The Affordable Care Act was intended to address systematic health inequalities for millions of Americans who lacked health insurance. Expansion of Medicaid was a key component of the legislation, as it was expected to provide coverage to low-income individuals, a population at greater risk for disparities in access to the health care system and in health outcomes. Several studies suggest that expansion of Medicaid can reduce insurance-related disparities, creating optimism surrounding the potential impact of the Affordable Care Act on the health of the poor. ⋯ Moreover, relative to many private plans, Medicaid is an imperfect program suffering from lower reimbursement rates, fewer covered services, and incomplete acceptance by preventive and specialty care providers. These constraints will reduce the potential impact of the expansion for patients with respiratory and sleep conditions or critical illness. Despite its imperfections, the more than 10 million low-income individuals who gain insurance as a result of Medicaid expansion will likely have increased access to health care, reduced out-of-pocket health care spending, and ultimately improvements in their overall health.

Because the frequency of major risk factors for respiratory diseases (e.g., tobacco use) differs across demographic groups (defined by socioeconomic status, race/ethnicity, sexual orientation, health care access, occupation, or other characteristics), health disparities are commonly encountered in pediatric and adult pulmonary, critical care, and sleep medicine. As part of its policy on respiratory health disparities, the American Thoracic Society (ATS) Executive Committee created a Health Equality Subcommittee of the Health Policy Committee, with an initial mandate of defining respiratory health equality and, as a subsequent task, providing recommendations to the ATS leadership as to how our society may help attain such equality in the United States. After receiving input from the ATS assemblies and committees, the subcommittee developed this document on respiratory health equality. ⋯ Attainment of respiratory health equality requires the ending of respiratory health disparities, which can be achieved only through multidisciplinary efforts to eliminate detrimental environmental exposures while promoting a healthy lifestyle, implementing all components of high-quality health care (prevention, screening, diagnosis, and treatment), and conducting research that will lead to better prevention and management of respiratory diseases for everyone. The ATS recognizes that such efforts must include all stakeholders: members of society at large, governmental and nongovernmental organizations, and other professional societies. The ATS urges all of its members and those of sister societies to work to achieve this laudable goal.

The mechanism by which viruses cause exacerbations of chronic airway disease and the capacity of patients with cystic fibrosis (CF) to respond to viral infection are not precisely known. ⋯ We conclude that virus-induced exacerbations of CF are associated with immune responses tailored to specific infections. Influenza induced a more potent response consisting of inflammation, whereas RV infection had a pronounced effect on chemokine expression. As far as we are aware, this study is the first to compare specific responses to different viruses in live patients with chronic airway disease.

Measurement of sputum or blood eosinophils may allow identification of a severe eosinophilic asthma population responsive to mepolizumab. ⋯ A single measurement of 150/μl or greater predicted the average of subsequent measurements being 150/μl or greater in 85% of this population. Using an average of multiple measurements only marginally increases the sensitivity. Sputum eosinophils did not predict treatment response with mepolizumab.

Technological advances have improved the ability of bronchoscopists to access peripheral pulmonary lesions for tissue sampling. Radial probe endobronchial ultrasound (EBUS) provides real-time feedback to guide biopsies of peripheral lesions, thereby potentially improving diagnostic yield over conventional bronchoscopy. ⋯ Radial probe EBUS can be used to guide biopsy during peripheral bronchoscopy. This technique provides real-time ultrasound-based confirmation of target lesion localization prior to biopsy. Using radial probe EBUS, the vast majority of peripheral pulmonary nodules can be identified. Radial EBUS probe position relative to the target lesion significantly affects the diagnostic yield.
