Department of Neurosurgery Faculty Papers

Wound closure is an integral part of every spinal procedure. Effective and secure wound closure is paramount in the prevention of infection, wound dehiscence and the preservation of cosmesis. Barbed suture technologies such as STRATAFIX™ Symmetric have been studied and are used in a variety of specialties, including obstetrics and orthopedic surgery, but is underutilized in neurosurgery. This study aims to assess the time and rate of closure using STRATAFIX™ Symmetric technology for fascial closure and compare this method to the more traditionally used method of fascial closure using braided absorbable sutures below the epidermis. 20 patients were recruited for …

Immunoregulatory Properties Of Immune Cells That Associate With The Lens Capsule Surface During Acute And Resolution Phases Of Experimental Autoimmune Uveitis, Phuong M. Le, Mary J. Mattapallil, Rachel R. Caspi, Mary Ann Stepp, A. Sue Menko

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Inflammation in the eye is tightly regulated to prevent vision impairment and irreversible blindness. Emerging evidence shows that immune cells are specifically recruited to the lens capsule in response to autoimmune uveitis, yet the potential that they have a role in regulating this inflammatory disease remained unexplored. Here, an immunolocalization approach combined with high-resolution confocal microscopy was used to investigate whether the immune cells that become stably associated with the lens capsule in the eyes of C57BL/6J mice with experimental autoimmune uveitis (EAU) have an immunoregulatory phenotype. These studies revealed that during the acute phase of uveitis, at day 18 …

Synergistic Activation By Glass And Pointed Promotes Neuronal Identity In The Drosophila Eye Disc, Hongsu Wang, Komal Kumar Bollepogu Raja, Kelvin Yeung, Carolyn A Morrison, Antonia Terrizzano, Alireza Khodadadi-Jamayran, Phoenix Chen, Ashley Jordan, Cornelia Fritsch, Simon G Sprecher, Graeme Mardon, Jessica E Treisman

The integration of extrinsic signaling with cell-intrinsic transcription factors can direct progenitor cells to differentiate into distinct cell fates. In the developing Drosophila eye, differentiation of photoreceptors R1-R7 requires EGFR signaling mediated by the transcription factor Pointed, and our single-cell RNA-Seq analysis shows that the same photoreceptors require the eye-specific transcription factor Glass. We find that ectopic expression of Glass and activation of EGFR signaling synergistically induce neuronal gene expression in the wing disc in a Pointed-dependent manner. Targeted DamID reveals that Glass and Pointed share many binding sites in the genome of developing photoreceptors. Comparison with transcriptomic data shows …

Companion Dogs And Depression, Anxiety, And Posttraumatic Stress Disorder In Adult Icu Survivors: A Scoping Review, Lindsey Nelson, Sue Lasiter, Amanda Emerson

People and Animals: The International Journal of Research and Practice

Intensive care unit (ICU) survivors are at risk for developing persistent psychological sequelae that have been linked to decreased quality of life and increased mortality after hospital discharge. Standardized evidence-based treatments are lacking, mainly focus on physical rather than psychological recovery, and often occur in formal settings. Benefits of human– companion dog relationships have not been explored in the ICU survivor population before. Thus, the purposes of our review were to summarize the literature focused on the influence of companion dogs on depression, anxiety, and posttraumatic stress disorder (PTSD); identify what is known about the potential role companion dogs play …

Long-Range White Matter Fibres And Post-Stroke Verbal And Non-Verbal Cognition, Rebecca W. Roth, Deena Schwen Blackett, Ezequiel Gleichgerrcht, Janina Wilmskoetter, Chris Rorden, Roger Newman-Norlund, Souvik Sen, Julius Fridriksson Ph.D., Natalie Busby, Leonardo Bonilha

Faculty Publications

Among stroke survivors, linguistic and non-linguistic impairments exhibit substantial inter-individual variability. Stroke lesion volume and location do not sufficiently explain outcomes, and the neural mechanisms underlying the severity of aphasia or non-verbal cognitive deficits remain inadequately understood. Converging evidence supports the idea that white matter is particularly susceptible to ischaemic injury, and long-range fibres are commonly associated with verbal and non-verbal function. Here, we investigated the relationship among post-stroke aphasia severity, cognition, and white matter integrity. Eighty-seven individuals in the chronic stage of stroke underwent diffusion MRI and behavioural testing, including language and cognitive measures. We used whole-brain structural connectomes …

This approach aims to enhance eradication of pathogens while minimizing systemic side effects associated with prolonged antibiotic use. This narrative review encompassed 10 articles focused on all three procedures of surgical intervention for periprosthetic joint injection (PJI) following total hip arthroplasty (THA): debridement, antibiotics, and implant retention (DAIR), single-stage revision arthroplasty, and two-stage revision arthroplasty. Recent studies report success rates ranging from 90 to 100% in patients undergoing DAIR, 82 to 100% in single-stage revision arthroplasty, and 80% in two-stage …

Human-Human Vs Human-Ai Therapy: An Empirical Study, Mohammad Amin Kuhail, Nazik Alturki, Justin Thomas, Amal K. Alkhalifa, Amal Alshardan

All Works

In many nations, demand for mental health services currently outstrips supply, especially in the area of talk-based psychological interventions. Within this context, chatbots (software applications designed to simulate conversations with human users) are increasingly explored as potential adjuncts to traditional mental healthcare service delivery with a view to improving accessibility and reducing waiting times. However, the effectiveness and acceptability of such chatbots remains under-researched. This study evaluates mental health professionals’ perceptions of Pi, a relational Artificial Intelligence (AI) chatbot, in the early stages of the psychotherapeutic process (problem exploration). We asked 63 therapists to assess therapy transcripts between a human …

Thigh Perforator Exchange: Intraflap Perforator Augmentation Of Anterolateral Thigh Free Flaps, Patrick A. Palines, Matthew E. Nungesser, Morgan E. Baudoin, Devin M. Melancon, Mark W. Stalder

School of Medicine Faculty Publications

Peripheral perfusion in large anterolateral thigh flaps may be inadequate if perforator zones are not properly planned during flap design and harvest, and variations in vascular anatomy can contribute to operative difficulty and morbidity. Intraflap anastomosis of extrinsic perforators may allow for augmentation of perfusion while avoiding significant intramuscular dissection. Adaptation of the perforator exchange technique, previously described in autologous breast reconstruction, optimizes vascular flow in anterolateral thigh flaps. Here, we present a technique for intraflap perforator anastomosis (the thigh perforator exchange) and illustrate its use in a subset of patients. This technique is relatively simple and rapid to perform …

Exploring The Immune System’S And Silybin’S Impact On Cancer Cachexia, Patrice Cunningham

Theses and Dissertations

Cancer cachexia is a complex syndrome that is characterized by the unintentional loss of body weight with or without fat loss. During cancer cachexia, there is an increase in inflammation consistent with various inflammatory cytokines such as tumor necrosis factor-alpha (TNF-α), Interleukin-1 beta (IL-1β ), and interleukin-6 (IL-6); all of which are known to increase proteolysis and aid in the progression of muscle loss and weakness. Immune cells such as macrophages are increased during cachexia and are known to have varying effects on muscle inflammation, regeneration, and the progression of fibrosis in a disease state. However, therapies aimed solely at …

The Effect Of Covid-19 Restrictions On The Social Support Experiences Of Black Women Giving Birth In South Carolina Hospitals During The First Year Of The Covid-19 Pandemic (2020) As Compared To A Previous Birth, Tiffany Eva Byrd

Theses and Dissertations

The United States is experiencing a maternal health crisis, which disproportionately affects Black women. Black women die from pregnancy-related causes two to three times as often as their White counter parts, and the majority of maternal death are preventable. In recent years, public health and national governing authorities have devoted resources to monitoring the health crisis and raising the public’s knowledge of warning signs; however, maternal mortality rates continue to rise. Noted contributors to Black maternal mortality include, but are not limited to, racism, delayed treatment and response to health emergencies, and lack of social and emotional support during childbirth, …

Dysregulation Of Dopamine Dynamics Through Monoamine Transporters By The Hiv-1 Protein Transactivator Of Transcription, Sarah Davis

Theses and Dissertations

Prevalence of HIV-1 Associated Cognitive Disorders (HAND) persists in the era of combined antiretroviral therapies, causing impaired memory, motor function, and decreased quality of life. Evidence from clinical samples of persons with HAND has implicated dopamine, as well as the HIV-1 viral protein transactivator of transcription (Tat) as key molecules associated with disease progression. Through molecular modeling, in vitro and in vivo mutagenesis our lab has characterized Tat as a negative allosteric modulator for monoamine transporters, including the dopamine transporter (DAT), vesicular monoamine transporter (VMAT-2), and norepinephrine transporter. While this work has shed light on how Tat impacts the function …

Addressing A Crisis In Nursing Practice: Exploring The Impact Of Multimedia Case-Based Learning On The Clinical Judgment Of Undergraduate Nursing Students, Macy Jenette Bennett

Theses and Dissertations

Clinical judgment is a priority nursing skill to ensure the delivery of safe and effective nursing care. New graduate nurses and nursing students lack the clinical judgment skills that are necessary for entry-level nursing practice. Nurse educators must therefore implement teaching strategies that facilitate clinical judgment. This study evaluated the clinical judgment of undergraduate nursing students after the implementation of multimedia case studies related to the concept of perfusion. Two research questions guided this study: (a) in what ways do undergraduate nursing students demonstrate clinical judgment after completing a series of perfusion-related multimedia case studies and (b) to what extent …

Faculty, Staff and Student Publications

A major and irreversible complication of diabetes is diabetic peripheral neuropathy (DPN), which can lead to significant disability and decreased quality of life. Prior work demonstrates the peptide hormone Angiotensin II (Ang II) is released locally in neuropathy and drives inflammation and impaired endoneurial blood flow. Therefore, we proposed that by utilizing a local thermoresponsive hydrogel injection, we could deliver inhibitors of angiotensin-converting enzyme (ACE) to suppress Ang II production and reduce nerve dysfunction in DPN through local drug release. The ACE inhibitor captopril was encapsulated into a micelle, which was then embedded into a reversibly thermoresponsive pluronics-based hydrogel matrix. …

Theses and Dissertations

The prevalence of food insecurity across college campus in the United States has been widely explored, with the primary focus placed on large, 4-year, primarily White institutions. Less is known about the prevalence of food insecurity and the impact it may have on health behaviors among minority serving institutions, including Historically Black Colleges and Universities (HBCU). Young adults attending college, and more specifically student-athletes (SAs), are typically in a new place, facing new stressors and high rates of food insecurity, which in turn may play a critical role in their current health status as it pertains to meeting their energy …

Associations Between The Use Of Ssri Medication In Older Adults And Cognitive Decline And Impairment, Paige Jones

Theses and Dissertations

Previous research has indicated that depression is a risk factor for dementia. Since SSRI medication is the most common treatment for depression, it is important to determine if SSRIs are associated with reduced dementia and better cognitive outcomes. Using longitudinal data from the 2004-2014 waves of the Health and Retirement Study merged with the 2005 Prescription Drug Study, we examined potential associations between SSRI and TCA medication and cognitive impairment and cognitive decline. The study population consisted of 1,775 older adults who participated in the PDS in 2005. We found that SSRIs were associated with significantly higher odds of cognitive …

Internalizing Mental Health Symptoms And Nicotine Use Among Adolescents In Canada, England, And The Us From 2020-2022, Emily E. Hackworth

Theses and Dissertations

Background: There is a well-established bi-directional relationship between cigarette smoking and internalizing mental health (IMH) symptoms (e.g., symptoms of depression, symptoms of anxiety). However, it is unclear whether IMH symptoms are associated with using different types of nicotine products among adolescents, as adolescents are using a variety of nicotine products, including combustible products (cigarettes), non-combustible products (e-cigarettes), or combinations of both types of products. This dissertation examines associations between IMH symptoms and current use of various types of nicotine products across three countries from 2020-2022.

Methods: Data come from the 2020-2022 waves of the International Tobacco Control (ITC) Adolescents Tobacco …

Sodium alginate is a natural polymer that has been widely used as a drug delivery system due to its controlled-release qualities and low cellular toxicity. These capsules are effective at transporting therapeutics in various diseased animal models. Retinitis Pigmentosa is an incurable genetic disease affecting the retina, which causes gradual blindness as the disease progresses. In our study, we injected cell-based sodium alginate capsules into the vitreous cavity of C57BL/6 and Pde6b^rd10/J mice to observe the migration of these capsules in both wildtype and diseased mouse models over a course of 2 weeks. Our intention was …

Neural Mechanisms Of Estrogen And Inflammation In Female Stress Susceptibility, Samantha Jane Bouknight

Theses and Dissertations

Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) are highly debilitating psychiatric disorders that notably share stress as an etiological factor. Stress is a common occurrence experienced daily by virtually everyone and, while most people are resilient, a substantial portion of the population exhibit risk factors that yield them susceptible to developing stress-related psychiatric disorders. One prominent factor that has long been known to increase this risk is the female biological sex with women presenting at least twice as often with disorders like PTSD and MDD compared to men. Interestingly, this bias exists distinctly during the reproductive years and …

Association Between Autoimmune Diseases And Lymphoma Risk Using The Uk Biobank, Hannah Grace Dice

Theses and Dissertations

Background. Lymphoma is a blood cancer that develops when white blood cells multiply in an abnormal way and collect in the lymph nodes. Autoimmune diseases result when the immune system is overactive, causing it to attack and damage the body’s own tissues. Limited studies have been conducted to investigate the association between autoimmune diseases and lymphoma risk.

Literature review. Based on prior research, six autoimmune diseases (rheumatoid arthritis (RA), lupus, Sjögren’s syndrome, sarcoidosis, Crohn’s disease, and ulcerative colitis (UC)) were examined to better understand their association with lymphoma risk. Prior research has concluded that certain aspects of these autoimmune diseases …

Chronic itch often clinically coexists with anxiety symptoms, creating a vicious cycle of itch-anxiety comorbidities that are difficult to treat. However, the neuronal circuit mechanisms underlying the comorbidity of anxiety in chronic itch remain elusive. Here, we report anxiety-like behaviors in mouse models of chronic itch and identify γ-aminobutyric acid-releasing (GABAergic) neurons in the lateral septum (LS) as the key player in chronic itch-induced anxiety. In addition, chronic itch is accompanied with enhanced activity and synaptic plasticity of excitatory projections from the thalamic nucleus reuniens (Re) onto LS GABAergic neurons. Selective chemogenetic inhibition of the Re → LS circuit notably …
