title: Infective Endocarditis Surgery. Insights from 328 Patients Operated in a University Tertiary Hospital

description: Abstract Background Infectious endocarditis (IE) refers to infection of the endocardial surface of the heart and usually occurs in native or prosthetic valves. Objective This study aimed to raise IE data reflecting the surgical therapy in a University Hospital in the interior of the State of Sao Paulo–Brazil. Method Retrospective and observational approach of 328 patients with IE who underwent surgery between 1982 and 2020 Results The main data (n=121/37%), congestive heart failure (n=114/35%), valve disease (n=92/28%), diabetes mellitus (n=85/26%), chronic kidney disease (n=59/18%), and rheumatic fever (49/15%). Renal failure is one of the main and most relevant pre-surgical risk factors for a poor prognosis. Conclusion For a better clinical and surgical outcome, an early syndromic and etiological diagnosis of IE is necessary, especially in patients with multiple comorbidities.

title: Team-based learning in remote teaching of health promotion and education at Medical School

description: Abstract: Introduction: Team-Based Learning (TBL) is a method widely used in the teaching of health promotion as it instigates the exercise of skills such as leadership, teamwork and decision-making. With the emergence of the COVID-19 pandemic, there was a general need to adapt medical education to the remote environment. Thus, the objective of this article is to describe the experience of adapting a curricular component of Public Health to the online scenario, maintaining TBL as a teaching-learning methodology of health promotion, even during the pandemic. Experience Report: The method was applied through videoconferences and a platform with resources for the application of tests according to the TBL format. With the meetings, students developed essential skills about health promotion, such as salutogenesis, the illness metaphor during the process of getting sick, prevention and health education. Discussion: TBL develops students’ skills such as teamwork, leadership and dialogue. These competencies are prescribed in the National Curricular Guidelines for undergraduate medical training, and are essential in the practice of health promotion. Furthermore, the discipline promoted a salutogenic construction of the students’ capacities, developing skills based on their potential, just as in an operational group. Also, the application of TBL allowed the continued smooth teaching of health promotion despite the remote learning scenario, because this methodology encourages active learning and offers the possibility of applying the knowledge obtained in practical situations. The main limitations of the experience were difficulties encountered in accessing distance learning platforms, the limitations to non-verbal communication and the control over consultation materials during the execution of each stage. Conclusion: The adaptation of the TBL method to the remote scenario stimulated the practice of communicative and argumentative skills that are essential to the work with operative groups in the community and allowed students to apply the learned concepts in practical situations, despite the remote learning environment.

title: Ichthyofauna on the move: fish colonization and spread through the São Francisco Interbasin Water Transfer Project

description: Abstract Projects on river basin integration are keen social-economical drivers in dry regions like the Brazilian semiarid, however, there are concerning ecological impacts implied in those projects. In a long-term analysis, ichthyofauna colonization and spread through the East Axis of the São Francisco River Integration Project (SFIP) was monitored to assess possible impacts on the receiving Paraíba River basin. The fish were collected semiannually (2012 to 2021) from 19 sites in the São Francisco (SF) and Paraíba (PB) basins. A total of 69 fish species were recorded, with distinct fish assemblages between SF (n = 50), PB (n = 35), and the SFIP artificial reservoirs (n = 25). The SFIP reservoirs were colonized by species from the donor basin (SF). In a pioneer finding, Anchoviella vaillanti was recorded for the first time in the receiving basin and it is in the process of establishment. The two SF species that reached PB through the SFIP canals (A. vaillanti and Moenkhausia costae) may be using their year-round reproduction and wide diet to successful spread and colonize the new environment. Since we detected species with potential to reach the receiving basin and became invasives, the implementation of barriers to contain their spread are recommended.

title: Potential for drinking water savings through rainwater use: a case study in Brazil

description: Abstract This article assesses the potential for drinking water savings through a rainwater harvesting system for non-potable purposes in a flat. The appliances’ water flows were measured; users made daily notes of water consumption, time of use of each appliance, and the number of times this occurred; and daily readings of the water meter were made over fifteen days. Based on these data, the water end-uses and the average daily consumption were calculated. The measurements showed that the percentage of water for activities that do not require drinking water (toilet flushing, cleaning and washing machine) was 36.5% of the total consumption. Through the Netuno computer programme, the ideal capacities of rainwater tanks were determined for variable and average water consumption. It was found that a 10,000-litre tank provides drinking water savings of 34.8%, fully meeting the demand over 95% of the days. The study showed that, even with a considerable variation in consumption, the ideal capacity of the lower tank and the water savings achieved do not vary significantly when using variable or the average water consumption.

title: EXPLORING SPENT COFFEE GROUNDS ENERGY POTENTIAL IN THE BRAZILIAN SCENARIO

description: ABSTRACT Coffee stands out worldwide for being widely traded and consumed. However, this consumption generates a large amount of spent coffee grounds (SCGs) that are typically arbitrarily discarded. This biomass has a high heating value and molecular composition that allows for it to be a raw material for generating heat and energy. The search for renewable energy sources should consider the potential of SCGs. Thus, the objective of this study was to estimate the energy potential of SCGs in Brazil. The methodology consisted of searching for data to represent the generation of SCGs in the country and estimate its energy potential. It was found that the amount of SCGs available for power generation through direct combustion was approximately one thousand tons, and the power generation potential was 6.83 TWh/year in Brazil. This energy is sufficient to meet, for example, the total annual demand for public lighting in the country's Southeast. These results are the first steps towards evaluating the potential use of SCGs as an energy source and its environmental benefits. Additionally, this study explored limitations and barriers, providing valuable information for developing routes for using this energy residue and incentives for public policies.

title: Study of the rheological and microstructural properties of a geopolymer binder based on fly ash

description: Abstract Geopolymers are a potential alternative substitute for Portland cement binders in some applications. However, there are many unexplored research topics to be conducted on this subject. Thus, this study aimed to investigate the rheological and mechanical properties of geopolymer pastes based on Class F fly ash activated by a solution of NaOH and Na 2 SiO 3 , with activator/precursor ratios of 0.5, 0.6 and 0.7, by mass. Furthermore, microstructural and chemical analyses. Rheological properties were determined from flow tests with shear rates between 0 s -1 and 100 s -1 at 25°C. Mechanical analysis was performed from simple compressive strength tests on the hardened pastes. The results of simple compression indicated better strength values for lower activator/precursor ratios. In flow tests, the material behaved as a pseudoplastic fluid, and, with the increase of the activator/precursor ratio, there was a reduction of apparent viscosity values. Therefore, by evaluating the mechanical and rheological results, it was noticed that the paste that presented the best properties was the one with activator/precursor ratio 0.6.

title: Learning styles of health professions undergraduate students from a single institution

description: Abstract: Introduction: The concept of “learning styles” derives from theories postulating that students learn by following diverse pathways and that learning is more effective when the adopted teaching strategies more closely match specific student characteristics and learning preferences. Objectives: To determine, in first-year students attending different undergraduate courses in the health area at the same higher education institution, the frequency of different learning styles, categorized according to the four dimensions of Felder & Soloman (FS) model, and to detect any differences associated with the type of course and gender. Method: The study population (N=283; 190 women) consisted of first-year students attending the Medicine, Biomedical Sciences, Physical Therapy, Speech-Language Pathology, Nutrition and Metabolism, and Occupational Therapy courses, with 68.2% of them aged between 18 and 20 years. The students answered a sociodemographic characterization questionnaire and the FS Index of Learning Styles (ILS) questionnaire, which allowed determining the frequencies of the different learning styles and their associations with the type of undergraduate course and gender. Results: the student group showed a predominance of “Sensory”, “Visual”, “Reflective” and “Sequential”, learning styles, in the “Perception”, “Input”, “Processing” and “Understanding” dimensions of learning, respectively. There was no statistically significant difference in terms of learning styles, in any of the dimensions, that could be associated with the type of course and gender, although women showed a significant predominance of the “Reflective” style in the “Processing” dimension. Conclusion: It was not possible to establish significant differences between the different undergraduate courses in the health area, or between men and women, regarding the students’ predominant learning styles, although women showed a significantly higher frequency of the Reflective style. These findings must be considered when planning learning activities and, mainly, in pedagogical support, giving students the opportunity to learn about their learning styles and helping them to better adapt to the strategies employed in each institution.

title: Comparative analysis between portable spectrometer and integrating sphere spectrophotometer for measuring solar reflectance of tiles

description: Abstract Knowing the thermal properties of the surfaces of building envelope, such as the solar reflectance, is essential for the use of passive strategies to improve thermal performance of buildings. However, there is a lack of data for coatings produced in Brazil, because of the low availability of equipment and the need of specialized technicians. In order to simplify the access to these data, this work proposes the portable spectrometer ALTA II as an alternative to standardized measurement methods for solar reflectance of ceramic and fiber cement tiles. Therefore, solar reflectance data measured with a spectrophotometer with an integrating sphere were compared with those measured with the ALTA II for 39 tiles.Performance analyses of ALTA II from variations in the measurement method (with and without dark apparatus indoors and without apparatus outdoors) were inconclusive in determining the influence of the absence of a dark apparatus for the measurement on the selected samples. Despite the observed uncertainty, the research results showed strong correlation between the data measured on the ALTA II with the apparatus and with the spectrophotometer, indicating the spectrometer as an alternative for the solar reflectance measurement of these samples.
