title: Puerperal sepsis caused by liver abscess: case report

description: Abstract Introduction: sepsis is a serious public health problem, affecting millions of people in the world each year, with a high mortality rate (one out of four patients) and an increasing incidence. Sepsis is one of the main causes of maternal mortality and an important cause of admission to obstetric intensive care units. Case description: In this study, the authors report the case of a woman having been submitted to cesarean section three days before presenting clinical signs of sepsis and septic shock caused by a liver abscess. The patient had a set of complications secondary to shock, such as thrombocytopenia, coagulopathy, toe ischemia and acute kidney failure. The patient had cholelithiasis and recurrent pain in the right hypochondrium during pregnancy. During hospitalization, the mechanism involved in the development of hepatic abscess was infection of the biliary tract. The patient was treated in an obstetric intensive care unit with antibiotics and drainage of the liver abscess. Progress was favorable and the patient was discharged in good health. Discussion: pyogenic liver abscess during pregnancy and puerperium is a serious condition which represents a diagnostic and therapeutic challenge, with few cases reported. The normally nonspecific clinical and laboratory findings can lead to a late diagnosis, which increases the risk of maternal morbidity and mortality.

title: Digital Skills and Giftedness: a Comparative Analysis of Technology Use

description: ABSTRACT In the face of the popularization of Digital Information and Communication Technologies (TDIC) and the ease of access to the Internet we have today, we cannot ignore that today’s students are immersed in a digital culture, have characteristics and different behaviors, are influenced by the huge flow of information available on the Internet and the immediate interactivity of digital resources. Considering the skills of these students on seeking, selecting and sharing information, it is possible to think and investigate how the early and/or gifted students relate to technology. We consider the TDIC as important intellectual tools for the enrichment of gifted students, however, it is necessary to identify the skills that are specific to these students and those that are common to all digital natives to guide and help them develop their digital competencies. Thus, the aim of this study is to verify the quality of the actions of digital native students with and without early and/or gifted behavior regarding the TDIC. As for the method, this is a comparative study that describes the use of the early and/or gifted students in their behavior (G1) and students without this specificity (G2), from the initial and final years of elementary school, make of the TDIC. We noted that although the skills and digital competences of students in both groups are similar, students of G1 showed more quality in their actions. We noted that G1 were more aware of the actions, resulting in a bigger difference between the students in the early years of elementary school, attributed to the characteristics of phenomenon of precocity.

title: A pursuit for physics questions from ENEM less associated with socioeconomic status

description: The National High School Exam is the second largest large-scale exam in the world. In Brazil, the students’ performance in the test is the main selection criteria to access higher education. The association between student performance and socioeconomic status in large-scale exams has been investigated by researchers in the education field since the late 1960s. To overcome this influence, researchers need find new alternatives. Therefore, this work presents a research that aims to analyze physics questions in ENEM in order to find examples less associated with context variables. The use of questions with low association with socioeconomic status in the ENEM can lead this assessment to be more socially fair, after all, it would select students mostly by proficiency in a certain area of knowledge and not by socioeconomic status. For this, in order to better define the socioeconomic level of the students participating in the exam, we carried out a Full-Information Factor Analysis (FIFA) on the socioeconomic questionnaire. The results of the analysis lead to seven groups of bivariate socioeconomic levels, obtained by the mix of economic and institutionalized cultural capitals (one of the dimensions of bourdieusian cultural capital). Then, we obtained the proportion of correct responses in the physics questions for each of the capital levels. The questions with lower variability in these proportions between groups are the least associated with context variables. In this article, we identified and analyzed items with these characteristics in the 2009, 2012 and 2015 ENEM tests.

title: Institutional and social enablers for governance of environmental risks at the local scale. Analysis of Chilean municipalities

description: Abstract The Latin American context of exposure to environmental risks demands a better understanding of the institutional factors that impact on local environmental management. Supported by mixed research methods, this study examines hypotheses on relationships between political, institutional, and social factors and municipal environmental management in the empirical context of Chilean municipalities. The results suggest that the combination of political factors, institutional arrangements and capacities, and relationships with society explain different municipal behaviors.

title: Bat necrophagy by a whip-spider (Arachnida, Amblypygi, Phrynidae) in a cave in the eastern Brazilian Amazon

description: ABSTRACT Amblypygids are among the main predators in the ferriferous caves in Carajás National Forest, state of Pará (Amazon region of Brazil). One of the most common amblypygid species in this region is Heterophrynus longicornis (Butler 1873), and its most frequent prey are crickets of the family Phalangopsidae, which are abundant in the caves of Pará. Because they are primarily predators, necrophagy by amblypygids is not frequent in nature, and there are only two literature records of necrophagy of bats by Amblypygi. On December 11th, 2013, we observed an individual H. longicornis eating a bat carcass in a Pará ferriferous cave. The amblypygid exhibited considerable interest in the bat’s carcass, and it did not interrupt its meal even when lamps or a camera’s flash were pointed in its direction. The availability of nutrients in the carcass must promote this opportunistic behavior in caves, especially considering the habitual scarcity of trophic resources in underground environments when compared to epigean environments.

title: Self-perceived quality of health and satisfaction by elderly seen by the Family Health Strategy team

description: ABSTRACT Objective: To verify the profile of elderly followed up by Family Health Strategy teams and the influence of self-reported chronic diseases on demographic variables, describing self-perception and satisfaction with quality of health. Methods: This is a cross-sectional population- based study carried out with 301 elderly residents in two areas of a city in southern Brazil. Data were collected through a questionnaire based on the Health, Well-Being, and Aging Study adapted by researchers, and a playful scale to assess satisfaction with health. For the statistical analysis, the χ2 test was used (p&lt;0.05). Results: Regarding cognitive assessment, the majority was classified as independent (86.4%), not requiring caregiver assistance to answer the questionnaire. The population was predominantly female (55.8%), White (64.8%), married (51.2%), and catholic (82.1%). A total of 47.5% considered their current health status as regular. Regarding satisfaction with health, 72.4% were happy, even reporting having at least one chronic health problem (58.5%). Conclusion: The presence of chronic diseases was reported by most respondents, and the practice of self-medication is significantly more frequent among the aged. Nevertheless, the degree of satisfaction with their health status was predominantly positive, both related to the previous year and compared to others of the same age.

title: Postmortem interval estimation based on Chrysomya albiceps (Diptera, Calliphoridae) in a forensic case in the Andean Amazon, Caquetá, Colombia

description: ABSTRACT This is the first application of forensic entomology in a case involving a human corpse found in the urban area of the Municipality of Florencia, Caquetá, Colombia, in the Piedemont of the Colombian Amazon. Three days after removing the body from the scene, pupae and puparia were collected and identified as Chrysomya albiceps (Wiedemann, 1819) (Diptera, Calliphoridae). The postmortem interval was estimated on the basis of previously published data and verified through accumulated degree hours (ADH) and intrapuparial development. The estimated minimum postmortem interval was of 229 hours (9.5 days).

title: Yolk sac primary tumor of mediastino: a rare case in a young adult

description: ABSTRACT Germ cell tumors are rare neoplasms that mostly occur in the gonads, although they can also affect other body sites, especially the anterior mediastinum (50 to 70% of all extragonadal germ cell tumors). We report a case of a primary mediastinal yolk sac tumor, a rare and aggressive germ cell tumors subtype. This was a 38-year-old man who was admitted to Hospital do Servidor Público Estadual “Francisco Morato de Oliveira”, complaining about dyspnea and dry cough for 1 year. The computed tomography scan of his chest revealed a large mass in the anterior mediastinum with heterogeneous enhancement to the contrast associated with pleural effusion. There were also high serum levels of alpha-fetoprotein. After neoadjuvant chemotherapy, the patient underwent surgical resection of the mass, followed by pathological examination, which confirmed a primary mediastinal yolk sac tumor, a nonseminomatous subtype of germ cell tumors. Primary mediastinal yolk sac tumors have poor prognosis, despite advances in therapy with surgical resection and cisplatin-based chemotherapy. This poor prognosis is due to the degree of invasion and unresectability in most patients by the time of the diagnosis.

title: Heat Treatment Effects on ASTM A890/A 890M GR 5A Super Duplex Stainless Steel Passivity

description: Heat treatment can modify the corrosion resistance of stainless steels. Thus, the corrosion behavior of ASTM A890/A 890M GR 5A super duplex stainless steels (SDSS) has been investigated in aqueous 60,000 ppm NaCl solution by several electrochemical tests. The specimens were aged for 2, 10, 50 and 100 hours at 475 ºC. Potentiodynamic polarization studies showed that, when the corrosion potential comes to the passivation state, a peak current is detected at about 400 mV vs. Ag/AgCl, with a strong influence on the film stability. The peak current value increased with the aging time; the highest peak value was for the sample aged for 100 h. Three potentials were chosen from the polarization curves in order to evaluate the sample/film/solution behavior and their changes over the passivation range. The results indicate that the passive film was degraded with the increase of the aging time. In addition, the results of the corrosion tests were compared with the evolution of the mechanical properties of the steels by the Vickers microhardness test.
