Sleep reactivity mediates the relationship between sensory-processing sensitivity and insomnia symptoms severity: A cross-sectional correlational study.

Sensory-processing sensitivity (SPS) is a temperamental trait that describes individual differences in sensitivity to environmental stimuli. Previous studies have shown that highly sensitive individuals are more vulnerable to stress and to sleep-related difficulties. In light of this evidence, we hypothesized that SPS is associated with an increase in insomnia symptoms and that this correlation would be mediated by increased perceived stress and sleep reactivity.

Kitten Scanner reduces the use of sedation in pediatric MRI.

The use of sedation before a magnetic resonance imaging (MRI) scan is a common practice to overcome motion artifacts and anxiety in children. However, this technique has its drawbacks. We retrospectively compared the number of children undergoing a brain MRI scan with or without sedation before and after the introduction of an educational training protocol using a toy scanner (the Philips Kitten Scanner) and we investigated the effectiveness of this training in relation to children's age and gender.
