The effect of burnout in seniority in the workplace: mediation analysis of anxiety

Cada vez en mayor medida se hace patente que el síndrome de burnout es una realidad social. Esta disfunción psicológica está relacionada directamente con el ámbito laboral, que afecta especialmente a la profesión sanitaria, caracterizada por una continua relación de ayuda indispensable hacia otras personas, que a su vez dependen del citado personal. La muestra de estudio es de 70 trabajadores de un mismo centro del sector sanitario de atención de mayores de la ciudad de Granada. Los resultados muestran que la ansiedad se relacionará positivamente tanto con el burnout como con la antigüedad en el puesto, mientras que predecimos que a menor realización personal en presencia de mayor antigüedad los valores en ansiedad también serán más altos. También se comprueba que la ansiedad estado tiene efectos mediadores sobre la realización personal, puesto que puede causar mayor alteración de este estado que la propia antigüedad.As time goes by it becomes more and more evident that burnout syndrome is a social reality. This psychological dysfunction is directly related to the spheres of labour, especially affecting the sanitary profession, characterized by a continuous relationship of indispensable help towards others, who are dependent on them. The study sample comprised 70 workers of the same healthcare center focusing on elderly care in Granada. The results show that anxiety will correlate positively with burnout as well as with seniority at the job, while we predict anxiety levels will also be higher if there is low personal fulfilment in the presence of more job seniority. It is also proved that a state of anxiety has a mediating effect on personal fulfilment since it can cause a greater alteration in this state than job seniority.Departamento de Psicología Socia

TGFBR1 Intralocus Epistatic Interaction as a Risk Factor for Colorectal Cancer

In colorectal cancer (CRC), an inherited susceptibility risk affects about 35% of patients, whereas high-penetrance germline mutations account for <6% of cases. A considerable proportion of sporadic tumors could be explained by the coinheritance of multiple low-penetrance variants, some of which are common. We assessed the susceptibility to CRC conferred by genetic variants at the TGFBR1 locus. We analyzed 14 polymorphisms and the allele-specific expression (ASE) of TGFBR1 in 1025 individuals from the Spanish population. A case-control study was undertaken with 504 controls and 521 patients with sporadic CRC. Fourteen polymorphisms located at the TGFBR1 locus were genotyped with the iPLEX Gold (MassARRAY-Sequenom) technology. Descriptive analyses of the polymorphisms and haplotypes and association studies were performed with the SNPator workpackage. No relevant associations were detected between individual polymorphisms or haplotypes and the risk of CRC. The TGFBR1*9A/6A polymorphism was used for the ASE analysis. Heterozygous individuals were analyzed for ASE by fragment analysis using cDNA from normal tissue. The relative level of allelic expression was extrapolated from a standard curve. The cutoff value was calculated with Youden's index. ASE was found in 25.4% of patients and 16.4% of controls. Considering both bimodal and continuous types of distribution, no significant differences between the ASE values of patients and controls were identified. Interestingly, a combined analysis of the polymorphisms and ASE for the association with CRC occurrence revealed that ASE-positive individuals carrying one of the most common haplotypes (H2: 20.7%) showed remarkable susceptibility to CRC (RR: 5.25; 95% CI: 2.547–5.250; p<0.001) with a synergy factor of 3.7. In our study, 54.1% of sporadic CRC cases were attributable to the coinheritance of the H2 haplotype and TGFBR1 ASE. These results support the hypothesis that the allelic architecture of cancer genes, rather than individual polymorphisms, more accurately defines the CRC risk

Non-relativistic Matrix Inflation

We reconsider a string theoretic inflationary model, where inflation is driven by $n$ multiple coincident $D3$-branes in the finite $n$ limit. We show that the finite $n$ action can be continued to the limit of large $n$, where it converges to the action for a wrapped $D5$-brane with $n$ units of U(1) flux. This provides an important consistency check of the scenario and allows for more control over certain back-reaction effects. We determine the most general form of the action for a specific sub-class of models and examine the non-relativistic limits of the theory where the branes move at speeds much less than the speed of light. The non-Abelian nature of the world-volume theory implies that the inflaton field is matrix valued and this results in modifications to the slow-roll parameters and Hubble-flow equations. A specific small field model of inflation is investigated where the branes move out of an AdS throat, and observational constraints are employed to place bounds on the background fluxes.Comment: 25 page

Dreams and nightmares of liberal international law: capitalist accumulation, natural rights and state hegemony

This article develops a line of theorising the relationship between peace, war and commerce and does so via conceptualising global juridical relations as a site of contestation over questions of economic and social justice. By sketching aspects of a historical interaction between capitalist accumulation, natural rights and state hegemony, the article offers a critical account of the limits of liberal international law, and attempts to recover some ground for thinking about the emancipatory potential of international law more generally

Increased Systemic Th17 Cytokines Are Associated with Diastolic Dysfunction in Children and Adolescents with Diabetic Ketoacidosis

Diastolic dysfunction suggestive of diabetic cardiomyopathy is established in children with T1DM, but its pathogenesis is not well understood. We studied the relationships of systemic inflammatory cytokines/chemokines and cardiac function in 17 children with T1DM during and after correction of diabetic ketoacidosis (DKA). Twenty seven of the 39 measured cytokines/chemokines were elevated at 6–12 hours into treatment of DKA compared to values after DKA resolution. Eight patients displayed at least one parameter of diastolic abnormality (DA) during acute DKA. Significant associations were present between nine of the cytokine/chemokine levels and the DA over time. Interestingly, four of these nine interactive cytokines (GM-CSF, G-CSF, IL-12p40, IL-17) are associated with a Th17 mediated cell response. Both the DA and CCL7 and IL-12p40, had independent associations with African American patients. Thus, we report occurrence of a systemic inflammatory response and the presence of cardiac diastolic dysfunction in a subset of young T1DM patients during acute DKA

Urban greenspaces and nearby natural areas support similar levels of soil ecosystem services

Yet their capacity to support multiple ecosystem services simultaneously (multiservices) compared with nearby natural ecosystems remains virtually unknown. We conducted a global field survey in 56 urban areas to investigate the influence of urban greenspaces on 23 soil and plant attributes and compared them with nearby natural environments. We show that, in general, urban greenspaces and nearby natural areas support similar levels of soil multiservices, with only six of 23 attributes (available phosphorus, water holding capacity, water respiration, plant cover, arbuscular mycorrhizal fungi (AMF), and arachnid richness) significantly greater in greenspaces, and one (available ammonium) greater in natural areas. Further analyses showed that, although natural areas and urban greenspaces delivered a similar number of services at low (>25% threshold) and moderate (>50%) levels of functioning, natural systems supported significantly more functions at high (>75%) levels of functioning. Management practices (mowing) played an important role in explaining urban ecosystem services, but there were no effects of fertilisation or irrigation. Some services declined with increasing site size, for both greenspaces and natural areas. Our work highlights the fact that urban greenspaces are more similar to natural environments than previously reported and underscores the importance of managing urban greenspaces not only for their social and recreational values, but for supporting multiple ecosystem services on which soils and human well-being depends.Supported by a 2019 Leonardo Grant for Researchers and Cultural Creators, BBVA Foundation (URBANFUN); the BES grant agreement No LRB17\1019 (MUSGONET); the Spanish Ministry of Science and Innovation for the I + D + i project PID2020-115813RA-I00 funded by MCIN/AEI/10.13039/501100011033; a project of the Fondo Europeo de Desarrollo Regional (FEDER) and the Consejería de Transformación Económica, Industria, Conocimiento y Universidades of the Junta de Andalucía; the Hermon Slade Foundation; the National Natural Science Foundation of China; the Young Science and Technology Talent Support Project of Jilin Province; Young Elite Scientists Sponsorship Program by BAST; the Fundamental Research Funds for the Central Universities; a Ramón y Cajal grant from Spanish Ministry of Science and Innovation; FONDECYT; the EU’s H2020 research and innovation programme; FCT/MCTES through national funds (PIDDAC); the National Research Foundation of South Africa; the Slovenian Research Agency; the SERB, DST and Banaras Hindu University; the Program for Introducing Talents to Universities and the Ministry of Education Innovation Team Development Plan.https://www.nature.com/npjurbansustainhj2024BiochemistryGeneticsMicrobiology and Plant PathologySDG-15:Life on lan

Biogenic factors explain soil carbon in paired urban and natural ecosystems worldwide

DATA AVAILABILITY : The raw data associated with this study are available in https://figshare.com/s/1eadef6619e74a8f2904 (https://doi.org/10.6084/m9.figshare.21025615).Urban greenspaces support multiple nature-based services, many of which depend on the amount of soil carbon (C). Yet, the environmental drivers of soil C and its sensitivity to warming are still poorly understood globally. Here we use soil samples from 56 paired urban greenspaces and natural ecosystems worldwide and combine soil C concentration and size fractionation measures with metagenomics and warming incubations. We show that surface soils in urban and natural ecosystems sustain similar C concentrations that follow comparable negative relationships with temperature. Plant productivity’s contribution to explaining soil C was higher in natural ecosystems, while in urban ecosystems, the soil microbial biomass had the greatest explanatory power. Moreover, the soil microbiome supported a faster C mineralization rate with experimental warming in urban greenspaces compared with natural ecosystems. Consequently, urban management strategies should consider the soil microbiome to maintain soil C and related ecosystem services.This study was supported by a 2019 Leonardo Grant for Researchers and Cultural Creators, BBVA Foundation (URBANFUN), and by BES Grant.

Unearthing the soil-borne microbiome of land plants

DATA AVAILABILITY STATEMENT : Data from this manuscript is available at 10.6084/m9.figshare.25254673.Plant–soil biodiversity interactions are fundamental for the functioning of terrestrial ecosystems. Yet, the existence of a set of globally distributed topsoil microbial and small invertebrate organisms consistently associated with land plants (i.e., their consistent soil-borne microbiome), together with the environmental preferences and functional capabilities of these organisms, remains unknown. We conducted a standardized field survey under 150 species of land plants, including 58 species of bryophytes and 92 of vascular plants, across 124 locations from all continents. We found that, despite the immense biodiversity of soil organisms, the land plants evaluated only shared a small fraction (less than 1%) of all microbial and invertebrate taxa that were present across contrasting climatic and soil conditions and vegetation types. These consistent taxa were dominated by generalist decomposers and phagotrophs and their presence was positively correlated with the abundance of functional genes linked to mineralization. Finally, we showed that crossing environmental thresholds in aridity (aridity index of 0.65, i.e., the transition from mesic to dry ecosystems), soil pH (5.5; i.e., the transition from acidic to strongly acidic soils), and carbon (less than 2%, the lower limit of fertile soils) can result in drastic disruptions in the associations between land plants and soil organisms, with potential implications for the delivery of soil ecosystem processes under ongoing global environmental change.British Ecological Society; Slovenian Research Agency; Junta de Andalucía; Spanish Ministry of Science and Innovation.http://www.wileyonlinelibrary.com/journal/gcbhj2024BiochemistryGeneticsMicrobiology and Plant PathologySDG-15:Life on lan

The global contribution of soil mosses to ecosystem services

DATA AVAILABILITY : All the materials, raw data, and protocols used in the article are available upon request. Data used in this study can be found in the Figshare data repository https://figshare.com/s/b152d06e53066d08b934 ref.Soil mosses are among the most widely distributed organisms on land. Experiments and observations suggest that they contribute to terrestrial soil biodiversity and function, yet their ecological contribution to soil has never been assessed globally under natural conditions. Here we conducted the most comprehensive global standardized field study to quantify how soil mosses influence 8 ecosystem services associated with 24 soil biodiversity and functional attributes across wide environmental gradients from all continents. We found that soil mosses are associated with greater carbon sequestration, pool sizes for key nutrients and organic matter decomposition rates but a lower proportion of soil-borne plant pathogens than unvegetated soils. Mosses are especially important for supporting multiple ecosystem services where vascular-plant cover is low. Globally, soil mosses potentially support 6.43 Gt more carbon in the soil layer than do bare soils. The amount of soil carbon associated with mosses is up to six times the annual global carbon emissions from any altered land use globally. The largest positive contribution of mosses to soils occurs under perennial, mat and turf mosses, in less-productive ecosystems and on sandy soils. Our results highlight the contribution of mosses to soil life and functions and the need to conserve these important organisms to support healthy soils.A Large Research Grant from the British Ecological Society; the Hermon Slade Foundation; a Ramón y Cajal grant from the Spanish Ministry of Science and Innovation; the Junta de Andalucía; the European Research Council; the AEI; the Program for Introducing Talents to Universities; the Ministry of Education Innovation Team Development Plan; the Research Program in Forest Biology, Ecology and Technology; the Slovenian Research Agency; the NSF Biological Integration Institutes; the FCT and FCT/MCTES through national funds (PIDDAC).http://www.nature.com/ngeo/hj2024BiochemistryGeneticsMicrobiology and Plant PathologySDG-15:Life on lan
