Bubble continuous positive airway pressure (bCPAP) is a minimally invasive respiratory support for neonates experiencing respiratory distress syndrome (RDS). It exerts continuous, oscillatory air pressure to encourage lung function and development. Neonates’ movement may cause disconnections at the nasal interface. These disconnections are characterized by the cessation of bubbling at the bCPAP respiratory circuit output and frequently go unnoticed until hypoxia develops. Common Neonatal Intensive Care Unit (NICU) bCPAP systems lack a built-in alarm or accessory device to monitor for disconnections. As a result, nursing personnel must exercise extreme caution utilizing current bCPAP procedure. If a neonate is disconnected, it …

From Molars To Bronchus; The Tale Of An Aspirated Dental Instrument, Yisroel Grabie, Sudeep Acharya, Fasih Sami Siddiqui, Gabriel A. Chavez Reyna, Michel Chalhoub

HCA Healthcare Journal of Medicine

Background

Aspiration of dental instruments is a rare event that carries potentially serious complications when it occurs, especially in older patients, where protective reflexes are diminished. Clinical management may be difficult because of the risk of granulation tissue and different retrieval strategies according to the object’s characteristics. In this report, we describe the case of an 84-year-old man who aspirated a dental bur during a routine dental procedure, necessitating immediate intervention. Timely and precise management was essential to avert severe complications.

Case Presentation

During a routine dental procedure, an 84-year-old man aspirated a bud-shaped cross-cut carbide dental bur. Despite initial …

The Effectiveness Of The Gnana Laryngeal Mask Airway Ii (Gla-Ii) With Novel Suction Tubing In Gastrointestinal (Gi) Cases, Shahab Ahmadzadeh, Landyn D. Johnson, William T. Barham, James Ilochi, Matthew Fredericks, Giustino Varrassi, Sahar Shekoohi, Alan D. Kaye

School of Medicine Faculty Publications

INTRODUCTION: The Gnana laryngeal mask airway II (GLA-II) is a supraglottic airway device similar to the classic laryngeal mask airway, except it has an additional suction port. This suction port allows for the removal of secretions and saliva. A previous version of the Gnana laryngeal airway 4 was made of silicone, while this newer version is made of polyvinyl chloride (PVC), which is more affordable. This study aimed to demonstrate the effectiveness and tolerability of this PVC-designed GLA-II and evaluate its ability to suction secretions. METHODS: The prospective cohort study included 100 gastrointestinal (GI) cases to determine the effectiveness and …

Hsp70 Is A Critical Regulator Of Hsp90 Inhibitor's Effectiveness In Preventing Hcl-Induced Chronic Lung Injury And Pulmonary Fibrosis, Ruben M. L. Colunga Biancatelli, Pavel A. Solopov, Tierney Day, Betsy Gregory, Michael Osei-Nkansah, Christiana Dimitropoulou, John D. Catravas

Exposure to hydrochloric acid (HCl) can provoke acute and chronic lung injury. Because of its extensive production for industrial use, frequent accidental exposures occur, making HCl one of the top five chemicals causing inhalation injuries. There are no Food and Drug Administration (FDA)-approved treatments for HCl exposure. Heat shock protein 90 (HSP90) inhibitors modulate transforming growth factor-β (TGF-β) signaling and the development of chemical-induced pulmonary fibrosis. However, little is known on the role of Heat Shock Protein 70 (HSP70) during injury and treatment with HSP90 inhibitors. We hypothesized that administration of geranylgeranyl-acetone (GGA), an HSP70 inducer, or gefitinib (GFT), an …

Case Report: Cavitary Pneumonia In A 28 Year Old Male, Dan Zaayenga, Katelyn Courtney

Rowan-Virtua Research Day

Cavitary pneumonia can be caused by several different mechanisms. Such causes include suppurative necrosis (pyogenic lung abscess), caseous necrosis (tuberculosis), ischemic necrosis (pulmonary infarction) cystic dilatation of lung structures (ball value obstruction and Pneumocystis pneumonia) as well as malignant processes. Causes are subject to both environmental factors and host susceptibility. The most common cause of infectious process is tuberculosis with its propensity to cause extensive caseous necrosis. The potential for secondary infection after an individual develops a cavitary pneumonia is also great as it provides a shelter for various pathogens the flourish in an environment otherwise usually well-guarded by host …

Cpap And Epistaxis: Is There A Connection In Osa Patients?, Aesha Patel

Rowan-Virtua Research Day

Nasal continuous positive airway pressure (CPAP) has become a standard form of therapy for patients with obstructive sleep apnea (OSA). There are reports of patients suffering from episodes of epistaxis within the initial few weeks of starting CPAP therapy, believed to be due to the high flow rate of air during use, nasal CPAP purportedly dries the nasal mucosa, leading to an increased risk of scabbing, ulceration, and ultimately epistaxis. This study seeks to analyze whether epistaxis is common in patients following CPAP initiation and then compare this rate of epistaxis amongst OSA patients that received upper airway stimulation (UAS) …

Post-Intensive Care Syndrome Prevention And Detection In Covid-19 Patients, Bethany Sloane Melega

Student Scholar Showcase

COVID-19 has impacts on patient health beyond the hospital. The trauma that patients, and families of patients, can experience during an admission to an intensive care unit (ICU) can last long after discharge from the ICU and the hospital in general. The psychological and physical impacts of ICU hospitalization can cause patients to experience Post Intensive Care Syndrome (PICS). PICS is the culmination of symptoms that persist after a critical illness that involve all aspects of a patient’s physical and mental well-being and can significantly affect family life and increase recovery time. Due to the strict personal-protective equipment (PPE) usage …

Activation Of Cannabinoid-2 Receptor Protects Against Pseudomonas Aeruginosa Induced Acute Lung Injury And Inflammation, Nagaraja Nagre, Gregory Nicholson, Xiaofei Cong, Janette Lockett, Andrew C. Pearson, Vincent Chan, Woong-Ki Kim, K. Yaragudri Vinod, John D. Catravas

Bioelectrics Publications

Background

Bacterial pneumonia is a major risk factor for acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). Pseudomonas aeruginosa (PA), an opportunistic pathogen with an increasing resistance acquired against multiple drugs, is one of the main causative agents of ALI and ARDS in diverse clinical settings. Given the anti-inflammatory role of the cannabinoid-2 receptor (CB2R), the effect of CB2R activation in the regulation of PA-induced ALI and inflammation was tested in a mouse model as an alternative to conventional antibiotic therapy.

Methods

In order to activate CB2R, a selective synthetic agonist, JWH133, was administered intraperitoneally (i.p.) to C57BL/6J …

Nebulizer-Based Systems To Improve Pharmaceutical Aerosol Delivery To The Lungs, Benjamin M. Spence

Theses and Dissertations

Combining vibrating mesh nebulizers with additional new technologies leads to substantial improvements in pharmaceutical aerosol delivery to the lungs across therapeutic administration methods. In this dissertation, streamlined components, aerosol administration synchronization, and/or Excipient Enhanced Growth (EEG) technologies were utilized to develop and test several novel devices and aerosol delivery systems. The first focus of this work was to improve the poor delivery efficiency, e.g., 3.6% of nominal dose (Dugernier et al. 2017), of aerosolized medication administration to adult human subjects concurrent with high flow nasal cannula (HFNC) therapy, a form of continuous-flow non-invasive ventilation (NIV). The developed Low-Volume Mixer-Heater (LVMH) …

Helper T effector cytokines implicated in asthma modulate the contractility of human airway smooth muscle (HASM) cells. We have reported recently that a profibrotic cytokine, transforming growth factor (TGF)-β1, induces HASM cell shortening and airway hyperresponsiveness. Here, we assessed whether TGF-β1 affects the ability of HASM cells to relax in response to β₂-agonists, a mainstay treatment for airway hyperresponsiveness in asthma. Overnight TGF-β1 treatment significantly impaired isoproterenol (ISO)-induced relaxation of carbachol-stimulated, isolated HASM cells. This single-cell mechanical hyporesponsiveness to ISO was corroborated by sustained increases in myosin light chain phosphorylation. In TGF-β1–treated HASM cells, ISO evoked markedly lower …
