Searching a biomedical bibliographic database from Bulgaria: the ABS database

BACKGROUND: The University of Sofia, Bulgaria, disseminates local biomedical literature (1994 to present) through a free online database, ABS. OBJECTIVES: Our objectives were to systematically search ABS, identify citations to controlled trials and discover what proportion of these studies are to be found on medline. METHODS: We searched using Bulgarian and English phrases; manually selected citations of controlled trials and sought these citations on medline. Results: Using the two languages, we found a total of 628 unique citations, 47 of which seem to be relevant controlled trials (precision 7.48%, 13% of ABS citations were found on medline). The trials in ABS commonly focused on evaluation of care for people with cardiovascular or urological problems. DISCUSSION: ABS is another source of easily accessed trials not readily available elsewhere.     

Landmark United States biomedical ethics cases: a selected bibliography

The past thirty years have demonstrated a dramatic shift in the traditional physician-patient relationship, from one that has traditionally been paternalistic, or physician-focused, to one that recognizes patient autonomy and is predominately patient-centered. This evolution of patient autonomy has revolutionized the field of medical-legal ethics, as evidenced by the numerous landmark court cases described in this paper. Patients have demanded, and received, the right to make their own decisions about a variety of issues, many of them end-of-life decisions, including withholding treatment, withdrawing treatment, refusing treatment, whether or not to be resuscitated, and their right to die with dignity. Technological advances in the areas of human experimentation, resuscitation, organ transplantation, and assisted reproduction have contributed to the ethical dilemmas faced by patients, physicians, ethicists, and the courts. Due in large part to this shift in attitude and behavior from paternalism to patient autonomy, and technological advances that allow people to live indefinitely, medical-ethical issues never before encountered are now in the forefront of many peoples' lives. The landmark United States ethical-legal cases cited here illustrate society's change in attitude which favors autonomous decision making by an increasingly consumer-oriented public.     

对医学期刊编辑的生物医学研究伦理审核意识的调研及建议

生物医学研究涉及很多医学研究伦理内容,编辑对论文中医学研究伦理的把关至关重要。本文通过问卷调研了228名医学期刊编辑的生物医学研究伦理审核意识,发现编辑对相关的医学研究伦理问题不是很了解,并且只有53.07%的编辑会经常要求作者提供相关医学研究伦理证明材料,大多数编辑所在期刊对论文中医学研究伦理内容只是进行了形式上的检查,没有要求作者提供如伦理审批件等的原始证明材料。据此提出,医学期刊编辑应了解科研人员在生物医学研究中应当遵循的科研伦理规范,掌握期刊编辑出版中关于生物医学研究伦理要求,提高审稿时对医学研究伦理内容的审核程度,进而加强医学期刊编辑对生物医学研究伦理审核意识的建设。

The national biomedical communications network as a developing structure

The National Biomedical Communications Network has evolved both from a set of conceptual recommendations over the last twelve years and an accumulation of needs manifesting themselves in the requests of members of the medical community. With a short history of three years this network and its developing structure have exhibited most of the stresses of technology interfacing with customer groups, and of a structure attempting to build itself upon many existing fragmentary unconnected segments of a potentially viable resourcesharing capability.In addition to addressing these topics, the paper treats a design appropriate to any network devoted to information transfer in a special interest user community. It discusses fundamentals of network design, highlighting that network structure most appropriate to a national information network. Examples are given of cost analyses of information services and certain conjectures are offered concerning the roles of national networks.     

国内外生物医学期刊稿件中医学伦理学意识比较

为了了解近年来我国与西方国家生物医学期刊在医学伦理学方面的意识是否有改善,选取2004和2005年出版的12种国外影响因子大于3的SCI收录期刊与11种中国科学引文数据库(CSCD)核心库收录期刊中刊登的论著进行比较.结果显示,国外医学期刊无论在获得伦理委员会批准还是受试者知情同意方面均好于国内医学期刊,而国内一些医学期刊几乎无医学伦理学意识.认为我国医学期刊应从提高编辑人员素质,重视医学伦理学的宣传教育,不同的稿件应区别对待,完善稿件中的知情同意以及其他医学伦理学问题等几个方面入手,积极改善缺乏医学伦理学意识的现状.

Battling the biomedical information explosion: a plan for implementing a quality filtered database.

In 1980 an article appeared in the Archives of Internal Medicine stating that two-thirds of the studies appearing in the best medical journals contain unwarranted conclusions. In order to deal with the ever increasing mass of biomedical information (termed a "journalistic blastoma" by one editor), IAIMS has extolled the use of quality filters, devices to sort through the literature and sift the good from the bad. The complexity of the task is staggering. Quality is obviously subjective, and its nature raises the question of whether our users can be taught the necessary skills to systematically evaluate the literature. This report is based on a research project that grew into an elective course for medical students at Texas Tech University School of Medicine on "Critical Appraisal of the Biomedical Literature."     

Area Health Education as the foundation for a statewide biomedical communications network

In 1972, the Medical University of South Carolina was awarded a contract to establish four Area Health Education Centers in South Carolina. These centers, based in community hospitals, provide residency programs and clinical instruction for medical, dental, nursing, pharmacy, and allied health students and continuing educational programs for health professionals. A plan for delivering library and other information services to the designated Area Health Education Centers is described.

Predicting the clinical citation count of biomedical papers using multilayer perceptron neural network

The number of clinical citations received from clinical guidelines or clinical trials has been considered as one of the most appropriate indicators for quantifying the clinical impact of biomedical papers. Therefore, the early prediction of clinical citation count of biomedical papers is critical to scientific activities in biomedicine, such as research evaluation, resource allocation, and clinical translation. In this study, we designed a four-layer multilayer perceptron neural network (MPNN) model to predict the clinical citation count of biomedical papers in the future by using 9,822,620 biomedical papers published from 1985 to 2005. We extracted ninety-one paper features from three dimensions as the input of the model, including twenty-one features in the paper dimension, thirty-five in the reference dimension, and thirty-five in the citing paper dimension. In each dimension, the features can be classified into three categories, i.e., the citation-related features, the clinical translation-related features, and the topic-related features. Besides, in the paper dimension, we also considered the features that have previously been demonstrated to be related to the citation counts of research papers. The results showed that the proposed MPNN model outperformed the other five baseline models, and the features in the reference dimension were the most important. In all the three dimensions, the citation-related and topic-related features were more important than the clinical translation-related features for the prediction. It also turned out that the features helpful in predicting the citation count of papers are not important for predicting the clinical citation count of biomedical papers. Furthermore, we explored the MPNN model based on different categories of biomedical papers. The results showed that the clinical translation-related features were more important for the prediction of clinical citation count of basic papers rather than those papers closer to clinical science. This study provided a novel dimension (i.e., the reference dimension) for the research community and could be applied to other related research tasks, such as the research assessment for translational programs. In addition, the findings in this study could be useful for biomedical authors (especially for those in basic science) to get more attention from clinical research.

The SUNY biomedical communication network: six years of progress in on-line bibiographic retrieval.

The SUNY Biomedical Communication Network became operational in 1968 as the first on-line bibliograhpic retrieval service for biomedical literature. Since 1968, the SUNY/BCN has grown in size from nine to thirty-two medical and university libraries and has expanded its data base coverage to include the ERIC and Psychological Abstracts data bases in addition to the full ten-year retrospective MEDLARS data base. Aside from the continuous provision of an on-line searching system, the SUNY experience over the last six years has yielded valuable information in the following areas of: (1) monograph indexing and retrieval, (2) shared cataloging, (3) user interaction and education in on-line systems, and (4) member participation in Network policy-making processes. The continued success of the SUNY/BCN is evidence that it is possible to provide a high quality on-line bibliographic retrieval system at cost to academic institutions. SUNY's success in this effort is the result of centralized resource sharing and effective regional networking, combined with thoughtful planning by user advisory committees.
