The Effect Of Limb Salvage Efforts In Different Age Groups: Relationships Between Major And Minor Amputations, Wenye Song, Javier La Fontaine, Naohiro Shibuya, John Prochaska, Daniel C. Jupiter

School of Podiatric Medicine Publications

“Limb salvage” efforts, such as performing minor amputations before infections spread proximally from the foot to decrease major lower extremity amputation, are an important part of healthcare today. It is unclear whether these efforts are preventing the number of major amputations and improving patients’ quality of life and the cost-effectiveness of the U.S. healthcare system. Rates of non-traumatic lower extremity amputation (NLEA) among patients with diabetes decreased in the early 2000s but rebounded in the 2010s. We analyzed the proportion of major amputations and differences in amputation rates between age groups in Texas. Patient data was extracted from the Texas …

A Proposed Addition To The Modified Wells Criteria: Exploring Thrombosis In The E-World, Nidhin John, Amanda Kileen

School of Podiatric Medicine - Student Research

The advancement of technology and over-reliance on electronics have led to "e-thrombosis." This review investigates the link between prolonged sedentary behavior due to extensive electronic use and the risk of venous thromboembolism (VTE) and deep vein thrombosis (DVT). The term "e-thrombosis" was introduced in 2003 by Beasley et al., highlighting the risk of immobility associated with electronics. E-thrombosis is particularly relevant post-COVID-19, with increased remote working and online learning. This review evaluates recent studies to determine if e-thrombosis should be considered in updated screening tools like the Wells Score.

A systematic literature review was conducted using PubMed, Direct Science, and …

School of Podiatric Medicine Publications

Highlights

• Peripheral artery disease (PAD) is a multi-level disease.

• PAD diffusely impairs the performance of leg muscles.

• PAD causes similar irregularities in gait biomechanics regardless of where claudication pain is located in the leg.

Abstract

Background

The most common symptom of peripheral artery disease (PAD) is intermittent claudication that involves the calf, thigh, and/or buttock muscles. How the specific location of this leg pain is related to altered gait, however, is unknown.

Objectives

We hypothesized that because the location of claudication symptoms uniquely affects different leg muscle groups in people with PAD, this would produce distinctive walking patterns.

Methods

Lamina Cribrosa Insertions Into The Sclera Are Sparser, Narrower, And More Slanted In The Anterior Lamina, Fengting Ji, Mohammad R. Islam, Bingrui Wang, Yi Hua, Ian A. Sigal

Mechanical Engineering Faculty Publications

Purpose: The lamina cribrosa (LC) depends on the sclera for support. The support must be provided through the LC insertions. Although a continuous insertion over the whole LC periphery is often assumed, LC insertions are actually discrete locations where LC collagenous beams meet the sclera. We hypothesized that LC insertions vary in number, size, and shape by quadrant and depth.

Methods: Coronal cryosections through the full LCs from six healthy monkey eyes were imaged using instant polarized light microscopy. The images were registered into a stack, on which we manually marked LC insertion outlines, nothing their position in-depth and quadrant …

Unraveling Sorafenib Resistance In Hepatocellular Carcinoma: Exploring Key Facets, Dennis Kwabiah, Kyle Doxtater, Yamile Abuchard, Sophia Leslie, Ricardo Pequeno Bracho, Shaibir Hussain, Manish K. Tripathi

Research Symposium

Hepatocellular carcinoma (HCC) stands as the prevalent form of primary liver cancer worldwide, diagnosing over half a million new cases annually. Surgical interventions like hepatectomy and liver transplantation offer a potential cure for early-stage HCC. However, the prognosis for advanced stages remains grim due to drug resistance, particularly with high refractoriness rates. Sorafenib, a tyrosine kinase inhibitor, is an approved treatment for advanced HCC. Despite its use, the overall survival extension for these patients remains limited due to the drug's ineffectiveness, and the mechanism behind advanced HCC's resistance to sorafenib remains elusive. TCGA analysis of HCC patient cohorts reveals elevated …

Too Yellow: An Idiopathic Case Of Autoimmune Hemolytic Anemia, Shreel Patel, Kashif Ali, Donnel Dockery-Joseph, Eunbee Cho, Sriharsha Koneru, Taha Al Hassan, Aramide Tijani, Elimar Gonzalez Morales

Research Symposium

Background: Autoimmune hemolytic anemia is caused by autoantibodies that react with self red blood cells and cause them to be destroyed. Warm AIHA, due to antibodies that are active at body temperature, is the most common type of the AIHA. It is mostly caused by the underlying disease like infections, autoimmune disorders, lymphoproliferative disorders, immunodeficiency or physiologic state like pregnancy. Rarely it happens that there is no underlying cause. Therefore, here we present a case of idiopathic autoimmune hemolytic anemia without any underlying cause.

Case Discussion: A 77 year old lady with known history of the diabetes mellitus type 2, …

Spontaneous Tumor Lysis Syndrome In A Patient With Recent Diagnosis Of Multiple Myeloma — An Unusual Presentation, Taha Al Hassan, Olga G. Cantu-Rodriguez, Eunbee Cho, Edgar G. Dorsey Trevino

Research Symposium

Background: Tumor lysis syndrome (TLS) is an oncologic emergency that surfaces as a constellation of metabolic imbalances due to the rapid destruction of cancer cells and subsequent dissemination of their contents. However, a markedly rare subtype of TLS, known as spontaneous TLS (STLS), occurs without an evident trigger, such as cytotoxic therapy, and carries a similar mortality risk. It is paramount to recognize high-risk cases early and implement therapeutic measures to prevent complications of STLS.

Case Presentation: We present the case of a 74-year-old gentleman with a recent diagnosis of Kappa-restricted multiple myeloma who presented with worsening weakness, tremors, ataxia, …

Influence Of Neurotoxin Load On Parkinson’S Disease Pathophysiology, Abhishekh Pokhrel, Daniel Salinas, Nawaz Hack, Kelsey Potter-Baker

Research Symposium

Background: Parkinson’s disease (PD) is a debilitating neurodegenerative disorder impacting movement, mood, and cognition. Among those affected, veterans, due to their occupational exposures, are particularly susceptible, contributing to over 110,000 PD cases in the United States. Studies have largely attributed this increased prevalence among veterans to environmental neurotoxins such as Agent Orange, MPTP, and 6-OHDA. However, it remains unclear how neurotoxin exposure load influences biological mechanisms in PD. This study aims to elucidate the influence of neurotoxin load on PD-associated molecular changes, neuroplasticity, neurodegeneration, and cognitive and motor function within a clinical population of the Rio Grande Valley region …
