Filter by:The goal of the project is to describe novel factors affecting outcome after elbow fracture surgery with an in-depth evaluation of the role played by neuro inflammation from concomitant peripheral nerve injury or head injury in elbow fracture outcomes. Among all upper limb fractures, elbow trauma is the most frequently associated with a severe impact on patient function and quality of life. One of the main reasons for poor outcomes is the complexity of the elbow joint, which involves three bones and two planes of motion, essential to position the hand in space. The flexion extension axis is crucial for eating and hygiene, while forearm pro-supination is mandatory for most professions, from office work to manual labour.
The investigator hypothesizes that oxidative stress responses to West Nile virus infection in the central nervous system determine the severity of infection and the long-term neurological, neuropsychological and functional sequelae of West Nile Neuroinvasive Disease.
Little is known about the exact role of feedback in cortical processing. Hypotheses on its function range from attentional control to the transmission of Bayesian priors in the interpretation of sensory events, such as in the theory of Predictive Coding. Recent advances in identification of functional signatures of feedback and feedforward signal, as well as additional techniques based on causal relations in signal processing open a unique methodology for probing such processes in awake and behaving organisms and testing these theories and more generally the hierarchical processing between cortical areas. The objective of this project is to study feedback and feedforward relations and localization in the well established pathways between cortical areas V1 and Medial Temporal (MT) that have been implicated in early integration processes in motion perception.
In this prospective randomized controlled multi center trial the investigators stratify "Very Low Birthweight " (VLBW)-infants with growth retardation in small for gestational age (SGA) or intrauterine growth restricted (IUGR) - infants and aim to investigate the impact of a nutritional management with enhanced nutrients from discharge up to the 52nd week of postconceptional age on growth, body composition, metabolic programming, metabolomics, microbiome and long term neurodevelopmental outcome. In this study, the investigators will evaluate the difference in metabolic profiles of SGA and IUGR preterm infants. The investigators will further longitudinally assess, how different nutritional interventions affect the altered pathways in the first year of life and identify, in combination with data available from metabolic markers, microbiome and breast milk analysis, potential pathways resulting in increased disease risk later in life.
The social, psychological, economic burden of Spinal trauma with deficit is great, and there is no curative treatment. Erythropoetin (EPO) is promising, due to its neuroprotective effects demonstrated in vitro, in vivo in animal models and in a preliminary study including patients with stroke. The study primary end point is to find out the maximum tolerated dose of EPO. This is based on the occurrence of pulmonary embolism during a 14 day delay following EPO injection. Secondary end points include comparisons of EPO kinetics in blood and cerebrospinal fluid (CSF), study of EPO effects on several inflammatory and apoptotic bio markers and blood cell counts. The experimental design is a dose scale study (600 to 2400 UI/Kg), using a single dose of rHuEPO, (EPREX®). The EPO dose is defined using a Bayesian continuous reassessment Method (CRM). The sample size is expected for less than 20 patients. Eligible patients are patients aged 15 to 65 years, able to receive the EPO injection within 12 hours of a spinal trauma, without vital blood loss or associated diseases. The follow-up lasts 6 months.
