Filter by:The present study is an explorative analysis of the relationship between cerebral blood perfusion and oxygenation and lung mechanical variables at different ventilator settings. It is a safety study excluding patients with severe lung injury or brain edema.
The specific aims of the proposed study are to evaluate: 1) the feasibility of design elements of a Strength and Awareness in Action: an Intervention for Post-Acute TBI Headaches (SAA-TBI) intervention trial (e.g., an exercise run-in to facilitate participant retention); 2) yoga instructor fidelity; and 3) variability estimates for candidate proximal and distal outcomes. Performance of validated measures, including those associated with quality of life, as well as data collected via ecological momentary assessment and pedometry (physical activity) will be evaluated.
This is a follow-up study for an ongoing open label trial conducted by the Sheppard Pratt-Lieber Research Institute utilizing the catechol-O-methyl-transferase (COMT) inhibitor Tolcapone to evaluate its effects on cognition and neuropsychiatric symptoms in patients with brain injuries (BI). In this study, investigators will conduct a double-blind, placebo-controlled clinical trial utilizing a crossover design to study the effects of two weeks of Tolcapone 200mg administered three times a day (total of 600mg/day) on cognitive performance. Physical, emotional, cognitive and social functioning will also be evaluated through participant and proxy report. The investigators are planning to randomize a total of 12 patients with a history of acquired brain injury (BI).
Background: Central Venous catheter insertion technique and indwelling time are major risk factors for CVC colonisation. Colonisation occurs through microbial migration and biofilm formation along the catheter insertion tract. This study set out to determine the prevalence and associated factors for central venous catheter colonisation among critically ill patient. No data exists in this clinical setting addressing this topic. Methods: The study population included 100 participants with central venous catheters in situ for at least 24 hours. Catheter tip (distal 5-cm segment) and blood cultures (10mls peripheral blood) were obtained at the time of catheter removal.
Introduction: In the recent past, medical training systems using virtual reality (VR) have been introduced to neurorehabilitation to train motor function deficits in patients. The usage of VR-based training systems is based on the evidence of neuroplasticity, which is responsible for recovery of patients suffering from motor dysfunction. Such systems are increasingly used to encourage purposeful limb movements in a VR environment and its efficacy has been found comparable with conventional therapeutic intervention. VR training systems, e.g. the YouGrabber® (YG), will increasingly also be used at home. Therefore, it is essential to integrate valid and reliable assessment tools to monitor the recovery process. Objectives: The aim of the clinical study is to evaluate the usability, feasibility and validity of the digital version of the ActionResearchArmTest (d-ARAT) using the YG system as a platform. Additionally, the feasibility and usability of the implementation of two rehabilitation measures that only recently became integral part of neurorehabilitation, e.g. Action Observation (AO) and Motor Imagery (MI), into the YG training software will be evaluated. Patients & methods: This observational study is designed as a single-arm trial for testing the assessment software including pre- to post rehabilitation comparison of a training involving AO and MI. Therefore, 75 adult patients with Parkinson's disease, MS, Stroke, traumatic brain injury or Guillain-Barré syndrome will be included. 30 out of the 75 patients will take part in the 4-week training on the enhanced VR-based system with a total of 16 training sessions of 45 min each. Primary outcomes will be the score on the System Usability Scale (SUS) and the ARAT as well as the d-ARAT scores. Secondary outcomes will be hand dexterity (Box-and-Block Test), upper limb activities of daily living (CAHAI) and quality of life (EQ-5D-5L). Hypothesis: The study was designed to evaluate the d-ARAT and the training software modules for the YG system. Currently AO and MI specific tasks are being integrated and the ARAT subscales will be implemented on the basis of the redesigned glove equipped with new sensors. The results are expected to give recommendations for necessary modifications. They might also contribute knowledge concerning the application of AO and MI tasks within VR training.
The primary objective of this study is to assess the incidence of VAP in patients with TBI and to identify risk factors for developing VAP in this specific patient population (types of co-injuries in patients with multiple trauma or characteristics on admission). The secondary objective is to assess the prevalence of pathogens responsible for early- and late-onset VAP in patients with TBI. The tertiary objective is to discuss the ability of preventive measures to reduce the incidence of VAP
mTBI is widely recognized as a major public health concern in the United States and worldwide. mTBI diagnosis remains a clinical challenge as no single test can diagnose every concussion. Recent advances in EEG evoked response potential analysis have led to a novel technique for assessing brain network activation (BNA) patterns. This study purpose is to study this BNA technology in individuals who have sustained a concussion.
The purpose of this clinical trial is to assess the relative efficacy of two non-pharmacological interventions for insomnia in Veterans suffering from chronic mild traumatic brain injury (mTBI).
This study will evaluate the changes in respiratory mechanics following traumatic brain injury and determine the effect of inhaled nitric oxide on gas exchange.
Most trauma deaths are related to traumatic brain injury (TBI). Although the management of patients has improved, mortality remains unacceptably high, and half of survivors of moderate and severe TBI are left with major functional impairment. Current management guidelines are based on limited evidence and practice is highly variable. Most acutely ill patients with TBI will develop anemia, which may decrease oxygen delivery to a fragile brain. While clinical practice is moving towards transfusing at low hemoglobin (Hb) levels, experts have expressed concerns regarding restrictive strategies, which may adversely affect clinical outcomes in TBI. Our primary objective is to evaluate the effect of red blood cell (RBC) transfusion thresholds on neurological functional outcome. We hypothesize that a liberal transfusion strategy improves outcomes compared to a restrictive strategy.
