Objective: Respiratory motion can affect image quality and thus affect the diagnostic accuracy of CT images by masking or mimicking relevant lung pathologies. CT examinations are often performed during deep inspiration and breath-hold to achieve optimal image quality. However, this can be challenging for certain patient groups, such as children, the elderly, or sedated patients.

While research on auditory attention in complex acoustical environment is a thriving field, experimental studies thus far have typically treated participants as passive listeners. The present study-which combined real-time covert loudness manipulations and online probe detection-investigates for the first time to our knowledge, the effects of acoustic salience on auditory attention during live interactions, using musical improvisation as an experimental paradigm. We found that musicians were more likely to pay attention to a given co-performer when this performer was made sounding louder or softer; that such salient effect was not owing to the local variations introduced by our manipulations but rather likely to be driven by the more long-term context; and that improvisers tended to be more strongly and more stably coupled when a musician was made more salient.

Unlabelled: The purpose of this study was to translate and validate a questionnaire to be used by children with chronic diseases during procedures. Specific research questions were as follows: Is the translated versions reliable? Is there a correlation between VCM and another questionnaire measuring discomfort to enhance the validity of VCM? The three versions of Visual CARE measure (VCM) were translated following the principles of good practice for translation and cultural adaptation of patient-reported outcome measures, according to the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Cognitive debriefing interviews with children, parents, and healthcare professionals were carried out.

Background: Posttraumatic headache is common in pediatrics. Studies have examined treatment of postconcussion symptoms, but few target posttraumatic headache. Biofeedback therapy has been studied in children and teens with primary headaches, but not posttraumatic headache.

Background: Pediatric respiratory syncytial virus (RSV)-related acute lower respiratory tract infection (LRTI) commonly requires hospitalization. The Clinical Progression Scale Pediatrics (CPS-Ped) measures level of respiratory support and degree of hypoxia across a range of disease severity, but it has not been applied in infants hospitalized with severe RSV-LRTI.

Methods: We analyzed data from a prospective surveillance registry of infants hospitalized for RSV-related complications across 39 U.
