Increased risk of MAFLD and liver fibrosis in inflammatory bowel disease independent of classic metabolic risk factors

ackground & Aims There is conflicting evidence regarding the prevalence of and risk factors for metabolic-associated fatty liver disease (MAFLD) in patients with inflammatory bowel disease (IBD). We aimed to determine MAFLD prevalence and risk factors in IBD patients. Methods Cross-sectional, case-control study included all consecutive IBD patients treated at 2 different university hospitals. Controls were subjects randomly selected from the general population and matched by age, sex, type 2 diabetes status, and body mass index in a 1:2 ratio. MAFLD was confirmed by controlled attenuation parameter. Liver biopsies were collected when MAFLD with significant liver fibrosis was suspected. In addition, age- and fibrosis stage-paired non-IBD patients with biopsy-proven MAFLD served as a secondary control group. Results Eight hundred thirty-one IBD patients and 1718 controls were included. The prevalence of MAFLD and advanced liver fibrosis (transient elastography ≥9.7 kPa) was 42.00% and 9.50%, respectively, in IBD patients and 32.77% and 2.31%, respectively, in the general population (P < .001). A diagnosis of IBD was an independent predictor of MAFLD (adjusted odds ratio, 1.99; P < .001) and an independent risk factor for advanced liver fibrosis (adjusted odds ratio, 5.55; P < .001). Liver biopsies were obtained from 40 IBD patients; MAFLD was confirmed in all cases, and fibrosis of any degree was confirmed in 25 of 40 cases (62.5%). Body mass index and type 2 diabetes prevalence were significantly lower in IBD-MAFLD patients than in severity-paired patients with biopsy-proven MAFLD. Conclusions MAFLD and liver fibrosis are particularly prevalent in IBD patients, regardless of the influence of classic metabolic risk factors.Acknowledgements: The authors report funding support from the Spanish Instituto de Salud Carlos III-FEDER Grant (FIS - PI18/01304) related to this manuscript

Multicentre, randomised, open-label, phase IV–III study to evaluate the efficacy of cloxacillin plus fosfomycin versus cloxacillin alone in adult patients with methicillin-susceptible Staphylococcus aureus bacteraemia: study protocol for the SAFO trial

SAFO study group and the Spanish Network for Research in Infectious Diseases (REIPI).[Introduction] Methicillin-susceptible Staphylococcus aureus (MSSA) bacteraemia is a frequent condition, with high mortality rates. There is a growing interest in identifying new therapeutic regimens able to reduce therapeutic failure and mortality observed with the standard of care of beta-lactam monotherapy. In vitro and small-scale studies have found synergy between cloxacillin and fosfomycin against S. aureus. Our aim is to test the hypothesis that cloxacillin plus fosfomycin achieves higher treatment success than cloxacillin alone in patients with MSSA bacteraemia.[Methods] We will perform a superiority, randomised, open-label, phase IV–III, two-armed parallel group (1:1) clinical trial at 20 Spanish tertiary hospitals. Adults (≥18 years) with isolation of MSSA from at least one blood culture ≤72 hours before inclusion with evidence of infection, will be randomly allocated to receive either cloxacillin 2 g/4-hour intravenous plus fosfomycin 3 g/6-hour intravenous or cloxacillin 2 g/4-hour intravenous alone for 7 days. After the first week, sequential treatment and total duration of antibiotic therapy will be determined according to clinical criteria by the attending physician. Primary endpoints: (1) Treatment success at day 7, a composite endpoint comprising all the following criteria: patient alive, stable or with improved quick-Sequential Organ Failure Assessment score, afebrile and with negative blood cultures for MSSA at day 7. (2) Treatment success at test of cure (TOC) visit: patient alive and no isolation of MSSA in blood culture or at another sterile site from day 8 until TOC (12 weeks after randomisation). We assume a rate of treatment success of 74% in the cloxacillin group. Accepting alpha risk of 0.05 and beta risk of 0.2 in a two-sided test, 183 subjects will be required in each of the control and experimental groups to obtain statistically significant difference of 12% (considered clinically significant).[Ethics and dissemination] Ethical approval has been obtained from the Ethics Committee of Bellvitge University Hospital (AC069/18) and from the Spanish Medicines and Healthcare Product Regulatory Agency (AEMPS, AC069/18), and is valid for all participating centres under existing Spanish legislation. The results will be presented at international meetings and will be made available to patients and funders.[Trial registration number] The protocol has been approved by AEMPS with the Trial Registration Number EudraCT 2018-001207-37.

Infections after spine instrumentation: effectiveness of short antibiotic treatment in a large multicentre cohort

REIPI (Spanish Network for Research in Infectious Disease)/GEIO–SEIMC (Group for the Study of Osteoarticular Infections – Spanish Society of Infectious Diseases and Clinical Microbiology).[Background and objectives] Available information about infection after spine instrumentation (IASI) and its management are scarce. We aimed to analyse DAIR (debridement, antibiotics and implant retention) prognosis and evaluate effectiveness of short antibiotic courses on early forms.[Methods] Multicentre retrospective study of patients with IASI managed surgically (January 2010–December 2016). Risk factors for failure were analysed by multivariate Cox regression and differences between short and long antibiotic treatment were evaluated with a propensity score-matched analysis.[Results] Of the 411 IASI cases, 300 (73%) presented in the first month after surgery, 48 in the second month, 22 in the third and 41 thereafter. Infections within the first 2 months (early cases) occurred mainly to older patients, with local inflammatory signs and predominance of Enterobacteriaceae, unlike those in the later periods. When managed with DAIR, prognosis of early cases was better than later ones (failure rate 10.4% versus 26.1%, respectively; P = 0.02). Risk factors for DAIR failure in early cases were female sex, Charlson Score, large fusions (>6 levels) and polymicrobial infections (adjusted HRs of 2.4, 1.3, 2.6 and 2.26, respectively). Propensity score matching proved shorter courses of antibiotics (4–6 weeks) as effective as longer courses (failure rates 11.4% and 10.5%, respectively; P = 0.870).[Conclusions] IASIs within the first 2 months could be managed effectively with DAIR and shorter antibiotic courses. Clinicians should be cautious when faced with patients with comorbidities, large fusions and/or polymicrobial infections.E.B. was supported with a grant of the Instituto de Salud Carlos III – Ministry of Science and Innovation (FI 16/00397).

Impacto de la edad del donante-receptor en la supervivencia al trasplante cardiaco. Subanálisis del Registro Español de Trasplante Cardiaco

[Abstract] Introduction and objectives. The age of heart transplant recipients and donors is progressively increasing. It is likely that not all donor-recipient age combinations have the same impact on mortality. The objective of this work was to compare survival in transplant recipients according to donor-recipient age combinations. Methods. We performed a retrospective analysis of transplants performed between 1 January 1993 and 31 December 2017 in the Spanish Heart Transplant Registry. Pediatric transplants, retransplants and combined transplants were excluded (6505 transplants included). Four groups were considered: a) donor < 50 years for recipient < 65 years; b) donor < 50 years for recipient ≥ 65 years; c) donor ≥ 50 years for recipient ≥ 65 years, and d) donor ≥ 50 years for recipient < 65 years. Results. The most frequent group was young donor for young recipient (73%). There were differences in the median survival between the groups (P < .001): a) younger-younger: 12.1 years, 95%CI, 11.5-12.6; b) younger-older: 9.1 years, 95%CI, 8.0-10.5; c) older-older: 7.5 years, 95%CI, 2.8-11.0; d) older-younger: 10.5 years, 95%CI, 9.6-12.1. On multivariate analysis, independent predictors of mortality were the age of the donor and the recipient (0.008 and 0.001, respectively). The worst combinations were older-older vs younger-younger (HR, 1.57; 95%CI, 1.22-2.01; P < .001) and younger-older vs younger-younger (HR, 1.33; 95%CI, 1.12-1.58; P = .001). Conclusions. Age (of the donor and recipient) is a relevant prognostic factor in heart transplant. The donor-recipient age combination has prognostic implications that should be identified when accepting an organ for transplant.[Resumen] Introducción y objetivos. La edad de receptores y donantes cardiacos se está incrementando progresivamente. Es probable que no todas las combinaciones tengan el mismo impacto en la mortalidad. El objetivo de este trabajo es comparar la supervivencia de los pacientes trasplantados según la combinación de edades de donante y receptor. Métodos. Análisis retrospectivo del Registro Español de Trasplante Cardiaco de los trasplantes realizados entre el 1 de enero de 1993 y el 31 de diciembre de 2017. Se excluyeron los pediátricos, los retrasplantes y los trasplantes combinados (se incluyeron 6.505 trasplantes). Se consideraron 4 grupos: a) donante menor de 50 años para receptor menor de 65 años; b) donante menor de 50 años para receptor de edad ≥ 65 años; c) donante de edad ≥ 50 años para receptor de 65 o más, y d) donante de edad ≥ 50 años para receptor menor de 65. Resultados. El grupo más frecuente fue el de donante joven para receptor joven (73%). Hubo diferencias en la mediana de supervivencia entre los grupos (p < 0,001): a) joven-joven: 12,1 años (IC95%, 11,5-12,6); b) joven-mayor: 9,1 años (IC95%, 8,0-10,5); c) mayor-mayor: 7,5 años (IC95%, 2,8-11,0), y d) mayor-joven: 10,5 años (IC95%, 9,6-12,1). En el análisis multivariante, las edades del donante y del receptor resultaron predictoras independientes de la mortalidad (0,008 y 0,001 respectivamente). Las peores combinaciones fueron mayor-mayor frente a joven-joven (HR = 1,57; IC95%, 1,22-2,01; p < 0,001) y joven-mayor frente a joven-joven (HR = 1,33; IC95%, 1,12-1,58; p = 0,001). Conclusiones. La edad (del donante y del receptor) es un factor pronóstico relevante en el trasplante cardiaco. La combinación de edades de donante y receptor posee implicaciones pronósticas que se debe conocer a la hora de aceptar un órgano para trasplante

Entornos digitales y políticas educativas : dilemas y certezas

Recupera los principales aportes del Seminario internacional “Educación y políticas TIC. Los sistemas educativos en contextos de inmersión tecnológica”, organizado por el IIPE-UNESCO Buenos Aires en 2015. El encuentro contó con la presencia de expertos y funcionarios de varios países de América Latina y de España con la intención de producir un ámbito potente para la discusión sobre el impacto de estas tecnologías en relación con la educación en contextos con disposición tecnológica, sus horizontes y fronteras, y también más allá –si fuera posible– de los territorios conocidos. Se convocó a un análisis sobre el tema con posibles orientaciones generales de las políticas TIC desde un enfoque de derechos, atentos a las tensiones que tienen lugar en el encuentro complejo entre la cultura digital y la cultura escolar. En este contexto, esta publicación invita a la reflexión y profundiza sobre el sentido de la inclusión TIC en la educación de América Latina haciendo énfasis en los desafíos que implica para la educación formal en tanto formadora de las nuevas generaciones. También se aborda la inclusión de las TIC en los sistemas educativos como una oportunidad para revisar y actualizar los procesos de enseñanza y de aprendizaje en la búsqueda de una mejora de su calidad. Sin duda estos cambios implican la necesidad de reconfigurar el diseño pedagógico de la escolarización para transformar los viejos paradigmas y poder dar cuenta de las necesidades de niños, niñas y jóvenes que entran en el sistema en contextos de disponibilidad tecnológica pero con deudas educativas. Los documentos aquí reunidos reúnen experiencias que surgen del campo de la investigación por un lado, como también reflexiones y aportes desde la experiencia directa en la gestión de las políticas TIC en Colombia, Costa Rica, Perú, Argentina y Uruguay. Esta experiencia regional en el tema pretende aportar al debate pero también realizar una serie de recomendaciones para todos los países que se encuentran llevando a cabo inclusión de TIC en sus aulas

Association Between Preexisting Versus Newly Identified Atrial Fibrillation and Outcomes of Patients With Acute Pulmonary Embolism

Background Atrial fibrillation (AF) may exist before or occur early in the course of pulmonary embolism (PE). We determined the PE outcomes based on the presence and timing of AF. Methods and Results Using the data from a multicenter PE registry, we identified 3 groups: (1) those with preexisting AF, (2) patients with new AF within 2 days from acute PE (incident AF), and (3) patients without AF. We assessed the 90-day and 1-year risk of mortality and stroke in patients with AF, compared with those without AF (reference group). Among 16 497 patients with PE, 792 had preexisting AF. These patients had increased odds of 90-day all-cause (odds ratio [OR], 2.81; 95% CI, 2.33-3.38) and PE-related mortality (OR, 2.38; 95% CI, 1.37-4.14) and increased 1-year hazard for ischemic stroke (hazard ratio, 5.48; 95% CI, 3.10-9.69) compared with those without AF. After multivariable adjustment, preexisting AF was associated with significantly increased odds of all-cause mortality (OR, 1.91; 95% CI, 1.57-2.32) but not PE-related mortality (OR, 1.50; 95% CI, 0.85-2.66). Among 16 497 patients with PE, 445 developed new incident AF within 2 days of acute PE. Incident AF was associated with increased odds of 90-day all-cause (OR, 2.28; 95% CI, 1.75-2.97) and PE-related (OR, 3.64; 95% CI, 2.01-6.59) mortality but not stroke. Findings were similar in multivariable analyses. Conclusions In patients with acute symptomatic PE, both preexisting AF and incident AF predict adverse clinical outcomes. The type of adverse outcomes may differ depending on the timing of AF onset.info:eu-repo/semantics/publishedVersio

Assessing the potential of solar energy in pressurized irrigation networks. The case of Bembézar MI irrigation district (Spain)

The high energy requirements and the rising costs highlight the need to reduce the energy dependence of the irrigation sector. Alternative management strategies have been developed to reduce the energy consumption of the irrigated areas and to improve the efficiency in the water and energy use. In addition, the renewable energy sources are starting to be considered as an alternative to reduce energy costs with smaller environmental impacts. In this work, a new methodology, that combines sectoring as energy saving measure and solar energy, is developed. Thus, it reduces the energy requirements and the dependence on conventional energy resources. This methodology is applied to the irrigation district of Bembézar Margen Izquierda (Córdoba, Spain). The results show that organizing the network in two irrigation sectors, annual potential energy savings of 30.8% were achieved. Therefore, this measure reduces the annual energy bill in 30.4% without major investments. Then, a 2.1 MW photovoltaic would supply energy to the sector with higher energy consumption. However, conventional energy would be required (with an annual cost of � 33.6 ha�1) when solar energy is not available or it is not enough to supply the demanded flows. Both measures together would reduce the energy costs in 71.7% and the greenhouse gases emissions in 70.5%. The total investment would be Me 2.8 but with a payback period of 8 years. At present, solar energy is a technically and economically viable alternative, which offers both economic and environmental benefit

Efficacy of the therapeutic use of video games on the depressive state of stroke patients: Protocol for systematic review and meta-analysis

Aim To assess the effects of virtual reality (VR) on the depressive state of patients with stroke admitted to neuro-rehabilitation units. Design: Systematic review and meta-analysis protocol. Methods Randomized Controlled Trials (RCTs) focusing on the effects of virtual reality on depressive state as a primary outcome will be included. Grey literature and the following databases will be consulted: PubMed, Cinahl, PsycInfo, Scopus, Embase, Cochrane Library and Web of Science. The recently revised Cochrane risk of bias tool will be used to assess the quality of included studies. Data will be extracted and meta-analyses will be performed within the specific condition of the emotional state of stroke patients admitted to neurorehabilitation units. Meta-regression and subgroup analyses will be used to identify effective modes and patterns of therapy delivery. The approach of assessment, development and evaluation of recommendations will be applied to reach a convincing conclusion. Discussion An accurate, transparent and standardized review process is expected to provide recommendations on the use of VR technology in the healthcare of stroke patients. Impact Emotional difficulties are common after stroke and have an impact on rehabilitation outcome. VR seems to have an important role in the treatment and depression in neurological patients, as it is able to improve levels of well-being, coping strategies and social relationships. The systematic review may contribute to a more convincing and specific conclusion compared to existing studies of this type. Trial registration Systematic review registration: CRD42022303968
