Open heart surgery in a patient with liver transplantation: A case report
No full textKaraciğer nakli olan hasta sayısı arttıkça, geç dönemde gelişen kalp ve diğer sistem patolojileri Damar Cerrahisi Kliniği, Florya, İstanbul, nedeniyle cerrahi uygulamaları da sıklaşmıştır. Karaciğer nakli olan hastalarda koroner arter hastalığının görülme oranı artmaktadır. Karaciğer transplantı hastaları, asemptomatik olsa bile, koroner arter hastalığı için yüksek risk alt grubudur. Karaciğer transplantı gerçekleştirilen bir Turkey. hastada koroner arter hastalığı gelişmesi, kötü bir prognostik faktördür; Bu nedenle, risk altındaki kişilerin belirlenmesi klinik önceliğe sahip olmalıdır. Bu çalışmamızda, on iki yıl önce karaciğer nakli uygulanan 68 yaşındaki bir erkek hastaya iskemik kalp hastalığı tanısı ile kardiopulmoner Çıkar Çatışması: Yazarlar çıkar çatışması.As the number of patients with liver transplantation increased, surgical applications were also frequent due to late-onset heart and other systemic pathologies. The incidence of coronary artery disease is increasing in patients with liver transplantation. Liver transplanted patients are a high risk subgroup for coronary artery disease, even if they are asymptomatic. Coronary artery disease is a predictor of poor outcomes in patients with liver transplantation; therefore, identiŞcation of those Sorumlu yazar / Corresponding author patients at risk for coronary artery disease should be a key clinical priority. In this study, it was Melike Elif Teker aimed to present coronary artery bypass grafting surgery in a 68-year-old male patient with previous ve Damar Cerrahisi Hastanesi, Eski Londra Asfaltı liver transplantation 12 years ago. Coronary artery bypass grafting operation was performed using left internal mammarian artery and autogenous vein graft for three vessels. There was no complication in the pre- and post-operative periods. Coronary artery bypass grafting operation can be performed safely for patients with previous liver transplantaion in experienced centers
Hemodializ planlanan çocuklarda arteriovenöz fistül uygulamasının uzun dönem sonuçları
Full text linkGiriş ve Amaç: Erişkinlerde olduğu gibi çocuklarda da kronik böbrek yetmezliği varlığında ideal tedavinin renal transplantasyon olduğu düşünüldüğünden, transplantasyon müdahalesine kadar temel tedavi hemodiyalizdir. Hemodializ programının başarısı da iyi bir vasküler yolun varlığına bağlıdır. Bu prospektif çalışmamızda hemodializ programına alınan 32 çoçukta yapılan 47 damarsal girişimi sunduk. Yöntem ve gereçler: Ocak 2014-Ocak 2016 tarihleri arasında hemodializ programına başlayacak 32 çocuk hastaya 47 vasküler girişim uygulandı. Olguların 11’ine radiosefalik, 22’sina brakiosefalik ve 14’üne ise brakiobazilik fistül açıldı. Arteriovenöz (A-V) fistüller 3 ay ile 2 yıl arasında olmak üzere ortalama 18,1±14,1 ay takip edildi Bulgular: Fistüllerin fonksiyon görme süresi ortalama 18,6±15,3 ay olarak bulundu. Radiosefalik fistül yapılan 5 olguda, brakiosefalik yapılan 2 olguda fistül trombozu nedeniyle yeniden fistül yapıldı. Olguların 1’inde enfeksiyon görüldü ve verilen medikal tedaviyle gerilediği saptandı. Üç olguda ise fistül anevrizması gelişti ve anevrizmatik ven bağlanıp diğer koldan yeni fistül yapıldı. Konjestif kalp yetersizliği (KKY), nöropati, venöz hipertansiyon hiçbir hastada gözlenmedi. Tartışma ve sonuç: Çocuklarda hemodiyaliz için seçilen vasküler yolların sonuçları ve komplikasyonları erişkinlerdeki vasküler girişimsel yöntemlerle benzerlik göstermektedir. Çocuklarda iyi bir teknik ile fistülün oluşturulması halinde, fistülün çalışma oranı yüksek, infeksiyon ve hematom oluşma olasılığı düşüktür. Deneyimli bir cerrahi ekip tarafından oluşturulan A-V fistüllerin multidisipliner bir yaklaşımla dikkatli izlenmesi ve vasküler yapıların akılcı kullanılması, bunların uzun süre fonksiyon görmesini sağlayacağı düşünüldü.Introduction: Like adults, children with chronic renal failure require hemodialysis as the main treatment while waiting for renal transplantation. The success of hemodialysis depends on a good vascular route. In this prospective study, 47 vascular interventions are presented in 32 children included in a hemodialysis program. Methods: Between January 2014 and January 2016, 47 vascular interventions were conducted in 32 children who were planned for hemodialysis. Radiocephalic fistula was performed in 11, brachiocephalic fistula in 22, and brachiobasilic fistula in 14 patients. Arteriovenous (AV) fistulas were followed-up between 3 months and 5 years (average, 18.1±14.1 months). Results: The functional time of fistulas was approximately 18.6±15.3 months. Five radiocephalic fistulas and two brachiocephalic fistulas were redone because of fistula thrombosis. Wound infection was observed in 1 patient who recovered with medical treatment. In 3 patients, fistula aneurysm was observed. The aneurysmal vein was ligated, and a new fistula was performed on the other arm. Congestive heart failure, neuropathy, and venous hypertension were not observed in any patient. Discussion and conclusion: The results and complications of vascular intervention for hemodialysis in children are same as those in adults. If a good technique is applied in children, the functional rate of the fistula will be higher and the rate of infection and hematoma will be lower. We believe that if AV fistulas, which were performed by an experienced surgery team, are carefully followed-up using a multidisciplinary approach, and if vascular structure is used rationally, the fistulas will be functional for a longer time
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
