Effects of work permits on illegal employment among youth workers: findings of a school-based survey on child labor violations.

We compared self-reported child labor violations between teenagers with and without work permits. Data were obtained from a school-based survey of working teenagers in 16 randomly selected high schools in North Carolina. We examined associations between work hour violations, hazardous order violations (performance of illegal tasks), and possession of a work permit.

Oscillations in cardiovascular function during acute hypoxia in the newborn piglet are associated with less neurological damage and occur more frequently in females.

The function of the cardiovascular system during hypoxia is an important determinant of neurologic outcome. Oscillations in blood pressure, particularly type-3 waves with a duration of 10 to 160 s, have been shown to occur in the presence of hypoxia in the neonatal rat. The aim of this study was to determine the characteristics and occurrence of type-3 waves in the neonatal piglet and any relationship to neurologic damage after acute global hypoxia.

Associations between serum cortisol, cardiovascular function and neurological outcome following acute global hypoxia in the newborn piglet.

Perinatal asphyxia is a significant contributor to neonatal brain injury. However, there is significant variability in neurological outcome in neonates after global hypoxia-ischemia. The aims of this study were to identify which physiological response/s during global hypoxia-ischemia influence the severity of brain injury and to assess their relative importance.
