Mycotoxicosis – diagnosis,prevention and control: past practices and future perspectives

Abstract

Mycotoxins pose severe health hazards in animals, humans, and poultry birds. More than 400 chemically different mycotoxins have been identified to date. Twenty-five percent of world’s crops are potentially contaminated with mycotoxins. Luckily, nature has provided the ruminants a unique property of inactivating and detoxifying most of the mycotoxins with the help of microflora and microfauna present within their ruminal fluid; however, unfortunately avian species lack such ability putting them at high risk to the deleterious effects of mycotoxins. This review elaborates different strategies for diagnosis, prevention and control of mycotoxins.     

Surveillance systems for healthcare-associated infection in high and upper-middle income countries: A scoping review

BackgroundHealthcare-associated infection (HAI) surveillance is useful for improved infection control. To understand the current HAI surveillance systems (HAISS) trend globally, a scoping review was performed.Materials and methodsThe search strategy included academic literature review, Google search, and questionnaires by the Embassies of Japan (registration number: UMIN000036035). Eighty-two high and 56 upper-middle income countries defined by country income classification for the World Bank were targeted. The following information was reviewed: name of the system, official website, languages used in the official website, foundation year, operating body, survey type (prevalence or incidence), reporting periodicity, mode of participation (mandatory or voluntary), targeted medical facilities, targeted HAIs and definitions, targeted antimicrobial resistant pathogens, and parameters. Online accessibility of the official websites of the SS was assessed through Google search.Results and conclusionForty-two (30.4%) countries (35 [42.7%] high and 7 [12.5%] upper-middle income countries) had national HAISS. Most systems operated on a voluntary basis, monitored HAI incidence, and used the Center for Disease Control and Prevention definitions. Methicillin-resistant Staphylococcus aureus, surgical site infection, and catheter-related blood stream infection were most commonly monitored. Surveillance for device-associated infections was implemented mainly in intensive care units. Thirty-five countries had at least one official website on their systems, while 7 (20.0%) were identified in the top 30 Google search hits, in English. Approximately half of the academic articles identified through PubMed were from three English-speaking countries. The feasibility and benefits of standardization of the HAI surveillance criteria and efficient feedback methods are future considerations.     

日本汉方药企业近十年申请专利的分析及思考——以津村制药和Kracie为例＊

目的 对日本医疗用汉方医药品和一般用汉方医药品市场占有率最大的企业日本津村制药公司和Kracie制药公司2008-2020年间申请的专利内容进行综述，为国内中药经典名方和保健食品研发、知识产权保护提供参考。方法 通过日本专利局的官方检索渠道J-PlatPat平台，检索日本津村制药公司和Kracie制药公司在2008年至2020年间申请的专利，并进行专利布局和技术内容分析。结果 共收集43项日本津村制药公司特许和实用新案专利，其围绕汉方制剂产品全过程质量控制构建了坚实的专利技术体系；共收集52项Kracie制药公司特许和实用新案专利，其致力于功能性制剂和组合物的开发，重点在生活改善、老龄化和癌症等领域进行专利布局，还创建了多种产品功效和功能的客观评价方法。结论 津村制药近十年专利布局提示在中药现代化制造和走向国际的过程中，应把提高品质作为主攻方向，树立持续质量改进理念，完善产品有效性证据链。Kracie制药公司践行的以人为中心的汉方药设计理念，以及精准满足消费者健康需求的研发模式值得借鉴。     

新型冠状病毒肺炎疫情下生理学线上教学的探索与反思

面对新型冠状病毒肺炎疫情向课堂教学提出的挑战，齐齐哈尔医学院生理学教学团队构建了基于"小规模限制性在线课程（small private online course，SPOC）+同步直播"的混合式教学，开展线上教学。经过团队成员的共同努力，开展线上教学4周以来教学秩序稳定，教学效果良好。本文以236名2019级护理本科生生理学教学为例，介绍了疫情形势下线上教学的教学设计、实施措施、教学效果以及教学反思，为进一步推进疫情防控期间医学高等院校线上教学工作提供实践经验。     

伴述情障碍的精神分裂症患者的抑制控制

目的:研究伴述情障碍的精神分裂症患者的抑制控制功能。方法:对50例符合入组标准的伴述情障碍的精神分裂症患者以及年龄、性别、受教育程度相匹配的50名精神分裂症患者实施Stroop色词测验。结果:与对照组相比,伴述情障碍的精神分裂症患者Stroop色词测验卡片C反应时长于对照组(t=3.104,P0.01)、正确阅读数低于对照组(t=-2.882,P0.01);卡片A反应时、正确阅读数差异均无统计学意义(t=1.285,-0.995;P0.05),卡片B反应时与对照组差异无统计学意义(t=1.81,P0.05),正确阅读数差异无统计学意义(t=-1.247,P0.05)。与对照组相比,伴述情障碍的精神分裂症患者干扰量高于对照组(t=2.264,P0.05)。结论:伴述情障碍的精神分裂症患者相对非述情障碍的精神分裂症患者存在更严重的抑制控制功能损害,临床工作中应给予针对性的认知干预,将有助于促进康复。     

CYTED Network to develop an immunogen compatible with integrated management strategies for tick control in cattle

INCOGARR is a thematic network recently approved to be financially supported by the Ibero-American Program of Science and Technology for Development (CYTED). The objectives of this Network are the design and evaluation of an efficient and feasible anti-tick vaccine candidate from the technical and economical points of view and also sharing experiences in the immunological control of ticks as part of an Integrated Control Program. The Network consists of seven laboratories and one company from six countries. The first meeting of the Network took place with the representation of each laboratory involved. In the meeting, general and specific objectives and activities of the Network were discussed and it was a very nice example of international collaboration to address an unsolved worldwide topic on tick control in which laboratories with different competencies and expertise join their efforts in a common goal.
