NCT04652687
Registry is to observe and trend patterns of care and outcomes for patients treated with VIA Disc NP.
NCT06410339
The objective of this study is to assess whether recreational rock climbers experience thickening of the flexor digitorum tendon in the 2nd 3rd and 4th fingers. In these fingers the study will also assess whether there is thickening of the A2 annular pulley and if there is a measurable increase in the tendon to bone distance at the level of the A2 pulley when the fingers are placed into flexion against mild resistance. This study aims to provide clinicians with an understanding of how exposure to rock climbing can lead to chronic anatomical changes to the soft tissue structures of the finger. These changes have been demonstrated in the elite rock climber population, but have yet to be studied in the much larger and growing recreational rock climbing population which consisted of nearly 10 million participants in 2021. If significant, these anatomical variations might guide the assessment of imaging and clinical decision making when managing finger injuries in patients with exposure to rock climbing. Portable ultrasound probes will be used to scan and measure the dimensions of various soft tissue structures in the hands of both rock climbers and a control population, this data will be paired with data collected in a brief survey asking about exposure to rock climbing, history of finger injuries, and style of climbing.
NCT04334317
It is hoped that TAK-071 will help people with Parkinson's disease to walk with better balance. The main aim of the study is to check if there is a difference in how participants walk after treatment with TAK-071. Another aim is to see if it improves how participants think and remember. At the first visit, the study doctor will check who can take part. Participants who can take part will be picked for 1 of 2 groups by chance. Both groups will have 2 treatments but in a different order. The treatments are TAK-071 tablets or placebo. In this study, a placebo will look like the TAK-071 but will not have any medicine in it. One group will take TAK-071 for 6 weeks, have at least a 3-week break, then take a placebo for 6 weeks. The other group will take a placebo for 6 weeks, have at least a 3-week break, then take TAK-071 for 6 weeks. The participants will not know the order of their 2 treatments, nor will their study doctors. This is to help make sure the results are more reliable. The participants will visit the clinic at the beginning and end of each treatment for a check-up. 14 days after the 2nd treatment, clinic staff will telephone the participants for a final check-up.

NCT02320266
Deep brain stimulation (DBS) is an FDA approved, and widely used method for treating the motor symptoms of Parkinson's disease (PD), Essential Tremor (ET), Dystonia and Obsessive Compulsive disorder (OCD). Over 100,000 patients worldwide have now been implanted with DBS devices. Current approved methods to locate the DBS target regions in the brain use a combination of stereotactic imaging techniques and measurements of the electrical activity of brain cells. As part of the standard clinical technique, electrical data are collected from individual nerve cells. The target brain region emits unique electrical signals. At certain brain locations, during DBS surgery, additional electrical data that are generated in response to sound will be collected. Regions of the brain that have a decreased response to repeated sound (auditory gating) may be important DBS targets for improving thinking. The aims are (i) during DBS surgery, in addition to EEG, use microelectrodes in the brain to find brain regions, along the normal path to the DBS target, where auditory gating occurs and then (ii) determine if stimulation of the identified region(s) alters auditory gating measured by EEG. Also an additional aim (iii) is to measure electrical activity at the scalp with EEG to characterize auditory gating in patients before and after DBS surgery and also a healthy control population.
NCT05520905
Youth represent the largest proportion of new HIV infections in Colorado, reflective of their inadequate access and uptake of pre-exposure prophylaxis(PrEP)for HIV prevention. Colorado's 2019 HIV/AIDS Prevention Program state-wide review of PrEP barriers showed PrEP eligible individuals do not access PrEP services due to lack of interest, not wanting referral to a navigator, and low estimation of HIV risk. The overall goal is to provide youth at higher risk for HIV with an effective youth informed telemedicine delivery of PrEP (TelePrEP) that addresses PrEP barriers and contributes to ending the HIV epidemic in Colorado. The primary objective will be proportion of youth retained on PrEP 12 months after initiation. The hypotheses are that a TelePrEP model for youth will be acceptable and feasible and will result in successful initiation, persistence and retention on oral PrEP.
NCT02507687
This study will evaluate the intraocular pressure (IOP)-lowering effect and safety of bimatoprost SR compared with selective laser trabeculoplasty in patients with open-angle glaucoma or ocular hypertension who are not adequately managed with topical IOP-lowering medication for reasons other than medication efficacy (e.g., due to intolerance or nonadherence).

NCT02728102
The study is designed as a Phase II, multicenter trial of vaccination with Dendritic cell/myeloma fusions with granulocyte macrophage colony-stimulating factor (GM-CSF) adjuvant plus lenalidomide maintenance therapy versus maintenance therapy alone or with GM-CSF following autologous transplant as part of upfront treatment of multiple myeloma (MM). It is hypothesized that the dendritic cell myeloma vaccine will result in improved response in patients with multiple myeloma after autologous Hematopoietic Cell Transplant (HCT).
NCT04503759
This prospective registry was designed as an observational study to ascertain how commercially available NanoBone products are being used by surgeons performing foot and ankle surgery which involves bone grafting, as well as determining relevant patient outcomes.
NCT03674307
The Canadian Australasian Randomized Trial of Screening Kidney Transplant Candidates for Coronary Artery Disease (CARSK) will test the hypothesis that eliminating the regular use of non-invasive screening tests for CAD AFTER waitlist activation is not inferior to regular (i.e., annual) screening for CAD during wait-listing for the prevention of Major Adverse Cardiac Events. Secondary analyses will assess the impact of screening on the rate of transplantation, and the relative cost-effectiveness of screening.

NCT01824082
When a limb is traumatically severed, pain perceived in the part of the body that no longer exists often develops. This is called "phantom limb" pain, and is different from "stump" pain, which is pain within the part of the limb that remains intact. Unfortunately, phantom pain resolves in only 16% of people, with the rest experiencing this pain for the remainder of the lives. There is currently no reliable treatment for phantom limb pain. The exact reason that phantom limb pain occurs is unclear, but when a nerve is cut-as happens with a traumatic amputation-changes occur in the brain and spinal cord that actually worsen with increasing phantom pain. These abnormal changes may often be corrected by putting local anesthetic-termed a "peripheral nerve block"-on the injured nerve, keeping any "bad signals" from reaching the brain, with resolution of the phantom limb pain. However, when the nerve block ends after a few hours, the phantom pain returns. But, this demonstrates that the brain abnormalities-and phantom pain-that occur with an amputation may be dependent upon the "bad" signals being sent from the injured nerve(s), suggesting that a very long peripheral nerve block-lasting many days rather than hours-may permanently reverse the abnormal changes in the brain, and provide lasting relief from phantom pain. Until recently, extending a peripheral nerve block beyond 16 hours was unrealistic. However, a treatment option called a "continuous peripheral nerve block" is now available. This technique involves the placement of a tiny tube-smaller than a piece of spaghetti-through the skin and next to the nerves supplying the amputated limb. The tiny tube may be placed with minimal discomfort in about 15 minutes. Numbing medicine called local anesthetic is then infused through the tube, blocking any signals that the injured nerve sends to the spinal cord and brain. Using a small, portable infusion pump, this prolonged nerve block may be provided in individuals' own homes. The ultimate objective of the proposed research study is to determine if a 6-day continuous peripheral nerve block provided at home is an effective treatment for persistent phantom limb pain following a traumatic limb amputation. The primary hypothesis (what the researchers predict) is that phantom limb pain intensity will be significantly decreased 4 weeks following treatment with a 6-day continuous peripheral nerve block.
