INTRODUCTION: High-fidelity simulation is frequently utilized in medical education. Its use in the neurosciences is limited by the inherent limitations of the manikin to simulate neurological changes. We report here the use of a hybrid simulation - a combination of lecture and high-fidelity manikin - in the education of neurosciences nurses, involved in care of neurocritical care patients. METHODS: Neurosciences nurses from at the University of Missouri, Columbia, MO, USA, which is an academic, tertiary-care medical center participated in the simulation during Spring of 2016...

INTRODUCTION: Although traditional virtual patient simulations are designed to teach and assess clinical reasoning skills, few employ conversational dialogue with the patients. The virtual standardized patients (VSPs) described herein represent standardized patients that students interview using natural language. Students take histories and develop differential diagnoses of the VSPs as much as they would with standardized or actual patients. The student-VSP interactions are recorded, creating a comprehensive record of questions and the order in which they were asked, which can be analyzed to assess information-gathering skills...

INTRODUCTION: Technical skill acquisition for rare procedures can be challenging given the few real-life training opportunities. In situ simulation (ISS), a training technique that takes place in the actual workplace, is a promising method to promote environmental fidelity for rare procedures. This study evaluated a simulation-based technical skill curriculum for cricothyroidotomy using deliberate practice, followed by an ISS evaluation session. METHODS: Twenty emergency medicine residents participated in a two-part curriculum to improve cricothryoidotomy performance...

Medical simulation is a rapidly expanding area within medical education due to advances in technology, significant reduction in training hours and increased procedural complexity. Simulation training aims to enhance patient safety through improved technical competency and eliminating human factors in a risk free environment. It is particularly applicable to a practical, procedure-orientated specialties. Simulation can be useful for novice trainees, experienced clinicians (e.g. for revalidation) and team building...

Neurons that respond favorably to a particular sound level have been observed throughout the central auditory system, becoming steadily more common at higher processing areas. One theory about the role of these level-tuned or nonmonotonic neurons is the level-invariant encoding of sounds. To investigate this theory, we simulated various subpopulations of neurons by drawing from real primary auditory cortex (A1) neuron responses and surveyed their performance in forming different sound level representations...

Flight initiation is fundamental for survival, escape from predators and lifting payload from one place to another in biological fliers and can be broadly classified into jumping and non-jumping takeoffs. During jumping takeoffs, the legs generate most of the initial impulse. Whereas the wings generate most of the forces in non-jumping takeoffs, which are usually voluntary, slow, and stable. It is of great interest to understand how these non-jumping takeoffs occur and what strategies insects use to generate large amount of forces required for this highly demanding flight initiation mode...

Knowledge of ureteric anatomy is essential for ureteric injury prevention in laparoscopic gynecologic surgery. Rates of injury increase with limited surgical experience and reduced surgical volume. Currently there are no low-fidelity or high-fidelity simulation models for teaching and practicing ureteric dissection. Our goal was to design a laparoscopic simulation model for retroperitoneal anatomy with high face validity that is low-cost and easily reproducible.

Simulation allows for learner-centered health professions training by providing a safe environment to practice and make mistakes without jeopardizing patient care. It was with this goal in mind that the McGill Medical Simulation Center was officially opened on September 14, 2006, as a partnership between McGill University, the Faculty of Medicine and its affiliated hospitals. Its mandate is to provide state-of-the-art facilities to support simulation-based medical and allied health education initiatives. Since its inception, the center, recently renamed the Steinberg Center for Simulation and Interactive Learning (SCSIL), has undergone a major expansion and logged more than 130,000 learner visits...

Current photon counting x-ray detector (PCD) technology faces limitations associated with spectral fidelity and photon starvation. One strategy for addressing these limitations is to supplement PCD data with high-resolution, low-noise data acquired with an energy-integrating detector (EID). In this work, we propose an iterative, hybrid reconstruction technique which combines the spectral properties of PCD data with the resolution and signal-to-noise characteristics of EID data. Our hybrid reconstruction technique is based on an algebraic model of data fidelity which substitutes the EID data into the data fidelity term associated with the PCD reconstruction, resulting in a joint reconstruction problem...

Surface flow phenomena, such as rain water flowing down a tree trunk and progressive water front in a shower room, are common in real life. However, compared with the 3D spatial fluid flow, these surface flow problems have been much less studied in the graphics community. To tackle this research gap, we present an efficient, robust and high-fidelity simulation approach based on the shallow-water equations. Specifically, the standard shallow-water flow model is extended to general triangle meshes with a feature-based bottom friction model, and a series of coherent mathematical formulations are derived to represent the full range of physical effects that are important for real-world surface flow phenomena...

BACKGROUND: Anesthesia providers have long been pioneers in patient safety. Despite remarkable efforts, anesthesia errors still occur, resulting in complications, injuries, and even death. The Veterans Health Administration (VHA) National Center of Patient Safety uses root cause analysis (RCA) to examine why system-related adverse events occur and how to prevent future similar events. This study describes the types of anesthesia adverse events reported in VHA hospitals and their root causes and preventative actions...

BACKGROUND: Use of high fidelity simulation has become increasingly popular in nursing education to the extent that it is now an integral component of most nursing programs. Anecdotal evidence suggests that students have difficulty engaging with simulation manikins due to their unrealistic appearance. Introduction of the manikin as a 'real patient' with the use of an audio-visual narrative may engage students in the simulated learning experience and impact on their learning. A paucity of literature currently exists on the use of audio-visual narratives to enhance simulated learning experiences...

This paper discusses a novel model combustion experiment that was built for studying the structure and dynamics of a reacting jet in an unsteady crossflow. A natural-gas-fired dump combustor is used to generate and sustain an acoustically oscillating vitiated flow that serves as the crossflow for transverse jet injection. Unlike most other techniques that are limited in operating pressure or acoustic amplitude, this method of generating an unsteady flow field is demonstrated at a pressure of 10 atm with peak-to-peak oscillation amplitudes approaching 20% of the mean pressure...

OBJECTIVE: To assess the sensitivity of gaze-based metrics in detecting cognitive demands imposed by surgical procedures. We analyzed urologists' gaze entropy and velocity while performing two standardized high-fidelity simulated stone procedures with different levels of complexity. METHODS: Using a wearable eye-tracker device (mounted onto an eyeglass frame), we measured gaze entropy and velocity in fifteen urologists, members of the Andalusian healthcare system, while they performed an extraction of a stone in the bladder (low complexity) and an extraction of a stone in the lumbar ureter (high complexity)...

Background Childbirth is a physiological process. However a normal delivery may suddenly turn into a life-threatening emergency. In this case, maternal and infant health depends largely on appropriate and timely interventions, and effective teamwork of all professionals. In order to meet the complex requirements, different concepts for interdisciplinary simulation training in obstetric emergencies have been developed and evaluated mainly in Scandinavian and English-speaking countries. In this context, both high-fidelity and low-fidelity trainings have been found to be effective...
