Filter by:1. The primary aim of this study is to investigate the correlation between the length of ICU stay and a newly developed FIVE score in neuro-intensive care patients. 2. The secondary objectives are to evaluate the impact of the FIVE score on hospital length of stay, Modified Rankin Scale, and mortality, as well as to determine the correlation between the GCS, FOUR, and FIVE scores
This pilot study in healthy volunteers aims to determine if biological sex has an impact on recovery from dexmedetomidine-induced unconsciousness, and if transcranial magnetic stimulation combined with electroencephalography (TMS-EEG) can be used to measure brain complexity during dexmedetomidine sedation without arousing study participants.
This behavioral study on healthy participants aims to provide a baseline reference for assessing alterations of decision-making performance in pathological conditions. To this purpose, this single center non-interventional behavioral study will assess the extent to which decision-making performance is affected by distinct experimental manipulations, as well as by ageing effects, in 200 healthy individuals. The main questions it aims to answer are: - to what extent is decision-making performance stable, within individuals, regardless of non-economic manipulations concerning stimuli perceptual features as well as type of processing and motor response required to participants? - are these manipulations additionally influenced by participants' age? Healthy participants will be recruited for distinct behavioral studies assessing the effects of the aforementioned manipulations of distinct metrics of decision-making performance, such as loss aversion, risk aversion, and delay discounting.
Determine the feasibility, practicality, and early efficacy of a TeleRehab program (ICARE) to improve outcomes for persons with traumatic brain injury (TBI) in recognizing and responding to others' emotions alongside their care partner (CP).
To examine the feasibility, acceptability, and preliminary efficacy of a remotely delivered intervention for civilians and service members with mild traumatic brain injury (mTBI) who have difficulty recognizing and regulating their emotions. Post-treatment outcomes of interest include emotional self-awareness and regulation, resiliency, and affective symptoms.
Introduction: A side-lying recovery position is recommended when victims are unresponsive but breathing normally and, hence, do not require cardiopulmonary resuscitation. In 2021, the European Resuscitation Council (ERC) and the Belgian Red Cross-Flanders issued new guidelines which included the description of a modified recovery position to avoid problems in victims with joint stiffness and to overcome potential obstructed venous return in the dependent arm. Based on good practice insights, the dependent arm will now be extended and not bent to support the other arm. However, there is currently no evidence available to support a specific recovery position. Objectives: The aim of this study is to assess the impact of different recovery positions on perfusion of the forearm and associated comfort. Methods: In this cross-over randomized controlled trial, 24 healthy volunteers will be placed in either the lateral recovery position with extended dependent arm or with bent arm, and in the other position thereafter. Before and between both recovery positions, the volunteers will be positioned supine for 15 min. Several perfusion indices of the forearm will be non-or mildly invasively monitored in the respective recovery positions by radial artery tonometry, ulnar artery echo doppler and venous congestion plethysmography. Subjective participant's discomfort and pain will be assessed as well. Differences in continuous outcomes between the different recovery positions will be assessed with paired t-tests or wilcoxon signed-rank test. Discussion: The benefit of lateral positioning of adults and children with decreased level of consciousness has been widely accepted despite limited supportive scientific evidence. We here will provide direct evidence (i) whether venous drainage in the dependent limb is impaired when positioning the victim in the lateral recovery position with bent arms and (ii) whether this potential complication can be minimized by extending the dependent arm. The major limitations of this study is that healthy volunteers, instead of non-responsive victims, are included as participants, and that the study will be performed in a highly controlled environment. Nevertheless, the generated insights will directly fuel evidence-based treatment recommendations regarding the recovery position in first aid settings, and fill a current gap in evidence.
The goal of this observational study is to examine the clinical presentations, the diagnostic tests performed and the management of patients presenting with transient loss of consciousness (TLOC) The main questions it aims to answer are: - prevalence of TLOC - prevalence of different diagnoses leading to TLOC Demographic, clinical, paraclinical and biological data will be collected from the emergency medical file
The effect of intravenous lidocaine on ED50 and ED95 of propofol, which causes unconsciousness, is unclear. In addition, it is not clear whether the depth of anesthesia induced by propofol changes when lidocaine is used in combination. Therefore, the purpose of this study was to study the effects of intravenous lidocaine on ED50, ED95 and NTI values of propofol induced unconsciousness .
Prospective multi centre cohort study examining the clinical presentation, diagnostic tests, and management of adult Emergency Department (ED) patients presenting with Transient Loss of Consciousness (TLOC) either undifferentiated or thought to be of syncopal origin.
PURPOSE: The aim of this study is to investigate the effect of early coma arousal therapy on conscious level and cognitive function in sever traumatic brain injury patients. BACKGROUND: Traumatic brain injury (TBI) could be simply defined as an alteration in brain function due to external forces and is considered as one of the leading cause of death and disability worldwide, especially among young adults and the elderly. Current estimates imply that annual incidence of TBI is 50-60 million worldwide, and specifically for Europe and USA, 0.5% of Europeans and 1.1% of Americans are experiencing a TBI each year. The original scale has since been revised and is known as the Rancho Los Amigos Revised Scale (RLAS-R). One of the limitations of the original eight level scale was that it did not accurately reflect the individuals with higher levels of recovery. Two more levels were added to the initial eight level Ranchos Scale to create a more comprehensive ten level scale named the Rancho Los Amigos Revised Scale (RLAS-R).
