  • Filling the Core EPA 10 assessment void: A framework for individual assessment of Core Entrustable professional activity 10 competencies in medical students. AEM education and training Miller, D. T., Gibb, W., Caretta-Weyer, H., Ng, K., Sebok-Syer, S. S., Gisondi, M. A. 2022; 6 (6): e10787


    Objectives: The goal of this study was to develop and evaluate a novel curriculum and assessment tool for Core Entrustable Professional Activity (EPA) 10 competencies and entrustment scoring in a cohort of medical students in their emergency medicine (EM) clerkship using a framework of individualized, ad hoc, formative assessment. Core EPA 10 is an observable workplace-based activity for graduating medical students to recognize a patient requiring urgent or emergent care and initiate evaluation and management.Methods: This is a prospective, pretest-posttest study of medical students during their EM clerkship. Using the Thomas and Kern framework, we created a curriculum of simulation cases about chest pain/cardiac arrest and respiratory distress, which included novel assessment checklists, and instructional videos about recognizing and managing emergencies. Students were individually pretested on EPA 10 competencies using the simulation cases. Two raters scored students using standardized checklists. Students then watched instructional videos, underwent a posttest with the simulation cases, and were scored again by the two raters using the checklists. Differences between pretest and posttest scores were analyzed using paired t-tests and Wilcoxon signed-rank tests.Results: Seventy-three out of 85 (86%) students completed the curriculum. Mean scores from pretest to final posttest in the chest pain/cardiac arrest and respiratory distress cases significantly improved from 14.8/19 (SD 1.91), to 17.1/19 (SD=1.00), t(68)=10.56, p<0.001, and 8.5/13 (SD 1.79), to 11.1/13(SD 0.89), t(67)=11.15, p<0.001, respectively. The kappa coefficients were 0.909 (n=2698, p<0.001) and 0.931 (n=1872, p<0.001). Median modified Chen entrustment scores improved from 1b (i.e., "Watch me do this") to 2b (i.e., "I'll watch you") for the chest pain/cardiac arrest case (p<0.001) and 1b/2a (i.e., "Watch me do this"/ "Let's do this together") to 3a (i.e. "You go ahead, and I'll double-check all of your findings") for the respiratory distress case (p<0.001).Conclusion: A new directed curriculum of standardized simulation cases and asynchronous instructional videos improved medical student performance in EPA 10 competencies and entrustment scores. This study provides a curricular framework to support formative individualized assessments for EPA 10.

  • Direct Evidence of Plasticity within Human Primary Motor and Somatosensory Cortices of Patients with Glioblastoma NEURAL PLASTICITY Gibb, W. R., Kong, N. W., Tate, M. C. 2020; 2020: 8893708


    Glioblastoma multiforme (GBM) is a devastating disease without cure. It is also the most common primary brain tumor in adults. Although aggressive surgical resection is standard of care, these operations are limited by tumor infiltration of critical cortical and subcortical regions. A better understanding of how the brain can recover and reorganize function in response to GBM would provide valuable clinical data. This ability, termed neuroplasticity, is not well understood in the adult human brain. A better understanding of neuroplasticity in GBM could allow for improved extent of resection, even in areas classically thought to have critical, static function. The best evidence to date has demonstrated neuroplasticity only in slower growing tumors or through indirect measures such as functional MRI or transcranial magnetic stimulation. In this novel study, we utilize a unique experimental paradigm to show direct evidence of plasticity via serial direct electrocortical stimulation (DES) within primary motor (M1) and somatosensory (S1) cortices in GBM patients. Six patients with glioblastoma multiforme in or near the primary motor or somatosensory cortex were included in this retrospective observational study. These patients had two awake craniotomies with DES to map cortical motor and sensory sites in M1 and S1. Five of six patients exhibited at least one site of neuroplasticity within M1 or S1. Out of the 51 total sites stimulated, 32 (62.7%) demonstrated plasticity. Of these sites, 14 (43.7%) were in M1 and 18 (56.3%) were in S1. These data suggest that even in patients with GBM in or near primary brain regions, significant functional reorganization is possible. This is a new finding which may lead to a better understanding of the fundamental factors promoting or inhibiting plasticity. Further exploration may aid in treatment of patients with brain tumors and other neurologic disorders.

  • Plasticity of the Primary Motor Cortex in Patients with Primary Brain Tumors. Neural plasticity Kong, N. W., Gibb, W. R., Badhe, S., Liu, B. P., Tate, M. C. 2020; 2020: 3648517


    There are two neuron-level mechanisms proposed to underlie neural plasticity: recruiting neurons nearby to support the lost function (ipsilesional plasticity) and uncovering latent pathways that can assume the function that was lost (contralesional plasticity). While both patterns have been demonstrated in patient groups following injury, the specific mechanisms underlying each mode of plasticity are poorly understood. In a retrospective case series of 13 patients, we utilize a novel paradigm that analyzes serial fMRI scans in patients harboring intrinsic brain tumors that vary in location and growth kinetics to better understand the mechanisms underlying these two modes of plasticity in the human primary motor cortex. Twelve patients in our series had some degree of primary motor cortex plasticity, an area previously thought to have limited plasticity. Patients harboring smaller lesions with slower growth kinetics and increasing distance from the primary motor region demonstrated recruitment of ipsilateral motor regions. Conversely, larger, faster-growing lesions in close proximity to the primary motor region were associated with activation of the contralesional primary motor cortex, along with increased activation of the supplementary motor area. These data increase our understanding of the adaptive abilities of the brain and may lead to improved treatment strategies for those suffering from motor loss secondary to brain injuries.

  • Neuroplasticity: Insights from Patients Harboring Gliomas NEURAL PLASTICITY Kong, N. W., Gibb, W. R., Tate, M. C. 2016; 2016: 2365063


    Neuroplasticity is the ability of the brain to reorganize itself during normal development and in response to illness. Recent advances in neuroimaging and direct cortical stimulation in human subjects have given neuroscientists a window into the timing and functional anatomy of brain networks underlying this dynamic process. This review will discuss the current knowledge about the mechanisms underlying neuroplasticity, with a particular emphasis on reorganization following CNS pathology. First, traditional mechanisms of neuroplasticity, most relevant to learning and memory, will be addressed, followed by a review of adaptive mechanisms in response to pathology, particularly the recruitment of perilesional cortical regions and unmasking of latent connections. Next, we discuss the utility and limitations of various investigative techniques, such as direct electrocortical stimulation (DES), functional magnetic resonance imaging (fMRI), corticocortical evoked potential (CCEP), and diffusion tensor imaging (DTI). Finally, the clinical utility of these results will be highlighted as well as possible future studies aimed at better understanding of the plastic potential of the brain with the ultimate goal of improving quality of life for patients with neurologic injury.
