No full textHintergrund
Mit steigendem Alter wächst das Frakturrisiko, immer häufiger kommt es zu operationsbedürftigen Verletzungen von generell oft sehr multimorbiden Patienten. Die meisten dieser Frakturen sind osteoporose- assoziiert, wobei diese häufig nicht diagnostiziert und somit auch nicht behandelt wird. Zur Verbesserung der Versorgung dieser komplexen geriatrisch- traumatologischen Patienten wurde im Jahr 2014 das AltersTraumaRegister DGU® gegründet. Seit 2014 können sich Kliniken, in denen interdisziplinär unfallchirurgisch- geriatrische Patienten behandelt werden, als AltersTraumaZentrum DGU® zertifizieren. Für die Messung der Behandlungsqualität in den Zentren wurde das AltersTraumaRegister DGU aufgebaut.
Patienten und Methoden
Es wurden 118 Patienten mit proximaler Femurfraktur oder implantatassoziierter Fraktur sowie einem Alter von über 70 Jahren eingeschlossen. Erfasst wurden verschiedene Parameter bezüglich der Patientencharakteristika, der Behandlung sowie der Ergebnisse. Die Ermittlung der Lebensqualität erfolgte mittels EQ- 5D in der ersten postoperativen Woche.
Ergebnisse
Die operative Versorgung erfolgte bei 87% der Patienten innerhalb von 24Std. Die spezifische Osteoporosetherapie konnte im stationären Verlauf von 4 auf 63 Patienten gesteigert werden. Die gesundheitsbezogene Lebensqualität war in der ersten postoperativen noch stark erniedrigt.
Schlussfolgerung
Gemessen an den Behandlungsparametern „Operationszeitpunkt“ sowie „Einleitung einer Osteoporosetherapie“ scheint die Behandlung an den Zentren erfolgreich zu sein. Zur besseren Bewertung der Ergebnisqualität in den AltersTraumaZentren DGU® ist aber die Etablierung einer Nachuntersuchung im AltersTraumaRegister DGU essenziell, welche in bereits zertifizierten AltersTraumaZentren DGU routinemäßig nach 120 Tagen durchgeführt wird.8.1 Background
The risk of fractures increases in higher age, and also the number of injuries requiring surgery for patients who often are multimorbid. Most of these fractures are associated with osteoporosis, which is often not diagnosed and therefore not treated. To improve the care of these complex geriatric-traumatological patients, the AltersTraumaRegister DGU was founded in 2014. Since 2014, clinics in which trauma-surgical and geriatric patients are treated interdisciplinary have been able to certify themselves as AltersTraumaZentrum DGU. The AltersTraumaRegister DGU was set up to measure the quality of treatment in the centers.
Patients and Methods
118 patients with fracture of the proximal femur or implant-associated fracture and older than 70 years were included. Various parameters in terms of the patient characteristics, the treatment and results were recorded. The health- related quality of life was measured by EQ-5D in the first postoperative week.
Results
Surgery was performed in 87% of patients within 24h. Specific osteoporosis therapy could be increased from 4 to 63 patients. The health-related quality of life was still significantly reduced in the first postoperative period.
Conclusion
Measured by the treatment parameters “time of surgery” and “initiation of osteoporosis therapy”, the treatment at the centers seems to be successful. To improve the evaluation in term of the quality of the results in the AltersTraumaZentrum DGU, it is important to establish a follow-up examination, which is performed yet in certified AltersTraumaZentrum DGU
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
