title: Zygomatic arch fracture in a dog treated with Veterinary Cuttable Plate - case report

description: ABSTRACT The purpose of this paper is to describe a case of a right zygomatic arch fracture in a 5-year-old male Labrador Retriever diagnosed with aid of 3D Computed Tomography reconstruction. Because of the depressed fracture and interference with the eyeball, surgical repair of the right zygomatic arch fracture was performed with open reduction and stabilization with an 11-hole, 2.7mm Veterinary Cuttable Plate. Radiographs taken 60 days after surgery revealed that fracture healing occurred without complications with improved function and cosmetic appearance. Ninety days after surgery the patient was clinically discharged.

title: Survival and Risk Factors Among Dialytic Acute Kidney Injury Patients After Cardiovascular Surgery

description: Abstract Objective: Acute kidney injury (AKI) is a frequent postoperative complication after cardiovascular surgery. It has been described as a predictor of decreased survival rates, but how dialysis decreases survival when initiated on the postoperative period has yet to be determined. To analyze the survival of patients who presented postoperative AKI requiring dialysis up to 30 days after cardiovascular surgery and its risk factors is the aim of this study. Methods: Of the 5,189 cardiovascular surgeries performed in a 4-year period, 157 patients developed AKI requiring dialysis in the postoperative period. The Kaplan-Meier survival curve and log-rank test were used in the statistical analysis to compare the curves of categorical variables. P-value&lt; 0.05 was considered significant. Results: Patient average survival was 546 days and mortality was 70.7%. The need for dialysis on the postoperative period decreased late survival. Risk factors for decreased survival included age (P&lt;0.001) and postoperative complications (P&lt;0.0003). Conclusion: The average survival was approximately one year among dialytic patients. Age and postoperative complications were risk factors that determined decreased survival.

title: Determination of constraint forces in holonomic classical systems: critical analysis of three methods

description: Abstract In this work, we critically analyze the peculiarities and potentialities of three approaches for the calculation of constraint forces in classical holonomic systems, namely, the Newtonian formalism, the Lagrangian formalism and a third mixed method developed by Brazilian physicist Nivaldo A. Lemos [1]. Analyzing the solutions of three classic problems by each of these methods, we conclude that the number of dimensions and the number of constraints of the problem influence in the efficiency of the methods, which provided the establishment of a criterion for the choice of formalism to be used.

title: Reproductive parameters after induction of estrus with different ranges of the vaginal device in acyclic Toggenburg goats

description: ABSTRACT This study aimed to evaluate the sexual behavior and the ovulatory dynamics of Toggenburg goats after induction of synchronized estrus by an intravaginal progesterone device for six, nine and twelve days. At the device insertion and 24 h before the device removal, 5mg of dinoprost and 200 UI of eCG was administered, respectively. The ovulatory dynamics was assessed by ultrasound every 8 h, while the sexual behavior was observed every 12 h. All goats showed estrus. The intervals from device removal to estrus were 29.5 ± 9.7, 34.0 ± 6.0 and 32.4 ± 7.7h to G6days, G9days and G12days, respectively. Iqually, it was found difference (P&lt;0.05) among G6days and the other groups. The duration of estrus differed (P&lt;0.05) among the G6days (36.0 ± 12.6) and the other two groups (G9days: 31.2 ± 14.3; G12days: 33.4 ± 8.6). The ovulation rate (81.0%; 89.5% and; 71.4%); the interval from device removal to ovulation (50.5 ± 11.4; 46.3 ± 5.9 and; 46.7 ± 8.3), the diameter of the largest follicle (6.6 ± 0.3; 6.6 ± 0.9 and; 6.9 ± 0.8), diameter of the second largest follicle (6.4 ± 0.7; 6.6 ± 0.8 and; 6.8 ± 0.6) and the number of ovulations (1.5 ± 0.6; 1.7 ± 0.6 and; 2.0 ± 0.9) for G6days, G9days and G12days, respectively, were similar (P&gt;0.05). All treatments were effective for the induction of synchronized estrus in Toggenburg goats, working jointly with the reproductive and productive efficiency of these animals.

title: Estrus induction in agoutis (Dasyprocta leporina) using protocols based on prostaglandin isolated or in association to GnRH analogue

description: ABSTRACT We compared the efficiency of protocols for estrus induction in agoutis. Five females received double intraperitoneal administration of cloprostenol (5µg) on a 2-days interval; other five females were treated with intravulvar administration of 30µg gonadotrophin release hormone analogue (GnRH associated to intraperitoneal administration of 5µg cloprostenol after seven days and a new administration of GnRH analogue after two days. Every 3 days, the agoutis’ reproductive cycle was monitored by blood collection for hormonal analysis, ovarian ultrasound and vaginal cytology. Two females, originally in luteal phase, that received isolated prostaglandin presented estrous signs at 3 and 6 days after the second drug administration. From the females that received the association, two that were originally in luteal phase presented estrus at 4 days after treatment, and one other presented estrus only after 10 days. There was no significant statistical difference regarding the efficiency of treatments for estrus induction (P&gt;0.05). We conclude that, according to the protocols tested in the study, the use of isolated prostaglandin or its association to GnRH analogue for estrus induction in D. leporine shows an efficiency limited to the females that were in luteal phase in the beginning of the treatment.

title: Endovascular treatment of acute gastrointestinal bleeding from a large splenic artery pseudoaneurysm: case report and literature review

description: Abstract Pseudoaneurysm of the splenic artery is a rare entity, with little more than 150 cases described in the literature. Pancreatitis is the most common etiology, followed by trauma. In contrast with true aneurysms, pseudoaneurysms are frequently symptomatic, with a 47% risk of rupture and 90% mortality if left untreated. We describe the case of a 48-year-old female patient who suffered a gastrointestinal hemorrhage associated with acute-on-chronic pancreatitis. During workup, endoscopy revealed signs of recent bleeding and magnetic resonance angiography of the abdomen showed a large pseudoaneurysm of the splenic artery. The patient underwent endovascular treatment with microcoil embolization and no further bleeding episodes occurred. Endovascular treatment is now an effective option with low morbidity and mortality and success rates in the range of 79-100%, making it a viable technique for patients with active abdominal inflammation. We conducted a review of endovascular techniques and embolization agents used to treat this pathology.

title: Inequalities Handling in Chilean Curriculum and School Texts

description: Abstract In this paper, we make an analysis of inequality handling, including both: the Chilean curriculum, through its plans and programs, and school texts. It has been decided to work on an exploratory research that follows a methodology of qualitative analysis, where the mathematical object will be equated with a complexity scheme of its own, allowing a visual analysis of what happens in Chile. Within the findings, we reveal some differences in the teaching progression for mathematical object under study, that is to say, the treatment given to the object in different courses would not cover it in its entirety. The missing contents could be addressed in classroom planning for every teacher with the aim of improving learning processes. Moreover, it is important to mention that the study process explained in this research can be also applied in the analysis of other mathematical objects.

title: A Methodological Design for Teacher Conceptions about Students Production by Using Semiotic Representation and Dimensions of Teacher's Knowledge

description: Abstract Our goal in this study is to present a methodological design for the analysis of empirical data in a qualitative research. To achieve that purpose, we used results of a previous research about mathematics problem solving, in which high school students were asked to solve a trigonometry question with two items. In the present work, questionnaires were answered by twenty high school teachers, who were asked to characterize the kind of the most representative errors found in that research, as well as to propose ways of intervention in mathematics teaching that could stimulate the students to critically think about their errors, in order to overcome them. The teachers’ answers were analysed upon the light of two theoretical frameworks: the first deals with mathematical learning by using semiotic analysis, as proposed by Duval, and the second one is related to the teacher's knowledge, according to Shulman. From this analysis, we proposed a methodological design to the qualitative analysis of teaching activities in the pedagogical approach of problem solving in mathematics.

title: Uterine Artery Doppler in Screening for Preeclampsia and Fetal Growth Restriction

description: Abstract Objective To perform a comprehensive review of the current evidence on the role of uterine artery Doppler, isolated or in combination with other markers, in screening for preeclampsia (PE) and fetal growth restriction (FGR) in the general population. The review included recently published large cohort studies and randomized trials. Methods A search of the literature was conducted usingMedline, PubMed, MeSH and ScienceDirect. Combinations of the search terms “preeclampsia,” “screening,” “prediction,” “Doppler,” “Doppler velocimetry,” “fetal growth restriction,” “small for gestational age” and “uterine artery” were used. Articles in English (excluding reviews) reporting the use of uterine artery Doppler in screening for PE and FGR were included. Results Thirty articles were included. As a single predictor, uterine artery Doppler detects less than 50% of the cases of PE and no more than 40% of the pregnancies affected by FGR. Logistic regression-based models that allow calculation of individual risk based on the combination of multiple markers, in turn, is able to detect ~ 75% of the cases of preterm PE and 55% of the pregnancies resulting in small for gestational age infants. Conclusion The use of uterine artery Doppler as a single predictive test for PE and FGR has poor accuracy. However, its combined use in predictive models is promising, being more accurate in detecting preterm PE than FGR.

title: Serum concentration of progesterone, pH of the vagina and body morphometryof pregnant deer (Cervus unicolor)in captivity

description: ABSTRACT The aim was to study pregnant cervus in captivity, to obtain body morphometric data, serum progesterone concentrations, and pH of the vagina. Females of cervus (Cervus unicolor), (n=8) between 2 and 3 years old were used in November during breeding season. After sedation, in one collection, the following was measured: body weight 54.50 ± 18.70kg, body length 1.21 ± 0.16m, height at withers 0.75 ± 0.08m, thoracic perimeter 0.84 ± 0.12m, and body mass index 97.32 ± 10.50kg / m2. After sedation, blood samples were collected to measure progesterone concentration by radioimmunoassay and the use of an indicator tape to obtain the pH of the vagina was performed eight times at four day intervals in the eight females, in a total of 64 samples for each exam. Data were analyzed, and significance was at 5%. There were no differences (P&gt; 0.05) between measurements for serum progesterone concentrations and pH of the vagina. The correlations between body weight, progesterone, pH, and body mass index were not significant (P&gt; 0.05). There was no significant oscillation of progesterone concentration and pH of the vagina in the pregnancy period studied.

title: Investigation of Salmonella spp. in exotic and native Psittaciformes kept in captivity in the central region of Rio Grande do Sul

description: ABSTRACT Infectious diseases are known to cause decline in wildlife population and some of them may represent a threat to public health. This study aimed to investigate the occurrence of Salmonella spp. in exotic and native Psittaciformes kept in captivity in the central region of Rio Grande do Sul, Brazil, and to comparing the results obtained through the conventional bacteriological method and the polymerase chain reaction (PCR), using fecal matter collected from the environment, avoiding the containment stress. From August to September 2016, samples of fresh feces were collected from 90 cages in two breeding grounds, representing 180 birds. According to both analysis techniques the samples were negative for Salmonella spp., however, bacteria from the Enterobacteriaceae family: Escherichia coli, Cedecea sp. and Citrobacter freundii were detected. Continuous monitoring of breeding grounds is important since the pathogen investigated can be found in carrier birds and manifest itself in stressful situations presenting risks such as zoonosis and reduced bird health.
