There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This project aims to enroll 220 incarcerated individuals living with HIV, Hepatitis C (HCV), or history of substance misuse preparing for release into a pilot implementation study to test the feasibility and acceptability of an adapted Coordinated Transitional Care intervention in a Criminal Justice setting (CJC-TraC). Participants can expect to be on study for up to 6 months.
The vast majority of all trauma-related amputations in the United States involve the upper limbs. Approximately half of those individuals who receive a upper extremity myoelectric prosthesis eventually abandon use of the system, primarily because of their limited functionality. Thus, there continues to be a need for a significant improvement in prosthetic control strategies. The objective of this bioengineering research program is to develop and clinically evaluate a prototype prosthetic control system that uses imaging to sense residual muscle activity, rather than electromyography. This novel approach can better distinguish between different functional compartments in the forearm muscles, and provide robust control signals that are proportional to muscle activity. This improved sensing strategy has the potential to significantly improve functionality of upper extremity prostheses, and provide dexterous intuitive control that is a significant improvement over current state of the art noninvasive control methods. This interdisciplinary project brings together investigators at George Mason University, commercial partners at Infinite Biomedical Technologies as well as clinicians at MedStar National Rehabilitation Hospital. The investigators will optimize and implement algorithms for real-time classification and control with multiple degrees of freedom (DOF) using a miniaturized ultrasound system incorporated into a prosthetic socket. The investigators will then compare control performance between and sonomyography and myoelectric control (both direct control and pattern recognition) using a virtual environment as well as for performance of tasks related to activities of daily living. The investigators have two specific aims. Specific Aim 1: Compare between sonomyography and myoelectric direct control Specific Aim 2: Compare between sonomyography and pattern recognition with velocity control The successful completion of this project will lead to the first in human evaluation of an integrated prototype that uses low-power portable imaging sensors and real-time image analysis to sense residual muscle activity for prosthetic control. In the long term, the investigators anticipate that the improvements in functionality and intuitiveness of control will increase acceptance by amputees.
Emerging adults (ages 18-25) are at higher risk for substance use disorders, including opiate addiction, than any other age group but are also more likely to drop out early from substance use treatment services. This project will evaluate an enhancement to usual services, delivered by peer recovery supports, specifically aimed at improving treatment adherence and reducing dropout in this age group. The study will also answer key questions about risk factors for dropout among emerging adults and the financial sustainability of enhancing services to reduce dropout.
This study examines whether use of a commercially-available vaginal wellness system is able to establish a microbiome in transgender women.
This is an observational study evaluating patients diagnosed with narcolepsy or idiopathic hypersomnia that have been prescribed a new/different hypersomnia treatment. The study is being done to better understand how hypersomnia treatment(s) impact blood pressure and cognitive function.
Public deliberation is a novel method for engaging the public in collective decision-making. Its goal is to facilitate debate and discussion that: 1) fosters the formation of reasonable and informed opinions, 2) permits participants to revise their perspectives and positions in light of new information and dialogue with others, and 3) encourages participants to consider not only their own preferences but also the greater goal of a policy or resolution that is justifiable for all persons affected by the issue under debate. Public deliberation involves: in-depth education on the topic of interest, presentation of conflicting perspectives from expert witnesses and key stakeholders, facilitated public discussion of core issues, and development of resolutions that are acceptable to participants. Public deliberation requires significant commitment from deliberants who are actively engaged over the course of several sessions. Public deliberation can be successful when more traditional methods of stakeholder engagement fail, as it allows for in-depth discussion and demonstrated awareness of the moral difference in deciding for oneself and others. Minor consent to biomedical HIV prevention research highlights difficulties with consent, particularly for minors, and how key ethical principles may come into conflict. Typically, institutions and investigators rely upon parental permission to protect minors from research-related harm and coercion. However, the parent permission model may be harmful in stigmatizing health research such as HIV. The consent process creates potential for disclosure of the minor's sensitive behaviors and/or identities to their parents who were otherwise unaware of them. This risk is heightened for sexual and gender minority adolescents, who may face physical and social harm when their sexual or gender identities are disclosed. This risk of harm, and the ethical conflict it creates has contributed to delays in clinical trials and clinical use of HIV prevention methods in minors. This project will test public deliberation as a method for improving consent processes for engaging individuals from marginalized communities in clinical research on sensitive or stigmatizing health problems. The investigators use minor consent for biomedical HIV prevention research as an exemplar case. The primary hypothesis is that public deliberation will produce a resolution to ethical conflicts in minor consent that is better or different from the results of more traditional study approaches (e.g. surveys, in depth interviews).
Background: COVID-19 affected African Americans more than Whites. African Americans, especially women, have had higher rates of COVID-19 infections compared to Whites. They are also more likely to go to the hospital or die of this disease. Many researchers who looked into these issues lacked background data on the people they studied. SELF is a 10-year study of fibroids in African American women aged 23-35. Researchers already have a lot of data on these women. Asking how COVID-19 affected them can add context other studies lack. Objective: To describe the impact of the COVID-19 pandemic on young African American women and their families. Eligibility: Participants must be enrolled in SELF (Study of Environment, Lifestyle, and Fibroids). Design: Researchers will invite all women enrolled in SELF to participate in this natural history study. Participants will complete one questionnaire. They will answer the questions online. They may also choose to get a paper copy sent by mail. The survey will take no more than 15-20 minutes. All questions will relate to COVID-19. Participants will be asked if they had COVID-19. They will be asked if family, friends, or members of their community did. They will answer questions about their vaccine status and access to health care services. Participants will also answer questions about how the pandemic affected their lives. They will be asked about their job and if finding childcare was a challenge. They will be asked about money problems and how they coped. They will be asked about sleep problems and emotional distress. Participants will get a $30 gift card after they finish the survey.
This study seeks to understand the relationship between prenatal maternal air pollution exposure and offspring risk for ADHD and examine two potential -modifiable- mechanisms: prenatal maternal inflammation and offspring sleep problems. We will employ a longitudinal neuroimaging study design and leverage a well-characterized intergenerational cohort of Puerto Ricans to address prior literature's limitations. This will be the first study to use infant neuroimaging to disassociate the effects of prenatal pollution exposure from those of postnatal pollution exposure, adversity and disadvantage, and offspring genetic risk for ADHD.
The purpose of the study is to test whether low level electric stimulation, called transcranial Direct Current Stimulation (tDCS), on the part of the brain (i.e., pre-supplementary motor area) thought to aid in memory will improve speech and language difficulties in patients with primary progressive aphasia (PPA) and progressive apraxia of speech (PAOS). The primary outcome measures are neuropsychological assessments of speech and language functions, and the secondary measures are neuropsychological assessments of other cognitive abilities and electroencephalography (EEG) measures.
Cleidocranial Dysplasia (CCD) is a rare, autosomal dominant disorder characterized by dysplasia of bones and teeth. Given the rarity of this condition (prevalence of 1 in 1,000,000), the variable phenotype and lack of correlation to specific genotypes, coordinated clinical research is needed to better understand CCD. The purpose of this project is to: investigate the genetic makeup and phenotypic expression of CCD, understand the quality of life for patients with this diagnosis, and further identify the multidimensional healthcare needs of these patients. Participation involves completion of a survey to ascertain medical history and quality of life, a physical exam and research whole exome sequencing from a blood or saliva sample. The goal of this research is to elucidate critical pathways in skeletal and dental development and improve quality of life for CCD patients through the standardization and optimization of timely diagnosis and multidisciplinary care.
