Educação física escolar no ensino médio noturno: um estado da arte / School physical education at night high school: a state of the art / Educación física escolar en la escuela secundaria nocturna: un estado del arte

Objetivo: Analisar as produções acadêmico-científicas a respeito da Educação Física no Ensino Médio, e em especial, no curso noturno. Metodologia: Realizou-se uma pesquisa bibliográfica do tipo estado da arte nos periódicos nacionais da área, com o qualis CAPES da revista, entre A1 e B2, escritos em português, inglês ou espanhol e que tenham em seu escopo o debate com as ciências humanas e saberes pedagógicos. O mapeamento ocorreu entre janeiro e março de 2019. Resultados e discussão: Percebe-se que dos 2.458 artigos publicados nas 05 revistas, apenas 33 estavam relacionadas com a Educação Física no Ensino Médio, correspondendo assim, a 1,34% do total das publicações entre 2011-2018. Identificou-se que o periódico com maior número de publicações no contexto geral da Educação Física pertence à revista Movimento. Isso por si só não legitima o quantitativo de artigos achados sobre a Educação Física no Ensino Médio, ou seja, a revista Pensar a prática possui um número menor de artigos publicados na Educação física no geral, mas um valor numérico, no Ensino Médio, superior comparada a revista Movimento. Conclusão: Nota-se que as principais revistas brasileiras não trazem ou pouco trazem, assuntos relacionados à Educação Física, o Ensino Médio e o Curso Noturno.

Objective: To analyze academic-scientific productions about Physical Education in High School, and especially in the evening course. Methodology: A state-of-the-art bibliographic search was carried out in the national journals in the area, with the CAPES of the magazine, between A1 and B2, written in Portuguese, English or Spanish and whose scope is the debate with the humanities and pedagogical knowledge. The mapping took place between January and March 2019. Results and discussion: Of the 2,458 articles published in the 05 magazines, only 33 were related to Physical Education in High School, thus corresponding to 1.34% of the total publications between 2011-2018. It was identified that the journal with the highest number of publications in the general context of Physical Education belongs to the magazine Movimento. This in itself does not legitimize the number of articles found on Physical Education in High School, that is, the magazine Pensar aprática has a smaller number of articles published in Physical Education in general, but a numerical value in High School, higher compared to the movement Movimento. Conclusion: It is noted that the main Brazilian magazines do not bring or bring little, subjects related to Physical Education, High School and Night Course.

Experiencia clínica con sacubitrilo/valsartán en pacientes con insuficiencia renal: la visión del nefrólogo / Sacubitril/valsartan in chronic kidney disease, the nephrologist point of view

ANTECEDENTES Y OBJETIVO: Sacubitrilo/valsartán ha demostrado ser eficaz en la reducción de la morbimortalidad cardiovascular en los pacientes con disfunción sistólica. El objetivo del presente estudio fue analizar la evolución de pacientes con enfermedad renal crónica (ERC) tras el inicio de sacubitril/valsartán. MATERIAL Y MÉTODOS: Se incluyó a 66 pacientes consecutivos que acudieron a las consultas externas de Nefrología, con ERC y disfunción sistólica. Los criterios de inclusión fueron: presentar una clase funcional II a IV de la New York Heart Association (NYHA) con el tratamiento médico optimizado y ERC estadios 1 a 4. Se recogieron datos basales epidemiológicos y de comorbilidad en el momento de inicio del fármaco. En los meses 1 y 3 se tituló la dosis de sacubitril/valsartán (en función de la tolerabilidad). En cada visita se recogieron datos analíticos de función renal y biomarcadores cardiacos, entre otros. Se analizaron los datos a los 6 meses (fin del seguimiento). RESULTADOS: De los 66 pacientes, 42 eran varones (63%), con una edad media de 73 ± 15 años. La creatinina media fue de 1,42 ± 0,5 mg/dL (filtrado glomerular CKD-EPI 50 ± 19 mL/min/1,73 m2) con una fracción de eyección del ventrículo izquierdo (FEVI) media de 31 ± 9. Al final del seguimiento, la FEVI mejoró significativamente (basal 31 ± 9 vs. final 39 ± 15; p < 0,001). En cuanto a la función renal, el filtrado glomerular por CKD-EPI presentó mejoría al mes (50 ± 19 vs. 53 ± 21 mL/min/1,73 m2; p = 0,005), que se mantuvo estable (filtrado glomerular al final del seguimiento 51 ± 18mL/min/1,73 m2). Abandonaron el tratamiento 7 pacientes (10,6%). CONCLUSIÓN: En nuestra experiencia, sacubitril/valsartán es seguro en los pacientes con insuficiencia renal crónica y estabiliza la función renal a los 6 meses

BACKGROUND AND OBJECTIVES: Sacubitril/valsartan reduces cardiovascular morbidity and mortality in patients with systolic dysfunction. The aim of the present study was to assess the evolution of chronic kidney disease (CKD) patients after initiating sacubitril/valsartan. MATERIAL AND METHODS: We included 66 consecutive CKD patients with systolic dysfunction followed up in outpatient care. Patients had to meet the inclusion criteria of having a New York Heart Association class II to iv, receiving maximum tolerated doses of optimal medical therapy and CKD stages 1 to 4. At baseline, comorbidities and epidemiological data were collected and low doses of sacubitril/valsartan were initiated. At month 1 and 3, doses of sacubitril/valsartan were increased up to the maximum doses if tolerated. In each visit, renal function and cardiac biomarkers were recorded. All the data were analyzed at the end of follow up (6 months). RESULTS: Of the 66 patients, 42 (63%) were men, with a mean age of 73 ± 15 years. Mean creatinine at baseline was 1.42 ± 0.5 mg/dL (glomerular filtration rate estimated by CKD-EPI was 50 ± 19 mL/min/1.73 m2) and mean left ventricular ejection fraction (LVEF) was 31 ± 9%. At the end of follow up, LVEF improved from 31 ± 9% to 39 ± 15% (P < 0.001). After one month of treatment, renal function improved up to 53 ± 21 mL/min/1.73 m2, P = 0.005. For the remaining follow-up time, glomerular filtration rate remained stable (mean at end of follow-up 51±18 mL/min/1.73 m2). Seven patients (10.6%) withdrew from treatment. CONCLUSION: In our experience, sacubitril/valsartan is safe in CKD, offering stability in CKD progression after 6 months

Adelantar la muerte dejando de comer y beber. ¿Un nuevo tipo de "suicidio asistido"? / Hastening death by voluntary stopping of eating and drinking. A new mode of assisted suicide?

En los últimos años ha comenzado a aparecer en la literatura médica y bioética la dicción inglesa "voluntary stopping of eating and drinking". Se trata de una práctica que se propone con la "intención primaria" de anticipar la muerte de una persona que no quiere seguir viviendo, como alternativa a la eutanasia y al suicidio asistido. Algunos autores la presentan como una opción válida tanto desde el punto de vista ético como legal, sosteniendo que no se trata de un suicidio sino de una "muerte natural", en la línea de la limitación de tratamientos. En este artículo presentamos una síntesis de la bibliografía reciente, y una valoración crítica que llega a la conclusión que este tipo de acción difícilmente puede considerarse algo distinto a una modalidad de suicidio. Como consecuencia, el personal sanitario debería considerarla extraña al ethos médico y a la buena praxis clínica

In the last few years, the new catch phrase "voluntary stopping of eating and drinking" has made its appearance in the medical and bioethical literature. The practice, whose "primary intention" is to hasten the death of a person who does not want to continue living, has been proposed as an alternative to euthanasia and assisted suicide. Some authors present it as a valid option from both the ethical and legal point of view arguing that it is basically a "natural death" in the same line as a limitation of treatment and does not involve suicide. In this article we present a critical review of the recent literature and reach the conclusion that it is very difficult to consider this practice as anything other than a type of suicide. In consequence, healthcare workers should consider it alien to medical ethos and good clinical practice

Electrochemical behavior of riboflavin immobilized on different matrices.

The electrochemical behavior of riboflavin (RF) adsorbed on different surfaces of inorganic matrices was investigated using modified carbon paste electrodes. Silica gel and sol-gel silica modified with niobium oxide were denominated as (SN) and (SN(sol-gel)), respectively. These materials were treated with a H3PO4 solution to graft phosphate groups and were denominated as (SNP) and (SNP(sol-gel)). The immobilization of RF on these materials indicated a high electrode stability, avoiding leaching out of the electroactive species (RF) from the electrode surface. The values of formal potential (E0') of the adsorbed RF on the different matrices changed from -283 (SNRF) up to -165 mV (SNPRF(sol-gel)) vs SCE in 0.1 moll(-1) NaNO3 solution at pH 7.0. Compared to the E0' for soluble RF, the values are shifted 183 up to 305 mV toward more positive potentials. The stability of the electrodes and the formal potential of the adsorbed RF on different matrices remained constant upon changing the solution pH from 3 to 8. Some kinetic parameters were estimated; indicating that all systems studied presented a good electron transfer rate.

Electrochemical behavior and electrocatalytic study of the methylene green coated on modified silica gel.

The electrochemical behavior of methylene green (MG) adsorbed on a silica surface modified with niobium oxide (SN) was investigated, using modified carbon paste electrodes. It was also used in an electrocatalytic study of NADH oxidation. The electrode showed a high stability attributed to the presence of SN, which avoids the leaching of the mediator from the electrode surface. The formal potential (E(0')) of the adsorbed MG was -35 mV vs SCE, showing a shift of 30 mV toward more positive potential values, compared to the MG dissolved in aqueous solution. This shift was assigned to the interaction between the basic nitrogen of MG and the acid sites of SN. The variation of the solution pH between 4 and 8 did not affect the stability nor the formal potential. However, for solution pH lower than 4 the formal potential was affected by the acidity of the medium. The electrocatalytic oxidation of NADH at the electrode was investigated. In the solution pH between 5 and 8 the electrocatalytic activity remained almost constant, giving a response signal of 13.3 nA L micromol(-1) cm(-2) and a K(Mapp) of 1.4 x 10(-5) mol L(-1). The electrode gave a linear response range between 5.0 x 10(-4) and 4.0 x 10(-3) mol L(-1) NADH concentration at pH 7.0 at an applied potential of 50 mV vs SCE. Applying a flow injection analysis system, the electrode showed a better analytical performance for NADH detection, presenting a linear response range between 6.0 x 10(-5) and 1.0 x 10(-3) mol L(-1), with an analytical frequency of 30 determinations/h, a detection limit of 8.2 x 10(-6) mol L(-1), and a precision for 25 replicates of 1% expressed as a relative standard deviation.
