Design the efficiency color: Luminescent Solar Concentrators and user acceptance

Experiments were carried out with different semitransparent and colorless luminophores, so that passive energy facades of urban buildings capture effective energy through their glass. Inorganic dyes are used with rare earth elements such as Eu3 + and Nd3 + / Yb3 + lanthanide pair, to move solar spectrum towards nir wavelength range, which is the near infrared (nir) spectral region from the end of the highest visible lengths (around 780 nm) up to 3000 nm (13000 cm-1 to 3300 cm-1 ), combined with nanostructured silica particles to increase the luminescent quantum yields and brightness. User acceptance study based on emotions, considers the acceptance degree regarding presence of color in glass. Experimental results demonstrate optical power efficiency, higher with inorganic dyes (2.2%) than lanthanides (1.3%) for samples of crystals with Luminescent Solar Concentrators (csls) of 3.5 x 3.5 cm2 tinted and fully transparent, with optical transmittance ≈ 90%. Question about the presence of color in glass and its relationship with energy efficiency is solved

Treatment and rehabilitation costs of patients with injuries caused by traffic accidents in the world

ABSTRACT: To know the direct (dc) and indirect costs (ic) generated by the treatment of patients with moderate or severe injuries caused by traffic accidents (ta) in the world. Methodology: a systematic review of studies assessing the costs of treating victims of traffic accidents older than 16 between 2008 and 2013 was conducted using the PubMed, Embase, Centre for Reviews and Dissemination, Journal Storage and Scielo databases. The quality of the studies was assessed using criteria from Drummond and col, as well as the "Consolidated Health Economic Evaluation Reporting Standards statement (cheers)" and other mechanisms defined by the authors. DCs and ICs were assessed. The burden of disease (bd) was obtained with the disability-adjusted life year (daly), and the quality-adjusted life-year (qaly). The costs generated by disability / rehabilitation and traumatic brain injury (tbi) were analyzed. The monetary costs were expressed in 2010 us dollars (usd) adjusted for inflation. Results: 14 studies were analyzed, 6 of which had a good quality. We found studies with up to 567.000 patients and a duration of 10 years. Direct costs were up to usd 48.082 and indirect costs up to usd 29.706 per patient; the direct costs were exceeded by the indirect costs. The burden of disease showed high variability. In one study, 60% of the patients with severe tbi and 20% with moderate tbi had short term disability; in another study 4.6% of the patients sustained long-term disability. Conclusions: there is great heterogeneity in the cost studies. There is no consensus for assessing the quality of these studies. The indirect costs incurred in traffic accidents are greater than direct costs. The costs of disability and rehabilitation are poorly assessed.RESUMEN: Conocer los costos directos (cd) e indirectos (ci) de la atención de pacientes con lesiones por accidentes de tránsito (at) en el mundo.

Musculoskeletal evaluation in severe haemophilia A patients from Latin America

There is a paucity of literature on haemophilia treatment in Latin American countries, a region characterized by rapidly improving systems of care, but with substantial disparities in treatment between countries. The aim of this study was to evaluate the musculoskeletal status of haemophilia patients from Latin America and to examine the relationship between musculoskeletal status and treatment practices across countries. The Committee of Latin America on the Therapeutics of Inhibitor Groups conducted a survey of its member country representatives on key aspects of haemophilia treatment in 10 countries. Musculoskeletal status of patients was obtained during routine comprehensive evaluations between March 2009 and March 2011. Eligible patients had severe haemophilia A (factor VIII <1%) without inhibitors (<0.6 BU mL−1) and were ≥5 years of age. Musculoskeletal status was compared between three groups of countries, based primarily on differences in the availability of long‐term prophylaxis. Overall, 143 patients (5–66 years of age) were enrolled from nine countries. In countries where long‐term prophylaxis had been available for at least 10 years (Group A), patients aged 5–10 years had significantly better mean World Federation of Hemophilia clinical scores, fewer target joints and fewer affected joints than patients from countries where long‐term prophylaxis has been available for about 5 years (Group B) or was not available (Group C). In Latin America, the musculoskeletal status of patients with severe haemophilia without inhibitors has improved significantly in association with the provision of long‐term prophylaxis. As more countries in Latin America institute this practice, further improvements are anticipated

Mental Health Disturbance after a Major Earthquake in Northern Peru: A Preliminary, Cross-Sectional Study

Little has been studied in Peru on the mental health repercussions after a major earthquake.We aimed to explore the factors associated with depressive and anxiety symptoms in people whoexperienced a 6.1 magnitude earthquake in Piura, Peru, on 30 July 2021. A preliminary cross-sectional study was conducted in the general population between August–September 2021. An onlinequestionnaire was provided using PHQ-9, GAD-7, and other relevant measures. Generalized linearmodels were applied. Of the 177 participants, the median age was 22 years, the majority were female(56%), and many experienced depressive (52%) or anxiety symptoms (52%). Presence of depressivesymptoms was associated with a personal history of mental disorder, moderate housing damage,social/material support from politicians, moderate food insecurity, and insomnia. Presence of anxietysymptoms was associated with physical injury caused by the earthquake, mild food insecurity, andinsomnia. The development of depressive and anxiety symptoms following the 2021 earthquakeexperienced in Piura depended on multiple individual and socioeconomic factors. Additional studiesshould reinforce the factors identified here given the methodological limitations, such as the studydesign, sampling method, and sample size. This would lead to effective intervention measures tomitigate the impact of earthquakes on mental health

Secretory immunoglobulin A (s-IgA) reactivity to acute psychosocial stress in children and adolescents: The influence of pubertal development and history of maltreatment.

Background: Mucosal secretory immunoglobulin A (s-IgA) is an antibody protein-complex that plays a crucial role in immune first defense against infection. Although different immune biomarkers have been associated with stress-related psychopathology, s-IgA remains poorly studied, especially in youth. Objectives: The present study investigated how s-IgA behaves in front of acute psychosocial stress in children and adolescents, including possible variability associated with developmental stage and history of childhood maltreatment (CM). Methods: 94 children and adolescents from 7 to 17 years (54 with a current psychiatric diagnostic and 40 healthy controls) drawn from a larger Spanish study were explored (EPI-Young Stress Project). To assess biological reactivity, participants provided five saliva samples during an acute laboratory-based psychosocial stressor, the Trier Social Stress Test for Children (TSST-C). Samples were assayed for s-IgA, as well as for cortisol. Pubertal development was ascertained by Tanner stage and CM following TASSCV criteria. Results: We observed s-IgA fluctuations throughout the stressor, indicating the validity of TSST-C to stimulate s-IgA secretion (F(4,199) = 6.200, p <.001). Although s-IgA trajectories followed a reactivity and recovery pattern in adolescents, children exhibited no s-IgA response when faced with stress (F(4,197) = 3.406, p =.010). An interaction was found between s-IgA and CM (F(4,203) = 2.643, p =.035). Interestingly, an interaction between developmental stage, CM history and s-IgA reactivity was identified (F(12,343) = 2.036, p =.017); while children non-exposed to maltreatment exhibited no s-IgA changes to acute stress, children with a history of CM showed a similar response to adolescents, increasing their s-IgA levels after the psychosocial stressor. Conclusion: Acute psychosocial stress stimulates s-IgA secretion, but only after puberty. However, children with a history of maltreatment exhibited a response resembling that of adolescents, suggesting an early maturation of the immune system. Further studies are needed to clarify the validity of s-IgA as an acute stress biomarker, including additional measures during stress exposure.

Dopaminergic control of ADAMTS2 expression through cAMP/CREB and ERK: molecular effects of antipsychotics

A better understanding of the molecular mechanisms that participate in the development and clinical manifestations of schizophrenia can lead to improve our ability to diagnose and treat this disease. Previous data strongly associated the levels of deregulated ADAMTS2 expression in peripheral blood mononuclear cells (PBMCs) from patients at first episode of psychosis (up) as well as in clinical responders to treatment with antipsychotic drugs (down). In this current work, we performed an independent validation of such data and studied the mechanisms implicated in the control of ADAMTS2 gene expression. Using a new cohort of drug-naïve schizophrenia patients with clinical follow-up, we confirmed that the expression of ADAMTS2 was highly upregulated in PBMCs at the onset (drug-naïve patients) and downregulated, in clinical responders, after treatment with antipsychotics. Mechanistically, ADAMTS2 expression was activated by dopaminergic signalling (D1-class receptors) and downstream by cAMP/CREB and mitogen-activated protein kinase (MAPK)/ERK signalling. Incubation with antipsychotic drugs and selective PKA and MEK inhibitors abrogated D1-mediated activation of ADAMTS2 in neuronal-like cells. Thus, D1 receptors signalling towards CREB activation might participate in the onset and clinical responses to therapy in schizophrenia patients, by controlling ADAMTS2 expression and activity. The unbiased investigation of molecular mechanisms triggered by antipsychotic drugs may provide a new landscape of novel targets potentially associated with clinical efficacy.Acknowledgements: We are highly indebted to the participants and their families for their cooperation in this study.

Retos del aula invertida para la formación universitaria en la Región Austral

La educación es un proceso continuo que ocurre a lo largo de la vida y en diversos contextos. El sistema educativo debe procurar que su finalidad vaya más allá de la mera transmisión de información. Si bien es importante que los estudiantes adquieran conocimientos en cada disciplina, es aún más crucial que aprendan a buscar información, evaluarla críticamente, generar nueva información, apreciar diversas formas de conocimiento, utilizar herramientas tecnológicas, desarrollar valores, aplicar conocimiento a la resolución de problemas, y se involucran en proyectos individuales y colectivos que respondan a las demandas de su sociedad. Según Tourón, Santiago y Díez (2014), el conocimiento se crea cuando los individuos son capaces de atribuir significado a la información, y es tarea de la educación transformar la información en conocimiento. Así, esta investigación tiene como objetivo explorar cómo la implementación del modelo pedagógico Flipped Classroom en una institución educativa chilena ha permitido a los estudiantes y futuros ciudadanos desarrollar las habilidades, destrezas y actitudes del socio constructivismo que son esenciales para la sociedad del siglo XX
