Increased risk of osteoarthritis in patients with atopic disease 

Objectives To determine the incidence of osteoarthrits (OA) in patients with atopic disease compared with matched non-exposed patients.Methods We conducted a retrospective cohort study with propensity score matching using claims data from Optum’s de-identified Clinformatics Data Mart (CDM) (January 2003 to June 2019) and electronic health record data from the Stanford Research Repository (STARR) (January 2010 to… Continue reading Increased risk of osteoarthritis in patients with atopic disease 

Cannabis legalization and childhood asthma in the United States: An ecologic analysis

Cannabis use is increasing among adults with children in the home particularly in states with cannabis legalization for medical (MCL) and/or recreational use (RCL), relative to states where cannabis use remains illegal at the state level. Exposure to secondhand smoke is a key risk factor for asthma among children. The objective of the current study… Continue reading Cannabis legalization and childhood asthma in the United States: An ecologic analysis

Sputum Type 2 Markers Could Predict Remission in Severe Asthma Treated With Anti-IL-5

Biotherapies targeting IL-5 allow a tangible improvement of asthma. However, all patients do not respond the same way to these treatments. Even if high blood eosinophil counts seem to be associated with a reduction in exacerbations with treatment targeting IL-5, we lack biomarkers for the prediction of remission after these very expensive treatments.Research QuestionDoes the… Continue reading Sputum Type 2 Markers Could Predict Remission in Severe Asthma Treated With Anti-IL-5

Differential impact of low fat-free mass in people with COPD based on body mass index classifications: results from COSYCONET

BackgroundAlterations in body composition, including a low fat-free mass index (FFMI), are common in patients with chronic obstructive pulmonary disease (COPD) and occur regardless of body weight.Research questionIs the impact of low FFMI on exercise capacity, health-related quality of life (HRQL) and systemic inflammation different among COPD patients stratified in different body mass index classifications?Study… Continue reading Differential impact of low fat-free mass in people with COPD based on body mass index classifications: results from COSYCONET

Persistent Asthma Is Associated With Carotid Plaque in MESA

BackgroundAsthma and atherosclerotic cardiovascular disease share an underlying inflammatory pathophysiology. We hypothesized that persistent asthma is associated with carotid plaque burden, a strong predictor of atherosclerotic cardiovascular disease events.Methods and ResultsThe MESA (Multi‐Ethnic Study of Atherosclerosis) enrolled adults free of known atherosclerotic cardiovascular disease at baseline. Subtype of asthma was determined at examination 1. Persistent… Continue reading Persistent Asthma Is Associated With Carotid Plaque in MESA

Chest CT Findings in Marijuana Smokers

BackgroundGlobal consumption of marijuana is increasing, but there is a paucity of evidence concerning associated lung imaging findings.PurposeTo use chest CT to investigate the effects of marijuana smoking in the lung.Materials and MethodsThis retrospective case-control study evaluated results of chest CT examinations (from October 2005 to July 2020) in marijuana smokers, nonsmoker control patients, and… Continue reading Chest CT Findings in Marijuana Smokers

Association Between Aluminum Exposure From Vaccines Before Age 24 Months and Persistent Asthma at Age 24 to 59 Months

ObjectiveTo assess the association between cumulative aluminum exposure from vaccines before age 24 months and persistent asthma at age 24 to 59 months.MethodsA retrospective cohort study was conducted in the Vaccine Safety Datalink (VSD). Vaccination histories were used to calculate cumulative vaccine-associated aluminum in milligrams (mg). The persistent asthma definition required one inpatient or 2 outpatient asthma… Continue reading Association Between Aluminum Exposure From Vaccines Before Age 24 Months and Persistent Asthma at Age 24 to 59 Months

Evaluating triple ICS/LABA/LAMA therapies for COPD patients: a network meta-analysis of ETHOS, KRONOS, IMPACT, and TRILOGY studies

In some studies comparing triple with dual combination therapies in COPD there might be a possible effect of inhaler bias resulting from different inhaler devices being used in comparator arms. The aim of this study was a quantitative synthesis by considering the studies that directly compared triple ICS/LABA/LAMA vs. either dual LABA/LAMA or ICS/LABA therapies… Continue reading Evaluating triple ICS/LABA/LAMA therapies for COPD patients: a network meta-analysis of ETHOS, KRONOS, IMPACT, and TRILOGY studies

Thirdhand Exposures to Tobacco-Specific Nitrosamines through Inhalation, Dust Ingestion, Dermal Uptake, and Epidermal Chemistry

Tobacco-specific nitrosamines (TSNAs) are emitted during smoking and form indoors by nitrosation of nicotine. Two of them, N′-nitrosonornicotine (NNN) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), are human carcinogens with No Significant Risk Levels (NSRLs) of 500 and 14 ng day–1, respectively. Another TSNA, 4-(methylnitrosamino)-4-(3-pyridyl) butanal (NNA), shows genotoxic and mutagenic activity in vitro. Here, we present additional evidence… Continue reading Thirdhand Exposures to Tobacco-Specific Nitrosamines through Inhalation, Dust Ingestion, Dermal Uptake, and Epidermal Chemistry
