Associations of #sleep duration with patient-reported outcomes and healthcare use in U.S. adults with #asthma

..Asthma was identified by self-report. Habitual hours of sleep duration were categorized as short (≤5), normal (6-8), and long (≥9). Multivariate regression analyses were used to examine the associations between sleep duration and patient-reported outcomes and healthcare use. Results Of the 1389 adults with asthma, 26% reported short sleep duration, 66% reported normal sleep duration, and 8% reported long sleep duration. Those with short sleep … Continue reading Associations of #sleep duration with patient-reported outcomes and healthcare use in U.S. adults with #asthma

Sputum #microbiome profiles identify severe #asthma phenotypes of relative stability at 12-18 months

..Data were available for 100 severe asthma subjects (median age: 55 yrs, 42% males). Two microbiome-driven clusters were identified, characterized by differences in asthma onset, smoking status, residential locations, percentage of blood and/or sputum neutrophils and macrophages, lung spirometry, and concurrent asthma medications (all p-values <.05). Cluster 2 patients displayed a commensal-deficient bacterial profile which was associated with worse asthma outcomes compared to cluster 1. … Continue reading Sputum #microbiome profiles identify severe #asthma phenotypes of relative stability at 12-18 months

Persistent #Asthma is Associated with Increased Risk for Incident Atrial #Fibrillation in the Multi-Ethnic Study of Atherosclerosis (MESA)

Asthma and atrial fibrillation (AF) share an underlying inflammatory pathophysiology. We hypothesized that persistent asthmatics are at higher risk for developing AF and that this association would be attenuated by adjustment for baseline markers of systemic inflammation. ..Persistent asthma was defined as asthma requiring use of controller medications. Intermittent asthma was defined as asthma without use of controller medications.. ..In risk-factor adjusted models, persistent asthmatics … Continue reading Persistent #Asthma is Associated with Increased Risk for Incident Atrial #Fibrillation in the Multi-Ethnic Study of Atherosclerosis (MESA)

Sex Steroid #Hormones and #Asthma in a Nationwide Study of U.S. Adults

Women have a higher burden of asthma than men. Although sex hormones may explain sex differences in asthma, their role is unclear.. ..Free testosterone levels in the fourth quartile were associated with lower odds of current asthma in women (odds ratio [OR] for the fourth quartile [Q4] vs. Q1, 0.56; 95% confidence interval [CI], 0.39–0.80). Given an interaction between obesity and sex hormones on current … Continue reading Sex Steroid #Hormones and #Asthma in a Nationwide Study of U.S. Adults

Fatty #Airways: Implications for #Obstructive Disease

Epidemiological studies report that overweight or obese asthmatic subjects have more severe disease than those of a healthy weight. We postulated accumulation of adipose tissue within the airway wall may occur in overweight patients and contribute to airway pathology ..BMI ranged from 15 to 45 (kg·m−2) and was greater in NFA (p<0.05). Adipose tissue was identified in the outer wall of large airways (Pbm>6 mm), but … Continue reading Fatty #Airways: Implications for #Obstructive Disease

Association of Occupational Exposure to #Disinfectants With Incidence of Chronic Obstructive #Pulmonary Disease Among US Female Nurses

Exposure to disinfectants in health care workers has been associated with respiratory health outcomes, including asthma. Weekly use of disinfectants to clean surfaces only (16 786 [22.9%] of participants exposed) and to clean medical instruments (13 899 [19.0%] exposed) was associated with COPD incidence, with adjusted hazard ratios of 1.38 (95% CI, 1.13-1.68) for cleaning surfaces only and 1.31 (95% CI, 1.07-1.61) for cleaning medical … Continue reading Association of Occupational Exposure to #Disinfectants With Incidence of Chronic Obstructive #Pulmonary Disease Among US Female Nurses

Single inhaler extrafine triple therapy in uncontrolled asthma (TRIMARAN and TRIGGER): two double-blind, parallel-group, randomised, controlled phase 3 trials

..extrafine combination of beclometasone dipropionate (BDP; inhaled corticosteroid), formoterol fumarate (FF; long-acting β 2 agonist), and glycopyrronium (G; long-acting muscarinic antagonist) with the combination of BDP with FF ..Compared with the BDP/FF group, week 26 predose FEV 1 improved in the BDP/FF/G group by 57 mL (95% CI 15–99; p=0·0080) in TRIMARAN and by 73 mL (26–120; p=0·0025) in TRIGGER, with reductions in the rate … Continue reading Single inhaler extrafine triple therapy in uncontrolled asthma (TRIMARAN and TRIGGER): two double-blind, parallel-group, randomised, controlled phase 3 trials
