Correlation of Various Laboratory Parameters With Outcome in Patients Suffering From Acute Non-traumatic...

Subarachnoid Hemorrhage

In this prospective study, the investigators aim to investigate the effect of the following three factors on the development of vasospasm and patient outcome: (1.) the role of anemia; (2.) the role of plasma fibrinolytic activity; (3.) the role of vitamin D. The investigators include patients admitted to the Neurosurgical Intensive Care Unit of the Clinical Center of the University of Debrecen with the diagnosis of subarachnoid hemorrhage (SAH). Patients are treated according to international guidelines. As part of the study protocol the following investigations are performed: • Hemoglobin level measurement: on the day of admission and day 3-4-7 and 14 after hemorrhage •Modified clot lysis assay (mCLA): on the day of admission and day 7 after hemorrhage •25-hydroxy vitamin-D level measurement: on the day of admission •Transcranial color-coded duplex sonography (detecting vasospasm): on daily basis. •30 day follow-up: mortality, Glasgow Outcome Scale (GOS), Karnofsky score, Barthel score •90 day follow-up: mortality, Glasgow Outcome Scale , Karnofsky score, Barthel score. Laboratory test results are correlated with (a) the development of vasospasm; (b) with 30 and 90 day outcome. Perspectives of the planned study: Considering the currently available therapeutic range for patients with SAH, results of the present study may provide a basis for designing further randomized, prospective trials to investigate the effect of treating anemia, anticoagulation and vitamin-D supplementation.

Study of Changes in CSF Ionic Composition After Aneurysmal Meningeal Hemorrhage

Subarachnoid Hemorrhage

Hyponatremia is a frequent complication of subarachnoid hemorrhage (SAH) with a prevalence of 30 to 50% in patients with this condition. This hydro-electrolytic disorder is responsible for an increase in morbidity with the appearance of neurological disorders. Also, it has been shown that there are ionic changes in the cerebrospinal fluid and a probable alteration of the blood-brain barrier in patients with SAH. The kinetics and relationship between hyponatremia and these changes remain unknown. The main objective of the study is to determine whether the change in cerebrospinal fluid (CSF) composition, precedes the development of hyponatremia. For this, the investigators propose to study the evolution of the CSF ionogram with the blood ionogram. Furthermore, they will perform additional analyses on the basis of a control group (CSF of patient with normal pressure hydrocephalus) to determine the effect of SAH on ionic changes. The hypothesis of the study is that there is a correlation between the change in CSF blood ionogram and the development of hyponatremia between day 0 and day 14.

Early Warning of Delayed Cerebral Ischemia

Subarachnoid HemorrhageAneurysmal5 more

The goal of this observational study is to learn about the possibility to predict clinical course of subarachnoid hemorrhage (SAH) patients by performing the retrospective analysis of clinical data available in early pre-vasospasm phase. The main questions it aims to answer are: What biomarkers retrieved from Computed Tomography (CT) and Computed Tomography Angiography (SAH location, leaked blood volume, cerebrospinal fluid volume, etc.) can be used to predict development of cerebral vasospasms, delayed cerebral ischemia and patients' outcome. What biomarkers retrieved from transcranial Doppler examinations in early pre vasospasm can be used to predict development of cerebral vasospasms, delayed cerebral ischemia and patients' outcome. What biomarkers retrieved from multimodal physiological monitoring in early pre vasospasm can be used to predict development of cerebral vasospasms, delayed cerebral ischemia and patients' outcome. What is impact of other clinical data (blood test results, age, gender, etc.) on development of cerebral vasospasms and delayed cerebral ischemia.

COAgulation Disorders in Ischaemic and Haemorrhagic Stroke

Ischemic StrokeHaemorrhagic Stroke1 more

In this study the investigators will assess both procoagulant and anticoagulant pathways using thrombin generation and platelet function tests in all patients presenting with ischaemic and haemorrhagic stroke (including aneurysmal subarachnoid haemorraghe). Also the cross-talk between inflammation and thrombosis, so-called thrombo-inflammation is further investigated. As such the investigators aim to characterise the patient's coagulation profile before administration of any treatment. By assessing these pathways the investigators strive to detect specific markers to predict vital and functional outcome at 3 months in these patients. Finally the investigators may provide new pathophysiological insights in the course of disease following these events that can possibly improve future therapeutic strategies.

Recovery After Cerebral Hemorrhage

Intra Cerebral HemorrhageSubarachnoid Hemorrhage2 more

Background: While the intensive care of patients with life-threatening brain illnesses has advanced tremendously, a large number of therapies are still without proper scientific support. This can be partly explained by the fact that mechanisms of initial brain injury are still not well understood. Why additional neurological injury occurs during a patient's stay in the NeuroCritical Care Unit (NCCU) despite current best, evidence-based clinical practices, is also not well understood. However, over the past decade, better tools have become available to measure and monitor the impact of our clinical care on the rapidly changing physiology and chemistry of the injured brain. Some of these tools are CT, MRI, ultrasound, and catheter-based technology measuring blood flow and metabolism. These tools have enabled earlier detection of injury and complications and newer therapeutic strategies. Purpose: Examine disease pathways common to all brain injuries seen in the University of Maryland's 22-bed NCCU. Life-threatening neurological illnesses cared for in the NCCU include massive stroke, bleeding in and around the brain (subarachnoid hemorrhage, intracerebral hemorrhage, subdural hemorrhage, intraventricular hemorrhage), brain tumors, difficult to control seizures, neurologic infections, nerve and muscle diseases (such as myasthenia gravis or Guillain-Barre Syndrome), and spinal cord disorders among others. Many NCCU patients are comatose or paralyzed and may suffer injuries in other parts of the body as well. This effort will require the creation of a robust clinical database for the capture of data including patient characteristics (age, sex), clinical characteristics, medical treatments, surgical interventions, physiological data (such as vital signs, cerebral blood flow, intracranial pressure, cerebral oximetry, etc), laboratory data, and standard-of-care diagnostic studies such as electroencephalography (EEG), ultrasound, CT, MRI, and angiograms. Similar databases exist at other major centers for neurocritical care and have been instrumental to the identification of characteristics both predictive of and associated with outcomes of patients long after their stay in the NCCU. In addition, the samples collected will be included in the University of Maryland Medicine (UMM) Biorepository which is a shared resource to enable biomedical research by University of Maryland faculty.

MUSic Therapy In Complex Specialist Neurorehabilitation

StrokeSubarachnoid Hemorrhage8 more

Aim: Investigate whether patients undergoing specialist rehabilitation after complex neurological injury show different functional outcomes if music therapy is included in their rehabilitation program compared to usual care. Background: Patients with complex needs following a brain, spinal cord, and/or peripheral nerve injury often require a period of specialist neurorehabilitation. This involves multiple therapy disciplines, led by a Consultant in Rehabilitation Medicine, Neurology, or Neuropsychiatry. Although music therapy is suggested to enhance neuroplasticity and recovery in patients with brain injury, it is not routinely commissioned in clinical care due to a lack of supportive evidence. Hypothesis: Patients undergoing music therapy in addition to complex specialist rehabilitation show better functional outcomes compared to usual care. Number of participants: 75, aged 16-80 years. Methods: Patients undergo baseline assessments and are randomised to MUSIC or CONTROL Therapy. Both arms receive 1-3 additional therapy sessions per week, matched for duration and number, total 15 hours. After approximately 10-weeks intervention, assessments are repeated. All participants then have access to music therapy until they are discharged from Neurorehabilitation Unit (NRU), with additional qualitative data collection using semi-structured interviews, field notes, staff reports, staff stress surveys, and broader ecological observations. Duration for Participants: From consent to discharge from NRU. Primary Outcome: Change in Functional Independence Measure+Functional Assessment Measure (FIM+FAM), Northwick Park Dependency Scale (NWPDS), and Barthel Activities of Daily Living pre and post 15 hours intervention. Secondary Outcome: Change in quality of life (Flourishing Scale), psychological distress (Hospital Anxiety and Depression Scale, Depression Intensity Scale Circles), social interaction (Sickness Impact Profile Social Interaction Subscale), well-being (WHO Well-Being Index), and communication (Communication Outcomes After Stroke Scale), pre and post 15 hours intervention. Mean difference in well-being (WHO Well-Being Index) throughout the intervention period between music therapy and control therapy groups. Mean difference in post-intervention pain and mood visual analogue scores between music therapy and control therapy groups.
