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 main objectives of our proposed study are to determine the effects of mango consumption on immune and cognitive functions in free-living college going young adults aged 18-30 years
The purpose of this study is to evaluate the lens vault after implantation of an implantable collamer lens (ICL). The ICL is designed to be implanted in front of the eye, without removing the natural lens. Because of this, it is also known as a phakic IOL. The ICL has already been approved by the U.S. Food and Drug Administration (FDA) to treat mid to high degrees of refractive errors such nearsightedness (also called myopia) with or without astigmatism. Once the artificial lens is implanted, a space between the ICL and the crystalline lens is created, which is called vault.
The goal of this clinical trial is to examine the use of sedative ketamine to treat depression and post-traumatic stress disorder (PTSD) in Veterans with mild to moderate traumatic brain injury (TBI). The main questions it aims to answer are: - Efficacy of ketamine to reduce symptoms of depression and/or PTSD - Safety of ketamine to treat depression and/or PTSD in TBI Participants will be randomly assigned to receive either ketamine or midazolam (active placebo) twice a week for 3 weeks. During participation, subjects will be interviewed, have lab tests, and complete rating scales, and questionnaires.
The purpose of this study is to assess if Num vapocoolant spray decreases pain associated with paracervical block in gynecology procedures.
The goal of this clinical trial is to test a new cognitive training program to improve emotion regulation in adults. The investigators' primary aim is to determine whether participating in this program addresses two key features of emotion dysregulation associated with psychiatric disorders: (1) emotion-related impulsivity and (2) rumination. The investigators will further evaluate participants' perceived acceptability and feasibility of treatment procedures. Secondarily, the investigators will examine the effects of this cognitive training intervention on psychiatric symptoms and overall functioning. Participants will be asked to complete eight weekly sessions (over two months) involving cognitive training exercises with a "coach", in addition to a baseline assessment before starting the intervention and post-treatment assessment. Each assessment includes a combination of in-person and remote data collection using self-report questionnaires, psychophysiology, and a neuropsychological battery. Participants will also complete one week of ecological momentary assessment before and after the intervention as well as a set of follow-up questionnaires administered remotely six weeks following their final training session. Researchers will compare participants randomly assigned to complete the intervention without delay to a control group of participants randomly assigned to a two-month waitlist before joining the intervention. Before beginning cognitive training, participants in the control condition will complete an additional pre-intervention/post-waitlist assessment, which will follow parallel procedures to the initial baseline assessment.
The fundamental aim of this study is to show that the novel contrast agent Gadopiclenol (Elucirem), with its high relaxivity, facilitates increased contrast enhancement and improved differentiation of clinically significant prostate cancer on Prostate MRI, as categorized by the PI-RADS v2 classification categories.
The goal of this clinical trial is to learn more about how the food and nutrition babies receive while in the Neonatal Intensive Care Unit (NICU) influences their ability to gain weight and fat-free mass, and their future growth and development. Participants will: - have body growth measurements collected using the PEAPOD device - have nutritional information collected, and - be followed for neurodevelopmental outcomes Participants can expect to be in the study for 36 months.
The purpose of this study is to test whether a dietary supplement (low-dose melatonin) commonly used to treat night owls, administered in conjunction with a behavioral sleep intervention, will help to shift the brain clock earlier and improve mood and sleep in bipolar disorder. Eligible participants will be randomized to receive melatonin plus a behavioral sleep intervention or placebo plus a behavioral sleep placebo. The hypotheses for this study include: - Melatonin plus behavioral sleep intervention (compared to placebo plus behavioral sleep placebo) will produce a greater advance of dim light melatonin onset (DLMO), between pre- and post-treatment. - Melatonin (compared to placebo) will produce a greater reduction in Patient Health Questionnaire-9 score between pre- and post-treatment.
The purpose of this study is to evaluate an online platform -- the Living Memory Home for Dementia Care Pairs (LMH-4-DCP) for persons with dementia and their family caregivers to engage in reminiscence activities together and record meaningful memories. The main aims of this study are: - To evaluate the feasibility and acceptability of the LMH-4-DCP platform. - To explore the potential for LMH-4-DCP to reduce feelings of pre-loss grief and enhancing relationship quality in dementia family caregivers and their care-recipients ('Care-Pairs') Care pair participants will be asked to log-in to LMH-4-DCP and complete study activities three times per week for one month. Researchers will compare the intervention group to an attention control condition to see if LMH-4-DCP's use is associated with reduced feelings of caregiver pre-loss grief and improved care pair relationship quality at follow-up.
The goal of this study is to see how well therapy with the Eksobionic Exoskeleton (Esko) works for people with Parkinson's disease (PWPD). Esko is a robotic device that provides high repetition and intensity training. The investigators will examine its impact on walking, balance, and quality of life before, during and after an eight-week intervention program. The results will lay the groundwork for future trials, potentially leading to long-term improvements in mobility and quality of life for PWPD.
