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

Predictors of hospital readmission after fractures: One-year follow-up study

OBJECTIVE: Identify the incidence and predictive factors for readmissions of elderly hospitalized with fractures.METHOD: Prospective cohort study on 376 elderly people from a trauma referral large hospital in central Brazil. Data were collected from medical records of elderly people with radiological diagnosis of fractures. Readmission that occurs up to one year after the first discharge… Continue reading Predictors of hospital readmission after fractures: One-year follow-up study

Cannabis use and risks of respiratory and all-cause morbidity and mortality: a population-based, data-linkage, cohort study

Introduction Although cannabis is frequently used worldwide, its impact on respiratory health is characterised by controversy. Objective To evaluate the association between cannabis use and respiratory-related emergency room (ER) visits and hospitalisations. Methods A retrospective, population-based, cohort study was carried out, linking health survey and health administrative data for residents of Ontario, Canada, aged 12–65… Continue reading Cannabis use and risks of respiratory and all-cause morbidity and mortality: a population-based, data-linkage, cohort study

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,… Continue reading Prenatal antibiotic exposure, asthma and the atopic march: A systematic review and meta-analysis

Trajectories of asthma symptom presenting as wheezing and their associations with family environmental factors among children in Australia: evidence from a national birth cohort study

Objectives Asthma is one of the greatest health burdens, yet contributors to asthma symptom trajectories are understudied in Australian children. We aimed to assess the trajectories of asthma symptom and their associations with several family environmental factors during the childhood period in Australia. Design Secondary analysis from a cross-sequential cohort study. Setting Nationwide representative data… Continue reading Trajectories of asthma symptom presenting as wheezing and their associations with family environmental factors among children in Australia: evidence from a national birth cohort study

Steroid-induced fibroblast growth factors drive an epithelial-mesenchymal inflammatory axis in severe asthma

AbstractAsthma and inflammatory airway diseases restrict airflow in the lung, compromising gas exchange and lung function. Inhaled corticosteroids (ICSs) can reduce inflammation, control symptoms, and improve lung function; however, a growing number of patients with severe asthma do not benefit from ICS. Using bronchial airway epithelial brushings from patients with severe asthma or primary human… Continue reading Steroid-induced fibroblast growth factors drive an epithelial-mesenchymal inflammatory axis in severe asthma

Clustering of COPD patients and their response to pulmonary rehabilitation

Background and objectivePulmonary rehabilitation (PR) is fundamental in the management of chronic obstructive pulmonary disease (COPD). COPD patients show a large clinical heterogeneity that may influence their response to PR. Identification of homogeneous clusters of patients who may or may not respond to PR is important to personalize patient care. This study aimed at identifying… Continue reading Clustering of COPD patients and their response to pulmonary rehabilitation

COVID-19 Vaccine in Patients with Exacerbation of Idiopathic Pulmonary Fibrosis

To the editorBetween the end of 2020 and the beginning of 2021, the first mRNA vaccines against COVID-19 received approval for emergency use by the World Health Organization (WHO). Patientsaffected by fibrotic interstitial lung disease (ILD) were granted priority access to vaccination,as these patients may develop severe complications after SARS-CoV-2 infection and carry ahigher risk… Continue reading COVID-19 Vaccine in Patients with Exacerbation of Idiopathic Pulmonary Fibrosis
