What's Going On With The Spine? Evaluation Of Alternative Sensorimotor Degeneration Post-Stroke, Sravani Mannuru, Sarvani Uppati, Kelsey Baker

MEDI 9331 Scholarly Activities Clinical Years

Stroke is a leading cause of long-term disability in the United States. Previous research has shown a strong correlation between damage to the corticospinal tract (CST) and motor deficits in post-stroke patients. However, recent research suggests that other sensorimotor pathways (rubrospinal tract, medial reticulospinal tract) are damaged after stroke and may also contribute to motor dysfunction. Here, we will review current research suggesting that alternate sensorimotor pathways are involved in post-stroke motor dysfunction and outline possible avenues for future research.

Purpose: Indocyanine Green (ICG) near-infrared (NIR) fluorescence angiography is used in assessing testicular perfusion after reduction of testicular torsion to assess tissue viability.

Introduction: Determination of viability of a testicle after reduction of a testicular torsion has been performed by numerous methods including visual assessment, Doppler ultrasound, and cutting the testicular capsule. Each of these has limitations, are not always reproducible, and may involve damage to the testicle and confusion of capsular blood flow for internal perfusion. A possible alternative to these methods is the use of ICG-NIR fluorescence angiography. ICG was FDA-approved in 1959 and has been …

Objective: To determine whether the punctuated administration of low-dose rituximab, temporally linked to B-cell hyperrepopulation (defined when the return of CD19+ B cells approximates 40%-50% of baseline levels as measured before alemtuzumab treatment inception), can mitigate alemtuzumab-associated secondary autoimmunity.

Methods: In this hypothesis-driven pilot study, 10 patients received low-dose rituximab (50-150 mg/m2), a chimeric anti-CD20 monoclonal antibody, after either their first or second cycles of alemtuzumab. These patients were then routinely assessed for the development of autoimmune disorders and safety signals related to the use of dual monoclonal antibody therapy.

Results: Five patients received at least 1 IV infusion of …

Long Non-Coding Rna (Lncrna) As A New Biomarker For Hepatocellular Carcinoma (Hcc) Progression And Drug Resistance, Areeb Masood, Sanjaya Satapathy, Manish Tripathi

MEDI 9331 Scholarly Activities Clinical Years

Hepatocellular carcinoma (HCC) is a primary malignant liver tumor that commonly occurs as a progression of chronic liver inflammation due to long-standing viral hepatitis infection, toxins, metabolic conditions, and congenital disorders. In 2018, HCC was the 4th leading cause of cancer-related deaths worldwide, accounting for approximately 780,000 deaths in total.

HCC’s prognosis is directly correlated with early detection. Unfortunately, HCC has an asymptomatic pattern of growth in the early stages of the disease which makes early detection challenging. When HCC progresses to advanced stages, it leaves clinicians with limited therapeutic and curative options, leading to high rates of morbidity and …

Telehealth Care And Its Role In Undergraduate Medical Education In The Covid-19 Era., Peter J. Gonzalez, Dustin J. Paul

MEDI 9331 Scholarly Activities Clinical Years

Background

On March 17, 2020, the American Association of Medical Colleges issued a statement which “strongly supports medical schools pausing all student clinical rotations, effective immediately, until at least March 31.” The University of Texas Rio Grande Valley School of Medicine immediately withdrew third- and fourth-year students from clinical rotation sites, and developed alternative, online-based clerkship curricula to complete for the remainder of the academic year. The COVID-19 pandemic has brought about many challenges to Undergraduate Medical Education, and has deprived upper-level students of foundational, in-person, clinical experiences. The UTRGV School of Medicine Department of Neurology is among the first …

Purpose: Coronavirus disease 2019 (COVID-19) has affected millions of people all over the world with worse proven outcomes in those with certain comorbid conditions, such as diabetes, cardiovascular disease, and pulmonary complications. The Rio Grande Valley located in South Texas with a largely Hispanic population has been hit especially hard during this pandemic with over 3,200 virus-related deaths. This region’s high population of diabetic and obese patients is likely correlated with the especially high mortality rate. While it is understood the impact that obesity has on worsening health outcomes, further research is needed to better understand whether more adverse COVID-19 …


Progressive Lowering Of Transverse Mastectomy Scars Onto The Inframammary Fold: A Novel Technique To Simultaneously Improve Cosmesis While Performing Implant-Based Breast Reconstruction, Annalisa Lopez Oct 2020

Progressive Lowering Of Transverse Mastectomy Scars Onto The Inframammary Fold: A Novel Technique To Simultaneously Improve Cosmesis While Performing Implant-Based Breast Reconstruction, Annalisa Lopez

MEDI 9331 Scholarly Activities Clinical Years

The post-reconstruction appearance of mastectomy scars is a contributing factor that affects how patients perceive themselves after breast reconstruction.1 Patients that undergo a skin-sparing mastectomy (SSM) may often have a periareolar incision which can leave an unappealing transverse scar. Regardless of whether reconstruction is performed in a delayed or immediate fashion, the transverse mastectomy scar itself commonly lies in the center of the breast near the reconstructed nipple-areolar complex, causing psychological trauma and continued patient dissatisfaction.2 This also may lead to post-reconstruction multiple mastectomy scar revisions. This research aims to describe a novel technique to reliably avoid the presence of …

Muslim renal transplant recipients often ask their physicians if performing certain lifestyles or religious obligations may be harmful to their health. Permissibility as advised by an expert Muslim physician is considered as being religiously accepted. A cross-sectional, survey-based study was conducted enquiring what nephrologists would advise their transplant recipients to do, about some lifestyles and religious duties. Fifty-eight nephrologists responded to the survey. Of these, 77% routinely follow-up post-transplant patients; 34% were from Saudi Arabia, 18% from the USA, and 20% from Pakistan. Fifty-four percent of the respondents would let patients with stable graft function fast during Ramadan, while 20% …

Here, in Part II of a duology on the characterization and potential treatment for COVID-19, we characterize the application of an innovative treatment regimen for the prevention of the transition from mild to severe COVID-19, as well as detail an intensive immunotherapy intervention hypothesis. We propose as a putative randomized controlled trial that high-dose methotrexate with leucovorin (HDMTX-LR) rescue can abolish 'PANIC', thereby 'left-shifting' severe COVID-19 patients to the group majority of those infected with SARS-CoV-2, who are designated as having mild, even asymptomatic, disease. HDMTX-LR is endowed with broadly pleiotropic properties and is a repurposed, generic, inexpensive, and widely …

Severe acute respiratory syndrome coronavirus 2 has spread rapidly around the globe. However, despite its high pathogenicity and transmissibility, the severity of the associated disease, COVID-19, varies widely. While the prognosis is favorable in most patients, critical illness, manifested by respiratory distress, thromboembolism, shock, and multi-organ failure, has been reported in about 5% of cases. Several studies have associated poor COVID-19 outcomes with the exhaustion of natural killer cells and cytotoxic T cells, lymphopenia, and elevated serum levels of D-dimer. In this article, we propose a common pathophysiological denominator for these negative prognostic markers, endogenous, angiotensin II toxicity. We hypothesize …

Diabetic retinopathy (DR) is a complication of diabetes due to damage of blood vessels in the retina. Aside from being a major cause of blindness in the world, DR also has a significant impact on quality of life. Although there are methods to delay the progression of DR, there are no existing therapeutic regimens for early intervention. Thus, it is critical to develop cost-effective therapies towards preventing DR development.

School of Medicine Publications and Presentations

To the Editor Yeo et al1 evaluated factors associated with American Board of Surgery (ABS) examination pass rates in a cohort of categorical surgical residents from the internship (2007) to eligibility/certification. They found that first-time ABS pass rate was associated with nonmodifiable factors, such as nonwhite race/ethnicity, sex (women), and having children.1 Additionally, Hispanic residents were less likely to attempt the ABS examinations at all. We must place these findings in the context of diversity in surgery, or rather, the lack thereof. The cohort included only 55 Hispanic residents, most of whom did pass the ABS examinations (n …
