Filter by:Transthyretin amyloidosis exhibits a variety of possible phenotypes, the hereditary neurological form being the most commonly found and studied (familial amyloidotic polyneuropathy or FAP), which can present from oligosymptomatic patients to patients with peripheral sensorimotor polyneuropathy of varying degrees and dysautonomia. Although a specific mutation usually causes a specific phenotype, that is, with a predominantly cardiac or preferential neurological profile, with the increase in the number of diagnosed cases, an overlapping of clinical presentations has been observed. The assessment of the autonomic profile in individuals with familial amyloidotic cardiomyopathy (FAC) has not been well studied, and it is not known whether patients with an exclusively cardiac profile of the disease may present dysautonomia or whether even mutation carriers without cardiac involvement may exhibit it. In this study, the autonomic profiles of patients with familial amyloidotic heart disease will be compared with the profiles of patients who have mutations but without established heart disease and healthy individuals (control group).
Rehabilitation technology is more and more implemented in conventional therapy to increase the dosage of therapy and/or increase patient's motivation towards therapy. In orthopedic as well as neurological rehabilitation it is important to exercise with enough intensity and repetitions to improve functional performance in activities of daily life, and consequently quality of life. At the moment, not all (rehabilitation) technologies are adapted towards the wishes and needs of both patients and therapists for everyday use in the clinical setting. Also, not all technologies are fit for independent use by the patients. Researcher of PXL have developed a Kinect-based system (i.e. i-ACT) for rehabilitation and performed supervised research with i-ACT in neurological and musculoskeletal rehabilitation, and older adults. Within this research, patients will exercise with i-ACT under supervision of their therapist during weekdays, but in the weekends they will be motivated by the medical staff to perform their exercises with i-ACT. The medical staff will be present for safety reasons, but the patient is asked to use and exercise with i-ACT as independent as possible. The aim of this research is to explore to which extend i-ACT is suitable for semi-independent use by patients in orthopedic or neurological rehabilitation.
EXSTATIC is a multicenter mixed methods convergent study exploring experiences and attitudes of ICU healthcare professionals caring of agitated traumatic brain injury (TBI) patients. The study aims to explore the experiences and attitudes of ICU nurses and other ICU healthcare professionals on the management of agitation in acute TBI patients. This project includes three qualitative methods and one quantitative method. First step consists in structured observations of the daily routine of ICU healthcare professionals when TBI patient admitted in the ICU develops agitation. This step will allow us to raise emerging research questions from the field and to develop subsequent steps. Secondly, we will conduct semi-structured interviews with ICU nurses. Themes emerged in the interviews are essential to understand nurses' experiences and attitudes towards TBI agitated patients and describe their relational role amongst patients, other professionals and families. A retrospective cohort of TBI patients gathered through medical files will follow aiming to document in which way observations in the two first phases are reflected in the clinical notes. Finally, different ICU healthcare professionals will be invited to participate in focus groups to identify further themes in semi-structured interviews in nurses, compare them and prioritize which are the most relevant to nurses experiences and which ones need to be addressed for their future practice. The integration of the different methods will be done using sequential steps of the research (the previous informing the next one) and by the integration of results for each step. Qualitative data will be evaluated following the grounded theory using thematic analysis. Quantitative data will be analysed using descriptive statistics. Qualitative and quantitative results will be combined in a convergent interactive interpretative design. Race and gender perspective will be integrated in collection, analysis and interpretation of data.
Freezing of gait (FOG) is a common and devastating symptom in advanced stage Parkinson's disease (PD), which contributes to falls and disability. Unfortunately, there is no effective pharmacological treatment for FOG. It is suggested that the cortex-basal ganglia circuit, especially the frontal lobe, plays an important role in the pathogenesis of FOG. Repetitive transcranial magnetic stimulation (rTMS) effects over the cortex and affects the subcortical neural circuits. Previous studies have demonstrated that rTMS can improve FOG for PD patients. In the present randomized controlled trial (RCT) study, the invastigators aim to investigate the efficiency of rTMS over different motor regions of frontal lobe. The efficacy of treatment is evaluated by the score of FOG questionnaire and FOG provoking test, and the changing of neural network shown by functional magnetic resonance imaging (FMRI). Then the effects of rTMS over different brain regions will be compared for choosing a better target. The study will provide the evidence for non-invasive neuro-modulation of Parkinson's disease with freezing of gait (PD-FOG).
Postoperative delirium is common after major surgery, and is associated with adverse outcomes. Systematic reviews and meta-analyses of randomized controlled trials have shown that perioperative administration of dexmedetomidine may decrease the incidence of postoperative delirium in patients after either cardiac or non-cardiac surgery. However, neurosurgical patients are often excluded in clinical trials of postoperative delirium. In this prospective, multicenter, randomized, double-blinded, and placebo-controlled trial with two parallel arms, ICU admitted adult patients after intracranial operation for brain tumor will be enrolled. Low-dose dexmedetomidine will be applied during the early postoperative phase. The investigators aim to evaluate the efficacy and safety of low-dose dexmedetomidine for prevention of postoperative delirium in this patient population. The primary hypothesis is that, compared to the placebo group, the prophylactic use of low-dose dexmedetomidine can decrease the incidence of postoperative delirium without significant adverse events in patients after intracranial operation for brain tumor.
In this trial, The investigators are going to investigate the improvement of neurological functions and infarced area of the brain in ischemic stroke patients after ingestion of omega 3 products that have high concentrations of DHA and EPA in comparison to control group. The study will assess the improvement by computerized calculation of the size of the infarcted area before and after the intervention and neurological assessment tools. The researchers will follow the scientific and ethical regulations prevent any harmful effect on recruited subjects.
The recent implementation of European Reference Networks for Rare Diseases (ERNs) is an unprecedented move to improve the care of patients suffering from rare health disorders by transnational collaboration. ERN-RND, the ERN for Rare Neurological Diseases, oversees more than 35,000 patients in 31 specialist centers in 13 countries. The ERN-RND registry aims to gather information on patient cohorts in the multiple specialist centers and to provide an overview on patient numbers principally accessible for translational studies.
Using a technique called adaptive optics imaging applied on retina, investigators aim to gain access to vascular changes that could occur early in the course of Multiple Sclerosis (MS) and which could reflect vascular changes occurring along the optic nerve of the brain parenchyma. Indeed, our team has been able to develop a quantitative method to measure the perivascular infiltrate in the retina of patients with various inflammatory retinal disease. It has been observed in MS patients that this perivascular infiltrate can also be detected in the retina. However, its distribution across MS phenotypes (relapsing or progressive MS, with and without optic neuritis) is still unknown.
