Do governments care about socioeconomic inequalities in health? Narrative review of reports of EU-15 countries

Altres ajuts: Fundació "La Caixa"Socioeconomic inequalities in health have been an issue in all European countries since the publication of the "Black Report" in the United Kingdom in 1980. However, data show that nowadays there are important socioeconomic health inequalities within EU countries. The purpose of this paper is to review EU-15 government reports that address socioeconomic inequalities in health. We reviewed 101 reports. The pioneer countries in analyzing this topic have a Beveridge-type health system, and they are the leaders over time. The top socioeconomic indicators used are education level, social class, deprivation level of the area, and nationality. Given the current COVID-19 pandemic situation and its economic consequences, EU governments need to continue monitoring the existing inequalities in health and to act transversely in all public policies

La villa romana de Las Viñas (Cuevas del Becerro, Málaga) y el poblamiento rural romano en la depresión de Ronda.

En base a los resultados obtenidos en la excavación de urgencia realizada en la villa romana de "Las Viñas" (Cuevas del Becerro, Málaga) se presenta una interpretación histórica de la misma, así como inferencias sobre el desarrollo del poblamiento urbano y rural de la Depresión de Ronda. Se destaca el resultado obtenido del análisis de los contenidos de cerámicas halladas en una cella de la villa, el cual nos indica que parte de las construcciones documentadas fueron utilizadas para la obtención de aceite de oliva.From the results obtained in an urgency excavation carried out in the roman villa "Las Viñas" (Cuevas del Becerro, Málaga), an historical interpretation of the villa and inferences on the development of the rural and urban settlement in the Ronda Basin are made. To point out the results obtained from the analysis of there ceramic containers found in one of the cellae in the villa, which indicate that part of the documented building structures were utilized for manufacturing olive oil

Large-Scale Screening of a Targeted Enterococcus faecalis Mutant Library Identifies Envelope Fitness Factors

Spread of antibiotic resistance among bacteria responsible for nosocomial and community-acquired infections urges for novel therapeutic or prophylactic targets and for innovative pathogen-specific antibacterial compounds. Major challenges are posed by opportunistic pathogens belonging to the low GC% Gram-positive bacteria. Among those, Enterococcus faecalis is a leading cause of hospital-acquired infections associated with life-threatening issues and increased hospital costs. To better understand the molecular properties of enterococci that may be required for virulence, and that may explain the emergence of these bacteria in nosocomial infections, we performed the first large-scale functional analysis of E. faecalis V583, the first vancomycin-resistant isolate from a human bloodstream infection. E. faecalis V583 is within the high-risk clonal complex 2 group, which comprises mostly isolates derived from hospital infections worldwide. We conducted broad-range screenings of candidate genes likely involved in host adaptation (e.g., colonization and/or virulence). For this purpose, a library was constructed of targeted insertion mutations in 177 genes encoding putative surface or stress-response factors. Individual mutants were subsequently tested for their i) resistance to oxidative stress, ii) antibiotic resistance, iii) resistance to opsonophagocytosis, iv) adherence to the human colon carcinoma Caco-2 epithelial cells and v) virulence in a surrogate insect model. Our results identified a number of factors that are involved in the interaction between enterococci and their host environments. Their predicted functions highlight the importance of cell envelope glycopolymers in E. faecalis host adaptation. This study provides a valuable genetic database for understanding the steps leading E. faecalis to opportunistic virulence

Subgenomic RNA identification in SARS-CoV-2 genomic sequencing data

We have developed periscope, a tool for the detection and quantification of subgenomic RNA (sgRNA) in SARS-CoV-2 genomic sequence data. The translation of the SARS-CoV-2 RNA genome for most open reading frames (ORFs) occurs via RNA intermediates termed “subgenomic RNAs.” sgRNAs are produced through discontinuous transcription, which relies on homology between transcription regulatory sequences (TRS-B) upstream of the ORF start codons and that of the TRS-L, which is located in the 5′ UTR. TRS-L is immediately preceded by a leader sequence. This leader sequence is therefore found at the 5′ end of all sgRNA. We applied periscope to 1155 SARS-CoV-2 genomes from Sheffield, United Kingdom, and validated our findings using orthogonal data sets and in vitro cell systems. By using a simple local alignment to detect reads that contain the leader sequence, we were able to identify and quantify reads arising from canonical and noncanonical sgRNA. We were able to detect all canonical sgRNAs at the expected abundances, with the exception of ORF10. A number of recurrent noncanonical sgRNAs are detected. We show that the results are reproducible using technical replicates and determine the optimum number of reads for sgRNA analysis. In VeroE6 ACE2+/− cell lines, periscope can detect the changes in the kinetics of sgRNA in orthogonal sequencing data sets. Finally, variants found in genomic RNA are transmitted to sgRNAs with high fidelity in most cases. This tool can be applied to all sequenced COVID-19 samples worldwide to provide comprehensive analysis of SARS-CoV-2 sgRNA

Differential Phenotypic and Functional Profiles of TcCA-2 -Specific Cytotoxic CD8+ T Cells in the Asymptomatic versus Cardiac Phase in Chagasic Patients

It has been reported that the immune response mediated by T CD8+ lymphocytes plays a critical role in the control of Trypanosoma cruzi infection and that the clinical symptoms of Chagas disease appear to be related to the competence of the CD8+ T immune response against the parasite. Herewith, in silico prediction and binding assays on TAP-deficient T2 cells were used to identify potential HLA-A*02:01 ligands in the T. cruzi TcCA-2 protein. The TcCA-2-specific CD8+ T cells were functionality evaluated by Granzyme B and cytokine production in peripheral blood mononuclear cells (PBMC) from Chagas disease patients stimulated with the identified HLA-A*02:01 peptides. The specific cells were phenotypically characterized by flow cytometry using several surface markers and HLA-A*02:01 APC-labeled dextramer loaded with the peptides. In the T. cruzi TcCA-2 protein four T CD8+ epitopes were identified which are processed and presented during Chagas disease. Interestingly, a differential cellular phenotypic profile could be correlated with the severity of the disease. The TcCA-2-specific T CD8+ cells from patients with cardiac symptoms are mainly effector memory cells (TEM and TEMRA) while, those present in the asymptomatic phase are predominantly naive cells (TNAIVE). Moreover, in patients with cardiac symptoms the percentage of cells with senescence features is significantly higher than in patients at the asymptomatic phase of the disease. We consider that the identification of these new class I-restricted epitopes are helpful for designing biomarkers of sickness pathology as well as the development of immunotherapies against T. cruzi infection.This work was supported by grants SAF2012-35777 and SAF2013-48527-R from Programa Estatal I+D+i (MINECO); Network of Tropical Diseases Research RICET, grants RD12/0018/0021 and RD12/0018/0018 (MSSSI, Spain) and FEDER.
