Research Colloquium

Background: The use of digital platforms to teach various subjects in the pre-clerkship curriculum is a fast-developing field, but their utility compared to traditional in-person didactics is unclear. Partly fueled by the recent demand for remote learning materials and ever-burgeoning access to artificial intelligence, the drive has been to develop materials to meet the demands of the digital age. Our goal is to evaluate the efficacy of the use of a digital atlas to improve learning outcomes in the field of neuroanatomy, namely developing skills in interpreting imaging studies featured on summative examinations. Literature has shown that the implementation of …

Pre-Hospital Stroke Time Intervals In The Rio Grande Valley, Kelsey Baker, Elio E. Garcia Sosa

Research Colloquium

Background and Introduction: Stroke continues to be a significant cause of mortality in the United States. Despite advancements in acute stroke treatments such as thrombolytic therapy and endovascular procedures, many patients remain unable to benefit from these interventions due to delays in receiving treatment. Healthcare professionals have made substantial efforts to improve 'door to needle' times, the interval between a patient's arrival at the hospital and the administration of thrombolytic therapy, yielding promising outcomes. However, a critical gap persists: the time interval from the onset of stroke symptoms to when patients actually present at a healthcare facility. This study aims …

Late Tamponade After Coronary Artery Bypass Grafting, Jian Garcia Cruz, Roy Kondapavuluru, Diana Othon Martinez, Julio Perez Rodriguez

Research Colloquium

Introduction: Pericardial effusion (PE) incidence can go up to 85% after cardiac procedures, however, not every pericardial effusion causes hemodynamic instability. Progression to Pericardial Tamponade (PT) occurs in 0.1 to 8.8% and may be either early (within 24 h post-cardiac surgery) or late (presenting within a week post-procedure). Both presentations may be attributed to anticoagulant use, inadequate mediastinal drainage, coagulopathy, post-pericardiotomy syndrome (recurrent pericardial effusion).

Patient presentation time might be misleading, as pericardial effusion’s clinical symptoms are varied, ranging from asymptomatic, to shortness of breath, chest pain or discomfort, hypotension, tachycardia, or other non-specific symptoms like cough, fever, and malaise. …

Multiple Intracardiac Thrombi In A Patient With Ischemic Cardiomyopathy, Jian Garcia Cruz, Julio Perez Rodriguez

Research Colloquium

Introduction: Ischemic cardiomyopathy is defined by the American Heart Association (AHA) as cardiomyopathy caused by ischemic heart disease. The most common complication of ischemic cardiomyopathy is systolic congestive heart failure. Heart failure patients are in a hypercoagulable state that predisposes them to develop intracardiac thrombus. The incidence of LV thrombus in patients with dilated cardiomyopathy and sinus rhythm is 13% with the clot in the left atrial appendage in 68% of these cases. The thrombus formation results from impaired blood flow within the 4 chambers of the heart and can present as a life-threatening complication of end stage heart failure. …

Cardiac Tamponade Secondary To Purulent Pericarditis With Mrsa, Jian Garcia Cruz, Julio Perez Rodriguez

Research Colloquium

Introduction: Methicillin resistant Staphylococcus aureus (MRSA) is a nosocomial pathogen that causes severe morbidity and mortality worldwide. MRSA pericarditis is a rare life-threatening condition that can cause purulent pericarditis with only 7 cases having been reported so far. Several reasons why a patient may develop MRSA pericarditis are healthcare-associated infection, weakened immune system, invasive procedures and spread from other infections. Although not typically associated with tamponade, if MRSA were to cause an infection in the pericardial space, it could potentially lead to inflammation and fluid accumulation, resulting in tamponade. We present a case of a woman that developed tamponade secondary …

Unveiling The Impact Of Phosphate On Skeletal Muscle Dysfunction In Chronic Kidney Disease, Hiram Garcia, Sowmya Duddu, Erik Hinojosa, Model Zerfu, Nathaniel L. Alvarez, Mohammad Razzaque, Alex Zuo

Research Colloquium

Background: Chronic Kidney Disease (CKD) is characterized by progressive decline in renal function that ultimately culminates in the inability of the kidneys to effectively maintain homeostasis. The kidneys are a key regulator of phosphate, with other organs assisting in regulation including the skeletal system. In CKD, reduced kidney function leads to hyperphosphatemia. While its impact on the skeletal system is moderately studied, its effects on skeletal muscle are less reviewed. In our literature review, we aim to describe the effects of phosphate in the context of patients who have CKD while providing clinical context for this deserving population. We describe …

Phytocannabinoids In Combination: Chronic Pain, Emmanuel Franco, Jose Rios, Laura Valdez, Andrew Tsin, Khalid Benamar

Research Colloquium

Background: Chronic pain, one of the most common reasons adults seek medical care, has been linked to restrictions in mobility and daily activities, dependence on opioids, anxiety, depression, sleep deprivation, and an overall reduced quality of life. Unfortunately, the current treatment options for chronic pain are limited, often ineffective, and have associated side effects. Better outcomes can be achieved by developing new and improved therapeutics or more immediately by identifying favorable drugs that are already available or emerging as potential new analgesics. There is a growing interest in the use of opioid-sparing analgesics, in particular medicinal cannabis, for pain management. …

Research Colloquium

Background: Established literature suggests a strong relationship between exposure to air contaminants and physical health. Similarly, numerous studies have demonstrated the effects of water pollution on public health. Texas denizens are often victims of poor air and water quality, yet there are scant studies that have integrated evidence of health tolls caused by air and water pollution across the state. In this study, we assessed the relationship between particulate matter

Methods: The study used data from the 2018 Medicare and Medicaid report which displayed chronic health conditions across all counties in Texas. Additionally, the study also includes collected data on …

Unveiling The Neurological Aftermath: Pres After Cardiac Arrest, Oyinlola O. Fasehun, Jessica Daza, Sriharsha Koneru, Victor Tran, Eunbee Cho, Fatimah Bello

Research Colloquium

Background: Posterior Reversible Encephalopathy Syndrome (PRES), also known as ‘Reversible Posterior Leukoencephalopathy Syndrome (RPLS)’, is a clinical radiographic syndrome originally described by Hinchey et al in 1996. PRES has been significantly underdiagnosed due to difficulty in confirmation. As such, there is currently no epidemiological data regarding its incidence, but it has been diagnosed in all age groups with a preponderance in females. A variety of medical conditions have been implicated as causes of PRES, including severe hypertension, immunosuppressive therapy, sepsis, renal diseases and autoimmune disorders. The mechanism of PRES is thought to be related to disordered cerebral autoregulation and endothelial …

Cognitive Impairment And Hearing Loss In The Rio Grande Valley: A Retrospective Study Of Alzheimer's, Dementia, And Mild Cognitive Impairment, Victoria Elizondo, Antoinette Burrell, Chantal Uzoma, Desiree Brewer, Naya Williams, Erica Burrell-Walker, Kelsey Baker

Research Colloquium

Background: Millions of US adults experience underrecognized hearing loss, despite effective treatments. Interestingly, hearing loss has been suggested to be further exacerbated in populations of Alzheimer’s Disease. It is hypothesized that structural and functional features of auditory brain organization, which make it vulnerable to neurodegeneration, may heighten susceptibility to hearing loss, although it is unclear how ethnicity impacts its epidemiology. Here, we sought to address this gap by exploring the association between self-reported hearing loss and cognitive decline in Hispanic and non-Hispanic patients across the Rio Grande Valley (RGV).

Methods: We conducted a retrospective review of the UTHealth RGV electronic …

Pseudogout: A Rare Cause Of Pseudoseptic Arthritis - A Case Report, Yareli Durazo, Corey Haines, Elimar Gonzalez, Brandon Cantazaro, Michael Sander

Research Colloquium

Introduction: Pseudoseptic arthritis is the umbrella term designated to various mimics when they present with clinical stigmata indicative of septic arthritis. The underlying causes of these mimics can vary, depending on whether they are associated with autoimmune inflammatory arthritis or crystalline-associated inflammatory arthritis such as gout and calcium pyrophosphate deposition disease (CPPD). In clinical practice, pseudoseptic arthritis can be difficult to differentiate from infectious arthritis, leading to frequent misdiagnosis. However, key differences will exist in the joint aspirate. With septic arthritis, the synovial fluid cultures are positive. However, with pseudoseptic arthritis, the synovial fluid may appear purulent but is sterile. …

Prognostic Utility Of The Lactate/Pyruvate Ratio For Mortality In Patients With Sepsis: An Observational Study, Edgar G. Dorsey-Trevino, Olga G. Cantu-Rodriguez, Jose A. Hawing-Zarate, Grecia A. Gonzalez-Cantu, David Gomez-Almaguer, Cesar H. Gutierrez-Aguirre

Research Colloquium

Introduction: Measurement of serum lactate remains pivotal in sepsis evaluation as it is closely related to tissue hypoxia and mortality.^{1, 2} Serum lactate, however, can be elevated due to a myriad of reasons beyond hypoperfusion.³ A proposed alternative to control for serum lactate’s inherent variability is to measure pyruvate concomitantly to calculate the lactate/pyruvate (L/P) ratio.^{4, 5} As pyruvate transforms into lactate in anaerobic conditions, its value decreases in serum, increasing the L/P ratio, hence indicating an actual tissue-perfusion mismatch.⁶ Despite its clinical utility, there is a paucity of evidence evaluating the role of the L/P …

Pernicious Anemia Presenting With Pancytopenia And Hemolysis: A Case Report From South Texas, Yareli Durazo, Victor Tran, Sriharsha Koneru, Andres Suarez Parraga

Research Colloquium

Introduction: Pancytopenia is a commonly encountered hematologic entity with varying clinical presentations. It results from various disease processes ranging from simple to life-threatening. The most common cause of pancytopenia is megaloblastic anemia, and the most common causes of megaloblastic anemia are deficiencies of vitamin B9 or B12. Thus, folate and B12 deficiency should be high in the differential diagnosis when patients present with pancytopenia. Hemolytic anemia, anemia due to the shortened survival of circulating erythrocytes, often represents a more difficult diagnostic challenge for the clinician. While recognition of ongoing hemolysis is usually rapid and relatively simple, establishing the cause can …

Potential Involvement Of Srb1 In Type 1 Diabetes Associated Dyslipidemia: Characterizing Srb1 Antisense, Sowmya Duddu, Masami Shimizu-Albergine, Karin E. Bornfedlt

Research Colloquium

Background: One of the main complications of type 1 diabetes is cardiovascular disease associated with dyslipidemia, characterized by abnormally high levels of triglyceride-rich lipoproteins in the bloodstream. This imbalance could eventually lead to complications such as atherosclerosis. Liver Scavenger Receptor Class B Type 1 (SRB1) is currently being investigated for its role in type 1 diabetes induced dyslipidemia. We aim to characterize the effects of using a liver specific SRB1 antisense (GalNAc-SRB1 ASO) in non-diabetic and diabetic mice. We hypothesize that triglyceride and cholesterol levels will increase to a greater extent in diabetic mice injected with GalNAc-SRB1 ASO than in …
