    Burnout syndrome seems to involve fatigue that is characterised by loss of motivation, lack of energy, and some apathy as a consequence of continued exposure to stress in demanding performance circumstances. Background: The goal of the present study is to analyse the relationship between burnout in university students with a degree in Teaching and some variables that may be associated with it such as self-esteem, resilience or age. Methods: A total of 1547 graduate students enrolled in the career of Teaching in the Faculty of Educational Sciences of the University of Granada, Spain, participated in the study. Of them, 337 (21.8%) were men, 1195 (77.3%) were women, 14 (0.9%) indicated other gender options, and 1 (0%) did not respond to this item. The mean age of the participants was 20.52. Results: The results show that low levels of self-esteem and resilience, are the variables that best predict the increase in burnout in students of Teaching. Conclusions: Findings are discussed regarding applied implications and the need for future research. Intervention initiatives focused on enhancing personal strengths such as resilience or self-esteem can help students to cope with the stress associated with demanding educational situations and thus reduce the presence of burnout

    Resilience is the ability of the person to face adverse situations and emerge stronger from them. On the other hand, self-esteem is the general assessment that a person makes of himself. In the educational field, situations that can be related to both factors converge. Not too many studies have focused so far on knowing how these variables evolve during the training of future teachers. In the present study, we intend to check the levels of self-esteem and resilience in a sample of teaching students as well as to explore whether there is an association between the different levels of self-esteem and the resilience of the participants. (is is a crosssectional descriptive investigation through an evaluation instrument. (e sample consists of 1547 students aged 17–57 years. (e sample consisted of 916 primary education students (59.2%) and 631 early childhood education students (40.8%). Of these, 337 were men, 1195 were women, and 14 of them did not indicate their gender. (e results confirm a positive association between selfesteem and resilience. Furthermore, an increase in the levels of both variables has been found as students progress in their studies. (ese data verify that the students seem to be in a position to face adverse situations, as well as qualified to transfer these competencies during the performance of their future teaching work

    Chronic kidney disease (CKD) is a major risk factor for end-stage renal disease, cardiovascular disease and premature death. Despite classical clinical risk factors for CKD and some genetic risk factors have been identified, the residual risk observed in prediction models is still high. Therefore, new risk factors need to be identified in order to better predict the risk of CKD in the population. Here, we analyzed the genetic association of 79 SNPs of proteins associated with mineral metabolism disturbances with CKD in a cohort that includes 2,445 CKD cases and 559 controls. Genotyping was performed with matrix assisted laser desorption ionization-time of flight mass spectrometry. We used logistic regression models considering different genetic inheritance models to assess the association of the SNPs with the prevalence of CKD, adjusting for known risk factors. Eight SNPs (rs1126616, rs35068180, rs2238135, rs1800247, rs385564, rs4236, rs2248359, and rs1564858) were associated with CKD even after adjusting by sex, age and race. A model containing five of these SNPs (rs1126616, rs35068180, rs1800247, rs4236, and rs2248359), diabetes and hypertension showed better performance than models considering only clinical risk factors, significantly increasing the area under the curve of the model without polymorphisms. Furthermore, one of the SNPs (the rs2248359) showed an interaction with hypertension, being the risk genotype affecting only hypertensive patients. We conclude that 5 SNPs related to proteins implicated in mineral metabolism disturbances (Osteopontin, osteocalcin, matrix gla protein, matrix metalloprotease 3 and 24 hydroxylase) are associated to an increased risk of suffering CKD

    Chronic kidney disease (CKD) is associated with an elevated risk of all-cause mortality, with cardiovascular death being extensively investigated. However, non-cardiovascular mortality represents the biggest percentage, showing an evident increase in recent years. Klotho is a gene highly expressed in the kidney, with a clear influence on lifespan. Low levels of Klotho have been linked to CKD progression and adverse outcomes. Single nucleotide polymorphisms (SNPs) of the Klotho gene have been associated with several diseases, but studies investigating the association of Klotho SNPs with noncardiovascular death in CKD populations are lacking. The main aim of this study was to assess whether 11 Klotho SNPs were associated with non-cardiovascular death in a subpopulation of the National Observatory of Atherosclerosis in Nephrology (NEFRONA) study (n ¼ 2185 CKD patients). After 48 months of follow-up, 62 cardiovascular deaths and 108 non-cardiovascular deaths were recorded. We identified a high non-cardiovascular death risk combination of SNPs corresponding to individuals carrying the most frequent allele (G) at rs562020, the rare allele (C) at rs2283368 and homozygotes for the rare allele (G) at rs2320762 (rs562020 GG/AG þ rs2283368 CC/CT þ rs2320762 GG). Among the patients with the three SNPs genotyped (n ¼ 1016), 75 (7.4%) showed this combination. Furthermore, 95 (9.3%) patients showed a low-risk combination carrying all the opposite genotypes (rs562020 AA þ rs2283368 TT þ rs2320762 GT/TT). All the other combinations [n ¼ 846 (83.3%)] were considered as normal risk. Using competing risk regression analysis, we confirmed that the proposed combinations are independently associated with a higher fhazard ratio [HR] 3.28 [confidence interval (CI) 1.51-7.12]g and lower [HR 6 × 10- (95% CI 3.3 × 10--1.1 × 10-)] risk of suffering a non-cardiovascular death in the CKD population of the NEFRONA cohort compared with patients with the normal-risk combination. Determination of three SNPs of the Klotho gene could help in the prediction of non-cardiovascular death in CKD

    The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

    Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation

    Field trials have been carried out to determine the variability of residue levels of fenitrothion and its main metabolites fenitrothion-oxon and 3-methyl-4-nitrophenol in individual kaki fruits versus composite samples, in peel versus flesh, and in whole uncooked versus whole cooked fruits. Residue levels have been determined by gas chromatography with thermionic specific detection after extraction with ethyl acetate and without further cleanup. At harvest, residue levels of fenitrothion were below maximum residue levels (MRLs) and the two metabolites 3-methyl-4-nitrophenol and fenitrothionoxon could be quantified with average amounts of 0.080 and 0.012 mg/kg, respectively. Levels of fenitrothion decreased 88% after peeling, whereas temperature did not result in a high variation. The ratios of the highest residue level in the individual fruits to the corresponding mean of residue levels in the composite samples for fenitrothion were <3. This value is lower than that recommended by the World Health Organization as default value for consumer risk assessment

    Se analiza la importancia de la investigación en la patogenia de la pancreatitis aguda (PA) con estudios experimentales en animales. Cuando las investigaciones están orientadas en intervenciones terapéuticas no existe concordancia en los resultados, dado que los pacientes ingresan con varias horas de evolución. Se especifican los puntos que un modelo animal debe reunir para estudiar esta enfermedad. Se describen las causas etiológicas más importantes y su incidencia. La cascada de acontencimientos a escala celular y sistémica es similar en todas las etiologías y se inicia por bloqueo de la secreción de proteínas en los conductos acinares del páncreas, activándose el tripsinógeno dentro de la célula acinar y dando lugar al proceso de la autodigestión. El daño en las células acinares y en el endotelio vascular por las enzimas pancreáticas activadas conlleva la liberación de mediadores inflamatorios y trastornos en la microcirculación; según la extensión de estas lesiones se desencadena el grado de deterioro del tejido pancreático, sin estar claro los factores que pueden frenar la necrosis. Posteriormente se extiende el daño al espacio peripancreático y pasan a la circulación sistémica enzimas pancreáticas activadas y mediadores inflamatorios (citocinas),y según la respuesta inmunológica del paciente, se condiciona el grado de afectación general y la disfunción orgánica, causa de mortalidad tanto temprana como tardía
