NCT01921751
This randomized phase II trial studies how well high or standard intensity radiochemotherapy after gemcitabine hydrochloride and paclitaxel albumin-stabilized nanoparticle formulation (nab-paclitaxel) work compared with gemcitabine hydrochloride and nab-paclitaxel alone in treating patients with pancreatic cancer that cannot be removed by surgery. Drugs used in chemotherapy, such as gemcitabine hydrochloride and nab-paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs, such as capecitabine, may make tumor cells more sensitive to radiation therapy. Giving radiation therapy in different ways and adding chemotherapy may kill more tumor cells. It is not yet known whether high intensity radiochemotherapy after gemcitabine hydrochloride and nab-paclitaxel is more effective than standard intensity radiochemotherapy after gemcitabine hydrochloride and nab-paclitaxel or gemcitabine hydrochloride and nab-paclitaxel alone in treating pancreatic cancer.
NCT03381911
This study will investigate how consent forms and other health care documents are explained to patients. The findings will be used to create a computer program that can successfully explain consent and other health-related forms to individuals who have difficulty reading and understanding consent forms on their own as a supplement to the normal consent process done in research settings. In a prior study, the investigators delivered a similar protocol, where subjects were first consented and then given a mock consent form (administered in 1 of 3 arms: RA, ECA, or ECA + RA). Subjects in this protocol struggled with the concept of a "mock" consent process, especially after they had just completed a consent process for the study itself. The current protocol, using deception research methods, aims to provide a more pure assessment of ECA consent vs the standard (here, E-consent) by waiving consent and delivering the sham consent as if it were reality. In the context of a protocol that employs deception methods, participants in the current study would be invited as healthy volunteers, and be randomized to 1 of 2 different consent processes to evaluate the relative benefits of different approaches for informed consent. After the knowledge tests have been completed, subjects will undergo a debriefing where they are made fully aware of the deception and its purpose. At that time, subjects will also be given the opportunity to "opt out" and not have their data included in the study results.

NCT02066129
The objective of this study is to determine whether, in children receiving low-dose inhaled corticosteroids (ICS), quintupling the dose of inhaled corticosteroids at the onset of symptoms previously associated with upper respiratory illnesses and subsequent asthma exacerbations reduces the rate of severe asthma exacerbations treated with oral corticosteroids.
NCT00166270

NCT03033550
The purpose of this study is to determine whether a mobile health educational intervention for Human PapillomaVirus (HPV) Vaccination promotion and cervical cancer screening in Primary Care settings is a feasible behavioral intervention to integrate as a primary and secondary cervical cancer prevention approach.Study Design: The investigators will conduct an open feasibility proof-of-concept trial using a single experimental group with all subjects receiving the behavioral intervention being studied. Outcome measures. The primary outcome of interest is receipt of the first dose and completion of the three-dose series of HPV vaccine within 6 month of intervention, this will be evaluated by Electronic medical review review.
NCT00940095
The aim of this study is to demonstrate that clazosentan, administered as a continuous intravenous infusion at either 5 mg/h or 15 mg/h until Day 14 post aneurysmal subarachnoid hemorrhage (aSAH), reduces the incidence of cerebral vasospasm-related morbidity and all-cause mortality within 6 weeks post-aSAH treated by endovascular coiling. The primary endpoint of the study is the occurrence of cerebral vasospasm-related morbidity, and mortality of all-causes within 6 weeks post-aSAH, defined by at least one of the following: 1. Death (all causes). 2. New cerebral infarct(s) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 3. Delayed ischemic neurological deficit (DIND) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 4. Administration of a valid rescue therapy in the presence of confirmed cerebral vasospasm on angiography (DSA or CTA). An independent Critical Events Committee (CEC) will adjudicate whether or not patients meet the primary endpoint and its individual morbidity components.
NCT00047125
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Giving radiation therapy in different ways may kill more tumor cells. It is not yet known which regimen of radiation therapy is more effective in treating patients who have metastases to the lymph nodes in the neck. PURPOSE: Randomized phase III trial to compare different radiation therapy regimens in treating patients who have metastases to the lymph nodes in the neck from an unknown primary tumor.
NCT02330055
The primary aim of the study is to evaluate the effect of the method of delivery (vaginal delivery vs. cesarean section) on oxygen saturation in the first postpartum night. The investigators hypothesize that nocturnal desaturation occurs more frequently in cesarean section compared with vaginal delivery, expressed as either the duration of SpO2 below 90% or the Oxygen Desaturation Index (ODI). The ODI is defined as number of oxygen desaturations by at least 3 % per hour. Furthermore, the investigators expect a higher pulse rate and a lower mean and minimum SpO2 in the cesarean section group compared with the vaginal delivery group. The secondary aim of the study is to investigate how the upper body position during sleep (45 degree elevated vs. non-elevated) affects the oxygen saturation during the first postpartum night. The investigators hypothesize that an upper body elevation to 45 degrees decreases the incidence of desaturation events, expressed as either the duration of SpO2 below 90% or the ODI , compared with a non-elevated body position within each delivery group (vaginal delivery or cesarean section). The third aim of the study is to identify independent predictors of nocturnal desaturation in postpartum women. To that end, the investigators will administer questionnaires and collect demographic and clinical data according to various obstructive sleep apnea screening scores, including the P-SAP, STOP-Bang, and Epworth Sleepiness Scale. The investigators will also ask the patient to rate the pain during the study night on a verbal numerical rating scale.
NCT00113555
The purpose of this study is to evaluate the safety and effectiveness of a minimally invasive surgical procedure in up to 160 implanted female patients in which two adjustable balloons (one on each side of the urethra) are implanted to treat urinary stress incontinence. The results will be analyzed to demonstrate the effects of the device as well as its associated risks. Therapeutic success will be based on whether the patients demonstrate at least a one-grade (mean) reduction in the Stamey score at 12 months.
NCT00344682
This study is evaluating the efficacy and safety of the drug memantine (trade name NAMENDA) as an augmentation agent for the treatment of depression in people who are not fully responding to antidepressant medications.
NCT00699283
Antiepileptic Drugs (AEDs) are the main treatment for epilepsy; however, only a limited number of AEDs are approved for use as monotherapy. The objective of this study is to evaluate the efficacy of BRV in the conversion of partial onset seizure patients from combination treatment to monotherapy.
