    Cyberattacks threaten continuously computer security in companies. These attacks evolve everyday, being more and more sophisticated and robust. In addition, they take advantage of security breaches in organizations and companies, both public and private. Small and Medium-sized Enterprises (SME), due to their structure and economic characteristics, are particularly damaged when a cyberattack takes place. Although organizations and companies put lots of efforts in implementing security solutions, they are not always effective. This is specially relevant for SMEs, which do not have enough economic resources to introduce such solutions. Thus, there is a need of providing SMEs with affordable, intelligent security systems with the ability of detecting and recovering from the most detrimental attacks. In this paper, we propose an intelligent cybersecurity platform, which has been designed with the objective of helping SMEs to make their systems and network more secure. The aim of this platform is to provide a solution optimizing detection and recovery from attacks. To do this, we propose the application of proactive security techniques in combination with both Machine Learning (ML) and blockchain. Our proposal is enclosed in the IASEC project, which allows providing security in each of the phases of an attack. Like this, we help SMEs in prevention, avoiding systems and network from being attacked; detection, identifying when there is something potentially harmful for the systems; containment, trying to stop the effects of an attack; and response, helping to recover the systems to a normal state

    Neuroprotective and anti-inflammatory effects of linoleic acid in models of parkinson’s disease: the implication of lipid droplets and lipophagy

    Get PDF
    Parkinson’s disease (PD) is the second most prevalent neurodegenerative disease after Alzheimer’s disease. The principal pathological feature of PD is the progressive loss of dopaminergic neurons in the ventral midbrain. This pathology involves several cellular alterations: oxidative stress, mitochondrial dysfunction, loss of proteostasis, and autophagy impairment. Moreover, in recent years, lipid metabolism alterations have become relevant in PD pathogeny. The modification of lipid metabolism has become a possible way to treat the disease. Because of this, we analyzed the effect and possible mechanism of action of linoleic acid (LA) on an SH-SY5Y PD cell line model and a PD mouse model, both induced by 6-hydroxydopamine (6-OHDA) treatment. The results show that LA acts as a potent neuroprotective and anti-inflammatory agent in these PD models. We also observed that LA stimulates the biogenesis of lipid droplets and improves the autophagy/lipophagy flux, which resulted in an antioxidant effect in the in vitro PD model. In summary, we confirmed the neuroprotective effect of LA in vitro and in vivo against PD. We also obtained some clues about the novel neuroprotective mechanism of LA against PD through the regulation of lipid droplet dynamics.This research was supported by the Health Institute “Carlos III”-CIBERNED (CB06/05/0041 and 2015/03), “MINECO” (SAF2014-52940-R, SAF2017-85199-P and SAF 2016-78666-R), “Comunidadde Madrid” (PEJ-2019-AI/SAL-12877), “Erasmus+ funding programme”, UCM-Santander (PR44/21-29931 to J.A.M.-G.), and partially supported by “Fondo Europeo de Desarrollo Regional” (FEDER) from the European Union

    (1) Background: To assess the prevalence of mental disorders (depression and anxiety), psychological distress, and psychiatric medications consumption among persons suffering from COPD; to compare this prevalence with non-COPD controls and to identify which variables are associated with worse mental health. (2) Methods: This is an epidemiological case-control study. The data were obtained from the Spanish National Health Survey 2017. Subjects were classified as COPD if they reported suffering from COPD and the diagnosis of this condition had been confirmed by a physician. For each case, we selected a non-COPD control matched by sex, age, and province of residence. Conditional logistic regression was used for multivariable analysis. (3) Results: The prevalence of mental disorders (33.9% vs. 17.1%; p < 0.001), psychological distress (35.4% vs. 18.2%; p < 0.001), and psychiatric medications consumption (34.1% vs. 21.9%; p < 0.001) was higher among COPD cases compared with non-COPD controls. After controlling for possible confounding variables, such as comorbid conditions and lifestyles, using multivariable regression, the probability of reporting mental disorders (OR 1.41; 95% CI 1.10–1.82).), psychological distress (OR 1.48; 95% CI 1.12–1.91), and psychiatric medications consumption (OR 1.38 95% CI 1.11–1.71) remained associated with COPD. Among COPD cases, being a woman, poor self-perceived health, more use of health services, and active smoking increased the probability of suffering from mental disorders, psychological distress, and psychiatric medication use. Stroke and chronic pain were the comorbidities more strongly associated with these mental health variables. (4) Conclusions: COPD patients have worse mental health and higher psychological distress and consume more psychiatric medications than non-COPD matched controls. Variables associated with poorer mental health included being a woman, poor self-perceived health, use of health services, and active smoking

    Background and Purpose. Intravenous thrombolysis using tissue plasminogen activator is safe and probably effective in patients >80 years old. Nevertheless, its safety has not been specifically addressed for the oldest old patients (≥85 years old, OO). We assessed the safety and effectiveness of thrombolysis in this group of age. Methods. A prospective registry of patients treated with intravenous thrombolysis. Patients were divided in two groups (<85 years and the OO). Demographic data, stroke aetiology and baseline National Institute Health Stroke Scale (NIHSS) score were recorded. The primary outcome measures were the percentage of symptomatic intracranial haemorrhage (SICH) and functional outcome at 3 months (modified Rankin Scale, mRS). Results. A total of 1,505 patients were registered. 106 patients were OO [median 88, range 85–101]. Female sex, hypertension, elevated blood pressure at admission, cardioembolic strokes and higher basal NIHSS score were more frequent in the OO. SICH transformation rates were similar (3.1% versus 3.7%, P = 1.00). The probability of independence at 3 months (mRS 0–2) was lower in the OO (40.2% versus 58.7%, P = 0.001) but not after adjustment for confounding factors (adjusted OR, 0.82; 95% CI, 0.50 to 1.37; P = 0.455). Three-month mortality was higher in the OO (28.0% versus 11.5%,P < 0.001). Conclusion. Intravenous thrombolysis for stroke in OO patients did not increase the risk of SICH although mortality was higher in this groupThis work is part of the Spanish collaborative research network RENEVAS (Instituto de Salud Carlos III, Ministerio de Ciencia e Innovación, RD06/0026/008, RD07/0026/2003

    Communication is one of the most important predictors of social reintegration after stroke. Approximately 15–42% of stroke survivors experience post-stroke aphasia. Helping people recover from aphasia is one of the research priorities after a stroke. Our aim is to develop and validate a new therapy integrating dubbing techniques to improve functional communication. Methods: The research project is structured as three work packages (WP). WP1: development of the dubbed language cinema-based therapy: Two research assistants (a speech therapist and a dubbing actor) will select the clips, mute specific words/sentences in progressive speech difficulty, and guide patients to dub them across sessions. Words to be dubbed will be those considered to be functionally meaningful by a representative sample of aphasic patients and relatives through an online survey. WP2: a randomized, crossover, interventional pilot study with the inclusion of 54 patients with post-stroke non-fluent aphasia. Patients will be treated individually in 40-min sessions twice per week for 8 weeks. Primary outcomes will be significant pre/post differences in scores in the Communicative Activity Log (CAL) questionnaire and Boston Diagnostic Aphasia Examination (BDAE) administered by a psychologist blinded to the patients’ clinical characteristics. Secondary outcomes: General Health Questionnaire (GHQ)-12, Stroke Aphasia Quality of Life Scale (SAQOL-39), Western Aphasia Battery Revised (WAB-R), and the Stroke Aphasic Depression Questionnaire (SADQ10). WP3: educational activities and dissemination of results. WP3 includes educational activities to improve public knowledge of aphasia and dissemination of the results, with the participation of the Spanish patients’ association Afasia Activa. Discussion: This pilot clinical trial will explore the efficacy of a new therapeutic tool based on dubbing techniques and computer technology to improve functional communication of patients suffering from post-stroke aphasia with the use of standardized test assessmentThis study is promoted by Blanca Fuentes and the Research Foundation of La Paz University Hospital, which hosts a research consortium joined by the Department of Neurology at La Paz University Hospital, the Department of Psychology at Comillas Pontifical University, and the patients’ association Afasia Activa. This project has received funding from “la Caixa” Banking Foundation under the project code HR18-00026. Funder is not involved in any of the following processes: design of the trial, data collection, analysis, or interpretation of data nor than in writing the manuscrip

    Características clínicas, terapéuticas y evolutivas de los pacientes con insuficiencia cardiaca aguda atendidos en servicios de urgencias españoles: Registro EAHFE (Epidemiology of Acute Heart Failure in Spanish Emergency Departments)

    Objetivos. Presentación de los resultados del Registro EAHFE (Epidemiology of Acute Heart Failure in Emergency Departments) que recoge las características clínicas, de laboratorio, terapéuticas y la evolución de los pacientes con insuficiencia cardiaca aguda (ICA) atendidos en 29 servicios de urgencias hospitalarios (SUH) españoles. Se analizan los cambios de manejo a lo largo del tiempo; y se comparan los resultados con los de otros registros de ICA. Material y métodos. Estudio multicéntrico, de cohortes, prospectivo, de inclusión consecutiva, realizado en tres periodos (2007, 2009 y 2011). Se recogieron datos demográficos, clínicos, de laboratorio, del tratamiento farmacológico previo y el administrado en SUH y variables evolutivas (mortalidad intrahospitalaria y a los 30 días y al año, reingreso a 30 días). Se analizaron los cambios terapéuticos y evolutivos a lo largo de estos 3 periodos. Se revisó la literatura para identificar registros previos de ICA de carácter nacional o internacional. Resultados. Se incluyeron 5.845 pacientes (2007: 948, 2009: 1.483, 2011: 3.414), con edad media de 79 años y 56% mujeres. Un 34,6% era un primer episodio de ICA. Presentaron elevada comorbilidad (82% hipertensión, 42,3% diabetes mellitus, 47,7% fibrilación auricular). Un 21,9% tenía dependencia funcional grave o total. El 57,3% tenía una disfunción sistólica (FEVI 38,3%). Los principales tratamientos administrados en urgencias consistieron en diuréticos (96,8%), nitroglicerina endovenosa (20,7%), ventilación no invasiva (6,4%) y fármacos inotrópicos o vasopresores (3,6%). El 57% presentaba una tasa de filtrado glomerular disminuida. Las troponinas y los péptidos natriuréticos se determinaron en urgencias en un 49,1% y 42,4% de casos, respectivamente. Las formas de presentación se clasificaron como: normotensiva (66,4%), hipertensiva (23,5%), hipotensiva (4,6%, 0,7% con shock). El 76,1% fue ingresado (1,9% en intensivos), con una mediana de estancia hospitalaria de 7 días, y el 23,9% dado de alta desde urgencias. La mortalidad intrahospitalaria fue 7,6%, a 30 días 9,4% y al año 29,5%. A lo largo del periodo estudiado, ha aumentado la solicitud de troponinas (p < 0,001) y péptidos natriuréticos (p < 0,001) en urgencias, ha disminuido el uso de diuréticos en perfusión (p < 0,001) y de inotropos/vasoconstrictores (p < 0,001) y ha disminuido el porcentaje de reconsulta a 30 días (p = 0,004). No se observaron cambios en la mortalidad intrahospitalaria y a los 30 días entre el periodo 2007-2011. Se han revisado 14 registros anteriores (8 prospectivos), y solo en 2 la inclusión de pacientes se hizo desde el SUH. Conclusiones. El Registro EAHFE describe las características de la ICA a partir de una cohorte que se aproxima al universo de pacientes con ICA. Con el paso del tiempo se observan cambios significativos en el manejo de la ICA: las revisitas han disminuido aunque la mortalidad no se ha modificado. Aparte del Registro EAHFE, solo existen otros 2 registros en el mundo que incluyan a los pacientes con ICA atendidos en urgencias

    (1) Background: Little is known about the effects of SARS-CoV-2 on the placenta, and whether the maternal inflammatory response is transmitted vertically. This research aims to provide information about the effects of SARS-CoV-2 infection on maternal and fetal immunity. (2) Methods: We have studied placental changes and humoral and cellular immunity in maternal and umbilical cord blood (UCB) samples from a group of pregnant women delivering after the diagnosis of SARS-CoV-2 infection during pregnancy. IgG and IgM SARS-CoV-2 antibodies, Interleukin 1b (IL1b), Interleukin 6 (IL6), and gamma-Interferon (IFN-γ), have been studied in the UCB samples. Lymphocyte subsets were studied according to CD3, CD8, CD4, CD34, and invariant natural Killer T cells (iNKT) markers. We used in situ hybridization techniques for the detection of viral RNA in placentas. (3) Results: During the study period, 79 pregnant women and their corresponding newborns were recruited. The main gestational age at the time of delivery was 39.1 weeks (SD 1.3). We did not find traces of the SARS-CoV-2 virus RNA in any of the analyzed placental samples. Detectable concentrations of IgG anti-SARS-CoV-2 antibodies, IL1b, IL6, and IFN-γ, in UCB were found in all cases, but IgM antibodies anti-ARS-CoV-2 were systematically undetectable. We found significant correlations between fetal CD3+ mononuclear cells and UCB IgG concentrations. We also found significant correlations between UCB IgG concentrations and fetal CD3+/CD4+, as well as CD3+/CD8+ T cells subsets. We also discovered that fetal CD3+/CD8+ cell counts were significantly higher in those cases with placental infarctions. (4) Conclusion: we have not verified the placental transfer of SARS-CoV-2. However, we have discovered that a significant immune response is being transmitted to the fetus in cases of SARS-CoV-2 maternal infection.Partial funding for open access charge: Universidad de Málaga.

    12 páginas, 7 figuras, 1 tablaLung ultrasound (LUS) allows for the detection of a series of manifestations of COVID-19, such as B-lines and consolidations. The objective of this work was to study the inter-rater reliability (IRR) when detecting signs associated with COVID-19 in the LUS, as well as the performance of the test in a longitudinal or transverse orientation. Thirty-three physicians with advanced experience in LUS independently evaluated ultrasound videos previously acquired using the ULTRACOV system on 20 patients with confirmed COVID-19. For each patient, 24 videos of 3 s were acquired (using 12 positions with the probe in longitudinal and transverse orientations). The physicians had no information about the patients or other previous evaluations. The score assigned to each acquisition followed the convention applied in previous studies. A substantial IRR was found in the cases of normal LUS (κ = 0.74), with only a fair IRR for the presence of individual B-lines (κ = 0.36) and for confluent B-lines occupying 50% (κ = 0.50). No statistically significant differences between the longitudinal and transverse scans were found. The IRR for LUS of COVID-19 patients may benefit from more standardized clinical protocols.This research was partially funded by CDTI (Spanish acronym: Centre for Industrial Tech- nological Development), funding number COI-20201153.

    El proceso penal del siglo XXI, Quo vadis iustitia?

    Actas de la Jornada "EL PROCESO PENAL DEL SIGLO XXI: QUO VADIS IUSTITIA?", celebrada en la Facultad de Derecho de Jerez de la Frontera, de la Universidad de Cádiz, el 24 de Abril de 2015.Quo vadis iustitia? La pregunta persigue que tanta reforma como se persigue se detenga un momento para responder y, con ello, para pensar sobre el modelo de justicia que se está diseñando. Ya han sido muchas las voces que han hablado de la legislación “galopante” o “motorizada”, o que han usado variados calificativos para referirse al frenesí en la productividad de nuestras cámaras legislativas. Si esto es algo que puede llegar a provocar inseguridad jurídica, debemos pensar que, cuando de lo que se trata es de las normas que afectan a la justicia (orgánicas y procesales) lo que se puede llegar a provocar es una alteración en el equilibrio de los poderes del Estado. No se puede dejar de lado que el funcionamiento de la justicia tiene que ver con uno de los poderes del Estado, el cual, precisamente, debe constituir el fiel que refleje el equilibrio entre los demás, aunque Montesquieu ya no esté muy de moda. La jornada s centra en algunos aspectos de la reforma del proceso penal.Área de Derecho Procesal, Facultad de Derecho Universidad de Cádiz Casa de Iberoamérica (Ayunatmiento de Cádiz) Gestiona: FUECA Proyecto Investigación MINECO DER 2011-26954Documento PDF con 232 páginas
