title: Anthropometric indicators as predictors in determining frailty in elderly people

description: Abstract The scope of this article is to analyze anthropometric indicators as predictors in determining frailty in elderly people. This is a cross-sectional, family-based and analytical study. The survey was composed of 316 elderly subjects. The association between the anthropometric markers and frailty was tested using the Logistic Regression technique. However, the power of frailty diagnosis using anthropometric markers and the identification of the best cutoff points were evaluated using the parameters provided by the Receiver Operating Characteristic (ROC) curve. The anthropometric indicators of nutritional status: calf circumference, body mass index and corrected arm-muscle area are inversely associated with frailty. Thus, an increase in the values of these indicators is a protective factor against this syndrome. Analyzing body mass index and calf circumference simultaneously in order to perform a simpler screening for frail elderly people is recommended, as these indicators show good sensitivity and are easier to measure.

title: Number and magnitude: discussing the concept of measurement by means of a sixteenth-century mathematical instrument

description: Abstract: This paper presents some results of a study that valued manipulative conditions in the process of knowledge construction by handling a sixteenth-century mathematical instrument. The study was based on a problem-situation elaborated by epistemological and mathematical questions, which emerged from an interface built between the history of mathematics and teaching. The handling of this instrument triggered a series of actions that led teachers to reflect and discuss the very notion of magnitude, number and measurement. The results of the study suggest an epistemological gap between the observer who measures, the instrument that mediates the measuring, and the measured object. This gap compromises the proper understanding of measuring and the relationship between number and magnitude in measurement process.

title: Medical Doctors’ Knowledge of Libras in the Federal District and Deaf Patient Health Care

description: ABSTRACT In medical schools, the teaching of Brazilian Sign Language (Libras) is limited and this scenario may result in difficulties when dealing with an important portion of the population: the deaf. According to the Brazilian Institute of Geography and Statistics (IBGE), nearly 24% of the Brazilian population has some kind of deficiency; belonging to what are known as vulnerable groups. Deafness is among the most prevalent deficiencies, and the medical practice being unable to attend a deaf patient is a public health problem that requires further discussion. The objective of the present study was to evaluate medical doctors’ knowledge of Libras and their perception of attending to a deaf patient. A crosssectional and descriptive study was designed and 101 medical doctors of the Brazilian Public Health System (Sistema Único de Saúde, SUS) were randomly chosen in the Federal District and answered a structured survey. We interviewed medical doctors with a mean age of 41 years from 24 different medical specialties. 92.1% of them had seen at least one deaf patient in their clinical practice. 76.2% of them considered the knowledge of Libras relevant to their practice, but only one declared basic knowledge of the language. Most of the medical doctors reported uncertainty and discomfort when attending a deaf patient. A significant number of doctors had already seen a deaf patient in their clinical practice, and most considered the knowledge of Libras important, especially those under the age of 55 years. The feeling of discomfort when dealing with a deaf patient possibly arises from not knowing Libras and being unable to communicate with the patient properly. We emphasize the importance of learning Libras before or during medical school and other health-related courses. Being aware that the deaf patient deserves full health assistance is fundamental, and it may improve specialized learning of Libras and consequently result in a better doctor-patient relationship.

title: B-Type Natriuretic Peptide as a Predictor of Short-Term Mortality in On-Pump Coronary Artery Bypass Grafting

description: Abstract Objective: The present study refers to a determination of the preoperative B-type natriuretic peptide is a predictor of short-term all-cause mortality in patients undergoing on-pump coronary artery bypass graft surgeries. Methods: Two hundred and twenty-one patients undergoing on-pump coronary artery bypass graft surgeries were evaluated prospectively during a 30-day postoperative follow-up period. Serum B-type natriuretic peptide concentration was measured without a 24-hour period prior to the surgical procedure and the value obtained was correlated with a short-term all-cause mortality. Results: Data analysis showed that all-cause mortality rates were equal to 9.5% in 30 days. Accuracy analysis by the receiver operating characteristic curve found an ideal cut-off value of B-type natriuretic peptide equal to 150 pg/mL in relation to mortality (AUC=0.82, 95% CI=0.71-0.87, P&lt;0.001). Multivariate analysis showed that B-type natriuretic peptide value greater than or equal to 150 pg/mL (P=0.030, HR=3.99, 95% CI=1.14-13.98) was an independent predictor of all-cause mortality in a 30-day follow-up period. Conclusion: Preoperative serum B-type natriuretic peptide concentration is an independent predictor of short-term all-cause mortality in patients undergoing coronary artery bypass grafting with cardiopulmonary bypass.

title: Species inventory of aquatic macrophytes in the last undammed stretch of the Upper Paraná River, Brazil

description: Abstract The last undammed stretch of the Upper Paraná River in the Brazilian territory is, to date, not completely inventoried, which rises concerns given the rapid rates of species extinctions. Aim Here, we provide an inventory of macrophyte taxa recorded in the last undammed 230 km stretch of the Upper Paraná River. Methods We inventoried macrophyte taxa in 27 sampling stations including lakes, the main channel of the river, and the tributary confluences in November 2013 and in May and November 2014. Macrophyte were sampled in littoral zones. We explored taxonomic and life form aspects of the recorded species. We used species accumulation curves and ordination techniques to summarize the variation in richness and composition of macrophyte species. Results We recorded 71 macrophyte taxa in 35 families. Most species were emergent, amphibian, free-floating, and rooted submerged. At the main channel of the Upper Paraná River, Eichhornia azurea, E. crassipes, and Paspalum repens represented the most frequent species. The most frequent species in the tributary confluences were Ludwigia sp., E. azurea, and Polygonum ferrugineum, while in lakes, Ludwigia sp., Oxycaryum cubense, and E. azurea were the most representative taxa. In regard to macrophyte composition, the invasive Hydrilla verticillata mostly influenced sites in the Upper Paraná River, in the ordination space, while floodplain lakes were mostly characterized by the presence of species such as Scleria melaleuca, Panicum maximum, and Thelypteris sp., among others. Conclusions Our study indicates that the last undammed stretch of the Upper Paraná River contains a large number of macrophyte species, suggesting that this stretch is an important area for the conservation of macrophyte species. In addition, the occurrence of invasive species (e.g., Hydrilla verticillata) within the investigated stretch deserves attention in terms of potential impacts for which management action may be necessary.

title: Survival outcome among patients with Ewing’s sarcoma of bones and joints: a population-based cohort study

description: ABSTRACT BACKGROUND: The aim here was to elucidate the current survival condition of patients diagnosed with Ewing’s sarcoma of the bones and joints and determine independent risk factors associated with the prognosis. DESIGN AND SETTING: Retrospective cohort study based on the Surveillance, Epidemiology and End Results (SEER) database in the United States. METHODS: We identified 397 patients who were diagnosed with Ewing’s sarcoma of the bones and joints between January 2004 and December 2013. The multivariate Cox proportional hazards model was used to determine factors associated with the risk of death by adjusting for various factors. RESULTS: The one, two and five-year disease-specific survival rates were 89.08%, 78.08% and 62.47%, respectively. The factors related to death were age (≥ 18 years versus &lt; 18 years; hazard ratio, HR = 1.77; 95% confidence interval, CI: 1.38-2.31); tumor site (extremity versus spine and pelvis; HR = 2.03; 95% CI: 1.31-2.62); tumor size (&gt; 10 cm versus ≤ 10 cm; HR = 1.78; 95% CI: 1.34-2.56); and type of treatment (surgery alone versus radiotherapy with surgery; HR = 0.51; 95% CI: 0.38-0.89; or radiotherapy alone versus radiotherapy with surgery; HR = 1.61; 95% CI: 1.10-2.39; or no treatment versus radiotherapy with surgery; HR = 1.86; 95% CI: 1.23, 2.58). CONCLUSIONS: Patients with Ewing’s sarcoma showed poor survival in situations of age ≥ 18 years, tumor size &gt; 10 cm, receiving radiotherapy alone and receiving no treatment. Patients undergoing surgery alone had better survival.

title: Sociabilities, edition, education: The Brazilian Literature Yearbook as an education project (1937-1944)

description: ABSTRACT This article aims to analyze the periodic Annuário Brasileiro de Literatura (Brazilian Literature Yearbook, ABL), published between 1937 and 1944, as a place of sociability and as an education organ of Brazilian intellectuality. ABL became in the period, one of the most important and influent Brazilian periodic publications. In the text, we intend to demonstrate that it was part of an investment for the construction of national unity, of an exchange among several intellectual agents (writers, editors, journalists, etc.) and an effort to put Brazil in a group of civilized nations. The periodic proposed the conciliation of intellectuality in favor of national unity, while at the same time reaffirming that such unity could not do away with the richness of our historical, cultural and geographic diversity. Finally, we pointed that the ABL aimed to educate and mobilize the intellectuals; however, they did not stop themselves from looking at school education as a condition, or an obstacle to the amplification of the editorial market - and, therefore, of the clarification of the Brazilian population.

title: The Evaluation of Nosocomial Infections in Pediatric Patients with Extracorporeal Membrane Oxygenation Support

description: Abstract Introduction: Extracorporeal membrane oxygenation (ECMO) has become a standard technique over the past few decades in intensive care unit (ICU). Objective: A review of pediatric patients who received ECMO support in the pediatric cardiac ICU was conducted to determine the incidence, risk factors and causal organisms related to acquired infections and assess the survival rates of ECMO patients with nosocomial infections. Methods: Sixty-six patients who received ECMO support in the pediatric cardiac ICU between January 2011 and June 2014 were included in the study. Demographic, echocardiographic, hemodynamic features and surgical procedures were reviewed. Results: Sixty-six patients received a total of 292.5 days of venoarterial ECMO support. Sixty were postoperative patients. Forty-five patients were weaned from ECMO support with an ECMO survival rate of 68.2%. The rate of infection was 116.2/1000 ECMO days. Prolonged ICU stay, duration of ventilation and ECMO were found associated with development of nosocomial infection and only the duration of ECMO was an independent risk factor for nosocomial infections in ECMO patients. Conclusion: The correction of the underlying process leading to ECMO support and shortening the length of ECMO duration together with stricter application of ECMO indications would improve the infection incidence and hospital surveillance of the patient group.
