BACKGROUND: Clinical-simulated training has shown benefit in the education of medical students. However, the role of clinical simulation for surgical basic skill training such as suturing techniques remains unclear. MATERIALS AND METHODS: Forty-two medical students were asked to perform specific suturing tasks at three stations with the different settings within four minutes (Station 1: Synthetic suture pad fixed on the bench, Station 2: Synthetic suture pad fixed on the standardized patient, Station 3: Pig skin fixed on the standardized patient); the OSATS (Objective Structured Assessment of Technical Skill) tool was used to evaluate the performance of students...

An improvement in quality of medical external post-mortem examinations among others can be achieved by more intensive training of medical students. Modern learning and teaching methods such as e-learning modules and SkillsLab stations should be used for this. The introduction of corresponding methods of assessment such as the OSCE procedure is necessary to test the success of learning. In Halle (Germany), two OSCE stations on the subject of external post-mortem examinations were introduced in 2016. The 'practical external post-mortem examination' station test skills and abilities students have learned during practical external post-mortem examination in small group classes on a simulation doll...

In some randomized (drug versus placebo) clinical trials, the estimand of interest is the between-treatment difference in population means of a clinical endpoint that is free from the confounding effects of "rescue" medication (e.g., HbA1c change from baseline at 24 weeks that would be observed without rescue medication regardless of whether or when the assigned treatment was discontinued). In such settings, a missing data problem arises if some patients prematurely discontinue from the trial or initiate rescue medication while in the trial, the latter necessitating the discarding of post-rescue data...

Cochlear implants (CIs) are surgically implanted medical devices used to treat individuals with severe-to-profound sensorineural hearing loss. Although these devices have been remarkably successful at restoring audibility, many patients experience poor outcomes. Our group has developed the first image-guided CI programming technique where the electrode positions are found in CT images and used to estimate neural activation patterns, which is unique information that audiologists can use to define patient-specific processor settings...

Medical education is associated with significant costs. These costs have led to a growing interest in how to deliver high quality or high quantity education on a limited budget. This in turn has led to an interest in how best to measure quantity, quality and cost and how to track these variables over time. The ultimate aim of the interest in cost and value in medical education is to improve quality or quantity over time and to reduce costs. This may occur by a number of methods - which might include e-learning or simple simulations...

In the present study, we aimed at estimating the production of medical Ac-225 radionuclide via proton accelerator in the energy range Eproton=1000 →1MeV under certain conditions, on thorium target material instead of uranium due to the low abundant of uranium in nature. Hence, to produce the medical Ac-225, cross-section, separation energy was calculated by taking into account the proton induced reaction processes that were simulated to estimate activity and, yield of the product up to 1000MeV. Moreover, the calculated integral yields of reactions were presented...

BACKGROUND: The ability of characteristics to predict first time performance in laparoscopic tasks is not well described. Videogame experience predicts positive performance in laparoscopic experiences but its mechanism and confounding-association with aptitude remains to be elucidated. This study sought to evaluate for innate predictors of laparoscopic performance in surgically naive individuals with minimal videogame exposure. METHODS: Participants with no prior laparoscopic exposure and minimal videogaming experience were recruited consecutively from preclinical years at a medical university...

BACKGROUND: Simulation-based medical training (SBMT) is a powerful tool for continuing medical education. In contrast to the Anglo-Saxon medical education community, up until recently, SBMT was scarce in continental Europe's pediatric health care education: In 2009, only 3 Swiss pediatric health care institutions used SBMT. The Swiss catalogue of objectives in Pediatrics does not acknowledge SBMT. The aim of this survey is to describe and analyze the current state of SBMT in Swiss pediatric hospitals and health care departments...

Soft tissue neck injuries, also referred to as whiplash injuries, which can lead to long term suffering accounts for more than 60% of the cost of all injuries leading to permanent medical impairment for the insurance companies, with respect to injuries sustained in vehicle crashes. These injuries are sustained in all impact directions, however they are most common in rear impacts. Injury statistics have since the mid-1960s consistently shown that females are subject to a higher risk of sustaining this type of injury than males, on average twice the risk of injury...

Given the potential risk of X-ray radiation to the patient, low-dose CT has attracted a considerable interest in the medical imaging field. Currently, the main stream low-dose CT methods include vendor-specific sinogram domain filtration and iterative reconstruction algorithms, but they need to access raw data whose formats are not transparent to most users. Due to the difficulty of modeling the statistical characteristics in the image domain, the existing methods for directly processing reconstructed images cannot eliminate image noise very well while keeping structural details...

The (89)Zr, is one of the radionuclide with near-ideal properties for PET due to its suitable half-life and decay properties. The cross-section of (89)Zr via (89)Y(p,n)(89)Zr, (89)Y(d,2n)(89)Zr, (nat)Sr(α,xn)(89)Zr and (nat)Zr(p,pxn)(89)Zr, were calculated by the TALYS-1.8 code to predict the optimum range of charge particle energy. The Monte Carlo code GEANT4 was used to simulate the formation of (89)Zr in the target body. The simulated (89)Zr yield was in good agreement with published experimental results in the optimum energy range...

COmputation of Local Electron Release (COOLER), a software program designed for dosimetry assessment at the cellular/subcellular scale, with a given distribution of administered low-energy electron-emitting radionuclides in cellular compartments, which remains a critical step in risk/benefit analysis for advancements in internal radiotherapy. The software is intended to overcome the main limitations of the medical internal radiation dose (MIRD) formalism for calculations of cellular S-values (i.e., dose to a target region in the cell per decay in a given source region), namely, the use of the continuous slowing down approximation (CSDA) and the assumption of a spherical cell geometry...
