Hypertension is one of the primary modifiable risk factors for morbidity and mortality worldwide, being a major risk factor for coronary artery disease, stroke, and kidney failure. Furthermore, it is highly prevalent, affecting more than one-third of the global population.
Blood pressure measurement is a MANDATORY procedure in any medical care setting and is carried out by various healthcare professionals. However, it is still commonly performed without the necessary technical care. Since the diagnosis relies on blood pressure measurement, it is clear how important it is to handle the techniques, methods, and equipment used in its execution with care.
It should be emphasized that once the diagnosis is made, all short-term, medium-term, and long-term investigations and treatments are based on the results of blood pressure measurement. Therefore, improper techniques and/or equipment can lead to incorrect diagnoses, either underestimating or overestimating values, resulting in inappropriate actions and significant health and economic losses for individuals and nations.
Once the correct diagnosis is made, as knowledge of the importance of proper treatment advances, with the adoption of more detailed normal values and careful treatment objectives towards achieving stricter blood pressure goals, the importance of precision in blood pressure measurement is also reinforced.
Blood pressure measurement (described below) is usually performed using the traditional method, the so-called casual or office measurement. Over time, alternatives have been added to it, through the use of semi-automatic or automatic devices by the patients themselves, in waiting rooms or outside the office, in their own homes, or in public spaces. A step further was taken with the use of semi-automatic devices equipped with memory that allow sequential measurements outside the office (ABPM; or HBPM) and other automatic devices that allow programmed measurements over longer periods (HBPM).
Some aspects of blood pressure measurement can interfere with obtaining reliable results and, consequently, cause harm in decision-making. These include the importance of using average values, the variation in blood pressure during the day, and short-term variability. These aspects have encouraged the performance of a greater number of measurements in various situations, and different guidelines have advocated the use of equipment that promotes these actions. Devices that perform HBPM or ABPM, which, in addition to allowing greater precision, when used together, detect white coat hypertension (WCH), masked hypertension (MH), sleep blood pressure alterations, and resistant hypertension (RHT) (defined in Chapter 2 of this guideline), are gaining more and more importance.
Taking these details into account, we must emphasize that information related to diagnosis, classification, and goal setting is still based on office blood pressure measurement, and for this reason, all attention must be given to the proper execution of this procedure.
La hipertensión arterial (HTA) es uno de los principales factores de riesgo modificables para la morbilidad y mortalidad en todo el mundo, siendo uno de los mayores factores de riesgo para la enfermedad de las arterias coronarias, el accidente cerebrovascular (ACV) y la insuficiencia renal. Además, es altamente prevalente y afecta a más de un tercio de la población mundial.
La medición de la presión arterial (PA) es un procedimiento OBLIGATORIO en cualquier atención médica o realizado por diferentes profesionales de la salud. Sin embargo, todavía se realiza comúnmente sin los cuidados técnicos necesarios. Dado que el diagnóstico se basa en la medición de la PA, es claro el cuidado que debe haber con las técnicas, los métodos y los equipos utilizados en su realización.
Debemos enfatizar que una vez realizado el diagnóstico, todas las investigaciones y tratamientos a corto, mediano y largo plazo se basan en los resultados de la medición de la PA. Por lo tanto, las técnicas y/o equipos inadecuados pueden llevar a diagnósticos incorrectos, subestimando o sobreestimando valores y resultando en conductas inadecuadas y pérdidas significativas para la salud y la economía de las personas y las naciones.
Una vez realizado el diagnóstico correcto, a medida que avanza el conocimiento sobre la importancia del tratamiento adecuado, con la adopción de valores de normalidad más detallados y objetivos de tratamiento más cuidadosos hacia metas de PA más estrictas, también se refuerza la importancia de la precisión en la medición de la PA.
La medición de la PA (descrita a continuación) generalmente se realiza mediante el método tradicional, la llamada medición casual o de consultorio. Con el tiempo, se han agregado alternativas a través del uso de dispositivos semiautomáticos o automáticos por parte del propio paciente, en salas de espera o fuera del consultorio, en su propia residencia o en espacios públicos. Se dio un paso más con el uso de dispositivos semiautomáticos equipados con memoria que permiten mediciones secuenciales fuera del consultorio (AMPA; o MRPA) y otros automáticos que permiten mediciones programadas durante períodos más largos (MAPA).
Algunos aspectos en la medición de la PA pueden interferir en la obtención de resultados confiables y, en consecuencia, causar daños en las decisiones a tomar. Estos incluyen la importancia de usar valores promedio, la variación de la PA durante el día y la variabilidad a corto plazo. Estos aspectos han alentado la realización de un mayor número de mediciones en diversas situaciones, y diferentes pautas han abogado por el uso de equipos que promuevan estas acciones. Los dispositivos que realizan MRPA o MAPA, que además de permitir una mayor precisión, cuando se usan juntos, detectan la hipertensión de bata blanca (HBB), la hipertensión enmascarada (HM), las alteraciones de la PA durante el sueño y la hipertensión resistente (HR) (definida en el Capítulo 2 de esta guía), están ganando cada vez más importancia.
Teniendo en cuenta estos detalles, debemos enfatizar que la información relacionada con el diagnóstico, la clasificación y el establecimiento de objetivos todavía se basa en la medición de la presión arterial en el consultorio, y por esta razón, se debe prestar toda la atención a la ejecución adecuada de este procedimiento.
A hipertensão arterial (HA) é um dos principais fatores de risco modificáveis para morbidade e mortalidade em todo o mundo, sendo um dos maiores fatores de risco para doença arterial coronária, acidente vascular cerebral (AVC) e insuficiência renal. Além disso, é altamente prevalente e atinge mais de um terço da população mundial.
A medida da PA é procedimento OBRIGATÓRIO em qualquer atendimento médico ou realizado por diferentes profissionais de saúde. Contudo, ainda é comumente realizada sem os cuidados técnicos necessários. Como o diagnóstico se baseia na medida da PA, fica claro o cuidado que deve haver com as técnicas, os métodos e os equipamentos utilizados na sua realização.
Deve-se reforçar que, feito o diagnóstico, toda a investigação e os tratamentos de curto, médio e longo prazos são feitos com base nos resultados da medida da PA. Assim, técnicas e/ou equipamentos inadequados podem levar a diagnósticos incorretos, tanto subestimando quanto superestimando valores e levando a condutas inadequadas e grandes prejuízos à saúde e à economia das pessoas e das nações.
Uma vez feito o diagnóstico correto, na medida em que avança o conhecimento da importância do tratamento adequado, com a adoção de valores de normalidade mais detalhados e com objetivos de tratamento mais cuidadosos no sentido do alcance de metas de PA mais rigorosas, fica também reforçada a importância da precisão na medida da PA.
A medida da PA (descrita a seguir) é habitualmente feita pelo método tradicional, a assim chamada medida casual ou de consultório. Ao longo do tempo, foram agregadas alternativas a ela, mediante o uso de equipamentos semiautomáticos ou automáticos pelo próprio paciente, nas salas de espera ou fora do consultório, em sua própria residência ou em espaços públicos. Um passo adiante foi dado com o uso de equipamentos semiautomáticos providos de memória que permitem medidas sequenciais fora do consultório (AMPA; ou MRPA) e outros automáticos que permitem medidas programadas por períodos mais prolongados (MAPA).
Alguns aspectos na medida da PA podem interferir na obtenção de resultados fidedignos e, consequentemente, causar prejuízo nas condutas a serem tomadas. Entre eles, estão: a importância de serem utilizados valores médios, a variação da PA durante o dia e a variabilidade a curto prazo. Esses aspectos têm estimulado a realização de maior número de medidas em diversas situações, e as diferentes diretrizes têm preconizado o uso de equipamentos que favoreçam essas ações. Ganham cada vez mais espaço os equipamentos que realizam MRPA ou MAPA, que, além de permitirem maior precisão, se empregados em conjunto, detectam a HA do avental branco (HAB), HA mascarada (HM), alterações da PA no sono e HA resistente (HAR) (definidos no Capítulo 2 desta diretriz).
Resguardados esses detalhes, devemos ressaltar que as informações relacionadas a diagnóstico, classificação e estabelecimento de metas ainda são baseadas na medida da PA de consultório e, por esse motivo, toda a atenção deve ser dada à realização desse procedimento.

ABSTRACT In the Brazilian Cerrado, phytonematodes, phytonematodes are a challenge for agriculture, and the association of forms of control is the best strategy to be used in coexistence with this pathogen. Faced with this problem, this study aimed to evaluate the efficiency of cover crops and biocontrol agents in the management of nematodes in soybean. For each nematode species under study (Meloidogyne incognita and Pratylenchus brachyurus), two experiments were carried out under greenhouse conditions in a completely randomized design arranged in a 6 × 2 factorial scheme with eight replications. Six cover crops (millet ADRG 9050, millet ADR 300, Urochloa ruziziensis, Crotalaria ochroleuca, C. spectabilis, and corn hybrid DKB 290) and two treatments (treated or not with Bacillus subtilis and B. methylotrophicus - 1×106 CFU per seed) were evaluated. The cover crops were sown in soil infested with nematodes and then soybeans were sown under the straw, and cultivated for 45 and 60 days, for M. incognita and P. brachyurus, respectively. Fresh root mass, total nematode population, and the number of nematodes per gram of root were evaluated. The association of microorganisms with C. spectabilis, U. ruziziensis, and millet ADR 300 conferred an additional effect in reducing the population of P. brachyurus. For M. incognita, the association was successful only for combining C. spectabilis with B. methylotrophicus. DKB 290 corn, when treated with B. methylotrophicus, had the nematode population per gram of soybean root reduced by 90% compared to plants that did not receive biological treatment.
RESUMO No Cerrado brasileiro, os fitonematoides são um desafio para agricultura, sendo a associação de formas de controle a melhor estratégia a ser utilizada na convivência com esse patógeno. Diante dessa problemática, o objetivo desse trabalho foi avaliar a eficiência de plantas de cobertura e agentes de biocontrole no manejo de nematoides na cultura da soja. Foram desenvolvidos dois ensaios em condições de casa de vegetação para os nematoides Meloidogyne incognita e Pratylenchus brachyurus, em delineamento inteiramente casualizado, em esquema fatorial 6 (plantas de cobertura: milheto ADRG 9050, milheto ADR 300, Urochloa ruziziensis, Crotalaria ochroleuca, C. spectabilis e milho DKB 290) × 2 (tratados ou não com Bacillus subtilis e B. methylotrophicus - 1×106 UFC por semente), com oito repetições. As plantas de cobertura foram semeadas em solo infestado com nematoides e na sequência semeada soja sob a palha, e cultivada por 45 e 60 dias, para M. incognita e P. brachyurus, respectivamente. Foram avaliadas a massa fresca de raízes e o número de nematoides totais e por grama de raiz. A associação dos microrganismos com C. spectabilis, U. ruziziensis e milheto ADR 300 conferiram efeito adicional na redução da população de P. brachyurus. Para a espécie M. incognita a associação foi bem sucedida apenas para a combinação da C. spectabilis com B. methylotrophicus. O milho DKB 290, quando tratado com B. methylotrophicus, teve a população do nematoide por grama de raiz da soja reduzida em 90 % em comparação às plantas que não receberam o tratamento biológico.

RESUMO: Os anéis de ossículos esclerais têm sua função relacionada à proteção mecânica, fixação muscular, suporte para o formato do bulbo ocular e acomodação visual, contudo existem poucos relatos morfobiométricos sobre esses anéis em diferentes espécies de Testudines. Desta forma, foi realizada a avaliação morfobiométrica, por ultrassom (US) e tomografia computadorizada (TC), dos anéis de ossículos esclerais em uma tartaruga verde (Chelonia mydas), um tigre-d’água (Trachemys dorbigni) e um jabuti-piranga (Chelonoidis carbonarius). Foram realizadas US e TC dos anéis esclerais dos três animais para identificação anatômica, espessura, densidade, largura e diâmetros. A US e a TC dos três animais mostraram estruturas circulares únicas e contínuas, localizadas no polo anterior. Estas estruturas foram facilmente observadas na C. mydas, cujos anéis eram os maiores, mais espessos e mais largos. A TC da T. dorbigni apresentou dimensões reduzidas e os ossículos foram dificilmente identificados. A densidade óssea na região superior foi maior comparativamente a parte inferior de cada anel, em todos os animais. Exames de imagem não invasivos mostraram-se bons instrumentos para estudo do esqueleto escleral. Os anéis de ossículos esclerais dos três espécimes apresentaram semelhanças morfológicas gerais e a TC permitiu visualizar um maior número de detalhes da morfologia óssea do anel.
ABSTRACT: The scleral ossicle rings function has been related to mechanical protection, muscle fixation, support for eyeball shape and visual accommodation. There are few morphobiometric reports on these rings in different Testudines species, and we performed ultrasound (US) and computed tomography (CT) of the scleral ossicle rings in one green turtle (Chelonia mydas), one black-bellied slider (Trachemys dorbigni) and one red-footed tortoise (Chelonoidis carbonarius). The US and CT of the ossicle rings were performed for anatomical identification. The thickness, density, width, and diameters of each ring were measured. The US and CT of the scleral ossicle rings of three animals showed single and continuous circular structures, located in the anterior pole. These structures were easily observed in C. mydas, whose rings were the biggest, thickest and widest. The T. dorbigni CT presented decreased dimensions and the ossicles were the most difficult to identify. Bone density in the superior region was greater than in the inferior of each ring in all animals. Non-invasive imaging exams are good tools to study the anatomy of the ocular skeleton. The scleral ossicle rings of the three specimens presented general morphological similarities and CT enabled visualizing a greater number of details of the ring bone morphology.

Abstract The Santos Basin (SB) is the main petroliferous basin in the Brazilian continental margin and one of the most studied marine areas in Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially in the deep sea, to establish the baseline of essential ocean variables in different ecosystems for future monitoring programs. The Brazilian energy company Petrobras planned and executed 24 oceanographic cruises over a period of 2 years to assess the benthic (SANSED cruise) and pelagic (SANAGU cruise) systems of the SB (356 days at sea in 2019 and 2021/2022). These efforts were part of the Santos Project, which comprised a comprehensive environmental study aimed at investigating benthic and pelagic variables to characterize ecology, biogeochemistry, thermohaline properties of water masses, and ocean circulation patterns, geomorphology, and sedimentology, as well as organic and inorganic chemistry. Here we present the detailed sampling designs and the field methods employed on board, during the SB scientific cruises. All sampling protocols were based on standardized approaches. For the benthos analyses, triplicate sediment samples were performed using a GOMEX-type box corer (0.25 m²) or a large modified Van Veen grab (0.75 m²) at 100 stations ranging from 25 to 2400 m depth. At each station, 25 geochemical and physico-chemical parameters were analyzed in addition to micro-, meio-, and macrofauna and living foraminifera samples. For the pelagic system, 60 stations were selected to investigate the plankton community, ranging in size from pico- to macroplankton, through vertical, horizontal, and oblique net hauls (20, 200, and 500 μm mesh size), as well as 25 biogeochemical parameters collected with an aid of a CTD-rosette sampler. Part of this scientific information also serves the Regional Environmental Characterization Project (PCR-BS) in support of Petrobras’ Santos Basin drilling licensing process led by the Brazilian Environmental Agency – IBAMA. This project contributes to the sustainable development of the SB, in line with the guidelines of the United Nations Decade of Ocean Science for Sustainable Development.

ABSTRACT Background: The increase in agricultural production requires sustainable alternatives development for reusing the waste generated, such as bovine manure, to obtain ecological, environmental, and economic benefits. In addition, proper fertilization is one of the main steps in the production of forest species seedlings. Thus, this study aimed to characterize the effect of different substrates formulations based on bovine manure and types of fertilizers on the quality of C. montevidense seedlings and verify if the field confirms the nurseries’ responses. The treatments consisted of three BM-based substrates combinations (S0 - control, no manure; S30 - 30% BM; and S60 - 60% BM) and four types of base fertilizers [Control: no fertilizer, FRF - Fast Release Fertilizer (NPK + fritted trace elements), FRF2 - twice as used in FRF and CRF - Controlled Release Fertilizer]. The substrates quality and the seedlings’ morphophysiological attributes were determined 160 days after sowing, then conducting the best treatments to the field. Results: We verified that the use of bovine manure improved the physical and chemical properties of the substrates. For the C. montevidense cultivation, 30% BM plus CRF provided the best seedling development. The substrate used in the seedlings production influenced the post-planting performance of C. montevidense, and the bovine manure use allows for more significant plant growth in the field. Conclusion: For the cultivation of Citharexylum montevidense, it is recommended to use substrates composed of 30% of bovine manure, associated with 6 g L-1 of controlled-release fertilizer, as it provides higher quality seedlings in shorter production time in the nursery.

ABSTRACT Background: Direct sowing technique is considered a promising tool for reducing costs and increasing species diversity in restoration projects. However, several factors can limit its success, making it necessary for methodological adjustments to be made in order to maximize the emergence, establishment and initial growth of plants. This study aimed to evaluate the influence of the use of fungus Trichoderma asperelloides and hydrogel in the enrichment direct sowing as a strategy to enrich the area in the initial restoration process. The forest species studied were Balfourodendron riedelianum, Cedrela fissilis, Luehea divaricata, Enterolobium contortisiliquum and Parapiptadenia rigida. The experiment was conducted in a factorial design testing absence or presence of the T. asperelloides and absence or presence of hydrogel. Two experiments were established: in the nursery, we evaluations of the emergence of the seedlings were carried out; in the field, we evaluated emergence, survival, height and stem diameter. Results: Under nursery conditions, inoculation and the use of hydrogel did not influence the emergence of species tested. Direct sowing proved to be a promising technique for the enrichment of young restoration plantations in subtropical regions with E. contortisiliquum, P. rigida and C. fissilis. B. riedelianum and L. divaricata seeds did not germinate in the field. Conclusion: The use of T. asperelloides is an efficient strategy to enhance the results of direct sowing, capable of providing higher rates of emergence for E. contortisiliqumm and P. rigida and maximizing the growth in height of E. contortisiliqumm. Under high pluviometric intensity, the use of the hydrogel does not influence the emergence and morphological attributes of the species studied.

ABSTRACT Introduction. The behavior of COVID-19 is influenced by diverse social differentials that transcend demographic variables and include morbidity, the conditions of their homes, family dynamics, job performance, gender roles and stereotypes, care tasks, habits, and behaviors of life and consumption, among others. Methods. Statistical and demographic analysis and tools of metric studies of the information were used. Results and Discussion. The research showed the importance of incorporating into the analysis of the behavior of COVID-19 in Cuba the influence of social and epidemiological differentials determined by skin color, marital status, employment status, income levels, types of families, mobility, hygienic environmental conditions, access to health services, among others, which can place populations in greater or lesser conditions of vulnerability. Conclusions: The composition and dynamics of the population together with other social differentials are determinants of the behavior and expression of the pandemic. The crossing of epidemiological factors with the analysis of containment measures and the composition and structure of the affected population allows for the design of health policies that are more adjusted to the needs of the pandemic. Distance psychological counseling makes it possible to identify and deal with situations related to confinement and changes in life routines that affect the mental health of different groups of people.
RESUMEN Introducción. El comportamiento de la COVID-19 está influenciado por diferenciales sociales que trascienden las variables demográficas e incluyen la morbilidad, las condiciones de sus viviendas, las dinámicas familiares, el desempeño laboral, los roles y estereotipos de género, las tareas de cuidado, los hábitos y comportamientos de vida y consumo, entre otros. Métodos. Se empleó el análisis estadístico y demográfico y herramientas de los estudios métricos. Resultados y Discusión. La investigación mostró la importancia de incorporar a los análisis del comportamiento de la COVID-19 en Cuba la influencia de diferenciales sociales y epidemiológicos determinados por el color de la piel, el estado conyugal, la situación laboral, los niveles de ingreso, los tipos de familias, la movilidad, las condiciones higiénico ambientales, el acceso a los servicios de salud, entre otros, que pueden ubicar a las poblaciones en mayores o menores condiciones de vulnerabilidad. Conclusiones, la composición y la dinámica de la población junto a otros diferenciales sociales son determinantes del comportamiento de la pandemia. El cruzamiento de los factores epidemiológicos con el análisis de las medidas de contención y la composición y estructura de población afectada permite diseñar políticas sanitarias más ajustadas a las necesidades de la pandemia. La orientación psicológica a distancia permite identificar y atender situaciones vinculadas al confinamiento y los cambios en las rutinas de vida que afectan la salud mental de diferentes grupos de personas.

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

Abstract This study aimed to determine whether the addition of green propolis extract to the diet of laying hens would improve egg quality and bird performance and decrease bacterial contamination of eggs. Forty-five brown Hy-line laying hens were used, divided into five groups with three replicates each and three animals per cage: T0 - diet without propolis; T5 - 5 grams of propolis per kg of feed; T10 - 10 grams of propolis per kg of feed; T20 - 20 grams of propolis per kg of feed and T30 - 30 grams of propolis per kg of feed. The quality of fresh eggs was made on day 21 of the experiment, and eggs were stored for 21 days. Greater specific gravity was observed in fresh eggs in T5 birds and stored eggs for T10. TBARS in fresh eggs, we found that T30 eggs had lower levels compared to other treatments. T20 eggs had the lowest total bacterial count and the lowest total coliform count in the eggshells of T10 and T20 chickens. The count of E. coli in the peel was lower for T20 and T30 than T0 and T5. The consumption of propolis did not interfere with the hens’ egg production rate but reduced food intake and consequently reduced feed conversion. We concluded that the addition of green propolis in the diet of laying birds proved efficient in reducing bacterial contamination in the eggshells and reducing the lipid peroxidation of fresh and stored eggs.

RESUMO Objetivo: Este estudo se propõe a descrever a eficiência de hospitais privados no Brasil, bem como compreender a influência da estrutura de propriedade, da especialização, da acreditação e da atividade de ensino sobre a eficiência de hospitais privados. Originalidade/valor: Os achados descrevem a eficiência de hospitais privados que se destacam por sua busca pela certificação de qualidade e segurança, e investigam fatores controversos da literatura sobre a eficiência hospitalar. Além disso, a pesquisa contribui para o desenvolvimento da literatura nacional sobre a eficiência de hospitais no Brasil, por meio de uma análise em dois estágios. Design/metodologia/abordagem: São estimadas as eficiências de 98 hospitais da Associação Nacional de Hospitais Privados (ANAHP) por meio da modelagem Data Envelopment Analysis (DEA). Para tal, foram selecionados três inputs e três outputs referentes ao desempenho dos hospitais no ano de 2017. No primeiro estágio, foram analisadas as eficiências, orientadas aos inputs e com a utilização de uma variável não discricionária. No segundo, foram estimadas medidas bootstrapped e investigadas, por meio de modelos econométricos, as influências dos fatores da eficiência hospitalar. Resultados: Os resultados possibilitam descrever aspectos da gestão dos recursos, relacionados aos inputs e outputs investigados, para a melhoria da eficiência nos hospitais privados no Brasil, além da compreensão da influência dos fatores estrutura de propriedade, especialização e acreditação sobre a eficiência de hospitais privados.
ABSTRACT Purpose: This study aims to describe the efficiency of private hospitals in Brazil and to understand the influence of property structure, specialization, accreditation, and teaching activity on the efficiency of private hospitals. Originality/value: Our findings suggested that private hospitals’ efficiency stands out due to their quest for quality and safety certification and investigates controversial factors in the hospital efficiency literature. Besides, it contributes to the development of the national literature as regards hospitals efficiency in Brazil through a two-stage analysis. Design/methodology/approach: The efficiencies of 98 hospitals of the National Association of Private Hospitals (ANAHP) were estimated through the modeling Data Envelopment Analysis (DEA). Three inputs and three outputs were selected referring to the performance of hospitals in the year 2017. In the first stage, the input-oriented efficiencies were analyzed using a non-discretionary variable. In the second, bootstrapped measures were estimated, and the influences of hospital efficiency factors were investigated through econometric models. Findings: The results enabled the description of resource management aspects related to the inputs and outputs investigated, to improve efficiency in private hospitals in Brazil, and to understand the influence of ownership, specialization, and accreditation factors on the efficiency of private hospitals.

Abstract This study aimed to prepare hydrogel containing Cymbopogon citratus (DC.) Stapf, Poaceae, volatile oil encapsulated in poly (d,l-lactide-co-glycolide) nanoparticles and to evaluate its in vitro anti-herpetic activity. Polymeric nanoparticles were prepared by solvent emulsification-diffusion method and incorporated in carbomer hydrogels. In vitro release profiles for the nanogel, loaded nanoparticles and hydrogel containing free oil were evaluated by dialysis. Inhibitory activities against Herpes simplex for the formulations were investigated in Vero cells. Hydrogel was developed using nanoparticles with mean diameter of 217.1 nm and negative Zeta potential (−20.5 mV). Volatile oil release profile showed a biphasic pattern with an initial faster release and subsequent sustained phase in all formulations. Nanogel strongly inhibited virus in a non-cytotoxic concentration, 42.16 times lower than free oil, 8.76 and 2.23 times than loaded nanoparticles and hydrogel containing free oil, respectively. These results highlight the potential of nanogel to protect oil against volatilization, control release and improve its anti-herpetic activity.

RESUMO Avanços na compreensão e no manejo da distrofia muscular de Duchenne (DMD) ocorreram desde a publicação de diretrizes internacionais em 2010. Nosso objetivo foi elaborar um consenso nacional baseado em evidências de cuidado multidisciplinar dos pacientes com DMD no Brasil. Utilizamos a técnica de Delphi combinada com revisão sistemática da literatura de 2010 a 2016 classificando níveis de evidência e graus de recomendação. Nossas recomendações foram divididas em duas partes. Apresentamos aqui a parte 1, descrevendo a metodologia utilizada e conceitos gerais da doença, e fornecemos recomendações sobre diagnóstico, tratamento com corticosteroides e novas perspectivas de tratamentos medicamentosos. As principais recomendações: 1) testes genéticos deveriam ser a primeira linha para confirmação de casos suspeitos; 2) pacientes com diagnóstico de DMD devem receber corticosteroides; 3) por enquanto, a falta de publicações de resultados dos ensaios clínicos de fase 3, dificulta recomendações de uso medicamentos que “saltam exons” ou “passam” por código de parada prematura.
ABSTRACT Significant advances in the understanding and management of Duchenne muscular dystrophy (DMD) took place since international guidelines were published in 2010. Our objective was to provide an evidence-based national consensus statement for multidisciplinary care of DMD in Brazil. A combination of the Delphi technique with a systematic review of studies from 2010 to 2016 was employed to classify evidence levels and grade of recommendations. Our recommendations were divided in two parts. We present Part 1 here, where we describe the guideline methodology and overall disease concepts, and also provide recommendations on diagnosis, steroid therapy and new drug treatment perspectives for DMD. The main recommendations: 1) genetic testing in diagnostic suspicious cases should be the first line for diagnostic confirmation; 2) patients diagnosed with DMD should have steroids prescribed; 3) lack of published results for phase 3 clinical trials hinders, for now, the recommendation to use exon skipping or read-through agents.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

Two new diastereoisomeric cadinanes sesquiterpenes 3,9-dihydroxycalamenene (1-2), along with the known 3-hydroxycalamen-8-one (3) and aristelegone-A (4), were isolated from ethyl acetate extract of Phomopsis cassiae, an endophytic fungus in Cassia spectabilis. Their structures, including relative stereochemistry, were determined on the basis of detailed interpretation of 2D NMR spectra and comparison with related known compounds. Compounds 1-4 displayed antifungal activity against the phytopathogenic fungi Cladosporium cladosporioides and C. sphaerospermum, as well as inhibition of acetylcholinesterase.

Objetivo: Avaliar o acúmulo de ferro em diferentes órgãos por meio da ressonância nuclear magnética T2* e correlacionar os resultados aos níveis de ferritina sérica, ferro plasmático lábil e outros órgãos envolvidos. Métodos: Foram avaliados retrospectivamente 115 pacientes talassêmicos (sendo 65 mulheres). A concentração hepática de ferro foi determinada em biópsia de 11 pacientes; os resultados foram comparados com os valores de T2* fígado. Resultados: a ferritina sérica média foi de 2.676,5 +/- 2.051,7 ng/mL. O ferro plasmático lábil foi anormal (> 0,6 Unidades/mL) em 48/83 pacientes (57%). A média dos valores de T2* no fígado foi 3,91 ± 3,95 ms, sugerindo siderose hepática em 92,1% pacientes. A média do T2* cardíaco foi de 24,96 ± 14,17 ms e 36% dos pacientes apresentavam siderose cardíaca (T2* < 20ms), dos quais 19% (22/115) já apresentavam sobrecarga cardíaca grave (T2* < 10 ms). A média de T2* no pâncreas foi de 11,12 ± 11,20 ms, perfazendo um total de 83,5% de pacientes com sobrecarga de ferro pancreático (T2* < 21 ms). Houve correlação significativa, curvilínea e inversa entre T2* fígado e a concentração de ferro hepática (r = −0,878; p <0,001) e correlação moderada entre T2* pâncreas e T2* miocárdio (r = 0,546; p <0,0001). Conclusão: Uma elevada taxa de acometimento hepático, pancreático e cardíaco por sobrecarga férrica foi demonstrada. Os níveis de ferritina não puderam prever sobrecarga de ferro hepático, cardíaco ou pancreáticos medidos por meio da ressonância nuclear magnética T2*. Não houve correlação entre a sobrecarga de ferro no fígado, pâncreas e miocárdio, nem entre a ferritina e os níveis plasmáticos de ferro sérico e os valores de T2* no fígado, coração e pâncreas.
ABSTRACT Objectives: To evaluate the use of magnetic resonance imaging in patients with β-thalassemia and to compare T2* magnetic resonance imaging results with serum ferritin levels and the redox active fraction of labile plasma iron. Methods: We have retrospectively evaluated 115 chronically transfused patients (65 women). We tested serum ferritin with chemiluminescence, fraction of labile plasma iron by cellular fluorescence and used T2* MRI to assess iron content in the heart, liver, and pancreas. Hepatic iron concentration was determined in liver biopsies of 11 patients and the results were compared with liver T2* magnetic resonance imaging. Results: The mean serum ferritin was 2,676.5 +/- 2,051.7 ng/mL. A fraction of labile plasma iron was abnormal (> 0,6 Units/mL) in 48/83 patients (57%). The mean liver T2* value was 3.91 ± 3.95 ms, suggesting liver siderosis in most patients (92.1%). The mean myocardial T2* value was 24.96 ± 14.17 ms and the incidence of cardiac siderosis (T2* < 20 ms) was 36%, of which 19% (22/115) were severe cases (T2* < 10 ms). The mean pancreas T2* value was 11.12 ± 11.20 ms, and 83.5% of patients had pancreatic iron deposition (T2* < 21 ms). There was significant curvilinear and inverse correlation between liver T2* magnetic resonance imaging and hepatic iron concentration (r= −0.878; p < 0.001) and moderate correlation between pancreas and myocardial T2* MRI (r = 0.546; p < 0.0001). Conclusion: A high rate of hepatic, pancreatic and cardiac impairment by iron overload was demonstrated. Ferritin levels could not predict liver, heart or pancreas iron overload as measured by T2* magnetic resonance imaging. There was no correlation between liver, pancreas, liver and myocardial iron overload, neither between ferritin and fraction of labile plasma iron with liver, heart and pancreas T2* values
