Weak force detection with superposed coherent states
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.

Comparación de distintas estrategias para la predicción de muerte a corto plazo en el paciente anciano infectado
Objective. The aim of this study was to determine the utility of a post hoc lactate added to SIRS and qSOFA score to predict 30-day mortality in older non-severely dependent patients attended for infection in the Emergency Department (ED).
Methods. We performed an analytical, observational, prospective cohort study including patients of 75 years of age or older, without severe functional dependence, attended for an infectious disease in 69 Spanish ED for 2-day three seasonal periods. Demographic, clinical and analytical data were collected. The primary outcome was 30-day mortality after the index event.
Results. We included 739 patients with a mean age of 84.9 (SD 6.0) years; 375 (50.7%) were women. Ninety-one (12.3%) died within 30 days. The AUC was 0.637 (IC 95% 0.587-0.688; p= 2 and 0.698 (IC 95% 0.635- 0.761; p= 2. Comparing receiver operating characteristic (ROC) there was a better accuracy of qSOFA vs SIRS (p=0.041). Both scales improve the prognosis accuracy with lactate inclusion. The AUC was 0.705 (IC95% 0.652-0.758; p<0.001) for SIRS plus lactate and 0.755 (IC95% 0.696-0.814; p<0.001) for qSOFA plus lactate, showing a trend to statistical significance for the second strategy (p=0.0727). Charlson index not added prognosis accuracy to SIRS (p=0.2269) or qSOFA (p=0.2573).
Conclusions. Lactate added to SIRS and qSOFA score improve the accuracy of SIRS and qSOFA to predict short-term mortality in older non-severely dependent patients attended for infection. There is not effect in adding Charlson index
Actas de las V Jornadas ScienCity 2022. Fomento de la Cultura Científica, Tecnológica y de Innovación en Ciudades Inteligentes
ScienCity es una actividad que viene siendo continuada desde 2018 con el objetivo de dar a conocer los conocimientos y tecnologías emergentes siendo investigados en las universidades, informar de experiencias, servicios e iniciativas puestas ya en marcha por instituciones y empresas, llegar hasta decisores políticos que podrían crear sinergias, incentivar la creación de ideas y posibilidades de desarrollo conjuntas, implicar y provocar la participación ciudadana, así como gestar una red internacional multidisciplinar de investigadores que garantice la continuación de futuras ediciones. En 2022 se recibieron un total de 48 trabajos repartidos en 25 ponencias y 24 pósteres pertenecientes a 98 autores de 14 instituciones distintas de España, Portugal, Polonia y Países Bajos.Fundación Española para la Ciencia y la Tecnología-Ministerio de Ciencia, Innovación y Universidades; Consejería de la Presidencia, Administración Pública e Interior de la Junta de Andalucía; Estrategia de Política de Investigación y Transferencia de la Universidad de Huelva; Cátedra de Innovación Social de Aguas de Huelva; Cátedra de la Provincia; Grupo de investigación TEP-192 de Control y Robótica; Centro de Investigación en Tecnología, Energía y Sostenibilidad (CITES

Oxidative stress and pro-inflammatory status in patients with non-alcoholic fatty liver disease
Background: Nonalcoholic fatty liver disease (NAFLD) is characterized by excessive fat
accumulation, especially triglycerides, in hepatocytes. If the pathology is not properly treated, it can
progress to nonalcoholic steatohepatitis (NASH) and continue to fibrosis, cirrhosis or hepatocarcinoma.
Objective: The aim of the current research was to identify the plasma biomarkers of liver damage,
oxidative stress and inflammation that facilitate the early diagnosis of the disease and control its
progression. Methods: Antioxidant and inflammatory biomarkers were measured in the plasma
of patients diagnosed with NAFLD (n = 100 adults; 40–60 years old) living in the Balearic Islands,
Spain. Patients were classified according to the intrahepatic fat content (IFC) measured by magnetic
resonance imaging (MRI). Results: Circulating glucose, glycosylated haemoglobin, triglycerides,
low-density lipoprotein-cholesterol, aspartate aminotransferase and alanine aminotransferase were
higher in patients with an IFC ≥ 2 of NAFLD in comparison to patients with an IFC of 0 and 1.
The plasma levels of catalase, irisin, interleukin-6, malondialdehyde, and cytokeratin 18 were higher
in stage ≥2 subjects, whereas the resolvin D1 levels were lower. No differences were observed
in xanthine oxidase, myeloperoxidase, protein carbonyl and fibroblast growth factor 21 depending on
liver status. Conclusion: The current available data show that the severity of NAFLD is associated
with an increase in oxidative stress and proinflammatory status. It may be also useful as diagnostic
purpose in clinical practice
