Systematic review using GRADE of the impact of exposure to volatile organic compounds (VOCs), cleaning agents, mould/damp, pesticides on the risk of (i) new-onset asthma (incidence) and (ii) adverse asthma-related outcomes (impact). MEDLINE, EMBASE and Web of Science were searched for indoor pollutant exposure studies reporting on new-onset asthma and critical and important asthma-related outcomes. Ninety four studies were included: 11 for VOCs (7 for incidenceand 4 for impact), 25 for cleaning agents (7 for incidenceand 8 for impact), 48 for damp/mould (26 for incidence and 22 for impact) and 10 for pesticides (8 for incidence and 2 for impact). Exposure to damp/mould increases the risk of new-onset wheeze (moderate certainty evidence). Exposure to cleaning agents may be associated with a higher risk of new-onset asthma and with asthma severity (low level of certainty). Exposure to pesticides and VOCs may increase the risk of new-onset asthma (very low certainty evidence). The impact on asthma-related outcomes of all major indoor pollutants is uncertain. As the level of certainty is low or very low for most of the available evidence on the impact of indoor pollutants on asthma-related outcomes more rigorous research in the field is warranted.

Studying the association between mixtures of environmental exposures and health outcomes can be challenging due to issues such as correlation among the exposures and non-linearities or interactions in the exposure-response function. For this reason, one common strategy is to fit flexible nonparametric models to capture the true exposure-response surface. However, once such a model is fit, further decisions are required when it comes to summarizing the marginal and joint effects of the mixture on the outcome.

Objectives: Despite growing interest in environmental and social determinants of health, few studies have explored how residential mobility influences respiratory health outcomes. We examined the relationship between levels of opportunity across education, health and environment, social and economic, and all domains in a child's neighborhood and the likelihood of emergency department (ED) visits for asthma and showed how moving from one neighborhood to another would affect the odds of visiting the ED for asthma.
Methods: In this cross-sectional study, we analyzed asthma-related ED visits among children aged 2 to 17 years in 9 US states (Arizona, Florida, Kentucky, Maryland, New Jersey, North Carolina, Oregon, Rhode Island, and Wisconsin) during 2016-2019.

Purpose: Omalizumab improves clinical outcomes for patients with severe asthma (SA), but its long-term effectiveness and potential biomarkers for predicting patient response require further investigation. This study aimed to evaluate the real-world effectiveness of omalizumab in treating SA and to identify potential biomarkers for predicting a favorable treatment response.
Materials And Methods: Clinical outcomes were compared between asthma patients receiving omalizumab (omalizumab group) and those on inhaled corticosteroid with long-acting beta-agonist (ICS-LABA) alone (ICS-LABA group).

Background: The hemoglobin-to-red cell distribution width ratio (HRR) is a newly identified inflammatory biomarker associated with various inflammatory diseases. Asthma is a major global health burden and an inflammatory airway disease significantly affected by inflammation. This study primarily aims to evaluate the relationship between HRR and asthma, as well as asthma-related outcomes, including stable asthma and asthma exacerbations in the past year.

Background: Awareness of factors associated with life-threatening asthma attacks and asthma mortality is essential for risk prediction in asthma care. There is limited evidence to inform risk factors in children and young people (CYP). The aim of this systematic review is to synthesize existing data to report risk factors for life-threatening asthma attacks and asthma deaths in CYP.
