Filter by:The high prevalence of myopia - especially in Asian countries - is well documented, as are the sight-threatening complications of high or degenerative myopia. Retinal detachment, glaucoma, vitreal degeneration and focal retinal changes occur secondary to the progressive axial elongation of the eye with age. Specialty rigid lenses have long been shown to lessen this progression in the pediatric population; orthokeratology (ortho-k) lenses are worn at night and change the corneal topography to correct low to moderate amounts of myopia. This same axial elongation has also been shown to occur in young adults with high near demands, however to our knowledge, there are no studies examining the effect of ortho-k lenses in this population. Our project seeks to investigate the efficacy of ortho-k in slowing axial elongation and myopic progression in subjects between the ages of 21-30. Results will help elucidate what role these specialty lenses may have in the management of the myopic patient throughout their development, as well as what potential they have in prevention of associated degenerative changes.
This was a prospective, open-label study with no participant randomization. Treatment for aHUS was observational and at the discretion of the treating physician. The purpose of this study was to assess disease manifestations of complement-mediated thrombotic microangiopathy (TMA) and evaluate potential clinical predictors of disease manifestations and progression in participants with aHUS with or without eculizumab treatment in the clinical setting.
The purpose of the study is to investigate whether the combination of obinutuzumab and ibrutinib (administered up to 840 mg per day) might be useful for the treatment of CLL or SLL that is not responding or no longer responding to treatment with ibrutinib alone. The study will evaluate whether this regimen can reduce the amount of cancerous cells in the body. Subjects will be treated with ibrutinib at a dose of up to 840 mg a day by mouth, as well as obinutuzumab infusions. Although both of these agents are approved by the FDA for the treatment of CLL or SLL, the combination and the dosing schedule of ibrutinib are considered experimental.
This non-interventional retrospective chart review study aims to evaluate the clinical outcomes of patients with RRMM receiving lenalidomide/dexamethasone (Len/Dex) treatment at 1st relapse and the treatment patterns following progressive disease as part of the routine clinical practice in Greece.
While the last several years have seen great strides in the treatment of relapsing forms of MS, progressive MS, responsible for the majority of MS-related disability, lags far behind. Despite much research, the lack of understanding related to what causes patients' relentless decline in function results in an inability to develop targeted treatment strategies suitable for clinical trials. This grant has two main goals. The first goal is to extend the investigators preliminary study on rat neurons treated with the CSF of MS patients to a larger number of Progressive patients in order to validate the initial findings and extend the study to include analysis of human neurons. The initiating PI (Dr. Casaccia) and the Partnering PI and Clinical Neurologist (Dr. Katz Sand) have recently identified components that are present in the CSF of progressive patients that impair the ability of rat neurons to produce energy. The partnering PI, Dr. Quinzii (Columbia University) together with collaborator Dr. Fossati (NY Stem Cells Foundation), have characterized human neurons generated from stem cells derived from skin biopsies of progressive patients and detected the presence of energetic deficits. The experimental plan will build on these results and test hypotheses of disease progression. The overall goal is to improve understanding on how to stop neurons from degenerating and stop clinical progression. The second goal is to ask whether it is possible to define a progressive disease course on the basis of combined biochemical, functional and imaging measurements. The initiating PI will be responsible for the biochemical assessment of CSF and serum samples and, together with partnering PI Quinzii, will also provide functional bioassays measurements of mitochondrial bioenergetics impairment in patients. These data will be combined with clinical assessment and MRI evaluations conducted by the partnering PI Katz Sand and collaborator Inglese. A two year clinical and imaging follow up from the initial recruitment will allow to define whether the combined measurements can be used by clinical neurologists to define the disease course and better identify therapeutic options for patients. The expectation is that the completion of the stated aims of research will allow an advancement of the current knowledge of the progressive form of MS and lead to potential new therapeutic targets.
Glaucoma is the leading cause of irreversible blindness worldwide. This study aims to test a new method that may allow earlier diagnosis of glaucoma and better ways to monitor if it is getting worse. There is scientific evidence that the macula, the central part of the retina, can be involved in very early stages of glaucoma. Glaucomatous damage to the macula is very prevalent and is often missed using conventional clinical tests. Relatively little is known about progression of early glaucoma damage and its effects on the macula. This project investigates the nature of progressive damage to the macula and proposes new methods to improve accuracy to detect clinically significant progression.The study will evaluate the nature of damage to the macula's structures through OCT imaging and eye function via visual field tests.
The purpose of the study is to verify the clinical effectiveness of a managed home telemonitoring program in patients with severe COPD against usual clinical practice, as measured by the decrease in the number of exacerbations, number of hospitalizations, hospital days and emergency room visits in a 12 month period The primary endpoint of effectiveness is "severe exacerbations avoided." The main hypothesis is that patients with severe or very severe COPD patients managed with a home telehealth program have better outcomes than patients managed according to usual clinical practice.
The investigators aim to evaluate the feasibility of a larger clinical trial assessing an exercise program during the "teachable moment" in patients with prostate cancer and measuring its effect on tumor apoptosis signaling, lipogenesis and steroidogenesis. Participants will be randomized between a 4-12 week exercise program or to standard of care only. Participants will be assessed at screening, baseline (day 0), throughout the trial intervention (days 1-84), post-intervention visit (prior to radical prostatectomy) and final study visit 6-months post-radical prostatectomy. At each assessment, physical, biological samples and psychosocial assessments will take place.
Consequences of latent cytomegalovirus (CMV) infection reactivation on ulcerative colitis flare, as a flare-worsening factor or simple bystander, are debated. Theoretically, CMV-specific cell-mediate immune response will further categorize the patients into high or low risk of CMV colitis. The investigators thus evaluate the usefulness of CMV-specific ELISPOT assay in patient with ulcerative colitis flare to assess the the impact of CMV colitis on ulcerative colitis flare.
The purpose of the study is to compare effectiveness of paliperidone palmitate (PP: paliperidone palmitate once-monthly and 3-month injections) versus oral antipsychotic (OAP [that is oral paliperidone extended release {ER}, oral risperidone, or another OAP]) in delaying time to treatment failure. The study will also evaluate changes in cognition, functioning, brain intracortical myelin (ICM) volume following treatment with PP compared with OAP in participants with recent-onset schizophrenia or schizophreniform disorder.
