Current trends in the treatment of rhegmatogenous retinal detachment and perioperative positioning strategies in Germany: results of a retina.net survey
No full textZusammenfassung Hintergrund Die rhegmatogene Netzhautablösung (Amotio retinae) ist ein ophthalmologischer Notfall mit steigender Inzidenz in Deutschland. Trotz etablierter Methoden bleibt die perioperative Lagerung, insbesondere bei immobilen Patienten, eine Herausforderung, die Erfolg und Komplikationsrate maßgeblich beeinflusst. Eine Analyse der aktuellen Trends in der chirurgischen Behandlung und perioperativen Versorgung der Amotio im Vergleich zu 2018 ist essenziell. Material und Methoden Online-Umfrage mit 5 hypothetischen Fällen akuter rhegmatogener Amotio wurde an vitreoretinale Chirurg*innen des retina.net gesendet; 27 Fragebögen wurden hinsichtlich demografischer Daten, Operationsmethoden, Anästhesieform, perioperativer Lagerung und Nachsorgestrategien ausgewertet. Ergebnisse Es waren 50 % der Befragten über 50 Jahre alt, 86 % tätig an Universitätsaugenkliniken, und 89 % hatten über 1000 vitreoretinale Operationen durchgeführt. Prä- und postoperativ wird bei einer Amotio des temporal oberen Quadranten Temporalseitenlagerung empfohlen; 86 % sehen die postoperative Lagerung zur Vermeidung von Makulafalten als entscheidend an. Eine vollständige Drainage subretinaler Flüssigkeit streben 82 % an. Die häufigste Trokargröße war 23 G (77 %). Bei phaken Augen mit einfacher Lochsituation würden 86 % Buckelchirurgie anwenden; 50 % der Operateure nutzen bei komplexen inferioren Amotiones Silikonöl. Vollnarkose war die bevorzugte Anästhesieform (61 %), stets unter stationären Bedingungen. Zusammenfassung Bei Amotiones des temporal oberen Quadranten wird prä- und postoperativ bevorzugt die Temporalseiten-, gefolgt von der Bauchlagerung angeordnet. Für inferiore Amotiones wird bei Silikonöl- oder Buckelchirurgie meist keine spezielle Lagerung empfohlen; 86 % sehen die postoperative Lagerung nach Pars-plana-Vitrektomie (ppV) und Gasendotamponade als entscheidend zur Vermeidung von Makulafalten. Das 23-G-Trokarsystem bleibt die erste Wahl trotz kleinerer Alternativen. In bestimmten Fällen behält die Buckelchirurgie ihren Stellenwert.Abstract Background Rhegmatogenous retinal detachment (RRD) is an ophthalmological emergency with an increasing incidence in Germany. Despite established methods, perioperative positioning is important to improve outcomes and avoid complications but may be challenging, particularly in immobile patients. An analysis of the current trends in surgical treatment and perioperative positioning practices for RRD in Germany compared to historical data from 2018 is essential. Material and methods An online survey with five hypothetical cases of acute RRD was distributed to vitreoretinal surgeons via the retina.net research network. A total of 27 questionnaires were analyzed focusing on participant demographic data, surgical techniques, anesthesia types, perioperative positioning and aftercare strategies. Results Of the respondents 50% were over 50 years old, 86% worked at university eye clinics and 89% had performed over 1000 vitreoretinal procedures. For RRD in the temporal upper quadrant, preoperative and postoperative temporal lateral positioning is recommended. Of the respondents 86% consider postoperative positioning crucial to prevent macular folds. Complete subretinal fluid drainage is favored by 82% and 23 G trocars were used by 77%. For phakic eyes with uncomplicated RRD 86% chose buckling surgery, while 50% opted for silicone oil in complex inferior RRD cases. General anesthesia was preferred by 61%, always in an in-patient setting. Conclusion Preoperative and postoperative temporal lateral positioning followed by prone positioning is favored for temporal upper quadrant RRD, whereas no specific positioning is recommended for inferior RRD managed with silicone oil or buckling surgery. Postoperative positioning after pars plana vitrectomy (ppV) and gas endotamponade is considered by 86% to be decisive in preventing macular folds. The 23 G trocar system remains the preferred choice despite smaller alternatives. In certain cases buckling is still of importance.Zusammenfassung Hintergrund Die rhegmatogene Netzhautablösung (Amotio retinae) ist ein ophthalmologischer Notfall mit steigender Inzidenz in Deutschland.

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
Evaluation of the accuracy and readability of ChatGPT-4 and Google Gemini in providing information on retinal detachment: a multicenter expert comparative study
No full textAbstract Background Large language models (LLMs) such as ChatGPT-4 and Google Gemini show potential for patient health education, but concerns about their accuracy require careful evaluation. This study evaluates the readability and accuracy of ChatGPT-4 and Google Gemini in answering questions about retinal detachment. Methods Comparative study analyzing responses from ChatGPT-4 and Google Gemini to 13 retinal detachment questions, categorized by difficulty levels (D1, D2, D3). Masked responses were reviewed by ten vitreoretinal specialists and rated on correctness, errors, thematic accuracy, coherence, and overall quality grading. Analysis included Flesch Readability Ease Score, word and sentence counts. Results Both Artificial Intelligence tools required college-level understanding for all difficulty levels. Google Gemini was easier to understand ( p = 0.03), while ChatGPT-4 provided more correct answers for the more difficult questions ( p = 0.0005) with fewer serious errors. ChatGPT-4 scored highest on most challenging questions, showing superior thematic accuracy ( p = 0.003). ChatGPT-4 outperformed Google Gemini in 8 of 13 questions, with higher overall quality grades in the easiest ( p = 0.03) and hardest levels ( p = 0.0002), showing a lower grade as question difficulty increased. Conclusions ChatGPT-4 and Google Gemini effectively address queries about retinal detachment, offering mostly accurate answers with few critical errors, though patients require higher education for comprehension. The implementation of AI tools may contribute to improving medical care by providing accurate and relevant healthcare information quickly
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
