INTRODUCTION: Traditional simulation debriefing is both time‐ and resource‐intensive. Shifting the degree of primary learning responsibility from the faculty to the learner through self‐guided learning has received greater attention as a means of reducing this resource intensity. The aim of the study was to determine if video‐assisted self‐debriefing, as a form of self‐guided learning, would have equivalent learning outcomes compared to standard debriefing. METHODS: This randomized cohort study consisting of 49 PGY‐1 to ‐3 emergency medicine residents compared performance after video self‐assessment utilizing an observer checklist versus standard debriefing for simulated emergency department procedural sedation (EDPS). The primary outcome measure was performance on the second EDPS scenario. RESULTS: Independent‐samples t‐test found that both control (standard debrief) and intervention (video self‐assessment) groups demonstrated significantly increased scores on Scenario 2 (standard—t(40) = 2.20, p

Radiation accelerates ageing, producing telomere shortening, metabolic ageing, cell apoptosis, immunological decline, mitochondrial damage, free radical damage and oxidative stress. Salts of iodine, strontium and caesium may reverse ageing induced by nuclear radiation. The American Thyroid Association (ATA) has established that potassium iodide (KI) needs to be accessible to those within 50 miles of nuclear reactors. Despite ATA recommendations, if you distribute KI at the time of explosion, it may not be effective; thus, it is a preventive measure, not a tertiary treatment. KI treatment is most successful when used prior to radioactive iodine exposure. Weekly supplementation of KI reduces hypothyroidism and thyroid nodules; strontium carbonate (SrCO3) reduces osteopenia and inadequate bone development; and caesium chloride (CsCl) reduces brain cell apoptosis and anxiety. Low doses of radiation may result in hormesis and improved health. A radiation cleanup plan with further investigation could be implemented as a preventive measure.
