Published: August 2019

Introducción: las fracturas de cadera son una complicación frecuente y grave en las personas
ancianas. Existen múltiples factores que se asocian con las fracturas de caderas en los ancianos, entre
los que se destacan el estado nutricional y la funcionalidad de los afectados. El estado nutricional
está condicionado en parte por el proceso de envejecimiento y por los cambios físicos, mentales,
sociales y ambientales que se asocian a éste. La desnutrición es un problema de gran relevancia en
la población anciana y que puede influir en el pronóstico asociado a diversos procesos patológicos.
La presencia de alteraciones nutricionales se han relacionado directamente con el estado funcional.
Objetivo: determinar el estado funcional y nutricional previo, y su asociación en ancianos con
fractura de cadera.
Material y métodos: se estudiaron 177 ancianos con fractura de cadera del 1º enero de 2013
hasta el 31 de diciembre de 2016 que ingresaron al programa de ortogeriatría del Hospital Universitario San Ignacio en Bogotá, Colombia. A todos los pacientes se les analizó el estado funcional
y nutricional dos semanas previo al evento. Se utilizó estadística descriptiva y análisis inferencial
para pruebas de asociación con x2.
Resultados: el 45.76% eran independientes para sus actividades básicas de la vida diaria y
54.23% presentaban algún grado de deterioro funcional. El 26.55% presentaban malnutrición, el
45.76% riesgo de malnutrición y 27.68% un estado nutricional adecuado. De los pacientes con algún
grado de malnutrición (MNA

La hemorragia alveolar difusa (HAD) masiva es una complicación inusual de los pacientes con vasculitis ANCA, frecuentemente amenaza la vida y está asociada con una mortalidad de hasta el 100%. La información en la literatura acerca del tratamiento en casos refractarios y cuando el paciente se encuentra en diálisis es escasa.
Se presenta el caso de un paciente con vasculitis p-ANCA con compromiso renal y pulmonar en el escenario de síndrome pulmón-riñón, con múltiples recaídas de hemorragia alveolar a pesar de tratamiento con corticoide, azatioprina, ciclofosfamida y terapia de recambio plasmático. Se instauró manejo con anticuerpo monoclonal anti CD20 e inmunoglobulina, logrando resolución del episodio de hemorragia alveolar y permaneciendo sin actividad. Se resalta la utilidad del rituximab como estrategia terapéutica en casos refractarios
Revised Description of Dust Diffusion and a New Instability Creating Multiple Rings in Protoplanetary Disks

Published: August 2019

Abstract
Various instabilities have been proposed as a promising mechanism for accumulating dust. Moreover, some of them are expected to lead to multiple-ring structure formation and planetesimal formation in protoplanetary disks. In a turbulent gaseous disk, the growth of the instabilities and the dust accumulation are quenched by the turbulent diffusion of dust grains. The diffusion process has often been modeled by a diffusion term in the continuity equation for the dust density. The dust diffusion model, however, does not guarantee conservation of angular momentum in a disk. In this study, we first formulate equations that describe dust diffusion and also conserve the total angular momentum of a disk. Second, we perform a linear perturbation analysis on the secular gravitational instability (GI) using the equations. The results show that the secular GI is a monotonically growing mode, contrary to the result of previous analyses that found it overstable. We find that the overstability is caused by the nonconservation of the angular momentum. Third, we find a new axisymmetric instability due to the combination of dust–gas friction and turbulent gas viscosity, which we refer to as two-component viscous gravitational instability (TVGI). The most unstable wavelength of TVGI is comparable to or smaller than the gas scale height. TVGI accumulates dust grains efficiently, which indicates that TVGI is a promising mechanism for the formation of multiple-ring-like structures and planetesimals. Finally, we examine the validity of the ring formation via the secular GI and TVGI in the HL Tau disk and find both instabilities can create multiple rings whose width is about 10 au at orbital radii larger than 50 au.

Abstract
Magnetic reconnection may be the fundamental process allowing energy stored in magnetic fields to be released abruptly, with solar flares and coronal mass ejection being archetypal natural plasma examples. Magnetic reconnection is much too slow of a process to be efficient on the large scales, but accelerates once small enough scales are formed in the system. For this reason, the fractal reconnection scenario was introduced to explain explosive events in the solar atmosphere; it was based on the recursive triggering and collapse via tearing instability of a current sheet originally thinned during the rise of a filament in the solar corona. Here we compare the different fractal reconnection scenarios that have been proposed, and derive generalized scaling relations for the recursive triggering of fast, “ideal” —i.e., Lundquist number independent—tearing in collapsing current sheet configurations with arbitrary current profile shapes. An important result is that the Sweet–Parker scaling with Lundquist number, if interpreted as the aspect ratio of the singular layer in an ideally unstable sheet, is universal and does not depend on the details of the current profile in the sheet. Such a scaling, however, must not be interpreted in terms of stationary reconnection, rather it defines a step in the accelerating sequence of events of the ideal tearing mediated fractal cascade. We calculate scalings for the expected number of plasmoids for such generic profiles and realistic Lundquist numbers, showing that in ideal tearing scenarios a smaller number of plasmoids, by orders of magnitude, is generated compared to the original fractal model.
A NuSTAR and XMM-Newton Study of the Two Most Actively Star-forming Green Pea Galaxies (SDSS J0749+3337 and SDSS J0822+2241)

Abstract
We explore X-ray evidence for the presence of active galactic nuclei (AGNs) in the two most actively star-forming Green Pea galaxies (GPs), SDSS J0749+3337 and SDSS J0822+2241, which have star formation rates (SFRs) of 123 M
⊙ yr−1 and 78 M
⊙ yr−1, respectively. The GPs have red mid-infrared (MIR) spectral energy distributions and higher 22 μm luminosities than expected from a proxy of the SFR (Hα luminosity), consistent with hosting AGNs with 2–10 keV luminosities of ∼1044 erg s−1. We thus obtain and analyze the first hard (>10 keV) X-ray data observed with NuSTAR and archival XMM-Newton data below 10 keV. From the NuSTAR ≈20 ks data, however, we find no significant hard X-ray emission. By contrast, soft X-ray emission with 0.5–8 keV luminosities of ≈1042 erg s−1 is significantly detected in both targets, which can be explained only by star formation (SF). A possible reason for the lack of clear evidence is that a putative AGN torus absorbs most of the X-ray emission. Applying a smooth-density AGN torus model, we determine minimum hydrogen column densities along the equatorial plane (

) consistent with the nondetection. The results indicate

cm−2 for SDSS J0749+3337 and

cm−2 for SDSS J0822+2241. Therefore, the GPs may host such heavily obscured AGNs. Otherwise, no AGN exists and the MIR emission is ascribed to SF. Active SF in low-mass galaxies is indeed suggested to reproduce red MIR colors. This would imply that diagnostics based on MIR photometry data alone may misidentify such galaxies as AGNs.
Onset of Giant Planet Migration before 4480 Million Years Ago

Published: August 2019

Abstract
Soon after their formation, the terrestrial planets experienced intense impact bombardment by comets, leftover planetesimals from primary accretion, and asteroids. This temporal interval in solar system evolution, termed late accretion, thermally and chemically modified solid planetary surfaces and may have impeded life's emergence on the Hadean (pre-3850 Ma) Earth. The sources and tempo of bombardment, however, remain obscure. Here we present a timeline that relates variably retentive radiometric ages documented from asteroidal meteorites to new dynamical models that invoke an early episode of planetesimal-driven giant planet migration after the dispersal of the protoplanetary disk. Reconciliation of geochronological data with dynamical models shows that such giant planet migration should lead to an intense ∼30 Myr influx of comets to the entire solar system manifested in radiometric age data. The absence of wholesale crustal reset ages after ∼4450 Ma for the most resilient chronometers from Earth, Moon, Mars, 4 Vesta, and various meteorite parent bodies confines the onset of giant planet migration to ca. 4480 Ma. Waning impacts continue to strike the inner planets through a protracted monotonic decline in impactor flux, in agreement with predictions from crater chronology. New global 3D thermal analytical bombardment models derived from our revised impact mass-production functions show also that persistent niches for prebiotic chemistry leading to the emergence of life on the early Hadean Earth could endure late accretion since at least about 4400 million years ago.

Published: August 2019

Objetivo: Identificar o conhecimento dos gestores e profissionais de saúde de um município do sertão pernambucano sobre o apoio matricial em saúde mental. Métodos:Trata-se de um estudo descritivo,de abordagem qualitativa, realizado no período de outubro de 2017 a janeiro de 2018. Foram entrevistados dez profissionais da Rede de Atenção Psicossocial municipal, por meio de um roteiro semiestruturado. A análise do conteúdo das entrevistas foi desenvolvida segundo o método de análise textual discursiva. Resultados: Evidenciaram-se lacunas de conhecimento sobre matriciamento e dificuldades para reconhecer as ações de saúde mental que devem ser desenvolvidas na Atenção Primária à Saúde. A formação acadêmica deficitária de gestores e profissionais de saúde influencia negativamente o seu conhecimento conceitual e a sua habilidade de implementar ferramentas de matriciamento em saúde mental. As principais dificuldades para matriciar foram a falta de participação dos profissionais, o estigma da pessoa portadora de transtorno mental, assim como limitações no dimensionamento de recursos humanos, carga horária de trabalho e infraestrutura dos serviços de saúde. Considerações finais:As ações de educação permanente são importantes recursos de superação dessas problemáticas, potencializando a expansão das práticas matriciais.

Abstract
The infiltration and subsequent in situ subtype specification of monocytes to effector/inflammatory and repair macrophages is indispensable for tissue repair upon acute sterile injury. However, the chromatin-level mediators and regulatory events controlling this highly dynamic macrophage phenotype switch are not known. In this study, we used a murine acute muscle injury model to assess global chromatin accessibility and gene expression dynamics in infiltrating macrophages during sterile physiological inflammation and tissue regeneration. We identified a heme-binding transcriptional repressor, BACH1, as a novel regulator of this process. Bach1 knockout mice displayed impaired muscle regeneration, altered dynamics of the macrophage phenotype transition, and transcriptional deregulation of key inflammatory and repair-related genes. We also found that BACH1 directly binds to and regulates distal regulatory elements of these genes, suggesting a novel role for BACH1 in controlling a broad spectrum of the repair response genes in macrophages upon injury. Inactivation of heme oxygenase-1 (Hmox1), one of the most stringently deregulated genes in the Bach1 knockout in macrophages, impairs muscle regeneration by changing the dynamics of the macrophage phenotype switch. Collectively, our data suggest the existence of a heme–BACH1­–HMOX1 regulatory axis, that controls the phenotype and function of the infiltrating myeloid cells upon tissue damage, shaping the overall tissue repair kinetics.

An investigation of dolphin neocortex using computed tomography and magnetic resonance Imaging

Published: August 2019

The value of the conventional medical imaging applications of Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) to areas such as medical diagnosis and surgical planning are widely documented; however, less conventional uses also exist for such technology. This paper documents an example of the diverse, interdiscipl inary value of neuroradiological techniques such as CT and MRI. An assumption has been made, in the absence of data for dolphins, that the uniquely high relative neocortex volume in primates is responsible for setting them apart from all other orders of mammals, in terms of social intelligence. An investigation of dolphin brain structure was undertaken to verify or dismiss this assertion using three species ofdiffering social structure: sol itary humpback (Sousachinensis), social bottlenose (Tursiops truncatus) and gregarious common (Delphinus delphis) dolphins. CT provided good quality images for calculation of cranial volume but only permitted gross imaging of the supra- and infratentorial regions. MRI provided greater differentiation of the different brain regions, therebya"owing volumetric measurements of the neocortical region for all subjects. There was no significant difference in neocortex calculations from fresh and frozen material, suggesting that this technique may be used on rare specimens which are frozen before examination by biologists. Correlation of neocortical development with group size was significant (pO.OOl ).
Tensões Organizacionais Inerentes como Elemento Distintivo à Natureza dos Negócios Sociais

Published: August 2019

Os Negócios Sociais (NS) são como organizações lucrativas e que possuem, simultaneamente, um propósito social e, em alguns casos, ambiental. A necessidade de conciliar esses objetivos pode fazer com que os NS sofram tensões organizacionais específicas em suas atividades. Nesse sentido, a complexidade que apresenta esse campo, devido ao seu caráter aparentemente axiomático, é justamente o fator motivacional dessa pesquisa que tem por objetivo, compreender as tensões relativas aos NS. Por meio de uma revisão da literatura em NS e de achados empíricos a partir de um estudo de casos múltiplos, foi possível identificar que os NS enfrentam desafios únicos ao combinarem objetivos distintos. Os resultados desta pesquisa demonstram que as tensões que ocorrem nas quatro dimensões organizacionais identificadas nos estudos de Smith, Gonin e Besharov (2013) proporcionam um desequilíbrio permanente característico à esse tipo organizacional que o distingue de organizações provenientes de outros setores da sociedade, identificadas nesse artigo como: tensões relacionados ao desempenho, à aspectos organizacionais, ao pertencimento e à aprendizagem, as quais, de acordo com a revisão teórica e achados empíricos, são inerentes aos NS.
Evaluating the impact of model complexity on flood wave propagation and inundation extent with a hydrologic–hydrodynamic model coupling framework

Published: August 2019

Abstract. Fluvial flood events are a major threat to people and
infrastructure. Typically, flood hazard is driven by hydrologic or river
routing and floodplain flow processes. Since they are often simulated by
different models, coupling these models may be a viable way to increase the
integration of different physical drivers of simulated inundation estimates. To facilitate coupling different models and integrating across flood hazard processes, we here present GLOFRIM 2.0, a globally applicable framework for integrated hydrologic–hydrodynamic modelling. We then tested the hypothesis that smart model coupling can advance inundation modelling in the Amazon and Ganges basins. By means of GLOFRIM, we coupled the global hydrologic model PCR-GLOBWB with the hydrodynamic models CaMa-Flood and LISFLOOD-FP. Results show that replacing the kinematic wave approximation of the hydrologic model with the local inertia equation of CaMa-Flood greatly enhances accuracy of peak discharge simulations as expressed by an increase in the Nash–Sutcliffe efficiency (NSE) from 0.48 to 0.71. Flood maps obtained with LISFLOOD-FP improved representation of observed flood extent (critical success index C=0.46), compared to downscaled products of PCR-GLOBWB and CaMa-Flood (C=0.30 and C=0.25, respectively). Results confirm that model coupling can indeed be a viable way forward towards more integrated flood simulations. However, results also suggest that the accuracy of coupled models still largely depends on the model forcing. Hence, further efforts must be undertaken to improve the magnitude and timing of simulated runoff. In addition, flood risk is, particularly in delta areas, driven by coastal processes. A more holistic representation of flood processes in delta areas, for example by incorporating a tide and surge model, must therefore be a next development step of GLOFRIM, making even more physically robust estimates possible for adequate flood risk management practices.
Pragmatic improvements to seismic resilience of non-structural elements

Published: August 2019

The recent Canterbury earthquake sequence and the more recent Seddon, Lake Grassmere and Castlepoint earthquakes have raised awareness of the vulnerability of non-structural elements of buildings (e.g. ceilings, cladding, building services equipment and piping, etc.). With architectural and building services components comprising up to 70% of a building’s value, significant damage to these elements resulted in some buildings being declared economic losses, even when the structure itself was not badly damaged. Impacts on business continuity due to the damage of non-structural elements have also been identified as a major issue in recent earthquakes in New Zealand, as well as worldwide. It appears a step change is required in the seismic performance of non-structural elements in New Zealand.
This paper explores whether the current approach being used in New Zealand for non-structural contractor designed elements is appropriate in meeting society’s expectations. It contrasts the approach that has historically been taken in New Zealand, with that followed overseas.
The paper goes on to explore a pragmatic “best bang for the buck” approach to upgrading non-structural elements in existing buildings. The approach is presented through illustrated examples of issues and solutions that have been adopted. It also discusses the challenges with trying to upgrade non-structural elements within existing operational buildings including for example, congestion issues and practicalities of access.
The paper concludes with ideas on possible ways to improve the seismic performance of non-structural elements within the New Zealand environment and regulatory regimen from both design and construction perspectives.

Agent Based Modeling: het simuleren van nalevingsgedrag
Nalevingsgedrag wordt door een aantal factoren beïnvloed. Deze factoren zijn door het ministerie van Justitie samengevat in de Tafel van Elf, die zowel spontane nalevings- als handhavingsdimensies bevat. Elk individu gaat verschillend om met deze dimensies. Om overall iets te kunnen zeggen over het nalevingsgedrag van een doelgroep dienen de verschillende individuen/bedrijven en hun interacties beschreven te worden. Dit is mogelijk door gebruik te maken van Agent-Based Modeling (ABM). ABM is in het hier beschreven onderzoek toegepast in een casestudie naar correct gebruik van antibiotica door varkenshouders. Simulaties lieten zien dat een hoog nalevingsniveau bereikt kan worden door een hoge mate van acceptatie van de wetgeving, waarbij enige mate van inspectie nodig zal blijven. Verder bleek dat het gedrag van varkenshouders beïnvloed wordt door het nalevingsgedrag van varkenshouders in de omgeving. Voor zover ons bekend is dit de eerste toepassing van ABM op het gebied van naleving en toezicht.

(G)een verrassend verschil. Twee gemeentelijke ranglijsten nader bekeken
Met de Atlas voor gemeenten en Beste gemeente beschikt Nederland over twee brede ranglijsten. Omgeven met een redelijke hoeveelheid publiciteit belanden ze elk jaar in de postbakjes van colleges van B en W en beleidsadviseurs. Wie beide lijsten met elkaar vergelijkt, wacht een flinke verrassing: de top tien van de één lijkt nauwelijks op die van de ander. Verschillen de lijsten ook verder nog van elkaar? Waar komen de verschillen vandaan? En kunnen we iets zeggen over de betrouwbaarheid en bruikbaarheid? Dit zijn enkele van de vragen die in het onderstaande artikel aan de orde komen.
