Estágio profissional de intervenção em fisioterapia neurológica com pacientes adultos após aciente vascular cerebral

Mestrado em Fisioterapia NeurológicaIntrodução: A Fisioterapia Neurológica é uma área de intervenção essencial na medida em que existem cada vez mais doentes com sequelas resultantes de lesões do sistema nervoso central a necessitar de cuidados de fisioterapia, nomeadamente doentes com Acidente Vascular Cerebral já que as taxas de incidência são altas e a mortalidade tem vindo a decrescer com os avanços da medicina. Por outro lado, os conhecimentos atuais da área da neurociência permitem que a intervenção do fisioterapeuta seja baseada na evidência. Objetivos: Aprofundar conhecimentos, capacidades e competências em Fisioterapia Neurológica em pacientes adultos; intervindo essencialmente, em pacientes com sequelas de Acidente Vascular Cerebral, desenvolvendo o modelo de raciocínio clínico e investigando a efetividade do conceito de Bobath na funcionalidade de pacientes pós Acidente Vascular Cerebral. Metodologia: O estágio articulou a vertente de investigação, a dimensão pedagógica e a prática clínica; decorreu no Hospital Curry Cabral (Centro Hospitalar Lisboa Central) com pacientes adultos a realizar fisioterapia, em regime de internamento ou ambulatório, devido a patologia neurológica e mais especificamente com pacientes com sequelas de AVC; teve a duração de 200h. Foram selecionadas três escalas de funcionalidade (o Indicador de Barthel Modificado, a Medida de Independência Funcional e a Motor Assessement Scale) para a avaliação dos casos clínicos acompanhados e a abordagem em fisioterapia foi baseada no Conceito de Bobath. Resultados: Este estágio favoreceu a aquisição e consolidação de conhecimentos na área da Fisioterapia Neurológica, nomeadamente sobre o Conceito de Bobath e a avaliação da funcionalidade. São apresentados três casos clínicos de pacientes com sequelas de AVC que permitiram treinar a aplicação das escalas de funcionalidade, desenvolver o raciocínio clínico, aplicar as estratégias selecionadas e refletir sobre a eficácia da intervenção. Discussão: Embora não exista evidência robusta da superioridade do Conceito de Bobath em relação a outras abordagens, a sua filosofia facilita a avaliação e a tomada de decisão numa perspetiva holística sem menosprezar a individualidade de cada paciente. Das três escalas de funcionalidade aplicadas a Motor Assessement Scale é a única a levar em consideração a qualidade do movimento, o que a torna mais sensível a pequenas evoluções facilitando a mensuração adequada dos objetivos da intervenção. Conclusão: A realização deste estágio foi um período de aprendizagem importante e uma experiência enriquecedora no aspeto clínico, científico e académico.ABSTRACT - Introduction: Neurological Physiotherapy is an essential intervention area as there are more and more patients with sequelae resulting from injuries to the central nervous system requiring physiotherapy care, namely patients with stroke as the incidence rates are high and mortality has been decreasing with medical advances. On the other hand, current knowledge in the field of neuroscience allows the intervention of the physiotherapist to be based on evidence Objectives: To deepen knowledge, skills, and competencies in Neurological Physiotherapy in adult patients; essentially intervening in patients with sequelae of stroke, developing the model of clinical reasoning and investigating the effectiveness of the Bobath Concept in the functionality of patients after stroke. Methodology: The internship articulated the research aspect, the pedagogical dimension, and the clinical practice; it took place at Hospital Curry Cabral (Centro Hospitalar Lisboa Central) with adult patients undergoing physical therapy, inpatient or outpatient, due to neurological pathology and more specifically with patients with stroke sequelae; lasted 200 hours. Three scales of functionality were selected (the Barthel modified indicator the Functional Independence Measure and the Motor Assessment Scale) for the evaluation of the clinical cases followed and the approach in physiotherapy was based on the Bobath Concept. Results: This internship allowed the acquisition and consolidation of knowledge in the area of Neurological Physiotherapy, namely on the Bobath Concept and the evaluation of functionality. Three clinical cases of patients with stroke sequelae are presented, which allowed to train the application of the selected functionality scales, develop clinical reasoning and reflect on the effectiveness of the intervention. Discussion: While there is no robust evidence of the superiority of the Bobath Concept over other approaches, its philosophy facilitates assessment and decision-making from a holistic perspective without underestimating the individuality of each patient. Of the three scales of functionality applied the Motor Assessment Scale, is the only one to consider the quality of the movement, which makes it more sensitive to small developments, facilitating the adequate measurement of the intervention goals. Conclusion: This internship was an important learning period and an enriching experience in the clinical, scientific, and academic aspects.N/

TRPV4 activates autonomic and behavioural warmth-defence responses in Wistar rats

Aim In this study, we aimed at investigating the involvement of the warmth-sensitive channel - TRPV4 (in vitro sensitive to temperatures in the range of approx. 24-34 degrees C) - on the thermoregulatory mechanisms in rats.MethodsWe treated rats with a chemical selective agonist (RN-1747) and two antagonists (RN-1734 and HC-067047) of the TRPV4 channel and measured core body temperature, metabolism, heat loss index and preferred ambient temperature.ResultsOur data revealed that chemical activation of TRPV4 channels by topical application of RN-1747 on the skin leads to hypothermia and this effect was blocked by the pre-treatment with the selective antagonist of this channel. Intracerebroventricular treatment with RN-1747 did not cause hypothermia, indicating that the observed response was indeed due to activation of TRPV4 channels in the periphery. Intravenous blockade of this channel with HC-067047 caused an increase in core body temperature at ambient temperature of 26 and 30 degrees C, but not at 22 and 32 degrees C. At 26 degrees C, HC-067047-induced hyperthermia was accompanied by increase in oxygen consumption (an index of thermogenesis), while chemical stimulation of TRPV4 increased tail heat loss, indicating that these two autonomic thermoeffectors in the rat are modulated through TRPV4 channels. Furthermore, rats chemically stimulated with TRPV4 agonist choose colder ambient temperatures and cold-seeking behaviour after thermal stimulation (28-31 degrees C) was inhibited by TRPV4 antagonist.ConclusionOur results suggest, for the first time, that TRPV4 channel is involved in the recruitment of behavioural and autonomic warmth-defence responses to regulate core body temperature.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

Advances in the diagnosis and classification of gastric and intestinal motility disorders

Disturbances of gastric, intestinal and colonic motor and sensory functions affect a large proportion of the population worldwide, impair quality of life and cause considerable health-care costs. Assessment of gastrointestinal motility in these patients can serve to establish diagnosis and to guide therapy. Major advances in diagnostic techniques during the past 5-10 years have led to this update about indications for and selection and performance of currently available tests. As symptoms have poor concordance with gastrointestinal motor dysfunction, clinical motility testing is indicated in patients in whom there is no evidence of causative mucosal or structural diseases such as inflammatory or malignant disease. Transit tests using radiopaque markers, scintigraphy, breath tests and wireless motility capsules are noninvasive. Other tests of gastrointestinal contractility or sensation usually require intubation, typically represent second-line investigations limited to patients with severe symptoms and are performed at only specialized centres. This Consensus Statement details recommended tests as well as useful clinical alternatives for investigation of gastric, small bowel and colonic motility. The article provides recommendations on how to classify gastrointestinal motor disorders on the basis of test results and describes how test results guide treatment decisions
