Social involvement for community development in rural areas of Cuenca, Spain

Community development must be accompanied by a social involvement process which creates functional groups of citizens capable of taking responsibility for their own development. It is important that this process promotes the structuring of all population groups and provides the appropriate institutional and technical support. The present paper addresses these issues based on over 25 years of experience by the Association Instituto de Desarrollo Comunitario de Cuenca in revitalizing rural areas of the Spanish province of Cuenca. This paper analyses the social involvement process encouraged by this association, the relationships between public institutions and local associations, the role of these associations and the difficulties encountered in the rural areas. The long-term perspective of this experience provides some keys which can be used to successfully support the process of social involvement ―such as information on its characteristics and methodological tools―, establish local associations and create sustainable partnerships that foster the growth of leadership within the community development process

Dinamización Para El Desarrollo Comunitario En Territorios Rurales De Cuenca, España

El desarrollo comunitario ha de ir acompañado de un proceso de dinamización social que suscite grupos funcionales de ciudadanos capaces de ser responsables de su propio desarrollo. Es importante que este proceso fomente la estructuración de todos los grupos de población y cuente con un apoyo técnico e institucional apropiado. Para ello es necesario analizar algunos interrogantes en torno a las relaciones entre las instituciones públicas y las asociaciones locales, el papel de estas asociaciones y las dificultades encontradas en los territorios rurales. En este artículo se abordan dichas cuestiones desde la experiencia de más de 25 años de la Asociación Instituto de Desarrollo Comunitario de Cuenca en la dinamización de las zonas rurales de esta provincia española. Desde esta visión de largo plazo se proporcionan algunas claves para acompañar con éxito el proceso de dinamización ?características y herramientas metodológicas?, lograr la motivación de la población, el arraigamiento de las asociaciones locales, y la generación de partenariados sostenibles que fomenten el liderazgo de la comunidad en el proceso de desarrollo

Information as a Key Tool for Rural Development. 25 Years of Experience in Spain

The lack of useful information has become a major obstacle that hinders the participation of the members of the community in the development process because they can not accurately perceive how their individual and/or collective action can influence their environment, and because of the lack of elements that support the decision-making processes. This article addresses these issues from the work carried out by the Association Instituto de Desarrollo Comunitario de Cuenca (IDC Cuenca) in the rural areas of this province of Spain for 25 years. The results show how the application of methodologies for the transmission of information tailored to each group of recipients in some aspects, enhances the participation of individuals

Design of a case management model for people with chronic disease (Heart Failure and COPD). Phase I: modeling and identification of the main components of the intervention through their actors: patients and professionals (DELTA-ICE-PRO Study

Background Chronic diseases account for nearly 60% of deaths around the world. The extent of this silent epidemic has not met determined responses in governments, policies or professionals in order to transform old Health Care Systems, configured for acute diseases. There is a large list of research about alternative models for people with chronic conditions, many of them with an advanced practice nurse as a key provider, as case management. But some methodological concerns raise, above all, the design of the intervention (intensity, frequency, components, etc). Methods/Design Objectives: General: To develop the first and second phases (theorization and modeling) for designing a multifaceted case-management intervention in people with chronic conditions (COPD and heart failure) and their caregivers. Specific aims: 1) To identify key events in people living with chronic disease and their relation with the Health Care System, from their point of view. 2) To know the coping mechanisms developed by patients and their caregivers along the story with the disease. 3) To know the information processing and its utilization in their interactions with health care providers. 4) To detect potential unmet needs and the ways deployed by patients and their caregivers to resolve them. 5) To obtain a description from patients and caregivers, about their itineraries along the Health Care System, in terms of continuity, accessibility and comprehensiveness of care. 6) To build up a list of promising case-management interventions in patients with Heart Failure and COPD with this information in order to frame it into theoretical models for its reproducibility and conceptualization. 7) To undergo this list to expert judgment to assess its feasibility and pertinence in the Andalusian Health Care. Design: Qualitative research with two phases: For the first five objectives, a qualitative technique with biographic stories will be developed and, for the remaining objectives, an expert consensus through Delphi technique, on the possible interventions yielded from the first phase. The study will be developed in the provinces of Almería, Málaga and Granada in the Southern Spain, from patients included in the Andalusian Health Care Service database with the diagnosis of COPD or Heart Failure, with the collaboration of case manager nurses and general practitioners for the assessment of their suitability to inclusion criteria. Patients and caregivers will be interviewed in their homes or their Health Centers, with their family or their case manager nurse as mediator. Discussion First of a series of studies intended to design a case-management service for people with heart failure and COPD, in the Andalusian Health Care System, where case management has been implemented since 2002. Accordingly with the steps of a theoretical model for complex interventions, in this study, theorization and intervention modeling phases will be developed.This research was carried out with the support of one research grant, awarded by the Regional Health Ministry of Andalusia (Exp. 0222/2008

Identification of new sources of resistance to RHBV- rice hoja blanca virus

With the aim to find new sources of resistance to rice hoja blanca (white leaf) disease, transmitted by the insect Tagosodes orizicolus, 660 genotypes were evaluated under greenhouse and field conditions. Seven resistant genotypes were identified, and genomic studies were performed to demonstrate that the resistance in these sources is genetically different from that of Fedearroz 2000, which is currently the variety with the most resistance to hoja blanca. These new resistance sources constitute a resource that can be used to sustainably extend hoja blanca disease management throughout all of the rice-growing regions of tropical America. This is the first report of hoja blanca resistance in indica rice and different from that of Fedearroz 2000

Proteomic approach in the search of new cardiovascular biomarkers

Proteomic approach in the search of new cardiovascular biomarkers With the increasing incidence of cardiovascular diseases worldwide, specifically atherosclerosis and heart failure, the search for novel biomarkers remains a priority. As opposed to complex diagnostic techniques that may not be suitable to be applied to the wider population, biomarkers are useful for population screening. The search for novel biomarkers is based on knowledge of the molecular and cellular processes that take place in the development of a specific disease. Atherosclerosis and heart failure are characterized by a long period of silent disease progression, allowing early diagnosis and the potential of early therapeutic intervention. The use of the so-called proteomic techniques allows not only protein identification but partial characterization, which includes expression and also post-translational modification of these proteins. This allows for the discovery of previously unknown proteins involved in cardiovascular diseases, including some that may be suitable to be used as biomarkers. However, to approach this issue, we have to overcome difficulties such as tissue heterogeneity (vessel wall or myocardium) and the lack of fresh human samples. We discuss the proteomic study of human plaques, secreted proteins by pathologic and normal vessel wall, and left ventricular hypertrophy as potential sources of new biologic markers of cardiovascular disease

A standardized ophthalmologic examination and specific serological probes supported the diagnosis of severe bilateral ARNS in an immunocompetent child.Results: The reduced visual acuity (<20/400), the ocular fundus signs (perivasculitis, thrombosis and retinal edema) and the positive immunoglobulin M anti-Epstein Barr virus serology, lead us to the ARNS definitive diagnosis. Antiviral therapy (Acyclovir; Zovirax®), ciclopentolate dilating eye drops, and antiplatelet treatment (acetil salicylic acid; Aspirin®) were administered until recovering the final visual acuity (20/40).Conclusions: The ARNS is an ocular disease with poor prognosis, which in turns may display better course when determining the etiopathogenic virus and selecting the appropriate and precocious therapy.Keywords: retinal necrosis, Epstein-Barr virus, antiviral serology, antiviral therap

The pregnancy hormones human chorionic gonadotropin and progesterone induce human embryonic stem cell proliferation and differentiation into neuroectodermal rosettes

Introduction: The physiological signals that direct the division and differentiation of the zygote to form a blastocyst, and subsequent embryonic stem cell division and differentiation during early embryogenesis, are unknown. Although a number of growth factors, including the pregnancy-associated hormone human chorionic gonadotropin (hCG) are secreted by trophoblasts that lie adjacent to the embryoblast in the blastocyst, it is not known whether these growth factors directly signal human embryonic stem cells (hESCs). Methods: Here we used hESCs as a model of inner cell mass differentiation to examine the hormonal requirements for the formation of embryoid bodies (EB’s; akin to blastulation) and neuroectodermal rosettes (akin to neurulation). Results: We found that hCG promotes the division of hESCs and their differentiation into EB’s and neuroectodermal rosettes. Inhibition of luteinizing hormone/chorionic gonadotropin receptor (LHCGR) signaling suppresses hESC proliferation, an effect that is reversed by treatment with hCG. hCG treatment rapidly upregulates steroidogenic acute regulatory protein (StAR)-mediated cholesterol transport and the synthesis of progesterone (P4). hESCs express P4 receptor A, and treatment of hESC colonies with P4 induces neurulation, as demonstrated by the expression of nestin and the formation of columnar neuroectodermal cells that organize into neural tubelike rosettes. Suppression of P4 signaling by withdrawing P4 or treating with the P4-receptor antagonist RU-486 inhibits the differentiation of hESC colonies into EB’s and rosettes. Conclusions: Our findings indicate that hCG signaling via LHCGR on hESC promotes proliferation and differentiation during blastulation and neurulation. These findings suggest that trophoblastic hCG secretion and signaling to the adjacent embryoblast could be the commencement of trophic support by placental tissues in the growth and development of the human embryo

Acute febrile illness is associated with Rickettsia spp infection in dogs

BACKGROUND: Rickettsia conorii is transmitted by Rhipicephalus sanguineus ticks and causes Mediterranean Spotted Fever (MSF) in humans. Although dogs are considered the natural host of the vector, the clinical and epidemiological significance of R. conorii infection in dogs remains unclear. The aim of this prospective study was to investigate whether Rickettsia infection causes febrile illness in dogs living in areas endemic for human MSF. METHODS: Dogs from southern Italy with acute fever (n = 99) were compared with case–control dogs with normal body temperatures (n = 72). Serology and real-time PCR were performed for Rickettsia spp., Ehrlichia canis, Anaplasma phagocytophilum/A. platys and Leishmania infantum. Conventional PCR was performed for Babesia spp. and Hepatozoon spp. Acute and convalescent antibodies to R. conorii, E. canis and A. phagocytophilum were determined. RESULTS: The seroprevalence rates at first visit for R. conorii, E. canis, A. phagocytophilum and L. infantum were 44.8%, 48.5%, 37.8% and 17.6%, respectively. The seroconversion rates for R. conorii, E. canis and A. phagocytophilum were 20.7%, 14.3% and 8.8%, respectively. The molecular positive rates at first visit for Rickettsia spp., E. canis, A. phagocytophilum, A. platys, L. infantum, Babesia spp. and Hepatozoon spp. were 1.8%, 4.1%, 0%, 2.3%, 11.1%, 2.3% and 0.6%, respectively. Positive PCR for E. canis (7%), Rickettsia spp. (3%), Babesia spp. (4.0%) and Hepatozoon spp. (1.0%) were found only in febrile dogs. The DNA sequences obtained from Rickettsia and Babesia PCRs positive samples were 100% identical to the R. conorii and Babesia vogeli sequences in GenBank®, respectively. Febrile illness was statistically associated with acute and convalescent positive R. conorii antibodies, seroconversion to R. conorii, E. canis positive PCR, and positivity to any tick pathogen PCRs. Fourteen febrile dogs (31.8%) were diagnosed with Rickettsia spp. infection based on seroconversion and/or PCR while only six afebrile dogs (12.5%) seroconverted (P = 0.0248). The most common clinical findings of dogs with Rickettsia infection diagnosed by seroconversion and/or PCR were fever, myalgia, lameness, elevation of C-reactive protein, thrombocytopenia and hypoalbuminemia. CONCLUSIONS: This study demonstrates acute febrile illness associated with Rickettsia infection in dogs living in endemic areas of human MSF based on seroconversion alone or in combination with PCR
