Clinical staff and the new student nurse: anticipating change.

This article focuses on the feelings and perceptions of clinical staff who are about to encounter Project 2000 students. It makes use of selected findings from a small exploratory study in which interviews were used to gather qualitative data from such staff. There is a brief consideration of the historical context of nurse education from which Project 2000 has arisen and the legislation that has been instrumental in its development. Embodied within this change is the expectation that clinical staff will continue to contribute to the education of student nurses on clinical placements. The target population for this study was identified as clinical staff who would be working with Project 2000 students within a large general teaching hospital. Through means of taped informal interviews, the study explored the world of the clinical staff in relation to their expectations of Project 2000 students. It identified feelings of threat, lack of communication and issues of change and its implementation. For successful implementation and wide acceptance of such a radical change in nurse education, consistency of knowledge and communication was shown to be essential.

A microelectronic conductimetric biosensor.

The fabrication and operation of a microelectronic conductimetric biosensor is described. The device monitors the change in solution conductance occasioned by the catalytic action of enzymes immobilised over a planar conductance cell comprising serpentined and interdigitated metal conductor tracks. The output of the instrument was linear over a 3 min period on addition of urea to a sample cell overlaid with immobilised urease. The responses to any given urea concentration were reproducible to within approximately +/- 1%. The device responds to urea present in serum samples.

Developments in surgical oncology--past, present, and future trends.

The historical development of integrated treatment programs for locally advanced or aggressive cancers, for which the results of surgical excision or radiotherapy are unsatisfactory, is reviewed. Chemotherapy should be used first (induction chemotherapy), while tumour vasculature is intact; intra-arterial infusion gives a greater regional effect. Central residual tumour may be eradicated by subsequent radiotherapy and/or surgery. Regional induction chemotherapy is particularly useful in treating locally advanced stage III breast cancer, locally advanced head and neck cancer, gastric cancer, and locally advanced sarcomas and melanomas of the limbs. A team approach, involving surgical and medical oncologists, radiotherapists, immunologists, and others should improve the results in these patients.
