Filter by:Magnetic resonance imaging, MRI, is a procedure that uses radio waves, a powerful magnet, and a computer to make a series of detailed pictures of areas inside the body. The goal of this study is to determine if MR fingerprinting, new way of acquiring MRI images, can help identify the extent of tumor spread in the brain, better than routine MRI images.
This research study will compare the cosmetic outcomes, specifically scar assessment and complications, between two surgical approaches for treating frontal skull base lesions: the endoscopic supraorbital eyebrow craniotomy and the conventional frontal craniotomy. The study will aim to evaluate the differences in scar appearance, spread, erythema, suture marks, hypertrophy/atrophy, and overall impression between the two approaches using the Scar Cosmesis Assessment Rating (SCAR) scale. Additionally, it will examine patient-reported outcomes such as itch and pain. The study will follow a structured protocol, including random allocation to groups, preoperative assessments, surgery, postoperative follow-ups, and statistical analysis. It will emphasize the importance of understanding cosmetic outcomes to improve patient satisfaction and inform treatment regimens.
The goal of this Phase 3 clinical trial is to compare the efficacy of niraparib versus temozolomide (TMZ) in adult participants with newly-diagnosed, MGMT unmethylated glioblastoma multiforme (GBM). The main questions it aims to answer are: Does niraparib improve progression-free survival (PFS) compared to TMZ? Does niraparib improve overall survival (OS) compared to TMZ? Participants will be randomly assigned to one of two treatment arms: niraparib or TMZ. - study drug (Niraparib) or - comparator drug (Temozolomide - which is the standard approved treatment for MGMT unmethylated glioblastoma). The study medication will be taken daily while receiving standard of care radiation therapy (RT) for 6-7 weeks. Participants may continue to take the niraparib or TMZ adjuvantly as long as the cancer does not get worse or completion of 6 cycles of treatment (TMZ). A total of 450 participants will be enrolled in the study. Participants' tasks will include: - Complete study visits as scheduled - Complete a diary to record study medication
Brain tumors involve different age groups with a wide range of tumor types involving different anatomical compartments of the brain. The evolution of the brain in vertebrates, including the most recent homo species (including humans), has occurred through increasing structural complexity in more evolved species. In the retrospective study, we will investigate the location of the tumors and different structural aspects of skull anatomy in patients with brain tumors. The information will be compared with the anatomical evolution of the brain and skull in vertebrates to look for possible associations, which can provide insights into evolutionary biology.
The goal of this clinical investigation of a medical device is to test the safety of graphene based electrodes when used during surgery for resection of brain tumors. The main questions that it aims to answer are: - To understand the safety of these new electrodes when used during brain tumor surgery (primary objective); - To assess the quality of the brain signals recorded with the new electrodes, their ability to stimulate the brain, how stable their function is over the duration of an operation, and their suitability for use in the operating theatre (secondary objectives). Participants will undergo tumor surgery as usual with the study electrodes being tested alongside a standard monitoring system. If they are awake for part of their surgery they may be asked to complete specific tasks such as naming objects from a list modified for the study. They will be monitored subsequently for any complications including undergoing an additional MRI scan 6 weeks after their surgery.
Analyzing the impact of surgery and adverse events (AEs) on patients' well-being is of paramount importance as it provides essential information for benefit-risk assessment. Current methods in outcome research are static, resource-intensive and subject to missing-data issues. Moreover, AEs are inconsistently reported using various grading systems that usually do not account for patients' subjective well-being. These are severe drawbacks for outcome research as it hinders monitoring, comparison, and improvement of treatment quality. The increasing use of smartphones offers unprecedented opportunities for data collection. We developed a free smartphone application to assess fluctuations of patients' well-being as a result of surgical treatment and possible AEs. The application is installed on each patient's smartphone and collects standardized data at defined timepoints before and after surgery (well-being, AE description and severity). By acquiring longitudinal patient-reported outcome before and after neurosurgical interventions, we aim to determine the regular postoperative course for specific surgical procedures, as well as any deviation thereof, depending on the occurrence and severity of AEs. We will evaluate the validity of existing AE classifications and, if necessary, propose a new patient-centered scheme. We hope that this will result in an increase in standardized reporting of patient outcome, and ultimately allow for evidence-based patient information and decision-making.
Impairments in aspects of social cognition are disorder-transcending: these have been demonstrated in various neurological disorders, such as traumatic brain injury (TBI), stroke, brain tumours (both low grade glioma's and meningioma's) and multiple sclerosis (MS). Social cognition involves processing of social information, in particular the abilities to perceive social signals, understand others and respond appropriately (Adolphs 2001). Crucial aspects of social cognition are the recognition of facial expressions of emotions, perspective taking (also referred to as mentalizing or Theory of Mind), and empathy. Impairments in social cognition can have a large negative impact on self-care, communication, social and professional functioning, and thus on quality of life of patients. Recently, a first multi-faceted treatment for social cognitive impairments in TBI was developed and evaluated; T-ScEmo (Training Social Cognition and Emotion). T-ScEmo turned out to be effective in reducing social cognitive symptoms and improving daily life social functioning in this particular group, with effects lasting over time (Westerhof-Evers et al, 2017, 2019). Unfortunately, up till now there are no evidence based, transdiagnostic treatment possibilities available for these impeding social cognition impairments in neurological patient groups, other than TBI. Therefore the aim of the present study is to investigate whether T-ScEmo is effective for social cognition disorders in patients with different neurological impairments, such as stroke (including subarachnoidal haemorrhage (SAH)), brain tumours, MS, infection (meningitis, encephalitis) and other. The secondary objective is to determine which patient related factors are of influence on treatment effectiveness. In short, hopefully this study can contribute to a treatment possibility for social cognition disorders for all patients with various neurological disorders. It is expected that T-ScEmo will be effective for various neurological disorders, based on previous research of Westerhof-Evers et al. (2017, 2019). Since social cognition disorders within patients with traumatic brain injury do all have the same ethiology it is expected that the treatment will show the same effects for patients with various neurological disorders. Therefore it is expected that patients will improve on social cognition, social participation and quality of life and social behaviour, that these results will last over time.
This will be a prospective, open-label, single-arm pilot study to investigate the safety and efficacy of Bevacizumab (BEV) in combination with microbubble (MB)-mediated FUS in patients with recurrent GBM. BEV represents the physician's best choice for the standard of care (SoC) in rGBM after previous treatment with surgery (if appropriate), standard radiotherapy with temozolomide chemotherapy, and with adjuvant temozolomide.
This Phase 2 trial will assess the safety, tolerability, efficacy, imaging pharmacodynamics, and pharmacokinetics of RVP-001, a novel manganese-based MRI contrast agent, at three escalating dose levels. RVP-001 will be administered as a single IV bolus to subjects with known gadolinium-enhancing central nervous system (CNS) lesions (for example stable brain tumor or multiple sclerosis) who have recently had a gadolinium-based contrast agent (GBCA)-enhanced MRI of the brain.
Primary and secondary brain tumors, the leading cause of death from cancer before the age of 35, represent a complex and heterogeneous group of pathologies with a generally poor prognosis. Knowledge of these tumors has made enormous strides thanks to access to biological samples, leading to a much more robust, reliable and precise histo-pronostic classification, but also, increasingly, to the identification of theranostic targets. Despite these advances, there is a real need to refine diagnostic and prognostic classification, identify the biological mechanisms involved in the formation and progression of these pathologies, develop new targeted strategies, and devise minimally invasive follow-up methods (liquid biopsies). In addition, certain non-tumoral brain lesions (e.g. malformations) can be similarly classified according to their molecular and mutational profile. This project aims to make a decisive contribution to these objectives.
