Estimaciones del pleno empleo de las regiones españolas: métodos de alisamiento, equilibrio a largo plazo y el enfoque de los salarios
La Cumbre Europea de Lisboa (2000) señaló, entre otras cuestiones, los
fuertes desequilibrios regionales existentes en Europa en materia de desempleo. Sin embargo, en la misma se decidió plantear los objetivos para el mercado de trabajo no en función del nivel de desempleo, sino en función del nivel de empleo: se pretende que el 70% de la población adulta (15-64 años) tenga empleo en el año 2010. Esta tasa de empleo implica aproximadamente una tasa de desempleo del 5%. Esta tasa parece ser la
tasa consensuada de pleno empleo pero es necesaria una aproximación econométrica para estimar esta variable inobservable.
La economía española no es precisamente ajena a los desequilibrios anteriores. Por ello, en este trabajo estimamos el pleno empleo de cada una de las regiones españolas. Para atender a dicha finalidad utilizamos distintas metodologías, lo que nos permite realizar comparaciones: a) Métodos de alisamiento (mínimo desempleo histórico, medias
móviles y filtro de Hodrick-Prescott); b) Equilibrio a largo plazo (solución particular de un AR(1) para la tasa de desempleo); y c) El enfoque de los salarios (estimación de "time-varying" NAWRUs utilizando el método de Elmeskov)
Curvas de Phillips y NAWRUs regionales: Evidencia empírica para la economía española
En este trabajo proporcionamos estimaciones de las NAWRUs (Tasa de Desempleo no Aceleradora de los Salarios) regionales de la economía española para el periodo 1989-2000. Hemos utilizado el método de Elmeskov, ampliamente implementado en la última década -por ejemplo en el marco del FMI y la OCDE- con el objetivo de obtener una "time-varying" NAWRU. Estas estimaciones nos permiten introducir el desempleo cíclico como argumento de las curvas de Phillips para las distintas Comunidades Autónomas. Los resultados obtenidos no reflejan la esperada relación negativa entre inflación salarial y desempleo.NAWRU, hysteresis, Phillips curve, regional labour markets.
An example of adaptation: experience of virtual clinical skills circuits of internal medicine students at the Faculty of Medicine, University of Granada (Spain) during the COVID-19 pandemic
Background: The state of alarm declared in Spain in response to the Coronavirus pandemic
(COVID-19) has had far-reaching consequences in all areas of life. At the University of
Granada’s (UGR) Faculty of Medicine, online teaching was implemented immediately without
any preexisting plan. Second-year undergraduates in medicine, particularly those enrolled in
the subject ‘Bases of Internal Medicine,’ would normally undergo clinical skills circuits in faceto-
face group settings.
Objective: To facilitate undergraduates’ acquisition of specific transversal skills by means of
an integrated online working system.
Design: Before the pandemic, teaching/learning methods consisted of 1) face-to-face group
work; 2) teletutoring; 3) written work uploaded to the PRADO online platform for marking by
the teletutor; and 4) presentation of written work to the group. As a result of the lockdown,
presentations in class were suspended and replaced by online presentations. The means
adopted by students in online presentations were freely chosen using various communication
techniques: linear projection systems (6); acting/simulation (4); dramatization (1); and roleplaying
(1).
Results: The number of online clinical skills circuits developed was 12, one for each of the
clinical skills circuits established for imparting this subject. A total of 12 presentations were
made by the 10 groups, each lasting 15 minutes followed by a 5-minute discussion to settle
any questions raised. The presentations were marked jointly by the teaching staff, coordinator,
and students.
Conclusions: The transference of classroom learning to the online environment proved an
essential resource for teaching/learning clinical/practical skills during the lockdown, which
have never before been imparted at distance
Wearable System for Biosignal Acquisition and Monitoring Based on Reconfigurable Technologies
Wearable monitoring devices are now a usual commodity in the market, especially for the
monitoring of sports and physical activity. However, specialized wearable devices remain an open
field for high-risk professionals, such as military personnel, fire and rescue, law enforcement, etc.
In this work, a prototype wearable instrument, based on reconfigurable technologies and capable
of monitoring electrocardiogram, oxygen saturation, and motion, is presented. This reconfigurable
device allows a wide range of applications in conjunction with mobile devices. As a proof-of-concept,
the reconfigurable instrument was been integrated into ad hoc glasses, in order to illustrate the
non-invasive monitoring of the user. The performance of the presented prototype was validated
against a commercial pulse oximeter, while several alternatives for QRS-complex detection were
tested. For this type of scenario, clustering-based classification was found to be a very robust option.This work was funded by Banco Santander and Centro Mixto UGR-MADOC through project SIMMA

Design of a specific physical training program for first-time participants in basic life support
Objetivo: diseñar un programa de entrenamiento físico específico para profesionales del soporte vital básico que
permita superar la fatiga que éstos padecen durante el desarrollo de la reanimación cardiopulmonar con el fin de
proporcionar un masaje cardiaco de mayor calidad durante periodos de tiempo más largos.
Método: el entrenamiento interválico de alta intensidad mejora la capacidad física y la salud al tiempo que reduce
los niveles de grasa y aumenta el metabolismo basal mediante la alternancia entre ejercicios de alta y baja intensidad
mejorando la capacidad anaeróbica y la disponibilidad aeróbica, lo que hace de este tipo de entrenamiento
una herramienta idónea para trabajar con los profesionales de la reanimación cardiopulmonar.
Resultado: programa de entrenamiento por estaciones que combinando actividades dinámicas de alta intensidad,
ejercicios de fuerza en los que se implica directamente la musculatura interviniente en la reanimación cardiopulmonar
y ejercicios en los que se utiliza el propio simulador de reanimación cardiopulmonar, permite adecuarnos
al entrenamiento de alta intensidad aumentando la fuerza y la funcionalidad.
Conclusiones: la relación existente entre el ejercicio físico y la calidad de las técnicas de reanimación cardiopulmonar
impone la necesidad de desarrollar estudios específicos de las rutas metabólicas y los grupos musculares
específicos que participan en estas técnicas con el objetivo de generar un programa de entrenamiento físico específico
para los profesionales que participan en esta actividad para mejorar la calidad de dichas técnicas e influir
de forma positiva en la supervivencia de los pacientes afectados por un episodio de parada cardiorrespiratoria.Objective: to design a specific physical training program for basic life support professionals to overcome the fatigue
they suffer during the development of cardiopulmonary resuscitation in order to provide a higher
quality cardiac massage for longer periods.
Method: high intensity interval training improves physical fitness and health, reduce fat levels and increase
basal metabolism by high and low intensity exercises alternation, improving anaerobic capacity
and aerobic availability, which make this type of training an ideal tool for working with cardiopulmonary
resuscitation professionals.
Result: a circuit training program that allow us for adapting to a high intensity interval training combining high
intensity activities, strength exercises that work the participant musculature in cardiopulmonary resuscitation
and exercises in which the cardiopulmonary resuscitation simulator is used.
Conclusions: the connection between physical exercise and cardiopulmonary resuscitation techniques quality
impose the need to develop specific studies of metabolic pathways and participant muscle groups in cardiopulmonary
resuscitation to generate a specific physical training program for professionals who participate in this
activity in order to improve these techniques quality and cardiorespiratory arrest survival
Analysis of the development of the forgetfulness curve within a program of training in Basic Life Support for students of the Degree of Medicine from de University of granada. Pilot study.
Objetivo: El objetivo del estudio es analizar la curva del olvido en el aprendizaje del Soporte Vital Básico en estudiantes
de medicina de la Universidad de Granada.
Material y métodos: Se trata de un estudio observacional, descriptivo transversal, que establece como población
diana a los estudiantes de Grado de Medicina de la Universidad de Granada que cursan cuarto y quinto curso.
Periodo de estudio comprendido entre octubre de 2015 y enero de 2017.Se emplearon los datos obtenidos en una
evaluación inicial que se realizó en la Facultad de Medicina, y los de una reevaluación que se les realizó a una muestra
de cada uno de los cursos. Se incluyeron en el estudio de forma voluntaria todos los alumnos matriculados en
la asignatura bases de la medicina interna II para cada uno de los cursos académicos. El análisis se realizó utilizando
medidas de tendencia central, tablas de frecuencias y posteriormente se realizó un análisis estadístico mediante la
Prueba T de Student.
Resultados: Los alumnos de cuarto consiguieron una media en la primera evaluación de 13,91 sobre 15 puntos,
mientras que en la segunda la media fue de 13,81. Por otro lado, los alumnos de quinto consiguieron una media de
13,80 en la primera evaluación y una de 13,18 en la reevaluación. Estos datos nos hablan de que, a pesar de que
los cursos resultaron muy satisfactorios en ambos cursos, encontramos un mayor impacto de la curva del olvido en
alumnos que llevan más tiempo sin realizar un reciclaje en Soporte Vital Básico.
Conclusiones: A pesar de existir una disminución de los conocimientos y habilidades relacionados con la práctica
del soporte vital al año de recibir la formación específica en ambos grupos, no existen diferencias estadísticamente
significativas para los sujetos de nuestro grupo que obliguen a establecer programas de reciclaje entre seis y nueve
meses como establecen las recomendaciones actuales. A la luz de nuestro estudio, recomendamos el desarrollo
de programas específicos de reciclaje en períodos de tiempo superiores a los doce meses después de recibir la
formación inicial.Aim: The aim of this study was to analyze the oblivion curve after the learning of Basic Life Support (BLS) in medicine
students from the University of Granada.
Method: This was an observational, transversal descriptive study, which established as target population students
from the Faculty of Medicine (University of Granada) who attended fourth and fifth year. The Study period comprised between October 2015 and January 2017. The data which was used was obtained in an initial evaluation that was
done at the Faculty of Medicine and in a re-evaluation which was applied to a selected sample of students from each
year. All the students included voluntarily in the study were enrolled in the subject Internal Medicine II. The analysis
was carried out using measures of central tendency, frequency tables and after that, a statistical analysis using the
Student´s T-test.
Results: Fourth year students obtained an average in the first evaluation of 13,91 over 15 points, while in the second
evaluation it was 13,81. Meanwhile, fifth year students achieved an average of 13,80 in the first evaluation and of
13,18 in the re-evaluation. This data speak of very satisfactory results for students in both years, although the impact
of the oblivion curve is higher in students who have spent more time without taking a recycling course of BLS.
Conclusions:.Even though there is a decrease of knowledge and abilities related to the practice of basic life support
a year after receiving the specific training in both groups, there are not differences statistically significant for the
subjects of our group that would make us establish recycling programs after six or nine months, as advice the actual
recommendations. 2.Based on the results we obtained, we would recommend the development of specific recycling
programs in periods of time bigger than twelve months after receiving the initial training

Antimicrobial defined daily dose (DDD), a standardized metric to assess antimicrobial consumption in adult population, has limitations hampering its use in neonatal patients. This study proposes an alternative DDD design applicable for neonates.
Methods
Neonates (<1 month-old) from 6 Spanish hospitals during a 12-months period were included. Weight and weeks gestational age of each neonate were the variables collected. DDD (g) for each antimicrobial was calculated by multiplying the obtained weight times the recommended dose (mg/kg) of the antimicrobial for the most common infectious indication selected by the Delphi method.
Results
A total of 4820 neonates were included. Mean age was 36.72 weeks of gestational age and Mean weight was 2.687 kg. Standardized DDD (intravenous; oral route) for representative antimicrobials were: Amoxicillin (0.08; 0.08), amoxicillin-clavulanic acid (0.27; 0.08), ampicillin (0.27; x), cloxacillin (0.13; 0.13), penicillin G sodium (0.12), cefazolin (0.13), cefuroxime (0.27; x), cefotaxime (0.27), ceftazidime (0.27), ceftriaxone (0.13), cefepime (0.27) piperacillin-tazobactam (0.54), aztreonam (0.24), azithromycin (0.03; 0.03), clindamycin (0.04; 0.04), amikacin (0.04), gentamicin (0.01), metronidazole (0.04; 0.08), ciprofloxacin (0.04; 0.05), levofloxacin (x;x), fluconazole (0.02; 0.02), itraconazole (0.01; 0.01), fosfomycin (0.27). Restricted antimicrobials: meropenem (0.11), teicoplanin (0.02), vancomycin (0.08; 0.11), linezolid (0.08; 0.08), daptomycin (x), amphotericin B liposomal (0.01).
Conclusions
A useful method for antimicrobial DDD measurement in neonatology has been designed to monitor antimicrobial consumption in hospital settings. It should be validated in further studies and thereby included in the design for neonatal antimicrobial stewardship programs in the future.Antecedentes

Feasibility and safety of low-flow extracorporeal carbon dioxide removal to facilitate ultra-protective ventilation in patients with moderate acute respiratory distress sindrome
BACKGROUND: Mechanical ventilation with a tidal volume (V(T)) of 6 mL/kg/predicted body weight (PBW), to maintain plateau pressure (P(plat)) lower than 30 cmH(2)O, does not completely avoid the risk of ventilator induced lung injury (VILI). The aim of this study was to evaluate safety and feasibility of a ventilation strategy consisting of very low V(T) combined with extracorporeal carbon dioxide removal (ECCO(2)R). METHODS: In fifteen patients with moderate ARDS, V(T) was reduced from baseline to 4 mL/kg PBW while PEEP was increased to target a plateau pressure – (P(plat)) between 23 and 25 cmH(2)O. Low-flow ECCO(2)R was initiated when respiratory acidosis developed (pH < 7.25, PaCO(2) > 60 mmHg). Ventilation parameters (V(T), respiratory rate, PEEP), respiratory compliance (C(RS)), driving pressure (DeltaP = V(T)/C(RS)), arterial blood gases, and ECCO(2)R system operational characteristics were collected during the period of ultra-protective ventilation. Patients were weaned from ECCO(2)R when PaO(2)/FiO(2) was higher than 200 and could tolerate conventional ventilation settings. Complications, mortality at day 28, need for prone positioning and extracorporeal membrane oxygenation, and data on weaning from both MV and ECCO(2)R were also collected. RESULTS: During the 2 h run in phase, V(T) reduction from baseline (6.2 mL/kg PBW) to approximately 4 mL/kg PBW caused respiratory acidosis (pH < 7.25) in all fifteen patients. At steady state, ECCO(2)R with an average blood flow of 435 mL/min and sweep gas flow of 10 L/min was effective at correcting pH and PaCO(2) to within 10 % of baseline values. PEEP values tended to increase at V(T) of 4 mL/kg from 12.2 to 14.5 cmH(2)O, but this change was not statistically significant. Driving pressure was significantly reduced during the first two days compared to baseline (from 13.9 to 11.6 cmH(2)O; p < 0.05) and there were no significant differences in the values of respiratory system compliance. Rescue therapies for life threatening hypoxemia such as prone position and ECMO were necessary in four and two patients, respectively. Only two study-related adverse events were observed (intravascular hemolysis and femoral catheter kinking). CONCLUSIONS: The low-flow ECCO(2)R system safely facilitates a low volume, low pressure ultra-protective mechanical ventilation strategy in patients with moderate ARDS

Polarimetric imaging for the detection of synthetic models of SARS-CoV-2: A proof of concept
Objective: To conduct a proof-of-concept study of the detection of two synthetic models of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using polarimetric imaging. Approach: Two SARS-CoV-2 models were prepared as engineered lentiviruses pseudotyped with the G protein of the vesicular stomatitis virus, and with the characteristic Spike protein of SARS-CoV-2. Samples were prepared in two biofluids (saline solution and artificial saliva), in four concentrations, and deposited as 5-µL droplets on a supporting plate. The angles of maximal degree of linear polarization (DLP) of light diffusely scattered from dry residues were determined using Mueller polarimetry from87 samples at 405 nm and 514 nm. A polarimetric camera was used for imaging several samples under 380–420 nm illumination at angles similar to those of maximal DLP. Per-pixel image analysis included quantification and combination of polarization feature descriptors in 475 samples. Main results: The angles (from sample surface) of maximal DLP were 3° for 405 nm and 6° for 514 nm. Similar viral particles that differed only in the characteristic spike protein of the SARS-CoV-2, their corresponding negative controls, fluids, and the sample holder were discerned at 10-degree and 15-degree configurations. Significance: Polarimetric imaging in the visible spectrum may help improve fast, non-contact detection and identification of viral particles, and/or other microbes such as tuberculosis, in multiple dry fluid samples simultaneously, particularly when combined with other imaging modalities. Further analysis including realistic concentrations of real SARS-CoV-2 viral particles in relevant human fluids is required. Polarimetric imaging under visible light may contribute to a fast, cost-effective screening of SARS-CoV-2 and other pathogens when combined with other imaging modalities.12 página
