Filter by:The incidence of postoperative cognitive dysfunction (POCD) is high and POCD affect the life quality and the prognosis of patients. Geriatrics is the independent risk factor of POCD, and POCD is also correlated with many other factors such as type of surgery, the duration of anesthesia and the anesthesia drugs used et al. So, the prevention and treatment of POCD in geriatrics is important. Dexmedetomidine is found to have the effect of neuro-protection, but it is controversy whether Dexmedetomidine has the effect of neuro-protection in geriatrics, especially the prolonged surgery. The purpose of this study is to explore the effect of Dexmedetomidine to the cognitive function at prolonged surgery in geriatrics in geriatrics.
There is a lack of evidence about the best method to involve the patient and population (IPP) into clinical practice guidelines (CPG) development. The goal of this pilot study is to document the acceptability, feasibility and effectiveness of two methods for the implication of patients with a traumatic brain injury (TBI) in CPG development. Method: A single blind, randomized crossover trial will be performed with patients having a TBI. Participants: A convenience sample of 20 patients a) with a moderate-to-severe TBI (Glascow Coma Scale <13), b) living with a TBI for two to four years, c) French-speaking, d) able to use a computer and e) able to participate in a two-hour group meeting will be recruited among the members of the Associations TCC Des Deux Rives. Procedures: The patients will first receive a in-person training on guidelines and IPP. They will be randomized into Group 1 or Group 2 by a researcher blinded to experimentation. They will experiment either group discussion (control intervention) or a Wiki (experimental intervention). Phase 1: A week after the training, Group 1 participants will be invited to a discussion group animated by an experimented moderator, where they will be asked to discuss a CPG recommendation chosen by the research team in an existing CPG. The participants will be asked : 1) about their opinion of the recommendation; 2) if they have a preference in regard to the recommendation ; 3) if they have some modification, correction or addition to bring to this recommendation. In the mean time, Group 2 participants will receive an email presenting a link to a Wiki. They will be invited to answer the same three questions as Group 1, but using a Wiki platform. The patients will have a week to interact and answer the questions; recalls could be sent by email if required. At the end of Phase 1, participants of both groups will fill a questionnaire documenting the acceptability of the method experimented. Phase 2: As per the crossover design, the Group 1 participants will then be assigned to the Wiki intervention and the Group 2 participants will be assigned to the discussion group intervention. The procedure will be repeated with a second recommendation. At the end of Phase 2, the patients will be asked to answer a short survey to validate their preferences about the two methods. Tools: The acceptability of the methods will be evaluated with a questionnaire adapted from Sidani and al. and validated with three TBI individuals. The feasibility of the intervention will be evaluated using a) the number of participants who reached the group or the Wiki, b) the number of participants who completed the intervention c) the number of support interventions required in the group and in the Wiki. The effectiveness of the two methods will be evaluated by submitting the adapted recommendations to a panel of expert clinicians evaluators blinded to the methodologies of recommendations adaptation. They will be invited to rate the clarity, accuracy, appropriateness and usefulness of the recommendations. Analysis: Feasibility indicators will be reported using descriptive statistics. Within-subject analysis using non-parametric statistics will be performed to assess the acceptability of the two methods. AC1 coefficient of raters' agreement will be calculated on the expert evaluation scores, and the effectiveness of the methods will be compared using appropriate non parametric statistics to. Impact: This pilot trial will be the first one to evaluate methodologies for involving disabled individuals into CPG development.
Balance control is the sum action of the sense and reaction systems. In order to perform different activities in different postures one must have the ability to control and to adjust his balance in different conditions.A deficit in brain action following injury, disease or aging can undermine the ability to control balance and increase the risk to fall.The limitation in gait and mobility can increase morbidity. There is a limited number of tools evaluating and recording balance control ability. Most of this tools are observational and can be used in the clinical field. The aim of this work is to estimate the feasibility of an objective tool that can evaluate balance by tracking objective quantitative measures during the standard physical therapy session without using an expensive equipment. By using this tool the therapist can monitor the patient and collect quantitive data while performing tasks while keeping balance. This tool will allow the therapist to detect changes in balance and evaluate the effect of different conditions on the patients balance. This tool is based on the well known functional reach test. The addition of this tool to the test is the use of a simple camera and a computer softwear that will collect the data and analyze it while performing the test. This tool will give the therapist information on the responsiveness and the spatiotemporal measures of the performance. The aim of this work is to check what is the contribution of spatiotemporal measures of the functional reach test among patients suffering from acquired brain injury to the understanding of the motor function and balance control of people suffering from brain injury. .
