Several investigations as well as prospective studies have shown a significant correlation between glucose metabolism and atherosclerosis in patients without diabetes, but differences in parameters of glucose metabolism among the various degrees of coronary disease in such patients have not been specifically evaluated. ⋯ For patients with NGT and different extents of atherosclerotic disease, postload glycemia and HbA1c level are not equally distributed but are significantly higher in those with more severe disease. This suggests that the glycemic milieu correlates with the cardiovascular risk according to a linear model.

Since 2000, the Centers for Medicare & Medicaid Services (CMS) has been collecting information on beneficiaries' experiences with health care for Medicare managed care (MMC) and traditional fee-for-service (FFS) Medicare. ⋯ Our data suggest that managed care was better at delivering preventive services, whereas traditional Medicare was better in other aspects of care related to access and beneficiary experiences. These relative strengths should be considered when policy decisions are made that affect the availability of choice or influence beneficiaries to choose one model of care over another.

Multicenter Study Comparative Study Clinical Trial
Computed tomographic colonography (virtual colonoscopy): a multicenter comparison with standard colonoscopy for detection of colorectal neoplasia.
Conventional colonoscopy is the best available method for detection of colorectal cancer; however, it is invasive and not without risk. Computed tomographic colonography (CTC), also known as virtual colonoscopy, has been reported to be reasonably accurate in the diagnosis of colorectal neoplasia in studies performed at expert centers. ⋯ Computed tomographic colonography by these methods is not yet ready for widespread clinical application. Techniques and training need to be improved.

Delirium as a predictor of mortality in mechanically ventilated patients in the intensive care unit.
In the intensive care unit (ICU), delirium is a common yet underdiagnosed form of organ dysfunction, and its contribution to patient outcomes is unclear. ⋯ Delirium was an independent predictor of higher 6-month mortality and longer hospital stay even after adjusting for relevant covariates including coma, sedatives, and analgesics in patients receiving mechanical ventilation.
