Published: November 2019

Nos últimos 30 anos a importação de azeite de oliva e o consumo no país cresceram muito. Entretanto, estudos sobre hábitos e percepção dos consumidores com relação ao produto ainda são pouco numerosos. O objetivo desse estudo é verificar hábitos de consumo, critérios de escolha e preferência dos consumidores gaúchos com relação ao azeite de oliva. A metodologia utilizada foi um survey realizado via internet. A amostra foi de 291 consumidores, que apresentou renda familiar e escolaridade mais elevadas que a média da população brasileira, sendo que 55% declarou consumir azeite de oliva diariamente. Os principais resultados apontam que preço, origem, grau de acidez e marca são os critérios mais importantes no momento de escolher o azeite de oliva; as origens preferidas são Portugal e Brasil; a maioria consumiria mais azeite de oliva se o produto fosse mais barato e se cozinhasse mais em casa; apenas 5% declarou ter bom conhecimento sobre como utilizar o produto; e as principais motivações para o consumo estão relacionadas à saúde e ao sabor. A contribuição de nosso estudo é gerar dados que contribuam para guiar ações educativas e promocionais, auxiliando, assim, no desenvolvimento dessa cadeia.
Method development for the determination of textural properties of sugar beet roots
Authors: Kleuker Gunnar , Hoffmann Christa M.
Published: November 2019

The harvest of sugar beet leads to root tip breakage and surface damage through mechanical impacts, which increase storage losses. For the determination of textural properties of sugar beet roots with a texture analyzer a reliable method description is missing. This study aimed to evaluate the impact of washing, soil tare, storage period from washing until measurement, sample distribution and number of roots on puncture and compression measurements. For this purpose, in 2017 comprehensive tests were conducted with sugar beet roots grown in a greenhouse. In a second step these tests were carried out with different Beta varieties from a field trial, and in addition, a flexural test was included. Results show that the storage period after washing and the sample distribution had an influence on the puncture and compression strength. It is suggested to wash the roots by hand before the measurement and to determine the strength no later than 48 h after washing. For reliable and comparable results a radial distribution of measurement points around the widest circumference of the root is recommended for the puncture test. The sample position of the compression test had an influence on the compressive strength and therefore, needs to be clearly defined. For the puncture and the compression test it was possible to achieve stable results with a small sample size, but with increasing heterogeneity of the plant stand a higher number of roots is required. The flexural test showed a high variability and is, therefore, not recommended for the analysis of sugar beet textural properties.
Development and current status of the sugar industry in Sudan
Authors: Ibrahim Tageldeen S. , Workneh Tilahun S.
Published: November 2019

The Sudanese sugar industry has been suffering from a decline of sugar production. The production of the six sugar mills has dropped in 9 years by 32%, from 775,000 t in 2008 to 526,000 t in 2017. At the Kenana sugar mill, which produces 50% of the country’s sugar, production declined by 25.8% in the period. Production also decreased by 24%, 50.2%, 36.1% and 42.7%, respectively, at the Guneid, Halfa, Sennar and Assalaya factories. The lower sugar production has led to the annual imports of about 599,500 t of sugar. The reasons for the decline in sugar production are discussed below.
Dynamics of superparamagnetic nanoparticles in viscous liquids in rotating magnetic fields
Authors: Usov Nikolai A , Rytov Ruslan A , Bautin Vasiliy A
Published: November 2019

The dynamics of magnetic nanoparticles in a viscous liquid in a rotating magnetic field has been studied by means of numerical simulations and analytical calculations. In the magneto-dynamics approximation three different modes of motion of the unit magnetization vector and particle director are distinguished depending on frequency and amplitude of the rotating magnetic field. The specific absorption rate of a dilute assembly of superparamagnetic nanoparticles in rotating magnetic field is calculated by solving the Landau–Lifshitz stochastic equation for the unit magnetization vector and the stochastic equation for the particle director. At elevated frequencies an optimal range of particle diameters is found where the specific absorption rate of an assembly in a rotating magnetic field has a maximum. It is shown that with an optimal choice of the particle sizes sufficiently large SAR values of the order of 400–500 W/g can be obtained in a rotating magnetic field with a frequency f = 400 kHz and a moderate magnetic field amplitude H0 = 100 Oe.

Published: November 2019

A two-step palladium-catalyzed procedure based on Suzuki–Miyaura cross coupling, followed by a double Buchwald–Hartwig reaction, allows for the synthesis of pharmaceutically relevant benzo[4,5]furo[3,2-b]indoles in moderate to very good yield. The synthesized compounds have been analyzed with regard to their inhibitory activity (IC50) of nucleotide pyrophosphatases h-NPP1 and h-NPP3. The activity lies in the nanomolar range. The results were rationalized based on docking studies.

Core Ideas

Genomic data from diverse germplasm used for application in targeted breeding germplasm.

Six SNPs identified that can characterize all haplotypes present at SD1 locus in diverse rice.

Three alleles of the SD1 gene identified in US rice germplasm including two semidwarf alleles.

Two SNPs identified and validated that differentiate the SD1 allele present in US germplasm.

KASP assays designed for both SNPs for use in high‐throughput breeding applications.

Plant height is an important target in US rice (Oryza sativa L.) breeding programs and the large effect of the sd1 semidwarf gene makes it a suitable target for marker‐assisted selection. Although the deletion underlying the semidwarf allele is known and a gel‐based DNA marker is available, this marker is not ideal for applied breeding because of throughput and cost constraints. The objectives of this study were to characterize the haplotype diversity at the SD1 locus within US rice germplasm and develop a single nucleotide polymorphism (SNP) assay for breeding applications. The International Rice Research Institute (IRRI) SNP‐Seek database was used to characterize the haplotype diversity present at the SD1 locus across a set of rice accessions and seven haplotypes were identified. The US rice germplasm was not well represented in the IRRI database, so a set of six SNPs was identified that could differentiate all detected haplotypes. These SNPs were designed into Kompetitive allele specific polymerase chain reaction (KASP) assays and screened across 359 elite US genotypes. Of the seven haplotypes, two were present within the US germplasm, one of which was the semidwarf deletion allele. A third haplotype was observed within the US medium‐grain germplasm and demonstrated to be a semidwarf allele derived from the induced mutation in the ‘Calrose76’. Two SNPs were identified that distinguish the three SD1 haplotypes present in the US germplasm. These SNPs were validated across the US germplasm and two biparental populations.
Training Population Optimization for Genomic Selection

Published: November 2019

Core Ideas

Training populations can be optimized for specific testing populations.

Optimized training populations are smaller, more related, and more predictive.

Stratified sampling with a relationship matrix weighted by marker effect is optimal.

The effectiveness of genomic selection in breeding programs depends on the phenotypic quality and depth, the prediction model, the number and type of molecular markers, and the size and composition of the training population (TR). Furthermore, population structure and diversity have a key role in the composition of the optimal training sets. Our goal was to compare strategies for optimizing the TR for specific testing populations (TE). A total of 1353 wheat (Triticum aestivum L.) and 644 rice (Oryza sativa L.) advanced lines were evaluated for grain yield in multiple environments. Several within‐TR optimization strategies were compared to identify groups of individuals with increased predictive ability. Additionally, optimization strategies to choose individuals from the TR with higher predictive ability for a specific TE were compared. There is a benefit in considering both the population structure and the relationship between the TR and the TE when designing an optimal TR for genomic selection. A weighted relationship matrix with stratified sampling is the best strategy for forward predictions of quantitative traits in populations several generations apart.
INTEGRATIONIST TRIADIC AGENDAS FOR CITY RESEARCH:CASES FROM RECENT URBAN STUDIES
Authors: Salama Ashraf M.
Published: November 2019

With more than 60% of the world population living in urban areas, cities are becoming at the centre of attention in academic institutions and government organizations. However, there appears to be a continuous fragmentation in the types of knowledge developed where issues or concerns are always addressed in isolation and many factors critical to a comprehensive understanding of cities towards creating better urban environments are oversimplified at best or ignored at worst. Therefore, the thrust of this paper is to demonstrate the thought processes involved in instigating frameworks, raising questions, and establishing objectives for responsive city research. It aims to present two triadic agendas that untangle the essential components of city research; the first is the Lefebvrian triadic conception on the production of space and the second is the triadic perspective of lifestyles theories for understanding housing developments, typologies, and choices. Contextually, while the theoretical underpinnings of these agendas are developed based on a body of knowledge generated in the context of the Western world, their conceptualisation is adapted to grasp and examine key unique particularities of selected emerging (and globalised) Arab cities in the Gulf region. Calling for the need for a trans-disciplinary thinking paradigm for city research, the two agendas adopt an integrationist approach that is amenable to understanding the urban realities of these cities.
A GREY COMBINED COMPROMISE SOLUTION (COCOSO-G) METHOD FOR SUPPLIER SELECTION IN CONSTRUCTION MANAGEMENT

Published: November 2019

This study investigates an extended version of the combined compromise solution method with grey numbers, named CoCoSo-G for short, to measure the performance of suppliers in a construction company in Madrid. Seven criteria from a relevant previous study are the basis for assessing the performance of suppliers, while ten suppliers are composing our decision matrix. To initiate the decision-making process, we invite experts to aid us in the qualitative evaluation of the suppliers using grey interval values. Two weighting methods, including the DEMATEL (Decision Making Trial and Evaluation Laboratory) and BWM (best worst method) are used to achieve the importance of supplier criteria in a combined manner. The DEMATEL method is used to realise the best and worst criteria, and the BWM is used to sort the criteria according to a linear programming formulation. The CoCoSo-G method used to release the score of each supplier and rank them. We compare the results obtained by the CoCoSo-G with those obtained by the Complex Proportional Assessment method. It is evident that offering grey values for supplier qualification, using the combined weighting tool and proposing the new CoCoSo-G approach facilitate the evaluation process while indicating trustable outcomes.
A Search for Multiplanet Systems with TESS Using a Bayesian N-body Retrieval and Machine Learning
Authors: Pearson Kyle A.
Published: November 2019

Transiting exoplanets in multiplanet systems exhibit non-Keplerian orbits as a result of the gravitational influence from companions, which can cause the times and durations of transits to vary. The amplitude and periodicity of the transit time variations are characteristic of the perturbing planet’s mass and orbit. The objects of interest from the Transiting Exoplanet Survey Satellite (TESS) are analyzed in a uniform way to search for transit timing variations (TTVs) with sectors 1–3 of data. Due to the volume of targets in the TESS candidate list, artificial intelligence is used to expedite the search for planets by vetting nontransit signals prior to characterizing the light-curve time series. The residuals of fitting a linear orbit ephemeris are used to search for TTVs. The significance of a perturbing planet is assessed by comparing the Bayesian evidence between a linear and nonlinear ephemeris, which is based on an N-body simulation. Nested sampling is used to derive posterior distributions for the N-body ephemeris and in order to expedite convergence, custom priors are designed using machine learning. A dual-input, multi-output convolutional neural network is designed to predict the parameters of a perturbing body given the known parameters and measured perturbation (O − C). There is evidence for three new multiplanet candidates (WASP-18, WASP-126, TOI 193) with nontransiting companions using the two-minute cadence observations from TESS. This approach can be used to identify stars in need of longer radial velocity and photometric follow-up than those already performed.

We present the first comprehensive look at the 0.35–5 μm transmission spectrum of the warm (∼800 K) Neptune HAT-P-11b derived from 13 individual transits observed using the Hubble and Spitzer Space Telescopes. Along with the previously published molecular absorption feature in the 1.1–1.7 μm bandpass, we detect a distinct absorption feature at 1.15 μm and a weak feature at 0.95 μm, indicating the presence of water and/or methane with a combined significance of 4.4σ. We find that this planet’s nearly flat optical transmission spectrum and attenuated near-infrared molecular absorption features are best matched by models incorporating a high-altitude cloud layer. Atmospheric retrievals using the combined 0.35–1.7 μm Hubble Space Telescope (HST) transmission spectrum yield strong constraints on atmospheric cloud-top pressure and metallicity, but we are unable to match the relatively shallow Spitzer transit depths without underpredicting the strength of the near-infrared molecular absorption bands. HAT-P-11b’s HST transmission spectrum is well matched by predictions from our microphysical cloud models. Both forward models and retrievals indicate that HAT-P-11b most likely has a relatively low atmospheric metallicity (<4.6 Z
⊙ and <86 Z
⊙ at the 2σ and 3σ levels respectively), in contrast to the expected trend based on the solar system planets. Our work also demonstrates that the wide wavelength coverage provided by the addition of the HST STIS data is critical for making these inferences.
The Role of C/O in Nitrile Astrochemistry in PDRs and Planet-forming Disks
Authors: Le Gal Romane , Brady Madison T. , Öberg Karin I. , Roueff Evelyne , Petit Franck Le
Published: November 2019

Complex nitriles, such as HC3N, and CH3CN, are observed in a wide variety of astrophysical environments, including at relatively high abundances in photon-dominated regions (PDRs) and the ultraviolet exposed atmospheres of planet-forming disks. The latter have been inferred to be oxygen-poor, suggesting that these observations may be explained by organic chemistry in C-rich environments. In this study we first explore if the PDR complex nitrile observations can be explained by gas-phase PDR chemistry alone if the elemental C/O ratio is elevated. In the case of the Horsehead PDR, we find that gas-phase chemistry with C/O ≳ 0.9 can indeed explain the observed nitrile abundances, increasing predicted abundances by several orders of magnitude compared to standard C/O assumptions. We also find that the nitrile abundances are sensitive to the cosmic-ray ionization treatment, and provide constraints on the branching ratios between CH3CN and CH3NC productions. In a fiducial disk model, an elevated C/O ratio increases the CH3CN and HC3N productions by more than an order of magnitude, bringing abundance predictions within an order of magnitude to what has been inferred from observations. The C/O ratio appears to be a key variable in predicting and interpreting complex organic molecule abundances in PDRs across a range of scales.
Probing Structure in Cold Gas at z ≲ 1 with Gravitationally Lensed Quasar Sight Lines

Published: November 2019

Absorption spectroscopy of gravitationally lensed quasars (GLQs) enables study of spatial variations in the interstellar and/or circumgalactic medium of foreground galaxies. We report observations of four GLQs, each with two images separated by 0.″8–3.″0, that show strong absorbers at redshifts 0.4 < z
abs < 1.3 in their spectra, including some at the lens redshift with impact parameters 1.5–6.9 kpc. We measure H i Lyman lines along two sight lines each in five absorbers (10 sight lines in total) using Hubble Space Telescope Space Telescope Imaging Spectrograph, and metal lines using Magellan Echellette or Sloan Digital Sky Survey. Our data have doubled the lens galaxy sample with measurements of H i column densities (N
H i
) and metal abundances along multiple sight lines. Our data, combined with the literature, show no strong correlation between absolute values of differences in N
H i
, N
Fe ii
, or [Fe/H] and the sight line separations at the absorber redshifts for separations of 0–8 kpc. The estimated abundance gradients show a tentative anticorrelation with abundances at galaxy centers. Some lens galaxies show inverted gradients, possibly suggesting central dilution by mergers or infall of metal-poor gas. [Fe/H] measurements and masses estimated from GLQ astrometry suggest the lens galaxies lie below the total mass–metallicity relation for early-type galaxies as well as measurements for quasar-galaxy pairs and gravitationally lensed galaxies at comparable redshifts. This difference may arise in part from the dust depletion of Fe. Higher resolution measurements of H and metals (especially undepleted elements) for more GLQ absorbers and accurate lens redshifts are needed to confirm these trends.
A New Space Weather Tool for Identifying Eruptive Active Regions
Authors: Pagano Paolo , Mackay Duncan H. , Yardley Stephanie L.
Published: November 2019

One of the main goals of solar physics is the timely identification of eruptive active regions. Space missions such as Solar Orbiter or future space weather forecasting missions would largely benefit from this achievement. Our aim is to produce a relatively simple technique that can provide real-time indications or predictions that an active region will produce an eruption. We expand on the theoretical work of Pagano et al. that was able to distinguish eruptive from non-eruptive active regions. From this, we introduce a new operational metric that uses a combination of observed line-of-sight magnetograms, 3D data-driven simulations, and the projection of the 3D simulations forward in time. Results show that the new metric correctly distinguishes active regions as eruptive when observable signatures of eruption have been identified and as non-eruptive when there are no observable signatures of eruption. After successfully distinguishing eruptive from non-eruptive active regions we illustrate how this metric may be used in a “real-time” operational sense were three levels of warning are categorized. These categories are: high risk (red), medium risk (amber), and low risk (green) of eruption. Through considering individual cases, we find that the separation into eruptive and non-eruptive active regions is more robust the longer the time series of observed magnetograms used to simulate the build up of magnetic stress and free magnetic energy within the active region. Finally, we conclude that this proof of concept study delivers promising results where the ability to categorize the risk of an eruption is a major achievement.
Efficient Production of Sound Waves by AGN Jets in the Intracluster Medium
Authors: Bambic Christopher J. , Reynolds Christopher S.
Published: November 2019

We investigate the interaction between active galactic nucleus (AGN) jets and the intracluster medium (ICM) of galaxy clusters. Specifically, we study the efficiency with which jets can drive sound waves into the ICM. Previous works focused on this issue model the jet–ICM interaction as a spherically symmetric explosion, finding that ≲12.5% of the blast energy is converted into sound waves, even for instantaneous energy injection. We develop a method for measuring sound wave energy in hydrodynamic simulations and measure the efficiency of sound wave driving by supersonic jets in a model ICM. Our axisymmetric fiducial simulations convert ≳25% of the jet energy into strong, long-wavelength sound waves that can propagate to large distances. Vigorous instabilities driven by the jet–ICM interaction generate small-scale sound waves that constructively interfere, forming powerful large-scale waves. By scanning a parameter space of opening angles, velocities, and densities, we study how our results depend on jet properties. High-velocity, wide-angle jets produce sound waves most efficiently, yet the acoustic efficiency never exceeds 1/3 of the jet energy—an indication that equipartition may limit the nonlinear energy conversion process. Our work argues that sound waves may compose a significant fraction of the energy budget in cluster AGN feedback and underscores the importance of properly treating compressive wave dissipation in the weakly collisional, magnetized ICM.
Anomalously Narrow Line Widths of Compact Massive Star-forming Galaxies at z ∼ 2.3: A Possible Inclination Bias in the Size–Mass Plane
Authors: Mowla Lamiya A. , Nelson Erica J. , Dokkum Pieter van , Tadaki Ken-ichi
Published: November 2019

Compact, massive star-forming galaxies at z ∼ 2.5 are thought to be building the central regions of giant elliptical galaxies today. However, a significant fraction of these objects were previously shown to have much smaller Hα line widths than expected. A possible interpretation is that Hα emission from their central regions, where the highest velocities are expected, is typically obscured by dust. Here we present Atacama Large Millimeter/submillimeter Array observations of the CO(3–2) emission line of three compact, massive galaxies with Hα line widths of FWHM(Hα) ∼ 125–260 km s−1 to test this hypothesis. Surprisingly, in all three galaxies, the CO line width is similar to the Hα line width: we find FWHM(CO) ∼ 165 km s−1 for all three galaxies whereas FWHM(CO) ∼ 450–700 km s−1 was expected from a simple virial estimator. These results show that the narrow Hα line widths of many compact massive star-forming galaxies are not due to preferential obscuration of the highest velocity gas. An alternative explanation for the narrow line widths is that the galaxies are disks that are viewed nearly face-on. We suggest that there may be an inclination bias in the size–mass plane, such that the apparent rest-frame optical sizes of face-on galaxies are smaller than those of edge-on galaxies. Although not conclusive, this hypothesis is supported by an observed anti-correlation between size and axis ratio of massive galaxies.
A new species of Gordius (Phylum Nematomorpha) from terrestrial habitats in North America
Authors: Anaya Christina , Schmidt-Rhaesa Andreas , Hanelt Ben , Bolek Matthew G.
Published: November 2019

Freshwater hairworms (class Gordiida) are members of the phylum Nematomorpha that use terrestrial arthropods as definitive hosts but reside as free-living adult worms in rivers, lakes, or streams. The genus Gordius consists of 90 described species, of which three species were described from freshwater habitats in North America. In this paper we describe a new species of Gordius from terrestrial habitats in Oklahoma, Texas, and Louisiana, United States. Oddly, each year hundreds of adult free-living worms appear after bouts of heavy rain on streets, sidewalks, and lawns during the winter season, when terrestrial arthropod hosts are not active. The new species is described based on morphological characters of adults and non-adult stages including the egg strings, eggs, larvae, and cysts. Adult males have a unique row of bristles on the ventral inner side of each tail lobe and a circular pattern of bristles on the terminal end of each lobe, which distinguishes them from all other described North American species of Gordius. The egg string, larval, and cyst morphology of this new species conform to previous descriptions of non-adult hairworm stages for the genus Gordius. However, the eggs of this new species of hairworm are unique, as they contain an outer shell separated by distinct space from a thick inner membrane. The consistent occurrence of this gordiid in terrestrial habitats, along with its distinct egg morphology, suggests that this new species of hairworm has a terrestrial life cycle.

Le tourisme apparait comme un risque supplémentaire mais aussi une opportunité de développement à condition de trouver de nouveaux équilibres qui parviendraient à concilier les différentes activités de manière harmonieuse, en préservant l’environnement, à l’image des modes de productions traditionnelles.
Using Policy to Improve Access to Care for Persons With Alzheimer's Disease
Authors: Skipper Alan W. , Zanetos Joanne
Published: November 2019

As Americans increase life expectancies, one disease that has captured federal attention is Alzheimer's disease. Annually, health care professionals see provider billing codes changing to meet regulatory guidelines. In 2017, the Centers for Medicare & Medicaid Services enacted billing code G0505 to provide health care reimbursements for care planning services for clients with Alzheimer's disease. In-depth assessments and screenings included a patient-centered approach with familial interventions. Due to lack of awareness, health care providers demonstrated <1% use of these assessments in eligible older adults. Congress has proposed a bill (H.R. 1873/S880) to promote provider awareness and education training on its key elements. By educating future health care providers on updated legislation, providers will be able to offer an interdisciplinary approach in meeting the health care needs of the aging population. Health care providers can maintain patient advocacy while creating a vision of change for enabling policies specific to identified demographic populations. [

Academic Leadership Roles and the Promotion of Research, Education, and Practices That Reframe Aging
Authors: Emami Azita
Published: November 2019

Healthy aging represents an aspect of nursing science where there is accelerating academic interest in a topic that is of great public interest. Thus, an opportunity presents to consider how best to leverage academic leadership roles to assure a forward-looking curriculum, foster relevant research, and communicate results to the public. There are many roles that academic nursing leaders can play in advancing transformational ideas such as healthy aging, including acting as incubator and resource, hub and bridge, educational futurist, and public advocate. Nursing brings to this transformational task knowledge of the need for evidence-based research to guide policy and decision making as it relates to aging, clinical experience, and an ability to convey to a non-professional audience the clinical experience and research results.

Enhancing New Students’ Perceptions of Nursing Using a Healthy People 2010 Group Project

A challenge for faculty teaching new nursing students is to broaden students’ perspectives about the nursing profession. Due to their limited exposure to and awareness of the various nursing roles, students often view nursing as simply caring for people who are ill. The same may be true for fast-track baccalaureate nursing students transitioning to nursing from other careers. Therefore, an innovative learning strategy was developed for the first nursing course, Introduction to Professional Nursing, for fast-track students. A condensed format of the course was taught during a 5-week period in the summer. [more...]

Published: November 2019

BACKGROUND AND OBJECTIVES:

To describe a new en face optical coherence tomography (OCT) imaging feature of type 2 choroidal neovascularization (CNV) and illustrate the OCT angiographic (OCTA) findings in these eyes.

PATIENTS AND METHODS:

Multimodal images of patients with type 2 CNV who displayed the typical “pitchfork” sign with cross-sectional OCT were reviewed. Corresponding en face structural OCT and OCTA images were analyzed to correlate the finding before and after anti-vascular endothelial growth factor (VEGF) therapy.

RESULTS:

Five eyes of five patients, including two females and three males with a median age of 13 years (range: 8 years to 84 years), were studied. The etiology for type 2 CNV was laser-induced maculopathy in two eyes, idiopathic in two eyes, and age-related macular degeneration in one eye. None of the eyes had evidence of inflammatory ocular disease. En face OCT displayed a characteristic wreath-like pattern of hyperreflective spikes surrounding the type 2 neovascular membrane that originated from the ellipsoid zone and extended into the outer nuclear layer. Wreath-like spikes resolved with intravitreal anti-VEGF injection with good visual outcomes and transformation of the neovascular lesion from a type 2 to type 1 morphology.

CONCLUSIONS:

Type 2 CNV associated with the pitchfork sign with cross-sectional OCT displayed a characteristic wreath-like pattern of hyperreflective spikes with en face OCT that resolved with anti-VEGF therapy. This form of type 2 neovascularization may occur in eyes with different underlying etiologies and without signs of intraocular inflammation and is not limited to pediatric patients.

Oral Mineralocorticoid-Receptor Antagonists: Choroidal Parameters Changes Using OCT in Central Serous Chorioretinopathy
Authors: Faghihi Houshang , Mohammadzadeh Vahid , Nabavi Amin , Faghihi Shahin , Kadivar Sakineh , Ghassemi Fariba
Published: November 2019

BACKGROUND AND OBJECTIVE:

To evaluate the efficacy and safety of oral eplerenone in the treatment of acute and chronic central serous chorioretinopathy (CSCR).

PATIENTS AND METHODS:

Treatment-naïve patients with acute (< 3 months) and chronic (≥ 3 months) CSCR were enrolled in this prospective, nonrandomized, interventional, comparative case series. Patients with acute CSCR were either treated with oral eplerenone (acute case group; n = 16) or observed only (acute control group; n = 8). All chronic patients (chronic group; n = 25) were treated with oral eplerenone. Eplerenone was prescribed 25 mg twice per day for 3 months. Best-corrected visual acuity (BCVA) and optical coherence tomography measures, including subretinal fluid (SRF) height, subfoveal choroidal thickness (CT), central CT, central choroidal volume (CV), and total CV, were assessed at baseline and 3-month follow-up (FU) visit.

RESULTS:

BCVA improvement and SRF reduction at 3-month FU relative to baseline were observed in all three study groups. SRF was completely resolved in 13 patients (81.2%) in the acute case group, four patients (50%) in the acute control group, and eight patients (32%) in the chronic group. The acute case group showed greater SRF decrease relative to baseline compared to the chronic group (
P
= .009), but the resolution of SRF between acute cases and an acute control group was not statistically significant (
P
= .076). Subfoveal CT, central CT, total CV, and central CV were significantly reduced at the 3-month FU compared to baseline in both affected and the fellow eyes in the acute case and chronic groups, whereas no change was observed in either eyes in the acute control group. At 3 months' FU, the mean logMAR visual acuity demonstrated no significant difference among the study groups (
P
= .08). Eplerenone was well-tolerated, and no serious side effect was detected.

CONCLUSIONS:

Oral eplerenone is a safe and effective treatment option for both acute and chronic CSCR. Resolution of SRF was more significant in acute CSR cases comparative to chronic cases.

Efficacy of Retinal Lesion Screening in Von Hippel-Lindau Patients With Widefield Color Fundus Imaging Versus Widefield FA
Authors: Golas Liliya , Skondra Dimitra , Ittiara Shaun , Bajic Nicole , Jeng-Miller Karen W. , Mukai Shizuo , Yonekawa Yoshihiro , Blair Michael P.
Published: November 2019

BACKGROUND AND OBJECTIVE:

Retinal hemangioblastoma is a retinal tumor in patients with Von Hippel-Lindau (VHL). The authors' objective was to determine whether widefield fluorescein angiography (FA) improves lesion detection.

PATIENTS AND METHODS:

Retrospective case series of VHL patients who underwent widefield fundus imaging and FA. Masked retina specialists graded fundus images as having: 1) definite retinal hemangioblastoma; 2) possible lesion; 3) no lesion. The number of lesions on FA was compared to widefield color imaging.

RESULTS:

One hundred six eyes of 55 patients were evaluated. A total of 94 lesions were identified on FA in 61.8% patients. Forty-three lesions (45.7%) were not identified on fundus images. Small lesion detection was significantly higher with FA compared to color imaging (
P
= .013).

CONCLUSIONS:

This study reports on improved detection of retinal hemangioblastomas with widefield FA compared to widefield fundus images. The authors recommend VHL monitoring guidelines to include periodic widefield FA to adequately screen for smaller lesions.

Published: November 2019

BACKGROUND AND OBJECTIVE:

Diabetic macular edema (DME) is a leading cause of vision loss worldwide. The object of this study is to compare global differences of baseline characteristics of patients undergoing initiation of anti-vascular endothelial growth factor (VEGF) therapy for DME.

PATIENTS AND METHODS:

This multicenter, cross-sectional study included diabetic patients with foveal-involving retinal edema secondary to DME as documented by fundus exam and optical coherence tomography who were undergoing initiation of intravitreal anti-VEGF drugs. Variables were collected to find possible risk factors and to create an epidemiological profile of DME patients undergoing initiation of anti-VEGF agents.

RESULTS:

Nine hundred two patients were selected. Mean age was 62.4 (±11) years, 49.7% were Caucasians, 57.6% were male, and 96% had type two diabetes with an average disease duration of 181.7 months ± 113 months. Of the patients included, 74.7% suffered from hypertension, 26.6% from cardiovascular disease, 12.1% from cerebrovascular disease, 12.8% from peripheral vascular disease, and 12.8% from renal insufficiency. Best-corrected visual acuity (BCVA) was 65 (±20) Early Treatment Diabetic Retinopathy Study letters, central subfield thickness was 364 (±162) μm, cube volume 11.1 ± 3.1 mm
3
, cube average thickness 328.8 μm ± 61 μm, and 63.9% had nonproliferative diabetic retinopathy. Comparison between U.S. versus international patients, and patients with BCVA 70 letters or less versus more than 70 letters were performed, significant differences were acknowledged, and risk factors were recognized.

CONCLUSION:

There were key differences in the epidemiologic profile between patients presenting with DME in the U.S. and internationally.

A Spiral Software Engineering Model to Inspire Innovation and Creativity of University Students
Authors: Atoum Issa
Published: November 2019

Youth, especially students in universities, have tremendous energy that could be utilized to support their universities’ visions and their societies. However, students face several problems -for reasons related to their personalities, monetary support, and mentoring. During incubation, an idea goes several steps to crystallize, develop, and then be evaluated to gain success. However, the innovation process is agile, unstable, and subject to the risk of failure. Therefore, this paper proposes a spiral software model, called iSpiral, starting from student ideas and ending with creative operational projects. The proposed model was compared with selected models over a set of innovative criteria. The proposed iSpiral model was found more general and actionable, especially over agility and control criteria. The proposed iSpiral model was applied to a series of interrelated student ideas. The proposed model switched unmanaged and risky initiatives into active-inspired projects.
Les ardoises de couverture découvertes en contexte sédimentaire : apports et limites de l’étude à travers l’exemple du château de Suscinio (Bretagne - Sarzeau)
Authors: Vincent Karine , Godet Émilie , Dubois Adrien
Published: November 2019

La fouille du château de Suscinio (Bretagne) a livré une importante quantité
d’ardoises provenant de la toiture du grand logis nord, daté du xiiie siècle. Complètement arasé au xvie siècle, ce logis ne conserve aujourd’hui
aucun indice en élévation permettant de caractériser la charpente et
la couverture. Seule la découverte de ce matériau de construction permet
de documenter la question des toitures à Suscinio. Deux contextes de découverte se détachent
particulièrement : des niveaux correspondant à un chantier de
construction, datés de la première moitié du xive siècle, puis un important remblai de
démolition du logis correspondant à l’abattement de la toiture au
début du xvie siècle. Procédant par échantillonnage,
1 710 éléments d’ardoises ont été prélevés, nettoyés, et inventoriés.
L’étude a ensuite été enrichie par un dialogue avec les sources écrites qui font état, à partir du xvie siècle, de travaux réguliers sur les
toitures.
