Dexmedetomidine (Dex), a selective α2-adrenergic receptor agonist, is the most used sedative for procedural sedation in children and in pediatric Intensive Care Unit (PICU) because it is associated with less respiratory depression and also less neurotoxicity; rather Dex appears neuroprotective. Unfortunately, Dex is associated with very long emergence times and may cause bradycardia and hypotension. However, using sedation dosing guidelines (by consensus among SPS members) 1-3 mcg/kg bolus and a 1-2 mcg/kg/hour infusion, hemodynamic compromise is less significant and rarely requires intervention in these patients. With this Dex sedation protocol, these pediatric patients usually take an average of 45 minutes (30-60 minutes) to wake and become alert and up to 2 hours to be discharged. Without reversal agents, emergence times from Dex sedation are slow. The prolonged recovery after Dex sedation for non-surgical procedures negatively affects throughput, thus increasing the cost of care. Patient safety and satisfaction suffer as a result. The children wake feeling tired and sluggish. The children don't feel back to normal for an extended period of time, which is not surprising given that the half-life for Dex metabolism in 2-3 hours in humans. However, using sedation dosing guidelines (by consensus among SPS members) 1-3 mcg/kg bolus and a 1-2 mcg/kg/hour infusion, hemodynamic compromise is less significant and rarely requires intervention in these patients. In humans, it has been found that caffeine at 7.5 mg/kg (15 mg caffeine citrate equivalent to 7.5 mg caffeine base) sped emergence from isoflurane anesthesia with minimal hemodynamic effects in healthy human volunteers. The goal of this clinical trial is to determine whether caffeine will facilitate the recovery of Dex sedation after a Magnetic Resonance Imaging (MRI) procedure by measuring the time from the end of Dex infusion to the time meeting the discharge criteria.

Age:3 - 12

100 Participants Needed

Caffeine is one of the most widely consumed substances worldwide. This study looks to test and measure the changes in different biomarkers in the blood before and after having caffeine using capillary and venous blood sampling methods. A biomarker is a measurable indicator of biological processes. The primary goal of this clinical trial is to evaluate participant rate and adherence. It will also learn about how caffeine affects different biomarkers that may be related to cardiovascular disease. Finally, it will assess the accuracy of the capillary blood samples compared to the venous blood samples. The main questions it aims to answer are: * What is the feasibility of recruiting and retaining participants? * Are the study procedures appropriate to be translated to a larger future study? Researchers will compare caffeine to a placebo (a look-alike substance that contains no drug) to see if Participants will: * Be randomly assigned to the control group or the caffeine group. Individuals in the control group will be taking a placebo pill with no effect and those in the caffeine group will be taking 400mg of caffeine in pill form. * Be asked to undergo a fast of at least 8 hours overnight before taking two placebo pills or the 400 mg of caffeine via two caffeine pills. They will be required to stay fasted for 6 hours after taking the pill as well. The total time fasted will be at least 14 hours. * Have blood collected using three different methods before taking the two pills, 3 hours after taking the pills and 6 hours after taking the pills. The 3 methods include intravenous (IV) blood sampling, finger prick and collection on Whatman 903 Protein Saver Card and collection using the TASSO+ device. The TASSO+ blood collection device is a small capillary blood collection device that is designed to be easy to use and able to be used outside of a hospital/lab setting. Whatman 903 Protein Saver Cards are special filter paper with five circles for samples, that are designed for the collection and storage of blood.

Factors Affecting Oxygen Toxicity

Durham, North Carolina
The goal of this clinical trial is to learn about the mechanisms of oxygen toxicity in scuba divers. The main questions it aims to answer are: * How does the training of respiratory muscles affect oxygen toxicity? * How do environmental factors, such as sleep deprivation, the ingestion of commonly utilized medications, and chronic exposure to carbon dioxide, impact the risk of oxygen toxicity? * How does immersion in water affect the development of oxygen toxicity? Participants will be asked to do the following: * Undergo a basic screening exam composed of health history, vital signs, and some respiratory function tests * Train their respiratory muscles at regular intervals * Exercise on a cycle ergometer both in dry conditions and underwater/under pressure in the context of medication, sleep deprivation, or carbon dioxide exposure Researchers will compare the performance of each subject before and after the possible interventions described above to see if there are changes in exercise performance, respiratory function, cerebral blood flow, and levels of gene expression.

Caffeine for Learning in Healthy Adults

Charlestown, Massachusetts
This research study aims to determine whether and how caffeine intake affects learning process through reward feedback compared to placebo. The data acquired from this study would improve our understanding on the consequence and mechanism of caffeine intake in the aspect of learning process. Participants will perform a reinforcement learning task (i.e. Probabilistic Selection Task) and a motor inhibition task (i.e. Go/NoGo task) in a brain scan. The scan will be done with the Siemens Biograph mMR positron emission tomography (PET)/ magnetic resonance imaging (MRI) 3 Tesla scanner. The PET allows us to see the changes in the "reward signals" - dopamine - in the brain using a radioactive dye called \[11C\]Raclopride. The MRI, on the other hand, enables us to take detailed pictures of the brain activities during cognitive tasks using a high-powered magnet. Reviewing these pictures will help us understand the influence of caffeine on reward signals and brain activities during the learning process.

This clinical trial will be a comparison between personalized recommended caffeine dosing regimen versus the standard recommended caffeine dosing regimen for sustaining performance during sleep deprivation and minimizing side effects and subsequent sleep disruption. The questions this study aims to answer are: Whether the personalized caffeine recommendations improve vigilance, sleepiness, and cognition after total sleep deprivation, compared to standard recommendations; Whether the personalized caffeine recommendation better addresses the physical and emotional side effects of total sleep deprivation, compared to standard recommendations; And whether personalized caffeine recommendations aids in better recovery sleep after total sleep deprivation, compared to standard recommendations. Participants will be asked to: 1. Complete a 13-day at-home portion, wearing an actigraph watch to measure activity and sleep, and complete motor vigilance tests up to six times a day. 2. Complete a 4-day in-lab portion, where participants will have to complete one night of baseline sleep, undergo 62-hours of total sleep deprivation, and then complete one night of recovery sleep. 3. During the in-lab portion of the study, participants will be asked to complete more motor vigilance tests. Researchers will be comparing the personalized caffeine recommendation group against the standard caffeine recommendation to see if it is better at addressing each of the main questions.

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

Frequently Asked Questions

How much do clinical trials pay?
Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.
How do clinical trials work?
After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length is 12 months.
How do I participate in a study as a "healthy volunteer"?
Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.
What does the "phase" of a clinical trial mean?
The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.
Do I need to be insured to participate in a medical study ?
Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.
What are the newest clinical trials ?
Most recently, we added Caffeine for Sedation Recovery in Children, Caffeine for Newborn Brain Injury and Caffeine for Cardiovascular Disease to the Power online platform.
