Improving Sleep, Sleep-related Outcomes, and Biomarkers in Veterans
NCT03968874
Recruiting
The primary purpose of this project is to determine the effect of morning bright light therapy (MBLT) on sleep in Veterans with traumatic brain injury (TBI). Secondarily, the project aims to identify blood-based brain biomarkers (BBBM) associated with sleep in Veterans. Specific Aim 1. Determine the effect of MBLT on sleep quality in Veterans (primary outcome). Specific Aim 2. Determine the effect of MBLT on downstream effectors of improved sleep, including cognition, mood, and quality of life... Read More

Pilot Study of BCAA on Sleep
NCT03990909
Recruiting
Individuals will be recruited from the VA Portland Health Care System and the community affiliated with Oregon Health \& Science University. Traumatic brain injury status will be assessed as a contributing factor. Subjects will be randomized to one of 3 groups (BCAA or one of 2 placebo conditions) and instructed to consume study product twice daily for 21 days. Self-report questionnaires, wrist actigraphy, pressure pain testing, and cognitive function will be assessed pre and post the experiment... Read More

Mechanisms of Deep Vein Thrombosis (DVT) and Vein Wall Fibrosis
NCT04833764
Recruiting
The goal of this study is to determine the safety and tolerability or efficacy of adjunctive treatments (including rosuvastatin 20 mg daily) in combination with standard anticoagulation therapy (Factor Xa inhibitors) in patients with lower extremity deep vein thrombosis (DVT). The efficacy of adjunctive treatments to prevent the development of post thrombotic syndrome (PTS) after DVT will be evaluated.

Augmentation of Limb Perfusion With Contrast Ultrasound
NCT03195556
Recruiting
Our laboratory has discovered that ultrasound (US) imaging together with clinically approved microbubble ultrasound contrast agents can augment limb tissue perfusion. These observations have been made in mice with and without peripheral artery disease (PAD), and also in humans where high power contrast enhanced ultrasound (CEU) was used to measure perfusion but was found also to augment perfusion by almost 2-fold. The latter human studies were performed with ultrasound protocols designed for per... Read More
