Filter by:Cervical spinal cord stimulation can elicit arm and hand movements through recruitment of proprioceptive neurons in the dorsal roots. In participants with cervical spinal cord injury, the spare roots bellow the lesion can be used to reactivate motor function. Decoding of motor intentions can be achieved through implantable electrocorticography (ECoG) devices. In this study, the investigators will use an investigational system using ECoG signal recording over the motor cortex to drive muscle specific electrical epidural spinal cord stimulation (EES). The investigators will assess the safety and preliminary efficacy of this system in 3 participants.
This study is a prospective two-arm, single blind randomized controlled trial design to compare the clinical effectiveness of telemedicine-delivered, 6-session, standardized cognitive behavioral therapy for insomnia (CBT-I) and mindfulness-based treatment for insomnia (MBTI) in treating insomnia symptoms and ameliorating depressive symptoms in persons with mild to moderate TBI and comorbid Post-Traumatic Stress Symptoms (PTSS) and insomnia symptoms in a 360 patients. Participants will undergo assessment (psychosocial questionnaires, neurocognitive testing, sleep monitoring) at baseline, at the end of treatment, and at 6- and 12-weeks post-treatment. The primary outcome is sleep as measured by the Insomnia Severity Index (ISI).
The purpose of this study was to quantify overall blood flow and renal cortical perfusion in patients with septic acute kidney injury (AKI) using ultrasound (US) Doppler and contrast-enhanced ultrasound (CEUS).
The investigators aim to evaluate the fixation of the ankle syndesmosis in appropriate ankle fractures with bioabsorbable screws. Ankle fractures are common, and a proportion of them involve both fracture of the bone and also disruption of the syndesmosis, a strong ligamentous complex connecting the distal fibula and tibia. If left without fixation this causes a high incidence of pain and early arthritis. The most common technique for fixation of this syndesmosis involves the use of the same type of metal screws used to fix the fractured bones. As the syndesmosis permits small degrees of movement in normal subjects, fixation of this with metal usually leads to screw breakage and, or pain. It is common practice to remove these screws after a period of time once the syndesmosis has healed in the correct position. Bioabsorbable screws have the advantage of allowing small increments of movement, and also resorb naturally therefore do not have to be removed with a second surgical procedure. They are used in other centres worldwide, and the investigators therefore seek to evaluate syndesmosis fixation with them in their unit. The investigators would aim to recruit patients who have a syndesmotic injury requiring fixation, and who can consent to participating. They would undergo an identical surgical procedure to the standard current practice, apart from using a bioabsorbable screw in exchange for the metallic screw for syndesmosis fixation. All other components would remain unchanged, as would post operative protocol and management. To evaluate the fixation the investigators would use a limited CT scan (equivalent of about 3 months background radiation) after the time of fixation and at one year. This will help to assess the maintenance of reduction of the syndesmosis with time. The investigators would also assess patient reported outcome measures and pain scores, length of procedure and intraoperative radiation levels, weight bearing distribution tests, as well as any complication that may arise.
As a simple auxiliary tool for lower extremity orthopedic surgery, tourniquet can effectively reduce intraoperative bleeding and ensure the clarity of the operative field, effectively shorten the operation time and improve the operation efficiency. The extensive use of tourniquets in lower extremity surgery will not only cause local paralysis, pain and other complications, but also bring about postoperative complications such as large drainage volume and deep vein thrombosis. Recent studies have found that tourniquet induced ischemia-reperfusion injury not only affects the local tissue structure and function of skeletal muscle, but also causes reperfusion injury in distant organs (such as heart, lung and brain). Therefore, improving tourniquet ischemia-reperfusion injury after knee replacement is of great significance to improve the quality of life of patients during the perioperative period. Therefore, the aim of this study was to investigate the effects of dexmedetomidine and tourniquet pretreatment on myocardial injury and brain injury caused by lower extremity ischemia-reperfusion.
The study aims to identify the preoperative parameters associated with the risk of postoperative acute kidney injury (in particular the parameters of the SPARK score) in patients of the Besançon University Hospital who have undergone digestive or vascular surgery.
Acute kidney injury (AKI) is a frequent disease in conventional hospital departments and in intensive care units. It's associated with a high risk to develop chronic kidney disease (CKD), even after a single small AKI episode. It's also associated with an important morbi-mortality, particularly cardiovascular (CV). Some studies have already showed a link between AKI and CV risk but pathologic mechanisms implicated are still unknown. In AKI and CKD, numerous substances, called uremic toxins (UT) are accumulating in blood. In CKD, those toxins, and particularly Indoxyl sulfate (IS), are known to have cardiac and vascular deleterious consequences. However, in AKI, whether acute accumulation of UT may trigger CV complications is unknown. The purpose of this study is that during AKI, a high UT concentration, in particular IS, would be associated with early vascular and cardiac dysfunctions that can be characterized by the persistence of an accelerated pulse wave velocity (PWV). The main objective is to evaluate the correlation between UT concentrations (especially IS) and arterial stiffness (PWV measurement) at three months of an AKI episode in conventional hospital departments and in the intensive care unit of nephrology.
Nonsuicidal self-injury (NSSI) is defined as the direct, deliberate destruction of one's own body tissue without suicidal intent, typically including behaviors such as cutting, burning, or hitting oneself. The risk of engaging in NSSI is particularly high during adolescence. NSSI is associated with impairments in emotion regulation and NSSI behavior serves as an attempt to regulate emotion. We propose to examine whether training adolescents with NSSI to self-regulate using emotion regulation skills to down-regulate hemodynamic activity of the salience network, involved in emotional processing. Moreover, we propose to examine whether limbic-prefrontal cortex connectivity can be increased following neurofeedback, thereby helping adolescents find an optimal way to emotionally regulate with the help of neurofeedback, instead of engaging in NSSI to regulate emotions. We also aim to examine effects of real-time biofeedback by investigating if adolescents can regulate their psychophysiological activity during emotional reactivity with biofeedback. Sixty participants with NSSI will be recruited and offered either real-time functional magnetic resonance imaging (rt-fMRI-NF) (n = 30) or real-time biofeedback (n = 30) training. Participants each each condition will then be randomized to either an active or a control condition (n = 15/group). Participants will take part in three runs of feedback training. Changes in emotional reactivity as measured with facial electromyography (EMG) before and after feedback training will be the proximal outcome measure together with changes of the blood oxygenation level dependent (BOLD) response during real-time fMRI-neurofeedback for the neurofeedback training. Proximal outcome measures for the biofeedback will include psychophysiological measures of emotional reactivity (facialEMG). More distal outcome measures for both neuro- and biofeedback will be measures of NSSI: frequency, methods and severity as well as self-report measures of difficulties with regulating emotions, emotional reactivity and psychiatric symptoms.
The goal of this study is to assess the feasibility of recruitment, and barriers to delivery of an enhanced rehabilitation service, in patients surviving major trauma. The main questions it aims to answer are: are the investigators able to recruit patients to a research study are the investigators able to retain patients in the research study are the investigators able to identify appropriate primary outcome measures are the investigators able to identify barriers to future large-scale definitive trial or service delivery Participants will would be offered at least two sessions of the Enhanced Rehabilitation Programme (ERP), each lasting 60-120 minutes per week, delivered in the Manchester Institute of Health and Performance (MIHP). Participants not willing to travel to the MIHP, or declining to engage in the ERP, will be asked to join the Standard Care (SC) group. This group will provide questionnaire data and clinical outcome measure collection with their usual place of therapy. Researchers will compare the ERP group and the SC groups to assess any additional benefits to the ERP.
