Oregon Clinical Trials

While the scientific understanding of pharmacogenomics is quickly accelerating, its translation to clinical decision-making (especially in psychiatric practice) has progressed more slowly. In an effort to begin to bridge this translational gap, genetic testing has been developed for various and commonly existing psychiatric disorders, such as major depression, schizophrenia, bipolar disorder, and pain syndromes to improve the safety of prescribing psychotropic medications for these disorders. This genetic testing incudes several pharmacodynamics and pharmacokinetic genetic factors, such as the cytochrome P450 1A2 gene (CYP1A2); the cytochrome P450 2B6 (CYP2B6) gene; P450 2D6 gene (CYP2D6); the cytochrome P450 2C9 gene (CYP2C9); the cytochrome P450 2C19 gene (CYP2C19); uridine-glucoronyl-transferase 2B15 (UGT2B15) gene; the serotonin transporter gene (Solute Carrier Family 6 Member; SLC6A4); p-glycoprotein ( ATP-binding cassette sub-family B member 1; ABCB1) transporter gene; the serotonin 2A receptor gene (HTR2A); the serotonin 2C receptor (HTR2C) gene; serotonin 1a receptor (5HT1a) gene; dopamine 1 receptor (DRD1) gene; dopamine 2 receptor (DRD2) gene; adrenergic alpha-2A receptor (alpha-2A) gene; opioid mu (opioid receptor mu 1; OPRM1) receptor gene; dopamine synthesis gene (ankyrin repeat and kinase domain containing 1; ANKK1); dopamine metabolizing enzyme [Catechol-o-methyltransferase (COMT]) gene; kainite receptor gene (glutamate ionotropic receptor kainate type subunit 4; GRIK4); folate (methylenetetrahydrofolate reductase; MTHFR) gene; sodium channels (sodium voltage-gated channel alpha subunit 2; SCN2A) gene. The interpretive report is based on copies of these multiple informative genes. The investigators are proposing to utilize comprehensive genetic testing to select more genetically-informed psychotropic medications to enhance their effectiveness in real-world patients with psychiatric illnesses such as schizophrenia, major depression, bipolar affective disorder as well as pain in a state hospital setting. The investigators plan to use genetic testing offered by Admera® for major classes of psychotropic medications. The investigators hypothesize that genetic testing will demonstrate clinical benefits by improving state hospital patients' response and decreasing their adverse effects. The proposed study will be conducted in a total sample of 60 subjects diagnosed with schizophrenia, major depression, bipolar affective disorder as well as pain at the Oregon State Hospital, Salem Oregon over a total period of 24 months Read Less

The current project is a safety and health intervention focused on sleep and fatigue among truck driver teams (pairs), where one driver sleeps in a moving vehicle while the other partner drives. This study is conducted within the Oregon Healthy Workforce Center (OHWC), a NIOSH Center of Excellence in Total Worker Health. We will evaluate engineering and behavioral interventions to improve sleep, reduce fatigue, and impact Total Worker Health. An enhanced cab intervention will alter whole body vibrations during driving and sleep periods, and includes a therapeutic mattress system and an active suspension seat. The enhanced cab will be evaluated alone and in combination with a behavioral sleep intervention adapted from our effective SHIFT (Safety &Health Involvement For Truckers) program. The interventions prioritize hazard reduction according to the hierarchy of controls, and will be evaluated with a randomized controlled design. Read Less

Pre-clinical studies suggest that the third generation tyrosine kinase inhibitor ponatinib can result in microvascular angiopathy and acceleration of atherosclerosis. This study is intended to examine for myocardial microvascular angiopathy and changes in carotid plaque in patients receiving ponatinib as part of their clinical care. Read Less

In a recent study it was found that neurologist care for Parkinson's provides a 20% reduction in nursing home placement, hip fracture, and death (Willis 2011). However, as the authors recognized, the investigators don't know what it is about expert care that delivers this benefit. The Parkinson's Foundation's Quality Improvement Initiative was designed to identify the components of great care that yield great outcomes. By capturing demographics, clinical interventions and outcomes over time from multiple centers across the U.S, Canada and internationally, the best care practices from different clinics and different healthcare systems will be analyzed.

- Brief Summary: Prospective, cohort, open-label study. The cohort consists of people who have a chronic balance dysfunction due to a mild to moderate traumatic brain injury (TBI). All participants will participate in a 14-week PoNS Treatment protocol - a combination of symptom specific physical exercises and repeated use of the PoNS device. Subjects who meet the initial screening entrance criteria will be scheduled for a baseline assessment to evaluate balance and gait. Subjects will then begin the PoNS Treatment program and re-perform some assessments at 2, 5 and 14 weeks evaluating their functional improvements. Read Less

When people break their arm and arrive at Oregon Health and Science University's Emergency Department (OHSU ED), they are treated with a short-term means of immobilizing their broken arm. The two most common ways of stabilizing the broken parts of the arm are 1) with a plaster-based coaptation splint, or 2) with a soft cloth sling and swathe. These hold the arm steady until the patient can schedule an appointment with the OHSU Orthopaedic Trauma clinic where they will receive definitive evaluation and stabilization/fixation. In much of the orthopaedic literature coaptation splints are the default immobilization method. The investigators hypothesize however, that sling and swathe immobilization may be equally effective for short term stabilization, while being faster to apply, and more comfortable for the patient. This randomized, unblinded prospective study will follow the satisfaction, quality of life and limited functional outcomes of all enrolled participants during the first week following their injury.

This is an observational, multicenter study to determine the prevalence of Cerebrotendinous Xanthomatosis (CTX) in patient populations diagnosed with early-onset idiopathic bilateral cataracts. Patients who are potentially eligible for study participation will be identified through a chart review of patients who were seen at each study site prior to that site's initiation, or by entering care at the site while the site is participating in the trial.

This is a randomized, controlled, cross-over study on the effects of consumption of Deepure puerh tea extract (PTE) on glucose tolerance and metabolic markers. Read Less

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 perfusion imaging and not for flow augmentation. In this study, we will measure the degree to which limb perfusion is augmented with specific therapeutic CEU settings that are still within the FDA-approved limits with regards to US power and contrast dosing.

The overall aim of this study is to determine whether non-invasive imaging with myocardial contrast echocardiography using can provide information on the presence and spatial extent of recent myocardial ischemia by non-invasive echocardiographic imaging. Read Less

This study represents an important step to validate the use of contrast-enhanced ultrasound (CEU) as a clinical research tool that can be used as a biologic readout of new therapies for Peripheral Artery Disease (PAD), and as a clinically-reasonable method for assessing impact of revascularization. The primary aim is to establish that CEU limb perfusion imaging can be used to accurately assess therapeutic improvements in tissue perfusion that are linked to symptom improvement. Read Less
