Introduction The hemogram and hemogram-derivative ratios (HDRs) are becoming markers of the severity and mortality of COVID-19. We evaluated the hemograms and serial weekly HDRs [neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), platelet-lymphocyte ratio (PLR), neutrophil-platelet ratio (NPR) and systemic immune-inflammatory index (SII)] in the survivors and non-survivors of COVID-19. Methods We retrospectively reviewed the medical notes and serial hemograms of real-time reverse-transcription polymerase chain reaction (RT-PCR)-confirmed COVID-19 adults hospitalized from April 2020 to March 2021 from the time of diagnosis to the 3rd week of diagnosis. Results Of the 320 adults, 257 (80.3%) were survivors and had a lower mean age than the non-survivors (57.73 vs. 64.65 years, p < 0.001). At diagnosis, the non-survivors had lower hematocrit (p = 0.021), and lymphocyte (p = 0.002) and basophil (p = 0.049) counts and the hematocrit showed a p-value (Is this what you meant???) of 0.021); higher NLR (p < 0.001), PLR (p = 0.047), NPR (p = 0.022) and SII (p = 0.022). Using general linear models, the survivors and non-survivors showed significant variations with weekly lymphocyte count (p < 0.001), neutrophil count (p = 0.005), NLR (p = 0.009), MLR (p = 0.010) and PLR (p = 0.035). All HDRs remained higher in the non-survivors in the 2nd week and 3rd week of diagnosis and the HDRs were higher in the intubated patients than in the non-intubated patients. The NLR and SII were more efficient predictors of mortality in COVID-19 patients. Conclusions This study shows that serial lymphocyte and neutrophil counts, NLR, PLR, MLR, NPR and SII could serve as good and easily accessible markers of severity and predictors of outcomes in COVID-19 patients and should be used for the monitoring of treatment response. hemogramderivative derivative (HDRs COVID19.

ABSTRACT Phosphorous is a limiting nutrient in sugarcane cultivated in Argisols in the Northeast of Brazil, and understanding its availability in the soil, as well as determining sufficiency ranges in the plants is essential when recommending levels of phosphorus fertiliser. The aim of this study was to: (i) Define classes for interpreting P availability in Argisols of the Northeast using the Mehlich-1 and Anion Exchange Resin (AER) extractors; (ii) Evaluate P extraction by the same extractors; and (iii) Correlate the P content of the soil with the P content of the plants, and establish sufficiency ranges in the plants. Three field trials were carried out in a sandy (PVAd1), medium (PAdx) and clayey (PVAd2) Argisol, applying the following amounts of P: 0, 40, 80, 120, 160 and 200 kg ha-1 P2O5. The AER extracted more P than did Mehlich-1 from each of the soils. The P content of the classes for interpreting P availability determined by the AER were higher than those determined by Mehlich-1. AER was the best extractor to represent P availability in the Argisol with the clayey texture (PVAd2), and Mehlich-1 in the Argisol with the sandy texture (PVAd1). The ranges of P sufficiency in the leaves of the sugarcane varied between soils, with values of 0.66-0.73 g kg-1 in PVAd1, 0.59-0.69 g kg-1 in PVAd2 and 0.34-0.47 g kg-1 in PAdx. As such, the texture of Argisols cultivated with sugarcane in the Northeast of Brazil should be a criterion for choosing the P extractor used in assessing its availability.

Abstract The present article analyzed the process of precarious work relations in the health sector, demonstrating how this situation generated illness and suffering among workers. The text sought to register how the institutional adoption of neoliberal economic conceptions, of the reduction of State social policies, coupled with a history of cultural rejection of labor rights, provided the attraction of mechanisms of precarious work for the public sector, notably, the outsourcing of labor and the provision of services. In a second moment, the text points out the legal improprieties committed, presenting the consequences of the weakening of the legal bond in the working conditions of these workers, mainly regarding working hours and remuneration, also highlighting how much the dissemination of these links represented a factor of a general reduction in wages and labor and social security rights in the sector. Data from Fiocruz surveys on working conditions during the pandemic were also presented. The article concludes by showing the urgency of rescuing the legal labor institutes that were abandoned in the historical path studied in order to guide the public health policies in a new direction.

Resumo O artigo analisou o processo de precarização das relações de trabalho no setor da saúde, demonstrando como essa situação gerou sofrimento dos trabalhadores. O texto buscou registrar como a adoção institucional das concepções econômicas neoliberais, de redução das políticas sociais de Estado, acopladas a um histórico de rejeição cultural aos direitos trabalhistas, proporcionou a atração dos mecanismos de precarização do trabalho, notadamente, a terceirização da mão de obra e da prestação de serviços. No segundo momento, o texto aponta as impropriedades jurídicas cometidas, apresentando as consequências da fragilização do vínculo jurídico nas condições de trabalho desses trabalhadores, principalmente no que se refere às jornadas de trabalho e a remuneração, destacando-se, também, o quanto a disseminação desses vínculos representou um fator de rebaixamento geral dos salários e direitos trabalhistas e previdenciários no setor. Foram apresentados, ainda, dados das pesquisas da Fiocruz sobre condições de trabalho durante a pandemia. Conclui mostrando a urgência de se resgatarem os institutos jurídicos trabalhistas que foram abandonados no percurso histórico estudado, para direcionar a novo rumo as políticas públicas na saúde.

Abstract This study examined how basic psychological needs satisfaction can predict youth participants’ life skills development according to gender and sport type. A sample of 461 Brazilian youth sport participants (325 boys and 136 girls) ranging between 10 and 17 years was included. Data collection was conducted through the Life Skills Scale for Sport and Basic Needs Satisfaction in Sport Scale. Overall, the three subscales of basic psychological needs satisfaction explained a significant amount of the variance in eight life skills (R2 range = .02 to .08 p < .05) and total life skills (R2 = .07; p < .001) in male athletes. Concerning female athletes, multiple regression analyses revealed significant variance only for teamwork (R2=.09; p<.01) and goal setting (R2= .06; p<.05). Regarding the type of sport, the model presented a significant amount of the variance in eight life skills (R2 range = .02 to .05 p < .05) and total life skills (R2 = .08; p < .001) in team sports. Lastly, in individual sports, multiple regression analyses revealed significant variance only on goal setting (R2= .04; p<.05). Findings showed that youth sport coaches could focus on youth participants’ basic psychological needs when trying to foster life skills development across sport contexts. Based on these findings, several suggestions for improving future research and practice in this area are presented.

Abstract Forest ecosystems play an important role in mitigating the concentration increase of carbon dioxide (CO2) in the atmosphere through carbon sequestration by plants and its storage in biomass and soil. The objective was to determine the aerial biomass carbon stock in a dry tropical forest in Brazil. It was developed between 2012 to 2015, in an area with an advanced regeneration stage (50 years) in the semi-arid region of Pernambuco and it was used 40 permanent plots (400 m²) distant 80 m apart, with 50 m from the border, totaling 1.6 ha of the area to sample the shrubby-arboreal component, where all individuals with circumference at breast height (1.30 m of the soil) equal or greater than 6 cm were identified, measured and labeled in 2012 and remeasured in 2015. It was calculated the biomass and carbon stocks through developed equations available in the literature. The results showed that the total biomass and carbon stock in the first year was 27.97 e 12.92 Mg.ha-1 while in 2015 it was 18.49 and 8.39 Mg.ha-1 respectively. The results showed a biomass and carbon stock reduction of more than 30% in the period evaluated, even this, the area manages to present values within the expected pattern for the region, assuring the importance of sustainable forest management of these native/natural vegetation areas.

Resumen La relación entre entrenador y atleta ha sido identificada como un factor determinante para varios resultados positivos en el contexto deportivo. Por lo tanto, los objetivos del estudio fueron analizar la asociación entre la calidad de la relación en trenador-atleta (CAR) y la percepción de la cohesión del equipo de los atletas jóvenes. Participaron 301 atletas, de 15 a 17 años, que compitieron en los Juegos Escolares de Pernambuco, Brasil. Los instrumentos utilizados fueron el Cuestionario de Relación Entrenador-Atleta (CART-Q) y el Cuestionario de Ambiente Grupal (GEQ). El análisis de los datos se realizó a través del modelado de ecuaciones estructurales (p <.05). Los resultados mostraron que la calidad de la CAR mostró una asociación significativa (p <.05) con la cohesión del equipo, explicando el 25% de la varianza de la cohesión de la tarea y el 15% de la cohesión social. Específicamente, el efecto de CAR en la cohesión de tareas (β = 0.50) y social (β = 0.39) fue significativo (p <.05) y positivo. Se concluyó que la calidad de CAR es un factor clave para el compromiso del adolescente con el trabajo en equipo y las metas de este, así como para el desarrollo de relaciones interpersonales positivas.

Abstract The relationship between coach and athlete has been identified as a key factor for several positive outcomes in the sports context. Thus, the aims of this study were to analyze the association between the quality of the coach-athlete relation ship (CAR) and the perception of team cohesion of youth athletes. Participants were 301 athletes, aged 15 to 17 years, who participated in the School Games of Pernambuco, Brazil. The instruments used were the Coach-Athlete Relationship Questionnaire (CART-Q) and the Group Environment Questionnaire (GEQ). Data analysis was conducted through the Structural Equation Modeling (p< .05). The results showed that the quality of CAR showed a significant association (p<.05) with team cohesion, explaining 25% of the variance of task cohesion and 15% of social cohesion. Specifically, the effect of CAR on task (β = 0.50) and social (β = 0.39) cohesion was significant (p<.05) and positive. It was concluded that the quality of CAR is a key factor for the engagement of the adolescent with the teamwork and its goals as well as for the de velopment of positive interpersonal relationships.

Resumen La inteligencia emocional (IE) es una habilidad psicológica que ayuda a los atletas a controlar las emociones y optimizar el rendimiento deportivo. El presente estudio investigó las propiedades psicométricas de la Prueba de Inteligencia Emocional de Autoinforme (SSEIT) en 508 atletas jóvenes y adultos brasileños (edad media 18.55 ± 4.68 años). El análisis de los datos se realizó a través del análisis factorial exploratorio (EFA) y confirmatorio (CFA), alfa de Cronbach, fiabilidad compuesta y correlación de Pearson (p <.05). EFA reveló el modelo de un factor con 26 artículos con el mejor ajuste. CFA confirmó el modelo de un factor con 26 ítems con el mejor ajuste mayor. No se encontró evidencia de invariancia, lo que sugiere que el SSEIT debe usarse con precaución al comparar grupos de genero y edad. La validez externa se encontró en la correlación de la IE y la ansiedad cognitiva y la autoconfianza. Se concluye que la versión brasileña de SSEIT para el contexto deportivo presentó propiedades psicométricas aceptables, sin embargo, mostró limitaciones que deberían explorarse en el futuro.

Abstract Emotional intelligence (EI) is a psychological skill that aids athletes in the control of emotions and optimization of sports performance. The present study investigated the psychometric properties of the Self-Report Emotional Intelligence Test (SSEIT) in 508 Brazilian youth and adult athletes (mean age 18.55±4.68 years). Data analysis was conducted through Exploratory (EFA) and Confirmatory (CFA) Factor Analysis, Cronbach's alpha, composite reliability and Pearson's Correlation (p<0.05). EFA revealed the one-factor model with 26 items with the best adjustment. CFA confirmed the one-factor model with 26 items with best greater fit. No evidence of invariance was found, suggesting that the SSEIT must be used with caution when comparing gender and age groups. The external validity was found in the correlation of EI and cognitive anxiety and self-confidence. It is concluded that the Brazilian version of SSEIT for the sports context presented acceptable psychometric properties, however, showed limitations that should be explored in the future.
