Randomized Controlled Trial Clinical Trial
Lipid effects of a dietary supplement softgel capsule containing plant sterols/stanols in primary hypercholesterolemia.
This randomized, placebo-controlled, crossover trial assessed the lipid-altering efficacy of a softgel capsule dietary supplement, providing esterified plant sterols/stanols 1.8 g/d, in 28 participants (≈ 75% women) with primary hypercholesterolemia (fasting low-density lipoprotein cholesterol [LDL-C] levels ≥ 130 and <220 mg/dL), a mean age of 58.4 y, and a mean body mass index of 27.9 kg/m(2). ⋯ The incorporation of softgel capsules providing esterified plant sterols/stanols 1.8 g/d into the NCEP TLC diet produced favorable changes in atherogenic lipoprotein cholesterol levels in these subjects with hypercholesterolemia.

Randomized Controlled Trial
Oral resveratrol and calcium fructoborate supplementation in subjects with stable angina pectoris: effects on lipid profiles, inflammation markers, and quality of life.
This study aimed to evaluate the effects of short-term (60-d) oral supplementation with calcium fructoborate, resveratrol, and their combination on the clinical and biological statuses of subjects with stable angina pectoris. ⋯ The results indicate that the combination of resveratrol and calcium fructoborate has beneficial effects in patients with angina

Diabetic macular edema and retinopathy are low-grade inflammatory conditions. Infusions of antitumor necrosis factor-α (anti-TNF-α) antibody and antivascular endothelial growth factor (anti-VEGF) antibody have been shown to be at least partly effective in the treatment of diabetic macular edema and proliferative diabetic retinopathy. Intravitreal therapy of diabetic macular edema by the anti-TNF-α antibody has been found to produce significant side effects and anti-VEGF therapy to be ineffective. ⋯ The retina is rich in polyunsaturated fatty acids, especially in ω-3, and several studies have shown that polyunsaturated fatty acids prevent diabetic retinopathy. Lipoxins, resolvins, and protectins derived from various polyunsaturated fatty acids possess anti-inflammatory actions and suppress the production of interleukin-6, and TNF-α and VEGF have antiangiogenic actions. In view of these evidences, I propose that lipoxins, resolvins, and protectins could be of significant benefit in the prevention and management of diabetic macular edema and retinopathy.

Randomized Controlled Trial
Evaluation of lipid peroxidation and antioxidant system in healthy iron-replete infants receiving iron prophylaxis.
Iron supplementation is commonly recommended for infants; however, there are some reports that it causes oxidative damage. The aim of this study was to investigate the potential effects of iron supplementation at 4 mo of age, for a period of 2 mo, on lipid peroxidation and free radical scavenging enzymes. ⋯ Our study indicates that the supplemental use of elemental iron 10 mg/d for a period of 2 mo in healthy iron-replete infants did not cause lipid peroxidation or an impairment of antioxidant status.

Comparative Study
Comparison of eicosapentaenoic acid concentrations in plasma between patients with ischemic stroke and control subjects.
ω-3 fatty acids, including eicosapentaenoic acid (EPA), prevent ischemic stroke. However, the clinical importance of EPA for ischemic stroke and its subtype has not been fully elucidated. ⋯ In this study, the plasma EPA concentration and the EPA/AA ratio were potential predictive risk factors for ischemic stroke, especially for cardioembolism. Further prospective studies are necessary.
