title: Analysis of the guiding rules of the nurse technician’s practice in Brazil

description: ABSTRACT Objectives: to analyze the normative bases that guide the nurse technician’s practice, clarifying how the performance of this category happens. Methods: this is a qualitative study of exploratory and descriptive nature and of documentary type, held on the basis of the resolutions of the Brazilian Federal Nursing Council (Cofen). From a total of 364 resolutions published from 1975 to 2018, 15 accounted for the objective of the study and were therefore selected. Results: this study systematized two analytical categories: areas of practice of the nurse technician, according to Cofen resolutions; and description of the professional’s activities based on the resolutions. Final Considerations: the analysis of the normative bases that guide the nurse technician’s practice leads to the conclusion of a possible frailty of theoretical and normative content to justify the practice of these professionals.

title: CRITICAL VS ESTIMATED HEART RATE IN ELDERLY SUBJECTS

description: ABSTRACT Introduction: Heart rate (HR) has been a simple and easy-to-use physiological parameter widely used to determine exercise intensity. The critical power fatigue limit model, known as the critical heart rate (CHR), can be extrapolated to HR. However, an estimate for a CHR mathematical model has not yet been extrapolated for upper limb exercise in the elderly. Objective: To compare the mathematical model previously used to estimate CHR with the heart rate values at the critical power (CP) during arm-ergometer exercises in elderly subjects. Methods: After an initial maximum-incremental exercise test on a cycle arm-ergometer, seven elderly people performed four high-intensity constant-load tests to the limit of tolerance (Tlim), to determine CP and critical heart rate (CHR). For each power output, the heart rate of the last five seconds (HRlim) and total time to exhaustion (in minutes) were obtained. The slope coefficients of the regression lines between HRlim and Tlim were defined as CHR, and between Wlim and Tlim as CP. A square-wave test was performed on a different day, in the power determined as equivalent to CP, and the heart rate at CP (CPHR) was assessed. Results: The HR-Tlim relationship was found to be hyperbolic in all subjects, who were able to sustain upper-limb exercise at CP for 20 min. CP attained 66.8±9.4% of peak work rate in the ramp test. The real average HR measured in the CP test was strikingly similar to the CHR calculated by the mathematical model of PC (137.6±16.9 versus 139.7±13.3bpm, respectively, p=0.53). There was strong correlation between the real and the estimated CHR. Conclusion: This study indicated that the maximal sustainable exercise intensity can be based on a physiological variable such as HR, and the CHR test can define exercise endurance, which can be useful in performance assessment and training prescription.

title: Crotamine in Crotalus durissus: distribution according to subspecies and geographic origin, in captivity or nature

description: Abstract Background: Crotalus durissus is considered one of the most important species of venomous snakes in Brazil, due to the high mortality of its snakebites. The venom of Crotalus durissus contains four main toxins: crotoxin, convulxin, gyroxin and crotamine. Venoms can vary in their crotamine content, being crotamine-negative or -positive. This heterogeneity is of great importance for producing antivenom, due to their different mechanisms of action. The possibility that antivenom produced by Butantan Institute might have a different immunorecognition capacity between crotamine-negative and crotamine-positive C. durissus venoms instigated us to investigate the differences between these two venom groups. Methods: The presence of crotamine was analyzed by SDS-PAGE, western blotting and ELISA, whereas comparison between the two types of venoms was carried out through HPLC, mass spectrometry analysis as well as assessment of antivenom lethality and efficacy. Results: The results showed a variation in the presence of crotamine among the subspecies and the geographic origin of snakes from nature, but not in captive snakes. Regarding differences between crotamine-positive and -negative venoms, some exclusive proteins are found in each pool and the crotamine-negative pool presented more phospholipase A2 than crotamine-positive pool. This variation could affect the time to death, but the lethal and effective dose were not affected. Conclusion: These differences between venom pools indicate the importance of using both, crotamine-positive and crotamine-negative venoms, to produce the antivenom.

title: Changes in tactical behavior during small-sided and conditioned games performed within a training session

description: Abstract This study aimed to verify the acute effects of 3vs.3 soccer small-sided and conditioned games (SSCG) on the tactical behavior of youth soccer athletes within one training session. Twenty-four soccer athletes (U-13 and U-14 categories) from a professional club participated in the study. They played four 4-minute 3vs.3 SSCG with 4 minutes of passive recovery in-between. All SSCG were recorded and players’ tactical behavior was analyzed using the System of Tactical Assessment in Soccer. We compared the frequencies and percentages of successful tactical principles over the four 3vs.3 SSCG bouts performed within the training session. Results showed an increased number of defensive unity actions (p= 0.005; large effect size) and a higher percentage of successful defensive principles (p&lt;0.001; moderate effect size) in the fourth bout. We can conclude that players’ tactical behaviors change over the SSCG bouts performed within one training session. This suggests that players adapt their tactical behavior according to the tactical problems presented in the SSCG performed within the training session. We can suggest that the long-term improvement in the tactical skills of soccer athletes may be based on these small acute changes in tactical behavior observed in each training session.

title: EFFECTS OF A 20-WEEK PILATES METHOD PROGRAM ON BODY COMPOSITION

description: ABSTRACT Objective: The objective of this study was to evaluate whether there were changes in body composition after a 20-week (twice weekly) Pilates Method (PM) program when compared to a control group. Methods: This was a controlled quasi-experimental study in which 41 subjects (83.3% females, 16.7% males) aged between 28 and 58 years (mean age = 42.37±7.86 years) were divided into two groups (intervention or control group) and later evaluated. Body composition was measured with anthropometric techniques utilizing the following variables: weight, height, and 6 skinfold measurements. The PM intervention consisted of two weekly sessions, over a 20-week period. The minimal attendance for the program was 85%. Results: Significant differences were observed between the two groups for the sum of six skinfold measurements (p=0.01) and body fat percentage (p=0.004). Conclusion: Practicing the PM for 20 weeks seems to be an activity that can positively influence changes in body composition. Level of evidence III, non-randomized controlled cohort study.

title: [Serum dosage of the tumor marker Ca 15.3 in bitches presenting mammary neoplasia with the chemiluminescence method]

description: ABSTRACT The objective of the present study was to analyze the serum levels of the tumor marker Ca15.3 in healthy bitches and those with mammary neoplasms, correlating results with tumor type, clinical staging, time until presentation, and presence of ulceration and vascularization. For the study, 30 bitches with mammary tumors and 30 healthy bitches (control group) were selected. Histopathology was performed for identification of tumor type, and blood was collected for measurement of serum concentration of the marker via the chemiluminescence method using a commercial kit. A higher frequency of malignant neoplasms was observed (76.7%), with a higher quantity of carcinoma in mixed tumor (26.7%). Regarding serum concentration of the marker Ca15.3, there was no difference in serum values when comparing the means from bitches with neoplasia and healthy bitches, nor when comparing the other characteristics. The majority of results for serum concentration of Ca15.3, whether in bitches with neoplasia or in healthy bitches, was zero. It is concluded that the measurement of the marker Ca15.3 using the chemiluminescence method and commercial kits for humans did not offer significant results that would make this method or this marker a useful tool for patient monitoring and evaluation of the prognosis of bitches with mammary neoplasms.

title: Influence of cobalt ferrite on the magnetoelectric properties of thin films of bismuth ferrite deposited by spin coating

description: ABSTRACT The films composed of (1-x) BiFeO3- (x) CoFe2O4 varying the concentration (x = 0, 0.1, 0.2 and 0.3) were deposited by spin coating on Pt substrate (Pt / TiO2 / SiO2 / Si) from of 0.05 molar concentration precursors solutions, which were obtained by sol-gel method. Thin films characterization was made, the structure and the magnetoelectric properties were studied using X-ray diffraction, leakage current, dielectric constant, ferroelectric and ferromagnetic hysteresis curve. The XRD results show characteristic peaks with the formation of BiFeO3 and the growth of peaks belonging to CoFe2O4 with the increase of x. All samples reveal little leakage current, being the lowest of 10-10 A/cm2 for (0.8) BiFeO3- (0.2) CoFe2O4. The dielectric constant increased in the range from 102Hz to 105Hz then decreased due to dielectric relaxation, for all samples the dielectric loss is less than 4%. All fabricated films show remnants polarization and magnetization greater than 60 μC/cm2 and 30 emu/gr respectively.

title: DETECTING SPORTING TALENTS WITH Z-STRATEGY - CROSS SECTIONAL STUDY

description: ABSTRACT Introduction: Due to the relationship between early identification of physical and anthropometric characteristics above the population mean in children and adolescents, and success in sports, detecting potential sports talents should be broadly and systematically used as a strategy for the early identification of physical characteristics favorable to the sport in question. However, most studies do not use representative samples, or else they present talent detection without using valid scientific methods. This retrospective, comparative study therefore presents the identification of potential sports talents using the Z Strategy, calculated with anthropometric, neuromotor and physical fitness data. Objective: To identify physical abilities and anthropometric values above what are considered the normal ranges in a population of students in the 8th year of basic education, in Chile. Methods: The sample consisted of 9,429 students from public and private schools (50.9% boys). Data were obtained from a cross-sectional study conducted in 2013. Physical fitness and anthropometric data were recompiled through the Educational Quality Measurement System (Sistema de Medición de la Calidad de Educación – SIMCE) of physical education. The “Z Strategy” was used to detect sports talents by identifying values above the population mean. Results: In at least one variable, a total of 619 male and 623 female students with a standard deviation ≥2 (Z2) were detected. Conclusion: “Z Strategy” was able to detect sports talents of both sexes and of different ages. Level of evidence III; Retrospective comparative study.

title: Radiation therapy for advanced canine nasal planum squamous cell carcinoma: case report

description: ABSTRACT This case report describes the outcome of treatment of dogs with advanced (deeply invasive) nasal planum squamous cell carcinomas with palliative or definitive radiation therapy. All dogs were diagnosed with nasal planum squamous cell carcinoma by histopathology, and their owners declined aggressive surgery. Dogs were treated with a cobalt-60 unit, definitive-intent radiation protocol consisting of 15 daily fractions (Monday-Friday) of 2.8 Gy, and palliative radiation protocol consisting of 4 fractions of 8 Gy performed once a week. Three dogs had T3 tumors and three had T4 tumors according to the WHO staging system. Two dogs had tumor complete remission and four had tumor partial remission. Survival time of dogs submitted to radiation therapy was 95-417 days. Radiation acute side effects involved only mild epilation and cutaneous erythema in palliative protocols, and moist desquamation, epilation, mild rhinitis and oral mucositis in definitive-intent RT. Radiation therapy, especially palliative protocols, can be a treatment option for nasal planum squamous cell carcinoma in dogs, when the owner declines aggressive surgery. It may contribute to partial or complete tumor remission and better patient quality of life, even at advanced stages, leading to mild side effects.

title: Extragonadal malignant teratoma in a dog - case report

description: ABSTRACT Teratomas are neoplasms thought to arise from germ cells which usually occur within gonads and are rarely described on extragonadal sites. The present study reports a case of a 15 year old female mongrel dog with a lumbosacral tumor. The tumor was microscopically composed of embryonic tissues with areas containing atypical undifferentiated cells, leading to the diagnosis of a malignant teratoma. Malignant teratomas are uncommon tumors in domestic animals.
