It remains uncertain how long pure ground-glass nodules (pGGNs) detected on low dose computed tomography (LDCT) should be followed. Further studies with longer follow-up periods are needed to determine the optimal follow-up duration for pGGNs. ⋯ Among pGGNs that remained stable for 10 years, 3.9% eventually grew, indicating that some pGGNs can grow even after a long period of stability. We suggest that pGGNs may need to be followed for more than 10 years to confirm growth.

Multidisciplinary pulmonary embolism response teams (PERTs) streamline care of adults with life-threatening pulmonary embolism (PE). Given rarity of pediatric PE, developing a clinical, educational, and research PERT paradigm is a novel and underused concept in pediatrics. ⋯ The pediatric PERT paradigm was successfully created and adopted locally. Our PERT enhanced access to experts, facilitated timely advanced therapies, and held value for low-risk PE. The University of Texas Southwestern Medical Center and Children's Health System of Texas pediatric PERT may serve as a best practice model for streamlining care for pediatric PE.

Although it is generally accepted that aerobic exercise training does not change lung structure or function, some work suggests that greater pulmonary vascular structure and function is associated with higher exercise capacity (peak oxygen consumption [Vo2peak]). ⋯ Our results suggest that pulmonary vascular structure and Dlco are independently associated with Vo2peak, regardless of severity of airflow limitation and emphysema, suggesting that these associations are not limited to COPD.
