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.
Through cervical length measurement in uncomplicated twin gestations, women with cervical length ≤ 25 mm will be approached for randomization to cerclage placement or expectant management with activity restriction and treatment of preterm labor
Patients with low-risk or favorable intermediate-risk prostate cancer as defined by 1.2016 NCCN criteria will be eligible to participate on this study.
The aim of this study is to determine if there is a difference in post operative rehabilitation after anterior cruciate ligament (ACL) reconstruction surgery while using moderated blood flow therapy vs. standard physical therapy. All patients undergoing ACL reconstruction, between the ages of 18-30, that consent to taking part in the study, and meet eligibility criteria, will be included in the study. Patients will be followed for two years to determine any differences in muscle strength, thigh circumference, knee range of motion, pain, functional and activity levels, patient satisfaction, levels of Human growth hormone HGH), Insulin-like Growth Factor (IGF), and Creatine Kinase (CK), KT2000, and Lachman physical examination.
Contrast-enhanced ultrasound (CEUS) is a promising non-invasive imaging tool that may aid in the early detection of kidney transplant complications, such as delayed graft function (DGF) and acute allograft rejection. The technique uses an intravenous contrast agent to improve organ visualization with standard duplex ultrasound equipment. A number of FDA-approved agents, including Optison, Definity and Lumason are widely used to improve visualization in technically limited echocardiograms, and Lumason was recently approved for contrast-enhanced ultrasound of the liver. The specific aims of this study are to: develop, implement and refine a contrast-enhanced ultrasound protocol using Lumason to safely maximize kidney allograft visualization; determine associations between contrast-enhanced ultrasound and patterns of allograft injury consistent with delayed graft function; and to compare contrast-enhanced ultrasound with duplex ultrasound for differentiating acute rejection from other causes of dysfunction.
This is a prospective randomized controlled day comparing the efficacy of three-day antimicrobial treatment of asymptomatic bacteriuria (ASB) in pregnancy to the standard seven-day treatment. Half the patients will receive 3-day treatment and the other half will receive 7 days of antibiotics.
This is a prospective imaging study evaluating the utility of baseline metabolic MR imaging with Hyperpolarized Pyruvate (HP) (13C) as a predictive response biomarker to androgen signaling inhibition in patients with castration-resistant prostate cancer.
This is a single arm phase II trial assessing the potential activity of combination PEGPH20 plus Gemcitabine with radiotherapy in ten patients with localized, unresectable pancreatic adenocarcinoma.
This study is a 4-month open-label study of lithium in the acute treatment of patients with bipolar I or II disorder. Eligible patients will receive lithium 300 mg twice daily and titrated in 300 mg increments every 7 days as tolerated to levels > 0.6 mEq/L. Blood samples are collected at baseline and at the end of study. Analyses of 45 molecule expressions in mononuclear blood cells at baseline and endpoint will be carried out after the completion of study. Fifty patients meeting Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) criteria for bipolar I or II will be enrolled.
Obtaining appropriate mydriasis prior to cataract surgery is an important variable in successful surgery. The current practice includes using topical anticholinergic and sympathomimetic agents in the preoperative area prior to cataract surgery, but the pupils are sometimes insufficiently dilated and can often need additional mydriasis with intracameral agents during cataract surgery. Pre-operative topical mydriatic drops take time to take effect, are mildly uncomfortable for the patient, and have a cost to the healthcare system. If intracameral mydriasis alone can achieve adequate pupil dilation, perhaps topical mydriatics would not be needed. The purpose of this study is to evaluate whether topical versus intracameral versus topical + intracameral mydriasis is the optimal way to dilate pupils during routine cataract surgery. The results of this study have implications for improving the efficiency and reducing time prior to cataract surgery. In addition, it has significant potential to reduce the cost associated with cataract surgery if preoperative drops can be eliminated.
The primary objective of this study is to assess the safety and efficacy of Tranexamic acid (TXA) in reducing blood loss and transfusion requirements for patients with osteoporotic hip fractures. In addition to assessing blood loss in these patients, complications associated with TXA use would be characterized including systemic (pulmonary embolism, deep venous thrombosis, myocardial infarction, stroke) and surgical site (hematoma, infection) events, need for re-hospitalization or re-operation and 30 day mortality.
