A green-to-near-infrared photoswitch based on a blended subporphyrazine-dithienylethene system

A subporphyrazine (SubPz)-dithienylethene (DTE) photochromic device with 1o and 1c states, was developed and characterized. In this device, the DTE unit can reversibly switch the SubPz absorbance from green to near-infrared [λmax (o/c) = 527 nm/740 nm], as well as the SubPz fluorescence and singlet oxygen quantum yields. The core of this design involves using a highly tunable SubPz chromophore that shares its quasi-isolated ethene moiety with a DTE photoswitchPID2020-116490GB-I00, TED2021-131255B-C43, Comunidad de Madrid MAD2D-CM, SEV2016-068

Presence of rare potential pathogenic variants in subjects under 65 years old with very severe or fatal COVID-19

Rare variants affecting host defense against pathogens could be involved in COVID-19 severity and may help explain fatal outcomes in young and middle-aged patients. Our aim was to report the presence of rare genetic variants in certain genes, by using whole exome sequencing, in a selected group of COVID-19 patients under 65 years who required intubation or resulting in death (n = 44). To this end, different etiopathogenic mechanisms were explored using gene prioritization-based analysis in which genes involved in immune response, immunodeficiencies or blood coagulation were studied. We detected 44 different variants of interest, in 29 different patients (66%). Some of these variants were previously described as pathogenic and were located in genes mainly involved in immune response. A network analysis, including the 42 genes with candidate variants, showed three main components, consisting of 25 highly interconnected genes related to immune response and two additional networks composed by genes enriched in carbohydrate metabolism and in DNA metabolism and repair processes. In conclusion, we have detected candidate variants that may potentially influence COVID-19 outcome in our cohort of patients. Further studies are needed to confirm the ultimate role of the genetic variants described in the present study on COVID-19 severityTis work was supported by Instituto de Salud Carlos III, Spanish Ministry of Science and Innovation (COVID19 Research Call, COV20/00181) co-fnanced by European Development Regional Fund (FEDER, A way to achieve Europe) and contributions from Estrella de Levante S.A. and Colabora Mujer Association.

Age-dependent association of clonal hematopoiesis with COVID-19 mortality in patients over 60 years.

Clonal hematopoiesis, especially that of indeterminate potential (CHIP), has been associated with age-related diseases, such as those contributing to a more severe COVID-19. Four studies have attempted to associate CHIP with COVID-19 severity without conclusive findings. In the present work, we explore the association between CHIP and COVID-19 mortality. Genomic DNA extracted from peripheral blood of COVID-19 patients (n = 241 deceased, n = 239 survivors) was sequenced with the Myeloid Solutions™ panel of SOPHiA Genetics. The association between clonality and age and clonality and mortality was studied using logistic regression models adjusted for sex, ethnicity, and comorbidities. The association with mortality was performed with patients stratified into four groups of age according to the quartiles of the distribution: 60–74 years, 75–84 years, 85–91 years, and 92–101 years. Clonality was found in 38% of the cohort. The presence of CHIP variants, but not the number, significantly increased with age in the entire cohort of COVID-19 patients, as well as in the group of survivors (p < 0.001). When patients were stratified by age and the analysis adjusted, CHIP classified as pathogenic/likely pathogenic was significantly more represented in deceased patients compared with survivors in the group of 75–84 years (34.6% vs 13.7%, p = 0.020). We confirmed the well-established linear relationship between age and clonality in the cohort of COVID-19 patients and found a significant association between pathogenic/likely pathogenic CHIP and mortality in patients from 75 to 84 years that needs to be further validated.post-print1034 K

Androgen receptor polyQ alleles and COVID-19 severity in men: a replication study

Background: Ample evidence indicates a sex-related difference in severity of COVID19, with less favorable outcomes observed in men. Genetic factors have been proposed as candidates to explain this difference. The polyglutamine (polyQ) polymorphism in the androgen receptor gene has been recently described as a genetic biomarker of COVID-19 severity. Objective: To test the association between the androgen receptor polyQ polymorphism and COVID-19 severity in a large cohort of COVID-19 male patients. Materials and methods: This study included 1136 male patients infected with SARSCoV-2 as confirmed by positive PCR. Patients were retrospectively and prospectively enrolled from March to November 2020. Patients were classified according to their severity into three categories: oligosymptomatic, hospitalized and severe patients requiring ventilatory support. The number of CAG repeats (polyQ polymorphism) at the androgen receptor was obtained by PCR and patients were classified as either short (<23 repeats) or long (≥23 repeats) allele carriers. The association between polyQ alleles (short or long) and COVID-19 severity was assessed by Chi-squared (Chi2) and logistic regression analysis. Results: The mean number of polyQ CAG repeats was 22 (±3). Patients were classified as oligosymptomatic (15.5%), hospitalized (63.2%), and severe patients (21.3%) requiring substantial respiratory support. PolyQ alleles distribution did not show significant differences between severity classes in our cohort (Chi2 test p > 0.05). Similar results were observed after adjusting by known risk factors such as age, comorbidities, and ethnicity (multivariate logistic regression analysis)Instituto de Salud Carlos III (ISCIII), Spanish Ministry of Science and Innovation (COVID-19 Research Call; COV20/00181) co-financed by European Development Regional Fund (FEDER, A way to achieve Europe); Estrella de Levante (E G-N); Colabora Mujer (E G-N); Instituto de Salud Carlos III (Centro de Investigación en Red de Enfermedades Raras, CIBERer); IIS-Fundación Jiménez Díaz-UAM Chair in Genomic Medicine; Instituto de Salud Carlos III (ISCIII), Spanish Ministry of Science and Innovation (Miguel Servet Contract Number: CP17/00006 and Juan Rodes Contract Number: JR17/00020) co-financied by European Regional Development Fund (FEDER); CEGEN-PRB3-ISCIII is funded by ISCIII and ERDF, Grant Number: PT17/001

Estudio de las variables que inciden en el rendimiento académico de los estudiantes en la asignatura CENE

Con este estudio se pretende profundizar en los posibles factores que pueden influir en el rendimiento académico de los estudiantes que están cursando las asignaturas Construcción de Elementos No Estructurales I y II, en función de las calificaciones obtenidas en otras asignaturas del grado en Arquitectura Técnica impartido en la Universidad de Alicante. La población objeto de estudio corresponde a los estudiantes que han superado los tres primeros cursos del grado en Arquitectura Técnica, entre los cursos académicos 2010-11, 2011-12 y 2012-13. Se ha realizado un estudio descriptivo, inferencial y de correlación entre los resultados de las asignaturas y un posterior análisis de conglomerados que permite agrupar a los estudiantes en distintos conglomerados o clases (taxonomía). Esta clasificación ha permitido identificar en qué asignaturas destaca cada grupo de estudiantes y en cuáles tienen mayores dificultades, atendiendo a los rendimientos obtenidos en CENE I y CENE II. El conocer estos perfiles puede ayudar en la toma de decisiones para la orientación académica de los estudiantes, ayudando a identificar futuras debilidades en función de las características del alumnado

Heme oxygenase 1 and 2 common genetic variants and risk for essential tremor

Varios informes sugirieren que una función hemo oxigenasa 1 y 2 de los genes HMOX HMOX1 y 2 modifican el riesgo de desarrollar la enfermedad de Parkinson (EP). Porque el temblor esencial (ET) y PD comparten fenotipo y, probablemente, unos factores etiológicos semejantes, analizamos si tales genes están relacionados con el riesgo de desarrollar ET. Se analizó la distribución de las frecuencias genotípicas y alélicas de los HMOX1 rs2071746, HMOX1 rs2071747, HMOX2 rs2270363 y rs1051308 HMOX2 polimorfismos de nucleótido único, así como la presencia de variaciones de número de copias de estos genes en 202 sujetos con ET familiar y 747 controles sanos. Las frecuencias alélicas de rs2071746T y R1051308G ET fueron significativamente menores en los pacientes que en los controles. Ninguno de los polimorfismos estudiados influyeron en el comienzo de la enfermedad. El presente estudio sugiere una débil asociación entre HMOX1 rs2071746 y rs1051308 HMOX2 polimorfismo y el riesgo de desarrollar ET en la población española.Several reports suggested a role of heme oxygenase genes 1 and 2 (HMOX1 and HMOX2) in modifying the risk to develop Parkinson disease (PD). Because essential tremor (ET) and PD share phenotypical and, probably, etiologic factors of the similarities, we analyzed whether such genes are related with the risk to develop ET. We analyzed the distribution of allelic and genotype frequencies of the HMOX1 rs2071746, HMOX1 rs2071747, HMOX2 rs2270363, and HMOX2 rs1051308 single nucleotide polymorphisms, as well as the presence of copy number variations of these genes in 202 subjects with familial ET and 747 healthy controls. Allelic frequencies of rs2071746T and rs1051308G were significantly lower in ET patients than in controls. None of the studied polymorphisms influenced the disease onset. The present study suggests a weak association between HMOX1 rs2071746 and HMOX2 rs1051308 polymorphisms and the risk to develop ET in the Spanish population.T• Instituto de Salud Carlos III, Fondo de Investigación Sanitaria: Ayudas PI12/00241, PI12/00324 y RETICS RD12/0013/0002 • Junta de Extremadura: Ayuda GR10068 • Ministerio de Ciencia e Innovación: Ayudas SAF2006-10126 (2006–2009) y SAF2010-22329-C02-01 (2011–2013) • Parcialmente financiado Fondos FEDER – Fondo Europeo de Desarrollo RegionalpeerReviewe

Invasive Fusariosis in Nonneutropenic Patients, Spain, 2000-2015

Invasive fusariosis (IF) is associated with severe neutropenia in patients with concurrent hematologic conditions. We conducted a retrospective observational study to characterize the epidemiology of IF in 18 Spanish hospitals during 2000-2015. In that time, the frequency of IF in nonneutropenic patients increased from 0.08 cases per 100,000 admissions in 2000-2009 to 0.22 cases per 100,000 admissions in 2010-2015. Nonneutropenic IF patients often had nonhematologic conditions, such as chronic cardiac or lung disease, rheumatoid arthritis, history of solid organ transplantation, or localized fusariosis. The 90-day death rate among nonneutropenic patients (28.6%) and patients with resolved neutropenia (38.1%) was similar. However, the death rate among patients with persistent neutropenia (91.3%) was significantly higher. We used a multivariate Cox regression analysis to characterize risk factors for death: persistent neutropenia was the only risk factor for death, regardless of antifungal therapy
