PURPOSE: The review of a radiation therapy plan by a physicist prior to treatment is a standard tool for ensuring the quality of treatments. However, little is known about how well this task is performed in practice. The goal of this study is to present a novel method to measure the effectiveness of physics plan review by introducing simulated errors into computerized "mock" treatment charts and measuring the performance of plan review by physicists. METHODS: We generated six simulated treatment charts containing multiple errors...

Based on the quantitative structure-activity relationship (QSAR), some novel p-aminobenzoic acid derivatives as promising cholinesterase enzyme inhibitors were designed, synthesized, characterized and evaluated to enhance learning and memory. The in vitro enzyme kinetic study of the synthesized compounds revealed the type of inhibition on the respective acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes. The in vivo studies of the synthesized compounds exhibited significant reversal of cognitive deficits in the animal models of amnesia as compared to standard drug donepezil...

BACKGROUND: Simulation is progressively being integrated into surgical training, yet its utility in plastic surgery has not been well described. We present a prospective, randomized, blinded trial comparing digital simulation to a surgical textbook for conceptualization of cleft-lip repair. METHODS: Thirty-five medical students were randomized to learning cleft repair using a simulator or textbook. Participants outlined markings for a standard cleft-lip repair before (pre-intervention) and after (post-intervention) 20 minutes of studying their respective resource...

Introduction: In hernia surgery, too, the influence of the surgeon on the outcome can be demonstrated. Therefore the role of the learning curve, supervised procedures by surgeons in training, simulation-based training courses and surgeon volume on patient outcome must be identified. Materials and Methods: A systematic search of the available literature was carried out in June 2018 using Medline, PubMed, and the Cochrane Library. For the present analysis 81 publications were identified as relevant. Results: Well-structured simulation-based training courses was found to be associated with a reduced perioperative complication rate for patients operated on by trainees...

Background Full disclosure of patient safety events (PSE) is desired by patients and their families, is required by the Joint Commission and many state laws, and is vital to improving patient outcomes. A key barrier to consistent disclosure of patient safety events is a self-reported lack of proper training. Physicians must be trained to recognize when a PSE has occurred and effectively carry out disclosure, all while caring for a patient who is actively experiencing the consequences of an unintended outcome...

This paper presents a novel approach for indoor acoustic source localization using microphone arrays, based on a Convolutional Neural Network (CNN). In the proposed solution, the CNN is designed to directly estimate the three-dimensional position of a single acoustic source using the raw audio signal as the input information and avoiding the use of hand-crafted audio features. Given the limited amount of available localization data, we propose, in this paper, a training strategy based on two steps. We first train our network using semi-synthetic data generated from close talk speech recordings...

We sought to understand the mechanisms underlying cognitive deficits that are reported to affect non-native subjects following their prolonged stay and/or work at high altitude (HA). We found that mice exposed to a simulated environment of 5000 m exhibit deficits in hippocampal learning and memory accompanied by abnormalities in brain MR imaging. Exposure (1-8 months) to HA led to an increase in brain ventricular volume, a reduction in relative cerebral blood flow and changes in diffusion tensor imaging (DTI) derived parameters within the hippocampus and corpus callosum...

OBJECTIVE: The effects of inertial (vestibular and somatosensory) information on driver steering during curve navigation were investigated, using an electric four-wheel mobility vehicle outfitted with a steering wheel and a portable virtual reality system. BACKGROUND: When driving, multiple sources of perceptual information are available. Researchers have focused on visual information, which plays a critical role in steering control. However, it is not yet well established how inertial information might contribute...

Magnetic resonance imaging (MRI) is an extremely useful tool for the detection and characterization of numerous pathologic processes. Although patients can benefit from the use of MRI, claustrophobia is a major issue in some cases. This fear alone can lead to cancellation of the scanning procedure in some cases and the need for conscious sedation in others. Patient anxiety during the scan can also lead to increased motion-related artifacts on the images with associated degradation of the diagnostic quality of the study...

Learning in physical neural systems must rely on learning rules that are local in both space and time. Optimal learning in deep neural architectures requires that non-local information be available to the deep synapses. Thus, in general, optimal learning in physical neural systems requires the presence of a deep learning channel to communicate non-local information to deep synapses, in a direction opposite to the forward propagation of the activities. Theoretical arguments suggest that for circular autoencoders, an important class of neural architectures where the output layer is identical to the input layer, alternative algorithms may exist that enable local learning without the need for additional learning channels, by using the forward activation channel as the deep learning channel...

INTRODUCTION: Currently, simulation training is not part of the clinical clerkship rotation in obstetrics and gynaecology (OB/GYN) at the University of Toronto. Instead, students are taught formally through lectures and informally on the ward or in the operating room. This study aimed to incorporate simulation using a high fidelity postpartum hemorrhage (PPH) workshop into the teaching curriculum, with the goal of improving both medical knowledge of PPH and nontechnical skills (NTS). METHOD: A novel teaching session was introduced for the third-year clerks on their OB/GYN rotation...

BACKGROUND: Traditional interprofessional educational (IPE) exercises are those where learning exists "about, from, and with" trainees in two or more professions in order to prepare health sciences professionals to work on interprofessional teams. One emerging difficulty with IPE is the paucity of health profession students at single institutions, and the geographic and financial constraints of multi-institutional collaboration. INTERPROFESSIONAL EDUCATION ACTIVITY: To circumvent these barriers, we developed a multi-institution telehealth team-based learning (TBL) event between medical and pharmacy students on the topic of pharmacogenomics (PGx)...

BACKGROUND: DNA inside eukaryotic cells wraps around histones to form the 11nm chromatin fiber that can further fold into higher-order DNA loops, which may depend on the binding of architectural factors. Predicting how the DNA will fold given a distribution of bound factors, here viewed as a type of sequence, is currently an unsolved problem and several heterogeneous polymer models have shown that many features of the measured structure can be reproduced from simulations. However a model that determines the optimal connection between sequence and structure and that can rapidly assess the effects of varying either one is still lacking...

Foraging mammalian predators face a myriad of odors from potential prey. To be efficient they must focus on rewarding odor while ignoring consistently unrewarding ones. This may be exploited as a non-lethal conservation tool if predators can be deceived into ignoring odors of vulnerable secondary prey. To explore critical design components and assess the potential gains to prey survival of this technique, we created an individual-based model that simulated the hunting behavior of three introduced mammalian predators on one of their secondary prey (a migratory shorebird) in the South Island of New Zealand...
