We assessed quality of life (QOL) in patients on home enteral tube feeding (HETF). The data should contribute to ethically justified decision making. ⋯ . Measures of QOL research can be used in HETF patients. QOL is reduced in patients on HETF. Part of this effect is explained by malnutrition. HETF can prevent further weight loss and improve some aspects of QOL, thus allowing physicians to focus on patients.

Comparative Study
Body composition interpretation. Contributions of the fat-free mass index and the body fat mass index.
Low and high body mass index (BMI) values have been shown to increase health risks and mortality and result in variations in fat-free mass (FFM) and body fat mass (BF). Currently, there are no published ranges for a fat-free mass index (FFMI; kg/m(2)), a body fat mass index (BFMI; kg/m(2)), and percentage of body fat (%BF). The purpose of this population study was to determine predicted FFMI and BFMI values in subjects with low, normal, overweight, and obese BMI. ⋯ BMI alone cannot provide information about the respective contribution of FFM or fat mass to body weight. This study presents FFMI and BFMI values that correspond to low, normal, overweight, and obese BMIs. FFMI and BFMI provide information about body compartments, regardless of height.

Comparative Study
Inhibition of oxidative stress in blood platelets by different phenolics from Yucca schidigera Roezl. bark.
We investigated the comparative effects of resveratrol (trans-3,4',5-trihydroxystilbene), trans-3,3',5,5'tetrahydroxy-4'-methoxystilbene, and yuccaols A and C isolated from the bark of Yucca schidigera on oxidative stress in resting blood platelets and blood platelets activated by different agonists (thrombin or thrombin receptor activating peptide). ⋯ Resveratrol and other phenolic compounds from the bark of Yucca schidigera inhibiting free radical generation in blood platelets may be beneficial in protecting against cardiovascular diseases when hyperactivity of platelets is observed.

The purposes of this study were to study the effects of folate and vitamins B6 and B12 on plasma homocysteine concentration and to estimate the risks for coronary artery disease (CAD) according to quartiles of plasma homocysteine concentration. ⋯ Serum folate, but not vitamin B6 or B12, was a strong predictor of plasma homocysteine; while all subjects had adequate B-vitamin status. Folate should be considered as a routine supplementation for individuals who have risk factors for CAD, even for individuals with adequate folate status.

The non-invasive (13)C-octanoic acid breath test ((13)C-OABT) has recently been used to monitor gastric emptying. We evaluated (13)C-OABT as a method for assessing gastric emptying in relation to the amount of milk ingested in preterm neonates during their first days of life. ⋯ In the first hours of gastric feeding, neither the age of the neonate nor the amount of administered (13)C-primed breast milk had any effect on t(1/2)GE. The gastric emptying rate and the evacuation curve shape for individual neonates were similar and independent of milk amount.
