The lung Composite Allocation Score (CAS) was implemented in 2023, and has shown to increase lung transplant rates and lower waitlist mortality. Host Alice Gallo de Moraes, MD, of the Mayo Clinic, interviews experts Mary Raddawi, MD, of Columbia University Irving Medical Center, and Amy Skiba, of the Lung Transplant Foundation, on the importance of CAS and how it has changed outcomes for lung transplant patients. 

 This Giving Tuesday, we have a special episode of the ATS Breathe Easy podcast. Wildfires are a destructive phenomenon that decimates communities, infrastructure, and wildlife. But wildfires and wildfire smoke are also severely damaging to human health, especially for those who have lung disease. Stacie Reveles, of the Cystic Fibrosis Research Institute, talks about her struggles living in wildfire country with a child who has cystic fibrosis. She discusses everything from dealing with medications and evacuations, the mental toll, and the importance of continued research into these illnesses. Air Health Our Health podcast creator Erika Moseson, MD, MA, of Legacy Health in Oregon hosts.

 Smoking is the main risk factor for COPD in the United States and many other countries. However, it is important to recall that there are other causes of COPD, from birth experiences to environmental exposures. COPD expert Meilan K. Han MD, MS, University of Michigan Health, discusses non-smoking causes of COPD, what patients can do to manage their symptoms, and how clinicians and communities can help. Air Health Our Health podcast creator Erika Moseson, MD, MA, of Legacy Health in Oregon hosts.

Exercise is key for managing symptoms for COPD patients. On World COPD Day, host Amy Attaway, MD, Cleveland Clinic, talks to Rachel Evans, MD, University of Leicester, and Russell Winwood, a patient advocate known as the "COPD Athlete", about how exercise can improve patient outcomes. They also discuss the annual Big Baton Pass, an international COPD awareness event, the importance for pulmonary rehabilitation, and the community built around COPD advocacy and support for patients.

As new studies uncover better treatments and practices, it is important to develop new clinical practice guidelines to ensure patients receive the best care. Julio A. Ramirez, MD, Norton Healthcare and University of Louisville, and co-lead of the guideline panel, dives into the process of creating an update clinical practice guideline for community-acquired pneumonia with host Eddie Qian, MD, Vanderbilt University Medical Center, as well as the importance to the medical community and patients when making key care decisions.

 This episode was created in collaboration with, and first posted on, The Itch podcast.

Mucus plugging is a challenge in asthma care. It’s thick, sticky mucus that blocks the airways and doesn’t respond to regular inhalers. Even when inflammation improves, these plugs can lower lung function, limit how well medicine works, and make asthma harder to control.

In this episode, The Itch breaks down the study: “Effect of Dupilumab on Mucus Burden in Patients with Moderate-to-Severe Asthma,” published Oct. 28, 2025. The analysis looks at whether dupilumab (Dupixent), a biologic that blocks IL-4 and IL-13, can lower mucus burden and improve lung function, especially in people who start with a high “mucus plug score.”

 Chronic Obstructive Pulmonary Disease (COPD) is a group of lung diseases that cause airflow obstruction and other respiratory problems. There are various options for treating COPD, including the highly effective controller medication that helps improve a patient's lung function in the long-term. But as Antonio R. Anzueto, MD, professor of pulmonary and critical care at the University of Texas Health, San Antonio, explains, it is not easy for patients to use these medications. 

Listen as Dr. Anzueto and host Amy Attaway, MD, Cleveland Clinic, discuss the effectiveness of different COPD treatments, how COPD can affect other organs, and how AI might play into diagnosing COPD as technology advances.

Vaping and e-cigarettes are often incorrectly thought of as thought of as safe, but research has proven this to be untrue. They are particularly unsafe for the developing brain of children and adolescents. Laura Crotty Alexander, MD, from the University of California, San Diego, explains to host Erika Moseson, MD, MA, that not only does vaping often lead to users moving on to traditional tobacco products, but it also has a major impact on mental health and mood that could be deadly.

Learning how to perform procedures on patients is an important part of medical training, but how do programs decide what to teach? And how do they integrate the latest technology? Host Eddie Qian, MD, from Vanderbilt University Medical Center, talks to Meredith Pugh, MD, MSCI, and Kaele Leonard, MD, of Vanderbilt University Medical Center. Together, they discuss how they think about working with trainees and fellows when it comes to teaching important procedures. 

On this episode of the ATS Breathe Easy podcast, host Amy Attaway, MD, of Cleveland Clinic, continues her discussion with asthma expert Njira Lugogo, MD, of University of Michigan. They talk about collaborations in the pulmonary field, the importance of clinical trials, and career advice for those looking to join the field of pulmonology.
