    La formación en el afecto, en los valores, en la moral... ¿Qué mejor ámbito para su análisis e incorporación a una práctica social y pedagógica coherente con ello que la vida cotidiana?...la vida cotidiana escolar o familiar, personal o colectiva. Los afectos, y éstos como fundamento de una educación orientada hacia la formación de sujetos históricos, hombres y mujeres con responsabilidad, compromiso y conciencia sociales, corresponden a una de las formas de contacto cotidiano más importantes, especialmente por la intensidad de los sentimientos que en ellas se establecen: nos referimos a las relaciones entre sujetos. Constituyen expresiones suyas, las relaciones de amistad, el amor, pero también el adío. Aunque una valoración de tales sentimientos solo se logra mediante el análisis del contenido y la motivación — sobre todo de orden moral— de tales sentimientos, podemos afirmar, en general, siguiendo a Agnes Heller que el desarrollo de la moral, de la política, del arte y de la ciencia, es inconcebible sin grandes amores y grandes odios’’.Training in affection, in values, in morality... What better environment for its analysis and incorporation into a coherent social and pedagogical practice than daily life?... daily school or family, personal life or collective. Affections, and these as the foundation of an education oriented towards the formation of historical subjects, men and women with social responsibility, commitment and conscience, correspond to one of the most important forms of daily contact, especially due to the intensity of the feelings that in they are established: we refer to the relations between subjects. Their expressions are friendships, love, but also goodbye. Although an assessment of such feelings can only be achieved through analysis of content and motivation — especially of moral order— of such feelings, we can affirm, in general, following Agnes Heller that the development of morality, politics, art and science is inconceivable without great loves and great hates.Modalidad Presencia

Further distribution of this work must maintain attribution to the author(s) and the published articles title, journal citation, and DOI.A search for physics beyond the standard model in events with at least three leptons is presented. The data sample, corresponding to an integrated luminosity of 19.5fb-1 of proton-proton collisions with center-of-mass energy s=8TeV, was collected by the CMS experiment at the LHC during 2012. The data are divided into exclusive categories based on the number of leptons and their flavor, the presence or absence of an opposite-sign, same-flavor lepton pair (OSSF), the invariant mass of the OSSF pair, the presence or absence of a tagged bottom-quark jet, the number of identified hadronically decaying τ leptons, and the magnitude of the missing transverse energy and of the scalar sum of jet transverse momenta. The numbers of observed events are found to be consistent with the expected numbers from standard model processes, and limits are placed on new-physics scenarios that yield multilepton final states. In particular, scenarios that predict Higgs boson production in the context of supersymmetric decay chains are examined. We also place a 95% confidence level upper limit of 1.3% on the branching fraction for the decay of a top quark to a charm quark and a Higgs boson (t→cH), which translates to a bound on the left- and right-handed top-charm flavor-violating Higgs Yukawa couplings, λtcH and λctH, respectively, of |λtcH|2+|λctH|2<0.21

    Background and Aim: The circulating recombinant form 02_AG (CRF02_AG) is the predominant clade among the human immunodeficiency virus type-1 (HIV-1) non-Bs with a prevalence of 5.97% (95% Confidence Interval-CI: 5.41–6.57%) across Spain. Our aim was to estimate the levels of regional clustering for CRF02_AG and the spatiotemporal characteristics of the largest CRF02_AG subepidemic in Spain.Methods: We studied 396 CRF02_AG sequences obtained from HIV-1 diagnosed patients during 2000–2014 from 10 autonomous communities of Spain. Phylogenetic analysis was performed on the 391 CRF02_AG sequences along with all globally sampled CRF02_AG sequences (N = 3,302) as references. Phylodynamic and phylogeographic analysis was performed to the largest CRF02_AG monophyletic cluster by a Bayesian method in BEAST v1.8.0 and by reconstructing ancestral states using the criterion of parsimony in Mesquite v3.4, respectively.Results: The HIV-1 CRF02_AG prevalence differed across Spanish autonomous communities we sampled from (p &lt; 0.001). Phylogenetic analysis revealed that 52.7% of the CRF02_AG sequences formed 56 monophyletic clusters, with a range of 2–79 sequences. The CRF02_AG regional dispersal differed across Spain (p = 0.003), as suggested by monophyletic clustering. For the largest monophyletic cluster (subepidemic) (N = 79), 49.4% of the clustered sequences originated from Madrid, while most sequences (51.9%) had been obtained from men having sex with men (MSM). Molecular clock analysis suggested that the origin (tMRCA) of the CRF02_AG subepidemic was in 2002 (median estimate; 95% Highest Posterior Density-HPD interval: 1999–2004). Additionally, we found significant clustering within the CRF02_AG subepidemic according to the ethnic origin.Conclusion: CRF02_AG has been introduced as a result of multiple introductions in Spain, following regional dispersal in several cases. We showed that CRF02_AG transmissions were mostly due to regional dispersal in Spain. The hot-spot for the largest CRF02_AG regional subepidemic in Spain was in Madrid associated with MSM transmission risk group. The existence of subepidemics suggest that several spillovers occurred from Madrid to other areas. CRF02_AG sequences from Hispanics were clustered in a separate subclade suggesting no linkage between the local and Hispanic subepidemics

    Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

    Background. Invisible violence against women (IVAW) can be understood as the set of attitudes, behaviors, and subtle beliefs that men use to subordinate women and that are culturally accepted. These behaviors can be a risk factor for intimate partner violence (IPV), so it is important to design tools that allow us to detect it early. The aim of this study was to design and psychometrically assess a questionnaire for the detection of invisible violence against women (Q-IVAW). Methodology. A descriptive cross-sectional methodological study carried out in three phases: (1) development of the initial version; (2) pilot study (N = 51); and (3) final validation study (N = 990). The tool’s reliability, validity, and legibility were assessed. To assess reliability, the internal consistency (Cronbach’s α) was analyzed. The validity assessment included an analysis of content, criterion, and construct validity. Results. The EFA revealed that the Q-IVAW was comprised of five factors that explained 55.85% of the total variance found. The Q-IVAW showed very high reliability (α = 0.937), excellent content validity, and good construct validity. The criterion validity analysis showed a moderate correlation between A-IPVAW and Q-IVAW (r = 0.30; p < 0.001). Conclusion. The psychometric assessment of the Q-IVAW yielded good results, which could support the tool’s ability to assess how often women are subjected to inviable violent behaviors by their partners

    Fuentes vivas en el borde: investigación y experiencias colaborativas para la gobernanza de un sur sostenible en Bogotá

    No full text
    Libro digitalEste libro es el resultado de un proceso de investigación de una red tripartita entre Academia, Empresa Pública y Organizaciones Sociales en el marco del proyecto “Territorios del Agua y Redes de Práctica y Aprendizaje para la apropiación social y la gestión colaborativa del borde sur del Distrito Capital” cofinanciado por Colciencias en la convocatoria 569 de 2012. En él se exponen las memorias de las experiencias de investigación colaborativa en torno a los problemáticas que enfrenta la gestión del agua desde la perspectiva de los Acueductos Comunitarios de la ruralidad de Bogotá, que nacen y se consolidan en un contexto de expansión urbana y en una cuenca históricamente importante para el abastecimiento de agua de Bogotá. Este territorio del agua se ve cada vez mas deteriorado por la minería, y la expansión del Relleno de Doña Juna y la urbanización indiscriminada, poniendo en riesgo medios de vida rurales y prácticas que mantienen los ecosistemas asociados a la regulación y producción de agua para los habitantes tanto rurales como urbanos Bogotá. La historia ambiental, urbana y de las organizaciones sociales, así como la acción colectiva y el desarrollo de una multiplicidad de leyes, planes y políticas que se superponen para hacer manejo de este tipo de territorios, muestra la falta de claridad sobre una ruta crítica acordada entre los actores implicados en las dinámicas de este territorio, cuya falta convergencia pone en riesgo no solo a las comunidades locales de las áreas rurales sino la sostenibilidad socio-ecológica de grandes sectores de la ciudad y del territorio en su conjunto. Las fuentes vivas hacen alusión tanto a las fuentes de agua que abastecen los acueductos comunitarios del sur de Bogotá, pero también la a la gente del territorio que vive de estas fuentes. Las fuentes vivas en este libro son autoras de las descripciones, los problemas y los relatos que registramos en este libro, así como de los procesos analíticos y reflexivos y de las acciones colaborativas que se exponen. Dichas fuentes vivas están en el Borde por su doble condición. Primero, de estar en el borde entendido éste como un fenómeno de interface o transición dinámica entre lo urbano y lo rural, regidos por una dinámica de ocupación y uso del territorio que funciona como un todo socio-ambiental, no siempre coherente y cohesivo. En segundo lugar, porque están en el borde entendido éste como referente simbólico de riesgo, de límite, donde podemos vislumbrar una transición que puede tomar el rumbo de la catástrofe o por el contrario ir hacia una salida sostenible. La sostenibilidad, en este caso, depende de la construcción de una consciencia ecológica y ambiental por parte de quienes estamos transformando las dinámicas del agua y de la vida en este territorio. Ello, entre otras, requiere de conocimiento, reflexión y acuerdos para vivir del y con el agua y por lo tanto son las fuentes vivas las que proponen las rutas para la gobernanza del agua. La gobernanza, es en este sentido, el proceso mediante el cual se establece la deliberación y la negociación ente los actores de un territorio dado -en este caso del borde urbano rural del sur de Bogotá - sobre las lógicas que estructuran sus relaciones con los elementos ambientales que usan, apropian, valoran y regulan el agua, a partir de sus prácticas y sus discursos, en contextos de poder, para llegar a acuerdos y tomar decisiones sobre su sostenibilidad.Comité de cartografía: Philippe Chenut -- Javier Rodríguez -- Amparo De Urbina

    CatedresObjectives: We compared the characteristics and clinical outcomes of hospitalized individuals with COVID-19 with [people with HIV (PWH)] and without (non-PWH) HIV co-infection in Spain during the first wave of the pandemic. Methods: This was a retrospective matched cohort study. People with HIV were identified by reviewing clinical records and laboratory registries of 10 922 patients in active-follow-up within the Spanish HIV Research Network (CoRIS) up to 30 June 2020. Each hospitalized PWH was matched with five non-PWH of the same age and sex randomly selected from COVID-19@Spain, a multicentre cohort of 4035 patients hospitalized with confirmed COVID-19. The main outcome was all-cause in-hospital mortality. Results: Forty-five PWH with PCR-confirmed COVID-19 were identified in CoRIS, 21 of whom were hospitalized. A total of 105 age/sex-matched controls were selected from the COVID-19@Spain cohort. The median age in both groups was 53 (Q1-Q3, 46-56) years, and 90.5% were men. In PWH, 19.1% were injecting drug users, 95.2% were on antiretroviral therapy, 94.4% had HIV-RNA < 50 copies/mL, and the median (Q1-Q3) CD4 count was 595 (349-798) cells/μL. No statistically significant differences were found between PWH and non-PWH in number of comorbidities, presenting signs and symptoms, laboratory parameters, radiology findings and severity scores on admission. Corticosteroids were administered to 33.3% and 27.4% of PWH and non-PWH, respectively (P = 0.580). Deaths during admission were documented in two (9.5%) PWH and 12 (11.4%) non-PWH (P = 0.800). Conclusions: Our findings suggest that well-controlled HIV infection does not modify the clinical presentation or worsen clinical outcomes of COVID-19 hospitalization

    The purpose of this study was to assess the prevalence of anti-hepatitis C virus (HCV) antibodies (Abs) and active HCV infection in human immunodeficiency virus (HIV)-infected (HIV+) patients in Spain in 2015. This was a cross-sectional study.Methods. The study was performed in 41 centers in 2015. Sample size was estimated for an accuracy of 2%, the number of patients from each hospital was determined by proportional allocation, and patients were selected using simple random sampling. The reference population was 35 791 patients, and the sample size was 1867 patients. Hepatitis C virus serostatus was known in 1843 patients (98.7%). Hepatitis C virus-Abs were detected in 695 patients (37.7%), in whom the main route of HIV acquisition was injection drug use (75.4%). Of these 695 patients, 402 had HCV RNA, 170 had had a sustained viral response (SVR) after anti-HCV therapy, and 102 cleared HCV spontaneously. Hepatitis C virus-ribonucleic acid results were unknown in 21 cases. Genotype distribution (known in 367 patients) was 1a in 143 patients (39.0%), 4 in 90 (24.5%) patients, 1b in 69 (18.8%) patients, 3 in 57 (15.5%) patients, 2 in 5 (1.4%) patients, and mixed in 3 (0.8%) patients. Liver cirrhosis was present in 93 patients (23.1%) with active HCV infection and in 39 (22.9%) patients with SVR after anti-HCV therapy. The prevalence of HCV-Abs and active HCV infection in HIV+ patients in Spain is 37.7% and 22.1%, respectively; these figures are significantly lower than those recorded in 2002 and 2009. The predominant genotypes in patients with active HCV infection were 1a and 4. A high percentage of patients had cirrhosis. Cirrhosis is also common in patients with SVR after anti-HCV therapy

    Discovering HIV related information by means of association rules and machine learning

    Acquired immunodeficiency syndrome (AIDS) is still one of the main health problems worldwide. It is therefore essential to keep making progress in improving the prognosis and quality of life of affected patients. One way to advance along this pathway is to uncover connections between other disorders associated with HIV/AIDS-so that they can be anticipated and possibly mitigated. We propose to achieve this by using Association Rules (ARs). They allow us to represent the dependencies between a number of diseases and other specific diseases. However, classical techniques systematically generate every AR meeting some minimal conditions on data frequency, hence generating a vast amount of uninteresting ARs, which need to be filtered out. The lack of manually annotated ARs has favored unsupervised filtering, even though they produce limited results. In this paper, we propose a semi-supervised system, able to identify relevant ARs among HIV-related diseases with a minimal amount of annotated training data. Our system has been able to extract a good number of relationships between HIV-related diseases that have been previously detected in the literature but are scattered and are often little known. Furthermore, a number of plausible new relationships have shown up which deserve further investigation by qualified medical experts
