Infant Gut Bacteria May Reveal Asthma and Allergy Risk
Previous studies have shown that “the gut microbiota differs in composition and diversity during the first months of life in children who later do or do not have allergic disease," but researchers who focused on immunoglobulin A prevalence made a different finding.
People most at risk of needing adrenaline auto-injectors tend not to know how to use them properly, studies have found. Physicians are blamed for the lapses.
The pros identified included the possibility of EMDs improving adherence, that the devices might help motivate patients through creating a sense of independence and accountability, and that the data generated could help in building a trusting relationship between clinician and patient.
Smoking teens, rogue genes, and mashed-up hookworms are among the many diverse, fascinating, and important asthma topics that came out of 2016.

Only 5-10% of asthma sufferers have "severe" asthma, but account for about 50% of the social cost of the disease. The current focus in research is on finding therapies to treat specific components of the inflammation.
A new article in the Journal of Allergy and Clinical Immunology argues that genetic studies of asthma, expected to be game-changers, have “delivered neither meaningful clinical diagnostic tools nor useful insights into disease pathogenesis.”
A study out of the University of Pittsburgh identifies significant comorbidity and negative outcomes in those with insomnia and asthma, and finds that even asthmatics who report no nighttime breathing disturbances still face a predisposition to sleeplessness.
Individuals with atopic asthma were recently found to have a distinctive bronchial bacterial microbiome that not only differs from those without asthma, but between asthmatics with phenotypes more responsive or resistant to inhaled corticosteroids.
