pandemic. The fact that some surgeons switched to open appendicectomy may reflect the poor guidelines that emanated in the early phase of SARS-CoV-2

    Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P &lt; 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
