All Clinical Trials

The purpose of this study is to research if a type of biopsy known as sentinel lymph node biopsy (SLNB) can help in determining the rate of tumor deposits that are hard to detect and identify in node-negative cutaneous squamous cell carcinoma of the head or neck. Read Less

The goal of this clinical trial is to compare the effect of language and behavioral interventions for students who are English language learners and who have symptoms of attention-deficit/hyperactivity disorder (ADHD). The main question it aims to answer is: - Which intervention is better for the students: the behavioral intervention, the language intervention, or a combination of the behavioral and language interventions? Participants will be asked to do the following: * Participants' parents and teachers will be asked to complete questionnaires about their behavior. * Participants will be asked to complete tests assessing language, cognitive, and academic abilities. * Members of the research team will complete classroom observations for the participating students. * Participants will be randomly assigned to one of four groups: a school as usual group, a language group, a daily report card group, and a combined daily report card and language group. * If assigned to the language group, participants will receive an 18-week language intervention. * If assigned to the daily report card group, a behavioral consultant will work with participants' parents and teachers to set up a home-school behavior plan called a daily report card. * If assigned to the combined daily report card and language group, participants will receive both the language intervention and the daily report card. * If assigned to the school as usual group, participants will no study interventions. Researchers will compare the language group, the daily report card group, the combined language and daily report card group, and the school as usual group to see which group has the best language learning and classroom behavior at the end of the program.

The goal of this clinical trial is to test effects of the Great Life Mentoring (GLM) program on the mental health and adaptive functioning on school-age youth (ages 9-16) from low-income families who are receiving outpatient mental health services. The main questions it aims to answer are: • Does participation in the GLM program improve mental health and related outcomes among school-age youth (9- to 16-years-old) from low-income families as an adjunct to outpatient mental health services? 180 youth will be enrolled in the study and assigned randomly to either continue mental health services as usual (SAU) or to continue mental health services while also participating in GLM (SAU+GLM). Participating youth, and their parent/guardians and therapists, will be surveyed annually. Mental health services records also will be obtained with appropriate permissions. . Researchers will compare the SAU and SAU+GLM groups to see if participation in GLM has an effect on the mental health and related outcomes of study youth. Read Less

The overarching aim of the proposed work is to align a promising treatment lead - Musical Intervention (MI) - with a promising mechanistic account of psychosis - Predictive Processing. This protocol focuses on the R33 phase, to optimize its administration (Is active participation more effective than passive listening? Does creation of new music help more than performing others' creations?). By tracking the interrelation between symptom mechanisms and MI, the investigators can use those metrics to prospectively assign patients to particular MI. The R33 phase will examine the impact of SING on computational behavioral metrics of (Aim 1) Conditioned Hallucinations, (Aim 2) Social Reinforcement Learning, (Aim 3) Language Use, in 200 participants with voice hearing in the context of a psychotic illness (n=50per per group). Following a screening visit to determine eligibility, these computerized tasks will be administered behaviorally, and an interview will elicit speech, prior to and following the full SING intervention (in 10 groups of 5 participants, each facilitated by a trained musical interventionist, during the first two years of the project). Participants will complete these tasks prior to and following randomization to four different conditions (facilitated by a SING team member) that will deconstruct the possible active ingredients of SING along two dimensions: Activity and Ownership: (a) SING (n=50, Activity + and Ownership +), participants produce and perform their own song; (b) Karaoke (n=50, Activity + and Ownership -), participants perform karaoke, singing along to others music; (c) Pop Music (n=50, Activity - and Ownership -), participants will listen to popular music chosen by the music interventionists; and (d) Curated Playlists (n=50, Activity -, Ownership +), participants will curate playlists of popular music and listen to them together. This deconstruction will provide insights into the predictive processing framework, as applied to hallucinations and music, specifically, whether changes at higher, a-modal, hierarchical levels, particularly sense of self and active inference, influence precision weighted perceptual and social inferences more so than inactive experiences or experiences that do not engage sense of self. This R33 portion of the study was originally included in NCT05537428, which now has results posted for the R61 phase of the study. Read Less

Premature infants commonly have desaturation episodes due to different reasons such as cessation of breathing or loss of lung volume. The purpose of this study is to differentiate the mechanisms of desaturation episodes with continuous lung volume monitoring. As we better understand the mechanisms underlying the desaturation episodes, newer strategies directed at underlying pathophysiology can potentially by evaluated for mitigation of these episodes.

Study aims to examine the effects of noninvasive brain stimulation on brain signals. This insight may have potential clinical implications for addiction, pain, and mental health populations. Participants will receive MRI and CT imaging. Participants receive low-intensity focused ultrasound (LIFU) to temporarily change brain activity. Participants then receive fMRI scans to measure changes in both resting and heat evoked brain signaling using a quantitative sensory testing device. Heart rate, blood pressure, respiratory rate, and skin moisture is monitored. Participants complete a battery of questionnaires, both behavioral and symptom monitoring. The study takes place over 4 study visits. Read Less
