TRAVEL TO COUNTRY IATROGENIC. YATROGENIYA DIAGNOSTIC PROCEDURES (Message 3)
No full textA special group of iatrogenic complications are associated with various diagnostic manipulations — from a physical examination of the patient to angiographic studies, diagnostic laparoscopy or thoracoscopy. The article presents data on the frequency and nature of diagnostic iatrogenic in clinical practice. The range of diagnostic iatrogenesis in terms of its manifestations, severity and prognosis is wide enough — from skin irritation with gel during ultrasound to dissection of the coronary artery during coronary angiography. The article presents examples of iatrogenic diagnostic procedures, starting with the clinical examination process (collection of complaints and anamnesis, physical examination), and ending with complex invasive examinations. Yatrogenia, which occur with the use of preparations containing contrast (in particular iodine-containing drugs), which are widely used in clinical practice (CT with contrasting, angiography, etc.) with a diagnostic purpose, are considered in detail. The article describes the risk factors, knowledge of which and awareness of their presence in the patient are mandatory before the introduction of drugs containing contrast. The review of complications arising during endoscopic examinations was carried out. The author reminds that iatrogenic events in endoscopic procedures can be manifested not only by complications from the organ under examination (esophagus, stomach, intestines), but also depend on the patient’s condition, his preparation for the procedure, and the specialist’s possession of endoscopic technique. In conclusion, the author gives a clinical observation in which the risk factor of the iatrogenic event was the presence of an anomaly in the liver and pancreas duct systems in the patient. The author of the article encourages colleagues to pay more attention to the process of making a decision to conduct a diagnostic study, always to evaluate the benefit / risk ratio in terms of the real usefulness of the diagnostic study for the patient and the risk of complication development
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
TRAVEL TO COUNTRY IATROGENIC (Message 2)
Get PDFThe problem of iatrogenesis inevitably dictates the need for not only an exhaustive definition (which in principle is impossible), but also classification with a division into different species. The article deals with the main types of iatrogenia, the classification of iatrogenic proposed by I.A. Kassirsky, E.M. Tareev, S.Ya. Doletsky, A.V. Smolyannikov, V.V. Nekatchalov, and others, which are based on various principles and approaches. Given the expanded interpretation of iatrogenic and the need for a multidisciplinary approach to this problem among iatrogenic events, it is suggested to distinguish the following types of iatrogenic: psychogenic, hospital, therapeutic and preventive, iatrogenic diagnostic studies. Particular attention is paid in the article to psychogenic iatrogenia, which often arises in the process of communication between a doctor and patients. They consider not only iatrogenia, «having a starting point for the behavior of a doctor», but also iatrogenia, caused by certain traits of the patient’s character (insecurity, propensity to anxiety fears, increased attention to the slightest changes in health, emotional vulnerability, etc.), predetermining inadequate reactions to any Medical information. Of no small importance in the development of psychogenic iatrogenia is the quality of the medical documentation issued by the doctor to the patient (extracts from the case histories, advisory opinions, descriptions of research results, recommendations, etc.). In this case, it is necessary to avoid formulations that, without proper explanation, may be inadequately perceived by the patient and alert him or her. To the sources of psychogenic iatrogenic, some authors also refer to improperly conducted medical education, the publication of contentious, nonscientific results that do not meet the requirements of evidence-based medicine, although the doctor may not directly participate in this. The author of the article encourages colleagues to pay more attention to the process of communication with the patient, the preparation of documentation in the process of patient management, to remember that psychogenic iatrogenia can have negative consequences for the patient, and can be a source of violation of the relationship between the doctor and the patient
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
