This trial investigates brain and pelvic floor muscle activity in patients undergoing robot-assisted radical prostatectomy. This trial may help identify the brain waves that are associated with muscles involved in giving patients control over the bladder.
During a brain surgery targeted to remove a brain tumor, the neurosurgeon wakes up the patient to delimit the tumor area exactly, and identify the surrounding areas, to limit the surgery damages. The present project aims at testing the patient in this awake phase to determine the brain areas implied in time to contact (TTC) perception, a function that allows determining the arrival time of moving objects and used in many tasks of our daily life.
This clinical trial studies the use of 7-Tesla (7T)and 3T magnetic resonance imaging (MRI) in detecting brain diseases. 7T MRI has increased detection sensitivity, including more accurate lesion delineation, higher inter-rater agreement. Diagnostic procedures such as 7T MRI may help ultimately improved diagnostic and therapies confidence to inform decision making than standard 3T MRI.
Background: Accessing brain tumor material for pathological diagnosis requires invasive procedures that carry risk to patients including brain hemorrhages and death. Liquid biopsies are emerging non-invasive alternatives to direct tumour biopsies but the abundance of circulating tumor DNA (ctDNA) is relatively low and this limits our ability to accurately make the molecular diagnosis of brain tumors. We have recently shown promising results that suggest that the analysis of blood samples can distinguish brain tumor types. We now want to couple liquid biopsies with high intensity focused ultrasound (HIFU) to enhance the release of tumor DNA into the circulation and increase the...
This registry aims to collect clinical and radiologic information including detailed clinical, conventional MR and advanced MR imaging data of patients with brain gliomas. Advanced MR imaging may include diffusion-weighted imaging, perfusion-weighted imaging (dynamic susceptibility contrast, arterial spin labeling, dynamic contrast enhancement), and chemical exchange saturation transfer (CEST) imaging. This registry will describe course of disease and long-term outcomes of brain gliomas.
Endocrine therapy (ET) is widely used to treat hormone receptor positive breast cancer and prevent recurrence by downregulating estrogen function. However, ETs readily cross the blood brain barrier and interfere with the action of estrogen in the brain. Estrogen supports cognition and menopausal status is closely linked to cognitive health in women. This has raised concern that anti-estrogen ETs may affect cognition and brain health in breast cancer survivors. However, evidence across existing studies is inconsistent and these effects remain poorly understood. The incomplete understanding of the effects of ET are likely due to limitations of earlier studies - namely, the...
A biomarker is a measurable indicator of the severity or presence of some disease state. In this study, brain metastases patients who will be receiving radiation treatment, will undergo CT (Computed Tomography) and MRI (Magnetic Resonance Imaging) scans prior to and after radiation treatment to measure these biomarkers. This is a single-center phase II study to validate the predictive abilities of biomarkers, in terms of determining how patients will respond to radiation treatment.
This study is the experimental study for brain metastasis development mechanism in patients with breast cancer with brain metastasis
This study is a single-center, prospective, single-arm clinical trial, which intends to enroll patients with triple-negative breast cancer with brain metastases to receive ivonescimab combined with TROP2 ADC (such as sacituzumab govitecan) treatment until disease progression, intolerable toxicity, withdrawal of informed consent, or the investigator deems it necessary to discontinue the medication, and to collect data on the drug's efficacy and safety.
Anti-CASPR2 limbic encephalitis (CASPR2-LE) is a rare neurological disorder primarily affecting males over the age of 50. It is mediated by an autoimmune antibody response in the central nervous system (CNS) against the cellular adhesion molecule contactin-associated protein-like 2 (CASPR2). This protein plays an important role in the trafficking of KV1 channels under the myelin sheath in the juxtaparanodal region of myelinated axons. It is mostly present in the neurons of the limbic system, basal ganglia, and other motor related and sensation areas (Qin, Yang, Zhu, Wang, & Shan, 2021). This distribution explains the diverse clinical manifestations of the disease, primarily...
