    In der Dachauer Reanimationsstudie konnten in einem Zeitraum von 5 Jahren Ergebnisse von 539 Reanimations-Patienten erhoben werden, davon 405 kardialer Genese. Von diesen Patienten überlebten 11,6% bis zur Klinikentlassung. Im internationalen Vergleich lagen die Überlebensraten im Landkreis Dachau im oberen Niveau. Dennoch ist dieser Anteil deutlich niedriger, als die theoretisch denkbaren Überlebensraten nach Reanimation. Entscheidend ist jedoch das neurologische Ergebnis: 91% unserer Patienten wiesen ein gutes neurologisches Outcome auf. Nach wie vor schwierig ist die Versorgung traumatologischer Reanimationen, die trotz maximaler Therapie eine infauste Prognose aufwiesen.The prehospital resuscitation study in Dachau included the outcome of 539 Patients with out-of-hospital cardiac arrest, of those 405 with cardiac cause. Of these 11.6% survived till release from hospital. Compared to international studies the survival rate in the area of Dachau was in the upper level. Even though this rate is quite lower than the thinkable survival rate after out-of-hospital cardiac arrest. But most deciding is the neurological outcome: 91% of our patients had a favorable neurological outcome. Still difficult is the treatment of trauma patients with cardiac arrest, which in spite of getting maximum therapy still have a very bad prognoses

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    Acute and Long-Term Results of Slow Pathway Ablation in Patients with Atroventricular Nodal Reentrant Tachycardia. An Analysis of the Predictive Factors for Arrhythmia Recurrence.

    Die AV-Knoten-Reentry-Tachykardie (AVNRT) ist eine der häufigsten regelmäßigen supraventrikulären Tachykardien. Zugrunde liegend ist hierbei eine funktionelle Aufteilung des AV-Knotens in zwei longitudinale Leitungsbahnen, einen langsam leitenden "slow pathway" und einen schnell leitenden "fast pathway", die bei laufender Tachykardie einen Reentrykreislauf bilden. Die einzig kausale Therapie einer AVNRT ist die Katheterablation einer der beiden Leitungsbahnen, bevorzugt des "slow pathway". Diese Studie hatte zum Ziel sowohl die kurz-als auch die langfristigen Ergebnisse bei 506 Patienten (mittleres Alter 52,6 ± 16 Jahre, 315 Frauen) nach Ablation des langsamen Leitungswegs auszuwerten und Paramter zu bestimmen, anhand derer die Wahrscheinlichkeit für ein Rezidiv der AVNRT nach primär erfolgreicher Ablation bestimmt werden kann. Besonderes Augenmerk wurde dabei auf die residualen Leitungseigenschaften des slow pathway am Ende der Ablation gelegt. Diese Studie zeigt, dass allein das Alter des Patienten als Vorhersagewert für das Auftreten eines Rezidivs herangezogen werden kann - je jünger der Patient, desto häufiger tritt ein Rezidiv auf. Alle anderen klinischen und elektrophysiologischen Parameter erwiesen sich als nicht signifikant für die Wahrscheinlichkeit eines Rezidivs.The AV-Nodal Reentrant Tachykardia (AVNRT) is one of the most common regular supraventricular tachycardias. The underlying basis shall be the functional segmentation of the AV node in two longitudinal pathways, a slowly transmitting "slow pathway" and a rapidly transmitting "fast pathway", which form a reentry circulation during an ongoing tachycardia. The only casual therapy of an AVNRT is the catheter ablation of one of the pathways, preferably the slow pathway. The objective of this study was both the evaluation of the acute and long-term results of 506 patients (mean age 52,6 ± 16 years, 315 women) after ablation of the slow pathway and the determination of parameters which serve as the basis for determing the probability of a recurrence of the tachycardia after a primary successful ablation. In this process, particular attention was paid to the residual conduction of the slow pathway after ablation. This study shows that solely the age of a patient ca be used as a predictive value for the occurence of a recurrence - the younger the patient, the more frequently the occurence of a recurrence. All remaining clinical and electrophysiological parameters prove to be non-significant for the probability of a recurrence

    Dispelling the Myths Behind First-author Citation Counts

    We 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

    We 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
