Overview article: basal lamina of epidermis, muscle fibers, muscle capillaries, and renal tubules: changes with aging and in diabetes mellitus.

Using autopsy material from 14 diabetics and 10 controls (8-84 years old), the authors measured the thickness of basal lamina (BL) in skeletal muscle capillaries, renal tubules, skeletal muscle fibers, and epidermis to determine whether BL accumulation is a generalized phenomenon or limited only to certain anatomic structures. The four structures were selected because earlier experiments in animals have shown that in two (muscle capillaries and renal tubules) BL accumulates as a by-product of cell renewal while in the other two (muscle fibers and epidermis) it does not. In human tissues we found that BL accumulates in muscle capillaries and renal tubules but not in muscle fibers and epidermis, in muscle capillaries and in renal tubules it accumulates in controls and in diabetics as a function of aging, more BL in both anatomic structures accumulates in diabetics than in controls, and the extent of BL accumulation in muscle capillaries and renal tubules does not correlate with duration of diabetes mellitus. In addition to the fact that BL does not accumulate in all anatomic structures in which BL is normally present, the observations indicate that diabetes alone is not responsible for BL accumulation, diabetes exaggerates age-dependent accumulation of BL, and accumulation of BL in man is probably a by-product of cell renewal.

Characteristics of health promotion programs in Federal worksites: findings from the Federal Employee Worksite Project.

PURPOSE: To describe how well-established health promotion programs at selected federal worksites were designed, organized, and implemented and to identify factors related to employee participation. DESIGN: This descriptive study related characteristics of the health promotion program, worksites, and workforce to employee participation and perceptions of program impacts. SETTING: The study was conducted at 10 established federal worksite health promotion programs in various regions of the country. SUBJECTS: A total of 3403 of 5757 federal employees (59%) sampled completed employee surveys. MEASURES: Study data were collected from on-site observations, interviews, focus groups, and employee surveys. RESULTS: Overall, program participation rates were high, and employees reported positive impacts on their health and attitudes toward the agency. Participation in health screening, perceived program convenience, and perceived support by management and others were important determinants of participation and of perceived work-related outcomes. CONCLUSIONS: Although site selection and response rate limit generalizability, the sites evaluated represent a broad cross-section of different types and sizes of agencies. The findings should be relevant in many other settings. Study programs compare favorably with private sector programs. Employees viewed the programs very positively. The most cogent challenge in justifying these, and perhaps other, worksite programs is that most participants already or simultaneously engage in health promotion activities elsewhere "on their own."

Screening for depression in well older adults: evaluation of a short form of the CES-D (Center for Epidemiologic Studies Depression Scale).

We derived and tested a short form of the Center for Epidemiologic Studies Depression Scale (CES-D) for reliability and validity among a sample of well older adults in a large Health Maintenance Organization. The 10-item screening questionnaire, the CESD-10, showed good predictive accuracy when compared to the full-length 20-item version of the CES-D (kappa = .97, P < .001). Cutoff scores for depressive symptoms were > or = 16 for the full-length questionnaire and > or = 10 for the 10-item version. We discuss other potential cutoff values. The CESD-10 showed an expected positive correlation with poorer health status scores (r = .37) and a strong negative correlation with positive affect (r = -.63). Retest correlations for the CESD-10 were comparable to those in other studies (r = .71). We administered the CESD-10 again after 12 months, and scores were stable with strong correlation of r = .59.
