title: Supplementation with arginine in the diet of Nile tilapia reared in net cages

description: Abstract: The objective of this work was to evaluate the effect of dietary arginine concentrations on the health status of Nile tilapia (Oreochromis niloticus) cultivated in cages. The experiment was carried out in a completely randomized design with four treatments (2.3, 2.9, 3.5, and 4.1% arginine in dry matter) and three replicates, in 12 net cages of 8 m3, containing 4,000 sexually reverted tilapia (63±20 g, at 500 fish m-3). Fish productive performance and health were evaluated. Biochemical, hematological, and immunological parameters, as well as the morphological aspects of gills and liver, were evaluated. Arginine inclusion did not cause significant differences in fish growth performance. However, arginine supplementation at 3.5% concentration improved the biochemical parameters and leucocyte counts, consequently improving the immune system. The arginine concentration of 4.1% caused lipid degeneration, shown by the increase of alanine aminotransferase and the decrease of albumin, urea, lactate, and glucose. Arginine supplementation above 2.3% and below 3.5%, in the diets of tilapia reared in cages, improves fish immune system, without adverse morphological and physiological effects.

title: Association of Platelet to Lymphocyte and Neutrophil to Lymphocyte Ratios with In-Hospital Mortality in Patients with Type A Acute Aortic Dissection

description: Abstract Objective: To evaluate the relationship between neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) with in-hospital mortality in type A acute aortic dissection (AAD). Methods: A total of 96 patients who presented to the emergency department between January 2013 and June 2018 with a diagnosis of type A AAD were enrolled in this study. White blood cell count subtypes such as NLR and PLR were calculated at the time of admission. The end point was in-hospital mortality. Results: Of the 96 type A AAD patients included in this analysis, 17 patients (17.7%) died during hospitalization. NLR and PLR were significantly elevated in patients with type A AAD (P&lt;0.001 and &lt;0.001, respectively). Based on the receiver operating characteristic curve, the best NLR cut-off value to predict in-hospital mortality was 9.74, with 70.6% sensitivity and 76.8% specificity, whereas the best PLR cut-off value was 195.8, with 76.5% sensitivity and 78.1% specificity. Conclusion: Admission NLR and PLR levels were important risk factors and independently associated with in-hospital mortality of type A AAD patients.

title: Prevalence of Cronobacter spp. in various foodstuffs and identification by multiplex PCR

description: Abstract Cronobacter spp. are opportunistic pathogens isolated from many different type of food and environmental samples and may cause serious health problems and even death in newborns, children and elders. The purpose of the study was to determine occurrence and prevalence of Cronobacter spp. in animal originated food, ready-to-eat food, fruits and vegetables, sold in Istanbul and its vicinity and to perform molecular typing of the isolated agents by multiplex PCR. Analyses were conducted on a total of 219 food samples including 11 confectionary, 50 fruits and vegetables, 52 dairy products, 50 meat and meat products and 56 ready-to-eat food. Suspected isolates were validated by PCR targeted to gyrB gene and multiplex PCR was performed for identification. Overall analyses revealed a prevalence of 5.48% for Cronobacter spp. in all food products assessed. Prevalence of the bacteria was 9%, 1.9% and 17.8% in confectionary, dairy products and ready-to-eat food, respectively whereas no bacteria were detected in fruits and vegetables, meat and meat products. Out of a total of 12 isolates determined, 8 (66%), 3 (25%) and 1 (8%) were identified as C.sakazakii, C.muytjensii and C.malonaticus , respectively and nine isolates belonged to cereal-based balls (meatless cig kofte).

title: New-Onset Atrial Fibrillation in St-Segment Elevation Myocardial Infarction: Predictors and Impact on Therapy And Mortality

description: Abstract Backgrund: New-onset atrial fibrillation complicating acute myocardial infarction represents an important challenge, with prognostic significance. Objective: To study the incidence, impact on therapy and mortality, and to identify predictors of development of new-onset atrial fibrillation during hospital stay for ST-segment elevation myocardial infarction. Methods: We studied all patients with ST-elevation myocardial infarction included consecutively, between 2010 and 2017, in a Portuguese national registry and compared two groups: 1 - no atrial fibrillation and 2 - new-onset atrial fibrillation. We adjusted a logistic regression model data analysis to assess the impact of new-onset atrial fibrillation on in-hospital mortality and to identify independent predictors of its development. A p value &lt; 0.05 was considered significant. Results: We studied 6325 patients, and new-onset atrial fibrillation was found in 365 (5.8%). Reperfusion was successfully accomplished in both groups with no difference regarding type of reperfusion. In group 2, therapy with beta-blockers and angiotensin-conversion enzyme (ACE) inhibitors/angiotensin receptor blockers (ARBs) was less frequent, 20.6% received anticoagulation at discharge and 16.1% were on triple therapy. New-onset atrial fibrillation was associated with more in-hospital complications and mortality. However, it was not found as an independent predictor of in-hospital mortality. We identified age, prior stroke, inferior myocardial infarction and complete atrioventricular block as independent predictors of new-onset atrial fibrillation. Conclusion: New-onset atrial fibrillation remains a frequent complication of myocardial infarction and is associated with higher rate of complications and in-hospital mortality. Age, prior stroke, inferior myocardial infarction and complete atrioventricular block were independent predictors of new onset atrial fibrillation. Only 36.7% of the patients received anticoagulation at discharge.

title: Chemical characterization and bioactive compounds of an unconventional vegetable - Erechtites valerianifolia (Wolf) DC.

description: Abstract Erechtites valerianifolia (Wolf) DC is an unconventional vegetable found in the Brazilian Atlantic Forest. Is consumed in high proportions by the population living in this biome. The objective of this study was to investigate the general chemical composition, occurrence and content of carotenoids, vitamins (C and E) and minerals in this vegetable. By the micro-Kjeldhal method it was determined proteins. It was determined total dietary fiber (TDF) by non-enzymatic gravimetric method. Carotenoids and vitamins were determined by high performance liquid chromatography (HPLC). In inductively coupled plasma-atomic emission spectrometry (ICP-AES) it was determined minerals. E. valerianifolia presented concentrations of TDF (3.7 g 100 g-1), ash (0.9 g 100-1), lipids (1.4 g 100-1), carbohydrates (2.9 g 100-1), proteins (1.3 g 100-1), caloric density (29.2 kcal 100-1), Vit. A (373.9 µg 100-1 RAE), K (561.2 mg 100-1), Ca (79.5 mg 100-1) and Fe (21.6 mg 100-1). It is considered that this vegetable is source of Ca, good source of fiber and K, and an excellent source of pro-vitamin A, Mn, Se, Fe, Mo and Cu, which may reduce food and nutritional insecurity in the population, mainly in the region where this species is found.

title: Right Atrium Tumor Extension Through the Inferior Vena Cava. Considerations About Nine Cases Operated Under Cardiopulmonary Bypass

description: Abstract Introduction: Adrenocortical and renal cell carcinomas rarely invade the right atrium (RA). These neoplasms need surgical treatment, are very aggressive and have poor prognostic and surgical outcomes. Case series: We present a retrospective cohort of nine cases of RA invasion through the inferior vena cava (four adrenocortical carcinomas and five renal cell carcinomas). Over 13 years (2002-2014), nine patients were operated in collaboration with the team of urologists. Surgery was possible in all patients with different degrees of technical difficulty. All patients were operated considering the imaging examinations with the aid of CPB. In all reported cases (renal or suprarenal), the decision to use CPB with deep hypothermic circulatory arrest (DHCA) on surgical strategy was decided by the team of urological and cardiac surgeons. Conclusion: Data retrospectively collected from patients of public hospitals reaffirm: 1) Low incidence with small published series; 2) The selected cases did not represent the whole historical casuistry of the hospital, since they were selected after the adoption of electronic documentation; 3) Demographic data and references reported in the literature were presented as tables to avoid wordiness; 4) The series highlights the propensity to invade the venous system; 5) Possible surgical treatment with the aid of CPB in collaboration with the urology team; 6) CPB with DHCA is a safe and reliable option; 7) Poor prognosis with disappointing late results, even considering the adverse effects of CPB on cancer prognosis are expected but not confirmed.

title: Giant Aneurysm of The Non-Coronary Sinus of Valsalva

description: Abstract Aneurysms of the sinuses of Valsalva are defined as dilatation of the aortic root region between the aortic annulus and the sinotubular junction. Isolated aneurysms of the sinus of Valsalva are rare cardiovascular pathologies. They may be congenital, especially secondary to connective tissue disorders or in conjunction with congenital cardiac defects, or acquired such as secondary to infections or trauma. Small sized aneurysm without rupture in asymptomatic patients may be followed; however, latter cases require intervention and surgery is the gold standard treatment modality. In this report, a 41-year-old male patient was reported with giant aneurysm of the non-coronary sinus of Valsalva whom underwent aortic root sparing surgical aortic sinus of Valsalva reconstruction.

title: Seroprevalence of Zika virus among blood donors before the epidemic in Barranquilla, Colombia, 2015-2016.

description: Abstract: The first cases of Zika virus infection in Colombia were reported and confirmed in October 2015. The objective of the study was estimate the seroprevalence of ZIKV infection during the pre-epidemic phase in Barranquilla, Colombia, and demonstrate the presence of virus before the Colombian Ministry of Health confirmed the first case. We conducted a descriptive study of the seroprevalence of Zika virus in 390 samples obtained from a blood bank located in Barranquilla, Colombia - a city endemic for dengue, and with a recent history of a Chikungunya disease epidemic. The serum pools were tested using Euroimmun ZIKV ELISA kit. Seroprevalence of Zika virus IgG were: May 2015: 0%, June and July 2015: 2.62% (95% CI = 0.28-12.13) and August 2015: 5.35% (95% CI = 1.74-16.74). This brings to our attention the need for extending the surveillance period of this virus in order to adequately assess its teratogenic effects.

title: Syntax Score I and II for Predicting Carotid Artery Stenosis in Patients with Multivessel Coronary Artery Disease: A Propensity Score Matching Analysis

description: Abstract Objective: To evaluate the predictive accuracy of SYNTAX score (SS) I and II for detecting significant carotid artery stenosis (CAS) in patients with multivessel coronary artery disease undergoing coronary artery bypass grafting (CABG) surgery. Methods: The study population consisted of 416 patients. Clinical, demographic, and radiological records were retrospectively reviewed. Characteristics of patients with CAS (n=66) and patients without CAS (n=350) were compared before and after propensity score matching analysis. Results: Patients with significant CAS were older compared to those without significant CAS [(60 (53-65) vs. 63 (59-67); P=0.01]. However, atherosclerotic risk factors and SS I were similar between groups. SS II CABG and percutaneous coronary intervention (PCI) were significantly higher in patients with CAS [37.4 (30.9-43.5) vs. 33.8 (29.9-38.9); P=0.02]. After propensity score matching analysis (66 vs. 66), age, SS II PCI and CABG were significantly higher in patients with CAS than those without CAS [37.4 (30.9-43.5) vs. 33 (29.3-36.9); P=0.03]. Age, SS II PCI and CABG were associated with CAS in logistic regression analysis [OR=1.086, 95% CI (1.032-1.143), P&lt;0.001; OR=1.054, 95% CI (1.010-1.101), P=0.02; OR=1.078, 95% CI (1.029-1.129), P&lt;0.01]. In ROC curve analysis, SS II PCI &gt;33.1 had 68.2% sensitivity and 54.6% specificity [AUC=0.624, P=0.01, 95% CI (0.536-0.707)] whereas SS II CABG &gt;26.1 had 81.8% sensitivity and 54.6% specificity [AUC=0.670, P&lt;0.01, 95% CI (0.583-0.749)] to predict CAS. Pairwise comparison of ROC curves revealed similar statistical accuracy for prediction of CAS (z statistic: 0.683, P=0.49) Conclusion: SS II is useful to predict asymptomatic CAS in patients with multivessel coronary artery disease.

title: Lipid profile and quality of meat from finishing pig supplemented with minerals

description: Abstract This study aimed evaluate the effects of the associated supplementation of: chromium more iron (CrFe), magnesium more selenium (MgSe) and the four minerals (CrFeMgSe) on the parameters related to the pork quality. Supplementation with MgSe reduced the ether extract of the meat and changed the fatty acids profile, increasing the poly-unsaturated, n-3, n-6, the polyunsaturated: saturated rate and the activity of the enzyme Thioesterase index, besides reducing the total number of saturated fatty acids and the Atherogenicity index. It promoted a reduction in a*, b* and C* indices and increased h* of the chilled meat stored. Over the storage days under refrigeration, there was linear drop for L* and a* and an increase to C*. The associated use of magnesium and selenium promotes changes in lipid profile without changing the meat quality, and they may be used in order to obtain meat with more appropriate nutritional aspects.

title: Blueberry pomace, valorization of an industry by-product source of fibre with antioxidant capacity

description: Abstract The industrial by-product of blueberry juice, a source of fibre with antioxidant capacity was used to develop cookies. Once dried and ground the blueberries by-product, its composition and functional properties were analyzed and used to develop fibre enriched cookies. A central composite design was used to optimize the cookie formulation maximizing antioxidant and total polyphenol content varying fibre content (3-9 g/100 g), baking temperature (160-180 °C) and dough thickness (0.5-1.0 cm). Antioxidant capacity and total polyphenol content showed both a similar behaviour, increasing when fibre content increases. The increasing of dough thickness and baking temperature decreases the antioxidant capacity and total polyphenol content. Cookie with 9% fibre, 180 °C baking temperature and 0.50 cm dough thickness and cookie with 9% of fibre, 170°C baking temperature and 0.75 cm dough thickness showed maximum antioxidant capacity and polyphenol content with no significant differences between them; both cookies can be labelled using a fibre claim.

title: THE DEVELOPMENT OF A DIALOGICAL MODEL FOR THE PLANNING OF RESEARCH PROJECTS FOR MIDDLE SCHOOL STUDENTS

description: ABSTRACT Science fairs boost scientific research at school. Since scientific knowledge is privileged in this kind of event, the most prestigious projects are the ones that result from a systematic investigation. In order to enable the planning of investigative projects in a public school of Canoas (RS), this paper aims to propose a dialogical model for the planning of research projects for middle school students. From the academic literacies perspective (LEA; STREET, 1998), the model proposed here seeks to clarify to students what counts as knowledge in a certain area and how it appears in the writing of the project. According to the principles of formative assessment (BLACK; WILIAM, 1998), it was developed a rubrics framework for the elements of a research project. This strategy sees students as protagonists of learning and assessment processes because it allows them to know beforehand how they will be evaluated and what they have to do to achieve the stated goals. In addition, students can also act as concerned readers of each other’s projects, grading them according to the rubrics framework and writing opinions as a form of feedback
