O impacto do uso da tala nocturna na funcionalidade do indivíduo com síndrome do túnel carpiano

A síndrome do túnel carpiano (STC) é considerada a neuropatia compressiva mais comum na população. É causada pela compressão directa sobre o nervo mediano no interior do túnel carpiano, que origina parestesias, dor na mão e disfunção muscular. Como consequência destes sintomas, os indivíduos vêem comprometida a sua funcionalidade ao nível das ocupações e, por consequência, alterado o seu desempenho ocupacional. Este trabalho tem como objectivo principal verificar de que forma a utilização da tala nocturna influencia a funcionalidade do indivíduo com STC. Concomitantemente pretende-se definir em que medida alterações das forças de preensão palmar e de pinças se relaciona com o uso da tala. Por último, identificar quais as variáveis sócio - demográficas e as que caracterizam a patologia que estão relacionadas com o problema em estudo e aos valores obtidos com as escalas do Boston Carpal Tunnel Questionnaire (BQTC), nos indivíduos dos grupos controlo e experimental. A amostra é constituída por 22 indivíduos no grupo controlo e 24 no grupo experimental, com diagnóstico de STC ligeiro e moderado. Foram aplicados o BCTQ, o dinamómetro e o pinch meter de Jamar. Os resultados deste estudo mostram uma diminuição significativa da sintomatologia da STC, após a aplicação da tala, nos momentos de reavaliação e follow up, (p=0,000 e p=0,004), assim como um aumento significativo da funcionalidade nos dois momentos (p=0,000 e p=0,004). Deste estudo conclui-se que a utilização da tala nocturna beneficia os indivíduos com STC ligeiro e moderado.

The Greatest lover: a post-colonial rewriting of My Fair Lady

INTRODUCTION The popular Hong Kong comedy, The Greatest Lover, re-incarnates one of the most popular western musicals, My Fair Lady. OBJECTIVES 1. To find out in what major ways My Fair Lady was rewritten as the Hong Kong Cantonese movie, Gungzi Docing (The Greatest Lover). 2. To find out the socio-political, socio-linguistic, and gender ideology behind the rewriting. METHODOLOGY 1. To note the similarity of the themes for both works – a creator falling in love with his/her creation, and class prejudice and cross-class romance. 2. To note how the times of The Greatest Lover differ from that of My Fair Lady. 3. To note how the main characters in The Greatest Lover differ from My Fair Lady in terms of profession, gender, etc. 4. To note how the plot of The Greatest Lover differs from that of My Fair Lady. 5. To note how focus on language in The Greatest Lover compares with that in My Fair Lady. 6. To discuss the ideological implications of the differences noted above, e.g. women in Hong Kong today have much higher status than women in Victorian England; the conflict between local Hong Kong people and both legal and illegal immigrants from Mainland China is even more serious than that between the British upper middle class and the lower class during the Victorian period. 7. Andre Lefevere (1992) argues that translation and adaptation are rewriting informed and influenced by the rewriter’s ideology, among other things. 8. Both Aline Remael (1995) and Patrick Cattrysse (1992) think that film adaptation is a kind of translation. 9. Sirkkus Aaltonen (2000) argues that drama translation mirrors the ideologies of the target society. CONCLUSION 1. The Greatest Lover projects local cultural significance onto My Fair Lady by helping us to appreciate an important Western work of art through the Hong Kong Cantonese perspective. 2. Broader issues in translation and intercultural studies are also considered.

Post-surgical wound infections involving Enterobacteriaceae with reduced susceptibility to ß-lactams in two Portuguese hospitals

The post-surgical period is often critical for infection acquisition. The combination of patient injury and environmental exposure through breached skin add risk to pre-existing conditions such as drug or depressed immunity. Several factors such as the period of hospital staying after surgery, base disease, age, immune system condition, hygiene policies, careless prophylactic drug administration and physical conditions of the healthcare centre may contribute to the acquisition of a nosocomial infection. A purulent wound can become complicated whenever antimicrobial therapy becomes compromised. In this pilot study, we analysed Enterobacteriaceae strains, the most significant gram-negative rods that may occur in post-surgical skin and soft tissue infections (SSTI) presenting reduced β-lactam susceptibility and those presenting extended-spectrum β-lactamases (ESBL). There is little information in our country regarding the relationship between β-lactam susceptibility, ESBL and development of resistant strains of microorganisms in SSTI. Our main results indicate Escherichia coli and Klebsiella spp. are among the most frequent enterobacteria (46% and 30% respectively) with ESBL production in 72% of Enterobacteriaceae isolates from SSTI. Moreover, coinfection occurred extensively, mainly with Pseudomonas aeruginosa and Methicillin-resistant Staphylococcus aureus (18% and 13%, respectively). These results suggest future research to explore if and how these associations are involved in the development of antibiotic resistance.

O impacto do uso da tala nocturna na qualidade de vida do indivíduo com Síndrome do Túnel Carpiano

Síndrome do Túnel Carpiano (STC) é uma neuropatia compressiva do nervo mediano ao nível da articulação rádio-cubital inferior. Caracteriza-se fisiologicamente pelo aumento da pressão ao nível do canal carpiano o que desencadeia a diminuição da função do nervo a esse nível. Independentemente da fase de evolução da patologia, o indivíduo apresenta défices motores e sensoriais que interferem com o desempenho dos seus diversos papéis ocupacionais e, concomitantemente, com a sua Qualidade de Vida (QV). Como forma de reduzir esse impacto, existem várias abordagens possíveis, entre as quais se destaca o uso da tala nocturna de repouso. Este trabalho tem como objectivo principal definir quais os benefícios do uso da tala nocturna e o impacto manifesto na QV do indivíduo com STC. Simultaneamente pretende-se definir em que medida a relação benefício/melhoria da dor e normalização sensitiva se relaciona com o uso da tala. Por último, identificar quais as variáveis sociodemográficas que estão relacionadas ao problema em estudo e aos valores obtidos com as escalas SF-36 e PDI, nos indivíduos dos grupos controlo e experimental. Para a realização deste estudo, utilizou-se uma amostra de 46 indivíduos do sexo feminino aos quais aplicouse as escalas referidas anteriormente e os Monofilamentos de Semmes-Weinstein. Os resultados obtidos com o SF-36 revelaram uma maior percepção do estado de saúde no domínio Saúde Geral, no grupo ao qual se aplicou a tala, sugerindo que esta intervenção permite uma melhoria da QV. Simultaneamente, o PDI permitiu inferir que a aplicação da tala nocturna tem um impacto positivo no que concerne à percepção do nível da dor nas diversas actividades da vida diária e, consequentemente, na QV. No que se refere à sensibilidade, os resultados obtidos não permitem afirmar que existem melhoras a este nível. Relativamente às variáveis socio-demográficas, apenas os casos classificados como ligeiros apresentam uma melhor percepção do nível de Saúde Geral o que é sugestivo de que com o evoluir da patologia há perda de QV.

Anticipatory postural adjustments during sitting reach movement in post-stroke subjects

The study assessed the effect of velocity of arm movement on the generation of APAs in the contralateral and ipsilateral muscles of individuals with stroke in the sitting position. In the sitting position, 10 healthy and 8 post-stroke subjects reached for an object placed at the scapular plane and mid-sternum height at self-selected and fast velocities. Electromyography was recorded from the anterior deltoid (AD), upper (UT) and lower trapezius (LT), and latissimus dorsi (LD). Kinematic analysis was used to assess peak velocity and trunk displacement. Post-stroke subjects presented a delay of APAs on both sides of the body compared to healthy subjects. Differences were found between the timing of APAs on the ipsilateral and contralateral LD and LT in both movement speeds and in the ipsilateral UT during movement of the non-affected arm at a self-selected velocity. A delay in the contralateral LD in the reaching movement with the non-affected arm at fast velocity was also observed. Trunk displacement was greater in post-stroke subjects. In the sitting position, APAs were delayed in both fast and self-selected movements on both sides in post-stroke subjects, which also presented a higher trunk displacement.

Optimising protocol of acquisition and post-processing procedures in the assessment of coronary artery disease by computed tomography

Coronary artery disease (CAD) is currently one of the most prevalent diseases in the world population and calcium deposits in coronary arteries are one direct risk factor. These can be assessed by the calcium score (CS) application, available via a computed tomography (CT) scan, which gives an accurate indication of the development of the disease. However, the ionising radiation applied to patients is high. This study aimed to optimise the protocol acquisition in order to reduce the radiation dose and explain the flow of procedures to quantify CAD. The main differences in the clinical results, when automated or semiautomated post-processing is used, will be shown, and the epidemiology, imaging, risk factors and prognosis of the disease described. The software steps and the values that allow the risk of developingCADto be predicted will be presented. A64-row multidetector CT scan with dual source and two phantoms (pig hearts) were used to demonstrate the advantages and disadvantages of the Agatston method. The tube energy was balanced. Two measurements were obtained in each of the three experimental protocols (64, 128, 256 mAs). Considerable changes appeared between the values of CS relating to the protocol variation. The predefined standard protocol provided the lowest dose of radiation (0.43 mGy). This study found that the variation in the radiation dose between protocols, taking into consideration the dose control systems attached to the CT equipment and image quality, was not sufficient to justify changing the default protocol provided by the manufacturer.

Exemplo de vulcanismo tardio em Portugal- rocha ígnea post-Miocénico inferior (Figueira-Algarve)

A small outcrop of an igneous rock (basanite) was observed in 1971 at Figueira-Mexilhoeira Grande-Algarve, enclosed by Miocene limestone and showing clear evidente of low grade thermal effects along the contact with the igneous mass. This is in agreement with F. L. Pereira Sousa who was the first geologist to admit (1917) the existence of Miocene igneous rocks in Algarve although subsequently they were not possible to localize. This work reports studies on petrography and chemical composition of this basanite and describes the evidence of the thermal effects upon the surrounding calcareous rocks. This well localized small outcrop represents an igneous rock more modern than the basaltic complex of Lisbon, hitherto assigned to the Eocene in age and recently ascribed to the Upper Cretaceous and until now considered the most recent manifestation of volcanic activity in Portugal. However this does not exclude the possibility of existence of even more modem igneous rocks in Algarve region.

Modifications of MCM-22 zeolite through sequential post-synthesis treatments. Implications on the acidic and catalytic behaviour

Desilication and a combination of alkaline followed by acid treatment were applied to MCM-22 zeolite using two different base concentrations. The samples were characterised by powder X-ray diffraction, Al-27 and Si-29 MAS-NMR spectroscopy, SEM, TEM and low temperature N-2 adsorption. The acidity of the samples was study through pyridine adsorption followed by FTIR spectroscopy and by the analyses of the hydroxyl region. The catalytic behaviour, anticipated by the effect of post-synthesis treatments on the acidity and space available inside the two internal pore systems was evaluated by using the model reaction of m-xylene transformation. The generation of mesoporosity was achieved upon alkaline treatment with 0.05 M NaOH solution and practically no additional gain was obtained when the more concentrate solution, 0.1 M, was used. Instead, Al extraction takes place along with Si, as shown by Si-29 and Al-27 MAS-NMR data, followed by Al deposition as extraframework species. Samples submitted to alkaline plus acid treatments present distinct behaviour. When the lowest NaOH solution was used no relevant effect was observed on the textural characteristics. Additionally, when the acid treatment was performed on an already fragilized MCM-22 structure, due to previous desilication with 0.1 M NaOH solution, the extraction of Al from both internal pore systems promotes their interconnection, evolving from a 2-D to a 3-D porous structure. This transformation has a marked effect in the catalytic behaviour, allowing an increase of m-xylene conversion as a consequence of an easier and faster molecular traffic in the 3-D structure. On the other hand, the continuous deposition of extraframework Al species inside the pores leads to a shape selective effect that privileges the formation of the more valuable isomer p-xylene.

Somewhere near reality: artistic portrayal of violence in post WWII British realistic drama

ABSTRACT - I will explore and present the portrayal of violence in some British plays that were staged between 1951 and 1965, in order to discuss the role, impact and aim of its representation. Thus, I will consider John Whiting’s Saint’s Day (1951), Ann Jelicoe’s The Sport of my Mad Mother (1956), Arnold Wesker (Chicken Soup with Barley (1958), Harold Pinter’s Birthday Party (1958), David Rudkin’s Afore Night Come (1962) and Edward Bond’s Saved (1965). My aim is to discuss the way how theatre in the post WWII changed the traditional ways of representing violence. On one hand, violence and reality became more and more familiar and domestic, permitting a representation of multiple and non-agonic violence; and, on the other hand, the violence that was depicted often changed the way one perceived reality itself, being part of a socially engaged artistic attitude.

POST-PROCESSING TECHNIQUES SUITABILITY FOR MESOLEVEL FREE BOUNDARY FLOWS

Reliable flow simulation software is inevitable to determine an optimal injection strategy in Liquid Composite Molding processes. Several methodologies can be implemented into standard software in order to reduce CPU time. Post-processing techniques might be one of them. Post-processing a finite element solution is a well-known procedure, which consists in a recalculation of the originally obtained quantities such that the rate of convergence increases without the need for expensive remeshing techniques. Post-processing is especially effective in problems where better accuracy is required for derivatives of nodal variables in regions where Dirichlet essential boundary condition is imposed strongly. In previous works influence of smoothness of non-homogeneous Dirichlet condition, imposed on smooth front was examined. However, usually quite a non-smooth boundary is obtained at each time step of the infiltration process due to discretization. Then direct application of post-processing techniques does not improve final results as expected. The new contribution of this paper lies in improvement of the standard methodology. Improved results clearly show that the recalculated flow front is closer to the ”exact” one, is smoother that the previous one and it improves local disturbances of the “exact” solution.
