Sensors, Vol. 19, Pages 4270: Toward Dynamically Adaptive Simulation: Multimodal Classification of User Expertise Using Wearable Devices Sensors doi: 10.3390/s19194270 Authors: Kyle Ross Pritam Sarkar Dirk Rodenburg Aaron Ruberto Paul Hungler Adam Szulewski Daniel Howes Ali Etemad Simulation-based training has been proven to be a highly effective pedagogical strategy. However, misalignment between the participant’s level of expertise and the difficulty of the simulation has been shown to have significant negative impact on learning outcomes. To ensure that learning outcomes are achieved, we propose a novel framework for adaptive simulation with the goal of identifying the level of expertise of the learner, and dynamically modulating the simulation complexity to match the learner’s capability. To facilitate the development of this framework, we investigate the classification of expertise using biological signals monitored through wearable sensors. Trauma simulations were developed in which electrocardiogram (ECG) and galvanic skin response (GSR) signals of both novice and expert trauma responders were collected. These signals were then utilized to classify the responders’ expertise, successive to feature extraction and selection, using a number of machine learning methods. The results show the feasibility of utilizing these bio-signals for multimodal expertise classification to be used in adaptive simulation applications.

A 48-year-old kidney transplant recipient was admitted to our hospital with nausea, polyuria, diffuse paresthesia, and muscle weakness of all extremities. His past medical history was remarkable for renal transplantation with impaired graft function (baseline glomerular filtration rate approximately 20 ml/min per 1.73 m2) and parathyroidectomy due to an uncontrolled hyperparathyroidism. An electrocardiogram showed pronounced concave ST-segment elevations in leads II, III, and aVF suspicious of an acute ST elevation myocardial infarction as well as ascending elevations deriving from a deep S wave especially in leads V1 &nda...

Authors: Kaneko K, Chikamoto A, Hsu JC, Tochinai R, Sekizawa SI, Yamamoto M, Kuwahara M Abstract Environmental enrichment (EE) can reduce anxiety and stress in experimental animals, while little is known about the influence on autonomic nervous activity especially in disease animal models. Diabetes mellitus (DM) is associated with cardiovascular autonomic dysfunction, which can be characterized by a higher resting heart rate and a lower heart rate variability (HRV). We hypothesized that EE can enhance parasympathetic nervous activity while reducing disease progression in type 2 diabetic mice. A telemetry transmitte...

ConclusionAMI as a result of penetrating trauma is rare, but can occur secondary to an acute thrombus, even in the absence of a direct cardiac injury. MI should be a consideration in patients with penetrating trauma to the chest, regardless of the intensity of the trauma. At minimum, a 12-lead electrocardiogram (ECG) and a baseline troponin should be obtained at initial evaluation and post-operatively, if surgically managed. If ECG demonstrates findings concerning for MI, it should be followed with an echocardiogram and/or cardiac angiogram to further help guide management, with an early cardiology consultation.

In conclusion, about one-third of the patients with AF did not regularly see a doctor in a medical institution and most of them had a CHADS2 score of more than one point in a Japanese rural area. Educating the public about the risks of AF is required. PMID: 31735770 [PubMed - as supplied by publisher]

Seizure is a common presenting complaint in the pediatric emergency department (ED). Initial diagnostic investigation beyond a thorough history and physical examination typically focuses on searching for reversible causes of a seizure, predisposing factors which may have precipitated a seizure, and diagnoses which could mimic seizures. Initial evaluation is variable based on the clinical scenario and available resourced in the ED, but is generally minimal, sometimes involving neuroimaging or biochemical evaluation [1,2].

ConclusionsAlthough the previous results in 2000 suggested an association between cumulative exposure to cobalt and echocardiographic findings, the results of this new cross-sectional study with a tissue Doppler 6 years later did not confirm the association in the present cohort. If cobalt exposure affects heart muscle functions at this exposure level, the effects are smaller than those caused by physiological changes due to ageing, medication, and traditional cardiovascular risk factors, such as elevated blood pressure.

This article explains the pharmacological mechanism of action of drug-induced proarrhythmia associated with compounds that prolong the repolarization period, illustrates how this liability is conveyed in a drug's prescribing information (label), details the clinical characteristics of patients most susceptible to this type of proarrhythmia, and describes interventions that can be made if TdP occurs. Three clinical vignettes are provided at the end of the article to highlight the relevance of the preceding discussions. PMID: 31743455 [PubMed - as supplied by publisher]
