Propuestas de clase social neoweberiana y neomarxista a partir de la Clasificación Nacional de Ocupaciones 2011

In Spain, the new National Classification of Occupations (Clasificación Nacional de Ocupaciones [CNO-2011]) is substantially different to the 1994 edition, and requires adaptation of occupational social classes for use in studies of health inequalities. This article presents two proposals to measure social class: the new classification of occupational social class (CSO-SEE12), based on the CNO-2011 and a neo-Weberian perspective, and a social class classification based on a neo-Marxist approach. The CSO-SEE12 is the result of a detailed review of the CNO-2011 codes. In contrast, the neo-Marxist classification is derived from variables related to capital and organizational and skill assets. The proposed CSO-SEE12 consists of seven classes that can be grouped into a smaller number of categories according to study needs. The neo-Marxist classification consists of 12 categories in which home owners are divided into three categories based on capital goods and employed persons are grouped into nine categories composed of organizational and skill assets. These proposals are complemented by a proposed classification of educational level that integrates the various curricula in Spain and provides correspondences with the International Standard Classification of Education.

CALHM1 P86L Polymorphism is Associated with Late-Onset Alzheimer's Disease in a Recessive Model

CALHM1 gene coding non-synonymous SNP P86L (rs2986017) was reported to increase the risk of Alzheimers disease (AD) in a recent study. We have investigated this genetic variant in 2470 individuals from Spain to conduct an independent replication study of the proposed SNP marker. By applying a recessive model, we observed weak evidence of an association between P86L mutation and late-onset AD (LOAD) susceptibility in our case-control study (OR =1.38 C.I. = [1.01-1.89]). Meta-analysis of available studies also supports a recessive model for CALHM1 P86L variant and provides evidence of between study heterogeneity. Importantly, we found that adjusted mean age at AD onset in P86L homozygous LOAD patients was significantly earlier that in the rest of patients (77.01 +/- 6.1 for P86L homozygous carriers versus 79.0 +/- 6.0 for the rest of patients, p=0.002). We concluded that the CALMH1 gene may contribute to AD risk in our study population. The observed genetic model (recessive) and the estimated magnitude of the effect both imply that virtually all studies performed to date were markedly underpowered to detect this effect and underscore the importance of follow up, replication, and meta-analyses of promising genetic signals.

ATP5H/KCTD2 locus is associated with Alzheimer's disease risk

To identify loci associated with Alzheimer disease, we conducted a three-stage analysis using existing genome-wide association studies (GWAS) and genotyping in a new sample. In Stage I, all suggestive single-nucleotide polymorphisms (at P<0.001) in a previously reported GWAS of seven independent studies (8082 Alzheimer’s disease (AD) cases; 12 040 controls) were selected, and in Stage II these were examined in an in silico analysis within the Cohorts for Heart and Aging Research in Genomic Epidemiology consortium GWAS (1367 cases and 12904 controls). Six novel signals reaching P<5 × 10−6 were genotyped in an independent Stage III sample (the Fundació ACE data set) of 2200 sporadic AD patients and 2301 controls. We identified a novel association with AD in the adenosine triphosphate (ATP) synthase, H+ transporting, mitochondrial F0 (ATP5H)/Potassium channel tetramerization domain-containing protein 2 (KCTD2) locus, which reached genome-wide significance in the combined discovery and genotyping sample (rs11870474, odds ratio (OR)=1.58, P=2.6 × 10−7 in discovery and OR=1.43, P=0.004 in Fundació ACE data set; combined OR=1.53, P=4.7 × 10−9). This ATP5H/KCTD2 locus has an important function in mitochondrial energy production and neuronal hyperpolarization during cellular stress conditions, such as hypoxia or glucose deprivation.

Does palliative care education matter to medical students? The experience of attending an undergraduate course in palliative care

Background Palliative care (PC) education has become a priority in many European countries where PC is quickly developing. There remains, however, a lack of information on acceptability and medical students’ experiences in PC education. This kind of information is important because it could encourage universities to adapt their curricula appropriately to the demographic and societal necessity. Objective To explore medical students’ reactions to an optional PC course using their reflective written comments. Methods 316 medical students at the University of Navarra, over a period of 4 years, wrote evaluative comments regarding their experience and what they perceived as the courses contribution to their education. With these comments, a qualitative thematic analysis was carried out. Results With a response ratio of 90%, five main themes were identified: (1) The course helped medical students to become and act as doctors, (2) The benefits of having a holistic view of the patient and taking the family into account, (3) PC opens up a new a field of knowledge, (4) The course makes students think and reflect on their personal development and encourages them to deepen humanistic aspects of their practice, (5) The practical aspect is essential in PC learning. In addition, significantly, students used vigorous and positive expressions when writing about their experiences. Discussion The subject of PC turns out to be very important to students, who almost unanimously evaluated their experience positively and highlighted the benefits of attending a PC course. Students especially reported being surprised by the humane and holistic features of the course, and they found that what they learned in the course is applicable to all patients and prepares them to work better as doctors. Participants recommend the course for all undergraduate students as a core component of the curricula.

Coverage and development of specialist palliative care services across the World Health Organization European Region (2005–2012): Results from a European Association for Palliative Care Task Force survey of 53 Countries

Background: The evolution of the provision of palliative care specialised services is important for planning and evaluation. Aim: To examine the development between 2005 and 2012 of three specialised palliative care services across the World Health Organization European Region – home care teams, hospital support teams and inpatient palliative care services. Design and setting: Data were extracted and analysed from two editions of the European Association for Palliative Care Atlas of Palliative Care in Europe. Significant development of each type of services was demonstrated by adjusted residual analysis, ratio of services per population and 2012 coverage (relationship between provision of available services and demand services estimated to meet the palliative care needs of a population). For the measurement of palliative care coverage, we used European Association for Palliative Care White Paper recommendations: one home care team per 100,000 inhabitants, one hospital support team per 200,000 inhabitants and one inpatient palliative care service per 200,000 inhabitants. To estimate evolution at the supranational level, mean comparison between years and European sub-regions is presented. Results: Of 53 countries, 46 (87%) provided data. Europe has developed significant home care team, inpatient palliative care service and hospital support team in 2005–2012. The improvement was statistically significant for Western European countries, but not for Central and Eastern countries. Significant development in at least a type of services was in 21 of 46 (46%) countries. The estimations of 2012 coverage for inpatient palliative care service, home care team and hospital support team are 62%, 52% and 31% for Western European and 20%, 14% and 3% for Central and Eastern, respectively. Conclusion: Although there has been a positive development in overall palliative care coverage in Europe between 2005 and 2012, the services available in most countries are still insufficient to meet the palliative care needs of the population.

‘Dignity therapy’, a promising intervention in palliative care: A comprehensive systematic literature review

Background: Dignity therapy is psychotherapy to relieve psychological and existential distress in patients at the end of life. Little is known about its effect. Aim: To analyse the outcomes of dignity therapy in patients with advanced life-threatening diseases. Design: Systematic review was conducted. Three authors extracted data of the articles and evaluated quality using Critical Appraisal Skills Programme. Data were synthesized, considering study objectives. Data sources: PubMed, CINAHL, Cochrane Library and PsycINFO. The years searched were 2002 (year of dignity therapy development) to January 2016. ‘Dignity therapy’ was used as search term. Studies with patients with advanced life-threatening diseases were included. Results: Of 121 studies, 28 were included. Quality of studies is high. Results were grouped into effectiveness, satisfaction, suitability and feasibility, and adaptability to different diseases and cultures. Two of five randomized control trials applied dignity therapy to patients with high levels of baseline psychological distress. One showed statistically significant decrease on patients’ anxiety and depression scores over time. The other showed statistical decrease on anxiety scores pre–post dignity therapy, not on depression. Nonrandomized studies suggested statistically significant improvements in existential and psychosocial measurements. Patients, relatives and professionals perceived it improved end-of-life experience. Conclusion: Evidence suggests that dignity therapy is beneficial. One randomized controlled trial with patients with high levels of psychological distress shows DT efficacy in anxiety and depression scores. Other design studies report beneficial outcomes in terms of end-of-life experience. Further research should understand how dignity therapy functions to establish a means for measuring its impact and assessing whether high level of distress patients can benefit most from this therapy.

Spanish Version of the Patient Dignity Inventory: Translation and Validation in Patients With Advanced Cancer

CONTEXT The Patient Dignity Inventory (PDI) is an instrument to measure sources of distress related to dignity at the end of life. OBJECTIVES To obtain a Spanish version of the PDI and measure psychometric aspects in patients with advanced cancer. METHODS A back-translation method was used to obtain the Spanish version. Inpatients and outpatients with advanced cancer were included. Patients completed the Spanish versions of the PDI (PDI-s), Edmonton Symptom Assessment System (ESAS), Hospital Anxiety and Depression Scale (HADS), and Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-Sp-12) instruments. The psychometric properties evaluated were internal consistency; concurrent validity between PDI-s/ESAS, PDI-s/HADS, and PDI-s/FACIT-Sp-12; discriminant validity, test-retest reliability, and factor analysis. The usefulness of the instrument also was tested. RESULTS A Spanish version of the PDI was obtained. One hundred twenty-four patients completed the study. Cronbachs alpha coefficient for the PDI-s was 0.89. The PDI-s significantly correlated with the ESAS (rs = 0.669; P < 0.001), HADS (rs = 0.788; P < 0.001), and FACIT-Sp-12 (rs = -0.442; P = 0.008). The instrument distinguished outpatients from inpatients and between patients with differing Karnofsky Performance Status scores (rs = -0.328; P < 0.001). The test-retest method indicated excellent reproducibility (intraclass correlation coefficient = 0.931). Factor analysis showed three factors accounting for 79.4% of the variance. Factors were labeled psychological and existential distress, physical symptoms and dependency, and social support. Patients had no difficulties in understanding or completing the questionnaire (mean time to complete: 7.2 minutes). CONCLUSION The Spanish version of the PDI showed adequate psychometric properties when tested with advanced cancer patients. This research provides a three-factor alternative in Spanish to the PDI.

A Colorectal Cancer Susceptibility New Variant at 4q26 in the Spanish Population Identified by Genome-Wide Association Analysis

Background Non-hereditary colorectal cancer (CRC) is a complex disorder resulting from the combination of genetic and non-genetic factors. Genome–wide association studies (GWAS) are useful for identifying such genetic susceptibility factors. However, the single loci so far associated with CRC only represent a fraction of the genetic risk for CRC development in the general population. Therefore, many other genetic risk variants alone and in combination must still remain to be discovered. The aim of this work was to search for genetic risk factors for CRC, by performing single-locus and two-locus GWAS in the Spanish population. Results A total of 801 controls and 500 CRC cases were included in the discovery GWAS dataset. 77 single nucleotide polymorphisms (SNP)s from single-locus and 243 SNPs from two-locus association analyses were selected for replication in 423 additional CRC cases and 1382 controls. In the meta-analysis, one SNP, rs3987 at 4q26, reached GWAS significant p-value (p = 4.02×10−8), and one SNP pair, rs1100508 CG and rs8111948 AA, showed a trend for two-locus association (p = 4.35×10−11). Additionally, our GWAS confirmed the previously reported association with CRC of five SNPs located at 3q36.2 (rs10936599), 8q24 (rs10505477), 8q24.21(rs6983267), 11q13.4 (rs3824999) and 14q22.2 (rs4444235). Conclusions Our GWAS for CRC patients from Spain confirmed some previously reported associations for CRC and yielded a novel candidate risk SNP, located at 4q26. Epistasis analyses also yielded several novel candidate susceptibility pairs that need to be validated in independent analyses.

Policy on palliative care in the WHO European region: an overview of progress since the Council of Europe's (2003) recommendation 24.

BACKGROUND With the goal of achieving greater unity and coherence, the Council of Europe developed a national palliative care (PC) policy framework-Recommendation (2003) 24. Although directed at member states, the policy spread to the wider World Health Organisation (WHO) European Region. This article aims to present the current situation relating to national PC health policies in European countries. METHODS A cross-sectional survey was conducted in 53 European countries of the WHO European Region. Relevant data reported (i) the existence of official documents concerning the provision of PC; (ii) the role of health departments and policymakers in the evaluation of PC provision and (iii) the availability of financial resources for PC provision. RESULTS In total, 46/53 (87%) EU and non-EU countries responded. PC legislation is established in 20 (71%) EU and nine (50%) non-EU countries. A total of 12 (43%) EU countries possess a PC plan or strategy in comparison with six (33%) non-EU countries. Individuals from Departments of Health and designated policymakers have established collaborative PC efforts. Quality systems have been initiated in 15 (54%) EU and four (22%) non-EU countries. Significant differences were not found in the reporting of payments for PC services between European regions. CONCLUSION An improvement in national PC policy in both EU and non-EU countries was observed. Future priorities include potential initiatives to improve relationships with policymakers, establish quality control programmes and ensure financial support for PC.

Integrated palliative care in the Spanish context: a systematic review of the literature.

BackgroundIntegrated palliative care (IPC) involves bringing together administrative, organisational, clinical and service aspects in order to achieve continuity of care between all actors involved in the care network of patients receiving palliative care (PC) services. The purpose of this study is to identify literature on IPC in the Spanish context, either in cancer or other advanced chronic diseases.MethodsSystematic review of the literature about IPC published in Spain between 1995 and 2013. Sources searched included PubMed, Cochrane Library, Cinahl, the national palliative care Journal (Medicina Paliativa), and Google. Evidence on IPC in care models, pathways, guidelines and other relevant documents were searched. Additionally, data were included from expert sources. Elements of IPC were considered based on the definition of IPC and the Emmanuel´s IPC tool. The main inclusion criterion was a comprehensive description of PC integration.ResultsOut of a total of 2,416 titles screened, 49 were included. We found two models describing IPC interventions achieving continuity and appropriateness of care as a result, 12 guidelines or pathways (most of them with a general approach including cancer and non-cancer and showing a theoretical IPC inclusion as measured by Emmanuel’s tool) and 35 other significant documents as for their context relevance (17 health strategy documents, 14 analytical studies and 4 descriptive documents). These last documents comprised respectively: regional and national plans with an IPC inclusion evidence, studies focused on IPC into primary care and resource utilisation; and descriptions of fruitful collaboration programmes between PC teams and oncology departments.ConclusionsThe results show that explications of IPC in the Spanish literature exist, but that there is insufficient evidence of its impact in clinical practice. This review may be of interest for Spanish-speaking countries and for others seeking to know the status of IPC in the literature in their home nations.
