Clinical trials

To examine the relations between sleep (nap transitions, sleep physiology), memory, and brain development longitudinally, the researchers will assess n=180 children (in order to acquire n=152 usable data sets) who are 36-54 months of age and habitual nappers at enrollment. In each wave, the researchers will assess memory, memory change over a nap and equivalent waking interval, sleep physiology of the nap, and brain structure and function (using Magnetic Resonance Imagining or MRI). Additionally, overnight sleep physiology will be assessed in all participants. Waves will take place approximately every 6 months. For all children, three waves will be collected. With these data, the researchers will address the following aims: * Examine neural markers that predict the sleep transition (Aim 1); * Examine changes in sleep-dependent memory processing (mnemonic discrimination) over both nap and overnight sleep intervals, across the sleep transition (Aim 2); * Examine changes in sleep microstructure in both nap and overnight sleep across the sleep transition (Aim 3) * Examine interrelations among brain, memory and sleep microstructure across the sleep transition (Aim 4)

The purpose of this study is to evaluate the feasibility and effectiveness of a peer-led, brief, behavioral intervention to improve adherence to medication for opioid use disorder (MOUD) and reduce polysubstance use among patients with OUD and polysubstance use in underserved areas. The intervention is based on behavioral activation (BA) and is specifically designed to be implemented by a trained peer recovery specialist. In this hybrid, Type-1 effectiveness-implementation randomized controlled trial (RCT), the investigators will evaluate the effectiveness and implementation of Peer Activate vs. treatment as usual (TAU) over twelve months.

This is a research study to investigate how influenza transmits from person-to-person. Participation as a healthy "Recipient" in this study involves: * Home semi-quarantine lasting about 14 days during which the participants must wear an N95 in class and take other precautions * Daily assessments and clinic visits for 14 days * Spending every weekday evening for about 14 days from around 6 - 10 pm, including a provided dinner, in a controlled environment. There may be additional sessions and different required participation times on weekends * Exposure to people infected with influenza in the controlled environment * Three blood draws, at the start, at the end of 14 days, and about a month after the end. * A follow-up clinic visits one month after the end of home semi-quarantine * A two-month follow-up phone call. This study may increase the participant's risk of catching influenza. If the participants get infected during the study, the investigators may: * Provide the participants with a prescription for antiviral medication or * Refer the participants for medical care * Ask the participants to become a Donor and expose other Recipients. The participants will be compensated for their time and active participation in the study; however, they may not personally benefit from the study. While the participants may receive supportive care for an infection resulting from the study, this is not meant to replace their regular medical care. If the participants become very ill and need referral for medical care, they or their medical insurance will be billed. If the participants are someone who recently became infected with influenza either through their daily activities or by participating in this study as a Recipient, they are invited to participate in this research study as a Donor and interact with a group of health participants in a controlled environment. Participation in this study as a Donor involves exposing Recipients for at least one and up to five days including: * Attend exposure events in a controlled environment * Weekday evenings from around 6-10 pm * Additional day and evening events on weekends * Events include a provided dinner * Daily assessments and clinic visits for 1 to 5 days * Provide exhaled breath samples for 30 to 60 minutes * Three blood draws, at the start and end of exposure events, and about a month after the end * A follow-up clinic visit one month after their last exposure event * A two-month follow-up phone call If the participants experience severe symptoms related to their influenza infection, we may: * Provide the participants with a prescription for antiviral medication or * Refer the participants for medical care The participants will be compensated for their time and active participation in the study; however, they may not personally benefit from the study. While the participants may receive supportive care for their influenza infection, this is not meant to replace their regular medical care. If the participants become very ill and need referral for medical care, they or their medical insurance will be billed.

The goal of this observational study is to quantify the typical frequency of flatulence in healthy adults, normalized by fiber intake, using the Smart Underwear device. The study will enroll a maximum of 500 adults across the United States who will wear the device for three consecutive days while continuing their usual daily activities. The main questions it aims to answer are: * What is the average frequency of flatus events in a general adult population? * How does dietary fiber intake influence flatus frequency and microbiome activity? Researchers will collect gas sensor data from the Smart Underwear device alongside dietary information logged in a mobile app to assess the relationship between diet and microbiome activity. Participants will: * Complete an online eligibility survey, consent form, and background questionnaire. * Wear the Smart Underwear device for at least 12 hours per day for three consecutive days. * Log all meals with photos using a custom smartphone app. * Complete a short post-wear survey about device comfort and usability. All study procedures will be conducted remotely. Data will be analyzed in de-identified form to evaluate baseline flatulence patterns, normalized to fiber intake, in the general adult population.

The goal of this randomized trial is to test whether the Internet-Delivered Enhanced Assess, Acknowledge, Act (IDEA3) sexual assault resistance education intervention reduces sexual violence victimization in undergraduate women. Participants in the intervention group will be asked to attend four three-hour group sessions of a sexual assault resistance program called IDEA3 with a partner, as well as fill out a number of surveys. Participants in the control group will be asked to attend a one-hour consent workshop with a partner and fill out surveys. Researchers will compare sexual assault victimization between the groups in the one year following the intervention.

Growing evidence demonstrates that secure attachment in childhood predicts children's healthy social, biological, and behavioral functioning, whereas insecure attachment predicts behavior problems and physiological dysregulation; thus, efforts to foster secure attachment are crucial for promoting the healthy development of children and families. This proposal describes a randomized controlled trial (RCT) of an innovative intervention program that can be widely implemented designed to foster children's secure attachment, promote healthy physiological regulation, and reduce the risk for behavior problems: The Circle of Security ® Parenting (COS-P) intervention. To this end, investigators will conduct an RCT with 249 parent-child dyads enrolled or are eligible but not yet enrolled in two diverse Early Head Start (EHS) programs.

Mental health conditions, such as depression, anxiety, and harmful alcohol use are prevalent among people with chronic diseases, including HIV, and contribute to poor engagement in care. There is a need to address untreated mental health problems. Community health workers (CHWs) are frontline workers who play a central role in supporting vulnerable individuals to stay in care, including seeking people living with HIV who are newly initiating antiretroviral therapy (ART) or re-initiating after a period of care disengagement. CHW-delivered interventions are promising for improving engagement and retention in care. Yet, these programs rarely address mental health -a significant barrier to chronic disease care engagement and treatment. An approach that moves beyond providing care in the clinic setting is needed. Community-delivered home-based mental health care has been shown to be feasible and acceptable and shows promise for integration into broader community health care services for people with chronic conditions, such as HIV.

With advancing age, adults experience increasing speech understanding difficulties in challenging situations. Currently, speech-in-noise difficulties are rehabilitated by providing hearing aids. For older normal-hearing adults, however, hearing devices do not provide much benefit since these adults do not have decreased hearing sensitivity. The goal of the "Speech Perception and High Cognitive Demand" project is to evaluate the benefit of a new auditory-cognitive training paradigm. In the present study neural (as measured by pupillometry and magnetoencephalography) and behavioral changes of speech-in-noise perception from pretest to posttest will be examined in older adults (age 65 - 85 years) assigned to one of three training groups: 1) Active Control Group: sessions of watching informational videos, 2) Auditory Training Group: sessions of auditory training listening to one of two speakers in everyday scenarios (e.g., driving directions) and needing to recall what one speaker said in the previous sentence, and 3) Auditory-cognitive training group: identical to the auditory training group, except participants will be asked to remember information from two previous sentences. Changes in speech-in-noise perception will be examined for the three groups of older adults and gains will be compared to a control group of young, normal hearing adults (18-30 years) that is not part of the clinical trial and will not undergo any training.

The proposed research is relevant to public health because stroke is a leading cause of long-term disability among older adults and communication impairments resulting from stroke have a significant negative impact on quality of life. By seeking to better understand post-stroke aphasia, this project lays the groundwork for development of new interventions, and aligns with NIDCD's priority areas 1 (understanding normal function), 2 (understanding diseases), and 3 (improving diagnosis, treatment, and prevention).
