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 is a prospective, multi-center, randomized effectiveness trial of the CardioGard Embolic Protection Cannula in high-risk valve surgery patients.
The goal of this clinical trial is to test Epitel's™ Remote EEG Monitoring System's (REMI™) ability to record electroencephalography (EEG) of seizure events in an ambulatory setting for extended periods (14 - 28 days) in patients presenting with questionable seizure characterization. The main questions it aims to answer are: • Can more seizure events be recorded in fourteen (14) days than can be recorded in three (3) days? • Do treating clinicians find clinical value in extended fourteen (14) - twenty-eight (28) days of EEG? Participants will wear a portable EEG device (REMI) for fourteen (14) to twenty-eight (28) days in their home/community setting.
Nicotine remains a major cause of health problems in the US and around the world. Insight into the behavioral changes induced by nicotine use may help advance the understanding of the mechanisms underlying the maintenance of nicotine addiction and thus the important factors involved in the quitting process. Pavlovian bias is a phenomenon that includes an approach tendency toward rewarding cues and an action withdrawal tendency in response to punishments. This phenomenon may be particularly relevant to nicotine users. The current study will use an experimental, within-subjects, repeated-measured design to investigate whether acute nicotine administration influences individual Pavlovian bias in nicotine users. By recruiting participants from the University of Southern California (USC) community and contacting participants of previous nicotine-related studies of the Addiction and Self-Control Laboratory at USC, the investigators will enroll forty adult nicotine users in the study. Participants will come to the lab twice after a 10-hour nicotine fast. At each lab visit, participants will undergo a vaping session prior to completing the study tasks. The content of the e-liquid in the vape will vary by nicotine content: the vape will either contain nicotine or not. Subsequent to vaping, participants will complete a version of the Go/No-Go task which will measure their individual levels of Pavlovian bias. The investigators will compare performance on the task across the two conditions within each participant: on- and off- nicotine, after controlling for nicotine withdrawal and nicotine tolerance. Based on past research on nicotine, the researchers anticipate that acute nicotine administration will be associated with higher levels of Pavlovian bias, compared to the off-nicotine condition. Specifically, two patterns are expected to arise: a higher likelihood of making a go-response in the "win reward" condition and a higher likelihood of making a no-go response in the "avoid losing" condition, regardless of whether it is a "go" or "no-go" trial. Participants will also complete a measure of their working memory capacity. The investigators will conduct exploratory analyses for the relationship between different nicotine conditions and working memory capacity.
The goal of this clinical trial is to see if shorter Photodynamic Therapy (PDT) treatment times will still be effective at treating actinic keratoses (AK) while reducing or eliminating the pain that patients sometimes experience during conventional PDT treatment. The main questions it aims to answer are: - Will the application of the nanoemulsion (10% ALA gel), in the absence of occlusion, still achieve significant inflammation and lesion clearance? - Will shortened incubation times of Ameluz still achieve significant inflammation and lesion clearance? - Will the new test regimens achieve reduced pain during illumination? - Will the new test regimens be safe? Participants will be randomly assigned to one of three treatment regimens, which will determine the length of time that the topical medication will incubate on the face before red light exposure in PDT treatments. The incubation period will be either 10 minutes, 20 minutes, or 60 minutes.
The main goal of this study is to use automated electronic reports to assess and improve guideline-concordant antibiotic use for: 1) adult inpatients with community-acquired pneumonia (CAP); 2) pediatric inpatients with CAP; 3) adult outpatients with acute pharyngitis; and 4) pediatric outpatients with acute otitis media. There are two cohorts in this study: Patients with one of the aforementioned conditions who meet inclusion criteria, and the clinicians providing clinical care to these patients.
The purpose of this study is to determine the impact of the SPIO® Core-MAX® Expedition orthosis on an infant's head, trunk and upper limb function.
The goal of this clinical trial is to test the effects of MitoQ supplementation in older adults and frail older adults with physical dysfunction and/or cognitive dysfunction. The main question[s] it aims to answer are: - To compare vascular function, oxidative stress levels, and physical and cognitive function among older adults and frail older adults with physical and cognitive dysfunction - To determine whether MitoQ supplementation has the potential to improve vascular function in central and cerebral vessels - To determine whether MitoQ supplementation can enhance physical and cognitive capabilities.
The goal of this research study is to investigate the feasibility of implementing a prehabilitation program that aims to improve a patient's physical, nutritional, and sleep health before surgery in an older, at-risk group with esophageal cancer.
The purpose of this study is to assess the relative biological availability and the effect of food on the drug levels of Danicamtiv in health adults.
The goal of this clinical trial is to test a cell phone-based online program that provides Alzheimer's risk assessments and memory tests over a 6-month period. The main question it aims to answer is whether online software can help reduce the risk of Alzheimer's disease (AD) through digital education and tracking. Participants will visit RetainYourBrain.com to answer questions about their risk factors for AD and take online word recall and card game cognitive tests. Researchers will track progress over time and compare different strategies of Alzheimer's education to see if it is possible to protect brain health, reduce Alzheimer's risk, and improve memory function.
