ABSTRACT Marajoara Wrestling (MW) is a combat sport that has been not sufficiently investigated. Characterised as a grappling fight, MW demands peculiarities that are still not well known, such as the relationship between physical constitution and the use of competitive techniques. The present study aimed to analyse the technical-tactical performance of the MW in terms of techniques used and combat configuration. This was a cross-sectional observational study from a sample of three male athletes aged between 23 and 33 years. Athletes were filmed in a natural environment during simulated MW combat in order to raise some technical elements of the MW, such as: defensive attitudes, attack technique, takedown and ground fighting. The results allowed the following conclusions: there is no technical-tactical standard in MW, but a combination of elements involving technical-tactical collection, practice time and anthropometric indicators; temporal and functional elements are configured from one’s place of practice; the halter is the most frequent technique, being widely used when combined with other techniques; the defensive work is very similar among athletes, the same does not happen in relation to the ground fight, where differences were observed in the fight configuration. This study is expected to be useful in proposing training programs aimed at the technical-tactical performance of the MW.

RESUMO A Luta Marajoara (LM) é uma modalidade esportiva de combate ainda pouco investigada. Caracterizada como luta de agarre, a LM demanda peculiaridades ainda pouco conhecidas, como a relação entre a constituição física e uso de técnicas competitivas. O estudo tem como objetivo analisar o desempenho técnico-tático da LM em termos de técnicas utilizadas e configuração dos combates. Trata-se de um estudo transversal e observacional realizado a partir de uma amostra constituída por três atletas masculinos com idades entre 23 e 33 anos. Os atletas foram filmados em ambiente natural durante um combate simulado de LM na perspectiva de levantar alguns elementos técnicos da LM, tais como: atitudes defensivas, técnica de ataque, queda e luta de solo. Os resultados permitem as seguintes conclusões: Não existe um padrão técnico-tático em LM e sim uma combinação de elementos envolvendo, acervo técnico-tático, tempo de prática e indicadores antropométricos; Elementos temporais e funcionais são configurados a partir de seu local de prática; A cabeçada é a técnica mais frequente, sendo muito utilizada quando combinada com outras técnicas; O trabalho defensivo é muito similar entre os atletas, o mesmo não acontece em relação à luta de chão, onde se observou diferenças na configuração da luta. Espera-se que o estudo possa ser útil na proposição de programas de treinamento voltados ao desempenho técnico-tático da LM.

Resumen La agresión es un comportamiento que implica una activación simultánea de componentes fisiológicos, bioquímicos, neurológicos, conductuales y emocionales como la ansiedad y la rabia. En los humanos, los deportes pueden considerarse una forma de exhibición porque permiten que la agresión se exprese con una baja probabilidad de daño permanente a los sujetos. Las competiciones se han utilizado como modelos para evaluar la activación producida por las diferentes etapas de la competencia, como el resultado del combate. El judo ha sido utilizado como un modelo de agresión competitiva para evaluar las diferentes respuestas del cuerpo en comportamientos agonísticos en humanos, ya que ofrece un contexto similar a los estudiados en peleas de animales. El objetivo de este estudio fue evaluar el efecto de ganar/perder en los niveles de rabia y ansiedad en luchadores de judo vinculados a la Federación de Judo de Pará, Brasil. Se utilizaron las escalas psicométricas STAXI y STAI, y sus resultados fueron usados en un análisis correlacional para conocer la interacción entre los componentes de las escalas con el número total de golpes, utilizando una evaluación pre/post lucha y la filmación de las peleas. Se encontraron diferencias entre ganadores y perdedores estadísticamente significativas (p< 0.05); los perdedores presentaron mayores niveles de rabia, mientras que la ansiedad fue mayor en los ganadores, debido a que el judo es un medio de competición en el que pueden expresarse de manera socialmente aceptada dichos comportamientos.

Abstract Aggression is a behavior that involves a simultaneous activation of physiological, biochemical, neurological, and behavioral components and emotions, such as anxiety and anger. In humans, sports can be considered as a form of display because they allow aggression to be expressed with a low probability of permanent damage to subjects. The competitions have been used as models to evaluate the activation produced by its different stages, such as the outcome of the combat. Judo has been used as a model of competitive aggression to evaluate the different body responses in agonistic behaviors in humans since it offers a context to those studied in animal fights. The aim of this study was to evaluate the effect of winning/losing in the levels of anger and anxiety in regional male judo fighters, linked to the Pará Federation of Judo, Brazil. The STAXI and STAI psychometric scales and their results were used in a correlation analysis to know the interaction between the components of the scales with the total number of strikes, using a pre/post fight evaluation and the filming of the fights. Significant statistical differences (p <0.05) were found between winners and losers. Losers had higher levels of anger, while anxiety was higher for the winners, being that judo is a mean of competition in which such behaviors can be expressed in a socially accepted way.

O Judô tem sido usado como um modelo de agressão competitiva para avaliar as diferentes respostas do corpo em comportamentos agonísticos em humanos, pois oferece um contexto similar aos estudados em brigas de animais. O objetivo deste estudo foi avaliar o efeito de ganhar/ perder nos níveis de raiva e ansiedade em lutadores de judô já vinculados à Federação de Judô de Pará, Brasil. Se utilizaram as escalas psicométricas STAXI e STAI e seus resultados foram usados em uma análise de correlação para conhecer a interação entre os componentes das escalas com o número total de golpes, utilizando uma avaliação pre/pós briga e a filmagem das lutas. Encontraram-se diferenças entre ganhadores e perdedores estatisticamente significativa (p< 0.05); perdedores apresentaram maiores níveis de raiva, enquanto a ansiedade foi maior para os ganhadores. Sendo que, o judô é um meio competição, onde podem expressar-se de forma socialmente aceitada, ditos comportamentos.

Abstract Conclusion The Unified Health System has undergone constant evolution and expansion since the publication of Brazil’s 1988 Federal Constitution. The Federal District has provided contributions to the field of Primary Health Care Policy, especially between 2016 and 2018, by defining the Family Health Strategy as the definitive way of organizing Primary Health Care (PHC) services and by establishing a set of actions aimed at conversion of existing PHC services to this model. This article describes and analyzes the key processes of this change. The method used was analysis of ordinances, resolutions, reports and other documents, as well as assessment of data from official databases. We emphasize the development of a normative structure that includes the teams’ implementation, the professionals’ work processes, changes in medical specialties and reorganization of the health professionals who already worked in PHC. with an effect of increasing the population’s Family Health Strategy coverage (in a population of approximately 3 million inhabitants) from 28% to 69% during a two-year period, the experience demonstrates the feasibility of incremental changes in health policies such as defining priorities, better management of the workforce, training and decentralized planning to increase access to health services.

Abstract Objectives: This study sought to evaluate the impact of prosthesis-patient mismatch (PPM) on the risk of early-term mortality after transcatheter aortic valve implantation (TAVI). Methods: Databases (Medical Literature Analysis and Retrieval System Online [MEDLINE], Excerpta Medica dataBASE [EMBASE], Cochrane Controlled Trials Register [CENTRAL/CCTR], ClinicalTrials.gov, Scientific Electronic Library Online [SciELO], Latin American and Caribbean Literature on Health Sciences [LILACS], and Google Scholar) were searched for studies published until February 2019. PPM after TAVI was defined as moderate if the indexed effective orifice area (iEOA) was between 0.85 cm2/m2 and 0.65 cm2/m2 and as severe if iEOA ≤ 0.65 cm2/m2. Results: The search yielded 1,092 studies for inclusion. Of these, 18 articles were analyzed, and their data extracted. The total number of patients included who underwent TAVI was 71,106. The incidence of PPM after TAVI was 36.3% (25,846 with PPM and 45,260 without PPM). One-year mortality was not increased in patients with any PPM (odds ratio [OR] 1.021, 95% confidence interval [CI] 0.979-1.065, P=0.338) neither in those with moderate PPM (OR 0.980, 95% CI 0.933-1.029, P=0.423). Severe PPM was separately associated with high risk (OR 1.109, 95% CI 1.041-1.181, P=0.001). Conclusion: The presence of severe PPM after TAVI increased early-term mortality. Although moderate PPM seemed harmless, the findings of this study cannot not rule out the possibility of it being detrimental, since there are other registries that did not address this issue yet.

Abstract Objective: We aimed to analyze whether patent foramen ovale (PFO) closure reduces the risk of stroke, assessing also some safety outcomes after the publication of a new trial. Introduction: The clinical benefit of closing a PFO has been an open question, so it is necessary to review the current state of published medical data in regards to this subject. Methods: MEDLINE, EMBASE, CENTRAL/CCTR, SciELO, LILACS, Google Scholar and reference lists of relevant articles were used to search for randomized controlled trials (RCTs) that reported any of the following outcomes: stroke, death, major bleeding or atrial fibrillation. Six studies fulfilled our eligibility criteria and included 3560 patients (1889 for PFO closure and 1671 for medical therapy. Results: The risk ration (RR) for stroke in the “closure” group compared with the “medical therapy” showed a statistically significant difference between the groups, favouring the “closure” group (RR 0.366; 95%CI 0.171–0.782, P=0.010). There was no statistically significant difference between the groups regarding the safety outcomes, death and major bleeding, but we observed an increase in the risk of atrial fibrillation in the “closure” group (RR 4.131; 95%CI 2.293–7.443, P<0.001). We also observed that the larger the proportion of effective closure, the lower the risk of stroke. Conclusion: This meta-analysis found that stroke rates are lower with percutaneously implanted device closure than with medical therapy alone, being these rates modulated by the rates of hypertension, atrial septal aneurysm and effective closure. The publication of a new trial did not change the scenario in the medical literature.

ABSTRACT Background: Peripheral blood stem cell concentrations are traditionally adjusted to 20–40 × 106 leukocytes/mL prior to freezing. This low cell concentration at cryopreservation implies larger volumes with more dimethyl sulfoxide being used, and higher cost and toxicity at the time of transplant. Higher cell concentrations have been reported but this is not widely accepted. Moreover, the influence of cell concentration on engraftment has not been well documented. Therefore, this study retrospectively analyzed the influence of peripheral blood stem cell concentration at freezing on engraftment after autologous hematopoietic stem cell transplantation. Method: Leukapheresis products were plasma-depleted and cryopreserved with 5% dimethyl sulfoxide, 6% hydroxyethylamide solution and 4% albumin in a −80 °C freezer. Individual patient data from hospital records were reviewed. Results: Fifty consecutive patients with oncological diseases underwent 88 leukaphereses. Median age was six years (range: 1–32 years) and median weight was 19 kg (range: 8–94 kg). Median leukocyte concentration was 109 × 106/mL at collection and 359 × 106 (range: 58–676 × 106) at freezing with 78% viability (range: 53–95%); leukocyte recovery after thawing was 95% (range: 70–100%). In multivariate analysis, cell concentration (p-value = 0.001) had a negative impact on engraftment. Patients infused with bags frozen with <200 × 106 leukocytes/mL engrafted after a median of nine days (range: 8–12 days), 200–400 × 106 leukocytes/mL after 11 days (range: 9–20 days); 400–600 × 106 leukocytes/mL after 12 days (range: 8–19 days) and with cell concentrations >600 × 106 leukocytes/mL, engraftment was after 14 days (range: 13–22 days). Conclusion: In patients with adequate CD34 cell collections, total leukocyte concentrations of 282 × 106/mL, freezing with 5% dimethyl sulfoxide and 6% hydroxyethylamide solution without a controlled-rate freezer, and storing cells at −80 ºC yielded excellent engraftment. Further increases in cell concentration may delay engraftment, without affecting safety.

Considering the complexity of judo and the ample energy and neuromuscular demands, a whole process of competitive preparation must be directed to different physical capacities allowing the athlete to perform his combat actions with the best suitability possible. Mapping the behaviour of a judo athlete from observations of behaviour units in a real fighting situation would be a way of trying to identify the best topography or the best "aptitude" to achieve victory. The present investigation analysed the judo from the interactions of a real competition situation, aiming to verify, between winners and losers, possible differences or correlations between anthropometric parameters, motor performance and functional behaviours in a competitive situation. The results showed that: a) the experience is decisive between winning or losing; b) leg techniques are the most used between winners and losers, and losers use them more frequently; c) there are different strategies between fights; d) The energy cost in judo depends on the configuration of the fights. It is believed that such results can help coaches and athletes in guiding and rationalizing the training process in relation to performance determinants in judo.

Abstract Purpose: To compare the continuous and interrupted suture technique on femoral artery on rats after vessel repair and 14 days after. Methods: Twenty rats were operated randomly divided into two group matched according to the suture technique used: interrupted or continuous. We performed a femoral anastomosis on the right femoral artery. We analyzed weight, arterial caliber, anastomosis time and patency after vessel repair and 14 days after. Results: There was no significant difference between groups in the weight (p=0.64), diameter of the femoral artery (p=0.95) and patency (p=1.00). The time spent in the anastomosis was 451 seconds in the continuous group and 718 seconds in the interrupted group, presenting significant difference (p<0.01). Conclusion: The continuous suture technique shows a similar patency rates than interrupted technique, however with a shorter time to perform the anastomosis.

Resumo Objetivou-se determinar a prevalência e os fatores de riscos de C. tenuicollis em caprinos e ovinos nos matadouros da Paraíba. Foram inspecionados 390 animais (195 caprinos e 195 ovinos) nos municípios de Patos e Esperança, Paraíba, Brasil, no período de Fevereiro a Maio de 2014. A prevalência de C. tenuicollis em caprinos foi de 39% (76/195) e em ovinos de 17,4% (34/195). Os locais mais acometidos por C. tenuicollis nas duas espécies foram o omento e o mesentério. O único fator de risco encontrado foi a produção extensiva de ovinos. Pode-se concluir que é alta a prevalência de C. tenuicollis em pequenos ruminantes no Estado da Paraíba, sendo mais prevalente na espécie caprina; e que ovinos criados de forma extensiva apresentam duas vezes mais riscos de contrais a infecção por este parasita.

Abstract This study aimed to determine the prevalence and risk factors for C. tenuicollis among goats and sheep in slaughterhouses in Paraíba. 390 animals (195 goats and 195 sheep) in the municipalities of Patos and Esperança, Paraíba, Brazil, were inspected between February and May 2014. The prevalence of C. tenuicollis was 39% (76/195) in goats and 17.4% (34/195) in sheep. In both species, most of the cysticerci vesicles were located at the omentum and mesentery. The only risk factor found was extensive sheep farming. It can be concluded that C. tenuicollis is highly prevalent in small ruminants in Paraíba, being more prevalent in goats than in sheep. Extensively-reared sheep were twice as likely to develop infection by this parasite.

Resumo Introdução: A doença renal crônica (DRC) é um grande problema de saúde, determina redução na expectativa de vida e aumento dos riscos de doenças cardiovasculares. Método: Estudo observacional, de coorte, retrospectivo, baseado em dados de prontuários de pacientes com DRC em hemodiálise, diálise peritoneal e transplante renal na cidade de Curitiba, no período de janeiro a junho de 2014, avaliando o impacto financeiro no Sistema Único de Saúde (SUS) e na saúde suplementar. Resultados: O menor custo de um transplante renal no primeiro ano foi de R$ 40.743,03, quando utilizada a ciclosporina, e o maior de R$ 48.388,17, com a utilização do tacrolimo. Já no segundo ano pós-transplante, a hemodiálise e a diálise peritoneal têm valor superior ao transplante renal. Transplante com doador falecido, com tacrolimo: R$ 67.023,39; hemodiálise R$ 71.717,51 e diálise peritoneal automática R$ 69.527,03. Conclusões: Após os dois primeiros anos da terapia renal substitutiva, o transplante demonstra menores custos ao sistema, quando comparado às outras modalidades avaliadas. Baseado nisso, esta terapia justifica melhorias nas políticas governamentais nesse setor.

Abstract Introduction: Chronic kidney disease (CKD) is a major health problem, determining the reduction in life expectancy and an increased risk of cardiovascular disease. Method: An observational, cohort, retrospective, based on patient's medical records data with CKD under hemodialysis, peritoneal dialysis and kidney transplantation in the city of Curitiba, in the period from January to June 2014, evacuativo the financial impact on the Unified Health System (SUS) and the supplementary health. Results: The lowest cost of a kidney transplant in the first year was R$ 40,743.03 when cyclosporine was used and the highest was R$ 48,388.17 with the use of tacrolimus. In the second year post-transplant, hemodialysis and peritoneal dialysis have a higher cost compared to kidney transplant. Transplantation with deceased donor, treated with tacrolimus: R$ 67,023.39; Hemodialysis R$ 71,717.51 and automated peritoneal dialysis automatic R$ 69,527.03. Conclusions: After the first two years of renal replacement therapy, transplantation demonstrates lower costs to the system when compared to other modalities evaluated. Based on that, this therapy justifies improvements in government policies in this sector.

ABSTRACT Introduction: Schistosomiasis is an infectious parasitic disease caused by trematodes of the genus Schistosoma, which threatens at least 258 million people worldwide and its control is dependent on a single drug, praziquantel. The aim of this study was to evaluate the anti-Schistosoma mansoni activity in vitro of novel imidazolidine derivatives. Material and methods: We synthesized two novel imidazolidine derivatives: (LPSF/PTS10) (Z)-1-(2-chloro-6-fluorobenzyl)-4-(4-dimethylaminobenzylidene)-5-thioxoimidazolidin-2-one and (LPSF/PTS23) (Z)-1-(2-chloro-6-fluoro-benzyl)-5-thioxo-4-(2,4,6-trimethoxy-benzylidene)-imidazolidin-2-one. The structures of two compounds were determined by spectroscopic methods. During the biological assays, parameters such as motility, oviposition, mortality and analysis by Scanning Electron Microscopy were performed. Results: LPSF/PTS10 and LPSF/PTS23 were considered to be active in the separation of coupled pairs, mortality and to decrease the motor activity. In addition, LPSF/PTS23 induced ultrastructural alterations in worms, after 24 h of contact, causing extensive erosion over the entire body of the worms. Conclusion: The imidazolidine derivatives containing the trimetoxy and benzylidene halogens showed promising in vitro schistosomicidal activity.

Introduction: The prevention strategy of breast cancer is still the key factor for early diagnosis and the most effective method for tracking the disease. Objective: This study aimed to evaluate the association vitamin D level with breast cancer in women. Methods: This hospital case-control study was conducted with 181 women with breast cancer and 197 healthy controls. Vitamin D status, calcium, phosphorus and PTH serum dosage and data collection related to lifestyle and patient's history, besides anthropometric measurements were performed. Univariate analysis (Chi-square and raw odds ratio) and multivariate analysis were performed through multivariate logistic regression. Results: This study shows a higher value of vitamin D in health controls (26.9 mg/dL) than in breast cancer women (24.8 mg/dL). Higher numbers of women with sufficient vitamin D status (34.85%) were found in control group than cancer group. Using the multiple logistic regression model, the family history of breast cancer (OR 36.37, 95%CI 4.75-278.50) and menopause (OR 5.17, 95% CI 2.72-9.80) had a direct association with breast cancer, while the level of vitamin D (OR 0.95, 95%CI 0.91-0.99) and moderate physical activity (OR 0.31, 95%CI 0.10-0.93) maintained the inverse associations with the disease. Conclusion: Vitamin D status and the practice of moderate physical activity were considered protective factors for breast cancer. However, menopause and family history of breast cancer were considered a risk factor for breast cancer.

Introducción: la estrategia de prevención del cáncer de mama sigue siendo el factor clave para el diagnóstico precoz y el método más eficaz para el seguimiento de la enfermedad. Objetivo: este estudio tuvo como objetivo evaluar el nivel de vitamina D asociado con el cáncer de mama en las mujeres. Métodos: este estudio de casos y controles hospitalarios se llevó a cabo con 181 mujeres con cáncer de mama y 197 controles sanas. Se estudió el nivel de vitamina D, calcio, fósforo y la dosis de suero PTH; se recopilaron de datos relacionados con el estilo de vida y com la historia de las pacientes, además se realizaron mediciones antropométricas. El análisis univariante (Chi-cuadrado probabilidades y primas ratio) y el análisis multivariado se realizó mediante regresión logística multivariante. Resultados: este estudio muestra un valor más alto de vitamina D en los controles de salud (26,9 mg/dl) que en las mujeres con cáncer de mama (24,8 mg/dl). Se encontraron más mujeres con suficiente vitamina D (34,85%) en el grupo control que en el grupo de cáncer. Usando el modelo de regresión logística múltiple, la historia familiar de cáncer de mama (OR 36,37; IC del 95%: 4,75 a 278,50) y la menopausia (OR 5,17; IC del 95%: 2,72 a 9,80) se halló una relación directa con el cáncer de mama, mientras que el nivel de vitamina D (OR 0,95; IC del 95%: 0,91 a 0,99) y la actividad física moderada (OR 0,31; IC del 95%: 0,10 a 0,93) mantienen las asociaciones inversas con la enfermedad. Conclusión: el estado de vitamina D y la práctica de actividad física moderada se consideraron factores de protección para el cáncer de mama. Sin embargo, la menopausia y la historia familiar de cáncer de mama se consideran un factor de riesgo para el cáncer de mama.

Resumo Este artigo versa sobre experiências profissionais ocorridas entre 2005 e 2009 e tem como tema a construção do diagnóstico do Transtorno do Déficit de Atenção/Hiperatividade (TDAH). As práticas exercidas por uma orientadora educacional e psicóloga e por um professor produziram questionamentos derivados de referenciais histórico-críticos os quais constataram que o diagnóstico do TDAH pode estar ocupando o lugar de diversas ausências e conflitos na contemporaneidade, tais como a dificuldade de lidar com a diversidade dos diferentes modos de existência e a de estabelecer interditos e valores morais para nortear a convivência com toda a multiplicidade humana.

Abstract This article delves into the professional experiences occurred during the period from 2005 to 2009; its main subject deals with the construction of diagnosis of Attention Deficit Disorder / Hyperactivity Disorder (ADHD). The practices exercised by a guidance counselor and psychologist, along with a Professor, produced many problematizations. These experiences were all derived from critical historical references which found that the diagnosis of ADHD may be taking the place of several absences and conflicts in contemporary times, such as the difficulty of dealing with the diversity of the different modes of existence, as well as with establishing prohibitions and moral values in order to guide the interaction with all human multiplicity.

ABSTRACTThe aim of this study was to investigate the effect of the bark extractBathysa cuspidata on chemically induced preneoplastic colorectal lesions in Wistar rats. Forty male rats were randomly divided into four groups (n = 10 each): saline (control group, oral administration of saline solution 0.9%); dimethylsulfoxide (DMSO, vehicle control), B200 (treated with 200 mg/kg bark extract ofB. cuspidata), and B400 (treated with 400 mg/kg bark extract ofB. cuspidata). Administration of treatments was carried out by the gavage. The animals received four subcutaneous injections of 1,2-dimethylhydrazine (DMH, 40 mg/kg) in the initial two weeks of the experiment to induce preneoplastic colorectal lesions. After 15 weeks, the animals were euthanized and the presence of aberrant crypt foci (ACF), body weight, biochemical analyses, and oxidative stress markers were measured. The extract ofB. cuspidata decreased the levels of superoxide dismutase (SOD), but did not influence the levels of catalase (CAT), malondialdehyde (MDA), nitric oxide or protein carbonyl, compared with the saline group. The animals supplemented with a more concentratedB. cuspidata extract (B400) showed a significant reduction in the number of ACF in all the portions of the intestinal mucosa. The study demonstrated that the bark extract ofB. cuspidata at 400 mg/kg reduced the preneoplastic colorectal lesions in an animal model of colon cancer and that the effect could be dose-dependent.
