title: Black Drums, White Ears: Colonialism and the Homogenization of Social and Cultural Practices in Southern Mozambique (1890-1940)

description: ABSTRACT In this article, I analyse how practices referred to generically in the historical documentation as ‘batuque’ (drums) underwent a process of homogenization and scrutinization by diverse Portuguese colonial agents. On one hand, the colonial agents insisted on unifying everything they saw as dance and music under the generic category of ‘batuque.’ On the other hand, the need for a better understanding of the subordinate Africans ended up producing colonial responses that shifted between a dissection of the term in search of a more accurate apprehension of what was being observed and an incorporation of these practices into the colonial enterprise. This process was conceived by the colonial agents as a way of appropriating the dances, songs and music made by the natives of southern Mozambique into the ultramarine Portuguese nationalist discourse.

title: SPECT/CT with 99mTc-sestamibi for the evaluation of skeletal muscle perfusion after electrical muscle stimulation in athletes

description: Abstract Objective: The purpose of this study was to evaluate the effects of electrical muscle stimulation (EMS) on muscles, using 99mTc-sestamibi SPECT/CT. Materials and Methods: We prospectively enrolled 20 consecutive male professional water polo players. The mean age was 25 years (range, 18-36 years). All athletes underwent 99mTc-sestamibi SPECT/CT of the thigh (rectus femoris and vastus medialis muscle groups) before and after EMS. Images were quantified to identify increases in perfusion after EMS. Results: Before EMS, there were no significant differences between the right and left thigh (rectus femoris and vastus medialis muscles) in terms of perfusion (p = 0.4). However, the comparison between the pre- and post-EMS analyses of the same muscle groups showed significant differences in radiotracer uptake (p &lt; 0.001), with a mean increase in perfusion of 128% for the rectus femoris muscle group (95% CI: 0.86-1.61) and 118% for the vastus medialis muscle group (95% CI: 0.96-1.79). Conclusion: 99mTc-sestamibi SPECT/CT is an objective means of evaluating blood flow in muscles submitted to EMS, which appears to promote significant increases in such blood flow.

title: Nutrients and bioactive compounds of pulp, peel and seed from umbu fruit

description: ABSTRACT: The objective of this research was to evaluate the nutritional composition and bioactive compounds of whole umbu fruit, including pulp, seed and peel, and also of a commercial umbu pulp. Samples of the fractions and of commercial pulp were analyzed for determination of minerals and proximate composition, total phenolic and antioxidant activity. Pulps and peel were also analyzed for vitamin C and carotenoids contents. Commercial pulp presented better nutritional composition than fresh pulp (P&lt;0.05) and the peel presented higher phenolic content and antioxidant activity than seed. Peel also stood out by its vitamin C (79 mg.100 g-1) and total carotenoids (2,751 µg.100 g-1) contents, showing that, as the main barrier of the fruit for its protection, it is a fraction rich in bioactive compounds. The highest dietary fiber and iron contents were observed in umbu seed (P&lt;0.05). Therefore, umbu by-products may be ingredients proper for development of food richer in nutrients and bioactive compounds.

title: Teaching to Learn: Ways of experiencing the practicum, teacher education and development

description: ABSTRACT This paper draws on findings from three interrelated research projects to analyze ways of experiencing the practicum, teacher education and development from an interventionist collaborative perspective. The shared fundamentals are 1) learning and development are societal-historical activities inherent to the nature of human beings; 2) being and identifying are functions of our total life, not only of episodic engagement with some task; 3) knowledge and knowing are integral to human active engagement with the world. Results indicate how different forms of participation provide opportunities for colearning and for developing critical reflexivity, ethical attitude, (pre)professional confidence and autonomy.

title: Computerization of primary health care in Brazil: the network of actors

description: ABSTRACT Objective: To analyze the network of human and non-human actors involved in the computerization of primary health care in the Brazilian federal government. Method: A qualitative study that used as a theoretical reference the actor-network theory and as a methodological reference the cartography of controversies. Data analysis was carried out using Gephi software, and through the extraction of reports, informed by the actor-network theory. Results: We found a network of 288 connections among 33 actors, composed mainly of nonhuman influencers of computerization. These actors are distributed throughout 3 inter-related communities, and manage the network by defining obligations, penalties, conflicts and intentionalities, thus influencing the success of the intended computerization. Final considerations: The network of actors at the federal level generates situations that, in many cases, hamper the successful implementation of a nationwide computerization strategy.

title: Is There Safety in the Use of Clopidogrel Loading Dose in Patients Over 75 Years of Age with Acute Coronary Syndrome?

description: Abstract Background: There is limited evidence in the literature regarding the administration of clopidogrel to acute coronary syndrome (ACS) in patients over 75 years of age. Most studies excluded this age group, making the subject controversial due to the increased risk of bleeding in this population. Objective: This is a retrospective, unicentric, and observational study aimed at assessing whether the administration of clopidogrel loading dose increases bleeding rates in patients over 75 years of age. Methods: Patients were divided into two groups: group I: 75 mg of clopidogrel; group II: 300-to 600-mg loading dose of clopidogrel. A total of 174 patients (129 in group I and 45 in group II) were included between May 2010 and May 2015. Statistical analysis: The primary outcome was bleeding (major and/or minor). The secondary outcome was combined events (cardiogenic shock, reinfarction, death, stroke and bleeding). The comparison between groups was performed through Q-square and T-test. The multivariate analysis was performed by logistic regression, being considered significant p &lt; 0.05. Results: Comparisons between groups I and II showed differences in the prevalence of diabetes (46.5% vs. 24.4%, p = 0.01), arterial hypertension (90.7% vs. 75, p = 0.01), dyslipidemia (62% vs. 42.2%, p = 0.021), ST segment elevation (11.6% vs. 26.6%, p = 0.016) and coronary intervention percutaneous (16.5% vs. 62.2%, p &lt; 0.0001), respectively. In the multivariate analysis, significant differences were observed between groups I and II in relation to the occurrence of bleeding (8.5% vs. 20%, OR = 0.173, 95% CI: 0.049 - 0.614, p = 0.007). Conclusion: A loading dose of 300 mg or more of clopidogrel.

title: Heart Failure: An Overview of Morbidity and Mortality in Rio Grande do Sul

description: Abstract Background: Heart failure (HF) is the final pathway of most cardiac diseases. Although the prevalence of HF has increased, due to the ageing of the population, more comprehensive data have shown a reduction in the percentage of HF hospital admissions over the last years. Objective: Assess the morbidity and mortality of HF patients in Brazil, Rio Grande do Sul and Porto Alegre. Method: The study is a retrospective analysis of data from the Brazilian Unified Health System's (Sistema Único de Saúde [SUS]) Department of Informatics (DataSUS). We evaluated the incidence of HF hospital admissions, the average length of stay, hospital costs and sex ratio, during a ten-year period (2007 to 2016). Due to availability of the system, mortality rate and age range, the total duration of the study was nine years. Results: Within this period, the percentage of hospitalizations for HF decreased. On the other hand, the length of stay increased in all regions studied. Mortality rates were in decline in all regions. Hospital costs showed an increase of 110.8%. HF was more prevalent in patients between the seventh and eighth decades of life, with men being more affected than women, except in Rio Grande do Sul. Conclusion: We conclude that, in spite of the high costs of HF to healthcare providers, hospitalizations and mortality rates have shown a significant decline over the last years, which results from the advances in the treatment of this disease, through initiatives to improve patient education, engagement and planning in health care and self-care.

title: Association between col1a2 Polymorphism and the Occurrence of Pelvic Organ Prolapse in Brazilian Women

description: Abstract Objective To evaluate the rs42524 polymorphism of the procollagen type I alpha (α) 2 (COL1A2) gene as a factor related to the development of pelvic organ prolapse (POP) in Brazilian women. Methods The present study involved 112 women with POP stages III and IV (case group) and 180 women with POP stages zero and I (control group). Other clinical data were obtained by interviewing the patients about their medical history, and blood was also collected from the volunteers for the extraction of genomic DNA. The promoter region of the COL1A2 gene containing the rs42524 polymorphism was amplified, and the discrimination between the G and C variants was performed by digestion of the polymerase chain reaction (PCR) products with the MspA1I enzyme followed by agarose gel electrophoresis analysis. Results A total of 292 women were analyzed. In the case group, 71 had the G/G genotype, 33 had the G/C genotype, and 7 had the C/C genotype. In turn, the ratio in the control group was 117 G/G, 51 G/C, and 11 C/C. There were no significant differences between the groups. Conclusion Our data did not show an association between the COL1A2 polymorphism and the occurrence of POP.

title: Effect of Hospital Accreditation Process in Outcomes of Patients with Acute Coronary Syndrome

description: Abstract Background: Hospital accreditation has as goal the standardization of patient care, aiming quality improvement. On 2015, a cardiology reference hospital was evaluated and got level 3 from ONA in care given to Acute Coronary Syndrome (ACS) patients. Objetive: To compare length of stay (LOS) at Coronary Care Unit (CCU) and the total LOS at the hospital of ACS patients before and after ONA 3 accreditation. Other clinical outcomes were also analyzed. Methods: Systematic and prospective registry of admitted ACS patients at CCU, whose population was divided into pre-accreditation (period 1) and post-accreditation (period 2). Descriptive analysis was performed. For statistical analysis the Mann-Whitney test, chi-squared, Fisher’s exact test and Multiple Linear Regression were performed. P value was considered statistically significant when &lt; 0,05. Results: 372 patients were admitted with ACS, 186 in period 1, of which 47 (25,3%) with ST segment Elevation Myocardial Infarction (STEMI), and 186 in period 2, of which 70 (37,6%) with STEMI. The mean age was 65,9 years (± 12,2). About the CCU LOS, there was a reduction from 3 (IQR: 2-4) to 2,5 days (IQR: 2-4; p value = 0,088). Regarding the hospital LOS, there was also a reduction from 8 (IQR: 5-12,25) to 6 days (IQR:4-11; p value = 0,004). Analyzing the type of ACS, there was a significant reduction only at the hospital LOS in non-STEMI patients: 8 to 6 days (p value = 0,001). Other hospitalization length of stay and clinical outcomes did not present a significant reduction in the comparison. Conclusion: After the ONA 3 accreditation, there was a reduction of hospital LOS. There were no significant differences in the other outcomes analyzed.

title: Transforming Urban Education in São Paulo: Insights into a Critical-Collaborative School Project

description: ABSTRACT The world is experiencing a particularly tense moment which asks for a project that goes beyond the limiting situations posed by immediate reality. This condition considers the critical immersion of individuals in their known realities and broad emersion in multiple contexts of understanding, which may broaden their horizons of perception. Vygotsky and recent followers offer us a basis for rethinking our reality in a collaborative and critical search for forms of development beyond who we are. This article brings about projects developed with schools from very poor and wealthy communities of São Paulo, where participants act together to transform their life conditions.
