Randomized Controlled Trial Multicenter Study Clinical Trial
Prevention of functional impairment by endarterectomy for symptomatic high-grade carotid stenosis. North American Symptomatic Carotid Endarterectomy Trial Collaborators.
To determine whether carotid endarterectomy prevents deterioration of functional status among patients with transient ischemic attacks or nondisabling strokes and ipsilateral carotid stenosis of 70% to 99%. ⋯ Carotid endarterectomy reduced the risk for impairment of function among patients with recent symptomatic cerebral ischemia and ipsilateral high-grade carotid stenosis.

The demand for medical services such as critical care is likely to often exceed supply. In the setting of these constraining conditions, institutions and individual providers of critical care must use some moral framework for distributing the available resources efficiently and equitably. ⋯ Patients who are not expected to benefit from intensive care, such as those with imminently fatal illnesses or permanent unconsciousness, should not be placed in the intensive care unit. Hospitals should assign individuals the responsibility of intensive care triage, and a committee should oversee the performance of this responsibility to facilitate the most efficient and equitable use of intensive care.

To assess risk factors for high-grade cervical dysplasia among southwestern Hispanic and non-Hispanic white women. ⋯ The strongest risk factor associated with high-grade cervical dysplasia among clinic attendees was HPV infection. Although most of the risk factors we examined showed similar associations for dysplasia for both ethnic groups, our data suggest that several different risk factors may be relevant to the development of cervical dysplasia in Hispanics compared with non-Hispanic whites who attend the same clinics.
