BACKGROUND@#Among former Olympic-level athletes, engagement in different sport disciplines has been associated with mortality risk in subsequent years. However, limited evidence is available on whether engagement in different sport disciplines at a young age is associated with locomotive syndrome (LS) risk later in life. This study examined the relationship between engagement in different sport disciplines during university years and LS risk in older age among former university athletes.@*METHODS@#Participants were 274 middle-aged and 294 older men alumni who graduated from a school of physical education in Japan. LS risk was defined as answering "yes" to any of the Loco-check questions. Data on university sports club membership were collected using questionnaires. University clubs were classified into three groups of cardiovascular intensity (low, moderate, high), following the classification system of sport disciplines by the American College of Cardiology. This classification considers the static and dynamic components of an activity, which correspond to the estimated percent of maximal voluntary contraction reached and maximal oxygen uptake achieved, respectively. University clubs were grouped based on the risk of bodily collision (no, yes) and extent of physical contact (low, moderate, high). Relationships between engagement in different sport disciplines and LS risk were analyzed using Cox proportional hazards models, and adjusted for age, height, weight, joint disease, habitual exercise, and smoking and drinking status.@*RESULTS@#Adjusted hazard ratios and 95% confidence intervals associated with the low, moderate, and high cardiovascular intensity sports were 1.00 (reference), 0.48 (0.22-1.06, P = 0.070), and 0.44 (0.20-0.97, P = 0.042) in older men, respectively; however, there was no significant association between these parameters among middle-aged men. Engagement in sports associated with physical contact and collision did not affect LS risk in either group.@*CONCLUSIONS@#Engagement in sports associated with high cardiovascular intensity during university years may reduce the risk of LS in later life. Encouraging young people to participate in such activities might help reduce LS prevalence among older populations.

Objective@#The aim of this study was to explore the ototoxicity of toluene in the early development of zebrafish embryos/larvae.@*Methods@#Zebrafish were utilized to explore the ototoxicity of toluene. Locomotion analysis, immunofluorescence, and qPCR were used to understand the phenotypes and molecular mechanisms of toluene ototoxicity.@*Results@#The results demonstrated that at 2 mmol/L, toluene induced zebrafish larvae death at 120 hours post fertilization (hpf) at a rate of 25.79% and inhibited the rate of hatching at 72 hpf. Furthermore, toluene exposure inhibited the distance travelled and average swimming velocity of zebrafish larvae while increasing the frequency of movements. As shown by fluorescence staining of hair cells, toluene inhibited the formation of lateral line neuromasts and middle line 1 (Ml @*Conclusion@#This study indicated that toluene may affect the development of both the inner ear and lateral line systems in zebrafish, while the lateral line system may be more sensitive to toluene than the inner ear.

The objective of this study was to examine the safety of multiple repeated percutaneous punctures of cisterna magna for collecting cerebrospinal fluid (CSF) and preliminarily determine the optimal time interval and volume at each collection. Sixty Wistar rats were randomly assigned to six groups: 10 d-0 μL, 10 d-100 μL (100 μL CSF collected at an interval of 10 days), 10 d-150 μL, 15 d-0 μL, 15 d-100 μL, and 15 d-150 μL. CSF was collected by percutaneous puncture of the cisterna magna at four time-points. Simultaneously, locomotor activity, cisterna magna pressure, and acetylcholine levels in the CSF were monitored. Compared with the 10 d-0 μL group, the escape latency by Morris water maze was significantly prolonged in the 10 d-100 μL and 10 d-150 μL groups (P<0.05). Compared with the 15 d-0 μL group, the indices of 15 d-100 μL and 15 d-150 μL groups had no significant differences. When compared with that at the first training, the exception of the 10 d-150 μL and 15 d-150 μL groups, significant differences in escape latency were found at the 6th attempt (P<0.05). Compared with baseline readings for each group, the cisterna magna pressure in the 10 d-150 μL group began to decrease significantly from the third measurement (P<0.05). The optimal time interval during four CSF collections (100 μL per collection) via cisterna magna percutaneous puncture was determined to be 15 days. The procedure did not significantly affect learning processes, performance, or other related indices.

ABSTRACT Objective: to analyze prevalence and the factors associated with locomotive syndrome in community-dwelling older adults. Method: a cross-sectional study, developed in a municipal center for the care of older adults in Teresina, Piauí, Brazil. The sample was for convenience and comprised 204 older adults aged 60 years or more, of both genders and with preserved cognitive capacity, according to parameters of the Mini Mental State Examination. Data collection occurred from March to November 2018, by applying a form for sociodemographic, clinical and falls occurrence characterization and the 25-item Geriatric Locomotive Function Scale. To measure the strength of the associations between the variables, odds ratios and 95% confidence intervals were adopted. The statistical significance level was set at 5% for the analyses. Results: the prevalence of locomotive syndrome found was 37.2%. The factors associated with the presence of locomotive syndrome were individual monthly income (p=0.005); existence of one of the following comorbidities: systemic arterial hypertension (p=0.039), osteoporosis (p=0.016), arthrosis (p<0.001) or obesity (p=0.014); and history of hospitalization in the last year (p=0.007). Conclusion: the prevalence of locomotive syndrome found in this study was low and presented higher levels in older adults, with an individual monthly income of two to three minimum wages; who reported having hypertension, osteoporosis, arthrosis or obesity; and with a history of hospitalization in the last year. The health condition investigated showed to be related to aging, with significant repercussions on functionality.

ABSTRACT OBJECTIVE: To evaluate locomotor activity in four field populations of Ae. aegypti with different insecticide resistance profiles from the state of São Paulo for two years. METHODS: This study comprised the susceptible Rockefeller strain and four populations from São Paulo, Brazil: two considered populations with "reduced susceptibility" to pyrethroids (Campinas and Marília), and two "resistant populations" (Santos and Ribeirão Preto). First, 2016 and 2017 eggs from these five populations were hatched in laboratory. Virgin females underwent experiments under laboratory conditions at 25°C, with 12:12h light/dark (LD) photoperiod; 24-hour individual activity was recorded using a locomotor activity monitor (LAM). RESULTS: In females from 2016 field populations, both resistant populations showed significant more locomotor activity than the two reduced susceptibility populations and the Rockefeller strain (p < 0.05). As for females from 2017 field populations, reduced susceptibility populations showed a significant increased locomotor activity than the Rockefeller strain, but no significant difference when compared to Santos resistant population (p > 0.05). CONCLUSIONS: Our results indicate that insecticide-resistant Ae. aegypti populations show increased locomotor activity, which may affect the transmission dynamics of their arboviruses.

RESUMO. Este estudo teve como objetivo investigar a percepção de educadoras frente às necessidades de duas bebês com deficiência física em contexto de inclusão na creche. Realizou-se um estudo de caso múltiplo, com seis educadoras que atendiam a turma de Mariana (24 meses), e quatro educadoras que atendiam a turma de Vitória (18 meses), as quais responderam uma entrevista semiestruturada. Ambas as bebês tinham deficiência física e frequentavam escolas de educação infantil da rede pública de Porto Alegre. Os dados foram analisados através de diversas leituras do material, produzindo um relato clínico. Em relação à Mariana, as educadoras destacaram a necessidade de estímulo e de suporte físico à bebê, bem como a importância do afeto na relação educadora-bebê, presente em um 'olhar a mais', mais sensível. Quanto à Vitória, as educadoras reforçaram a importância da integração entre as áreas da saúde e da educação, assim como de um olhar mais atento às diferentes necessidades da bebê com deficiência. A partir dos resultados, foi possível compreender nesse 'olhar a mais', destacado pelas educadoras como necessário para atender à demanda das bebês com deficiência física, uma exigência de maior disponibilidade corporal e psíquica.

RESUMEN. Este estudio tuvo como objetivo investigar la percepción de educadoras frente a las necesidades del bebé con discapacidad física en el contexto de inclusión en la guardería. Se realizó un estudio de caso múltiple, cuyas participantes fueron seis educadoras que atendían a la clase de Mariana, y cuatro educadoras que atendían a la clase de Vitória, las cuales respondieron una entrevista semiestructurada.

En cuanto a Vitória, 18 meses, las educadoras reforzaron la importancia de la integración entre las áreas de la salud y la educación, así como de una mirada más atenta a las diferentes necesidades de la bebé con discapacidad. A partir de los resultados, fue posible comprender en esa 'mirada a más', destacada por las educadoras como necesario para atender a la demanda de los bebés con discapacidad física, una exigencia de mayor disponibilidad corporal y psíquica.

ABSTRACT. This study aimed to investigate the perception of educators regarding the needs of two babies with physical disabilities in the context of inclusion in the day care center. A multiple-case study was carried out. The participants were six educators who oversaw Mariana's class, and four educators who oversaw Vitoria's class, and all 10 educators answered a semi-structured interview. Both babies were physically disabled and attended public schools in Porto Alegre/Brazil. The data were analyzed through several readings of the material, which resulted in a clinical report. In relation to Mariana (age 24 months) the educators emphasized the baby's need for stimuli and physical support, as well as the importance of affection in the educator-baby relationship, which was present as a more sensitive 'extra thought'. As for Vitória (age 18 months), educators reinforced the importance of integration between the health and education fields, as well as closer attention to the different needs of the disabled baby. Based on the results, it was possible to observe within that 'extra thought' - highlighted by the educators as necessary to fulfill the needs of babies with physical disabilities - a demand for greater physical and psychic availability.

O objetivo do presente estudo foi revisar os conceitos relativos ao funcionamento e alterações da supressão do reflexo vestíbulo-ocular (SRVO) e as principais formas de avaliação atualmente. Trata-se de uma pesquisa descritivo-exploratória, baseada em uma revisão da (El trabajo es una investigación descriptiva-exploratoria, basada en una revisión de la) literatura, realizada no (en el) Portal de Periódicos da Capes, no período de abril de 2020. Os (Los) operadores booleanos utilizados foram vestibulo-ocular reflex (OR), semicircular canal (OR), vestibular (AND) suppression. Como estratégia de pesquisa, na (en la) etapa de triagem (selección) foram utilizados os filtros: descritores no (en) título, publicações dos (de los) últimos dez anos, tipo de material, idioma e artigos revisados por pares. Dos 30 artigos triados (seleccionados), 20 apresentaram resumo de acordo com o tema e 13 estudos atenderam aos critérios de incluso (presentaron resúmenes relacionados al tema y 13 estudios cumplieron los criterios de inclusión). Scopus, Medline/PubMed e Science Citation Index Expanded foram as bases mais abrangentes (fueron las bases más abarcativas). A maioria dos (La mayoría de los) estudos, sobretudo os mais recentes, utilizaram os testes de impulso cefálico com o paradigma ´suppression head impulse test´ (SHIMP) comparando-o ao ´head impulse test´ (HIMP). A cadeira rotatória (La silla rotatoria) com eletronistagmografia foi o segundo teste mais utilizado. Apenas um estudo utilizou a Scleral Search Coil. A partir dessa revisão constata-se que a SRVO é influenciada pela idade, pode ser alterada por disfunções vestibulares periféricas unilaterais ou bilaterais, mas também por alterações neurológicas, como as cerebelares (las cerebelosas). Além da via visual, a SRVO pode ser desencadeada por fontes auditivas, somestésicas e até mesmo imagéticas (e incluso imaginativas, fantasiosas)

The present study aimed to review the concepts related to the functioning and changes in vestibular-ocular reflex suppression (VORS) and the most used assessments today. This is descriptive-exploratory research, based on a literature review, carried out on the Capes Journals Portal, in April 2020. The Boolean operators used were Vestibulo-ocular reflex (OR) Semicircular canal (OR) Vestibular (AND) Suppression. As a research strategy, in the screening stage, with the filters: descriptors in the title, last ten years, type of material, language, and peer-reviewed articles. Thirty articles were screened, 20 presented a summary according to the theme and 13 studies met the inclusion criteria. Scopus, Medline/PubMed, and Science Citation Index Expanded were the most comprehensive databases. Most studies, especially the most recent ones, used cephalic impulse tests with the SHIMP paradigm (suppression head impulse test) comparing it to the HIMP (head impulse test, HIMP). The rotary chair with electronystagmography was the second most used test. Only one study used the Scleral Search Coil. From this review, it appears that the SRVO is influenced by age; it can be altered by unilateral or bilateral peripheral vestibular disorders, but also by neurological changes, such as the cerebellar ones. In addition to the visual pathway, other sources can trigger SVOR, such as auditory, somesthetic and even imagery sources

A locomoção é uma função humana básica que permite ao indivíduo explorar seu ambiente e executar ações apropriadas. A locomoção também pode ser vista do ponto de vista energético, como uma forma de dissipar energia dentro de um sistema termodinâmico. Tradicionalmente, o controle da locomoção tem sido estudado sob a perspectiva de redes neuronais no sistema nervoso central. Abordagens mais recentes têm tentado fornecer uma visão diferenciada para o controle motor, como a abordagem dos Sistemas Dinâmicos ou Teoria dos Padrões Dinâmicos. Portanto, o objetivo do presente estudo foi revisar os princípios teóricos da aplicação da abordagem dos sistemas dinâmicos para o entendimento da locomoção humana e discutir as implicações práticas dessa abordagem para a área da reabilitação. A abordagem dos Sistemas Dinâmicos é uma teoria que assume a importância dos vários subsistemas do organismo humano, que seriam controlados pelas leis dinâmicas da física. De forma geral, seria um sistema de autoorganização que busca estratégias mais eficazes de acordo com os recursos disponíveis e as limitações impostas pelo ambiente. Através dessa linha de raciocínio, podemos interpretar como acontece o processo de locomoção humana, seus padrões de ocorrência e ainda aplicá-la para a marcha de populações especiais, como paralisia cerebral, acidente vascular encefálico, dor lombar, dentre outros. (AU)

Locomotion is a basic human function, which allows the individual to explore his environment and perform appropriate actions. The locomotion also can be seen from the energy point of view, as a means of dissipating energy in a thermodynamic system. Traditionally, the locomotion control has been studied from the standpoint of neural networks in the central nervous system. More recent approaches have been tried to provide a different perspective for motor control, such as the approach of Dynamical Systems or Dynamical Patterns Theory. Therefore, the objective of this study was to review the theoretical principles of the application of dynamical systems approach to understanding human locomotion and discuss the practical implications of this approach to the field of rehabilitation. The approach of Dynamical Systems is a theory that assess the importance of the various subsystems of the human body, which would be controlled by the dynamic laws of physics. In general, would be a system of self-organization looking for the most effective strategies in accordance with available resources and constraints imposed by the environment. Then, we can interpret the process of human locomotion, their patterns of occurrence and apply it to the gait of special populations, such as cerebral palsy, stroke, low back pain, among others.

O estudo da Anatomia Humana (AH) é parte integrante e de relevância inquestionável na graduação dos cursos da saúde. Com a constante redução na carga horária destinada à AH e diante dos debates sobre os novos métodos de ensino, o uso do código de quick response (código QR) se mostrou promissor. Nesse sentido, foi desenvolvido no Departamento de Anatomia da Universidade Estadual de Londrina (UEL) o processo de catalogação das estruturas anatômicas com o uso do código QR, sendo nosso objetivo relatar esta experiência. Neste processo, as estruturas dissecadas no Laboratório de Anatomia da UEL foram catalogadas com base em uma planilha contendo a correlação entre estruturas e números e, as informações de cada estrutura transcritas em um código QR através de um gerador eletrônico, sendo então impresso, plastificado e anexado à peça anatômica. As marcações foram realizadas por meio da sutura de etiquetas enumeradas. Dentro da discussão dos métodos alternativos de ensino há como exemplos a plastinação, a projeção em três dimensões e a prospecção. Em destaque neste relato, o uso do código QR mostrou-se como uma alternativa válida na agregação de conhecimento nos currículos acadêmicos. Por meio das atividades empreendidas no processo de catalogação, foi possível, além da aquisição de mais tempo dedicado ao conhecimento teórico-prático em AH, ampliar a independência no estudo e no desenvolvimento de pesquisas. Dessa forma, tem-se a oportunidade de se expandir as análises voltadas ao ensino da AH e aos novos métodos de aprendizado.

The study of human anatomy is a relevant part of the curriculum of health course graduation students. Given the constant reduction of hours destinated to the study of Anatomy and the debates regarding new teaching methods, the use of the Quick Response Code (QR code) has shown to be promising. Therefore, the Anatomy Department at the State University of Londrina (UEL) has developed a cataloging process concerning anatomical structures with the application of QR code, and this paper has the purpose of reporting on such experience. In the process, the structures dissected in UEL's Anatomy Laboratory were cataloged based on a spreadsheet which contained the correlation between these structures and numbers; the information regarding each structure was then transcribed into a QR code using a digital generator, with posterior printing, lamination and attachment to the body part. The labels were made by sewing the numbered tags onto the structures. Within the discussion regarding alternative teaching methods, examples can be given regarding lamination, three-dimension projection and prospection. The use of the QR code has proven to be a valid alternative in aggregating knowledge to academic curriculum. Through the activities performed in the process of cataloging, it was possible not only to dedicate more time to the theorical and practical learning of human anatomy, but also to increase the independence in studying and developing research. Furthermore, there is an opportunity to expand the analysis directed toward human anatomy teaching and toward new learning methods.

Método: para la obtención de información de la revisión de literatura sistemática, se buscaron artículos científicos en las bases de datos que a continuación se mencionan: SportDiscus con texto completo, psycINFO, Psychology and Behavioral Sciences Collection, Rehabilitation & Sports Medicine Source, google académico, Research Gate, PubMed. Resultados: las PDV, muestran una caminata cautelosa, probablemente para protegerse de las barreras arquitectónicas a las que podrían enfrentarse. Conclusiones: las PDV, presentan movimientos más cortos, lentos, lo que indica menores rangos de movimiento, afectando su funcionalidad, y generando un estrés muscular. Es muy importante la valoración de la caminata en las PDV, para que se desarrollen patrones adecuados y no presenten desbalances o acortamientos musculares. Logrando una mejora de su locomoción y con esta una mayor independencia.

Abstract Introduction: The gait in people with visual impairment (PWVI) has several variations that affect functionality and health, especially because it affects the skeletal muscle system. Purpose: to conduct a literature review to analyze the gait pattern and the implications it has on individuals with low vision and blindness. Method: a systematic review was held in the following databases: SportDiscus with full text, PsycINFO, Psychology, and Behavioral Sciences Collection, Rehabilitation & Sports Medicine Source, Google Scholar, Research Gate, PubMed. Results: The way of walking is slower in PWVI; they are cautious when walking to protect themselves, although the surrounding is clear. The disadvantage of this variable is that people do not walk in accordance with the optimal level of walking according to their age and height (recommended speed), so there would be no economy of movement; besides, its functionality is also affected. Conclusions: The research showed that the PWVI had atypical gait patterns. It was found, in some cases, greater ranges of movement in the involved joints, or on the diminished contrary movements, indicating small or forced movements, unnatural and, therefore, greater stress on muscle and bone. Evaluations in real situations on PWVI are very important to be able to provide them with tools that can help them in their walking and accessibility.

Resumo Introdução: A marcha para pessoas com deficiência visual (PDV) tem várias variações que afetam a funcionalidade e a saúde, especialmente porque impacta o sistema muscular esquelético. Objetivo: Realizar uma revisão da literatura para analisar o padrão de marcha e as implicações que ela tem nos indivíduos com baixa visão e cegueira. Método: a fim de obter informações da revisão sistemática da literatura, os artigos científicos foram pesquisados nas seguintes bases de dados: SportDiscus com texto completo, PsycINFO, Psychology, and Behavioral Sciences Collection, Rehabilitation & Sports Medicine Source, Google Scholar, Research Gate, PubMed. Resultados: os PDVs mostram uma caminhada cautelosa, provavelmente para se protegerem das barreiras arquitetônicas que podem enfrentar. Conclusões: A PDV apresenta movimentos mais curtos e lentos, o que indica menores intervalos de movimento, afetando sua funcionalidade e gerando estresse muscular. É muito importante a avaliação da marcha no PDV, para que padrões adequados sejam desenvolvidos e não apresentem desequilíbrios ou encurtamentos musculares, conseguindo uma melhora de sua locomoção e com isso uma maior independência.

Introdução: Pacientes após Acidente Vascular Encefálico (AVE) costumam ter alteração da marcha, apresentando velocidade lenta, baixa resistência a longas distâncias, e limitação da locomoção independente nas ruas. A recuperação dessa marcha comunitária é para esses indivíduos, um dos principais objetivos para a manutenção de uma vida ativa. Objetivo: Investigar a eficácia de uma intervenção fisioterapêutica com o método de tarefas orientadas e com o treino de marcha para trás sobre a locomoção de pacientes hemiparéticos após AVE. Métodos: Tratase de um estudo de análise de efeito terapêutico do tipo série de casos, no qual o sujeito é seu próprio controle, e são realizadas avaliações múltiplas para cada sujeito nas fases A1- B - A2. Na fase A1 são feitas duas avaliações antes do tratamento, gerando uma linha de base (baseline) que por ter duas medidas inclui a variação normal do sujeito, na fase B também são feitas duas avaliações, mas, durante e imediatamente após o tratamento, para obter as mudanças relacionadas ao mesmo e na fase A2 são feitas duas avaliações após duas semanas e um mês sem tratamento, para avaliar retenção do tratamento. Este estudo foi realizado com indivíduos com sequelas de AVE deambuladores comunitários (capazes de andar na rua, com ou sem auxílio de órteses). Os constructos utilizados para avaliar o efeito da terapia nos participantes foram: equilíbrio avançado, marcha comunitária com capacidade de modificar marcha as tarefas funcionais, equilíbrio e mobilidade, que foram investigados respectivamente com os instrumentos Fullerton Advanced Balance (FAB), Índice de Marcha Dinâmica (DGI) e Timed Up Go (TUG). Dois métodos estatísticos foram utilizados: 1) O método visual da banda formada pela média e por dois desvios padrão calculados com os resultados das avaliações feitas na baseline, formando uma banda cujos pontos que caírem fora da banda tem uma significância p < 0.05; e 2) O cálculo do tamanho do efeito da terapia com o método de Delta de Glass. Resultados: Participaram do estudo quatro voluntários com sequelas após AVE. Após aplicação do protocolo de intervenção com tarefas orientadas e marcha para trás, observou-se melhora do equilíbrio e mobilidade, assim como da locomoção e da capacidade de modificação da marcha às atividades funcionais, isso pode ser observado especialmente no TUG em que todos os participantes diminuiram o tempo, após o tratamento em aproximadamente 3 a 20 segundos, p < 0,05. Os tamanhos do efeito após terapia foram grandes a enormes > 0,80 e 1,30 para todos os participantes em dois dos três desfechos primários. Conclusão: A associação do treino por tarefas orientadas com o treino de marcha para trás dentro do processo de reeducação funcional de pacientes após AVE surte efeitos positivos sobre a locomoção.

Introduction: Patients after stroke usually have gait dysfunctions, presenting slow speed, low resistance over long walking distances, and limitation of independent walking outdoors. The recovery of community walking is for those individuals, one of the main goal necessary to keep an active life. Objective: To investigate the effectiveness of a physical therapy intervention with the task-oriented method associated with backward gait training on the locomotion of hemiparetic patients after stroke. Methods: This study is a case series, to analyze therapeutic effect, in which the subject is his own control, and multiple evaluations are performed for each subject in phases A1 - B - A2. In phase A1 two pre-treatment assessments are performed, generating a baseline that includes the normal variation of the subject. In phase B two assessments are also made, but during and immediately after treatment to obtain changes related to the treatment effect and, in phase A2, two assessments are made, after two weeks and one month without treatment, phase A2 is to assess retention of treatment. This study was conducted with community-walking strokes survivors (capable of walking on the street, with or without orthoses). The constructs used to assess the effect of therapy on participants were: advanced balance, community gait with ability to change functional tasks, speed and mobility, which were investigated with the Fullerton Advanced Balance (FAB) instruments, Dynamic Gait Index (DGI) and Timed Up Go (TUG). Two statistical methods were used: 1) The visual method of the band formed by the mean and by two standard deviations calculated from the results of the baseline evaluations, forming a band where the points that fall outside the band have a significance of p < 0.05 and 2) The size calculation of the effect of therapy with the Glass Delta method. Results: Four volunteers with stroke sequelae participated in the study. After applying the intervention protocol with task-oriented approach and backward gait training, it was observed an improvement in balance and mobility, as well as locomotion and gait modification ability to functional activities, that was observed especially in the TUG where all participants decreased the time after treatment in approximately 3 to 20 seconds, p <0.05. Post-therapy effect sizes were large to huge > 0.80 and 1.30 for all participants in two of the three primary outcomes. Conclusion: The association of task-oriented training with backward gait training within the functional rehabilitation process of patients after stroke has positive effects on locomotion. (AU)

Contradictory findings suggest that the behavioral and abuse-related effects of ethanol are mediated by its action at α1 subunit-containing GABAA (α1GABAA) receptors. In the present study, we investigated the effects of a sub-chronic post-ethanol administration treatment with zolpidem, an α1-preferring positive allosteric modulator at GABAA receptors, on the subsequent expression of ethanol-induced behavioral sensitization in mice. Animals received ethanol (1.8 g/kg, ip) or saline treatments every other day for 15 days (8 treatment sessions) and were subsequently treated with zolpidem (0.5 mg/kg, ip) or vehicle 4 times on alternate days. At the end of the treatment phase, animals were challenged with saline or ethanol on separate days for the evaluation of the expression of conditioned locomotion and behavioral sensitization. Eight-day treatment with ethanol did not lead to the development of ethanol-induced behavioral sensitization. Animals treated with ethanol and subsequently administered vehicle showed similar locomotion frequencies during the last ethanol challenge compared to the control group receiving ethanol for the first time. Animals treated with ethanol and subsequently administered zolpidem expressed behavioral sensitization to ethanol during the ethanol challenge. The present study adds to the literature by providing further evidence of a role of α1GABAA receptors on the behavioral effects of ethanol. Because of the current highly prevalent co-abuse of ethanol and benzodiazepine drugs in humans, the use of zolpidem and other α1GABAA receptor ligands during ethanol withdrawal should be monitored carefully.

Preclinical studies suggest that the GABA receptor is a potential target for treatment of substance use disorders. Baclofen (BLF), a prototypical GABA receptor agonist, is the only specific GABA receptor agonist available for application in clinical addiction treatment. The nucleus accumbens shell (AcbSh) is a key node in the circuit that controls reward-directed behavior. However, the relationship between GABA receptors in the AcbSh and memory reconsolidation was unclear. The aim of this study was to investigate the effect of intra-AcbSh injection of BLF on the reconsolidation of morphine reward memory. Male C57BL/6J mice were used to establish morphine conditioned place preference (CPP) model and carry out morphine reward memory retrieval and activation experiment. The effects of intra-AcbSh injection of BLF on morphine-induced CPP, reinstatement of CPP and locomotor activity were observed after environmental cues activating morphine reward memory. The results showed that intra-AcbSh injection of BLF (0.06 nmol/0.2 μL/side or 0.12 nmol/0.2 μL/side), rather than vehicle or BLF (0.01 nmol/0.2 μL/side), following morphine reward memory retrieval abolished morphine-induced CPP by disrupting its reconsolidation in mice. Moreover, this effect persisted for more than 14 days, which was not reversed by a morphine priming injection. Furthermore, intra-AcbSh injection of BLF without morphine reward memory retrieval had no effect on morphine-associated reward memory. Interestingly, administration of BLF into the AcbSh had no effect on the locomotor activity of mice during testing phase. Based on these results, we concluded that intra-AcbSh injection of BLF following morphine reward memory could erase morphine-induced CPP by disrupting its reconsolidation. Activating GABA receptor in AcbSh during drug memory reconsolidation may be a potential approach to prevent drug relapse.

O objetivo do presente estudo foi verificar se o índice de massa corporal e a atividade física influenciam no desenvolvimento motor e na aptidão física de crianças. Participaram 64 crianças com idade entre 9 e 10 anos de ambos os sexos, sendo avaliados: nível de atividade física, estado nutricional, aptidão física (força, flexibilidade e resistência) e desenvolvimento motor. A amostra foi dividida em quatro grupos, estratificados pelo nível de atividade física e estado nutricional. Os dados foram comparados por meio do teste de Kruskal-Wallis (p<0,05). Os resultados apontaram que 34,4% das crianças apresentaram massa corporal acima dos valores normativos e 50% eram sedentárias. A massa corporal elevada influenciou negativamente na resistência e na habilidade de controle de objetos, apesar que o nível de atividade física diminui o impacto da obesidade na força e na habilidade de locomoção. A flexibilidade não foi influenciada. Conclui-se que atividade física e estado nutricional podem influenciar na aptidão física e no desenvolvimento motor de crianças.

The purpose of this study was to assess the influence of body mass index and physical activity levels in the motor development and physical fitness of children. The study had the participation of 64 children aged between 9 and 10 years of both genders: physical activity level, nutritional status, physical fitness (strength, flexibility and endurance), and motor development. The participants were divided into four groups, stratified by level of physical activity and nutritional status. The data were compared using the Kruskal-Wallis test (p <0.05). Results: 34.4% of the children had body mass above normative values, ​​and 50% were sedentary. High body mass has negatively influenced the resistance and ability to control objects, although the level of physical activity decreases the impact of obesity on strength and ability to move. Flexibility was not influenced. Conclusion: physical activity and nutritional status may influence the physical fitness and motor development in children.

Objective: To evaluate whether an animal model of mania induced by lisdexamfetamine dimesylate (LDX) has an inflammatory profile and whether immune activation by lipopolysaccharides (LPS) has a cumulative effect on subsequent stimuli in this model. We also evaluated the action of lithium (Li) on inflammatory and neurotrophic factors. Methods: Adult male Wistar rats were subjected to an animal model of mania. After the open-field test, they were given LPS to induce systemic immune activation. Subsequently, the animals' blood was collected, and their serum levels of brain-derived neurotrophic factor and inflammatory markers (tumor necrosis factor [TNF]-α, interleukin [IL]-6, IL-1β, IL-10, and inducible nitric oxide synthase [iNOS]) were measured. Results: LDX induced hyperactivity in the animals, but no inflammatory marker levels increased except brain-derived neurotrophic factor (BDNF). Li had no effect on serum BDNF levels but prevented iNOS levels from increasing in animals subjected to immune activation. Conclusion: Although Li prevented an LPS-induced increase in serum iNOS levels, its potential anti-inflammatory effects in this animal model of mania were conflicting.

Determining kinematics of hindlimbs of theropod dinosaurs has been a challenge. Since cursorial birds are phylogenetically closest to theropod dinosaurs they are commonly used as a kinematic model of theropod dinosaur locomotion. Using a comparative biomechanical approach, we found that cursorial birds have a different morphology of legs than non avian theropodos and that appears to be that felines and ungulates share more morphological properties in the hindlimbs with theropod dinosaurs than cursorial birds. We calculated the ratio between the lower leg and the femur, and the relative length of the tibia and the metatarsus with respect to the length of the femur in cursorial birds, as well as felines, ungulates and non-avian theropods. We found that as the length of the femur increases, the length of the lower leg increases similarly in felines, ungulates and non-avian theropods. On the other hand, existing and extinct cursorial birds did not follow this pattern. This observation suggests that the hindlimb of cursorial birds are not well suited to serve as kinematic models for hindlimb of extinct theropod dinosaur locomotion.

Determinar la cinemática de los miembros pelvianos de los dinosaurios terópodos ha sido un desafío. Dado que las aves corredoras son filogenéticamente más cercanas a los dinosaurios terópodos, son comúnmente utilizadas como modelo cinemático de la locomoción del dinosaurio terópodo. Usando un enfoque biomecánico comparativo, encontramos que las aves corredoras tienen una morfología de pies diferente a la de los terópodos no aviares y parece ser que los felinos y los ungulados comparten más propiedades morfológicas en los pies con los dinosaurios terópodos que las aves corredoras. Calculamos la proporción entre la parte inferior de la pierna y el fémur, y la longitud relativa de la tibia y el metatarso con respecto a la longitud del fémur en aves corredoras, así como en los terópodos no aviares y ungulados. Encontramos que a medida que aumenta la longitud del fémur, la longitud de la parte inferior de la pierna aumenta de manera similar en los terópodos, los ungulados y los terópodos no aviares. Por otro lado, las aves corredoras existentes y extintas no siguieron este patrón. Esta observación sugiere que el miembro pelviano de las aves corredoras no es adecuada para servir como modelos cinemáticos de locomoción del miembro pelviano del dinosaurio terópodo extinto.

The biomechanical performance of limb bones is useful to reflect an animal's adaptation to external loads and behaviors. In this study, we used the finite element method to simulate the load acting on the intact femur of the Japanese quails (Coturnix coturnix japonica) in the context of terrestrial locomotion and take-off for flight, in order to explore the functional significance of the femoral form and limb postures. It is shown that the distribution of stress was similar in all cases, furthermore, the lower 2/3 of the dorsal and ventral region of the femur suffered higher stress, and the junction between the distal diaphysis and the medial condyle was the most vulnerable area. The stress reaches its highest value under the condition of about 90-100 degrees of loading angle; when this angle is larger than 110 degrees, the femur will be relatively safe. These findings suggested that quail femur is more suitable to terrestrial locomotion than take-off. This kind of work will contribute to revealing the locomotor behavior of fossil taxa.

El rendimiento biomecánico de los huesos de los miembros es útil para reflejar la adaptación de un animal a las cargas y comportamientos externos. En este estudio, utilizamos el método de elementos finitos para simular la carga que actúa sobre el fémur intacto de las codornices japonesas (Coturnix coturnix japonica) en el contexto de la locomoción terrestre y el despegue para el vuelo, con el objetivo de explorar la importancia funcional de la forma femoral y posición de los miembros. En el estudio, la distribución del estrés fue similar en todos los casos; además, los 2/3 inferiores de la región dorsal y ventral del fémur sufrieron un mayor estrés, y la unión entre la diáfisis distal y el cóndilo medial fue el área más vulnerable. La tensión alcanza su mayor valor bajo la condición de, aproximadamente, 90-100 grados de ángulo de carga; cuando este ángulo es mayor a 110 grados, el fémur esta relativamente seguro. Estos hallazgos sugieren que el fémur de codorniz es más adecuado para la locomoción terrestre que para el despegue. Este tipo de trabajo contribuirá a revelar el comportamiento locomotor de los taxones fósiles.

The mobile phone has been part of daily activities and offers various facilities for the elderly. Like other conveniences of modern life their use may have some effects that should be explored. Objective: To investigate the effect of cell phones on the functional mobility of adults (GA) and the elderly (GI). Method: 30 elderly, 70.96 ± 5.17 years old and 30 adults 23 ± 2.26 years old participated in this study. They were evaluated by MMSE, FES-I and TUG which was collected during the execution of 5 tasks (1 simple TUG, 2 TUG typing on the cell phone, 3 TUG answering questions on the cell phone, 4 TUG naming the days of the week in reverse, 5-TUG holding a glass with water). Results: There was a difference between the groups in FES-I (p = 0.001) and TUG in all analyzed tasks (p = 0.00001). The dual task (DT) of typing on the cell phone was the one that most affected the performance of the elderly in TUG (p = 0.00008) followed by DT 4 (conventional cognitive) p = 0.005 and DT 3 (p = 0.004). There was no effect of DT 5 (motor) (p = 0.03). For GA there was only effect of DT 2 (p = 0.027). Conclusion: Cellular use negatively impacted the performance of the elderly and can be considered a more realistic DT. The distraction generated by this task can increase the risk of falling and should be considered in preventive campaigns as well as rehabilitation programs.

O celular tem feito parte das atividades diárias e oferece várias facilidades para os idosos. Como outras conveniências da vida moderna seu uso pode apresentar alguns efeitos que devem ser explorados. Objetivo: Investigar o efeito do celular na mobilidade funcional de adultos (GA) e idosos (GI). Método: Participaram deste estudo 30 idosos, 70,96 ± 5,17 anos e 30 adultos 23±2,26 anos. Foram avaliados pelo MEEM, FES-I e TUG que foi coletado durante a execução de 5 tarefas (TUG 1 simples, TUG 2 dupla tarefa (DT) digitando ao celular, TUG 3 DT respondendo perguntas ao celular, TUG 4 DT nomeando os dias da semana ao contrário, TUG 5 DT segurando um copo com água). Resultados: Houve diferença entre os grupos na FES-I (p=0,001) e no TUG em todas as tarefas analisadas (p=0,00001). A DT de digitar ao celular foi a que mais afetou o desempenho dos idosos no TUG (p=0,00008) seguida pela DT 4 (cognitiva convencional) p= 0,005 e DT 3 (p=0,004). Não houve efeito da DT 5 (motora) (p=0,03). Para o GA só houve efeito da DT 2 (p=0,027). Conclusão: O uso do celular impactou de forma negativa a performance de idosos e pode ser considerado uma DT mais realista. A distração gerada por esta tarefa pode aumentar o risco de queda e deve ser considerada em campanhas preventivas assim como programas de reabilitação.

RESUMO O objetivo do estudo foi verificar se existem diferenças na força muscular dos membros inferiores (MMII) e na habilidade de locomoção de indivíduos pós-acidente vascular encefálico (AVE) crônico, classificados como deambuladores comunitários ou não comunitários. Foi realizado um estudo transversal em 60 indivíduos pós-AVE crônico, divididos em deambuladores comunitários (n=33) e não comunitários (n=27) pela velocidade de marcha. A força muscular de sete grupos musculares bilaterais de MMII foi avaliada por meio do teste do esfigmomanômetro modificado e habilidade de locomoção pelo ABILOCO. Estatísticas descritivas foram utilizadas para caracterizar a amostra, e o teste t de Student para amostras independentes, a fim de comparar os dois grupos de indivíduos pós-AVE. Observou-se que os deambuladores comunitários apresentaram maiores valores de força muscular para a maioria dos grupos musculares de MMII (−0,973≥t≥−3,189; p≤0,04), e na habilidade de locomoção (t=−2,841; p=0,006). Os indivíduos pós-AVE crônico deambuladores comunitários possuem maior força muscular de MMII e mais habilidade de locomoção em comparação aos deambuladores não comunitários. Sugere-se que a avaliação fisioterapêutica de indivíduos pós-AVE inclua, além da mensuração da força muscular de MMII e seu tratamento, a mensuração da percepção da habilidade de locomoção, para análises da evolução do paciente e da eficácia da conduta terapêutica.

RESUMEN El objetivo del estudio fue verificar si existen diferencias en la fuerza muscular de los miembros inferiores (MMII) y en la habilidad de locomoción de individuos post-accidente cerebrovascular encefálico (ACV) crónico, clasificados como deambuladores comunitarios o no comunitarios. Se realizó un estudio transversal en 60 individuos post-ACV crónico, divididos en deambuladores comunitarios (n = 33) y no comunitarios (n = 27) por la velocidad de marcha. La fuerza muscular de siete grupos musculares bilaterales de MMII fue evaluada por medio de la prueba del esfigmomanómetro modificado, y la habilidad de locomoción por el ABILOCO. Las estadísticas descriptivas se utilizaron para caracterizar la muestra, y la prueba t de Student para muestras independientes con el fin de comparar los dos grupos de sujetos post-ACV. Se observó que los deambuladores comunitarios presentaron mayores valores de fuerza muscular para la mayoría de los grupos musculares de MMII (−0,973≥t≥−3,189; p≤0,04), y en la habilidad de locomoción (t=−2,841; p=0,006). Los individuos post-ACV crónico deambuladores comunitarios poseen mayor fuerza muscular de MMII y más habilidad de locomoción en comparación a los deambuladores no comunitarios. Se sugiere que la evaluación fisioterapéutica de individuos post-ACV incluya, además de la medición de la fuerza muscular de MMII y su tratamiento, la medición de la percepción de la habilidad de locomoción, para análisis de la evolución del paciente y de la eficacia de la conducta terapéutica.

ABSTRACT The objective of this study was to verify if there are differences in the lower-limb muscle strength (LL) and in the locomotion ability among post-stroke patients classified as community or non-community ambulators. A cross-sectional study was conducted in 60 post-chronic stroke subjects, divided into community (n=33) and non-community (n=27) ambulators by gait speed. The muscle strength of seven bilateral muscle groups of LL was evaluated through the modified sphygmomanometer test and locomotion ability through ABILOCO. Descriptive statistics were used to characterize the sample, and Student's t-test was used for independent samples to compare the two groups of post-stroke individuals. We observed that community ambulators had higher values of muscle strength for most muscle groups of LL (−0.973≥t≥3.189; p≤0.04), and in the locomotion ability (t=−2.841; p=0.006). Community ambulators showed higher LL muscle strength and better locomotion ability compared with non-community ambulators. Physiotherapeutic evaluation of post-stroke individuals should include, besides the measurement of LL muscle strength and its treatment, the measurement of the perception of locomotion ability to analyze the evolution of the patient and the efficacy of the therapeutic behavior.
