NCT03736174
The purpose of this study is to investigate high frequency ultrasound as a future modality for the diagnosis of chronic exertional compartment syndrome (CECS). The results of the ultrasound will help determine if there are any significant radiologic findings or patterns seen in patients with CECS.
NCT02918409
The purpose of this study is to find the safest and most effective way to administer IV antibiotics to treat acute pulmonary exacerbations (APEs) in patients with cystic fibrosis (CF) that are caused by pathogens, like Pseudomonas aeruginosa. This study will test the safety and effectiveness of two commonly prescribed IV antibiotics: tobramycin and colistin. Though regularly used, not much is known about how these drugs compare with each other in terms of their toxicities, both during short term treatment of an APE and after many treatment courses with these drugs over many years. There are currently no guidelines on the safest and most effective antibiotics to use when treating APEs. We will study kidney function, sputum cultures, and treatment outcomes in patients receiving routine administration of one of these two IV antibiotics. We will also test these outcomes in patients receiving a less frequent dosing schedule for IV colistin. The hope is that this new schedule for IV colistin, which is twice a day and adjusted based on blood and urine tests, will reduce harmful side effects, such as kidney damage, while still being a powerful treatment against CF microbial pathogens.
NCT01838174
We hypothesize that the novel melanocortin-mediated anti-inflammatory effects of ACTH will reduce axonal loss following ON by limiting inflammatory optic nerve injury. We will compare the effect of ACTH and intravenous methylprednisolone therapy on axonal injury following ON using OCT, a sensitive, reproducible and noninvasive tool to measure RNFL thickness. The primary outcome will be the average RNFL thickness at 6 months. Additional pre-specified statistical analyses will compare the difference in the mean RNFL thickness at 6 months in the affected eye between the IV methylprednisolone- and Acthar-treated groups, and the mean 6-month affected eye RNFL thicknesses adjusted for the baseline unaffected eye RNFL. The secondary outcome measure will examine the frequency of optic nerves with RNFL swelling between the IV methylprednisolone- and Acthar-treated groups at 1 and 3 months. A predefined exploratory outcome will compare the ganglion cell plus inner plexiform layer (GC+IPL) thickness at 6 months between treatment groups. Additional tertiary outcome will be the assessment of changes in fatigue, mood, visual function depression, and quality of life in patients with AON. Assessment will be completed by administration of the following questionnaires: Modified Fatigue Impact Scale, Multiple Sclerosis Quality of Life 54 Instrument, 25-item Visual Function Questionnaire with 10-item supplement, Beck's Depression Inventory. These questionnaires have been validated for the MS (AON) population. Descriptive and correlative analysis will be done at each visit time point to assess for QOL for this study population.
