Tucson, AZ Paid Clinical Trials

This study aims to compare the effectiveness of the use of no topical anesthesia, topical coolant, and the use of vibration in the reduction of pain during trigger finger injections. This will be done by randomizing patients who are diagnosed with trigger finger, warrant and choose to continue with a steroid injection into each of the respective anesthetic (or lack thereof) methods described. After conducting this and gathering data on the subjects pain felt, we will compare the analgesia from each of the anesthetic methods. Read Less

The DISCORDANCE TAVR study will determine the discordance between echocardiography-derived and invasive transaortic gradients, as determined by a consistent and reproducible technique (Standardized Invasive Hemodynamics) post-TAVR. Read Less

Enhanced Recovery After Surgery (ERAS) is a set of evidence-based guidelines that may be used during perioperative care for cesarean section. While there is good evidence that following ERAS protocols benefits postoperative recovery, less is understood about the effect on the fetus and neonate. This will be a randomized equivalence trial to determine if drinking a carbohydrate rich drink prior to cesarean section has an effect on neonatal glucose. Read Less

This clinical trial uses transcranial direct current stimulation (tDCS) using the patented tKIWI system to safely reduce self-reported chronic pain with little to no side effects to improve our understanding and ability to accurately diagnose pain disorders which would facilitate the development of pharmacologic and non-pharmacologic treatment modalities using deep learning architecture built into the tKIWI.

Substance use disorder (SUD) affects more than 23 million Americans and claims more than 70,000 lives annually. With 40-60% relapse rate, SUD patients are high hospital utilizers, 65% of the incarcerated population, and are at high-risk for overdose and deaths. There is a pressing need for research in this area to advance beyond traditional pharmacological and behavioral therapies toward a greater focus on the mechanisms of risk for relapse and to improve personalization for SUD treatment. Neuromodulation has shown promise to stimulate neuronal growth without any of the side effects of medications or electroconvulsive therapy. Using transcranial direct current stimulation (tDCS) to modulate cortical activity has shown to be a viable therapy in medicine-resistant depression, to reduce opioid cravings, and impulse control. The proposed research plans to recruit 30 subjects with a history of substance use disorder (SUD). This may include a history of addiction to opioids, cocaine, and barbiturates. Addiction to alcohol and cannabinoids (marijuana) will be excluded from this study. Following recruitment and consent, the subject will be administered an EEG, Acceptance Commitment Therapy exercise followed by EEG, and a BIS-11 Survey measuring levels of impulsivity. During the next week, the patient will undergo 5 visits consisting of a pre-EEG, tDCS, and post-EEG. Half of the subjects (n=15) will receive treatment, while the other half will be in a sham group. After the completion of the 5 tDCS visits, the patient will again be administered an EEG, ACT exercise followed by EEG, and a final BIS-11 survey measuring for end impulsivity levels. Read Less

Insomnia is generally believed to be caused by excessive arousal of the brain and body. Rather than transitioning normally and quickly from wakefulness to sleep, individuals with insomnia tend to enter into a self-perpetuating cycle of self-referential thought and arousal. Brain imaging research has shown that these same internally focused self-reflective thoughts tend to activate a core system in the brain known as the Default Mode Network (DMN). The DMN is usually active when a person is internally focused, such as during daydreaming or mind wandering, but tends to be deactivated when the brain is focused on the external environment. The investigators hypothesize that excess activation and connectivity of this brain network may perpetuate internal conversations, worry, and rumination, preventing individuals with insomnia from falling asleep quickly and remaining asleep. Therefore, the goal of the present study is to use a brain stimulation technique known as transcranial magnetic stimulation (TMS) to target the DMN and slightly reduce its activation before bed. This should result in an easier time falling asleep. For this study, the investigators will recruit 20 healthy individuals and have them sleep in the lab on two occasions. On one occasion, they will be stimulated with a type of TMS called continuous theta burst stimulation (cTBS), which will be targeted toward their DMN. They will then try to sleep in the lab while the investigators record their brain waves using a technique known as polysomnography (PSG). On the other occasion, these same individuals will undergo the same procedure, but the TMS machine will be in a deactivated mode to present a "sham" stimulation. Participants will again try to sleep in the lab following the sham treatment while being recorded with PSG. Neither the participants nor the experimenters will know which condition the participant is receiving at the time. This will only be revealed later. Additionally, all participants will receive a brain scan just before and just after the TMS procedures so that the investigators can examine changes in brain connectivity and chemistry. The investigators expect that the participants will sleep better following the cTBS than following the sham condition and that this will be associated with measurable differences in their brain connectivity and brain chemistry. If effective, this project would have identified an innovative and novel approach for improving sleep without using drugs. Read Less

The present study D5272C00001 (Legacy # 3151-201-008) seeks to evaluate the efficacy and safety of brazikumab versus placebo in patients with moderately to severely active UC and will include assessments of clinical responses as demonstrated by improvement of symptoms and of colonic mucosal appearance as observed on endoscopy.

The main objective of this research project is to provide a comprehensive clinical database of patients with Alzheimer's disease (AD) and other forms of dementia, individuals with mild cognitive impairment (MCI), and age-matched normal controls. The study will also attempt to identify cognitively normal individuals at genetically defined risk for Alzheimer's disease through genetic screening. All participants are seen annually. Autopsies to establish diagnoses in patients with dementia, patients with mild MCI, and cognitively normal elderly control subjects will also be conducted. Read Less
