Active and Passive Smoking and the Incidence of Asthma in the Black Women's Health Study.
Evidence linking active or passive smoking to the incidence of adult-onset asthma is inconsistent with both positive and inverse associations being reported. Most previous studies of active smoking have not accounted for passive smoke exposure, which may have introduced bias. ⋯ In this large population with 16 years of follow-up, active smoking increased the incidence of adult-onset asthma, and passive smoke exposure increased the risk among nonsmokers. Continued efforts to reduce exposure to tobacco smoke may have a beneficial effect on the incidence of adult-onset asthma.

Clinical TrialExhaled Biomarkers and Gene Expression at Preschool Age Improve Asthma Prediction at Age Six.
A reliable asthma diagnosis is difficult in wheezing preschool children. ⋯ Adding information on exhaled VOCs and possibly expression of inflammation genes to the API significantly improves an accurate asthma diagnosis in preschool children. Clinical trial registered with www.clinicaltrial.gov (NCT 00422747).

Inflammation, Metabolic Dysregulation and Pulmonary Function Among Obese Asthmatic Urban Adolescents.
Insulin resistance and low high-density lipoprotein (HDL) are associated with pulmonary morbidity, including asthma, but the underlying mechanisms are not well elucidated. ⋯ Th1 polarization and monocyte activation among obese subjects with asthma correlates with metabolic abnormalities. Association of monocyte activation with pulmonary function is mediated by body mass index, whereas that of Th1 polarization is mediated by insulin resistance.

Treatment is needed for obstructive sleep apnea (OSA) because untreated OSA can result in serious health problems. Continuous positive airway pressure (CPAP) therapy is the most common treatment used for obstructive sleep apnea (OSA). (see ATS Patient Series http://patients.thoracic.org/wp-content/uploads/ 2014/03/obstructive-sleep-apnea.pdf) For those who cannot use CPAP or want to try another option, there are other therapies that can work for people with OSA.

Diabetes-Related Mortality in Adults with Cystic Fibrosis: Role of Genotype and Gender.
Diabetes is associated with increased mortality in cystic fibrosis. Aggressive screening and early institution of insulin treatment significantly reduced this risk over the period of 1992-2008. ⋯ Despite substantial improvement over time, mortality for CFRD patients greater than 30 years remains higher than for patients with CF without diabetes.
