Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators will examine the possible synergistic effects of obstructive sleep apnea (OSA) and type II diabetes mellitus (DM) on vascular functioning by performing a two-part investigation:

* A cross-sectional study comparing subjects with OSA+DM, OSA only, DM only, and healthy controls.
* A three-month randomized placebo-controlled trial of continuous positive airway pressure (CPAP) in subjects with OSA+DM.
