Résumé
Objective: Representing diverse perspectives in medical publications is of great importance. We assessed diversity among investigators, study participants, authors and tweeters of recent publications on COVID-19 vaccine trials, a topic likely to have significant global implications. Research design and methods: Primary publications reporting on COVID vaccine randomized controlled trials (RCTs) were identified via PubMed (n=302 hits, 23 September 2022). The 100 articles with the greatest impact (Altmetric score) were selected for evaluation. National affiliation of authors and investigators, and demographics of participants were collected. Geographic locations of Tweets mentioning the publications were collected via Altmetric. Result(s): In our preliminary analysis, as expected, selected publications most frequently appeared in top-tier journals, e.g. New England Journal of Medicine (n=24) and Lancet (n=19), and had high Altmetric scores (median 886, range 30-29,153). Articles included authors from mean 2.2 countries, most frequently the USA (n=43 articles), the UK (n=31) and China (n=23). Investigators' locations were often not reported, but most frequent were the UK (n=2711 investigators), USA (n=1029) and South Africa (n=269). There was a gender balance among participants across the studies (mean 49.4% female). The most frequent ethnic groups were white, Hispanic and Asian. Tweets mentioning the publications most commonly came from the USA (8.1%), the UK (3.1%) and Japan (2.9%). Conclusion(s): Despite COVID-19 being a global health emergency, most authors, investigators and readers of high impact COVID-19 vaccine RCT publications were from a small group of countries, with some notable exceptions. Numerous studies did not report the geographic location of investigators or participant ethnicity. Consistent and transparent reporting would support the drive towards greater diversity and representation in medical research.
Résumé
Introduction Previous studies have reported ongoing cardiac inflammation as assessed by cardiac magnetic resonance imaging (CMR) in a significant proportion of patients several months after recovery from SARS-CoV-2 infection, many of whom had no or minimal symptoms at the time of infection. The aim of SETANTA was to investigate the prevalence of cardiac abnormalities by CMR in unselected patients in Ireland after acute SARS-CoV-2 infection and the correlation with immunological response and biomarkers of coagulation. Methods This was a prospective, observational, communitybased study (clinicaltrials.gov identifier NCT04823182). Consecutive patients recovered from recent SARS-CoV-2 infection at 3 primary care sites were invited to participate. Key inclusion/ exclusion criteria and outcomes of interest are shown in figure 1. Results 100 participants were enrolled (Feb-Sept 2021) at a median of 188 (IQR, 125, 246) days after positive SARSCoV- 2 swab. At index infection, 18% and 35% reported severe and moderate symptoms, respectively;14% were hospitalized;3% were admitted to intensive care for ventilatory support. At enrolment, 83% had ongoing symptoms. 85% had detectable SARS-CoV-2 antigens. CMR and laboratory findings are shown in Figure 1. Clinical follow up to 12 months is ongoing. Conclusion Among an unselected cohort of patients recovered from acute SARS-CoV2 infection, we report a low prevalence of cardiac abnormalities by CMR, despite a high prevalence of moderate/severe symptoms at presentation and a high prevalence of persistent symptoms. Correlation with biomarkers of immunity and coagulation add results of follow up at 12 months will be available for presentation at ICS 2022.
