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.
The benefits of adolescent vaccines are well known for preventing meningococcal infection and human papillomavirus (HPV)-related pre-cancerous lesions. Yet, many adolescents in the United States (US) remain under-vaccinated, with vaccination rates among rural adolescents significantly lower than among their urban peers. In addition, there are urban-rural disparities in the coverage of HPV vaccine, particularly in Southern states like North and South Carolina, which currently fall below the Healthy People 2020 goal of ≥80% coverage. The goal of the proposed study is to evaluate the feasibility and preliminary efficacy of a school-based intervention for increasing vaccine uptake among adolescents in rural North and South Carolina.
The purposes of this study are to demonstrate the non-inferiority (NI) of the neutralizing antibody response to the original strain 14 days after booster vaccination with Ad26.COV2.S at the different dose levels, administered greater than or equal to (>=) 6 months after single-dose primary vaccination with Ad26.COV2.S, compared to the neutralizing antibody response to the original strain induced by single-dose primary vaccination with Ad26.COV2.S; To demonstrate the NI of the neutralizing antibody response to the leading variant of high consequence or concern 14 days after booster vaccination with Ad26.COV2.S at the 5*10^10 virus particle (vp) dose level, administered >= 6 months after single-dose primary vaccination with Ad26.COV2.S (5*10^10 vp dose level), compared to the neutralizing antibody response to the leading variant of high consequence or concern induced by single-dose primary vaccination with Ad26.COV2.S at the 5*10^10 vp dose level, if feasible; To demonstrate the NI of the neutralizing antibody response to the original strain 14 days after booster vaccination with Ad26.COV2.S at the different dose levels administered >=6 months after completing a 2-dose primary vaccination with Pfizer BNT162b2, compared to the neutralizing antibody response to the original strain induced by 2-dose primary vaccination with Pfizer BNT162b2; To demonstrate the NI of neutralizing antibody response to the leading variant of high consequence or concern 14 days after booster vaccination with Ad26.COV2.S at the 5*10^10 vp dose level, administered >= 6 months after completing a 2-dose primary vaccination with Pfizer BNT162b2, compared to the neutralizing antibody response to the leading variant of high consequence or concern induced by 2-dose primary vaccination with Pfizer BNT162b2, if feasible.
Myeloma is the second most common type of blood cancer in the United States. Myeloma most commonly affects older adults. While some younger individuals do get myeloma, the average age when people are first diagnosed with myeloma is around 69 to 70. Along with having a higher risk for myeloma, older adults have an increased chance of developing other health problems or issues. However, not everyone ages in the same way. Some older adults experience major changes in health or degree of independence at relatively younger ages, while others remain quite healthy for many years. The specific issues that develop with age can also vary from person to person. One older adult may face difficulties with vision or hearing, while another may develop memory problems. Historically, cancer doctors have not done a very good job identifying these non-cancer issues. As a result, research has focused on better ways to systematically pick up on issues that may impact cancer outcomes or quality of life. The outgrowth of this research is assessments and questionnaires referred to as "comprehensive geriatric assessments," which evaluate the health and functionality of older adults thoroughly but efficiently. In both myeloma and other types of cancer, problems identified through geriatric assessments have been shown to predict how likely people are to develop side effects of cancer treatment and predict how long people are likely to live with cancer. Prior research has not addressed how best to help with the issues picked up through a geriatric assessment among patients undergoing treatment for myeloma, although a number of effective interventions have been shown to benefit older adults with similar problems in other settings. Therefore, the current study will test a strategy of systematically screening older adults undergoing myeloma treatment for geriatric-assessment-related deficits and referring participants to appropriate services and resources. The geriatric assessment in this study includes tests of mobility, memory, vision, hearing, and nutrition as well as questions about symptoms and social support. Individuals who have deficits in one of these areas will be referred to relevant services and resources such as physical therapy, a pharmacist, or the cancer center support program. They will then repeat the same assessment three months later, and the results will be compared to their original assessment to see if the deficit has improved, with particular attention to mobility and social support.
Purpose: To investigate the short-term clinical effect of curcumin-containing toothpaste on halitosis as compared to placebo and to assess potential shifts in the composition of dental biofilm associated with the use of curcumin-containing toothpaste Participants: This clinical study will 30 adult participants under prophylactic or periodontal maintenance protocol. Procedures (methods): Participants will be included and throughout the protocol will not allow the use any other oral hygiene products except standard manual toothbrush and study toothpaste (either test -curcumin-containing or placebo). Additionally participants will be instructed to odiferous foods such as onions, garlic and spices. At each of the three examination sessions, Plaque Index (six sites, O'Leary) and volatile sulphur compounds (VSC) will be measured.
The main purpose of this study is to estimate how much LY3471851 gets into the blood stream and how long it takes the body to remove it when administered under the skin in healthy participants. The study will also evaluate the safety and tolerability of LY3471851. The study is expected to last up to 87 days for each participant.
Participants who have met all protocol eligibility criteria will be randomly assigned to treatment (ARO-APOC3 or placebo) in a double-blind fashion and will be evaluted for safety and efficacy over 48 weeks. Participants will be counseled to remain on a specified diet throughout the study, as recommended by the Investigator in accordance with local standard of care. After week 48, participants will be eligible and invited to consent and continue in an open-label extension study. All placebo participants who opt to continue will switch to active drug (ARO-APOC3) during the extension study.
Adolescent's poor sleep habits have been linked to adverse outcomes. Recent advances in activity tracking have provided researchers with cost-effective and non-invasive measurements of sleep in a free-living environment. The primary objective is to determine the mean differences in Fitbit accelerometer sleep quantity (mins) between High School student-athletes and non-athletes during a competitive academic semester over continuous monitoring for two weeks.
The primary objective of the present protocol is to evaluate the effectiveness of real HBMT versus placebo on reducing HAB and aggression. The secondary objectives of the present protocol are: 1. Investigate the role of individual difference variables on HAB, interpersonal aggression, and effects of HBMT. 2. Collect vocal recording data to inform the development of algorithms to predict emotional stress from changes in speech.
The purpose of this exploratory cross-sectional investigation is to evaluate associations between tap water perceptions, water consumption behaviors, and hydration status in Latinx adults (18 - 65 y). The objective is to identify perceptual determinants that explain the associations between tap water avoidance and plain water intake and hydration status in Latinx adults. Aim 1: Characterize the degree to which individual- and community-level factors uniquely predict the perception that tap water is not safe in Latinx adults. Aim 2: Evaluate household income, education level, and US nativity as potential moderators of the associations between predictors and perceptions of tap water safety. Aim 3: Evaluate the influence of tap water safety perceptions on plain water intake and 24-h hydration status, after adjustment for predictors of tap water safety perceptions, in a sub-sample of Latinx adults.
The study is a randomized crossover trial. Current menthol smokers will complete a session with each flavor of an electronic cigarette: menthol and tobacco. The objective of this survey is to assess for flavor preference.
