Actigraphy correctly predicts sleep behavior in infants who are younger than six months, when compared with polysomnography.

Actigraphy has been widely used in adults and children. In infants, validation of actigraphy has typically used a comparison with behaviorally determined sleep state classification rather than polysomnography (PSG). This study validated actigraphy against PSG for determining sleep and waking states in infants who were younger than 6 mo.

Increasing the evidence base for selection for undergraduate medicine: four case studies investigating process and interim outcomes.

Introduction: Prior to 1997, the University of Adelaide, Australia selected medical students according to matriculation marks alone. After extensive consultation with relevant stakeholders and examination of empirical evidence, the selection process is now based on a national written examination of reasoning and interaction skills, a structured oral assessment and a threshold matriculation score. This paper presents a series of 4 case studies examining the process related to the procedure and early interim outcomes, with the aim of adding to the evidence base for methods of medical student selection.

Interaction between bed sharing and other sleep environments during the first six months of life.

This investigation was carried out to determine the relationship between bed sharing and other places of infant sleep in the first six months of life, and to identify patterns of change in the place of infant sleep for infants who do and do not routinely bed share in the first six months of life. The sleep--wake behaviour and place of infant sleep were recorded, at weekly intervals, for bed sharing (n=25) and non-bed sharing (n=68) infants between 2 and 24 weeks after birth. Bed sharing infants spent a significantly increased proportion of their total sleep time per 24 h in other sleep environments which favoured close parental proximity and significantly less time in solitary sleep.
