What Is Screen Apnea And How Does It Affect You?, Kristi M. Soileau May 2026

What Is Screen Apnea And How Does It Affect You?, Kristi M. Soileau

New Orleans Dental Association News

Screen apnea is a modern epidemic of significant proportions. Research suggests that nearly 80% of people unconsciously alter their breathing, often holding their breath or breathing shallowly, while working on digital devices. This subtle shift in respiration, sometimes called “email apnea,” can place the body into a low-grade stress response without being noticed by the individual at the screen. When breathing becomes restricted from poor posting or content anxiety, the nervous system enters into a sympathetic response, much as it interprets signs of threats to that person. The resultant physiological response may be exhibited by muscle tension, mental fog, increased …

Wills Eye Hospital Papers

OBJECTIVE: Systemic antihypertensive medications may influence glaucoma-related outcomes through intraocular pressure-dependent and vascular mechanisms. While topical α₂-agonists are established glaucoma therapies, the association between systemic α₂-agonists and glaucoma hazard remains unexamined; we compared their hazard with systemic β-blockers in adults with hypertension.

METHODS AND ANALYSIS: We conducted a multicentre retrospective cohort study using deidentified electronic health records. Adults aged ≥40 years with hypertension and chronic exposure to systemic α₂-agonists or β-blockers were included. Patients with pre-existing ocular hypertension (OHT), primary open-angle glaucoma (POAG), concomitant comparator use, or inadequate ophthalmic follow-up were excluded. We balanced cohorts using propensity score matching (PSM) …

Multi-Site Dms Probing Reveals Higher-Order Structure Of Rna-Protein Complexes In Living Cells, Anthony Hoang, Joshua Meehan, Ritwika Bose, David Mitchell, David H Price, Calla M Olson, Chase A Weidmann, Anthony M Mustoe

Faculty, Staff and Students Publications

Identifying tertiary structures and protein binding sites in RNA molecules remains a key challenge in RNA biology. We describe multi-site dimethyl sulfate (DMS)-mutational profiling (MaP) (msDMS-MaP), a strategy that enables simultaneous measurement of RNA secondary, tertiary, and quaternary structures via a single DMS chemical probing experiment. Optimized reverse transcription decodes typically invisible DMS N7-methylguanine (N7-G) modifications via a tautomer-induced mutational signature concurrent with N1 and N3 modifications. We show that N7-G reactivity reports on higher-order RNA structures, revealing key functional motifs such as pseudoknots and protein binding sites. Using msDMS-MaP, we find that E. coli ribosomal RNAs encode numerous independently …

Ultra-Rare Functional Variants Reveal Early-Onset Breast Cancer Risk Genes And Pathways In The Uk Biobank And All Of Us Research Program, Chen Wang, Panagiotis Katsonis, Yi Li, Lawrence A Donehower, Olivier Lichtarge

Faculty, Staff and Students Publications

Breast cancer (BRCA) affects one in eight women, and while past studies have identified susceptibility genes and variants, those driving early-onset disease remain opaque. We introduce EA-Pathways, a control-free association method that aggregates ultra-rare germline coding variants weighted by Evolutionary Action to detect functional impact distribution biases in genes and pathways. In UK Biobank women with BRCA, EA-Pathways prioritized candidate risk genes across pathways enriched in known familial genes. Ultra-rare, high-impact variants in these genes were BRCA specific, and variants from eight pathways were associated with 2-year-earlier disease, including homology-directed DNA repair, TP53, and pexophagy pathways. The early-onset effect replicated …

Short-Term Bayesian Influenza Forecasting In A Hospital Environment Using A Linear Kalman Filter., Shankar Kaleeswaran Mani, Grzegorz A Rempala, Eben Kenah, Fernanda L Schumacher

Ambulatory and Primary Care Articles

Accurately forecasting the weekly number of influenza (flu) lab tests and positive cases is important for hospitals as they work to plan staffing, manage supplies, and provide timely patient care. In this paper, we describe a practical use of a Bayesian Kalman filter to forecast weekly flu tests and positives in a hospital setting. Using data from a large hospital system in Ohio, we show that this approach, which blends real-time hospital information with historical patterns, offers a dependable way to anticipate flu-related patient volume as far as four weeks ahead.


A Case Of Successful Survival In A High-Risk Elderly Patient With Copd After Endotracheal Intubation, Julia Cueto Oms-Ii May 2026

A Case Of Successful Survival In A High-Risk Elderly Patient With Copd After Endotracheal Intubation, Julia Cueto Oms-Ii

Rowan-Virtua Research Day

Exacerbations of chronic obstructive pulmonary disease (COPD) leading to acute respiratory failure (ARF) is one of the major causes of mortality worldwide, thus typically having poor outcomes. Risk factors such as the need for invasive mechanical ventilation (IMV), severity of disease, comorbidities, and increased age are predictors of increased mortality rates in COPD patients. Noninvasive ventilation (NIV), like bilevel positive airway pressure (BiPAP) or high flow nasal cannula (HFNC), is the initial standard of care for acute exacerbations of COPD. However, longer periods of NIV and failure of NIV therapy can lead to delayed endotracheal intubation and higher mortality rates. …

A Neck Too Tight: Emergent Cricothyrotomy For Airway Collapse From Expanding Post Anterior Cervical Discectomy And Fusion (Acdf) Hematoma, Nicole R. Eregha, Kishan Patel, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Anterior cervical discectomy and fusion (ACDF) is a commonly performed surgical procedure used to treat cervical spine pathology including radiculopathy and spinal cord compression. Although generally safe, postoperative complications can occur. One of the most feared complications is expanding neck hematoma, which may lead to rapid airway obstruction due to tracheal compression and soft tissue swelling. The reported incidence of postoperative hematoma after ACDF ranges from 0.2–1.9%, with a subset of patients requiring emergent airway intervention or surgical evacuation [1]. Patients with postoperative hematoma typically present with neck swelling, dysphagia, hoarseness, dyspnea, and inability to tolerate secretions, symptoms that may …


Learning From Our Dental Colleagues: A Brief Review Of Counter-Stimulation To Reduce Procedural Pain In Emergency Medicine Mechanisms, Existing Evidence, And A Pragmatic Research Agenda, James Espinosa, Neal Appelstein, Alan Lucerna May 2026

Learning From Our Dental Colleagues: A Brief Review Of Counter-Stimulation To Reduce Procedural Pain In Emergency Medicine Mechanisms, Existing Evidence, And A Pragmatic Research Agenda, James Espinosa, Neal Appelstein, Alan Lucerna

Rowan-Virtua Research Day

Counter-stimulation techniques such as tapping, pressure, vibration, and tissue shaking are commonly observed in dental practice during administration of local anesthetic nerve blocks. Although not systematically described in the Emergency Medicine literature, individual clinicians may employ tactile counter-stimulation techniques during needle-based procedures. The practice remains under-theorized and under-studied within the Emergency Medicine literature. This brief review synthesizes mechanistic neurobiology—including segmental gate control theory (Melzack & Wall, 1965), descending inhibitory modulation, and attentional salience models—with evidence from dental and needle-procedure research. We propose a practical taxonomy of counter-stimulation techniques applicable to Emergency Medicine and identify gaps in the current literature. Finally, …


From Confirmation To Guidance: Making The Case For Intraprocedural Pocus As The Next Developmental Step In Ultrasound-Supported Shoulder Reduction A Conceptual Practice Proposal And Research Agenda, James Espinosa May 2026

From Confirmation To Guidance: Making The Case For Intraprocedural Pocus As The Next Developmental Step In Ultrasound-Supported Shoulder Reduction A Conceptual Practice Proposal And Research Agenda, James Espinosa

Rowan-Virtua Research Day

Point-of-care ultrasound (POCUS) is well established for the diagnosis of shoulder dislocation and for the confirmation of successful reduction. However, its role during the reduction maneuver itself remains under-described. This conceptual practice proposal argues that intraprocedural POCUS represents the logical next developmental step in ultrasound-supported shoulder reduction. By introducing real-time visualization of humeral head translation during reduction attempts, clinicians may identify ineffective vectors earlier, adjust technique midstream, and potentially reduce repeated attempts or escalation of procedural sedation. This work does not present outcome data but instead proposes a practical framework, workflow model, and research agenda for intraprocedural implementation. Future study …


Improving Emergency Department Throughput: Implementation Of A Nurse-Driven Protocol In Pediatric Fast-Track Patients Presenting With Fever, Kerrigan A. Teeple May 2026

Improving Emergency Department Throughput: Implementation Of A Nurse-Driven Protocol In Pediatric Fast-Track Patients Presenting With Fever, Kerrigan A. Teeple

Evidence-Based Practice Project Reports

Overcrowding in the emergency department presents significant operational challenges and is associated with adverse patient outcomes (Gottlieb et al., 2020). Despite throughput initiatives, increasing patient acuity and rising census levels continue to strain emergency department efficiency. This quality improvement project evaluated whether implementing a fever-reduction standing order protocol could reduce door-to-provider and door-to-disposition times for pediatric fast-track patients presenting to the emergency department. A review of evidence across 6 databases identified nurse-initiated standing orders as a best-practice strategy to expedite care, improve throughput, and reduce delays in disposition. Guided by this evidence, a standing order protocol for acetaminophen administration was …

Barriers To Palliative Care Access In Rural South Dakota: A Policy And System-Level Analysis, Harshavardhan Kadarkaraisamy

Honors Thesis

Palliative care improves the quality of life for people living with serious illness. It helps by addressing symptoms, improving communication, and providing mental, physical, and spiritual support. However, in South Dakota access to palliative care is limited in rural areas. These challenges include geographic isolation, workforce shortages, healthcare infrastructure, reimbursement, and misunderstandings about palliative care. This thesis examines the key policy barriers that limit access to palliative care in rural South Dakota. This work involves engaging with South Dakota-specific literature, rural health research, policy sources, community education, telehealth expansion, and policy reform. By focusing on the rural context of South …

Genecov, Christopher F. Drescher, Heather Bruschwein, Chelsi N. Nurse, Katherine Lawliss, Darcy C. Esiason, Gunnar H. Esiason

Department of Psychiatry and Human Behavior Faculty Papers

BACKGROUND: Existing mental health self-report measures have been criticized for over-simplification, lack of CF-specific focus, susceptibility to measurement reactivity bias, and conflation of symptoms of anxiety and/or depression with CF-related symptoms and/or treatment side effects. The CF Mental Health and Wellness Questionnaire (CFMHWQ) is a 25-item measure assessing CF-specific mental health burden symptoms.

METHODS: To examine common underlying factors contributing to scores on the CFMHWQ, principal component analysis (PCA) was conducted of all 25 items. We conducted cross-validation of CFMHWQ principal components, examining unadjusted correlations between each principal component, demographic characteristics (age and biological sex), negative affect (mean rank global …


The Meaning Of Physical Activity In The Context Of Health Sciences: A Concept Analysis, Martín G. Farinola May 2026

The Meaning Of Physical Activity In The Context Of Health Sciences: A Concept Analysis, Martín G. Farinola

International Journal of Physical Activity and Health

Physical activity has been defined in numerous ways. Thus, this study aimed to conduct a concept analysis of the existing physical activity definitions in the health sciences literature to evaluate its conceptual precision and assess the need for a revised or novel concept better suited for this domain. The concept analysis was accomplished using tools derived from philosophical semantics. The analysis identified six definitions that explicitly state what physical activity is with sufficient clarity to allow for conceptual examination. The findings indicated that these definitions frequently merge the concept of physical activity with its contextual attributes. To address these semantic …

Diabetic Nephropathy Masquerading As Systemic Disease: The Critical Role Of Renal Biopsy In A Young Uninsured Woman With Nephrotic Syndrome, Yolanda V. Gutierrez, Alexis Vargas Del Toro, Cristina Kochi Yamamoto, Jose Loayza Pintado, Andres Suarez-Parraga

School of Medicine Publications

Nephrotic syndrome can have overlapping features across multiple diseases, making diagnosis difficult without tissue confirmation. We describe a 30-year-old uninsured Hispanic woman with type 1 diabetes, hypertension, and CKD3B who presented with nephrotic syndrome, sepsis, and progressive muscle weakness. Her pleural effusions, periorbital changes, elevated free light chains, and dysphagia raised concern for systemic conditions such as amyloidosis or polymyositis, especially given inconsistent outpatient follow-up. Because her management would differ significantly depending on the underlying cause and due to the high risk of loss to follow-up, a renal biopsy was pursued. Serologic studies were unremarkable, and biopsy ultimately confirmed diabetic …
