IMPORTANCE: In-hospital cardiac arrest (IHCA) is a significant public health burden. Rates of return of spontaneous circulation (ROSC) have been improving, but the best way to care for patients after the initial resuscitation remains poorly understood, and improvements in survival to discharge are stagnant. Existing North American cardiac arrest databases lack comprehensive data on the post-resuscitation period, and we do not know current post-IHCA practice patterns. To address this gap, we developed the Discover In-Hospital Cardiac Arrest (Discover IHCA) study, which will thoroughly evaluate current post-IHCA care practices across a diverse cohort.

OBJECTIVES: Our study collects granular data on post-IHCA …

A 72-Year-Old Man With Acute Lung Injury And Anti-Melanoma Differentiation-Associated Gene 5 Antibody: A Case Report, Irakli Lemonjava, Jose Manuel Martinez Manzano, Sahar Sultan, Rekha Bhat, Corrado Minimo, Zurab Azmaiparashvili, Sadia Benzaquen

Einstein Health Papers

Anti-melanoma differentiation-associated gene 5 antibody (anti-MDA-5 Ab) is associated with amyopathic dermatomyositis (DM). These patients are particularly at high-risk for developing acute and rapidly progressive interstitial lung disease (ILD). Given the lack of muscle-related symptoms, along with its sudden onset and rapid clinical progression, the diagnosis of anti-MDA-5 Ab + ILD represents a challenge for clinicians. Even after the diagnosis is established, prognosis remains dismal owing to a hyperinflammatory state, mimicking cytokine storm, commonly refractory to potent immunosuppressive therapy. Hence, we present an elderly African American man who developed acute and rapidly progressive ILD in the setting of positive anti-MDA5 …

Background

• Surgery is the primary form of definitive treatment for early-stage lung cancer.
• Poor lung function before surgery places patients at high risk of pulmonary complications after resection.
• Surgeons evaluate patient fitness for surgery using pulmonary function tests (PFTs) to calculate the predicted postoperative PFT (ppoPFT).
• Conventional ppoPFT calculations assume homogeneous lung function, which can be inaccurate.
• 4DCT-ventilation is a novel lung function imaging modality developed in radiation oncology that uses 4DCT data to calculate high-resolution ventilation maps.

A Follow-Up To Implementing A Sizing Chart For Nasal Cannula Placement To Decrease Associated Pressure Ulcers In Infants, William F. Bucher, Rrt-Nps

Division of Pulmonary, Allergy, and Critical Care Medicine Posters

Background

The Joint commission definition of a “Pressure Ulcer” is a broader term that includes decubitus ulcers, but also includes any ulcerations associated with pressure. In 2015, over a three-month period, the Intensive Care Nursery (ICN) at Thomas Jefferson University Hospital had five patients who developed pressure ulcers due to placement of an improper size nasal cannula being used for that patient. Infant nasal cannulas are typically classified as being for micro premature, premature, neonate, infant, and intermediate infant size patients. To this day, there is no instruction by most manufactures for fitting a nasal cannula to the actual size …

Bronchoalveolar Lavage Neutrophils And Matrix Metalloproteinase-9 In Sarcoidosis Clinical Phenotypes: Implications For Tissue Remodeling Leading To Pulmonary Fibrosis, Rafael L. Perez, Md, Jeff Ritzenthaler, E. Torres-Gonzalez, Prarthna Chandar, Md, Daniel Kramer, Md, Jesse Roman, Md

Division of Pulmonary, Allergy, and Critical Care Medicine Posters

Introduction

Pulmonary sarcoidosis may resolve or progress to advanced stages. Increased lung neutrophils obtained by bronchoalveolar lavage are found in advanced pulmonary sarcoidosis. Persistence of a neutrophilic alveolitis has been postulated to result in tissue injury and remodeling that leads to fibrosis and clinical features of advanced disease. Since neutrophils are a source of matrix-degrading proteins like matrix metalloproteinases (MMPs), we hypothesized that PMNs promote disease progression through the release of MMPs. This work explores the relationship between lung neutrophils and MMP9 levels and activity and how they are associated with sarcoidosis clinical phenotypes.

Diagnostic And Therapeutic Challenge: A Case Of Right Ventricular Thrombus, Angad Bedi, Muhammad Sabri, Prerana Sevella, Hussam Al Hennawi, Gregory Pirolli

Abington Jefferson Health Papers

Right ventricular thrombus is a rare finding found in 4% of people diagnosed with pulmonary embolism. Although right ventricular thrombi are usually associated with atrial fibrillation, deep venous vein thrombi, or intracardiac procedures, isolated right ventricular thrombi are rare. Right ventricular thrombus has also been reported in patients with right ventricular infarction, as hypokinesis of the right ventricle causes blood stasis and promotes thrombosis as per Virchow’s triad. However, we present a case of isolated RV thrombus in a patient without evidence of deep vein thrombosis or right ventricular hypokinesis who presented with dyspnea on exertion.

Racial Disparities Among Predicted Bronchopulmonary Dysplasia Risk Outcomes In Premature Infants Born <30 Weeks Gestation, Priyanka Patel, Andrew Ellefson, David A. Paul

Department of Pediatrics Faculty Papers

Background and Objective: There is extensive literature to support eliminating race-based risk stratification. The National Institute of Child Health and Human Development (NICHD) calculator, used to predict risk of bronchopulmonary dysplasia (BPD), includes race as a variable. We sought to investigate how utilizing race in determination of risk for BPD may lead to inequitable care.

Methods: The study included a retrospective cohort of infants born <30 weeks gestation between January 2016 and February 2022. The primary outcome was the difference in predictive risk of BPD for non-Hispanic Black compared to non-Hispanic White infants. The secondary outcome was the disparity in theoretical administration of post-natal corticosteroids when the calculator was applied to the cohort. Analysis included paired T-tests and Chi-Square.

Results: Of the 273 infants studied, 154 were non-Hispanic Black (56%). There was no difference between the groups in gestation or respiratory support on day of life (DOL) 14 or 28. …

A Case Report Of Pneumoretroperitoneum From Blunt Trauma In A Patient With Chronic Obstructive Pulmonary Disease, Annemarie Daecher, Brittany Hartman, James Krueger

Einstein Health Papers

Introduction: Pneumomediastinum is a rare complication of blunt traumatic injury and is thought to be due to the Macklin effect, a pathophysiologic process comprised of three steps: alveolar rupture secondary to blunt injury; air dissecting along bronchovascular sheaths; and spread of pulmonary interstitial edema into the mediastinal space. Pneumomediastinum is rarely associated with pneumoretroperitoneum.

Case Report: We present a case of a patient who suffered a cardiac arrest after a fall during a chronic obstructive pulmonary disease exacerbation, leading to pneumoretroperitoneum.

Conclusion: This case highlights the complications that can arise from blunt trauma and how underlying lung pathology can worsen …

Idiopathic Pulmonary Fibrosis And Lung Cancer: Future Directions And Challenges, Ahmad Abu Qubo, Jamil Numan, Juan Snijder, Maria Padilla, John H.M. Austin, Kathleen M. Capaccione, Monica Pernia, Jean Bustamante, Timothy O’Connor, Mary M. Salvatore

Einstein Health Papers

Idiopathic pulmonary fibrosis (IPF) is a progressive disease of pulmonary scarring. New treatments slow disease progression and allow pulmonary fibrosis patients to live longer. Persistent pulmonary fibrosis increases a patient’s risk of developing lung cancer. Lung cancer in patients with IPF differs from cancers that develop in the non-fibrotic lung. Peripherally located adenocarcinoma is the most frequent cell type in smokers who develop lung cancer, while squamous cell carcinoma is the most frequent in pulmonary fibrosis. Increased fibroblast foci in IPF are associated with more aggressive cancer behaviour and shorter doubling times. Treatment of lung cancer in fibrosis is challenging …

Is Nippv Superior To Cpap In Maintaining Targeted Oxygen Saturation Ranges In Preterm Infants On Moderate Non-Invasive Respiratory Support?, Clifford Hegedus, William F. Bucher, Bs, Rrt-Nps, David Carola, Zubairul Aghai

Division of Pulmonary, Allergy, and Critical Care Medicine Posters

Background: Non-invasive positive pressure ventilation (NIPPV) and continuous positive airway pressure (CPAP) are non-invasive respiratory supports commonly used in preterm infants. There is conflicting data on the superiority between these two modes of non-invasive respiratory support. The objective of this study was to determine if oxygen saturation is more within the target range on NIPPV compared to CPAP using the data from histograms.

Methods: Retrospective analysis of premature neonates (< 1500 grams, gestational age < 30 weeks) admitted to the NICU for which oxygen saturation histogram data was available one day before and after the transition between NIPPV and CPAP. FiO2 at the time of data collection was greater than 21 percent. This histogram data, the percentage of time spent in certain SpO2 ranges, was compared before and after the de-escalation from NIPPV to CPAP or escalation from CPAP to NIPPV. FiO2 was additionally compared between the two modes of respiratory support.

Results: A total of 26 infants were included. The median gestational age was 25.5 weeks and the median weight of the infants was 792 grams. Among the 26 infants, there …
