Background/Objectives: Sepsis is a costly and life-threatening condition caused by a dysregulated host response to infection. Lack of a reliable, timely diagnostic for sepsis leads to under- and overdiagnosis, suboptimal outcomes, and strained hospital resources. Our Lady of the Lake Regional Medical Center (OLOLRMC) implemented a sepsis learning health program to evaluate and improve outcomes through standardized ED workflows and the incorporation of a novel sepsis diagnostic test. Methods: We report the results of the first year of experience following the implementation of the learning health initiative and sepsis testing. Data from the Epic EHR were analyzed across two groups: …

Steps Toward Clinical Validation Of Exhaled Volatile Organic Compound Biomarkers For Hypoglycemia In Persons With Type 1 Diabetes., Mark Woollam, Paula Angarita-Rivera, Sanskar Thakur, Ali Daneshkhah, Amanda P Siegel, Dana S Hardin, Mangilal Agarwal

Ambulatory and Primary Care Articles

Persons with type 1 diabetes (T1D) must track/control their blood glucose (BG) levels to avoid hypoglycemic events (BG <  70 mg/dL), which in the most severe cases can lead to seizures or even death. Canines may lead the way toward innovative testing solutions, as they can be trained to identify hypoglycemia simply and noninvasively by smelling exhaled volatile organic compounds (VOCs). To identify breath-based biomarkers of hypoglycemia, samples were collected during two consecutive summers at a diabetes camp (Cohort 1 and Cohort 2), and VOCs were analyzed by gas chromatography-mass spectrometry. Conserved VOCs between the two cohorts were identified, but individual VOCs alone had low accuracies for detection. Therefore, supervised multivariate statistical analysis was undertaken to identify a biosignature in the training data set (Cohort 1) that could detect hypoglycemia with higher accuracy (sensitivity = 94.8%/specificity = 95.0%). When this model was blindly tested on Cohort 2, hypoglycemia was classified with sensitivity = 90.0%/specificity = 89.9%. Ultimately, this study makes strides toward clinical validation through verifying biomarkers of hypoglycemia in hundreds of breath samples. These results may be translated to design a sensor array that could be integrated into a portable breathalyzer to increase glycemic control in persons with T1D.

Surrogate Trust In The Intensive Care Unit: What Can We Do Better?, Abdul W. Kazi, Phoebe Chun, David Oxman, Erika J. Yoo

Department of Medicine Faculty Papers

BACKGROUND/OBJECTIVES: Previous investigation into patients' trust in medical providers is largely limited to the outpatient setting, where increased trust is associated with improved adherence, satisfaction, and self-reported quality of life. Contrastingly, in the intensive care unit (ICU), patients are frequently incapacitated, and it is surrogates that engage with clinicians for decision making. This pilot study aims to measure and compare surrogate trust in the healthcare system and ICU physicians.

METHODS: We measured surrogate trust in both the healthcare system and providers by administering two domain-specific trust-measuring surveys (the Healthcare System Distrust Scale and a modified Trust in Physicians Scale) to …

When The Right Ventricle Fails After Left Ventricular Assist Device Implantation: Prediction Tools, Recognition Strategies, And Support Options, Juan Jose Rodriguez Arias, James Schurr, Phyllis Billia, Joyce W. Wald

Journal of Shock and Hemodynamics

The incidence of right heart failure (RHF) during durable left ventricular assist device (LVAD) surgery ranges from 9% to 42%, depending on the definition. RHF can be divided into three peri-implantation categories: early acute, early, and late. Despite many available risk models, predicting RHF before durable LVAD implantation has been difficult. Preemptive right-sided temporary mechanical circulatory support can improve outcomes; however, if intraoperative RHF is not suspected, early recognition and appropriate intervention after surgery are important.

Reducing Overnight Interruptions For Nonurgent Electrolyte Repletion, M. Duncan Kilpatrick, Md, Trishya Srinivasan, Md, Bertilia Tavarez, Md, Tatianna Branch, Do, Edwin Perez, Md, Zachary Pang, Md, Ryan Gardner, Md, Daniel Taupin, Md

Health Equity and Quality Improvement (HEQI) Summit

Background

• Overnight patient interventions, including electrolyte repletion, contribute to hospital acquired delirium.¹
• Among patients admitted to TJUH, we identified many cases of IV magnesium (Mg) repletion given overnight, waking up patients when urgent repletion may not be clinically necessary.
• This may be driven by resident belief that IV Mg increases serum Mg more effectively than PO Mg
• TJUH has implemented the Electrolyte Hub in EPIC which standardizes the dosing and ordering of electrolytes in most cases.
• However, the default in most non urgent cases is to administer the first dose of electrolyte now, whether it is PO or IV. …

Improving The Quality Of Internal Medicine Discharge Summaries Via Accurate Admission Medication Reconciliation, Natasa Kostic, Md, Tammy Tran, Md, Kenneth Meserole, Md, Jon Zaid, Md

Health Equity and Quality Improvement (HEQI) Summit

Background

• Transitions of care are a time of vulnerability for patients.
• Nearly 20% of patients experience an adverse event within 3 weeks of hospital discharge, with adverse drug events being the most common.
• Discharge (DC) summaries serve to provide safe transition of care by describing hospital course and medication changes for review by outpatient providers.
• At TJUH, DC summaries are completed by internal medicine (IM) senior residents, but there is variability in quality of hospital course and thoroughness of medication reconciliation.
• Inaccurate admission medication reconciliation may lead to inaccurate reporting of discharge medication lists, causing confusion for both patients and …

The University of Louisville Journal of Respiratory Infections

Introduction: Bronchiectasis, currently being recognized worldwide, is an abnormal dilatation of the bronchi and bronchioles brought on by recurrent cycles of inflammation and airway infection. Impaired pulmonary function has a predictive significance in bronchiectasis. When treating patients with suspected or confirmed respiratory diseases, pulmonary function tests (PFT) are useful examinations. Very few studies have been done on PFTs in bronchiectasis. The main aim of this study is to study PFTs in bronchiectasis.

Method: This is a retrospective observational study done on 50 patients over two years at the tertiary care center. The previous records of patients were collected from the …

Division of Internal Medicine Faculty Papers & Presentations

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome (ACS), which predominantly affects women. This case report describes a 55-year-old female with SCAD potentially linked to a progestin-releasing intrauterine device (IUD) placed 1.5 years ago. The patient presented with acute chest pain and diaphoresis, and was eventually found to have ST-elevation myocardial infarction that led to coronary angiography, revealing type 1 SCAD from the proximal right coronary artery (RCA) to the mid-RCA with grade 3 thrombolysis in myocardial infarction (TIMI) flow distally. She was managed conservatively with antithrombotics, statins, and blood pressure control, achieving favorable outcomes …

Forward Genetic Screen In Zebrafish Identifies New Fungal Regulators That Limit Host-Protective Candida-Innate Immune Interaction, Bailey A Blair, Emma Bragdon, Gursimran Dhillon, Nnamdi Baker, Lena Stasiak, Mya Muthig, Pedro Miramon, Michael C Lorenz, Robert T Wheeler

Faculty, Staff and Student Publications

Candida is one of the most frequent causes of bloodstream infections, and our first line of defense against these invasive infections is the innate immune system. The early immune response is critical in controlling Candida albicans infection, but C. albicans has several strategies to evade host immune attack. Phagocytosis of C. albicans blocks hyphal growth, limiting host damage and virulence, but how C. albicans limits early recruitment and phagocytosis in vertebrate infection is poorly understood. To study innate immune evasion by intravital imaging, we utilized the transparent larval zebrafish infection model to screen 131 C. albicans mutants for altered …

Small Steps For A Big Change: A Longitudinal Project To Enhance Well-Being Of Internal Medicine Residents, Vandana Nagpal, Benjamin Tanenbaum, Christine Runyan

Journal of Wellness

Introduction: Residency training is demanding and often leads to burnout. In 2017, Internal Medicine (IM) residents at our institution reported a poor collective residency experience. In response, we launched a longitudinal wellness program in 2018, featuring multi-pronged interventions to improve residents' well-being. The program, still active today, has undergone iterative modifications with ongoing input from residents.

Approach: The resident-led Wellness Committee was established in 2018, and the following no to low-cost initiatives were implemented sequentially: quarterly group sessions with an institutional health psychologist, bi-annual self-checks, peer buddy support for incoming first-year residents, weekly 5-minute reflection sessions, and volunteer dog visits. …

Can Anemia Be A Prognostic Indicator To Scope For Gastroesophageal Junction Adenocarcinoma?, Ryan Tam, Neha Narayanan, Evan Basha, Joel Thompson

Advances in Clinical Medical Research and Healthcare Delivery

Gastroesophageal junction adenocarcinoma is a rapidly progressive disease that has a poor prognosis with a 5-year survival rate of 20%. It commonly presents with major symptoms of dysphagia and weight loss in addition to a long-standing history of reflux. As of now, screening for esophageal adenocarcinoma (EAC) is dependent on identifying risk factors which include a family history of Barrett’s esophagus and esophageal adenocarcinoma or patients with gastroesophageal reflux disease and at least one other risk factory for EAC such as age greater than 50 years, obesity or central adiposity, history of smoking, or male gender. Here, we present a …

Intractable Hiccups As The Presenting Symptom Of Relapsed Salmonella Bacteremia Complicated By Salmonella Endocarditis, Sahej Arora, Tripti Jain, Hafsa Jawaid, Nada Hafez, Binita Neupane

Advances in Clinical Medical Research and Healthcare Delivery

Salmonella infections are generally acute diarrheal illnesses that uncommonly spread to deeper or endovascular tissues, with key symptoms being nausea, vomiting, diarrhea, abdominal pain and fever. We present a case of a 76-year male who presented chiefly with recurrent intractable hiccups after finishing two weeks of oral ciprofloxacin for a previous episode of Salmonella bacteremia. He was ultimately found to have an aortic root vegetation on transesophageal echocardiogram and focal adenomyomatosis on gallbladder ultrasound. He underwent cholecystectomy, aortic valve replacement and six weeks of antibiotic therapy with resolution of his hiccups. Our case demonstrates an atypical symptom of intractable hiccups …

Mirizzi Syndrome: A Case Report, Elizabeth Barr, Keng Moua, Kavitha Vemuri

Advances in Clinical Medical Research and Healthcare Delivery

Mirizzi syndrome is a rare complication of chronic gallstone disease that occurs when an impacted gallstone at the gallbladder infundibulum or cystic duct causes common extrinsic hepatic or common bile duct obstruction. Contrary to other gallstone pathologies where gallstones affect the respective location in which they are lodged, Mirizzi syndrome is unique in that it is characterized by extrinsic gallstone compression. Chronic gallstone disease most commonly leads to acute cholecystitis, acute cholangitis, or acute pancreatitis. The extrinsic compression of the common hepatic or common bile duct may lead to eventual erosion which increases the risk for a cholecystocholedochal or cholecystohepatic …

A Budding Pancreatic Mass: A Review Of Disseminated Blastomycosis, Tina C. L. Phan, Chloe N. Hundman, Neena Thomas-Gosain, Christopher D. Jackson

Journal of Community Hospital Internal Medicine Perspectives

A 67-year-old male patient presented with anorexia, weight loss, skin masses, and flank pain over the past three months. Imaging revealed a lung mass and a cystic lesion in the pancreatic head. After initial diagnostic work-up and clinical deterioration, broad based budding, seen on pathology, led to a diagnosis of disseminated blastomycosis. After receiving a 14-day course of liposomal amphotericin B followed by itraconazole, the patient showed significant clinical improvement. We reviewed all disseminated blastomycosis cases in the medical literature involving gastrointestinal organs. Although pancreatic involvement is rare, we suggest that it should be suspected in those with a rapidly …

Iron Deficiency—More Than Just Anemia: A Literature Review, Arianna S Moss, Zahra Pakbaz

Journal of Community Hospital Internal Medicine Perspectives

Iron deficiency (ID) is a global public health concern, as it can be a prodrome of gastrointestinal (GI) malignancies, exacerbate chronic conditions, and lead to an overall decreased quality of life. Despite being the most prevalent nutritional deficiency, it remains underdiagnosed by many healthcare professionals. Misconceptions regarding the clinical and laboratory manifestations of ID lead to delayed or missed diagnoses, contributing to poor patient outcomes. Though anemia is a commonly known consequence of ID, there are additional consequences that remain underrecognized by the medical community, including vague signs and symptoms, such as fatigue, depression, and abnormalities in white blood cell …

Preserving What Matters: A Multimodal Approach To Maintaining Fat-Free Mass During Anti-Obesity Medication Based Weight Loss, Sarah Gore

Evidence-Based Practice Project Reports

Weight loss is often associated with reductions in fat-free mass (FFM), which can negatively impact metabolic rate, thermoregulation, bone density, functional capacity, and overall quality of life (Roth et al., 2022; Sedlmeier et al., 2021). This Evidence-Based Practice project aimed to reduce FFM loss in adults prescribed anti-obesity medications (AOMs) for weight management through a targeted, multimodal intervention. Twenty-two patients beginning AOM treatment at a family practice in northwest Indiana were invited to participate, with 19 consenting to enroll. Each participant received personalized guidance, including tailored calorie and protein intake goals to support a hypocaloric, high-protein diet, alongside evidence-based aerobic …

When Pressure Rises: Identifying Abdominal Compartment Syndrome Amid Critical Illness, Mariam Jamil, Muhammed Hussain, Amna Jafri, Asim Mohamed, Rajiv John

Conference Presentation Abstracts

Introduction Abdominal Compartment Syndrome (ACS) occurs in approximately 15% of patients with severe acute necrotizing pancreatitis and is associated with a poor prognosis. Treatment typically involves urgent decompressive laparotomy. However, diagnosing ACS in an intensive care unit (ICU) setting can be challenging, as patients often present with primary illnesses that independently drive end-organ dysfunction. This case highlights a diagnostic framework for ACS while emphasizing common pitfalls and challenges. Case Description A 54-year-old male with a history of alcohol abuse presented with a two-week history of abdominal discomfort and shortness of breath. Initial evaluation, including clinical examination, imaging, and laboratory findings, …
