Filter by:Resistant microorganisms are public health problems because they affect the treatment of infectious diseases and the survival of patients. Neurosurgical procedures with placement of intracranial pressure monitoring and external ventricular drainage devices are related to increased morbidity and mortality. In Brazil, there are several multicenter studies demonstrating the prevalence and types of resistant microorganisms, however, there is a lack of data related to central nervous system infections associated with invasive devices, which can have a direct impact on prevention and treatment policies.
All patients undergoing allogeneic or autologous HSCT at the participating centres will be observed. Once a diagnosis of CNS disorder is made, additional data will be reported for these patients. We will identify clinical and diagnostic characteristics such as cerebrospinal fluid (CSF) and neuroimaging patterns, risk factors, response to treatment (including novel antifungal agents such as isavuconazole) and outcome. In addition, risk factors for CNS disorders after allogeneic and autologous HSCT will be analyzed using a prospectively assessed matched control group. In the future, this study might be the basis for an interventional trial (e.g. using a prophylactic approach).
This study is a clinical trial to determine the safety of inoculating G207 (an experimental virus therapy) into a recurrent or refractory cerebellar brain tumor. The safety of combining G207 with a single low dose of radiation, designed to enhance virus replication, tumor cell killing, and an anti-tumor immune response, will also be tested.

The primary objective of the study is to evaluate the safety and immunogenicity of non-adjuvanted and adjuvanted monovalent VEE VLP Vaccine in healthy adults (ages 18-50 years) when administered via intramuscular (IM) injection at escalating doses of 2 μg, 10 μg, and 20 μg as a 2-dose primary series (Day 0, Day 28) with a Day 140 booster dose. The secondary objective of the study is to evaluate immunogenicity of the vaccine at the aforementioned time points
This phase II trial studies the side effects and how well nivolumab and ibrutinib works in treating patients with central nervous system lymphoma that has come back or does not respond to treatment. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Ibrutinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving nivolumab and ibrutinib may work better in treating patients with central nervous system lymphoma.
This is a Phase 1 study of central nervous system (CNS) locoregional adoptive therapy with autologous CD4+ and CD8+ T cells that are lentivirally transduced to express an EGFR806 specific chimeric antigen receptor (CAR) and EGFRt. CAR T cells are delivered via an indwelling catheter into the tumor cavity or the ventricular system in children and young adults with recurrent or refractory EGFR-positive CNS tumors. The primary objectives of this protocol are to evaluate the feasibility, safety, and tolerability of CNS-delivered fractionated CAR T cell infusions employing intra-patient dose escalation. Subjects with supratentorial tumors will receive sequential EGFR806-specific CAR T cells delivered into the tumor resection cavity, subjects with infratentorial tumors will receive sequential CAR T cells delivered into the fourth ventricle, and subjects with leptomeningeal disease will receive sequential CAR T cells delivered into the lateral ventricle. The secondary objectives are to assess CAR T cell distribution within the cerebrospinal fluid (CSF), the extent to which CAR T cells egress into the peripheral circulation, and EGFR expression at recurrence of initially EGFR-positive tumors. Additionally, tumor response will be evaluated by magnetic resonance imaging (MRI) and CSF cytology. The exploratory objectives are to analyze CSF specimens for biomarkers of anti-tumor CAR T cell presence and functional activity.
This is a Phase 1 study of central nervous system (CNS) locoregional adoptive therapy with autologous CD4 and CD8 T cells lentivirally transduced to express a HER2-specific chimeric antigen receptor (CAR) and EGFRt, delivered by an indwelling catheter in the tumor resection cavity or ventricular system in children and young adults with recurrent or refractory HER2-positive CNS tumors. A child or young adult with a refractory or recurrent CNS tumor will have their tumor tested for HER2 expression by immunohistochemistry (IHC) at their home institution or at Seattle Children's Hospital. If the tumor is HER2 positive and the patient meets all other eligibility criteria, including having a CNS catheter placed into the tumor resection cavity or into their ventricular system, and meets none of the exclusion criteria, then they can be apheresed, meaning T cells will be collected. The T cells will then be bioengineered into a second-generation CAR T cell that targets HER2-expressing tumor cells. The patient's newly engineered T cells will then be administered via the indwelling CNS catheter for two courses. In the first course they will receive a weekly dose of CAR T cells for three weeks, followed by a week off, an examination period, and then another course of weekly doses for three weeks. Following the two courses, patient's will undergo a series of studies including MRI to evaluate the effect of the CAR T cells and may have the opportunity to continue receiving additional courses of CAR T cells if the patient has not had adverse effects and if more of their T cells are available. The hypothesis is that an adequate amount of HER2-specific CAR T cells can be manufactured to complete two courses of treatment with three doses given on a weekly schedule followed by one week off in each course. The other hypothesis is that HER-specific CAR T cells safely can be administered through an indwelling CNS catheter to allow the T cells to directly interact with the tumor cells for each patient enrolled on the study safely can be delivered directly into the brain via indwelling catheter. Secondary aims of the study will include to evaluate CAR T cell distribution with the cerebrospinal fluid (CSF), the extent to which CAR T cells egress or traffic into the peripheral circulation or blood stream, and, if tissues samples from multiple time points are available, also evaluate the degree of HER2 expression at diagnosis versus at recurrence.
This research study is studying a drug called atezolizumab as a possible treatment HER2-positive metastatic breast cancer (MBC) that has spread to the brain. The names of the study drugs involved in this study are: - Atezolizumab - Pertuzumab - Trastuzumab
In this case-control study, the investigators compare shoulder muscle function, pain, and central nervous system sensitization in patients with Subacromial Pain (SAP) to that in healthy controls. The investigators also examine if a relationship exists between shoulder symptom duration and central sensitization, shoulder muscle function and shoulder pain distribution in patients with SAP.
This is a prospective randomized clinical trial, to determine whether dose-intensive tandem Consolidation, in a randomized comparison with single cycle Consolidation, provides an event-free survival (EFS) and overall survival (OS). The study population will be high-risk patients (non-Wnt and non-Shh sub-groups) with medulloblastoma, and for all patients with central nervous system (CNS) embryonal tumors completing "Head Start 4" Induction. This study will further determine whether the additional labor intensity (duration of hospitalizations and short-term and long-term morbidities) associated with the tandem treatment is justified by the improvement in outcome. It is expected that the tandem (3 cycles) Consolidation regimen will produce a superior outcome compared to the single cycle Consolidation, given the substantially higher dose intensity of the tandem regimen, without significant addition of either short-term or long-term morbidities.
