Treatment with lovastatin plus diet slows the rate of progression and increases the frequency of regression in coronary artery lesions (by global change score), especially in more severe lesions (by quantitative angiography). This is the third lipid-lowering trial to show a benefit using the global change score, an end point predictive of clinical coronary events. Differences between two of these trials, using quantitative coronary angiographic end points, may have theoretical bearing on the mechanisms by which lipid-lowering therapy operates at the level of the arterial wall.

An intensive, progressive exercise program combined with education reduces disability and improves function in patients who have undergone a single-level lumbar microdiskectomy.

The purpose of this study was to document predictors of long-term retention among minority participants in the Well Elderly 2 Study, a randomized controlled trial of a lifestyle intervention for community-dwelling older adults. The primary sample included 149 African American and 92 Hispanic men and women aged 60–95 years, recruited at senior activity centers and senior residences. Chi-square and logistic regression procedures were undertaken to examine study-based, psychosocial, and health-related predictors of retention at 18 months following study entry. For both African Americans and Hispanics, intervention adherence was the strongest predictor. Retention was also related to high active coping and average (vs. high or low) levels of activity participation among African Americans and high social network strength among Hispanics. The results suggest that improved knowledge of the predictors of retention among minority elders can spawn new retention strategies that can be applied at individual, subgroup, and sample-wide levels.

An intensive, progressive exercise program combined with education increases quality of life in patients who have recently undergone lumbar microdiskectomy.
