Incidence and prevalence of generalized pustular psoriasis in multi-ethnic Johor Bahru, Malaysia: a population-based cohort study using routinely captured electronic health records from 2010 to 2020. Supplementary materials
No full textSupplemental Tables and figures of manuscript entitled "Incidence and prevalence of generalized pustular psoriasis in multi-ethnic Johor Bahru, Malaysia: a population-based cohort study using routinely captured electronic health records from 2010 to 2020"We used data drawn from our local clinical information system, which links primary and secondary care facilities and has captured over 98% of the population in Johor Bahru, to estimate the incidence and prevalence of dermatologist diagnosed GPP over 11 years and examine the frequency of GPP flares and trigger factors. We show that:1.the incidence and prevalence of GPP in Johor Bahru was 27.2 per million person years (95% CI 22.8-31.6) and 198 per million, respectively;2.incidence and prevalence of GPP varied by age, sex, ethnicity and presence of associated psoriasis vulgaris;3.common trigger factors of GPP included withdrawal of systemic corticosteroids, infections, and use of traditional medicines;4.flare frequency and trigger factors varied between GPP patients with and without associated psoriasis vulgaris

Clinico-epidemiological profile, including body mass index of Malaysian children with psoriasis
No full textbackground: Limited information exists regarding paediatric
psoriasis and its association with body mass index (bMI) in
Asia.
Objectives: to determine the clinico-epidemiological profile
and to compare the bMI of children with and without
psoriasis.
Methods: A case-control study of 92 children with psoriasis
versus 59 with atopic eczema and 56 with non-inflammatory
skin conditions.
results: Psoriasis was more common in Malay and Indian
children when compared to Chinese with odds ratios (Or) of
4.30 (95% CI, 1.85-9.99) and 3.00 (95% CI, 1.02-8.81)
respectively. Prevalence of psoriasis was similar between
Malay and Indian children (Or 1.43, 95% CI, 0.63-3.25).
Male:female ratio was 1:1.09. the mean onset age of
psoriasis was 7.9 years. Median onset age was earlier in
males (6.5 years versus 9.0 years in females, p=0.05).
Plaque psoriasis was the most common phenotype (89.1%)
and 94.5% had scalp lesions. Arthritis was seen in 4.3%.
Odds of excess adiposity, defined as bMI ?85th percentile,
was higher in children with psoriasis versus noninflammatory
controls (Or 2.35, 95% CI 0.99-5.56, p= 0.052).
No increased risk of adiposity was noted between children
with psoriasis and eczema (Or 1.14, 95% CI 0.5-2.62,
p=0.753). More children with psoriasis (17.4%) and eczema
(20.3%) were underweight (bMI <5th percentile) compared to
non-inflammatory controls (10.7%).
Conclusion: Malays and Indians are three to four times more
likely than Chinese to have psoriasis in multi-ethnic
Malaysia. Plaque psoriasis is the most common phenotype.
Odds of excess adiposity is about two times higher in
children with psoriasis compared to non-inflammatory
controls although this observation just missed conventional
statistical significance
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
