Clinical aspects and comorbidities of Psoriasis
Psoriasis is a disease mediated by Th1 and Th17 cytokines that has different phenotypes (plaque, guttate, pustular, and erythrodermic type). Aside from the well known psoriatic arthritis, associated disorders may occur more frequently than expected, including Crohn's disease, anxiety/depression, and metabolic syndrome. This is based on a constellation of different factors, including abdominal obesity, atherogenic dyslipidemia, hypertension, and glucose intolerance, and is a strong predictor of type 2 diabetes, cardiovascular disease, and stroke. People with moderate to severe psoriasis have more risk for cardiac disease, presumably due to the inflammatory nature of psoriasis, causing inflammatory changes in coronary arteries. The strong association between psoriasis and obesity potentially makes psoriasis an important healthcare issue. Since cardiovascular risk factors are higher in psoriatic patients, dermatologists treating moderate to severe psoriasis should screen for their presence, thus approaching psoriasis as a potential multisystem disorder
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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
Psoriasi, farmaci e abitudini personali: studio su 615 pazienti
Background: psoriasis is a chronic, multifactorial inflammatory disease that affects about 3% of the general population. This disease is thought to be induced or aggravated by several factors, including excessive alcohol intake, physical and psychological stress, and drugs. Several drugs can interfere with psoriasis in predisposed individuals, even if a family history of psoriasis is absent. The more suspected drugs include lithium, β-blockers, antimalarials and nonsteroidal anti-inflammatory drugs (NSAID). The association between alcohol and psoriasis is complex and confusing because many of the initial studies did not control for confounding factors such as tobacco use. Early studies showed no correlation between alcohol consumption and psoriasis. However, as researchers began to control for confounding factors, the results of many studies often showed a significant correlation between alcohol intake and psoriasis. Some studies suggested a relative risk factor of 8.01, particularly in men; these studies did not document an increased risk for psoriasis in women drinking alcohol. Smoking is a risk factor for psoriasis and seems to be associated with the clinical severity of psoriasis. Materials and Methods: we conducted a case-control study to analyse the association between psoriasis and some risk factors for psoriasis, including smoking habits, spirit consumption and drugs. The study was conducted by comparing a group of 615 patients (308 women and 307 men) affected by psoriasis with a group of 900 control subjects (459 women and 441 men). Results: our study shows that smoking constitutes a risk factor in the development of psoriasis. Moreover, we found a dose-response association between smoking and psoriasis. The risk of psoriasis was higher in ex- and current smokers than in non smokers. The relative risk estimates (OR) is 2.6 for ex-smokers and 1.3 for smokers. Our study found an association between smoking and the vulgaris variant of psoriasis but unlike other authors, we did not find any association between smoking and pustular psoriasis. Conclusions: our study confirms the relationship between some drugs and onset/aggravation of psoriasis. Lithium (OR = 5.2), β-blockers and anti-malarials (OR = 3.9), interferons (OR = 3.3), sartans (OR = 3.2) and nonsteroidal antinflammatory drugs (OR = 3.0) were variously associated with a personal history of psoriasis
