Future scenarios and opportunities for interventional radiology in the post COVID-19 era
ABSTRACT
Pandemic outbreak has led health systems worldwide into a rapid reorganization in response to coronavirus infections, forcing interventional radiology units to adapt. Interventional procedures have evolved in number, type and setting and have arguably been optimized as a direct consequence of this pandemic; a result that will undoubtedly lead to radical change within the specialty. This paper explores the future of interventional radiology from various perspectives, and forecasts the new opportunities that will be presented, from the adaptation of the interventional radiology staff and angiography suite, to the immunological environment, and through to digital medical education. We analyze the economic impact and the future relationship we can expect with the rest of the medical industry
Cultivando la educación agroecológica: el huerto colectivo urbano como espacio educativo
The current planetary socioecological crisis and the growing urbanization of human life are interdependent phenomena that impel education to rethink its objectives and processes. The notion of "sustainability" provides a broad framework of construction for activities in teaching, research, and outreach programs. Among the proposals aimed at promoting sustainability, agroecology stands out as a set of integrating practices and theories capable of transforming the productive, sociopolitical, economic, and cultural relations of the food system. Our objective in this article is to present the contributions of urban agroecology and to analyze its connection with education. Following this purpose, we share the experience of Huerto UV, an agroecological education project developed by students and researchers at Universidad Veracruzana, in association with inhabitants of the city of Xalapa, Veracruz.La actual crisis socioecológica planetaria y la creciente urbanización de la vida humana son fenómenos interdependientes que incitan a la educación a repensar sus objetivos y procesos. La noción de "sustentabilidad" provee un amplio marco en construcción para actividades docentes, de investigación y vinculación. Entre otras propuestas orientadas a promover la sustentabilidad, la agroecología se destaca como un conjunto de teorías y prácticas integradoras, capaz de transformar las relaciones productivas, sociopolíticas, económicas y culturales del sistema alimentario. Nuestro objetivo en este artículo es presentar las contribuciones de la agroecología urbana y analizar su conexión con la educación, compartiendo para ello la experiencia de Huerto UV, un proyecto de educación agroecológica desarrollado por estudiantes y profesores de la Universidad Veracruzana en vinculación con habitantes la ciudad de Xalapa, Veracruz, México
Effect of slaughter handling conditions and animal temperament on bovine meat quality markers = Efecto del manejo y del temperamento animal sobre indicadores de calidad de la carne bovina
The aim of this research was to study the effect of different handling conditions on physiological stress indicators and meat quality of beef cattle by studying animals with different temperaments. Forty animals classified by their temperament (calm and disturbed) were used. They were fed on pastures and finished with a mixed diet of corn grain and pasture. Biochemical indicators of animal stress were measured at slaughter (packed cell volume -PCV-, proteins, glucose, creatinine, alkaline phosphatase -APactivity,
cortisol, insulin, glycogen). Also, ultimate pH and instrumental colour were chosen as meat quality markers. Animal temperament showed a significantly increase (p<0.05) on PCV levels and a significantly (p<0.05) decrease on muscle glycogen. Besides, levels of plasma glucose and total proteins showed significant (p<0.05) differences associated to management applied. Meat quality markers (pH and colour) did not show significant differences according to handling conditions or temperament. Mean cortisol levels at the exsanguination time were significantly higher (p<0.05) than the values obtained one week prior to slaughter, which suggests an important effect of stress associated to slaughter procedures. It would be interesting to focus attention on theassessment of acute stress at abattoir, in order to improve handling protocols, and therefore to assure meat quality in Argentinean beef production systems.El objetivo del presente trabajo fue estudiar el
efecto de diferentes condiciones de manejo sobre
indicadores fisiológicos de estrés y de calidad de
carne en bovinos con temperamentos contrastantes.
Se utilizaron cuarenta animales clasificados
como calmos y excitables. Los mismos fueron
alimentados inicialmente a base de pasturas y
terminados con una dieta mixta de grano de maíz
y pasturas. Se dosaron indicadores bioquímicos
de estrés (hematocrito, proteínas plasmáticas,
glucosa, creatinina, actividad fosfatasa alcalina,
cortisol, insulina, contenido muscular de glucó-
geno). Como indicadores de calidad de carne se
midieron el pH de 24 h y color instrumental. El
temperamento animal demostró un incremento
significativo (p<0,05) en los niveles de hematocrito
y con una disminución significativa (p<0,05) del
glucógeno muscular. Los niveles de glucemia y de
proteínas totales mostraron modificaciones significativas
(p<0,05) asociadas con el manejo. El incremento (p<0,05) en los niveles plasmáticos de
cortisol durante la faena, independientemente del
tratamiento o el temperamento animal, sugiere un
importante efecto estresor por parte del proceso
de faena. Sería interesante centrar la atención en
el estudio del estrés agudo, a fin de mejorar
protocolos de manejo animal, y consecuentemente,
optimizar la calidad de la carne asociada en los
sistemas de producción de Argentina.Fil: Pighin, Darío Gabriel. Instituto Nacional de Tecnología Agropecuaria (INTA). Instituto Tecnología de Alimentos; Argentina.

Validation of Electroencephalographic Recordings Obtained with a Consumer-Grade, Single Dry Electrode, Low-Cost Device: A Comparative Study
The functional validity of the signal obtained with low-cost electroencephalography (EEG)
devices is still under debate. Here, we have conducted an in-depth comparison of the EEG-recordings
obtained with a medical-grade golden-cup electrodes ambulatory device, the SOMNOwatch +
EEG-6, vs those obtained with a consumer-grade, single dry electrode low-cost device, the NeuroSky
MindWave, one of the most a ordable devices currently available. We recorded EEG signals at Fp1
using the two di erent devices simultaneously on 21 participants who underwent two experimental
phases: a 12-minute resting state task (alternating two cycles of closed/open eyes periods), followed by
60-minute virtual-driving task. We evaluated the EEG recording quality by comparing the similarity
between the temporal data series, their spectra, their signal-to-noise ratio, the reliability of EEG
measurements (comparing the closed eyes periods), as well as their blink detection rate. We found
substantial agreement between signals: whereas, qualitatively, the NeuroSky MindWave presented
higher levels of noise and a biphasic shape of blinks, the similarity metric indicated that signals from
both recording devices were significantly correlated. While the NeuroSky MindWave was less reliable,
both devices had a similar blink detection rate. Overall, the NeuroSky MindWave is noise-limited,
but provides stable recordings even through long periods of time. Furthermore, its data would be of
adequate quality compared to that of conventional wet electrode EEG devices, except for a potential
calibration error and spectral differences at low frequencies.Spanish Department of Transportation, Madrid, Spain (Grant No.

Single versus tandem autologous stem-cell transplantation in patients with newly diagnosed multiple myeloma and high-risk cytogenetics. A retrospective, open-label study of the PETHEMA/Spanish Myeloma Group (GEM)
Tandem ASCT has been suggested as a valid approach to improve the prognosis of patients with MM and HR cytogenetic. In this observational, retrospective study, 213 patients with newly diagnosed MM and HR cytogenetic in 35 hospitals from the Spanish Myeloma Group underwent single or tandem ASCT between January 2015 and December 2019 after induction with VTD/VRD. HR cytogenetic was defined as having ≥1 of the following: del17p, t(4;14), t(14;16) or gain 1q21. More patients in the tandem group had R-ISS 3 and >1 cytogenetic abnormality at diagnosis. With a median follow-up of 31 months (range, 10–82), PFS after single ASCT was 41 months versus 48 months with tandem ASCT (p = 0.33). PFS in patients with del17p undergoing single ASCT was 41 months, while 52% of patients undergoing tandem ASCT were alive and disease free at 48 months. In conclusion, tandem ASCT partly overcomes the bad prognosis of HR cytogenetic
NeuroBoricuas: a novel approach for incorporating neuroscience education in schools of Puerto Rico
[EN] Puerto Rico is in dire need of transforming its education system to counter the current economic recession and ensure a future with talented Puerto Ricans at the forefront of scientific research and technology development. Here we present a group of neuroscientists and educators, the NeuroBoricuas, committed to revolutionize the scientific culture of Puerto Rico by incorporating neuroscience research training and inquiry-based activities in public and private schools. We carry out our vision through diverse methods, such as community outreach activities, where we promote neuroscience literacy using diverse learning activities. In parallel, we are designing a neuroscience course and textbook with educators to be implemented in schools. We also established neuroscience laboratories in K-12 schools and trained science teachers to manage such laboratories, using equipment from the company “Backyard Brains”. These laboratory experiences are integrated into the academic curriculum in high schools and the equipment is also available for students interested in designing their independent research projects. Lastly, we are expanding a network of committed scientists who partner with educators to help nurture future neuroscientists early in their academic endeavors. Here, we describe our trajectory and our approach to transform scientific education in Puerto Rico.We thank Dr. Gregory J. Quirk, Dr. Daniel Colon-Ramos and Dr. Mark Miller for their support. We thank Tim Marzullo, from Backyard Brains, for supporting NeuroBoricuas. We also thank Palabreria, Digi-Serv and Puerto Rico 4.0 for their constant support. We thank all the NeuroBoricuas that selflessly work hard for a better Puerto Rico.

Potencial de integração de energia solar térmica de concentração em processos de secagem de resíduos
CIES2020 - XVII Congresso Ibérico e XIII Congresso Ibero-americano de Energia SolarRESUMO: A consciencialização dos problemas resultantes das atividades económicas relacionadas com a gestão de resíduos nas regiões transfronteiriças da Andaluzia-Algarve-Alentejo (AAA), conduziu ao desenvolvimento do projeto SECASOL. Este projeto de cooperação visa a integração de energia solar térmica de concentração (ESTC) nos processos de secagem de lamas de depuração de águas residuais (ETAR) e de resíduos sólidos urbanos (RSU). Foi avaliada a integração da energia solar de concentração em processos de secagem, através da identificação das principais soluções técnicas e tipologias de secagem de resíduos e caracterização dos processos tecnológicos com influência nos requisitos de valorização do produto final. Através da estimativa dos valores anuais para GHI e DNI nas principais instalações de tratamento de RSU e águas residuais do Algarve e Andaluzia, utilizou-se um modelo simplificado para estimativa do potencial de utilização da energia solar em dois processos de secagem de interesse – materiais CDR de RSU e lamas de depuração de ETAR- em termos de quantidade de matéria processada por unidade de área de captação de energia solar.ABSTRACT: Awareness of the problems resulting from economic activities related to waste management in the cross-border regions of Andalusia-Algarve-Alentejo (AAA) led to the development of the SECASOL project. This AAA cooperation project pointing to the integration of concentration solar thermal (CST) in the sludge drying processes for wastewater treatment (WWT) and RDF of solid urban waste (MSW). CST integration in the drying processes was evaluated through the identification of the main technical solutions and types of waste drying and related technological processes on the requirements for by-product valorization. Acknowledgment of the annual values for GHI and DNI at the main MSW and WWT facilities in the Algarve and Andalusia region´s had led to a simplified model used to estimate the potential use of solar energy in two drying processes of interest – RDF materials from MSW and sewage sludge from WWT - in terms of the amount of processed product per unit of solar energy capture area.info:eu-repo/semantics/publishedVersio
Enhancing the First-Pass Effect in Acute Stroke: The Impact of Stent Retriever Characteristics
Introduction: Although stentrievers (SRs) have been a mainstay of mechanical thrombectomy (MT), and current guidelines recommend the use of SRs in the treatment of large vessel occlusion stroke (LVO), there is a paucity of studies in the literature comparing SRs directly against each other in terms of mechanical and functional properties. Timely access to endovascular therapy and the ability to restore intracranial flow in a safe, efficient, and efficacious manner have been critical to the success of MT. This study aimed to investigate the impact of contemporary SR characteristics, including model, brand, size, and length, on the first-pass effect (FPE) in patients with acute ischemic stroke. Methods: Consecutive patients with M1 occlusion treated with a single SR+BGC were recruited from the ROSSETTI registry. The primary outcome was the FPE that was defined as modified (mFPE) or true (tFPE) for the achievement of modified thrombolysis in cerebral infarction (mTICI) grades 2b-3 or 3 after a single device pass, respectively. We compared patients who achieved mFPE with those who achieved tFPE according to SR characteristics. Results: We included 610 patients (52.3% female and 47.7% male, mean age 75.1 +/- 13.62 years). mFPE was achieved in 357 patients (58.5%), whereas tFPE was achieved in 264 (43.3%). There was no significant association between SR characteristics and mFPE or tFPE. Specifically, the SR size did not show a statistically significant relationship with improvement in FPE. Similarly, the length of the SR did not yield significant differences in the mFPE and tFPE, even when the data were grouped. Conclusions: Our data indicate that contemporary SR-mediated thrombectomy characteristics, including model, brand, size, and length, do not significantly affect the FPE
