ABSTRACT
The COVID-19 pandemic has highlighted how infodemics (defined as an overabundance of information, including misinformation and disinformation) pose a threat to public health and could hinder individuals from making informed health decisions. Although public health authorities and other stakeholders have implemented measures for managing infodemics, existing frameworks for infodemic management have been primarily focused on responding to acute health emergencies rather than integrated in routine service delivery. We review the evidence and propose a framework for infodemic management that encompasses upstream strategies and provides guidance on identifying different interventions, informed by the four levels of prevention in public health: primary, secondary, tertiary, and primordial prevention. On the basis of a narrative review of 54 documents (peer-reviewed and grey literature published from 1961 to 2023), we present examples of interventions that belong to each level of prevention. Adopting this framework requires proactive prevention and response through managing information ecosystems, beyond reacting to misinformation or disinformation.

Recognition of misinformation as a public health threat and interest in infodemics, defined as an inundation of information accompanying an epidemic or acute health event, have increased worldwide. However, scientists have no consensus on how to best define and identify misinformation and other essential characteristics of infodemics. We conducted a narrative review of secondary historical sources to examine previous infodemics in relation to four infectious diseases associated with pandemics (ie, smallpox, cholera, 1918 influenza, and HIV) and challenge the assumption that misinformation is a new phenomenon associated with increased use of social media or with the COVID-19 pandemic. On the contrary, we found that the spread of health misinformation has always been a public health challenge that has necessitated innovative solutions from medical and public health communities. We suggest expanding beyond the narrow scope of addressing misinformation to manage information ecosystems, defined as how people consume, produce, interact with, and behave around information, which include factors such as trust, stigma, and scientific literacy. Although misinformation can spread on a global scale, this holistic approach advocates for community-level interventions that improve relationships and trust between medical or public health entities and local populations.
ABSTRACT
PURPOSE: We have evaluated the final-year Psychiatry and Addiction Medicine (PAM) summative Objective Structured Clinical Examination (OSCE) examinations in a four-year graduate medical degree program, for the previous three years as a baseline comparator, and during three years of the COVID-19 pandemic (2020-2022). METHODS: A de-identified analysis of medical student summative OSCE examination performance, and comparative review for the 3 years before, and for each year of the pandemic. RESULTS: Internal reliability in test scores as measured by R-squared remained the same or increased following the start of the pandemic. There was a significant increase in mean test scores after the start of the pandemic compared to pre-pandemic for combined OSCE scores for all final-year disciplines, as well as for the PAM role-play OSCEs, but not for the PAM mental state examination OSCEs. CONCLUSIONS: Changing to online OSCEs during the pandemic was related to an increase in scores for some but not all domains of the tests. This is in line with a nascent body of literature on medical teaching and examination following the start of the pandemic. Further research is needed to optimise teaching and examination in a post-pandemic medical school environment.

Governments, public health authorities, and social media platforms have employed various measures to counter misinformation that emerged during the COVID-19 pandemic. The effectiveness of those misinformation interventions is poorly understood. We analyzed fifty papers published between January 1, 2020, and February 24, 2023, to understand which interventions, if any, were helpful in mitigating COVID-19 misinformation. We found evidence supporting accuracy prompts, debunks, media literacy tips, warning labels, and overlays in mitigating either the spread of or belief in COVID-19 misinformation. However, by mapping the different characteristics of each study, we found levels of variation that weaken the current evidence base. For example, only 18 percent of studies included public health-related measures, such as intent to vaccinate, and the misinformation that interventions were tested against ranged considerably from conspiracy theories (vaccines include microchips) to unproven claims (gargling with saltwater prevents COVID-19). To more clearly discern the impact of various interventions and make evidence actionable for public health, the field urgently needs to include more public health experts in intervention design and to develop a health misinformation typology; agreed-upon outcome measures; and more global, more longitudinal, more video-based, and more platform-diverse studies.

Firearm-related injury and death is a serious public health issue in the U.S. As more Americans consume news and media online, there is growing interest in using these channels to prevent firearm-related harms. Understanding the firearm-related narratives to which consumers are exposed is foundational to this work. This research used the browsing behavior of a representative sample of American adults to identify seven firearm-related content "ecosystems" (defined as naturally occurring networks of channels watched by the same users) on YouTube; we then described the demographics and internet search patterns of users affiliated with each ecosystem. Over the 9-month study period, 72,205 panelists had 16,803,075 person-video encounters with 7,274,093 videos. Among these, 282,419 were related to firearms. Using fast greedy clustering, we partitioned users and channel interactions into seven distinct channel-based content ecosystems that reached more than 1/1000 YouTube users per day. These ecosystems were diverse in reach, users, and content (e.g., guns for self-protection, guns for fun). On average, 0.5% of panelists performed a firearm-related internet search on a given day. The vast majority of searches were related to mass shootings or police-involved shootings (e.g., "active shooter"), and virtually none were about more common firearm harm such as suicide. Searches for firearm safety information were most common among panelists affiliated with the "Hunting & Fishing" and "Guns & Gear" ecosystems, which were watched primarily by older, white men. These findings identify an opportunity for analyzing firearm-related narratives and tailoring firearm safety messaging for users affiliated with specific online content ecosystems.

BACKGROUND: In April 2020, the World Health Organization (WHO) Information Network for Epidemics produced an agenda for managing the COVID-19 infodemic. "Infodemic" refers to the overabundance of information-including mis- and disinformation. In this agenda it was pointed out the need to create a competency framework for infodemic management (IM). This framework was released by WHO on 20th September 2021. This paper presents the WHO framework for IM by highlighting the different investigative steps behind its development. METHODS: The framework was built through three steps. Step 1 included the preparatory work following the guidelines in the Guide to writing Competency Framework for WHO Academy courses. Step 2 was based on a qualitative study with participants (N = 25), identified worldwide on the basis of their academic background in relevant fields of IM or of their professional experience in IM activities at the institutional level. The interviews were conducted online between December 2020 and January 2021, they were video-recorded and analyzed using thematic analysis. In Step 3, two stakeholder panels were conducted to revise the framework. RESULTS: The competency framework contains four primary domains, each of which comprised main activities, related tasks, and knowledge and skills. It identifies competencies to manage and monitor infodemics, to design, conduct and evaluate appropriate interventions, as well as to strengthen health systems. Its main purpose is to assist institutions in reinforcing their IM capacities and implementing effective IM processes and actions according to their individual contexts and resources. CONCLUSION: The competency framework is not intended to be a regulatory document nor a training curriculum. As a WHO initiative, it serves as a reference tool to be applied according to local priorities and needs within the different countries. This framework can assist institutions in strengthening IM capacity by hiring, staff development, and human resources planning.

OBJECTIVE: We describe the planning, process and evaluation of final-year Psychiatry and Addiction Medicine summative assessments in a four-year graduate medical degree program, during a COVID-19 Delta-variant public health stay-at-home lockdown. CONCLUSIONS: We conducted separate written and clinical synchronous (real-time simultaneous) tele-assessments. We used online assessment technology with students, examiners and simulated patients, all in different physical locations. Medical students' examination performance showed a good range. This was comparable to other discipline stations, and performance in previous years. There was no differential performance of students through the day of the assessments.

We present a case of an adult male with a solitary mast cell tumor of the skin with unusual nuclear pleomorphism and mitotic activity. The tumor was excised, recurred within 2 years, was reexcised after 4 years and did not recur >6 years after diagnosis. The tumor showed progressive cytonuclear atypia and a high mitotic and proliferation rate by Ki67-staining from the onset. No KIT mutations were identified in the tumor and bone marrow. Serum tryptase levels and a bone marrow aspirate and trephine biopsy were normal. Although the histomorphology of the skin tumor was consistent with mast cell sarcoma, the clinical behavior without systemic progression argued against this diagnosis. The tumor was finally considered as atypical mastocytoma, borderline to mast cell sarcoma. Currently, the patient is in close follow-up and still in complete remission.

OBJECTIVE: To describe and share with the medical education community, the conduct and evaluation of summative graduate medical student assessments in Psychiatry and Addiction Medicine during COVID-19 at an Australian university. METHODS: Summative assessments were redesigned as follows: written assessments were administered via an online platform (WATTLE), while the Objective Structured Clinical Examinations (OSCE) were conducted via a secure video-conferencing software (Zoom). RESULTS: Our preliminary analysis of the summative assessments indicated that both examiners and students adapted to the format, with overall performance of the students showing no variation due to timing of the assessment (earlier versus later in the day) and performances similar to face-to-face assessments in previous years. Examiners also expressed positive feedback on the assessment process. CONCLUSIONS: Our graduate fourth-year medical student summative assessments were effectively conducted using online and video-conferencing software in accordance with existing COVID-19 pandemic public health measures for physical distancing and hygiene.

The aim of this study was to analyze the epidemiology in the bacteriological profile and susceptibility of clinically relevant bacterial pathogens in a burn center in the Netherlands over a 7-year period. The swab results of 693 patients of the period 2005 to 2008 and 539 patients of the period 2009 to 2011 were studied for change of microorganisms and antibiotic resistance. Definitions according to the Working Party on Infection Prevention were used as a tool for assessing the scale of the resistance problem at a local level. Between the studied periods only small changes were found in the bacteriological profile. Staphylococcus aureus showed a slight increase of prevalence in inventory swabs during the second period. In both inventory and wound swabs, S. aureus is the most frequently isolated clinically relevant bacterial pathogen. Resistance for ciprofloxacin in Escherichia coli increased from 3% in 2005 to 2008 to 7% in 2009 to 2011 (P = .028). Resistance for cefotaxim in E. coli increased from 4% in 2005 to 2008 to 14% in 2009 to 2011, although this decrease was not statistically significant (P = .24). The prevalence of highly resistant microorganisms (HRMOs) remained low in both time periods, 4.9% in 2005 to 2008 and 7.4% in 2009 to 2011 (P = .063). The Netherlands is considered a low-prevalence country for antimicrobial resistance, and the occurrence of HRMOs in our center is relatively rare. A large percentage of HRMO isolates were extended spectrum ß-lactamase producers, indicating the rapid increase in the production of this resistance mechanism in recent years. The transmission of HRMOs in our center is controlled effectively, using well-established transmission-based precautions.
