Effectiveness of a clinical practice guideline for parenteral nutrition: a 5-year follow-up study in a pediatric teaching hospital.

Objective: To determine the effectiveness of a clinical practice guideline (CPG) on the use of parenteral nutrition (PN) at a tertiary care pediatric hospital.

Methods: Review of prospectively collected data on hospital-wide PN use 2 years before and 5 years after the establishment of the CPG. Effectiveness of the CPG was measured as the percentage of PN courses lasting fewer than 5 days and the number of PN starts per 1000 patient days.

Measurement of body fat by dual-energy X-ray absorptiometry and bioimpedance analysis in men with prostate cancer.

Objective: The aims of this study were to determine the percentage of body fat (%BF) by dual-energy x-ray absorptiometry (DXA) and bioelectrical impedance analysis (BIA) using a standard adult equation and BIA using a standard geriatric equation in a population of older men with prostate cancer and to compare the results from these different methods.

Methods: We conducted a cross-sectional study in 38 men with locally advanced, node-positive, or recurrent prostate cancer and no history of androgen-deprivation therapy. Body composition was evaluated by DXA with the use of a Hologic 4500A densitometer and BIA.
