Clinical Practice in Athletic Training

Context: The transition in athletic training education allows for unique and new opportunities in postprofessional education. The Doctor of Athletic Training (DAT) degree is one of the postprofessional education pathways that could provide athletic trainers advancement in clinical practice, practice leadership, and scholarship. However, there is no data on the educational outcomes of DAT programs and what graduates should expect from their experiences. The aim of this study was to explore whether DAT programs are delivering curricula consistent with the development of clinical scholars with advanced knowledge and skills that are needed for high-level patient care and literature relative to …

Athletic Trainers’ Familiarity With Potential Concussion Biomarkers: A Descriptive Study, T R. Campbell, B J. Davis, J C. Martinez, J M. Cavallario

Clinical Practice in Athletic Training

Introduction: An estimated 3.8 million individuals sustain a concussion annually in the United States. Despite the high number of cases, this number may not accurately depict the true incidence rate due to underreporting of symptoms by patients. With current concussion tools relying heavily on subjective input from patients, it is imperative that a valid and reliable objective tool, such as a clinical biomarker, is identified to improve concussion diagnosis and management. If such a biomarker is identified, it will be essential that athletic trainers (ATs) be familiar with how biomarkers could be used. The purpose of this study was to …

Athletic Training Preceptors’ Experience With Interprofessional Education And Collaborative Practice In The Clinical Learning Environment, A Bender

Clinical Practice in Athletic Training

Introduction: Professional athletic training (AT) programs are now required to align their educational curricula with the Institute of Medicine's (IOM) core competencies, preparing students to work in dynamic, interprofessional healthcare teams to strategically address patient outcomes. Although interprofessional education and collaborative practice (IPECP) is commonly implemented in didactic settings, our understanding of how IPECP is implemented by AT preceptors in various clinical settings is limited. The purpose of this study was to gain a greater understanding of AT preceptors’ experience with IPECP and how they implement this with students in their clinical settings. Methods: A convergent mixed-methods design was used …

Using Alums Involvement To Increase Student Investment In An Athletic Training Program, C J. Heffner, A L. Green

Clinical Practice in Athletic Training

Introduction: Student investment and retention are not new concerns among athletic training program directors. Graduate programs are expected to meet minimum enrollment standards to demonstrate the need for the program. Programs that are unable to maintain student enrollment will be eliminated by institutions experiencing financial stress. Retention strategies and benefits have previously been investigated among undergraduate students and across disciplines. One common theme in the research is that student retention increases when students feel a sense of belonging from the faculty, staff, and peers in their program. There is less research on the retention of graduate students, but the themes …

Using Data In The Classroom To Drive Instructional Design And Delivery, L E. Eberman, J P. Young

Clinical Practice in Athletic Training

Introduction: Roughly half of ATP program directors include education on transgender health care in their programs, and even fewer report having the competence to do so. However, professional-level accreditation standards (56, 57, and DEI 2) require that programs have faculty with contemporary expertise to educate students on these outcomes. Current research suggests a comprehensive transgender and sexual health curriculum, including safe-zone training, traditional lecture, lab, and project-based instruction, was partially effective at changing students’ attitudes toward transgender patients but did not improve sexual health care delivery during a standardized patient encounter. The purpose of this project was to evaluate the …

Traveling The Pathway To A Culturally Competent Health Care Provider: Incorporating Study Abroad Into Your Curriculum, A L. Johnston Green, C J. Heffner

Clinical Practice in Athletic Training

Introduction: As athletic training employment settings expand and diversify, so does the patient population with whom these healthcare providers interact. This growth furthers the need to ensure that students enrolled in an athletic training program (ATP) accredited by the Commission on Accreditation of Athletic Training Education (CAATE) are educated to provide culturally competent care. Culturally competent care is provided when decisions made diminish the inequalities that may be present in a system based upon a patient’s individual circumstances. Implementing cultural competency education may be integrated into athletic training education in various manners as necessitated by each institution’s unique circumstances. Programs …

Exploring The Work-Related Quality Of Life Of Athletic Trainers In Physician Practice, N T. Anderson, K E. Games, J P. Young, M J. Rivera, L E. Eberman

Clinical Practice in Athletic Training

Introduction/Context: The National Athletic Trainers’ Association (NATA) identified the vitality of the athletic training profession as a research priority, which includes exploring solutions to improve work-life balance. There is a common perception that athletic trainers (AT) working in the physician practice setting have lower work-life conflict and increased job satisfaction, but no data to support this belief. Work-Related Quality of Life (WRQoL) has been studied in some healthcare settings but has not been studied in any athletic training clinical practice setting. Therefore, the purpose of this study is to investigate the WRQoL of athletic trainers in physician practice. Methods: A …

How Do Athletic Trainers Impact Patient Health Literacy?: A Critically Appraised Topic, T Bouchard

Clinical Practice in Athletic Training

Introduction/Context: Health Literacy is defined as “the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions.” An estimated 80 million Americans are estimated to have low levels of health literacy. Low health literacy has been linked to poor patient outcomes and decreased usage of health services. Athletic trainers are multiskilled medical professionals recognized by the American Medical Association, trained in, among other things, wellness promotion and education, injury prevention and rehabilitation, and primary care. Although athletic trainers have traditionally been employed in collegiate/elite sports, many are …

Disorganization Of Actin Within The Shafts Of Stereocilia Is A Key Difference Between Temporary And Permanent Noise-Induced Hearing Loss (Nihl), Shadan Hadi

Theses and Dissertations--Physiology

During sound stimulation, mechanosensory stereocilia of the auditory hair cell pivot around their bases, where their actin cores become denser and form rootlets protruding into the cuticular plate. It is believed that actin-based cuticular plate provides a stable mechanical support for stereocilia, while rootles are responsible for their pivotal flexibility and life-long resilience to mechanical stimuli. Not surprisingly, damage to the stereocilia bundles is known as a hallmark of permanent noise-induced hearing loss (NIHL). Yet, despite decades of NIHL studies, it is still unknown which ultrastructural changes in the stereocilia bundles are evoked directly by mechanical overstimulation.

Here, we explored …

Cyp6g2 Is The Major P450 Epoxidase Responsible For Juvenile Hormone Biosynthesis In Drosophila Melanogaster, Qiangqiang Jia, Liu Yang, Jiamin Wen, Suning Liu, Di Wen, Wei Luo, Weihua Wang, Subba R. Palli, Li Sheng

Entomology Faculty Publications

Background Juvenile hormones (JH) play crucial role in regulating development and reproduction in insects. The most common form of JH is JH III, derived from MF through epoxidation by CYP15 enzymes. However, in the higher dipterans, such as the fruitfly, Drosophila melanogaster, a bis-epoxide form of JHB3, accounted most of the JH detected. Moreover, these higher dipterans have lost the CYP15 gene from their genomes. As a result, the identity of the P450 epoxidase in the JH biosynthesis pathway in higher dipterans remains unknown.

Results In this study, we show that Cyp6g2 serves as the major JH epoxidase responsible for …

The Mechanoreceptor Piezo Is Required For Spermatogenesis In Bombyx Mori, Zhongjie Zhang, Xiaojing Liu, Bo Hu, Kai Chen, Ye Yu, Chenxin Sun, Dalin Zhu, Hua Bai, Subba Reddy Palli, Anjiang Tan

Entomology Faculty Publications

Background The animal sperm shows high diversity in morphology, components, and motility. In the lepidopteran model insect, the silkworm Bombyx mori, two types of sperm, including nucleate fertile eupyrene sperm and anucleate unfertile apyrene sperm, are generated. Apyrene sperm assists fertilization by facilitating the migration of eupyrene spermatozoa from the bursa copulatrix to the spermatheca. During spermatogenesis, eupyrene sperm bundles extrude the cytoplasm by peristaltic squeezing, while the nuclei of the apyrene sperm bundles are discarded with the same process, forming matured sperm.

Results In this study, we describe that a mechanoreceptor BmPiezo, the sole Piezo ortholog in B. mori, …

Acute Gastrointestinal Permeability After Traumatic Brain Injury In Mice Precedes A Bloom In Akkermansia Muciniphila Supported By Intestinal Hypoxia, Anthony J. Desana, Steven Estus, Terrence A. Barrett, Kathryn E. Saatman

Physiology Faculty Publications

Traumatic brain injury (TBI) increases gastrointestinal morbidity and associated mortality. Clinical and preclinical studies implicate gut dysbiosis as a consequence of TBI and an amplifier of brain damage. However, little is known about the association of gut dysbiosis with structural and functional changes of the gastrointestinal tract after an isolated TBI. To assess gastrointestinal dysfunction, mice received a controlled cortical impact or sham brain injury and intestinal permeability was assessed at 4 h, 8 h, 1 d, and 3 d after injury by oral administration of 4 kDa FITC Dextran prior to euthanasia. Quantification of serum fluorescence revealed an acute, …

Changes In Flanker Task Performance Following High-Intensity Exercise In Endurance Athletes, Felix E. Cottet-Puinel

Dissertations, Master's Theses and Master's Reports

Executive function performance following acute aerobic exercise can be influenced by multiple variables. However, little is known about the lasting effects of these exercise-induced changes. This study aimed to determine the extent to which exercise intensity impacts executive function. 14 young endurance-trained adults (5 female, 9 male) performed an Eriksen flanker task before and immediately after running high-intensity until failure and isochronal moderate-intensity (~12 min). Pre- to post-exercise-induced changes in reaction time (ms), accuracy (%), and self-reported mental effort (1-9 rating) were analyzed by overall tasks and through tasks subsections. Results showed improvement in reaction time following high- and moderate-intensity …

Structural And Functional Consequences Of Pde6 Prenylation In Rod And Cone Photoreceptors, Faezeh Moakedi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Phosphodiesterase-6 (PDE6) serves as a pivotal component in the phototransduction pathways of both cone and rod photoreceptors. In cones, PDE6 consists of tetrameric subunits: inhibitory (γ') and catalytic (α'). The catalytic subunit, PDE6α', contains a C-terminal prenylation motif. Deletion of this motif is associated with achromatopsia (ACHM), a form of color blindness. The mechanisms underlying the disease and the roles of PDE6 lipidation in vision remain elusive. Meanwhile, rod PDE6 is composed of α and β catalytic subunits and γ inhibitory subunits, with alterations in the C-terminal "prenylation motif" of PDE6β linked to retinitis pigmentosa (RP) pathology. In this comprehensive …

Estradiol’S Role In Timely Puberty Onset In The Ewe, Eliana Gerardine Aerts

Graduate Theses, Dissertations, and Problem Reports (ETD)

In female sheep, the release of gonadotropin-releasing hormone (GnRH) from the hypothalamus triggers luteinizing hormone (LH) to be released from the pituitary. Luteinizing hormone, in turn, acts on the ovaries to elicit estradiol (E₂) release. E₂ acts in a negative feedback manner to control the amount of LH released. The increase in LH release that drives puberty onset results from a decrease in sensitivity to E₂ as the animal ages. However, the neural mechanisms mediating this change in sensitivity are not known, as is where in the hypothalamus E₂-negative feedback occurs. In the arcuate …

Puberty-Associated Changes In Kiss1r, Mc3r, And Mc4r In The Ewe, Ashleigh Caitlyn Thomson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The neural mechanisms that control the onset of puberty are not completely understood. In livestock, the onset of puberty relies on an increase in gonadotropin releasing hormone (GnRH) and luteinizing hormone (LH). Kisspeptin, neurokinin B, and dynorphin neurons (KNDy) and their receptors, Kiss1r, NK3R, and KOR, respectively, are important regulators of puberty. Previous data from our laboratory has shown that KNDy neurons may be responding to other inputs, including the melanocortin system, that will affect the timing of puberty. Given this, we examined kisspeptin receptor (Kiss1r) mRNA expression in GnRH neurons as well as examining melanocortin 3 and 4 receptor …

Crayfish Tube-Feeding Methodology, Phoenix Johnson

Williams Honors College, Honors Research Projects

The purpose of this paper was to use a tube feeding method on crayfish to expose them to substances through ingestion rather than the gill. This was done to mimic human ingestion of substance to aid in crayfish research involving substances that are normally ingestion. This was done by using a pipette to inject grains of sand into the mouth of the crayfish. To determine if the method worked and successfully went into the stomach the grains of sand were recovered and counted under a microscope after certain increments of time post injection.

Impact Of Cannabidol (Cbd) On Daphnia Magna Heart Rate, Joanna Ross

Williams Honors College, Honors Research Projects

In 2023, Ohio legalized recreational cannabis use for adults over 21; however, research on the physiological effectsof cannabis-derived compounds, particularly cannabidiol (CBD), remains limited due to i ts narcotics classification.While CBD is known to antagonize Cannabinoid Receptor 1 (CB1), a receptor found in the cardiac tissue of a numberof organisms, the effects on cardiac activity are not fully understood. This study aimed to investigate the impact ofCBD on heart rate in Daphnia magna. The hypothesis posited that CBD would increase heart rate in Daphnia byantagonizing CB1 receptors or equivalent G-protein-coupled receptors. The subjects were exposed to threetreatments: control (dechlorinated water), …
