Chronic obstructive pulmonary disease remains a challenging epidemic across the United States. This serious illness impacts nearly twice as many individuals in the rural area compared with urban counterparts. As the disease progresses, the symptom burden and needs of the patient and caregivers escalate. Access gaps to services, such as hospice and palliative care, and the social determinants of health found in Appalachia may lead to marginalization and social injustice. Defined as the condition of being peripheralized based upon one's social margins of identity, associations, and/or environment, marginalization impacts health outcomes and quality of life. This article explores the triple threat of marginalization for patients with chronic obstructive pulmonary disease living in rural Appalachia. By recognizing marginalization and designing initiatives to reduce the impact, hospice and palliative care nurses serve as advocates and leaders to influence systemic change through partnerships with key policymakers and legislators.

In this paper, we present a new computational framework for the simulation of airway resistance, the fraction of exhaled nitric oxide, and the diffusion capacity for nitric oxide in healthy and unhealthy lungs. Our approach is firstly based on a realistic representation of the geometry of healthy lungs as a function of body mass, which compares well with data from the literature, particularly in terms of lung volume and alveolar surface area. The original way in which this geometry is created, including an individual definition of the airways in the first seven generations of the lungs, makes it possible to consider the heterogeneous nature of the lungs in terms of perfusion and ventilation.

Background: Nasal high flow (NHF) has been proposed to sustain high intensity exercise in people with COPD, but we have a poor understanding of its physiological effects in this clinical setting.
Research Question: What is the effect of NHF during exercise on dynamic respiratory muscle function and activation, cardiorespiratory parameters, endurance capacity, dyspnoea and leg fatigue as compared to control intervention.
Study Design And Methods: Randomized single-blind crossover trial including COPD patients.

Age-related lung function decline is associated with small airway closure and gas trapping. The mechanisms which cause these changes are not fully understood. It has been suggested that COPD is caused by accelerated ageing.
