Notwendigkeit und Umfang der postoperativen intensiv-medizinischen Überwachung von Patienten nach elektiven epilepsiechirurgischen Eingriffen
Full text linkHintergrund: Traditionell werden Patienten nach erfolgtem elektiven resektiven epilepsiechirurgischen Eingriff postoperativ auf einer (Neuro)-Intensivstation berwacht. Das Ziel der berwachung ist eine frhzeitige Erkennung von postoperativen lebensbedrohlichen Komplikationen oder klinischen Ereignissen, welche eine schnelle medizinische oder chirurgische Intervention bentigen. Wir haben in dieser Analyse die Hufigkeit des Auftretens von Ereignissen, welche eine intensiv-medizinische berwachung erforderten, sowie die dazu beitragenden mglichen pr- und intraoperativen Faktoren untersucht.
Methoden: wir haben eine retrospektive Studie mit n=266 Patienten mit medikamenten-resistenter Epilepsie, die sich zwischen 2012 und 2019 einem elektiven resektiven epilepsiechirurgischen Eingriff unterzogen, durchgefhrt. Postoperative Komplikationen oder klinischen Ereignissen, welche eine schnelle medizinische oder chirurgische Intervention bentigen, wurden innerhalb von 48 Stunden postoperativ erfasst. Eine multivariaten Analyse wurde zur Identifikation von unabhngigen signifikanten Einflussfaktoren durchgefhrt.
Ergebnisse: Dreizehn Patienten (4,9 %) entwickelten innerhalb von 48h postoperativ mindestens ein Ereignis, welches eine intensiv-medizinische berwachung erforderte. Die multivariaten Analyse zeigte, dass Diabetes Mellitus sowie ein intraop. Blutverlust = 325 mL unabhngige Prdiktoren fr die Notwendigkeit einer postoperativen intensiv-medizinischen berwachung sind.
Zusammenfassung: Zusammenfassend legen unsere Ergebnisse nahe, dass die Mehrheit der Patienten, die sich einem elektiven resektiven epilepsiechirurgischen Eingriff unterziehen, keine postoperativen Ereignisse entwickeln, welche mandatorisch ein intensivmedizinisches Setting erfordern. Somit erscheint die postoperative berwachung dieser Patienten auf einer IMC-berwachungsstation sicher und machbar. Allerdings sollten Patienten mit Diabetes mellitus und einem erhhten intraoperativen Blutverlust (>325 mL) weiterhin mit besonderer Umsicht behandelt werden und postoperativ einer intensivmedizinischen berwachung unterliegen.The necessity for routine intensive care unit admission following elective craniotomy for epilepsy surgery: a retrospective single-center observational study
OBJECTIVE Traditionally, patients who underwent elective craniotomy for epilepsy surgery are monitored postoperatively in an intensive care unit (ICU) overnight in order to sufficiently respond to potential early postoperative complications. In the present study, the authors investigated the frequency of early postoperative events that entailed ICU monitoring in patients who had undergone elective craniotomy for epilepsy surgery. In a second step, they aimed at identifying pre- and intraoperative risk factors for the development of unfavorable events to distinguish those patients with the need for postoperative ICU monitoring at the earliest possible stage.
METHODS The authors performed a retrospective observational cohort study assessing patients with medically intractable epilepsy (n = 266) who had undergone elective craniotomy for epilepsy surgery between 2012 and 2019 at a tertiary care epilepsy center, excluding those patients who had undergone invasive diagnostic approaches and functional hemispherectomy. Postoperative complications were defined as any unfavorable postoperative surgical and/or anesthesiological event that required further ICU therapy within 48 hours following surgery. A multivariate analysis was performed to reveal preoperatively identifiable risk factors for postoperative adverse events requiring an ICU setting.
RESULTS Thirteen (4.9%) of 266 patients developed early postoperative adverse events that required further postoperative ICU care. The most prevalent event was a return to the operating room because of relevant postoperative intracranial hematoma (5 of 266 patients). Multivariate analysis revealed intraoperative blood loss = 325 ml (OR 6.2, p = 0.012) and diabetes mellitus (OR 9.2, p = 0.029) as risk factors for unfavorable postoperative events requiring ICU therapy.
CONCLUSIONS The present study revealed routinely collectable risk factors that would allow the identification of patients with an elevated risk of postsurgical complications requiring a postoperative ICU stay following epilepsy surgery. These findings may offer guidance for a stepdown unit admission policy following epilepsy surgical interventions after an external validation of the results
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
