The overall goal of the proposed research is to evaluate the use of \[11C\]SY08 as a PET radiotracer for aggregated alpha synuclein (αS) in individuals with Parkinson's disease (PD), Multiple system atrophy (MSA), Dementia with Lewy Bodies (DLB) and healthy controls. The purpose of this study is to evaluate the use of \[11C\]SY08 as a PET radiotracer for αS fibrils in individuals with PD, MSA, DLB and healthy controls. The specific aims of the current study are: 1. To determine brain uptake, distribution, and kinetics of \[11C\]SY08 in healthy individuals. 2. To determine brain uptake, distribution, and kinetics of \[11C\]SY08 in patients with alpha synuclein aggregates in the brain, including PD, DLB and MSA. 3. To determine human dosimetry of \[11C\]SY08 in healthy individuals An intravenous bolus injection of \[11C\]SY08 will be administered per subject for brain PET imaging. Read Less

The objective of this project is to create richer tactile aids by using materials chemistry to create tactile sensations in tactile aids, as an alternative to traditional physical bumps, lines, or textures. These materials are commonly used in household products, but have not yet been used to enrich tactile aids. Successful outcomes are primarily the accuracy with which low vision or blind subjects identify objects made from tactile coatings versus traditional tactile aids. Other outcomes include time to completion of the task, or the number of distinctive categories that participants can identify. Read Less

The primary aim of the project is to test the efficacy of BCBT delivered via a digital platform (i.e., smartphone) to Servicemembers with recent suicidal ideation and/or suicide attempts presenting to primary care clinics. Given existing challenges of scaling empirically-supported treatments/interventions for suicidality with fidelity, this project could lead to markedly expanded access to BCBT, along with improving our understanding about what intervention strategies are most effective and how they can be delivered with meaningful fidelity. Aviva, the digital version of BCBT, was developed for use with patients across the full spectrum of healthcare settings, including primary care. Aviva is not an emergency alert system, rather a digital platform for delivery of the full scope of BCBT treatment components. An open-label single group Phase I clinical trial has demonstrated the safety, tolerability, feasibility, fidelity, and potential efficacy of Aviva, with participants completing modules over 8 weeks, and follow-up assessments at weeks 1, 4, and 8. Subsequent refinements included the addition of technical features that would allow patients to revisit and/or repeat previously completed modules, along with integration of more characters for delivering video vignettes and greater opportunities for skills practice and treatment engagement. These modifications have further enhanced Aviva safety, tolerability, and fidelity, consistent with the original BCBT protocol. Not only is it hypothesized that Aviva will result in significantly larger reductions in severity of suicidal ideation than participants randomized to the control condition, but also that greater app engagement will be negatively correlated with severity of suicidal thinking. Moderators and mediators (i.e. suicidal beliefs, wish to live, impulsive decision-making) of intervention effects will also be examined. The study will be conducted at the primary care clinics at Fort Carson, with a goal of enrolling 720 patients across a two-year timeframe. Participants will be identified using each clinic's existing suicide risk assessment methods, including the PHQ-9 suicide risk item and a score of 1 or higher on the CSSRS Screener (Recent). Participants will be randomly assigned to one of two treatment conditions, Aviva or control (i.e., development of a safety plan consistent with local procedures and policies, along with referral for standard mental health care and suicide risk management in accordance with local policies and procedures). In an effort to address potential performance bias specific to smartphone use, participants in the control condition will download the Suicide Safety Plan app to their smartphones. Those in the Aviva condition will also complete weekly check-ins with Project 2 research clinicians to review treatment adherence, identify and respond to any logistical/operational problems, and respond to any unexpected emergencies and/or participant safety concerns. Participants will have up to five data points: baseline, 3, 6, 9, and 12 months. All data available from all participants and all time points will be included in the analyses, consistent with the intent-to-treat principle. Across our two previous clinical trials and our in-progress RCT, attrition during the first 12 months postbaseline was \<30% and we anticipate similar rates in this trial. Read Less

Comorbid Childhood Apraxia of Speech (CAS) may be one factor that limits speech development in some minimally verbal children with autism. CAS is a disorder affecting speech movement planning. This study tests whether CAS-specific treatment, appropriately modified for minimally verbal children with autism, improves their speech. Read Less

Nearly one in five children are obese, and disparities in overweight and obesity between children from low- and middle-to-high-income households persist despite a multitude of school-based interventions. The structured days hypothesis posits that structure within a school day plays a protective role for children against obesogenic behaviors, and, ultimately, prevents the occurrence of excessive weight gain, thus, past school-based efforts are misplaced. This study will provide access to healthy structured programming via vouchers to afterschool programs and summer day camps during two "windows of vulnerability" (ie afterschool and summer) for low-income children.

Studies show that virtually all increases in children's (5-12yrs) BMI occur during the summer, no matter children's' weight status (i.e., normal weight, overweight, or obese) at summer entry. Recent preliminary studies show that children engage in healthier behaviors on days that they attend summer day camps, and that BMI gain does not accelerate for these children. The proposed randomized dose-response study will identify the dose-response relationship between amount of summer programming and summer BMI gain. Read Less

This phase II trial investigates how well modified VR-CAP (bortezomib, rituximab, cyclophosphamide, doxorubicin hydrochloride, prednisone, and cytarabine hydrochloride) and acalabrutinib as first line therapy work in treating transplant-eligible patients with mantle cell lymphoma. Modified VR-CAP is a combination of drugs used as standard first line treatment for mantle cell lymphoma. Chemotherapy drugs, such as bortezomib, cyclophosphamide, doxorubicin hydrochloride, and cytarabine hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Rituximab is a monoclonal antibody that binds and depletes malignant B cells, by inducing immune responses and direct toxicity. Acalabrutinib blocks a key enzyme which is needed for malignant cell growth in mantle cell lymphoma. Combining modified VR-CAP and acalabrutinib as first line therapy may be more useful against mantle cell lymphoma compared to the usual treatment. Read Less
