    Introduction: The voluntary interruption of pregnancy (VIP) is a complex process, influenced both by health and psychosocial factors, which in turn affect the health and well-being of the women. The objective of this study is to determine the factors related to the voluntary interruption of pregnancy in Spain, in women with more than one interruption, according to their origin. Methods: A cross-sectional study of the VIP episodes carried out at the request of the women themselves in Spain during 2018. The factors related to repeat VIPs are described according to the origin of the women, estimating the crude and adjusted prevalence odds ratio (OR). Results: The highest rates of VIP occurred in women aged 20 to 24 years. The probability of a second VIP, both in Spanish women and those of foreign origin, increased with age, with the size of the population (> 50,000 inhabitants), and with dependent children. Conclusions: All women should have the possibility of planning their reproductive life, for which they have the right to have access to adequate information, to effective contraceptive methods, and to be able to interrupt an unplanned pregnancy with all the guarantees of quality, confidentiality and safety.S

    En esta investigación nos planteamos conocer el grado de satisfacción que los estudiantes universitarios tienen respecto a la experiencia formativa no presencial de los procesos de enseñanza-aprendizaje en tiempos de pandemia. Para evaluar ese nivel de satisfacción se ha aplicado un cuestionario, que hemos adaptado de unas escalas estandarizadas de satisfacción de alumnos universitarios con respecto a la formación online, CSAUF, (Monsalve-Gómez et. al., 2014) y semipresencial (Cabero, et al., 2010), a 64 estudiantes universitarios, elegidos al azar, de ambos géneros, con edades comprendidas entre los 23 y más de 30 años y que en la actualidad cursan el grado de medicina. Se emplea una metodología de estudio tipo cuantitativa con un diseño descriptivo y comparativo. Los resultados indican que los estudiantes de la muestra presentan un grado de satisfacción bastante favorable con la experiencia formativa, siendo el funcionamiento y los recursos didácticos del entorno virtual, así como el perfil del docente, las variables discriminativas mejor valoradas. Asimismo, no existen diferencias significativas (IC 99,95%) por razón del género, de la edad y de las rotaciones realizadas durante las clases no presenciales. En conclusión, los estudiantes universitarios valoran, en general, y de forma muy positiva, la experiencia vivida en esta clase de formación.       &nbsp

    BACKGROUND AND AIMS: TRIM5 and TRIM22 are restriction factors involved in innate immune response and exhibit anti-viral activity. Single nucleotide polymorphisms (SNPs) at TRIM5 and TRIM22 genes have shown to influence several viral infections such as human immunodeficiency virus (HIV), hepatitis B, as well as measles and rubella vaccination. The aim of this study is to analyze whether TRIM5 and TRIM22 polymorphisms are associated with liver fibrosis inflammation-related biomarkers and response to pegylated-interferon-alpha plus ribavirin (pegIFNα/RBV) therapy in HIV/hepatitis C virus (HCV) coinfected patients. METHODS: A retrospective study was performed in 319 patients who started pegIFNα/RBV therapy. Liver fibrosis stage was characterized in 288 patients. TRIM5 rs3824949 and TRIM22 polymorphisms (rs1063303, rs7935564, and rs7113258) were genotyped using the GoldenGate assay. The primary outcomes were: a) significant liver fibrosis (≥F2) evaluated by liver biopsy or transient elastography (liver stiffness values ≥7.1 Kpa); b) sustained virological response (SVR) defined as no detectable HCV viral load (<10 IU/mL) at week 24 after the end of the treatment. The secondary outcome variable was plasma chemokine levels. RESULTS: Patients with TRIM5 rs3824949 GG genotype had higher SVR rate than patients with TRIM5 rs3824949 CC/CG genotypes (p = 0.013), and they had increased odds of achieving SVR (adjusted odds ratio (aOR = 2.58; p = 0.012). Patients with TRIM22 rs1063303 GG genotype had higher proportion of significant liver fibrosis than patients with rs1063303 CC/CG genotypes (p = 0.021), and they had increased odds of having significant hepatic fibrosis (aOR = 2.19; p = 0.034). Patients with TRIM22 rs7113258 AT/AA genotype had higher SVR rate than patients with rs7113258 TT genotypes (p = 0.013), and they had increased odds of achieving SVR (aOR = 1.88; p = 0.041). The TRIM22 haplotype conformed by rs1063303_C and rs7113258_A was more frequent in patients with SVR (p = 0.018) and was significantly associated with achieving SVR (aOR = 2.80; p = 0.013). The TRIM5 rs3824949 GG genotype was significantly associated with higher levels of GRO-α (adjusted arithmetic mean ratio ((aAMR) = 1.40; p = 0.011) and MCP-1 (aAMR = 1.61; p = 0.003). CONCLUSIONS: TRIM5 and TRIM22 SNPs are associated to increased odds of significant liver fibrosis and SVR after pegIFNα/RBV therapy in HIV/HCV coinfected patients. Besides, TRIM5 SNP was associated to higher baseline levels of circulating biomarkers GRO and MCP-1.The authors wish to thank the Spanish National Genotyping Center (CeGen) for providing the genotyping services (http://www.cegen.org).

    To evaluate the impact of hepatitis C virus (HCV) elimination via interferon (IFN)-based therapy on gene expression profiles related to the immune system in HIV/HCV-coinfected patients. We conducted a prospective study in 28 HIV/HCV-coinfected patients receiving IFN-based therapy at baseline (HIV/HCV-b) and week 24 after sustained virological response (HIV/HCV-f). Twenty-seven HIV-monoinfected patients (HIV-mono) were included as a control. RNA-seq analysis was performed on peripheral blood mononuclear cells (PBMCs). Genes with a fold-change (FC) ≥ 1.5 (in either direction) and false discovery rate (FDR) ≤ 0.05 were identified as significantly differentially expressed (SDE). HIV/HCV-b showed six SDE genes compared to HIV-mono group, but no significantly enriched pathways were observed. For HIV/HCV-f vs. HIV/HCV-b, we found 58 SDE genes, 34 upregulated and 24 downregulated in the HIV/HCV-f group. Of these, the most overexpressed were CXCL2, PDCD6IP, ATP5B, IGSF9, RAB26, and CSRNP1, and the most downregulated were IFI44 and IFI44L. These 58 SDE genes revealed two significantly enriched pathways (FDR < 0.05), one linked to Epstein-Barr virus infection and another related to p53 signaling. For HIV/HCV-f vs. HIV-mono group, we found 44 SDE genes that revealed 31 enriched pathways (FDR < 0.05) related to inflammation, cancer/cell cycle alteration, viral and bacterial infection, and comorbidities associated with HIV/HCV-coinfection. Five genes were overrepresented in most pathways (JUN, NFKBIA, PIK3R2, CDC42, and STAT3). HIV/HCV-coinfected patients who eradicated hepatitis C with IFN-based therapy showed profound gene expression changes after achieving sustained virological response. The altered pathways were related to inflammation and liver-related complications, such as non-alcoholic fatty liver disease and hepatocellular carcinoma, underscoring the need for active surveillance for these patients.This study was supported by grants from Instituto de Salud Carlos III (ISCII; Grant Numbers PI20/00474 and PI17/00657 to JB, PI20/00507 and PI17/00903 to JGG, PI18CIII/00020 to AFR, and PI20CIII/00004 and PI17CIII/00003 to SR).

    Interferon lambda 3 (IFNL3, previously called IL-28B) is a cytokine with effects against viral and bacterial pathogens. We aimed to analyze the IFNL3 rs12980275 SNP in patients who underwent major surgery, in order to establish its relationship with susceptibility to septic shock and septic shock-related death in these patients. We performed a case-control study on 376 patients to establish the association between IFNL3 rs12980275 SNP and the susceptibility to develop septic shock. Besides, we performed a longitudinal study among 172 septic shock patients using survival analysis with one censoring point of 28-days mortality. The IFNL3 rs12980275 polymorphism was genotyped by Agena Bioscience's MassARRAY platform. IFNL3 rs12980275 polymorphism was not associated with higher susceptibility to infection and septic shock development. Regarding survival analysis, the Kaplan-Meier analysis showed that patients with IFNL3 rs12980275 AA genotype had higher survival than patients with GG genotype (p = 0.003). The Cox regression analysis adjusted by the most relevant clinical and epidemiological characteristics showed that the GG genotype (recessive model) and the presence of the G allele (additive model) were associated with higher risk of death [adjusted hazard ratio (aHR) = 2.15, p = 0.034; aHR = 1.50, p = 0.030, respectively]. In conclusion, IFNL3 rs12980275 polymorphism was associated with septic shock-related death in patients who underwent major surgery. The A allele was linked to protection, and the G allele was associated with an increased risk of death. This is a first preliminary study that suggests for the first time a role of IFNL3 polymorphisms in the prognosis of septic shock.This work has been supported by grants given by Instituto de Salud Carlos III (grant numbers PI15/01451 to ET), Gerencia de Salud, Consejería de Sanidad, Junta de Castilla y Leon (grant number GRS 463/A/10 and 773/A/13 to ET), and PFIZER (grant number CT25-ESP01-01 to SR).

    Corrigendum to "PBMCs gene expression signature of advanced cirrhosis with high risk for clinically significant portal hypertension in HIV/HCV coinfected patients: A cross-control study" [Biomed. Pharmacother. 159 (2023) 114220]. Biomed Pharmacother. 2023 Apr 27;114803. doi: 10.1016/j.biopha.2023.114803. PMID: 37120412.Background: Patients with advanced cirrhosis are at high risk of developing clinically significant portal hypertension (CSPH). We analyzed the gene expression profile of peripheral blood mononuclear cells (PBMCs) from HIV/HCV coinfected patients to identify a gene expression signature of advanced cirrhosis with high risk for CSPH. Methods: We conducted a cross-sectional study on 68 patients. Liver stiffness measurement (LSM) was used to stratify patients into < 12.5 kPa (no cirrhosis, n = 19), 12.5 - 24.9 kPa (cirrhosis, n = 20), and ≥ 25 kPa (advanced cirrhosis with high risk for CSPH, n = 29). Besides, we further evaluated LSM < 25 kPa (n = 39) vs. ≥ 25 kPa (n = 29). Total RNA was extracted from PBMCs, and poly(A) RNA sequencing was performed. Two significant differentially expressed (SDE) transcripts were validated by quantitative PCR in a different cohort (n = 46). Results: We found 60 SDE transcripts between patients with LSM < 12.5 kPa and ≥ 25 kPa. Partial least squares discriminant analysis showed that those 60 SDE transcripts collectively discriminated LSM ≥ 25 kPa, with an area under the receiver operating characteristic curve (AUROC) of 0.84. Eight genes had an AUROC ≥ 0.75 for LSM ≥ 25 kPa: five were positively associated with LSM values (SCAMP1, ABHD17B, GPR146, GTF2A1, and TMEM64), while three were inversely associated (ZFHX2-AS1, MDK, and STAG3L2). We validated the two SDE transcripts with the highest discrimination capacity in a different cohort, finding significant differences between < 25 kPa and ≥ 25 kPa (MDK (p = 0.006) and STAG3L2 (p = 0.021)). Conclusions: A gene expression signature of 60 transcripts was associated with advanced cirrhosis with high risk for CSPH in HIV/HCV coinfected patients.This study was supported by grants from Instituto de Salud Carlos III (ISCIII; grant numbers CP17CIII/00007 and PI18CIII/00028 to MAJS, PI17/00657 and PI20/00474 to JB, PI17/00903 and PI20/00507 to JGG, PI18CIII/00020 to AFR, and PI17CIII/00003 and PI20CIII/00004 to SR) and Ministerio de Ciencia e Innovación (AEI, PID2021-126781OB-I00 to AFR).

    We carried out a retrospective exploratory study on 173 patients who underwent major surgery and developed septic shock after surgery. Our findings suggest that CEACAM7 rs1001578, rs10409040, and rs889365 polymorphisms could influence septic shock-related death in individuals who underwent major surgery.This work has been supported by grants given by Instituto de Salud Carlos III (grant number PI15/01451 to ET), “Gerencia de Salud, Consejería de Sanidad, Junta de Castilla y Leon” [grant number GRS 463/A/10 and 773/A/13 to ET], and PFIZER [grant number CT25-ESP01-01 to SR].

    Hepatitis C virus (HCV) cure after all-oral direct-acting antiviral (DAA) therapy greatly improves the liver and immune system. We aimed to assess the impact of this HCV clearance on immune system-related markers in plasma and the gene expression profile in human immunodeficiency virus (HIV)/HCV-coinfected patients with advanced cirrhosis. We performed a prospective study on 33 HIV/HCV-coinfected patients at baseline and 36 weeks after the sustained virological response. Gene expression was evaluated by RNA-seq analysis on peripheral blood mononuclear cells (PBMCs) and plasma biomarkers by multiplex immunoassays. We found a decrease in plasma biomarkers (PD1, PDL1, CXCL10, CXCL8, IL12p70, IL10, and TGFβ) and liver disease markers (stiffness measurement (LSM), hepatic venous pressure gradient (HVPG), and transaminases, among others). Furthermore, decreased plasma levels of CXCL8, CXCL10, IL10, and PD1 were associated with reduced LSM values. We also found two upregulated (HAS1 and IRG1) and 15 downregulated (CXCL11, CCL8, CCL7, CCL2, ADARB2, RRAD, MX1, SIGLEC1, IFI44L, IFI44, IFI27, IFI6, IFIT3, IFIT1B, and IFIT1) genes at the end of follow-up, all interferon-stimulated genes (ISGs) grouped into four pathways ("cytokine-cytokine receptor interaction", "viral protein interaction with cytokine and cytokine receptor", "chemokine signaling pathway", and "hepatitis C"). Additionally, the decrease in most of these ISGs was significantly related to reduced LSM and HVPG values. In conclusion, HIV/HCV-coinfected patients with advanced-HCV-related cirrhosis who eradicated HCV following DAA therapy exhibited an improvement in liver disease markers and a significant decrease in plasma biomarkers and gene expression related to antiviral/inflammatory response, particularly in levels of several chemokines and ISGs.This study was supported by grants from Instituto de Salud Carlos III (ISCII; grant numbers PI20/00474 and PI17/00657 to JB, PI20/00507 and PI17/00903 to JGG, PI18CIII/00020 to AF-R, PI18CIII/00028 to MA, and PI20CIII/00004 and PI17CIII/00003 to SR).

    C2-Domain Abscisic Acid-Related Proteins Mediate the Interaction of PYR/PYL/RCAR Abscisic Acid Receptors with the Plasma Membrane and Regulate Abscisic Acid Sensitivity in Arabidopsis

    Full text link
    Supplemental Data: http://www.plantcell.org/content/26/12/4802/suppl/DC1© 2014 American Society of Plant BiologistsMembrane-delimited abscisic acid (ABA) signal transduction plays a critical role in early ABA signaling, but the molecular mechanisms linking core signaling components to the plasma membrane are unclear. We show that transient calcium-dependent interactions of PYR/PYL ABA receptors with membranes are mediated through a 10-member family of C2-domain ABA-related (CAR) proteins in Arabidopsis thaliana. Specifically, we found that PYL4 interacted in an ABA-independent manner with CAR1 in both the plasma membrane and nucleus of plant cells. CAR1 belongs to a plant-specific gene family encoding CAR1 to CAR10 proteins, and bimolecular fluorescence complementation and coimmunoprecipitation assays showed that PYL4-CAR1 as well as other PYR/PYL-CAR pairs interacted in plant cells. The crystal structure of CAR4 was solved, which revealed that, in addition to a classical calcium-dependent lipid binding C2 domain, a specific CAR signature is likely responsible for the interaction with PYR/PYL receptors and their recruitment to phospholipid vesicles. This interaction is relevant for PYR/PYL function and ABA signaling, since different car triple mutants affected in CAR1, CAR4, CAR5, and CAR9 genes showed reduced sensitivity to ABA in seedling establishment and root growth assays. In summary, we identified PYR/PYL-interacting partners that mediate a transient Ca2+-dependent interaction with phospholipid vesicles, which affects PYR/PYL subcellular localization and positively regulates ABA signaling.We thank Joerg Kudla (University of Munster) for kindly providing plasma membrane markers.

    [ES] Objetivo: Describir las características sociodemográficas, clínicas y terapéuticas de las personas con dolor crónico no oncológico, según sexo. Pacientes y método: Estudio transversal en la Unidad del Dolor del Complejo Asistencial Universitario de Salamanca entre marzo y septiembre de 2020. Se realizó un muestreo consecutivo, obteniendo 105 pacientes. Los datos se extrajeron de las historias clínicas (HHCC) para las variables clínicas y un cuestionario realizado ad hoc para las variables demográficas y socioeconómicas. Se realizó un análisis descriptivo de las variables, según sexo. Resultados: La mayoría de los pacientes con dolor crónico son mujeres (61,9 %) de 56 años, españolas, con residencia en Salamanca y con pareja. Su nivel de estudios es medio/bajo y están en situación de desempleo (p = 0,007). No son las principales proveedoras económicas del núcleo familiar (p < 0,00) y sus ingresos son inferiores a 950 euros al mes (p = 0,001). Poseen vivienda y conviven con otras personas. Su principal actividad son labores domésticas o de cuidados (p = 0,008). Padecen dolor musculoesquelético secundario crónico asociado a alteraciones estructurales, con lumbalgia crónica inespecífica como el diagnóstico más frecuente. Tienen más patologías concomitantes que los hombres, siendo la HTA la más frecuente, y los trastornos psiquiátricos más prevalentes en ellas. Están tratadas con analgésicos y bloqueos de nervios periféricos, respondiendo favorablemente. Conclusión: Identificar la mayor frecuencia de mujeres, con su contexto sociodemográfico y clínico específico, refleja la necesidad de abordar el sexo y los roles de género, y así tenerlos en cuenta a la hora de evaluar cómo influyen ambos en la vivencia del dolor crónico y de cómo llevar a cabo la asistencia y el manejo de nuestros pacientes. [EN] Objective: To describe the sociodemographic, clinical and therapeutic characteristics of people with chronic non-oncologic pain, according to sex. Patients and method: Cross-sectional study in the Pain Unit of the Complejo Asistencial Universitario de Salamanca between March and September 2020. Consecutive sampling was performed, obtaining 105 patients. Data were extracted from the medical records (HHCC) for clinical variables and an ad hoc questionnaire for demographic and socioeconomic variables. A descriptive analysis of the variables was performed according to sex. Results: Most of the patients with chronic pain were women (61.9 %) aged 56 years, Spanish, living in Salamanca and with a partner. Their level of education is medium/low and they are unemployed (p = 0.007). They are not the main economic providers of the family nucleus (p < 0.00) and their income is less than 950 euros per month (p = 0.001). They own a house and live with other people. Their main activity is domestic or care work (p = 0.008). They suffer from chronic secondary musculoskeletal pain associated with structural alterations, with non-specific chronic low back pain as the most frequent diagnosis. They have more concomitant pathologies than men, with HT being the most frequent, and psychiatric disorders more prevalent in them. They are treated with analgesics and peripheral nerve blocks, responding favorably. Conclusion: Identifying the higher frequency of women, with their specific sociodemographic and clinical context, reflects the need to address sex and gender roles and thus take them into account when assessing how both influence the experience of chronic pain and how to carry out the care and management of our patients.S
