RATIONALE: Accelerated decline in lung function is associated with incident COPD, hospitalizations and death. However, identifying this trajectory with longitudinal spirometry measurements is challenging in clinical practice. OBJECTIVE: To determine whether a proteomic risk score trained on accelerated decline in lung function can assess risk of future respiratory disease and mortality. METHODS: In CARDIA, a population-based cohort starting in young adulthood, longitudinal measurements of FEV1 percent predicted (up to six timepoints over 30 years) were used to identify accelerated and normal decline trajectories...

Cystic fibrosis is a genetic disease caused by mutations in the cystic fibrosis transmembrane conductance regulator ( CFTR ) gene. While cystic fibrosis is a multi-organ disease, the leading causes of morbidity and mortality are related to progressive lung disease. Current understanding of the effects of the broad spectrum of CFTR mutations on CFTR function has allowed for the development of CFTR modulator therapies. Despite the remarkable impact that these therapies have had, there remains a significant proportion of people with cystic fibrosis (estimated at 10-15% of the global cystic fibrosis population) who are genetically ineligible for, or intolerant to, current CFTR-targeting therapies and whose therapeutic needs remain unmet...

Rationale: Chronic obstructive pulmonary disease (COPD) is associated with increased risk of cardiovascular and cardiopulmonary events. In the Phase III, 52-week ETHOS trial (NCT02465567), triple therapy with budesonide/glycopyrrolate/formoterol fumarate (BGF) reduced rates of moderate/severe exacerbations and all-cause mortality versus dual therapy with glycopyrrolate/formoterol fumarate (GFF) or budesonide/formoterol fumarate (BFF). However, the effect of BGF on cardiovascular events versus GFF remains unevaluated...

RATIONALE: Idiopathic pulmonary fibrosis (IPF) is a fatal lung disease for which current treatment options only slow clinical progression. Previously, we identified a subset of patients with IPF with an accelerated disease course associated with fibroblast expression of Toll-Like Receptor 9 (TLR9) mediated by interactions with its ligand mitochondrial DNA (mtDNA). OBJECTIVES: We aimed to show that TLR9 activation induces fibroproliferative responses that are abrogated by its antagonism by using two commercially-available indirect inhibitors and a proprietary, selective direct small molecule inhibitor...

RATIONALE: Uncertainty remains regarding the risks associated with single dose use of etomidate. OBJECTIVES: To assess use of etomidate in critically ill patients and compare outcomes for patients who received etomidate versus ketamine. METHODS: We assessed patients who received invasive mechanical ventilation (IMV), admitted to an ICU in the Premier Healthcare Database, 2008-2021. The exposure was receipt of etomidate on the day of IMV initiation and the main outcome was hospital mortality...
