Background:
Creutzfeldt-Jakob Disease is a rare, progressive neurodegenerative disease caused by the accumulation of prions and is typically fatal within 6-12 months of onset. MRI of the brain is a crucial part of the diagnostic process, evaluating for disease mimics including tumors, infections, and other neuroinflammatory conditions. A literature search of MRI findings in CJD was performed. Characteristic MRI findings include cortical and basal ganglia hyperintensities on FLAIR and DWI. Contrast-enhancing lesions have not been associated with CJD, prompting evaluation for alternative diagnoses.

Case Presentation:
We present the case of a 77-year-old woman who initially presented to her primary care physician with several months of memory loss and unsteady gait. MRI of the brain showed left temporal lobe FLAIR hyperintensity, suggestive of an underlying neoplastic process. She was lost to follow up, then presented to the hospital two months later with acute altered mental status. Her exam was notable for global aphasia, unresponsiveness, and lack of movement. MRI demonstrated new diffusion restriction in the cortex and left dorsal thalamus, along with a new contrast enhancing lesion in the left temporal lobe. Initial cerebrospinal fluid (CSF) testing showed elevated protein with normal white blood cell count. She received empiric IV methylprednisolone and IVIG for presumed inflammatory etiology, without clinical response. Later CSF testing returned positive for real time quaking-induced conversion (RT-QuIC) and 14-3-3 protein, consistent with CJD. She passed away after discharge.

Discussion:
To the authors’ knowledge, this is the first reported case to demonstrate that contrast-enhancing lesions may be seen with CJD, a neurodegenerative disease with poor prognosis. Therefore, it is critical for clinicians not to exclude CJD in the differential diagnosis of a patient with rapidly progressive neurologic decline with contrast-enhancing lesions, in addition to more characteristic imaging findings. This allows for earlier directed testing, including CSF studies, leading to an earlier probable diagnosis, prioritization of comfort care, and minimization of further unnecessary testing.

Objective: This study aims to evaluate recent literature on cancer vaccines, focusing on emerging strategies and advancements in vaccine development. With increasing interest in immunotherapy, novel vaccine delivery mechanisms may enhance efficacy and broaden therapeutic applications.

Methods: A comprehensive literature review analyzing published studies and clinical trial data on cancer vaccines was conducted. Research articles detailing vaccine formulations, immune response mechanisms, and clinical outcomes were included. Particular attention was given to novel approaches, such as nanoparticle-based vaccine delivery.

Results: Recent findings highlight the incorporation of nanoparticles as a promising strategy for cancer vaccine delivery. Nanoparticles enhance antigen presentation, improve immune activation, and enable targeted delivery to tumor-associated antigen-presenting cells. Clinical trials have demonstrated improved vaccine stability and efficacy through nanoparticle-based formulations, suggesting potential advantages over conventional vaccine platforms.

Conclusions: The application of nanoparticle technology in cancer vaccines represents a significant advancement in immunotherapy. These innovations may enhance vaccine efficacy, prolong immune responses, and provide new therapeutic opportunities. Further clinical studies are needed to optimize nanoparticle-based vaccine formulations and assess long-term safety and effectiveness.

Cancer Immunotherapy and Nanoparticles: Enhancing Vaccine Efficacy through Advanced Delivery


The gut microbiome plays a critical role in brain development and function, yet the neural mechanisms underlying microbiome-brain interactions during social processing remain poorly understood. We hypothesized that microbiome depletion fundamentally alters how the brain processes social information across different contexts.


We developed a three-day social context paradigm using FDG-PET neuroimaging in antibiotic-treated (ABX, n=10) and control (CON, n=10) mice. Mice underwent scanning in three contexts: isolation (day 1), familiar social interaction (day 2), and novel social interaction (day 3). Statistical parametric mapping identified brain regions showing significant context-dependent changes in glucose metabolism (p<0.001). ABX mice were administered a broad-spectrum antibiotic cocktail through the drinking water (ampicillin (1 g/L), vancomycin (0.5 g/L), neomycin (1 g/L), and metronidazole (1 g/L) in sterile drinking water), while control mice (CON) received regular drinking water

Microbiome depletion induced distinct context-dependent neural signatures. During transitions from isolation to familiar social contexts, CON mice showed appropriate engagement of social memory circuits (lateral entorhinal cortex, anterior cortical amygdaloid nucleus) with concurrent decreases in primary somatosensory and prelimbic regions. In contrast, ABX mice showed no significant changes between these contexts. When transitioning from isolation to novel social contexts, ABX mice exclusively engaged sensory processing regions (superior colliculus, secondary visual cortex, somatosensory barrel field) without any decreases in regional activity. During familiar-to-novel social transitions, ABX mice further increased sensory processing (visual cortex, somatosensory barrel field), while CON mice showed appropriate motor engagement and decreased somatosensory activity. Notably, ABX mice showed no decreases in neural activity during any context transition.


Microbiome depletion fundamentally alters context-dependent neural processing during social interaction, causing a shift from social memory circuits to compensatory sensory processing. This suggests microbiome-depleted animals maintain social functioning through alternative neural strategies that rely heavily on sensory information rather than appropriate social memory engagement. The absence of neural inhibition during context transitions in microbiome-depleted mice reveals a previously unrecognized mechanism by which microbiome alterations may contribute to social processing deficits in neurodevelopmental and psychiatric conditions.

Background
Human Respiratory Syncytial Virus (hRSV) is a leading cause of lower respiratory tract infections, particularly affecting infants, older adults, and immunocompromised individuals. The virus exists as two major types, RSV A and RSV B, each with distinct clades that aid in tracking viral evolution. Outbreak timing and severity can differ even within nearby areas, and genetic similarities are often seen across neighboring regions. Ongoing viral evolution poses challenges to long-term vaccine development, underscoring the need for localized genomic surveillance to guide public health efforts. This study analyzed hRSV-positive cases from the Emory Healthcare Microbiology Lab to identify mutations that may impact viral fitness and antigenicity. We summarized the genomic evolution of hRSV during the 2024–2025 season at Emory University Hospital and demonstrated how integrating genomic and clinical data can enhance our understanding of viral adaptation, informing both treatment and vaccine development.

Methods
Residual nasal swabs were collected from 182 hRSV-positive adult patients at Emory University Hospital between September 2024 and March 2025. Nucleic acids were extracted, reverse-transcribed to cDNA, and used to generate multiplex RSV amplicon libraries, which were sequenced using Illumina MiSeq or NextSeq platforms (~2 million reads per sample). Genomes were aligned with MAFFT, clades assigned using Nextclade, and mutations analyzed to track potential immune escape variants.

Results

Among RSV A samples, clades A.D.3.1, A.D.5.2, and A.D.1.5 were most prevalent, while RSV B samples were primarily B.D.E.1, with additional cases of B.D.4.1.1 and B.D.E.1.4. In vaccinated individuals (n = 17), infections involved a genetically diverse mix of strains, with B.D.E.1 (24%), B.D.4.1.1 (18%), and A.D.3.1 (12%) being the most common. No single clade predominated among breakthrough infections. Symptom profiles appeared similar between vaccinated and unvaccinated individuals, with the most notable difference being mortality, which was observed only in unvaccinated patients.

Conclusion
Our analysis revealed that multiple RSV A and B clades co-circulated during the 2024–2025 season, demonstrating substantial viral diversity across the region. Breakthrough infections among vaccinated individuals were linked to a wide range of clades, with no evidence of a single dominant escape variant. While our findings align with broader regional trends, we also identified distinct local variants, reinforcing the importance of continued, localized genomic surveillance. The study was limited by sample size and scope, highlighting the need for expanded surveillance efforts. Ongoing analyses using Nextclade will focus on identifying prevalent escape mutations driving immune evasion. This genetic diversity in both vaccinated and unvaccinated individuals emphasizes the evolving nature of RSV and the need for adaptive public health strategies and vaccine design.

Abstract Title:
Another Subconjunctival Hemorrhage? Unraveling an Unusual Ocular Surface Lesion

Background:
Kaposi’s sarcoma (KS) is a vascular neoplasm associated with immunosuppression, particularly advanced HIV with human herpesvirus 8 (HHV-8) coinfection. Classic presentation includes violaceous, cutaneous and/or mucosal lesions in the setting of a diminished CD4 count; however, reports have also described extracutaneous disease involving visceral organs, and more rarely, ocular structures such as the conjunctiva. We describe herein a rare case of conjunctival KS presenting near the time of initial HIV diagnosis and erroneously regarded as a subconjunctival hemorrhage.

Case Presentation:
A 38-year-old man with newly diagnosed HIV (CD4 18) and a history of oral thrush, cutaneous KS, and recently treated hospital-acquired pneumonia presented to our emergency department with a chief complaint of dyspnea on exertion. He was initially presumed to have a subconjunctival hemorrhage of his right eye, which he reported to have first developed as a red lesion 3 months prior. A subsequent slit-lamp examination in our outpatient ophthalmology clinic unearthed suspicions for a clinical diagnosis of conjunctival KS in addition to HIV retinopathy. An ensuing conjunctival biopsy identified a vascular mass in the substantia propria with positive HHV-8 immunohistochemical staining, confirming the diagnosis of KS. Shortly thereafter, the patient deteriorated clinically and eventually succumbed to complications of advanced HIV, despite initiation of antiretroviral therapy (ART) and linkage to our oncology service for outpatient chemotherapy.

Discussion:
In the era of ART, ocular KS is rare, although not unprecedented due to ART failure, medication nonadherence, or delayed HIV diagnosis influenced by an array of socioeconomic determinants. This case represents the interdisciplinary nature of treating advanced HIV and the importance of recognizing its unconventional ocular manifestations; furthermore, ocular KS can present as a deceptive entity mimicking common clinical findings and appearing as a harbinger of a poor prognosis.

Abstract Title:
Language Matters: Assessing the Role of Interpreter Access in Patient Satisfaction
Background
The United States (U.S) is home to a large and growing immigrant population, with the number
of immigrants reaching 47.8 million in 20231. A 2011 study reported that over 55 million
individuals in the U.S.—both immigrant and U.S.-born—speak a non-English language at home,
with 8.6% considered to have limited English proficiency (LEP)2. LEP may lead to language
barriers which can hinder clear communication between patients and healthcare providers, often
resulting in confusion and dissatisfaction with care. Addressing these barriers is crucial to
enhancing the overall patient experience. The use of trained medical interpreters has been
associated with improved patient satisfaction and communication among LEP individuals2,3,4.
This study aims to evaluate the impact of interpreter services on patient satisfaction among
individuals with LEP in healthcare settings.
Methods
A systematic literature search for peer-reviewed English articles was conducted in PubMed.
Three independent researchers assessed journal eligibility based on publication date,
relevance, and study quality. The search utilized the keywords “interpreter efficiency,”
“healthcare access,” “language barriers,” and “patient satisfaction,” and was limited to
publications from 2000 to 2024, yielding four articles included in this study. The US Census was
used for information on immigration trends.
Results
Current data shows that using trained interpreters increases LEP patients’ satisfaction and trust,
understanding of their medical care, and improves patient outcomes. In contrast, ad hoc
interpreters, such as family members or untrained staff, more frequently lead to clinical
misunderstandings and breaches of confidentiality2,3,4. LEP patients also prefer in-person over
telephone or video interpreters, especially for more sensitive or complex discussions; this builds
better patient-physician rapport and connection5.
However, access to in-person interpreters is inconsistent across different healthcare settings4.
Several studies highlight the need to improve remote interpretation by expanding language
options and prioritizing video formats4,5. Additionally, providers reported greater confidence and
fewer errors when working with professional interpreters3.
Conclusion
Expanding access to trained medical interpreters, preferably in-person, and strengthening
remote services can significantly improve patient satisfaction and health outcomes for
individuals with LEP. Ensuring consistent and high-quality language services across all
healthcare settings is essential to reducing communication barriers. Thus, as the LEP patient
population continues to grow in the U.S., strengthening these services is a crucial step towards
the delivery of more equitable and patient-centered care.

Bridging Gaps in Care: Addressing Health Disparities in Colorectal Cancer Screening. 

Jacob Culclasure, M2 student2; Hanna Anhalt, M2 student2; A. Miles Scott, DO1.

Introduction: Colorectal cancer (CRC) is the third most diagnosed cancer and third leading cause of cancer-related death in both men and women in the U.S., with increasing incidence among individuals under 50 years of age. Early screening and detection improve outcomes by identifying cancers at more treatable stages. Non-adherence to screening guidelines is a major contributor to worse outcomes. Barriers to screening predominantly affect marginalized groups due to remaining systemic injustices. In South Carolina, disparities exceed the national average. 

Methods: An Epic report of patients aged 45-75 seen at FMC Colonial in the past year determined potential factors contributing to CRC screening rates. The report established each patient’s age, insurance status, sex, and race. Pivot tables were produced to describe how each demographic factor contributed to rates of CRC screening and identify areas of intervention. The percentage of patients at goal was calculated by dividing the number of patients up to date on CRC screening by the total number of patients. 

Results: Among 3,397 eligible patients, 57.96% were up to date with recommended screening. Screening rates varied significantly by age group, insurance status, and sex. Only 48.6% of patients aged 45-54 were screened, compared to 59.8% of those 55-64 (p<0.000001) and 65.9% of those 65-75 (p<0.000001). Insurance status was strongly associated with screening. Patients with Medicare (62.2%) and private insurance (60.0%) had significantly higher screening rates compared to those with Medicaid (46.9%) and the uninsured (43.7%). Specifically, Medicaid patients had lower rates than both Medicare (p<0.000001) and private insurance (p<0.00001), and uninsured patients had a lower rate compared to Medicare (p<0.000001) and private insurance (p<0.00001). Differences in screening rates among sexes were less pronounced but still significant, with screening rates higher among females (60.4%) than males (53.9%, p=0.00024). In contrast to existing literature, no significant differences were found between racial groups. 

Conclusion: CRC screening rates in this population were influenced by age, insurance status, and sex, with older, insured, and female patients more likely to be screened. While no statistically significant racial disparities were identified, screening rates were lower among younger adults, males, and uninsured patients. These findings emphasize the need for targeted, clinic-based interventions, such as in-clinic education, counseling on testing options, and connecting patients to state-funded programs to support the uninsured, to improve overall screening rates.

Title: Cybersecurity Literacy Among Clinical Staff: A Simulated Survey Reveals Risk Exposure And Training Gaps In Healthcare Settings
Author: Temitope Adewuyi MB:BS ECFMG Certified 
Background: As healthcare systems undergo rapid digitization, frontline clinical staff are increasingly exposed to cybersecurity threats such as phishing, ransomware, and HIPAA violations. Despite the sensitivity of patient data and the growing frequency of cyberattacks, cybersecurity education remains fragmented and inconsistently integrated into clinical workflows. This study explores the extent of cybersecurity literacy among medical personnel and identifies key vulnerabilities in digital hygiene and procedural awareness.
Methods: A simulated cross-sectional survey was conducted using modeled data from 100 clinical staff, including physicians, nurses, and administrative personnel. The instrument comprised ten structured items assessing familiarity with phishing detection, password hygiene, multi-factor authentication (MFA), HIPAA compliance, incident reporting, and perceptions of cybersecurity responsibility. Data were synthesized from published trends and benchmarked against national healthcare cybersecurity reports.
Results: Only 38% of respondents could accurately identify phishing email traits, while 62% admitted to reusing passwords across multiple systems. Formal cybersecurity training had been received by just 28% in the past year. Knowledge of HIPAA’s cybersecurity clauses was limited to 41%, and only 36% expressed confidence in recognizing spoofed login portals. While 52% reported using MFA, only 33% believed cybersecurity fell within their clinical role. Additionally, 59% had encountered phishing attempts within six months, 46% understood how to report a suspected cyber incident, and 48% used encrypted messaging tools for patient communication.
Conclusion: The simulated findings reveal significant gaps in cybersecurity literacy among clinical staff, with low training rates, poor password practices, and limited procedural awareness. These vulnerabilities pose a direct threat to patient data integrity and institutional resilience. To mitigate risk, healthcare systems must implement mandatory, role-specific cybersecurity education and foster a culture of digital accountability. Strengthening frontline awareness is essential to safeguarding clinical operations in an increasingly connected care environment.

Cybersecurity Literacy Among Clinical Staff

Despite the prevalence of domestic abuse and its profound dermatological impacts, there remains a scarcity of comprehensive research exploring this issue through a cross-cultural lens. The objective of this review was to synthesize available evidence on the dermatological impacts of domestic abuse across cultural contexts. This systematic review was conducted and reported according to PRISMA guidelines. Research studies focusing on individuals who have experienced domestic abuse in various cultural contexts were included. The primary exposure was domestic abuse, and studies investigating its dermatological impacts were eligible for inclusion. Eleven studies were included in the review. Majority of the included studies were observational studies (n=8) while 4 studies were case reports, covering diverse regions including North America, Europe, South America, Asia, and Australia. The majority of participants were female survivors of intimate partner violence (IPV), with mean ages typically falling in the early to mid-30s. The most frequently reported dermatological injuries included bruises and contusions primarily affecting the face, neck, upper and lower limbs, and scalp. Lacerations and incised wounds were reported in multiple studies, followed by abrasions, ecchymosis, burns, scarring and permanent disfigurement. While the types of injuries were largely consistent across geographical settings, some regional patterns were observed. The findings highlight the global burden of dermatological injuries in survivors of domestic abuse. The findings suggest that while patterns of skin injuries are relatively consistent, cultural and regional factors may influence the nature and severity of injuries, warranting further investigation.

Skin and Scars Across Cultures: The Dermatological Impacts of Domestic Abuse - A Systematic Review

Introduction
Preventive services are cornerstones of population health, yet uptake remains suboptimal and inequitable. Health literacy, defined as the capacity to obtain, process, and understand basic health information, is a recognized driver of individual and community health. This study aims to understand the relationship between health literacy and preventive care utilization. Based on prior literature, we used educational attainment and spoken home language as proxies for health literacy in our sample. 
Methods
We analyzed data from the 2023 National Health Interview Survey, identifying adults eligible for five USPSTF-recommended preventive services: colonoscopy, Pap smear, mammography, non-diabetics blood sugar testing, and annual influenza vaccination. Each outcome was modeled via survey-weighted logistic regression, assessing home language (English vs. non-English) and education level as primary predictors. Additionally, a composite metric, defined as receiving at least three of the five preventive care services per USPSTF guidelines, was modeled similarly. All models adjusted for age, race/ethnicity, and insurance coverage.
Results
A total of 21,110 respondents were included in our sample, representing 184.5 million US adults after survey weighting. Lower educational attainment was linked to significantly reduced odds of guideline-concordant screening for pap smears (OR 0.59, 95% CI 0.49-0.72, p<0.001), mammogram (OR 0.62, 95% 0.51-0.77, p<0.001), blood sugar testing (OR 0.64, 95% CI 0.54-0.76, p<0.001), and influenza vaccination (OR 0.47, 95% CI 0.43-0.51, p<0.001), but not colonoscopy. Non-English speakers had significantly lower odds of Pap smear (OR 0.65, 95% CI 0.50-0.85, p<0.001) and blood sugar testing (OR 0.81, 95% CI 0.66-0.99, p<0.04), but not the other services. In our composite model, respondents with lower education had 41% lower odds of obtaining at least three of the five preventive care services (OR 0.59, 95% CI 0.54-0.64, p<0.001), whereas home language was not a significant predictor. 
Discussion
Using education and home language as proxies for health literacy, we identified clear disparities in preventive‐care uptake. Targeted interventions such as expanded language assistance and interpretation services, in addition to culturally sensitive health resources, may aid in closing these gaps in preventive health behaviors.


Bridging Health Literacy Gaps: The Impact of Education and Language on Guideline-Concordant Screening and Vaccination

INTRODUCTION: In surgery, textbook outcomes represent a composite metric of multiple variables that indicate baseline success in a specific procedure. These outcomes can be compared across surgeons and institutions. This study aimed to define a textbook outcome for the operative repair of scaphoid nonunion using medial femoral condyle (MFC) or medial femoral trochlea (MFT) vascularized bone flaps and identify the rate of textbook outcomes at our center.

METHODS: Three hand surgeons with expertise in scaphoid nonunion reconstruction using MFC/MFT grafts defined the criteria for a textbook outcome. After obtaining IRB approval, a retrospective review of cases from 2017 to 2024 at a single institution was performed. A textbook outcome was defined as meeting the following criteria: no flap loss, no intraoperative complications, a length of stay of less than two nights, radiographic union at three months postoperative on CT scan, return to baseline hand activities and pain-free hand activities at final follow-up, return to baseline and pain-free lower extremity activities by postoperative day 90, no recipient or donor site infections requiring intravenous antibiotics, no systemic complications, no emergency room admissions or hospital readmissions within 90 days, no mortality, and no surgical complications requiring reoperation.

RESULTS: A total of 38 patients met the inclusion criteria, with 27 (71.1%) achieving a textbook outcome. The most common criteria not met were surgical complications requiring reoperation (10.5%), return to baseline hand activities at final follow-up (7.9%), pain-free hand activities at final follow-up (7.9%), and return to baseline lower extremity activities by postoperative day 90 (7.9%). Of the 11 cases that did not achieve a textbook outcome, 5 violated one criterion (45.4%), 3 violated two criteria (27.3%), and 3 violated more than two criteria (27.3%).

CONCLUSION: Textbook outcomes are useful quality metrics for evaluating surgical success. By utilizing 13 criteria for scaphoid nonunion reconstruction with vascularized MFC or MFT grafts, cases can be assessed and compared using a single metric. Statistical analysis can help identify predictors of textbook outcomes, offering future opportunities to improve patient outcomes.
