Nueva forma de entender las pruebas de condición física en relación con la salud

El objetivo de este trabajo es mostrar una nueva forma de entender la evaluación de la “condición física en relación con la salud”, para evitar la inactividad y el sedentarismo. Los antecedentes se encuentran en las baterías de test utilizadas desde 1976 hasta la actualidad. Se utiliza el concepto de salud de la OMS. Se analizan pruebas con criterios de funcionalidad, economía, validez, fiabilidad y especificidad. Se eligen las siguientes pruebas y se calculan los umbrales: UKK Walk test (P75), 6” en sprint test 20 m (P75), 19 repeticiones en Chair Stand Test(P25), 11 repeticiones Arm Curl Test (P25), -10,5 cm Back Scratch Test (P25), -17,5 cm en Chair Sit and Reach Test. Se propugna la elaboración de una batería de test universal e inclusiva y elaborar percentiles mundiales ayudados por el big dataThe aim of this research was to propose a new way of understanding health-related physical fitness assessment in order to prevent inactivity and sedentarism. The background lies in the test batteries used from 1976 to the present. WHO's health concept was used. Tests were analysed based on functionality, economy, validity, reliability and specificity criteria. The following tests were chosen and the thresholds were calculated: 1,425s in the UKK walk test (P75), 6s in the 20-m sprint test (P75), 19 repetitions in the chair stand test (P25), 11 repetitions in the arm curl test (P25), -10.5cm in the back scratch test (P25), -17.5cm in the chair sit-and-reach test (P25). It was proposed that a universal and inclusive test battery be developed and the percentiles for the world population are determined with the help of big dat

Health aspects of physical education in the Community of Madrid (Spain)

Casi el 50% del alumnado tiene alguna enfermedad crónica. El desarrollo corporal es normal, la adaptación cardiovascular no es mala pero mejorable. La actividad física resulta insuficiente, la valoración de la condición física es inadecuada. Las instalaciones deportivas escolares en los centros públicos son claramente deficientes desde el punto de vista de la salud. Por último, en ninguno de los centros, el profesorado había recogido estos datos antes de la elaboración de esta investigación, salvo adaptaciones curriculares concretas pedidas por el alumnado. Es necesario buscar nuevas metodologías que estén ajustadas a criterios de salud y coordinadas con los servicios de saludThe results of this study, note that almost 50 % of students claim to have a chronic disease, vision problems are the most predominant. On the other hand, we can see that the physical development is suited to the average population; cardiovascular adaptation of students is not bad but should be better. In addition, school physical activity is insufficient, the assessment of the physical condition is inadequate and in public schools, school sports facilities are clearly deficient from the point of view of health. Finally, it is noted that none of the schools, the teachers had collected this data before making this research, except specific curricular adaptations requested by the student. It is necessary that teachers look for new work methods that comply with health criteria and that are coordinated with health service

Severe manifestations of SARS-CoV-2 in children and adolescents: from COVID-19 pneumonia to multisystem inflammatory syndrome: a multicentre study in pediatric intensive care units in Spain

Background Multisystem inflammatory syndrome temporally associated with COVID-19 (MIS-C) has been described as a novel and often severe presentation of SARS-CoV-2 infection in children. We aimed to describe the characteristics of children admitted to Pediatric Intensive Care Units (PICUs) presenting with MIS-C in comparison with those admitted with SARS-CoV-2 infection with other features such as COVID-19 pneumonia. Methods A multicentric prospective national registry including 47 PICUs was carried out. Data from children admitted with confirmed SARS-CoV-2 infection or fulfilling MIS-C criteria (with or without SARS-CoV-2 PCR confirmation) were collected. Clinical, laboratory and therapeutic features between MIS-C and non-MIS-C patients were compared. Results Seventy-four children were recruited. Sixty-one percent met MIS-C definition. MIS-C patients were older than non-MIS-C patients (p = 0.002): 9.4 years (IQR 5.5–11.8) vs 3.4 years (IQR 0.4–9.4). A higher proportion of them had no previous medical history of interest (88.2% vs 51.7%, p = 0.005). Non-MIS-C patients presented more frequently with respiratory distress (60.7% vs 13.3%, p < 0.001). MIS-C patients showed higher prevalence of fever (95.6% vs 64.3%, p < 0.001), diarrhea (66.7% vs 11.5%, p < 0.001), vomits (71.1% vs 23.1%, p = 0.001), fatigue (65.9% vs 36%, p = 0.016), shock (84.4% vs 13.8%, p < 0.001) and cardiac dysfunction (53.3% vs 10.3%, p = 0.001). MIS-C group had a lower lymphocyte count (p < 0.001) and LDH (p = 0.001) but higher neutrophil count (p = 0.045), neutrophil/lymphocyte ratio (p < 0.001), C-reactive protein (p < 0.001) and procalcitonin (p < 0.001). Patients in the MIS-C group were less likely to receive invasive ventilation (13.3% vs 41.4%, p = 0.005) but were more often treated with vasoactive drugs (66.7% vs 24.1%, p < 0.001), corticosteroids (80% vs 44.8%, p = 0.003) and immunoglobulins (51.1% vs 6.9%, p < 0.001). Most patients were discharged from PICU by the end of data collection with a median length of stay of 5 days (IQR 2.5–8 days) in the MIS-C group. Three patients died, none of them belonged to the MIS-C group. Conclusions MIS-C seems to be the most frequent presentation among critically ill children with SARS-CoV-2 infection. MIS-C patients are older and usually healthy. They show a higher prevalence of gastrointestinal symptoms and shock and are more likely to receive vasoactive drugs and immunomodulators and less likely to need mechanical ventilation than non-MIS-C patients

Design, characterization and installation of the NEXT-100 cathode and electroluminescence regions

NEXT-100 is currently being constructed at the Laboratorio Subterr\'aneo de Canfranc in the Spanish Pyrenees and will search for neutrinoless double beta decay using a high-pressure gaseous time projection chamber (TPC) with 100 kg of xenon. Charge amplification is carried out via electroluminescence (EL) which is the process of accelerating electrons in a high electric field region causing secondary scintillation of the medium proportional to the initial charge. The NEXT-100 EL and cathode regions are made from tensioned hexagonal meshes of 1 m diameter. This paper describes the design, characterization, and installation of these parts for NEXT-100. Simulations of the electric field are performed to model the drift and amplification of ionization electrons produced in the detector under various EL region alignments and rotations. Measurements of the electrostatic breakdown voltage in air characterize performance under high voltage conditions and identify breakdown points. The electrostatic deflection of the mesh is quantified and fit to a first-principles mechanical model. Measurements were performed with both a standalone test EL region and with the NEXT-100 EL region before its installation in the detector. Finally, we describe the parts as installed in NEXT-100, following their deployment in Summer 2023.Comment: 35 pages, 25 Figures, update includes accepted version in JINS

A Compact Dication Source for Ba2+^{2+} Tagging and Heavy Metal Ion Sensor Development

We present a tunable metal ion beam that delivers controllable ion currents in the picoamp range for testing of dry-phase ion sensors. Ion beams are formed by sequential atomic evaporation and single or multiple electron impact ionization, followed by acceleration into a sensing region. Controllability of the ionic charge state is achieved through tuning of electrode potentials that influence the retention time in the ionization region. Barium, lead, and cobalt samples have been used to test the system, with ion currents identified and quantified using a quadrupole mass analyzer. Realization of a clean $\mathrm{Ba^{2+}}$ ion beam within a bench-top system represents an important technical advance toward the development and characterization of barium tagging systems for neutrinoless double beta decay searches in xenon gas. This system also provides a testbed for investigation of novel ion sensing methodologies for environmental assay applications, with dication beams of Pb$^{2+}$ and Cd$^{2+}$ also demonstrated for this purpose
