BACKGROUND: Simulation-based medical education (SBME) has traditionally been conducted as off-site simulation in simulation centres. Some hospital departments also provide off-site simulation using in-house training room(s) set up for simulation away from the clinical setting, and these activities are called in-house training. In-house training facilities can be part of hospital departments and resemble to some extent simulation centres but often have less technical equipment. In situ simulation, introduced over the past decade, mainly comprises of team-based activities and occurs in patient care units with healthcare professionals in their own working environment...

MOTIVATION: Reconstruction of ancestral sequence histories, and estimation of parameters like indel rates, are improved by using explicit evolutionary models and summing over uncertain alignments. The previous best tool for this purpose (according to simulation benchmarks) was ProtPal, but this tool was too slow for practical use. RESULTS: Historian combines an efficient reimplementation of the ProtPal algorithm with performance-improving heuristics from other alignment tools...

BACKGROUND: Mental workload is the amount of mental effort involved in performing a particular task. Crisis situations may increase mental workload, which can subsequently negatively impact operative performance and patient safety. This study aims to measure the impact of learning through debriefing and a systematic approach to crisis on trainees' mental workload in a simulated surgical crisis. METHODS: Twenty junior surgical residents participated in a high-fidelity, simulated, postoperative crisis in a surgical ward environment (pretest)...

Gregory Gilmour, James McKivigan
INTRODUCTION: Historically, testing medical students' skills using a handheld ophthalmoscope has been difficult to do objectively. Many programs train students using plastic models of the eye which are a very limited fidelity simulator of a real human eye. This makes it difficult to be sure that actual proficiency is attained given the differences between the various models and actual patients. The purpose of this article is to introduce a method of testing where a medical student must match a patient with his/her fundus photo, ensuring objective evaluation as well as developing skills on real patients which are more likely to transfer into clinical practice directly...

OBJECTIVE: The adaptive behaviour of mobile phone distracted drivers has been a topic of much discussion in the recent literature. Both simulator and naturalistic studies suggests that distracted drivers generally select lower driving speeds; however, speed adaptation is not observed among all drivers, and the mechanisms of speed selection are not well understood. The aim of this research was to apply a driver behavioural adaptation model to investigate the speed adaptation of mobile phone distracted drivers...

As a result of recent work-hours limitations and concerns for patient safety, innovations in extraclinical surgical simulation have become a desired part of residency education. Current simulation models, including cadaveric, animal, bench-top, virtual reality (VR) and robotic simulators are increasingly used in surgical training programs. Advances in telesurgery, three-dimensional (3D) printing, and the incorporation of patient-specific anatomy are paving the way for simulators to become integral components of medical training in the future...

PURPOSE: To investigate the feasibility of using structural-based principal component analysis (PCA) motion-modeling and weighted free-form deformation to estimate on-board 4D-CBCT using prior information and extremely limited angle projections for potential 4D target verification of lung radiotherapy. METHODS: A technique for lung 4D-CBCT reconstruction has been previously developed using a deformation field map (DFM)-based strategy. In the previous method, each phase of the 4D-CBCT was generated by deforming a prior CT volume...

Mimicry is one of the oldest concepts in biology, but it still presents many puzzles and continues to be widely debated. Simulation of wasps with a yellow-black abdominal pattern by other insects (commonly called "wasp mimicry") is traditionally considered a case of resemblance of unprofitable by profitable prey causing educated predators to avoid models and mimics to the advantage of both (Figure 1a). However, as wasps themselves are predators of insects, wasp mimicry can also be seen as a case of resemblance to one's own potential antagonist...

BACKGROUND AND PURPOSE: Locally compacting the mesh of a flow diverter by a dynamic push-pull technique can accelerate intracranial aneurysm healing. We asked how this deployment strategy compares with overlapping 2 flow diverters for aneurysmal flow reduction. MATERIALS AND METHODS: Using a high-fidelity virtual stent placement method, we simulated 3 flow-diverter strategies (single noncompacted, 2 overlapped, and single compacted) in 3 aneurysms (fusiform, large saccular, and medium saccular)...

OBJECTIVE: Simulation training improves individual clinician confidence, performance and self-efficacy in resuscitation and procedural training experiences. The reality of resuscitation experiences in the neonatal intensive care unit (NICU) is that they are team-accomplished events. However, limited data exist on team-based simulation training (TBST) in the NICU. We report the experience of TBST over a 4-year period. STUDY DESIGN: This is a retrospective report of 65 TBST events in a 71-bed Level IV NICU at a regional subspecialty children's hospital...

BACKGROUND: Septic shock resuscitation bundles have poor compliance worldwide partly due to a lack of knowledge and clinical skills. High-fidelity simulation-based training is a new teaching technology in our faculty which may improve the performance of medical students in the resuscitation process. However, since the efficacy of this training method in our institute is limited, we organized an extra class for this evaluation. PURPOSE: The aim was to evaluate the effect on medical students' knowledge and confidence levels after the high-fidelity medical simulation training in septic shock management...

THEORY: Although medical students are exposed to a variety of emotions, the impact of emotions on learning has received little attention so far. Shame-provoking intimate examinations are among the most memorable events for students. Their emotions, however, are rarely addressed during training, potentially leading to withdrawal and avoidance and, consequently, performance deficits. However, emotions of negative valance such as shame may be particularly valuable for learning, as they might prompt mental rehearsal...

PURPOSE: To provide a multicriteria optimization algorithm for intensity modulated radiation therapy using pencil proton beam scanning. METHODS: Intensity modulated radiation therapy using pencil proton beam scanning requires efficient optimization algorithms to overcome the uncertainties in the Bragg peaks locations. This work is focused on optimization algorithms that are based on Monte Carlo simulation of the treatment planning and use the weights and the dose volume histogram (DVH) control points to steer toward desired plans...

PURPOSE: Multi-energy computed tomography (MECT) is an emerging application in medical imaging due to its ability of material differentiation and potential for molecular imaging. In MECT, image correlations at different spatial and channels exist. It is desirable to incorporate these correlations in reconstruction to improve image quality. For this purpose, this study proposes a MECT reconstruction technique that employes spatial spectral non-local means (ssNLM) regularization. METHODS: We consider a kVp-switching scanning method in which source energy is rapidly switched during data acquisition...
