REVIEW
M Yiasemidou, E Gkaragkani, D Glassman, C S Biyani
BACKGROUND: Traditional surgical training, largely based on the Halstedian model "see one, do one, teach one" is not as effective in the era of working time restrictions and elaborate shift-patterns. As a result, contemporary surgeons turned to educational methods outside the operating theatre such as simulation. Cadavers are high fidelity models but their use has ethical and cost implications and their availability may be limited. In this review, we explore the role of cadaveric simulation in modern surgical education...

Most assessments of physiology in medical school use multiple choice tests that may not provide information about a student's critical thinking (CT) process. There are limited performance assessments, but high-fidelity patient simulations (HFPS) may be a feasible platform. The purpose of this pilot study was to determine whether a group's CT process could be observed over a series of HFPS. An instrument [Critical Thinking Skills Rating Instrument CTSRI)] was designed with the IDEAS framework. Fifteen groups of students participated in three HFPS that consisted of a basic knowledge quiz and introduction, HFPS session, and debriefing...

BACKGROUND: High fidelity simulation creates conditions that resemble real circumstances, and can help teach procedures such as intrauterine contraception placement. Its impact on skill retention has not been studied. OBJECTIVE: To evaluate novice learners' skills, attitudes, and knowledge on placement of intrauterine contraception when trained using a high-fidelity commercially available simulator compared with a low-fidelity simulator. STUDY DESIGN: We recruited senior nurse practitioner students and interns in obstetrics and gynecology and family medicine inexperienced with intrauterine contraception placement...

PURPOSE: This work aims to generate cine CT images (i.e., 4D images with high temporal resolution) based on a novel principal component reconstruction (PCR) technique with motion learning from 2D fluoroscopic training images. METHODS: In the proposed PCR method, the matrix factorization is utilized as an explicit low-rank regularization of 4D images that are represented as a product of spatial principal components and temporal motion coefficients. The key hypothesis of PCR is that temporal coefficients from 4D images can be reasonably approximated by temporal coefficients learned from 2D fluoroscopic training projections...

Little is known about the acquisition of intubation skills among novice physicians during their one-year clinical training. Our primary objective was to determine the changes in the intubation skills of novice physicians between prior to the clinical training and after completion of the clinical training. We used data of a prospective longitudinal multicenter data registry developed to investigate factors associated with the improvement of intubation skills among novice physicians. The study participants included 90 postgraduate year 1 physicians in 2015-2016...

BACKGROUND: Isolation and long duration spaceflight are associated with musculoskeletal deconditioning. Mars500 was a unique, high-fidelity analogue of the psychological challenges of a 520-day manned mission to Mars. We aimed to explore the effect of musculoskeletal deconditioning on three outcome measures: (1) if lower limb muscle strength was reduced during the 520-day isolation; (2) if type I or II muscle fibres were differentially affected; and (3) whether any 70-day exercise interventions prevented any isolation-induced loss of strength...

Termination of protein synthesis on the ribosome requires that mRNA stop codons are recognized with high fidelity. This is achieved by specific release factor proteins that are very different in bacteria and eukaryotes. Hence, while there are two release factors with overlapping specificity in bacteria, the single omnipotent eRF1 release factor in eukaryotes is able to read all three stop codons. This is particularly remarkable as it is able to select three out of four combinations of purine bases in the last two codon positions...

BACKGROUND: Ultrasound guided regional anesthesia is widely taught using task trainer models. Commercially available models are often used; however, they can be cost prohibitive. Therefore, alternative "homemade" models with similar fidelity are often used. We hypothesize that professional task trainers will be preferred over homemade models. The purpose of this study is to determine realism, durability and cleanliness of three different task trainers for ultrasound guided nerve blocks...

OBJECTIVE: During endovascular aneurysm repair (EVAR), vessel deformations occur due to the insertion of tools and deployment of stent grafts in the arteries. We present a method for the characterization of vessel deformations during EVAR, and its application on patient datasets for a preliminary retrospective analysis that may be used to improve fidelity of endovascular simulators. DESIGN: The method provides the extraction of vessel profiles from intraoperative fluoroscopic images and the calculation of a tortuosity index in the 2D fluoroscopy view (τ2D) used to quantify the vessel deformations (δ%) during EVAR caused by the stiff guidewire insertion (δ%Stiff) and the stent graft deployment (δ%Graft), when compared with the undeformed vessel configuration (no device inserted)...

Background: Effective communication within teams is crucial, especially in crisis situations. Hierarchy gradients between team members can contribute to communication failures and are influenced by many factors. The effect of gender on team performance has not been well studied. The objective of this study was to examine the effect of the physician's gender on respiratory therapists' ability to effectively challenge clearly incorrect clinical decisions during a life-threatening crisis...

Background: Assessment of competence in basic critical care echocardiography is complex. Competence relies on not only imaging accuracy but also interpretation and appropriate management decisions. The experience to achieve these skills, real-time, is likely more than required for imaging accuracy alone. We aimed to assess the feasibility of using simulation to assess number of studies required to attain competence in basic critical care echocardiography. Methods: This is a prospective pilot study recruiting trainees at various degrees of experience in basic critical care echocardiography using experts as reference standard...

BACKGROUND: Despite being linked to improving patient outcomes and limiting costs, the use of vaginal hysterectomy is on the wane. Although a combination of reasons might explain this trend, one cause is a lack of practical training. An appropriate teaching model must therefore be devised. Currently, only low-fidelity simulators exist. Ewes provide an appropriate model for pelvic anatomy and are well-suited for testing vaginal mesh properties. This article sets out a vaginal hysterectomy procedure for use as an education and training model...

The intrinsic editing capacities of aminoacyl-tRNA synthetases ensure a high-fidelity translation of the amino acids that possess effective non-cognate aminoacylation surrogates. The dominant error-correction pathway comprises deacylation of misaminoacylated tRNA within the aminoacyl-tRNA synthetase editing site. To assess the origin of specificity of Escherichia coli leucyl-tRNA synthetase (LeuRS) against the cognate aminoacylation product in editing, we followed binding and catalysis independently using cognate leucyl- and non-cognate norvalyl-tRNA(Leu) and their non-hydrolyzable analogues...

BACKGROUND: With the help of contemporary computer technology it is possible to create a virtual surgical environment (VSE) for training. This article describes a patient-specific virtual rhinologic surgical simulation platform that supports rehearsal of endoscopic skull-base surgery. We also share our early experience with select cases. METHODS: A rhinologic VSE was developed, featuring a highly efficient direct 3-dimensional (3D) volume renderer with simultaneous stereoscopic feedback during surgical manipulation of the virtual anatomy, as well as high-fidelity haptic feedback...

In a randomized controlled trial of arthroscopic training tools, the low-cost/low-fidelity Cigar Box Arthroscopy Trainer demonstrated equivalent efficacy to the validated, and more expensive, Anatomic Knee Arthroscopy Trainer (AKAT) in the training of novice arthroscopists using a validated scoring system, the Basic Arthroscopic Knee Skill Scoring System. As simulation training and formal surgical skills training is now mandatory, residency and fellowship programs are required to incorporate training modules and equipment to maximize learning while minimizing potential for patient harm...

We report on the first experimental realization of the controlled-not (cnot) quantum gate and entanglement for two individual atoms of different isotopes and demonstrate a negligible cross talk between two atom qubits. The experiment is based on a strong Rydberg blockade for ^{87}Rb and ^{85}Rb atoms confined in two single-atom optical traps separated by 3.8  μm. The raw fidelities of the cnot gate and entanglement are 0.73±0.01 and 0.59±0.03, respectively, without any corrections for atom loss or trace loss...

OBJECTIVE: Working with the families and networks of patients with mental illness has significant benefits. There are, however, numerous barriers to this way of working, meaning that it is not universally privileged in mental healthcare services. This study evaluated the impact of an interprofessional simulation (IPS) course on working with families and networks on participants' confidence, attitudes, and perceived future clinical practice. METHODS: A one-day IPS course pairing high-fidelity scenarios with reflective debriefs was developed...
