Several diverse disorders, including the prevalent dementias and encephalopathies, are now believed to arise from the same general disease mechanism. In each, there is abnormal unfolding and then aggregation of an underlying protein. The gradual accumulation of these aggregates and the acceleration of their formation by stress explain the characteristic late or episodic onset of the clinical disease. The understanding of these processes at the molecular level is opening prospects of more rational approaches to investigation and therapy.

The provision of intensive care is a perplexing issue for clinicians and the public. Concerns about the apparent lack of beds and the appropriateness of the patients admitted are tempered by the high cost of providing this service. As part of a study commissioned by the UK Department of Health, we tested the hypothesis that there is excess mortality among patients who are refused admission to intensive-care units. ⋯ Although this study is observational and case-mix adjustment is incomplete, we found a higher rate of attributable mortality in patients who were refused intensive care, particularly for emergency cases. We question whether the provision of more beds alone would be a solution and conclude that there is an urgent need for more appropriate admission and discharge criteria.
