Global prevalence of burnout in gastroenterology and endoscopy: A systematic review and meta‐analysis
Full text linkBackground
Burnout is an increasingly recognised phenomenon that negatively affects physicians' well-being, patient safety and the sustainability of healthcare systems. In this systematic review and meta-analysis, we aimed to estimate the global prevalence of burnout in gastroenterology and endoscopy.
Methods
We searched Medline, Embase, Scopus and PsycINFO up to November 2024 for studies reporting the prevalence of burnout in gastroenterology and endoscopy. The primary outcome was the prevalence of burnout among gastroenterologists and endoscopists. Secondary outcomes included the prevalence of emotional exhaustion, depersonalisation, low sense of personal accomplishment and gender-related differences in burnout. We used random-effects models to calculate the pooled prevalence and odds ratios (OR) with their 95% confidence intervals (CI).
Results
A total of 22 studies comprising 8124 participants were included. The pooled prevalence of burnout was 45% (95% CI, 37%–54%), with significant variability observed across different geographical regions, assessment tools and definitions of burnout. The pooled prevalence of emotional exhaustion was 31% (95% CI, 22%–40%), depersonalisation was 23% (95% CI, 16%–31%), and low sense of personal accomplishment was 25% (95% CI, 10%–40%). Female gastroenterologists were more likely to experience burnout than males (OR 1.53; 95% CI, 1.16–2.01; p < 0.001).
Conclusions
Almost half of gastroenterologists and endoscopists experience burnout, with females being disproportionately affected. These findings highlight the need for urgent action to address burnout and its contributing factors, including gender disparities
Global prevalence of celiac disease in patients with Rome III and Rome IV irritable bowel syndrome: A systematic review and meta-analysis
Full text linkIntroduction: Irritable bowel syndrome (IBS) and celiac disease (CeD) are common disorders that share overlapping symptoms. In this systematic review and meta-analysis, we aimed to provide up-to-date and comprehensive estimates of the prevalence of CeD in patients with IBS. Methods: We searched several databases through January 2025 for studies reporting the prevalence of CeD in patients with IBS. Eligible studies used Rome III or Rome IV criteria for IBS diagnosis and used serological screening with tissue transglutaminase, endomysial antibodies, or deamidated gliadin peptide, and/or confirmatory duodenal biopsies for CeD diagnosis. We used random-effects meta-analysis to estimate the pooled prevalence of seropositive and biopsy-proven coeliac disease with 95% confidence intervals (CI). We calculated pooled odds ratios (ORs) to compare the likelihood of CeE between patients with IBS and controls. Results: A total of 29 studies comprising 7,209 patients with IBS were included. The pooled seroprevalence of CeD in patients with IBS was 6% (95% CI, 5% - 8%), and the pooled prevalence of biopsy-proven CeD was 2% (95% CI, 2% - 3%). A significant proportion of seropositive patients (15%; 95% CI, 6% - 24%) did not undergo endoscopy and biopsy. Patients with IBS had significantly higher odds of a positive serology than controls (OR 4.42; 95% CI, 2.82 - 6.92). The odds of CeD were similar across genders and IBS subtypes. There was a limited number of studies from Europe and no studies from the United States. Conclusion: CeD is highly prevalent in patients with IBS, according to the Rome III and Rome IV criteria. A positive diagnosis of IBS should not be made without excluding CeD.Introduction Irritable bowel syndrome (IBS) and celiac disease (CeD) are common disorders that share overlapping symptoms.

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
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
