title: Postural changes versus balance control and falls in community-living older adults: a systematic review

description: Abstract Introduction: Since falls are considered to be a public health problem, it is important to identify whether postural changes over time contribute to the risk of falls in older adults. Objective: To investigate whether postural changes increase fall risk and/or postural imbalance in healthy, community-dwelling older adults. Methods: In April 2016, two reviewers independently searched the PubMed, Web of Science, SPORTDiscus, and CINAHL databases for studies in English published in the previous 10 years, using the following combined keywords: “posture” or (“kyphosis”,“lumbar lordosis”,“flexed posture”,“spinal curvature”,“spinal sagittal contour”) AND “elderly” AND “fall”. Study quality was assessed according to the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines for observational studies. Results: The search retrieved 1,734 articles. Only observational studies that assessed posture, balance, and/or falls in older adults were considered eligible for review. The final sample included 17 articles: reliability and reproducibility of the instruments were not reported in five studies, while two studies offered a questionable description of the instruments used. Fourteen articles analyzed postural changes at the trunk level and three articles assessed them at the ankles and feet. Most studies found a positive association between postural changes and an increased risk for loss of balance and falls. Conclusion: Thoracic hyperkyphosis, loss of lumbar lordosis, and decreased plantar arch seem to contribute to greater postural instability, and thus to a higher risk of falls in community-living older adults.

title: Strength training protocols in hemiparetic individuals post stroke: a systematic review

description: Abstract Introduction: Hemiparesis is one of the main sequels of stroke. Evidence suggests that muscle strength exercises are important in rehabilitation programs for hemiparetic patients, but wide variation in previously studied protocols makes the most suitable choice difficult in clinical practice. Objective: The aim of this study was to investigate strength training protocols for people with hemiparesis after stroke. Methods: A systematic review of literature was performed in the PubMed, PEDro (Physiotherapy Evidence Database), SciELO (Scientific Electronic Library Online), and LILACS (Latin American and Caribbean Literature in Health Science) databases. Only controlled clinical studies that contained strength training protocols for hemiparesis after stroke were selected. Results: In total, 562 articles were found. Of them, 12 were accepted for the systematic review. Although strength training protocols are effective in hemiparetic patients, we did not found a standard method for strength training. Conclusion: This systematic revision highlights the lack of a standard protocol for strength training, considering the following training parameters: volume, intensity, frequency, series, and repetitions. Isotonic exercises are most commonly used.

title: Specialization in natural resources and global value chains

description: Abstract The paper proposes to characterize specialization in natural resources in the context of changes in international trade. In 1995 and 2009, the mapping, carried out from the decomposition of exports and cluster analysis, pointed to the strengthening of the regional productive integration of the countries. Countries in North America, Europe and Asia are inserted into value chains, while the Latin American countries, as well as South Africa, Saudi Arabia, among others, are limitedly integrated into international production networks as suppliers of raw materials with low capacity to extract value from the production chains in which they are inserted. The challenge for countries with natural resources is that they still have traditional trade patterns, therefore it is necessary to break the technical constraints of the industry, developing the process industry in order to insert these countries into more advanced stages of the production chain.

title: Teacher education and ethnic/racial content in ANPEd’s journal Revista Brasileira de Educação from 1995 through 2015

description: ABSTRACT Our goal is to analyze the focus of studies on race, ethnicity and teacher formation published in Associação Nacional de Pós-Graduação e Pesquisa em Educação Revista Brasileira de Educação, from 1995 to 2015. By correlating bibliographic and documentary sources, the qualitative approach was the main path of research. The predominance of the race-related subject matters was evidenced in the analysis, followed by ethnics. Correlation between race, ethnicity and other social features that characterize exclusion processes also composed the sample. Another important aspect to be highlighted was that the creation of the Study Group 21 and the Working Group 21 of that association and approval of laws 10,639/2003 and 11,645/2008 seem to directly influence the expansion of publications about racial-ethnic issues in Revista Brasileira de Educação.

title: Long-term microwaving of denture base materials: effects on dimensional, color and translucency stability

description: Abstract While the combined effect of microwave irradiation with cleansing solutions on denture base materials has been investigated, the effects of only using microwave irradiation and, more importantly, in a long-term basis, was not studied yet. Objective The purpose of this study was to evaluate the effect of a long-term repeated microwaving on the dimensional, color and translucency stability of acrylic and polyamide denture base materials. Material and Methods Thirty two specimens (32 mm x 10 mm x 2.5 mm) from polyamide (Valplast) and PMMA (Vertex Rapid Simplified) denture base materials were made. Eight specimens from each material were immersed in distilled water (control) and 8 were subjected to microwave exposure at 450 W for 3 minutes for a period simulating 224 days of daily disinfection. Linear dimension, color change (ΔE*) and translucency parameter (TP) were measured at baseline and after certain intervals up to 224 cycles of immersion, using a digital calliper and a portable colorimeter. The results were analysed using two-way repeated measures ANOVA to estimate possible differences among predetermined cycles and material type. Regression analysis was also performed to estimate the trend of changes with time. Statistical evaluations performed at a significance level of 5%. Results Data analysis showed significant changes in length at baseline with an increasing number of cycles (p&lt;0.05) and a significant interaction of cycle-material (p&lt;0.001). The ΔΕ* parameter was significantly higher with a higher number of cycles (p&lt;0.001), but it did not vary between materials (p&gt;0.05). TP decreased similarly in both materials following microwave action but in a significantly higher level for Valplast (p&lt;0.001). Conclusions The results indicated that long-term repeated microwaving affects linear dimensional, color and translucency changes of both materials. Differences between PMMA and polyamide material were noted only in dimension and translucency changes.

title: Predictors of Outcomes after Correction of Acute Type A Aortic Dissection under Moderate Hypothermic Circulatory Arrest and Antegrade Cerebral Perfusion

description: Abstract Introduction: Hypothermic circulatory arrest is widely used for correction of acute type A aortic dissection pathology. We present our experience of 45 consecutive patients operated in our unit with bilateral antegrade cerebral perfusion and moderate hypothermic circulatory arrest. Methods: Between January 2011 and April 2015, 45 consecutive patients were admitted for acute type A aortic dissection and operated emergently under moderate hypothermic circulatory arrest and bilateral antegrade cerebral perfusion. Results: Mean age was 58±11.4 years old. Median circulatory arrest time was 41.5 (30-54) minutes while the 30-day mortality and postoperative permanent neurological deficits rates were 6.7% and 13.3%, respectively. Unadjusted analysis revealed that the factors associated with 30-day mortality were: preoperative hemodynamic instability (OR: 14.8, 95% CI: 2.41, 90.6, P=0.004); and postoperative requirement for open sternum management (OR: 5.0, 95% CI: 1.041, 24.02, P=0.044) while preoperative hemodynamic instability (OR: 8.8, 95% CI: 1.41, 54.9, P=0.02) and postoperative sepsis or multiple organ dysfunction (OR: 13.6, 95% CI: 2.1, 89.9, P=0.007) were correlated with neurological dysfunction. By multivariable logistic regression analysis, postoperative sepsis and multiple organ dysfunction independently predicted (OR: 15.9, 95% CI: 1.05, 96.4, P=0.045) the incidence of severe postoperative neurological complication. During median follow-up of 6 (2-12) months, the survival rate was 86.7%. Conclusion: Bilateral antegrade cerebral perfusion and direct carotid perfusion for cardiopulmonary bypass, in the surgical treatment for correction of acute aortic dissection type A, is a valuable technique with low 30-day mortality rate. However, postoperative severe neurological dysfunctions remain an issue that warrants further research.

title: HOW TO OBTAIN GOLD NANOPARTICLES FROM LEMON JUICE?

description: This article refers about a green method for the preparation of gold nanoparticles using juice from four types of lemon (Tahiti, Key lime, Sicilian and Rangpur). The approach is based on a classic synthesis of nanoparticles using sodium citrate as reducing agent, since all these lemon varieties have citric acid in their compositions. Several characterization techniques demonstrated the efficacy of the method for obtaining red colloidal solutions (nanoparticles in the order of 5-25 nm). The importance of this attempt to make environmentally friendly synthesis of gold nanoparticles is linked to the several applications of these nanomaterials, the most important being biomedicine, catalysis, electronics, biochemical sensing and imaging.

title: Translation, linguistic and cultural adaptation, reliability and validity of the Radboud Oral Motor Inventory for Parkinson's Disease – ROMP questionnaire

description: ABSTRACT Objective: To translate and linguistically and culturally adapt to Brazilian Portuguese, and verify the reliability and validity of the Radboud Oral Motor Inventory for Parkinson's Disease (ROMP). Methods: The ROMP was translated and retranslated, and the instrument reliability was verified by analyzing the internal consistency and the reproducibility of the intra-examiner retest. The final version was applied to 27 participants with Parkinson's disease. Results: Internal consistency was 0.99 for the total ROMP and 0.96 to 0.99 for the three domains. Intraclass correlation coefficients for reproducibility were 0.99 for the total ROMP and 0.93 to 0.99 for the subscales. The ROMP and its subscales correlated substantially with the Likert-type scale, as well as with the unified Parkinson's disease rating scale II and III items. Conclusion: The linguistic and cultural equivalence of the ROMP in Brazilian Portuguese is now available, with excellent reliability and validity.

title: URBAN ACTIVISM IN SÃO PAULO

description: This paper presents a summary of the diverse occupations of public spaces in São Paulo, especially those in which activists (or similar) have been fighting for the expansion of rights to the city and its public facilities. These occupations are carried out by networks of collectives comprising students, artists, architects, associations and many other agents. A focus has been adopted on the understanding of a certain genealogy of these phenomena – of which the days of June 2013 represent an indispensable reference – as well as on the identification of the main ethnographic challenges to the anthropological approach.

title: Building Infestation Index for Aedes aegypti and occurrence of dengue fever in the municipality of Foz do Iguaçu, Paraná, Brazil, from 2001 to 2016

description: Abstract INTRODUCTION: the Building Infestation Index (BII) uses the Rapid Assay of the Larval Index for Aedes aegypti (LIRAa) to express the relationship between positive and surveyed properties. We evaluated LIRAa and the relationship between the BII and climate variables for dengue cases in Foz do Iguaçu municipality, Paraná. METHODS: Spearman’s correlations for mean precipitation, mean temperature, BII, and dengue cases (time lag). RESULTS: positive correlations between BII and cases, and mean temperature and cases at two months. Weak correlation between precipitation and cases at three months. CONCLUSIONS: LIRAa and climate variables correlate with dengue cases.
