PROBLEM: Mindfulness training includes mindfulness meditation, which has been shown to improve both attention and self-awareness. Medical providers in the intensive care unit often deal with difficult situations with strong emotions, life-and-death decisions, and both interpersonal and interprofessional conflicts. The effect of mindfulness meditation training on healthcare providers during acute care tasks such as cardiopulmonary resuscitation remains unknown. Mindfulness meditation has the potential to improve provider well-being and reduce stress in individuals involved in resuscitation teams, which could then translate into better team communication and delivery of care under stress...

In myocardial infarction, muscle tissue of the heart is damaged as a result of ceased or severely impaired blood flow. Survivors have an increased risk of further complications, possibly leading to heart failure. Material properties play an important role in determining post-infarction outcome. Due to spatial variation in scarring, material properties can be expected to vary throughout the tissue of a heart after an infarction. In this study we propose a data assimilation technique that can efficiently estimate heterogeneous elastic material properties in a personalized model of cardiac mechanics...

REVIEW
Mitchell Goldenberg, Jason Y Lee
PURPOSE OF REVIEW: Competency-based medical education (CBME) is rooted in the use of iterative assessments. We must ensure that the assessments used in CBME are valid, to make acceptable and accurate decisions regarding the competency of a trainee. Until recently, much of the educational and assessment literature in urology have used a now-outdated method of determining validity, based on theory and recommendations from over 50 years ago. We describe a contemporary approach to gathering construct validity evidence for the assessment of urologic trainees, for use in both clinical and simulation environments...

Zhonghua Sun, Dongting Liu
The aim of this systematic review is to analyse current literature related to the clinical value of three-dimensional (3D) printed models in renal disease. A literature search of PubMed and Scopus databases was performed to identify studies reporting the clinical application and usefulness of 3D printed models in renal disease. Fifteen studies were found to meet the selection criteria and were included in the analysis. Eight of them provided quantitative assessments with five studies focusing on dimensional accuracy of 3D printed models in replicating renal anatomy and tumour, and on measuring tumour volume between 3D printed models and original source images and surgical specimens, with mean difference less than 10%...

OBJECTIVE: Faculty evaluations, ABSITE scores, and operative case volumes often tell little about true resident performance. We developed an objective structured clinical examination called the Surgical X-Games (5 rooms, 15 minutes each, 12-15 tests total, different for each postgraduate [PGY] level). We hypothesized that performance in X-Games will prove more useful in identifying areas of strength or weakness among general surgery (GS) residents than faculty evaluations, ABSITE scores, or operative cases volumes...

The healthcare simulation (HCS) community recognizes the importance of quality management because many novel simulation devices and techniques include some sort of description of how they tested and assured their simulation's quality. Verification and validation play a key role in quality management; however, literature published on HCS has many different interpretations of what these terms mean and how to accomplish them. The varied use of these terms leads to varied interpretations of how verification process is different from validation process...

Objective: Improving medication adherence among children with B-cell precursor acute lymphoblastic leukemia (B-ALL) has the potential to reduce relapse rates but requires an investment in resources. An economic evaluation is needed to understand the potential costs and benefits of delivering adherence-promotion interventions (APIs) as part of standard clinical care. Methods: A Markov decision analytic model was used to simulate the potential incremental cost-effectiveness per quality-adjusted life year (QALY) to be gained from an API for children with B-ALL in first continuous remission compared with treatment as usual (TAU, no intervention)...

Quantitative phase imaging has been investigated to retrieve optical phase information of an object, and applied to biological microscopy and related medical studies. In recent examples, differential phase contrast (DPC) microscopy can recover phase image of thin sample under multi-axis intensity measurements in wide field scheme. Unlike conventional DPC, based on theoretical approach under partially coherent condition, we propose a new method to achieve isotropic differential phase contrast (iDPC) with high accuracy and stability for phase recovery in simple and high-speed fashion...

The population of people with a single-ventricle is continually increasing due to improvements across the spectrum of medical care. Unfortunately, a proportion of these patients will develop heart failure. Often, for these patients, mechanical circulatory support (MCS) represents the only available treatment option. While single-ventricle patients currently represent a small proportion of the total number of patients who receive MCS, as the single-ventricle patient population increases, this number will increase as well...

Reactive oxygen and nitrogen species released by cold physical plasma are being proposed as effectors in various clinical conditions connected to inflammatory processes. As these plasmas can be tailored in a wide range, models to compare and control their biochemical footprint are desired to infer on the molecular mechanisms underlying the observed effects and to enable the discrimination between different plasma sources. Here, an improved model to trace short-lived reactive species is presented. Using FTIR, high-resolution mass spectrometry, and molecular dynamics computational simulation, covalent modifications of cysteine treated with different plasmas were deciphered and the respective product pattern used to generate a fingerprint of each plasma source...

Vaccine safety studies are often electronic health record (EHR)-based observational studies. These studies often face significant methodological challenges, including confounding and misclassification of adverse event. Vaccine safety researchers use self-controlled case series (SCCS) study design to handle confounding effect and employ medical chart review to ascertain cases that are identified using EHR data. However, for common adverse events, limited resources often make it impossible to adjudicate all adverse events observed in electronic data...

Digital microfluidic is an emerging technology to reduce the cost and time of experiments and improve the flexibility, automate-ability and correctness of biochemical assays. In many of applications such as drug discovery and DNA profiling, a large number of bio-operations (e.g. the chemical operations used in biology applications) must be done. In these applications, parallelising the operations will be critical in accuracy and cost of the process and digital microfluidic biochips can be considered as a reasonable platform...

Anesthesia simulations have been used in pre-clinical medical training for decades to help learners gain confidence and expertise in an operating room environment without danger to a live patient. The authors describe a veterinary anesthesia simulation environment (VASE) with anesthesia scenarios developed to provide a re-creation of a veterinarian's task environment while performing anesthesia. The VASE uses advanced computer technology with simulator inputs provided from standard monitoring equipment in common use during veterinary anesthesia and a commercial canine training mannequin that allows intubation, ventilation, and venous access...

In recent years, there has been a growing need for skills quantification of endoscopic specialist. Various educational simulators have been created to help increase the endoscopy performance of medical students and trainees. Recent research seems to show that the use of simulators helps increase the skill level of endoscopists, while improving patient safety 1, 2 . However, previous simulators lack sufficient realism and are unable to replicate natural human reactions during endoscopy or quantify endoscopic skills...

BACKGROUND: Paediatric laparoscopic procedures are now becoming routine practice. Therefore, there is a need for simulated laparoscopic models to acquire part-procedural competency prior to direct patient contact in a safe learning environment. For this reason, we chose two paediatric conditions; inguinal hernia (IH) and congenital diaphragmatic hernia (CDH), which were combined to create the laparoscopic inguinal and diaphragmatic defect (LIDD) model. Our aim was to assess this novel surgical simulation model by determining its construct and content validity...

Introduction: Non-interventional and other observational studies have become important in medical research. In such observational, non-randomized studies, groups usually differ in some baseline covariates. Propensity scores are increasingly being used in the statistical analysis of these studies. Stratification, also called subclassification, based on propensity scores is one of the possible methods. There is the quasi-standard of using five strata. In this paper we focus on a binary outcome and evaluate the above-mentioned standard of using five strata...
