    La importancia  de analizar la problemática de la pobreza y de la violencia intrafamiliar asociadas a la exclusión psicosocial- como precursora de trastornos afectivos- como se propone  la presente investigación  radica en que ambos flagelos  afectan  la integridad de la vida humana y más actualmente, que  el mundo se enfrenta con una crisis económica global. En este estudio  se considera pobreza al “síndrome situacional en el que se asocian el infra consumo, la desnutrición, las precarias condiciones de vivienda, los bajos niveles educacionales, las malas condiciones sanitarias, una inserción inestable en el aparato productivo, actitudes de desaliento y anomia, poca participación en los mecanismos de integración social, y quizá la adscripción a una escala particular de valores, diferenciada en alguna medida de la del resto de la sociedad” y violencia intrafamiliar a  todo tipo de abuso o maltrato físico, psíquico y/o sexual que tenga lugar dentro de la familia o unidad doméstica o en cualquier otra relación interpersonal, ya sea que el agresor comparta o haya compartido el mismo domicilio que la víctima”. El conocimiento empírico permitirá diagnosticar la problemática  real en el gran San Juan para promover medidas reparadoras tanto desde la gestión pública como privada y aún continuar con otras investigacione

    Weak force detection with superposed coherent states

    Get PDF
    We investigate the utility of non classical states of simple harmonic oscillators, particularly a superposition of coherent states, for sensitive force detection. We find that like squeezed states a superposition of coherent states allows displacement measurements at the Heisenberg limit. Entangling many superpositions of coherent states offers a significant advantage over a single mode superposition states with the same mean photon number.Comment: 6 pages, no figures: New section added on entangled resources.

    Introduction: We aimed to evaluate if prior oral anticoagulation (OAC) and its type determines a greater risk of symptomatic hemorrhagic transformation in patients with acute ischemic stroke (AIS) subjected to mechanical thrombectomy. Materials and Methods: Consecutive patients with AIS included in the prospective reperfusion registry NORDICTUS, a network of tertiary stroke centers in Northern Spain, from January 2017 to December 2019 were included. Prior use of oral anticoagulants, baseline variables, and international normalized ratio (INR) on admission were recorded. Symptomatic intracranial hemorrhage (sICH) was the primary outcome measure. Secondary outcome was the relation between INR and sICH, and we evaluated mortality and functional outcome at 3 months by modified Rankin scale. We compared patients with and without previous OAC and also considered the type of oral anticoagulants. Results: About 1.455 AIS patients were included, of whom 274 (19%) were on OAC, 193 (70%) on vitamin K antagonists (VKA), and 81 (30%) on direct oral anticoagulants (DOACs). Anticoagulated patients were older and had more comorbidities. Eighty-one (5.6%) developed sICH, which was more frequent in the VKA group, but not in DOAC group. OAC with VKA emerged as a predictor of sICH in a multivariate regression model (OR, 1.89 [95% CI, 1.01–3.51], p = 0.04) and was not related to INR level on admission. Prior VKA use was not associated with worse outcome in the multivariate regression model nor with mortality at 3 months. Conclusions: OAC with VKA, but not with DOACs, was an independent predictor of sICH after mechanical thrombectomy. This excess risk was associated neither with INR value by the time thrombectomy was performed, nor with a worse functional outcome or mortality at 3 months

    Introducción: El ictus isquémico (II) por disección arterial cervicocerebral (DAC) es una entidad infrecuente y existen pocos datos sobre el uso de terapias de reperfusión como la fibrinólisis intravenosa y la trombectomía mecánica. Se analizó el uso de dichas terapias en pacientes con II por DAC y se comparó con aquellos pacientes reperfundidos con II por otras causas. Método: Estudio observacional retrospectivo multicéntrico de pacientes con II por DAC basado en el Registro Nacional de Ictus de la Sociedad Española de Neurología durante el periodo 2011-2019. Se realizaron análisis comparativos entre: a) pacientes con DAC tratados y no tratados con terapias de reperfusión y b) pacientes reperfundidos con II por DAC y pacientes reperfundidos con II por otras causas. Se incluyeron variables epidemiológicas, del ictus y resultados al alta y a los 3 meses. Resultados: Un total de 21.037 pacientes con II fueron incluidos; 223 (1%) fueron por DAC y 68 (30%) recibieron tratamiento de reperfusión. El uso de tratamientos de reperfusión fue menor en los casos de DAC de arteria vertebral y mayor en los casos de oclusión carotídea. Los pacientes con II por DAC reperfundidos respecto a aquellos con II reperfundidos por otras causas fueron más jóvenes, la trombectomía mecánica se utilizó más y la fibrinólisis intravenosa menos. Las complicaciones hemorrágicas, la mortalidad y la autonomía a los 3 meses fueron similares. Conclusiones: Las terapias de reperfusión se usan con frecuencia en los pacientes con II por DAC. Los resultados demuestran eficacia y seguridad y son equiparables a los pacientes tratados con terapias de reperfusión por II de otras causas.Introduction: Ischaemic stroke (IS) due to cervical and cerebral artery dissection (CAD) is a rare entity, and few data are available on the use of such reperfusion therapies as intravenous fibrinolysis and mechanical thrombectomy in these patients. We analysed the use of these treatments in patients with IS due to CAD and compared them against patients receiving reperfusion treatment for IS of other aetiologies. Method: We conducted an observational, retrospective, multicentre study of patients with IS due to CAD recorded in the National Stroke Registry of the Spanish Society of Neurology during the period 2011-2019. Comparative analyses were performed between: a) patients with CAD treated and not treated with reperfusion therapies and b) patients treated with reperfusion for IS due to CAD and patients treated with reperfusion for IS due to other causes. Epidemiological data, stroke variables, and outcomes at discharge and at 3 months were included in the analysis. Results: The study included 21,037 patients with IS: 223 (1%) had IS due to CAD, of whom 68 (30%) received reperfusion treatment. Reperfusion treatments were used less frequently in cases of vertebral artery dissection and more frequently in patients with carotid artery occlusion. Compared to patients with IS due to other causes, patients with CAD were younger, more frequently underwent mechanicalthrombectomy, and less frequently received intravenous fibri nolysis. Rates of haemorrhagic complications, mortality, and independence at 3 months were similar in both groups. Conclusions: Reperfusion therapy is frequently used in patients with IS due to CAD. The outcomes of these patients demonstrate the efficacy and safety of reperfusion treatments, and are comparable to the outcomes of patients with IS due to other aetiologie

    Get PDF
    In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments. Data were provided by 73,223 participants with varying completion rates. Participants completed the survey from 111 geopolitical regions in 44 unique languages/dialects. The anonymized dataset described here is provided in both raw and processed formats to facilitate re-use and further analyses. The dataset offers secondary analytic opportunities to explore coping, framing, and self-determination across a diverse, global sample obtained at the onset of the COVID-19 pandemic, which can be merged with other time-sampled or geographic data
