A eficácia da Estratégia Saúde da Família e do Tratamento Diretamente Observado no controle da Tuberculose
Authors: Santiago Baldan Sueli , Ferraudo Antonio Sergio , De Andrade Monica 
Published: February 2017

Justificativa e objetivos: O fortalecimento da Atenção Básica à Saúde, tornando-a protagonista no cuidado da pessoa com tuberculose (TB), favorece a identificação de sintomáticos respiratórios, assim como o diagnóstico e tratamento precoce, diminuindo a transmissão da doença e favorecendo a adesão ao tratamento. Este estudo procurou investigar a eficácia da cobertura da Estratégia Saúde da Família (ESF) e da estratégia de Tratamento Diretamente Observado (TDO) no controle do abandono de tratamento para TB. Métodos:
Estudo exploratório, a partir de dados secundários. As variáveis investigadas foram: coeficiente de incidência de tuberculose (CI-TB), percentual de cobertura por ESF, percentual de abandono de tratamento e percentual de oferta de TDO, no Mato Grosso do Sul. Foi utilizada a análise de agrupamento por método hierárquico para buscar padrões contidos no conjunto de dados. Resultados: Os dados obtidos indicam que há grupos de municípios em que a cobertura por ESF e TDO contribui para adesão ao tratamento e controle do número de casos de TB, enquanto que para outros municípios estas medidas não têm sido eficazes na redução do CI-TB e do abandono ao tratamento. A doença se distribui de forma heterogênea no estado. Conclusão: Profissionais e gestores da saúde precisam conhecer os padrões da tuberculose, em suas regiões, priorizando e planejando ações que contribuam para um efetivo
controle da transmissão da doença e maior adesão ao tratamento em sua comunidade.
Cirurgia de vitrectomia com equipamento de 27 gauge
Authors: Moreira Júnior Carlos Augusto , Ávila Marcos Pereira de 
Published: February 2017

No vídeo a seguir, mostramos duas cirurgias de vitrectomia via pars plana utilizando o sistema de 27 gauge. O equipamento utilizado foi o constellationR (Alcon - USA). Essas foram as duas primeiras cirurgias utilizando esse sistema, no Brasil, gravadas no Hospital de Olhos do Paraná, Curitiba, PR e no Centro Brasileiro de Visão, Brasília, DF. O sistema 27 G é mais fino e delicado que qualquer outro, realizando incisões de apenas 0.4mm. Anteriormente, o sistema mais fino era o 25 G, com incisões de 0.55mm. Incisões menores induzem menos processo inflamatório, não precisam sutura e possibilitam recuperação mais rápida dos pacientes operados. O primeiro caso que mostramos é de uma hemorragia vítrea por retinopatia diabética proliferativa e que foi, inteiramente, operada com o novo sistema de 27 G. Ao contrário do que se imagina, mesmo com instrumentos com abertura de menor diâmetro é possível remover adequadamente opacidades vítreas densas. Para tal, basta seguirmos a lei de Poiseuille que prevê que a velocidade de fluxo de um fluido em um sistema varia diretamente com a pressão que se exerce para a retirada do mesmo e inversamente com a viscosidade do material. Os novos sistemas 27 G possuem alto nível pressórico de aspiração atingindo até 600 mmHg e a velocidade do corte vai até 7500 cortes por minuto, ou seja, se fizermos a vitrectomia utilizando esses parâmetros poderemos ter uma velocidade de fluxo semelhante aos aparelhos de maior diâmetro como o 25 ou 23 G. É a velocidade de corte sobre o vítreo que permite que, mesmo denso, ele possa ser retirado rapidamente. Observem que a cirurgia está em tempo real e toda hemorragia é aspirada em um ritmo constante e similar aos outros equipamentos anteriormente usados. Apesar de mais delicado, o sistema 27 G permite a vitrectomia da periferia sem dobrar a ponteira do equipamento. O cirurgião experiente não terá qualquer dificuldade em realizar tal procedimento. Além da ponteira de vitrectomia ser mais fina, o sistema 27 G vem acompanhado de todos os acessórios com o mesmo diâmetro, como o laser que é realizado ao final deste procedimento. No segundo caso, mostramos a cirurgia de um paciente com buraco macular. Com a alta pressão de vácuo exercida sobre o vítreo, é retirada a membrana hialoide posterior de maneira fácil e segura. Uma vez retirada a hialoide posterior, a membrana limitante interna é corada com azul brilhante para ser removida com o auxilio de fórceps apropriado. Ao final da cirurgia é realizada a troca fluido-gasosa.
The Writing of Politics and the Politics of Writing in Helen Maria Williams’ A Tour in Switzerland (1798)
Authors: Yurss Lasanta Paula 
Published: February 2017

British author and political activist Helen Maria Williams (1759-1827) dedicated the greatest part of her career to describe and analyse the French Revolution and the consequences of its aftermath. She is known for her Letters written in France (1790), an eyewitness account of her first visit to France. At the beginning of her career, Williams was praised in Britain for her sensibility poems. However, when she moved to France, and especially after the publication of A Tour Switzerland (1798), she shows her commitment to the ideas of the French Revolution while presenting her writing a source for accurate political and historical information. For this aim, she employs a series of strategies that situate herself in the position of an informed intellectual. This article focuses on A Tour in Switzerland, a work that has received less critical attention than Letters but deserves reconsideration.

Published: February 2017

Background: This systematic review and meta‐analysis aims to investigate survival rates of dental implants placed simultaneously with graft‐free maxillary sinus floor elevation (GFSFE). Factors influencing amount of vertical bone gain (VBG), protruded implant length (PIL) in sinus at follow‐up (PILf), and peri‐implant marginal bone loss (MBL) are also evaluated.Methods: Electronic and manual searches for human clinical studies on simultaneous implant placement and GFSFE using the lateral window or transcrestal approach, published in the English language from January 1976 to March 2016, were conducted. The random‐effects model and mixed‐effect meta‐regression were used to analyze weighted mean values of clinical parameters and evaluate factors that influenced amount of VBG.Results: Of 740 studies, 22 clinical studies were included in this systematic review. A total of 864 implants were placed simultaneously with GFSFE at edentulous sites having mean residual bone height of 5.7 ± 1.7 mm. Mean implant survival rate (ISR) was 97.9% ± 0.02% (range: 93.5% to 100%). Weighted mean MBL was 0.91 ± 0.11 mm, and it was significantly associated with the postoperative follow‐up period (r = 0.02; R2 = 43.75%). Weighted mean VBG was 3.8 ± 0.34 mm, and this parameter was affected significantly by surgical approach, implant length, and PIL immediately after surgery (PILi) (r = 2.82, 0.57, 0.80; R2 = 19.10%, 39.27%, 83.92%, respectively). Weighted mean PILf was 1.26 ± 0.33 mm (range: 0.3 to 2.1 mm).Conclusion: Within limitations of the present systematic review, GFSFE with simultaneous implant placement can achieve satisfactory mean ISR of 97.9% ± 0.02%.

Published: February 2017

Flavonoids are a group of polyphenolic compounds, which are widely distributed throughout the plant kingdom. Flavonoids of different classes exhibited various pharmacological and biological activities. The present study was undertaken to investigate the total flavonoids and antioxidant effect of Spilanthes acmella leaves. The ethanol extract of Spilanthes acmella leaves were prepared and performed its phytochemical screening. The total flavonoids and polyphenol were investigated to quantify the presence of polyphenol compounds. The 2,2-diphenyl-1-picryl-hydrazil stable radical (DPPH) and Superoxide scavenging radical were used to determine extract antioxidant activity. The concentrations of flavonoids polyphenol in ethanol extract of Spilanthes acmella were 72.14 QE mg/gm and 84.52 GAE mg/gm, respectively. The extract exhibited the strongest antioxidant activity, with the lowest IC50 ­value for DPPH and Superoxide scavenging. The IC50 ­value for DPPH and Superoxide scavenging were 134.11 µg/ml and 104.51 µg/ml, respectively. The strongest antioxidant activity of ethanol extract could be due to the presence of flavonoids and phenols.
Asset Evaluation Utilizing Multi-Variate Statistics Integrating Data-Mining, Completion Optimization, and Geology Focused on Multi-Bench Shale Plays
Authors: Gaurav Abhishek , Gibbon Edward J. , Roberson Timothy M. 
Published: February 2017

Abstract
The objective is to establish a robust methodology for evaluating the true economic potential of an asset integrating various sources of data, namely, geological, completions, production and leasing data retrieved from public sources.
A three segment methodology has been adopted in assessing properties for acquisition or farmout opportunities. The central idea of the work is that completions optimization is an ever-changing process. This implies the areas that were previously overlooked could potentially benefit from recent advances in completions and be more profitable. Data mining integrated with available geological information assists in identifying the key parameters that affect well performance. Once optimized for completions parameters, one can identify the real potential of an asset under consideration.
When geological factors, completions parameters, normalized production type curves, cost of drilling, completions and leasing are taken into account, we reach an even ground comparing different assets. Using this methodology, opportunities were identified in different areas that were previously overlooked. Some of the geological factors that should always be taken into account are depth (TVD), reservoir pressure, existing PVT/GOR studies, and prior knowledge of faults/fractures. The completions parameters that influence production have a wide range. However, it is reasonable to assume that length of lateral, stage spacing, type of fluid, proppant amount, rate of pumping and clusters per stage are the more important ones. The proppant amount, fluid type and rate of pumping can be inter-dependent. In areas with a significant number of horizontal wells on production, data on completions, geology and production is usually available on Public Sources, like the Texas Railroad Commission. The aggregation of data on several wells feeds into the creation of a huge data-set, in other words, big data. Once a combination of above mentioned factors is taken into account, the pattern identification process related to correlation of performance vs. parameters is quickly established. The type curve which corresponds to the optimum parameters for the particular area of interest, is then used for economic forecasting.
This paper truly integrates various factors that go into investment decision making. The advances in data visualization tools and the availability of big data from public sources assist in solidifying this robust methodology. The methodology described can be utilized by E&P companies, investment banks and private equity groups to make well informed investment decisions in the future.
Depth-of-Investigation and Volume-of-Investigation Calculated from Fracture-Injection/Falloff Test DFIT Data
Authors: Jackson Robert A. , Craig David P. 
Published: February 2017

Abstract
Unconventional reservoirs, including shale formations and many tight-gas sands, contain natural fractures, fissures, faults, and microfractures that contribute to the rock flow capacity. In most cases, core-measured permeability, and especially crushed-core permeability measurements, may not be representative of the true reservoir rock flow capacity. Evaluating the in-situ rock permeability, and simulating production, requires sampling not only the matrix, but also the fractures and fissures that contribute to the unconventional rock system permeability. A properly designed well test in an unconventional reservoir will sample a volume of reservoir rock that is representative of the whole. In other words, a well test should sample a representative elementary volume, which is the smallest volume of rock with properties characteristic of the whole.
Diagnostic fracture-injection/falloff tests (DFIT) have been routinely implemented since the late 1990s to understand leakoff mechanisms, identify fracture closure stress, estimate initial reservoir pressure, and determine permeability-thickness in unconventional reservoirs. In almost every unconventional well completed, a DFIT is the only well test that will be completed during the well lifecycle, but historically, the tests have been designed empirically based on analog formations and without considering the volume of rock investigated.
We demonstrate a new method for calculating the volume of rock investigated by a DFIT, and we show how a DFIT design can allow for sampling a representative elementary volume of the reservoir.
Enhance Microscopic Sweep Efficiency by Smart Water in Tight and Very Tight Oil Reservoirs
Authors: Kadeethum T. , Sarma H. K. , Maini B. B. 
Published: February 2017

Abstract
In the literature, improvement of oil recovery in smart water injection schemes has been shown to be mediated by wettability alteration. This process reduces residual oil saturation, which in turn affects the microscopic sweep efficiency and leads to subsequent enhancement of overall waterflood performance (Willhite, 1986). Tight and very tight oil reservoirs are often associated with high clay content and significant Cation Exchange Capacity (CEC) values (Breeuwsma et al., 1986). CEC directly influences smart waterflood behavior as it controls ion exchangeability between the solid and aqueous phases, which then regulates the double layer thickness and the wettability of the system (Nasralla and Nasr-El-Din, 2014).
This study presents the effect of lithology on CEC value. Experimental studies on smart waterflooding in tight oil cores have reported reduction of residual oil saturation by as high as five percent and improvement of microscopic sweep efficiency by six percent (Xie et al., 2015a, 2015b). The promising potential of smart water in tight and very tight oil reservoirs is similarly shown in numerical simulations, in which oil recovery is improved by three percent. Smart water may additionally retard water production by reducing water relative permeability. Furthermore, it enhances effective porosity/permeability through mineral dissolution. However, in tight oil reservoirs, pressure maintenance efficacy could be an issue. Simulation results display a significant pressure drop in the reservoir, which could lead to gas phase liberation and liquid relative permeability reduction.
Currently, few studies on smart waterflood in tight and very tight oil reservoirs exist. This work examines smart waterflood opportunities in these reservoirs from both an experimental and a numerical perspective.
Gas Selection for Huff-n-Puff EOR in Shale Oil Reservoirs Based upon Experimental and Numerical Study
Authors: Li Lei , Sheng James J. , Xu Jinze 
Published: February 2017

Abstract
Huff-n-Puff gas injection is a method originally used in heavy oil reservoir to reduce oil viscosity, increase mobility and displacement efficiency to enhance oil recovery. Now this method has been applied to enhance unconventional oil recovery in shale or tight reservoirs in recent years and proved to be effective in experiment study. N2, C1, CO2 or other rich gases are used in shale oil EOR. The purpose of this paper is to compare the EOR potential of different gas and provide a guide to choose gas based on the Wolfcamp shale oil reservoir.
The composition of crude oil from Wolfcamp was analyzed by Gas Chromatography (GC). First, the core plugs from Wolfcamp with diameters of 1.5 inches were saturated with crude oil. Then gas huff-n-puff experiments using N2, C1, and CO2 were conducted in the laboratory with the same injection pressure of 2000 psi. Based on laboratory results, a compositional model is built and used to analyze the performance of gas huff-n-puff. The EOR capacity of gas mixture (N2, C1, CO2) and some solvents such as C3-CO2 mixture, the separator gases C1 to C4 from the field production were investigated using the simulation method.
From the experiment results of the three kinds of gas injections, the oil recovery in the first two injection cycles were large. The incremental oil recovery decreased as the increase in number of injection cycles. Comparing the three kinds of gas EOR effects on Wolfcamp core samples, CO2 EOR result was the best, followed by N2 and C1. Coupling the equation of state method with GC analysis, 24 components of crude oil were achieved and then lumped into 5 pseudo components for simulation. The EOR effects of other gas mixture and solvents are investigated using the field model. The results show that the EOR effect of mixture of C1, C2 and C4 is the most favorite, followed by CO2-C3 mixture, produced gas, C1-CO2 mixture, and N2-CO2 mixture. Combined all of these results with economic factors, a comparison of gas capacity is proposed.
This investigation is focused on injection gas selection for shale oil production and helps to provide us a screening criterion to choose effective and convenient gas when conducting huff-n-puff gas injection in shale oil development. Cheaper gas with higher EOR potential will reduce the production cost and bring huge economic benefits to oil company especially in this low oil price period.
