Neither dashboard nor 'mashup' indices: an empirical wealth approach as a pathway to a comprehensive measure of development

The article is composed of two sections. The first one is a critical review of the three main alternative indices to GDP which were proposed in the last decades – the Human Development Index (HDI), the Genuine Progress Indicator (GPI), and the Happy Planet Index (HPI) – which is made on the basis of conceptual foundations, rather than looking at issues of statistical consistency or mathematical refinement as most of the literature does. The pars construens aims to propose an alternative measure, the composite wealth index, consistent with an approach to development based on the notion of composite wealth, which is in turn derived from an empirical common sense criterion. Arguably, this approach is suitable to be conveyed into an easily understandable and coherent indicator, and thus appropriate to track development in its various dimensions: simple in its formulation, the wealth approach can incorporate social and ecological goals without significant alterations in conceptual foundations, while reducing to a minimum arbitrary weighting.

European Home and Leisure Accident Surveillance System report for Ireland 2001

EHLASS provides a harmonised approach throughout the EU to facilitate the analyses of intercountry differences in modes and distributions of home and leisure accidents. EHLASS contributes to the formulation of EU policies and initiatives on accidents and product safety. EHLASS is the only source of detailed information on home and leisure accidents in Ireland. Some general information is available through the Hospital In-Patient Enquiry (HIPE) system but this concentrates on medical diagnoses rather than on specific causes of accidents.This report is the eleventh national EHLASS report for Ireland.

Health Statistics 2002

The four key principles guiding the development of the Health Strategy (2001): Quality and Fairness: A Health System for You are equity, people-centredness, quality and accountability. High quality statistical data are fundamental to the delivery of each of these. Relevant, accurate and accessible information should inform all health decisions. This includes information for the public as well as data required to enable evidence-based service delivery and evaluation, policy formulation and the measurement of health gain.This compendium of health statistics brings together data from a wide variety of sources on demography, health status and the delivery of health services. It provides a broad overview of health in Ireland as well as serving as a resource and reference for those interested in particular aspects of health and the health services. Download document here

Genetic markers between Biomphalaria glabrata snails susceptible and resistant to Schistosoma mansoni infection

The analysis of the genetic variability related to susceptibility to Schistosoma mansoni infection in the vector of the genus Biomphalaria is important in terms of a better understanding of the epidemiology of schistosomiasis itself, the possible pathological implications of this interaction in vertebrate hosts, and the formulation of new strategies and approaches for disease control. In the present study, the genetic variability of B. glabrata strains found to be resistant or susceptible to S. mansoni infection was investigated using DNA amplification by random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR). The amplification products were analyzed on 8% polyacrylamide gel and stained with silver. We selected 10 primers, since they have previously been useful to detect polymorphism among B. glabrata and/or B. tenagophila. The results showed polymorphisms with 5 primers. Polymorphic bands observed only in the susceptible strain. The RAPD-PCR methodology represents an adequate approach for the analysis of genetic polymorphisms. The understanding of the genetic polymorphisms associated to resistance may contribute to the future identification of genomic sequences related to the resistance/susceptibility of Biomphalaria to the larval forms of S. mansoni and to the development of new strategies for the control of schistosomiasis.

Oviposition response of the mosquito, Culex quinquefasciatus to the secondary metabolite(s) of the fungus, Trichoderma viride

Secondary metabolites produced by Trichoderma viride, a deuteromycetes fungus, under submerged culture condition were formulated and evaluated for oviposition attractancy against gravid females of Culex quinquefasciatus mosquito. At a concentration of 10 µg ml-1 the formulation showed remarkable attractancy with an oviposition active index (OAI) of +0.52. When the oviposition attractancy of the formulation was compared with a known oviposition attractant, p-cresol, both at 10 µg ml-1, the former was found to be more attractive to result in 70% egg laying than the later with 30% egg laying. Thin layer chromatography fractions of the secondary metabolites showed that a fraction with Rf value of 0.88 was highly active as oviposition attractant with an OAI of +0.65. Further work on identification of the active principle(s) of the microbial formulation might lead to an oviposition attractant useful in mosquito vector management.

Distribution of free and liposomal doxorubicin after isolated lung perfusion in a sarcoma model

Rapport de synthèse : Introduction : La perfusion isolée du poumon à l'aide de Doxorubicine libre et une nouvelle forme de Doxorubicine liposomale pégylée (Liporubicine) est comparé en terme de pénétration et accumulation de Doxorubicine dans le tissu tumoral et pulmonaire dans un modèle de rats porteurs de tumeur sarcomateuse au niveau du poumon gauche. Matériel et méthode : Une tumeur sarcomateuse unique a été générée dans le poumon gauche de 39 Fischer rats, suivi 10 jours plus tard, par une perfusion isolée du poumon gauche (n =36) avec Doxorubicine libre (n=18) et Liporubicine (n=18) à une dose de 100 µg (n=9) et 400 µg (n=9) pour chaque formulation de Doxorubicine. Dans chaque poumon perfusé, la concentration de l'agent cytostatique et sa distribution ont été investiguées dans la tumeur et trois parties du poumon normal par HLPC (n=6) et par microscopie de florescence (n=3). Des analyses histologiques et inmunohistochimiques (facteur von Willebrand) ont été effectuées sur trois animaux non traités. Résultats : Les tumeurs sarcomateuses dans les animaux de contrôle démontraient une bonne vascularisation avec de fines branches capillaires qui étaient présentes partout dans les tumeurs. La perfusion isolée du poumon démontrait une distribution de l'agent cytostatique d'une manière hétérogène dans le poumon perfusé et une concentration de Doxorubicine inférieure dans les tumeurs par rapport au tissu pulmonaire sein pour les deux formulations de Doxorubicine et les deux doses appliquées. La perfusion isolée du poumon avec Doxorubicine libre démontrait une concentration significativement plus élevée que Liporubicine dans la tumeur et le parenchyme pulmonaire pour les deux doses appliquées (p < 0,01). Néanmoins, le coefficient de concentration tumorale et pulmonaire était plus bas pour Doxorubicine libre que pour Liporubicine pour une dose de 100 µg (0.27 ± 0.1 vs 0.53 ± 0.5, p=0.23) tandis qu'il était similaire pour les deux formulations de Doxorubicine à une dose de 400 µg (0.67 ± 0.2 vs 0.54 ± 0.2, p=0.34). Les deux formulations de Doxorubicine émergeaient un signal de fluorescence provenant de tous les compartiments du parenchyme pulmonaire mais seulement un signal sporadique et faible émergeant des tumeurs, provenant de la périphérie de la tumeur et des vaisseaux situés à l'intérieur de la tumeur, pour les deux doses appliquées. Conclusion : La perfusion isolée du poumon démontrait une distribution hétérogène de la Doxorubicine et sa forme liposomale dans le poumon perfusé et une accumulation plus faible dans la tumeur que dans le tissu parenchymateux adjacent pour les deux formulations de Doxorubicine et les deux doses appliquées.

Primary spinal epidural lymphoma: patients' profile, outcome, and prognostic factors: a multicenter Rare Cancer Network study

RESUME Objectif : Les lymphomes épiduraux primaires représentent moins de 10% des tumeurs épidurales et de 0,1 à 3,3% de tous les lymphomes. Le but de cette étude a été d'évaluer le profil clinique de cette maladie rare, son traitement, ses résultats ainsi que ses facteurs de pronostic. Matériel et méthode : Entre 1982 et 2002, 52 patients présentant un lymphome épidural primaire ont été traités dans neuf institutions membres du Rare Cancer Network. Les critères d'inclusion comprenaient : une biopsie confirmant le lymphome non-hodgkinien, un stade IE et IIE selon la classification de Ann Arbor, un traitement à visée curative de radiothérapie combinée ou non à une chimiothérapie et un suivi d'au moins six mois. Selon la Working Formulation, 12 patients (23%) présentaient un lymphome de bas grade, 28 (54%) un grade intermédiaire et 12 (23%) un haut grade. Les hommes étaient atteints 1.9 fois plus fréquemment que les femmes. L'âge moyen était de 61 ans (intervalle : 21 à 96). Le bilan incluait un Ct-scan spinal (98%), une IRM (52%), un CT-scan thoraco-abdominal (77%) et une aspiration ou biopsie de moelle osseuse (96%). Les symptômes les plus fréquents comprenaient des douleurs dorsales (79% des patients), une faiblesse musculaire (92%) et des déficits sensoriels (71 %). Quarante-huit patients ont subi une laminectomie de décompression avec résection partielle ou complète (42% et 13% des cas respectivement), tous ont reçu une radiothérapie seule (20 patients) ou en combinaison avec une chimiothérapie (32 patients). La dose médiane totale était de 36 Gy (intervalle 6-50 Gy) avec une moyenne de 20 Gy par fraction (intervalle : 1-25). Le suivi moyen était de 71 mois (intervalle : 22-165 mois). Résultats : Suite au traitement, une progression locale a été observée chez 6 patients après un temps de latence moyen de 6 mois. Le taux de rechute systémique a été de 42% (22 patients) le plus souvent dans les ganglions lymphatiques (n=9) après un intervalle de temps moyen de 20 mois. Lors du dernier contrôle, 28 patients étaient vivants et 24 patients étaient décédés. Le taux de survie à 5 ans, le taux de survie sans maladie et le contrôle local étaient de 69%, 57% et 88% respectivement. En analyse univariée, les facteurs pronostics favorables statistiquement significatifs concernant la survie sans maladie étaient un âge inférieur à 63 ans, ainsi qu'une réponse neurologique complète. Pour la survie à 5 ans, les facteurs favorables étaient un âge inférieur à 63 ans. En analyse multivariée, les facteurs pronostics favorables pour la survie globale à 5 ans étaient une réponse neurologique complète, un traitement combiné, un volume de radiothérapie plus que focal, une dose totale de radiothérapie supérieure à 36 Gy et une résection partielle ou complète de la tumeur. En ce qui concerne la survie sans maladie, les facteurs pronostics favorables étáient un âge inférieur à 63 ans et un traitement combiné. Conclusion : Ce qui ressort de cette analyse est que le bilan diagnostic devrait inclure une IRM ou un CT-scan, un échantillon de tissu pour poser le diagnostic pathologique définitif de la lésion, une histoire médicale et un examen physique complet, une chimie sanguine, un CTscan thoraco-abdominal et une biopsie de la moelle osseuse, un PET-scan devrait également faire partie du bilan. Le traitement devrait consister, dans la phase aiguë, en une chirurgie de décompression avec ou sans résection, suivie d'une radiothérapie d'au moins 36Gy en 2 Gy par fraction et d'une chimiothérapie. Tous les patients présentant un lymphome de haut grade ou de grade intermédiaire devraient pouvoir bénéficier d'un traitement combiné.

Local moderate magnetically induced hyperthermia using an implant formed in situ in a mouse tumor model.

Purpose: We investigate a new heat delivery technique for the local treatment of solid tumors. The technique involves injecting a formulation that solidifies to form an implant in situ. This implant entraps superparamagnetic iron oxide nanoparticles (SPIONs) embedded in silica microbeads for magnetically induced moderate hyperthermia. Particle entrapment prevents phagocytosis and distant migration of SPIONs. The implant can be repeatedly heated by magnetic induction. Methods: We evaluated heating and treatment efficacies by means of thermometry and survival studies in nude mice carrying subcutaneous human colocarcinomas. At day 1, we injected the formulation into the tumor. At day 2, a single 20-min hyperthermia treatment was delivered by 141-kHz magnetic induction using field strengths of 9 to 12 mT under thermometry. Results: SPIONs embedded in silica microbeads were effectively confined within the implant at the injection site. Heat-induced necro-apoptosis was assessed by histology on day 3. On average, 12 mT resulted in tumor temperature of 47.8 degrees C, and over 70% tumor necrosis that correlated to the heat dose (AUC = 282 degrees C.min). In contrast, a 9-mT field strength induced tumoral temperature of 40 degrees C (AUC = 131 degrees C.min) without morphologically identifiable necrosis. Survival after treatment with 10.5 or 12 mT fields was significantly improved compared to non-implanted and implanted controls. Median survival times were 27 and 37 days versus 12 and 21 days respectively. Conclusion: Five of eleven mice (45%) of the 12 mT group survived one year without any tumor recurrence, holding promise for tumor therapy using magnetically induced moderate hyperthermia through injectable implants.

A viscous bioerodible poly(ortho ester) as a new biomaterial for intraocular application.

The biocompatibility of a viscous, hydrophobic, bioerodible poly(ortho ester) (POE) intended for intraocular application was investigated. POE was evaluated as a blank carrier and as containing modulators of degradation. Each formulation was injected intracamerally and intravitreally in rabbit eyes, and clinical and histological examinations were performed postoperatively for 2 weeks. In the case of intracameral injections, polymer biocompatibility appeared to depend on the amount injected in the anterior chamber. When 50 microL was administered, the polymer degraded within 2 weeks, and clinical observations showed good biocompatibility of POE with no toxicity to the ocular tissues or increase in intraocular pressure. The injection of a larger volume, 100 microL, of POE, appeared inappropriate because of direct contact of polymeric material with the corneal endothelium, and triggered reversible edema and inflammation in the anterior chamber of the eye that regressed after a few days. After intravitreal administration, POE was well tolerated and no inflammatory reaction developed during the observation period. The polymer degraded slowly, appearing as a round whitish bubble in the vitreous cavity. The presence of modulators of degradation both improved POE biocompatibility and prolonged polymer lifetime in the eye. POE appears to be a promising biomaterial for clinical intraocular application.

Activity of oil-formulated Beauveria bassiana against Triatoma sordida in peridomestic areas in central Brazil

Field tests were carried out during the rainy season of 2001/2002 in São Luís de Montes Belos, Goiás, Brazil, to evaluate the potential of the entomopathogenic fungus, Beauveria bassiana, against peridomestic Triatoma sordida. An oil-water formulation of the isolate CG 14 (Embrapa) was applied in triatomine infested hen houses of four farms at a final concentration of 10(6) conidia/cm². Numbers of T. sordida decreased over the next 25 days, after application of the fungus, and B. bassiana developed on dead insects in one hen house. A high number of B. bassiana colonies was detected in substrates collected in treated hen houses 24 h after application of CG 14. In the following three months the presenceof B. bassiana declined to values found before treatment.

COMMIT: Convex Optimization Modeling for Microstructure Informed Tractography.

Tractography is a class of algorithms aiming at in vivo mapping the major neuronal pathways in the white matter from diffusion magnetic resonance imaging (MRI) data. These techniques offer a powerful tool to noninvasively investigate at the macroscopic scale the architecture of the neuronal connections of the brain. However, unfortunately, the reconstructions recovered with existing tractography algorithms are not really quantitative even though diffusion MRI is a quantitative modality by nature. As a matter of fact, several techniques have been proposed in recent years to estimate, at the voxel level, intrinsic microstructural features of the tissue, such as axonal density and diameter, by using multicompartment models. In this paper, we present a novel framework to reestablish the link between tractography and tissue microstructure. Starting from an input set of candidate fiber-tracts, which are estimated from the data using standard fiber-tracking techniques, we model the diffusion MRI signal in each voxel of the image as a linear combination of the restricted and hindered contributions generated in every location of the brain by these candidate tracts. Then, we seek for the global weight of each of them, i.e., the effective contribution or volume, such that they globally fit the measured signal at best. We demonstrate that these weights can be easily recovered by solving a global convex optimization problem and using efficient algorithms. The effectiveness of our approach has been evaluated both on a realistic phantom with known ground-truth and in vivo brain data. Results clearly demonstrate the benefits of the proposed formulation, opening new perspectives for a more quantitative and biologically plausible assessment of the structural connectivity of the brain.

Immune response mechanisms and protection against "Plasmodium falciparum" and "Plasmodium berghei"

Malaria is one of the most important tropical and infectious diseases causing many deaths and enormous social and economic consequences, particularly in the developing countries. Despite of widely use of anti-malaria drugs and insecticide, the development of successful vaccines constitutes one of the main strategies to control malaria transmission. Several proteins expressed from blood stage such as merozoite surface proteins (MSP] or liver stage as circumsporozoite protein (CSP) are shown to be the targets of immune responses in humans and in animals. Thus, several studies have illustrated that natural infection and laboratory immunizations of humans and animals with Plasmodium sporozoite (SPZ) and its derivate-proteins (peptides) can elicit protection and control of parasite infection. However, a clear understanding of immune response against defined Plasmodium proteins should be the prerequisite conditions before any development of appropriate vaccines. In this order, our study focused on the immune responses to MSP2 (dimorphic and C-terminal fragments) in human and mice; and the mechanisms by which mouse infected hepatocytes present Plasmodium antigens to CD8+ T-cells to induce protective immunity in mice.¦The first part of this work shows that infected hepatocytes can present Plasmodium antigens to PbCSP-specific CD8+ T-cells and induce a protective immunity in mice. Here, this was addressed in vivo and showed that the infected hepatocytes were able of stimulating of primed-and naive-CD8+ T-cell clones and induced fully protective immunity against SPZ challenge. The role of infected hepatocytes in antigen presentation was illustrated here by their graft into immuno-deficient mice and depletion of cosspresenting dentritic cells (DCs) that are known to have key role in the activation of CD8+ T-cells during the liver cycle stage of Plasmodium.¦The second part of this project concerned the fine specificity of Ab responses regarding D and C regions of the two allelic families of MSP2 (3D7 and FC27). Covering of the two regions by overlapping-20 mers led to delineate the epitopes in the different endemic areas and different age groups of donors. The major epitopes characterizing D or C regions were conserved in different endemic areas (P12/P13 and P15/P16 for the 3D7-D, P23/24 and P25/26 for the FC27-D; P29/P30 for the C region). This offers thus, the possibility of a multi-epitope vaccine design including the major epitopes from the two domains of the two allelic MSP2 families. On the other, the 20 mers, particularly some major epitopes of the 3D7-Dregion (P12, P13 and P16) belonged to the epitopes that presented a high probability to be associated with protection in the children group [1 to 5 year-old). In addition, D and C LSP purified Abs (pAbs) recognized merozoite derived polypeptides and native proteins. A crossreactivity activity of homologous pAbs against the heterologous was also illustrated between the two allelic MSP2 parasites. Finally, the functional analysis of D regions pAbs showed an inhibition of Plasmodium falciparum growth suggesting the functional biological activity of the D region pAbs in the control of malaria.¦The last part of this project aimed the evaluation of the immunogenicity of the D and C region LSPs of the two allelic MSP2 families in the presence of adjuvants for the possible use in clinical trial study in humans. The MSP2 LSP mixture showed that D and C were immunogenic and defined limited epitopes (whose intensity of immune responses) depending on the adjuvants and mouse strain for the D regions. The major epitopes characterizing the C region were usually conserved in different strains of mouse and adjuvants used. Furthermore, the single region (either with D or C) immunization of mice confirmed the immunogenicity and the presence of their limited epitopes. We concluded that the possibility to finely delineate in animals the immune responses to antigens might help to select optimal antigen/adjuvant combinations to be tested later in clinical trials. Thus, formulation of glucopyranosyl-lipid A stable emulsion, GLA-SE (toll like receptor (TLR) 4 agonist) and its different combination (CpG: TLR9 agonist and GDQ: LR7 agonist) with MSP2 LSP was better than with alum, montanide ISA 720 (Mt) and virosome. Immunization of mice with allelic LSP did not show a crossreactivity between the two allelic MSP2 parasites unlike as humans, suggesting that the crossreactivity could be acquired during natural infection of the population who are usually exposed to both allelic parasite forms (3D7 and FC27).¦Nevertheless, similar epitope of D (P12, P13 and P25) and C (P29) regions have been found both in mice and human. This offers an opportunity to compare their epitopes in naïve immunized donors with LSPs and naturally infected populations in the endemic areas.

Benznidazole vs benznidazole in multilamellar liposomes: how different they interact with blood components?

In spite of its widespread use, benznidazole's (BNZ) toxicity and low efficacy remains as major drawbacks that impair successful treatments against Chagas disease. Previously, attempting to increase the selectivity and reduce its toxicity on infected tissues, multilamellar liposomes (MLV) composed of hydrogenated soybean phosphatidylcholine (HSPC): distearoyl-phosphatidylglycerol (DSPG): cholesterol (CHOL) 2:1:2 mol:mol loaded with BNZ (MLV-BNZ) were designed. In this work we compared different properties of MLV-BNZ with those of BNZ. Opposite to other hydrophobic drugs, the results indicated that slight changes of BNZ×s association degree to proteins and lipoproteins should not modify the percentage of unbound drug available to exert pharmacological action. On the other hand, when loaded in MLV, BNZ reduced its association to plasma proteins in 45% and became refractory to the sinking effect of blood, dropping 4.5 folds. Additionally, when loaded in MLV, BNZ had higher volume distribution (160 ± 20 vs 102 ± 15 ml/kg) and total clearance (35.23 ± 2.3 vs 21.9 ± 1.4 ml/h.kg), and lower concentration-time curve (7.23 ± 0.2 vs 9.16 ± 0.5 µg.h/ml) than BNZ. Hence, these studies showed that for MLV-BNZ, the amount of BNZ can be substantially increased, from 25 to 70%, being this formulation more rapidly cleared from circulation than free drug; also due to the lower interaction with blood components, lower side effects can be expected.

Public Policy and Ageing in Northern Ireland: Identifying Levers for Change

Public Policy and Ageing in Northern Ireland: Identifying Levers for Change Judith Cross, Policy Officer with the Centre for Ageing Research Development in Ireland (CARDI)��������Introduction Identifying a broad range of key public policy initiatives as they relate to age can facilitate discussion and create new knowledge within and across government to maximise the opportunities afforded by an ageing population. This article looks at how examining the current public policy frameworks in Northern Ireland can present opportunities for those working in this field for the benefit of older people. Good policy formulation needs to be evidence-based, flexible, innovative and look beyond institutional boundaries. Bringing together architects and occupational therapists, for example, has the potential to create better and more effective ways relevant to health, housing, social services and government departments. Traditional assumptions of social policy towards older people have tended to be medically focused with an emphasis on care and dependency. This in turn has consequences for the design and delivery of services for older people. It is important that these assumptions are challenged as changes in thinking and attitudes can lead to a redefinition of ageing, resulting in policies and practices that benefit older people now and in the future. Older people, their voices and experiences, need to be central to these developments. The Centre for Ageing Research and Development in Ireland The Centre for Ageing Research and Development in Ireland (CARDI) (1) is a not for profit organisation developed by leaders from the ageing field across Ireland (North and South) including age sector focused researchers and academics, statutory and voluntary, and is co-chaired by Professor Robert Stout and Professor Davis Coakley. CARDI has been established to provide a mechanism for greater collaboration among age researchers, for wider dissemination of ageing research information and to advance a research agenda relevant to the needs of older people in Ireland, North and South. Operating at a strategic level and in an advisory capacity, CARDI�۪s work focuses on promoting research co-operation across sectors and disciplines and concentrates on influencing the strategic direction of research into older people and ageing in Ireland. It has been strategically positioned around the following four areas: Identifying and establishing ageing research priorities relevant to policy and practice in Ireland, North and South;Promoting greater collaboration and co-operation on ageing research in order to build an ageing research community in Ireland, North and South;Stimulating research in priority areas that can inform policy and practice relating to ageing and older people in Ireland, North and South;Communicating strategic research issues on ageing to raise the profile of ageing research in Ireland, North and South, and its role in informing policy and practice. Context of Ageing in Ireland Ireland �۪s population is ageing. One million people aged 60 and over now live on the island of Ireland. By 2031, it is expected that Northern Ireland�۪s percentage of older people will increase to 28% and the Republic of Ireland�۪s to 23%. The largest increase will be in the older old; the number aged 80+ is expected to triple by the same date. However while life expectancy has increased, it is not clear that life without disability and ill health has increased to the same extent. A growing number of older people may face the combined effects of a decline in physical and mental function, isolation and poverty. Policymakers, service providers and older people alike recognise the need to create a high quality of life for our ageing population. This challenge can be meet by addressing the problems relating to healthy ageing, reducing inequalities in later life and creating services that are shaped by, and appropriate for, older people. Devolution and Structures of Government in Northern Ireland The Agreement (2) reached in the Multi-Party Negotiations in Belfast 1998 established the Northern Ireland Assembly which has full legislative authority for all transferred matters. The majority of social and economic public policy such as; agriculture, arts, education, health, environment and planning is determined by the Northern Ireland Assembly at Stormont. There are 11 Government Departments covering the main areas of responsibility with 108 elected Members of the Legislative Assembly (MLA�۪s). The powers of the Northern Ireland Assembly do not cover ��� reserved�۪ matters or ��� excepted�۪ matters . These are the responsibility of Westminster and include issues such as, tax, social security, policing, justice, defence, immigration and foreign affairs. Northern Ireland has 18 elected Members of Parliament (MP�۪s) to the House of Commons. Public Policy Context in Northern Ireland The economic, social and political consequence of an ageing population is a challenge for policy makers across government. Considering the complex and diverse causal factors that contribute to ageing in Northern Ireland, there are a number of areas of government policy at regional, national and international levels that are likely to impact in this area. International The Madrid International Plan of Action on Ageing (3) and the Research Agenda on Ageing for the 21st Century (4) provide important mechanisms for furthering research into ageing. The United Kingdom has signed up to these. The Madrid International Plan of Action on Ageing commits member states to a systematic review of the Plan of Action through Regional Implementation Strategies. The United Kingdom�۪s Regional Implementation Strategy covers Northern Ireland. National At National level, pension and social security are high on the agenda. The Pensions Act (5) became law in 2007 and links pensions increases with earnings as opposed to prices from 2012. Additional credits for people raising children and caring for older people to boost their pensions were introduced. Some protections are included for those who lost occupational pensions as a result of underfunded schemes being wound up before April 2005. In relation to State Pensions and benefits, this Act will bring changes to state pensions in future. The Act now places the Pension Credit element which is up-rated in line with or above earnings, on a permanent, statutory footing. Regional At regional level there are a number of age related public policy initiatives that have the potential to impact positively on the lives of older people in Northern Ireland. Some are specific to ageing such as the Ageing in an Inclusive Society (6) and others by their nature are cross-cutting such as Lifetime Opportunities: Governments Anti-Poverty Strategy for Northern Ireland (7). The main public policy framework in Northern Ireland is the Programme for Government: Building a Better Future, 2008-2011(PfG) (8) . The PfG, is the overarching high level policy framework for Northern Ireland and provides useful principles for ageing research and public policy in Northern Ireland. The PfG vision is to build a peaceful, fair and prosperous society in Northern Ireland, with respect for the rule of law. A number of Public Service Agreements (PSA) aligned to the PfG confirm key actions that will be taken to support the priorities that the Government aim to achieve over the next three years. For example objective 2 of PSA 7: Making Peoples�۪ Lives Better: Drive a programme across Government to reduce poverty and address inequality and disadvantage, refers to taking forward strategic action to promote social inclusion for older people; and to deliver a strong independent voice for older people. The Office of the First Minister and deputy First Minister (OFMDFM) have recently appointed an Interim Older People�۪s Advocate, Dame Joan Harbison to provide a focus for older peoples issues across Government. Ageing in an Inclusive Society is the cross-departmental strategy for older people in Northern Ireland and was launched in March 2005. It sets out the approach to be taken across Government to promote and support the inclusion of older people. The vision coupled with six strategic objectives form the basis of the action plans accompanying the strategy. The vision is: ���To ensure that age related policies and practices create an enabling environment, which offers everyone the opportunity to make informed choices so that they may pursue healthy, active and positive ageing.�۝ (Ageing in an Inclusive Society, Office of the First Minister and Deputy First Minister, 2005) Action planning and maintaining momentum across government in relation to this strategy has proved to be slower than anticipated. It is proposed to refresh this Strategy in line with Opportunity Age ��� meeting the challenges of ageing in the 21st Century (9). There are a number of policy levers elsewhere which can also be used to promote the positive aspects of an ageing society. The Investing for Health (10) and A Healthier Future:A 20 Year Vision for Health and Well-being in Northern Ireland (11), seek to ensure that the overall vision for health and wellbeing is achievable and provides a useful framework for ageing policy and research in the health area. These health initiatives have the potential to positively impact on the quality of life of older people and provide a useful framework for improving current policy and practice. In addition to public policy initiatives, the anti-discrimination frameworks in terms of employment in Northern Ireland cover age as well as a range of other grounds. Goods facilitates and services are currently excluded from the Employment Equality (age) Regulations (NI) 2006 (12). Supplementing the anti-discrimination measures, Section 75 of the Northern Ireland Act 1998 (13), unique to Northern Ireland, places a statutory obligation on public authorities in fulfilling their functions to promote equality of opportunity across nine grounds, one of which is age(14). This positive duty has the potential to make a real difference to the lives of older people in Northern Ireland. Those affected by policy decisions must be consulted and their interests taken into account. This provides an opportunity for older people and their representatives to participate in public policy-making, right from the start of the process. Policy and Research Interface ���Ageing research is vital as decisions in relation to policy and practice and resource allocation will be made on the best available information�۝. (CARDI�۪s Strategic Plan 2008-2011) As outlined earlier, CARDI has been established to bridge the gap to ensure that research reaches those involved in making policy decisions. CARDI is stimulating the ageing research agenda in Ireland through a specific research fund that has a policy and practice focus. My work is presently focusing on helping to build a greater awareness of the key policy levers and providing opportunities for those within research and policy to develop closer links. The development of this shared understanding by establishing these links between researchers and policy makers is seen as the best predictor for research utilization. It is important to acknowledge and recognise that researchers and policy makers operate in different institutional, political and cultural contexts. Research however needs to ���resonate�۪ with the contextual factors in which policy makers operate. Conclusions Those working within the public policy field recognise all too often that the development of government policies and initiatives in respect of age does not guarantee that they will result in changes in actual provision of services, despite Government recommendations and commitments. The identification of public policy initiatives as they relate to age has the potential to highlight persistent and entrenched difficulties that social policy has previously failed to address. Furthermore, the identification of these difficulties can maximise the opportunities for progressing these across government. A focus on developing effective and meaningful targets to ensure measurable outcomes in public policy for older people can assist in this. Access to sound, credible and up-to-date evidence will be vital in this respect. As well as a commitment to working across departmental boundaries to effect change.

Evaluation of methoprene effect on Aedes aegypti (Diptera: Culicidae) development in laboratory conditions

Several Brazilian Aedes aegypti populations are resistant to the larvicidae temephos. Methoprene, that inhibits adult emergence, is one of the alternatives envisaged by the Brazilian Dengue Control Program (PNCD). However, at Brazil vector infestation rates are measured through larvae indexes and it has been claimed that methoprene use in the field could face operational problems. In order to define a standardized protocol, methoprene effect was evaluated in laboratory conditions after continuous exposure of larvae (Rockefeller strain) to a methoprene formulation available to the PNCD. Methoprene-derived mortality occurs mainly at the pupa stage and pupa development is inversely proportional to methoprene concentration. Number and viability of eggs laid by treated and control females are equivalent. A methoprene dose-dependent delay in the development was noted; however, b correlations were found for total mortality or adult emergence inhibition if data obtained when all control mosquitoes have emerged are compared to data obtained when methoprene-treated groups finish development. The cumulative record of total methoprene-induced mortality at the time control adults emerge is proposed for routine evaluation of field populations. Mortality of all specimens, but not of larva, could account for adult emergence inhibition, confirming the inadequacy of larvae indexes to evaluate methoprene effect.
