NCT03136263
This is a randomized, double-blind, placebo-controlled crossover study of single-dose intranasal oxytocin (24 IU) in 18-55 year-old men with attention deficit/hyperactivity disorder (ADHD). Following a screening visit to determine eligibility, participants will return for two main study visits. During the main study visits, study participants will receive either oxytocin (Syntocinon® nasal spray, Victoria Pharmacy, Zürich, Switzerland) or placebo (inactive ingredients of Syntocinon® nasal spray, Victoria Pharmacy), followed by assessments of cognitive control over attention and behavior. Twenty-four participants will be randomized 1:1 to one of two drug orders, i.e., oxytocin - placebo or placebo - oxytocin. In an additional neuroimaging substudy, a subset of participants will undergo task-based and resting-state functional magnetic resonance imaging (fMRI) following oxytocin/placebo administration to investigate the effects of oxytocin on fMRI activation and functional connectivity within the cognitive control network.

The goal of this interventional study is to compare at-home mobile spirometry to in-clinic spirometry in participants with moderate asthma while taking a long-acting beta agonist (LABA). The main questions it aims to answer are: * Do at-home mobile spirometry and in-clinic spirometry assessments show a similar treatment effect (measured changes in FEV1) with the addition of LABA? * Is at-home mobile spirometry as accurate as in-clinic spirometry in showing treatment effects (changes in FEV1)? Participants will be asked to: * Take standard of care LABA treatment once or twice a day * Complete at-home mobile spirometry testing twice a day * Complete asthma questionnaires twice a day * Complete device use questionnaires * Wear a wrist device (like a watch) to track physical activity and vital signs * Visit the clinic for in-clinic spirometry testing once a week for 8 weeks
