Effect Of Sauna On Cardiovascular Health In Patients With Heart Failure, Rikuto Abe, Piotr Domaszewski, Safe Elhakeem
Effect Of Sauna On Cardiovascular Health In Patients With Heart Failure, Rikuto Abe, Piotr Domaszewski, Safe Elhakeem
Rowan-Virtua Research Day
Abstract
Heart failure (HF) is one of the hallmark diseases that represent a decline of cardiovascular function. Heart failure is characterized by a decrease in the ability of the heart to pump blood throughout the body, leading to symptoms such as fatigue, dyspnea, and swelling. HF is shown to decrease quality of life and increase mortality. Traditional treatments include pharmacology, lifestyle modifications, and surgery. Among the treatments, deliberate heat exposure in the form of dry saunas has been highlighted as a potential treatment option for HF. Dry saunas, especially infrared saunas, are shown to increase body temperature which improves circulation …

Impostor Phenomenon In Healthcare: Prevalence, Implications, And Educational Responses, James Espinosa, Robin Lahr, Sergey Medlenov, Swet Patel, Nicholas Tomasello, James Lee, Neel Parikh, Alan Lucerna, Henry Schuitema
Rowan-Virtua Research Day
The impostor phenomenon describes persistent self-doubt and fear of being exposed as a fraud despite objective evidence of competence. The term 'impostor phenomenon' is preferred over the term "imposter syndrome" because it is not a psychiatric diagnosis and avoids pathologizing normal developmental uncertainty. The original authors used the term 'phenomenon' (Clance & Imes, 1978), and contemporary scholarship increasingly adopts this terminology.
First described by Clance and Imes (1978), the construct has since been studied across diverse professional domains, including medicine, nursing, and academic leadership. Subsequent research demonstrates that impostor experiences occur across genders, training levels, and healthcare roles (Bravata et …
Gut Microbiota Dysbiosis In Down Syndrome: Implications For Gastrointestinal And Neurological Health, Ashlyn Mcclelland, Jennifer Lecomte, Wendy Aita, Andrea Iannuzzelli
Gut Microbiota Dysbiosis In Down Syndrome: Implications For Gastrointestinal And Neurological Health, Ashlyn Mcclelland, Jennifer Lecomte, Wendy Aita, Andrea Iannuzzelli
Rowan-Virtua Research Day
Down syndrome (DS) is the most common autosomal aneuploidy and has strong associations with increased gastrointestinal, neurological, and immune disorders. Emerging evidence suggests that gut microbiota dysbiosis may play a prominent role in disorders of gut-brain interaction, including constipation and irritable bowel syndrome affecting over half of individuals with DS. This review examines how gut microbiota alterations can contribute to chronic systemic inflammation and neurological manifestations in DS. Included articles were published between 2014 and 2025 and evaluated microbiota composition, inflammatory markers, and gastrointestinal or neurological outcomes in human or animal models of DS.
Across seven studies, characteristic microbiome shifts …
Learning From Our Dental Colleagues: A Brief Review Of Counter-Stimulation To Reduce Procedural Pain In Emergency Medicine Mechanisms, Existing Evidence, And A Pragmatic Research Agenda, James Espinosa, Neal Appelstein, Alan Lucerna
Learning From Our Dental Colleagues: A Brief Review Of Counter-Stimulation To Reduce Procedural Pain In Emergency Medicine Mechanisms, Existing Evidence, And A Pragmatic Research Agenda, James Espinosa, Neal Appelstein, Alan Lucerna
Rowan-Virtua Research Day
Counter-stimulation techniques such as tapping, pressure, vibration, and tissue shaking are commonly observed in dental practice during administration of local anesthetic nerve blocks. Although not systematically described in the Emergency Medicine literature, individual clinicians may employ tactile counter-stimulation techniques during needle-based procedures. The practice remains under-theorized and under-studied within the Emergency Medicine literature. This brief review synthesizes mechanistic neurobiology—including segmental gate control theory (Melzack & Wall, 1965), descending inhibitory modulation, and attentional salience models—with evidence from dental and needle-procedure research. We propose a practical taxonomy of counter-stimulation techniques applicable to Emergency Medicine and identify gaps in the current literature. Finally, …
From Confirmation To Guidance: Making The Case For Intraprocedural Pocus As The Next Developmental Step In Ultrasound-Supported Shoulder Reduction A Conceptual Practice Proposal And Research Agenda, James Espinosa
Rowan-Virtua Research Day
Point-of-care ultrasound (POCUS) is well established for the diagnosis of shoulder dislocation and for the confirmation of successful reduction. However, its role during the reduction maneuver itself remains under-described. This conceptual practice proposal argues that intraprocedural POCUS represents the logical next developmental step in ultrasound-supported shoulder reduction. By introducing real-time visualization of humeral head translation during reduction attempts, clinicians may identify ineffective vectors earlier, adjust technique midstream, and potentially reduce repeated attempts or escalation of procedural sedation. This work does not present outcome data but instead proposes a practical framework, workflow model, and research agenda for intraprocedural implementation. Future study …
In The Era Of The Smartphone: The Case For The Continued Role Of Mnemonics As Cognitive Scaffolds That Support Encoding, Working Memory Efficiency, And Rapid Cue-Dependent Retrieval, James Espinosa, Alan Lucerna
In The Era Of The Smartphone: The Case For The Continued Role Of Mnemonics As Cognitive Scaffolds That Support Encoding, Working Memory Efficiency, And Rapid Cue-Dependent Retrieval, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background: The ubiquity of smartphones and point-of-care digital references has prompted questions regarding the continued relevance of mnemonic devices in medical education. If information can be instantly retrieved, is memorization—and by extension mnemonic structure—still necessary? Objective: To reframe mnemonics not as relics of pre-digital pedagogy, but as cognitive scaffolds that support encoding, working memory efficiency, and rapid cue-dependent retrieval in time-pressured clinical environments. Discussion: Cognitive science demonstrates that working memory remains inherently limited regardless of technological access. Mnemonics function as structured chunks that reduce cognitive load, support pattern recognition, and facilitate transition from novice encoding to expert automaticity. In emergency …
Rainfall, Air Quality, And Vaso-Occlusive Crisis In Adults With Sickle Cell Disease, James Espinosa
Rainfall, Air Quality, And Vaso-Occlusive Crisis In Adults With Sickle Cell Disease, James Espinosa
Rowan-Virtua Research Day
.Patients with sickle cell disease (SCD) frequently report that weather changes precipitate vaso-occlusive crises (VOC). While prior investigations have focused primarily on temperature, humidity, and seasonal variation, emerging data suggest that rainfall patterns may represent a more meaningful environmental signal. In a multi-hospital Emergency Department analysis, below-average rainfall days were associated with significantly increased adult VOC presentations (Ahmed et al., 2023). Rainfall may function as an atmospheric clearing mechanism; reduced precipitation may permit accumulation of airborne particulate matter and environmental pollutants, increasing oxidative stress and endothelial activation—mechanisms central to vaso-occlusion. Multiple epidemiologic studies demonstrate associations between particulate exposure and increased …
Air Quality, Atmospheric Pressure, And Migraine Presentations In The Emergency Department, James Espinosa, Alan Lucerna
Air Quality, Atmospheric Pressure, And Migraine Presentations In The Emergency Department, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background: Migraine is a leading cause of Emergency Department (ED) visits and global disability. Weather has long been reported by patients as a trigger, yet the literature remains inconsistent. Prior ED-based data demonstrated an association between higher mean barometric pressure and increased migraine presentations, without a relationship to short-term pressure change. Because high-pressure systems are frequently associated with atmospheric stagnation and pollutant accumulation, air quality may represent a biologically plausible mediator.
Objective: To examine the relationship between air quality and ED migraine presentations within the existing body of literature and to explore whether air quality may help explain previously observed …
The Complex World Of Emergency Department Medication Dosing: Weight Scalars, Dose And Area Under The Curve (Auc) In Medication Dosing--Areas For Future Research, James Espinosa, Alan Lucerna
The Complex World Of Emergency Department Medication Dosing: Weight Scalars, Dose And Area Under The Curve (Auc) In Medication Dosing--Areas For Future Research, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Weight-based dosing is foundational to emergency medicine practice. With modern ED beds capable of automatic patient weighing, inaccuracies in estimated weight have largely diminished. However, medication misalignment persists, particularly in patients at extremes of body weight and in high-stakes clinical contexts such as rapid sequence intubation (RSI), antimicrobial therapy, and anticoagulation. Emerging pharmacokinetic literature emphasizes total drug exposure—represented by the area under the concentration–time curve (AUC)—as a stronger correlate of efficacy and toxicity than single-point serum levels. This review explores where weight precision most likely matters in the ED, examines weight scalars, and reframes dosing decisions through an exposure-centered paradigm. …
Listening To The System: Reframing Emergency Department Noise: The Case For Noise As A Real-Time Operational Signal In A Complex Adaptive System (Cas), James Espinosa, Alan Lucerna, Henry Schuitema
Listening To The System: Reframing Emergency Department Noise: The Case For Noise As A Real-Time Operational Signal In A Complex Adaptive System (Cas), James Espinosa, Alan Lucerna, Henry Schuitema
Rowan-Virtua Research Day
Emergency Department (ED) noise has historically been framed as an occupational and environmental hazard requiring mitigation. And this is still true—but not complete. Early work focused on exposure reduction and spike identification. Subsequent mapping studies demonstrated spatial and temporal differentiation in ED acoustic load. We propose an expanded conceptual model: acoustic variability may function not only as a hazard, but also as a real-time signal of operational turbulence within the ED as a complex adaptive system (CAS). Drawing on human factors, alarm fatigue, resilience engineering, and complexity science, we synthesize existing literature and institutional experience to identify a critical gap—noise …
Reset To Learn For Ite And Boards: The Neurobiology Supporting The Advantage Of Micro-Breaks During Content-Dense Lectures--And Why Continuous (No Micro-Breaks) Test-Bank Studying And Test-Taking ("Plowing Through") Is Suboptimal, James Espinosa, Robin Lahr, Swet Patel, James Lee, Alan Lucerna, Henry Schuitema
Reset To Learn For Ite And Boards: The Neurobiology Supporting The Advantage Of Micro-Breaks During Content-Dense Lectures--And Why Continuous (No Micro-Breaks) Test-Bank Studying And Test-Taking ("Plowing Through") Is Suboptimal, James Espinosa, Robin Lahr, Swet Patel, James Lee, Alan Lucerna, Henry Schuitema
Rowan-Virtua Research Day
Background: Working memory is a limited-capacity system vulnerable to saturation during sustained cognitive effort. In medical education, board review lectures, intensive test-bank studying, and prolonged examination sessions require extended executive control engagement. Emerging evidence from cognitive neuroscience suggests that brief, intentional cognitive disengagement ('micro-resets') of even 90 seconds may restore working memory efficiency and improve encoding, integration, and retrieval. This applies to brief breaks during content-dense lectures (needs support of lecturer), during test bank use for preparation as well as for test-taking. Objective: To propose a neurocognitive framework explaining why structured micro-breaks of even 90 seconds can enhance learning during …
The Neurobiology Of Interruptions In Emergency Medicine: The Case For Informed Interruption Management In Support Of Cognitive Stability In High-Reliability Clinical Environments, James Espinosa, Henry Schuitema, Alan Lucerna
The Neurobiology Of Interruptions In Emergency Medicine: The Case For Informed Interruption Management In Support Of Cognitive Stability In High-Reliability Clinical Environments, James Espinosa, Henry Schuitema, Alan Lucerna
Rowan-Virtua Research Day
Background: Interruptions are ubiquitous in Emergency Departments (EDs) and have been associated with task delay, multitasking, and increased error risk. While operational and human-factors impacts are well described, the underlying neurocognitive mechanisms remain underexplored. Not all interruptions are avoidable. However, interruptions in emergency medicine represent neurocognitive destabilization events that can degrade task representation and increase vulnerability to error during task resumption. Recognizing the neural mechanisms underlying interruptions reframes their management as a systems-level patient safety priority. The aim is not elimination of clinically necessary communication, but thoughtful reduction, prioritization, and design that protects cognitive stability.
Objective: To synthesize cognitive neuroscience …
Wildfires And Emergency Department Respiratory Surge: Brief Review, Systems Forecasting Implications And Recommendations For Research, James Espinosa, Alan Lucerna
Wildfires And Emergency Department Respiratory Surge: Brief Review, Systems Forecasting Implications And Recommendations For Research, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background: Wildfire smoke produces abrupt increases in PM2.5 and Air Quality Index (AQI) levels. Event-based and multi-season studies demonstrate short-term increases in asthma-related Emergency Department (ED) visits, with additional evidence supporting increased utilization for broader respiratory disease and chronic lower respiratory disease (including COPD) (Reid et al., 2016; Liu et al., 2015; Stowell et al., 2025; CDC, 2023).
Objective: To synthesize current evidence linking wildfire smoke to ED respiratory surge and to propose a systems forecasting model that translates environmental signals into structured operational stabilization within a complex adaptive system (CAS).
Methods (Review & Model Development): Narrative synthesis of event-based …
The Physics And Biology Of High-Risk Falls: Biomechanical Analysis And Physics Assists In Understanding Why The Threshold For High-Risk Was Lowered To 10 Feet, James Espinosa, Alan Lucerna
The Physics And Biology Of High-Risk Falls: Biomechanical Analysis And Physics Assists In Understanding Why The Threshold For High-Risk Was Lowered To 10 Feet, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background: Recent revisions to the National Guideline for the Field Triage of Injured Patients lowered the high-risk fall threshold from >20 feet to >10 feet for all ages. Guideline changes are multifactorial and typically reflect epidemiologic registry data, injury severity trends, and systems-level performance feedback. However, biomechanical analysis assists in understanding the importance of the change.
Objective: To demonstrate that a 10-foot fall generates sufficient kinetic energy and deceleration forces to exceed structural tolerance thresholds in multiple human tissues, and to show that fundamental physics independently supports the recent trauma protocol change.
Methods: Application of gravitational motion equations (v = …
Stroke Mimics And Stroke Chameleons: Leveraging The False Positive/False Negative Diagnostic Schema In Resident Teaching, James Espinosa, Alan Lucerna
Stroke Mimics And Stroke Chameleons: Leveraging The False Positive/False Negative Diagnostic Schema In Resident Teaching, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background
Stroke mimics and stroke chameleons contribute significantly to diagnostic uncertainty in Emergency Medicine. Traditional teaching often relies on enumerating examples, yet residents struggle to internalize these distinctions.
Objective
To present a conceptual teaching framework that maps stroke mimics to false positives and stroke chameleons to false negatives, leveraging pre-existing diagnostic schemas.
Methods
Using representative cases—including hypoglycemic hemiparesis and spinal epidural lipomatosis presenting as stroke mimic—we developed an explanation for residents involving framing mimics as false positives and chameleons as false negatives.
Results
Framing mimics as false positives and chameleons as false negatives activates existing learner schemas related to sensitivity …

Conceptualizing The Transition From Stable Operations To Turbulent States : Reframing Emergency Department Operations. Learning From Fluid Dynamics And Complexity Science, James Espinosa, David Ho, Alan Lucerna
Rowan-Virtua Research Day
Background: Emergency departments are frequently described using the language of patient flow, implying smooth and predictable movement of patients through a system versus known obstructions to flow. Clinicians, however, often observe abrupt shifts in operational stability.
Objective: To explore whether concepts from fluid dynamics and complexity science offer a useful framework for understanding these transitions.
Methods: Conceptual synthesis drawing on emergency medicine operations research, human factors, systems science, and fluid mechanics.
Results (Conceptual): Emergency departments exhibit behaviors analogous to systems approaching turbulence, including sensitivity to perturbation, amplification of delays, and nonlinear responses.
Conclusion: Viewing ED operations through the lens of …
The Ones That Got Away:Shared Misses, Shared Mastery — A Proposal For Leveraging Spaced Retrieval, Variable Reinforcement, And Collective Learning In Emergency Medicine Residency, James Espinosa D, Robin Lahr, James Lee, Swet M. Patel, Alan Lucerna
The Ones That Got Away:Shared Misses, Shared Mastery — A Proposal For Leveraging Spaced Retrieval, Variable Reinforcement, And Collective Learning In Emergency Medicine Residency, James Espinosa D, Robin Lahr, James Lee, Swet M. Patel, Alan Lucerna
Rowan-Virtua Research Day
Background
Residents frequently engage in individual question-bank study for board preparation; however, missed questions are typically processed in isolation. Educational psychology demonstrates that spaced retrieval and variable reinforcement enhance durable learning. Psychological safety further supports collective sense-making in professional education . The addition of a periodic, structured, collective shared-review process model may leverage these principles within residency training.
Objective
To propose a resident-driven educational initiative that transforms individually missed board-style questions into a shared, psychologically safe learning stream that promotes durable knowledge retention and community-based mastery. The movement of this stream could be a chief resident responsibility, or could be …

Soundscapes (Ambient Sound, Noise, Music And Other Background Sound) In The Emergency Department: An Under-Theorized Environmental Modifier In A Complex Adaptive System, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background:
Music and ambient sound (including noise and other sounds) are frequently present in emergency departments (EDs), yet their role as environmental modifiers remains under-theorized. Existing literature largely examines background music, for example, in procedural or perioperative contexts, with limited attention to open, high-density, multi-agent acute care systems.
Objective:
To conceptualize auditory input as a dynamic environmental variable within the ED viewed as a Complex Adaptive System (CAS), integrating neurobiological mechanisms with systems-level implications.
Methods/Conceptual Approach: Narrative conceptual synthesis integrating neurobiology of auditory processing, affective neuroscience, cognitive load theory, and complexity science.
Results:

Beyond Traditional Emergency Medicine Residency Match Interviews: Behavioral Questions As Stress Tests For Resident Selection A Theory-Driven Micro-Assessment Framework For Detecting High-Value Traits, Alan Lucerna, James Lee, Robin Lahr, James Espinosa
Rowan-Virtua Research Day
Background: Traditional residency selection metrics incompletely capture behavioral traits essential for emergency medicine (EM) performance.
Objective: To propose a theory-driven framework using structured behavioral questions as stress tests to detect high-value traits.
Methods: Conceptual analysis of three standardized behavioral prompts assessing execution, systems thinking, and team orientation.
Results: Distinct response patterns align with observable domains associated with reliability, performance, and leadership.
Conclusion: Behavioral stress test questions offer a scalable, low-cost method to enhance residency selection processes.
Helping Waldo (The Poster) Be Found: Teaching Search Literacy, Discoverability And Search Engine Optimization As Core Scholarly Skills In Graduate Medical Education, James Espinosa, Alan Lucerna
Helping Waldo (The Poster) Be Found: Teaching Search Literacy, Discoverability And Search Engine Optimization As Core Scholarly Skills In Graduate Medical Education, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background: In modern academic medicine, trainees are taught how to search the biomedical literature but rarely taught how to structure their own scholarly work so that it can be discovered. This creates a diffusion gap in which high‑quality educational innovations, case reports, and operational insights remain difficult to locate despite being presented or archived.
Objective: To propose a concise educational module that teaches residents the principles of search literacy and scholarly discoverability.
Methods: A conceptual curriculum framework was developed drawing on literature from information science, medical education, and diffusion theory. The module introduces the paired competencies of 'Finding Waldo' (literature …

Constructive Affirmation: Proposing An Empowering Term For What Good Teaching Attendings Already Do-- Integrating Affirmation And Constructive Criticism Through Learning Science, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background
Feedback is central to residency training, and quite naturally many educational cultures emphasize corrective feedback and error identification. Learning science suggests that reinforcement of correct cognitive patterns is equally essential for expertise development. This paper introduces the concept of constructive affirmation as an integrated feedback model combining affirmation and constructive criticism.
Objective
To propose a learning science framework for clinical feedback in residency training centered on the concept of constructive affirmation.
Methods
This conceptual analysis synthesizes literature from medical education, cognitive psychology, neurobiology of learning, and complexity science to examine how different feedback types influence pattern recognition, cognitive load, …
Reframing Emergency Medicine (And Healthcare) Wellness Measures: The Case For Adding Measures Of Physiological Sustainability, Exercise, Restoration, And Meaning, James Espinosa, Alan Lucerna
Reframing Emergency Medicine (And Healthcare) Wellness Measures: The Case For Adding Measures Of Physiological Sustainability, Exercise, Restoration, And Meaning, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background
Physician wellness measurement in Emergency Medicine (EM) in particular and in healthcare in general has largely focused on identifying distress states such as emotional exhaustion and depersonalization. Instruments such as the Maslach Burnout Inventory and related derivative surveys have been well-validated and have played a central role in identifying the scope of burnout across healthcare systems.
Conceptual Framing
While current measures of distress are essential, they may not fully characterize the spectrum of clinician health. In many fields outside healthcare—including occupational health, resilience research, and positive psychology—assessment of well-being includes behaviors and experiences associated with sustained health, such as …
A Systems Perspective On Workstation Ergonomic Principles And Their Application In Emergency Care Environments, James Espinosa, Alan Lucerna
A Systems Perspective On Workstation Ergonomic Principles And Their Application In Emergency Care Environments, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background: Workstation ergonomic principles are commonly included in mandatory healthcare training programs. These recommendations—monitor height relative to eye level, neutral arm positioning, and adjustable seating—derive largely from occupational ergonomics literature designed to reduce musculoskeletal strain and improve comfort during computer work. Emergency Departments (EDs), however, represent dynamic environments with shared workstations and workflow interruptions that may influence the implementation of these recommendations.
Objective: To summarize the evidence supporting commonly taught workstation ergonomic principles and frame them within a systems perspective of ED work environments.
Methods: Narrative review of occupational ergonomics guidelines, ergonomic intervention studies, and human factors literature relevant to …
The Ed Is Inherently Interleaved: The Learning Theory Case For Hybrid Resident Conference Curriculum Design In Emergency Medicine: Block For Onboarding And For Specialized Topics With Predominant Interleaving For Intermediate And Advanced Residents, James Espinosa, Alan Lucerna
The Ed Is Inherently Interleaved: The Learning Theory Case For Hybrid Resident Conference Curriculum Design In Emergency Medicine: Block For Onboarding And For Specialized Topics With Predominant Interleaving For Intermediate And Advanced Residents, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background
Emergency medicine (EM) training occurs within a clinical environment characterized by rapid context switching, diagnostic uncertainty, and frequent transitions between unrelated clinical problems. Didactic curricula that rely only on block-based topic organization may not fully reflect the cognitive demands of real emergency department practice.
Objective
To propose a developmentally adaptive hybrid model of EM curricular design that integrates early block learning during the onboarding phase of new residents, progressing to a general approach of interleaved learning. Specialized topics, can be introduced using block learning at any time during the residency years.
Methods / Conceptual Approach
This conceptual educational model …
Congruence (Healthy Adaptation And Resilience) Under Stress: A Human Systems Model For Healthcare Microsystems Integrating Virginia Satir’S Communication Theory With Clinical Microsystems And Complex Adaptive Systems Using The Emergency Department As A Model Of Adaptive Team Function, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background:
Emergency departments operate as complex human systems under continuous cognitive, emotional, and operational stress. Healthcare delivery occurs within clinical microsystems—small frontline units where patients, clinicians, and staff interact directly. While microsystem theory has provided an operational framework for improving quality and safety, less attention has been given to the relational communication dynamics within these systems.
Objective:
To integrate Virginia Satir’s human systems theory with clinical microsystem theory and complex adaptive systems thinking in order to better understand communication patterns, team dynamics, and adaptive functioning within emergency medicine residency programs and ED clinical teams.
Conceptual Framework:
Satir described several communication …

Might Ite And Board Preparation Be Both Informative And Neurobiologically Formative? A Plausibility Argument Linking Study Processes To Hippocampal–Cortical Memory Consolidation, Pattern Recognition Networks, And Cognitive Efficiency, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background: The in-service training exam ( ITE ) and board preparation are traditionally framed as processes of information acquisition and evaluation. Educational discussions typically focus on knowledge transfer, study strategies, and examination performance. However, modern neuroscience suggests that sustained, emotionally salient, and repetitive cognitive challenge in adulthood can produce durable neuroplastic adaptations. Might such residency training be not only informative but also formative?
Objective: To propose a conceptual framework in which board preparation may be both informative and neurobiologically formative, functioning as a training environment that promotes integration of neural systems involved in memory retrieval, pattern recognition, and decision-making under …

The Epidemiology Of Sledding Injuries: Clinical Patterns And Public Health Prevention Strategies, James Espinosa, Alan Lucerna
Rowan-Virtua Research Day
Background: Sledding is a widely enjoyed winter recreational activity among children and adolescents. Although commonly perceived as low risk, sledding can result in extremity fractures, head injuries, and collision-related trauma. Emergency Departments frequently encounter sledding injuries during winter months, providing both clinical insight and opportunities for injury prevention counseling. An estimated 20,000–30,000 sledding-related injuries occur annually in the United States, most involving children and adolescents.
Objectives: To describe patterns of sledding injuries presenting to the Emergency Department and highlight practical safety recommendations physicians can communicate to families.
Methods: Conceptual review integrating Emergency Department observational experience with published literature on pediatric …
The Safety Paradox Of Emergency Department Shift Length: Why The Relationship Between Hours Worked And Patient Safety Is More Complex Than It Appears, James A. Espinosa Md, Alan Lucerna
The Safety Paradox Of Emergency Department Shift Length: Why The Relationship Between Hours Worked And Patient Safety Is More Complex Than It Appears, James A. Espinosa Md, Alan Lucerna
Rowan-Virtua Research Day
Background: Emergency department shift duration has long been debated as a determinant of patient safety. While longer shifts may increase cognitive fatigue, shorter shifts may increase the frequency of patient handoffs, which themselves introduce communication risk. Objective: To conceptualize emergency department shift length as a safety paradox arising from the balance between fatigue and handoff-related communication risks. Conceptual Framework: We propose the Emergency Department Shift Length Safety Paradox model illustrating the nonlinear relationship between shift duration and patient safety. Implications: Optimal shift design may depend on balancing fatigue risk and communication risk within a complex adaptive healthcare system. Conclusion: Emergency …
Emergency Medicine As A Complex Adaptive System Apprenticeship: A Conceptual Framework For Understanding The Development And Emergence Of Systems Leaders From The Field Of Emergency Medicine, James Espinosa, Alan A. Lucerna, Henry Schuitema
Emergency Medicine As A Complex Adaptive System Apprenticeship: A Conceptual Framework For Understanding The Development And Emergence Of Systems Leaders From The Field Of Emergency Medicine, James Espinosa, Alan A. Lucerna, Henry Schuitema
Rowan-Virtua Research Day
Background
Emergency physicians are frequently observed to assume leadership roles in hospitals and health systems. Prior literature, including policy and leadership analyses from the American College of Emergency Physicians, has described this phenomenon and highlighted the emergency department’s central position within hospital operations. However, most explanations focus on enumerating leadership competencies rather than identifying the developmental mechanism through which those competencies emerge.
Objective

Background: Many residency programs require scholarly output; however, consistent and high volume production of posters and publications can be challenging. Anecdotal evidence from a variety of programs suggests variability in outcomes across programs, often influenced by differences in mentorship, structure, and available scholarly infrastructure. Objective: To describe a reproducible, systems-based model for generating high-volume resident scholarly output through alignment of expectations, culture, infrastructure, and faculty engagement. Methods and Conceptual Model: We outline a multi-domain framework derived from sustained programmatic experience, incorporating structural requirements, leadership alignment, cultural reinforcement, workflow standardization, and active faculty participation. The model is supported by practical tools …
