Rhino-orbital mucormycosis in a Mexican patient with COVID-19: Case report
Background: A variety of bacterial and fungal co-infections may be attributed to the coronavirus disease 2019 (COVID-19), particularly in people who already have a medical condition such diabetes mellitus or those who received large dosages of steroids.
Case report: We described a 52-year-old diabetic man who was receiving high doses of dexamethasone and antibiotics while receiving ambulatory care for COVID-19 pneumonia. His anterior rhinoscopy revealed a necrotic scab, and a sample confirmed Mucor spp. He underwent surgery and was given amphotericin as a result of the severity of the condition, palpebral ptosis, and right ocular palsy he was experiencing.
Conclusions: pre-existing diabetes mellitus, previous steroid and antimicrobial use, as well as SARS-CoV-2 infection are some of the risk factors associated with Mucor spp. infection. Prompt detection of mucormycosis is important in the management of these affected patients
Centro de Integración Cultural en el Distrito de Guadalupe - Provincia de Pacasmayo - La Libertad
El proyecto tesis nace de la idea de la necesidad de la población por parte de un
proyecto de Servicios Comunes; como lo indica el Reglamento Nacional de
Edificaciones, este proyecto se realiza con el propósito de satisfacer a la población
con la educación complementaria como danza, artesanía o música para incentivar
a la población juvenil a una formación. El proyecto comenzó de un marco teórico
de espacios públicos; donde el propósito es diseñar un proyecto que responda a la
necesidad y que se cumpla la teoría. Luego de tener los puntos pensado; ubicamos
el proyecto en la Provincia de Pacasmayo, Distrito de Guadalupe, para establecer
en un terreno ya definido por la municipalidad; estas cuentas con los parámetros
para poder diseñar; luego se pensó en la forma, en su composición volumétrica y
espacios. Se planteó la idea primero de las zonas, que por resultado de un
diagnostico situacional; nos dio las zonas que se necesita y ambientes que pueden
satisfacer a los usuarios, siempre pensado en la base educativa y cultural. Las
ideas principales son la que crea la forma y su composición partiendo de la cultura
Pakatnamu; una forma básica y regular con un espacio céntrico para el mejor flujo
del usuario dentro de la propuesta, la composición se basa en crear niveles con
formas dinámicas, el nivel del sótano, con el juego de desniveles para ganar mayor
espacio, luego el primer piso, con el juego también de desniveles y el patio central
permitiendo crear un ambiente que origine una buena iluminación y ventilación,
pero se debe considerar que el marco teórico es Espacio públicos, donde se
relaciona el parque La Paz con el proyecto por medio de una planta en forma de
“U”, orientada al parque, del segundo piso, se hace referencia del primero, ósea
que las zonas de trabajo de su distribución se diseñe de manera vertical, creando
espacios de doble altura y por último el tercer piso, con espacio relacionados al
segundo relacionados a través de espacio y circulaciones verticales. De la
composición volumétrica en resumen es compacta, pero con la relación de
volúmenes crea una dinámica y resuelve a su vez el aspecto de fachadas quedando
como resultado que el proyecto sea amigable al contexto y pueda satisfacer a la
población al que se va dirigida el proyecto.The thesis project stems from the idea of the need of the population by a Common
Services project; As indicated by the National Building Regulations, this project is
carried out with the purpose of satisfying the population with complementary
education such as dance, crafts or music to encourage the youth population to a
formation. The project began from a theoretical framework of public spaces; where
the purpose is to design a project that responds to the need and that the theory is
fulfilled. After having the points thought; we located the project in the Province of
Pacasmayo, District of Guadalupe, to establish in a land already defined by the
municipality; these accounts with the parameters to be able to design; Then they
thought about the shape, its volumetric composition and spaces. The idea of the
zones was first raised, which as a result of a situational diagnosis; He gave us the
areas that are needed and environments that can satisfy the users, always thinking
of the educational and cultural base. The main ideas are the one that creates the
form and its composition based on the Pakatnamu culture; A basic and regular way
with a central space for the best flow of the user within the proposal, the composition
is based on creating levels with dynamic shapes, the basement level, with the game
of unevenness to gain more space, then the first floor , with the game also of
unevenness and the central patio allowing to create an environment that originates
good lighting and ventilation, but it should be considered that the theoretical
framework is Public space, where the La Paz park is related to the project through
a plant U-shaped, oriented to the park, on the second floor, reference is made to the
first one, so that the work areas of its distribution are designed vertically, creating
double-height spaces and finally the third floor, with space related to the second
related through space and vertical circulations. The volumetric composition in
summary is compact, but with the relationship of volumes it creates a dynamic and
resolves the appearance of facades, resulting in the project being context friendly
and satisfying the population to which the project is directed.Tesi
Cuckoo Search with Lévy Flights for Weighted Bayesian Energy Functional Optimization in Global-Support Curve Data Fitting
ABSTRACT. The problem of data fitting is very important in many theoretical and applied fields. In this paper, we consider the problem of optimizing a weighted Bayesian energy functional for data fitting by using global-support approximating curves. By global-support curves we mean curves expressed as a linear combination of basis functions whose support is the whole domain of the problem, as opposed to other common approaches in CAD/CAM and computer graphics driven by piecewise functions (such as B-splines and NURBS) that provide local control of the shape of the curve. Our method applies a powerful nature-inspired metaheuristic algorithm called cuckoo search, introduced recently to solve optimization problems. A major advantage of this method is its simplicity: cuckoo search requires only two parameters, many fewer than other metaheuristic approaches, so the parameter tuning becomes a very simple task.The paper shows that this new approach can be successfully used to solve our optimization problem. To check the performance of our approach, it has been applied to five illustrative examples of different types, including open and closed 2D and 3D curves that exhibit challenging features, such as cusps and self-intersections. Our results show that the method performs pretty well, being able to solve our minimization problem in an astonishingly straightforward way.This research has been kindly supported by the Computer

Structural determinants of suicide during the global financial crisis in Spain: Integrating explanations to understand a complex public health problem
Introduction
Suicide is a complex public health problem in contemporary societies. Macroeconomic downturns derived from the economic crisis have been found to be associated with growing suicide mortality in the United States and in Europe. The present work is aimed to assess the association between the recent economic downturns and suicide patterns using interrupted time series analysis and, particularly, adjusting this relationship by indicators of social cohesion and community values that might provide additional insights on the complex explanation of suicidal trends.
Methods
We combined suicide, social and economic data extracted from the National Statistics Institute (INE), the Eurostat database, and the World Values Survey to assess the association between the socio-economic factors and trends in suicide rates. To study the association between the financial crisis and changes in suicide rates in Spain, we used interrupted time series analysis (ITSA).
Results
Our findings confirm that suicides increased after the 2011 recession, but remained moderately constant after the 2008 economic downturn. Suicides particularly increased after the 2011 recession in the 10-14, and 45-64 years old intervals between males and females, and apparently in older groups. However, during the 2008-2011 time period suicide rates decreased during working years (specifically among 40-44, 45-49, and 55-59 years old groups). Our results highlight the importance of social protection against unemployment and, to a lesser extent, social protection in disability and family, in reducing suicides, as well as the economic prosperity of the country.
Conclusion
This result corroborates that the economic crisis has possibly impacted the growing suicide rates of the most vulnerable groups, but exclusively during the period characterised by economic cuts after the 2011 recession. This study highlights the need to implement tailored policies that protect these collectives against suicide
Gene-environment interaction analysis of redox-related metals and genetic variants with plasma metabolic patterns in a general population from Spain: The Hortega Study
Background: Limited studies have evaluated the joint influence of redox-related metals and genetic variation on metabolic pathways. We analyzed the association of 11 metals with metabolic patterns, and the interacting role of candidate genetic variants, in 1145 participants from the Hortega Study, a population-based sample from Spain. Methods: Urine antimony (Sb), arsenic, barium (Ba), cadmium (Cd), chromium (Cr), cobalt (Co), molybdenum (Mo) and vanadium (V), and plasma copper (Cu), selenium (Se) and zinc (Zn) were measured by ICP-MS and AAS, respectively. We summarized 54 plasma metabolites, measured with targeted NMR, by estimating metabolic principal components (mPC). Redox-related SNPs (N = 291) were measured by oligo-ligation assay. Results: In our study, the association with metabolic principal component (mPC) 1 (reflecting non-essential and essential amino acids, including branched chain, and bacterial co-metabolism versus fatty acids and VLDL subclasses) was positive for Se and Zn, but inverse for Cu, arsenobetaine-corrected arsenic (As) and Sb. The association with mPC2 (reflecting essential amino acids, including aromatic, and bacterial co-metabolism) was inverse for Se, Zn and Cd. The association with mPC3 (reflecting LDL subclasses) was positive for Cu, Se and Zn, but inverse for Co. The association for mPC4 (reflecting HDL subclasses) was positive for Sb, but inverse for plasma Zn. These associations were mainly driven by Cu and Sb for mPC1; Se, Zn and Cd for mPC2; Co, Se and Zn for mPC3; and Zn for mPC4. The most SNP-metal interacting genes were NOX1, GSR, GCLC, AGT and REN. Co
and Zn showed the highest number of interactions with genetic variants associated to enriched endocrine, cardiovascular and neurological pathways. Conclusions: Exposures to Co, Cu, Se, Zn, As, Cd and Sb were associated with several metabolic patterns involved in chronic disease. Carriers of redox-related variants may have differential susceptibility to metabolic alterations associated to excessive exposure to metals.This work was supported by the Strategic Action for Research in Health sciences [CP12/03080, PI15/00071, PI10/0082, PI13/01848, PI14/00874, PI16/01402, PI21/00506 and PI11/00726], CIBER Fisiopatología Obesidad y Nutrición (CIBEROBN) (CIBER-02-08-2009, CB06/03 and CB12/03/30,016), the State Agency for Research (PID2019-108973RB- C21 and C22), the Valencia Government (GRUPOS 03/101; PROM- ETEO/2009/029 and ACOMP/2013/039, IDIFEDER/

Calidad del servicio deportivo: La calidad percibida en las instalaciones de La Romareda
El fútbol profesional es uno de los mayores negocios de nuestro país, que maneja cifras astronómicas. No obstante, si nos alejamos de los grandes clubes y ponemos la vista en las categorías inferiores, se puede observar que existe una amplia diferencia en los presupuestos de los equipos, lo que condiciona la calidad del servicio que ofrecen a sus aficionados. En este trabajo, se va a analizar la calidad del servicio prestado por el estadio del Real Zaragoza, La Romareda. Para ello, se han planteado una serie de objetivos específicos que ayuden a profundizar en la investigación, analizando la importancia y la calidad percibida de los distintos atributos planteados. Además, se comprobará si existen diferencias en la percepción de la calidad según distintas variables demográficas, según la frecuencia con la que los aficionados asisten al estadio o si son abonados al club o no. Para averiguar estos datos, se ha realizado un cuestionario online, mediante el cual se ha podido determinar el perfil del espectador medio de La Romareda, la importancia otorgada a cada atributo, la calidad percibida de los mismos y las diferencias existentes según las variables planteadas. De esta manera se han podido determinar unas conclusiones y recomendaciones a seguir, que faciliten la elaboración de posibles mejoras para este servicio

Principal Criteria for Evaluating the Quality, Safety and E cacy of hMSC-Based Products in Clinical Practice: Current Approaches and Challenges
Human Mesenchymal Stem Cells (hMSCs) play an important role as new therapeutic
alternatives in advanced therapies and regenerative medicine thanks to their regenerative and
immunomodulatory properties, and ability to migrate to the exact area of injury. These properties
have made hMSCs one of the more promising cellular active substances at present, particularly
in terms of the development of new and innovative hMSC-based products. Currently, numerous
clinical trials are being conducted to evaluate the therapeutic activity of hMSC-based products on
specific targets. Given the rapidly growing number of hMSC clinical trials in recent years and the
complexity of these products due to their cellular component characteristics and medicinal product
status, there is a greater need to define more stringent, specific, and harmonized requirements to
characterize the quality of the hMSCs and enhance the analysis of their safety and efficacy in final
products to be administered to patients. These requirements should be implemented throughout
the manufacturing process to guarantee the function and integrity of hMSCs and to ensure that the
hMSC-based final product consistently meets its specifications across batches. This paper describes
the principal phases involved in the design of the manufacturing process and updates the specific
technical requirements needed to address the appropriate clinical use of hMSC-based products. The
challenges and limitations to evaluating the safety, efficacy, and quality of hMSCs have been also
reviewed and discussed.This work was supported by Ministerio de Ciencia, Innovación y Universidades. Plan Estatal I+D+I,
