Abstract: Sera from 101 patients with progressive systemic scleroderma were analyzed for circulating aminopropeptides of type III collagen using a radioimmunoassay which measures the intact and degraded forms (Fab assay). About 41% of the patients were found to have values above the normal range. A good correlation was observed between elevated levels of aminopropeptides and the degree of involvement of the skin and internal organs in the patients. Most patients (89%) with an active progression of the disease but not those in a stationary phase showed increased serum levels of aminopropeptides. Treatment with corticosteroids apparently normalized the levels of aminopropeptides. Only minor changes were observed with an antibody-based radioimmunoassay which measures primarily the intact form of the aminopropeptide.

Abstract: Systematic multidimensional assessment techniques such as the Functional Assessment Inventory (FAI) are increasingly used with the elderly for outcome measurement, prediction of service needs, and accurate description for comparative purposes. The FAI is a structured interview followed by a rating process which compares patient status against standard descriptive phrases. Patients are assessed in five areas: mental health, physical health, social resources, economic resources, and activities of daily living (ADL). The validity of the FAI was tested by comparing ratings of patient health obtained by a single investigator using only the instrument with ratings obtained by consensus from an interdisciplinary home care team providing long-term care for the patients studied. An excellent level of agreement (weighted kappas from .583 to .780) was found in all areas studied. A single significant difference in ADL rating with a high correlation coefficient (r = .85) was interpreted as due to a difference between the single rater and the team in the definition of ADL. The ease of obtaining summary ratings from clinical personnel suggests that further exploration of this rapid quantification of patient health is warranted.

Abstract: This statement for physicians replaces the American Heart Association's Diet and Coronary Heart Disease, published in 1978. The current guidelines propose an optimal preventive diet for coronary heart disease. Emphasis is placed on the reduction of both saturated fat and total fat. Complex carbohydrates are recommended as the major replacement for calories from fat. Polyunsaturated and monounsaturated fats partially replace calories from other fat sources. Cholesterol and sodium guidelines are expressed relative to caloric intake, with an upper limit on each. The use of alcohol as a possible means of preventing cardiovascular disease is not advised. Maintenance of ideal body weight by calorie control and an adequate level of activity is emphasized.
