Rectus sheath hematoma in an 80-year-old man with venous leg ulcer infection: a case report
No full textPatients with venous leg ulcers often present with comorbidities that increase the complexity of their care. In elderly patients, acute abdominal pain is frequently caused by intestinal occlusion, gastrointestinal tumors, and abdominal ischemia. We report the case of an 80-year-old man presenting with acute abdominal pain admitted to our unit because of venous leg ulcer infection
Diabetic foot in children and adolescents: The next epidemic? A meta-analysis
No full textAim. Recent estimates of the International Diabetes Federation indicate that 8.3% of adults - 382 million people - have diabetes mellitus (DM), one in two people with diabetes have no awareness of their own disease and the number of people with the DM is set to rise beyond 592 million in 2020. An increased prevalence of type 2 DM (T2DM) in children has been reported worldwide. Foot disorders result in major long-term complications for diabetic patients. Increased risks for lower limb amputation in adults have been associated with peripheral neuropathy with loss of protective sensation, peripheral vascular disease, altered biomechanics. There are few reports concerning foot problems in any pediatric cohort. The aim of this meta-analysis was to review the current literature on foot problems in children and adolescents with DM. Methods. A systematic review was performed on all articles published from January 1980 to August 2014 and listed in MEDLINE, EMBASE, CENTRAL, and in hand-searched reference lists from all identified articles. We searched the terms: "foot" AND "pediatric" AND "children" AND "diabetes mellitus". Results. The international guidelines recommend that children with diabetes have their feet examined since puberty and then at least annually for protective sensation, pulses, skin integrity, and treatable nail problems such as ingrown toenails. Some authors have reported that many young patients with DM have foot problems and evidence of early manifestation of peripheral neuropathy in adolescents with T2DM. Conclusion. By t this research we wanted to highlight the importance of foot examination and foot care advice for children and adolescents with diabetes. Larger prospective studies are required to establish prevalence and to optimize preventive interventions
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
