Assessing Asthma Exacerbation Susceptibility Previous research indicates that 50% of patients with asthma report having had an exacerbation in the previous year despite the majority of these individuals reporting that they have “mild” disease. Few studies have assessed the characteristics and determinants of exacerbations. For a study, researchers assessed exacerbations and their associations among African Americans with asthma. Asthma control was assessed using the 5-item Asthma Control Questionnaire (ACQ5). The likelihood of a future exacerbation increased with worsening ACQ5 scores. The investigators identified an exacerbation susceptibility phenotype that was independent of asthma control and may require more precise therapeutic targeting. ————————————————————– Milk Allergy & QOL Current data are lacking on quality of life (QOL) measures among patients with an allergy to cow’s milk. Patients who are allergic to cow’s milk (or their guardians) and were candidates for oral food challenge or desensitization completed a QOL questionnaire over a 3-year period for a study. Among respondents, 45% reported in the fields of “emotional impact” and “symptoms of disease” that food allergies affected their life in moderation. About 52% reported that they were affected somewhat by the negative repercussions of their allergy. Nearly half (49%) of participants reported that the impact of social and dietary restrictions was serious. Also, 55% said they were slightly affected by personal expectations regarding their disease and its repercussions. Additionally, 72% had only discrete future expectations regarding improvement of their disease. ————————————————————– Selecting Patients for Thermoplasty Brochial thermoplasty (BT) is an endoscopic treatment for severe persistent asthma in which heat is applied to the small airway for 10 seconds, causing atrophy of the small...

New research was presented at ACAAI 2016, the annual scientific meeting of the American College of Allergy, Asthma & Immunology, from November 10 to 14 in San Francisco. The features below highlight some of the studies presented at the conference. Smoking Among Asthmatic Teens Previous research has shown that smoking rates among teens with asthma are relatively high. However, data are lacking on how smoking and smoking dependence differ between teens with asthma and those without the condition. For a study, researchers surveyed adolescents aged 13 to 19 about their smoking habits. When compared with participants who did not have asthma, teens with asthma were more likely to smoke, have some degree of nicotine dependence, and have tobacco dependence. Curiosity about cigarette smoking was identified as the primary reason why teens with asthma started smoking. ————————————————————– Asthma Risk & Access to Fresh Foods Recent studies have linked obesity with a higher incidence of asthma and worse outcomes. A lack of access to healthy foods has been established as a driver of obesity, but few studies have assessed the impact of this phenomenon on asthma. Study investigators compared the prevalence of pediatric asthma between children with and without access to fruits, vegetables, and other fresh foods for a study. Among children without access, 21% had asthma, compared with a rate of 17% observed among those with access. Children in the study who lived more than 1 mile from a grocery store had 53% greater odds of having asthma. ————————————————————– The Effect of Introducing Allergenic Foods Early Evidence suggests that the timing of introducing allergenic foods into an...
