The stenosis was treated with balloon dilation, and a second covered stent was placed rostral to and overlapping the first stent, spanning the stenotic region. Eleven months after this procedure, the dog was doing well. Results for this patient suggested that ventral rhinotomy and covered nasopharyngeal stent placement can be used successfully for the management of osseous choanal atresia in dogs; however, careful attention to preoperative planning and potential complications is necessary.

Breathing exercise interventions, however, tend not to be studied in isolation. The aim of the study was to examine the impact of a breathing exercise using a web-based app on the stress levels of direct care workers (DCWs) who serve people with intellectual and developmental disabilities. Design Uncontrolled one-group intervention. Settings/Location DCWs were recruited from intellectual and developmental disability service providers in a US Midwestern state. Subjects Sixty-four DCWs who used the breathing exercise app at least 2 times. Interventions Breathing exercise using a web-based app for a month. Outcome measures Five measures were obtained from the data recorded in the app initial stress level before exercise, exercise duration in minutes, change in stress level between before and after each breathing exercise, and frequency and number of days the app was used during a month
