Abstract

BACKGROUND: Postoperative fatigue and deterioration in functional capacity have been correlated to postoperative weight loss. This suggested that nutritional support to enhance the regain of weight might improve upon the convalescence. METHODS: Patients were allocated randomly at discharge to standard management or to dietary advice and protein-rich supplements for 4 months. The convalescence of 32 patients admitted electively for colorectal surgery and of 21 operated on for acute obstruction or severe peritonitis was studied. RESULTS: The intervention substantially increased protein intake, gain in body-weight and lean body mass, especially in the legs as shown by dual-energy X-ray absorptiometry. Changes in work capacity, hand grip and pinching strength, fatigue and quality of life were similar in patients in control and intervention groups and had returned to preoperative values 1-2 months after operation, although fatigue was increased at 2-3 months. CONCLUSIONS: This study did not support the hypothesis that changes in weight were important for the changes in function and fatigue in patients with small to moderate weight loss.

Two years of growth hormone therapy in young children with Prader-Willi syndrome: physical and neurodevelopmental benefits.

Infants with Prader-Willi syndrome (PWS) typically display failure to thrive and decreased muscle mass with excess body fat for age. Growth hormone (GH) therapy in children with PWS improves, but does not normalize, body composition and muscle strength and agility. The objective of this study was to determine the effects of earlier GH therapy on anthropometric measurements, body composition, and psychomotor development in affected PWS infants and toddlers. Twenty-five subjects, ages 4-37 months, were randomized to 2 years of GH therapy (1 mg/m(2)/day) or 1 year of observation without GH treatment and then placed on GH (1.5 mg/m(2).day) for 1 year only. Anthropometric measurements were obtained by standard methods: percent body fat, lean body mass, and total body bone mineral density by dual x-ray absorptiometry; motor constructs of mobility and stability by the Toddler Infant Motor Evaluation; and cognitive and language function by the Capute Scales of Infant Language and Cognitive Development. GH-treated PWS subjects demonstrated normalization of length/height standard deviation scores (SDS), faster head growth, increased lean body mass accrual, and decreased percent body fat (P < 0.005 for all parameters), as well as improved language (P = 0.05) and cognitive (P = 0.02) quotient Z-scores compared with similarly aged untreated PWS subjects after 1 year into the study. PWS subjects treated before their first birthday spoke their first words at a mean age of 14.4 +/- 2.8 months and walked independently at 23.3 +/- 4.8 months. GH therapy was well-tolerated; however, one PWS subject experienced scoliosis progression. As greater benefits were seen in our study with early treatment, prompt referral to a pediatric endocrinologist for consideration of GH therapy is recommended for PWS at an early age.

Effect of plant sterols and exercise training on cholesterol absorption and synthesis in previously sedentary hypercholesterolemic subjects.

Plant sterols combined with exercise beneficially alter lipid profiles in hypercholesterolemic adults. Although the mechanism by which plant sterols favorably modulate lipid levels is well established, no trial to date has examined the effect of exercise, alone or combined with plant sterols, on cholesterol kinetics. Thus, the current objective was to examine the effects of exercise, plant sterols, and the combination of exercise and plant sterols on cholesterol absorption and synthesis. In an 8-week, parallel-arm trial, 84 subjects were randomized to 1 of 4 interventions: plant sterols combined with exercise, plant sterols, exercise, or control. Diets were not controlled. Total cholesterol and triglyceride levels decreased (P<0.01) by 7.7% and 11.8%, respectively, whereas high-density lipoprotein (HDL) cholesterol levels increased (P<0.01) by 7.5% in the combination group. Mean posttreatment low-density lipoprotein (LDL) cholesterol levels decreased (P<0.01) by 0.30 mmol/L in the combination group. Cholesterol absorption was 16% lower (P<0.01) in the combination group and 18% lower (P<0.01) in the plant sterol group, when compared with control. Exercise had no effect on cholesterol absorption. Nonsignificant increases in cholesterol synthesis rates of 63% (0.084+/-0.014 pools/day), 59% (0.075+/-0.013 pools/day), and 57% (0.072+/-0.011 pools/day) were observed in the combination, exercise, and plant sterol groups, respectively, relative to the control group (0.031+/-0.019 pools/day). LDL cholesterol levels correlated with cholesterol absorption, as represented by the area under the deuterium enrichment curve (r=0.23, P=0.05), and with percent absorption relative to control (r=0.25, P=0.03). These findings suggest that exercise does not modulate lipid levels by altering to cholesterol absorption or synthesis, whereas plant sterols favorably alter levels of LDL cholesterol by suppressing intestinal absorption.
