Randomized Controlled Trial
Short-term folinic acid supplementation improves vascular reactivity in HIV-infected individuals: a randomized trial.
HIV-infected individuals present a cluster of conditions that activate or injure the vascular endothelium. The administration of folates may exert beneficial effects on endothelial function in different populations at risk for cardiovascular disease. The aim of this study was to determine the effects of 4 wk of folinic acid supplementation on forearm vascular responses during reactive hyperemia in HIV-infected patients under highly active antiretroviral therapy. ⋯ Short-term folinic acid supplementation improved vascular reactivity in HIV-infected individuals enrolled in the studied. As folate supplementation is safe and relatively inexpensive, long-term clinical trials should be conducted.

Multicenter Study Comparative Study
Novel diet for patients with impaired mastication evaluated by consumption rate, nutrition intake, and questionnaire.
"iEat(®)" (EN Otsuka Pharmaceutical Co. Ltd.; study diet), a food product that resembles an ordinary meal in appearance but is cooked to soften, was compared with foods provided to patients with impaired mastication (modified traditional diet) to investigate the influence of the appearance of foods on the consumption rate, dietary nutrition intake, and satisfaction level. ⋯ The study diet has potential to become a new dietary option for patients with impaired mastication.

Randomized Controlled Trial
The effect of hyperhomocysteinemia on aortic distensibility in healthy individuals.
Elevated plasma homocysteine (HCY) levels have been associated with increased risk for cardiovascular disease. Aortic distensibility and aortic pulse wave velocity (PWV) are indices of aortic elasticity. The potential effect of acute hyperhomocysteinemia (HHCY) on the elastic properties of the aorta in healthy individuals is not known. The aim of the present study was to determine the effect of acute methionine-induced HHCY on aortic distensibility and PWV in healthy individualsand the effect of acute HHCY on myocardial performance of the left ventricle (Tei index). ⋯ Acute methionine-induced HHCY reduces aortic distensibility and worsens myocardial performance in healthy individuals. Further research is warranted to examine in the long term the direct effects of HHCY on cardiovascular function and the indirect effects on structural remodeling.

Randomized Controlled Trial
Glycemic response to carbohydrate and the effects of exercise and protein.
The purpose of this study was to investigate the effects of pre-exercise and protein coingestion on the glycemic response to carbohydrates. ⋯ Coingestion of protein with carbohydrate reduces glycemic response and increases insulinemic response in healthy subjects, whereas pre-exercise seems to have no effect.
