TL;DR: Vitamin D supplementation is ineffective as an agent for lowering BP and thus should not be used as an antihypertensive agent.

TL;DR: Early changes in microvascular function are present in young patients with type 1 diabetes, long before the initial clinical presentation, and may be related to complex interactions between structural abnormalities and functional changes in the endothelium, smooth muscle, and nitric oxide activity.

TL;DR: It is clear from previous studies that laser Doppler flowmetry/imaging provides an easy, validated, and reproducible method for investigators to assess and monitor endothelial function in patients with a variety of pathologic conditions, but a standardization of protocols would help reduce the apparent controversy seen in the literature.

TL;DR: The idea that peripheral measurements of skin blood flow are representative of generalized microvascular function including that of the coronary circulation in normal healthy subjects is supported.

TL;DR: TC smokers, particularly females, demonstrate significant improvement in vascular health within 1 month of switching from TC to EC, and may be considered a harms reduction measure.
