Dorsal and median raphe neuronal firing dynamics characterized by nonlinear measures.

The dorsal (DRN) and median (MRN) raphe are important nuclei involved in similar functions, including mood and sleep, but playing distinct roles. These nuclei have a different composition of neuronal types and set of neuronal connections, which among other factors, determine their neuronal dynamics. Most works characterize the neuronal dynamics using classic measures, such as using the average spiking frequency (FR), the coefficient of variation (CV), and action potential duration (APD). In the current study, to refine the characterization of neuronal firing profiles, we examined the neurons within the raphe nuclei. Through the utilization of nonlinear measures, our objective was to discern the redundancy and complementarity of these measures, particularly in comparison with classic methods. To do this, we analyzed the neuronal basal firing profile in both nuclei of urethane-anesthetized rats using the Shannon entropy (Bins Entropy) of the inter-spike intervals, permutation entropy of ordinal patterns (OP Entropy), and Permutation Lempel-Ziv Complexity (PLZC). Firstly, we found that classic (i.e., FR, CV, and APD) and nonlinear measures fail to distinguish between the dynamics of DRN and MRN neurons, except for the OP Entropy. We also found strong relationships between measures, including the CV with FR, CV with Bins entropy, and FR with PLZC, which imply redundant information. However, APD and OP Entropy have either a weak or no relationship with the rest of the measures tested, suggesting that they provide complementary information to the characterization of the neuronal firing profiles. Secondly, we studied how these measures are affected by the oscillatory properties of the firing patterns, including rhythmicity, bursting patterns, and clock-like behavior. We found that all measures are sensitive to rhythmicity, except for the OP Entropy. Overall, our work highlights OP Entropy as a powerful and useful quantity for the characterization of neuronal discharge patterns.

Avanzando en la sistematización del benchmarking en servicios de salud pública / Improving the systematization of benchmarking in public health services

La mejora continua de la gestión debería ser una aspiración para todas las organizaciones del sector público. Los elementos de comparación externa obenchmarkingidentifican buenas prácticas en organizaciones similares. En servicios de salud pública, obtener indicadores de este tipo no es fácil. Los objetivos de este trabajo son describir el proceso seguido para llevar a cabo un ejercicio debenchmarkingen una organización de salud pública, y compartir sus frutos. Para ello, se identificaron organizaciones para compararlas, y se buscaron en sus páginas web informes o memorias con indicadores de las actividades o resultados de los servicios de salud pública. Se identificaron limitaciones y condicionantes de los indicadores de las diferentes organizaciones, así como maneras de mejorar su capacidad de comparación. Finalmente, se propone un conjunto de 19 indicadores como núcleo inicial de comparación orientado a la gestión de calidad. (AU)

Continuous management improvement should be an aspiration for all public sector organizations. External comparison or benchmarking identifies good practices in similar organizations. For public health services, it is not easy to obtain such indicators. The objectives of this paper are to describe the process of conducting a benchmarking exercise for a public health agency, and to share its results. For this purpose, agencies that may be compared were identified, and their websites were searched for annual reports or other documents with indicators of the activities or results of public health services. Limitations and contextual aspects of the indicators of the different organizations were identified, as well as ways to improve their comparability. Finally, a set of 19 indicators is proposed, as an initial core for quality management comparisons. (AU)

Un sistema de vigilancia de salud pública para el cambio climático en las ciudades / A public health surveillance system applied to climate change for cities

Se presenta una primera propuesta de sistema de vigilancia de salud pública aplicado al cambio climático en el contexto urbano, y el proceso que llevó a su definición. Tras varios años de seguimiento de los diversos aspectos del cambio climático y de su impacto, desde los servicios de salud pública de Barcelona se formuló una propuesta preliminar y se reunió un grupo de trabajo de personas expertas que discutieron y valoraron su contenido. Se partió de cuatro categorías de componentes: datos de clima, impactos en salud del cambio climático y sus determinantes, contribuciones de la ciudad a la mitigación (especialmente con cobeneficios para la salud) y acciones para reducir la vulnerabilidad ante eventos extremos. Se desglosaron en 12 componentes, con indicadores para cada uno. El esquema se refinó con aportaciones posteriores y se ha incorporado al trabajo de los servicios de salud pública de la ciudad implicados en este campo. (AU)

This paper makes a first proposal for a public health surveillance system for climate change in cities, and describes the process that led to its definition. After several years of monitoring different aspects related to climate change and its impact, the public health services of Barcelona made a preliminary proposal and gathered a working group of experts to discuss and review it. Four categories of components were defined: climate data, health impacts of climate change and its determinants, contributions of the city to mitigation (especially those with health co-benefits), and actions to reduce vulnerability to extreme events. They were broken in twelve components, with indicators for each. The proposal was further refined with subsequent reviews, and is being used by the city public health services involved in this field.

Mejorando el control del riesgo por alergias e intolerancias alimentarias en los comedores escolares: aportaciones cualitativas de los grupos focales / Improving the control of food allergy and intolerance risks in school settings: qualitative inputs from focus groups

Este trabajo describe la aplicación de la técnica de grupos focales a la evaluación de los programas de control de riesgos por alergias e intolerancias alimentarias (AIA) en los comedores escolares de Barcelona. Tras impulsar su implantación, y como un componente cualitativo de su evaluación, los servicios de salud pública realizaron dos grupos focales, uno con personas procedentes de escuelas que gestionan su propia cocina y otro con personas de empresas externas que gestionan este servicio. Participaron 28 personas de un 46% de los centros invitados. Todas las escuelas parecen haber implantado un programa de autocontrol de AIA. Aunque las empresas gestoras externas solían contar ya con él, la mayoría de las escuelas que gestionan su propia cocina no lo tenía y adoptó el programa propuesto por los servicios de salud pública. El número de escolares con alguna AIA notificada disminuyó tras el programa, al exigir este un mayor rigor en su documentación

This paper describes the use of focus groups as part of the evaluation of programmes to control food allergy and intolerance (FAI) in school settings in the city of Barcelona (Spain). After fostering their adoption and as a qualitative component of their evaluation, the public health services ran two focus groups, one with people from schools that manage their own kitchen, and another from companies that outsource this service. There were 28 participants from 46% of the centres invited. All the schools seem to have implemented a self-control programme on FAI. Although outsourcing companies already had a programme, the schools that managed their own service mostly adopted the programme promoted by the public health services. The number of schoolchildren with reported FAI reduced after the programme, as it required more rigorous documentation from families

Estar atentos, estar dispuestos / To be aware, to be willing to

Al cumplirse cien años del aún vigente “Informe Flexner” los educadores de las ciencias de la salud de todo el mundo generaron reflexiones y nuevas metas para las mismas. Son muchos los cambios producidos desde la presentación de Abraham Flexner en 1910 pero muy importantes son los ocurridos sobre el fin del siglo XX. La aparición de las tecnologías de la información y de la comunicación fueron precipitantes. Este ensayo pretende dar muestra de la evolución y alertar que esa combinación nos obliga a los docentes a estar informados y atentos a su influencia en el ámbito de la educación superior y entender que debemos estar dispuestos a cambios personales y a brindar una mayor colaboración para producir los cambios institucionales que nos permitan entregar a la sociedad mejores egresados.

To celebrate one hundred years of the still current "Flexner report" worldwide health science educators generated reflections and new goals for them. There have been many changes since the submission of Abraham Flexner in 1910 but more important are the ones which took place at the end of the 20th century. The emergence of information and communication technologies were swift. This essay is intended to alert that that combination forces us teachers to be informed and aware of its influence in the field of higher education and understand that we must be prepared to personal changes and to provide greater collaboration to produce the institutional enabling us to deliver better graduates to society.

[Advances in the management of an animal shelter]. / Avances en la gestión de un centro de acogida de animales de compañía.

Changes in the Barcelona animal shelter from 2002 to 2005 are presented. In 2003, routine euthanasia of unclaimed stray animals was discontinued, due to a political decision of the city council. Changes were also made in the management of the shelter: from January 2003 to July 2004 the shelter was operated by an animal protection organization, and then directly again by the city public health agency. Management of the shelter by the animal welfare organization was associated with an increase in the proportion of dogs rescued and adopted. The suspension of routine euthanasia was associated with a marked increase in the number of stray dogs. Canine distemper became endemic in the shelter until late 2004, due to a certain unwillingness to use euthanasia to control infection transmission. Direct operation by public health services in a context of transparency and high social expectations has led to the development and adoption of standardized work protocols in the shelter, improving quality.

Avances en la gestión de un centro de acogida de animales de compañía / Advances in the management of an animal shelter

Se presenta la evolución del centro de acogida de animales de compañía de la ciudad de Barcelona de 2002 a 2005. Por mandato municipal se suspenden de forma general los sacrificios desde 2003. Se producen cambios de gestión, asumida durante los meses que van de enero de 2003 a julio de 2004 por una entidad protectora, y luego directamente por los servicios de salud pública. La gestión de una protectora conllevó notables incrementos en el número de animales rescatados y adoptados. La suspensión del sacrificio se acompañó de un extraordinario incremento de la tasa de abandonos. La reticencia en eutanasiar a animales aquejados de enfermedades infecciosas generó una endemia de moquillo, que se controló a finales de 2004. La recuperación de la gestión directa por los servicios de salud pública en un contexto de transparencia y exigencia social ha llevado al desarrollo y la adopción de protocolos de trabajo sistematizados, que mejoran la calidad

Resultados de la cirugía y la angioplastia percutánea transluminar en la hipertensión renovascular / Results of surgery and percutaneous transluminal angioplasty of renovascular hypertension

Se evaluaron los resultados del tratamiento con cirugía y angioplastia percutánea transluminal de la arteria renal en 63 pacientes adultos de ambos sexos, de 16 a 60 años de edad, con hipertensión renovascular debida displasia fibromuscular en 48 y a ateroesclerosis en 15. La estenosis de la arteria renal fue unilateral en 47 pacientes y bilateral en 16. Los procedimientos quirúrgicos utilizados más frecuentemente fueron el puente aorto-renal con injerto de safena en 22 pacientes y la nefrectomía unilateral en 16. De 41 pacientes tratados con cirugía, se obtuvo curación o mejoría de la hipertensión arterial después de un año en 30 (73.1 por ciento). De 22 pacientes tratados con angioplastia se obtuvo curación o mejoría en 17 (77.2 por ciento). Los resultados fueron satisfactorios en los pacientes con displasia fibromuscular y estenosis unilateral, y pobres en ateroesclerosis y estenosis bilateral con ambos métodos. Se conculye que la cirugía y la angioplastia son métodos terapéuticos satisfactorios en la hipertensión renovascular, principalmente cuando es unilateral y debida a displasia fibromuscular
