Canine Bacterial Endocarditis: A Text Mining and Topics Modeling Analysis as an Approach for a Systematic Review
No full textBacterial endocarditis (BE) is a severe infection of the endocardium and cardiac valves caused by bacterial agents in dogs. Diagnosis of endocarditis is challenging due to the variety of clinical presentations and lack of definitive diagnostic tests in its early stages. This study aims to provide a research literature analysis on BE in dogs based on text mining (TM) and topic analysis (TA) identifying dominant topics, summarizing their temporal trend, and highlighting any possible research gaps. A literature search was performed utilizing the Scopus® database, employing keywords pertaining to BE to analyze papers published in English from 1990 to 2023. The investigation followed a systematic approach based on the PRISMA guidelines. A total of 86 records were selected for analysis following screening procedures and underwent descriptive statistics, TM, and TA. The findings revealed that the number of records published per year has increased in 2007 and 2021. TM identified the words with the highest term frequency-inverse document frequency (TF-IDF), and TA highlighted the main research areas, in the following order: causative agents, clinical findings and predisposing factors, case reports on endocarditis, outcomes and biomarkers, and infective endocarditis and bacterial isolation. The study confirms the increasing interest in BE but shows where further studies are needed
Electrocardiographic Findings and Cardiac Troponin I Assay in Dogs with SIRS Diagnosis
No full textSeveral studies performed in humans have demonstrated that the onset of systemic inflammatory response syndrome (SIRS) represents a high risk condition to develop myocardial damage and arrhythmias. Therefore, we also hypothesized cardiac involment for dogs affected by SIRS. To assess this hypothesis, 24 dogs with a diagnosis of SIRS (13 entire males, 7 entire females, and 4 spayed females) with an age ranging from 4 to 11 years (mean 5.6 years) and an average weight of 24 kg (range from 5 to 47 kg) were enrolled. The dogs were divided into two groups according to their prognosis: Survivors (G1) and not survivors (G2), composed by 13 and 11 dogs, respectively. Moreover, healthy dogs were included as the control group (CTR). All the dogs with a history of cardiac or renal disease were excluded. At the inclusion, each patient underwent a physical examination and a complete cell count, and a biochemistry panel (including electrolyte profile) was performed; moreover, the blood cardiac Troponin I (cTnI) was measured. For each clinical variable indicative of SIRS, a score between 0 (absence) and 1 (presence) was applied. Furthermore, an electrocardiographic examination was recorded. Seventeen out of 24 (70.8%) dogs with SIRS showed arrhythmias, of which n. 6 belonged to the G1, while n. 11 belonged to the G2. Most represented findings were sinus tachycardia (7/17; 41.1%), followed by monomorphic premature ventricular beats (6/17; 35.3%), less common were first-degree atrioventricular block (2/17; 11.7%) and sinus bradycardia 1/17; 5.8%). Notably, in G1 dogs, only sinus tachycardia and premature ventricular beats were observed. G2 dogs presented a number of total and banded leukocytes significantly higher than those of G1 (p = 0.002 and 0.049), in the same manner, the clinical score suggestive of SIRS (3 vs. 2.1) was significantly higher in G2 than in G1 dogs (p = 0.01). Moreover, a significantly higher value of cTnI was observed in the G2 group compared to the G1 group (p = 0.006). Data presented here suggested a cardiac involvement in dogs with SIRS, analogously to humans, that may significantly influence the patient’s prognosis
The comparison of dry foods used in dog nutrition and dietary foods in the treatment of various diseases in terms of element levels
No full textÖnceleri sadece insanların gıda artıklarıyla beslenen köpeklerin gerek insanlarla birlikte yaşamaya başlamaları ve sayılarının artışı, gerekse bakımıyla ilgilenen sahiplerinin sosyal yaşamındaki yoğunluklarıyla birlikte bu mamaların kullanımlarının pratik olması nedeniyle kuru ve yaş mama kullanımı artmakta ve çeşitlenmektedir. Değişik aroma ve protein kaynağı olmasının yanı sıra veteriner hekimler tarafından da tercih edilen çeşitli hastalıkların tedavisinde veya oluşmasında engelleyici rolü olan mamalar da bulunmaktadır. Çalışma kapsamında ülkemizde köpekler için satılmakta olan normal ve reçete edilebilir diyet kuru mamalardaki bazı eser elementlerin (Bakır, Demir, Mangan, Çinko ve Selenyum) belirlenmesi amaçlanmıştır. Bu amaçla reçetesiz satılan farklı aroma ve markadan 50 adet mama kontrol grubunu oluştururken; her biri 25 adet olmak üzere karaciğer hastalıkları, böbrek hastalıkları, gastrointestinal sistem hastalıkları ve alerjik deri hastalıkları tedavilerinde kullanılan reçeteli diyet mamalar toplandı. Tüm örnekler İndüktif Eşleşmiş Plazma-Optik Emisyon Spektroskopisi cihazında ölçülerek, istatistiki değerlendirmeleri yapıldı. Kontrol grubuna göre bakır düzeyleri değerlendirildiğinde gastrointestinal sistem hastalıkları grubu ile alerjik deri hastalıkları gruplarında ortaya çıkan istatistiki yönden anlamlı değişiklikler; demir ile mangan düzeyleri açısından değerlendirildiğinde böbrek hastalıkları grubu dışındaki tüm gruplarda ortaya çıkan istatistiki yönden önemli farklılıklar; çinko açısından sadece alerjik deri hastalıkları grubunda ortaya çıkan istatistiki açıdan anlamlı artış ve selenyum açısından sadece böbrek hastalıkları grubunda ortaya çıkan istatistiki açıdan önemli azalış dikkate değer bulundu. Sonuç olarak hem normal mamalarda hem de reçete edilebilir diyet mamalardaki element düzeylerindeki farklılıkların bilinmesinin uygulanacak tedavi protokolünün belirlenmesi, takip edilmesi ve olası istenmeyen etkilerinin önlenmesi açısından dikkate değer bulunacağı kanısındayız.The use of dry and wet pet foods by the pet owners who are busy with social life has been increasing and showing diversity. The factors contributing to this choice are both its practical use and an increasing number of companion pets which fed with the scraps in the past. Besides the fact that it’s a source of different protein and taste, they are also advised by the veterinarians for their role in helping the treatment of several diseases and their prophylaxis. This study aims to identify some trace element levels (Copper, Iron, Manganese, Zinc, and Selenium) in normal and prescription dry pet foods for dogs in Turkey. For this purpose, non-prescription different branded pet foods (n:50) were used as control groups; prescription foods (each group as n:25) were collected for other groups as the treatment of liver diseases, kidney diseases, gastrointestinal tract diseases and, allergic skin diseases. All samples were measured by using the Inductively Coupled Plasma-Atomic Emission Spectroscopy device and their statistical evaluations were performed. When the copper levels were compared to the control group, statistically significant changes were found in the group of gastrointestinal diseases and allergic skin diseases. In terms of iron and manganese levels, statistically significant differences were observed in all groups except renal disease group. In terms of zinc, the only statistically significant increase in the group of allergic skin diseases and the statistically significant decrease in selenium in the group of kidney diseases were found remarkable. As a result, we believe that knowing the differences in element levels in both normal foods and prescribed foods will be considered in terms of determining the treatment protocol to be applied, monitoring and prevention of possible unwanted effects
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
