Effect of aquatic respiratory exercise-based program in patients with fibromyalgia

Objective: This study assessed the effects of an aquatic respiratory exercise-based program in patients with fibromyalgia (FMS). Methods: Forty women, aged between 20 and 60 years, were randomly assigned into two groups of 20 patients: the aquatic respiratory exercise-based program (ARG) and the control group (CTL). The ARG group performed the exercise program for 1 h, four times a week, for 4 weeks which included: (i) warming-Lip; (ii) respiratory exercises, consisting of five different breathing patterns, along With upper, lower limbs and trunk movements (45 min); and (iii) relaxation exercises. Both groups were included in supervised recreational activities of 1 h, once a week, for 4 weeks. Questionnaires were applied before and after intervention to assess quality of life and functional capacity (SF-36, Fibromyalgia Impact Questionnaire [FIQ]), anxiety (Hamilton Anxiety Scale [HAS]), and quality of sleep (Pittsburg Sleep Quality Index [PSQI]). Number of tender points and pain (Visual Analogue Scale [VAS]) were also evaluated. Results: At baseline there was no difference between the two groups, including number of tender points and questionnaire responses. After intervention, the ARG group, compared with the CTL group, showed improvement in SF-36 scores (physical functioning P = 0.001, bodily pain 1) = 0.001, vitality P = 0.009, social functioning P = 0.001, emotional role P = 0.001), in FIQ (total score P = 0.049, work missed P = 0.036, fatigue P = 0.013, morning tiredness P = 0.007) plus in VAS-pain (P = 0.029), VAS-dyspnea (P = 0.04), anxiety (HAS P = 0.005) and quality of sleep (PSQI P = 0.004). Conclusions: The short-term aquatic respiratory exercise-based program improved pain, quality of life, functional capacity, anxiety and quality of sleep in patients with FMS and may be a relevant addition to the treatment of these patients.

Melatonin reduces the severity of experimental amoebiasis

Background: Melatonin has immunomodulatory effects but very little is known about its influence in protozoan infections, such as Entamoeba histolytica, which causes amoebiasis, a disease with significant morbidity and mortality. In this study, we evaluated the effects of exogenous melatonin interference in experimental amoebiasis and on interactions between human blood cells and E. histolytica trophozoites. Methods: The effect of melatonin was investigated in models of experimental amoebiasis in hamsters and rats by evaluating the area of necrosis induced by E. histolytica. The activity of melatonin on the interactions between leukocytes and amoebae was determined by examining leukophagocytosis. For in vitro tests, polymorphonuclear and mononuclear human blood leucocytes were incubated with E. histolytica trophozoites. Results: The areas of amoebic necrosis were significantly reduced in animals treated with melatonin. Melatonin treatment increased leukophagocytosis but was associated with a greater number of dead amoebae. Conclusions: These results suggest that melatonin may play a beneficial role in the control of amoebic lesions, raising the possibility that this drug may be used as an adjuvant in anti-amoebic therapy.

Nível hemoglobínico em escolares da capital de São Paulo, Brasil

Com o objetivo de obter dados para avaliação do estado nutritivo dos escolares, o Serviço de Saúde Escolar da Secretaria da Educação do Estado de São Paulo, Brasil, realizou um inquérito laboratorial, usando como parâmetro a determinação da taxa hemoglobínica numa amostra de 20% dos 2.440 alunos do Grupo Escolar "Leonor Quadros", localizado em um bairro periférico da cidade de São Paulo. O método de exame utilizado constituiu na dosagem fotocolorimétrica da hemoglobina, empregando-se para isto um fotocolorímetro fabricado pelo Laboratório Ames do Brasil S/A. A taxa hemoglobínica média encontrada foi de 13,0 g%, sendo a média masculina de 13,09 g% e a feminina de 12,99g%. As taxas mínimas e máximas foram de 7,5 g% e 17,09 g%. Para melhor ordenação dos resultados, e de acordo com o nível hemoglobínico obtido, os escolares foram divididos em três grupos: o 1.° compreendendo escolares com nível hemoglobínico até 10,99 g%; o 2.º, entre 11,0 g% e 12,99g%, e o 3.°, acima de 13,0%. No primeiro grupo foram encontrados 2,3% dos alunos; no segundo, 36,2%, e no terceiro, 61,4%, verificando-se que 96% dos escolares apresentam nível hemoglobínico na faixa de 11,0 g% e mais. À vista dos resultados obtidos, considerou-se de razoável para bom o estado nutritivo dos escolares examinados.

A comparative benchmarking analysis of main Iberian container terminals: a DEA approach

Benchmarking is an important tool to organisations to improve their productivity, product quality, process efficiency or services. From Benchmarking the organisations could compare their performance with competitors and identify their strengths and weaknesses. This study intends to do a benchmarking analysis on the main Iberian Sea ports with a special focus on their container terminals efficiency. To attain this, the DEA (data envelopment analysis) is used since it is considered by several researchers as the most effective method to quantify a set of key performance indicators. In order to reach a more reliable diagnosis tool the DEA is used together with the data mining in comparing the sea ports operational data of container terminals during 2007.Taking into account that sea ports are global logistics networks the performance evaluation is essential to an effective decision making in order to improve their efficiency and, therefore, their competitiveness.

Surge damping analysis in pipe systems: modelling and experiments

The current study focuses on the analysis of pressure surge damping in single pipeline systems generated by a fast change of flow, conditions. A dimensionless form of pressurised transient flow equations was developed. presenting the main advantage of being independent of the system characteristics. In lack of flow velocity profiles. the unsteady friction in turbulent regimes is analysed based on two new empirical corrective-coefficients associated with local and convective acceleration terms. A new, surge damping approach is also presented taking into account the pressure peak time variation. The observed attenuation effect in the pressure wave for high deformable pipe materials can be described by a combination of the non-elastic behaviour of the pipe-wall with steady and unsteady friction effects. Several simulations and experimental tests have been carried out. in order to analyse the dynamic response of single pipelines with different characteristics, such as pipe materials. diameters. thickness. lengths and transient conditions.

Contact angle of a hemispherical bubble: An analytical approach

We have calculated the equilibrium shape of the axially symmetric Plateau border along which a spherical bubble contacts a flat wall, by analytically integrating Laplace's equation in the presence of gravity, in the limit of small Plateau border sizes. This method has the advantage that it provides closed-form expressions for the positions and orientations of the Plateau border surfaces. Results are in very good overall agreement with those obtained from a numerical solution procedure, and are consistent with experimental data. In particular we find that the effect of gravity on Plateau border shape is relatively small for typical bubble sizes, leading to a widening of the Plateau border for sessile bubbles and to a narrowing for pendant bubbles. The contact angle of the bubble is found to depend even more weakly on gravity. (C) 2009 Elsevier Inc. All rights reserved.

Six thinking hats for electricity markets simulation: adapting meeting tools to agent decision

In almost all industrialized countries, the energy sector has suffered a severe restructuring that originated a greater complexity in market players’ interactions. The complexity that these changes brought made way for the creation of decision support tools that facilitate the study and understanding of these markets. MASCEM – “Multiagent Simulator for Competitive Electricity Markets” arose in this context providing a framework for evaluating new rules, new behaviour, and new participants in deregulated electricity markets. MASCEM uses game theory, machine learning techniques, scenario analysis and optimisation techniques to model market agents and to provide them with decision-support. ALBidS is a multiagent system created to provide decision support to market negotiating players. Fully integrated with MASCEM it considers several different methodologies based on very distinct approaches. The Six Thinking Hats is a powerful technique used to look at decisions from different perspectives. This tool’s goal is to force the thinker to move outside his habitual thinking style. It was developed to be used mainly at meetings in order to “run better meetings, make faster decisions”. This dissertation presents a study about the applicability of the Six Thinking Hats technique in Decision Support Systems, particularly with the multiagent paradigm like the MASCEM simulator. As such this work’s proposal is of a new agent, a meta-learner based on STH technique that organizes several different ALBidS’ strategies and combines the distinct answers into a single one that, expectedly, out-performs any of them.

Falsificação de medicamentos no Brasil

OBJETIVO: Identificar os principais medicamentos falsificados apreendidos pela Polícia Federal brasileira e os estados em que houve a apreensão. MÉTODOS: Estudo retrospectivo descritivo dos laudos periciais elaborados por Peritos Criminais da Polícia Federal sobre medicamentos contrafeitos entre janeiro de 2007 e setembro de 2010. RESULTADOS: Os medicamentos com maior número de apreensões foram inibidores seletivos da fosfodiesterase 5, utilizados para tratar a disfunção erétil masculina (Cialis® e Viagra®, em média 66%), seguidos por esteróides anabolizantes (Durateston® e Hemogenin®, 8,9% e 5,7%, respectivamente). A maior parte dos medicamentos falsos foi apreendida nos estados do Paraná, São Paulo e Santa Catarina, com incremento superior a 200% no número de medicamentos inautênticos encaminhados à perícia no período. Houve aumento nas apreensões de medicamentos contrabandeados arrecadados em conjunto com os falsos; 67% das apreensões incluíram no mínimo um medicamento contrabandeado. CONCLUSÕES: A falsificação de medicamentos é um grave problema de saúde pública. A identificação das classes de medicamentos falsos no País e os principais estados brasileiros com essa problemática podem facilitar ações futuras de prevenção e repressão pelos órgãos brasileiros responsáveis.
