CLINICAL UPDATE – Vitamin K deficiency may accelerate diseases of aging
Current recommendations for vitamin K are not being met, placing people at increased risk of age-related diseases such as cancer and heart disease, says a new analysis

CLINICAL UPDATE – ApoB and non-HDL cholesterol not clinical equivalents
Although there is a high correlation between apoB and non-HDL cholesterol, this paper presents a series of examples where apoB and non-HDL cholesterol differ dramatically, thus altering the clinical diagnosis significantly.

CLINICAL UPDATE – Correcting deficiencies in vitamins B, C and D improves endothelial function
Researchers found that dilation of blood vessels improved dramatically in 23 asymptomatic but vitamin D deficient people who were supplemented with vitamin D for 3 months. A randomized clinical trial of B vitamins and garlic extract on 65 intermediate risk patients supplemented for one year significantly reduced the progression of atherosclerosis. Similarly, a recent review on vitamin C discusses how it can help induce vasodilation.

CLINICAL UPDATE – Low choline status associated with high anxiety
Over 5900 patients were studied and researchers found that low choline levels were significantly associated with anxiety symptoms.

CLINICAL UPDATE – Vitamin B12 deficiency common in diabetics
In a study of 203 type II diabetics, researchers confirmed a vitamin B12 deficiency in 22% of patients, and those taking metformin had even lower levels of vitamin B12. In a similar study in India, vitamin B12 deficiency during pregnancy was associated with obesity, insulin resistance and gestational diabetes.

CLINICAL UPDATE – Antioxidant supplementation reduced healing time in pediatric burns
A randomized controlled trial of 32 children with burn injuries showed that supplementation with vitamin C, E and zinc reduced their wound healing time and markers of oxidative stress while in the hospital.
