SimKinet: A free educational tool based on an electrical analogy to solve chemical kinetic equations.

ABSTRACT: In this article we introduce the software SimKinet, a free tool specifically designed to solve systems of differential equations without any programming skill. The underlying method is the so-called Network Simulation Method, which designs and solves an electrical network equivalent to the mathematical problem. SimKinet is versatile, fast, presenting a real user-friendly interface, and can be employed for both educational and researching purposes. It is particularly useful in the first courses of different scientific degrees, mainly Chemistry and Physics, especially when facing non-analytic or complex-dynamics problems. Moreover, SimKinet would help students to understand fundamental concepts, being an opportunity to improve instruction in Chemistry, Mathematics, Physics and other Sciences courses, with no need of advanced knowledge in differential equations. The potency of SimKinet is demonstrated via two applications in chemical kinetics: the photochemical destruction of stratospheric ozone and the chaotic dynamics of the peroxidase-oxidase reaction.

Project description:ObjectivesProcedural competency is an essential prerequisite for the independent practice of emergency medicine. Multiple studies demonstrate that simulation-based procedural training (SBPT) is an effective method for acquiring and maintaining procedural competency and preferred over traditional paradigms ("see one, do one, teach one"). Although newer paradigms informing SBPT have emerged, educators often face circumstances that challenge and undermine their implementation. The goal of this paper is to identify and report on best practices and theory-supported solutions to some of these challenges as derived using a process of expert consensus building and reviews of the existing literature on SBPT.MethodsThe Society for Academic Emergency Medicine (SAEM) Simulation Academy SBPT Workgroup convened approximately 8 months prior to the 2019 SAEM Annual Meeting to perform a review of the literature and participate in a consensus-building process to identify solutions (in the form of best practices and educational theory) to these challenges faced by educators engaging in SBPT.Results and analysisThirteen distinct educational challenges to SBPT emerged from the expert group's primary literature reviews and consensus-building processes. Three domains emerged upon further analysis of the 13 challenges: learner, educator, and curriculum. Six challenges within the "learner" domain were selected for comprehensive discussion in this paper, as they were deemed representative of the most common and most significant threats to ideal SBPT. Each of the six challenges aligns with one of the following themes: 1) maximizing active learning, 2) maintaining learner engagement, 3) embracing learner diversity, 4) optimizing cognitive load, 5) promoting mindfulness and reflection, and 6) emphasizing deliberate practice for mastery learning. Over 20 "special treatments" for mitigating the impact of the 13 challenges were derived from the secondary literature search and consensus-building process prior to and during the preconference workshop; 11 of these that best address the six learner-centered challenges are explored, including implications for educators involved in SBPT.Conclusions/implications for educatorsWe propose multiple consensus-generated solutions (in the form of best practices and applied educational theory) that we believe are suitable and well aligned to overcome commonly encountered learner-centered challenges and threats to optimal SBPT.

Project description:BackgroundInternational travel has been recognized as a risk factor contributing to the spread of antimicrobial resistance (AMR). However, tools focused on AMR in the context of international travel and designed to guide decision-making are limited. We aimed at developing an evidence-based educational tool targeting both healthcare professionals (HCPs) and international travellers to help prevent the spread of AMR.MethodsA literature review on 12 antimicrobial-resistant bacteria (ARB) listed as critical and high tiers in the WHO Pathogen Priority List covering four key areas was carried out: AMR surveillance data; epidemiological studies reporting ARB prevalence data on carriage in returning travellers; guidance documents reporting indications on screening for ARB in returning travellers and recommendations for ARB prevention for the public. The evidence, catalogued at country-level, provided the content for a series of visualizations that allow assessment of the risk of AMR acquisition through travel.ResultsUp to January 2021, the database includes data on: (i) AMR surveillance for 2.018.241 isolates from 86 countries; (ii) ARB prevalence of carriage from 11.679 international travellers and (iii) 15 guidance documents published by major public health agencies. The evidence allowed the development of a consultation scheme for the evaluation of risk factors, prevalence of carriage, proportion and recommendations for screening of AMR. For the public, pre-travel practical measures to minimize the risk of transmission were framed.ConclusionsThis easy-to-use, annually updated, freely accessible AMR travel tool (https://epi-net.eu/travel-tool/overview/), is the first of its kind to be developed. For HCPs, it can provide a valuable resource for teaching and a repository that facilitates a stepwise assessment of the risk of AMR spread and strengthen implementation of optimized infection control measures. Similarly, for travellers, the tool has the potential to raise awareness of AMR and outlines preventive measures that reduce the risk of AMR acquisition and spread.
