Pharmacy Faculty Articles and Research

Gadolinium nanoparticles (GdNPs) have gained increasing attention as multifunctional metal-based nanoplatforms that extend far beyond their traditional use as magnetic resonance imaging (MRI) contrast agents. Their specific magnetic properties, tunable physicochemical features, and tunable biocompatibilities with biocompatible coatings give them great potential as drug delivery and theranostic applications. They offer greater stability, lower systemic toxicity, and more surface modification options compared to molecular gadolinium chelates. The functionalized GdNPs not only show excellent properties as drug carriers for their specific indications but also serve as agents in various imaging modalities with superior therapeutic efficacy by means of radio sensitization and magnetically …

Gastrointestinal Symptoms After Sport-Related Concussion In Irish Athletes, Emma Finnegan, Ed Daly, Katherine Hunzinger, Lisa Ryan

Department of Exercise Science Faculty Papers

Background/Objectives: Sport-related concussion (SRC) elicits multi-systemic symptoms, including nausea, fatigue, and cognitive changes. Gastrointestinal (GI) symptoms are not well captured in current concussion assessments and may be under-recognised in clinical follow-up. GI disturbances may influence intake tolerance and day-to-day fuelling during post-SRC recovery. This study investigated the prevalence and severity of self-reported GI symptoms in Irish athletes after their most recent SRC, examined sex-based patterns, and evaluated the rationale for integrating GI symptom checks into standard concussion tools (e.g., SCAT6) and post-injury monitoring. Methods: An online survey was completed by recreational, competitive, and elite athletes who retrospectively self-reported concussion history, …

No Effect In Plasma Corticosterone Levels After Observation Of Diseased Conspecifics, B. M. Hardy, M. Chang, S. Mccallum, S. Santangelo, Patricia C. Lopes

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Organisms commonly respond to stressors in their environment by increasing the secretion of corticosterone (CORT). While increased CORT is acknowledged as a response to predation risk by organisms inhabiting a landscape of fear, new research raises the potential for changes in CORT as a response to the risk of infection by organisms in their environment. An increase in CORT of a healthy, uninfected individual in response to their perception of the risk of infection in their environment could change their susceptibility to infection, highlighting a significant role for CORT to alter host–pathogen dynamics. To investigate the effects of infection risk …

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 Multi-State Look Into Early Intervention Speech-Language Pathologists’ Confidence Identifying And Diagnosing Autism, Allison Gladfelter, Adelaide Parr, Anna Cannone, Sarah O'Connor

CISLL Publications

Purpose: Although autism can be reliably diagnosed by 18 months of age, long wait times and limited access to qualified providers prevent families from obtaining timely diagnostic services. Trained speech-language pathologists (SLPs) are qualified to diagnose autism, ideally as part of a multidisciplinary team. SLPs working on early intervention (EI) teams are well-situated to help close this diagnostic wait time gap. The purpose of this survey study was to explore EI SLPs’ experiences serving autistic children, confidence in identifying and diagnosing autism, and their perceptions of barriers or facilitators to diagnostic confidence and wait times.

Method: 287 EI SLPs from …

The Role Of Personality In Collegiate Athletes’ Indicators Of Performance And Injury Experiences – A Mixed Methods Study, Allison Traub

Doctoral Dissertations and Projects

This mixed methods study explores the impact of collegiate athletes' indicators of personality traits as attributed to athletic performance, injury experiences, and sport identity. Sports often emphasize physical abilities, yet the role of personality is equally significant—though it has received comparatively little attention in psychological research. This research addresses such a gap through examining how personality traits shape athletes’ competitive behavior along with coping strategies. The traits are defined within the 16 Personalities framework using Myers-Briggs Type Indicator (MBTI) and how it influences just how athletes recover. This research will explore research questions such as how personality affects college athletes' …

Clinical And Economic Impact Of Vascular Access Teams Utilizing An Ic-Ecg-Based Tip Confirmation System For Peripherally Inserted Central Catheters., Gustavo Rc De Freitas, Sanjay A Patel, Shigeki Fujitani, Yusuke Terasaka, Angel A Sarabia Collazo, Andrew Barton, Leanne Ruegg, Amanda Griffin, Matthew O'Brien, Idal Beer

Heart and Vascular Articles

INTRODUCTION: Peripherally inserted central catheters (PICCs) are commonly used in clinical practice. Historical PICC placement methods (e.g. fluoroscopy-guided placement or blind insertion with confirmatory chest X-ray) have many limitations and are associated with longer wait times, treatment delays, and potential risks to patient safety. One such way of addressing some of these issues is the use of dedicated systems that integrate ultrasound vessel selection and PICC insertion, magnetic catheter tip navigation, and intracavitary electrocardiogram-based tip confirmation (IC-ECG). The uptake of these systems has been slow in some parts of the world. This narrative review aims to assess the clinical and …

Aging In The Shadows: Szekler Cemeteries And The Case For Recognizing Elderly Populations In Bioarchaeology, Katie M. Mcgrath

USF Tampa Graduate Theses and Dissertations

The study of aging in past populations lies at the intersection of bioarchaeology and paleodemography, offering insight into both biological processes and lived social experience. Despite this potential, older adults are often rendered “invisible” in skeletal assemblages due to methodological and cultural biases. This thesis addresses this gap through a rare, community-based study of aging among the Székely population of Transylvania. By integrating osteological analysis of individuals (11th–19th centuries) from the archaeological Papdomb church cemetery with demographic data derived from the modern cemetery headstones (ca.1850–present), this research examines patterns of aging, longevity, and elder visibility across a culturally and spatially …

Department of Medicine Faculty Papers

Laparoscopic renal denervation (RDN) represents a specialized approach for hypertension, particularly when conventional methods face limitations. While catheter-based RDN has demonstrated significant efficacy in recent large-scale clinical trials and has been integrated into international guidelines, its effectiveness can be constrained by complex renal anatomy or incomplete ablation. We developed a novel laparoscopic RDN system, comprising an integrated radiofrequency (RF) clamp, RF generator, and cooling pump, to achieve more controlled adventitial ablation. This study aims to evaluate the safety, feasibility, and optimal parameters of this new system in a preclinical swine model. Sixteen pigs were divided into an immediate group ( …
