ABSTRACT

Reassessing Hourly Neurological Assessments: A Quality Improvement Initiative

Haley Lynne Johnson, BSN, RN

Background: Stroke and brain injuries remain among the leading causes of mortality in the United States, accounting for 162,890 deaths in 2021 (Centers for Disease Control and Prevention [CDC], 2021). Although frequent neurological assessments are essential for monitoring patient status, limited evidence supports the prolonged use of hourly neuro-checks (LaBuzetta et al., 2022). Excessive neuro-check frequency has been linked to sleep deprivation, an increased risk of delirium, and inefficient resource utilization (Kishore et al., 2021).

Purpose: This project aimed to assess the impact of …

Despite the efficacy of approved severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in preventing severe disease and death, breakthrough infections continue to occur in vaccinated individuals, contributing to further viral mutation and spread. These limitations may be attributable to the poor induction of mucosal immunity by parenteral vaccination. Mucosal adjuvants, such as T-vant, can enhance vaccine-induced immune responses through the generation of antigen-specific antibodies and T cells in the respiratory tract. In this study, we evaluated the protective efficacy of adjuvanted SARS-CoV-2 receptor binding domain (RBD) subunit vaccines administered by homologous and heterologous routes. Immunized mice were challenged with …


A New Interpolated Pseudodifferential Preconditioner For The Helmholtz Equation In Heterogeneous Media, Sebastian Acosta, Tahsin Khajah, Benjamin Palacios Jan 2025

A New Interpolated Pseudodifferential Preconditioner For The Helmholtz Equation In Heterogeneous Media, Sebastian Acosta, Tahsin Khajah, Benjamin Palacios

Faculty, Staff and Students Publications

This paper introduces a new pseudodifferential preconditioner for the Helmholtz equation in variable media with absorption. The pseudodifferential operator is associated with the multiplicative inverse to the symbol of the Helmholtz operator. This approach is well suited for the intermediate and high-frequency regimes. The main novel idea for the fast evaluation of the preconditioner is to interpolate its symbol, not as a function of the (high-dimensional) phase-space variables, but as a function of the wave speed itself. Since the wave speed is a real-valued function, this approach allows us to interpolate in a univariate setting even when the original problem …

Faculty, Staff and Students Publications

Introduction: The intestine has molecular and functional diversity across the proximal-distal and the crypt-villus axes, so it is imperative to determine the common and compartment-specific molecular actions of vitamin D. However, very little work on vitamin D mediated gene regulation has been done in normal human intestine. Here, we examined the impact of 1,25-dihydroxyvitamin D (1,25(OH)2D3) on cultures of human intestinal epithelium derived from duodenum (Dd) and distal colon (Co) biopsies of 6 subjects per tissue.

Methods: Human enteroids and colonoids were cultured for 3 days to promote a stem cell phenotype (undifferentiated, Un) or to induce differentiation (Diff) and …

Faculty, Staff and Students Publications

INTRODUCTION: The oncogene MDM2 has garnered attention not only for its role in cancer as a negative regulator of the tumor suppressor p53 but also for its p53-independent oncogenic activities. MDM2 also involves metabolic reprogramming, such as serine metabolism, respiration, mitochondrial functions, the folate cycle, and redox balance. Traditional MDM2 inhibitors blocking the protein-protein binding between MDM2 and p53 have shown limited clinical success in various stages of clinical trials, most likely due to low efficacy, drug toxicity, and drug resistance, highlighting the need for a novel, p53-independent strategy to inhibit MDM2. The present study investigated the antitumor effects of …

Innovative Biomechanical And Engineering-Based Assessments Of Hip Mechanics In Individuals With Hip-Related Pain, Holly M. Stanze Jan 2025

Innovative Biomechanical And Engineering-Based Assessments Of Hip Mechanics In Individuals With Hip-Related Pain, Holly M. Stanze

Theses and Dissertations--Kinesiology and Health Promotion

Individuals with hip-related pain exhibit altered movement patterns, and worse fear of movement (kinesiophobia), compared to asymptomatic controls. Exacerbation of hip pain during movement and the role of hip symptom duration may help further our understanding of specific movement patterns that are associated with hip-related pain. A better understanding of the potential connections between hip-related symptom duration, kinesiophobia, hip pain during movement, and lower limb mechanics in those with hip-related pain may allow for more efficient referrals to clinicians and lead to more effective rehabilitation. In addition, the impact of hip-related pain on intra-articular hip loading patterns is not well …

Advancing Narcolepsy Advocacy: Bridging Patient Narratives And Systemic Change, Ahmed Salem Bahammam, Lindsay Jesteadt, Hamza Dhafar, Amir Sharafkhaneh

Faculty, Staff and Students Publications

We introduce the Stigma-to-Structure Advocacy Framework, a novel, evidence-based model designed to transform narcolepsy advocacy by systematically bridging patient narratives with structural change. Narcolepsy remains a profoundly underdiagnosed and misunderstood neurological disorder, with persistent diagnostic delays and pervasive cultural stigma undermining patient well-being and access to care. Despite recent progress in awareness and support, advocacy efforts remain fragmented and insufficiently integrated with health policy, particularly in low- and middle-income countries. This perspective advances a strategic evolution of narcolepsy advocacy through the Stigma-to-Structure Advocacy Framework, which is anchored in three pillars: narrative-driven awareness, clinical system integration, and policy activation. Drawing on …

Small Molecule Screening Identifies Hsp90 As A Modifier Of Rna Foci In Myotonic Dystrophy Type 1, Sara J Johnson, Hannah L Johnson, Reid T Powell, Clifford Stephan, Fabio Stossi, Thomas A Cooper

Faculty, Staff and Students Publications

Myotonic dystrophy type 1 (DM1) is a multisystemic disorder caused by a CTG triplet repeat expansion within the 3' untranslated region of the DMPK gene. Expression of the expanded allele generates RNA containing long tracts of CUG repeats (CUGexp RNA) that form hairpin structures and accumulate in nuclear RNA foci; however, the factors that control DMPK expression and the formation of CUGexp RNA foci remain largely unknown. We performed an unbiased small molecule screen in an immortalized human DM1 skeletal muscle myoblast cell line and identified HSP90 as a modifier of endogenous RNA foci. Small molecule inhibition of HSP90 leads …

Faculty, Staff and Student Publications

A great deal of attention is being paid to strategies seeking to uncover the biology of the four-stranded nucleic acid structure G-quadruplex (G4) via their stabilization in cells with G4-specific ligands. The conventional definition of chemical biology implies that a complete assessment of G4 biology can only be achieved by implementing a complementary approach involving the destabilization of cellular G4s by ad hoc molecular effectors. We report here on an unprecedented comparison of the cellular consequences of G4 chemical stabilization by pyridostatin (PDS) and destabilization by phenylpyrrolocytosine (PhpC) at both transcriptome- and proteome-wide scales in patient-derived primary human astrocytes.

Molecular Imaging Of Triple-Negative Breast Cancer: Characterization And Modulation Of The Tumor Microenvironment, Shannon E. Lynch Jan 2025

Molecular Imaging Of Triple-Negative Breast Cancer: Characterization And Modulation Of The Tumor Microenvironment, Shannon E. Lynch

All ETDs from UAB

Triple-negative breast cancer (TNBC) is an aggressive, heterogeneous subset of breast cancer which currently has no targeted therapies available due to lack of molecular therapeutic targets. Importantly, various radiopharmaceuticals can be imaged via positron emission tomography (PET) to quantify cellular and molecular features of the tumor microenvironment including glucose metabolism, receptor status, and immune activation. Somatostatin receptor subtype 2 (SSTR2) is G-protein coupled receptor overexpressed in neuroendocrine tumors (NETs) which can be imaged and targeted for theranostics via FDA-approved radiotherapy. SSTR2 expression is increased in hormone positive breast cancer but is expressed at low or variable levels in TNBC. However, …

Evaluating Multiparametric Imaging Biomarkers For Guiding Targeted Therapies In Her2+ Breast Cancer, Ameer Mansur

All ETDs from UAB

Human epidermal growth factor receptor 2 positive (HER2+) breast cancer is a biologically diverse disease, in which intratumoral heterogeneity plays a significant role in tumor progression. Advanced medical imaging and image processing techniques offer the potential to noninvasively characterize the underlying intratumoral biology. Capturing these complex changes can allow for assessing therapeutic response and eventually guiding personalized therapeutic strategies. This work evaluates single and multiparametric imaging biomarkers to characterize tumor biology, identify treatment-induced changes, and predict response to targeted therapies. First, the utility of 3’-Deoxy-3’-[18F]Fluorothymidine positron emission tomography ([18F]FLT-PET) was assessed as a biomarker of proliferation for monitoring response to …

Successful Treatment Of An Atypical Presentation Of Disseminated Retroperitoneal Seminoma: A Case Report, Mahmoud Abd-El-Hafez, Kylie Johnson, Joe Cates, Alosh Madala

HCA Healthcare Journal of Medicine

Background

Testicular seminoma is the most common malignant tumor of the testis. It occurs at a rate of 5 per 100 000 men, primarily between the ages of 15 to 34. While seminomas typically occur in the testis, other primary sites include the mediastinum, the retroperitoneum, or other extra-gonadal sites. Due to the curable nature of the malignancy (5-year survival rate > 95%), detection at early stages of the disease is key. This case presentation explores the delayed diagnosis and treatments of an atypical presentation of disseminated seminoma.
