Quantifying Black Carbon Concentrations in Georgia and Analyzing Associated Public Health Risks

One of the most daunting challenges of the industrial world is air pollution. Within this broad spectrum, there is an inhalable particle group named PM2.5, which contains black carbon. Black carbon has evidence that supports the generation and worsening of adverse health impacts, which may include birth complications, cognitive deficits in children, pulmonary aggravation, asthma, cardiovascular issues, neurological degenerative patterns, and cancer risk. This is especially seen in vulnerable populations, like children, elderly, and those who already suffer from weakened health, many of which reside in the southern …


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 …

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 …

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 …

Predicting Narcissism Through Social Media, Cameryn Freglette, Melanie Palomares

Caravel Undergraduate Research Journal

The objective of this study was to assess if narcissism can be predicted through social media behaviors such as frequency of posts, posting selfies, and social media presence on a variety of platforms. This study was conducted through a questionnaire related to social media use and a brief assessment from the Narcissistic Personality Inventory (NPI- 16). Results indicated that social media use per day was significantly different between people who post selfies and those who do not. Participants that scored higher for narcissism used social media less but posted significantly more selfies. Results were not significant in predicting narcissism through …


Dexmedetomidine And The Prevention Of Emergence Agitation In Military Veterans With Post-Traumatic Stress Disorder, Taylor P. Ranegar May 2026

Dexmedetomidine And The Prevention Of Emergence Agitation In Military Veterans With Post-Traumatic Stress Disorder, Taylor P. Ranegar

Doctor of Nursing Practice Scholarly Projects

Emergence agitation (EA) is a post-anesthetic complication that occurs when the patient is in a self-limited, nonfluctuating state of excitement while transitioning into a state of consciousness. EA can lead to negative adverse outcomes including, accidental invasive line removal, bleeding, respiratory depression, unintentional extubation, and injury to the staff and the patient. EA is often observed in military veterans who have a medical history of post-traumatic stress disorder (PTSD). For patients with a history of military exposure undergoing elective general anesthesia who also have PTSD, anxiety, and or depression, the incidence of EA was estimated to be around 27%. The …

Introduction: Early open fracture management aims to minimise the risk of complications. For the most severe open fracture wounds, multiple irrigation and debridement surgeries are required to overcome severe wound contamination, to reassess the evolving tissue injury or to temporise and plan further surgery. When multiple irrigation and debridement surgeries are needed, uncertainty remains about how the open fracture wound should be managed to best minimise complications. The primary aim of this trial is to compare the antibiotic cement bead pouch vs negative pressure wound therapy in the management of patients with severe open tibia fracture wounds.

Methods and analysis: …


Heads Up! Designing A Nursing Assessment Tool For Early Recognition Of Intracranial Hypertension Post Head Injury, Sergio A. Dondiego May 2026

Heads Up! Designing A Nursing Assessment Tool For Early Recognition Of Intracranial Hypertension Post Head Injury, Sergio A. Dondiego

Honors Capstones

This meta-analysis identifies noninvasive clinical predictors of intracranial hypertension (IH) post head trauma to develop a multi-criteria IH screening tool designed for nurses to wear on their badge reels. High-sensitivity predictors were prioritized to assist in early IH suspicion. Findings suggest that radiographic-measured abnormalities including an optic nerve sheath diameter (ONSD) 5.6 mm and signs of significant head trauma via computed tomography (CT) were highly effective for predicting IH and were therefore defined as major criteria for the assessment tool. Other significant examination findings include a Glasgow Coma Scale (GCS) score 8 and atypical pupillary reactivity. While age showed conflicting …

Experiences Of Discrimination, Paternal Support, And Hypertensive Disorders Of Pregnancy (Hdp) In The Miehr Study, Houston, Texas, Tahereh Alinia, Elaine Symanski, Juan Manuel Alvarez, Kristina Walker Whitworth

Faculty, Staff and Students Publications

Background: Discrimination is a psychosocial stressor that, through activation of stress-response pathways, may influence risk of adverse perinatal health outcomes. However, few studies have evaluated the association between discrimination and hypertensive disorders of pregnancy (HDP), and none have explored effect modification by race or paternal support, which may buffer the adverse effects of discrimination.

Methods: We included 1,847 non-Hispanic Black and White participants from the Maternal and Infant Environmental Health Riskscape (MIEHR) study. Krieger's validated Experiences of Discrimination (EOD) scale was used to assess occurrence (yes/no) and frequency (once, 2-3, ≥ 4 times) of discrimination in nine situations. We created …

The Power Of Belief: Investigating The Intersection Of Religious Observance, Social Support, And Psychological Distress, Victoria R. Atwater

Undergraduate Honors Thesis Collection

Religion can act as a protective factor against stress and depression (Koenig et al., 2009; Krok, 2008) and can be examined through an individual’s relationship with religion or the efficacy of religious practices on mental health. In this study, 206 participants completed an online questionnaire that measured stress, depression, religious coping, religiosity (intrinsic religiosity, organized religious activities and non-organized religious activities), and social support using validated scales. The results indicate a positive correlation between stress, depression, and negative religious coping as predicted. While intrinsic religiosity and positive religious coping did not significantly influence stress or depression, organized religious activities were …


Evaluating Spect Neuroimaging In Psychiatric Diagnosis: A Critical Review And Proposed Randomized Controlled Study, Kiley Carter May 2026

Evaluating Spect Neuroimaging In Psychiatric Diagnosis: A Critical Review And Proposed Randomized Controlled Study, Kiley Carter

Senior Honors Theses

Mental illness affects a substantial proportion of adults in the United States, yet psychiatric diagnosis remains subject to diagnostic variability. Single-photon emission computed tomography (SPECT) is a neuroimaging technique that measures cerebral blood flow and has been proposed as an adjunctive tool for psychiatric evaluation. Existing literature reports group-level perfusion patterns associated with certain psychiatric conditions, suggesting potential utility in diagnosing complex or treatment-resistant cases. However, critics of SPECT emphasize the absence of randomized controlled data demonstrating improved patient outcomes. To address this gap, a prospective randomized controlled trial comparing standard psychiatric care with SPECT-guided evaluation is proposed. The proposed …

Faculty, Staff and Student Publications

Background: Hemorrhagic shock (HS) following traumatic injury is hallmarked by innate immune activation, hypercoagulability, and thromboinflammatory complications. To date, the direct link between HS, injury severity, and endothelial cell (EC) contributions to thromboinflammation remains poorly understood. The goals of this study were to determine the impact of injury severity and HS on endothelial-mediated thromboinflammation and examine whether these changes increase the propensity for thrombosis.

Methods: Plasma from 89 male trauma patients, stratified by HS and injury severity, and 10 healthy subjects were assessed for inflammatory mediators by BioPlex. Human lung microvascular endothelial cells were exposed to patient plasma for 4 …


Novel Biomarker Discovery In Multiple Sclerosis, Manisha Gangasani May 2026

Novel Biomarker Discovery In Multiple Sclerosis, Manisha Gangasani

Honors Theses

Multiple Sclerosis (MS) is a chronic neuroinflammatory disorder affecting the brain, spinal cord, and optic nerve. Patients experience cognitive, motor, autonomic, and emotional symptoms that often overlap with other neurological conditions, making early diagnosis challenging. Current diagnostic criteria require evidence of lesions with dissemination in time and space. Racial disparities in MS outcomes are well documented, with Black individuals often exhibiting greater disease severity, higher relapse rates, and increased disability compared to White individuals. These differences likely reflect a combination of genetic, biological, environmental, and healthcare access factors, underscoring the need to improve early diagnosis and reduce inequities in care. …


An Investigation Of The Roles Aging, Gender And Age-Related Hearing Loss Play In Emotional Prosody Recognition, Giavanna Yowell May 2026

An Investigation Of The Roles Aging, Gender And Age-Related Hearing Loss Play In Emotional Prosody Recognition, Giavanna Yowell

Undergraduate Honors Thesis Collection

Emotional prosody recognition is crucial for social interactions but is influenced by aging, gender, and age-related hearing loss (Lambrecht et al., 2012; Oerlemans et al., 2014; Palermo et al., 2013). No past studies have looked at all of these factors collectively. To address this shortcoming, the current study explored the relationships between aging, hearing loss and gender differences in emotional prosody recognition. The ability to recognize emotions through facial expressions was also included as a comparative measure. One hundred fifteen individuals (42 men and 73 women), ages 50 and older (M = 60.39, SD = 8.12), completed a hearing handicap …

Department of Pediatrics Faculty Papers

Pentobarbital is a barbiturate with sedative and anticonvulsant properties, occasionally used in pediatric patients for preoperative sedation, deep sedation during mechanical ventilation, and seizure control. Despite its long-standing clinical use, age-appropriate dosing remains challenging due to variability across studies and limited pediatric pharmacokinetic (PK) data. This study (NCT01431326) aimed to characterize the population pharmacokinetics of pentobarbital in pediatric patients (birth to 21 years) and evaluate dosing strategies using model-based simulations. A two-compartment population PK model, allometrically scaled to total body weight, adequately described pentobarbital plasma concentrations, with no additional covariates identified as significant. Simulations were conducted across four age groups: …


Prefrontal Engagement In Cognitive Flexibility Across Paradigms, Katarina Kalajzic May 2026

Prefrontal Engagement In Cognitive Flexibility Across Paradigms, Katarina Kalajzic

Honors Scholar Theses

Cognitive flexibility is an executive function that involves dynamically adapting behavior in the face of changing environmental circumstances to achieve a particular goal. Disrupted in numerous psychiatric disorders such as Alzheimer’s disease, schizophrenia, OCD, and depression, the neural correlates of cognitive flexibility are not well understood. However, the prefrontal cortex (PFC) is strongly implicated in executive function and attentional control processes. Thus, we sought to examine the neural circuitry involved in distinct cognitive flexibility tasks – the attentional set-shifting task and the probabilistic 2-armed bandit task. Through optogenetic suppression, we targeted pyramidal neurons of the rodent medial prefrontal cortex, an …


Validation Of A Real-Time Pcr Laboratory Developed Test For The Detection Of Pneumocystis Jirovecii In Bronchoalveolar Lavage Samples, Caitlyn Moon May 2026

Validation Of A Real-Time Pcr Laboratory Developed Test For The Detection Of Pneumocystis Jirovecii In Bronchoalveolar Lavage Samples, Caitlyn Moon

Honors Scholar Theses

Pneumocystis jirovecii is an opportunistic, host-obligate fungal pathogen responsible for causing P. jirovecii pneumonia (PJP) in humans. PJP is treated with trimethoprim-sulfamethoxazole (TMP-SMX), a strong broad-spectrum antibiotic that carries risk of renal and hepatotoxicity. Therefore, rapid diagnosis or exclusion of PJP is crucial to ensure PJP-positive patients receive effective treatment and PJP-negative patients avoid unnecessary antibiotics. Unlike most microorganisms, P. jirovecii cannot be cultured, presenting complications for the typical methods of diagnosing fungal pathogens. Historically, the gold standard for diagnosis was direct microscopic examination with stains such as methenamine silver and calcofluor white, but this diagnostic technique requires highly skilled …


The Development Of A Crispr-Based Calibrated Functional Assay For Classifying Pathogenicity Of Msh2 And Msh6 Variants In Lynch Syndrome, Olivia N. Amodeo May 2026

The Development Of A Crispr-Based Calibrated Functional Assay For Classifying Pathogenicity Of Msh2 And Msh6 Variants In Lynch Syndrome, Olivia N. Amodeo

Honors Scholar Theses

Lynch syndrome is a hereditary disease caused by the inheritance of a mismatch repair gene variant. Individuals with this condition are predisposed to cancer development, most commonly colorectal cancer. Current guidelines for variant classification are based on numerous evidence categories, including functional evidence. However, many novel clinical variants are not well characterized, and evidence is difficult to obtain if functional assays are not calibrated.

To address this, our lab created a calibrated functional assay that calculates an odds of pathogenicity score for MSH2 and MSH6 gene variants that can be used as evidence for classifying variants of uncertain significance. This …
