  The Interim Report of the National Task Force on suicide was published in September 1996.  The Report addressed the first two terms of reference, to define numerically and qualitatively, the nature of the suicide problem in Ireland and to define and quantify the problems of attempted suicide and parasuicide in Ireland including the associated costs involved.  The remaining terms of reference of the Task Force will now be addressed:- Download the Report here

The Minister for Health and Children established the Task Force on Sudden Cardiac Death (SCD) in the Autumn of 2004, with the following terms of reference:1) Define SCD and describe its incidence and underlying causes in Ireland.2) Advise on the detection and assessment of those at high risk of SCD and their relatives.3) Advise on the systematic assessment of those engaged in sports and exercise for risk of SCD.4) Advise on maximizing access to basic life support (BLS) and automated external defibrillators (AEDs) and on:- appropriate levels of training in BLS and use of AEDs, and on the maintenance of that training- priority individuals and priority groups for such training- geographic areas and functional locations of greatest need- best practice models of first responder scheme and public access defibrillation, and- integration of such training services.5) Advise on the establishment and maintenance of surveillance systems, including a registry of SCD and information systems to monitor risk assessment, and training and equipment programmes.6) Advise and make recommendations on other priority issues relevant to SCD in Ireland.7) Outline a plan for implementation and advise on monitoring the implementation of recommendations made in the Task Force’s report. In undertaking its work the Task Force was mindful of national health policy, relevant national strategies and of the recently reformed structures for health service delivery in Ireland.

Les médias de masse, en particulier Internet, ont profondément modifié la distribution du pouvoir dans notre société. Sous l'oeil des caméras et des citoyens-reporters, le pouvoir policier est l'objet d'une intense « sous-veillance » publique et médiatique. Pourquoi et comment sensibiliser les nouveaux entrants aux « risques médiatiques » de leur future profession ?

In Chagas disease serious cardiac dysfunction can appear. We specifically studied the cardiac function by evaluating: ventricle contractile force and norepinephrine response, affinity and density of beta-adrenergic receptors, dynamic properties of myocardial membranes, and electrocardiography. Albino swiss mice (n = 250) were infected with 55 trypomastigotes, Tulahuen strain and studied at 35, 75, and 180 days post-infection, that correspond to the acute, indeterminate, and chronic phase respectively. Cardiac beta-adrenergic receptors' affinity, myocardial contractility, and norepinephrine response progressively decreased from the acute to the chronic phase of the disease (p < 0.01). The density (expressed as fmol/mg.prot) of the receptors was similar to non-infected mice (71.96 ± 0.36) in both the acute (78.24 ± 1.67) and indeterminate phases (77.28 ± 0.91), but lower in the chronic disease (53.32 ± 0.71). Electrocardiographic abnormalities began in the acute phase and were found in 65% of the infected-mice during the indeterminate and chronic phases. Membrane contents of triglycerides, cholesterol, and anisotropy were similar in all groups. A quadratic correlation between the affinity to beta-adrenergic receptors and cardiac contractile force was obtained. In conclusion the changes in cardiac beta-adrenergic receptors suggests a correlation between the modified beta-adrenergic receptors affinity and the cardiac contractile force.

The North Dublin City and County Regional Drugs Task Force invites applications for this once-off funding which will be provided through four pillars by way of a grant up to €3,000 for innovative initiatives: • Prevention, Education & Awareness – to develop programmes and supports in the community which offer information and education in order to generate awareness. • Treatment & Rehabilitation – to develop additional short-term supports for those undertaking treatment for drug misuse or innovative rehabilitative supports. • Research – to undertake local research into drug misuse in North Dublin within the RDTF area. • Supply Reduction – to reduce access to all drugs, in particular those that cause most harm, among young people in neighbourhoods where misuse is most prevalent. Terms and conditions apply. To request an application pack or for more information contact 01 813 1786 orThis resource was contributed by The National Documentation Centre on Drug Use.

Chronic growth hormone (GH) hypersecretion in rats leads to increased isometric force without affecting the unloaded shortening velocity of isolated cardiac papillary muscles, despite a marked isomyosin shift toward V3. To determine if alterations occurred at the level of the contractile proteins in rats bearing a GH-secreting tumor (GH rats), we examined the mechanical properties of skinned fibers to eliminate the early steps of the excitation-contraction coupling mechanism. We found that maximal active tension and stiffness at saturating calcium concentrations (pCa 4.5) were markedly higher in GH rats than in control rats (tension, 52.9 +/- 5.2 versus 38.1 +/- 4.6 mN.mm-2, p < 0.05; stiffness, 1,105 +/- 120 versus 685 +/- 88 mN.mm-2.microns-1, p < 0.01), whereas values at low calcium concentrations (pCa 9) were unchanged. In addition, the calcium sensitivity of the contractile proteins was slightly but significantly higher in GH rats than in control rats (delta pCa 0.04, p < 0.001). The crossbridge cycling rate, reflected by the response to quick length changes, was lower in GH rats than in control rats (62.0 +/- 2.6 versus 77.4 +/- 6.6 sec-1, p < 0.05), in good agreement with a decrease in the proportion of alpha-myosin heavy chains in the corresponding papillary muscles (45.5 +/- 2.0% versus 94.6 +/- 2.4%, p < 0.001). The changes in myosin heavy chain protein phenotype were paralleled by similar changes of the corresponding mRNAs, indicating that the latter occurred mainly at a pretranslational level. These results demonstrate that during chronic GH hypersecretion in rats, alterations at the myofibrillar level contribute to the increase in myocardial contractility observed in intact muscle.

Workforce planning identifies the composition of the workforce required to deliver health service goals. It encompasses a range of human resource activities aimed at the short, medium and long-term. Workforce planning that is integrated with service and financial planning offers the best opportunity for linking human resource decisions to the strategic goals for the health services. Systems and structures are required to support and develop workforce planning activities
