This pre-post study used a mixed-methods approach to examine the impact of a family-based weight management program among a low-income population. Smart Choices for Healthy Families was developed through an integrated research-practice partnership and piloted with 26 children and parents (50% boys; mean age = 10.5 years; 54% Black) who were referred by(More)
The effect of short-term (biochemical) and long-term (clinical) essential fatty acid (EFA) deficiency on mucosal adaptation was studied in a surgical model of short bowel syndrome. Rats fed an EFA-deficient diet for 4 wk had biochemical evidence of EFA deficiency (hepatic and red blood cell triene to tetraene ratios greater than 0.4). Resected animals (70%(More)
In a previous study we observed that neutrophils respond with a rapid rise in [Ca2+]i during adherence to cytokine-activated endothelial cells (EC), caused by EC membrane-associated platelet-activating factor (PAF). In the present study, we investigated whether this form of PAF was important in neutrophil adherence and migration across monolayers of rIL-1(More)
We have shown that dietary long-chain triglycerides and 16,16-dimethyl prostaglandin E2 enhance and aspirin impairs postresection mucosal adaptation in rats. The present studies examined the hypothesis that supplemental linoleic acid (LA) above the minimum requirement may enhance postresection mucosal adaptation through altered prostaglandin (PG) synthesis.(More)
OBJECTIVE Due to a proliferation of measures for different components of the home environment related to childhood obesity, the purpose of the present systematic review was to examine these tools and the degree to which they can validly and reliably assess the home environment. DESIGN Relevant manuscripts published between 1998 and 2010 were obtained(More)
Few comprehensive measures exist to assess contributors to childhood obesity within the home, specifically among low-income populations. The current study describes the modification and psychometric testing of the Comprehensive Home Environment Survey (CHES), an inclusive measure of the home food, physical activity, and media environment related to(More)
The effect of zinc deficiency on glucose tolerance was investigated using intragastric force feeding to obviate decreased food intake and altered eating patterns. Three groups of weanling male Sprague-Dawley rats were fed a purified zinc-deficient diet: zinc-deficient, ad libitum-fed animals (ZDA) were offered powdered zinc-deficient diet; zinc-replete,(More)
Aluminum toxicity is a documented cause of encephalopathy, anemia, and osteomalacia. Excretion is primarily renal; therefore, patients with renal insufficiency are at risk for aluminum accumulation and toxicity. This has been demonstrated in uremic children treated with aluminum-containing antacids. The purpose of this study was to determine whether plasma(More)
