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 study is to investigate the relationship between arterial carbon dioxide (CO2) concentration and vitreous pressure on the choroidal volume by integrated intraoperative OCT imaging under eye exams under anesthesia.
Individuals with an above-knee lower limb amputation are known to walk more slowly, expend more energy, have a greater risk of falling, and have reduced quality of life compared to individuals without amputation and those with below knee amputation. One of the driving factors behind these deficits is the lack of active function provided by above-knee prostheses with prosthetic knees and ankles. While many prosthetic devices have been developed for functional restoration after major lower extremity amputation, there remains no stable interface to facilitate reliable, long-term volitional control of an advanced robotic limb capable moving multiple joints. Moreover, there is no existing interface that provides useful sensory feedback that in turn enhances the functional capabilities of the prosthesis. To achieve both greater signal specificity and long-term signal stability, we have developed a biologic interface known as the Regenerative Peripheral Nerve Interface (RPNI). An RPNI consists of a peripheral nerve that is implanted into a free muscle graft that would otherwise go unused in the residual limb. As the nerve grows, it reinnervates the free muscle graft which undergoes a predictable sequence of revascularization and regeneration. The main questions it aims to answer are: 1. Can the amplitude, movement specificity and stability of sciatic nerve RPNI electromyography (EMG) signals be detected up to one year post RPNI surgery? 2. Do RPNIs contain information to enable control of a physical motorized prosthetic leg with multiple degrees of freedom? 3. Does stimulation of sciatic nerve RPNIs provides meaningful sensory feedback? Consenting participants with unilateral transfemoral amputation (TFA) will: 1. Undergo RPNI surgery and electrode implantation in the residual limb. 2. Attend regular follow-up visits following surgery to assess the health and signal strength of the RPNIs and their ability to use a prescribed prosthesis between 3- and 12-months following implantation. 3. Undergo explantation of electrodes following the conclusion of data collection.
The goal of this clinical trial is to test a three-item intervention in oral surgeons who remove teeth. The main questions it aims to answer are: - Can the intervention reduce opioid prescriptions to adolescents and young adults after tooth removal? - Do oral surgeons' beliefs about the intervention and opioid prescribing change? - Do patients that report using opioids after tooth removal have different experiences than patients that do not? Oral surgeon participants will: - Attend a 1-hour education session with a trained pharmacist - Receive patient instructions and blister packs of pain medicine to give to patients - Complete 2 surveys about feasibility and appropriateness Patient participants will complete a survey about pain and medication use after having a tooth removed. Researchers will compare the intervention to usual care to see if it reduces opioid prescribing.
The goal of this study is to understand and improve the breast surgical decision-making process for young women newly diagnosed with breast cancer. As part of this study, the investigators will evaluate the impact and use a web-based tool called CONSYDER that is designed to provide useful information to young breast cancer patients. It is also meant to improve communication between young women and their surgeons with the purpose of helping patients make appropriate surgical decisions. Participants will complete surveys within 1 week of the surgical consult and 6 months after surgery. Patients who receive neoadjuvant chemotherapy will also be surveyed after the completion of neoadjuvant treatment but prior to surgery. Some patients will be invited for an interview after their surgery as part of the evaluation. A subset of patients/surgeons will also have their surgical consultation audio-recorded.
Feasibility study investigating the effects of dry needling on individuals with chronic neck pain and sleep disturbance.
Studies across various sports and physical activities have consistently shown that females incur more injuries compared to their male counterparts, but the underlying reasons for this disparity remain poorly understood. While differences in hormone levels between males and females have been speculated to play a role, very little rigorous research has been conducted to directly examine potential connections between sex hormones and injury risk. Specifically, females have been shown to be at greater risk for hand and wrist injuries. The higher injury incidence begins at puberty and persists across the lifespan, suggesting a link to hormonal factors. However, significant gaps remain in understanding the relationships between the menstrual cycle, exogenous hormones from birth control, and risk factors for sports-related injury in females. The purpose of this study is to examine changes in muscle strength and neuromuscular activation among females using monophasic oral contraceptives, females not using oral contraceptives, and males during one week of wrist/hand immobilization.
This study is looking at using a self-contained pH device that will assist in confirming placement of a nasogastric or orogastric tube placed in the stomach of hospitalized infants.
This study is designed to examine the impact of a personalized, body worn alcohol dispenser on the epidemiology of ESKAPE transmission in the anesthesia work area for patients undergoing surgery requiring general anesthesia.
This open-label extension study will evaluate the long-term safety, tolerability and efficacy of orally inhaled seralutinib in subjects who have completed a previous seralutinib study
The investigators are interested in studying the effect of an animated video depicting a nail biopsy procedure on the anxiety, health literacy, and satisfaction of participants recommended to undergo a nail biopsy procedure. The investigators hypothesize that the animated video will reduce preoperative anxiety, increase health literacy, and increase patient satisfaction in relation to nail biopsy procedures.
