Practice and future development of the medical research summer school / 中华医学科研管理杂志

Objective Peking University Health Science Center,together with Keio University,King's College London and Karolinska Institutet developed a cooperative medical research summer school.It integrates the education methods of lectures,lab rotations and visits etc.,which forms a special model.This study aims to analyze and evaluate the effect,prospect and space for further improvement of the summer school.Methods Program documents review and evaluation,interview and questionnaire survey to teachers as well as students who engaged in such program.Results The sum mer school enhances the research cooperation and communication among faculties and students from participating universities;it is highly appraised by participating teachers and students;students are particularly satisfied in the following aspects:gain knowledge and skills in cross-cultural communication,develop global health knowledge,gain knowledge and skills in research,and also enhance the sense of commitment in research.Conclusions The research summer school can improve the postgrad uate education standard,promote scientific cooperation,and improve students' research capacity.However,there are still some space for further improvement,such as improve the recruitment process;enhance the platform support;strengthen the evaluation,feedback and follow up system;further develop the program in depth and breadth.

Papel de la colaboración científica en el impacto de la investigación en salud de Cuba en el contexto de América Latina / The role of scientific collaboration in the impact of Cuban health research on the Latin American context / Papel da colaboração científica no impacto da investigaçãon em saúde de Cuba no contexto de América Latina

Con el objetivo de descubrir los patrones de colaboración científica y su impacto en los índices de citación de la investigación en salud de Cuba según áreas del conocimiento, en el período 2009-2013, se exploró Scival, la plataforma para estudios cienciométricos desarrollada por Elsevier, a partir de los datos suministrados por Scopus correspondientes a los países e indicadores seleccionados. En comparación con los países de América Latina estudiados, predominaron los bajos niveles de cooperación internacional en las áreas que constituyen el pilar del Sistema Nacional de la Salud de Cuba, la atención primaria: Medicina, Estomatología y Enfermería, así como altos porcentajes de artículos escritos con colaboración institucional, comportamientos que tienden a reducir los niveles de citación de las contribuciones nacionales en el contexto internacional. Los niveles de citación de los artículos escritos por autores cubanos con cooperación internacional en el total de las áreas del conocimiento analizadas, salvo en el caso de las neurociencias, es superior al de los elaborados con cooperación nacional e institucional y sin colaboración. La colaboración científica es una vía apropiada tanto para obtener mayores y mejores resultados en la investigación en salud como para aumentar sus niveles de citación.

In order to discover the patterns of scientific collaboration and its impact on citation rates for Cuban health research by areas of knowledge from 2009 to 2013, Scival, as a platform for scientometrical studies developed by Elsevier from Scopus data, was explored regarding the chosen countries and indicators. Compared with the Latin American countries studied, low levels of international collaboration predominated in the areas that constitute the pillar of Cuban National Health System: primary care (medicine, dentistry and nursing). Also, high percentages predominated regarding articles written with institutional collaboration, a behavior that tends to reduce levels of citation of national contributions in the international context. The citation levels of articles written by Cuban authors with international cooperation in the whole number of the analyzed areas of knowledge, except for the case of neurosciences, are higher than the levels of the ones elaborated with national and institutional cooperation or without any collaboration. Scientific collaboration is an appropriate way both to obtain more and better results in health research and to increase their levels of citation.

Em comparação com os países da América Latina estudados, predominaram os baixos níveis de cooperação internacional nas áreas que constituem o alicerce do Sistema Nacional da Saúde de Cuba, a atenção primária: Medicina, Estomatologia e Enfermagem; assim como altas percentagens de artigos escritos com colaboração institucional, comportamentos que tendem a reduzir os níveis de citação das contribuições nacionais no contexto internacional. Os níveis de citação dos artigos escritos por autores cubanos com cooperação internacional no total das áreas do conhecimento analisadas, salvo as Neurociências, são superiores ao dos elaborados com cooperação nacional e institucional e sem colaboração.

HUMAN T-LYMPHOTROPIC VIRUS 1 (HTLV-1) AND HUMAN T-LYMPHOTROPIC VIRUS 2 (HTLV-2): GEOGRAPHICAL RESEARCH TRENDS AND COLLABORATION NETWORKS (1989-2012)

Publications are often used as a measure of research work success. Human T-lymphotropic virus (HTLV) type 1 and 2 are human retroviruses, which were discovered in the early 1980s, and it is estimated that 15-20 million people are infected worldwide. This article describes a bibliometric review and a coauthorship network analysis of literature on HTLV indexed in PubMed in a 24-year period. A total of 7,564 documents were retrieved, showing a decrease in the number of documents from 1996 to 2007. HTLV manuscripts were published in 1,074 journals. Japan and USA were the countries with the highest contribution in this field (61%) followed by France (8%). Production ranking changed when the number of publications was normalized by population (Dominican Republic and Japan), by gross domestic product (Guinea-Bissau and Gambia), and by gross national income per capita (Brazil and Japan). The present study has shed light on some of the defining features of scientific collaboration performed by HTLV research community, such as the existence of core researchers responsible for articulating the development of research in the area, facilitating wider collaborative relationships and the integration of new authors in the research groups.

Graphic database Neo4 J-based research and practice of co-authorship network / 中华医学图书情报杂志

Research of co-authorship network can reveal the scientific research collaboration network and can thus help us to have an understanding of it. Graphic database and Neo4J were described in detail due to the limitations of relationship database in processing the data of co-authorship network. Graphic database Neo4J-based research and practice of co-authorship network were analyzed with the Institutional Knowledge System of AMMS that we were involved in its construction as an example, and the advantages of Neo4J-based co-authorship network were summarized.

A Planned Prospective, Randomized, Placebo-Controlled Multicenter Trial Assessing the Effect of Helicobacter pylori Eradication on the Healing of Iatrogenic Ulcer after Endoscopic Resection of Gastric Neoplasm

BACKGROUND/AIMS: Helicobacter pylori eradication may facilitate the healing of iatrogenic ulcer after endoscopic resection of gastric neoplasm. This study involved designing a randomized, double-blinded, placebo-controlled, multicenter trial, performed by the Korean College of Helicobacter and Upper Gastrointestinal Research and the Medical Research Collaboration Center, Seoul National University Hospital. METHODS: We intend to enroll up to 232 patients H.-pylori-positive patients who have gastric adenoma or early gastric cancer after endoscopic resection. The enrolled patients are being randomly allocated to the H.-pylori-eradication-plus-proton-pump-inhibitor group or the placebo-plus-proton-pump-inhibitor group based on their histology results and the size of the resected specimen. After random allocation, the iatrogenic ulcer size and stage are evaluated at 4- and 8-week follow-ups (with a window of +/-7 days). The primary end point is the healing rate of the ulcer by stage, and the secondary end point is the rate of ulcer size reduction, relief rate from ulcer-related symptoms, and adverse-event rates. RESULTS: More than 90% of the target subjects have already been enrolled into the study and are receiving ongoing periodic monitoring by the Medical Research Collaboration Center. CONCLUSIONS: Completion of the study should reveal whether H. pylori eradication can facilitate the healing of ulcer after endoscopic resection in Korea.
