Transcranial Alternating Current Stimulation As An Adjuvant For Nonfluent Aphasia: A Proof-Of-Concept Study, Lynsey M. Keator, Lisa Johnson, Roger Newman-Norlund, Kyler Spell, Samaneh Nemati, Leigh Ann Spell, Dirk B. Den Ouden, Christopher Rorden, Julius Fridriksson

Department of Speech-Language Pathology Faculty Papers

Effective rehabilitation tools are essential for improving language outcomes in chronic aphasia. Speech entrainment is a behavioral treatment that has shown promise in enhancing speech output in nonfluent aphasia, potentially by acting as an external mechanism to synchronize anterior and posterior language regions in the left hemisphere. Transcranial alternating current stimulation has been hypothesized to enhance functional connectivity between brain regions by amplifying endogenous oscillations. This proof-of-concept study explored whether high-definition tACS (HD-tACS) could improve speech fluency in nonfluent aphasia when paired with speech entrainment. In a double-blind, pseudorandomized study, 1 mA of HD-tACS at 7 Hz was applied to …

Whole-Blood, Concentrated, And Micro–Dose Del Nido Cardioplegia In Adult Cardiac Surgery: A Scoping Review, Christian Iulianelli

Student Works

1. A.     Background/Introduction: Del Nido cardioplegia was originally developed for pediatric cardiac surgery to provide prolonged myocardial protection with a single-dose strategy. Its adoption in adult cardiac surgery has led to multiple modified formulations, including whole-blood, concentrated, and bloodless strategies. Given expanding clinical use and variation in technique, a structured mapping of the adult evidence base is warranted.
2. B.     Methodology: This scoping review followed PRISMA-ScR guidance. PubMed and CINAHL were searched, yielding 88 records. After duplicate removal and screening, 18 studies met inclusion criteria. Data were charted on study design, cardioplegia formulation, patient population, myocardial biomarkers, arrhythmias, renal outcomes, transfusion requirements, …

Evolving Solutions For Red Blood Cell Preservation, Ali Alkafaji, Charles A. Elder, Mohammad Zaidi, Kavin Parthiv, Michael A. Menze

The Cardinal Edge

In emergencies such as natural disasters, armed conflicts, or during outer space missions, the availability of transfusable blood can mean the difference between life and death. Red blood cells (RBCs) must be stored at +4 ± 2 °C and have a shelf life of just 42 days, which makes maintaining a stable blood supply during adverse conditions extraordinarily challenging. This challenge was especially apparent during the COVID-19 pandemic when hospitals faced severe blood shortages. Freeze-drying, or lyophilization, offers a promising avenue to extend the shelf life of RBCs for transfusion during crises. However, a significant hurdle in dry preservation is …

Evaluating Assistive Technology-Mediated Hepatitis B Education On At-Risk Behaviours Among In-School Adolescents With Hearing Impairment In Oyo State, Nigeria, Suen. E. Olalekanmi, J. O. Odelola, O. O. Isaiah

The 2026 Assistive Technology for Persons with Intellectual and Physical Disabilities Conference

Background: Adolescents with hearing impairment experience heightened vulnerability to health risks, largely due to limited access to accurate, accessible, and comprehensible health information. Communication barriers often restrict their understanding of disease prevention, resulting in inadequate health literacy and increased engagement in behaviours that may expose them to preventable infections such as HB. Despite the availability of effective vaccines and preventive measures, HB remains a significant public health concern in Nigeria. This situation underscores the urgent need for researchers, educators, and healthcare professionals to develop and prioritise inclusive health education strategies that address the unique communication needs of adolescents with hearing …

When The Machine Lets Go: Designing Drug Delivery Devices Patients Can Rely On, Katie Stubits, Liam Brennan

Student Research Symposium (SRS)

Semi-automated drug delivery systems, such as closed-loop insulin pumps, smart infusion devices, and patient-controlled analgesia (PCA) tools, are transforming healthcare by improving dosing precision and empowering patients with greater autonomy. However, their safety and efficacy depend critically on trust calibration—the dynamic alignment between patient trust in automation and actual system reliability (Hoff & Bashir, 2015; Lee & See, 2004). Miscalibrated trust can lead to misuse or disuse, jeopardizing patient safety in high-stakes contexts (Fallon et al., 2010). Grounded in theories of human–automation interaction (Lee & See, 2004) and recent empirical research findings (Zheng et al., 2022), this work conceptualizes trust …

Breaking Into Hiv-1'S Epigenetic Vault: Cure Strategies To Eliminate The Viral Reservoir, Joanna Jones, Chelsea Gunderson, Brian Wigdahl, Michael Nonnemacher

Kimmel Cancer Center Faculty Papers

Human immunodeficiency virus type 1 (HIV-1) is a retrovirus that integrates into the host cell's DNA as a provirus. Transcription from the provirus is regulated in large part by cellular proteins and epigenetic factors. These may be repressive or permissive to productive infection. The host factors that regulate this balance are therefore attractive targets for HIV-1 therapeutics. Indeed, proviral chromatin is the focus of two of the current HIV-1 cure strategies. "Shock and Kill" uses latency reversal agents to open the provirus's chromatin, promoting high levels of gene expression that induce the killing of infected cells. "Block and Lock" uses …

Defining A Multi-Omic, Ai-Enabled Stool Screening Paradigm For Colorectal Cancer: A Consensus Framework For Clinical Translation, Arturo Loaiza-Bonilla, Yan Leyfman, Viviana Cortiana, Rhys Crawford, Shivani Modi

Einstein Health Papers

Colorectal cancer (CRC) develops through both conventional adenoma-carcinoma and serrated neoplasia pathways, yet noninvasive screening still under-detects the advanced precursor lesions that enable true cancer prevention. Stool-based screening reduces CRC mortality, but its preventive impact remains constrained by limited detection of advanced precancerous lesions (APLs), including advanced adenomas and sessile serrated lesions. Next-generation multitarget stool DNA assays (mt-sDNA; e.g., Cologuard Plus) have established high sensitivity for CRC and specificity approaching 94%, leaving improved APL detection as the principal opportunity for innovation. This review presents a consensus framework for a multi-omic stool screening paradigm that integrates host epigenetic markers (DNA methylation) …

Virtual Reality For The Management Of Postoperative Pain And Anxiety In Children And Adolescents Undergoing Nuss Repair Of Pectus Excavatum: Randomized Controlled Trial, Charlotte M. Walter, Dillon Froass, Nora Bell, Lauren Haack, Chloe Boehmer, Claudia Bruguera Torres, Rachel Spivak, Max Chou, Kristie Geisler, Keith O'Conor, Sara E. Williams, Lili Ding, Christopher D. King, Vanessa A. Olbrecht

Department of Medicine Faculty Papers

BACKGROUND: Virtual reality (VR) is a novel technology with implications for pain and sensory processing. VR may serve as a novel, scalable method to deliver clinically validated therapy for pain management as an alternative or adjunct to opioids for acute pain. Given that psychological factors and pain perception are both components of postoperative pain, it may also be beneficial to incorporate modalities that decrease anxiety, such as active relaxation and guided meditation with VR. Unfortunately, these therapies are not widely available due to multiple barriers. VR has the potential to deliver pain-reducing, psychologically based therapy to children, thereby enhancing multimodal …

A number medical professional associations have published statements affirming their commitment to providing access to patient-centered healthcare for LGBTQIA+ patients. Unfortunately, there is a lack of research related to the factors that influence perceived knowledge of and attitudes toward the LGBTQIA+ community among healthcare providers. More information on what factors impact perceived knowledge of and attitudes toward the LGBTQIA+ community would assist with creating interventions that improve perceived knowledge and attitudes toward the LGBTQIA+ community. The purpose of this study was to …

Awareness Of Native American Living Conditions Among Athletic Trainers, Laurel Trail, Brandon Warner, Rebecca Peebles, Robert French, Lynzi Warner, S. Andrew Cage

Clinical Practice in Athletic Training

Context: Native Americans and First Nations People have dealt with healthcare disparities that have been documented in previous studies. One factor that appears to have played a role in these disparities was the Indian Removal Act of 1851 which established the first Native American reservations. The foundation of these reservations led to many Native Americans being displaced from areas where the United States was establishing new population centers. This has led many individuals not understanding the conditions that Native Americans live in. Lack of knowledge of the conditions patients live in may negatively affect clinicians’ ability to provide optimal healthcare. …

Sleep And Stress Experienced By Collegiate Baseball Players During A Fall Season, Andrew R. Gallucci, Katie M. Lee, Eric Rash, Jeremy A. Bigalke, Jason R. Carter

Clinical Practice in Athletic Training

Introduction: College students are notoriously poor sleepers due to academic and social demands. Collegiate athletes have additional athletic responsibilities that can also affect sleep. During a season, baseball players experience prolonged bouts of high intensity activity that increase the need for recovery and sleep. Athletes can also experience higher perceived stress levels, a factor also known to impact sleep. Reduced sleep quality and quantity during a competitive season can impede recovery and decrease performance. The present study sought to determine the relationships between sleep [Total Sleep Time (TST), Sleep Efficiency (SE), Sleep Onset Latency (SOL), Awakenings] and stress over a …

Extensor Hallucis Longus Focal Dystonia In A Patient With Parkinson’S Disease: A Case Study, Jessika Truax, Linda Bobo, Keilea Sumrall

Clinical Practice in Athletic Training

Introduction: Parkinson’s Disease (PD) is a common neurodegenerative disorder that affects a person’s ability to produce dopamine and control motion of the body. PD affects 1% of people over the age of 65, but the disease can occur earlier and later in life. The uncontrollable movement of any body part involved with PD is referred to as a tremor. Pathophysiology of PD causes the thalamus to have a decreased activation of the frontal cortex, thus decreased motor activity. Patients commonly have dystonia mostly in the foot resulting in striatal toe. Optional pain relief is a tenotomy of the extensor hallicus …
