An examination of the needs of parents of hospitalized children: comparing parents' and staff's perceptions

The needs of parents of hospitalized children have received some attention in the health literature, but few studies have compared parents' perceptions of needs with staff's ideas about parents' needs. The aim of this Study was to examine differences between the perceptions of the needs of parents of hospitalized children held by staff - nurses, doctors and allied health staff, and parents in a 150-bed paediatric hospital in Sweden. The convenience sample comprised 132 staff - nurses, doctors and allied health stall and 115 parents of children admitted to all the wards except intensive care. Kristjansdottir's needs of parents of hospitalized children questionnaire (NPQ) was the instrument of choice and was modified slightly for use with staff. Results indicated significant differences in perceptions of the importance of different needs of parents, of how well they were being met in the hospital arid how much help the parents needed to have them filled. Differences between parents' and staff's perceptions of the importance of parental needs were found in areas relating to psychosocial needs, but in general, in that hospital, the needs were being adequately met. The main differences between staff's and parents' results were in the degree of independence shown by parents in requiring hell) to have their needs met. This demonstrates either that parents are much more independent than appraised by staff, or, that parents are sometimes unaware of the level of assistance available.

Modulating the rate and rhythmicity of perceptual rivalry alternations with the mixed 5-HT2A and 5-HT1A agonist psilocybin

Binocular rivalry occurs when different images are presented simultaneously to corresponding points within the left and right eyes. Under these conditions, the observer's perception will alternate between the two perceptual alternatives. Motivated by the reported link between the rate of perceptual alternations, symptoms of psychosis and an incidental observation that the rhythmicity of perceptual alternations during binocular rivalry was greatly increased 10 h after the consumption of LSD, this study aimed to investigate the pharmacology underlying binocular rivalry and to explore the connection between the timing of perceptual switching and psychosis. Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine, PY) was chosen for the study because, like LSD, it is known to act as an agonist at serotonin (5-HT)(1A) and 5-HT2A receptors and to produce an altered state sometimes marked by psychosis-like symptoms. A total of 12 healthy human volunteers were tested under placebo, low-dose ( 115 mg/kg) and high-dose ( 250 mg/kg) PY conditions. In line with predictions, under both low- and high-dose conditions, the results show that at 90 min postadministration ( the peak of drug action), rate and rhythmicity of perceptual alternations were significantly reduced from placebo levels. Following the 90 min testing period, the perceptual switch rate successively increased, with some individuals showing increases well beyond pretest levels at the final testing, 360 min postadministration. However, as some subjects had still not returned to pretest levels by this time, the mean phase duration at 360 min was not found to differ significantly from placebo. Reflecting the drug-induced changes in rivalry phase durations, subjects showed clear changes in psychological state as indexed by the 5D-ASC ( altered states of consciousness) rating scales. This study suggests the involvement of serotonergic pathways in binocular rivalry and supports the previously proposed role of a brainstem oscillator in perceptual rivalry alternations and symptoms of psychosis.
