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.
Background: SARS-CoV-2 is the virus that causes COVID. It has caused a global pandemic. Most people have no to mild symptoms. But some people need to be hospitalized, and a small number need critical care. Older age as well as some socio-demographic factors and chronic health conditions may play a role in the severity of COVID. In this study, researchers want to assess sociodemographic-, population-, disease-, and gene-based risks for features associated with severe SARS-CoV-2 outcomes. As more is understood about COVID, researchers also want to learn more about people s experiences with COVID vaccines, long-haul symptoms, and other related disease features. Objective: To measure the frequency and severity of COVID infection in people with rare and common diseases, looking for conditions that increase risk of severe outcomes. To describe experiences with COVID vaccines, symptoms, and other features of COVID in people with rare and common diseases. Eligibility: People greater than 1 month of age, both with and without rare disease, who have access to the Internet. Design: This study will take place online. Participants will visit a website. They will fill out a survey. It should take less than 30 minutes to complete. They will answer questions about their current health and COVID experiences. They will answer questions about their demographic and location features that may impact their exposure to the virus. All questions are optional. Participants may repeat the survey if their responses indicate a need for follow-up. Participants medical records may be reviewed. Participants may be contacted for future studies related to: COVID Their underlying health conditions A new exposure that is being studied....
Intimate partner violence (IPV), including violence in teen dating relationships [teen dating violence (TDV)], is a common and a serious threat to adolescent health, safety, and well-being. TDV may include psychological/emotional abuse, sexual harassment or coercion, stalking (including cyberstalking), and physical or sexual violence. For many, the first experience of violence is in a dating or casual relationship with a partner or acquaintance during adolescence. Therefore, the objective of this study is to examine the effectiveness of an adapted version of the myPlan app for adolescents (ages 15-17 years) to prevent and respond to TDV. myPlan is an app available for mobile download or by web browser that interactively assists users to assess the health and safety of user's intimate relationship, receive personalized strategies on how build healthier relationships, stay safe and healthy while navigating an unsafe relationship, and get connected to support and resources.
HIV disproportionately affects Latinos who have more infections, faster disease progression, more HIV-related deaths, and slower diagnosis and treatment than their white/majority counterparts. This is a concern across the United States (US) and in developing countries, such as the Dominican Republic (DR). The HIV-related health disparities experienced by Latinos are made worse when those living with HIV have low health literacy and difficulty understanding the information they need to manage their health. The PI developed a set of images to assist clinicians in providing information to Latino people living with HIV (PLWH). These images have been put into a mobile health app so clinicians can easily access them during clinic visits. The PI has tested her with PLWH in the DR and in New York City. So, the next steps in this research are to ensure the images are relevant and useful to Latinos across the United States (US) and to further assess if, and to what extent, the images can improve health outcomes among PLWH in the US and in the DR. We will therefore, adapt images to Latinos of Mexican origin/descent and then test them to determine if these images help clinicians provide information to patients by conducting a study at clinical sites in the US and in the DR.
Use of crystal methamphetamine (MA) leads to changes in sexual risk behavior, adherence to HIV prevention tools, immune response to infection, and tissue inflammation that collectively increase risk for HIV transmission among MA-using men who have sex with men (MSM), their sexual partners, and their networks. Contingency Management (CM) offers a behavioral modification tool helpful for reducing frequency of MA use, but the effects of CM on the behavioral and biological factors that promote HIV transmission in MSM networks have only been partially evaluated. The intersection of substance use, sexual risk behavior, and HIV transmission in MSM networks presents a critical problem for contemporary HIV prevention as HIV-uninfected MSM who use MA have a 16%-33% greater risk for HIV infection, while only approximately 50% of HIV-infected MA-using MSM achieve and maintain an undetectable viral load. The investigators propose to compare two different CM models to integrate substance use treatment with HIV prevention among MA-using MSM: 1) Traditional CM targeted to MA abstinence and 2) Allternative CM based on ARV adherence.
This is a multi-center, sample collection study to follow clinically suspicious lesions to determine the outcome including surgical biopsy, removal, monitoring, etc. for up to 2 years after lesion identification. Subjects who had, or will have a DermTech Pigmented Lesion Assay completed on a lesion suspected of being melanoma are eligible for the study. Based on historical data, an expected melanoma rate of approximately 5% to 10% is anticipated.
This study will aim to evaluate the effect of therapeutic and supratherapeutic oral doses of GSK3640254 on cardiac conduction compared to placebo and a single oral dose of Moxifloxacin in healthy adult participants. The study has 2 parts: Part 1 will determine the supratherapeutic dose for Part 2, which will be the main corrected QT interval (QTc) study. Part 1 will evaluate once daily (QD) dosing of GSK3640254 or placebo and Part 2 will investigate the safety, tolerability and Pharmacokinetics (PK) of GSK3640254 doses on cardiac conduction as compared to placebo and a single oral dose of Moxifloxacin in healthy adult participants. Moxifloxacin will be included as a positive control.

The Infinitome Program from Omniscient has the ability to identify abnormal brain networks or connectomes using resting state functional MRI (rs-fMRI). This technology, which visualizes brain networks in three dimensions, was originally developed to ensure neurosurgeons avoid inadvertently lesioning cognitively eloquent brain regions during surgical operations. The potential of Infinitome in identifying connectome dysfunction for neurodegenerative diseases such as Alzheimer's disease has yet to be explored. This diagnostic technique may play a critical role for identifying disease brain networks that may benefit from targeted interventions in clinical trials.
The investigators have developed a portable, battery-operated, mobile high-resolution microendoscope (mHRME) that provides subcellular images of the anal epithelium, delineating the cellular and morphologic changes associated with neoplasia. The investigators' central hypothesis is that this 'optical' approach will increase the efficiency, clinical impact, and cost-effectiveness of the current standard of high-resolution anoscopy(HRA)-guided biopsy, thus facilitating usage by less-experienced clinicians in community-based or low-resource settings. To validate this, the investigators will conduct a study to determine the efficiency and diagnostic characteristics of the mHRME 'optical biopsy' approach versus the current standard of HRA-based tissue biopsy. Successful results will allow for improved efficacy and resource utilization for cancer screening in people living with HIV for anal cancer and other epithelial cancers including the cervix, oral cavity, bladder, and GI tract.
VXA-CoV2-1 is a non-replicating Ad5 vector adjuvanted oral tableted vaccine being developed to prevent COVID-19, the disease resulting from Severe Acute Respiratory Syndrome coronavirus (SARS-CoV-2) infection. The study is designed to evaluate the safety and immunogenicity of VXA-CoV2-1 vaccine with repeat dosing at multiple dose levels. Safety and immunogenicity will be evaluated for up to 12 months after the second dose of VXA-CoV2-1.
