Intravesical immunotherapy or chemotherapy for non-muscle invasive bladder cancer is a well-established treatment for preventing or delaying tumor recurrence after bladder tumor resection. For high-risk non-muscle invasive bladder cancer, immunotherapy in the form of intravesical Bacillus Calmette-Guérin (BCG) can be effective as first-line, nevertheless, the response rate to BCG is suboptimal with many patients failing treatment. Following BCG-failure, however, very few effective therapeutic options exist besides life-changing cystectomy. In addition, nationwide shortages of BCG have pushed the use of alternative intravesical therapies for non-muscle invasive bladder cancer. At Banner University Medical-Tucson, the use of intravesical Gemcitabine is considered as standard treatment for patients with bladder cancer who are unable to get BCG or have failed prior BCG treatment. The role of Gemcitabine as treatment for NBMIC is poorly understood. The purpose of this study is to gain a better understanding of the use of Gemcitabine intravesical chemotherapy for non-muscle invasive bladder cancer in a prospective cohort of patients. Read Less

As the population of cancer survivors increases substantially, meeting the health care and psychosocial needs of this population has become a national priority. After treatment ends, cancer survivors still experience a range of physical and psychological symptoms that require management. The post-treatment period can present new challenges for many survivors as they encounter communication gaps in the transition from oncology to primary care, leaving unmet needs for information and management of lingering symptoms. The role of informal caregivers remains important during this post-treatment period and psychosocial interventions that meet the needs (e.g., information, symptom management) of both members of the dyad are highly valuable to caregivers and survivors. Many geographic and social determinants of health care use (e.g., distance to specialty care centers, available primary care providers, and public transportation) make access to care and adherence to recommended healthcare guidelines difficult for survivors and caregivers, especially those who reside in rural areas. Rural residents with cancer and their caregivers during the post-treatment period are underrepresented in symptom management research. To address the unmet needs (e.g., information, symptom management) of cancer survivors and their caregivers after cancer treatment, this team has developed, tested, and investigated two telephone delivered interventions for survivors and their caregivers: Symptom Management and Survivorship Handbook (SMSH) and Telephone Interpersonal Counseling (TIP-C).

In this study, a novel placental membrane product Matrion™ (LifeNet Health, Inc., Virginia Beach, VA) will be used as a treatment for subjects with diabetic foot ulcers. Matrion is composed of placental membrane derived from donated human birth tissue containing both the innermost amniotic layer and the outermost chorionic layer, inclusive of the trophoblast layer. Matrion is minimally processed and disinfected using a proprietary decellularization technology and terminally sterilized that safely renders the placental membrane acellular and sterile for its intended surgical applications.

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.

The overall objective of this clinical study is to determine the feasibility of breast CT for breast density assessment and association of CT-derived density measures with metabolic syndrome in overweight/obese Mexican-origin women in Southern Arizona. These evaluations will help support follow-up clinical research utilizing breast density acquired by breast CT as a surrogate endpoint biomarker to evaluate breast cancer preventive strategies. The long-term goal of these research efforts is to develop safe and effective preventive strategies to reduce obesity-associated breast cancer burden in our catchment area. Read Less

Cancer in general, and breast cancer in specific, is a significant health problem in the USA and the rest of the world. With the improvement of new surgical approaches and chemotherapies to manage breast cancer, the number of patients with breast cancer are now living longer. This great achievement created an unexpected problem. For some breast cancer patients, with bone metastases, the pain is worse than the cancer. The golden standard to manage pain is opioids. Patients with cancer-induced bone pain are now taking increasing doses of opioids to control their pain. Sadly, opioids come with significant side effects that limit the amount of opioids that can be safely given. Many attempts have been tried to create better regiments for pain control to lower the need for opioids. There has not been significant success in that area. A better approach would be to add a non-opioid agent that has dual mechanisms of action. This may create synergism to better control pain while lowering the doses of opioids needed and lowering side effects. Sulfasalazine poses such quality it is a safe anti-inflammatory drug with established safety profile. It has been in use for over 50 years for the treatment of inflammatory conditions such as arthritis. In addition to its anti-inflammatory characteristics, sulfasalazine has the capacity to decrease the survival of cancer cells, also to lower the number of inflammatory mediators released by cancer cells. In short, sulfasalazine inhibit the influx of cysteine into cancer cells and the efflux of glutamate. Cysteine is needed for cell survival against oxidative stress, while glutamate activate pain receptors. Therefore, sulfasalazine will act as anti-inflammatory, an agent to accelerate cancer cells death and decreasing the released glutamate which activate pain receptors. This one agent with 3 mechanisms of actions may lower the amount of opioid needed for these patients while maintaining or improving their pain. Lowering of opioid dosing may also improve the side effects associated with opioid use. The purpose of this trial is to co-administer sulfasalazine with opioids to cancer patients and characterize their pain and the opioid use. Our hypothesis is that adding sulfasalazine to the pain medication, will lower the amount of opioids used and lower the side effects. This may improve the quality of life for patients and decrease the risks of using high amount of opioids for the patients, their families, and society in general. Read Less

In the proposed study, the investigators will examine the effectiveness of Bodie in Motion (BIM) program in improving the body image, eating concerns, and overall psychological well-being, in a racially/ethnically diverse group of female and male-identifying athletes with body image concerns. Based on previous research, participating athletes should have direct and immediate Well-Being (i.e., mental health) benefits from their involvement in BIM. Read Less

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
