Oklahoma City, OK Paid Clinical Trials

This randomized research trial studies how well serum tumor marker directed disease monitoring works in monitoring patients with hormone receptor positive Her2 negative breast cancer that has spread to other places in the body. Using markers to prompt when scans should be ordered may be as good as the usual approach to monitoring disease. Read Less

Lung cancer is the leading cause of cancer mortality among American Indians and Alaska Natives (AI/AN), and AI/AN have worse lung cancer incidence rates, survival, and death compared to the general population. Because lung cancer screening (LCS) with low-dose computed tomography (LDCT) has been shown to reduce lung cancer mortality by roughly 20%, the United States Preventive Services Task Force now recommends LCS for men and women aged 55-80 years who meet specific eligibility criteria (grade-B evidence), and subsequently the Center for Medicare and Medicaid Services (CMS) opted to cover this test. However, the uptake of LCS implementation has been slow in most healthcare systems, and LCS implementation among AI/AN has never been studied. To address this knowledge, we prose the "Tribally Engaged Approaches to Lung Screening (TEALS)" study, which is a collaborative effort between the Choctaw Nation of Oklahoma, the Stephenson Cancer Center, and the University of Oklahoma Health Sciences Center. Over the course of 5 years, TEALS will: Conduct focus groups and semi-structured interviews with CNHSA patients, clinicians, and health administrators to elucidate individual- and system-level barriers and facilitators that affect the implementation of LCS; Develop an LCS care coordination intervention that will identify eligible persons for LCS, help these patients navigate the screening process, and link them with smoking cessation services, when applicable; Measure the impact of the TEALS intervention on the receipt of screening and a set of patient- and practice-level outcomes by conducting a cluster-randomized clinical trial of LCS implementation; and Disseminate the TEALS program to other researchers and healthcare systems that serve AI/AN patients. TEALS will bridge the gap between evidence and clinical practice for LCS in a high-need, low-resource setting by intervening at the level of the healthcare system. System-level interventions for guideline implementation tend to be understudied compared to those evaluating individual-level, behavioral interventions. However, the careful development and evaluation of an LCS screening program at the level of the healthcare system would be critical to ensure that more patients can receive LCS. Our research will create a critically needed platform from which future studies could be launched that will examine how to tailor the application of the LCS guideline to the individual preferences of AI/AN patients. TEALS will establish an effective LCS program in a tribal system and thus provide a direct benefit to the Choctaw Nation by increasing LCS participation. TEALS will serve as a blueprint for establishing a sustainable and accessible infrastructure for LCS in AI/AN and other community health systems. By increasing screening for early stage lung cancer, TEALS could ultimately reduce lung cancer mortality in AI/AN communities. Read Less

This is a two-phase study that compares performance growth pre-implant with current hearing aid (HA) technology versus post-implant with a cochlear implant (CI) in children with either asymmetric hearing loss (AHL) or single-sided deafness (SSD). Post-implant performance with a CI alone is expected to outperform pre-implant performance with a HA. The study also evaluates the effectiveness of bimodal hearing defined as a CI in the poor ear and a HA in the better ear for AHL or a CI in the poor ear and normal hearing in the better ear for SSD compared to pre-implant performance. The study examines factors contributing to CI outcomes. Read Less

This first-in-human (FIH) dose-escalation and dose-validation/expansion study will assess ziftomenib, a menin-MLL(KMT2A) inhibitor, in patients with relapsed or refractory acute myeloid leukemia (AML) as part of Phase 1. In Phase 2, assessment of ziftomenib will continue in patients with NPM1-m AML. Read Less

Sepsis is life-threatening organ dysfunction caused by a dysregulated host response to infection. It is the most expensive healthcare condition to treat in United States and has a mortality rate of nearly 30%. It is widely known that exaggerated inflammation and imbalance between sympathetic and parasympathetic arms of the autonomic nervous system (ANS) contribute to progression and adverse outcomes in sepsis. The role of unchecked inflammation and unregulated ANS as a potential treatment target is an important gap in our knowledge that should be explored. Cholinergic anti-inflammatory pathway (CAP) is an intricate network where the ANS senses inflammation by vagus nerve afferents and tries to regulate it by vagus nerve efferents to the reticuloendothelial system. The central hypothesis of this pilot clinical trial is that transcutaneous vagus nerve stimulation (TVNS) at tragus of the external ear can activate the CAP to suppress inflammation and improve autonomic imbalance as measured by inflammatory cytokine levels and heart rate variability (HRV) analysis. The investigators plan to randomize patients with septic shock into active and sham stimulation groups and study the effects of vagal stimulation on inflammatory cytokines, HRV and a clinical severity score of sepsis. Both groups will continue to receive the standard of care treatment for sepsis irrespective of group assignments. The investigators hypothesize that 4 hours of TVNS will suppress inflammatory markers and improve the balance between sympathetic and parasympathetic arms of ANS as measured by HRV, resulting in improved Sequential Organ Failure Assessment Score (SOFA). The preliminary data generated from this pilot study will lay the foundation for a larger clinical trial. Read Less

The purpose of this study is to test the hypothesis that an antibody-mediated autoimmune reaction will cause symptoms of autonomic dysfunction in some patients with postural tachycardia syndrome (POTS). The investigators further hypothesize that electrical stimulation of the vagus nerve will improve POTS symptoms, autoimmunity and inflammation. Read Less

This proposal aims to determine the effects of tVNS on autonomic tone, atrial substrate and neuromodulators in patients with paroxysmal atrial fibrillation (AF), investigate the chronic effects of optimal tVNS on AF burden in patients with paroxysmal AF over a 6-month period, compared with sham stimulation, and identify physiological and biochemical markers of response to chronic tVNS.

Nonalcoholic fatty liver disease (NAFLD) is now the most common liver disease worldwide and affects nearly 40% of obese youth and up to 10% of the general pediatric population. Some features of NAFLD are similar in children and adults, yet fibrosis and inflammation are more common in the portal zone and occur earlier in pediatric NAFLD patients than adults. This portends a rapid progression to end-stage liver disease in early adulthood. For the majority of children with NAFLD, mechanisms driving the origin and rapid progression of disease remain unknown. Thus, there is a critical, unmet need to study the specific underlying patterns of metabolic and molecular changes in the liver underlying the development and progression unique to children with NAFLD. This proposal will test the hypotheses that children with NAFLD have excess glucose and lipid produced by the liver, that those events are regulated by specific variations in the amount and location of RNAs and proteins in liver, and that the concentration of specific micro-RNAs in the blood can be used as a biomarker for NAFLD in pediatric patients.

Atrial fibrillation (AF) is the most common arrhythmia and the prevalence increase with age. Autonomic nervous system play a critical role in the initiation and maintenance of AF. The intrinsic cardiac autonomic nervous system includes ganglionated plexus (GP) modulate the level of parasympathetic activity to the heart. Experimental and clinical studies suggest that GP activation plays a significant role in clinical AF in both the initiation of and the maintenance of AF. Synaptic plasticity is defined as the ability of synapses to change their strength of transmission. Plasticity of synaptic connections in the brain is a major focus of neuroscience research, as it is the primary mechanism underpinning learning and memory. Beyond the brain however, plasticity in peripheral neurons is less well understood, particularly in the GP neurons innervating the heart. The ability of these neurons to alter parasympathetic activity suggests that plasticity may indeed occur at the synapses formed on and by GP neurons. Such changes may not only fine-tune autonomic innervation of the heart, but could also be a source of maladaptive plasticity during atrial fibrillation. Low level tragus stimulation (LLTS) has been shown to decrease AF burden among patients with paroxysmal AF. However, the exact mechanism remains unclear. The objective of this study is to examine changes in synaptic density of GP neurons in patients with paroxysmal AF and persistent AF compared to those without AF undergoing cardiac surgery. In addition, we aim to examine the effect of LLTS on the synaptic plasticity of the GP neurons. A group of patients undergoing open heart surgery will be randomized to active LLTS for 30 min (pulse width of 200 μs, amplitude of 20 mA and a pulse frequency of 20 Hz) or no stimulation. Biopsy from GP tissue will be taken immediately after stimulation and histological staining for choline acetyl transferase (ChAT), tyrosine hydroxylase (TH) and synaptophysin will be performed to examine synaptic plasticity. Understanding the effect of LLTS on GP SP will help to determine whether changes in synaptic plasticity can increase or decrease autonomic tone of the heart, and its role in generating the aberrant electrical impulses in the GP around the pulmonary veins that can trigger and drive AF.
