Filter by:Patients may participate in this research study if they have glioblastoma. (a brain tumor) that has come back after being treated. Standard treatment for this cancer is a chemotherapy drug called bevacizumab. This research study involves bevacizumab in combination with a special diet called the Modified Atkins Diet (MAD). The purpose of this study is to research if patients can stay on the MAD when it is added to the standard bevacizumab treatment.
The aim of this study is to evaluate the effect of acupuncture on inflammation and immune function after craniotomy. This study will be a single-center, parallel group clinical trial that will be conducted at Kyung Hee University Hospital at Gangdong, Seoul, Korea.
Project title: Influence of Vasopressors on Brain Oxygenation and Microcirculation in Anesthetized Patients with Cerebral Tumors Sponsor-investigator: Klaus Ulrik Koch M.D. Sponsor: Department of Anesthesia Aarhus University Hospital, Nørrebrogade 44, 8000 Aarhus C, Denmark Objective: To investigate whether phenylephrine and ephedrine causes different alterations in microcirculation and oxygenation, as measured with MRI and PET, in anesthetized patients with brain tumors. Using MRI and PET, the study will assess whether there is a difference in deoxyhemoglobin concentration (Bold signal), CTTH, cerebral blood flow (CBF) and cerebral metabolic rate of oxygen (CMRO2) between ephedrine and phenylephrine Method: Double blinded controlled randomized clinical trial. Either phenylephrine or ephedrine are infused intravenously under general anesthesia. MRI is performed in 20 patients before and after infusion. PET/CT is performed in 20 patients before and after infusion. BIS and NIRS monitoring will be used in either scanner. After scanning patients are transported to the operating theatre and the craniotomy is performed. After removal of the bone flap subdural ICP is measured and recorded. MRI to analyze CBF, CTH, max.CMRO2, maxOEF, CBV and grey-scale ADC before and after ephedrine and phenylephrine. PET/CT to analyze CBF and CMRO2 before and after ephedrine and phenylephrine and calculation of OEF. During each PET/CT scan session oxygen saturation and hemoglobin concentration is measured. Data from the proposed studies will add substantial new knowledge to the investigators current understanding of the effects of vasopressors on cerebral circulation. This information will aid the neuroanesthesiologist, neurointensivist and the neurosurgeon in the choice of the optimal method to manage cerebral perfusion pressure during craniotomy for brain tumor.
A wide spectrum of methods is used to image brain activation in vivo. It can be directly detected by neurons electrical activity imaging (cortical simulation mapping, calcium imaging, voltage sensitive dyes) or indirectly by imaging hemodynamic changes induced by the neurovascular coupling in the vessels surrounding the activated neurons (intrinsic optical imaging, photoacoustic imaging, positron emission tomography (PET), functional magnetic resonance imaging (fMRI)). Ultrasound as the potential to complement these functional imaging techniques at low cost. Ultrasound imaging can do real-time in-depth imaging of brain. However, its use to imaging of major vessels has been limited until now due to its poor sensitivity. To overcome this limitation functional ultrasound (fUS) was developed in Institut Langevin since 2011. This technique enables high spatio-temporal resolution imaging of whole-brain microvasculature dynamics in response to brain activation without the need of contrast agent. This fUS method relies on a new power Doppler imaging sequence sensitive enough to detect blood flow in most of cerebral vessels (arterioles, big venules and larger vessels). Repeating the acquisition of such ultrasensitive Doppler images over time enables to follow flow dynamics in such vessels modulated by local neuronal activity. Applied to the rat brain, fUS was proved able to map brain activation at high spatiotemporal resolution and high signal to noise ratio. The aim of this study is now to apply fUS on human brain in intraoperative condition. The main objective of this study is to find activation maps through intraoperative ultrasensitive Doppler compared to gold standard cortical simulation mapping and functional MRI. Secondly the investigators want to test sensitivity of this new Doppler mode. fUS method will be used for different types of stimuli and intensity and the investigators will do some control acquisitions. Blood vessel density observed with a conventional Doppler will be compared to the one measured with the ultrasensitive Doppler to prove that this new Doppler mode enhance micro vessel visualization.
Despite theoretical benefits of intravenous agents, volatile agents remain popular. In a study comparing desflurane, isoflurane, and sevoflurane in a porcine model of intracranial hypertension, at equipotent doses and normocapnia, cerebral blood flow (CBF) and intra-cranial pressure (ICP) were least with sevoflurane. Propofol is the most commonly used intravenous anesthetic. It has many theoretical advantages by reducing cerebral blood volume (CBV) and ICP and preserving both autoregulation and vascular reactivity. Neurosurgical patients anaesthetized with propofol were found to have lower ICP and higher CPP than those anaesthetized with isoflurane or sevoflurane. The well known pharmacodynamic advantages of intravenous anesthetics may give this group of drugs superior cerebral effects when compared with inhalation anesthetics.
This study evaluates the use of fentanyl during craniotomy in two groups of brain tumor patients. The control group will receive standard general anesthesia with the use of fentanyl for intraoperative pain control and the study group will receive scalp nerve block with 0.5% levobupivacaine (local anesthetic) and also fentanyl for intraoperative pain control. The scalp nerve block might reduce the dose of fentanyl and promote faster emergence from general anesthesia.
RATIONALE: Placing a tumor antigen chimeric receptor that has been created in the laboratory into patient autologous or donor-derived T cells may make the body build immune response to kill cancer cells. PURPOSE: This clinical trial is studying genetically engineered lymphocyte therapy in treating patients with Relapsed and/or Chemotherapy Refractory Advanced Malignancies.
The purpose of this study is to test the efficacy of a clinic-based intervention designed to reduce illness uncertainty for parents of children who have been recently diagnosed with cancer.
Laser Interstitial Thermal Therapy (LITT) is a minimally invasive surgical technique that allows for biopsy and thermal ablation of brain tumors. Pediatric patients with brain tumors who are eligible and enroll in the trial will undergo LITT at the time of diagnosis or at the time of recurrence/progression rather than undergo an open craniotomy and tumor resection/biopsy. LITT will include a stereotactic biopsy followed by thermal ablation of the tumor. This study will monitor the safety and efficacy of LITT for the treatment of pediatric brain tumors.
Hematopoietic cell transplantation (BMT), or commonly referred to as blood and marrow transplantation (BMT), is a potentially life-saving therapy for many malignant and non-malignant conditions. Despite advances over the past decade, which have led to improved outcomes, BMT remains an intense treatment modality often requiring prolonged inpatient-based care. While many patients endure the acute complications of the procedure, it is common for BMT patients and their caregivers to experience increased risk of financial and emotional burden, hospital readmission, and health service utilization. This highlights the importance of active involvement of BMT patients in their own health care (self-efficacy). For pediatric BMT patients, parents are the primary caregivers. As such, parental activation on behalf of the child (patient) plays a critical role in effective patient-parent-provider partnerships, which is increasingly recognized as the optimal model for health care delivery, particularly for those facing life-altering medical treatments. It is essential to develop effective strategies to enhance this partnership. Health information technology (IT)-mediated tools offer the potential to overcome constraints in health care delivery limited by provider time, complicated health information, and financial pressures. Significant gaps in knowledge exist on the use of health IT tools using low-cost and well-accepted delivery platforms in routine inpatient care, especially for high-risk or critically ill populations. The investigators hypothesize that a tablet-based tool displaying personal health information could provide a platform to promote caregiver (parent) activation and enhance health communication. In this clinical research study, the investigators will conduct a pilot study of an educational health IT system developed on a tablet (Apple iPad®) that the investigators refer to as a Personalized Engagement Tool (PET) or the "BMT Roadmap." The Apple iPad® was selected as the platform for delivery of the educational intervention given its ergonomic features. The implementation and evaluation of the BMT Roadmap information system in caregivers of children undergoing BMT have been based on the generation of user (caregivers and patients) needs that incorporated well-established user-centered design processes including qualitative and quantitative research methods (published and unpublished data). The assembled investigators represent a strong multidisciplinary team with complementary and integrated expertise who are well-poised to carry out the proposed research. The Protocol or Study Team includes pediatric BMT physicians, Center for Health Communications Research (CHCR) staff, health informaticist, biostatistician, and psychologist. This research study is innovative because it addresses a gap in the literature on the role of health IT in parent activation on behalf of the child in the inpatient setting of a high-risk BMT population. The BMT Roadmap information system provides a robust experimental framework for further testing the utility of other care components that relate to parent activation or participation and for potential adoption in other complex medical conditions. The new knowledge gained herein will thus contribute to the evidence base of how health IT improves health care quality and provide the basis of further study in a full-scale clinical trial.
