Visual And Refractive Outcomes Of Premium Intraocular Lens Implantation In Post-Refractive Eyes Undergoing Refractive Lens Exchange Or Cataract Surgery, Simon Zakhari, Abhilash Guduru

Cumberland Medica

Historically, premium intraocular lenses (IOLs) were used cautiously in post-refractive patients due to concerns that preexisting or surgically induced higher-order aberrations could degrade visual quality by increasing glare and halos, while also reducing contrast sensitivity. Patients with prior corneal refractive procedures (LASIK, PRK, SMILE, or RK) often have altered corneal curvature, making IOL power calculations and lens performance less predictable. With advances in biometry, corneal imaging, and modern IOL designs that compensate for spherical aberrations, these concerns have diminished. This retrospective cross-sectional study evaluated visual and patient satisfaction outcomes after premium IOL implantation in post-refractive eyes undergoing refractive lens exchange …

Transition To Noninvasive Testing From The Gold Standard Of Liver Biopsy, Heidi Bien, Sabina Choudhry, Christine Pocha, University Of South Dakota Sanford School Of Medicine & Avera Health System

Scholarship Pathways Program

Purpose: Metabolic dysfunction–associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease, represents a rapidly growing public health concern, affecting roughly 30% of the global population. MASLD encompasses a spectrum from simple steatosis to its more progressive form, metabolic dysfunction–associated steatohepatitis (MASH). Early and accurate assessment of liver disease is critical for risk stratification and management, yet the current gold standard-liver biopsy remains invasive, costly, and limited by sampling variability and interpretive subjectivity. Noninvasive imaging modalities, particularly magnetic resonance elastography (MRE), have emerged as promising alternatives, but their concordance with biopsy in real-world clinical practice remains underexplored.

Honors Theses

The Mississippi Gulf Coast is an important resource for transportation, economic development, and recreation. Given its economic and cultural importance, it is crucial to maintain clean and safe conditions along the coast for public health, but other than routine beach monitoring, few studies have examined microbial contamination of coastal waters in this region. This study aimed to determine the quantity, composition, and distribution of bacteria resistant to six different antibiotics (Vancomycin, Kanamycin, Tetracycline, Ciprofloxacin, Erythromycin, or Amoxicillin) in seawater at seven public beaches along the Mississippi Gulf Coast. No bacteria resistant to Ciprofloxacin were detected, and bacteria resistant to Kanamycin …

Lifestyle And Activity Patterns Of The Classic Period Maya From Chac Balam And San Juan, Ambergris Caye, Belize, Abigail L. Hornbeck

Honors Theses

Bioarchaeological research often uses skeletal remains to reconstruct patterns of activity and labor in past populations. This study examines potential sex-based differences in long bone morphology among individuals from the Classic Maya sites of Chac Balam and San Juan on Ambergris Caye, Belize. These coastal communities participated in maritime trade networks, and daily activities such as cargo transport, canoe travel, and fishing may have placed distinctive mechanical stresses on the skeleton. The goal of this study was to evaluate whether measurable differences in bone structure between males and females reflect differences in habitual activity patterns.

Two complementary methods were used …

Head Acceleration Events in Collegiate Rodeo Athletes

Colton Carlson, MS4

Mentor: Thayne Munce, PhD

Introduction: Brain health has been a growing concern across a wide range of contact sports in the last three decades. While most of the early brain health research was focused on identifying and preventing concussions, newer research has found that an accumulation of repetitive head impacts (RHI) is more predictive of long-term brain health than the number of concussions sustained. Consequently, being able to assess RHI in sports despite the lack of outward symptoms has become paramount in promoting the long-term health of athletes. While the …

Addressing Vaccine Hesitancy with Patient Education

Belle Grady, MD | Mentor: Victor Huber, PhD

Background: Vaccine hesitancy is a complex global issue, exacerbated by pandemics and social media. In addition to hesitancy, state policies loosening childhood vaccine requirements and alternative vaccination schedules may contribute to recent vaccine-preventable illness outbreaks in the United States. In South Dakota alone, kindergarten vaccination rates have gradually declined over the past decade. Such vaccine hesitancy and decreasing vaccination rates is a public health concern and must be addressed. Accessible patient education resources on the topic are necessary to increase vaccination rates.
