Area deprivation and mortality in the provincial capital cities of Andalusia and Catalonia (Spain)

Objective: To study the linkage between material deprivation and mortality from all causes, for men and women separately, in the capital cities of the provinces in Andalusia and Catalonia (Spain). Methods: A small-area ecological study was devised using the census section as the unit for analysis. 188 983 Deaths occurring in the capital cities of the Andalusian provinces and 109 478 deaths recorded in the Catalan capital cities were examined. Principal components factorial analysis was used to devise a material deprivation index comprising the percentage of manual labourers, unemployment and illiteracy. A hierarchical Bayesian model was used to study the relationship between mortality and area deprivation. Main results: In most cities, results show an increased male mortality risk in the most deprived areas in relation to the least depressed. In Andalusia, the relative risks between the highest and lowest deprivation decile ranged from 1.24 (Malaga) to 1.40 (Granada), with 95% credibility intervals showing a significant excess risk. In Catalonia, relative risks ranged between 1.08 (Girona) and 1.50 (Tarragona). No evidence was found for an excess of female mortality in most deprived areas in either of the autonomous communities. Conclusions: Within cities, gender-related differences were revealed when deprivation was correlated geographically with mortality rates. These differences were found from an ecological perspective. Further research is needed in order to validate these results from an individual approach. The idea to be analysed is to identify those factors that explain these differences at an individual level.

Morbilidad psíquica, existencia de diagnóstico y consumo de psicofármacos. Diferencias por comunidades autónomas según la Encuesta Nacional de Salud de 2006

Background: Most of the studies on sychological distress in Spain have been conducted in small geographical areas or specific population groups. However, there are no studies that provide representative data for each Autonomous Community (AC). The objectives of this paper are to determine, both in Spain and in the AC, the prevalence of psychological distress, diagnosis, use of psychoactive medication, social support and self-perceived health, as well as to study the association between psychological distress and the rest of the variables. Methods: Cross-sectional study, using data from the 2006 National Health Survey, that was completed by 29,478 persons. Variables studied: sociodemographics, psychological distress (GHQ-12), self-perceived health, mental disorder diagnosis, functional social support (Duke) and use and prescription of psychoactive medication. Results: The prevalence of psychological distress in Spain was 20,1%; the highest prevalence was found in Canary Islands (28,2%) and the lowest in La Rioja (12,2%). Among those who presented psychological distress, 62,4% had never received a mental disorder diagnosis, and 71,6% had not used psychoactive medication in the last year. The highest prevalences of non-diagnosed cases (81,8%) and cases non-treated with psychoactive medication (83,1%) were found in La Rioja, whereas the lowest prevalences were found in Asturias. Eight percent of the persons who presented psychological distress had low social support and 63,8% reported bad self-perceived health. Conclusions: Psychological distress is a prevalent phenomenon, and more than half of the persons who suffer it receive neither a diagnosis nor psychoactive medication. Moreover, there are considerable differences between the AC.

The andalusian comprehensive cancer plan 2002-2006 : Andalusian Public Health System

Cancer is a major health problem in our Autonomous Community and is the second cause of death in both males and females. The incidence, mortality, potential years of life lost and resource consumption alongside the suffering endured by patients and families call for a commitment to be made by the Health Administration, healthcare professionals, patients and caregivers. This Plan is based on updated analyses of the mortality, incidence and survival of Cancer in Andalusia, of the situation of Cancer care and the resources available and of the expectations of patients and main caregivers, and on the conclusions of different Work Groups on the Management of Processes related to Cancer. The Andalusian Comprehensive Cancer Plan establishes an action programme that involves organisational and functional changes, new proposals for the training of professionals and a specific funding base.

5-Fluorouracil-loaded poly(ε-caprolactone) nanoparticles combined with phage E gene therapy as a new strategy against colon cancer

This work aimed to develop a new therapeutic approach to increase the efficacy of 5-fluorouracil (5-FU) in the treatment of advanced or recurrent colon cancer. 5-FU-loaded biodegradable poly(ε-caprolactone) nanoparticles (PCL NPs) were combined with the cytotoxic suicide gene E (combined therapy). The SW480 human cancer cell line was used to assay the combined therapeutic strategy. This cell line was established from a primary adenocarcinoma of the colon and is characterized by an intrinsically high resistance to apoptosis that correlates with its resistance to 5-FU. 5-FU was absorbed into the matrix of the PCL NPs during synthesis using the interfacial polymer disposition method. The antitumor activity of gene E from the phage ϕX174 was tested by generating a stable clone (SW480/12/E). In addition, the localization of E protein and its activity in mitochondria were analyzed. We found that the incorporation of 5-FU into PCL NPs (which show no cytotoxicity alone), significantly improved the drug's anticancer activity, reducing the proliferation rate of colon cancer cells by up to 40-fold when compared with the nonincorporated drug alone. Furthermore, E gene expression sensitized colon cancer cells to the cytotoxic action of the 5-FU-based nanomedicine. Our findings demonstrate that despite the inherent resistance of SW480 to apoptosis, E gene activity is mediated by an apoptotic phenomenon that includes modulation of caspase-9 and caspase-3 expression and intense mitochondrial damage. Finally, a strongly synergistic antiproliferative effect was observed in colon cancer cells when E gene expression was combined with the activity of the 5-FU-loaded PCL NPs, thereby indicating the potential therapeutic value of the combined therapy.

Use of palliative radiotherapy in brain and bone metastases (VARA II study).

INTRODUCTION Metastases are detected in 20% of patients with solid tumours at diagnosis and a further 30% after diagnosis. Radiation therapy (RT) has proven effective in bone (BM) and brain (BrM) metastases. The objective of this study was to analyze the variability of RT utilization rates in clinical practice and the accessibility to medical technology in our region. PATIENTS AND METHODS We reviewed the clinical records and RT treatment sheets of all patients undergoing RT for BM and/or BrM during 2007 in the 12 public hospitals in an autonomous region of Spain. Data were gathered on hospital type, patient type and RT treatment characteristics. Calculation of the rate of RT use was based on the cancer incidence and the number of RT treatments for BM, BrM and all cancer sites. RESULTS Out of the 9319 patients undergoing RT during 2007 for cancer at any site, 1242 (13.3%; inter-hospital range, 26.3%) received RT for BM (n = 744) or BrM (n = 498). These 1242 patients represented 79% of all RT treatments with palliative intent, and the most frequent primary tumours were in lung, breast, prostate or digestive system. No significant difference between BM and BrM groups were observed in: mean age (62 vs. 59 yrs, respectively); gender (approximately 64% male and 36% female in both); performance status (ECOG 0-1 in 70 vs. 71%); or mean distance from hospital (36 vs. 28.6 km) or time from consultation to RT treatment (13 vs. 14.3 days). RT regimens differed among hospitals and between patient groups: 10 × 300 cGy, 5 × 400 cGy and 1x800cGy were applied in 32, 27 and 25%, respectively, of BM patients, whereas 10 × 300cGy was used in 49% of BrM patients. CONCLUSIONS Palliative RT use in BM and BrM is high and close to the expected rate, unlike the global rate of RT application for all cancers in our setting. Differences in RT schedules among hospitals may reflect variability in clinical practice among the medical teams.

El futuro de la sanidad ambiental en Andalucía: oportunidades de mejora.

In the present article is presented a portrait of the situation of the environmental health in the administration of Andalusian Goverment; are analyzed implanted management formulations and we believe a reflection space on the professional exercise and the course begun with the organizational process in the Andalusian public health. The public health system has not undergone reconstruction from the process of transferences from the State towards the autonomous Communities. We identified the extrapolation of the model clinicalassistance management to the public health structures without delving what is sufficient in their organization and objectives. Setting of business process management (BMP) has got worse the administrative bureaucracy and the teamwork has not been preceded of alliances and agreements that generate feeling of ownership the same organization to avoid professional conflicts. We bet on strengthening the paper of the environmental health technicians as referring in the identification of this performances within public health system. For this propose we need the implication of all the professionals in the reform of the organization and management of the health public, to evolve in the professional exercise creating a regulated academic specialty and to define the competences maps in their different capabilites areas.

Sensitization to Anisakis simplex species in the population of northern Morocco.

OBJECTIVE To investigate sensitization to third-stage Anisakis simplex larvae in a randomly selected population in northern Morocco. METHODS We studied sera obtained from clinical analysis laboratories in Tangier and Tetuouan and from fishermen at Tangier port. The age of the study population ranged from 6 to 83 years. ImmunoCAP and immunoblotting techniques were used to determine total and specific immunoglobulin (Ig) E values and the chi2 and Fisher exact tests were applied to analyze relationships between study variables. RESULTS A seroprevalence of 5.1% was found, with a higher percentage of positive sera in the 31-to-43-year age group. Sensitization was not significantly associated with the origin, sex, occupation, or age of the individuals studied. In sera positive by InmunoCAP, immunoblotting studies detected numerous bands of between 7 kDa and >209 kDa, with a predominance of bands in the approximately 20-kDa to 24-kDa range. CONCLUSIONS Although no cases of human anisakiasis have been reported in Morocco to date, part of a randomly selected population in Northern Morocco shows sensitization to A simplex proteins.

National Health System Virtual Library Viability Project (Spain)

Introduction: The ICT progress and development are making the set up of virtual libraries easier, with great advantages for users in terms of immediate access to vast amounts of library information, online resources, and services. Most of the Autonomous Spanish Regions are presently working on the establishment of virtual libraries with the aim of optimising economic resources destined to subscribe bibliographic information sources and offering qualified documentary services to Public Health System Professionals. The Ministry of Health and Social Policy, an institution unifying health matters, issued this Project to study the National Health System Virtual Library creation viability, in order to guarantee relevant scientific information access equity. Objectives: - To study the National Health System (NHS) Virtual Library set up viability. - To elaborate the Spanish territory health information resource map. - To identify the appropriate technological model. - To identify the documentary services to be offered. - To identify the more optimum functional, structural model. - To identify the economic model. Method: - To create a chart organization for the project´s management. - To organize Work groups. - To elaborate a standardised survey model for the libraries of the autonomous regions. Results: - Identification of the different Autonomous Region libraries of health models. - Recommendations for the NHS Virtual Library: - Functional, structural model - Technological model - Financial-economic model Conclusions: The fact that the Virtual Library would be an invaluable space for access to quality scientific information, as well as that the minimum services could be offered to every NHS user regardless of geographical situation, is confirmed. Accordingly, we thought about three different models to develop the Virtual Library, depending on this initial analysis, which will allow us to establish the most suitable model for the Spanish National Health System, considering its economic, functional and technological recommendations. It would be necessary to do a study for the NHS Virtual Library Set Up following the recommendations arising from this Project.

Diets based on virgin olive oil or fish oil but not on sunflower oil prevent age-related alveolar bone resorption by mitochondrial-related mechanisms.

BACKGROUND/OBJECTIVES Aging enhances frequency of chronic diseases like cardiovascular diseases or periodontitis. Here we reproduced an age-dependent model of the periodontium, a fully physiological approach to periodontal conditions, to evaluate the impact of dietary fat type on gingival tissue of young (6 months old) and old (24 months old) rats. METHODS/FINDINGS Animals were fed life-long on diets based on monounsaturated fatty acids (MUFA) as virgin olive oil, n-6 polyunsaturated fatty acids (n-6PUFA), as sunflower oil, or n-3PUFA, as fish oil. Age-related alveolar bone loss was higher in n-6PUFA fed rats, probably as a consequence of the ablation of the cell capacity to adapt to aging. Gene expression analysis suggests that MUFA or n-3PUFA allowed mitochondria to maintain an adequate turnover through induction of biogenesis, autophagy and the antioxidant systems, and avoiding mitochondrial electron transport system alterations. CONCLUSIONS The main finding is that the enhanced alveolar bone loss associated to age may be targeted by an appropriate dietary treatment. The mechanisms involved in this phenomenon are related with an ablation of the cell capacity to adapt to aging. Thus, MUFA or n-3PUFA might allow mitochondrial maintaining turnover through biogenesis or autophagy. They might also be able to induce the corresponding antioxidant systems to counteract age-related oxidative stress, and do not inhibit mitochondrial electron transport chain. From the nutritional and clinical point of view, it is noteworthy that the potential treatments to attenuate alveolar bone loss (a feature of periodontal disease) associated to age could be similar to some of the proposed for the prevention and treatment of cardiovascular diseases, a group of pathologies recently associated with age-related periodontitis.

Pattern of use of radiotherapy for lung cancer: a descriptive study.

BACKGROUND Lung cancer remains one of the most prevalent forms of cancer. Radiotherapy, with or without other therapeutic modalities, is an effective treatment. Our objective was to report on the use of radiotherapy for lung cancer, its variability in our region, and to compare our results with the previous study done in 2004 (VARA-I) in our region and with other published data. METHODS We reviewed the clinical records and radiotherapy treatment sheets of all patients undergoing radiotherapy for lung cancer during 2007 in the 12 public hospitals in Andalusia, an autonomous region of Spain. Data were gathered on hospital, patient type and histological type, radiotherapy treatment characteristics, and tumor stage. RESULTS 610 patients underwent initial radiotherapy. 37% of cases had stage III squamous cell lung cancer and were treated with radical therapy. 81% of patients with non-small and small cell lung cancer were treated with concomitant chemo-radiotherapy and the administered total dose was ≥60 Gy and ≥45 Gy respectively. The most common regimen for patients treated with palliative intent (44.6%) was 30 Gy. The total irradiation rate was 19.6% with significant differences among provinces (range, 8.5-25.6%; p<0.001). These differences were significantly correlated with the geographical distribution of radiation oncologists (r=0.78; p=0.02). Our results were similar to other published data and previous study VARA-I. CONCLUSIONS Our results shows no differences according to the other published data and data gathered in the study VARA-I. There is still wide variability in the application of radiotherapy for lung cancer in our setting that significantly correlates with the geographical distribution of radiation oncologists.

Impacto del apoyo social y la morbilidad psíquica en la calidad de vida en pacientes tratados con antirretrovirales

The impact of the social support and the psychic morbidity on the quality of life of patients with antiretroviral therapy. The aim of this study is to analyse the existing relation between the psychic morbidity and social support and the quality of life. Besides this, the paper analyses the buffer rol that social support plays on the psychic morbidity in these patients. We studied 320 HIV+ patients in truatment with antiretrovirals, who attended the infectious disease services of four hospitals of the Autonomous Andalusian Community. Being associated a better quality of life to an absence of psychic morbidity and to the presence of social support, it is observed the relevant buffer role that the social support like shock absorber of the psychic morbidity in this one type of patients. These results show the importance that the psycho-social factors have during the course of chronic diseases.

Pigment production by Streptococcus agalactiae in quasi-defined media.

A quasi-defined medium that supports the growth of Streptococcus agalactiae as pigmented colonies has been developed. The medium contains starch, a peptic digest of albumin, amino acids, nucleosides, vitamins, and salts. The presence of free cysteine, which could be replaced with other sulphur-containing compounds and to a lesser degree by reducing agents, was required for pigment formation.

Patients' and physicians' preferences for type 2 diabetes mellitus treatments in Spain and Portugal: a discrete choice experiment.

OBJECTIVE To assess Spanish and Portuguese patients' and physicians' preferences regarding type 2 diabetes mellitus (T2DM) treatments and the monthly willingness to pay (WTP) to gain benefits or avoid side effects. METHODS An observational, multicenter, exploratory study focused on routine clinical practice in Spain and Portugal. Physicians were recruited from multiple hospitals and outpatient clinics, while patients were recruited from eleven centers operating in the public health care system in different autonomous communities in Spain and Portugal. Preferences were measured via a discrete choice experiment by rating multiple T2DM medication attributes. Data were analyzed using the conditional logit model. RESULTS Three-hundred and thirty (n=330) patients (49.7% female; mean age 62.4 [SD: 10.3] years, mean T2DM duration 13.9 [8.2] years, mean body mass index 32.5 [6.8] kg/m(2), 41.8% received oral + injected medication, 40.3% received oral, and 17.6% injected treatments) and 221 physicians from Spain and Portugal (62% female; mean age 41.9 [SD: 10.5] years, 33.5% endocrinologists, 66.5% primary-care doctors) participated. Patients valued avoiding a gain in bodyweight of 3 kg/6 months (WTP: €68.14 [95% confidence interval: 54.55-85.08]) the most, followed by avoiding one hypoglycemic event/month (WTP: €54.80 [23.29-82.26]). Physicians valued avoiding one hypoglycemia/week (WTP: €287.18 [95% confidence interval: 160.31-1,387.21]) the most, followed by avoiding a 3 kg/6 months gain in bodyweight and decreasing cardiovascular risk (WTP: €166.87 [88.63-843.09] and €154.30 [98.13-434.19], respectively). Physicians and patients were willing to pay €125.92 (73.30-622.75) and €24.28 (18.41-30.31), respectively, to avoid a 1% increase in glycated hemoglobin, and €143.30 (73.39-543.62) and €42.74 (23.89-61.77) to avoid nausea. CONCLUSION Both patients and physicians in Spain and Portugal are willing to pay for the health benefits associated with improved diabetes treatment, the most important being to avoid hypoglycemia and gaining weight. Decreased cardiovascular risk and weight reduction became the third most valued attributes for physicians and patients, respectively.
