Health Impact Assessment contributing to Healthy Public Policy

Published by Public Health, April 2009 IPH recently coordinated and was guest editor for a minisymposium on Health Impact Assessment for the journal, Public Health. Three aricles contributed to the minisymposium which included an article from IPH on how HIA can contribute to healthy public policy. An article reviewing the right to the highest attainable standard of health from Paul Hunt and Gillian MacNaughton and a review of the strengths and weakneses of quantitiative methods used in HIA from Emer O'Connell and Fintan Hurley. The minisymposium evolved from the 8th International HIA conference ‘Healthy Public Policy – is Health Impact Assessment the Cornerstone’ hosted by IPH.

Review of Health Impact Assessment

IPH commissioned a review of HIA work in 2009 to detail progress and achievements of HIA from 2001.  This included an assessment of current levels of HIA awareness and activity and suggestions for the direction of future work.

Consideration of health in Strategic Environment Assessment (SEA) on the island of Ireland

This IPH report explores the extent health was incorporated into SEA in a manner which would suggest a good understanding of the many social and economic factors which strongly influence health. The research identifies that a consideration of health is not routinely included in SEAs. There is a need to build capacity and change mindsets in how SEAs are undertaken to more completely factor in the health impacts.

QuantiFERON®-CMV assay for the assessment of cytomegalovirus cell-mediated immunity.

Cytomegalovirus (CMV) infection has historically been a major complication among immunocompromised patients, such as solid-organ and stem-cell transplant recipients and patients with advanced HIV infection. While the introduction of antiretroviral therapy has almost eradicated CMV infection in HIV-infected patients, CMV disease remains a significant problem in transplant recipients once antiviral prophylaxis is discontinued. QuantiFERON(®)-CMV allows the assessment of cellular immunity against CMV by detecting the production of IFN-γ following in vitro stimulation with CMV antigens. Preliminary studies have shown a correlation between a lack of detectable cell-mediated immunity measured by the QuantiFERON-CMV assay and a higher incidence of CMV infection and disease in immunocompromised patients. Measurement of cell-mediated immunity against CMV appears to be a promising strategy to identify patients at highest risk for the development of CMV disease and, therefore, to individualize preventive strategies for CMV in transplant recipients.

IPH response to the Environmental Protection Agency Consultation on Stategic Environmental Assessment (SEA) Process Checklist

The Institute of Public Health in Ireland is an all-island body which aims to improve health in Ireland by working to combat health inequalities and influence public policies in favour of health. The Institute promotes co-operation in research, training, information and policy in order to contribute to policies which tackle inequalities in health. Over the past six years the Institute has worked closely with the Department of Health and Children and the Department of Health, Social Services and Public Safety in Northern Ireland to build capacity for Health Impact Assessment. The Institute takes the view that health is determined by policies, plans and programmes in many sectors outside the health sector as well as being dependent on access to and availability of first class health services. The importance of other sectors is encapsulated in a social determinants of health perspective which recognises that health is largely shaped and influenced by the physical, social, economic and cultural environments in which people live, work and play. Figure 1 illustrates these multi-dimensional impacts on health and also serves to highlight the clear and inextricable links between health and sustainable development. Factors that impact on long-term sustainability will thus also impact on health.

Response to Draft Guidance on Health in Strategic Environmental Assessment

The Institute of Public Health in Ireland welcomes the opportunity to comment on the Draft Guidance on Health in Strategic Environmental Assessment.  Our organisation aims to improve health on the island of Ireland by working to combat health inequalities and influence public policies in favour of health. The Institute applies a holistic model of health which emphasises a wide range of health determinants, including economic, environmental, social and biological factors. Our work is based on the premise that improving health and reducing health inequalities can only be achieved through addressing these broad determinants of health.

Proposed Sugar Sweetened Drinks Tax: Health Impact Assessment

The Institute of Public Health in Ireland (IPH) was requested by the Department of Health (RoI) to undertake a Health Impact Assessment (HIA) of a proposed tax on sugar sweetened drinks (SSDs) in 2012. The public health priority for this proposal was to consider the potential of such a tax to address the problem of overweight and obesity in Ireland. The HIA was overseen by the Special Action Group on Obesity (SAGO) and guided by a steering group. The HIA process involved a population profile, a stakeholder consultation event and a literature review. This information, paralleled by a modelling exercise undertaken by Dr. Mike Rayner and his team in the University of Oxford was presented to the steering group to inform their conclusions.

Assessment and analysis of mechanical allodynia-like behavior induced by spared nerve injury (SNI) in the mouse

Rrésumé: La première description dans une publication médicale des douleurs neuropathiques remonte à 1872, le Dr S.W. Mitchell les résumant ainsi [...]" la causalgie est la plus terrible des tortures qu'une lésion nerveuse puisse entraîner "[...]. Par définition, la douleur neuropathique est une douleur chronique faisant suite à une lésion ou dysfonction du système nerveux. Malgré les progrès faits dans la compréhension de ce syndrome, le détail des mécanismes impliqués nous échappe encore et son traitement reste insuffisant car moins de 50% des patients sont soulagés par les thérapies actuelles. Différents modèles expérimentaux ont été élaborés chez l'animal de laboratoire, en particulier des modèles de lésion de nerfs périphériques chez le rat, permettant des investigations tant moléculaires que fonctionnelles des mécanismes impliqués dans le développement de ces douleurs. En revanche, peu de modèles existent chez la souris, alors que cet animal, grâce à la transgénèse, est très fréquemment utilisé pour l'approche fonctionnelle ciblée sur un gène. Dans l'étude présentée ici, nous avons évalué chez la souris C57BL/6 l'adaptation d'un modèle neuropathique, proposé une nouvelle modalité de mesure de la sensibilité douloureuse adaptée à la souris et défini une méthode d'analyse performante des résultats. Ce modèle, dit de lésion avec épargne nerveuse (spared Werve injury, SNI), consiste en la lésion de deux des trois branches du nerf sciatique, soit les nerfs peronier commun et tibial. La troisième branche, le nerf sural est laissé intact et c'est dans le territoire cutané de ce dernier que la sensibilité douloureuse à des stimulations mécaniques est enregistrée. Des filaments calibrés de force croissante sont appliqués sur la surface de la patte impliquée et la fréquence relative de retrait de la patte a été modélisée mathématiquement et analysée par un modèle statistique intégrant tous les paramètres de l'expérience (mixed-effects model). Des variantes chirurgicales lésant séquentiellement les trois branches du nerf sciatique ainsi que la réponse en fonction du sexe de l'animal ont également été évaluées. La lésion SNI entraîne une hypersensibilité mécanique marquée comparativement aux souris avec chirurgie contrôle; cet effet est constant entre les animaux et persiste durant les quatre semaines de l'étude. De subtiles différences entre les variables, y compris une divergence de sensibilité mécanique entre les sexes, ont été démontrées. La nécessité de léser le nerf tibial pour le développement des symptômes a également été documentée par notre méthode d'évaluation et d'analyse. En conclusion, nous avons validé le modèle SNI chez la souris par l'apparition d'un symptôme reproductible et apparenté à l'allodynie mécanique décrite par les patients souffrant de douleurs neuropathiques. Nous avons développé des méthodes d'enregistrement et d'analyse de la sensibilité douloureuse sensibles qui permettent la mise en évidence de facteurs intrinsèques et extrinsèques de variation de la réponse. Le modèle SNI utilisé chez des souris génétiquement modifiées, de par sa précision et reproductibilité, pourra permettre la discrimination de facteurs génétiques et épigénétiques contribuant au développement et à la persistance de douleurs neuropathiques.

Initial assessment of safety and clinical feasibility of irreversible electroporation in the focal treatment of prostate cancer.

BACKGROUND: To evaluate the safety and clinical feasibility of focal irreversible electroporation (IRE) of the prostate. METHODS: We assessed the toxicity profile and functional outcomes of consecutive patients undergoing focal IRE for localised prostate cancer in two centres. Eligibility was assessed by multi-parametric magnetic resonance imaging (mpMRI) and targeted and/or template biopsy. IRE was delivered under transrectal ultrasound guidance with two to six electrodes positioned transperineally within the cancer lesion. Complications were recorded and scored accordingly to the NCI Common Terminology Criteria for Adverse Events; the functional outcome was physician reported in all patients with at least 6 months follow-up. A contrast-enhanced MRI 1 week after the procedure was carried out to assess treatment effect with a further mpMRI at 6 months to rule out evidence of residual visible cancer. RESULTS: Overall, 34 patients with a mean age of 65 years (s.d.=±6) and a median PSA of 6.1 ng ml(-1) (interquartile range (IQR)= 4.3-7.7) were included. Nine (26%), 24 (71%) and 1 (3%) men had low, intermediate and high risk disease, respectively (D'Amico criteria). After a median follow-up of 6 months (range 1-24), 12 grade 1 and 10 grade 2 complications occurred. No patient had grade >/= 3 complication. From a functional point of view, 100% (24/24) patients were continent and potency was preserved in 95% (19/20) men potent before treatment. The volume of ablation was a median 12 ml (IQR=5.6-14.5 ml) with the median PSA after 6 months of 3.4 ng ml(-1) (IQR=1.9-4.8 ng ml(-1)). MpMRI showed suspicious residual disease in six patients, of whom four (17%) underwent another form of local treatment. CONCLUSIONS: Focal IRE has a low toxicity profile with encouraging genito-urinary functional outcomes. Further prospective development studies are needed to confirm the functional outcomes and to explore the oncological potential.
