Stemming the "ageism pandemic": A qualitative inquiry with older adults in residential care facilities during the Covid-19 outbreak
No full text: The Covid-19 pandemic added to collective concerns, making health risks salient especially for the older population. The health emergency exacerbated an already widespread negative representation of aging, and phenomena such as ageism. With the present qualitative inquiry, 21 episodic interviews were collected with the aim of understanding the experience of older adults in residential care facilities, exploring their ideas of aging and the viewpoints that helped them to respond to the pandemic successfully. A thematic analysis was conducted using NudIst software. The results show that participants described multiple personal and relational resources they used to cope with the pandemic, and they were able to express counter-narratives to the ideas of aging as coinciding with decline, and of lockdown as a source of distress alone. The paper concludes with reflections on the relevance of research capable of challenging unhelpful dominant discourses and averting the risk of them turning into negative prophecies
Retention Rate, Persistence and Safety of Adalimumab in Inflammatory Bowel Disease: A Real-Life, 9-Year, Single-Center Experience in Italy
No full textBackground: "Real-life" data of retention rate and persistence of adalimumab in inflammatory bowel disease are still limited.
AIMS:
To analyze retention rate, persistence, and safety of adalimumab in a 9-year real-life cohort of inflammatory bowel disease patients.
METHODS:
In this observational, retrospective single-center study, all adult patients treated with adalimumab as the first- and second-line biological treatment for steroid-dependent or refractory inflammatory bowel disease between March 2008 and March 2017 were included. Primary outcomes were persistence, retention rate, and adverse events; the secondary outcome was the identification of predictors of withdrawal.
RESULTS:
Ninety-six out of 181 patients (53%) withdrew their first course of adalimumab. The retention rate was 47% and 46.9% in Crohn's disease and ulcerative colitis patients, respectively; median persistence was 26 and 24 months in CD and UC patients, respectively. The cumulative probability of treatment persistence was 80.2%, 54.5%, and 29.6% and 69.6%, 40.4%, and 21.5% in CD and UC patients, respectively. The incidence rate of any adverse event was 12.5/100 patients-year; severe adverse events were 1.7/100 patients-year. The Cox regression revealed that CD patients with baseline disease duration > 72 months have a higher likelihood for withdrawal due to failure and/or adverse events (HR 1.62, 95% CI 1-2.62, p = 0.04); no predictors of discontinuation were found in UC.
CONCLUSIONS:
Adalimumab showed a great persistence in the first 12 months of therapy and excellent safety profile. Early treatment of CD patients could increase efficacy and reduce the adverse event rate
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
Eicosapentaenoic Acid Reduces Fecal Levels of Calprotectin and Prevents Relapse in Patients With Ulcerative Colitis
No full textBackground & Aims: High fecal levels of calprotectin indicate mucosal inflammation and have been shown to predict relapse in patients with ulcerative colitis (UC). Eicosapentaenoic acid (EPA), the major component of n-3 fish oil, has anti-inflammatory properties in patients with chronic inflammatory disorders. We performed a placebo-controlled trial of patients with UC at risk of relapse to determine the ability of the free fatty acid form of EPA (EPA-FFA) to reduce intestinal inflammation, using fecal level of calprotectin as a marker. Methods: From June 2014 to May 2016, 60 patients with UC with a partial Mayo score < 2 and fecal calprotectin ≥150 μg/g, in stable therapy for at least the 3 previous months, were randomly assigned to groups (1:1) given either EPA-FFA (500 mg, twice daily) or placebo for 6 months. A colonoscopy was performed at baseline. Clinical assessments and measurements of fecal calprotectin were made at baseline, at study months 3 and 6, or the time of clinical relapse. Patients with a relapse of UC underwent a second colonoscopy. The primary end point was a 100-point reduction in fecal levels of calprotectin at 6 months from the baseline value; the secondary end point was maintenance of clinical remission at 6 months. Results: The primary end point was achieved by 19 of 30 patients (63.3%) in the EPA-FFA group vs 4 of 30 patients (13.3%) in the placebo group (odds ratio, 12.0; 95% CI, 3.12–46.24; P <.001). The secondary end point was achieved by 23 of 30 patients (76.7%) in the EPA-FFA group vs 15 of 30 (50%) patients in the placebo group (OR, 3.29; 95% CI, 1.08–9.95; P =.035). No serious adverse events were observed. Conclusions: In a placebo-controlled trial of 60 patients with UC, we found 6 months’ administration of EPA-FFA to reduce fecal levels of calprotectin with no serious adverse events. This agent might be used to induce and maintain symptom-free remission in patients with UC. ClinicalTrials.gov number: NCT02179372
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
