Patients with brain injury secondary to stroke, surgery, or trauma frequently suffer from homonymous hemianopia, defined as vision loss in one hemifield secondary to retro- chiasmal lesion. Classic and effective saccadic compensatory training therapies are current aim to reorganize the control of visual information processing and eye movements or, in other words, to induce or improve oculomotor adaptation to visual field loss. Patients learn to intentionally shift their eyes and, thus, their visual field border, into the area corresponding to their blind visual field. This shift brings the visual information from the blind hemifield into the seeing hemifield for further...
This is a prospective study that compares biofeedback training on the microperimetry (BT) to a control group in patient s with hemianopia. The patients receive 5 sessions of 20 minutes to stimulate with light and sound the brain in using the best residual area on the visual fields post-brain injury visual loss. Visual tests and quality of life questionnaire are performed pre-and-post-training.
The main purpose is to evaluate initial clinical experiences and to explore whether the Vision.X system yields improved image quality and diagnostic performance compared to Vision 600.
The objective of this study is to build a collection of biological samples from patients with brain tumors.
The BIOMEDE 2.0 study is the second stage of the BIOMEDE multi-arm, multistage rolling programme (adaptive platform protocol). It is a multicenter, randomized, open-label, controlled phase-3 trial evaluating efficacy of ONC201 in comparison with everolimus (primary objective based on internal comparison) and subsequently to historical controls. Two treatment groups will be compared. Study treatment will be continued until centrally confirmed disease progression (either radiologically or histologically), unacceptable toxicity or consent withdrawal. A switch between treatment groups is allowed after confirmation of the disease progression (real-time central review blinded to...
The purpose of this project is to validate a new combined MRI and PET imaging technique as a biomarker or measure of glycolysis in brain tumors. To accomplish this, the investigators propose obtaining image-guided measures of tissue pH and biopsied tissue in tumor areas selected for bulk resection surgery. Investigators will then correlate the imaging measurements with pH, RNA expression, protein expression, and bioenergetics measurements of key glycolytic enzymes.
The cerebral arteriovenous malformations correspond to the formation of an entanglement of morphologically abnormal vessels called nidus, which shunt the blood circulation directly from the arterial circulation to the venous circulation. The cerebral arteriovenous malformations are an important cause of hemorrhagic stroke. The hypothesis is that cerebral haemorrhage associated with a cerebral arteriovenous malformations would come from peri-nidal micro-vessels, in connection with infiltration of leucocytes and / or defective maintenance of microvascular integrity by platelets.
1. Screen and recruitment: patients will be screened based on their prior history and intention to initiate treatment with an immune checkpoint inhibitor. 2. Study phase: - Collection of baseline demographic data, prior disease history, nature of ICI therapy, outcome data of ICI therapy (treatment disposition, toxicity, tumor response and survival). - Collection of blood samples will be performed every 3 to 4 weeks for the first year on ICI therapy and every 6 to 12 weeks thereafter until the end of ICI therapy, disease progression, death or loss to follow-up. Collection of blood samples will be...
Neurological autoimmune diseases are a group of disorders characterized by the abnormal immune response attacking the nervous system, including the brain, spinal cord and peripheral nerves. These diseases exhibit high heterogeneity, diverse clinical presentations, and are challenging to diagnose and manage due to a lack of effective treatments. In this study, the investigators will recruit eight kinds of autoimmune diseases of nervous system including Neuromyelitis Optica Spectrum Disorder (NMOSD), Myasthenia Gravis (MG), Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP), idiopathic inflammatory myopathy (IIM), and multiple sclerosis (MS), autoimmune encephalitis...
Background: Immunotherapy has been successful in treating advanced melanoma, but a large proportion of patients do not respond to the treatment with immune checkpoint inhibitors (ICIs). Preclinical and small cohort studies suggest biomarkers from the primary tumor, stool and body fluids as markers of response. This prospective study will evaluate gastrointestinal microbiome (bacterial spices and virome) composition and exosomal mRNA expression of PD-L1 and IFNγ correlation with radiological response rates to ICIs treatment of advanced melanoma patients. Methods: Patients treated with immune checkpoint inhibitors as a first line treatment for metastatic melanoma are recruted to the...
