“Medical Cannabis”: Advising Patients While Navigating Medical Ethics And Limited Evidence, Anna-Maria South, Shanna L. Babalonis, Laura C. Fanucchi, Michelle R. Lofwall

Internal Medicine Faculty Publications

Cannabis is increasingly legalized in more areas of the USA and marketed under the misnomer “medical cannabis.” Yet, there are no official dosing guidelines or approved medical uses for plant cannabis by the Food and Drug Administration. Due to significant federal barriers, research on efficacy, safety, and adverse effects of cannabis is limited. Patients are interested in cannabis as potential treatment of medical issues and/or symptoms and clinicians should include a discussion of the risks of cannabis consumption. However, many risks are not yet known, and clinicians might be unaware of the emerging literature. This perspective summarizes the potential harms …

Tales From The Cryptogenic: A Case Of Recurrent Major Cryptogenic Stroke, Harpreet Matharu, Kennedy Aikins, Kumail Rizvi, Danielle Ford

North Texas GME Research Forum 2026

Background

It is estimated that 30 to 40% of all strokes have no identifiable cause; these are classified as cryptogenic strokes. Often, the unknown nature is secondary to delayed or incomplete investigation of cerebrovascular pathology. At times, strokes are considered truly cryptogenic as extensive stroke workup leads to no identifiable cause or etiology. Acute ischemic strokes in young adults without identifiable risk factors present a diagnostic and therapeutic challenge. Prompt recognition and treatment are critical to optimize outcomes.

North Texas GME Research Forum 2026

BACKGROUND: Transplant programs may submit exception requests to upgrade a listed patient’s priority, often anticipating a higher likelihood of accepting marginal or high-risk donor organs. This study explores whether exception request status is associated with increased risk tolerance in organ acceptance.

METHODS: We conducted a retrospective analysis using data from the Scientific Registry of Transplant Recipients (SRTR), focusing on adult patients (≥18 years) listed for heart transplantation. Statistical analyses were performed using SAS/STAT 14.1. Descriptive statistics summarized demographic and clinical variables. Baseline characteristics were compared between recipients with and without exception requests. Primary analysis: Mixed-effects linear regression was used to …

Cardiac Step-Down Unit (Csu), Two Failures Drive Suboptimal Vte Prevention: Quality Improvement, Jorim Parmar, Shakir Al-Ezzi, Anvi Manduva, Muhammad Suleman, Fahed Alsayed, Debra Medsker

North Texas GME Research Forum 2026

BACKGROUND: In the Cardiac Step-down Unit (CSU), two failures drive suboptimal VTE prevention: (1). over-ordering of SCDs in patients unlikely to benefit and (2). < 10% documented application when SCDs are truly indicated. Baseline data indicates that curbing over-ordering alone would reduce recorded non-compliance by >50%, revealing a clear opportunity for system redesign.

METHODS: To integrate the updated “3 Bucket” Risk Model assessment into the computerized physician order entry (CPOE) in order to delineate the prophylaxis for a given patient population. Once the manual risk assessment proves to be viable in increasing compliance, we can propose having the tool adopted into the CPOE system. Root Cause Analysis revealed that lack of standardized VTE risk stratification leads to inconsistent ordering practices – …

A Lethal Connection Uncovered: Direct Endoscopic Evidence Of A Primary Aortoenteric Fistula, Joel Mathews, Trina Lewis, Munazzah Kaleem, Long Hoang

North Texas GME Research Forum 2026

BACKGROUND: Primary Aortoenteric Fistulas (PAEFs) are a rare condition that occurs when the native aorta develops an abnormal connection with the gastrointestinal lumen. PAEFs tend to develop within the duodenum, specifically the distal region of the third part of the duodenum, which is retroperitoneal and is anterior to the aorta. Duodenal PAEFs can be difficult to diagnose and are often lethal, given their non-specific presenting symptoms and rapid progression to hemorrhagic shock.

CASE PRESENTATION: This case focuses on a 70-year-old male with a history of T4N2 colon adenocarcinoma with hemicolectomy, active smoking, and abdominal aortic aneurysm (AAA) who was transferred …

Esophageal Squamous Cell Carcinoma Incidentally Detected On Barium Swallow: A Case Report, Muhammad Rubeel Akram, Aditya Rao, Muhammad T. Siddique

North Texas GME Research Forum 2026

Background: Esophageal cancer is an aggressive malignancy with a poor prognosis, and has high rates of recurrence despite curative-intent therapy. While endoscopy with biopsy remains the gold standard for diagnosis, non-diagnostic imaging studies are performed when evaluating for dysphagia, and may bring to light underlying pathology, warranting further workup. Surgical resection following neoadjuvant chemoradiation is often performed, but postoperative complications and disease recurrence are important concerns. This case highlights the crucial role of early detection via imaging and the clinical burden associated with esophageal squamous cell carcinoma.

Case Presentation: A 76-year-old female presented with dysphagia and underwent a barium esophagogram, …

Prognostic Value Of Systemic Inflammatory Indices For Predicting Mace In Nstemi Patients Undergoing Pci, Boney Lapsiwala, Aditya Sharma, Usman Khan, Jorim Parmar, Justin Soloman, Veeranna Vibhuti, Mehdi Khalafi

North Texas GME Research Forum 2026

Background: Cardiovascular diseases (CVD) account for nearly one-third of global mortality, with ischemic heart disease caused by a mismatch between myocardial oxygen supply and demand. Despite advances in percutaneous coronary intervention (PCI) and contemporary pharmacotherapy, patients with non–ST-segment elevation myocardial infarction (NSTEMI) continue to experience substantial residual risk for major adverse cardiovascular events (MACE). As traditional risk stratification tools have limited ability to identify high-risk individuals, interest has shifted toward biomarkers reflecting inflammatory pathways central to atherosclerosis and plaque instability. Hematologic inflammatory markers including pan inflammatory value (PIV), systemic immune inflammation index (SII), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) initially …

A Not So Typical Case Of Alcoholic Pancreatitis, Wendy Phillips, Kaleem Munazzah, Asad Rehman, Robert Keller

North Texas GME Research Forum 2026

BACKGROUND Acute pancreatitis (AP) has become one of the leading gastrointestinal diagnoses resulting in inpatient hospitalization¹. AP is diagnosed by meeting two of three criteria: characteristic clinical presentation, biochemical evidence (elevated lipase or amylase levels), and imaging findings with pancreatic inflammation. Gallstones and heavy alcohol use account for most cases (40%–70% and 25%–35%, respectively). Hypertriglyceride induced AP (HTG-AP) accounts for only about 7-10% of AP cases³ and often tends to present in younger, male, obese, patients with a higher rate of diabetes¹. Below we present a unique case of a coinciding alcoholic and HTG - AP in an otherwise healthy …
