<p><em>A integração vertical dos serviços em saúde surgiu como uma alternativa para a redução do custo de operação destas organizações e diminuição do nível de fragmentação dos serviços em saúde. Assim, este estudo teve por objetivo analisar o processo de integração vertical de uma operadora em saúde que atua na modalidade de autogestão em assistência médica-hospitalar, identificando ainda as potencialidades e desvantagens do processo. Para tanto, foi realizado um estudo de caso com os gestores e coordenadores da operadora, analisando as opiniões obtidas por meio das entrevistas com a literatura estudada. Os resultados destacam que a verticalização da operadora ocorreu por meio da constituição de clínica própria para atendimento dos beneficiários e da absorção dos serviços de medicina assistencial e medicina ocupacional em algumas das empresas patrocinadoras. As principais potencialidades percebidas foram a satisfação dos beneficiários, aumento da resolutividade dos problemas, otimização dos recursos da operadora, minimização de conflitos e focalização no beneficiário. Como as empresas de autogestão dividem os custos com as empresas patrocinadoras, não houve desvantagens percebidas pelos gestores. </em></p>

Published: June 2016

Objective.Capillaroscopic abnormalities are predictive of future digital ulcers (DU). Our aim was to investigate whether functional digital vascular disease (thermographically assessed) is also associated with future DU.Methods.A retrospective case note review of patients with systemic sclerosis (SSc) undergoing thermography and who were followed for up to about 3 years.Results.There were 138 patients (equal mixture of normal/abnormal thermography). Patients with abnormal thermography were more likely to develop DU (clinician-observed and/or patient-reported, OR 2.84, p = 0.021), including multiple episodes, and more likely to die (OR 5.42, p = 0.050).Conclusion.Abnormal thermography is associated with DU and disease severity in patients with SSc.

Objective.We evaluated the predictive value of these vascular biomarkers for cardiovascular disease (CVD) events in patients with rheumatoid arthritis (RA): aortic pulse wave velocity (aPWV), augmentation index (AIx), carotid intima-media thickness (cIMT), and carotid plaques (CP). They are often used as risk markers for CVD.Methods.In 2007, 138 patients with RA underwent clinical examination, laboratory tests, blood pressure testing, and vascular biomarker measurements. Occurrence of CVD events was recorded in 2013. Predictive values were assessed in Kaplan-Meier plots, log-rank, and crude and adjusted Cox proportional hazard (PH) regression analyses.Results.Baseline median age and disease duration was 59.0 years and 17.0 years, respectively, and 76.1% were women. CVD events occurred in 10 patients (7.2%) during a mean followup of 5.4 years. Compared with patients with low aPWV, AIx, cIMT, and without CP, patients with high aPWV (p < 0.001), high AIx (p = 0.04), high cIMT (p = 0.01), and CP (p < 0.005) at baseline experienced more CVD events. In crude Cox PH regression analyses, aPWV (p < 0.001), cIMT (p < 0.001), age (p = 0.01), statin (p = 0.01), and corticosteroid use (p = 0.01) were predictive of CVD events, while AIx was nonsignificant (p = 0.19). The Cox PH regression estimates for vascular biomarkers were not significantly altered when adjusting individually for demographic variables, traditional CVD risk factors, RA disease-related variables, or medication. All patients who developed CVD had CP at baseline.Conclusion.CP, aPWV, and cIMT were predictive of CVD events in this cohort of patients with RA. Future studies are warranted to examine the additive value of arterial stiffness and carotid atherosclerosis markers in CVD risk algorithms.

Published: June 2016

Introduction Hernias through the foramen of Winslow are extremely rare, accounting for 0.1% of all abdominal hernias. Delayed diagnosis is often observed, resulting in bowel strangulation and high mortality. Method We present a case of a patient with strangulated ileum herniated through the foramen of Winslow. Recent literature review was undertaken on “PubMed” as a search platform using the keywords “foramen of Winslow” and “hernia”. Case Summary A 66-year-old man presented acutely with severe epigastric pain and vomiting. An emergency computed tomography scan revealed a loop of ileum in the lesser sac. At emergency laparotomy, a herniated loop of ileum that had become strangulated at its entry to the lesser sac via the foramen of Winslow was confirmed. The loop of ileum was reduced but was nonviable, which had to be resected with a primary anastomosis. The patient's postoperative recovery was uneventful. Conclusion Herniation through the foramen of Winslow is a difficult diagnosis and must not be missed. Early cross-sectional imaging and surgical intervention are advised in order to reduce morbidity.
Evaluation of improved land use and canopy representation in BEIS v3.61 with biogenic VOC measurements in California
Authors: Bash Jesse O. , Baker Kirk R. , Beaver Melinda R. 
Published: June 2016

Abstract. Biogenic volatile organic compounds (BVOC) participate in reactions that can lead to secondarily formed ozone and particulate matter (PM) impacting air quality and climate. BVOC emissions are important inputs to chemical transport models applied on local to global scales but considerable uncertainty remains in the representation of canopy parameterizations and emission algorithms from different vegetation species. The Biogenic Emission Inventory System (BEIS) has been used to support both scientific and regulatory model assessments for ozone and PM. Here we describe a new version of BEIS which includes updated input vegetation data and canopy model formulation for estimating leaf temperature and vegetation data on estimated BVOC. The Biogenic Emission Landuse Database (BELD) was revised to incorporate land use data from the Moderate Resolution Imaging Spectroradiometer (MODIS) land product and 2006 National Land Cover Database (NLCD) land coverage. Vegetation species data are based on the US Forest Service (USFS) Forest Inventory and Analysis (FIA) version 5.1 for 2002–2013 and US Department of Agriculture (USDA) 2007 census of agriculture data. This update results in generally higher BVOC emissions throughout California compared with the previous version of BEIS. Baseline and updated BVOC emission estimates are used in Community Multiscale Air Quality (CMAQ) Model simulations with 4 km grid resolution and evaluated with measurements of isoprene and monoterpenes taken during multiple field campaigns in northern California. The updated canopy model coupled with improved land use and vegetation representation resulted in better agreement between CMAQ isoprene and monoterpene estimates compared with these observations.

Published: June 2016

The aim of this contribution was to check if adsorptive stripping differential pulse voltammetry (AdSDPV) is suitable tool for sensitive simultenous electrochemical detection of lipophilic vitamins. Retinol (vitamin A1), cholecalciferol (vitamin D3), α-tocopherol (vitamin E) and phylloquinone (vitamin K1) were selected as representatives. All electrochemical measurements were performed in two separate steps due to the lipophilic character of the analytes. In the first step, an accumulation of lipophilic vitamin on the surface of glassy carbon electrode (GCE) was done by immersing working electrode into the aqueous”‘acetonitrile solutions (50%, v/v) of each vitamin (50.0 µmol.L-1) at 400 rpm for 5 min. In the second one, differential pulse voltammetry of accumulated vitamins was performed in 0.01 mol.L-1 acetate (pH 4.5) buffer at potential step (Estep) 5 mV, potential of amplitude (Eampl) 25 mV, interval time (t) 0.1 s and scan rate (ν) 50 mV.s-1. It was observed that electrochemical behaviour of lipophilic vitamins adsorbed on surface of solid GCE in the aqueous electrolyte was very similar to those performed in organic/aqueous electrolyte in literature. Due to reversible electrochemical behaviour of vitamin K1 (phylloquinone/phyllohydroquinone redox couple), it was possible to detect all lipophilic vitamins only in one analysis. Observed values of peak potentials (Ep) were sufficiently different for their recognition which was confirmed by the analysis of real sample. The results obtained in this study showed that simultaneous determination of some lipophilic vitamins is possible requiring further optimization study. For this reason, it is necessary to understand this work as an initial step in simultaneous determination of lipophilic vitamins without application of any chromatographic technique.
Tintin as Spectacle: The Backstory of a Popular Franchise and Late Capital
Authors: Mountfort Paul 
Published: June 2016

Abstract
This article frames the Tintin franchise in terms of its evolving transmedia modes of cultural production and consumption as a story of commodification that is metonymic for key developments of the twentieth century, particularly in relation to capital and its inextricability from mass media. Drawing on elaborations of Marx’s notion of commodity fetishism, it argues developments in the early to middle decades of the twentieth century can be viewed revealingly through John Crary’s speculative explanation as to why Guy Debord chose 1927 as the precise birthdate of his Society of the Spectacle. Fredric Jameson’s analysis of late capitalism’s developmental phases through the Fifties to the Eighties supplies supplementary frames for the mid- to late twentieth century. I argue that Tintin’s progressive conscription into late capitalist spectacle reflects and reinforces these broader processes of commodification within intermeshing global culture flows, and in doing so reinscribes the cultural dominants of the twentieth century itself.
Room-temperature poling of PbTiO3/Pb(Zr,Ti)O3 sol–gel composite films by pulse discharge
Authors: Kouyama Hikaru , Kibe Taiga , Fujimoto Shota , Namihira Takao , Kobayashi Makiko 
Published: June 2016

Abstract
The PbTiO3/Pb(Zr,Ti)O3 (PT/PZT) sol–gel composite is a promising piezoelectric material because of its high piezoelectricity and temperature stability up to 360 °C. However, the poling of PT/PZT required high temperature owing to the high coercive field of PT, which made the poling of PT/PZT troublesome. In this research, conventional DC corona poling and pulse discharge at room temperature were attempted for PT/PZT samples. As a result, PT/PZT poled by pulse discharge generation at room temperature showed comparable ultrasonic responses to that poled by DC corona discharge generation at a high temperature. Therefore, room-temperature poling of PT/PZT was successfully carried out by pulse discharge, and poling time was markedly reduced from ∼15 min to 15 s.

Published: June 2016

Abstract
An elastic property of biological soft tissue is an important indicator of the tissue status. Therefore, quantitative and noninvasive methods for elasticity evaluation have been proposed. Our group previously proposed a method using acoustic radiation pressure irradiated from two directions for elastic property evaluation, in which by measuring the propagation velocity of the shear wave generated by the acoustic radiation pressure inside the object, the elastic properties of the object were successfully evaluated. In the present study, we visualized the propagation of the shear wave in a three-dimensional space by the synchronization of signals received at various probe positions. The proposed method succeeded in visualizing the shear wave propagation clearly in the three-dimensional space of 35 × 41 × 4 mm3. These results show the high potential of the proposed method to estimate the elastic properties of the object in the three-dimensional space.

AbstractKnowledge of solar wind conditions at Mars is often necessary to study the planet's magnetospheric and ionospheric dynamics. With no continuous upstream solar wind monitor at Mars, studies have used a variety of methods to measure or predict Martian solar wind conditions. In situ measurements, when available, are preferred, but can often be limited in continuity or scope, and so studies have also utilized solar wind proxies, spacecraft flybys, and Earth‐Mars alignment to provide solar wind context. Despite the importance of solar wind knowledge and the range of methods used to provide it, the use of solar wind models remains relatively unutilized. This study uses the Wang‐Sheeley‐Arge (WSA)‐ENLIL + Cone solar wind model to calculate solar wind parameters at Mars' orbital location to provide a new approach to determining solar wind conditions at Mars. Comparisons of the model results with observations by the MAVEN spacecraft indicate that the WSA‐ENLIL + Cone model can forecast solar wind conditions at Mars as accurately as it has predicted them historically at the Earth, although at Mars the model systematically mispredicts solar wind speed and density, likely a result of magnetogram calibration. Particular focus is placed on modeling the early March 2015 interplanetary coronal mass ejections (ICMEs) that interacted with Mars. Despite the complexity of the ICMEs, the model accurately predicted the speed and arrival time of the ICME‐driven interplanetary shock, although it underpredicted other solar wind parameters. These results suggest that solar wind models can be used to provide the necessary general context of the heliospheric conditions to planetary studies.
The origin of infrasonic ionosphere oscillations over tropospheric thunderstorms
Authors: Shao Xuan‐Min , Lay Erin H. 
Published: June 2016

AbstractThunderstorms have been observed to introduce infrasonic oscillations in the ionosphere, but it is not clear what processes or which parts of the thunderstorm generate the oscillations. In this paper, we present a new technique that uses an array of ground‐based GPS total electron content (TEC) measurements to locate the source of the infrasonic oscillations and compare the source locations with thunderstorm features to understand the possible source mechanisms. The location technique utilizes instantaneous phase differences between pairs of GPS‐TEC measurements and an algorithm to best fit the measured and the expected phase differences for assumed source positions and other related parameters. In this preliminary study, the infrasound waves are assumed to propagate along simple geometric raypaths from the source to the measurement locations to avoid extensive computations. The located sources are compared in time and space with thunderstorm development and lightning activity. Sources are often found near the main storm cells, but they are more likely related to the downdraft process than to the updraft process. The sources are also commonly found in the convectively quiet stratiform regions behind active cells and are in good coincidence with extensive lightning discharges and inferred high‐altitude sprites discharges.

AbstractThe Grand LAgrangian Deployment (GLAD) used multiscale sampling and GPS technology to observe time series of drifter positions with initial drifter separation of O(100 m) to O(10 km), and nominal 5 min sampling, during the summer and fall of 2012 in the northern Gulf of Mexico. Histograms of the velocity field and its statistical parameters are non‐Gaussian; most are multimodal. The dominant periods for the surface velocity field are 1–2 days due to inertial oscillations, tides, and the sea breeze; 5–6 days due to wind forcing and submesoscale eddies; 9–10 days and two weeks or longer periods due to wind forcing and mesoscale variability, including the period of eddy rotation. The temporal e‐folding scales of a fitted drifter velocity autocorrelation function are bimodal with time scales, 0.25–0.50 days and 0.9–1.4 days, and are the same order as the temporal e‐folding scales of observed winds from nearby moored National Data Buoy Center stations. The Lagrangian integral time scales increase from coastal values of 8 h to offshore values of approximately 2 days with peak values of 3–4 days. The velocity variance is large,
, the surface velocity statistics are more anisotropic, and increased dispersion is observed at flow bifurcations. Horizontal diffusivity estimates are
in coastal regions with weaker flow to
in flow bifurcations, a strong jet, and during the passage of Hurricane Isaac. The Gulf of Mexico surface velocity statistics sampled by the GLAD drifters are a strong function of the feature sampled, topography, and wind forcing.
Slab mantle dehydrates beneath Kamchatka—Yet recycles water into the deep mantle
Authors: Konrad‐Schmolke Matthias , Halama Ralf , Manea Vlad C. 
Published: June 2016

AbstractThe subduction of hydrated slab mantle is the most important and yet weakly constrained factor in the quantification of the Earth's deep geologic water cycle. The most critical unknowns are the initial hydration state and the dehydration behavior of the subducted oceanic mantle. Here we present a combined thermomechanical, thermodynamic, and geochemical model of the Kamchatka subduction zone that indicates significant dehydration of subducted slab mantle beneath Kamchatka. Evidence for the subduction of hydrated oceanic mantle comes from across‐arc trends of boron concentrations and isotopic compositions in arc volcanic rocks. Our thermodynamic‐geochemical models successfully predict the complex geochemical patterns and the spatial distribution of arc volcanoes in Kamchatka assuming the subduction of hydrated oceanic mantle. Our results show that water content and dehydration behavior of the slab mantle beneath Kamchatka can be directly linked to compositional features in arc volcanic rocks. Depending on hydration depth of the slab mantle, our models yield water recycling rates between 1.1 × 103 and 7.4 × 103 Tg/Ma/km corresponding to values between 0.75 × 106 and 5.2 × 106 Tg/Ma for the entire Kamchatkan subduction zone. These values are up to one order of magnitude lower than previous estimates for Kamchatka, but clearly show that subducted hydrated slab mantle significantly contributes to the water budget in the Kamchatkan subduction zone.
Quantifying melt production and degassing rate at mid‐ocean ridges from global mantle convection models with plate motion history

Published: June 2016

AbstractThe Earth's surface volcanism exerts first‐order controls on the composition of the atmosphere and the climate. On Earth, the majority of surface volcanism occurs at mid‐ocean ridges. In this study, based on the dependence of melt fraction on temperature, pressure, and composition, we compute melt production and degassing rate at mid‐ocean ridges from three‐dimensional global mantle convection models with plate motion history as the surface velocity boundary condition. By incorporating melting in global mantle convection models, we connect deep mantle convection to surface volcanism, with deep and shallow mantle processes internally consistent. We compare two methods to compute melt production: a tracer method and an Eulerian method. Our results show that melt production at mid‐ocean ridges is mainly controlled by surface plate motion history, and that changes in plate tectonic motion, including plate reorganizations, may lead to significant deviation of melt production from the expected scaling with seafloor production rate. We also find a good correlation between melt production and degassing rate beneath mid‐ocean ridges. The calculated global melt production and CO2 degassing rate at mid‐ocean ridges varies by as much as a factor of 3 over the past 200 Myr. We show that mid‐ocean ridge melt production and degassing rate would be much larger in the Cretaceous, and reached maximum values at ∼150–120 Ma. Our results raise the possibility that warmer climate in the Cretaceous could be due in part to high magmatic productivity and correspondingly high outgassing rates at mid‐ocean ridges during that time.
