The Human Blood Cell Disorder Tissue Bank will provide a convenient, comprehensive source of tissue containing populations of human blood cells from patients with various types of lymphoid, myeloid, and erythroid proliferative diseases as well as other associated conditions. The tissue bank will continue to be an invaluable asset for understanding of the biology of multiple blood cell disorders involving several cell types as well as the physiology of normal cellular counterparts affected in these disorders. Internal and external investigators will be able to utilize this tissue to test hypotheses relating to the immunologic, virologic, genetic, and molecular properties of these abnormal cells as well as normal cells from normal unaffected family members or normal aged matched subjects to provide better comparisons.

Sexual assault can lead to devastating consequences including the development of chronic conditions including posttraumatic stress disorder (PTSD) and alcohol use disorders (AUD). Interventions delivered soon after exposure to assault can decrease the long-term negative consequences of sexual assault but existing interventions are limited in their ability to target concurrent PTSD symptoms and alcohol use and little is known about how to make best practice treatment decisions in the early period following sexual assault. A greater emphasis on transdiagnostic processes that are related to both PTSD and alcohol use, such as fear and reward systems, can elucidate mechanisms of recovery, lead to the development of more effective intervention approaches, and guide clinical decision making for patients recently exposed to sexual assault.

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

The purpose of this study is to test the effects of two dietary interventions, glycemic load and calorie restriction, on physical function, cognition, pain, fatigue, mood, and anxiety in adults with multiple sclerosis (MS). The investigators will also explore the how the diet interventions impact inflammation, immunity, and metabolic biomarkers. Read Less

Behavioral Exposure for Interoceptive Tolerance (BE-FIT) is a mechanism-informed behavioral intervention to target exercise anxiety. The three primary components of BE-FIT include: (1) exposure to feared bodily sensations and exercise; (2) prevention of safety behavior use before/during/after exercise, and (3) use of a wrist-worn activity monitor for physical activity (PA) feedback and activity goal setting. Evidence from the investigators' Stage I trial indicated that BE-FIT is feasible, acceptable, and safe and produced reductions in exercise anxiety and increased exercise outcomes (short-term moderate-to-vigorous intensity physical activity and steps/day). The investigators' present aim is to conduct a Stage II randomized-controlled trial to further evaluate the efficacy of BE-FIT in decreasing exercise anxiety in cardiac rehabilitation (CR) patients and examine whether changes in this target yield successive changes in exercise adherence outcomes.

Multiple prior studies have compared self-administered Subcutaneous Depot Medroxyprogesterone Acetate(DMPA-SC) to both provider-administered DMPA-SC and Intramuscular Depot Medroxyprogesterone Acetate (DMPA-IM) and found that continuation rates for self-administered DMPA-SC are higher. Thus far, studies investigating self-administered DMPA-SC have focused on patients presenting for contraception. Self-administered DMPA-SC has not been widely studied in patients seeking abortion and has been more extensively studied in international settings than in the US. The project will be a prospective cohort study of patients at a large, free-standing abortion clinic in Chicago, Illinois. Patients who indicate that they desire DMPA for post-abortion contraception will be recruited. They will choose either provider-administered DMPA-IM or self-administered DMPA-SC. Patients in both groups will complete a baseline survey that will collect demographic and clinical characteristics. Patients who choose self-administered DMPA-SC will receive self-injection teaching from study staff and will self-inject their first dose of DMPA-SC in the clinic. Patients who choose provider-administered DMPA-IM will receive their first dose of DMPA-IM in the clinic. Both groups will receive a prescription for three additional doses of DMPA and will receive an injection calendar. Study participants will receive a reminder prior to the start of the injection window for their second and third doses. After the injection window for the second and third doses closes, participants will complete follow up surveys. These surveys will assess whether patients received the subsequent doses of DMPA, reasons for discontinuing DMPA for patients who did not receive a dose, pregnancy status, and patient satisfaction with DMPA use. Follow up will be primarily via secure text messaging application with phone calls, email, and mail reserved for patients who cannot or prefer not to be contacted via text message. The primary outcome is continuation rates of DMPA-IM and DMPA-SC at 3 and 6 months after initiation. Secondary outcome measures include pregnancy, adverse effects, and patient satisfaction. We will also determine associations between patients' demographic and clinical characteristics and continuation of DMPA. This project will generate evidence that will support expanding access to DMPA-SC and providing patient education on self-injection, allowing for increased patient contraceptive autonomy. Read Less

This study aims to show that lack of antibiotic prophylaxis to those undergoing bladder Botox injections is not significantly inferior to administering prophylaxis. By proving this, the investigators aim to decrease antibiotic use in this setting to combat the growing issue of antibiotic resistance. Participants will be randomized to antibiotic or no treatment arm. Those randomized to the treatment arm will receive oral antibiotics for 2 days pre-treatment, on the treatment day, and 2 days post-treatment. Participants will return for a follow up appointment approximately 2 weeks after treatment to assess for urinary tract infection (UTI) symptoms. They will be called again at 6 weeks for follow up.
