Background: The gender gap in the authorship of scientific research may affect career advancement. Our aim was to assess the potential gender gap in gastrointestinal (GI) journals., Methods: A systematic review was performed of the GI literature and ongoing research in the period 2020-2022. A total 10 GI journals and ongoing research on clinicaltrials.gov were selected for review. The gender gap in first and senior authorship was evaluated for each article and ongoing research project. Associations between the gender gap and possible predictors were measured and results are presented as odds ratios (ORs) with 95%CI., Results: The number of first female authors (FFAs) and senior female authors (SFAs) in published articles were 1408/4207 (33.5%) and 911/4207 (21.7%), respectively. There were 781/2654 (29.4%) female principal investigators (PI)s for the ongoing research. On comparison of non-endoscopic vs. endoscopic topics, the latter were associated with the gender gap (hepatology, OR 2.15 [95%CI 1.83-2.55]; inflammatory bowel disease, OR 2.12 [95%CI 1.60-2.45]; upper and lower GI, OR 1.31 [95%CI 1.18-1.73]); as well as the type of article (original article vs. editorial, OR 1.92 [95%CI 1.58-2.33]). The type of research was also associated with the gender gap (clinical vs. preclinical studies, OR 0.88 [95%CI 0.66-0.91])., Conclusion: Our results demonstrated a correlation between the gender gap and the design and topic of the research. Future strategies for improving equity in career development in GI endoscopy should focus on closing the gender gap in equity of authorship., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Background: Chagas disease (CD) is a systemic parasitic infection caused by the protozoan Trypanosoma cruzi, whose chronic phase may lead to cardiac and intestinal disorders. Endemic in Latin America where it is transmitted mainly by vectors, large-scale migrations to other countries have turned CD into a global health problem because of its alternative transmission routes through blood transfusion, tissue transplantation, or congenital. Aim of this study was to compare the performance of two commercially available tests for serological diagnosis of CD in a group of Latin American migrants living in a non-endemic setting (Rome, Italy). The study was based on a cross-sectional analysis of seroprevalence in this group. Epidemiological risk factors associated to CD were also evaluated in this study population., Methods: The present study was conducted on 368 subjects from the Latin American community resident in Rome. Following WHO guidelines, we employed a diagnostic strategy based on two tests to detect IgG antibodies against T. cruzi in the blood (a lysate antigen-based ELISA and a chemiluminescent microparticle CMIA composed of multiple recombinant antigens), followed by a third test (an immunochromatographic assay) on discordant samples., Results: Our diagnostic approach produced 319/368 (86.7%) concordant negative and 30/368 (8.1%) concordant positive results after the first screening. Discrepancies were obtained for 19/368 (5.2%) samples that were tested using the third assay, obtaining 2 more positive and 17 negative results. The final count of positive samples was 32/368 (8.7% of the tested population). Increasing age, birth in Bolivia, and previous residence in a mud house were independent factors associated with T. cruzi positive serology., Conclusions: Serological diagnosis of CD is still challenging, because of the lack of a reference standard serological assay for diagnosis. Our results reaffirm the importance of performing CD screening in non-endemic countries; employing a fully automated and highly sensitive CMIA assay first could be a cost- and resource-effective strategy for mass screening of low-risk patients. However, our results also suggest that the WHO strategy of using two different serological assays, combined with epidemiological information, remains the best approach for patients coming from endemic countries.
