Thick, viscous respiratory secretions are a major pathogenic feature of COVID-19, but the composition and physical properties of these secretions are poorly understood. We characterized the composition and rheological properties (i.e., resistance to flow) of respiratory secretions collected from intubated COVID-19 patients. We found the percentages of solids and protein content were greatly elevated in COVID-19 compared with heathy control samples and closely resembled levels seen in cystic fibrosis, a genetic disease known for thick, tenacious respiratory secretions. DNA and hyaluronan (HA) were major components of respiratory secretions in COVID-19 and were likewise abundant in cadaveric lung tissues from these …

The New Ropanasuri Journal of Surgery

The Coronavirus disease 2019 (COVID-19) pandemic impacts pulmonary cancer management since it shares similar clinical features and creates fear among patients to visit hospitals due to possible in-hospital disease transmission. We report a patient who presented with a rare case of a pulmonary neuroendocrine tumor with an ocular involvement, which, unfortunately, experienced a delay in diagnostics. The first hospitalization was due to superior vena cava syndrome, pleural and pericardial effusions, and swollen left eye. The patient was diagnosed with pulmonary cancer, released after the symptoms were relieved, and expected to visit a referral hospital for further diagnostics and treatments. The …

Physics-Informed Machine Learning For Estimating Pulmonary Perfusion From Non-Contract 4dct, Y Liu, A Nowacki, R Castillo, Y Vinogradskiy, G Nair, C Stevens, E Castillo

Conference Presentation Abstracts

Purpose: Novel methods have been developed for functional avoidance that proposes to use 4DCT to derive lung ventilation and perfusion images. Previous methods for quantifying lung perfusion on non-contrast 4DCT rely either on HU-based physical models or black-box deep learning models. While deep learning typically achieves higher accuracies in image processing tasks, physical models provide a rationale for model predictions. The purpose of this study is to introduce a biophysics-informed machine learning method for estimating pulmonary perfusion from noncontrast 4DCT. Our approach is designed to combine the predictive power of neural networks with the interpretability of physical modeling, with the …

Quantifying Copd Disease Severity With Ct-Derived Perfusion Imaging, A Nowacki, G Nair, Y Liu, C J. Galban, C Stevens, E Castillo

Conference Presentation Abstracts

Purpose: CT-derived perfusion (CTP) is a novel image processing modality that quantifies pulmonary perfusion from non-contrast inhale/exhale CT image pairs. While existing imaging markers for COPD primarily depend on morphological features or HU thresholding, CTP provides a quantitative marker of blood flow and has been shown to identify disease progression prior to the appearance structural abnormalities. In this study, we assess the potential utility of CTP as a disease severity marker for COPD. Methods: CTP was computed from high-resolution inhale-exhale CT scans for 785 patients with a Global Initiative for Obstructive Lung Disease (GOLD) score ranging from 0 to 4 …

Diffuse Alveolar Hemorrhage Due To Hydralazine-Induced Lupus, P Boshara, E Calvo-Ayala

Conference Presentation Abstracts

Introduction: Hydralazine is a known cause of drug-induced lupus. Rarely, it’s been reported to cause major organ-threatening complications, manifesting as kidney disease and CNS involvement. It’s also been associated with ANCA-positive vasculitis primarily involving the kidney, with uncommon pulmonary complications. We report a unique case of hydralazine-induced lupus presenting as diffuse alveolar hemorrhage (DAH) in the absence of renal disease or ANCA-positive vasculitis, which was successfully treated with systemic steroid monotherapy. Case description: The patient is an 86 year-old female with a history of chronic immune thrombocytopenia who presented to the hospital due to one week of dyspnea and hemoptysis. …

Impact Of Serum Igg Levels Against Sars-Cov-2 On Clinical Outcomes For Hopitalized Covid Patient, Bipin Ghimire, Bijaya Thapa, Nishant Aggarwal, Luai Madanat, Melinda Sager, Daniel O'Connor, Alexandra Halalau

Conference Presentation Abstracts

BACKGROUND: The SAR-CoV-2 pandemic continues to negatively impact the healthcare system globally with over 800,000 deaths in the United States and millions more worldwide. The cases are rising despite availability of vaccines. For most immunocompetent patients these vaccines will generate a humoral response and also a memory T-cell response. Few if any studies have reported data that measure anti-spike IgG titers and also correlate those titers with clinical outcomes in the instance of breakthrough infection.

METHODS: We conducted a pilot prospective observational clinical study enrolling 30 immunocompetent patients who were admitted with a positive SARS-CoV-2 PCR. Leftover blood from admission …

A Case Report Of Pulmonary Actinomycosis: A Diagnostic Quagmire, Sarah Akbani, Aderinsola O. Ademiluyi, Jonathan Dean, Vinita Mathur

Advances in Clinical Medical Research and Healthcare Delivery

The implications of misdiagnosis can be drastic, especially when the correct diagnosis is treatable. Pulmonary actinomycosis is one of the complications of infection with actinomyces, an anaerobic gram-positive organism that is usually found as a part of the normal flora in the human body infection. It is a very rare disease and is frequently mistaken with other diagnoses owing to its nonspecific presentation. In this report, we present a 67-year-old male with a mass like lesion on a CT scan of his chest that was done due to progressively worsening productive cough, weight loss and fatigue. These symptoms could have …

Antimicrobial Stewardship Meets Transitions Of Care: Defining Length Of Therapy For Community-Acquired Pneumonia (Cap), Christopher Whitman, Sarah E. Moore, Matthew Song, Brian C. Bohn, Ashley M. Wilde

The University of Louisville Journal of Respiratory Infections

Introduction: Hospital-based antimicrobial stewardship efforts have traditionally focused on inpatient settings. Antibiotic prescribing at discharge is often an overlooked area of focus for antimicrobial stewardship programs. Discharge prescribing optimization is necessary to combat antibiotic overuse.

Methods: This was an observational, retrospective cohort study at a four–adult community hospital system. Four hundred adult patients admitted with community-acquired pneumonia and discharged with antibiotics were included. The primary outcome was overall (inpatient and discharge) antibiotic length of therapy. The secondary outcome was percentage of patients discharged on a fluoroquinolone who had not received one in the hospital. Descriptive statistics were utilized.

Results: The …

Diaphragmatic Adjacencies: Pulmonary Embolism Presenting As Abdominal Pain, Joseph Piraneo, Christopher Schwartz, Russell Mordecai

Rowan-Virtua Research Day

Pulmonary embolism is a common yet potentially life-threatening diagnosis that should not be missed in the Emergency Department. Common presenting symptoms include dyspnea, pleuritic chest pain, cough, hemoptysis, syncope or pre-syncope. Less often, however, presenting symptoms can include abdominal pain. A clinician should recognize that pain adjacent to the diaphragm (including the lower chest and upper abdomen), can be secondary to underlying pathology either above or below the diaphragm. Here we describe an unusual case of pleuritic, post-prandial, right upper quadrant abdominal pain that was a result of pulmonary embolism.

Syncope Masquerading As Pulmonary Embolism, Melissa Itidiare Locke, Andrew Caravello, Melanie Angelo, Andrew Vasta

Rowan-Virtua Research Day

Syncope is a clinical syndrome that occurs due to a period of inadequate cerebral blood flow that cause a transient loss of consciousness that usually resolves within 8-10 seconds) [1] Our case demonstrates a 56-year-old female who experienced syncope for the first time. The patient had an unwitnessed fall and subsequently had imaging studies performed. A discovery of a Sub-Massive Pulmonary embolism was revealed.

Lung Hernia: An Uncommon Cause Of Pleuritic Chest Pain, Brittany Fera

Rowan-Virtua Research Day

Lung hernia is a rare but important consideration in the differential diagnosis of chest pain in patients with recent thoracic trauma or a history of thoracic surgery. Patients who undergo an anterior approach to thoracotomy, as was the case with our patient, are at a higher risk for developing lung herniation as a result of inherent anatomical weakness and wider intercostal spaces anteriorly and inferiorly.

A Study To Compare Baseline Functional Residual Capacity And Forced Vital Capacity As Predictors Of Mortality And Hospitalization In A Cohort Of Mild To Moderate Interstitial Lung Disease, Olga R. Gomez Rojas, Ehsun Naeem, Filip Ionescu, Edward Castillo, Girish B. Nair

Posters

Forced Vital Capacity (FVC) is a common parameter used to assess disease progression in patients with Interstitial lung disease (ILD) and acts as a surrogate for mortality. Previous studies suggest Functional Residual Capacity (FRC) may be an earlier predictor of disease progression in ILD. In this study, we compared predictive ability of baseline FRC to FVC to predict one-year-mortality and respiratory related hospitalization in patients with mild to moderate ILD
