Beyond The Clot: A Rare Case Of Extensive Dvt And Pulmonary Embolism Revealing May-Thurner Syndrome, Jorge A. Aboytes, Jose J. Loayza, Ivan Mogollon, Daniel Pena, Michelle Lopez

Research Colloquium

Introduction: Deep vein thrombosis (DVT) in young adults is uncommon and typically associated with identifiable risk factors. In cases where DVT occurs without apparent provocation, congenital anatomical anomalies should be considered. May-Thurner Syndrome (MTS), a vascular compression disorder involving the left iliac vein, is a frequently overlooked cause of iliofemoral DVT in young individuals, particularly women.

Case Presentation: A 28-year-old woman with no significant medical history presented with acute left leg swelling, pain, and discoloration, along with new-onset dyspnea and chest discomfort. She had recently transitioned to a contraceptive patch and reported reduced mobility due to fatigue. Imaging confirmed left …

Extracorporeal Rescue In Massive Pulmonary Embolism: A Case Of Chronic Thromboembolic Pulmonary Hypertension Unveiled, Kenzo Ramos, Kari Gorder

Journal of Shock and Hemodynamics

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare yet curable cause of pulmonary hypertension from unresolved pulmonary emboli. We present the case of a 48-year-old man with progressive dyspnea and leg swelling, who was found to have bilateral pulmonary emboli with right heart strain. He developed cardiac arrest during thrombectomy, requiring emergent veno-arterial extracorporeal membrane oxygenation (V-A ECMO). Further evaluation revealed acute emboli superimposed on CTEPH. After incomplete thrombectomy and persistent instability, he underwent successful pulmonary endarterectomy with ECMO decannulation, leading to recovery of right ventricular function and discharge in stable condition. This case illustrates that previously unrecognized CTEPH may …

From Villi To Alveoli: Lung Involvement In Celiac Disease – A Narrative Review, Mateusz Marzec, Patrycja Cecha

Journal of Community Hospital Internal Medicine Perspectives

Background:

Celiac disease (CD) is a chronic, immune-mediated enteropathy triggered by gluten that affects about 1% of the population and may present with extraintestinal manifestations. Pulmonary complications are considered rare and are poorly characterized. Lane-Hamilton syndrome is the best described lung manifestation, but data suggests a broader spectrum of respiratory involvement.

Methods:

We performed a narrative review with structured search strategy of PubMed and Embase (January 1, 1970 – December 1, 2025) using the terms celiac/coeliac and lung, pulmonary, respiratory, hemoptysis, hemosiderosis, alveolar hemorrhage, interstitial lung disease, alveolitis, bronchiectasis …

Department of Medicine Faculty Papers

Objectives: The objective of this study is to examine the relationship between fluoroquinolone exposure and pneumothorax risk in patients hospitalized with pneumonia.

Methods: This retrospective cohort study used the TriNetX US Collaborative Network. We defined two mutually exclusive cohorts of hospitalized adults based on exposure to antibiotic classes commonly used to treat community acquired pneumonia: fluoroquinolone (ciprofloxacin, moxifloxacin, levofloxacin, and ofloxacin) versus nonfluoroquinolone (amoxicillin, azithromycin, ceftriaxone, and doxycycline). Patients with connective tissue disorders were excluded. The primary outcome was the occurrence of pneumothorax within 60 days. We used Cox proportional hazards regression to estimate hazard ratios (HRs) adjusted for demographics, …

BACKGROUND: Severe and difficult to treat asthma in children is a complex condition causing significant morbidity and associated healthcare costs. While treatment guidelines exist for severe asthma, optimal treatment approaches for the pediatric population are less well established. Furthermore, best practices regarding real world management and implementation of guidelines for the severe pediatric asthma population are lacking. In order to provide care for this population, institutions around the United States have developed multidisciplinary severe pediatric asthma programs (SPAPs). In recent years, the North American Severe Pediatric Asthma Consortium (NASPAC) was established as a mechanism for SPAPs to collaborate and share …

Assessing Clinician Preference For Redirection Of Care In Neonatal Tracheostomies, Gabriella Destefano, Alla Kushnir, Perri Donenfeld

Cooper Rowan Medical Journal

A spectrum of indications exists for the implementation of neonatal tracheostomies, ranging from short-term airway control to congenital airway anomalies. The decision to initiate long-term mechanical ventilation is multifaceted and can be influenced by factors such as physician preferences, caregivers’ attitudes, and comorbidities. It is important to have an ethical framework in place to guide the treatment of preterm neonates who may require long term mechanical ventilation. This study examines physician perspectives on the ethics of neonatal tracheostomy, focusing on the treatment of infants with bronchopulmonary dysplasia. A mixed methods study, consisting of demographic information and 5 clinical vignettes centering …

Beidas, Scott D. Halpern

College of Health Professions Faculty Papers

BACKGROUND: "Nudges" embedded in the electronic health record (EHR) facilitate desired decisions while preserving autonomy and may provide a scalable strategy to overcome the common implementation barrier of lack of knowledge about a best practice. We sought to test whether EHR-based nudges targeting two intensive care unit (ICU) clinician groups would safely increase evidence-based use of low tidal volume ventilation.

METHODS: We performed a stepped-wedge, cluster randomized, hybrid type 3 effectiveness-implementation trial in 12 ICUs from February 2021 to May 2023 to test three nudges targeting clinicians responsible for order entry and respiratory therapists responsible for operationalizing orders and documentation. …

Qualitative Beta-2-Adrenoceptor Signaling In The Regulation Of Human Airway Epithelia Mucin And Cytokine Production, Fred Graumuller, Diana Cervantes, Tung O. Chan, Niccolette Schaunaman, Dominic R. Villalba, Burton F. Dickey, Julia K. L. Walker, Hong Wei Chu, Raymond B. Penn

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

BACKGROUND: Numerous in vivo studies have demonstrated beta-2-adrenoceptor (β2AR) -agonism as permissive in the development of allergic lung inflammation, and have implicated the arrestin-dependent signaling arm of the β2AR in mediating this effect. However, the specific cell type(s) mediating β2AR regulation of allergic lung inflammation remain unestablished.

METHODS: To explore the potential contribution of airway epithelia in this phenomenon, we compared the ability of ractopamine (RP), recently identified as a Gs-biased beta-agonist, to that of the unbiased/balanced beta-agonist albuterol (ALB), on IL-13-stimulated mucin and cytokine production in human airway epithelia cultures in air-liquid interface (HAE).

RESULTS: ALB, which activates both …

Ecmo As A Bridge To Lung Transplant For Refractory Rapidly Progressive Interstitial Lung Disease, Matthew Moritz, Omar Pandhair

Books, Presentations, Posters, Etc.

Anti-melanoma differentiation-associated gene 5 (MDA-5) antibody is most frequently associated with dermatomyositis with various degrees of clinical manifestations including rapidly progressive interstitial lung disease (RP-ILD), inflammatory arthritis, vasculopathy, and other cutaneous findings. Clinically amyopathic dermatomyositis (CADM) is frequently associated with RP-ILD and has high mortality rates. Here we present a case of anti-MDA5 associated RPILD but without other features of dermatomyositis that did not respond to standard immunosuppressive therapy. A 41-year-old woman with recently diagnosed interstitial lung disease and polyarthritis previously on methotrexate presented with progressive dyspnea and worsening hypoxemic respiratory failure. She was previously admitted for respiratory failure two …

Pulmonary Pseudomyxoma Peritonei, Hannah Kirk, Do, Omar Pandhair

Books, Presentations, Posters, Etc.

Introduction: Pseudomyxoma peritonei (PMP) is an intra -abdominal cancer occurring in one to four out of one million patients. It begins as a mucinous adenocarcinoma of the appendix that implants on other peritoneal surfaces, spreading into gelatinous ascites. Treatment consists of hyperthermic intraperitoneal chemotherapy (HIPEC) and cytoreductive surgery (CRS). Extra -abdominal metastases are rare. We present the case of a patient who underwent treatment for PMP and was found to have lung nodules over a decade later. Case Presentation: A 73 -year -old woman with pseudomyxoma peritonei presented to the emergency department with progressive dyspnea and unintentional weight loss. Twenty …

Hyperglycemia And Mycoplasma Pneumoniae Cards Toxin Impacts On Lung Epithelial And Fibroblast Injury And Recovery, Alejandra Y. Delgado, Naila Villagomez, Shuri Magdalene

Posters - 2026

Mycoplasma pneumoniae CARDS toxin induces cytotoxicity and inflammation in lung epithelial cells²·¹⁰·¹¹, while hyperglycemia independently elevates ROS and disrupts fibroblast repair¹·⁵·⁸, contributing to the heightened respiratory infection severity seen in diabetic patients¹. However, the interaction between hyperglycemic conditions and CARDS toxin-induced lung injury remains unexplored.

This study investigates how increasing high-glucose (HG) pre-conditioning modifies CARDS toxin-induced injury and recovery in A549⁶ and IMR-90⁷ cells compared to normal glucose (NG ≈ 5mM) controls. We hypothesized that increasing glucose pre-conditioning concentrations would produce a dose-dependent increase in CARDS toxin-induced oxidative stress¹² and inflammatory cytokine production¹⁵ in IMR-90 and A549 compared with normal …
