Rationale: Higher indoor particulate matter (PM) concentrations are linked with increased asthma morbidity. Dietary intake of fatty acids, also outcomes, may influence this relationship. Objectives: To determine the relationship between omega-3 and omega-6 acid pediatric morbidity, association strength indoor, PM-related symptoms, albuterol use, systemic inflammation. Methods: Analyses included 135 children enrolled in AsthmaDIET Study. At baseline, 3 months, 6 data included: week-long...

On December 18, 2020, the FDA approved osimertinib as adjuvant therapy in patients with non-small cell lung cancer (NSCLC) whose tumors have EGFR exon 19 deletions or 21 (L858R) mutations, detected by an FDA-approved test. The approval was based on ADAURA study, which 682 NSCLC were randomized to receive (n = 339) placebo 343). Disease-free survival (DFS) overall population (stage IB-IIIA) improved for who received osimertinib, HR of 0.20; 95% confidence interval (CI), 0.15-0.27; P < 0.0001....

Omega-3 fatty acids, including alpha-linolenic acid (ALA), eicosapentaenoic (EPA), docosahexaenoic (DHA) and derivatives, play a key role in the resolution of inflammation. Higher intake has been linked to decreased morbidity several diseases, though effects on respiratory diseases like COPD are understudied. The National Health Nutrition Examination Survey (NHANES), with focus dietary assessment, provides unique opportunity explore relationships between omega-3 marked by inflammation United...

Background: The use of immune checkpoint inhibitor (ICI) therapy has improved outcomes for many types cancer, including primary lung cancer. With increased this therapy, immune-related adverse events (IRAE) are identified more frequently and can affect any organ system. ICI-pneumonitis varied levels severity at the time diagnosis that range from mild with nonspecific symptoms to fatal respiratory failure in severe cases. Therefore, early recognition is crucial, a multidisciplinary approach...

Abstract Introduction Obstructive sleep apnea (OSA) is a common disorder that underrecognized and associated with comorbid conditions societal impact. Health systems have directed efforts to inpatient assessment (OSA screening) identify patients at risk early treatment initiation avoid unexpected outcomes including medical emergency team activation (META) (code blue, code stroke, rapid response, reintubation). However, acceptance of positive airway pressure (PAP) therapy remains low for both...

Abstract Introduction Obstructive sleep apnea (OSA) is a common condition associated with multiple co-morbidities, however, diagnostic challenges limit its recognition. Sleep screening has improved our recognition, and Home Apnea Testing (HSAT) access to testing for OSA. The SANSA© device an FDA cleared novel HSAT patch that records 8 essential physiologic parameters (pulse oximetry, actigraphy, ECG-based heart rate rhythm, respiratory effort, chest movement, snoring, body position)...

Abstract Study Objectives Sleep is an important dimension in the care of chronic obstructive pulmonary disease (COPD), but its relevance to exacerbations unclear. We wanted assess whether sleep quality as measured by Pittsburgh Quality Index (PSQI) associated with increased risk COPD and does this differ socio-environmental exposures. Methods included 1647 current former smokers spirometrically confirmed from SPIROMICS cohort. assessed incidence rate ratios for exacerbation using...

Nicotine from cigarette smoke is a biologically active molecule that has pleiotropic effects in the airway, which could play role smoking-induced lung disease. However, whether nicotine and its metabolites reach sustained, physiologically relevant concentrations on airway surfaces of smokers not well defined. To address these issues, nicotine, cotinine, hydroxycotinine were measured by mass spectrometry (MS) supernatants induced sputum obtained participants subpopulations intermediate...

Omega-3 polyunsaturated fatty acids (PUFAs) have been associated with systemic anti-inflammatory responses. Dietary intake of omega-3 PUFAs eicosapentaenoic acid (EPA) and docosahexaenoic (DHA) has also lower chronic obstructive pulmonary disease (COPD) morbidity using self-report food frequency questionnaires.
