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.
Adenomyosis affects approximately 21% of symptomatic women who present to gynecology clinics. The disease is characterized by heavy bleeding and pain during periods. Limited treatment options exist for the treatment of adenomyosis for women who desire future child-bearing or prefer to avoid surgery. Recently, ulipristal acetate has been studied as a treatment option for women who have fibroids and heavy bleeding. The majority of women treated with ulipristal stopped having periods altogether. Our study aims to determine whether ulipristal is an adequate treatment for women with adenomyosis.
The KEO study is a single arm phase II trial including 44 patients with T1N1-2B, T2N0-N2B head and neck squamous cell carcinoma (HNSCC) eligible for curative-intent resection (+/- adjuvant therapy), who receive neo-adjvuant pembrolizumab + epacadostat. The primary objective of this study is to determine rate of major treatment effect (MTE) to neoadjuvant pembrolizumab+epacostat immunotherapy in SCCHN compared to historic data with neoadjuvant pembrolizumab alone.
The purpose of this study is to assess the safety and efficacy of using Restylane Silk to reduce the appearance of photoaging on the chest. Restylane Silk is a temporary hyaluronic acid filler currently approved for the lips and fine lines around the mouth. This study will compare the appearance of chest wrinkles on half the chest treated with Restylane Silk and the other half, which will be treated with placebo.
The primary objective is to identify which patients undergoing a traditional pterional approach with 2 different surgical techniques for TMS (Temporal Muscle Suspension) will develop TH (Temporal Hollowing. Pre and post-operative CT scans will be reviewed and analysis with previously proven metrics will be performed.
Coronary artery computed tomographic angiography (CTA) is a widely used, highly accurate technique for the detection of coronary artery disease (CAD), with sensitivity and negative predictive values of over 90% (1-4). Patients with normal CTA findings have an excellent prognosis and do not require further testing for CAD (5). However, like invasive coronary angiography (QCA), CTA is an anatomic test and, unless lesions are very severe (>90% stenosis), cannot reliably predict the impairment of flow (functional significance) of intermediate grade stenoses. For this reason, in approximately 15-25% of patients, additional functional testing may be required after CTA, usually in the form of stress testing (6-8). Stress testing is commonly done by exercise or pharmacologic stress with electrocardiographic monitoring and often, imaging of myocardial perfusion by nuclear scintigraphy (MPI) or detection of abnormal contraction by echocardiography. This requires a separate procedure, entailing time, expense and limited risk. Furthermore, in patients with previously known CAD, CTA alone is not an adequate test, because in most cases there are multiple lesions that are possible sources of ischemia. Over the last 10 years, these investigators and others around the world have developed a method of imaging myocardial perfusion by CT (CTP). This test is an adjunct to the usual Cardiac Computed Tomography Angiography (CCTA) procedure and can be done immediately thereafter, using conventional pharmacologic stress agents. It has demonstrated accuracy in many single center trials, and in this large multicenter study, the CORE320 trial (9,10) which showed a high accuracy in predicting the combined results of QCA plus MPI testing and a second multicenter trial established non-inferiority of myocardial CTP compared with nuclear stress testing (11,12). Additionally, this investigator group has published a direct comparison of diagnostic performance of myocardial CTP imaging and SPECT myocardial perfusion imaging and demonstrated superior diagnostic performance of CTP imaging compared with SPECT for the diagnosis of significant disease on invasive angiography (13). CTP images can be acquired with two different approaches: static or dynamic. In the CORE320 study, the CTP protocol used static acquisition method. The static CTP method, samples a snapshot of the iodine distribution in the blood pool and the myocardium over a short period of time, targeting either the upslope or the peak of contrast bolus. The notion behind this is that, at the upslope of the contrast, the difference in attenuation value of the ischemic and remote myocardium is at the maximum which enables for qualitative and semi-quantitative assessment of myocardial perfusion defects. The static CTP, however, does not allow for direct quantification of the myocardial blood flow (MBF). One of the drawbacks of static CTP lies in the acquirement of only one sample of data and the possibility of mistiming of the contrast bolus that results in poor contrast-to-tissue ratios by missing the peak attenuation (14). Output and flow rate of the contrast material may affect bolus timing. In addition, the acquisition of data from sequential heartbeats affects the attenuation gradient and may result in a heterogeneous iodine distribution, mimicking perfusion defects (15). Furthermore, the static CTP is limited in detection of balanced ischemia, where the perfusion of the entire myocardium is impaired and therefore there is no reference remote myocardium for comparison for semi-quantitative or qualitative static methods of CTP interpretation. Dynamic CT perfusion imaging uses serial imaging over time to record the kinetics of iodinated contrast in the arterial blood pool and myocardium. This technique allows for multiple sampling of the myocardium and the blood pool and creating time attenuation curves (TAC) by measuring the change in CT attenuation over time. Mathematical modelling of TACs permits for direct quantification of MBF. Despite its advantages, the use of dynamic CTP were limited in the past. A high temporal resolution and high number of detectors are required for dynamic CTP to allow for entire myocardial coverage, and in order to obtain multiple consecutive images at high heart rates(16,17). But the main challenge of dynamic CTP acquisition was the high radiation dose associated with this technique. Nevertheless, with the introduction of the cutting-edge 320 detector CT scanning systems with fast gantry rotation the issue of the cardiac coverage is eliminated(17). The second-generation 320-row scanners also permit the quantification of the MBF with dynamic CTP acquisition with relatively low-dose of radiation(18,19). In this study the investigators aim to evaluate the feasibility, safety and accuracy of the low-radiation dose dynamic myocardial CT perfusion compared to static CTP approach to detect hemodynamically significant coronary artery disease.
The objective of this study is to determine if inpatient COPD education would result in improved patient knowledge of COPD.
Conventionally fractionated radiation therapy given over 6-7 weeks alone, sequentially, or concurrent with chemotherapy have produced poor outcomes in Stage II NSCLC in most series. Stereotactic ablative radiotherapy (SABR) has been shown to be very effective and is now standard of care for Stage 1 disease. There has been initially reluctance to utilize SABR for central lung tumors because of published reports that showed an excess of toxicity when SABR was utilized; however, newer data with less intense treatment regimens suggest safety in treatment of central lung disease. The safety and efficacy of SABR in treating hilar nodes or N1 disease currently is not known fully and will be evaluated in this study.
This is a protocol to obtain pilot data to submit a new NIH grant on Nocturnal Hypertension and Nocturia. In the diversity supplement to Dr. Victor's current NIH grant (Cut Your Pressure Too: The Los Angeles Barbershop Blood Pressure Study) the results show that uncontrolled systolic hypertension is an independent determinant of nocturia in African American men. the investigators now want to pursue this correlation by designing a new NIH grant proposal to determine whether replacing short acting with long acting drugs and dosing them at bedtime rather than in the morning will: A. Lower systolic blood pressure during sleep B. Improve nocturia and result in better sleep quality
Sixty patients will be identified in the clinic with rotator cuff tendonitis or a low-grade partial-thickness tear of the rotator cuff that are either insulin-dependent or insulin-independent diabetics. Patients will be informed about the current prospective study and written consent will be obtained. Patient information about kidney function, current diabetic medication type, dose and frequency will be obtained in clinic. If there is a diagnosed kidney function abnormality, the patient will be excluded from the study. Patients will be asked about their most recent HbA1C. If HbA1C has not been checked within the past 3 months, the patient will have HbA1C checked in the lab either same day as the injection or the following day. Patients will be randomized into two patient groups: Toradol (Ketorolac) injection group (n=30) and or Steroid injection group (n=30). The randomization will be done using an online randomization tool: http://www.graphpad.com/quickcalcs/index.cfm. Patients assigned to Toradol group will receive 60mg of Toradol (Ketorolac) mixed with 8mL of 1% lidocaine with epinephrine 1:100,000. Those assigned to Steroid group will receive 80mg of Kenalog (Triamcinolone Acetonide) mixed with 8mL of 1% lidocaine with epinephrine 1:100,000. Patients will be blinded to the kind of injection they receive, but the physicians who perform the injection will not be blinded for the medical record purposes. The injection will be done under ultrasound guidance to the subacromial space. Continuous blood glucose measurement will be started in an hour within the injection. An instructional session about continuous glucose monitoring will be given to the patients by our research team immediately following the injection. The blood glucose levels will be monitored for 1 week following the injection. The data will be collected on the patient's return to clinic in 2 weeks. Pain score based on a visual analog scale will be obtained prior to injection, 5 min, 3 days, 1 week, 2 weeks, 4 weeks, 6 weeks, 8 weeks, and 12 weeks after injection. Shoulder range of motion, patient satisfaction, QuickDash score, and ASES survey score will be measured in clinic 4, 8, and 12 weeks after injection.
The purpose of this study is to compare the efficacy of two types of local anesthesia (articaine and lidocaine) for infiltration anesthesia during restorative dental procedures on lower teeth in pediatric patients. The patients will require similar dental operative procedures on both right and left sides of the mandible in order to qualify for this study. The study will require at least two dental appointments, where a randomized, cross-over study methodology will be utilized. All subjects will be treated by the same dentist. The comfort of the patient will be assessed at various points during the procedure using the Wong-Baker Faces Scale.
