El papel del clero en la expulsión de los jesuitas decretada por Carlos III en 1767

El presente trabajo trata sobre la reacción del clero secular y regular ante la expulsión de los jesuitas de la monarquía hispánica en 1767. Veremos las opiniones de algunos de los obispos favorables a la política regalista de Carlos III, y cómo actuaron antes la operación mejor diseñada y más eficaz contra la Compañía de Jesús en los amplios territorios del monarca Borbón. Al mismo tiempo, analizaremos los comentarios de los propios expulsos sobre el clero español y las consecuencias que tuvieron ambas reacciones.

Perceived sexism as a health determinant in Spain

OBJECTIVES: The goals of the present study are to explore the association between perceived sexism and self-perceived health, health-related behaviors, and unmet medical care needs among women in Spain; to analyze whether higher levels of discrimination are associated with higher prevalence of poor health indicators and to examine whether these relationships are modified by country of origin and social class. MATERIALS AND METHODS: The study is based on a cross-sectional design using data from the 2006 Spanish Health Interview Survey. We included women aged 20-64 years (n = 10,927). Six dependent variables were examined: four of health (self-perceived health, mental health, hypertension, and having had an injury during the previous year), one health behavior (smoking), and another related to the use of the health services (unmet need for medical care). Perceived sexism was the main independent variable. Social class and country of origin were considered as effect modifiers. We obtained the prevalence of perceived sexism. Logistic regression models, adjusted for potential confounders, were fitted to study the association between sexism and poor health outcomes. Results: The prevalence of perceived sexism was 3.4%. Perceived sexism showed positive and consistent associations with four poor health outcomes (poor self-perceived health, poor mental health, injuries in the last 12 months, and smoking). The strength of these associations increased with increased scores for perceived sexism, and the patterns were found to be modified by country of origin and social class. CONCLUSION: This study shows a consistent association between perceived sexism and poor health outcomes in a country of southern Europe with a strong patriarchal tradition.

Mapping the awareness of inequalities in health programs in Spanish communities: moving forward together

The aim of this study is to map the awareness of gender, socioeconomic, immigrant and ethnic health inequalities in health at schools, maternal health and traffic injury health prevention programs. The study was conducted in the 19 health descentralized areas in Spain, 17 autonomous community (ACs) and the 2 autonomous cities (ACities). The data were collected from May 2008 to January 2009. The unit of analysis was the collection of policy documents setting out the programs mentioned above and the related support material in each AC. A reading guide was used to analyze the awareness of inequalities. With regard to health at schools, 2 of 10 programs show a high awareness of inequalities and include many specific proposals to be implemented at the local level. Regarding maternal health, 13 ACs have prepared support material with high awareness of inequalities to be implemented. A traffic injury program has been created in two ACs. We map the whole situation in Spain regarding the health programs that we have used as examples and their awareness of inequalities. We can conclude that there are differences between the regions studied in Spain and in general, the awareness of inequalities is low.

Estado de salud y demanda de servicios de salud de la población ecuatoriana en España

Análisis del estado de salud y del grado de acceso a los servicios de salud de los inmigrantes ecuatorianos en la provincia de Alicante. La finalidad es descriptiva y práctica: realizar un diagnóstico comunitario de salud básico y una aproximación al nivel de demanda de los servicios sanitarios. El análisis se centra en la evaluación de la hipótesis del inmigrante sano, pero vulnerable, y en el tipo de consumo de servicios de salud realizado. Para valorar esta hipótesis se ha procedido a comparar los datos obtenidos en una encuesta a población ecuatoriana residente en la provincia de Alicante, con los de la última Encuesta Nacional de Salud 2003 y el PHOGUE (2000). Los resultados indican que el estado de salud de la población ecuatoriana es similar al de la población española que participa en el mismo mercado de trabajo que la inmigración económica (trabajadores con baja cualificación), aunque se observan algunos elementos de vulnerabilidad (en especial, en términos de salud emocional).

Los impactos de los cuidados de salud en los ámbitos de vida de las personas cuidadoras

El objetivo del artículo es analizar la distribución del tiempo de las personas cuidadoras en las distintas esferas de la vida (la esfera laboral, la privada o personal y la doméstica). El estudio se basa en el análisis de los datos de la Encuesta de Empleo del Tiempo 2002-2003 del Instituto Nacional de Estadística (INE). Los resultados de la investigación muestran los impactos negativos del cuidado informal sobre los distintos ámbitos de la vida en términos de reducción de la vida privada o personal, de la participación en el ámbito laboral y de mayor carga del trabajo total. Asimismo, también ponen de manifiesto la heterogeneidad de los efectos del cuidado informal en la vida cotidiana de las personas cuidadoras según el sexo, la edad y el nivel de ingresos.

Relación entre el número de horas de cuidado informal y el estado de salud mental de las personas cuidadoras

Fundamento: La salud mental de las personas cuidadoras se ve perjudicada por las tareas de cuidado. Son necesarios estudios que especifiquen la influencia de diversas variables en la asociación entre cuidado informal y salud mental. El objetivo del trabajo es analizar los efectos del tiempo dedicado al cuidado informal en la salud mental por sexo según el tipo de personas dependientes. Métodos: Los datos que se utilizaron fueron los de la Encuesta Nacional de Salud 2006, cuya muestra estaba compuesta por 29.478 participantes. Variables: salud mental (GHQ-12), tiempo de cuidado, edad, clase social y apoyo funcional (Duke-UNC). Se realizó análisis de regresión logística para determinar la probabilidad de contar con mala salud mental según horas de cuidado, ajustado por edad, clase social y apoyo funcional. Resultados: Las mujeres presentan peor salud mental a partir de 97 horas semanales en el cuidado a menores (OR=1,372), de 25 horas en el cuidado a personas mayores de 74 años (OR=1,602 entre 25 y 48 horas; OR=1,467 49-96h; OR=1,874 97-168h) y cuando dedican alguna hora al cuidado de personas adultas con discapacidad (OR=1,996 0-24h; OR=2,507 25-48h; OR=3,016 49-96h; OR=1,651 97-168h). Los varones muestran deterioro de la salud psicológica cuando dedican un elevado número de horas al cuidado de personas mayores de 74 años (OR=2,810 97168h.) y personas con discapacidad (OR=3,411 97-168h.) y cuando dedican de 0 a 24h al cuidado de menores (OR=1,595). Conclusiones: El efecto del número de horas de cuidado en la salud mental de las personas cuidadoras está influido por el tipo de persona dependiente y por el sexo de la persona cuidadora.

¿Está ayudando la cooperación española a conseguir los Objetivos de Desarrollo del Milenio?

La Declaración del Milenio del año 2000 constituye el acuerdo internacional con mayor consenso político de la historia, apoyado por Naciones Unidas y los gobiernos de 191 países.1 Los Objetivos de Desarrollo del Milenio son fruto de este acuerdo y constituyen un programa operativo formado por tres objetivos de salud, como son la reducción de la mortalidad infantil, de la mortalidad materna y de las enfermedades infecciosas, y cinco orientados a determinantes de la salud, como la pobreza, la educación, la igualdad de género, el medio ambiente y diversos factores políticos y económicos. Puesto que el límite para cumplir con estos objetivos se estableció en el año 2015, es pertinente examinar en este momento las políticas de los gobiernos para comprobar cuál ha sido su contribución al proyecto.2 El objetivo de este editorial es, en concreto, explorar si la política de cooperación española para el desarrollo está contribuyendo al alcance de los Objetivos de Desarrollo del Milenio.

Tauroursodeoxycholic acid prevents retinal degeneration in transgenic P23H rats

Purpose. To evaluate the preventive effect of tauroursodeoxycholic acid (TUDCA) on photoreceptor degeneration, synaptic connectivity and functional activity of the retina in the transgenic P23H rat, an animal model of autosomal dominant retinitis pigmentosa (RP). Methods. P23H line-3 rats were injected with TUDCA once a week from postnatal day (P)21 to P120, in parallel with vehicle-administered controls. At P120, functional activity of the retina was evaluated by electroretinographic (ERG) recording. The effects of TUDCA on the number, morphology, integrity, and synaptic connectivity of retinal cells were characterized by immunofluorescence confocal microscopy. Results. The amplitude of ERG a- and b-waves was significantly higher in TUDCA-treated animals under both scotopic and photopic conditions than in control animals. In the central area of the retina, TUDCA-treated P23H rats showed threefold more photoreceptors than control animals. The number of TUNEL-positive cells was significantly smaller in TUDCA-treated rats, in which photoreceptor morphology was preserved. Presynaptic and postsynaptic elements, as well as the synaptic contacts between photoreceptors and bipolar or horizontal cells, were preserved in TUDCA-treated P23H rats. Furthermore, in TUDCA-treated rat retinas, the number of both rod bipolar and horizontal cell bodies, as well as the density of their synaptic terminals in the outer plexiform layer, was greater than in control rats. Conclusions. TUDCA treatment was capable of preserving cone and rod structure and function, together with their contacts with their postsynaptic neurons. The neuroprotective effects of TUDCA make this compound potentially useful for delaying retinal degeneration in RP.

Rotenone induces degeneration of photoreceptors and impairs the dopaminergic system in the rat retina

Rotenone is a widely used pesticide and a potent inhibitor of mitochondrial complex I (NADH-quinone reductase) that elicits the degeneration of dopaminergic neurons and thereby the appearance of a parkinsonian syndrome. Here we have addressed the alterations induced by rotenone at the functional, morphological and molecular levels in the retina, including those involving both dopaminergic and non-dopaminergic retinal neurons. Rotenone-treated rats showed abnormalities in equilibrium, postural instability and involuntary movements. In their outer retina we observed a loss of photoreceptors, and a reduced synaptic connectivity between those remaining and their postsynaptic neurons. A dramatic loss of mitochondria was observed in the inner segments, as well as in the axon terminals of photoreceptors. In the inner retina we observed a decrease in the expression of dopaminergic cell molecular markers, including loss of tyrosine hydroxylase immunoreactivity, associated with a reduction of the dopaminergic plexus and cell bodies. An increase in immunoreactivity of AII amacrine cells for parvalbumin, a Ca2+-scavenging protein, was also detected. These abnormalities were accompanied by a decrease in the amplitude of scotopic and photopic a- and b-waves and an increase in the b-wave implicit time, as well as by a lower amplitude and greater latency in oscillatory potentials. These results indicate that rotenone induces loss of vision by promoting photoreceptor cell death and impairment of the dopaminergic retinal system.

Time course modifications in organotypic culture of human neuroretina

The purpose of this study was to characterize organ culture of human neuroretina and to establish survival and early degeneration patterns of neural and glial cells. Sixteen neuroretina explants were prepared from 2 postmortem eyes of 2 individuals. Four explants were used as fresh retina controls, and 12 were evaluated at 3, 6, and 9 days of culture. Neuroretina explants (5 × 5 mm) were cultured in Transwell® dishes with the photoreceptor layer facing the supporting membrane. Culture medium (Neurobasal A-based) was maintained in contact with the membrane beneath the explant. Cryostat and ultrathin sections were prepared for immunohistochemistry and electron microscopy. Neuroretinal modifications were evaluated after toluidine blue staining and after immunostaining for neuronal and glial cell markers. Ultrastructural changes were analyzed by electron microscopy. From 0 to 9 days in culture, there was progressive retinal degeneration, including early pyknosis of photoreceptor nuclei, cellular vacuolization in the ganglion cell layer, decrease of both plexiform layer thicknesses, disruption and truncation of photoreceptor outer segments (OS), and marked reduction in the number of nuclei at both nuclear layers where the cells were less densely packed. At 3 days there was swelling of cone OS with impairment of pedicles, loss of axons and dendrites of horizontal and rod bipolar cells that stained for calbindin (CB) and protein kinase C (PKC-α), respectively. After 9 days, horizontal cells were pyknotic and without terminal tips. There were similar degenerative processes in the outer plexiform layer for rod bipolar cells and loss of axon terminal lateral varicosities in the inner plexiform layer. Glial fibrillary acidic protein (GFAP) staining did not reveal a dramatic increase of gliosis in Müller cells. However, some Müller cells were CB immunoreactive at 6 days of culture. Over 9 days of culture, human neuroretina explants underwent morphological changes in photoreceptors, particularly the OS and axon terminals, and in postsynaptic horizontal and bipolar cells. These early changes, not previously described in cultured human samples, reproduce some celullar modifications after retinal damage. Thus, this model may be suitable to evaluate therapeutic agents during retinal degeneration processes.

Integración cultural de los jesuitas hispanos desterrados y su rastro en las iglesias boloñesas

En este artículo estudiamos la integración de los jesuitas desterrados de los territorios de Carlos III, concretamente de los que pertenecían a las Provincias de Castilla y México, a lo largo de su destierro en Bolonia. Observamos, en una primera parte, su día a día, desde que llegaron hasta su instalación definitiva y los iniciales enfrentamientos con sus hermanos: los jesuitas italianos, para analizar después, la huella devocional y personal que nos han legado y que hemos rastreado en alguno de los archivos parroquiales de esta ciudad.

Social determinants of self-perceived discrimination in Spain

Objectives: To analyse the association between self-perceived discrimination and social determinants (social class, gender, country of origin) in Spain, and further to describe contextual factors which contribute to self-perceived discrimination. Methods: Cross-sectional design using data from the Spanish National Health Survey (2006). The dependent variable was self-perceived discrimination, and independent and stratifying variables were sociodemographic characteristics (e.g. sex, social class, country of origin, educational level). Logistic regression was used. Results: The prevalence of self-perceived discrimination was 4.2% for men and 6.3% for women. The likelihood of self-perceived discrimination was higher in people who originated from low-income countries: men, odds ratio (OR) 5.59 [95% confidence interval (CI) 4.55–6.87]; women, OR 4.06 (95% CI 3.42–4.83). Women were more likely to report self-perceived discrimination by their partner at home than men [OR 8.35 (95% CI 4.70–14.84)]. The likelihood of self-perceived discrimination when seeking work was higher among people who originated from low-income countries than their Spanish counterparts: men, OR 13.65 (95% CI 9.62–19.35); women, OR 10.64 (95% CI 8.31–13.62). In comparison with Spaniards, male white-collar workers who originated from low-income countries [OR 11.93 (95% CI 8.26–17.23)] and female blue-collar workers who originated from low-income countries (OR 1.6 (95% CI 1.08–2.39)] reported higher levels of self-perceived discrimination. Conclusions: Self-perceived discrimination is distributed unevenly in Spain and interacts with social inequalities. This particularly affects women and immigrants.

The ubiquitin-proteasome system in retinal health and disease

The ubiquitin–proteasome system (UPS) is the main intracellular pathway for modulated protein turnover, playing an important role in the maintenance of cellular homeostasis. It also exerts a protein quality control through degradation of oxidized, mutant, denatured, or misfolded proteins and is involved in many biological processes where protein level regulation is necessary. This system allows the cell to modulate its protein expression pattern in response to changing physiological conditions and provides a critical protective role in health and disease. Impairments of UPS function in the central nervous system (CNS) underlie an increasing number of genetic and idiopathic diseases, many of which affect the retina. Current knowledge on the UPS composition and function in this tissue, however, is scarce and dispersed. This review focuses on UPS elements reported in the retina, including ubiquitinating and deubiquitinating enzymes (DUBs), and alternative proteasome assemblies. Known and inferred roles of protein ubiquitination, and of the related, SUMO conjugation (SUMOylation) process, in normal retinal development and adult homeostasis are addressed, including modulation of the visual cycle and response to retinal stress and injury. Additionally, the relationship between UPS dysfunction and human neurodegenerative disorders affecting the retina, including Alzheimer's, Parkinson's, and Huntington's diseases, are dealt with, together with numerous instances of retina-specific illnesses with UPS involvement, such as retinitis pigmentosa, macular degenerations, glaucoma, diabetic retinopathy (DR), and aging-related impairments. This information, though still basic and limited, constitutes a suitable framework to be expanded in incoming years and should prove orientative toward future therapy design targeting sight-affecting diseases with a UPS underlying basis.

RNA-Seq expression profile of genes related to neurodegenerative disorders affecting the human retina

Human neurodegenerative diseases, such as Parkinson’s disease (PD) and the neuromuscular disorders called dystroglycanopathies (DGPs), cause retinal impairments. We have used RNA-Seq technology to catalog all known genes linked to PD and DGPs expressed in the human retina and quantitate their mRNA levels in terms of FPKM. We have also characterized their expression profiles in the retina by determining their exonic, intronic and exon-intron junction expression levels, as well as the alternative splicing pattern of particular genes. We believe these data could pave the way toward understanding the molecular bases of sight deficiencies associated with neurodegenerative disorders.

Alterations in energy metabolism, neuroprotection and visual signal transduction in the retina of parkinsonian, MPTP-treated monkeys

Parkinson disease is mainly characterized by the degeneration of dopaminergic neurons in the central nervous system, including the retina. Different interrelated molecular mechanisms underlying Parkinson disease-associated neuronal death have been put forward in the brain, including oxidative stress and mitochondrial dysfunction. Systemic injection of the proneurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) to monkeys elicits the appearance of a parkinsonian syndrome, including morphological and functional impairments in the retina. However, the intracellular events leading to derangement of dopaminergic and other retinal neurons in MPTP-treated animal models have not been so far investigated. Here we have used a comparative proteomics approach to identify proteins differentially expressed in the retina of MPTP-treated monkeys. Proteins were solubilized from the neural retinas of control and MPTP-treated animals, labelled separately with two different cyanine fluorophores and run pairwise on 2D DIGE gels. Out of >700 protein spots resolved and quantified, 36 were found to exhibit statistically significant differences in their expression levels, of at least ±1.4-fold, in the parkinsonian monkey retina compared with controls. Most of these spots were excised from preparative 2D gels, trypsinized and subjected to MALDI-TOF MS and LC-MS/MS analyses. Data obtained were used for protein sequence database interrogation, and 15 different proteins were successfully identified, of which 13 were underexpressed and 2 overexpressed. These proteins were involved in key cellular functional pathways such as glycolysis and mitochondrial electron transport, neuronal protection against stress and survival, and phototransduction processes. These functional categories underscore that alterations in energy metabolism, neuroprotective mechanisms and signal transduction are involved in MPTPinduced neuronal degeneration in the retina, in similarity to mechanisms thought to underlie neuronal death in the Parkinson’s diseased brain and neurodegenerative diseases of the retina proper.
