Diagnostic value of nasal nitric oxide measured with non-velum closure techniques for children with primary ciliary dyskinesia.
Nasal nitric oxide (nNO) is a reliable non-invasive screening test for primary ciliary dyskinesia (PCD), but the recommended technique, exhalation against resistance (ER), requires cooperation limiting its use in young children. Our objectives were to determine whether easier non-velum closure techniques have the ability to discriminate PCD and longitudinal reproducibility. ⋯ Non-velum closure techniques are reproducible and valid to discriminate PCD; however, they generally yield lower values than ER.

Multicenter Study Comparative StudyRacial and ethnic disparities in post-operative mortality following congenital heart surgery.
This study assessed racial/ethnic disparities in post-operative mortality after surgery for congenital heart disease (CHD) and explored whether disparities persist after adjusting for access to care. ⋯ There are notable racial/ethnic disparities in post-operative mortality after CHD surgery that do not appear to be explained by differences in access to care.

Comparative StudyChanges in lung volume and ventilation during lung recruitment in high-frequency ventilated preterm infants with respiratory distress syndrome.
To assess global and regional changes in lung volume and ventilation during lung recruitment in preterm infants with respiratory distress syndrome. ⋯ Lung hysteresis is present in preterm infants with respiratory distress syndrome. Regional differences in lung volume changes and ventilation during high-frequency oscillatory ventilation with lung recruitment are relatively modest and do not follow a gravity-dependent distribution.

Comparative StudyPrevalence of cardiometabolic risk factor clustering and body mass index in adolescents.
To establish prevalence of cardiometabolic risk factor clustering within US adolescent body mass index (BMI) groups. ⋯ The prevalence of risk factor clustering increases across adolescent BMI categories; however, associations with sex, race/ethnicity, income, smoking, and BMI vary across groups.
