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 clinical trial will compare how many days per year people with lower limb prosthesis do not wear their prosthesis when fitted with a conventional liner and a liner made with phase change materials.
Background: Many people suffer from drug addiction. But currently, treatments are not very effective. One group of patients in this study are enrolled in addiction treatment through physician health programs (PHPs). About 70% of these patients are able to stop using drugs for extended periods of time. By studying this specific group of patients, researchers want to understand the difference between those who may or may not respond to treatment. They want to study the brain while people do thinking and feeling tasks and when they relax. They will study brain chemicals, a stress hormone, and certain genes. The results may help them understand the brain basis for addiction and recovery. Objectives: To use brain imaging to find differences between people with and without drug addiction. To see if these differences help predict addiction. Eligibility: Healthy, right-handed adults ages 21-65, enrolled in a physician health program or those with no history of addiction and with at least 16 years of education Design: Participants enrolled in a PHP will be screened under this study and participants with no history of addiction will be screened under another study. At the study visit, participants will: Have a routine check-up, including tests for pregnancy, drugs, and alcohol. Give 11 blood samples. Rate their cravings. Test their frustration with stressful situations by responding to questions on a screen. Practice the magnetic resonance imaging (MRI) tasks: Shock task. Two electrodes placed on a foot will deliver brief, low-strength electrical shocks that get gradually stronger, but not painful. Participants will see drug or neutral images. They will rate their discomfort. Thinking tasks. Participants will answer questions about pictures, numbers, and money. They will press buttons in response to things they see. Do the MRI tasks in 2 sessions (morning and afternoon) in the scanner. Participants will lie in an MRI machine which will take pictures of the brain while doing these tasks. Some participants will repeat the visit twice over a year at set intervals. Meals will be provided, and visits will include meal breaks and smoking breaks for those who smoke.
The main purpose of this study is to evaluate whether exposure to ice chips in the mouth (oral ice chips) during oxaliplatin treatment prevents or reduces symptoms of cold sensitivity.
This study will evaluate the safety and efficacy of relamorelin compared to placebo in participants with diabetic gastroparesis. Participants will report daily severity scores of their diabetic gastroparesis symptoms.
To combat post-transplant weight gain, we seek to expand Stanford Kidney Transplant's multidisciplinary platform to include physical activity monitoring and coaching using the Apple Watch.
The United States (US) faces a crisis of pain management. According to the 2012 National Health Interview Survey, almost 50 million adults in the US reported having significant chronic or severe pain (Nahin 2015). Doctors in the US still prescribe opioids across the board for pain despite a growing recognition of an epidemic of opioid overdose and use disorder. Few solutions have been successfully proposed and implemented. Placebos represent a novel and potentially fruitful means of addressing this issue. However, clinicians often use placebos deceptively and with little rationale or evidence of benefit, making their use ethically problematic. In contrast with their typical current use, a provocative line of research suggests that placebos can be intentionally exploited to extend analgesic therapeutic effects. Recently, we reviewed a database of placebo studies including 22 studies in both animals and humans hinting of evidence that placebos may work as a dose extender of active painkillers. Placebos given after repeated administration of active treatments can acquire medication-like effects based on learning mechanisms. Here, we will test if dose-extending placebos are effective in relieving clinical acute pain in opioid patients with traumatic pain. Patients will be randomized to three arms. Arm 1 will be a Full Dose (FD) group, which will receive all NSAIDs as described in the Guidelines for NSAID use in Orthopedic Patients and Oxycodone (5mg). Arm 2 will be a Partial Reinforcement (PR) group, which will receive NSAIDs, Oxycodone (5mg), and placebos to reach a 50% reduction of the total intake of opioids. Finally, Arm 3 will be a Control (C) group receiving NSAIDs and placebos. Patients will be assigned to one of three arms according to a 1:1:1 schedule of randomization. Study IDs will be generated by the pharmacy and blinding will occur by ensuring that oxycodone and placebos look, smell, and taste identical. Rescue therapy will be provided as needed. This novel prospect of placebo use has the potential to change our general thinking about painkiller treatments, the typical regimens of painkiller applications, and the ways in which treatments are evaluated.
The purpose of this study is to see if Tranexamic Acid can safely reduce bleeding in people undergoing spinal fusion surgery.
This randomized pilot phase I trial studies the side effects and best dose of anti-SEMA4D monoclonal antibody VX15/2503 when given together with nivolumab or ipilimumab in treating patients with stage III or IV melanoma. Monoclonal antibodies, such as anti-SEMA4D monoclonal antibody VX15/2503, nivolumab, and ipilimumab, may interfere with the ability of tumor cells to grow and spread.
A multi-center randomized controlled clinical trial to evaluate Autonomic Regulation Therapy with the VITARIA system in patients with symptomatic heart failure and reduced ejection fraction.
Surgery wounds are typically closed with combination of absorbable stitches placed under the skin and non-absorbable stitched placed at the skin surface. Absorbable sutures can produce unwanted side effects when the body produces a reaction to them. The investigators are conducting a study to determine if absorbable stitches can be replaced but tissue glue applied on the surface of the skin. If participants enroll in the study, the investigators will close one half of the participants wound with absorbable stitches placed under the skin and non-absorbable stitches on the surface. The other half of the wound will be closed with non-absorbable stitches and tissue glue. The appearance of the scar (if any) will then be evaluated at 3- and 6-month follow-ups by two dermatologists (either board-certified dermatologists or dermatology residents) and the patient.
