Quality of Work Life and Mental Health in Primary Care Physicians
AbstractThe aim of this study was to find the relationship between the perception of Quality of Work Life (QWL) and the mental health of primary care physicians of a public health institution in Guadalajara, Mexico. The study was analytical and was carried out with a universe of 818 doctors from 92 health units and the probability sample of 154 people. In all of them, CVT-GOHISALO and Goldberg GHQ-28 questionnaires were applied in order to measure their perception of QWL and the risk of mental illness respectively. Both instruments were selected because of their high reliability. We measured the satisfaction of the people interviewed for each one of the seven dimensions of CVT-GOHISALO and related to the points assigned to GHQ-28 case or not to consider the case of mental illness. The percentages of dissatisfaction with the QWL were greater than 12% in all dimensions of the instrument, being the highest value of 20.5% dissatisfaction for the job satisfaction dimension. In the classification of the case or not according to the GHQ-28, 22% were considered cases and 78% non-cases. We sought correspondence of satisfaction with the QWL by dimensions and non-case of Goldberg's, as well as dissatisfaction with the QWL and Goldberg's case, finding a clear link between being satisfied and having mental health. All dimensions have a correspondence that goes from 79.7% to 82.3% between satisfaction and non-case, being in all the statistical significance value less than 0.05 For primary care physicians in the studied institution, there is a clear relationship between being satisfied with the QWL and present less risk of mental illness. It is alarming that the medical staff presents high rates of dissatisfaction with the QWL and risk of mental illness. It is necessary to provide preventive programs among health care workers in order to improve their QWL and mental health
Valoración a medio-largo plazo de los cotilos de Mittelmeier
El objetivo del presente trabajo es valorar clínica y radiológicamente la evolución
de 125 cotilos de Mittelmeier implantados en nuestro servicio, con un seguimiento medio de
8 años (5,5-14). En toda la serie se ha utilizado un mismo tipo de cotilos, aunque se han utilizado
2 vástagos, los de segunda y los de tercera generación. El comportamiento ha sido satisfactorio
en el 91% de los de tercera generación y el 57% en los de segunda. Se comprobó una inclinación
y recubrimientos progresivos y una emigración horizontal y vertical significativas de los cotilos.
No se encontró relación entre los resultados clínicos y las alteraciones posicionales. La
movilización del cotilo aparece en nuestra serie mucho más frecuentemente que en la mayor parte
de la literatura. Las emigraciones horizontal y vertical pueden ser debidas a los diferentes coeficientes
de elasticidad de la cerámica y el hueso sin implicar necesariamente malos resultados.
Como conclusión, el comportamiento de los cotilos de Mittelmeier ha sido en general satisfactorio
a pesar de las emigraciones, que han tenido escasa repercusión clínica.This study was aimed at evaluating clinically and radiologically the results of 125
Mittelmeier cups implanted in our institution, with a mean follow-up of 8 years (5.5-14). The same
type of cup was used in the whole series, combined with two types of femoral stem from the
2
nd
and 3rd
generations. The results were satisfactory in 91 % of cases treated with the 3rd
generation
and 57% in those cases treated with the 2nd
generation of implants. Progressive inclination
and coverage were detected with both horizontal and vertical migration of the cups. No relationship
was found between clinical results and the displacements observed. In this series, migrations
of the cup were more frequent than those published by other authors. Horizontal and vertical
migratrion may be due to the difference between the coefficients of elasticity of ceramic and
bone. Cup migration did not imply poor results. In conclusion, the overall results obtained with
the Mittelmeier cups were satisfactory, in spite of migration. The clinical repercussion of cup migrations
was minimal
Más allá del humo : la ecología política de los incendios forestales a partir del caso de Horta de Sant Joan (Tarragona, Cataluña)
Analizamos el dramático incendio de Horta de Sant Joan de 2009 en Cataluña, bajo el marco de la ecología política. La historia ambiental local, los cambios de usos del paisaje forestal anterior al incendio y el choque entre los diferentes discursos sociales alrededor de éste revelan diferentes formas sociopolíticas de construir la relación entre la naturaleza y la sociedad. Cada actor social explica y evalúa la gestión del territorio y del incendio mediante escalas de tiempo e intereses diferentes. Estos distintos discursos se pueden clasificar según el grado en que favorecen la inclusión o la exclusión del fuego en el sistema socioecológico. Nuestro análisis muestra los diferentes «paisajes deseados» propuestos por los actores sociales, cuya contextualización y análisis permiten realizar una reflexión más profunda sobre los valores dominantes y dominados en relación con los bosques y los incendios. Concluimos que es necesaria una adecuada politización del debate en torno a las causas de los incendios forestales y las formas en las que la sociedad catalana responde a ellos. Analitzem el dramàtic incendi d'Horta de Sant Joan de 2009 a Catalunya en el marc de l'ecologia política. La història ambiental local, els canvis d'usos del paisatge forestal anterior a l'incendi i el xoc entre els diferents discursos socials al voltant d'aquest ens parlen de diferents formes sociopolítiques de construir la relació entre natura i societat. Cada actor social explica i avalua la gestió del territori i de l'incendi d'acord amb escales temporals i interessos diferents. Els diversos discursos es poden classificar segons el grau d'inclusió o exclusió del foc en el sistema socioecològic. La nostra anàlisi mostra els «paisatges desitjats » de cada actor social, la contextualització i l'anàlisi dels quals permeten realitzar una reflexió més profunda sobre els valors dominants i dominats en relació amb els boscos i els incendis. Concloem que és necessària una politització adequada del debat sobre les causes dels incendis forestals i les respostes que la societat catalana hi dóna. Nous analysons le dramatique incendie de Horta de Sant Joan en 2009 en Catalogne, dans le cadre de l'écologie politique. L'histoire locale de l'environnement, les changements dans le paysage forestier utilisé avant l'incendie et l'affrontement entre différents discours sociaux autour du feu, réalisent différentes façons socio-politiques de construire la relation société-nature. Chaque acteur social, explique et évalue la gestion des terres et du feu selon différentes échelles de temps et intérêts. Ces différents discours peuvent être classés en fonction de la mesure qui favorisent l'inclusion ou l'exclusion du feu dans le système socio-écologique. Notre analyse met en lumière les différents «paysages souhaités» proposé par les acteurs sociaux, dont la contextualisation et l'analyse de permettre une réflexion plus profonde sur les valeurs dominantes et dominées par rapport aux forêts et aux incendies. Nous concluons qu'il doit y avoir politisation appropriée autour les causes et les réponses des feux de forêt en Catalogne. This paper analyses the tragic 2009 wildfire of Horta de Sant Joan in Catalonia. The local environmental history, the changes in land use of the pre-fire forest landscape, and the clash between different social discourses after the wildfire reveal different sociopolitical forms of constructing the relationship between nature and society. Each social actor explains wildfire and forest management according to different time scales and interests. These discourses can be classified by the degree of inclusion or exclusion of fire in the social-ecological system. The contextualisation and analysis of the «desired landscapes» proposed by the social actors allows for a deeper reflection on contested understandings and values in relation to forests and wildfires. We conclude by arguing in favour of a proper re-politicisation of the debate around the causes of and the responses to wildfires
The response of Iberian rivers to the North Atlantic Oscillation
In this study we analyzed the influence of the North Atlantic Oscillation (NAO) on the streamflow in 187 sub-basins of the Iberian Peninsula. Monthly and one-month lagged correlations were conducted to assess the spatio-temporal extent of the NAO influence on Iberian river discharges. Analysis of the persistence of the winter NAO throughout the year was also undertaken, together with analysis of streamflow anomalies during positive and negative NAO phases. Moving-window correlation analyses were conducted to assess potential changes in the temporal evolution of the NAO influence on Iberian streamflows. The results show that the NAO has a large impact on surface water resources throughout the Iberian Peninsula during winter, and in the Atlantic watershed during autumn. We showed that water resources management and snowmelt are causing the persistent dependence of streamflows on the previous winter NAO. We found that strongly positive streamflow anomalies occurred during winter, especially in the Atlantic watershed, and provide evidence of non-stationarity and spatial variability in the NAO influence on Iberian water resources
Inverse Low Gain Avalanche Detectors (iLGADs) for precise tracking and timing applications
Low Gain Avalanche Detector (LGAD) is the baseline sensing technology of the
recently proposed Minimum Ionizing Particle (MIP) end-cap timing detectors
(MTD) at the Atlas and CMS experiments. The current MTD sensor is designed as a
multi-pad matrix detector delivering a poor position resolution, due to the
relatively large pad area, around 1 ; and a good timing resolution,
around 20-30 ps. Besides, in his current technological incarnation, the timing
resolution of the MTD LGAD sensors is severely degraded once the MIP particle
hits the inter-pad region since the signal amplification is missing for this
region. This limitation is named as the LGAD fill-factor problem. To overcome
the fill factor problem and the poor position resolution of the MTD LGAD
sensors, a p-in-p LGAD (iLGAD) was introduced. Contrary to the conventional
LGAD, the iLGAD has a non-segmented deep p-well (the multiplication layer).
Therefore, iLGADs should ideally present a constant gain value over all the
sensitive region of the device without gain drops between the signal collecting
electrodes; in other words, iLGADs should have a 100 fill-factor by
design. In this paper, tracking and timing performance of the first iLGAD
prototypes is presented.Comment: Conference Proceedings of VCI2019, 15th Vienna Conference of

La educación en Salud Ocupacional
N/AComo se podrá apreciar, la importancia de la medicina ocupacional, data desde el siglo XVIII, cuando Ramazzini1 ponía énfasis en que a los pacientes se les debería de preguntar acerca de su ocupación, pues ya desde entonces se reconocía que la actividad laboral podría estar relacionada con la enfermedad de los pacientes. Actualmente la Salud Ocupacional no tiene un abordaje exclusivo en el campo de la medicina, sino que se ha convertido en una disciplina multidisciplinaria, donde pueden participar médicos, terapeutas, ingenieros, abogados, psicólogos, trabajadores sociales y muchos otros profesionales cuyas actividades se relacionan con la salud de los trabajadores, sobre todo en el ámbito de la prevención y de la intervención y no solamente en diagnosticar y curar las enfermedades relacionadas con la actividad laboral
Preparedness needs research: How fundamental science and international collaboration accelerated the response to COVID-19
The first cluster of patients suffering from coronavirus disease 2019 (COVID-19) was identified on December 21, 2019, and as of July 29, 2020, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections have been linked with 664,333 deaths and number at least 16,932,996 worldwide. Unprecedented in global societal impact, the COVID-19 pandemic has tested local, national, and international preparedness for viral outbreaks to the limits. Just as it will be vital to identify missed opportunities and improve contingency planning for future outbreaks, we must also highlight key successes and build on them. Concomitant to the emergence of a novel viral disease, there is a ‘research and development gap’ that poses a threat to the overall pace and quality of outbreak response during its most crucial early phase. Here, we outline key components of an adequate research response to novel viral outbreaks using the example of SARS-CoV-2. We highlight the exceptional recent progress made in fundamental science, resulting in the fastest scientific response to a major infectious disease outbreak or pandemic. We underline the vital role of the international research community, from the implementation of diagnostics and contact tracing procedures to the collective search for vaccines and antiviral therapies, sustained by unique information sharing efforts
Study of Microscopic Residual Stresses in an Extruded Aluminium Alloy Sample after Thermal Treatment
Abstract: A method is proposed to calculate the microscopic residual stresses in extruded cylindrical samples of non-ageing aluminium alloy 5083 (Al–Mg), arising from quenching in fresh water from 530°C. We start from the premise that the alloy is single-phase and non-isotropic on a microscopic scale; it consists of many grains that exhibit different mechanical response depending on their crystallographic orientation and neighboring grains. Microscopic residual stresses depend on the applied heat treatment, microstructure and mechanical strength of the individual grains. The stresses were calculated from neutron diffraction data. Genetic programming algorithms were used to calculate microscopic residual stresses, considering that each diffraction peak describes the stress distribution of a group of grains having a certain orientation, size and environment. The algorithm assigns a stress value to each grain according to the distribution of the diffraction peaks and the microstructural parameters of these grains.This work was supported by the Madrid Regional Government-FEDER grant Y2018/NMT-4668 (Micro-Stress-MAP-CM) and the project MAT2017-83825-C4-1-R. We would also like to express our gratitude to FLNR-JINP for the beam time allocated on the FSD instrument, and to the HeuristicLab Software developers
