The CLOQS Trial - Countdown Lights to Optimize Quality in Stroke

To reduce door-to-needle times in acute stroke treatment. Using an organizational behaviour intervention (a large stopwatch), we will post a visual cue to remind all parties that "time is brain". We hypothesize that this simple visual cue will improve door-to-CT scan times and door-to-needle treatment times, and thus improve treatment response, and reduce adverse events.

Cooler Dialysis and Liver Perfusion and Function

Having hemodialysis affects the blood supply to various organs in the body including the heart and the brain. With time, these effects build up and can affect the way these organs function. We have previously shown that the liver (a key organ which works to help clean the blood, make proteins and turn all your food into energy) is also affected. One of the ways to help protect organs from injury due to dialysis has been cooling during dialysis. We want to examine whether coolin...


A Dose Finding Study Of A New Medication, PF-00337210 That Will Possibly Decrease Blood Supply To Tumors

This study will test a new cancer medication to determine if this medication will block blood supply to a tumor and decrease growth of a tumor. This study will also define the safety profile and define the safest dose of this new medication for people who have cancer.

Home Evaluation of Exit Barriers in Wandering

Main hypothesis. Floor and door visual exit barriers will decrease the frequency and duration of pre-elopement behaviors (lingering and shadowing) proximal to exit doorways, thus supporting the ability of caregivers to provide safe care at home and preventing or delaying home-to-institutional transfer of veterans with dementia who wander.

Optical Assessment on Brain Death Via a Oxygen Supply Procedure

This study aims to evaluate brain death with optical probes. The changes of hemodynamic parameters including oxyhemoglobin (HbO2) and deoxyhemoglobin (Hb) were detected by near infrared spectroscopy probes attached on the forehead of patients. A multiple-phase protocol at varied fraction of inspired O2 were utilized during the assessment.

Oxford Haemodynamic Adaptation to Reduce Pulsatility Trial

Chronic damage to small blood vessels deep in the brain is seen in half of patients over the age of 60 and almost all patients over the age of 80, and is responsible for up to a third of strokes and almost half of patients with dementia. However, there is limited evidence for how small vessel disease develops and no specific treatment. One potential explanation is that greater pulsations in blood pressure are transmitted to the brain through stiff blood vessels, resulting in in...

The Effect of Alemtuzumab on the Blood-brain-barrier and the Brain's Metabolism in Multiple Sclerosis Patients

The development and progression of multiple sclerosis seem to be driven by concomitant inflammation and, to a less well-defined degree, disturbances in metabolism of individual cells of the human central nervous system as well as changes in the dynamical supply of blood to the brain. These alterations in normal physiology can be quantified by investigating the change in specific parameters over the time course of multiple sclerosis evolution. Amongst these specific parameters, ...

A Study of Blood Pressure and Blood Supply to the Brain in Persons With a Spinal Cord Injury.

The purpose of this study is to determine how blood pressure and blood flow are controlled during head-up tilt in a semi-upright position. In this investigation we are studying blood pressure and blood flow to the brain, with and without a medication which lowers blood pressure (Vasotec). We will determine how persons with a spinal cord injury are able to maintain blood flow to the brain (not get dizzy) as they assume a more upright position and their blood pressure decreases.

Importance of Substance P in Intracranial Pressure Elevation Following Traumatic Brain Injury

Traumatic brain (TBI) injury is the major cause of morbidity and mortality worldwide especially in population under 40 years of age and has a significant socioeconomic impact. TBI results from the head impacting with an object or from acceleration/deceleration forces that produce vigorous movement of the brain within the skull, with the resultant mechanical forces potentially damaging neurones and blood vessels and causing irreversible, primary brain injury. Primary injury lead...

Magnetic Resonance Imaging to Assess Changes in Meniscus Vascularity

The menisci in the knee joint are important for normal functioning of the knee. Meniscus tears are amongst the commonest of injuries to the knee. The pattern and blood supply of the meniscus tears determines the treatment plan and outcome. The surgeon identifies the blood supply to the meniscus tear area during the arthroscopy(key hole operation) and decides the treatment option ie repair versus partial meniscectomy. This study aims to identify any changes that occur in the ...

Oxygen as a Limiting Factor for Performing Multitasking

The Brain uses 20% of the total oxygen supply consumed by the entire body. Even though, less than 10% of the brain is active at every given time, the brain utilizes almost all the oxygen delivered. In order to perform different tasks or more than one task (multi-tasking), the oxygen supply is shifted from one brain region to another, via modulation of blood perfusion. The aim of the present study was to evaluate whether hyperbaric oxygen (HBO) environment, with increased...

Erythropoietin in Traumatic Brain Injury (EPO-TBI)

Many people who have a traumatic brain injury (TBI) - usually from a blow to the head such as in a vehicle collision or in a fall do not survive or, if they do, suffer from long-term disability. Previous studies have shown that about 1,000 people in Australia and New Zealand suffer a moderate or severe TBI every year. With current best available treatment and therapies many of these patients sustain loss of brain function and long term disability in varying degrees. When...

Analysis of Brain Activity to Uncover Brain-behavior Relationships Related to Therapy Outcomes in Aphasia

Aphasia is a loss of language due to stroke or other brain injury. Word-finding in conversation is a universal and persistent difficulty in aphasia. While several techniques exist to improve word-finding in aphasia, it is unclear how the brain changes in response to behavioral therapy. In this study, persons with aphasia will receive behavioral therapy aimed at helping them to be more successful at finding words. Twenty therapy sessions will be provided in a 10-week period. Eac...

Cerebrovascular Outcomes in Ischemic Heart Disease

This project will examine the association between (cardio)vascular disease, blood supply to the brain, and cerebrovascular endothelial activation. Also, we will investigate the impact of exercise rehabilitation on brain vascularization, cerebrovascular endothelial function and blood flow control.

Innovative Approaches to Tuberculosis Control

This study is designed as a cluster-randomized trial. The cluster unit is at the community level. Communities will be randomized to 1 of 2 study arms: DOTS+ACF or DOTS. Communities in the DOTS+ACF arm will receive door-to-door symptom screening of the entire population by health care workers between 2 and 4 times over a 9-month period. Those communities in the DOTS-arm will receive the current standard of care in those communities (PCF). All study communities will be recei...

Effects of rTMS on Brain Activation in Aphasia

This study will investigate the use of repetitive transcranial magnetic stimulation (rTMS), a non-invasive brain stimulation method, to improve word-finding abilities in Veterans and non-Veterans with chronic language problems following stroke (aphasia). Improving word-finding is important because word-finding difficulties are among the most common and debilitating consequences of aphasia. Although rTMS has shown promise as a treatment approach, not all individuals with aphasia...

The SMARTChip Stroke Study

Stroke is one of the leading causes of death and disability in the UK and currently costs the country £7bn per year. There is an overwhelming need to accurately and rapidly triage patients to allow best use of finite NHS specialist resources for the treatment of stroke. A simple blood test of substances (the purines) that result from cellular metabolism and are produced in excess when brain cells are starved of oxygen and glucose (as occurs during a stroke) is proposed. The s...

Integrated Cervical Cancer Screening in Mayuge District Uganda (ASPIRE Mayuge)

The purpose of this pragmatic cluster randomized control trial is to test the effectiveness of cervical cancer screening follow-up completion using two implementation approaches for self-collected HPV testing in a rural, low-resource setting: 1) community health workers recruiting women door-to-door and 2) community health workers recruiting women at community health meetings. This study will also help to further understand how current patient referral systems are workin...

Study to Gain Insights in Treatment Patterns and Outcomes in Patients With Atherosclerosis Prescribed to Xarelto in Combination With Acetylsalicylic Acid

In this study researchers want to gain more information on treatment patterns of patients treated with Xarelto in combination with acetylsalicylic acid (ASA). Both drugs reduce the risk of blood clots via different pathways. The study will enroll adult patients suffering from coronary artery disease (narrowing or blockage of vessels that supply the heart with blood) or peripheral artery disease (narrowing or blockage of vessels that supply the legs or head with blood). The stud...

Modified Perfusion for Neonatal Aortic Arch Reconstruction

Even though the lower part of the body does receive some blood supply during Cardiopulmonary Bypass(CPB) surgery, it may not be enough. As a result of this lowered blood supply, there are complications associated with CPB and clamping of the aorta. These include complications with the stomach, intestines and kidneys. The hypotheses of this study are that increased lower body perfusion during aortic arch reconstruction will decrease intestinal ischemia and the incidence of nec...

Oxygen Therapy in Schizophrenia

Due to intense ATP-consuming processes in the brain, a high level of brain energy supply is required. A popular hypothesis regarding the pathogenesis and pathophysiology of schizophrenia postulates hypofunction of neuronal circuits in the prefrontal and limbic-temporal areas. An emerging body of data suggests that impaired energy metabolism due to mitochondrial dysfunction plays a role in the pathophysiology of schizophrenia. Under normal conditions cellular metabolic rate, i...

Ferumoxytol in Magnetic Resonance Imaging of Pediatric Patients With Brain Tumors

This phase II trial studies ferumoxytol in the magnetic resonance imaging of pediatric patients with brain tumors. Magnetic resonance imaging using ferumoxytol may help in viewing a brain tumor and blood vessels in and around the tumor in a different way than the standard gadolinium-based contrast agent. Imaging with this experimental contrast agent may give doctors more information about tumor blood supply and the extent of the tumor itself.
