Exploring The Impact Of University-Recognized Spaces On Racial Battle Fatigue Among Black Faculty & Staff At Historically White Institutions, Tiffany M. Courseault

LSU New Orleans Theses and Dissertations

Black Faculty and Staff (BFS) at Historically White Institutions (HWIs) navigate environments shaped by racial microaggressions, systemic inequities, and institutional marginalization. These conditions contribute to Racial Battle Fatigue (RBF), a psychological, behavioral, and physiological response to sustained exposure to racialized stress. While institutional Diversity, Equity, and Inclusion (DEI) initiatives are often positioned as mechanisms for improving campus climate, existing research suggests they frequently fail to address the lived realities of BFS. This study examined how university-recognized communal spaces function as critical sites of support, resistance, and mitigation within these environments.

Using a narrative inquiry methodology, this study explored the lived …

Faculty, Staff and Students Publications

Childhood obesity is rising and leading to serious co-morbidities, among which is metabolic dysfunction-associated steatotic liver disease (MASLD) predisposing individuals to cirrhosis. We describe a young 11-year-old Hispanic male who presented with hepatopulmonary syndrome secondary to cirrhotic portal hypertension from metabolic dysfunction-associated steatohepatitis (MASH), necessitating liver transplantation. Despite lifestyle modifications post-transplantation, the patient experienced persistent weight gain and recurrence of steatosis, emphasizing challenges of managing pediatric MASLD. The burden of childhood obesity is increasing and impacting children significantly earlier than previously believed. Our case is one of the few to report the severe complications of MASH in a young, pre-teen …

This scoping review explored the roles of the allied health professions in falls prevention screening, assessment and intervention for community-dwelling older adults. Design: Scoping review, using the Joanna Briggs Institute methodology for scoping reviews. Data sources: PubMed, CINAHL, Scopus, Cochrane, Web of Science …

Medical Simulation In Toxicology: Enhancing Clinical Competence, Decision Making And Patient Care In Resource-Limited Settings, Rakesh Ghimire, Anjana Thapa, Sanjeev Kharel, Shristi Kharel Ghimire, Rabin Basnet, Farshad Mazda Shirazi, Allan J. Hamilton

Research outputs 2022 to 2026

Medical simulation has emerged as a transformative approach in toxicology education. By providing immersive, hands-on experience, simulation enhances learner engagement, critical thinking, and long-term knowledge retention while offering a safe environment to practice clinical decision-making without jeopardizing patient safety. Despite these advantages, the integration of simulation-based training remains limited in low-and middle-income countries (LMICs) due to resource constraints, lack of standardized curricula, and limited access to high-fidelity simulators. Additionally, little research has explored its optimal application in these settings. This review explores available evidence regarding the effectiveness of medical simulation in the diagnosis and treatment of toxicological emergencies in LMICs. …

Gender Disparities Among General Surgeons: A Comprehensive Review, Julie Holihan, Devi Bavishi, Kush Brahmbhatt, Rebecca Franks, Zuhair Ali, Karla Bernardi, Christine Castillo, Mike Liang, Rachel Wong, Michele Loor

Faculty, Staff and Student Publications

Background: Unlike in-house call, the Accreditation Council for Graduate Medical Education (ACGME) does not require a postcall day for "home call" shifts. Despite this, we hypothesize that on-call residents are still in the hospital for the majority of their shift despite having the luxury of home call and, thus, are not protected by ACGME postcall duty hour regulations.

Methods: A prospective single center survey study was conducted by surveying junior and senior residents who completed overnight call shifts from January 2023 to April 2023 at one of the busiest level 1 trauma centers in the United States. Data include number …

MRI studies in bipolar disorder (BD) have yielded inconsistent findings, partly due to the varied use of psychotropic medications. This study utilised a mega-analysis approach, accounting for concurrent medication status (syndrome-based and Neuroscience-based Nomenclature (NbN) classifications), in order to assess the association of medication status with subcortical brain volumes in BD. Data from 2,664 BD patients and 4,065 controls (CN) were pooled from 34 research groups as part of the ENIGMA Bipolar Disorder Working Group. Standardized ENIGMA protocols were used to measure subcortical brain volumes. Linear-mixed-effects regression evaluated the association between psychotropic medications and subcortical volumes, and moderation analyses explored …

Intravenous Buprenorphine Reversed Opioid-Induced Respiratory Depression Without Precipitating Withdrawal In Emergency Department Patients, Anthony Spadaro, Nicholas Imperato, Jaclyn Scalgione, Cynthia Santos

Faculty, Staff and Student Publications

Objective: Buprenorphine is a high-affinity partial agonist that can displace full opioid agonists and could be used to reverse opioid-induced respiratory depression. There is scant evidence to support the use of buprenorphine in an acute opioid overdose to reverse respiratory depression in the era of high fentanyl prevalence in the drug supply. This is a case series of four patients with signs and symptoms of an opioid overdose who showed clinical improvement after receiving intravenous buprenorphine.

Method: A case series of adult emergency department patients treated at a single urban academic medical center was reviewed by the authors, who determined …

Neuroanatomical findings on panic disorder (PD) are typically difficult to replicate, with inconsistent effects. These concerns prompted a paradigm shift towards large-scale collaborations, focused on harmonized data extraction and processing for robust examination of PD brain correlates. Hence, leveraging the largest-ever multi-site neuroimaging database on PD (Age: 10–66 years; global sites: 28), compiled by the ENIGMA-Anxiety Working Group, we report on cortical and subcortical differences in individuals with PD (N = 1146) versus healthy controls (HC: N = 3778). The analyses revealed lower thickness and smaller cortical surface area within fronto-temporo-parietal regions in PD (Cohen’s ds: −0.08–0.13), along with lower …

Crispr-Cas9 Cd33-Deleted Allogeneic Hematopoietic Cell Transplantation With Gemtuzumab Ozogamicin Maintenance In Aml: A Phase 1/2 Trial, John F Dipersio, Et Al.

2020-Current year OA Pubs

Patients with high-risk acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) are likely to relapse despite allogenic hematopoietic cell transplantation (HCT). Post-HCT preventative maintenance can be limited by toxicity toward the normal donor cells. Tremtelectogene empogeditemcel (trem-cel) is a CRISPR-Cas9 gene-edited allogeneic HCT product lacking CD33, designed to shield the donor graft from cytotoxicity of subsequent CD33-targeted therapies such as gemtuzumab ozogamicin (GO). In this multicenter, phase 1/2a, open-label study, adult patients with AML/MDS with high relapse risk received trem-cel after myeloablative conditioning followed by GO maintenance (0.5-2.0 mg m

Primary Cilia Regulate Glp-1 Signaling In Pancreatic Β Cells, Isabella Melena, Jeong Hun Jo, Shannon E Townsend, Samantha Adamson Digruccio, Xinhang Dong, Lifei Zhu, Jonathan Campbell, Jing W Hughes

2020-Current year OA Pubs

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are mainstay therapies for diabetes and obesity, acting in part by enhancing glucose-dependent insulin secretion. While the primary cilium is a known signaling compartment for certain G-protein coupled receptors (GPCRs), its role in the β-cell response to incretins remains undefined. Here, we show that primary cilia are essential for full GLP-1R signaling. Loss of β-cell cilia in mouse and human islets severely impaired GLP-1-potentiated insulin secretion, an effect preceded by blunted whole-cell cAMP and Ca

2020-Current year OA Pubs

Nusinersen, an antisense oligonucleotide, modulates pre-mRNA splicing to produce full length survival motor neuron protein in spinal muscular atrophy (SMA). It was approved in the US for SMA in all ages based on evidence in children. In adults, studies of nusinersen rely on real-world observational data and show stability or small improvements over time. We performed a prospective, 30 month longitudinal, observational multi-center study of adults initiating nusinersen with SMA types II/III to examine its safety, tolerability, and effectiveness. 43 participants (20 female; 14 ambulatory; 3, 17, and 23 with 2, 3, and ≥4 SMN2 copies, respectively), mean (SD) age …

From Low Field To High Value: Robust Cortical Mapping From Low-Field Mri, Karthik Gopinath, Timothy Coalson, Matthew F Glasser, David Van Essen, Et Al.

2020-Current year OA Pubs

Three-dimensional reconstruction of cortical surfaces from MRI for subsequent morphometric analysis is fundamental for understanding brain structure. While high-field Magnetic Resonance Imaging (HF-MRI) is the standard in research and clinical settings, its relatively limited availability hinders widespread use. Low-field MRI (LF-MRI), particularly portable systems, offers a cost-effective and accessible alternative. However, existing cortical surface analysis tools, such as FreeSurfer, are optimized for high-resolution HF-MRI and struggle with the lower signal-to-noise ratio (SNR) and resolution of LF-MRI. In this work, we present a machine learning method for 3D reconstruction and analysis of portable LF-MRI scans over a range of contrasts and …

BACKGROUND: The phrase "getting it" is frequently used in surgical trainee assessment, yet its meaning remains undefined. This study explores how residents and faculty define the concept and whether perceptions align.

METHODS: Semi-structured interviews were conducted with 11 residents and 13 faculty at a single institution and analyzed using reflexive thematic analysis.

RESULTS: Residents described "getting it" as clinical competence, social awareness, feedback responsiveness, and team integration, while noting challenges with interpreting implicit expectations and the influence of faculty bias. Faculty described "getting it" as a gestalt recognition of initiative, insight, and sound clinical judgment. Both agreed that the concept …

Hematopoietic Cell Transplant Access And Patient Diversity, Rachel Cusatis, Ramzi Abboud, Et Al.

2020-Current year OA Pubs

IMPORTANCE: Allogeneic hematopoietic cell transplant (HCT) is curative for hematologic cancers, yet access remains inequitable for racially and ethnically underrepresented and socioeconomically disadvantaged populations, making the goal of having a suitable donor for every patient who needs a transplant challenging. The ACCESS trial broadened access by enrolling patients without matched donors, who instead received an HCT from a mismatched unrelated donor.

OBJECTIVE: To compare baseline characteristics of ACCESS trial participants with participants enrolled in a similar clinical trial and a patient-reported outcome (PRO) protocol cohort.

DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study included adult participants (aged ≥18 years) from 3 …
