Profissionais de saúde mental enquanto agentes de estigmatização da doença mental

A doença mental continua imbuída de mitos, preconceitos e estereótipos, apesar da crescente aposta na investigação e na melhoria de tratamento nesta área da saúde. Como consequência, as pessoas com doença mental são discriminadas e estigmatizadas quer pelo público geral e pelos meios de comunicação, quer pelas próprias famílias e pelos profissionais de saúde mental que lhes prestam cuidados. Uma vez que os profissionais de saúde mental estabelecem uma ponte entre a doença e a saúde, espera-se que as suas atitudes e práticas contribuam para o recovery da pessoa com doença mental. No entanto, se os profissionais também apresentarem atitudes e crenças estigmatizantes face à doença mental, este processo reabilitativo pode ficar comprometido. Nesse sentido, e perante as lacunas de investigação nesta área, este trabalho tem como objectivo explorar e clarificar a presença ou ausência de atitudes estigmatizantes dos profissionais de saúde mental e, quando presentes, como se caracterizam. Para tal realizaramse 24 entrevistas de carácter qualitativo a profissionais de saúde mental que trabalham em três instituições na região do Porto, nomeadamente num serviço de psiquiatria de um hospital geral, num hospital especializado e em estruturas comunitárias. A análise do material discursivo recolhido junto de Assistentes Sociais, Enfermeiros, Médicos Psiquiatras, Psicólogos e Terapeutas Ocupacionais evidencia a presença de crenças e atitudes de carácter estigmatizante face à doença mental, independentemente da idade, formação ou local onde exercem funções, salvo escassos aspectos onde parece haver influência da idade e da profissão. Significa isto que é provável que as variações de atitudes dos profissionais sejam fundamentalmente consequência das suas características pessoais.

The immediate effects of atlanto-occipital joint manipulation and suboccipital muscle inhibition technique on active mouth opening and pressure pain sensitivity over latent myofascial trigger points in the masticatory muscles

DESIGN: A randomized controlled trial.OB JECTIVE: To investigate the immediate effects on pressure pain thresholds over latent trigger points (TrPs) in the masseter and temporalis muscles and active mouth opening following atlanto-occipital joint thrust manipulation or a soft tissue manual intervention targeted to the suboccipital muscles. BACKGROUND : Previous studies have described hypoalgesic effects of neck manipulative interventions over TrPs in the cervical musculature. There is a lack of studies analyzing these mechanisms over TrPs of muscles innervated by the trigeminal nerve. METHODS: One hundred twenty-two volunteers, 31 men and 91 women, between the ages of 18 and 30 years, with latent TrPs in the masseter muscle, were randomly divided into 3 groups: a manipulative group who received an atlanto-occipital joint thrust, a soft tissue group who received an inhibition technique over the suboccipital muscles, and a control group who did not receive an intervention. Pressure pain thresholds over latent TrPs in the masseter and temporalis muscles, and active mouth opening were assessed pretreatment and 2 minutes posttreatment by a blinded assessor. Mixed-model analyses of variance (ANOVA) were used to examine the effects of interventions on each outcome, with group as the between-subjects variable and time as the within-subjects variable. The primary analysis was the group-by-time interaction. RESULTS: The 2-by-3 mixed-model ANOVA revealed a significant group-by-time interaction for changes in pressure pain thresholds over masseter (P<.01) and temporalis (P =.003) muscle latent TrPs and also for active mouth opening (P<.001) in favor of the manipulative and soft tissue groups. Between-group effect sizes were small. CONCLUSIONS: The application of an atlanto-occipital thrust manipulation or soft tissue technique targeted to the suboccipital muscles led to an immediate increase in pressure pain thresholds over latent TrPs in the masseter and temporalis muscles and an increase in maximum active mouth opening. Nevertheless, the effects of both interventions were small and future studies are required to elucidate the clinical relevance of these changes. LEVEL OF EVIDENCE : Therapy, level 1b. J Orthop Sports Phys Ther 2010;40(5):310-317. doi:10.2519/jospt.2010.3257. KEYWORDSDS: cervical manipulation, muscle trigger points, neck, TMJ, upper cervical.

Intelligent management of end consumers loads including electric vehicles through a SCADA system

The large penetration of intermittent resources, such as solar and wind generation, involves the use of storage systems in order to improve power system operation. Electric Vehicles (EVs) with gridable capability (V2G) can operate as a means for storing energy. This paper proposes an algorithm to be included in a SCADA (Supervisory Control and Data Acquisition) system, which performs an intelligent management of three types of consumers: domestic, commercial and industrial, that includes the joint management of loads and the charge/discharge of EVs batteries. The proposed methodology has been implemented in a SCADA system developed by the authors of this paper – the SCADA House Intelligent Management (SHIM). Any event in the system, such as a Demand Response (DR) event, triggers the use of an optimization algorithm that performs the optimal energy resources scheduling (including loads and EVs), taking into account the priorities of each load defined by the installation users. A case study considering a specific consumer with several loads and EVs is presented in this paper.

A efectividade da intervenção da fisioterapia nas disfunções crânio- cervico-mandibulares

Introdução: As teorias etiológicas recíprocas que relacionam as disfunções da articulação temporo mandibular (ATM) com as disfunções da coluna cervical, os seus critérios de diagnóstico e formas de tratamento, não reúnem consenso, constituindo, actualmente, uma temática de debate e investigação. Objectivo: Descrever a avaliação e intervenção em fisioterapia, e os seus resultados numa utente com disfunção do complexo crânio-cervico-mandibular. Métodos: Foi realizado um estudo observacional descritivo, do tipo estudo de caso, reportando-se a uma enfermeira, de 28 anos, com quadro sintomatológico compatível com disfunção crânio-cervico-mandibular, com antecedentes de condilectomia e artroplastia da ATM, aos 14 anos. Inicialmente a utente apresentava dor irradiada na região cervical (7/10) e limitação dos movimentos articulares da coluna cervical. Referia, também, dor na região do ptérion direito (6/10), limitação dos movimentos da mandíbula, desvio lateral na abertura da boca e dificuldades funcionais na mastigação. A avaliação inicial e final (após tratamento), foi efectuada recorrendo-se à utilização do Goniometro CROM e da Therabite Range of Motion Scale, para medição das amplitudes articulares da cervical e ATM, respectivamente; Estetoscópio, para avaliação dos sons articulares da ATM; Escala Visual Analógica para graduação da dor. A intervenção decorreu ao longo de 10 sessões, bissemanais. No tratamento, foram aplicadas técnicas sobre os trigers points da musculatura cervical e músculos da mastigação; Mobilização passiva da cervical e ATM; Manipulação dos segmentos vertebrais cervicais e torácicos; Streching e técnicas de energia muscular; Técnicas funcionais para a ATM; Técnicas miofasciais para a coluna cervical e ATM; Exercícios de controlo motor da coluna cervical. Resultados: No final do tratamento, as amplitudes dos movimentos cervicais estavam completas e sem dor (0/10), mantendo, sensibilidade dolorosa à palpação das espinhosas de C5-C6 (1/10). Relativamente à ATM, verifica-se a abolição da dor (0/10) e a ausência do desvio lateral da mandíbula na abertura da boca, bem como, o aumento das amplitudes de movimento na abertura da boca (33 para 36 mm), e no desvio lateral esquerdo (2 para 2,8 mm). Conclusão: os resultados sugerem que a intervenção, com recurso a técnicas de terapia manual, no caso em estudo, parecem surtir efeitos positivos no quadro sintomatológico e funcional da utente.

Planeamento e balanceamento de uma linha de montagem universal para formação

Este trabalho teve o intuito de criar uma linha de montagem universal através da qual será dada formação aos atuais operadores e a novos que possam vir a pertencer ao departamento de montagem na empresa Grohe Portugal. Para tal era necessário saber realizar um estudo de métodos e um estudo de tempos sobre os vários processos existentes no departamento de montagem. Com esse intuito foi elaborada uma pesquisa sobre as referidas temáticas, onde ficou evidente a sua importância e a sua imprescindibilidade. Inicialmente houve também um acompanhamento das montagens dos produtos nas várias linhas, de forma a adquirir conhecimento sobre as características dos processos de montagem existentes no departamento. Os pontos mais importantes durante o estudo de métodos e tempos realizado foram a definição de toda a estrutura do processo, das ferramentas e materiais a utilizar, não esquecendo a relação entre o operador e as suas ferramentas e a medição de tempos de todas as tarefas necessárias para cada processo de montagem. A linha de montagem, cujo projeto se desenvolveu, é composta por três bancadas e consiste num conjunto de postos de trabalho onde são executadas as operações através de máquinas, do trabalho humano, ou da sua conjugação, dispostos numa determinada sequência, sendo alguns deles amovíveis. Para a realização e conclusão deste projeto foram superadas diversas etapas, sendo que as mais relevantes foram:  a análise dos processos de montagem;  estudo de tempos de todas as famílias de produtos a serem implementados na linha de formação; - Definição da estrutura da linha de montagem; - Definição das rampas e dos tubos de abastecimento da linha; - Desenho da linha de montagem em 3D no software SolidWorks. Paralelamente foram também desenvolvidos estudos de tempos sobre alguns produtos com o intuito de serem implementadas melhorias, ou apenas para o controlo de tempos necessários para a realização das operações Por último, foi também elaborada uma recolha de ferramentas existentes no departamento de montagem para serem elaborados manuais de instruções das ferramentas fabricadas internamente, com o objetivo de obter a certificação OSHAS 180001 e de criar documentos com a listagem de materiais necessários para cada produto.

A tighter analysis of the worst-case endto- end communication delay in massive multicores

"Many-core” systems based on the Network-on- Chip (NoC) architecture have brought into the fore-front various opportunities and challenges for the deployment of real-time systems. Such real-time systems need timing guarantees to be fulfilled. Therefore, calculating upper-bounds on the end-to-end communication delay between system components is of primary interest. In this work, we identify the limitations of an existing approach proposed by [1] and propose different techniques to overcome these limitations.

Study on the changes of soil chemical characteristics as result of prescribed fire

Every year, particularly during the summer period, the Portuguese forests are devastated by forest fire that destroys their ecosystems. So in order to prevent these forest fires, public and private authorities frequently use methods for the reduction of combustible mass as the prescribed fire and the mechanical vegetation pruning. All of these methods of prevention of forest fires alter the vegetation layer and/or soil [1-2]. This work aimed the study of the variation of some chemical characteristics of soil that suffered prescribed fire. The studied an area was located in the Serra of Cabreira (Figure 1) with 54.6 ha. Twenty sampling points were randomly selected and samples were collected with a shovel before, just after the prescribed fire, and 125 and 196 days after that event. The parameters that were studied were: pH, soil moisture, organic matter and iron, magnesium and potassium total concentration. All the analysis followed International Standard Methodologies. This work allowed to conclude that: a) after the prescribed fire; i) the pH remained practically equal to the the initial value; ii) occurred a slight increase of the average of the organic matter contents and iron total contents; b) at the end of the sampling period compared to the initial values; i) the pH didn´t change significantly; ii) the average of the contents of organic matter decreased; and iii) the average of the total contents of Fe, Mg and K increased.

New end-use application for GFRP recyclates as reinforcement for concrete-polymer materials’

Glass fibre-reinforced plastics (GFRP), nowadays commonly used in the construction, transportation and automobile sectors, have been considered inherently difficult to recycle due to both: cross-linked nature of thermoset resins, which cannot be remolded, and complex composition of the composite itself, which includes glass fibres, matrix and different types of inorganic fillers. Presently, most of the GFRP waste is landfilled leading to negative environmental impacts and supplementary added costs. With an increasing awareness of environmental matters and the subsequent desire to save resources, recycling would convert an expensive waste disposal into a profitable reusable material. There are several methods to recycle GFR thermostable materials: (a) incineration, with partial energy recovery due to the heat generated during organic part combustion; (b) thermal and/or chemical recycling, such as solvolysis, pyrolisis and similar thermal decomposition processes, with glass fibre recovering; and (c) mechanical recycling or size reduction, in which the material is subjected to a milling process in order to obtain a specific grain size that makes the material suitable as reinforcement in new formulations. This last method has important advantages over the previous ones: there is no atmospheric pollution by gas emission, a much simpler equipment is required as compared with ovens necessary for thermal recycling processes, and does not require the use of chemical solvents with subsequent environmental impacts. In this study the effect of incorporation of recycled GFRP waste materials, obtained by means of milling processes, on mechanical behavior of polyester polymer mortars was assessed. For this purpose, different contents of recycled GFRP waste materials, with distinct size gradings, were incorporated into polyester polymer mortars as sand aggregates and filler replacements. The effect of GFRP waste treatment with silane coupling agent was also assessed. Design of experiments and data treatment were accomplish by means of factorial design and analysis of variance ANOVA. The use of factorial experiment design, instead of the one-factor-at-a-time method is efficient at allowing the evaluation of the effects and possible interactions of the different material factors involved. Experimental results were promising toward the recyclability of GFRP waste materials as aggregates and filler replacements for polymer mortar, with significant gain of mechanical properties with regard to non-modified polymer mortars.

P53 and Cancer-Associated Sialylated Glycans Are Surrogate Markers of Cancerization of the Bladder Associated with Schistosoma haematobium Infection

BACKGROUND: Bladder cancer is a significant health problem in rural areas of Africa and the Middle East where Schistosoma haematobium is prevalent, supporting an association between malignant transformation and infection by this blood fluke. Nevertheless, the molecular mechanisms linking these events are poorly understood. Bladder cancers in infected populations are generally diagnosed at a late stage since there is a lack of non-invasive diagnostic tools, hence enforcing the need for early carcinogenesis markers. METHODOLOGY/PRINCIPAL FINDINGS: Forty-three formalin-fixed paraffin-embedded bladder biopsies of S. haematobium-infected patients, consisting of bladder tumours, tumour adjacent mucosa and pre-malignant/malignant urothelial lesions, were screened for bladder cancer biomarkers. These included the oncoprotein p53, the tumour proliferation rate (Ki-67>17%), cell-surface cancer-associated glycan sialyl-Tn (sTn) and sialyl-Lewisa/x (sLea/sLex), involved in immune escape and metastasis. Bladder tumours of non-S. haematobium etiology and normal urothelium were used as controls. S. haematobium-associated benign/pre-malignant lesions present alterations in p53 and sLex that were also found in bladder tumors. Similar results were observed in non-S. haematobium associated tumours, irrespectively of their histological nature, denoting some common molecular pathways. In addition, most benign/pre-malignant lesions also expressed sLea. However, proliferative phenotypes were more prevalent in lesions adjacent to bladder tumors while sLea was characteristic of sole benign/pre-malignant lesions, suggesting it may be a biomarker of early carcionogenesis associated with the parasite. A correlation was observed between the frequency of the biomarkers in the tumor and adjacent mucosa, with the exception of Ki-67. Most S. haematobium eggs embedded in the urothelium were also positive for sLea and sLex. Reinforcing the pathologic nature of the studied biomarkers, none was observed in the healthy urothelium. CONCLUSION/SIGNIFICANCE: This preliminary study suggests that p53 and sialylated glycans are surrogate biomarkers of bladder cancerization associated with S. haematobium, highlighting a missing link between infection and cancer development. Eggs of S. haematobium express sLea and sLex antigens in mimicry of human leukocytes glycosylation, which may play a role in the colonization and disease dissemination. These observations may help the early identification of infected patients at a higher risk of developing bladder cancer and guide the future development of non-invasive diagnostic tests.

Evaluation of ultrasound, ultrasonophoresis and homeopathic mesotherapy on Cellulite treatment

Introduction: Cellulite is a complex architectural disorder with multifactorial etiologies that is prevalent in 98% of the women (1). Nowadays several aesthetic treatments are being used: surgical, cosmetic, physical, mechanical, and thermal. (2) Most treatments lack a substantial proof of efficacy. Objective: The purpose of this study was to test and evaluate the efficacy of Ultrasound, Homeopathic Ultrasonophoresis, and Homeopathic Mesotherapy versus control in cellulite in a population of women from ESTSP. Methods: Female volunteers (n=23), Caucasian, aged between 18-31 years, with BMI 19-27 kg/m2 with clinical cellulite gradation on the Cellulite Grading Scale of 1 to 4 were included in a control controlled study. Subjects were assigned in four different groups: Group I (Control, n=6), Group II (Ultrasound, (n=5), Group III (Homeopathic Ultrasonophoresis, n=6), Group IV (Homeopathic Mesotherapy, n=6). Groups II to IV were treated 3 times per week, for a total of 10 sessions. Cellulite gradation was evaluated at the beginning and the end of the trial by means of clinical photography, using a Canon IXUS 65 (6 mega pixels). For homeopathic treatments Dr. Reckeweg® Rekin® 59, 13 and 42 – Dietmed were used. The rating of perceived pain during Homeopathic Mesotherapy was evaluated by a visual analogic scale (VAS). The equipment Sonopuls 692, Enraf-Nonius was used for Ultrasound and Ultrasonophoresis treatments. Results:The higher number of participants with improvement in cellulite graduation occurred in group II (80%), followed group III (50%) and by group IV (33%). The group in which more changes in cellulite gradation occurred was group II, 20% of the individuals improved their score in 2 points. Results were statistically different between Group I and Group II, p=0,015. During the treatments of homeopathic mesotherapy the pain diminished 1 value in VAS scale. Discussion and Conclusion: Although all the three interventions groups were effective in the improvement of cellulite, as expected from previous works described in the literature, (2) only the ultrasound group was statistically different from control. These preliminary results point to the need of a new study using a higher number of participants and the same methodology.
