Evaluation of Neuronal Damage in Patients Undergoing Robot-assisted Laparoscopic Radical Prostatectomy With Biomarkers

Robotic assisted laparoscopic surgery has become an alternative to open or laparoscopic technique in various surgical fields. Robot assisted laparoscopic surgery is preferred by surgeons and patients due to easy accessibility, lower blood loss and lower transfusion rates. However, robotic assisted laparoscopic surgery can cause significant changes in cardiovascular, respiratory, metabolic and cerebral physiology because it requires a deep trendy position. When long -lasting deep trendelenburg position is applied, the cerebral autoregulation is impaired. In the literature, the presence of cases with brain edema is shown. In recent years, many biomarkers have been used in the evaluation of brain damage. S100 Calcium Binding Protein (S100β), N Ron specific enolase (NSE), Glial Fibrils are among the biomarkers used to show acidic protein (GFAP) brain damage. The S100β is specific and is mainly produced by astrocytes and enters the bloodstream after neuron damage. Glial fibrils is an acidic protein (GFAP), a protein encoded by the GFAP gene in humans, an intermediate filament protein produced in the central nervous system. Neuron specific enolase (NSE) is one of the enzymes that increase brain damage encoded by Enolase 2 (ENO2) gene. Mini Mental State Examination and Montreal Cognitive Assessment will be performed to determine neurological changes developing in patients. The purpose of this study; Robotic assisted laparoscopic surgery is to examine the brain damage that may develop in patients due to deep trendelenburg position in patients with the said biomarkers and to evaluate the anesthesia methods applied in these surgery in line with the study results.

Study of Morphological, Spectral and Metabolic Manifestations of Neurological Complications in Covid-19 Patients

Viral pandemics, such as HIV and SARS-Cov-V1, have shown that they can lead to acute and / or delayed neurological complications. At the actual context of the pandemic Coronavirus disease 2019 (COVID-19), neurological manifestations seem to be confirmed since in 85% of COVID-19 patients, present neurological symptoms, including anosmia, ageusia, periorbital pain, dizziness, fatigue, even moderate headache, moderate memory and/or behavioral disorders. However, these neurological manifestations are not well studied and their radiological features are not well described. It is therefore important to assess these potential neurological complications in COVID-19 patients. To the investigator knowledge, there is no previous study in the literature describing spectral brain changes in COVID + patients. Thus, the goal of this work is to describe the radiological semiology using MRI and particularly Magnetic Resonance Spectroscopic (MRS) biomarkers in the evaluation of acute and / or delayed brain damage in COVID + patients presenting a neurological manifestations that are initially related to the cranial nerves damage.

Early Intervention Based on Neonatal Crawling in Very Premature Infants at Risk For Neurodevelopmental Disorder

Extreme prematurity is constantly increasing according to the World Health Organization. However, methods to train premature infants at risk of disability is sorely lacking. The goal of this project is to overcome this problem. In previous studies, the investigators discovered that promoting the crawling of typical newborns on a mini skateboard, the Crawliskate (a new tool that the investigators designed and patented EP2974624A1), is an excellent way to stimulate infants' motor and locomotor development. This method is a promising way to provide early interventions in infants at heightened risk for developmental delay, such as premature infants. The specific objective of this study is to determine if early training in crawling on this mini skateboard will accelerate motor (particularly locomotor) and/or neuropsychological development in very premature infants identified as high risk for developmental delay. Methodology: The investigators will study and follow two groups of very premature infants born between 24 and 26 weeks of gestational age or born between 26 and 32 with major brain lesions. These infants will be recruited before their hospital discharge at the NICU. After their discharge from the hospital, one group of infants will be trained at home by their parents under the supervision of physiotherapists to crawl on the Crawliskate every day for 2 months (Crawli group), and one group of infants will receive regular medical care (Control group). All infants will be tested for: 1)their crawling proficiency on the Crawliskate at term-equivalent age (just before training for the trained groups) and at 2 and 6 months corrected age (CA, i.e., age determined from the date on which they should have been born), 2) their motor proficiency between 2 and 12 months CA (2D and 3D recording of head control, sitting, crawling, stepping, walking) and 3) their neurodevelopmental, motor and neuropsychological development between 0 and 28 months CA: BSID III edition, ASQ-3, Amiel-Tison's Neurological Assessment, Prechtl Assessment of general movements. One more ASQ-3 questionnaire will be provided at five years. Expected results: The first research hypothesis is that premature infants trained daily to crawl (for two months after discharge from the NICU) will acquire proficient crawling patterns and develop earlier and more effective motor and neuropsychological development than premature infants who receive no training.
