Neural basis and recovery of spatial attention deficits in spatial neglect.
The syndrome of spatial neglect is typically associated with focal injury to the temporoparietal or ventral frontal cortex. This syndrome shows spontaneous partial recovery, but the neural basis of both spatial neglect and its recovery is largely unknown. We show that spatial attention deficits in neglect (rightward bias and reorienting) after right frontal damage correlate with abnormal activation of structurally intact dorsal and ventral parietal regions that mediate related attentional operations in the normal brain. Furthermore, recovery of these attention deficits correlates with the restoration and rebalancing of activity within these regions. These results support a model of recovery based on the re-weighting of activity within a distributed neuronal architecture, and they show that behavioral deficits depend not only on structural changes at the locus of injury, but also on physiological changes in distant but functionally related brain areas.

A tele-ultrasound needs analysis in Queensland.
A tele-ultrasound survey was distributed to clinicians and sonographers in regional and rural sites throughout Queensland. In all, 28 centres were invited to complete a profile questionnaire, and 27 centres were invited to complete a case-log. Twenty-five of the 28 questionnaires were returned (89% response rate). Twenty-two of the 27 case-logs were returned (81% response rate). Obstetric ultrasound was the most frequently performed ultrasound examination, accounting for 846 (35%) of the 2,410 recorded during the two-week survey period. The respondents considered that 182 cases would have benefited from further consultation: 79% for diagnostic advice, 13% for patient management advice and 8% for advice on examination technique. Six hospitals appeared to have the greatest need for a tele-ultrasound service. There was a strong preference for the store-and-forward transmission of static images: 70% preferred this modality, in comparison with 19% who preferred realtime transmission and 11% who preferred store-and-forward transmission of video clips.

Ethnic inequalities in cancer survival in New Zealand: linkage study.
We explored the contribution of stage at diagnosis to ethnic disparities in cancer survival in New Zealand. We linked 115811 adult patients with invasive cancer registered on the cancer registry (1994 to 2002) to mortality data. Age-standardized, 5-year relative survival rates were lowest for Maori, intermediate for Pacific people (otherwise known as Pacific Islanders), and highest for non-Maori/non-Pacific people for many cancers. Stage at diagnosis accounted for only part of these differences. Possible factors responsible for ethnic inequalities might include access to specialized cancer services and the quality of care received.

The need for critical care nurse education at preregistration level.
In order to deliver a comprehensive and high quality intensive care service, all intensive care providers must be suitably educated and trained. Both the NHS and higher education establishments have been subjected to radical reviews and reforms in order that they meet the educational demands of a changing healthcare system which requires that critical care be delivered to all patients whenever they need it and whenever they are being nursed in the hospital. To be able to deliver critical care throughout the whole of a hospital is a huge challenge. In order to impact upon patient morbidity/mortality, all staff nurses will need to learn, develop and employ critical care skills. In this article, we will explore issues that surround critical care education for all nurses.
