Bergmann glia (BG) are a specialized glial population essential for cerebellar development, yet their developmental timeline and molecular identity in the human cerebellum remain poorly understood. Here, we combined detailed histopathological analysis with spatial transcriptomics and single-nucleus RNA sequencing to generate a developmental atlas of human cerebellar BG. Histology revealed that BG emerge around 11 post-conception weeks (PCW), initially serving as a scaffold for Purkinje cells (PCs) migrating into the PC layer of the cerebellar cortex. Following the establishment of a multilayered PC arrangement, BG form a distinct parallel layer separated from the PCs by the lamina dissecans (LD), with …

When Nutrition Fails: Modeling Protein Malnutrition-Driven Vulnerability In Hepatic Drug Metabolism And Inflammatory Stress, Vijitha D. Kantety, Victor Jiminez Jr.

Annual Research Symposium

Background

Protein malnutrition remains a major global health problem and frequently co-occurs with alcohol use, opioid exposure, and infectious disease, particularly in low- and middle-income settings. The liver is central to both metabolism and inflammatory regulation, yet the effects of a malnutrition-like nutrient environment on hepatic responses to combined metabolic and inflammatory insults are not well defined. Cytochrome P450 3A4 (CYP3A4), a key enzyme involved in opioid metabolism, is highly sensitive to inflammatory signaling and may be especially vulnerable under conditions of nutritional deficiency. This project aims to 1) develop an in vitro model of nutritionally competent versus amino acid–restricted …

Metastatic Castrate-Resistant Prostate Cancer To The Penis Resulting In Malignant Priapism And Urethral Obstruction, Courtney Stewart, Joon Yau Leong, William Kevin Kelly, Mihir Shah

Department of Urology Faculty Papers

A 76-year-old male with metastatic castrate-resistant prostate cancer was found to have metastatic disease to the urethra and penis on PSMA PET scan. This resulted in constant pain due to obstruction of blood flow through the corpora cavernosum resulting in priapism and urethral obstruction. The patient underwent a radical penectomy, partial urethrectomy and perineal urethrostomy creation. Final pathology confirmed metastatic prostatic adenocarcinoma. Although rare, prostate cancer can metastasize to the corpora spongiosum or cavernosa. Treatment options are limited, and surgical excision with urinary diversion is likely to provide the most durable outcomes for one's quality of life.

Could Dietary Zinc Protect Your Gums? Insights From Non-Diabetic Adults, Jacob R. Kelly, Hayden Dehoyos, Man Hung Phd, Amir Mohajeri Phd

Conclusion:
These findings suggest that sufficient zinc intake may …

Quality Improvement Project: Enhancing Nurse Communication, Courtesy, And Respect At The Bedside, Rachel Kemp

Doctor of Nursing Practice Projects

Effective communication is key to the nurse-to-patient relationship, patient outcomes, and patient satisfaction. The literature widely shows that barriers such as increased workplace violence and fear and biases within patient interactions hinder communication. This quality improvement project aimed to enhance nurse-to-patient communication, using an evidence-based tool, and leveraged Foli’s Theory of Nurses’ Psychological Trauma to explain and predict barriers. Success is measured by improvement of patient experience in the three nursing domains; courtesy and respect, listen to you, and explain in a way you understand. Lewin’s Change Theory and the plan, do, study, act (PDSA) framework was used to promote …

Quality Improvement Project: Implementation Of The Surgical Safety Checklist To Improve Adherence To Time-Out At In-Office Procedure, Funke Osaremwinda

Doctor of Nursing Practice Projects

Surgical errors in ambulatory and in-office procedural settings continue to rise despite well-established safety standards, such as the time-out (TO) protocol. Literature consistently links non-adherence to the TO protocol to preventable events such as wrong patient, wrong site, or wrong surgery. At the cardiovascular ambulatory clinic where the quality improvement (QI) project was implemented, the baseline needs assessment indicated inconsistent TO practices and the absence of a standardized tool to support TO. The purpose of this project was to improve adherence to the TO safety protocol through staff education and implementation of the evidence-based World Health Organization (WHO) Surgical Safety …

Quality Improvement Project: The Impact Of Hypertension Management Education In Primary Care, Toyin K. Aliu

Doctor of Nursing Practice Projects

Hypertension (HTN) is one of the leading causes of clinic visits and prescription medication use in primary care settings. Despite the availability of evidence-based guidelines to improve HTN management, adherence in clinical practice is often lacking. At the project site, 30% of patients have uncontrolled HTN. This is attributed to providers’ inadequate knowledge of the JNC-8 HTN management guidelines and inconsistent adherence to them. This project aimed to improve hypertension management in a primary care setting by educating providers on the JNC-8 guidelines to enhance adherence to evidence-based practices over six weeks. The purpose was to align medical providers with …

Improving Benzodiazepine Refill Workflow And Communication Via Telehealth Using A Standardized Sbar Protocol, Hendricks Agwu

Doctor of Nursing Practice Projects

The development in telehealth operations in outpatient mental health care has enhanced access to care at the expense of creating challenges in communication and workflow, especially when it comes to dealing with high-risk substances like benzodiazepines. The role ambiguity, inaccurate refill timeline, documentation lapses and high chances of medication errors are caused by inconsistent communication during the process of telehealth refills. This quality improvement project was aimed at assessing the effects of applying a standardized Situation, Background, Assessment, Recommendation (SBAR) communication and documentation protocol to workflow efficiency, interprofessional communication, and medication safety when making benzodiazepine refills in a telehealth outpatient …

Non-Canonical Role Of Dna Mismatch Repair On Sensory Processing In Mice, Sadia N Rahman, Demetrios Neophytou, Siboney Oviedo-Gray, Bao Q Vuong, Hysell V Oviedo

2020-Current year OA Pubs

DNA repair mechanisms are essential for cellular development and function. In post-mitotic neurons, deficiencies in DNA damage response proteins can lead to severe neurodegenerative and neurodevelopmental disorders. One highly conserved factor involved in DNA repair is MutS Homolog 2 (Msh2), which is responsible for correcting base-base mismatches and insertion/deletion loops during cell proliferation. However, its role in mature neurons remains poorly understood. This study investigates the impact of Msh2 loss on sensory processing in mice. Using electrophysiological and molecular assays, we identifiedsignificant deficits in cortical and thalamic sound processing in Msh2

Relationship Between Navigation Success, Diagnostic Accuracy, And Ventilation Strategy: Retrospective Chart Review Of 224 Consecutive Navigational Bronchoscopic Procedures Performed Under General Anesthesia, Basavana Goudra, Prarthna Chandar, Divakara Gouda, Harrison Yang, Ganan Muhunthan, Suvan Sundaresh, Michael Stuart Green

Department of Medicine Faculty Papers

Background: Navigational bronchoscopy (NB) enables precise sampling of peripheral and central pulmonary nodules using shape-sensing or electromagnetic guidance. A major challenge is anesthesia-induced atelectasis, which alters lung anatomy, reduces registration accuracy, and is known to lower diagnostic accuracy. To counteract this, ventilatory protocols such as the Ventilatory Strategy to Prevent Atelectasis (VESPA) and the Lung Navigation Ventilation Protocol (LNVP) have been recommended. Their adoption and clinical impact, however, remain uncertain. Methods: We conducted a retrospective review of 224 consecutive NB procedures performed under general anesthesia at a single academic medical center (January 2020–August 2024). Demographic, anesthetic, and ventilatory data were …

Radiation therapy (RT) is the standard of care for glioblastoma but is not curative. Triggering the cGAS/stimulator of interferon genes (STING) pathway with potent agonists, such as 8803, exerts activity across high-grade glioma preclinical models. To determine if the combination of 8803 with RT warrants consideration in the up-front treatment setting and to clarify the underlying mechanisms of therapeutic activity, C57BL/6J mice harboring intracerebral CT-2A or QPP8v gliomas were treated with RT, intratumoral 8803, or both. The treatment with the combination resulted in 80% long-term survival in the CT-2A model but not in the radiation-resistant QPP8v model. This therapeutic effect …

Mutant Kras In Brain Endothelial Cells Promotes Vascular Inflammation And Impairs Vascular Integrity In Brain Arteriovenous Malformation, Jung-Eun Park, Bridger H Freeman, Hyejin Park, Sehee Kim, Adrian E Bafor, Ohnmar Myint, Song Gao, Zhen Xu, Jakob Körbelin, Jaroslaw Aronowski, Peng Roc Chen, Eunhee Kim, Eun S Park

Faculty, Staff and Student Publications

Somatic KRAS (KRASG12V) mutation in endothelial cells (EC) induces brain arteriovenous malformation (bAVM) that could lead to vascular instability and ultimately bleeding. However, the causes of bAVM instability remain unclear. Here we demonstrate that KRASG12V expressing cultured ECs (KRAS-G12V-EC) have increased expression of pro-inflammatory mediators and reduced expression of blood-brain-barrier (BBB) junction constituents. The conditioned medium from KRAS-G12V-EC can activate BV2-microglia (BV2-MG) and conditioned media from this primed BV2-MG can compromise the expression of EC-junction constituents when added to wild-type ECs. In an in vitro BBB model, KRAS-G12V-EC form a dysfunctional EC barrier that is further disrupted, leading to lower …
