ABSTRACT: Introduction – Brain metastases are a problem due to the oncologic disease, which significantly limit patient survival and their quality of life. The stereotactic radiosurgery discloses a non-invasive removal of brain metastases. Objectives – Verify if stereotactic radiosurgery is more cost-effective than alternative treatments for brain metastases in cancer patients. Methods – We conducted a systematic review of literature using EBSCO host and PubMed between 2005 and 2015. The search terms were ‘radiosurgery’, ‘brain’, ‘metastasis’, ‘economics’, and ‘cost-benefit analysis’. The survey revealed 57 potentially eligible articles for the review, which were subject to an evaluation in accordance with the defined selection criteria. Three articles were included in the review. Results and Discussion – The review showed stereotactic radiosurgery dominance in relation to the two alternatives studied (total radiation of the brain and traditional surgery for resection of metastases). This superiority is associated with lower costs and equal or better effects (effectiveness or utility) of stereotactic radiosurgery. The cost of stereotacticradiosurgery seems to be the key differentiator relative to alternative treatments, lower than them in the three studies. Conclusion – The associated costs and effects of using stereotactic radiosurgery suggest that this will be the best option for a more rational treatment of patients with brain metastases. However, the findings are limited because of the scarcity of evaluated studies in the review.

A obesidade e considerada pela OMS um problema de saude publica, existindo mundialmente cerca 1,9 mil milhoes de pessoas com excesso de peso e destas, 600 milhoes sao obesas(1). Esta patologia representa um risco elevado para doencas cardiovasculares, diabetes, hipertensao e cancro(2). Na sua genese esta um desequilibrio entre a energia ingerida e a energia despendida. Este desequilibrio pode resultar de fatores psicologicos, ambientais, geneticos e metabolicos, indutores de perturbacoes do comportamento alimentar, como o aumento de ingestao alimentar ou de um estilo de vida sedentario. A regulacao do balanco energetico resulta de uma variedade de estimulos aferentes que sao processados no sistema nervoso central e respostas eferentes, reguladoras do apetite e saciedade. Os sinais aferentes podem ser transmitidos ao cerebro atraves do nervo vago ou pela via sistemica e envolver hormonas libertadas pelo tecido adiposo (leptina, adiponectina, resistina e visfatina) e pelo trato gastrointestinal (ghrelina, PYY, PP, GPL-1 e CCK). A resposta aos estimulos provoca ativacao ou inibicao de neuronios orexigenos (NPY, AgRP) e/ou anorexigenos (POMC, CART) localizados no hipotalamo. Enquanto a ativacao dos neuronios que expressam NPY e AgRP aumenta o apetite, a ativacao dos neuronios que expressam POMC ou CART origina saciedade(3). Muitos sao os estudos que procuraram compreender os mecanismos do balanco energetico. Contudo os resultados sao ainda, em alguns casos, pouco esclarecedores ou mesmo contraditorios. Com este artigo, pretende-se fazer uma revisao sobre os mecanismos de regulacao hormonal envolvidos na patogenese da obesidade, dando especial relevo as hormonas produzidas no tecido adiposo, estomago e intestino. Considerada uma epidemia do seculo XXI pela sua elevada prevalencia e complicacoes associadas, tornam-se cruciais mais estudos nesta area a fim de encontrar novas abordagens terapeuticas.

ABSTRACT: Objectives – To assess the effect of an exercise program targeting core muscles and lower limb muscles, in increasing balance in elderly living in the community. METHOD – Eleven subjects (10F; 1M), mean age 80±6.9 years old, independent and living in the community. The outcome measures included the Modified Clinical Test of Sensory Interaction on Balance (MCTSIB) performed on Balance Master® to measure balance; the Berg Balance Scale for fall risk; Falls Efficacy Scale for fear of falling; Sit-to-Stand 30 seconds for lower limb strength; Supine Bridge and Abdominal Stage Test for strength and endurance of core muscles and the 8-foot Up and Go Test for mobility. Results – There were statistical differences in Sit-to-Stand test, Supine Bridge test and MCTSIB Foam-Eyes Closed after the exercise program. Conclusion – An exercise program focused on training core and lower limb muscles did not show significant effects on balance in a sample of older adults living in the community, however it has increased lower limb strength and core muscles endurance.

ABSTRACT: Objectives – To evaluate and compare the efficacy of three different types of proprioceptive training in reducing the incidence of ankle sprains in male youth soccer players. Method – Muscle strength in tibiotarsal joint and proprioceptivity were evaluated and compared between three groups, with supervised proprioceptive training (GE), another unsupervised (GC1) and another with technical gesture training (GC2) over a nine week period, two to three times per week. Results – Both GE and GC1 showed significant increases (p<0.01) of proprioceptivity compared with GC2. Conclusion – The results suggest that after a short period of proprioceptive training, athletes improve their proprioceptivity but not necessarily tibiotarsal joint muscle strength. According to the study, supervision does not have an impact over training efficacy.

ABSTRACT: Some studies have shown the relationship between an increased and more structured involvement of patients in clinical decision making, the improvement of literacy in health and the obtainment of health gains. However, the existence of misconceptions on the part of doctors and other health professionals may contribute to their low compliance regarding shared clinical decision and discussion of treatment options, particularly with users with low levels of literacy. With this critical essay, we intend to clarify these misconceptions, by doing an in depth reflection and analysis on communication’s key elements centered on the patient – health literacy and shared decision. Relevant issues about literacy in health and shared decision were presented, on which critical content was developed. This development is the most extensive part of the essay. We transmitted the point of view of several authors and a critical analysis, and we tried to illustrate these ideas with examples and research studies, thus validating the presented arguments and answering to questions raised during the analysis. Final considerations of this critical essay stress that promoting an increased user participation in clinical decision making improves the level of health literacy, through a patient-focused communication performed by qualified professionals taking into consideration social determinants, and health gains are obtained.

ABSTRACT: Stereopsis is the perception of depth based on retinal disparity. Global stereopsis depends on the process of random dot stimuli and local stereopsis depends on contour perception. The aim of this study was to correlate three stereopsis tests: TNO ® , StereoTAB ® and Fly Stereo Acuity Test ® and to study the sensitivity and correlation between them, using TNO ® as the gold standard. Other variables as near convergence point, vergences, symptoms and optical correction were correlated with the three tests. Forty-nine students from Escola Superior de Tecnologia da Saude de Lisboa (ESTeSL), aged 18-26 years old were included. The stereopsis mean (standard-deviation-SD) values in each test were: TNO ® = 87.04’’ ±84.09’’; FlyTest ® = 38.18’’ ±34.59’’; StereoTAB ® = 124.89’’ ±137.38’’. About the coefficient of determination: TNO ® and StereoTAB ® with R 2 =0.6e TNO ® and FlyTest ® with R 2 =0.2. Pearson correlation coefficient shows a positive correlation between TNO ® and StereoTAB ® ( r =0.784 with α=0.01). Phi coefficient shows a strong and positive association between TNO ® and StereoTAB ® (Φ=0.848 with α=0.01). In the ROC Curve, the StereoTAB ® has an area under the curve bigger than the FlyTest ® with a sensivity of 92.3% for 94.4% of specificity, so it means that the test is sensitive with a good discriminative power.

Introduction – In vivo dosimetry is useful in measuring the dose administered to patients during treatment, assessing significant differences between the prescribed dose and the dose to the target volume and the organs at risk. Purpose – To compare the measured dose with the calculated dose in patients with breast tumours with and without physical wedge. Methods – Entrance dose measurements using p-type diodes were performed for tangential fields and relative field-in-field in all 38 patients. Results – Statistically significant differences in open tangential fields ( ρ =0.000) were verified. Discussion – Studies report significant systematic deviations between planned and measured dose. Conclusion – With this study we conclude that there is no influence in the doses due to the presence of the physical wedge.

Introduction – The informed consent (IC) for performing medical procedures is influenced by communication between the doctor and the patient, although the impact of some of the communication determinants between these actors is unknown. Purpose – To identify and analyse those determinants influencing the ethical duty to inform in order to obtain an informed consent. Methods – The search for original research papers written in Portugal, between January 2005 and March 2015, involved Scholar Google, PubMed, B-ON and the Portuguese Scientific Open Access Repository electronic databases, by using the keywords ‘ consentimento informado ’, ‘ medico ’ and ‘ doente ’ ou ‘ informed consent ’, ‘ doctor ’ and ‘ patient ’. Results – Five papers meeting the inclusion criteria were identified and communication determinants in the doctor-patient relationship were found to influence the free and clear IC. Conclusion – The knowledge of the importance of these communicational determinants influencing the IC can help the doctor-patient interaction and the development of measures to improve the healthcare performance.

ABSTRACT: The mammography technique is, currently, the most reliable imaging method for the diagnoses of breast cancer, and for this reason it is essential the production of mammograms with high quality and consistency. Considering that the goal of mammography is to maximize the visualization of breast tissue, the aim of this work is to explore the presentation of the pectoral major muscle in the mammographic image. We intended to assess the relationship between the technical procedures of the image acquisition and the presentation of the muscle, according to the current mammography quality criteria. The mammograms were collected from two reference hospitals in Porto, and thereafter, the image processing and statistics analysis was performed to assess qualitative and quantitative indicators of the image quality. In general, analyzing both clinical institution and based on these indicators, the hospital that uses a fixed angulation of the potter-bucky apart the patient's body habitus presented better results. This indicates that the existence of failures due to positioning errors is smaller when compared to the quality standard assessed. It was found, therefore, that the angulation of the potter-bucky device has a relevant and statistical significance on the quality of the mammographic images produced.

Introduction – Myocardial perfusion imaging (MPI) is a widely accepted study applied in the diagnosis and follow-up of coronary artery disease. Interpretation of myocardial perfusion images requires visual analysis of the reconstructed slices. The color scale selected can have a significant effect on the final appearance of the image and on the clinical interpretation of myocardial perfusion. Aim – Evaluate the influence of the color scale in the qualitative analysis of MPI and study which one should be preferably used for visual interpretation of myocardial perfusion. Methods – Thirty five MPI studies were visually interpreted by 16 nuclear medicine technologist students in the following color scales: Cool , Gray , Gray Invert , Thermal and Warm . Visual analysis of Cool ’s color scale relied on a semi-quantitative scoring system. The remaining color scales were evaluated by comparison with Cool . Results/Discussion – For Cool ’s color scale, inter-operator variability has shown statistically significant differences among all the participants ( p <0.05), which can be assigned to the subjectivity of the visual evaluation. The results obtained for Gray and Gray Invert colors scales were the closest for the myocardial perfusion observed with Cool , being alternative color scales suited for this purpose. Regarding Thermal and Warm color scales the results were divergent, showing that they are not the optimal choice for myocardial perfusion interpretation. Conclusion – The color scale selected can influence the qualitative assessment of MPI

Aim – Evaluate the influence of the color scale in the qualitative analysis of MPI and study which one should be preferably used for visual interpretation of myocardial perfusion. Methods – Thirty five MPI studies were visually interpreted by 16 nuclear medicine technologist students in the following color scales: Cool , Gray , Gray Invert , Thermal and Warm . Visual analysis of Cool ’s color scale relied on a semi-quantitative scoring system. The remaining color scales were evaluated by comparison with Cool . Results/Discussion – For Cool ’s color scale, inter-operator variability has shown statistically significant differences among all the participants ( p <0.05), which can be assigned to the subjectivity of the visual evaluation. The results obtained for Gray and Gray Invert colors scales were the closest for the myocardial perfusion observed with Cool , being alternative color scales suited for this purpose. Regarding Thermal and Warm color scales the results were divergent, showing that they are not the optimal choice for myocardial perfusion interpretation. Conclusion – The color scale selected can influence the qualitative assessment of MPI","PeriodicalId":30555,"journal":{"name":"Saude Tecnologia","volume":"1 1","pages":"19-27"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69246322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
