A supervised versus home-based program effects on liver transplanted familial amyloidotic polyneuropathy patients: walking, fatigue and quality of life

Purpose: To evaluate the effects of a six months exercise training program on walking capacity, fatigue and health related quality of life (HRQL). Relevance: Familial amyloidotic polyneuropathy disease (FAP) is an autossomic neurodegenerative disease, related with systemic deposition of amyloidal fibre mainly on peripheral nervous system and mainly produced in the liver. FAP often results in severe functional limitations. Liver transplantation is used as the only therapy so far, that stop the progression of some aspects of this disease. Transplantation requires aggressive medication which impairs muscle metabolism and associated to surgery process and previous possible functional impairments, could lead to serious deconditioning. Reports of fatigue are common feature in transplanted patients. The effect of supervised or home-based exercise training programs in FAP patients after a liver transplant (FAPTX) is currently unknown.

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.

Efeitos de um programa de exercício na aptidão física pós transplante hepático: o caso da polineuropatia amiloidótica familiar nas suas componentes composição corporal, capacidade funcional e função neuromuscular

Introdução – A Polineuropatia Amiloidotica Familiar (PAF) é uma amiloidose sistémica heredo-degenerativa e autossómica dominante, e cuja manifestação predominante é a polineuropatia mista sensitiva motora e autonómica. Aos sintomas motores e sensitivos associam-se também alterações cardíacas, renais, urinárias, genitais e digestivas que se traduzirão em incapacidade funcional progressiva. Esta doença endémica de Portugal apresenta o seu início em média depois dos 20 anos com progressão para a morte em cerca de 10 anos. O tratamento etiopatogénico desta doença, com reconhecida eficácia, passa ainda pelo transplante hepático que apesar de tudo é efectuado já numa fase sintomática da doença e ao qual se encontra associada medicação com efeitos negativos para o metabolismo muscular e consequentemente para a capacidade de produção de força. Tanto a progressão da PAF como o próprio transplante resultam em limitações funcionais que podem ser melhoradas através do exercício físico. Do nosso conhecimento não existem estudos sobre a aptidão física destes pacientes submetidos a transplante hepático nem sobre os efeitos de um programa de exercício físico. Objectivo: Verificar o efeito de um programa de exercício físico combinado na aptidão física de indivíduos portadores de PAF submetidos a transplante hepático há menos de 12 meses. Adicionalmente, analisar de que modo algumas componentes da aptidão física (composição corporal, força muscular e capacidade funcional) seriam ou não e em que medida, diferentes da população saudável. Material e métodos: Trinta e nove pacientes PAF transplantados (4.3±3.3 meses pós transplante foram avaliados quanto à sua composição corporal (DEXA), força de preensão (dinamometro de preensão E-Link), força isométrica do quadricipete (dinamometria isocinética-Biodex) e capacidade funcional (teste 6 minutos de marcha - 6MWT e capacidade para a marcha – 6MWT×peso). Os níveis de actividade física e de qualidade de vida percebida foram avaliados respectivamente através dos questionários Seven Days Physical Activity Recall (7-PAR) e Medical Outcome Study item shortform Health Survey (SF-36Ò). Os pacientes foram alocados em três grupos: grupo de controlo(GC) com 16 pacientes (13H e 3M; 33±9 anos, IMC 22.6±3.3 kg.m-2) sem programa de exercício; grupo de exercício supervisionado (GES) com 8 pacientes (5H e 3M; 34±±7 years; IMC 20.4±4.5 kg.m-2) submetidos a um programa de exercício físico combinado trissemanal com a duração de 24 semanas e um grupo de exercício físico domiciliário ou home-based (GHB) com 15 pacientes (4H e 11M; 35±5 anos; IMC 22.3±4.3 kg.m-2) que fizeram exercício físico em casa durante 24 semanas. Para comparar variáveis da aptidão física entre pacientes PAF transplantados e indivíduos aparentemente saudáveis, submetemos 48 indivíduos PAF transplantados há menos de 12 meses e 24 indivíduos saudáveis não activos, ao mesmo protocolo de avaliação (composição corporal, força muscular e capacidade funcional). Resultados: O programa de exercício influenciou positivamente a composição corporal (peso, IMC, massa magra total e regional, massa muscular esquelética total e T-score do fémur proximal), o risco de incapacidade física, a capacidade para a marcha e a força de preensão da mão direita, mas não influenciou a percepção de qualidade de vida dos pacientes. A distância percorrida aumentou de forma clinicamente significativa apenas no grupo GES. Os pacientes PAF transplantados apresentaram valores inferiores aos indivíduos saudáveis na composição corporal (peso, IMC, massa óssea, massa gorda, massa magra e massa muscular) força muscular e capacidade funcional. Conclusões: O programa de exercício físico melhorou a composição corporal, capacidade funcional e força muscular e aumentou o peso corporal e o IMC nos doentes PAF. Esta melhoria foi maior no grupo GES do que no grupo GHB em todas as variáveis analisadas.

An approach to absorptive capacity based on the Portuguese textile industry

The main purpose of this research is to identify the hidden knowledge and learning mechanisms in the organization in order to disclosure the tacit knowledge and transform it into explicit knowledge. Most firms usually tend to duplicate their efforts acquiring extra knowledge and new learning skills while forgetting to exploit the existing ones thus wasting one life time resources that could be applied to increase added value within the firm overall competitive advantage. This unique value in the shape of creation, acquisition, transformation and application of learning and knowledge is not disseminated throughout the individual, group and, ultimately, the company itself. This work is based on three variables that explain the behaviour of learning as the process of construction and acquisition of knowledge, namely internal social capital, technology and external social capital, which include the main attributes of learning and knowledge that help us to capture the essence of this symbiosis. Absorptive Capacity provides the right tool to explore this uncertainty within the firm it is possible to achieve the perfect match between learning skills and knowledge needed to support the overall strategy of the firm. This study has taken in to account a sample of the Portuguese textile industry and it is based on a multisectorial analysis that makes it possible a crossfunctional analysis to check on the validity of results in order to better understand and capture the dynamics of organizational behavior.

MDAI: Model based Design in Automobile Industry

It is proposed a new approach based on a methodology, assisted by a tool, to create new products in the automobile industry based on previous defined processes and experiences inspired on a set of best practices or principles: it is based on high-level models or specifications; it is component-based architecture centric; it is based on generative programming techniques. This approach follows in essence the MDA (Model Driven Architecture) philosophy with some specific characteristics. We propose a repository that keeps related information, such as models, applications, design information, generated artifacts and even information concerning the development process itself (e.g., generation steps, tests and integration milestones). Generically, this methodology receives the users' requirements to a new product (e.g., functional, non-functional, product specification) as its main inputs and produces a set of artifacts (e.g., design parts, process validation output) as its main output, that will be integrated in the engineer design tool (e.g. CAD system) facilitating the work.

Application of GIS-based multi-criteria analysis for site selection of aquifer recharge with reclaimed water

Reclaimed water from small wastewater treatment facilities in the rural areas of the Beira Interior region (Portugal) may constitute an alternative water source for aquifer recharge. A 21-month monitoring period in a constructed wetland treatment system has shown that 21,500 m(3) year(-1) of treated wastewater (reclaimed water) could be used for aquifer recharge. A GIS-based multi-criteria analysis was performed, combining ten thematic maps and economic, environmental and technical criteria, in order to produce a suitability map for the location of sites for reclaimed water infiltration. The areas chosen for aquifer recharge with infiltration basins are mainly composed of anthrosol with more than 1 m deep and fine sand texture, which allows an average infiltration velocity of up to 1 m d(-1). These characteristics will provide a final polishing treatment of the reclaimed water after infiltration (soil aquifer treatment (SAT)), suitable for the removal of the residual load (trace organics, nutrients, heavy metals and pathogens). The risk of groundwater contamination is low since the water table in the anthrosol areas ranges from 10 m to 50 m. Oil the other hand, these depths allow a guaranteed unsaturated area suitable for SAT. An area of 13,944 ha was selected for study, but only 1607 ha are suitable for reclaimed water infiltration. Approximately 1280 m(2) were considered enough to set up 4 infiltration basins to work in flooding and drying cycles.

Large area image sensing structures based on a-SiC : H: a dynamic characterization

In recent works large area hydrogenated amorphous silicon p-i-n structures with low conductivity doped layers were proposed as single element image sensors. The working principle of this type of sensor is based on the modulation, by the local illumination conditions, of the photocurrent generated by a light beam scanning the active area of the device. In order to evaluate the sensor capabilities is necessary to perform a response time characterization. This work focuses on the transient response of such sensor and on the influence of the carbon contents of the doped layers. In order to evaluate the response time a set of devices with different percentage of carbon incorporation in the doped layers is analyzed by measuring the scanner-induced photocurrent under different bias conditions.

Individual pension information: Recommendations for the case of Spain based on the experiences of other countries

The aim of this paper is to establish some basic guidelines to help draft the information letter sent to individual contributors should it be decided to use this model in the Spanish public pension system. With this end in mind and basing our work on the experiences of the most advanced countries in the field and the pioneering papers by Jackson (2005), Larsson et al. (2008) and Sunden (2009), we look into the concept of “individual pension information” and identify its most relevant characteristics. We then give a detailed description of two models, those in the United States and Sweden, and in particular look at how they are structured, what aspects could be improved and what their limitations are. Finally we make some recommendations of special interest for designing the model for Spain.

Evaluation of the improvements on pharmacy technicians' work practices after implementation of operational procedures

Several antineoplasic drugs have been demonstrated to be carcinogenic or to have mutagenic and teratogenic effects. The greatest protection is achieved with the implementation of administrative and engineering controls and safety procedures. Objective: to evaluate the improvements on pharmacy technicians' work practices, after the implementation of operational procedures related to individual protection, biologic safety cabinet disinfection and cytotoxic drug preparation. Method: case-study in a hospital pharmacy undergoing a certification process. Six pharmacy technicians were observed during their daily activities. Characterization of the work practices was made using a checklist based on ISOPP and PIC guidelines. The variables studied concerning cleaning/disinfection procedures, personal protective equipment and procedures for preparing cytotoxic drugs. The same work practices were evaluated after four months of operational procedures implementation. Concordance between work practices and guidelines was considered to be a quality indicator (guidelines concordance practices number/total number of practices x 100). Results: improvements were observed after operational procedures implementation. An improvement of 6,25% in personal protective equipment practice was achieved by changing second pair of gloves every thirty minutes. The major progress, 10%, was obtained in disinfection procedure, where 80% of tasks are now realized according to guidelines.By now, we hot an improvement of only 1% at drug preparation procedure by placing one cytotoxic drug at a time inside the biological safety cabinet. Then, 85% of practices are according to guidelines. Conclusion: before operational procedures implementation 80,3% of practices were according to the guidelines, while now is 84,4%. This indicates that is necessary to review the procedures frequently in the benefit to reduce the risks associated with handling cytotoxic drugs and maintenance of drug specifications.
