1Colorectal liver metastases: Current management and future perspectives显示文摘The liver is the commonest site of metastatic disease for patients with colorectal cancer,with at least 25%developing colorectal liver metastases(CRLM)during the course of their illness.The management of CRLM has evolved into a complex field requiring input from experienced members of a multi-disciplinary team involving radiology(cross sectional,nuclear medicine and interventional),Oncology,Liver surgery,Colorectal surgery,and Histopathology.Patient management is based on assessment of sophisticated clinical,radiological and biomarker information.Despite incomplete evidence in this very heterogeneous patient group,maximising resection of CRLM using all available techniques remains a key objective and provides the best chance of long-term survival and cure.To this end,liver resection is maximised by the use of downsizing chemotherapy,optimisation of liver remnant by portal vein embolization,associating liver partition and portal vein ligation for staged hepatectomy,and combining resection with ablation,in the context of improvements in the functional assessment of the future remnant liver.Liver resection may safely be carried out laparoscopically or open,and synchronously with,or before,colorectal surgery in selected patients.For unresectable patients,treatment options including systemic chemotherapy,targeted biological agents,intraarterial infusion or bead delivered chemotherapy,tumour ablation,stereotactic radiotherapy,and selective internal radiotherapy contribute to improve survival and may convert initially unresectable patients to operability.Currently evolving areas include biomarker characterisation of tumours,the development of novel systemic agents targeting specific oncogenic pathways,and the potential reemergence of radical surgical options such as liver transplantation.Jack Martin Angelica Petrillo Elizabeth C Smyth Nadeem Shaida Samir Khwaja HK Cheow Adam Duckworth Paula Heister Raaj Praseedom Asif Jah Anita Balakrishnan Simon Harper Siong Liau Vasilis Kosmoliaptsis Emmanuel Huguet 2020World Journal of Clinical Oncology2020,11,10:5
2Simulation in endoscopy:Practical educational strategies to improve learning显示文摘In gastrointestinal endoscopy, simulation-based training can help endoscopists acquire new skills and accelerate the learning curve. Simulation creates an ideal environment for trainees, where they can practice specific skills, perform cases at their own pace, and make mistakes with no risk to patients. Educators also benefit from the use of simulators, as they can structure training according to learner needs and focus solely on the trainee. Not all simulation-based training,however, is effective. To maximize benefits from this instructional modality,educators must be conscious of learners' needs, the potential benefits of training,and associated costs. Simulation should be integrated into training in a manner that is grounded in educational theory and empirical data. In this review, we focus on four best practices in simulation-based education: deliberate practice with mastery learning, feedback and debriefing, contextual learning, and innovative educational strategies. For each topic, we provide definitions,supporting evidence, and practical tips for implementation.Rishad Khan Michael A Scaffidi Samir C Grover Nikko Gimpaya Catharine M Walsh 2019World Journal of Gastrointestinal Endoscopy2019,11,3:3
3发展中国家的可再生能源:沼气的机遇和挑战显示文摘能源对于现代社会至关重要,是社会经济发展最重要的指标之一。尽管科技不断发展,但仍然有约30亿人(主要集中在发展中国家的农村地区),继续通过在传统的炉灶中燃烧生物质资源(如柴薪、秸秆、动物粪便)的方式来满足烹饪的能源需求。这种方式对环境、社会、经济、公众健康都带来极大负面影响。这些地区要实现可持续性发展,开发干净清洁、价格低廉的可再生能源就势在必行。把现有的生物质资源(动物粪便、秸秆、餐厨垃圾、绿色废弃物)提炼成更加清洁高效的能源载体(例如厌氧发酵产生的沼气),不仅具有提供清洁、可靠能源的独特潜力,同时又能保护当地和全球的环境。尽管沼气对发展中国家来说意义重大,但其面临着成本高、设备安装和维护专业知识缺乏等问题,因而在地理位置分散的社区难以广泛推广应用。因此,政府和非政府层面的通力协作就显得至关重要,从而促进沼气技术的更新改造和传播,开发尚未被开发的潜力。文章旨在通过分析沼气技术的现状、挑战和潜力,明确它在发展中国家未来的研究方向和发展传播路径。K C Surendra Devin Takara rew G Hashimoto Samir Kumar Khanal 李谦 2015中国沼气2015,33,1:3
