Myocardin Effector Proteins Affect Tgf-Beta-Induced Myofibroblast Differentiation In Ipf Cells, Allison Gonzalez

Biotechnology Theses

Idiopathic pulmonary fibrosis (IPF) is an incurable interstitial lung disease defined by the progressive, irreversible scarring of the tissues between the lung’s alveoli. To date, only two drugs have received approval for treatment. However, these medications are not considered cures since they do not stop the progression of the disease. A deeper understanding of the mechanisms underlying IPF could aid in discovering a cure. We recently found that myocardin (MyoCD) regulates SMAD2/3 transcription factors in the TGF-β signaling pathway and governs the genes involved in pleural fibrosis. However, it is unclear whether MyoCD plays a critical role in IPF by …

The University of Louisville Journal of Respiratory Infections

Introduction: Bronchiectasis, currently being recognized worldwide, is an abnormal dilatation of the bronchi and bronchioles brought on by recurrent cycles of inflammation and airway infection. Impaired pulmonary function has a predictive significance in bronchiectasis. When treating patients with suspected or confirmed respiratory diseases, pulmonary function tests (PFT) are useful examinations. Very few studies have been done on PFTs in bronchiectasis. The main aim of this study is to study PFTs in bronchiectasis.

Method: This is a retrospective observational study done on 50 patients over two years at the tertiary care center. The previous records of patients were collected from the …

Teaming Up For Better Health: An Interprofessional Collaborative Approach To Older Adult Oral Care, Deborah Dowd, Jodie Lopez, Jennifer Goodman

Utah Conference on Community Engagement

Oral health is a critical component of overall health, significantly influencing systemic diseases and the quality of life in older adults. Conditions such as xerostomia, swallowing difficulties, and poor oral self-care are associated with aspiration pneumonia. Integrating oral health into healthcare in long-term care facilities (LTCFs) is essential for preventing various conditions and improving quality of life. Effective oral hygiene is crucial in avoiding non-ventilator hospital-associated pneumonia by reducing oral biofilm and lowering the risk of pneumonia. Nurses' knowledge and care in oral health across healthcare settings are vital for positive health outcomes. Revising nursing curricula to incorporate oral health …

Identification And Preclinical Assessment Of Novel Therapeutic Modalities In Environmental Exposure-Induced Lung Disease, Aaron D. Schwab

Theses & Dissertations

Environmental lung diseases are preventable respiratory conditions either caused or made worse by inhaled environmental exposures. Contemporarily, environmental lung diseases are most associated with workplace exposures given specific occupational processes aerosolize inflammatory agents that can be inhaled at high concentrations. Although a considerable amount is known regarding immunoglobulin (Ig)E-mediated responses to environmental exposures, little is known about non-IgE mediated respiratory conditions resulting from lipopolysaccharide (LPS)-enriched organic dust exposure(s). Chronic respiratory diseases such as asthma, hypersensitivity pneumonitis, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis have all been identified as environmental lung diseases caused or exacerbated by such environmental dusts. Therapeutic …

Pseudomonas Aeruginosa Exoy Enzymatic Activity Inhibits Exos-Induced Caspase-3/7 Activation But Not Cytotoxicity In Pmvecs, Connor Holm

Poster Presentations

Pseudomonas aeruginosa (P. aer.) is the most common cause of ventilator associated pneumonia (VAP) in ICU patients. Different combinations of exoenzymes (S, T, Y, and U) are found in P. aer. strains. ExoY is most often associated with VAP in ICU patients. ExoY infection of pulmonary microvascular endothelial cells (PMVECs) induces cell rounding but does not activate intracellular caspase-3/7 or cause cell death. ExoS and ExoT infection of epithelial cells leads to caspase-3/7 dependent cell death. Previous studies using epithelial cells show that ExoY alleviates the cytotoxic effects of ExoS and ExoT. Here, we sought to determine whether ExoY inhibits …

Case Report: Hyperkalemia Secondary To Acute Respiratory Acidosis, Chetna Thawani

Rowan-Virtua Research Day

Hyperkalemia is a potentially life-threatening electrolyte disturbance, commonly associated with renal dysfunction, medication effects, and acid-base imbalances. While metabolic acidosis is a well-known cause of transcellular potassium shifts, respiratory acidosis is a less recognized but significant contributor. This case report presents a 74-year-old female with hyperkalemia in the setting of acute respiratory acidosis secondary to impaired ventilation from rib fractures. This case highlights the importance of recognizing respiratory acidosis as a potential cause of hyperkalemia and tailoring management to address the underlying issue

Cannabinoid Hyperemesis Syndrome Induced Pneumomediastinum In An Adolescent, Julian Coz, Christopher Schwartz, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Cannabinoid hyperemesis syndrome (CHS) is a condition characterized by cyclic episodes of severe nausea, vomiting, and abdominal pain in individuals with chronic cannabis use. Despite its increasing recognition, CHS remains underdiagnosed, particularly in adolescents, and can be associated with a range of complications, some of which are potentially life-threatening. One such complication is spontaneous pneumomediastinum (SPM), a rare but serious condition where air accumulates in the mediastinum without any clear traumatic cause. Although SPM is typically benign, it can present with significant respiratory distress and requires prompt identification and management. Here we present the case of an 18-year-old patient with …

This case report details a 65-year-old female who experienced a suspected TCA overdose as a suicide attempt. She had a history of depression and a previous suicide attempt. The patient was unresponsive with declining oxygen saturation, necessitating emergent intubation. Important lab findings included a decreased partial pressure of oxygen to fraction of inspired oxygen ratio (P/F ratio) and prolonged QRS …

Expanding Inducible Epithelial Resistance Against Pneumonia: Novel Virus, Novel Receptor, Michael Longmire

Dissertations and Theses (Open Access)

Pneumonia is the leading infectious cause of death worldwide and presents a continuing risk among immunocompromised patients. Our work has been focused for many years on the phenomenon of inducible epithelial resistance, where activation of the innate immune response in the airway epithelium is necessary and sufficient to produce a pathogen-killing but self-protective environment to prevent severe disease. Inducible resistance is pathogen-agnostic and has been demonstrated against an array of respiratory infections. We achieve this using a combination of pattern recognition receptor agonists – Pam2CSK4 and ODN M362 being the current formulation – which produce synergistic levels of pathogen reduction …

Examining The Role Of Corticosteroids In The Management Of Acute Interstitial Pneumonia: A Systematic Review., Carlos Valladares, Aalia Narvel, Bianna Koutsenko, Alexa Simonetti, Fatima Mossolem, Alexis Chow, Samrat Gollapudi, Usmaan Al-Shehab, Nicholas Averell, Katherine Chiapaikeo-Poco, Adam Kaplan

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Acute interstitial pneumonia (AIP), also known as Hamman-Rich syndrome, is a rapidly progressive interstitial lung disease. In addition to being challenging to diagnose, AIP is also difficult to treat. The mortality rate of AIP is greater than 70% due to the disease's rapid progression. Furthermore, survivors are likely to develop chronic interstitial lung disease as a sequela. Treatment primarily focuses on supportive care, which consists of oxygenation through mechanical ventilation, administration of broad-spectrum antibiotics, and the use of corticosteroids. Although the use of steroids as empiric treatment is controversial and results on its mortality benefit are variable, some studies …

Integrated Health Sciences Faculty Research

The long non-coding RNA EP300-AS1 (lncRNA EP300-AS1), identified as a potential regulatory factor in various cancers, remains underexplored in nasopharyngeal carcinoma (NPC). This study investigated EP300-AS1’s regulatory mechanisms in NPC, particularly its interaction with transcription factor AP-2 Gamma (TFAP2C) and its effect on cystatin E/M (CST6) expression. Employing clinical samples and NPC cell lines, we conducted in vitro and in vivo xenograft experiments to assess the impacts of modulating EP300-AS1 expression. Techniques such as CCK8, migration, scratch, apoptosis assays, cell cycle analysis, immunoblotting, and fluorescence experiments elucidated EP300-AS1’s role in NPC. The interaction between EP300-AS1 and TFAP2C in regulating CST6 …

Markers Of Growth And Nutrition In Children With Acquired Chylothorax Post Chd Surgery, Kevin N. Marzotto, Karin R. Videlefsky, Meghan P. Howell, Thomas R. Kimball, Frank A. Pigula, Kurt D. Piggott

School of Medicine Faculty Publications

Background: Acquired chylothorax is an established complication of CHD surgery, affecting 2-9% of patients. CHD places a child at risk for failure to thrive, with subsequent chylothorax imposing additional risk. Objective: We conducted a retrospective chart review to ascertain quantitative markers of nutrition and growth in children affected by chylothorax following CHD surgery between 2018 and 2022 compared to controls. Methods: We utilised electronic medical record system, EPIC, at Children's Hospital, New Orleans, targeting subjects < 18 years old who underwent CHD surgery between 2018 and 2022 and developed a subsequent chylothorax. Study subjects were identified using the 10th revision of the International Classification of Diseases codes (ICD-10 codes: J94.0, I89.8, and J90.0). Each chylothorax case (n = 20) was matched by procedure type and age to a control with no chylothorax (n = 20). Data were recorded in REDCap and analysed using SPSS. Results: After removal of outliers, we analysed 19 total matched pairs. There was no statistical difference in growth velocity (p = 0.12), weight change (operation to discharge) (p = 0.95), weight change (admission to discharge) (p = 0.35), Z-score change (operation to discharge) (p = 0.90), Z-score change (admission to discharge) (p = 0.21), serum protein (p = 0.88), or serum albumin (p = 0.82). Among cases, linear regression demonstrated no significant association between maximum chylous output and growth velocity (p = 0.91), weight change (operation to discharge) (p = 0.15), or weight change (admission to discharge) (p = 0.98). Conclusions: We did not observe statistically significant markers of growth or nutrition in children with chylothorax post-CHD surgery compared to those without chylothorax. Multisite data collection and analysis is required to better ascertain clinical impact and guide clinical practice.
