Selective Change Driven Imaging: A Biomimetic Visual Sensing Strategy
Selective Change Driven (SCD) Vision is a biologically inspired strategy for acquiring, transmitting and processing images that significantly speeds up image sensing. SCD vision is based on a new CMOS image sensor which delivers, ordered by the absolute magnitude of its change, the pixels that have changed after the last time they were read out. Moreover, the traditional full frame processing hardware and programming methodology has to be changed, as a part of this biomimetic approach, to a new processing paradigm based on pixel processing in a data flow manner, instead of full frame image processing
Isolated Fe(III)-O Sites Catalyze the Hydrogenation of Acetylene in Ethylene Flows under Front-End Industrial Conditions
[EN] The search for simple, earth-abundant, cheap, and nontoxic metal catalysts able to perform industrial hydrogenations is a topic of interest, transversal to many catalytic processes. Here, we show that isolated FeIII¿O sites on solids are able to dissociate and chemoselectively transfer H2 to acetylene in an industrial process. For that, a novel, robust, and highly crystalline metal¿organic framework (MOF), embedding FeIII¿OH2 single sites within its pores, was prepared in multigram scale and used as an efficient catalyst for the hydrogenation of 1% acetylene in ethylene streams under front-end conditions. Cutting-edge X-ray crystallography allowed the resolution of the crystal structure and snapshotted the single-atom nature of the catalytic FeIII¿O site. Translation of the active site concept to even more robust and inexpensive titania and zirconia supports enabled the industrially relevant hydrogenation of acetylene with similar activity to the Pd-catalyzed process.This work was supported by the MINECO (Spain) (Projects CTQ2016-75671-P, CTQ2014-56312-P, CTQ2014-55178-R, and Excellence Units "Severo Ochoa" and "Maria de Maeztu" SEV-2016-0683 and MDM-2015-0538) and the Ministero dell'Istruzione, dell'Universita e della Ricerca (Italy) (FFABR 2017).

Biomarkers predictive value for early diagnosis of stroke- associated pneumonia
Stroke-associated pneumonia; SAP; Diagnostic accuracy; BiomarkersNeumonía asociada al accidente cerebrovascular; NAA; Precisión diagnóstica; BiomarcadoresPneumònia associada a l'accident cerebrovascular; Precisió diagnòstica; BiomarcadorsTo confirm the diagnostic accuracy of candidate biomarkers in stroke‐associated pneumonia (SAP), we prospectively enrolled ischemic stroke patients with NIHSS ≥ 10 on admission from March‐2016 to August‐2017. Blood samples were collected at baseline, 24 and 48 h after stroke onset. Biomarkers (MR‐proADM, suPAR, SAA) were determined by immunoassays. Regarding biomarkers, MR‐proADM at 24 h (P = 0.04) and both suPAR and SAA at 48 h (P = 0.036 and P = 0.057) were associated with pneumonia. The combination of SAA > 25.15 mg/dL and suPAR> 3.14 ng/mL at 48 h had 80% sensitivity and 95.8% specificity when both biomarkers were above the cut‐off. The evaluated biomarkers represent promising tools to be evaluated in future large, prospective studies on SAP. An accurate SAP diagnosis by thorax CT might help to reduce variability in such studies.This project was partially funded by the ISCIII project PI14/00971.

Changes in severity, mortality, and virus genome among a Spanish cohort of patients hospitalized with SARS-CoV-2
Comparing pandemic waves could aid in understanding the evolution of COVID-19. The objective of the present study was to compare the characteristics and outcomes of patients hospitalized for COVID-19 in different pandemic waves in terms of severity and mortality. We performed an observational retrospective cohort study of 5,220 patients hospitalized with SARS-CoV-2 infection from February to September 2020 in Aragon, Spain. We compared ICU admissions and 30-day mortality, clinical characteristics, and risk factors of the first and second waves of COVID-19. The SARS-CoV-2 genome was also analyzed in 236 samples. Patients in the first wave (n¿=¿2,547) were older (median age 74 years [IQR 60–86] vs. 70 years [53–85]; p¿<¿0.001) and had worse clinical and analytical parameters related to severe COVID-19 than patients in the second wave (n¿=¿2,673). The probability of ICU admission at 30 days was 16% and 10% (p¿<¿0.001) and the cumulative 30-day mortality rates 38% and 32% in the first and second wave, respectively (p¿=¿0.007). Survival differences were observed among patients aged 60 to 80 years. We also found some variability among death risk factors and the viral genome between waves. Therefore, the two analyzed COVID-19 pandemic waves were different in terms of disease severity and mortality
Socio-cultural, historical, political and economic dimensions of health and medicine
Health is one of the most important areas of human development and, along with quality of life, occupies a prominent place in the academic world, being studied from various theoretical perspectives and from different scientific disciplines. These studies try to explain, from the micro to the macro, what it means and what elements are involved in the health of individuals in particular and of society in general. However, given the diversity of perspectives, there is no consensus on the definition of health. At the beginning, the study of health focused on biomedical research into disease. This approach has shown its limits in understanding health in its most complete dimension, as defined by the World Health Organization as early as 1946 : “ health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity ” ( preamble to the WHO Constitution, 1946 ). This “ positive ” orientation of health is later taken up as a universal human right ( Declaration of Human Rights, art. 25 ), being considered today not only a right, but also a value in itself, an aspiration and a social demand....Peer reviewe
