This is a double-blind, saline-controlled, and randomized study with blinded assessments using a single dose. Subjects that have a current diagnosis of chronic lumbar disc disease and meet eligibility criteria will be enrolled. Chronic lumbar disc disease is defined as back and/or radicular pain with degeneration of the disc confirmed by patient history, physical examination, and radiographic measures such as computed tomography (CT), magnetic resonance imaging (MRI), plain film, myelography, discography, or other acceptable means.

The NOURISH-OK Study will identify how food insecurity contributes to insulin resistance, an important surrogate marker of many co-morbidities in HIV disease, using an integrated framework to identify key leverage points for insulin resistance. Drawing from these pathways, this study will adapt and evaluate a community-driven, science-informed "food as medicine" intervention designed to lower insulin resistance through healthy food access, food utilization skills, and other self-care behaviors. Knowledge gained from this study can benefit those living with HIV through the prevention and more effective management of pre-diabetes, diabetes, obesity, and non-alcoholic fatty liver disease.

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: 1. 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; 2. 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; 3. 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 4. 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

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

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.

The extent and depth of the ongoing opioid crisis are well known and many interventions are under way in the United States and other countries to alleviate its devastating impact on individuals and the society. To address specific challenges of pain and opioid management (POM) in older and vulnerable adults, the investigators will design and implement a multi-faceted, person-centered, and scalable opioid use disorder (OUD) management program in Oklahoma primary care practices. The investigators expect that the rigorously designed and evidence-based program will establish and disseminate innovative solutions for pain and opioid management in high-risk, older and vulnerable populations living with chronic pain. The proposed initiative will help primary care practices optimize pain management approaches in older adults through an integrated and trans-disciplinary application of innovations in multi-modal pain management, pain mechanism-based pharmacotherapy, patient goal-oriented care, implementation science, evidence-based quality improvement methodology, and community-engaged design.
