Prostate cancer management challenges due to COVID-19 in countries with low-to-middle-income economies: A radiation oncology perspective
Authors: Caicedo-Martínez María , González-Motta Alejandro , Gil-Quiñones Sebastián R. , Galvis Juan Carlos 
Published: December 2020

Description: The COVID-19 pandemic poses an unprecedented challenge for urologic oncology and radiotherapy. Radiation oncology departments and international collaboration groups are sharing their management adaptations made in response to the pandemic. The present narrative review summarizes the current recommendations.
Relevance: There is a need to define which patients are candidates for safe treatment delay until the pandemic is over or controlled, to reduce exposure to the virus in the healthcare personnel and patients.
Conclusions: Telemedicine is recommended for follow-up visits. Active surveillance is the preferred treatment for patients with favorable intermediate risk. In greater risk disease, hormone therapy safely postpones radiotherapy up to 7 months. Radiosurgery is suggested in centers that have the necessary technology and previous experience. A moderately hypofractionated regimen is recommended if radiosurgery/ultra-hypofractionation is not available. Hypofractionation should be implemented if image-guided radiation therapy is already in place. Countries with low and middle-income economies face challenges in adopting the recommendations for prostate cancer management during the pandemic. Postponing treatment may result in the overwhelming of radiation oncology center capacity, after the pandemic.

Published: December 2020

Descripción del caso clínico: Masculino de 47 años que presentó lesiones cutáneas nodulares rojo-violáceas en cara, cuero cabelludo y manos, biopsia con reporte de metástasis de tumor renal. Estado general conservado, masa palpable abdominal y microhematuria. Tomografía reportó tumor renal derecho infiltrando grasa perirrenal. Se realizó nefrectomía radical derecha, reporte histopatológico tumor de células claras con 60% de componente sarcomatoide. Inició sunitinib con involución de las lesiones cutáneas, tras 2 semanas de intermitencia presentó recurrencia modificándose la dosis. Tres meses después presentó actividad metastásica cerebral, hepática y ósea evolucionando tórpidamente, falleciendo a cinco meses del diagnóstico.
Relevancia: Particularmente nuestro caso no solo presenta una forma infrecuente de metástasis de cáncer renal recidivante a pesar del tratamiento con inhibidores de la tirosincinasa, sino también diferenciación sarcomatoide, una variante muy agresiva de cáncer renal.
Implicaciones clínicas: Las metastásis cutáneas de cáncer renal presentan una incidencia aproximada de 3%, si bien no es de buen pronóstico encontrarlas, su detección oportuna es primordial en todo paciente.
Conclusiones: El carcinoma renal sarcomatoide es un tumor raro y de pronóstico sombrío, generalmente asociado a metastásis a distancia. Es necesaria la valoración cutánea completa de todo paciente diagnosticado con cáncer renal para el adecuado estadiaje y tratamiento.

Utilidad del 18-FDG-PET/CT para determinar viabilidad tumoral en manejo de masas residuales de seminoma posquimioterapia
Authors: Mamani-Flores Efraín , Hernández-Toriz Narciso , Huerta-Gómez Juan Carlos , Quintero-Becerra Joel , Ayala-Quispe Vianey Brígida 
Published: December 2020

Antecedentes: En las últimas décadas, el manejo postquimioterapia de seminoma ha evolucionado debido al uso creciente de tomografía por emisión de positrones con 18 fluoro-desoxi-D-glucosa (18-FDG-PET) este método solo o combinado con la tomografía computarizada (CT) se ha propuesto como herramienta no invasiva para evaluar la extensión de la enfermedad. El objetivo fue conocer su utilidad para determinar viabilidad tumoral en el manejo de masas residuales retroperitoneales de seminoma postquimioterapia.
Material y Métodos: Estudio retrospectivo monocéntrico, se revisaron expedientes clínicos de 53 pacientes durante 2013-2018. Se definió respuesta a tratamiento mediante criterios de Recist 1.1 por CT y viabilidad tumoral mediante Suv Max por 18-FDG-PET/CT. Según resultado se dividió en grupos: vigilancia (grupo 1), cirugía de rescate (grupo 2), radioterapia (grupo 3) y quimioterapia (grupo 4). Se realizo estadística descriptiva con programa SPSS v24. Se uso curva ROC para definir punto de corte, sensibilidad (S) y especificidad (E).
Resultados: Al analizar, sin discriminar por grupos, se encontró una curva ROC con punto de corte de 3.150, S 50% y E 60%, valores que no son discriminativos ni útiles para definir viabilidad tumoral. Al analizar el grupo de vigilancia y cirugía de rescate se obtuvieron S 80% y E 82%. Al comparar con los grupos 3 y 4 tuvieron un punto de corte de 3.150 y 2.350 respectivamente.
Conclusiones: Primer estudio realizado en el país, el 18 FDG-PET/CT demostró una utilidad muy pobre para discriminar viabilidad tumoral en masas residuales seminomatosas postquimioterapia, mejorando discretamente los resultados para los grupos de vigilancia y cirugía de rescate.
Drainage of organic soils and GHG emissions: validation with country data
Authors: Conchedda Giulia , Tubiello Francesco N. 
Published: December 2020

Abstract. Drainage of large areas with organic soils was conducted over the
past century to free up land for agriculture. A significant acceleration of
such trends was observed in recent decades in Southeast Asia, largely
driven by drainage of tropical peatlands, an important category of organic
soils, for cultivation of oil palm. This work presents the methods and main
results of a new methodology developed for FAOSTAT, whereby the overlay of
dynamic maps of land cover and the use of information about histosols allows
the production of a global annual dataset of drained area and emissions over
a time series, covering the period 1990–2019. This is an improvement over
the existing FAO approach, which had produced only a static map of drained
organic soils for the year 2000. Results indicate that drained area and
emissions increased by 13 % globally since 1990, reaching 24 million hectares in 2019 of drained organic soils, with world total emissions of 830 Mt of carbon dioxide (CO2) equivalent. Of these totals, the
largest contribution was from the drainage of tropical peatlands in
Southeast Asia, generating nearly half of global emissions. Results were
validated against national data reported by countries to the UN Climate
Convention and against the well-established literature. Overall, the validation
yielded a good agreement with these sources. FAOSTAT estimates explained
about 60 % of the variability in official country-reported data. The
predicted emissions were virtually identical – with over 90 % of
explained variability – to official data from Indonesia, currently the top
emitting country by drained organic soils. Also, calculated emissions
factors for oil palm plantations in Indonesia and Malaysia were in the same
range and very close to emissions factors derived from detailed field
measurements. This validation suggests that the FAO estimates may be a
useful and sound reference in support of countries reporting needs. Data are
made available through open access via the Zenodo portal (Tubiello and Conchedda,
2020) with the following DOI: https://doi.org/10.5281/zenodo.3942370.
Laboratory study of non-linear wave–wave interactions of extreme focused waves in the nearshore zone
Authors: Abroug Iskander , Abcha Nizar , Jarno Armelle , Marin François 
Published: December 2020

Abstract. Extreme waves play a crucial role in marine inundation hazards and coastal erosion. Prediction of non-linear wave–wave interactions is crucial in assessing the propagation of shallow water extreme waves in coastal regions. In this article, we experimentally study non-linear wave–wave interactions of large-amplitude focused wave groups propagating in a two-dimensional wave flume over a mild slope (β=1:25). The influence of the frequency spectrum and the steepness on the non-linear interactions of focused waves are examined. The generated wave trains correspond to Pierson–Moskowitz and JONSWAP (γ=3.3 or γ=7) spectra. Subsequently, we experimentally approach this problem by the use of a bispectral analysis applied on short time series, via the wavelet-based bicoherence parameter, which identifies and quantifies the phase coupling resulting from non-resonant or bound triad interactions with the peak frequency. The bispectral analysis shows that the phase coupling increases gradually and approaches 1 just prior to breaking, accordingly with the spectrum broadening and the energy increase in high-frequency components. Downstream breaking, the values of phase coupling between the peak frequency and its higher harmonics decrease drastically, and the bicoherence spectrum becomes less structured.
Increasing frequency in off-season tropical cyclones and its relation to climate variability and change
Authors: Hernández Ayala José J. , Méndez-Tejeda Rafael 
Published: December 2020

Abstract. This article analyzes the relationship between off-season
tropical cyclone (TC) frequency and climate variability and change for the
Pacific Ocean and Atlantic Ocean basins. TC track data were used to extract the
off-season storms for the 1900–2019 period. TC counts were aggregated by
decade, and the number of storms for the first 6 decades (presatellite
era) was adjusted. Mann–Kendall nonparametric tests were used to identify
trends in decadal TC counts and multiple linear regression (MLR) models were
used to test if climatic variability or climate change factors explained the
trends in off-season storms. MLR stepwise procedures were implemented to
identify the climate variability and change factors that explained most of
the variability in off-season TC frequency. A total of 713 TCs were
identified as occurring earlier or later than their peak seasons, most
during the month of May and in the West Pacific and South Pacific basins.
The East Pacific (EP), North Atlantic (NA) and West Pacific (WP) basins
exhibit significant increasing trends in decadal off-season TC frequency.
MLR results show that trends in sea surface temperature, global mean surface
temperature and cloud cover explain most of the increasing trend in decadal
off-season TC counts in the EP, NA and WP basins. Stepwise MLR results also
identified climate change variables as the dominant forces behind increasing
trends in off-season TC decadal counts, yet they also showed that climate
variability factors like El Niño–Southern Oscillation, the Atlantic
Multidecadal Oscillation and the Interdecadal Pacific Oscillation also
account for a portion of the variability.
About the formation of double-attacks fom Latin to the French : a phonological and declarative approach.
Authors: Bretos Bórnez Jesús , De Felipe Didier Tejedor 
Published: December 2020

The formation of the denominated double-attacks from Latin to the Romanic languages—and more specifically to French in the case that concerns us (i.e., TABULA > table, ARBORE > arbre, NUMERU > nombre, etc.)—is here analyzed in the frame of declarative phonology from a diachronic perspective, and has a starting point in the notion of dominion. This approach has enabled the enumeration of the strong restrictions upon the consonants that constitute the attacks, as well as the creation of a typology that accounts for their performance within the syllable in such a way that the positions of the prosodic curve reveal their importance in the formation of the double-attacks
What I Owe to Dib
Authors: Djemaï Abdelkader 
Published: December 2020

In 1963, a year after Independence, I discovered, not without pride, for the first time in college Algerian authors who were not in the curriculum of the French school I had attended. Among them, Mohammed Dib and his Grande Maison. At the age of 15, I thus crossed the threshold of this literature that would accompany me in my life as a reader and writer.
Here I would like to tell my relationship with the diverse and rich work of Mohammed Dib, my encounters with the man and my view of some of his novels and poetry collections. In this personal testimony, I would like to evoke what he was able to bring to the writers of the Independence generation.

Reinstatement of the Patagonian moss Ulota glabella Mitt. (Bryophyta, Orthotrichaceae)
Authors: Garilleti Ricardo , Albertos Belén , Draper Isabel , Calleja Juan Antonio , Lara Francisco 
Published: December 2020

In 1842, J.D. Hooker collected a number of mosses on Hermite Island (Cape Horn region). From one of those gatherings, Hooker 141, four species of Ulota have been described: U. luteola, U. fuegiana, U. glabella, and U. eremitensis. The first two species are widely accepted, whereas the identity of the latter two has been recently discussed, and the names are now synonymized under U. fuegiana, the more widely distributed species in the Tierra del Fuego archipelago. Our studies, based on recent collections of Orthotrichaceae from Patagonia, show that specimens different from those of U. fuegiana and agreeing with the protologues of both U. glabella and U. eremitensis are common in Patagonia. Comparisons with type material of all four names demonstrate that the type for U. glabella is in such bad condition that it cannot be used, and an epitype should be selected. In this paper, we comment on the whereabouts of the collection Hooker 141 and the species described from it, discuss the distinct identity of U. glabella and its relationship with U. eremitensis as well as its differentiation from other species, present a diagnostic description of U. glabella and, finally, select an epitype to fix the application of this name.

Le rôle de l’environnement dans les maladies diarrhéiques chez l’enfant : l’apport des méthodes mixtes
Authors: Rautu Iulia , Dos Santos Stéphanie , Schoumaker Bruno , Le Hesran Jean-Yves 
Published: December 2020

Malgré de nombreux progrès, les maladies diarrhéiques demeurent la principale charge de morbidité chez l’enfant en milieu urbain d’Afrique subsaharienne. Dans ce contexte, la présente étude traite du rôle que joue l’environnement immédiat (du ménage et du quartier) sur la morbidité diarrhéique chez les enfants de 2 à 10 ans vivant dans l’agglomération de Dakar, la capitale du Sénégal. La recherche a adopté une approche de méthodes mixtes et a été menée en deux étapes. La première est quantitative et la seconde, qualitative. Les résultats montrent, premièrement, que les comportements individuels en termes de santé sont souvent une fonction de l’environnement immédiat. Ils révèlent aussi que les indicateurs statistiques couramment utilisés pour mesurer l’assainissement donnent, dans certains cas, une compréhension biaisée des conditions de vie des populations concernées. Ainsi, l’étude illustre comment la triangulation des approches quantitative et qualitative permet d’obtenir une image plus fiable de ces aspects et de pallier les sources de biais inhérentes à chacune des approches. Elle avance aussi les bénéfices liés au fait de baser la construction de l’instrument quantitatif sur un volet qualitatif exploratoire, afin de mieux adapter les informations chiffrées aux conditions spécifiques de vie des individus et des ménages.
Dilemmes des médecins traitants lors du retour au travail de personnes aux prises avec un trouble mental courant : illustration par des vignettes cliniques
Authors: Boileau-Falardeau Fabienne , Turcotte Jean-Robert , Lafleur Paul-André , Corbière Marc 
Published: December 2020

Introduction Les troubles mentaux courants (TMC) sont une des causes majeures d’invalidité au travail dans le monde. Plusieurs études démontrent que plus la durée de l’arrêt de travail est longue, plus minces sont les chances que la personne avec un TMC retourne au travail. Il est donc important que l’arrêt de travail soit d’une durée adéquate pour permettre à l’individu un rétablissement durable tout en diminuant les risques de rechute. Les médecins traitants ont un rôle important à jouer dans le cadre de la reprise professionnelle des personnes avec un TMC.
Objectif Cet article a comme principal objectif de présenter des vignettes cliniques supportées par la littérature relativement à la gestion par les médecins traitants de la reprise professionnelle de leurs patients avec un TMC.
Méthodologie Issues d’expériences cliniques, 3 vignettes cliniques illustrant plusieurs dilemmes que des médecins traitants peuvent rencontrer lors de la reprise professionnelle de leurs patients avec un TMC sont présentées. Les dilemmes sont soutenus par des articles publiés entre 2000 à 2020, provenant des bases de données Medline et PsycInfo.
Résultats et discussion Les 3 vignettes portent sur les dilemmes relatifs aux thèmes suivants : 1) l’évaluation du potentiel thérapeutique des arrêts de travail ; 2) le rôle d’expert octroyé aux médecins traitants et au processus d’évaluation de la capacité à travailler ; 3) les aspects administratifs liés à cette évaluation ; 4) la relation thérapeutique médecin-patient. La littérature nous indique que ce sont des dilemmes récurrents chez les médecins traitants dans le contexte de la gestion de la reprise professionnelle à la suite d’un TMC.
Conclusion La gestion des arrêts maladie chez les travailleurs avec un TMC par les médecins traitants comporte plusieurs dilemmes. Ces dilemmes mettent en lumière, entre autres, l’importance pour les médecins traitants de travailler en collaboration avec les autres acteurs et d’obtenir leur soutien et collaboration. Ces observations nous amènent à conduire une revue plus systématique de l’expérience des médecins traitants et de leurs besoins.
El Máster en Profesorado de Música: análisis de los planes de estudio desde la perspectiva de la sociedad y economía del conocimiento
Authors: Serrano Pastor Rosa María , Zamorano Valenzuela Felipe Javier , González-Martín Cristina 
Published: December 2020

El presente artículo tiene como objetivo conocer la adecuación de la planificación que por escrito ofrecen las universidades españolas en relación a la formación del profesorado de música de Educación Secundaria a las demandas de la escuela y el aula de música en la sociedad y economía del conocimiento. Para ello, realizamos un análisis documental comparado de los planes de estudio de 26 Másteres en Profesorado que ofrecen la especialidad de música en el territorio español. Planteamos los resultados tanto de manera general, describiendo denominaciones, competencias, estructuras y créditos de los planes de estudio; como de manera específica, definiendo tipologías en las materias de los módulos específico musical y Prácticum. Concluimos que ciertos planes de estudio promueven la construcción de capacidades fundamentales para dar respuesta a la sociedad y economía del conocimiento, como la reflexividad colegiada y la interdisciplinariedad, el pensamiento creativo y el emprendimiento, la integración tecnológica y la innovación, así como la sensibilidad sobre temas sociales. Si bien no es actualmente la orientación universitaria más habitual, pues todavía los planes de estudios están centrados en la adaptación y la perpetuación de modelos eminentemente academicistas, permite ofrecer una visión positiva de apuesta hacia una formación del profesorado deseable para todos los planes docentes.
Graphene‐Based Ultralight Compartmentalized Isotropic Foams with an Extremely Low Thermal Conductivity of 5.75 mW m−1 K−1
Authors: Oh Min Jun , Lee Je Hyun , Yoo Pil J. 
Published: December 2020

AbstractThe importance of high‐performance thermal insulation materials is rapidly emerging due to energy conservation and the management of temperature‐sensitive device perspectives. Recent thermal insulation materials including complex structures have been developed either by reducing the structural connectivity to mitigate thermal transport through solid conduction or forming directionally aligned confined inner pores to suppress the internal gas convection. In this study, to create a highly efficient thermal insulating material that suppresses thermal transport in all directions, graphene‐based anisotropic closed‐cellular structures (CCS) are devised with a highly ordered assembly of hollow compartments with extremely thin walls (≈50 nm). This uniquely designed CCS made from microfluidically synthesized graphene solid bubbles exhibited a remarkably low thermal conductivity of 5.75 mW m−1 K−1 thanks to effective suppression of both solid conduction and gas conduction/convection. Therefore, the proposed strategy in this work offers a novel toolkit for implementing next‐generation high‐performance insulation materials.
