abstract: Cerebral palsy (CP) is a non-progressive neurologic disorder characterized by motor pathway damage prior to functional development. Damage to the central nervous system impairs motor functioning, including control of motor movement, loss of coordination, and loss of purposeful posture in individuals with cerebral palsy. This creates abnormal walking gait, impaired balance, and loss of muscle control. Current research shows positive results in studying the use of rhythmic music and walking gait for individuals with neurologic disorders. However, most research focuses on neurologic disorders acquired later in life, such as post-stroke patients and individuals with Parkinson's disease and traumatic brain injuries. The current study addresses the impact of rhythmic music on walking gait for an individual with cerebral palsy. Research addresses whether the use of rhythmic music impacts: (a) endurance (laps, distance traversed, and steps taken) (b) cadence (steps per minute), (c) velocity (distance over time), (d) emotional responsiveness (positive or negative affect), and (e) motivation. The current study is a single subject, mixed method design under randomized treatment conditions. The subject is a 25-year-old female diagnosed with spastic diplegic cerebral palsy. The subject participated in a five-week study, three times a week for one hour each session. Assessment was conducted during the first session. The following 14 sessions included gait training either under treatment (the use of recorded rhythmic music accompanied by audible drum beat) or control (no music) randomly assigned prior to the beginning of the study. Data were collected through video recordings, subject and researcher journals, and emotional responsiveness surveys. Data were analyzed for treatment versus control conditions. Analysis of both quantitative and qualitative data indicated that rhythmic music does impact walking gait for individuals with cerebral palsy. When compared to control conditions, the treatment conditions showed an increase in endurance, cadence, and velocity, and improvement in affect and motivation. / Dissertation/Thesis / M.M.

Objectives. Acute flaccid paralysis (AFP) has recently emerged as a major central nervous system complication associated with West Nile virus (WNV) infection. The spectrum of clinical presentations of AFP in WNV infection and its sequelae have not been well-studied. Methods. We describe three patients with AFP due to WNV infection and review the clinical presentations of 56 patients with this complication derived from published studies. Results. Patients with AFP and WNV presented with a spectrum of illness ranging from single extremity paralysis to quadriparalysis with cranial nerve involvement. Patients commonly developed respiratory failure (54%) and bladder dysfunction (22%). While fever was nearly universal (92%), signs of meningismus were less common (17%). Cerebrospinal fluid (CSF) analysis generally revealed a modest pleocytosis, and imaging studies were not diagnositic. Persistent neurologic impairment occurred in all survivors; overall mortality rate was high (22%) and was associated with both the extent of paralysis and advanced age. Conclusion. AFP in the setting of WNV is associated with significant mortality and long-term morbidity.

Author: Bc. Alice Pernicová Title: Motor and cognitive consequences of hypoxic-ischemic damage Objectives: The aim of this diploma work was asses the impact of Enriched Environment on development of rats after hypoxic-ischemic damage. Methods: Experiment was performed in 30 Long Evans rats from breeding in Institute of Physiology, Academy of Sciences of the Czech Republic. All rats were operated for dissection of carotid. Than randomly were half of rats chosen for hypoxic-ischemic damage. Group with hypoxic-ischemic damage were divided into control and experimental group, same procedure was with rats without HIE. For one week were rats from experimental group in special Enriched Environment cage, than they were split into smaller cages with Enriched Environment. Rats from control groups were in normal cages without special equipment. After defined time were all rats tested by chosen test: Reaching test, Ladder rung walking test, Bar holding test, Rotarod test, Morris water maze test, Open filed test. For data analysis were used Microsoft Excel 365, Sigma plot. Results: Results of test showed, that Enriched Environment can positively enhance motoric and cognitive deficit in rat development with hypoxic-ischemic damage. But it is obvious, that Enriched Environment can positively enhance development...

INTRODUÇÃO: Houve uma epidemia de infecção pelo vírus Zika (ZIKV) no Brasil, entre 2015 e 2016, que refletiu no aumento de casos de microcefalia neonatal secundária à infecção congênita pelo ZIKV. Para compreensão do padrão de acometimento neurológico dessas crianças foi realizado um projeto de pesquisa pelo Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP-USP), conhecido como ZIG, e realizado seguimento neurológico desses pacientes por meio do Exame Neurológico de Hammersmith Neonatal (HINE-N). OBJETIVOS: Avaliar pacientes com microcefalia secundária à infecção congênita pelo ZIKV por meio do HINE- N, descrever as características clínicas e de neuroimagem dos pacientes estudados e identificar fatores pré-natais, perinatais e demográficos potencialmente relacionados ao grau de comprometimento do exame neurológico. METODOLOGIA: O presente estudo faz parte do Núcleo de Estudos sobre Infecção Materna, Perinatal e Infantil (NEIMPI) do HCFMRP-USP e trata-se de um estudo não experimental, transversal, com intuito de correlacionar variáveis qualitativas e quantitativas. Participaram do estudo crianças com microcefalia secundária à infecção congênita pelo ZKV nascidas no município de Ribeirão Preto e seu Departamento Regional de Saúde (DRS XIII), no período de outubro de 2015 a dezembro de 2016. Os dados foram coletados no período de outubro de 2015 a janeiro de 2017. Realizou-se avaliação do perímetro craniano (PC), aplicação do HINE e coleta de dados em prontuário. Os dados foram processados e analisados com a utilização do Pacote Estatístico Statistical Package for the Social Sciences (SPSS), versão 22.0. RESULTADOS: Foram avaliadas 18 crianças, sendo predomínio do sexo feminino (55,6%), nascidas a termo, com exceção de uma que nasceu com 32 semanas, maioria originária de Ribeirão Preto (66,7%), via de parto normal (72,2%), ocorrido no Centro Obstétrico do HCFMRP - USP (83,3%), todas as crianças tiveram APGAR maior que 7. O peso de nascimento foi entre 1228 e 3200 gramas, com PC entre 26 e 31,5 cm. 72,2% das crianças fizeram ultrassom transfontanela e 100% fizeram ressonância magnética de encéfalo, com associação entre os resultados encontrados neles (ambos com p<ou=0,001). O score HINE-N foi baixo, porém não foram encontradas associações entre o score e as variáveis clínicas (ambos com p>0,05). Evidenciou-se associação entre a realização de pré-natal e a cidade de residência, local de nascimento, diagnóstico de microcefalia e de infecção pelo ZIKV no pré-natal, tipo de parto (p< ou = 0,001). A medida do PC apresentou associação direta com a presença de crise convulsiva (p<0,05) e houve associação entre crise convulsiva, ventriculomegalia e calcificação (p< ou= 0,001). CONCLUSÃO: O padrão de acometimento neurológico das crianças com microcefalia secundária à infecção congênita pelo ZIKV é muito severo, com presença de sinais precoces de paralisia cerebral desde o exame neonatal. Este estudo sugere seguimento prospectivo desses pacientes para melhor avaliação prognóstica e associação do score HINE com condições clínicas pré e perinatais / INTRODUCTION: There was an epidemic of Zika virus infection (ZIKV) in Brazil between 2015 and 2016, which reflected the increase in cases of neonatal microcephaly secondary to congenital ZIKV infection. A study was carried out for the Hospital das Clínicas of the University of São Paulo at Ribeirão Preto Medical School (HCFMRP-USP), and the followup of these patients was performed using the Neonatal Hammersmith Neurological Exam (HINE-N) aiming to understand the neurological involvement pattern of these children. OBJECTIVES: To evaluate patients with microcephaly secondary to ZIKV congenital infection using HINE-N, to describe the clinical and neuroimaging characteristics of the patients studied, and to identify prenatal, perinatal and demographic factors potentially related to the degree of impairment of neurological examination. METHODOLOGY: This study is part of the Center for Studies on Maternal, Perinatal and Child Infection (NEIMPI) of the HCFMRP-USP. It is a non-experimental, cross-sectional study aimed at correlating qualitative and quantitative variables. Children with microcephaly secondary to congenital ZKV infection born in the city of Ribeirão Preto and its Regional Health Department (DRS XIII), from October 2015 to December 2016, participated in the study. Data were collected in the period of October 2015 to January 2017. An evaluation of the cranial perimeter (PC), the application of HINE and data collection in medical records were performed. Data were processed and analyzed using the Statistical Package for Social Statistical Package (SPSS), version 22.0. RESULTS: A total of 18 children were evaluated, being 55,6% female, all to term with the exception of one who was born at 32 weeks, most of them from Ribeirão Preto (66.7%), normal delivery (72.2%), occurred in the Obstetric Center of the HCFMRP - USP (83.3%), all children had APGAR greater than 7. The birth weight was between 1228 and 3200 grams, with PC between 26 and 31.5 cm. 72.2% of the children had transfontanel ultrasonography and 100% had brain magnetic resonance imaging, with an association between the results found in them (both with p <or = 0.001). The HINE-N score was low, but no associations were found between the score and the clinical variables (both with p> 0.05). It was evidenced an association between prenatal and city of residence, place of birth, diagnosis of microcephaly and ZIKV infection in the prenatal period, type of delivery (p <or = 0.001). The PC measurement presented a direct association with the presence of seizures (p <0.05) and there was an association between seizure, ventriculomegaly and calcification (p <or = 0.001). CONCLUSION: The pattern of neurological involvement of children with microcephaly secondary to congenital ZIKV infection is very severe, with early signs of cerebral palsy since the neonatal examination. This study suggests a prospective follow-up of these patients for better prognostic evaluation and association of the HINE score with pre and perinatal clinical conditions

L’adénosine est un neuromodulateur ubiquitaire impliqué dans différents processus physiologiques et neuroprotecteurs du système nerveux central. Elle agit via quatre sous-types de récepteurs couplés à protéine G (A1, A2a, A2b et A3). Le récepteur A2a (A2aR) est fortement exprimé dans des régions riches en dopamine, avec de fortes concentrations dans la zone du caudate-putamen du cerveau, où elle a un rôle important dans la transmission neuronale et dans le processus dégénératif d’origine extrapyramidale. Ainsi, le blocage du récepteur A2a s’est révélé être une cible prometteuse pour le traitement des maladies neurodégénératives tels la Maladie de Parkinson (MP) et la Maladie d’Alzheimer (MA). A ce jour, seulement trois composés sont en phase clinique dans le cadre du traitement de la MP. Toutefois, bien que très affins, ils ne possèdent pas des propriétés ADME ou une sélectivité optimales.Au début de ce projet, la sous-structure Tic-hydantoïne a été identifiée comme présentant une bonne affinité pour A2aR. Après étude des fonctions manquantes de cette molécule et en respectant les éléments pharmacophoriques nécessaires pour une bonne activité, nous avons imaginé et évalué dans la structure co-cristallisé du A2aR et du ligand antagoniste de référence ZM241385 différentes modulations autour de l’hétérocycle. Ceci a permis de proposer la famille des Tic-guanidines, qui présente une fonction donneur de liaison hydrogène avec le résidu Asn253 du site et qui a été synthétisé après optimisation d’un chemin synthétique original. De plus, 1700 molécules ont été conçues de novo et évaluées in silico. Parmi les familles potentiellement intéressantes, deux d’entre elles, les quinolizidinones et les amino-imidazopyridines ont été synthétisées et évaluées in vitro afin de déterminer leur affinité vis-à-vis le récepteur A2a ainsi que leur cytotoxicité vis-à-vis les cellules neuronales. / Adenosine is a ubiquitous neuromodulator able to regulate many physiological processes and plays an important neuroprotective role in the central nervous system. Its effects are transmitted by four distinct G protein receptor subtypes designated A1, A2a, A2b, and A3. A2a receptors (A2aR) show a restricted distribution, being characteristic of the dopamine enriched areas, the highest concentration being in the caudate-putamen in brain, where it has an important role in neuronal signaling with this region and potential involvement in neurologic disease of extrapyramidal origin.A2a antagonism was shown to be a promising pharmacological target for neurodegenerative diseases such as Parkinson’s disease (PD) and Alzheimer disease (AD). Currently, only three compounds are still in clinical phase for PD treatment. Even if they show good affinities for the receptor, there is still a need for improving their ADME properties by keeping their selectivity towards other adenosine receptors.At the beginning of this project, a Tic-hydantoin derivative was identified as a new ligand with a good affinity for the A2a receptor. Based on the recently published crystalline structure of the A2A receptor complexed with the selective and high-affinity antagonist ZM241385 and a pharmacophoric model, we identified the missing features needed for a good affinity in our molecule. We designed and evaluated in silico many pharmacomodulations around the heterocyclic ring and Tic-guanidin substructure was proposed to present favorable hydrogen bound with Asn253 of the A2a binding site. This structure was obtained after optimization of a new synthetic pathway. Moreover, 1700 molecules were originally designed and evaluated in silico. Among potential interesting families, two of them, quinolizidinones and amino-imidazopyridines were synthesized and evaluated in vitro toward their affinity for A2a receptor and their cytotoxicity towards neuronal cells.
