    The online version contains supplementary material available at https://doi.org/10.1038/s41380-023-02039-6The human brain’s resting-state functional connectivity (rsFC) provides stable trait-like measures of differences in the perceptual, cognitive, emotional, and social functioning of individuals. The rsFC of the prefrontal cortex is hypothesized to mediate a person’s rational self-government, as is also measured by personality, so we tested whether its connectivity networks account for vulnerability to psychosis and related personality configurations. Young adults were recruited as outpatients or controls from the same communities around psychiatric clinics. Healthy controls (n = 30) and clinically stable outpatients with bipolar disorder (n = 35) or schizophrenia (n = 27) were diagnosed by structured interviews, and then were assessed with standardized protocols of the Human Connectome Project. Data-driven clustering identified five groups of patients with distinct patterns of rsFC regardless of diagnosis. These groups were distinguished by rsFC networks that regulate specific biopsychosocial aspects of psychosis: sensory hypersensitivity, negative emotional balance, impaired attentional control, avolition, and social mistrust. The rsFc group differences were validated by independent measures of white matter microstructure, personality, and clinical features not used to identify the subjects. We confirmed that each connectivity group was organized by differential collaborative interactions among six prefrontal and eight other automatically-coactivated networks. The temperament and character traits of the members of these groups strongly accounted for the differences in rsFC between groups, indicating that configurations of rsFC are internal representations of personality organization. These representations involve weakly self-regulated emotional drives of fear, irrational desire, and mistrust, which predispose to psychopathology. However, stable outpatients with different diagnoses (bipolar or schizophrenic psychoses) were highly similar in rsFC and personality. This supports a diathesis-stress model in which different complex adaptive systems regulate predisposition (which is similar in stable outpatients despite diagnosis) and stress-induced clinical dysfunction (which differs by diagnosis).EU FEDER grants through the Spanish Ministry of Science and Technology PID2021-125017OB-I00, RTI2018-098983-B-I00, D43 TW011793-06A1, PID2021-125017OB-I00, RTI2018-098983-B-I00, D43 TW011793-06A1United States Department of Health & Human Services National Institutes of Health (NIH) - USA R01-MH124060Psychosis-Risk Outcomes Network U01 MH12463

    El calentamiento global observado durante varias décadas ha sido vinculado a cambios experimentados por el ciclo hidrológico en gran escala. La variabilidad en las precipitaciones ha generado inundaciones y sequías en numerosas áreas. Además el aumento de la temperatura del agua y las variaciones producidas por fenómenos naturales y externos afectan su calidad y agudizan su contaminación. El vertido de aguas sin tratamiento ha generado la acumulación de sedimentos, nutrientes, carbono orgánico disuelto, patógenos, contaminantes emergentes y sales, hasta contaminación térmica, con posibles efectos negativos sobre los ecosistemas y la salud humana, junto a la operación de los sistemas hídricos. Estos hechos han traído como consecuencia que las prácticas de gestión hídrica actuales no sean suficientemente sólidas para contrarrestar estos efectos sobre la veracidad del abastecimiento. Numerosos estudios han demostrado que tanto las plantas de purificación de agua como las depuradoras convencionales no son capaces de remover algunos contaminantes químicos, los cuales se encuentran en concentraciones muy bajas y que a largo plazo pueden causar daños en la biota acuática y la salud de las personas. Por lo tanto, las opciones de adaptación destinadas a asegurar la calidad del agua requieren estrategias integradas orientadas al suministro, tratamiento y reciclado del agua. En el presente trabajo se emplearon dos técnicas para estudiar la remoción de tres compuestos trazas emergentes representativos: carbamazepina, sildenafil y metilparabeno.Trabajo publicado en Acta Bioquímica Clínica Latinoamericana; no. 52, supl. 2, parte II, diciembre de 2018.Universidad Nacional de La Plat

    The Latin American experience of allografting patients with severe aplastic anaemia: real-world data on the impact of stem cell source and ATG administration in HLA-identical sibling transplants

    We studied 298 patients with severe aplastic anaemia (SAA) allografted in four Latin American countries. The source of cells was bone marrow (BM) in 94 patients and PBSCs in 204 patients. Engraftment failed in 8.1% of recipients with no difference between BM and PBSCs (P = 0.08). Incidence of acute GvHD (aGvHD) for BM and PBSCs was 30% vs 32% (P = 0.18), and for grades III–IV was 2.6% vs 11.6% (P = 0.01). Chronic GvHD (cGvHD) between BM and PBSCs was 37% vs 59% (P = 0.002) and extensive 5% vs 23.6% (P = 0.01). OS was 74% vs 76% for BM vs PBSCs (P = 0.95). Event-free survival was superior in patients conditioned with anti-thymocyte globulin (ATG)-based regimens compared with other regimens (79% vs 61%, P = 0.001) as excessive secondary graft failure was seen with other regimens (10% vs 26%, P = 0.005) respectively. In multivariate analysis, aGvHD II–IV (hazard ratio (HR) 2.50, confidence interval (CI) 1.1–5.6, P = 0.02) and aGvHD III–IV (HR 8.3 CI 3.4–20.2, Po0.001) proved to be independent negative predictors of survival. In conclusion, BM as a source of cells and ATG-based regimens should be standard because of higher GvHD incidence with PBSCs, although the latter combining with ATG in the conditioning regimen could be an option in selected high-risk patient

    El proyecto “Cine en compañía para prevenir enfermedades” es continuación del proyecto iniciado en 2017 (INNOVA-Docencia 18/2018, ApS-UCM 18/2019) y se encuadra en el campo de Salud Pública, higiene y prevención de enfermedad, dirigido a personas desfavorecidas o en riesgo de exclusión social. En esta edición se ha ampliado el área de conocimiento y profesores participantes, incluyendo no solo enfermedades infecciosas, como en ediciones anteriores, sino otras del ámbito de la Bioquímica y Biología Molecular. El proyecto es multidisciplinar e interfacultativo (21 tutores: profesores, colaboradores postdoctorales, doctorandos, estudiantes participantes en ediciones anteriores y técnico de laboratorio, de las Facultades de Farmacia, Biología y Medicina y del Hospital 12 de Octubre) y en él han participado 41 estudiantes de distintos Grados (Biología, Bioquímica, Ciencia y Tecnología de los Alimentos, Derecho, Farmacia, Ingeniería Electrónica) y Postgrados (Máster en Biología Sanitaria, y en Microbiología y Parasitología: Investigación y Desarrollo; Doctorado en Bioquímica y Biología Molecular) y participantes en la asignatura Transversal “Ciencia para la Sociedad”. La necesidad social detectada y atendida es la situación de algunos colectivos, por ejemplo, personas sin hogar, mujeres en exclusión, adictos a drogas, presidiarios o familias residentes en áreas no salubres, de una mayor exposición a determinadas enfermedades debido a sus condiciones de vida (enfermedades infecciosas, mentales, metabólicas derivadas de adicciones o alcoholismo), además de que encuentran escasas posibilidades de conocer cómo prevenirlas y la forma adecuada de recibir tratamiento. Adicionalmente, y no menos importante, acusan una carencia severa de compañía, atención y escucha de sus necesidades. Los estudiantes de universidad que cursan estudios en el campo de Ciencias y Ciencias de la Salud estudian estas enfermedades, por lo que pueden ayudar a estos colectivos en la mejora de prácticas higiénico-sanitarias, así como al acceso a la información para su prevención y tratamiento. Las actividades desarrolladas en el proyecto han consistido en el acompañamiento y desarrollo de una actividad lúdica mediante la proyección de películas comerciales que traten una enfermedad de interés en el colectivo a atender, seguida de coloquio para ayudar a conocer las formas adecuadas de prevención y tratamiento. Los equipos de 4-5 estudiantes (de distintas titulaciones y cursos) y dos tutores (senior y junior) han realizado varias visitas a centros sociales atendidos por Fundaciones con las que existe convenio de la UCM (centros de día para personas sin hogar, mujeres en exclusión, discapacitados o presidiarios, gestionados por Cáritas, Hogar-Sí, Diaconía, Medinacelli). Han investigado en profundidad las enfermedades que afectan y de interés del grupo atendido, seleccionado y analizado críticamente películas adecuadas, preparado materiales divulgativos (carteles, juegos) y diseñado y analizado encuestas para evaluar su actividad por parte de las personas atendidas y los coordinadores de los centros. Los resultados de las encuestas a todos los participantes (tutores, estudiantes, centros) y la recogida de opiniones y memorias de los estudiantes muestran una alta consecución de los objetivos de aprendizaje previstos, refuerzo de contenidos específicos de los estudios y, sobre todo, trabajo y adquisición de competencias transversales como trabajo en equipo, coordinación y asunción de responsabilidades, análisis crítico o expresión científica divulgativa. En cuanto a los objetivos de servicio, destaca la utilidad del proyecto en atención e información a los colectivos, la aplicación de los estudios a situaciones reales en atención a personas desfavorecidas y el valor social del proyecto

    Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

    Design and baseline characteristics of the finerenone in reducing cardiovascular mortality and morbidity in diabetic kidney disease trial

    Background: Among people with diabetes, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality and progression of their underlying kidney disease. Finerenone is a novel, nonsteroidal, selective mineralocorticoid receptor antagonist that has shown to reduce albuminuria in type 2 diabetes (T2D) patients with chronic kidney disease (CKD) while revealing only a low risk of hyperkalemia. However, the effect of finerenone on CV and renal outcomes has not yet been investigated in long-term trials. Patients and Methods: The Finerenone in Reducing CV Mortality and Morbidity in Diabetic Kidney Disease (FIGARO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important CV and renal outcomes in T2D patients with CKD. FIGARO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 6 years. FIGARO-DKD randomized 7,437 patients with an estimated glomerular filtration rate >= 25 mL/min/1.73 m(2) and albuminuria (urinary albumin-to-creatinine ratio >= 30 to <= 5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of the primary outcome (overall two-sided significance level alpha = 0.05), the composite of time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure. Conclusions: FIGARO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of CV and renal events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen.

We have uncovered largely disjoint sets of genes regulating these dissociable learning processes in different clusters of people with (1) unregulated temperament profiles (i.e., associatively conditioned habits and emotional reactivity), (2) organized character profiles (i.e., intentional self-control of emotional conflicts and goals), and (3) creative character profiles (i.e., self-aware appraisal of values and theories), respectively. However, little is known about how these temperament and character components of personality are jointly organized and develop in an integrated manner. In three large independent genome-wide association studies from Finland, Germany, and Korea, we used a data-driven machine learning method to uncover joint phenotypic networks of temperament and character and also the genetic networks with which they are associated. We found three clusters of similar numbers of people with distinct combinations of temperament and character profiles. Their associated genetic and environmental networks were largely disjoint, and differentially related to distinct forms of learning and memory. Of the 972 genes that mapped to the three phenotypic networks, 72% were unique to a single network. The findings in the Finnish discovery sample were blindly and independently replicated in samples of Germans and Koreans. We conclude that temperament and character are integrated within three disjoint networks that regulate healthy longevity and dissociable systems of learning and memory by nearly disjoint sets of genetic and environmental influences.Academy of Finland European Commission 286284 322098 134309 126925 121584 124282 129378 117787 41071 308676Social Insurance Institution of FinlandCompetitive State Research Financing of the Expert Responsibility area of Kuopio, Tampere and Turku University Hospitals X51001Juho Vainio FoundationPaavo Nurmi FoundationFinnish Foundation for Cardiovascular ResearchFinnish Foundation for Cardiovascular ResearchFinnish Cultural FoundationFinnish IT center for scienceTampere Tuberculosis FoundationEmil Aaltonen FoundationYrjo Jahnsson FoundationDiabetes Research Foundation of Finnish Diabetes AssociationEU Horizon 2020 755320Tampere University Hospital Supporting FoundationAmerican Foundation for Suicide Preventionnational Healthy Twin Family Register of KoreaAnthropedia FoundationSpanish Government TIN2012-38805 DPI201569585-RSigne and Ane Gyllenberg Foundatio

    Adsorption of Pharmaceuticals and Personal Care Products on Granular Activated Carbon

    We investigated the adsorption to granular activated carbon of two pharmaceuticals (carbamazepine and sildenafil citrate) and a personal-care product (methylparaben) in aqueous solution, characterized the carbon, and evaluated its influence on the kinetics and adsorption equilibrium of the compounds under study. We adjusted data for the analysis of equilibrium to Langmuir and Freundlich models of adsorption isotherms and described adsorption rate using pseudo first- and second-order models; that same analysis was made on the basis of the behavior of the initial rate. In addition, we analyzed the potentiality of a nonlinear adjustment for studying kinetics and equilibrium of adsorption, an approach requiring neither knowledge of equilibrium conditions nor a-priori hypothetical suppositions regarding the order of reaction. The results indicated that the nonlinear model was capable of describing adsorption kinetic behavior, in order to determine concentrations adsorbed at equilibrium, adsorption rates of the system, maximum adsorption capacity, and global rate constant. Granular carbon exhibited an adsorption capacity for carbamazepine and methylparaben of ca. 323 mg/g and for sildenafil citrate of ca. 142 mg/g, though with slow adsorption kinetics characterized by average adsorption times of at least 168 h.Fil: Delgado Espinosa, Nasly Yanid.

    Soil phenanthrene phytoremediation capacity in bacteria-assisted Spartina densiflora

    No full text
    8 páginas.- 4 figuras.- 2 tablas.- 46 referencias.-Polycyclic aromatic hydrocarbons (PAH) have become a threat for the conservation of wetlands worldwide. The halophyte Spartina densiflora has shown to be potentially useful for soil phenanthrene phytoremediation, but no studies on bacteria-assisted hydrocarbon phytoremediation have been carried out with this halophyte. In this work, three phenanthrene-degrading endophytic bacteria were isolated from S. densiflora tissues and used for plant inoculation. Bacterial bioaugmentation treatments slightly improved S. densiflora growth, photosynthetic and fluorescence parameters. But endophyte-inoculated S. densiflora showed lower soil phenanthrene dissipation rates than non-inoculated S. densiflora (30% below) or even bulk soil (23% less). Our work demonstrates that endophytic inoculation on S. densiflora under greenhouse conditions with the selected PAH-degrading strains did not significantly increase inherent phenanthrene soil dissipation capacity of the halophyte. It would therefore be advisable to provide effective follow-up of bacterial colonization, survival and metabolic activity during phenanthrene soil phytoremediation. © 2019 Elsevier Inc.This work has been supported by Ministerio de Economía y Competitividad ( CGL2016-75550-R , AEI/FEDER, UE).
