Enhancing Resident Preparedness For The American Board Of Surgery Certifying Exam Through Low-Stakes Mock Oral Sessions, Camila R. Guetter, Taylor Locklear, Omar Haque, P Nina Scalise, Saptarshi Biswas, R. Wesley Vosburg

HCA Healthcare Journal of Medicine

Background

The American Board of Surgery (ABS) requires trainees to pass both a written qualifying examination (ABSQE) and oral certifying examination (ABSCE) to achieve board certification. The high-stakes nature of the ABSCE, which assesses knowledge, clinical judgment, and decision-making, necessitates extensive preparation. To address the challenges of the ABSCE format and associated trainee stress, structured mock oral programs have been developed. Here we evaluate the impact of structured mock oral sessions on residents' comfort levels and familiarity with the ABSCE at a single institution.

Methods

A mixed-methods survey was given to 50 general surgery residents in different training years who …

Severe Chemotherapy-Induced Peripheral Neuropathy Presenting With Paraplegic Symptoms: A Rehabilitation Case Report, Cecilia Hammond, Elizabeth Campione

Knowledge Gaps In High-Energy Sacral Fracture Treatment And Management, Ashraf N. El Naga, Marko H. Neva, Ahmed Abdelazim Hassan, Gregory D. Schroeder, Mohammad El-Sharkawi, Sebastian F. Bigdon, Andrei F. Joaquim, Klaus Schnake, Richard Bransford, Emre Yilmaz

Rothman Institute Papers

High-energy sacral fractures (HESF) are often challenging injuries due to the location of the sacrum at the junction of the spine and pelvis, the complex biomechanics of the pelvic ring and the wide spectrum of injury patterns, which make treatment standardization challenging. Despite advances in classification systems - particularly the AOSpine Sacral Injury Classification - significant gaps remain in understanding optimal management. To review and discuss the management and identify knowledge gaps related to HESF. A narrative review of the literature was conducted, focusing on five domains: 1. Relative instability and biomechanics affected in different injury patterns; 2. The significance …

Occupational Stressors And Health Impacts Among First Responders, Mason N. Roach

Honors College Theses

The United States 911 emergency response system is an interconnected web of public services that seeks to provide its community with care, resources, and safety in times of need. However, the impact of this support on the employees providing the service often goes unnoticed. This review identifies and analyzes the unique strains on first responders' physical and mental health using the Job Demand-Control Model and the Allostatic Load Model. A review of available research literature supports the conclusion that occupational-related stress, including trauma exposure, shift work, poor leadership, and inadequate communication, can have long-lasting negative impacts on provider health.

Extrapulmonary Small Cell Carcinoma Presenting As Bilateral Papilledema, Hyponatremia, Encephalitis, Seizures, Crmp5-Igg Reactivity, And Prominent Anterior Tubular Perivascular Spaces, Ramsis Benjamin, Drew Thomas, Nina Mourao, J. Judd Fite, Brianna Woodliff, Shubhank Goyal

School of Medicine Publications

Background: Paraneoplastic syndromes that affect both the optic disc and the brain parenchyma typically harbor antibodies directed toward CV2/collapsin response-mediator protein 5 (anti-CRMP5), amphiphysin, Ma antigen 2 (Ma2/Ta), and Yo. The most common cancers linked to anti-CRMP5 antibodies include small-cell lung carcinoma (SCLC), followed by thymoma, renal cell carcinoma, and thyroid papillary carcinoma. A long-held belief explains papilledema as related to increased pressure within the subarachnoid space or the microvascular capillaries, but intracranial pressures within the normal standard range may exist in a person with a paraneoplastic syndrome and papilledema. The glymphatic system, a central waste-clearance conduit, may play a …

From Pages To Practice: Course Design For Integrative And Connected Learning, Prutha Deshpande

UNLV Best Teaching Practices Expo

The poster provides resources for the design of courses to incorporate considerable reading, paired with purposeful activities and reflection questions that deepen understanding of key points of learning, support knowledge transfer, and encourage dialogue and connection.

“Finding From The Field”—An Approach To Encourageexperiential And Epistemological Reflection, Julian Kilker

UNLV Best Teaching Practices Expo

The “Findings from the Field” teaching practice asks students to document and analyze experiences, locations, or artifacts encountered outside the classroom. While traditional field trips emphasize experiential learning by, ideally, linking course concepts to real-world experiences, this “Findings from the Field” approach extends this model through epistemological reflection guided by annotating observations. Students are prompted to consider not only what they observe, but how they know what they know, encouraging metacognition about observation, experience, and empirical research.

Reinforcement Learning Improves Llm Accuracy And Reasoning In Disease Classification From Radiology Reports, Yishu Wei, Yi Lin, Adam Flanders, George Shih, Yifan Peng

Department of Radiology Faculty Papers

Accurate disease classification from radiology reports is essential for many applications. While supervised fine-tuning (SFT) of lightweight LLMs improves accuracy, it can degrade reasoning. We propose a two-stage approach: SFT on disease labels followed by Group Relative Policy Optimization (GRPO) to refine predictions by optimizing accuracy and format without reasoning supervision. Across three radiologist-annotated datasets, SFT outperformed baselines and GRPO further improved classification and enhanced reasoning recall and comprehensiveness.

A Systematic Review And Meta-Analysis Finds That Psychological Well-Being Predicts All-Cause Mortality Independently Of Psychological Ill-Being., Max Genecov, David Yeager

Department of Psychiatry and Human Behavior Faculty Papers

BACKGROUND: Does psychological well-being (e.g. life satisfaction, happiness, meaning in life) predict the length of a person’s life, or are measures of well-being simply assessing the absence of ill-being (depression, loneliness, sadness) and are therefore redundant with ill-being measures? Individual studies have examined this question by measuring and controlling for both well-being and ill-being, but inconsistent findings have been reported. METHODS: A systematic review and random-effects meta-analysis was conducted on the literature of prospective longitudinal studies linking all-cause mortality to well-being. Studies that controlled for ill-being were compared to studies that did not control for ill-being to identify the unique …

An Exploration Of Drivers Of Sepsis Outcomes In Racial And Ethnic Minority Populations, Matthew Moritz, Omar Pandhair, Shelley Schoepflin Sanders

Books, Presentations, Posters, Etc.

RATIONALE: Race and ethnicity affect sepsis outcomes in unclear ways. Existing data is conflicting, with some studies suggesting minority patients do worse, while others did not show a difference in outcomes between these groups. We sought to investigate whether inequalities exist in sepsis outcomes for different racial and ethnic groups in our large hospital system and to characterize how they may manifest. METHODS: We performed a retrospective cohort study of adults diagnosed with sepsis and discharged from any of Providence’s 52 hospitals between January 1 and December 31, 2023. We grouped patients into ten different race/ethnicity groups including White, Black, …

Ecmo As A Bridge To Lung Transplant For Refractory Rapidly Progressive Interstitial Lung Disease, Matthew Moritz, Omar Pandhair

Books, Presentations, Posters, Etc.

Anti-melanoma differentiation-associated gene 5 (MDA-5) antibody is most frequently associated with dermatomyositis with various degrees of clinical manifestations including rapidly progressive interstitial lung disease (RP-ILD), inflammatory arthritis, vasculopathy, and other cutaneous findings. Clinically amyopathic dermatomyositis (CADM) is frequently associated with RP-ILD and has high mortality rates. Here we present a case of anti-MDA5 associated RPILD but without other features of dermatomyositis that did not respond to standard immunosuppressive therapy. A 41-year-old woman with recently diagnosed interstitial lung disease and polyarthritis previously on methotrexate presented with progressive dyspnea and worsening hypoxemic respiratory failure. She was previously admitted for respiratory failure two …

Hydroxocobalamin In Septic Shock Management – Should It Be Introduced Sooner?, Linh Tang Taylor, Md, Cameron Miles Long, Md, Omar Pandhair

Books, Presentations, Posters, Etc.

Introduction: Treating sepsis involves timely antibiotics, adequate fluid resuscitation, and vasopressor support if shock develops. Plasma concentrations of nitric oxide and hydrogen sulfides are elevated in early sepsis, contributing to vasoplegia,1 a pathology that isn’t addressed by vasopressors. High-dose hydroxocobalamin (vitamin B12) does, and therefore, has long been explored as a potential adjunct to vasopressors, though no consensus or official guidelines for its use have been published. Case Report: A 26-year-old man who was diagnosed with acute myeloid leukemia a few months prior presented to the emergency room for fever, weakness, and emesis. He was found to be profoundly hypotensive …

Books, Presentations, Posters, Etc.

Pulmonary lymphangitic carcinomatosis (PLC) accounts for approximately 8% of pulmonary metastases and is primarily associated with breast, lung, and gastric cancers. Chest radiographs are often nonspecific and normal in approximately 50% of cases. We present a case of PLC as an initial presentation of metastatic gastric adenocarcinoma. A 57-year-old White woman with prior tobacco use, asthma, and multiple sclerosis on Natalizumab presented with three months of progressive dyspnea and cough. She was evaluated multiple times and treated with various antibiotics and inhalers for presumed bronchitis. Despite this, her symptoms worsened, prompting hospital evaluation. She was tachycardic and markedly hypoxemic on …

Pulmonary Pseudomyxoma Peritonei, Hannah Kirk, Do, Omar Pandhair

Books, Presentations, Posters, Etc.

Introduction: Pseudomyxoma peritonei (PMP) is an intra -abdominal cancer occurring in one to four out of one million patients. It begins as a mucinous adenocarcinoma of the appendix that implants on other peritoneal surfaces, spreading into gelatinous ascites. Treatment consists of hyperthermic intraperitoneal chemotherapy (HIPEC) and cytoreductive surgery (CRS). Extra -abdominal metastases are rare. We present the case of a patient who underwent treatment for PMP and was found to have lung nodules over a decade later. Case Presentation: A 73 -year -old woman with pseudomyxoma peritonei presented to the emergency department with progressive dyspnea and unintentional weight loss. Twenty …

The Rash After The Remedy, Elaine Chen, Md

Books, Presentations, Posters, Etc.

Introduction: Trimethoprim/sulfamethoxazole (TMP/SMX) is a widely prescribed and generally well-tolerated antibiotic. Cutaneous reactions occur in up to 4% of patients, including morbilliform rash, urticaria, DRESS, Stevens-Johnson syndrome, and toxic epidermal necrolysis. More rarely, TMP/SMX can trigger leukocytoclastic vasculitis (LCV), a small-vessel vasculitis characterized by neutrophilic infiltration, fibrinoid necrosis, and leukocytoclasia. LCV typically manifests as palpable purpura on dependent areas. While often skin-limited, systemic involvement may occur. We present a case of TMP/SMX-induced LCV with multi-organ features. Case description: A 53-year-old healthy male presented to urgent care with dysuria. Urine culture grew pan-sensitive E. coli, and he completed a 7-day course …

When Jaundice Isn’T Just The Liver’S Fault: A Chilly Case Of Cold Autoimmune Hemolytic Anemia, Jennifer Wong, Do, Shahana Baig-Lewis, Md, Mph

Books, Presentations, Posters, Etc.

Introduction: Cold agglutinin disease (CAD), a subtype of autoimmune hemolytic anemia (AIHA), is characterized by IgM autoantibodies that target red blood cell antigens at low temperatures, leading to agglutination in cooler peripheral tissues and hemolysis. Predominately directed against the “I” or “i” antigens, cold agglutinins are commonly associated with Mycoplasma pneumoniae and infectious mononucleosis. Distinguishing warm AIHA from CAD can be challenging. Definitive diagnosis relies on antibody testing, with warm AIHA primarily involving IgG and CAD involving IgM. We report a case of CAD initially misattributed to drug-induced liver injury in the setting of a viral upper respiratory infection. Case …

Eosinophilic Fasciitis Masquerading As Myositis: A Diagnostic Challenge, Jennifer L. Wong, Do, Elizabeth S. Ballner, Do, Mary Elizabeth Swift-Taylor

Books, Presentations, Posters, Etc.

Introduction: Eosinophilic fasciitis (EF), or Shulman’s disease, is a rare disorder of unknown etiology and poorly understood pathogenesis. It is characterized by fibroblast activation and interleukin-driven eosinophilia. Early clinical features include limb or trunk erythema, non-pitting edema, and progressive fascial thickening, often producing an “orange peel” appearance. Eosinophilia is a prominent laboratory finding in the early phase, but diagnosis often requires a full-thickness skin-to-muscle biopsy. Systemic corticosteroids are first-line therapy, with methotrexate as the steroid -sparing agent for refractory disease. We present a unique and diagnostically challenging case of EF confirmed by histopathology. Case Presentation: A 56-year-old man presented with …

Closing The Gap: Standardizing Sepsis Management To Address Racial Disparities Across Oregon Providence Hospitals, Jennifer Wong, Do, Shelley Schoepflin Sanders, Md, Facp

Books, Presentations, Posters, Etc.

Introduction: Sepsis is a time-sensitive, life-threatening medical emergency affecting approximately 1.7 million adults annually in the United States, contributing to nearly 270,000 deaths and over $24 billion in healthcare expenditures. Delays in recognition and initiation of treatment can significantly increase mortality. Previous studies have identified persistent racial disparities in sepsis care, including lower rates of recognition as the principal diagnosis and delayed antibiotic initiation for Black patients compared with White patients. In alignment with Providence’s mission to provide compassionate, equitable care, Oregon Providence hospitals implemented a standardized “Sepsis Order Set” in all Emergency Departments (ED) to reduce treatment delays and …

Idiopathic Systemic Capillary Leak Syndrome With Shock And Compartment Syndrome Due To Influenza A, Jobe Ashby, Md, Katelyn Bobrowski, Do, Ryan Best, Md

Books, Presentations, Posters, Etc.

INTRODUCTION: Idiopathic systemic capillary leak syndrome (ISCLS) is a rare, poorly understood condition that leads to extreme pathology with severe but predictable complications. First described in 1960, ISCLS has been identified in about 260 case reports and is marked by a triad of hypotension, hypoalbuminemia, and hemoconcentration often preceded by upper respiratory tract infection. It is divided into distinct phases of prodrome, extravasation, and recovery. We present a case of a middle-aged woman who presented with influenza A infection and developed ISCLS needing ICU level care for shock and bilateral upper extremity compartment syndrome. DESCRIPTION: Our patient is a 49-year-old …

Sepsis Transitional Care Management: A Phone Call To Reduce Readmission Health Inequity, Linh Tang Taylor, Md, Erica Leser, Ms, Alyssa Nelson, Michelle Schoepflin Sanders, Md

Books, Presentations, Posters, Etc.

Introduction: Sepsis accounts for 52% of hospital admissions in the United States and is the leading cause of death among hospitalized patients1 . However, disparity exists among sepsis survivors with race being reported as a determinant of recovery2 . Such disparity exists in Providence Oregon 8 hospitals: Providence Black patients have higher sepsis readmission rates than White (12.93% vs 11.65%). Using modified community-based participatory research, data analysis, and stakeholder interviews, we identified one potential root cause of the disparity: Black patients being readmitted are not receiving our system's Transitional Care Management (TCM) services. We aim to eliminate the Black/White sepsis …

Ofatumumab Associated Legionella Pneumonia In A Young Multiple Sclerosis Patient, Jobe Ashby, Omar Panhair

Books, Presentations, Posters, Etc.

Ofatumumab is the only anti-CD20 IgG1κ human monoclonal antibody therapy for relapsing forms of multiple sclerosis (MS) that patients can self-administer subcutaneously. Anti-CD20 agents are biologic therapies that carry an increased risk of serious infections, but rarely Legionellosis. We present the case of a young man taking ofatumumab for his MS who developed Legionella pneumoniae pneumonia. A 30-year-old man with MS diagnosed two years prior, stable on ofatumumab, presented with fevers, cough, and hemoptysis. A week earlier, he developed fevers and myalgias after administering ofatumumab, but these symptoms persisted longer than usual. Though initial vital signs were normal, he appeared …

Books, Presentations, Posters, Etc.

INTRODUCTION: Spur Cell Anemia (SCA) is a rare underrecognized non-autoimmune hemolytic anemia occurring in severe liver disease with prognostic implications. Since the 1980s there have been only a few dozen case reports and clinical images concerning SCA. We present a case of a young man managed in the ICU with multiorgan failure and a masked diagnosis of SCA. DESCRIPTION: A 33-year-old man was found down and presented to the ICU with hematemesis and hemorrhagic shock. He required massive transfusion for bleeding esophageal varices that were later banded and an expanding thigh hematoma. He was diagnosed with alcohol induced liver cirrhosis …

Enhancing Gestational Diabetes Screening, Sataj Johnson, Daniel Ruegg

Books, Presentations, Posters, Etc.

Background: Gestational diabetes mellitus (GDM) screening is recommended between 24–28 weeks of gestation to allow timely diagnosis and treatment and reduce adverse maternal and neonatal outcomes. The two-step glucose tolerance testing method is supported by ACOG, though completion can be delayed due to the need for multiple tests. In 2024 at Providence Milwaukie Family Medicine Clinic, incomplete GDM screening occurred in 23.1% of patients, and incomplete two-step screening occurred in 33.3%, with an average completion time of 12 days. Objective: To increase completion rates of two-step GDM screening and reduce time between abnormal 1-hour and diagnostic 3-hour glucose tolerance tests …
