Comparison of Pain Location and Extent Between Adults with Ankylosing Spondylitis-related Inflammatory versus Chronic Nonspecific Low Back Pain
No full textIntroduction: Pain among adults with ankylosing spondylitis-related inflammatory low back pain (AS-ILBP) is not well-characterized, and individuals with AS-ILBP are frequently misdiagnosed with chronic nonspecific low back pain (CNSLBP). This study digitally quantifies and compares the location and extent of pain between adults with AS-ILBP and those with CNSLBP and examines the relationship between the pain extent and functional, psychological, and condition-specific factors in those with AS-ILBP.
Methodology: The location and extent of pain in adults with AS-ILBP (n = 27) or CNSLBP (n = 22) was quantified using a digital pain drawing analysis. Relationships between pain extent and perceived pain intensity and disability, pain-related cognitive factors (back beliefs, fear of movement, pain catastrophizing, pain coping, and self-efficacy), psychological distress, and AS-specific features were examined in those with AS-ILBP.
Result: Pain extent in the dorsal region of the body was greater in those with AS-ILBP than in CNSLBP (P 0.05). The AS-ILBP group more frequently reported pain in the thoracic (70.4%) and cervical (51.8%) regions (P < 0.05). In the AS-ILBP group, larger pain extent was moderately associated with negative back beliefs (rs = –0.44 to –0.41, P < 0.05) and lower self-efficacy (rs = –0.58 to –0.42, P < 0.05), but not with any of functional outcomes. Larger pain extent was associated with higher disease activity (P < 0.05).
Conclusion: Adults with AS-ILBP perceive larger pain extent in spinal regions and the degree of pain extent is associated with negative back beliefs, lower self-efficacy, and higher disease activity. Pain drawings may assist in the differential diagnosis of CNSLBP and AS-ILBP. Further, they may aid psychological screening in adults with AS-ILBP
Experiences of Adults Living with Ankylosing Spondylitis-related Inflammatory Low Back Pain: A Qualitative Study
No full textIntroduction: Inflammatory low back pain (ILBP) is a key clinical symptom and a significant problem in ankylosing spondylitis (AS), its high socioeconomic costs are mainly attributed to disability. To the best of our knowledge, no study has specifically explored the ILBP experience in adults with AS. This study aimed to explore the experiences of ILBP from the perspective of adults with AS.
Methodology: This study followed a qualitative descriptive design. Participants were recruited from rheumatology and physiotherapy outpatient clinics of two major hospitals in Dublin, and from AS patient support groups in Ireland. A total of 19 adults with AS-related inflammatory low back pain (AS-ILBP) (mean age 47.8 years [SD 11.2]) participated in semi-structured face-to-face interviews. All interviews were audio-recorded, transcribed verbatim, coded, and analyzed thematically.
Result: Analysis of experiences revealed five themes: (i) experiences and perception surrounding diagnosis, (ii) perceived ILBP trajectories, (iii) impact of AS-ILBP, (iv) behavioral responses toward ILBP, and (v) experience with AS-ILBP treatments. Adults with AS-ILBP experienced a delay in diagnosis, in which ILBP was negatively perceived, and dysfunctional LBP beliefs and behaviors were reported. ILBP appeared to have a multidimensional nature and impact, with the greatest impact suggested on physical function and psychological health. Many individuals with AS held negative ILBP beliefs that drove dysfunctional behaviors. The primary received ILBP treatment was medication and to a lesser extent physiotherapy; both described treatments had limited effects.
Conclusion: This study was the first to reveal the unique experience of ILBP from the perspective of adults with AS. AS-ILBP appear to have a varying course and a multidimensional associated factors that determine its trajectory. AS-ILBP was suggested to affect all aspects of individual's life. A bidirectional relationship between ILBP and the psychosocial factors was proposed; these factors were perceived as aggravators and consequences of ILBP. This study also points to the limitations of current AS-ILBP management, which were mainly biomedically oriented. Thus, healthcare providers are advised to incorporate a multidimensional pain screening with their routine physical assessments of adults with AS-ILBP. This could help in designing tailored individualized, effective AS-ILBP management programs
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
