44 Clinical Trials for Various Conditions
The goal of this clinical trial in adult patients diagnosed with upper extremity lymphedema is to test the safety and effectiveness of small, wearable sensors that may be able to measure lymphedema. The main questions this study aims to answer are: * Do these sensors detect lymphedema? * If so, how accurate are these wearable sensors? Participants will complete one in-person measurement session and one phone call with study staff 14 days after the measurement session to check-in on the participant's well-being.
This project aims to develop and evaluate a next-generation photon-counting CT prototype, and assess whether next-generation photon-counting CT--which enables reduced radiation dose, high spatial resolution, and spectral imaging--would facilitate improved diagnostic performance for abdominal, cardiothoracic, musculoskeletal, and neuroimaging.
Amniocentesis (amnio) and chorionic villus sampling (CVS) can reliably detect many smaller DNA/genetic abnormalities that cannot be reliably diagnosed by cell-free noninvasive prenatal testing (NIPT) that is in widespread use. The investigators present evidence that a cell-based form of NIPT, here called Single Fetal Cell (SFC) testing, using a blood sample from the mother can detect most or all of the genetic abnormalities that are detected using amnio or CVS. This study proposes to compare the effectiveness of SFC testing in detecting abnormalities already detected by amnio or CVS in women already undergoing these tests as part of their clinical care because of fetal ultrasound abnormalities.
Injuries and disease processes that produce upper extremity deficits are devastating to patients and their families. One potential avenue to treat these neurological disorders is through the enhancement of neural plasticity, which is the ability of the brain to reorganize and recover following insult. After a minor injury, the brain undergoes beneficial neural plasticity, compensating for altered neural activity to restore normal function. However, in the cases of moderate to severe injury and disease, e.g. spinal cord injury (SCI), insufficient or improper plasticity limits recovery, leaving patients with long-term disability. Therefore, methods that can drive robust and specific plasticity have great potential to treat neurological injuries and disease. The Texas Biomedical Device Center (TXBDC) at UT Dallas has developed a groundbreaking therapy, called Targeted Plasticity Therapy (TPT), which pairs traditional motor, sensory, and cognitive rehabilitation with precise stimulation of the vagus nerve, to guide such robust and specific plasticity to treat a wide range of neurological deficits.
The purpose of this study is to develop and demonstrate new technologies that will enable a non-contact, compact eye imaging system based on OCT to assist an early responder in acute care settings (like an emergency room) to help assess eye trauma and inflammation (swelling inside the eye).
The study is designed to collect data from a ultrasound device being used to evaluate feasibility of next generation algorithms for ultrasound data processing and does not test any health outcome.
The goal of this SBIR is to develop and test Assist-MH, a new interactive digital support system for SMH providers. Assist-MH will offer an innovative interactive planning tool to help providers create a treatment plan customized to the student's specific needs. Based on inputs, the system will generate both provider-led MH strategies to optimize time spent with the student and self-paced digital strategies (video, game-based, interactive) for students to augment in-person treatment and provide unique between-session learning and practice. SMH providers will use Assist-MH to plan and assign individualized MH strategies as well as monitor student progress over time (completion and MH functioning).
The purpose of the study is to test an experimental method, a text-messaging app called B-RESILIENT, for improving participants' mood. B-RESILIENT is a text messaging app adaptation of a Resiliency Course, developed by community members known as Building Resiliency and Community Hope.
The goal of Advanced Fetal Imaging - Phase II is to advance fetal MRI imaging by designing MRI coils specifically for pregnant women and testing recently developed MRI image acquisition techniques. The investigators aim to more reliably obtain higher quality fetal MRI images when compared to current clinical fetal MRI.
This study is piloting an internet-based intervention to provide support for caregivers of VA patients with Alzheimer's disease or related memory difficulties (ADRD). Veterans with a clinical diagnosis of ADRD and their caregiver/relatives will be randomized to receive one of two interventions: (1) customary care (cc) and access to an intensive, interactive online education and support website intervention for 6 months, or (2) cc and monthly brief telephone calls with project staff for six month. It is hypothesized that participation in the intensive intervention will result in a reductions in patient problematic behavior and caregiver responses to it, reduced caregiver burden and depression, and improved medication adherence at the end of treatment, and more patients remaining at home through the 12 months post-randomization period..
The purpose of this research is to develop non-invasive imaging modalities for assessment of skin. This is a pilot study which will use multiple imaging modalities to collect information on normal and lesional skin. The researchers understand that the purpose of this study is not to evaluate any particular treatment and an investigation of a new therapeutic intervention would require an additional protocol. Skin conditions to be studied include vascular lesions, pigmentary disorders, inflammatory conditions and neoplasms.
Pressure-related injuries in individuals with SCI and persons who use wheelchairs are one of the most dangerous secondary health problems encountered throughout the lifespan. With recurrence rates as high as 79% and mortality rates as high as 48% when sepsis is present, there exists a critical clinical need to target prevention of pressure injuries. This study will examine the effects of two novel seat mapping technologies ("AW-Shift" and "Sensoria") on increasing in-seat movement in persons who may be at risk for pressure injuries due to altered sensation on their sitting surface. AW-Shift provides a visual display about pressure distribution directly between the body and the seat cushion to a wheelchair user outside of a clinical setting. Sensoria represents a novel technology to promote tissue health by providing users with information about their daily in-seat movement and providing weight shift reminders that are based on time since previous weight shift activities. Changes in the frequency of in-seat movement behaviors will be compared between baseline and each intervention period.
The proposed study will result in a software application compatible with the Apple iPad, iPhone and iPod Touch (hereafter termed "iOS devices") which addresses several aspects of prosodic deficits common in speakers with Autism Spectrum Disorders (ASDs) and other communication disorders, using a developmentally appropriate, intuitive interface that requires little technical skill and which can be managed by educators and parents. The program will contain elements that aid in tracking and maintaining individual student progress records, and will be designed for use in the classroom, at home, and in other environments. This study's intended focus is on the feasibility and usability of the software application.
Cardiovascular disease is the leading cause of death worldwide. Advanced cardiovascular imaging using Magnetic Resonance Imaging (MRI) has proven to be effective in providing gold standard myocardial tissue characterization. Moreover, the intrinsic advantage of MRI's lack of exposure to ionizing radiation is particularly beneficial. At the same time, blood work can be very useful in early detection of certain cardiomyopathy, such as amyloid. However, there is a lack of agreement of on which markers are the most sensitive. This multi-study will allow us the unique opportunity to form a more comprehensive understanding for various cardiovascular diseases. Our team has developed novel cardiac MRI techniques that leverages endogenous tissue properties to reveal a milieu of deep tissue phenotypes including myocardial inflammation, fibrosis, metabolism, and microstructural defects. Among these phenotypes, myocardial microstructure has proven to be most sensitive to early myocardial tissue damage and is predictive of myocardial regeneration. In this study, the investigators aim to further study the importance of cardiac microstructure revealed by MRI in patient and healthy population and compare this novel technology with conventional clinical biomarkers.
This study is being done to help researchers learn more about and successfully diagnose cancer using blood samples and tissue samples from surgeries in patients with suspicious thyroid nodules or thyroid cancer. Diagnosing cancer in this way, as opposed to biopsies, may be less invasive to the patient. Analyzing blood and tissues samples may also help researchers to differentiate non-cancerous tumors from thyroid cancer and detect high-risk mutations to guide treatment.
The investigators will link community pharmacy and primary care practices via a shared electronic health record to improve medication therapy management for older patients taking complex prescription (Rx) regimens. The Technology-Enabled Alliance for Medication Therapy Management (TEAM) intervention will link a major, national community pharmacy chain (Walgreens) to primary care practices (Access Community Health Network) via a shared electronic health record (EHR) platform (Epic, Verona WI). Through shared access to patients' medical records, pharmacists can perform comprehensive medication therapy management services, document and communicate patients' Rx challenges for review and action by primary care providers. The aims of this investigation are to: 1. Evaluate the fidelity and efficacy of the TEAM intervention to promote healthcare provider counseling, medication reconciliation, and safe regimen use among adults taking complex Rx regimens. 2. Explore patient, healthcare provider (pharmacist, prescriber), community pharmacy and/or primary care practice barriers to implementation. 3. Determine the costs of the TEAM intervention from both a community pharmacy and primary care practice perspective.
Clinical trials will evaluate the efficacy of expert guiding technology to support instructors to better help individuals with developmental challenges due to ASD and ID learn life and vocational skills. Single Case Research Designs (SCRD) will be used to evaluate expert guiding technology interventions to support Task Analysis. SCRDs are a viable alternative to large group studies such as randomized clinical trials. Single case studies involve repeated measures, and manipulation of an independent variable. SCRD studies allow for rigorous experimental evaluation of intervention effects and provide a strong basis for establishing causal inferences. Research design: A multiple baseline across tasks or participants will be used to evaluate the impact of the expert guiding technology on staff and consumers' performance. Dependent Variables. DV1: Staff performance: The percentage of teaching steps correctly implemented will be calculated and monitored. The teaching steps are predetermined including what types of prompts will be used for each step of the task analysis of the identified consumer's adaptive living skills, record data on consumer's performance, and the timing of delivery of reinforcers and prompts. DV2: Consumers' performance: The percentage of Independent completion of the steps of task analyses for identified daily living skills will be calculated and monitored. The completed step is considered "independent" when the consumer completed the step without prompts from the staff within five seconds of the initial instruction (discriminative stimulus) given or the completion of the previous step. DV3: Consumers' performance: the amount of time taken to independent completion. Independent Variable: Versions of expert guiding technology to support instructors in providing Task Analyses instruction while collecting data on consumer performance. GAINS: During the GAINS sessions, the staff will follow the pre-programmed teaching protocol in the expert guiding technology. The system will provide step-by-step verbal prompts to the staff throughout the sessions. This includes which prompt to use for each step, when to provide reinforcers, and which target task to work on. The system will also monitor the consumer's progress and notify the staff if the target task is mastered or not.
Individuals at high-risk of suicide vary substantially from one another. Over time, risk factors for suicide may change within the same individual. Despite these differences, most treatments for suicidal thoughts assume that the same intervention works equally well for all individuals at high-risk of suicide. Intensive longitudinal data combined with network science, integrated with coaching, could be used to personalize suicide prevention interventions to make them more effective and efficient. This K23 Career Development application involves refining and testing a novel personalized treatment for individuals at high-risk called PeRsonalizEd Clinical Intervention for Suicidal Events or PRECISE. PRECISE leverages idiographic statistical techniques adopted from network science applied to ecological momentary assessment data to inform the tailoring of Safety Planning and skills from Dialectical Behavior Therapy, two existing evidence-based treatments for suicide. In Aim 1, a user-centered design approach will be used to refine PRECISE. Following the refinement of the intervention, informed by data from a case series in Aim 1, the investigators will then conduct a randomized controlled trial comparing two different intensities of personalization. In the low-intensity arm, the 8-week treatment will be tailored based on an initial two-week burst of ecological momentary assessment and one idiographic model. In the high-intensity arm, participants complete eight weeks of ecological momentary assessment and idiographic models are generated between each session. Coaches use the idiographic models to identify an individuals' drivers of suicidal thoughts and conduct behavioral chain analyses to tailor specific skills to then teach, shape, and reinforce in their individual clients. Assessments are completed pre-treatment, 8-weeks post-enrollment, and 16-weeks enrollment. The investigators hypothesize that both arms will demonstrate clinically significant reductions in suicidal ideation, but the high-intensity arm will be superior to the low-intensity arm in reducing ideation. Furthermore, the investigators anticipate that increases in effective emotion regulation skills and reductions in negative affect will account for the decrease in suicidal ideation. As individuals learn more effective emotion regulation strategies, they will experience less distress and thereby lower levels of suicidal ideation. This project is responsive to Objective 3.2 of the NIMH Strategic Plan and is integrated with a mentored research training plan focused on 1) suicide specific rigorous clinical trials, 2) user centered design in digital health, and 3) applications of network science to intensive longitudinal data. The project and training goal will support the Candidate's overarching goal to become a clinician-scientist engaged in independent research on personalized, impactful, rapid acting suicide prevention interventions for at risk adults.
The focus of the current study is to systematically investigate the psychometric properties of a range of aided language measures, which are based on the Graphic Symbol Utterance and Sentence Development Framework (Binger \& Kent-Walsh).
The overall aim of this study is to test the acceptability and usability of a mobile application (app) for family-based physical activity and weight gain prevention among parent/guardian and child (ages 9-12 years) dyads.
Maternal sensitivity and contingent responsiveness to infant behavioral cues is an important contributor to infants' developing capacities to self-regulate. During early infancy, feeding interactions comprise a significant portion of mother-infant dyadic interactions and high-quality feeding interactions provide both nutritive and socioemotional benefits; recent data suggest that, for many dyads, mothers' sensitive responsiveness during feeding interactions is routinely impacted by the omnipresence of portable technology. The objective of the proposed research is to better understand the development and possible impacts of maternal technology use on infant feeding interactions, emotion and intake regulation, and sociobehavioral and growth outcomes.
The goal of this research study is to provide an avatar-based technology during a subject's stay for participants who have been admitted to the hospital for reduced-intensity conditioning (RIC) allogeneic transplant. The intervention received will be the care.coach technology.
The goal of this work is to address increasing concerns about young children's digital media exposure and language outcomes by testing how the times course of word learning unfolds in digital environments and the cascading impact of digital media on vocabulary outcomes. The findings will have important implications for understanding when and where optimal word learning from media can occur.
The AIDI study has to phases. It's purpose is to capture vital signs using a non-invasive, hand-held, home monitoring device (MouthLab Device) from individuals with COVID-19 or who test positive for SARS-CoV-2 (Phase I) and use an algorithm-based approach to identify individuals at risk of clinical decompensation (Phase II). Up to 500 unvaccinated and partially vaccinated subjects will be included (up to 100 in Phase I and up to 400 in Phase II).

The purpose of this proposed study, is the development and validation of EISA, a Self-report outcome measurement tool, for assessing the satisfaction of everyday functional needs, for consumers using Electronic Assistive Devices (EADs) as the primary means to complete Instrumental Activities of Daily Living (IADLs). The EISA outcome measure is proposed to be designed as a questionnaire that can be self or interview-administered to users of EADs. The development of EISA shall be modeled along the lines of development of the self-report outcome measure, Functional Mobility Assessment (FMA) (Kumar et al., 2013). The proposed tool EISA, would serve as a dynamic gage, for assessing perceived user function, related to using EADs for completing IADLs. The instrument is proposed to undergo systematic development in three phases. In phase 1, an initial pool of potential EISA items shall be generated, based on literature review data. In phase 2, content experts (clinician and EADs user) review panels, shall assess the initial pool of potential EISA items for further content validity. The objective of phase 3, would be a validation of the first iteration of EISA, by establishing reliability for test-retest administration and internal consistency, at acceptable levels, by 25-100 EADs users. Statistical analysis for test-retest reliability and internal consistency estimation shall be carried out in phase 3 of the study, using Statistical Package for the Social Sciences (SPSS) version 24 software.
After development of the Talk Stem Familia (TSF) smart-speaker application prototype, the study will evaluate the prototype's efficacy in a within-subjects pre-post design study. The sample will contain 50 parent-student/child dyads who will use the Alexa skill app for 6 weeks.
Background: Magnetic resonance imaging (MRI) is an important non-invasive tool to study and diagnose cardiovascular disease. MRI scanners use strong magnetic fields and radio waves to create pictures of body organs. Researchers want to find better MRI methods and new ways of imaging cardiovascular disease and better understand normal and abnormal cardiovascular and brain function. Researchers are also interested in seeing if gadolinium, the commonly used MRI contrast agent, stays in the body long after the MRI was performed. Objectives: To develop new methods for imaging the heart and other organs of the body. To describe cardiovascular diseases using newer MRI methods To look at the relationship between cardiovascular disease and cardiovascular risk factors and other organ systems To look for gadolinium deposits in the brain from prior exams. Eligibility: Healthy people and people with known or suspected cardiovascular disease ages 7 and older may be eligible for this study. Researchers may be particularly interested in those who: * Have suspected or known cardiovascular disease * Were previously exposed to a gadolinium-based contrast agent, * Need to have a heart MRI scheduled * Need a test of the heart or other body part or will be undergoing a future cardiac catheterization Design: There are multiple arms to the study with optional components; therefore, there are multiple variations as to what an individual participant s experience may involve. Participants will have an MRI scan lasting up to 2 hours. The scanner is a large hollow tube. During the scan, there may be loud knocking and buzzing sounds caused by the scanner. Participants will lie on a table that slides in and out of the tube. Their vital signs may be monitored. Participants may have a test of heart electrical activity using wires connected to pads on the skin. Participants may have blood drawn. Participants may be injected with an MRI contrast agent through a plastic tube inserted in the arm.
