Gastrointestinal Response of Pediatric Cystic Fibrosis Patients on Mediterranean Diet

There is no study to date that has evaluated the impact or effect of a Mediterranean diet in children with CF. The goal of this study would be to help provide better guidance around questions the investigators, as CF care providers continue to receive from patients and families about how to best promote overall health in pediatric cystic fibrosis from a dietary perspective. Currently, the updated nutritional recommendations are variable and broad. Parents continue to search for more concrete guidance about how best to promote long-term health given the ever-increasing life expectancy of cystic fibrosis patients in this new area of advanced therapeutics. Given the changing landscape of the CF care in general, children are less likely to struggle with early life malnutrition, and it is becoming increasingly clear that high fat, high calorie diets are not beneficial nor are necessary for all children with CF.

Testing a Mammography Decision Intervention in a Rural Setting

The overall objective of this COBRE pilot project is to enhance the design of a 3-arm cluster randomized trial that will test the efficacy and mechanism of effect of the MyMammogram DA with or without a provider communication intervention. This will be accomplished through two aims: (1) Refine, with community partner input, a clinical trial protocol to optimize engagement among patients and primary care providers (PCPs) practicing in rural settings. In consultation with patients, PCPs, and informatics experts, the study team will refine site selection, randomization, patient and PCP recruitment, and data collection protocols to meet the needs of the rural health care delivery system and participants. The result of this aim will be a modified protocol and intervention strategy that is acceptable to partners. (2) Adapt and test trial and intervention implementation features to achieve protocol acceptance and adherence. The investigators will pilot the adapted three-arm randomized trial protocol in rural primary care settings that compares the MyMammogram DA with or without a risk summary provided to the PCP pre-visit, relative to usual care. Implementing the trial in two phases (n=15 each) will systematically identify barriers and facilitators to trial participation to refine protocols. Participants will receive acceptability surveys and investigators will conduct qualitative interviews with patients and PCPs to understand experiences with trial implementation from multiple perspectives.

A Randomized Two-Arm Proof of Concept Study Testing A Novel Approach to Exercise Promotion Based on Affect-regulation

The goal of this clinical trial is to test the effect of an affect-based exercise prescription on moderate-vigorous physical activity participation among survivors of breast cancer who completed primary treatment within the last 5 years. The main questions it aims to answer are: 1. Do at least 50% of participants assigned to the affect-based exercise prescription engage in ≥90 minutes of moderate-vigorous physical activity by the end of 12-weeks follow-up? 2. What level of satisfaction do breast cancer survivors who receive the affect-based exercise prescription report relative to breast cancer survivors who receive an effort-based exercise prescription. 3. What proportion of participants assigned to the affect-based exercise prescription stay enrolled in the study relative to the number of participants who stay enrolled in the effort-based exercise prescription. All participants will: * Be assigned to either the Affect-based exercise prescription or the Effort-based exercise prescription. * Participate in two meetings with a member of the study team meant to help them get started increasing weekly exercise. These meetings are the same for all participants. * Be asked to wear an activity monitor and respond to brief surveys for 10 straight days at 4 points in time: Baseline, 2weeks, 6weeks, and 12weeks.

iPath for CP Pilot

Depression is a significant problem in care partners of people living with dementia; despite the expansion of options for accessing evidence-based treatments, most care partners of people living with dementia are not screened for depression and do not receive treatment. The objective of this project is to identify a screening method for depression that is feasible and acceptable to care partners and to adapt an innovative pathway to online evidence-based treatment for depression (iPath\*D) as a means of increasing mental health literacy, screening rates and treatment access for care partners of people living with dementia. The results are expected to have a major positive impact by providing proof-of-principle for the use of an online pathway to evidence based treatment with the potential for reaching an unprecedented number of care partners who have unmet mental health needs.

Low-Dose Naltrexone for the Treatment of Painful Diabetic Neuropathy

Diabetes affects more than 30 million people in the United States and is a leading cause of morbidity. Over 25% diabetics also suffer from debilitating painful diabetic neuropathy in the lower legs and feet. This pain can be severe, difficult to control, and have a significant negative impact on quality of life. Opioid medications have historically been a mainstay of treatment for this pain, despite the risks. As the death toll from the U.S. opioid epidemic continues to rise, the need for quality alternative non-opioid medications to treat pain becomes more urgent. One of these potential medications is Low-Dose Naltrexone (LDN). This drug is reported to work by enhancing the body's natural pain relieving mechanisms and decreases inflammation by targeting specific cells called microglia which have been shown to influence chronic pain. LDN has been shown to be a safe medication with minimal side effects. Its efficacy has been demonstrated in other painful conditions but has never been fully studied for treating painful diabetic neuropathy. The goal of this randomized, placebo-controlled trial is to determine if LDN is effective for treating the pain caused by diabetic neuropathy. LDN's mechanism of action is well suited to treating painful diabetic neuropathy, and LDN shows significant promise as a safe, non-opioid alternative that can decrease pain and improve quality of life for those suffering from this painful condition.

In Vivo Imaging of the Olfactory Epithelium Using Confocal Laser Endomicroscopy

This research is being done to better characterize the part of the nose that helps us smell. Currently, the only ways to study smell loss mostly rely on how people report it, rather than being able to see the underlying structures directly. In this study, we will use a special microscope (Confocal Laser Endomicroscopy (CLE)), originally developed for brain tissue, to look at the part of the nose that helps to detects smell. We hope to identify the tiny structures in that area and see how they might be different in people who have smell loss compared to those who do not.

A Study of Tetrathiomolybdate (TM) Plus Capecitabine

There are two parts to this study. It is a phase 1b followed by a randomized phase 2 study to assess whether adding 3 years of adjuvant tetrathiomolybdate (TM) to standard 6 months treatment of adjuvant capecitabine and pembrolizumab in high risk for relapse triple negative breast cancer. In the phase 1b part of the study, TM is added to adjuvant capecitabine and pembrolizumab in high risk for relapse triple negative breast cancer (RCB 2, 3, risk for relapse \>60% at 5 years) after completion of neoadjuvant chemo-immunotherapy and surgery to establish the safety of the combination. This will be followed by a randomized phase 2 clinical trial of adjuvant TM and capecitabine vs capecitabine alone. If pembrolizumab was administered in the neoadjuvant setting, it may be continued in the adjuvant setting per investigator discretion.

Psychological Trauma, Post-Traumatic Stress Disorder, and Resilience in Adults With Congenital Heart Disease

The purpose of this study, entitled "Psychological trauma, post-traumatic stress disorder, and resilience in adults with congenital heart disease in a large population sample", is to evaluate for exposures during a lifetime with congenital heart disease that may be associated with higher likelihood of developing PTSD. Primary aim: \- Identify individual patient characteristics (medical, psychosocial, socioeconomic, etc.) that are associated with a diagnosis of PTSD. Secondary aims: * Calculate the prevalence of those meeting PTSD criteria in the ACHD population using the "gold standard" diagnostic clinician interview, while using the same data to validate a PTSD screening self-report survey in the ACHD population. * Determine the role of resilience in ACHD patients using a validated screening survey to assess its protective role toward PTSD. Hypotheses: * There are certain exposures (e.g. post-surgical pain, ICU delirium, bullying due to CHD) that are associated with a higher incidence and odds of meeting PTSD criteria. * "Gold standard" diagnostic interviews will most accurately estimate the prevalence of PTSD in ACHD which has been overestimated on prior screening-based studies, although the scope of the problem is still great. * Patients with a higher resilience score will show an association with a lower risk of PTSD.
