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 …

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 …

Prenatal antibiotic exposure, asthma and the atopic march: A systematic review and meta-analysis
BackgroundAntibiotic use during pregnancy may increase the risk for asthma in children. We performed a meta-analysis assessing prenatal antibiotic exposure and the risk for childhood wheeze or asthma, as well as for diseases associated with the atopic march. MethodsA systematic literature search protocol (PROSPERO-ID: CRD42020191940) was registered and searches were completed using Medline, Proquest, Embase, …
