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.
Optical coherence tomography (OCT) is a 3D imaging technology that has seen wide adoption within ophthalmology. However, optical access to the retinal periphery remains a challenge for conventional OCT systems. The study team plans to innovate peripheral retinal OCT imaging technology by first developing the first robotic OCT system capable of autonomously assisting the operator during imaging of the human peripheral retina using 3D active tracking and compensation and then by developing of the first OCT system designed for treatment of the retinal periphery.
While blood clots after major cancer surgery are common and harmful to patients, the medications to decrease blood clot risk are seldom used after patients leave the hospital despite the recommendation of multiple professional medical societies. The reason why these medications are seldom prescribed is not well understood. The main questions this study aims to answer are: - Does surgeon education paired with an electronic medical record based decision support tool improve the guideline concordant prescription of pharmacologic venous thromboembolism after abdominopelvic cancer surgery? - Does dedicated patient education regarding blood clots at the time of hospital discharge after abdominopelvic cancer surgery improve understanding of the risk of venous thromboembolism and adherence to pharmacologic prophylaxis? The investigators will study these questions using a stepped-wedge randomized trial where groups of surgeons will use a tool integrated to the electronic medical record to educate them on the individualized patient risks of blood clots after major cancer surgery and inform them regarding guidelines for preventative medicines. Utilization of the medications before and after using the tool will be compared. Patients will be administered a questionnaire assessing their awareness of blood clots as a risk after cancer surgery. For those prescribed medications to reduce blood clot risk after leaving the hospital, the questionnaire will evaluate whether they took the medications as prescribed. Survey results will be evaluated before and after implementation of education on blood clot risk at the time of hospital discharge.
The investigators hypothesize that single oral high dose supplementation with vitamin A will reduce the incidence of moderate-severe chronic graft-versus-host disease (GVHD) compared with placebo.
This phase II trial tests how well turkey tail mushroom (TTM) works in treating post-menopausal women with HER2-negative, estrogen receptor (ER)-positive breast cancer undergoing surgery. TTM is a common mushroom. In traditional Chinese medicine, it is used for enhancing function and removing toxins, as well as for cancer, hepatitis, and infections. There is previous evidence of significant tumor shrinkage occurring in the 2-month window between diagnosis and surgery in women who have taken TTM. Giving TTM may be effective in treating post-menopausal women with HER2-negative, ER-positive breast cancer undergoing surgery.
In spine surgery, it is important to try to minimize bleeding. In particular, spine surgery often involves inserting hardware into bone, and/or removing bone in the spine. Because the bone in the spine contains blood vessels, there can often be bleeding from the bone itself that is difficult to stop completely. One way to stop bone bleeding is through the use of wax-like materials, which plug the bleeding bone and act as a physical barrier to stop bleeding. One example is Ostene bone hemostasis material, which has the advantage of being "water soluble", meaning it will dissolve naturally over time. The purpose of this study is to evaluate how well Ostene does at decreasing bleeding, by using a recognized scale called the validated intraoperative bleeding severity scale, abbreviated as "VIBe". In this study, the investigators will record the bleeding severity throughout multiple time points in surgery using this scale, and then the investigators will compare the measurements to patients in the past who did not receive Ostene. Overall, this research will help measure how well Ostene decreases bleeding.
The purpose of this study is to assess the efficacy, safety, pharmacokinetics (PK) and pharmacodynamics (PD) of satralizumab, a humanized anti-interleukin-6 receptor (aIL-6R) monoclonal antibody, in ambulatory and non-ambulatory patients with Duchenne muscular dystrophy (DMD) age ≥ 8 to < 16 years old receiving corticosteroid therapy.
The purpose of this study is to determine the effects of high intensity stepping training on gait outcome measures in patients with cerebellar ataxia, to identify the correlations between gait outcome measures and measures of ataxia and balance in individuals with cerebellar ataxia and to determine differences in response to high intensity stepping training based off of diagnosis.
This research study investigates whether male-level exogenous androgens inhibit the reproductive neuroendocrine axis in otherwise healthy (non-PCOS) females.
Tranexamic acid is a synthetic reversible competitive inhibitor to plasminogen lysine receptor, which prevents plasmin formation and stabilizes the fibrin matrix, thus reducing bleeding. While recent studies have demonstrated the antifibrinolytic benefits of TXA in obstetric and gynecologic conditions, traumatic hemorrhage, cardiac surgery, total knee arthroplasty, and more, there is a paucity of clinical data on TXA use in plastic surgery. The aim of this study is to evaluate the effect of local and systemic TXA on postoperative periocular ecchymosis/edema in orbital surgery.
This is a randomised, double-blind, parallel group, placebo-controlled Phase IIa study designed to evaluate the efficacy and safety of AZD7798 in participants with moderate to severe Crohn's disease.
