Definition of treatment goals in terms of clinician-reported disease severity and patient-reported outcomes in moderate-to-severe adult atopic dermatitis: a systematic review
BACKGROUND: Atopic dermatitis (AD) is a chronically relapsing skin disease. Although a definitive cure is not available, appropriate treatment can control the disease. The advent of biologic drugs has led to the need for a clear definition of the disease severity and treatment response. A standardized list of outcomes that defines clinician-reported disease severity and patients' reported severity are therefore essential. Solid criteria to define the response to treatment and treatment failure are lacking to date.OBJECTIVE: This systematic review defines treatment goals in terms of clinician-reported disease severity and patient-reported outcomes, referring to the published moderate-to-severe AD clinical trials. The application of these goals in daily clinical practice will ensure a better selection of available treatment options, thus increasing patient quality of care.MATERIALS AND METHODS: A systematic literature search was performed to identify the treatments goals of randomized controlled clinical trials (RCTs) on moderate-to-severe adult AD published between January 2000 and October 2020.RESULTS: In total, 14 studies met the eligibility criteria. The most widely used tools in terms of clinician-reported disease severity were the Scoring of Atopic Dermatitis (SCORAD) followed by the Eczema Area Severity Score (EASI) and Investigator Global Assessment (IGA). For disease severity scales as efficacy outcome in RCTs, the greatest standardization and reproducibility was for improvement of at least 50% in EASI score and IGA score reduction of ≥2 grades from baseline. The most widely used tools from the patients' perspective were the Dermatology Life Quality Index (DLQI), Numeric Rate Scale (NRS)-itch and Patient Oriented Eczema Measure Score (POEM). In terms of patients' reported efficacy outcomes in RCTs, a numerical DLQI, NRS-itch and POEM score improvement of at least 4 points from baseline was reported.CONCLUSIONS: This systematic review highlights the need for collaboration between experts in order to define and optimize treatment outcomes. Despite considerable progress in harmonizing outcome measures, promoted by the foundation of the Harmonizing Outcome Measures for Eczema (HOME) initiative in 2008, our results demonstrate that this endpoint is still an unmet need. Based on the literature data we propose a minimum treatment goal algorithm for use in daily clinical practice aimed at stimulating a discussion on how the care of AD patients could be further improved
Dermoscopy for Benign Melanocytic Skin Tumors
In this chapter, we present the dermoscopic clues of the main categories of nevi, making a brief mention of their clinical and histopathological features. Not only junctional, dermal and compound nevi are described, but also congenital, blue, Spitz–Reed, Meyerson’s, desmoplastic, balloon, targetoid hemosiderotic, and sclerosing nevus are described
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
