Perceptions of using infographics for scientific communication on social media for COVID-19 topics: a survey study.

Navigating for accurate information, especially health- and science-related content, on social media has been challenging during the COVID-19 pandemic. Although infographics are a popular medium for simplifying text-based information into visual components, their usefulness during a global health crisis has not been explored. The study aims to explore the perceptions of infographics in conveying scientific information related to COVID-19 on social media. Following a social media campaign that published COVID-19 related infographics from May to August 2020, a cross-sectional survey was administered to social media users, primarily students from Western University. Several questions asked respondents to make comparisons with written articles when reporting their perceptions of infographics. Seventy-three percent of students from 361 responses belonged to health-related academic backgrounds. Seventy-two percent felt more likely to share infographics than written articles on social media due to the visual appeal. Nearly 90% felt it was easier to navigate through complicated science and that more scientists should use infographics on social media. Educational background did not influence the perceived usefulness of infographics in understanding scientific information. Infographics are perceived favourably in conveying scientific information about COVID-19 on social media. Findings from this study can inform communication strategies during a pandemic and, more broadly, global crises.

The Need for Health Policy Training for Surgeons.

BACKGROUND: Improvements in surgery at a systems level can be mediated by effective health policy. METHODS: We reviewed three contemporary challenges in surgical care to understand the potential role of health policy. RESULTS: The pandemic-related backlog, and international economic and logistical challenges to surgical care may be improved through policy change and advocacy by surgeons. CONCLUSIONS: A surgeon-policy expert training pathway and professional role will ensure surgeons contribute meaningfully to health policy development.

Association between genetic mutations and risk of venous thromboembolism in patients with solid tumor malignancies: A systematic review and meta-analysis.

BACKGROUND: Venous thromboembolism (VTE) is a frequent complication in cancer patients and is associated with significant morbidity, mortality, and burden on the health care system [1]. Previous studies have suggested an association between genetic mutations in solid tumors and VTE risk. METHODS: MEDLINE and EMBASE databases were searched from inception to February 2021. We aimed to include studies presenting data on VTE and genetic mutations with >5% frequency in patients with melanoma, small cell lung cancer (SCLC), non-small cell lung cancer (NSCLC), and colon, gastric and ovarian cancers. Meta-analyses of proportions and size effects were conducted if possible. RESULTS: Of 682 eligible articles, we included 33 articles, of which 26 papers reporting on a total of 13,844 patients were included in the meta-analysis. The estimated proportions of VTE in lung cancer patients with EGFR, KRAS, and ALK mutations were 7.3, 18.2, and 30.6%, respectively, whereas for colon cancer with KRAS mutations was 13%. In NSCLC patients with EGFR, KRAS and ALK mutations the relative risk (RR) of VTE was 0.98 (0.81-1.18, P = 0.818), 1.24 (0.78-1.97 P = 0.358) and 1.70 (1.46-1.97, P < 0.001), respectively using a fixed-effects model. In patients with colon cancer and KRAS mutation, no significant increase in the VTE risk was observed according to the random-effects model, RR 1.31 (0.79-2.19, P = 0.285). CONCLUSION: In patients with NSCLC, the presence of ALK mutations was associated with a high proportion and RR of developing VTE. There was no significant increase in the risk of VTE in patients with colon cancer and KRAS mutations.
