Recent studies have shown that transthyretin amyloidosis (ATTR) can sometimes cause a type of heart failure where the pumping function of the heart is normal, also known as Heart Failure with Preserved Ejection Fraction (HFpEF) or diastolic heart failure. In this single center diagnostic study, we will evaluate for ATTR in patients with HFpEF in order to to determine how frequently this occurs and how we can predict which heart failure patients may have TTR amyloidosis. Our goal is to identify amyloidosis in heart failure patients earlier so that they can start treatment. Read Less

The researchers are doing this study to see if one session of high-dose contrast-enhanced MRI-guided SBRT (stereotactic body radiation therapy) is effective for colorectal cancer that has spread to the liver. The researchers will evaluate how well the study treatment can prevent the liver metastasis from growing and spreading. In addition, they will see whether it causes any side effects and whether there are any characteristics of the research MRI images that can predict response to treatment. Read Less

The goal of this study is to research Dupilumab, an FDA approved medication in treating patients diagnosed with Eosinophilic esophagitis (EoE). The drug works by controlling allergic inflammation of the esophagus. The esophagus is a food pipe that transfers food from the mouth into the stomach. Participants with EoE have dysfunction of the muscle of the esophagus (impaired peristalsis) that is not favorable for the transport function. Main question this study aims to answer is: Whether Dupilumab helps improve muscle activity of the esophagus in participants with EOE? Participants will: Take Dupilumab every week for 12 weeks. Visit the clinic before and after starting the medication. Keep a diary of symptoms. Read Less

CMD can be inherited in an autosomal dominant or recessive trait. CMD may also be caused by de novo mutations. The goal of this study is to identify genes and regulatory elements on chromosomes that are the cause for CMD. The investigators also study blood samples and tissue samples from patients to learn about the processes that lead to this disorder. The investigators long-term goal is to find mechanisms to slow down bone deposition in CMD patients. Read Less

The goal of this study is to test a novel intervention for children ages 6-11 with elevated callous-unemotional (CU) traits. Conduct problems are among the most prevalent and costly mental health conditions of childhood, and a common antecedent to adult psychiatric disorders. An established risk factor for early, persistent, and severe youth misconduct is the presence of CU traits. CU traits (e.g., lack of empathy or guilt, shallow affect) are analogous to the core affective features of adult psychopathy, interfere with child socialization, and predict poorer outcomes, even with well-established treatments for disruptive behavior disorders. Thus, novel intervention approaches are needed to target CU traits. Youth with elevated CU traits show deficits in facial emotion recognition (FER) for distress-related expressions, particularly fear or sadness. The central hypothesis is that impaired sensitivity for emotional distress cues (fear and/or sadness) is mechanistically linked to CU traits in children, and that, by targeting affect sensitivity directly, intervention can exert downstream effects on CU traits. A gap in the field regards how to remediate these neurocognitive deficits. This project will directly target affect sensitivity in high-CU youth. The investigators propose an experimental therapeutics approach to develop a novel neurocognitive intervention for CU traits, in which a clearly identified target, facial affect sensitivity (FAS), will be engaged and assessed via primary (distress FER accuracy and/or heightened eye gaze) and secondary (electroencephalograph event-related potential) neurocognitive and behavioral processes. If investigators can demonstrate engagement of the target (FAS) in the initial R61 phase, then in the R33 phase, this finding will be replicated with a new, larger sample, and feasibility and preliminary efficacy of FAST on CU traits will be examined. The long-term goal is to examine FAST impact on behavioral outcomes and to potentially apply this targeted intervention to the wider range of problems associated with CU traits. Read Less

This study evaluates the antidepressant effects of an accelerated schedule of theta-burst stimulation, termed accelerated intermittent theta-burst stimulation (aiTBS), in individuals with borderline personality disorder (BPD) or trait and comorbid mood depressive disorder (MDD) or bipolar II disorder in a current mood depressive episode (MDE).

Risk for substance use disorder (SUD) begins early in the life course. Although preventing and decreasing illicit and nonmedical drug use among youth is an urgent public health priority, there are currently few evidence-based prevention strategies feasible for delivery in the primary care setting. The investigators propose a three-year plan to collect critical pilot data to pilot test and optimize a dyadic intervention that aims to increase family resilience, strengthen coping skills, help families plan for the future, and prevent youth SUD. The 'prototype' for the intervention approach is Family Talk, an evidence-based parent-youth dyadic intervention that can be delivered within the existing infrastructure of the patient-centered medical home. The investigators have made preliminary adaptations to the model in preparation for testing. To prepare for a subsequent efficacy study, a two-arm pilot randomized controlled trial of the intervention with 40 parent-youth dyads to optimize the intervention model will be conducted. The feasibility of the intervention will be evaluated. In addition, empiric estimates of study parameters to inform the planning of a fully powered randomized controlled trial and plausible intervention targets using semi-structured qualitative interviews will be obtained.

Investigators will determine whether N-of-1 trials, as a pragmatic, participant-centered approach to medication optimization that can overcome key barriers of deprescribing, can lead to increased participant confidence regarding their preference to continue or discontinue beta-blockers in older adults with Heart Failure with Preserved Ejection Fraction (HFpEF).

The goal of this observational study is to learn about the effects of a specific cystic fibrosis therapy (Cystic Fibrosis Transmembrane Conductance Regulator Modulator Therapy) on chronic sinonasal disease. The main questions it aims to answer are: 1. How does this therapy impact bacterial communities in the paranasal sinuses? 2. How does this therapy impact inflammation in the paranasal sinuses and olfactory cleft? 3. How does this therapy impact sense of smell and sinonasal disease burden in individuals with cystic fibrosis? 4. How does this therapy impact disease-specific and general quality of life of individuals with cystic fibrosis? Participants will be asked to provide samples from their nose, complete testing of their sense of smell, and complete surveys about their quality of life and sense of smell in this study. Researchers will compare study results between patients who are currently undergoing Cystic Fibrosis Transmembrane Conductance Regulator Modulator Therapy and patients who are not currently undergoing therapy.

The researchers are doing this study to find out if a PFME program to reduce urinary incontinence after radical prostatectomy is feasible for people with prostate cancer. The researchers will track how many participants join the study, follow the program, and stay in the study. They will also evaluate how people feel about their experience and satisfaction with participating in this program through interviews. They will also measure participants' quality of life by filling out questionnaires, and we will study whether the program shows promise in reducing urinary incontinence. Radical prostatectomy sometimes causes incontinence after the surgery. The researchers think that by teaching PFME and strengthening and improving control of the pelvic floor muscles, PFME training before and after radical prostatectomy may help reduce incontinence and/or reduce how long incontinence lasts.

The purpose of this study is to learn more about the effects of midodrine and droxidopa, two medications used for the treatment of orthostatic hypotension (low blood pressure on standing), on the veins of the abdomen of patients with autonomic failure. The study will be conducted at Vanderbilt University Medical Center, and consists of 2 parts: a screening and 2 testing days. The total length of the study will be about 5 days. About 34 participants will be screened for the study. Read Less
