This paper aims to explore the role of Child Well-Being (CWB) in the integration processes of migrant and refugee minors. Through the co-creative development of a new child-centered system of indicators about the integration of migrant and refugee children in Europe the authors discuss a) the prominent role of well-being in this set of indicators, and b) how reappraising these indicators from a well-being approach can contribute to delving into which aspects of CWB are connected to the integration of migrant children. The contributions of this paper open new research paths: on the one hand, the methodology presented provides a reference for future research that can replicate the procedure to build child-centered indicators in disciplines different than migration studies; on the other hand, the results presented suggest not only that well-being has a prominent role in migrant children integration experiences, but also, that reappraising dimensions of migrant children's integration from a well-being approach hints at blurry borders between both concepts. This suggests promising research opportunities to underpin the relationship between integration and well-being., Author(s): Eva Bajo Marcos [sup.1] , Mercedes Fernández [sup.1] , Inmaculada Serrano [sup.1] Author Affiliations: (1) grid.11108.39, 0000 0001 2324 8920, University Institute of Studies on Migration, Comillas Pontifical University, [...]

A new series of [Fe3−xLnx]O4 nanoparticles, with Ln = Gd; Dy; Lu and x = 0.05; 0.1; 0.15, was synthesized using the coprecipitation method. Analyses by X-ray diffraction (XRD), Rietveld refinement, and high-resolution transmission electron microscopy (HRTEM) indicate that all phases crystallized in space group F d 3 ¯ m , characteristic of spinels. The XRD patterns, HRTEM, scanning electron microscopy analysis (SEM-EDS), and Raman spectra showed single phases. Transmission electron microscopy (TEM), Rietveld analysis, and Scherrer's calculations confirm that these materials are nanoparticles with sizes in the range of ~6 nm to ~13 nm. Magnetic measurements reveal that the saturation magnetization (Ms) of the as-prepared ferrites increases with lanthanide chemical substitution (x), while the coercivity (Hc) has low values. The Raman analysis confirms that the compounds are ferrites and the Ms behavior can be explained by the relationship between the areas of the signals. The magnetic measurements indicate superparamagnetic behavior. The blocking temperatures (TB) were estimated from ZFC-FC measurements, and the use of the Néel equation enabled the magnetic anisotropy to be estimated. [ABSTRACT FROM AUTHOR]

The application of bacterial metagenomic analysis as a biomarker for cancer detection is emerging. Our aim was to discover gut microbiota signatures with potential utility in the diagnosis of colorectal cancer (CRC) and non-small cell lung cancer (NSCLC). A prospective study was performed on a total of 77 fecal samples from CRC and NSCLC patients and controls. DNA from stool was analyzed for bacterial genomic sequencing using the Ion Torrent™ technology. Bioinformatic analysis was performed using the QIIME2 pipeline. We applied logistic regression to adjust for differences attributable to sex, age, and body mass index, and the diagnostic accuracy of our gut signatures was compared with other previously published results. The feces of patients affected by different tumor types, such as CRC and NSCLC, showed a differential intestinal microbiota profile. After adjusting for confounders, Parvimonas (OR = 53.3), Gemella (OR = 6.01), Eisenbergiella (OR = 5.35), Peptostreptococcus (OR = 9.42), Lactobacillus (OR = 6.72), Salmonella (OR = 5.44), and Fusobacterium (OR = 78.9) remained significantly associated with the risk of CRC. Two genera from the Ruminococcaceae family, DTU089 (OR = 20.1) and an uncharacterized genus (OR = 160.1), were associated with the risk of NSCLC. Our two panels had better diagnostic capacity for CRC (AUC = 0.840) and NSLC (AUC = 0.747) compared to the application of two other published panels to our population. Thus, we propose a gut bacteria panel for each cancer type and show its potential application in cancer diagnosis. [ABSTRACT FROM AUTHOR]
