The Effects Of Capsaicin On Vascularization In Patients With Diabetes Mellitus: A Literature Review, Karen Hernandez, Leslie Guerrero, Myra Mudassar, Amanda L. Killeen

School of Podiatric Medicine Publications

Diabetes Mellitus (DM) is a metabolic disorder affecting 11.6% of the United States population and 43.95% of the population in the Rio Grande Valley of Texas. A common complication of diabetes mellitus is neuropathy, a type of nerve damage that affects as many as half of the people with this condition. Vascular factors and metabolic interactions are major influencers of the pathogenesis of diabetic neuropathy. This literature review evaluates the therapeutic role of capsaicin, a known component of capsicum pepper, commonly used as a treatment for neuropathic pain. However, several studies show that in addition to pain management, capsaicin counters …

Early Tissue Changes Linked To Diabetes: Insights From A Preclinical Model, Bryan Liu, Ramiro Cisneros, Estephania Garcia, Jimena Mora, Sumedha Guha, Evelin Rios, Krishna Prajapati, Danieli Rodrigues, Bhuvana Lakkasetter Chandrashekar, Claudia Biguetti

School of Podiatric Medicine - Student Research

Introduction and Hypothesis: The aim of this study is to compare soft tissue morphology and fibrosis pathology of different organs between diabetic and non-diabetic rats. Type 2 diabetes causes soft tissue remodeling in organ systems including heart, kidney, spleen, and pancreas. Fibrotic remodeling is a common pathological mechanism seen in diabetes-related organ dysfunction. By understanding fibrotic pathology in rats, it serves as a foundation to develop lower limb models applicable to podiatry. These systemic changes caused by diabetes may also play a role in lower limb changes such as diabetic ulcers and delayed wound healing.

Methodology: Male Lewis rats (6 …

Comparative Effectiveness Of Conservative Versus Early Surgical Treatments On Wound Healing Outcomes Of Diabetic Foot Ulcers: A Literature Review, Paul Tran, Yasim Zafar, Andrea Piña, Stephanie N. Campbell

School of Podiatric Medicine Publications

Diabetic foot ulcers (DFUs) are a severe complication of diabetes mellitus and the leading cause of lower extremity amputations worldwide. Peripheral neuropathy and peripheral arterial disease secondary to complications of diabetes mellitus may result in ulcers going unnoticed, increasing the risk of severe osteomyelitis, necrotizing infection, hospitalization, amputation, and sepsis. While conservative management of DFUs remains the first-line approach—emphasizing wound care, infection control, glycemic management, and offloading—there is growing debate about whether delaying simple surgical interventions worsens long-term outcomes. Surgeries such as tenotomy, digital amputation, and tendo-Achilles lengthening are minimally invasive options that can correct deformities, prevent recurrence, and promote …

New Vs. Reprocessed: A Scoping Review On Ilizarov Frame Reuse, James Hughes, Nicholas Obias, Dustin Prins, Amanda Killeen

School of Podiatric Medicine - Student Research

This review examines current literature regarding the viability of reused/reprocessed Ilizarov External Fixation (IEF) – with the end-goal of improving surgical options for complex limb pathologies in austere environments. We hypothesize this review will find no statistically significant difference between clinical outcomes of reused vs. new IEFs

IEF is an important but costly modality for complex limb pathologies, such as trauma, deformity, and nonunion (Chironga et al., 2023). Though effective, the cost of IEF is exacerbated by its single-use deployment (Chironga et al., 2023). A proposed cost-control measure is IEF reuse/reprocessing via (1) antiseptic pre-treatment, (2) structural stability assessment, (3) …

Lipid Discovery Enabled By Sequence Statistics And Machine Learning, Priya M. Christensen, Jonathan Martin, Aparna Uppuluri, Luke R. Joyce, Yahan Wei, Ziqiang Guan, Faruck Morcos, Kelli L. Palmer

School of Podiatric Medicine Publications

Bacterial membranes are complex and dynamic, arising from an array of evolutionary pressures. One enzyme that alters membrane compositions through covalent lipid modification is MprF. We recently identified that Streptococcus agalactiae MprF synthesizes lysyl-phosphatidylglycerol (Lys-PG) from anionic PG, and a novel cationic lipid, lysyl-glucosyldiacylglycerol (Lys-Glc-DAG), from neutral glycolipid Glc-DAG. This unexpected result prompted us to investigate whether Lys-Glc-DAG occurs in other MprF-containing bacteria, and whether other novel MprF products exist. Here, we studied protein sequence features determining MprF substrate specificity. First, pairwise analyses identified several streptococcal MprFs synthesizing LysGlc-DAG. Second, a restricted Boltzmann machine-guided approach led us to discover an …

Randomized Clinical Trial To Compare Cryopreserved And Lyopreserved Umbilical Cord Tissue To Treat Complex Diabetic Foot Wounds, Lawrence A. Lavery, Mehmet A. Suludere, Matthew J. Johnson, Amanda Killeen, Katherine M. Raspovic, Peter A. Crisologo, Arthur Tarricone

School of Podiatric Medicine Publications

To compare the incidence of infection, wound closure and time to wound closure in patients treated with cryopreserved (CPUT) and lyopreserved umbilical tissue (LPUT) in complex diabetic surgical wounds. This single-blinded 12-week randomized clinical trial compared cryopreserved and lyopreserved amniotic cord tissue to treat complex diabetic foot wounds. LPUT or CRAT was applied at baseline and again after four weeks. We enrolled subjects with UT2A-D and 3A-D wounds (depth to tendon, muscle, or bone with infection and/or PAD) and excluded subjects with ABI < 0.5 or TBI < 0.3, untreated osteomyelitis, and autoimmune diseases. We used a 3-D camera to evaluate wound area and volume. The mean baseline wound areas were 12.9 ± 10.7 cm2 for CPUT and 11.7 ± 7.0 cm2 for LPUT. The mean baseline wound volume was 7.5 ± 8.1 for CPUT and 9.2 ± 10.2 cm3 for LPUT. There was no difference between CPUT and LPUT in wound closure (36.8% vs 19.0%, P = .21) or infection (10.5% vs 4.8%, P = .60). There was no difference in mean …

School of Medicine Publications

Background

Emerging evidence suggests that endovascular thrombectomy is beneficial for treatment of childhood stroke, but the safety and effectiveness of endovascular thrombectomy has not been compared with best medical treatment. We aimed to prospectively analyse functional outcomes of endovascular thrombectomy versus best medical treatment in children with intracranial arterial occlusion stroke.

Methods

In this prospective registry study, 45 centres in 12 countries across Asia and Australia, Europe, North America, and South America reported functional outcomes for children aged between 28 days and 18 years presenting with arterial ischaemic stroke caused by a large-vessel or medium-vessel occlusion who received either endovascular …

Cryoablation Of Primary Breast Cancer Tumors Induces A Systemic Abscopal Effect Altering Time (Tumor Immune Microenvironment) In Distant Tumors, Flávia Sardela De Miranda, Dalia Martinez-Marin, Rachel L. Babcock, Maribel Castro, Geetha P. Boligala, Sonia Y. Khan, Kathryn L. Furr, Isabel Castro-Piedras, Nicholas Wagner, Dakota E. Robison

School of Medicine Publications

Introduction: Despite recent advances, triple-negative breast cancer (TNBC) patients remain at high risk for recurrence and metastasis, which creates the need for innovative therapeutic approaches to improve patient outcomes. Cryoablation is a promising, less invasive alternative to surgical resection, capable of inducing tumor necrosis via freeze/thaw cycles. Necrotic cell death results in increased inflammatory signals and release of preserved tumor antigens, which have the potential to boost the local and systemic anti-tumor immune response. Thus, compared to surgery, cryoablation enhances the activation of T cells leading to an improved abscopal effect, defined as the occurrence of a systemic response after …

Investing In Limb Preservation: A Case Report In Avoiding Bilateral Amputation In A Vasculopathy Patient, Nikita Gambhir, Heather V. Tran, Craig J. Verdin, Stephanie N. Campbell, Cyaandi Dove

School of Podiatric Medicine Publications

Limb salvage and prosthetics play vital roles in restoring function and mobility for patients with severe injuries or metabolic conditions. Limb salvage involves surgical techniques aimed at preserving a limb rather than resorting to amputation, while prosthetics provide artificial devices to replace lost limbs. Key considerations for limb salvage include restoring a functional foot, maintaining patient independence, minimizing hospitalizations, and avoiding bilateral lower limb amputations. Aggressive measures in wound care and surgery are needed for patients already at single-limb status with PAD and coronary artery disease (CAD).

Patients were categorized into low (0-5) and high (6-10) ASPECTS. Inverse probability of treatment weighting …

The Emerging Role Of Long Noncoding Rnas In Sorafenib Resistance Within Hepatocellular Carcinoma, Puneet Vij, Mohammad Shabir Hussain, Sanjaya Satapathy, Everardo Cobos, Manish Kumar Tripathi

School of Medicine Publications

Hepatocellular carcinoma (HCC), a liver cancer originating from hepatocytes, is a major health concern and among the most common malignancies worldwide. Sorafenib, approved by the U.S. F.D.A., is the primary first-line treatment for patients with advanced HCC. While the preferred first-line systemic regimen for HCC is immunotherapy with Atezolizumab plus bevacizumab or Tremelimumab-actl + durvalumab, Sorafenib is still an alternative recommended regimen. While some patients with advanced HCC may benefit from Sorafenib treatment, most eventually develop resistance, leading to poor prognosis. Long noncoding RNAs (lncRNAs) have been found to play a critical role in tumorigenesis and the development of HCC, …

The aim of this study is to describe the clinical characteristics, bacterial pathogens, and clinical outcomes in adults with foot infections due to intravenous drug use. Nine patients for whom the podiatric service was consulted for lower-extremity abscess secondary to intravenous drug use were included in this study. Most infections (66.7%) were located on the dorsal foot. Two of the abscesses (22.2%) resulted in amputation, with one toe amputation …

Management Of Group B Streptococcus Necrotizing Fasciitis Secondary To Puncture Wound In Diabetic Patient Using Xenograft* Therapy, Nikita V. Gambhir, Heather V. Tran, Stephanie N. Campbell

School of Podiatric Medicine Publications

Necrotizing soft tissue infection (NSTI) is a rapidly progressive skin and soft tissue infection that primarily affects deeper layers of adipose tissue, fascia and muscle. Once a patient becomes symptomatic, the disease typically progresses within hours. The standard treatment consists of broad-spectrum IV antibiotics, serial debridement and supportive care. However, long-term goals should include prevention of atherosclerotic disease, cardiovascular and cerebrovascular events, and ultimately, a reduction in mortality rates. Following debridement for NSTI, it is not uncommon for patients to require multiple surgeries and secondary wound healing given the extent of soft tissue loss.

Use Of A Borate-Based Bioactive Glass Matrix On Infected, Exposed Hardware, Stephanie N. Campbell, Cyaandi Dove, Connor V. Krolikowski

School of Podiatric Medicine Publications

A dreaded complication of implanting surgical hardware is a wound dehiscence resulting in hardware exposure; which places the wound at risk for infection and biofilm formation. Once established, biofilms are difficult to eradicate, with a high rate of recurrence even after surgical debridement. As such, there exists a significant need for novel technologies that can help us expedite healing in wounds with exposed hardware. Here we evaluate a borate-based bioactive glass matrix* in this challenging setting.

Effect Of A Potent Nitrogenous Bisphosphonate On Cell Viability In Diabetic Conditions: An In Vitro Study On Human Fibroblasts And Pre-Osteoblasts, Denae Cantu, Bryan Liu, Deborah Rocha Seixas, Claudia Biguetti

School of Podiatric Medicine - Student Research

Introduction Zoledronate (Zol) is a nitrogenous bisphosphonate (nBP) used to treat osteoporosis, bone metastases, and Charcot foot. Despite its efficacy in preventing fractures, concerns exist about its side effects on mesenchyme-origin cells and impaired wound healing. We hypothesize that Zol may impair the responses of human fibroblasts (hF) and pre-osteoblasts (MC3T3), potentially compromising tissue healing in the lower extremities of patients with diabetes.

Methodology: MC3T3 cells and hF were cultured in 96-well plates at a density of 2.5 x 10³ cells for 48 and 72 hours, respectively. Cells were subjected to normal glucose, high glucose, and high oxidative stress conditions …
