Eastern Virginia Medical Journal

In this report, we discuss the case of a patient with Listeria monocytogenes bacteremia likely resulting from primary biliary cholangitis (PBC) induced cirrhosis. We aim to bolster the body of literature on Listeria bacteremia and establish PBC as a risk factor for this rare complication. Our patient, who presented with sepsis, was subsequently found to have Listeria bacteremia and received intravenous antibiotic treatment of ampicillin for 3 total weeks with complete resolution of her disease. This is the first case suggesting that cirrhosis as a result of PBC may be an independent risk factor for Listeria bacteremia. In patients at …

“No Ifs, Ands, Or Butts”: Analyzing Race And Gender In Sex And The City Through Black Feminist Theory, Daniella Orias

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

This article analyzes Season 3, Episode 5 of Sex and the City, “No Ifs, Ands, or Butts,” through the lens of Black feminist theory. It investigates how race and gender are constructed, stereotyped, and selectively represented within the episode’s narrative. The analysis focuses on two Black characters who were featured only in one episode of the series, Adeena and Chivon, and examines how the show portrays harmful stereotypes such as the angry Black woman (Adeena) and sexualized Black male (Chivon) in the episode. These limited and harmful representations are further scrutinized by the fact that the show is often …

Existence Of Traveling Waves Of Lotka Volterra Type Models With Delayed Diffusion Term And Partial Quasimonotonicity, William Barker

Faculty Scholarship

This paper investigates the existence of traveling wave solutions for diffusive two-species Lotka–Volterra systems with delays in both the reaction and diffusion terms under partial monotonicity assumptions. The model incorporates small-memory effects in the homo- geneous diffusion term, representing a modification of the random-walk interpretation underlying Fick’s law. We extend the partial (cross) monotone iteration method to systems satisfying a partial quasi-monotone condition through the construction of appropriate upper and lower solutions. Convergence of the iteration is established using Schauder’s fixed point theorem.

Perception As Beholding: Theological Possibility And Moral Implication Of Merleau-Ponty's Notion Of Embodied Subject, Erickson L. Totanes

Budhi: A Journal of Ideas and Culture

In this article, I argue that Merleau -Ponty’s concept of perception reveals a way of seeing where the subject is involved with the object in a dynamic, reversible, and expanding relationship. This notion challenges the traditional and Cartesian subject -object dichotomy by emphasizing the embodied and lived experience of perception which elicits a process, a way of looking, anticipating, and reflexively, a way of being itself. By aligning seeing with beholding, I attempt to show how as simple an act as seein g evokes a manner of being related to an object, other people, and the world. The emergence of …

Circulating Tumor Dna: Reducing Burden In Hpv+ Oropharyngeal Cancer Surveillance, Liza M. Joseph Pa-C

Lynchburg Journal of Medical Science

This review examines the rising prevalence of human papillomavirus-related (HPV+) oropharyngeal squamous cell carcinoma (OPSCC) and evaluates the role of circulating tumor HPV DNA (ctHPVDNA) in diagnosis and post-treatment surveillance. A comprehensive literature search of electronic databases, including PubMed, Medline, Cochrane Library, and Google Scholar, identified studies that validated ctHPVDNA as a biomarker with high sensitivity and specificity, assessed its cost-effectiveness, and explored patient and provider perceptions.

Wilderness Therapy As An Intervention For Teens Who Are At The End Of Their Rope, Blake C. Neal, Heather Summers

Lynchburg Journal of Medical Science

Abstract

Wilderness therapy, treatment offered in a natural setting, is offered as an alternative to traditional treatment methods (Lodato, N., Blivas, R., & Blivas, N. L. and R., 2024). This model is often used as a last resort for teens who are unsuccessful in other environments. However, when used as a blanket treatment model for all mental health concerns, there is a risk for greater harm inflicted on participants. A case study approach provides evidence of a teen in one of these settings struggling with an eating disorder and self-harm. Although potentially helpful with some concerns, we learn from this …

Subcutaneous Insulin Use In Diabetic Ketoacidosis, Patrick Mcgrath

Lynchburg Journal of Medical Science

The reviewed literature focuses on the clinical application of subcutaneous (SQ) insulin, particularly rapid-acting insulin analogs (RAIAs), in treating selected patients with mild to moderate diabetic ketoacidosis (DKA). The use of SQ insulin offers a viable alternative to traditional intravenous (IV) insulin infusions, enabling DKA management outside intensive care unit (ICU) settings and reducing healthcare resource utilization. Current DKA management protocols emphasize comprehensive fluid resuscitation and correction of electrolyte imbalances, with IV regular insulin administered at 0.1 units/kg/hour. This review synthesizes findings from multicenter cohort studies, meta-analyses, and randomized controlled trials (RCTs) available via PubMed, focusing on adult patients diagnosed …

Brief Overview Of Assessment And Prognostication Tools For Palliative Care Oncology Patients, Nicole Schwensow

Lynchburg Journal of Medical Science

Patients with life-threatening illnesses can be at risk for the progression of their disease over time. Consequences of such an illness can include recurrent hospitalizations, poor symptom control, and a lack of understanding by the patient and family of the disease, its usual course, and prognosis. Palliative care is a philosophy of care intended to address these issues. While receiving palliative care, patients can continue to undergo treatments directed at a cure, whereas hospice patients no longer receive treatment for underlying diseases. Both approaches focus on symptom control. To best care for palliative patients over time, several outcome domains should …

Management Of Difficult Patient Situations, Sangeetha Larsen Mpas, Pa-C

Lynchburg Journal of Medical Science

The purpose of this paper is to provide strategies for clinicians to manage difficult patient interactions. A comprehensive search of PubMed was conducted, identifying articles that identified the root cause of difficult patient interactions and assessed methods for successfully navigating these situations. The term “difficult patient” reflects the interaction of patient behavior, clinician perception, and systemic constraints rather than an inherent patient flaw. Effective management involves reframing difficult behavior as an expression of unmet needs and responding with empathy, active listening, clear boundaries, and collaborative decision-making. System-level strategies reduce patient distress and clinician burnout. Ultimately, the difficult patient represents strained …

Semi-structured interviews with five Midwestern undergraduate women (n = 5) explored perceptions of visibility, ease of use, barriers, and improvement ideas. Transcripts were analyzed using reflexive thematic analysis. Themes included confusion about entry pathways, visibility-related stigma, and the salience of faculty/peer bridges to services. Students generally preferred integrated models, citing privacy through co-location, normalization, and easier warm handoffs; some noted that standalone centers can feel more specialized yet risk heightened visibility depending on location. Findings …

Reclaiming My Story: A Freirean Framework For Surviving Trauma And Transforming Recovery Into Liberation, Carl Bryan

The Interactive Journal of Global Leadership and Learning

This white paper explores trauma recovery through the lens of Paulo Freire’s Pedagogy of the Oppressed (1970/2018), framing healing as an act of critical consciousness and liberation rather than passive survival. Using the author’s lived experience of stalking, manipulation, and emotional abuse as a case study, it reimagines recovery not as a return to normalcy but as a dialectical process of reclaiming narrative agency, reconstructing identity, and transforming pain into purpose. Drawing upon Freirean concepts of conscientização (critical consciousness), dialogue, and praxis, the paper outlines a model for survivors to move from internalized oppression toward empowerment and social transformation.
