Introduction: Preoperative coagulation screening tests in pediatric patients was once routine clinical practice globally and still used as standard practice in some countries before surgical procedures to assess of perioperative bleeding risk. Objective: The study aimed to evaluate unselected routine preoperative coagulation testing in children undergoing elective or invasive surgery to predict abnormal perioperative bleeding. The study also aimed to provide a rational approach of determining bleeding and family history of coagulation disorders as a predictive risk for bleeding. Methods: This retrospective study conducted between 2014 and 2015 (1 year) on normal healthy children aged under 15 years admitted to the hospitals for elective mild to intermediate surgery or invasive procedures. We reviewed and collected the details of the clinical history, previous surgery, trauma, family history, detail of anti-thrombotic medication and coagulation tests performed (prothrombin time (PT), the activated partial prothrombin time (APTT), and international normalized ratio (INR)) at the time of admission. Results: Among 2078 cases, 1940 cases had normal coagulation tests (93.4%), 77 cases had abnormal coagulation results (3.7%), and 61 patients underwent surgery without preoperative coagulation screening (2.9%). In 15 of 77 patients, coagulation tests were normal on repeat testing. A total of 52 were confirmed to have abnormal screening testing. Among these 52 cases, 45 had normal factors assay; where seven patients had abnormal factors assay. Postoperative bleeding occurred only in three cases (0.14%), two cases due to surgical procedures with normal preoperative testing and one due to hemophilia A which was detected postoperatively as no preoperative testing was performed. Conclusions: Routine coagulation screening before surgery or invasive procedures to predict perioperative bleeding in unselected patients is not recommended. Our study emphasizes that selective preoperative testing is more appropriate. Selective criteria for consideration of the latter includes physical examination, type of surgery, family and bleeding history, and concomitant use of antiplatelet and anti-thrombotic therapy.
Já é alvorada, irmã da manhã: o canto de esperança do sambista

Published: January 2019

Neste artigo, estudamos os termos como aurora e alvorada inscritos em letras de samba,uma vez que entendemos que representam o canto de esperança do cantautor do morro. A fim de analisarmos as letras sob as perspectivas do real e não real, apoiamo-nos nas pesquisas de Coelho (1984), Bachelard (1988; 2008), Chevalier e Gheerbrant (1988), Bloch (2005), Romanelli (2015), Chauí (2016), Mattuella (2016) e Viera (2017). Fazem parte da análise, ainda, os processos de construção do cenário onde habitam os compositores das canções, assim como os de romantização do samba. Lançamos mão, pois, da obra de Vianna (1995), quando traz à tona o mistério do samba; Dantas (1988), que postula as relações entre o estético e o social; Benchimol (1992), por descrever a formação e proliferação dos subúrbios e Galvão (2017), posto que discute a idealização do suburbano. O samba nos possibilita compreender os desejos que cercam o sujeito do morro e de saltarmos junto dele para o que ainda não emergiu, mas que já foi idealizado.

The aim of the study is to compare the sport motives of individuals participating sport in two different groups. 300 volunteers are the participants of the study. Along with the personal information form, Sport Participation Motivation Scale which was developed by Gill et al., (1983) validity and reliability of which was checked for Turkish population by Oyar et al., (2001) and were used. As a result of the analysis, it was found that sport participation motives do not vary according to gender. In addition it was revealed that students of sport high school are more motivated than members of sport centers. Among students of sport high school, certificated sportspeople are more motivated compared to non-certificated sportspeople, individuals doing team and individual sports are more motivated than non-competitive sportspeople and younger students are more motivated than older ones. Among the members of sport center no difference and relation were found between the ages of the sportspeople and their status of owning certificate or not. Furthermore, sport center members doing team and individual sports were seen to be more motivated than non-competitive sportspeople in terms of the dimensions, namely friends, achievement/ status and physical fitness/energy consumption.Extended English summary is in the end of Full Text PDF (TURKISH) file.

The origins of time and human – folklore description
Authors: Kalniuk Tomasz 
Published: January 2019

In traditional Polish folk culture, ordinary villagers were not interested in cosmogenesis and anthropogenesis. However, local folklore provides some interesting examples of narration which revolve around the origins of the world and man. Even at the end of the 20 th century – apart from etiologic tales – Polish scholars recorded some occurrences of so-called “paradise scenes” or “heavens”. These tales or their stagings contained biblical and non-biblical messages concerning the prehistory of man.
Influence of Heating on Tensile Physical-Mechanical Properties of Granite

Published: January 2019

Abstract
Heating procedures dramatically influence the physical-mechanical properties of rock. In this paper, via both numerical simulation and laboratory experiments, we examine the influence of constant temperature period (CTP, from 0.5 to 5 h) and predetermined temperature (PDT, from room temperature to 1,000℃) on the tensile mechanical properties of the Qinling granite, China. Results indicate that: CTP has a significant impact on the tensile mechanical properties of granite. For different PDTs, the density, longitudinal wave velocity (LWV) and tensile strength (TS) of granite decrease with increasing CTP. When CTP reaches the constant temperature turning-point (CTT), heating has fully affected the granite samples. The variation in LWV and TS versus temperature can be divided into four stages: 25–200℃, 200–600℃, 600–800℃ and 800–1,000℃. LWV and TS are negatively related to temperature and are more sensitive to temperature at higher PDTs. In addition, TS is more sensitive to temperature than LWV when PDT increases. The effects of CTP and PDT on LWV are similar to that of TS. Since the measurement of LWV is lossless, researchers can safely determine the appropriate CTP or CTT for any PDT and predict the tensile mechanical properties of rock by LWV analysis.

Glasses of the composition (70–X) mol.% Ga2S3 - 30 mol.% La2S3 - X Er2S3 (at X = 0, 1, 3) were synthesized and the optical absorption spectra at room temperature were studied. Photoluminescence spectra in the 2.53 - 0.73eV range at 300 and 80K were investigated. Intense PL maxima at 2.25, 1.88, 1.45, 1.26, 1.13, 0.81 eV were found which correspond to transitions in the f-shell of erbium ions. The redistribution of the intensity of PL peaks with temperature was analyzed based on the energy transition diagram of erbium ions.

Background: Neuraxial anesthesia-associated maternal hypotension in cesarean delivery is the most frequent and troublesome complication poses serious risks to mother and compromises neonatal well-being. The use of intravenous fluid loading as the preventive strategy in this context has been challenged because inconsistent results cause doubt on its real efficacy. We compared hypotension-preventing effect of crystalloid and colloid with different loading regimens given in a volume-escalation manner in neuraxial anesthetized cesarean parturients.
Methods: One thousand parturients with American Society of Anesthesiologists (ASA) physical status I/II undergoing selective cesarean delivery were screened and 939 were assigned into different fluid loading regimens with a multi-stage randomization. The volume of crystalloid or colloid in each loading regimen was determined by an up-and-down sequential method. Rate of hypotension was recorded as the primary outcome, and the median (EV50) and 90% effective volumes (EV90) of fluids were calculated in epidural and spinal blockades.
Results: A total of 469 subjects were analyzed in the crystalloid group and 470 in the colloid group. The numbers of patients developed clinically significant and severe hypotension are significantly decreased, and the effective volume of colloid required in preventing hypotension in both anesthetized populations is relatively lower than that of crystalloid on the intention-to-treat analyses. There is still an occurrence of hypotension at a rate of about 10%-20% even when the EV90 was reached.
Conclusions: Fluid loading is an effective maneuver in balancing maternal circulation when reaching the effective volume of different neuraxial anesthesia, but prophylactic or therapeutic vasoconstrictors should also be prepared and be given at an appropriate time because a significant proportion of women can still develop hypotension.
Clinical Trial Registration: This trial is registered with ClinicalTrials.gov identifier: NCT01013090.

Background: The nootropic or simply known as smart drug is a common term given to any compound that is responsible for enhancing mental capability or performance. Alzheimer's disease is characterized clinically by lose of cognitive abilities and pathologically by two hallmark lesions, neurofibrillary tangles and senile plaques. It is unfortunate that AD has no cure yet. In this review attempt has been made to elucidate the general views on AD pathogenic hypotheses and common nootropics being used in AD research.
Methods: Articles from credible scientific data bases such as Sciencdirect, Scopus Pubmed, and Google scholar were searched and retrieved using keywords nootropics', Alzheimer's disease', amyloid beta hypotheses', tau hypotheses', cholinergic hypotheses', oxidative stress' and cognitive impairments'.
Results: The nootropics act as Ca-channel blockers, AChE inhibitors, glysine antagonists, antioxidants, serotonergic, dopaminergic and glutamic acid receptors antagonists.
Conclusion: Based on the available literature searched, there is no doubts the nootropics are attenuating cognitive deficits in both preclinical and clinical studies on AD.

Published: January 2019

Coronary heart disease or coronary artery disease is caused by the atherosclerosis process in the coronary blood vessels. The high number of patients with this condition is significantly due to the influence of modern and all instant lifestyle. Among the factors suspected to be capable of influencing the increase in the number of coronary artery lesions in coronary heart patients is the Glomerulus Filtration Rate (GFR). This result is related to the high mortality and morbidity of coronary heart patients. Aim: The purpose of this research is to determine the relationship between the decrease in glomerulus filtration rate (GFR), the disturbance variables (age, gender, hypertension history, diabetes mellitus history, smoking history) and the increase in the number of coronary artery lesions in Sanglah General Hospital. Methods: This research is an analytical observational design with the cross-sectional design using secondary data from the medical records in Sanglah General Hospital Denpasar. This study attains 196 sample. Results: A significant relationship is attained between GFR (<60 ml/ minute) and the increase in the total vessel score (p = 0.017) with an OR 2.47 (CI95% 1.014-6.041). Furthermore, there is a significant relationship between risky age (male >45, female >55) and the increase in total vessel score (p = 0.015) with an OR 3.54 (CI 95% 1.217-10.307). Diabetes mellitus and the increase in the total vessel score also shows a significant relationshipÂ (p = 0.016) with an OR 2.99 (CI 95% 1.189-7.539). While other risk factors such as gender, hypertension, and smoking have an insignificant relationship (p > 0.05). In the multivariate analysis, GFR (<60 ml/ minute) is a predictor of the vessel score (p=0,050) with an adjusted value of OR 1.86 (CI 95% 0.735-4.725). There are some other variables in which are significant predictors of the increase in vessel score. Risky age (male >45, female >55) (p=0,048) with an adjusted OR value of 3.08 (CI 95% 1.012- 9.407) and also diabetes mellitus (p=0.044) with an adjusted OR value of 2.65 (CI 95% 0.145-0.973) are those predictors. Conclusion: Hence, it appears that GFR (<60 ml/ minute), risky age (male >45, female >55) and diabetes mellitus have a significant relationship with the increase in vessel score and are predictors of the increase in vessel score. While gender, hypertension, and smoking do not have significant relationships with the increase in the amount of vessel score.

Background: The antioxidant and anti-inflammatory effects of Cordyceps militaris extracts can neutralize the increased production of Reactive Oxygen Species (ROS) due to hyperglycemia conditions, as well as neutralize NO produced through inducible Nitric Oxide Synthase (iNOS). Thus, the antioxidant effects of C. militaris extract are expected to decrease DNA damage and ER stress leading to intrinsic apoptosis of pancreatic beta cells. Another positive effect of C. militaris which is expected to suppress glucotoxicity is its hypoglycemic effect.Methods: The design of this study was Randomized Post-test Only Control Group Design. The study was conducted on mice divided into three groups: negative control group (DM + placebo), treatment 1 group and treatment 2 group.Results: Based on study on 15 rats, each 5 rats per group, it was found that the mean blood glucose level in control group was 399,20 Â± 28,07 mg/dl, mean of blood glucose level of treatment 1groupÂ (extraction 50% ethanol Cordyceps militaris) was 198.60 Â± 30.42 mg/dl, and, the mean blood glucose levels of the treatment 1 groupÂ (extract ethanol Cordyceps militaris 100%) was 141.00 Â± 17.03 mg/dl. With One Way ANOVA test found that p-value = 0,001. Immunohistochemical examination result shows that beta cell mass is more prominent in either treatment group 1 and treatment group 2 compare to the control group.Conclusions: There were significant differences in blood glucose levels after extracted ethanol Cordyceps militaris. It is further known that ethanol extract of Cordyceps militaris can decrease blood glucose level by 50,25% at 50% concentration and 64,68% at 100% concentration. Immunohistochemical examination result shows that ethanol extract of C. militaris seem could inhibit the decrease of beta cell mass especially at 100% concentration.
Uma leitura do prólogo do Sofista de Platão
Authors: De Aguiar Menezes Neto Nelson 
Published: January 2019

O Sofista é um diálogo dramático. De modo semelhante a outros diálogos platônicos, a obra começa com a cena em ação, em discurso direto, dispensando o papel de um narrador e o uso de terceira pessoa. Provavelmente por conta de seu estilo, os passos iniciais da obra (216a a 218b) são comumente tomados como “prólogo”, sendo entendidos como uma introdução ao diálogo como um todo, cuja investigação filosófica propriamente dita se iniciaria apenas a partir do passo 218b, com a busca pela definição do sofista através do método das dicotomias. Fazendo referência às noções de “prólogo” e de “proêmio”, buscamos conferir aos passos iniciais do Sofista um sentido e uma função para além de uma mera introdução. Neles, não se apresenta apenas o projeto de enquadramento do sofista, como também se pode encontrar, de algum modo já esboçado, a sua própria definição. A proposta deste trabalho é desvencilhar-se de uma leitura en passant dos passos iniciais do Sofista, pretendendo uma interpretação que evidencie o seu caráter ao mesmo tempo literário e filosófico.
Tradução: De gestis Mendi de Saa, de José de Anchieta (I, v. 178-230)

Published: January 2019

A obra De Gestis Mendi de Saa, de autoria do Padre José de Anchieta,editada no ano de 1563 em Coimbra, narra, a exemplo do que o próprio título indica, os feitos de Mem de Sá, terceiro governadorgeral do Brasil. Trata-se de uma obra de teor épico, cuja composição obedece aos parâmetros legados pela tradição clássica, entre os quais se pode referir o hexâmetro dactílico, metro usualmente empregado nas epopeias da Antiguidade clássica. O excerto escolhido para tradução diz respeito à expectativa gerada pela chegada de Mem deSá a terras brasílicas, devido às circunstâncias que envolveram a suaatribulada viagem. O texto ressalta, ainda, as esperanças neledepositadas para solucionar a situação crítica vivenciada na colônia.

Multiplicidade épica num epigrama de Marcial
Authors: Mazzanti Jr. Alex 
Published: January 2019

Em um de seus dísticos, o número CLXXXIV do Livro XIV, Marcial, dialogando com a épica homérica, é capaz de, com enorme poder de síntese, sobrepor múltiplas camadas de significação por meio de uma escolha vocabular precisa e significativa. Buscamos a análise desse breve epigrama, evidenciando essas múltiplas camadas e os sentidos passíveis de serem evocados em tão poucas palavras, que sobrepõem aspectos materiais do livro e aspectos metapoéticos, especialmente os que decorrem do termo multiplex, decalque do epíteto polútropos de Ulisses.
Arete: a virtude em si na Odisseia é uma mulher
Authors: Serra Viegas Alessandra 
Published: January 2019

Este sucinto trabalho pretende trazer uma conversa acerca de uma mulher que Homero nos apresenta entre os cantos VI-XI da Odisseia: a forte e nobre Arete. A rainha dos Feaces e esposa do rei Alcínoo é alguém de quem não se ouve falar muito. No entanto, quando nos aproximamos dessa mulher através da poesia épica, deparamo-nos, na verdade, com a própria virtude em pessoa, a areté como bem o nome lhe representa.Por isso, fica no ar um questionamento: quem é a mulher cheia de virtude na Antiguidade grega? Eis a provocacão -- positiva -- em que este escrito quer envolver o leitor.
Catilina nel teatro di Ben Jonson: un ‘revenant’ cicero-sallustiano
Authors: Tedeschi Antonella 
Published: January 2019

A criação da personagem sombria de Catilina, que domina a peça de Ben Jonson, Catilina, sua conspiração, e resultado de uma leitura atenta pelo autor, que se dedicou a fontes antigas. Na sua reelaboração pessoal da história, Jonson modela fatos e personagens históricos, e os transpõe do codigo narrativo para o teatral. Na sua transposição em palavras e ações daquilo que e narrado pelas fontes, o impacto no público e amplificado: o processo de demonização de Catilina, que começou na Antiquidade com Cícero e Salusto, e completado. A análise de Cíc. Catil. 1, 16 e de Sal. Catil. 22 serve como exemplo: a forma mágico-sacra usada por esses autores antigos atribui um valor negativo ao carisma de Catilina e entrega à posteridade o retrato do genio mau e do subversivo por excelência.
