    Introducción: Es cada vez más extendida la conceptualización de la psicosis en términos de continuum. Las variaciones o vulnerabilidades dentro de este continuo se relaciona con la vulnerabilidad genética o familiar compartida. El objetivo general de esta tesis es el estudio del fenotipo de psicosis en población general (control), población con riesgo genético (hermanos no afectos de pacientes con esquizofrenia) y población clínica (pacientes con diagnóstico de esquizofrenia) y el efecto de distintos factores ambientales sobre el mismo Métodos: Se estudió una muestra de 1167 pacientes, 1181 hermanos y 1042 controles. Se evaluaron los síntomas psicóticos atenuados (SPAs; CAPE), esquizotípicos (SIS-R) y se generó adhoc una escala para valorar el fenotipo psicótico (CS). También se evaluaron factores ambientales de riesgo (trauma, acoso escolar, consumo de cannabis y acontecimientos ambientales estresantes) en todos los sujetos. Se realizaron análisis de correlación, contrastes por grupos y regresiones lineales múltiples controlando por edad y sexo. Se realizaron regresiones múltiples anidadas para explorar el efecto sumativo de las variables de riesgo sobre el fenotipo de la psicosis en cada uno de los grupos por separado y para la muestra en su conjunto. Resultados: Los hermanos de pacientes con esquizofrenia presentan significativamente menos SPAs y síntomas de esquizotipia que los pacientes y significativamente más que los controles y a su vez más prevalencia de factores de riesgo que los controles y significativamente menos que los pacientes con esquizofrenia. La presencia de estos factores de riesgo en hermanos tuvo un efecto significativo en la CS siendo ésta superior a la de los hermanos no expuestos y los controles expuestos y, en ocasiones, similar o superior a la de los pacientes no expuestos. En el caso del consumo de cannabis no se ha observado este efecto. En pacientes, el abuso en la infancia explicó el mayor porcentaje de la varianza de la CS, mientras que en hermanos la presencia de acontecimientos amenazantes actuales y el consumo de cannabis contribuyeron a la misma (aunque de manera prácticamente imperceptible). En controles únicamente la presencia de eventos amenazantes actuales supuso un aporte significativo a la varianza de la CS. Conclusión: Parece evidenciarse la existencia de un fenotipo intermedio (hermanos) entre los pacientes con esquizofrenia y los controles sanos. La presencia de factores de riesgo en hermanos asemeja la expresión del fenotipo psicótico de éstos a la de los pacientes y se diferencia de la de los hermanos no expuestos y los controles. El consumo de cannabis, no aporta de forma relevante a la variabilidad del fenotipo psicótico en ninguno de los grupos estudiados

    La alta prevalencia de suicidio en población adolescente en todo el mundo supone un reto mundial en salud mental. El ambiente familiar ha sido señalado como una importante variable implicada en el riesgo de suicidio de los adolescentes, ejerciendo tanto de factor de riesgo como protector. El estudio tiene como objetivo entender qué variables del funcionamiento familiar de la Escala de Clima Social en la Familia se relacionan con la puntuación de la Escala de Ideación Suicida de Beck en una muestra 37 adolescentes entre 14 y 18 años (M = 15.76; DT = 1.07) con rasgos de personalidad límite. Se partió de la hipótesis de que peores niveles de funcionamiento familiar aumentarían el riesgo de suicidio. Los resultados mostraron que la ideación suicida era mayor cuando las puntuaciones en la escala Relaciones (calidad de la comunicación e interacción) en la familia eran menores. Al analizar cada escala, se demostró la importancia específica de la subescala Expresividad, referida al grado de expresión libre de los sentimientos en la familia de forma que, a menor expresividad en la familia, mayor ideación suicida presentaban los adolescentes, y la subescala Social-Recreativa, referida a la participación social y en actividades de ocio de la familia, de modo que a mayor participación social, menor riesgo suicida. Estos resultados son apoyados por otros estudios que demuestran la importancia de modificar el entorno familiar para influir en el riesgo suicida de los adolescentes. El valor de estos datos implica la consideración de incluir a las familias en los programas de tratamiento para adolescentes suicidas.Family functioning in suicidal adolescents with borderline personality traits. High prevalence of suicide in adolescent population all over the world is considered a world challenge in mental health. Family environment has been pointed as an important factor involved in adolescents’ suicide risk, playing a role not only as a risk factor but also as protective. This study has its goal on understanding which factors of the family functioning, measured by the Social Environment in the Family Scale, are related to the total score of the Beck Suicide Ideation Scale in a sample of 37 adolescents with ages between 14 and 17 years old (M = 15.76; SD = 1.06) borderline personality traits. It was hypothesized that worse levels of family functioning will increase suicide risk in adolescents. Results showed that the risk of suicide was higher when the Relationships Scale total score (quality of communication and interaction in the family) was lower. After analyzing each subscale separately, it was demonstrated the specific relevance of Expressivity Subscale, referred to the level of free expression of feelings in the family, suggesting that the lower expressivity in the family, the higher suicide ideation showed by the adolescents, and Social-Recreative, referred to the social participation and leisure of the family, what means the more social participation, the less suicide ideation. These results are supported by other studies that show the relevance of modifying the family environment for reducing the suicidal risk among adolescents. The value of this data involves taking into account the families in the treatment programs for suicidal adolescents

    Objective: To assess the efficacy and safety of tocilizumab (TCZ) in Caucasian patients with refractory Takayasu's arteritis (TAK) in clinical practice. Methods: A multicenter study of Caucasian patients with refractory TAK who received TCZ. The outcome variables were remission, glucocorticoid-sparing effect, improvement in imaging techniques, and adverse events. A comparative study between patients who received TCZ as monotherapy (TCZMONO) and combined with conventional disease modifying anti-rheumatic drugs (cDMARDs) (TCZCOMBO) was performed. Results: The study comprised 54 patients (46 women/8 men) with a median [interquartile range (IQR)] age of 42.0 (32.5-50.5) years. TCZ was started after a median (IQR) of 12.0 (3.0-31.5) months since TAK diagnosis. Remission was achieved in 12/54 (22.2%), 19/49 (38.8%), 23/44 (52.3%), and 27/36 (75%) patients at 1, 3, 6, and 12 months, respectively. The prednisone dose was reduced from 30.0 mg/day (12.5-50.0) to 5.0 (0.0-5.6) mg/day at 12 months. An improvement in imaging findings was reported in 28 (73.7%) patients after a median (IQR) of 9.0 (6.0-14.0) months. Twenty-three (42.6%) patients were on TCZMONO and 31 (57.4%) on TCZCOMBO: MTX (n = 28), cyclosporine A (n = 2), azathioprine (n = 1). Patients on TCZCOMBO were younger [38.0 (27.0-46.0) versus 45.0 (38.0-57.0)] years; difference (diff) [95% confidence interval (CI) = -7.0 (-17.9, -0.56] with a trend to longer TAK duration [21.0 (6.0-38.0) versus 6.0 (1.0-23.0)] months; diff 95% CI = 15 (-8.9, 35.5), and higher c-reactive protein [2.4 (0.7-5.6) versus 1.3 (0.3-3.3)] mg/dl; diff 95% CI = 1.1 (-0.26, 2.99). Despite these differences, similar outcomes were observed in both groups (log rank p = 0.862). Relevant adverse events were reported in six (11.1%) patients, but only three developed severe events that required TCZ withdrawal. Conclusion: TCZ in monotherapy, or combined with cDMARDs, is effective and safe in patients with refractory TAK of Caucasian origin.Funding: This work was partially supported by RETICS Programs, RD08/0075 (RIER), RD12/0009/0013 and RD16/0012 from “Instituto de Salud Carlos III” (ISCIII) (Spain)

    The main objective of the present study was to investigate the association between several epigenetic clocks, covering different aspects of aging, with schizophrenia relapse evaluated over a 3-year follow-up period in a cohort of ninety-one first-episode schizophrenia patients. Genome-wide DNA methylation was profiled and four epigenetic clocks, including epigenetic clocks of chronological age, mortality and telomere length were calculated. Patients that relapsed during the follow-up showed epigenetic acceleration of the telomere length clock (p = 0.030). Shorter telomere length was associated with cognitive performance (working memory, r = 0.31 p = 0.015; verbal fluency, r = 0.28 p = 0.028), but no direct effect of cognitive function or symptom severity on relapse was detected. The results of the present study suggest that epigenetic age acceleration could be involved in the clinical course of schizophrenia and could be a useful marker of relapse when measured in remission stages

    Effectiveness of family metacognitive training in mothers with psychosis and their adolescent children: a multicenter study protocol

    Get PDF
    BackgroundMore than half of women with psychosis take care of their children despite the difficulties caused by the disease. Additionally, these kids have a higher risk of developing a mental health disorder. However, no interventions have been developed to meet these needs. Metacognitive Training (MCT) is a psychological intervention that has demonstrated its efficacy in improving cognitive insight, symptom management and social cognition in people with first-episode psychosis (FEP). Additionally, MCT has shown better results in women than men with FEP. This study aims to adapt and evaluate the efficacy of MCT-F in mothers and adolescent children in an online group context with the main purpose of improving family relationships, cognitive awareness and symptoms in women with psychosis and increase their children’s knowledge of the disease and their functioning. As secondary objectives, it also aims to evaluate improvements in metacognition, social cognition, symptoms, protective factors and self-perception of stigma.Materials and methodsA quasi-experimental design with participants acting as their own control will be carried out. Forty-eight mothers with psychosis and their adolescent children (between 12 and 20 years old) recruited from a total of 11 adult mental health care centers will receive MCT-F. Participants will be evaluated 11 weeks before the intervention (T1), at baseline (T2), and post-intervention (T3) with a cognitive insight scale, as a primary outcome. Measures of metacognitive and social cognition, symptoms, cognitive functioning, family and social functioning, protective factors (self-esteem, resilience, and coping strategies) and self-perceived stigma will be addressed as secondary outcomes. Assessment will also address trauma and attachment in mothers and, lastly, the feasibility and acceptability of MCT-F in both participant groups.DiscussionThis will be the first investigation of the efficacy, acceptability, and viability of the implementation of MCT-F. The results of this study may have clinical implications, contributing to improving mothers’ with psychosis and adolescents’ functioning and better understanding of the disease, in addition to the possible protective and preventive effect in adolescents, who are known to be at higher risk of developing severe mental disorders.Clinical trial registration:https://clinicaltrials.gov/, identifier [NCT05358457]

    Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

    Get PDF
    Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

    Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

    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

    ObjectivesCARB-ES-19 is a comprehensive, multicenter, nationwide study integrating whole-genome sequencing (WGS) in the surveillance of carbapenemase-producing K. pneumoniae (CP-Kpn) and E. coli (CP-Eco) to determine their incidence, geographical distribution, phylogeny, and resistance mechanisms in Spain.MethodsIn total, 71 hospitals, representing all 50 Spanish provinces, collected the first 10 isolates per hospital (February to May 2019); CPE isolates were first identified according to EUCAST (meropenem MIC &gt; 0.12 mg/L with immunochromatography, colorimetric tests, carbapenem inactivation, or carbapenem hydrolysis with MALDI-TOF). Prevalence and incidence were calculated according to population denominators. Antibiotic susceptibility testing was performed using the microdilution method (EUCAST). All 403 isolates collected were sequenced for high-resolution single-nucleotide polymorphism (SNP) typing, core genome multilocus sequence typing (cgMLST), and resistome analysis.ResultsIn total, 377 (93.5%) CP-Kpn and 26 (6.5%) CP-Eco isolates were collected from 62 (87.3%) hospitals in 46 (92%) provinces. CP-Kpn was more prevalent in the blood (5.8%, 50/853) than in the urine (1.4%, 201/14,464). The cumulative incidence for both CP-Kpn and CP-Eco was 0.05 per 100 admitted patients. The main carbapenemase genes identified in CP-Kpn were blaOXA–48 (263/377), blaKPC–3 (62/377), blaVIM–1 (28/377), and blaNDM–1 (12/377). All isolates were susceptible to at least two antibiotics. Interregional dissemination of eight high-risk CP-Kpn clones was detected, mainly ST307/OXA-48 (16.4%), ST11/OXA-48 (16.4%), and ST512-ST258/KPC (13.8%). ST512/KPC and ST15/OXA-48 were the most frequent bacteremia-causative clones. The average number of acquired resistance genes was higher in CP-Kpn (7.9) than in CP-Eco (5.5).ConclusionThis study serves as a first step toward WGS integration in the surveillance of carbapenemase-producing Enterobacterales in Spain. We detected important epidemiological changes, including increased CP-Kpn and CP-Eco prevalence and incidence compared to previous studies, wide interregional dissemination, and increased dissemination of high-risk clones, such as ST307/OXA-48 and ST512/KPC-3
