PURPOSE: Rural health care providers (HCPs) care for millions of Americans despite challenges. Pediatric Advanced Life Support (PALS) provides rural HCPs training in assessment and interventions for critically ill/injured pediatric patients (American Heart Association, 2015). The purpose of this study was to determine the effects of integration of high fidelity simulators into PALS courses in a rural setting. DESIGN AND METHODS: Participants were randomized by course to control or experimental PALS conditions where the control group received PALS with low fidelity static manikins (LFM) and the experimental group received PALS with high-fidelity simulators (HFS)...

The gold nanosensors based on Au-S bond have been widely applied to biochemical detections. However, the signal distortion caused by biothiols has been seldom mentioned and urgently needed to be solved. Herein, we designed a novel but easily assembled gold nanoprobe by coupling selenol-modified peptide with FITC onto the gold nanoparti-cle's surface via Au-Se bond for florescence imaging of a tumor marker matrix metalloproteinases 2 (MMP-2). The Au-Se probes display a higher signal-noise ratio (SNR, 10.1) and a lower detection limit (LOD, 1...

Human factors are the most relevant issues contributing to adverse events in obstetrics. Specific training of Crisis Resource Management (CRM) skills (i.e., problem solving and team management, resource allocation, awareness of environment, and dynamic decision-making) is now widespread and is often based on High Fidelity Simulation. In order to be used as a guideline in simulated scenarios, CRM skills need to be mapped to specific and observable behavioral markers. For this purpose, we developed a set of observable behaviors related to the main elements of CRM in the delivery room...

It is imperative to incorporate education on interprofessional competencies into the curriculum of healthcare provider students in order to meet the individual program accreditation standards. However, what is missing is a theoretical foundation for the education. The purpose of this paper was to examine if the qualitative data from a mixed-methods study using low-fidelity simulation of a case study that demonstrated changes in interprofessional attitudes and behaviors in healthcare provider students aligned with Kolb's Experiential Learning Theory (ELT)...

Recent developments in highly accelerated fMRI data acquisition have employed low-rank and/or sparsity constraints for image reconstruction, as an alternative to conventional, time-independent parallel imaging. When under-sampling factors are high or the signals of interest are low-variance, however, functional data recovery can be poor or incomplete. We introduce a method for improving reconstruction fidelity using external constraints, like an experimental design matrix, to partially orient the estimated fMRI temporal subspace...

Generalized high-fidelity closed-form formulae have been developed to predict the shear modulus of hexagonal graphene-like monolayer nanostructures and nano-heterostructures based on a physically insightful analytical approach. Hexagonal nano-structural forms (top view) are common for nanomaterials with monoplanar (such as graphene and hBN) and multiplanar (such as stanene and MoS2 ) configurations. However, a single-layer nanomaterial may not possess a particular property adequately, or multiple desired properties simultaneously...

OBJECTIVE: Resuscitative Thoracotomy or Emergency Department Thoracotomy (EDT) is a time-sensitive and potentially life-saving procedure. Yet, trainee experience with this procedure is often limited in both clinical and simulation settings. We sought to develop a high-fidelity EDT simulation module and assessment tool to facilitate trainee education. DESIGN: Using the Kern model for curricular development, a group of expert trauma surgeons identified EDT as a high-stakes, low-frequency procedure...

Surgical traineeship has traditionally been based on a master apprentice model where learning takes place in the operating theatre. This approach has changed over the past few years with greater emphasis on surgical training taking place within the surgical skills laboratory. We developed a high fidelity simulator, the Image-guided Robotic Assisted Surgical simulator (IRAS) with an incorporated robotic guidance feature. The robot system is developed to mimic the process of an experienced surgeon physically holding a trainee's hands to demonstrate maneuvering of the laparoscopic instruments...

Spirometry is a widely used pulmonary function test to detect the airflow limitations associated with various obstructive lung diseases, such as asthma, chronic obstructive pulmonary disease (COPD), and even obesity-related complications. These conditions arise due to the change in the airway resistance, alveolar compliance, and inductance values. Currently, zero-dimensional (0D) compartmental models are commonly used for calibrating these resistance, compliance, and inductance values, i.e., solving the inverse spirometry problem...

INTRODUCTION: Critically ill children who require transfer to tertiary care centers often require transport by specialized transport teams (TT). These interfacility transports require a medical control physician (MCP). Traditionally this role is assigned to fellows who are taught "on-the-job", but achieving competency in communication for those trained this way may not be optimal. We sought to close this curriculum gap by developing a MCP training program immersing emergency medicine (EM) and critical care (CC) fellows together with TT members to manage a simulated patient...
