ABSTRACT In December 2019, Wuhan, in China, attracted international attention due to a pneumonia outbreak caused by the new coronavirus (2019-nCoV). Infection by 2019-nCoV is more likely in elderly people with comorbidities or with associated chronic diseases. Due to the high transmission rate among humans, this disease is rapidly disseminated, which led to several events being canceled, including the Tokyo 2020 Olympic and Paralympic Games. The aim of this article is to discuss the risk factors for Olympic and Paralympic athletes, as well as for spectators, that justify the decision to postpone the Tokyo Games 2020. Regular physical exercise is associated with health and the prevention of chronic diseases. Although athletes generally appear to be healthy and physically fit, this may not be true. The immune system, which protects the organism from invasive microorganisms, can be affected by the duration and quality of sleep, as well as by physical exercise which influences the quality of the immune response. High volumes of high-intensity physical exercise, as well as changes in sleep patterns during the pre-competition period and the impacts of jet lag on athletes traveling for the Tokyo Games in 2020 may lead to immune system suppression, making these groups more vulnerable to infection by 2019-nCoV. Moreover, during the period planned for the games in 2020 the pandemic may be subsiding in some countries and increasing in others, and this was also taken into consideration as a risk factor. Hence, the decision taken to postpone the Tokyo 2020 Olympic and Paralympic Games until 2021 due to the 2019-nCoV was the correct one, and was extremely important to protect the health of Olympic and Paralympic athletes, as well as spectators.

ABSTRACT Introduction Since its debut at the 1996 Atlanta Olympics, beach volleyball has grown on the international sports scene. An extensive collection of data from several countries and levels of competition will provide a database that can be used to characterize beach volleyball players and define references for training stages. Objective The purpose of this study was to describe and compare the anthropometric profiles of Spanish male and female beach volleyball players at different levels of competition in relation to sports performance. Methods The sample comprised 150 players participating in the 2011 Spanish Beach Volleyball Championships (Under 19, Under 21, and Senior categories). Using the ranking provided by the Royal Spanish Volleyball Federation, the subjects were distributed by performance level (level 1: players ranked first to fourth; level 2: players ranked fifth to ninth; and level 3: players ranked tenth to seventeenth). The study comprised a group of male players, with 18 level 1 ( M1 ), 39 level 2 ( M2 ), and 22 level 3 players ( M3 ), and a group of female players, with 18 level 1 ( F1 ), 41 level 2 ( F2 ), and 12 level 3 players ( F3 ). Results The top level male sample ( M1 ) had a significantly lower average age (19.33 years) than the men’s international elite players (30 years). The top Spanish players of both genders had much lower values for height and body weight than the international elite players. Conclusions Height and fat component are responsible for the differences between top and lower level beach volleyball players, for both men and women. Moreover, as the level of performance increases, players are taller and have a lower fat component. In view of the data observed in this study, the talent selection process in Spanish beach volleyball should aim to select taller individuals than at present.

ABSTRACT Introduction Exercise training using an isokinetic dynamometer is an alternative for improving muscle strength in patients with coronary artery disease (CAD). Few studies have shown metabolic and cardiorespiratory responses to submaximal isokinetic exercises in patients in cardiac rehabilitation programs. Objective To describe cardiorespiratory responses at two intensities of isokinetic exercise. Additionally, we compared the cardiorespiratory responses of isokinetic exercise with data from the incremental cardiopulmonary exercise test (CPET). Methods Eight individuals with CAD (61.7 ± 6.6 years) performed the following tests: 1) CPET on a treadmill; 2) Peak torque test (five repetitions) and fatigue resistance test (20 repetitions) of knee flexion-extension at angular speeds of 120°/s and 180°/s; 3) Two sets of 20 repetitions were performed at 30–40% (low-intensity, LI) and 50–60% (moderate-intensity, MI) of peak torque at angular speeds of 120°/s and 180°/s, using an isokinetic dynamometer. During the exercises, the individuals were connected to an expired gases analyzer with simultaneous monitoring of the electrocardiogram trace, heart rate (HR), oxygen consumption (VO2), carbon dioxide production, and minute ventilation (VE). The differences (∆) between the peak measurements during exercises and the baseline values were calculated. Results Both LI and MI produced cardiorespiratory responses below the anaerobic threshold (82.8 ± 8.1% of HRmax and 74.4 ± 9.6% of VO2peak) compared to the CPET data ( P < 0.01). MI showed higher ∆ HR (9.8 ± 5.5 vs. 6.3 ± 4.6 bpm; P = 0.01), ∆ rate pressure product (3015 ± 2286 vs. 1957 ± 1932 mmHg·bpm; P = 0.01), and ∆VE (10.2 ± 6.2 vs. 6.9 ± 7 L·min-1; P = 0.03) than LI at the angular velocity of 180°/s. Conclusion These results suggest that this isokinetic exercise protocol may be used as a strategy for cardiac rehabilitation programs in patients with CAD. Level of evidence IV; Case series.

ABSTRACT Objective Our study analyses differences in performance between sexes, and changes in performance between age groups at Olympic distance during the ITU Duathlon World Championships, held between 2005 and 2016. During this period, a total of 9,772 duathletes were analysed (6,739 men and 3,033 women). Methods Two-way analyses of variance (ANOVA) were used to examine sex- and age-related differences in performance (time, percentage of time and performance ratio) in the first running and cycling legs, the second running leg, and total race for the top 10 male and female athletes in each age group at the Duathlon World Championships. Results The age group with the highest participation, in both male and female categories, was 40-44 years, and it was found that the mean age of female finisher participants across all age groups was 23.5±12. With regards to performance, the best results for total race time and the cycling segment were achieved in the 30-34-year age group, for both male and female athletes. With regards to performance in the first and third segments (running legs), the best times were achieved in the 25-29 and 30-34 age groups, for men and women respectively. Conclusion According to the results of our study, the best results in the professional career of a duathlete are achieved at between 30 and 35 years, therefore the athlete should incorporate this factor into their training plan.

INFLUENCE OF THE RELATIVE AGE EFFECT ON HEIGHT, MOTOR PERFORMANCE AND TECHNICAL ELEMENTS OF OLYMPIC VOLLEYBALL ATHLETES
Authors: Solon Junior Luiz José Frota , Silva Neto Luiz Vieira da
Published: June 2020

ABSTRACT Introduction The Relative Age Effect (RAE) refers to the chronological age difference that occurs between athletes of the same age category, which can benefit individuals born in the first two quartiles of the year. This phenomenon is commonly studied in team sports, yet the results are still inconsistent, especially in volleyball. Objective This study analyzed the distribution of the number of births per quartile of Olympic volleyball athletes and whether this would influence anthropometric/motor variables and technical elements. Methods The sample consisted of 116 male athletes who scored during the Rio 2016 Olympics. For data analysis, we identified each athlete’s quartile as well as data on height, attack and defensive (or block) range, and respective scores during the games. The Chi-square test was then used to verify interquartile distribution. To assess the normality of the other variables, we conducted the Kolmogorov-Smirnov test. Once accepted, one-way ANOVA was performed with the Bonferroni post-hoc test to verify significance between quartiles. A significance level of p≤0.05 was adopted. Results There was no significant difference in the distribution of athletes between quartiles (p = 0.74). When comparing the other variables in terms of the athletes’ trimester of birth, we did not observe any significant difference between height (p = 0.79), attack (p=0.59) and defensive range (p=0.07), and in the scores for serving, attacking and blocking between quartiles either. Conclusion The Relative Age Effect was not observed in Olympic volleyball athletes, therefore this phenomenon is not related to the athletes’ performance. This shows that other possible variables may influence the development of these athletes, discarding the relative age phenomenon. Level of Evidence III; Retrospective and Comparative Study.

Published: June 2020

ABSTRACT Introduction Small-sided games (SSG) are used as training tools for physical conditioning in soccer. To date, however, it is unknown whether team composition affects athletes’ physical performance. Specifically, based on the differences presented by players of different positions, it is expected that the use of positional status as a criterion for team composition will affect players’ physical performance. Objective To compare the physical demands of SSG in teams composed of young soccer players in the same position or different positions. Methods 12 U-15 soccer players participated in the study. The athletes performed 3v3 SSGs under two conditions: teams in which the athletes played in the same position (i.e. three defenders), and teams in which the players took up different positions (i.e. defender, midfielder and attacker). Data were obtained on total distance traveled, distance in speed zones, and accelerations, using GPS devices. The data were analyzed using the paired t-test, comparing the two experimental conditions. Results There was higher physical demand among defenders and midfielders when the SSG was performed with athletes playing in the same position, in terms of distances covered in different speed zones. However, there were no differences in relation to acceleration actions. Conclusion Team composition affects the physical performance of soccer athletes during 3v3 SSG.

ABSTRACT Introduction Muscle fatigue is characterized by reduced ability to produce maximum strength or power, and may differ between men and women. Changes in velocity of movement during exercise, and in the ability to produce strength after exercise, may help when comparing fatigue in men and women. Objective To analyze the differences between men and women in relation to number of repetitions, kinetics, kinematics and isometric force-time curve performance, and their respective muscle activation in horizontal leg press exercises. Methods Fifteen men and fifteen women underwent isometric force-time curve (Cf-t) and electromyographic (EMG) assessments before and after performing horizontal leg press exercises. The exercises were performed in three sets until voluntary exhaustion, at 70% maximal repetition. During the exercises, kinetic and kinematic variables were obtained by means of two force transducers, a linear position potentiometer and accelerometer adapted for the horizontal leg press and synchronized by a signal conditioning plate. Results The mean propulsive velocity significantly reduced between the first and last repetition of each series, with a similar reduction for men (-12.4 to -29.2%) and women (-29.2 to -35.6%). The same pattern was observed for the other kinetic and kinematic variables. The maximum voluntary contraction and peak force development rate also decreased for both men (-15.1 ± 8.7% and -26.9 ± 21.2%, respectively) and women (-13.9 ± 10.4% and -28.2 ± 11.5%, respectively). Conclusion Based on the different variables used to quantify the effect of fatigue during and after horizontal leg press exercises, the research found practically no differences between men and women.

Published: June 2020

ABSTRACT Introduction Brazilian Jiu Jitsu (BJJ) is an individual sport, characterized by intermittent body movements aimed at the submission (defeat) of the opponent. The sport involves two tactical profiles of fighters: the guard (GG) and the passer (PG), which present potential differences in relation to anthropometric patterns and cardiac autonomic modulation. Objectives To evaluate the effects of different BJJ fighting styles on cardiac autonomic modulation. Methods Twelve PG-style athletes and 12 GG-style athletes, both male, with mean ages of 30.4 ± 1.9 and 30.6 ± 1.3 years, respectively, participated in the study. The following measurements were taken at rest: anthropometric profile, body composition and hemodynamic parameters (blood pressure [BP], basal heart rate [HR] and heart rate variability [HRV], the latter through linear and nonlinear analysis). Results The PG fighters had higher waist and hip circumference diameters compared to the GG fighters (p <0.05). There were no differences regarding baseline hemodynamic parameters of HR and BP. Total HRV as well as parasympathetic modulation indices in both the time and frequency domains were significantly lower in the GG fighters than in the PG fighters (p <0.05). In contrast, the sympathovagal modulation markers in the frequency domain, and the sympathovagal index, were higher in GG than in PG (p <0.05). The SD1 index of nonlinear analysis was lower in the GG fighters than in the PG (p <0.05). Conclusion In general, guardian style fighters have lower vagal modulation and cardiac sympathetic hyperactivity at rest, compared to passing fighters. Level of evidence IV; Case series.

Objective: determine the psychometric properties of the safety practices and behaviors dimension of the Scale of Practices and Behaviors of Institutionalized Elderly People to Prevent Falls in a sample of elderly people with cognitive decline. Method: methodological study, with a quantitative approach, to assess the psychometric properties of the mentioned scale in a sample with 102 elderly people with cognitive decline who lived in two long-term care institutions for the public in this age group. Internal consistency evaluation was carried out by calculating the Cronbach’s alpha coefficient; interobserver reliability was expressed by Cohen’s kappa coefficient; and temporal stability, by obtaining Spearman correlation. Compliance with all ethical procedures was observed. Results: the dimension of safety practices and behaviors showed α = 0.895 for its 11 items. Seven out of the 11 items reached good to excellent agreement among the experts for interobserver reliability. Kappa index values indicated that the instrument is valid and reliable. Safety practices and behaviors were influenced by institutionalization time, being at least 85 years old, and gait skills. Conclusion: the results pointed out that the instrument has good reproducibility and is valid and reliable, which allows its use in clinical practice in elderly people with cognitive decline as well as in research.

Published: June 2020

Objective: to analyze the experience of the patient during hospitalization, focusing on the co-production of care related to patient safety protocols. Method: qualitative study, whose data were collected through the triangulation of multiple sources: document analysis, observation of 10 professionals in the provision of care and 24 interviews with patient-families from 12 clinical and surgical inpatient units of a hospital. Thematic analysis was carried out, based on the concept of co-production. Results: safety protocols according to the experience of the patient portrayed the role of patient-families as co-producers of safe care. It was found an alignment between perceptions of the patients, institutional definitions and basic national and international patient safety protocols. However, these protocols are not always followed by professionals. Conclusion: co-production was perceived in the protocols for safe surgery and prevention of injuries resulting from falls. In patient identification, hand hygiene and medication process, it was found that co-production depends on the proactive behavior of patient-families, as it is not encouraged by professionals. The research contributes with subsidies to leverage the participation of the patient as an agent of their safety, highlighting the co-production of health care as a valuable resource for advancing patient safety.

Published: June 2020

Objective: to verify the relationship between the socio-demographic and work profile of the nursing professionals and the patient safety climate in a public emergency hospital. Method: a cross-sectional study carried out with 177 nursing professionals from a public emergency hospital. For data collection, the Safety Attitudes Questionnaire - Short Form 2006 was used, validated and cross-culturally adapted to the Portuguese language. To check the factors related to the instrument’s domains, bivariate and multivariate analyses were performed. Results: working in the medical and surgical clinic or emergency room, on a night shift, and having the intention to leave nursing, reduced the general safety climate in the multiple regression analysis. The younger professionals, with less than four years in the institution, and those who worked in the night shift had a lower safety climate related to the perception of the management. On the other hand, having a work contract with a hired worker improved the general safety climate and workplace satisfaction. Conclusion: identifying predictors on patient safety scores is an important management tool that allows diagnosing, planning and executing activities from the domains that need to be improved.

Published: June 2020

Objective: to analyze the technological production of three professional master programs in the area of Nursing. Method: documentary research on primary sources. A total of 100 graduate nurses from three professional master’s programs in Nursing in the Southeastern region of Brazil were analyzed, based on the following variables: time of training, typology of products; context of products and technological and educational classification, welfare and management. The study was guided by the question: “How is the technological production of the dissertation of the professional master’s degree according to typology, context and technological classification? The analysis of the data was based on the construction of a table that categorized the products according to the typology. Results: development of techniques was the main type of product found, being expressed by flowcharts, protocols, guidelines and training courses. The products were mostly developed in the hospital context, in the educational technology format. Conclusion: the technological production of the analyzed programs is restricted, diffuse and, in its majority, of low social impact and has no relevance in the body of the dissertation. Despite the wide possibility of conclusion work, the dissertation, accompanied by an article and/or technical productions, is the main form of presentation.

Abstract This work aimed to describe the reproductive biology of Hypoptopoma inexspectatum in southern Pantanal. A total of 538 individuals were sampled and analyzed from February 2009 through January 2011 in southern Pantanal. We did not observe differences in sex-ratio, and both sexes presented positive allometric length/weight relationship (LWR). Reproduction occurs mainly from January to February. Females reached first maturation (L50) with 37.80 mm and males with 45.80 mm. Absolute fecundity is estimated in mean=177.43 (sd±127.06) oocytes and relative fecundity in 3.12 (sd±2.23) oocytes/mg. Fecundity is positively correlated with standard length (Spearman r= 0.43; p=0.013), and total spawning is a used spawning strategy for H. inexspectatum.

Abstract: The development of strategies that conciliate anthropogenic activities with nature conservation is becoming increasingly urgent, particularly in regions facing rapid conversion of native vegetation to agriculture. Conceptual modelling enables assessment of how anthropogenic drivers (e.g. land use/land cover change and climate change) modify natural processes, being a useful tool to support strategic decision-making. The present work describes a conceptual model to evaluate water-related ecosystem service provision under different land use scenarios in the Matopiba region of the Brazilian Cerrado, the world’s most biodiverse savanna and an agricultural frontier. Model variables were determined (direct drivers, indirect drivers, focal components and responses) and the Nature Futures Framework was consulted to incorporate socio-ecological components and feedbacks. Future scenarios were developed considering potential trajectories of drivers and governance responses that may impact land use in the region, including the possibility of full compliance with Forest Code and implementation of the Soy Moratorium in the region. The conceptual model and scenarios developed in the present study may be useful to improve understanding of the complex interactions among anthropogenic drivers, water-related ecosystem services and their potential repercussions for natural and social systems of the region. Governance decisions will be critical to maintaining the ecosystems of the region, the services it provides and the culture and tradition of the people historically embedded in the landscape. In acknowledgment of humanity’s dependence on nature, the importance of inverting the way scenarios are used is highlighted. Rather than using scenarios to measure the impacts of different policy options on nature, scenarios representing the desired outcomes for biodiversity and ecosystem services can be used to inform how policies can guarantee ecosystem integrity into the future.

Resumo Contexto As síndromes de nutcracker e May-Thurner são raras e, apesar de muitas vezes subdiagnosticadas, podem causar sintomas limitantes de gravidade variável. Frequentemente são consideradas diagnóstico de exclusão e não há consenso na literatura quanto a prevalência, incidência e critérios diagnósticos. Objetivos Estimar a frequência da compressão das veias ilíaca comum e renal esquerdas em tomografias computadorizadas de abdome e pelve. Métodos Estudo descritivo, quantitativo e transversal. Para veia renal esquerda, foram considerados como critérios de compressão a relação diâmetro hilar/aortomesentérico > 4 e o ângulo aortomesentérico < 39° e, para veia ilíaca comum esquerda, o diâmetro < 4 mm. Resultados Foram analisadas tomografias computadorizadas de 95 pacientes; destes, 61% eram mulheres e 39% eram homens. A compressão da veia renal esquerda foi encontrada em 24,2% da amostra, com idade média de 48,8 anos, ocorrendo em 27,6% das mulheres e 18,9% dos homens (p = 0,3366). A compressão da veia ilíaca comum esquerda foi detectada em 15,7% da amostra, com idade média de 45,9 anos, ocorrendo em 24,10% das mulheres e 2,7% dos homens (p = 0,0024). Em 7,4% dos pacientes, ambas compressões venosas foram detectadas. Conclusões A compressão da veia renal esquerda ocorreu em mulheres e homens com frequência semelhante, enquanto a compressão da veia ilíaca comum esquerda foi mais frequente em mulheres. Ambas as compressões venosas foram mais frequentemente encontradas em pacientes com idade entre 41 e 50 anos.

Resumo: Neste artigo, o objetivo é analisar como as relações sociais de classe, raça e gênero se articulam na história de Moçambique pós-independência para produzir uma realidade de vulnerabilidade estrutural das mulheres ao vírus da imunodeficiência humana (HIV). A pesquisa bibliográfica adota a teoria social crítica para analisar as políticas governamentais, relatórios de ONGs nacionais e internacionais, pesquisas acadêmicas e outros. No país, as relações de classe, gênero e tradições culturais reafirmam o domínio dos homens sobre a sexualidade, a força de trabalho, a terra e propriedade e a cidadania das mulheres, numa intersecção com o ideário neoliberal, afirmando, não sem resistências das mulheres e suas organizações, o lugar de subalternidade e vulnerabilidade das mulheres em um contexto de epidemia generalizada de HIV/AIDS combinada à pobreza.

Resumo O presente artigo se constrói a partir de reflexões baseadas numa psicanálise brasileira com interface na psicologia social, com o objetivo de dialogar com a Saúde Mental de Moçambique, um país que se subjetiva numa lógica não-ocidentalizada, cujo sistema de cuidado existente há séculos provém do curandeirismo, (re)conhecido no país como Medicina Tradicional. Sendo as políticas públicas de saúde mental regidas a partir de uma visão ocidental, este estudo questionou as reformulações teóricas necessárias para a inserção de novos dispositivos clínicos no país que incluíssem o saber tradicional. Como se trata de uma travessia, optou-se pelo método de escrita de cartas para melhor contemplar o encontro entre estas duas realidades tão diferentes e ao mesmo tempo tão semelhantes.

Published: June 2020

Resumo Para investigar o papel da mobilidade na constituição dos gêneros, realizamos uma pesquisa com mulheres trecheiras - mulheres sem residência fixa, transitando de cidade em cidade e que utilizam os serviços de assistência social. Participaram do estudo duas mulheres usuárias dos serviços da casa de acolhimento aos migrantes de uma cidade do Estado do Mato Grosso do Sul, situada na divisa dos Estados de São Paulo e Paraná. Mediante a perspectiva cartográfica e utilizando entrevistas abertas, observamos trajetórias marcantes de ruptura com a vida sedentária e a passagem para uma vida em trânsito, desprendida de vínculos com a família, o trabalho e os papéis tradicionais atribuídos à mulher. Elas buscaram na errância uma alternativa de vida melhor, uma tentativa de fuga dos problemas e das violências de gênero vividas no ambiente doméstico e no relacionamento familiar e foram aprendendo, dia a dia, no trecho, a viverem como trecheiras.

Published: June 2020

Resumo Objetivou-se compreender a experiência de ouvir vozes a partir das características e conteúdos das vozes, e das estratégias utilizadas por dezesseis ouvidores usuários de um Centro de Atenção Psicossocial do Sul do Brasil. Trata-se de uma pesquisa qualitativa de caráter exploratório. Se deu através de entrevistas semiestruturadas e análise de conteúdo. Evidenciou-se que as características e conteúdos das vozes podem ser determinantes das reações emocionais dos ouvidores frente à experiência, sendo mais difícil lidar com ela quando os conteúdos são negativos. Através das estratégias utilizadas pelos ouvidores, percebeu-se uma resistência ao modelo biomédico, mesmo dentro de um serviço de saúde mental. Conclui-se que há uma necessidade de se pensar outras possibilidades de recuperação para as pessoas que ouvem vozes, que deem conta da complexidade da experiência e que sejam condizentes com o modelo de atenção psicossocial.

Resumo Trata-se de um estudo de caso numa penitenciária do Ceará, Brasil, cujo objetivo foi identificar e analisar percepções ambientais de usuários em ambiente penal, pela expressão de suas experiências no lugar, bem como das simbologias a ele atribuídos. Por meio de entrevistas narrativas realizadas em novembro de 2017, participaram da pesquisa seis presos e seis agentes penitenciários. Suas respostas passaram por análise de conteúdo, permitindo identificar dimensões macro, meso, exo e microsistêmicas de relações ambientais na prisão. Fundamentado na Psicologia Ambiental, concluiu-se que a prisão provoca uma ruptura sócio relacional com o mundo exterior, demonstrando ser incômodo mais relevante do que a sujeição forçada em espaço fisicamente inadequado e superlotado. Ponderou-se, dentre outras reflexões, sobre a função social do aprisionamento que, nas condições atuais, apresenta-se distante dos objetivos de reinserção social e recuperação de pessoas. A prisão provoca sentimentos negativos e depreciadores nas, e sobre, pessoas que o vivenciam.

ABSTRACT Fuzzy logic can simulate wheat yield by nitrogen and temperature nonlinearity, validating the use of hydrogel biopolymer. The objective of this study is to adapt the fuzzy logic model to the simulation of nitrogen biomass and wheat grain yield and non-linearity of the maximum air temperature, under the conditions of use of the hydrogel biopolymer, in high and low N-residual release systems. The study was conducted in 2014 and 2015, in Augusto Pestana, RS, Brazil (28 ° 26 ‘30’ latitude S and 54 ° 0 ‘58’ longitude W). The experimental design was a randomized block design with four replications in 5 x 5 factorial, for hydrogel doses (0, 30, 60, 90 and 120 kg ha-1), added in the furrow next to the seed, and N-fertilizer doses. (0, 30, 60, 90 and 120 kg ha-1), applied at the phenological stage V3 (third expanded leaf) as top-dressing, respectively. The pertinence functions together with the quantitative and linguistic values for the input and output variables are suitable for the use of fuzzy logic in the wheat yield simulation. The fuzzy model made it possible to estimate the values of biomass and wheat grain yield by nitrogen and non-linearity of the maximum air temperature under the conditions of use of the hydrogel biopolymer in high and low N-residual release systems.

ABSTRACT Reduction in plant growth under salt stress is due, among other factors, to changes in photochemical efficiency and, consequently, in photosynthesis. The objective of this study was to evaluate the effect of salt stress on the chlorophyll fluorescence variables in cultivars of basil (Ocimum basilicum L.). The experiment was conducted in a greenhouse, using a randomized block design in a 5 x 3 factorial scheme, corresponding to five basil cultivars (‘Grecco a Palla’, ‘Alfavaca Basilicão’, ‘Alfavaca Verde’, ‘Lemoncino’ and ‘Roxo’) and three salinity of the nutrient solution (2.0, 3.5 and 5.0 dS m-1), with three repetitions, and the experimental plot was represented by three pots containing 3.0 dm3 of coconut fiber. At the full flowering stage, plants were evaluated for chlorophyll fluorescence, when adapted to the dark, as well as under saturating light conditions. In general, there were changes in fluorescence variables only at salinity above 3.5 dS m-1. Fertigation using high-salinity water promotes strong changes in the chlorophyll a fluorescence of sensitive basil cultivars. The cultivars ‘Grecco a Palla’ and ‘Alfavaca Verde’ were little affected by the increase of salinity, being the most tolerant to salt stress. In the cultivars ‘Alfavaca Basilicão’, ‘Lemoncino’ and ‘Roxo’, chlorophyll fluorescence was strongly affected by salinity, being the most sensitive. The tolerance ranking based on chlorophyll fluorescence is: ‘Grecco a Palla’ = ‘Alfavaca Verde’ > ‘Alfavaca Basilicão’ > ‘Lemoncino’ > ‘Roxo’.

ABSTRACT The italian zucchini is a vegetable of national importance, much appreciated, which requires techniques that aim to increase production in less space. Plant spacing can influence the development of plants and the fruit production. The objective of this study was to evaluate the performance of Italian zucchini cultivars as a function of plant spacing. The experimental design was a randomized blocks in a 2 x 4 factorial scheme with four repetitions. The treatments consisted of a combination of two cultivars of zucchini (Alícia and Caserta) and four spacings between plants (0.4, 0.5, 0.6 and 0.7 m). The evaluated characteristics were: total number of fruits plant-1, number of commercial fruits plant-1, total productivity, commercial and non commercial, fresh mass of commercial fruits and dry mass of the plant. The cultivars responded differently to spacings between plants. The Alicia hybrid showed higher commercial yield, 28,490.5 kg ha-1 at spacing of 0.64 m between plants and Caserta cultivar, 26,398.8 kg ha-1 at spacing of 0.4 m.

ABSTRACT Water contaminated with organic carbon and nitrogen compounds is one of the most important water problems in the contemporary world. The main problems related to the discharge of these compounds into natural environments are eutrophication and oxygen depletion. In view of this scenario, the objective of this work was to assess the use of rice husks for the production, growth, and propagation of microorganisms, and the use of these microorganisms for the removal of organic matter and nitrogen compounds in wastewater treatments. The following treatments were evaluated: industrial wastewater (IW), IW + rice husks, IW + sawdust and IW + dried leaves of trees. The effluent was treated with 3% (v v-1) inoculum of microorganisms obtained from rice husks as substrate, applied in a batch system. A solution of 30 mg L-1 of N-NO3 containing 3% (v v-1) of microorganisms obtained from rice husks was used as substrate to evaluate the reusability and performance of N-NO3 removal. Higher microbial growth was found when the rice husks was used as substrate. The chemical oxygen demand, biochemical oxygen demand, total nitrogen, and total solid contents were reduced above 80%. The kinetic evaluation showed that total nitrogen and nitrate can be reduced by up to 80% after 72 h. Moreover, the reuse test showed the stability of the microbial activity after 7 days of use. This study showed that rice husks is an interesting and more sustainable source of carbon for microbial growth, with effective use in wastewater treatments.

ABSTRACT Objective: to reflect on the importance of the participation of nurses in the Clinical Ethics Committee in Brazil and the knowledge required for this performance. Method: reflection based on experience of a postdoctoral internship carried out within the Department of Preventive Medicine, Public Health and History of Science of the School of Medicine of Universidad Complutense de Madrid, Madrid, Spain. Results: the Clinical Ethics Committee contributes to the improvement of health care provided by professionals and health institutions. The nurses are key participants, not only because they are professionals involved in the clinical practice, committed to the decision-making and the patient's performance, but also because they vision is necessary and irreplaceable in an environment of deliberation in which different perspectives and approximations for prudent resolution of ethical conflicts. Conclusion: if the nurses want to assume a strategic position, positively influencing the quality of care provided, protecting interests and ensuring the well-being of the users, they should assume as an urgent basis the need to develop the skills required to deal with ethical problems in the day-to-day of their care practice, accepting the responsibility to participate in the Clinical Ethics Committees, promoting their creation and inserting themselves into their activities.
Edição, política e ditadura: dois livros de oposição da Editora Alfa-Omega
Authors: Maués Flamarion
Published: June 2020

RESUMO Neste artigo, analisarei a edição, pela Editora Alfa-Omega, de São Paulo, de dois livros de oposição: A Ilha (um repórter brasileiro no país de Fidel Castro), de Fernando Morais (1976), e Os exilados: 5 mil brasileiros à espera da anistia, de Cristina Pinheiro Machado (1979). A partir da análise da história da editora, do processo de produção e edição dos livros enfocados e da sua repercussão, buscarei mostrar como e por que eles se caracterizaram como livros de oposição à ditadura então vigente no Brasil e o papel político que estas obras desempenharam no período estudado. Discutirei também a categoria “livros de oposição”, entendendo-a como relacionada a obras literárias que representavam uma manifestação política pública de oposição em um período de forte restrição às liberdades democráticas. Eram, portanto, formas de intervenção possíveis em um quadro ditatorial, que traziam em si as limitações inerentes ao veículo livro, limitações estas relacionadas ao público leitor, à distribuição e ao alcance efetivo dessas obras, e a seu impacto real na conjuntura política do país.

Published: June 2020

RESUMO: Introdução: Os impactos negativos isolados da violência comunitária e da violência familiar na autoavaliação de saúde (AAS) dos indivíduos são conhecidos, mas existe pouca evidência sobre o efeito combinado desses dois tipos de violência interpessoal. Objetivo: Analisar a associação entre a exposição à violência comunitária/por desconhecidos e à violência familiar/por conhecidos e a AAS negativa, distinguindo o tipo de violência sofrido e também considerando sua exposição cumulativa. Métodos: Estudo epidemiológico de corte transversal desenvolvido com os dados da Pesquisa Nacional de Saúde (PNS) 2013. Foram realizados modelos de regressão logística multinominal brutos e ajustados para teste de associação das variáveis. Resultados: Todos os tipos de violência analisados se associaram à AAS negativa. A violência interpessoal comunitária/por desconhecidos isolada esteve associada à AAS como regular (odds ratio - OR=1,38) e ruim (OR = 1,79). A exposição à violência familiar/por conhecidos mostrou-se associada à autoavaliação regular (OR = 1,52) e ruim (OR = 2,70). A exposição concomitante às duas violências mostrou-se associada à avaliação regular (OR = 4,00) e ruim da saúde (OR = 7,81), sendo essa associação de maior magnitude que aquelas para as violências isoladas. Conclusão: O efeito cumulativo da exposição à violência familiar/por conhecido e comunitária/por desconhecido potencializa a avaliação negativa do estado de saúde. Os profissionais de saúde devem estar atentos à polivitimização e ao seu impacto na saúde de vítimas que acessam os serviços de saúde.

ABSTRACT: Introduction: Brazil has registered more than 62,000 confirmed cases of leptospirosis between 2001 and 2017, with more than 2,000 cases confirmed in the State of Pará. Despite a large number of cases, no study has been conducted to trace the spatio-temporal profile of the disease. Methodology: Confirmed cases of leptospirosis from 2001 to 2017 from the state of Pará were the basis for this space-time study. The database of the Department of Informatics of the Ministry of Health was used to access data on leptospirosis. The spatio-temporal analysis was performed in the SaTScan software for the detection of clusters, and maps were generated in the QGIS software. Results: The municipalities of Belém and Santarém were among the ones with the highest incidence rates of leptospirosis for the whole study period. Increased number of cases in Soure, Inhangapi, São João da Ponta and Magalhães Barata, Ponta de Pedras, Breves, Bragança, Castanhal, and São Domingos do Capim were identified in different time periods. Santarém and Belém are the main foci of leptospirosis because they are the most urbanized and densely populated municipalities in the State. The cases found in smaller municipalities may be associated with periods of more frequent rainfall and circulation of Leptospira sp. in marsupials and cattle, in the northeastern part of the State. Conclusion: Further studies are needed to help identify the risk factors that contribute to the occurrence of leptospirosis in the State of Pará, particularly in areas with lower population density.
