Comparison of body fat content and distribution of familial amyloidotic polyneuropathy patients versus healthy subjects

The deposition of amyloid fibers at the peripheral nervous system can induce motor neuropathy in Familial Amiloidotic Polyneuropethy (FAP) patients. This produces progressive reductions in functional capacity. The only treatment for FAP is a liver transplant, followed by aggressive medication that can affect patients' metabolism. To our knowledge, there are no data on body fat distribution or comparison between healthy and FAP subjects, which may be important for clinical assessment and management of this disease.

Intermittent claudication and physical exercise: effectiveness of a home-based program

Peripheral arterial disease (PAD) as a high incidence in general population and 12% to 20% of population with more than 60 years has already clinical symptoms, such as intermittent claudication (IC), pain, loss of strength and functional incapacity. There are already some studies who refer the possible positive effects of physical exercise in functional consequences of PAD.

Effects of a randomized trial of exercise on body composition of liver transplanted patients

Liver transplantation is used as a only therapy so far, that stop the progression of some aspects of familial amyloidotic polyneuropathy disease (FAP) an autossomic neurodegenerative disease. FAP often results in severe functional limitations. Transplantation requires aggressive medication which impairs bone and muscle metabolism. Malnutrition plus weight loss is already one feature of FAP patients. All this may produce negative consequences on body composition. The effect of exercise training in FAP patients after a liver transplant (FAPTX) is currently unknown. The purpose of this study is to evaluate the effects of a six months exercise training program on body composition in FAPTX patients.

Relationship of balance to function independence in stroke survivors

Cerebral vascular disease is the primary cause of permanent disability in Portugal. Impaired stability is considered an important feature after stroke as it is related with higher risk of falls and functional dependence. Physiotherapy intervention usually starts early after stroke in order to direct motor recovery and help patients to improve their ability to perform activities of daily living (ADL). Purpose: to investigate the relationship of balance to functionality in acute stroke patients. Methods: 16 subjects (8 women and 8 men), mean age 63,62 ± 2,16y, with unilateral ischemic stroke in the middle cerebral artery territory, who were admitted to physiotherapy department of Fernando Fonseca Hospital in Portugal, within the first month after stroke were recruited to participate in this study. All subjects have no cognitive impairment according to Mini Mental State, no history of lower extremity orthopedic problems and no other disease that could interfere with treatments. All patients gave their inform consent to participate in this study. Subjects were assessed with the Modified Barthel Index (MBI) and the Berg Balance Scale (BBS).

Intermittent claudication and physical exercise: effectiveness of a home-based program

Peripheral arterial disease (PAD) as a high incidence in general population and 12% to 20% of population with more than 60 years has already clinical symptoms, such as intermittent claudication (IC), pain, loss of strength and functional incapacity. There are already some studies that refer the possible positive effects of physical exercise in functional consequences of PAD. The purpose of this study was to verify the results of a home-based (HB) weekly supervised physical exercise program in patients with IC in consequence of PAD in lower limbs, and observe the medium number of diary steps walked by the subjects of our study.

Effects of lower limb strengthening on balance and function in persons who suffered a stroke

Introduction - Cerebrovascular diseases, and among them, cerebral vascular accidents, are one of the main causes of morbidity and disability at European Union countries. Clinical framework resulting from these diseases include important limitations in functional ability of the these patients Postural control dysfunctions are one of the most common and devastating consequences of a stroke interfering with function and autonomy and affecting different aspects of people’s life and contributing to decrease quality of life. Neurological physiotherapy plays a central role in the recovery of movement and posture, however it is necessary to study the efficacy of techniques that physiotherapists use to treat these problems. Objectives - The aim of this study was to investigate the effects of a physiotherapy intervention program, based on oriented tasks and strengthening of the affected lower limb, on balance and functionality of individuals who have suffered a stroke. In addition our study aimed to investigate the effect of strength training of the affected lower limb on muscle tone.

Non-uniform printed antenna array for wireless communications in sports arenas

Wireless communications had a great development in the last years and nowadays they are present everywhere, public and private, being increasingly used for different applications. Their application in the business of sports events as a means to improve the experience of the fans at the games is becoming essential, such as sharing messages and multimedia material on social networks. In the stadiums, given the high density of people, the wireless networks require very large data capacity. Hence radio coverage employing many small sized sectors is unavoidable. In this paper, an antenna is designed to operate in the Wi-Fi 5GHz frequency band, with a directive radiation pattern suitable to this kind of applications. Furthermore, despite the large bandwidth and low losses, this antenna has been developed using low cost, off-the-shelf materials without sacrificing quality or performance, essential to mass production. © 2015 EurAAP.

Alterações da força de preensão em portadores de polineuropatia amiloidótica familiar

Introdução: A polineuropatia amiloidótica familiar (PAF) é uma doença autossómica dominante neurodegenerativa relacionada com a deposição sistémica de fibras de amiloide essencialmente a nível do sistema nervoso periférico. Clinicamente, caracteriza-se por uma neuropatia sensitivo-motora iniciando-se quase sempre nos membros inferiores e comprometendo subsequentemente as mãos. Até agora, o único tratamento conhecido com efeitos positivos no atrasar da progressão da doença é o transplante hepático com medicação com efeitos negativos para o metabolismo muscular e consequentemente para a capacidade de produção de força. Do nosso conhecimento, não existem caracterizações quantitativas dos níveis de força nestes indivíduos nem comparações com a população saudável. Este conhecimento seria extremamente importante para verificar a evolução clínica e funcional desta doença e para a eventual prescrição adequada de um programa de reabilitação. Objectivo: O objectivo deste estudo foi descrever e comparar os níveis de força de preensão (peak force) entre doentes PAF com ou sem transplante de fígado (PAFTx e PAFNTx, respectivamente) com um grupo de indivíduos saudáveis (GC). Material e métodos: A amostra total foi constituída por 206 indivíduos, divididos em três grupos: 59 indivíduos PAFNTx (23 homens, 36 mulheres; idade 35 ± 8 anos); 85 indivíduos PAFTx (52 homens, 33 mulheres; idade 34 ± 8 anos) e 62 GC (30 homens, 32 mulheres; idade 33 ± 9 anos). A força de preensão foi avaliada com um dinamómetro de preensão portátil E-Link (Biometrics Ltd, UK). Tanto as posições de medição como as ordens fornecidas foram estandardizadas. O valor de força máxima considerado foi classificado de acordo com as normas do American College of Sports Medicine (ACSM) para a força de preensão. Resultados: Os três grupos são diferentes (p < 0,05) no peso, no IMC e na força de preensão em ambas as mãos, bem como na resistência da mão esquerda. Foram encontradas correlações negativas entre a força e a idade, para os grupos PAFNTx e PAFTx, mas não para o grupo GC. Conclusões: De acordo com os nossos resultados, os indivíduos portadores de PAF apresentaram valores mais baixos para a força de preensão em ambas as mãos do que os indivíduos aparentemente saudáveis e consequentemente uma pior classificação nas normas do ACSM. A maioria dos doentes apresenta valores de força de preensão abaixo da média ou mesmo precária. Estes resultados poderão mostrar as implicações negativas na funcionalidade destes indivíduos e indicam também a necessidade de um programa de reabilitação com especificidade ao nível da motricidade da mão.

Strength, muscle quality and functional capacity in liver transplanted familial amyloidotic polineuropathy patients

Liver transplantation is the unique treatment for several end-stage diseases. Familial Amiloidotic Polineuropathy (FAP) is a neurodegenerative disease related with systemic deposition of amyloidal fiber mainly on peripheral nervous system, clinically translated by an autonomous sensitive-motor neuropathy with severe functional limitations in some cases. The unique treatment for FAP disease is a liver transplant with a very aggressive medication to muscle metabolism and force production. To our knowledge there are no quantitative characterizations of body composition, strength or functional capacity in this population.

Actividade física na criança com asma brônquica

Devido à sua prevalência, a asma brônquica (AB) é uma das patologias respiratórias mais frequente na nossa população. É de igual modo a doença crónica mais comum nas crianças. Outrora, a prática de qualquer actividade física era desaconselhada a crianças com AB. Hoje sabe-se que a actividade física pode ser um dos meios terapêuticos para controlar esta doença. São objectivos deste artigo reforçar a importância do exercício na criança asmática e dos benefícios desse mesmo exercício, não minimizando a asma induzida pelo exercício; evidenciar as linhas orientadoras do exercício segundo o American College of Sports Medicine (modalidades/tipo, frequência, intensidade, duração e condições especiais) para esta população; contribuir para diminuir os medos relativos à actividade física em crianças asmáticas presentes nos pais das crianças com asma e nas próprias crianças.

The discussion is based on the analysis of the mathematical practice developed by a group of four 9th grade students and is inspired by the social theory of learning

Strength, muscle quality and functional capacity in liver transplanted familial amyloidotic polineuropathy patients

Liver transplantation is the unique treatment for several end stage diseases. Familial Amiloidotic Polineuropathy (FAP) is a neurodegenerative disease related with systemic deposition of amyloidal fibre mainly on peripheral nervous system, clinically translated by an autonomous sensitive-motor neuropathy with severe functional limitations in some cases. The unique treatment for FAP disease is a liver transplant with a very aggressive medication to muscle metabolism and force production. To our knowledge there are no quantitative characterizations of body composition, strength or functional capacity in this population. The purpose of this study was to compare levels of specific strength (isometric strength adjusted by lean mass or muscle quality) and functional capacity (meters in 6 minutes walk test) between FAP patients after a liver transplant (4.1±2 months after transplant surgery) (FAPT) and a healthy group (HG).

Predicted VO2 on 6 minutes walk test for FAP liver transplanted patients

Physical function is limited post-liver transplantation and exercise training can improve exercise capacity following transplantation but previously assessment of functional capacity is necessary. The 6 minute walk test (6MWT) is routinely used for studying patient’s exercise capacity and is less expensive and time consuming than a Cardiopulmonary Exercise Test (CPXT). There have been some studies looking at the relationship between 6MWT and peak VO2 in patients but few presented an adequate equation for predicted peak VO2 from 6MWT to transplanted patients and none for Familial Amyloidotic Polyneuropathy (FAP) liver transplanted patients (FAPTx). The aim of this study was to compare the validity of 6 equations as predictors of VO2 from the 6MWT and compare it with directly measured VO2 in patients FAPTx.
