Patients with asthma and COPD rely on inhalers to control symptoms. Yet, these products remain expensive, in part because brand-name manufacturers have obtained numerous patents on inhalers, including on their delivery devices. Recent antitrust litigation has raised questions about the boundaries of listing device patents with the US Food and Drug Administration (FDA), particularly when patents do not claim any active ingredients. ⋯ Patent and regulatory reform is needed to promote generic competition and to ensure that patients with asthma and COPD have access to affordable medications.

OSA is a common sleep-breathing disorder linked to increased risk of cardiovascular disease. Intermittent upper airway obstruction and hypoxia, hallmarks of OSA, have been shown in animal models to induce substantial changes to the gut microbiota composition, and subsequent transplantation of fecal matter to other animals induced changes in BP and glucose metabolism. ⋯ OSA-related hypoxia, but not the number of apneas/hypopneas, is associated with specific gut microbiota species and functions. Our findings lay the foundation for future research on the gut microbiota-mediated health effects of OSA.

A 53-year-old woman with no significant past medical history came to her local ED after a witnessed generalized tonic-clonic seizure. CT scan imaging of the head revealed a left frontal lobe hypodensity concerning for a mass with surrounding edema.

Idiopathic pulmonary fibrosis (IPF) is a fatal lung disease with a high burden of both pulmonary and extrapulmonary comorbidities. ⋯ The present study suggested the causal associations between IPF and certain comorbidities from a genetic perspective. Further research is needed to understand the mechanisms of these associations.
