Paediatric reference range for overnight urinary cortisol corrected for creatinine
Authors: Wolthers Ole D. , Lomax Mark , Schmedes Anne Vibeke
Published: May 2021

Objectives

Systemic activity of inhaled corticosteroids (ICS) may be assessed via urinary cortisol measurement. Overnight urinary free cortisol corrected for creatinine (OUFCC) has been extensively reported in adult studies. However, a paediatric mass spectrometric (MS) reference range for OUFCC is not established. MS methods for OUFCC avoid cross-reactivity with other steroid hormones and are thus preferable to immunoassays. The aim of the present study was to define an MS OUFCC normative range in children.

Methods

This was a cross-sectional study of healthy pre-pubertal children from 5 to 11 years. Children collected urine from 10 pm or bedtime, whichever was earlier, until 8 am. Urinary free cortisol was measured via a liquid chromatography tandem mass spectrometry (LC-MS/MS) assay (Acquity UPLC with Xevo TQ-S Mass Spectrometer [Waters]) with in-house reagents. Urinary creatinine was measured using a commercial assay (Roche).

Results

Complete urine collections were obtained from 72 males and 70 females, mean age (SD) 8.6 (1.9) (range 5.0–11.8) years. The OUFCC 95% prediction interval was 1.7–19.8 nmol/mmol. Geometric mean OUFCC was 5.7; range 1.1–24.8 nmol/mmol.

Conclusions

The obtained normative LC-MS/MS OUFCC reference data facilitate the use of mass spectrometry OUFCC assays in assessment of systemic activity of endogenous and exogenous corticosteroids in children.
Looking over the channel: The balance of media coverage about the “refugee crisis” in Germany and the UK
Authors: Maurer Marcus , Haßler Jörg , Kruschinski Simon , Jost Pablo
Published: May 2021

This study compares the balance of newspaper and television news coverage about migration in two countries that were differently affected by the so-called “refugee crisis” in 2015 in terms of the geopolitical involvement and numbers of migrants being admitted. Based on a broad consensus among political elites, Germany left its borders open and received about one million migrants mainly from Syria during 2015. In contrast, the conservative British government was heavily attacked by oppositional parties for closing Britain’s borders and, thus, restricting immigration. These different initial situations led to remarkable differences between the news coverage in both countries. In line with news value theory, German media outlets reported much more on migration than did their British counterparts. In line with indexing theory, German news coverage consonantly reflected the consensual view of German political elites, while British news media reported along their general editorial lines.
The role of D-dimer in periprosthetic joint infection: a systematic review and meta-analysis
Authors: Balato Giovanni , De Franco Cristiano , Balboni Fiamma , De Matteo Vincenzo , Ascione Tiziana , Baldini Andrea , Lippi Giuseppe
Published: May 2021

Objectives

The current literature on diagnosis of periprosthetic joint infection (PJI) provides controversial evidence on the diagnostic accuracy of D-dimer. Therefore, this critical literature search and meta-analysis was aimed to summarize the diagnostic accuracy of D-dimer for diagnosing PJI.

Content

We searched MEDLINE, Scopus, and Web of Science, for studies on D-dimer for diagnosing PJI, according to the PRISMA flowchart. QUADAS was used for assessing study quality. Sensitivity, specificity, positive (PLR) and negative likelihood ratio (NLR), and diagnostic odds ratio (DOR) were analyzed using bivariate diagnostic random-effects model. The area under the receiver-operating curve (AUC-ROC) was calculated. Subgroup analysis and univariate meta-regression were carried out for detecting potential sources of heterogeneity.

We included 12 articles, totaling 1,818 patients (539 with PJI). The pooled sensitivity and specificity of D-dimer for diagnosing PJI were 0.739 (95% CI: 0.616–0.833) and 0.785 (95% CI: 0.679–0.863). The pooled PLR, NLR, DOR were 3.359 (95% CI, 2.340–4.821), 0.295 (95% CI, 0.180–0.484), and 11.787 (95% CI, 5.785–24.018). The cumulative ROC plot displayed an AUC of 0.688 (95% CI, 0.663–0.713; p<0.001). No threshold effects could be observed. The type of blood sample was identified as possible source of heterogeneity for DOR (p=0.01).

Outlook

Evidence emerged from this meta-analysis suggests that D-dimer displays sufficient diagnostic accuracy to rule out PJI. The type of blood sample (plasma vs. serum) and the study design could influence the results in terms of DOR and sensitivity. However, further perspective studies would be needed to validate its potential diagnostic usefulness.
High-efficiency three-way Doherty power amplifier using reconfigurable PD
Authors: Zhao Shiwei , Guan Jun , Zhou Xiaoqi , Xu Yuehang
Published: May 2021

In this paper, a new reconfigurable power divider (PD) is proposed to improve the efficiency of the three-way Doherty power amplifier (DPA). The conventional λ/4 transmission line is replaced by the proposed reconfigurable PD in the input of peaking amplifier, where the 90° phase shift and impedance matching can be achieved. Furthermore, the output power distribution ratio (PDR) can be continuously adjusted in a large range by adjusting the reverse voltage of the varactor diodes. Therefore, the reconfigurable PD with the best PDR can assign input power to the peaking amplifier. Experiment results show that the maximum measured power added efficiency (PAE) of the proposed three-way DPA is 49%, which is improved by 5% compared with conventional three-way DPA.
Ecological risk assessment of toxic metal pollution in the industrial zone on the northern slope of the East Tianshan Mountains in Xinjiang, NW China
Authors: Abliz Abdugheni , Abliz Abdulla , Shi Qingdong
Published: May 2021

The ecological risks of six toxic metals (Zn, Cu, Cr, Pb, Hg, and As) in the industrial zone on the northern slope of the East Tianshan Mountains in Xinjiang, northwest (NW) China, were assessed. The results showed that the soil toxic metal contents of Zn, Pb, Hg, and As exceeded the regional background values, and concentrations of Zn, Cu, Pb, and As exceeded the national soil environmental quality standards of China (GB15618-1995). The Cu and Cr contamination levels were lower than the limits of both soil standards and mainly originated from the parent material, Pb mainly originated from agricultural activity and traffic emissions, and Hg mainly originated from the coal burning and chemical industries. As contamination originated from automobile exhaust emissions, and Zn contamination was influenced by a combination of natural factors and human activities. The mean geo-accumulation index (I
geo) values of As, Hg, and Pb ranged from unpolluted to moderately polluted. There was an area not polluted by Zn, Cu, and Cr. The pollution index (PI) value of the six heavy metals showed that the mean PI values of Zn, Cr, and Cu showed no pollution, As and Pb presented medium pollution, and Hg presented heavy pollution. The results of the potential ecological risk analysis in this region showed that Zn, Cu, Cr, and Pb in all sample sites presented a low risk, while Hg presented a high ecological risk. Therefore, it is necessary to prevent further Hg contamination in this region.

Una vez identificados los rasgos comunes de las versiones orientales, se siguen sus huellas por los apólogos ibéricos de la Edad Media. El resultado de este análisis revelará que existen determinados vínculos entre las tradiciones norteafricana y medioriental de El medio amigo y las versiones incluidas en los Castigos de Sancho IV (mss. B y C) y en el Libro del cavallero Zifar.
Una aproximación al contexto socioliterario de José Joaquín Benegasi y Luján
Authors: Padilla Aguilera Tania
Published: May 2021

José Joaquín Benegasi y Luján (1707–1770) es un escritor que, aunque considerado menor por la crítica dieciochista tradicional, tiene un singular perfil autorial que preconiza algunos rasgos del autor moderno. Así, en su producción poética se aprecian características que adelantan el definitivo cambio de mentalidad que se produce a partir del siglo XIX en relación con la construcción de la moderna imagen autorial. Además, la específica red de sociabilidad madrileña de la que formaba parte, así como el sello personal de sus textos, permiten adelantar algunas conclusiones.
Los maestros científicos: autores de artes de escribir y contar en el Siglo de Oro español
Authors: Gómez Camacho Alejandro
Published: May 2021

Los maestros laicos con escuela pública constituyeron una minoría en la escena pedagógica y lingüística española de los siglos XVI y XVII. Este estudio propone la consideración de los manuales de escritura y aritmética, publicados exclusivamente por maestros con escuela pública distanciados por diversos motivos de la corte española, como un género alternativo y minoritario. La transdisciplinariedad de estas obras y la singularidad de sus autores se representan en el término “maestro científico”, que fue acuñado en una de estas artes. Estos autores y sus obras anticipan a los maestros ilustrados y ofrecen una visión diferente e inexplorada de la alfabetización en el Siglo de Oro español.
El primer milagro económico alemán visto por los viajeros españoles (1834–1936)
Authors: Perdices de Blas Luis , Ramos Gorostiza José Luis
Published: May 2021

Antes de 1871 los pocos viajeros españoles que visitaron los estados alemanes lo hicieron de forma fugaz y muy parcial, caracterizándolos como pintorescos territorios de leyendas románticas y bellezas naturales. Entre 1871 y 1918, en la búsqueda de referentes para la modernización de España, creció la fascinación por la espectacular transformación económica alemana: se fue afianzando entre los viajeros españoles la imagen de gran potencia industrial que lideraba el conocimiento y los avances técnicos, solo empañada por la percepción de un notable militarismo y un cierto culto al maquinismo. Esta sólida imagen de Alemania persistiría entre los españoles pese a las grandes dificultades económicas de entreguerras.
La Academia Chilena de la Lengua y la reforma ortográfica del castellano en Chile (1913–1927)
Authors: Cáceres Valentina , Rojas Darío
Published: May 2021

Estudiamos el papel de la Academia Chilena de la Lengua en la reforma ortográfica en Chile entre 1913 y 1927. A partir del análisis de sus intervenciones glotopolíticas y las ideologías lingüísticas manifestadas en una serie de discursos, identificamos dos proyectos antagónicos de política lingüística, aunque paradójicamente coincidentes en cuanto a presupuestos lingüístico-ideológicos: la oficialización de la ortografía de la RAE y la conservación de la ortografía reformada chilena, vigente desde 1844. La primera de estas fue la postura institucional de la Academia. Mediante sus intervenciones en las esferas académica, política y periodística, concentradas en 1913–1914 y 1918, la Academia consigue que en 1927 el Estado chileno oficialice la ortografía de la RAE. Con ello logra satisfacer su misión de agente local del hispanismo y al mismo tiempo contribuye a preservar la posición privilegiada de las élites hispanohablantes chilenas en el contexto local.
Information Inequality among Entrepreneurs in Rural China
Authors: Fan Zhenjia , Fichman Pnina
Published: May 2021

As rural entrepreneurs in China are disadvantaged, compared to other entrepreneurs, the local and central governments provide a host of incentives to promote their success. Rural entrepreneurs are information poor and it is possible that their information behaviors differ from others, causing them to lag behind. The study aims to develop a framework of information inequality among rural entrepreneurs in China, based on the information capability approach. Grounded in thematic content analysis of 44 interviews with these entrepreneurs about their information behaviors, the study proposes a comprehensive framework for understanding information inequality among rural Chinese entrepreneurs. The framework includes two components: 1) eight major information functionings, where information inequality occurs; and 2) three factors that affect information functioning. By focusing on information functionings, and specifically effective information use, the framework allows for a more nuanced understanding of information inequality. Findings suggest that ICTs adoption is not the decisive factor in information functionings, and instead finds blurred boundaries between online and offline information functionings. As such, the study proposes to avoid technological determinism in understanding the impact of ICTs on information inequality, and instead uses social informatics lenses to account for both online and offline information functionings in this context.

The optoelectronic properties of semiconductor nanoparticles make them valuable candidates for the long-term monitoring of transmembrane electric fields in excitable cells. In this work, we show that the electric field sensitivity of the fluorescence intensity of type-I and quasi-type-II quantum dots and quantum rods is enhanced under two-photon excitation compared to single-photon excitation. Based on the superior electric field sensitivity of the two-photon excited fluorescence, we demonstrate the ability of quantum dots and rods to track fast switching E-fields. These findings indicate the potential of semiconductor nanoparticles as cellular voltage probes in multiphoton imaging.
Inferior Occipital Gyrus Is Organized along Common Gradients of Spatial and Face-Part Selectivity
Authors: de Haas Benjamin , Sereno Martin I. , Schwarzkopf D. Samuel
Published: May 2021

The ventral visual stream of the human brain is subdivided into patches with categorical stimulus preferences, like faces or scenes. However, the functional organization within these areas is less clear. Here, we used functional magnetic resonance imaging and vertex-wise tuning models to independently probe spatial and face-part preferences in the inferior occipital gyrus (IOG) of healthy adult males and females. The majority of responses were well explained by Gaussian population tuning curves for both retinotopic location and the preferred relative position within a face. Parameter maps revealed a common gradient of spatial and face-part selectivity, with the width of tuning curves drastically increasing from posterior to anterior IOG. Tuning peaks clustered more idiosyncratically but were also correlated across maps of visual and face space. Preferences for the upper visual field went along with significantly increased coverage of the upper half of the face, matching recently discovered biases in human perception. Our findings reveal a broad range of neural face-part selectivity in IOG, ranging from narrow to “holistic.” IOG is functionally organized along this gradient, which in turn is correlated with retinotopy.

SIGNIFICANCE STATEMENTBrain imaging has revealed a lot about the large-scale organization of the human brain and visual system. For example, occipital cortex contains map-like representations of the visual field, while neurons in ventral areas cluster into patches with categorical preferences, like faces or scenes. Much less is known about the functional organization within these areas. Here, we focused on a well established face-preferring area—the inferior occipital gyrus (IOG). A novel neuroimaging paradigm allowed us to map the retinotopic and face-part tuning of many recording sites in IOG independently. We found a steep posterior–anterior gradient of decreasing face-part selectivity, which correlated with retinotopy. This suggests the functional role of ventral areas is not uniform and may follow retinotopic “protomaps.”
High biodegradability of riverine dissolved organic carbon in late winter in Hudson Bay, Canada

Published: May 2021

Hudson Bay, at the southern margin of the Arctic Ocean, receives nearly one-third of Canada’s river discharge and approximately 5.5 Tg of riverine dissolved organic carbon (DOC) annually. Riverine DOC fluxes to Hudson Bay are expected to increase with climate change, but how this increase will influence the biogeochemistry of the coastal waters is largely unknown. In particular, the fate of riverine DOC that enters Hudson Bay during the dark, frozen winter period (roughly January to April) is poorly known despite high discharge from the large, regulated rivers of Hudson and James Bays at that time. Few studies have assessed the degradability of riverine DOC transported in winter anywhere across the Arctic, leaving unanswered questions regarding the impact of riverine DOC on the Arctic carbon budget, CO2 fluxes, and local food webs. Here, we assessed the biodegradability of DOC in riverine and coastal waters of southern Hudson Bay in late winter using 45-day incubation experiments. We found 24%–60% of the DOC in the rivers and on average 21% of the DOC in the immediate coastal waters to be biodegradable. Differences in biodegradability appeared to depend on properties of the rivers/watersheds and physical and biochemical processes in the aquatic environments. DOC biodegradability correlated strongly with DOC concentration, which was higher during winter than summer in all studied rivers and higher in the Nelson and Hayes Rivers, draining the Hudson Bay Lowlands than in most previously studied large rivers of the Arctic watershed. The Nelson River, regulated for hydropower production, had the highest winter DOC concentrations and most degradable DOC. The high biodegradability of Hudson Bay riverine DOC in late winter and high concentrations and fluxes of riverine DOC at that time imply strong leverage for future increases in DOC fluxes to impact the carbon cycle of these coastal waters.

Published: May 2021

This study aimed to predict the binding affinity, orientation, and physical interaction between limonene and fat mass and obesity-associated protein. The mechanism of limonene and protein association was explored by molecular docking, a bioinformatic tool. The results of association were compared with the reported results of the anti-obesity drug such as orlistat and with the flavonoids. AutoDock Vina tools were used for the molecular docking of limonene with fat mass and obesity-associated protein. PyMol and Discovery Studio Visualizer were used to visualize the results of this docking. The binding affinity of limonene was higher (Least negative G) than the orlistat and flavonoids such as Daidzein, Exemestane, Kaempherol, Letrozole, And Rutin. It is conducted in this study that the Limonene can alleviate obesity by making an interaction with the fat mass and obesity-associated protein. This inhibitory interaction was greater as compared to other reported phytochemicals and drugs.
Influence of knife geometry on selected factors pertaining to the delimbing process
Authors: Melicherčík Ján , Krilek Jozef , Kováč Ján , Harvánek Pavol
Published: May 2021

Cutting mechanisms and the cutting force are the focus of this article. The cutting force can be determined theoretically or mathematically by statistical analysis. In this work, the cutting speed was compared when changing the diameter of the test wood and when using the three types of angular geometry of delimbing knives. Experimental measurements were conducted on a self-designed experimental pneumatic stand. Empirical relationships and values from the scientific literature were used to determine the input parameters. Based on a regression analysis, conclusions were drawn relative to factors affecting the process of delimbing. The angular geometry of the delimbing knife plays a significant role in the delimbing process. The thicker the knife, the higher the energy consumption in the cutting process and the poorer the quality of the cutting surface of the wood. The quality of chipless separation timber was found to depend on the cutting speed, and the optimal speed was 2.0 m s-1.
Effect of ozone treatment on softwood soda lignin-based water reducer performance for concrete
Authors: Takahashi Shiho , Uraki Yasumitsu , Yamada Tatsuhiko
Published: May 2021

A lignin-based water reducer for concrete was prepared from softwood soda lignin. The soda lignin and the lignin-polyethylene glycol (PEG) derivative were modified with ozone to improve their performance as water reducers. The performance of ozone-treated soda lignin was superior than untreated soda lignin and commercial lignosulfonate-type water reducers in the mortar flow test. The soda lignin treated with a high ozone charge showed better performance than lignin treated with a low ozone charge. The ozone treatment improved the performance of the lignin-PEG derivative water reducer as well. The lignin-PEG derivative water reducer with a longer PEG chain length showed better performance than that of the shorter PEG chain. The zeta potential of cement suspension with the ozone-treated soda lignin showed a higher negative value than the untreated soda lignin. The data of zeta potential analysis suggested that the electrostatic repulsion force of cement particles with the ozone-treated lignin would be larger than the untreated lignin.
The Quality of Relationship with Stakeholders, Performance Risk and Competitive Advantage in the Hotel, Restaurant and Café Market

Published: May 2021

While emerging markets have become an opportunity for companies in the less populated and saturated markets to expand their business, they also impose challenges for foreign partners’ competitive behavior. To offer the value that would be competitive in emerging markets, companies need to improve the quality of their relationship with business partners. Relationship quality may enhance the probability of continued interchange between companies and their stakeholders, leading to increased attractiveness for the emerging markets’ economy. This research explores antecedents (communication and relationship longevity) of relationship quality with stakeholders (suppliers, customers, and employees) and how the relationship quality with three stakeholders impacts the company’s performance risk and competitive advantage in the Lithuanian hotel, restaurant, and café market. The findings suggest that communication and relationship longevity have a positive effect on relationship quality with all three stakeholders. A higher level of relationship quality with stakeholders has a more positive effect on competitive advantage and a more significant negative effect on performance risk. The study expands the understanding of relationship quality antecedents (communication and relationship longevity) and relationship quality with customers, suppliers, and employees in terms of competitive advantage and performance risk in the less populated and saturated hotel, restaurant, and café market seeking expansion to emerging markets.
CHILE: CINCUENTA AÑOS DESPUÉS... NUEVAMENTE LAS GRANDES ALAMEDAS

La opción entre la justicia y la libertad fue el gran dilema del sigloveinte. Se manifestó en confrontaciones dentro de cada estado-nación y en el enfrentamiento entre países socialistas que enarbolaron la bandera de la justicia y los capitalistas que enarbolaron la de la libertad.Hay que admitir que los cambios necesarios en pro de la justicia social provocan irremediablemente restricciones a la libertad por el simple hecho de que, para lograr justicia, es necesario disputar riqueza y poder a quienes los detentan y disfrutan, pues la libertad irrestricta,sobre todo en los procesos económicos, produce excesos de acumulación en manos de unos y explotación de grandes sectores mayoritarios. En consecuencia, un paso adelante en la justicia social significa un paso atrás en el proceso de acumulación y eso desata la respuesta de sus beneficiarios tanto más violenta cuanto más se avanza en el logro de la justicia.

Published: May 2021

O objetivo deste artigo é verificar o impacto do Programa de Apoio a Planos de Reestruturação e Expansão das Universidades Federais (Reuni) na Universidade Federal de São Carlos (UFSCar) a partir de estudo comparativo de seus dois Planos de Desenvolvimento Institucional (PDI) – 2004 e 2013. Este estudo tem base em análise bibliográfica e documental e configura-se a partir das seguintes categorias de análise: Ampliação da Oferta de Educação Superior Pública; Reestruturação Acadêmico-Curricular; Renovação Pedagógica da Educação Superior; Mobilidade Intra e Interinstitucional; Compromisso Social da Instituição; Suporte da Pós- Graduação ao Desenvolvimento e Aperfeiçoamento Qualitativo dos Cursos de Graduação. Constatou-se que a adesão da UFSCar ao Reuni, em 2007, pode ser entendida como uma ação política de conveniência da gestão da Universidade para recebimento de verbas para consolidação de suas ações, metas e mecanismos de regulação já previstos no seu primeiro PDI 2004. Apesar da conveniência da adesão, pode-se concluir que o referido Programa acabou atuando de forma profunda na Instituição ao exercer forte impacto em seu PDI 2013, gerando novas demandas e ênfases, bem como o aprofundamento de algumas delas, agindo no sentido de intensificar ações e políticas reguladoras da UFSCar com vistas ao cumprimento do Contrato de Adesão firmado com o MEC em um contexto de precariedade orçamentária.

O objetivo do estudo foi o de compreender a atuação profissional dos Técnicos em Assuntos Educacionais na formação inicial dos alunos do curso de Educação Física da Universidade Federal de São Paulo sob a ótica docente. Para tanto, foi desenvolvida uma pesquisa descritiva que contou a participação de dez docentes do curso de Educação Física da instituição. A entrevista semiestruturada foi utilizada como instrumento de coleta de dados e a análise das respostas foi feita por categorias não apriorísticas. Os resultados apontaram que os professores compreendem de forma distinta a atribuição dos Técnicos em Assuntos Educacionais refletindo a abrangência da legislação sobre o cargo. Em nosso entendimento, ainda há uma falta de clareza na natureza da atribuição dos Técnicos em Assuntos Educacionais.
O teletrabalho como política pública de inclusão social das pessoas com deficiência no Brasil
Authors: Da Silva Wellington Rodrigo Lozano , Gilio Leandro
Published: May 2021

Este estudo tem como objetivo avaliar as possibilidades do teletrabalho, lançando foco sobre a regulamentação legal dessa modalidade de trabalho, em especial no que se refere à nova redação do Art. 6º da Consolidação das Leis do Trabalho (CLT) e às inovações trazidas pela reforma trabalhista aprovada em 2017. Também se propõe uma reflexão sobre políticas públicas de emprego no Brasil e de inclusão social, mais especialmente no que tange às possibilidades para pessoas com deficiência ou dificuldades de mobilidade, que poderiam ser beneficiadas com a promoção do teletrabalho. Avalia-se que o teletrabalho pode abrir oportunidades e postos de trabalho para pessoas com deficiência e dificuldades de mobilidade, porém o tema ainda requer maior atenção no que se refere à pesquisa científica e políticas públicas voltadas à temática.
A proteção à saúde e a segurança do trabalhador no ARE 664.335: uma análise sob a ótica da dignidade da pessoa humana

A aposentaria especial encontra-se entre o rol dos direitos mais relevantes e indispensáveis a realização da dignidade do indivíduo enquanto pessoa humana. Isto porquê, tem como objetivo máximo a proteção à saúde e a segurança do trabalhador, de modo a afastá-lo o quanto antes de condições nocivas de trabalho. Porém, conforme será exposto no decorrer do presente ensaio, recentemente nos deparamos com um patente retrocesso social oriundo do ARE 664.335 que, em tese de repercussão geral acabou por fixar interpretação restritiva ao alcance de um direito de tamanha essencialidade partindo de fundamentos altamente questionáveis, o que impõe a realização de uma análise crítica da decisão. Para tanto, a pesquisa em epígrafe utilizará uma técnica de metodologia baseada no levantamento bibliográfico e no estudo do material doutrinário.
A relevância dos tribunais de contas no auxílio do controle externo frente à ineficiência da administração pública
Authors: Maia Guilherme Aparecido da Silva , Teles Diego Schlosser de Sá
Published: May 2021

Este trabalho aborda assuntos atuais e relevantes acerca dos Tribunais de Contas e de sua indispensável participação nas atividades de controle externo. O enfoque está voltado às precariedades de toda a sistemática política e administrativa em que estão inseridas as Cortes de Contas, bem como na importância da autonomia e independência desses Tribunais. A metodologia utilizada é preponderantemente a pesquisa bibliográfica, sem deixar de lado, todavia, a pesquisa em sítios eletrônicos que apresentam temas atuais e de relevante interesse público. O objetivo maior deste trabalho é demonstrar os motivos da existência e da imprescindibilidade dos Tribunais de Contas no Brasil, principalmente quando observados sob o prisma da eficiência na administração pública do país. Também visa retratar algumas deficiências do sistema político brasileiro, notadamente no âmbito dos Poder Legislativo, as quais impedem o alcance da máxima eficiência no trato da coisa pública. Neste trabalho, o conceito de eficiência foi abordado em seu mais amplo sentido, não se bastando à economicidade e à celeridade na resolução dos problemas públicos, mas abrangendo, também, a moralidade e a finalidade pública.

Introducion: Osteosarcoma is a primary malignant bone tumor most commonly found in long bones. However, in the oral cavity it mainly affects the ramus and angle of the mandible. Objetive: To present a case of osteolytic osteosarcoma of the mandible and discuss the difficulties of diagnosis and treatment. Case Report: A 22-year-old white female patient, non-smoker and non-drinker attended the stomatology service with complaints of increased volume on the right side of the mandible, exhibiting premolar and molar mobility in that area.Periapical and occlusal radiographs were performed and showed presence of radiolucent area and floating teeth, confirmed by a panoramic radiography showing involvement of the mandibular ramus. Two biopsies were performed in the region with inconclusive results for malignancy. The diagnostic hypothesis was osteosarcoma. A CT scan showed bone loss, floating teeth and involvement of areas adjacent to the tumor lesion and lymph nodes. The patient was referred to the oncology hospital and a frozen section biopsy was conclusive for osteosarcoma, with removal of the base and most of the right and left mandible ramus, followed by reconstruction with titanium plate. The tumor recurred and a new surgery, radiotherapy and chemotherapy were performed in an attempt to improve the clinical condition, with failure and death after four years of initial diagnosis and tumor mutation for rhabdomyosarcoma. Conclusion: Imaging and even histopathological outpatient exams were not able to promote the final diagnosis of osteosarcoma, impairing treatment and favoring recurrence and patient death. Key words: Osteosarcoma. Bone tumor. Diagnostic imaging.

A pandemia global de COVID-19 trouxe inúmeros desafios para a humanidade. O COVID-19 engatilha um agressivo processo inflamatório em alguns indivíduos denominado de “tempestade de citocinas” desregulando o sistema imunológico e favorecendo a acometimento de órgãos e às vezes resultando em fatalidade. Em tempos de isolamento social comportamentos sedentários podem afligir a população, no entanto, uma parcela dos indivíduos está se exercitando em domicílio. Evidências demonstram que o exercício físico agudo aeróbio e de moderada intensidade até 60 minutos favorece a manutenção de um sistema imunológico saudável, enquanto que exercícios extenuantes predispõe o risco de infecção do trato respiratório superior (ITRS). Já o exercício físico crônico promove um ambiente anti-inflamatório, essencial para o combate de inúmeras co-morbidades e o envelhecimento precoce. Portanto, o exercício físico de intensidade, volume e duração controlados e realizados com segurança promovem um ambiente anti-inflamatório favorável, embora sejam necessários estudos para verificar se existe esta proteção contra o COVID-19. Assim, o objetivo deste artigo de opinião é discutir a imunologia do exercício e sua possível proteção contra o COVID-19 e guiar recomendações práticas de exercícios físicos que possam ser realizadas no próprio domicílio.

OBJECTIVES To compare the aerobic and anaerobic energy system contribution during 1500m running between collegiate untrained (UT) and endurance trained (ET) subjects.METHODS Five Asian UT (age: 23.8 ± 0.4 yrs, body fat %: 15.9 ± 5.7 %, height: 174.0 ± 4.1 cm, weight: 65.5 ± 4.1 kg) and 5 Asian ET male participants (age: 24.4 ± 3.9 yrs, body fat %: 12.9 ± 6.9 %, height: 169.4 ± 5.1 cm, weight: 60.6 ± 8.1 kg) participated in this study. Participants attended 3 sessions to determine their body composition, submaximal and maximal oxygen consumption (VO2max) test, 1500m track running session (RS) and 1500m treadmill RS. The maximally accumulated oxygen deficit (MAOD) method was used to calculate energy system contribution.RESULTS The times for the 1500m track run for the UT and ET were 428.0 ± 48.7 and 331.6 ± 14.0 seconds (p=0.004) respectively. There were no significant differences in VO2 between the 1500m track and treadmill RS indicating the participants ran to their personal best times for both trials. The mean VO2max(mL•kg-1•min-1) were significantly different between UT (45.1 ± 5.0) and ET participants (58.3 ± 2.2) (p=0.002). The mean relative contributions of the aerobic and anaerobic energy system during 1500m running were significantly different for the UT, 65.4 ± 7.0%, 34.6 ± 7.0 and ET, 75.7 ± 1.5%, 24.3 ± 1.5 % (p =0.011).CONCLUSIONS The point of equal contribution of the aerobic and the anaerobic systems occurred after thirty to forty seconds of intensive exhaustive running after which the aerobic contribution continues to increase while the anaerobic contribution decreases with increasing duration. By the end of 60th second of exhaustive running, the ET mean aerobic contribution is 71.5% compared to the UT’s 58.6%. This finding suggests a greater reliance on the aerobic energy system by the ET.

Introduction: The increase in the geriatric population in industrialized countries also increases the rate at which this group utilizes emergency services. Evaluation of this patient group is not specific to a single discipline, but requires a multidisciplinary approach. Information obtained by examining emergency service use among geriatric patients can inform us of approaches to improve hospital efficiency and potentially reduce the morbidity and mortality rates.

Metarial and Method: This study investigated the retrospective records of geriatric patients who presented to emergency services during 2016 XXXTraining and Research Hospital, Turkey. Demographic characteristics, diagnoses, hospitalization rates, hospitalization according to clinics, seasonal characteristics, duration of hospital, and patient outcomes were evaluated. Study data were evaluated using the SPSS 20.00 statistical program.

Results: A total of 314.178 patients opted for emergency services during 2016, and 29.163 (9.2%) were 65 years old and older. Among these patients, 10.545 were hospitalized, of whom 4.246 (40.2%) were aged 65 years or older. The most frequently utilized hospital units were the cardiology (n = 723, 17.02%), the neurology (n = 717, 16.88%), and the chest diseases (n = 674, 15.87%).

Discussion and Conclusion : The geriatric population requires that necessary changes should be made in healthcare structures. Our study, which evaluates hospitalization rates and health status in geriatric population at a provincial which can also provide a regional level, can help in making patient admission, follow-up, and rehabilitation more comprehensive.
