    Although researchers argue for the importance of involving the public in developing health policy, there has been little focus on central research questions – such as what techniques of public participation work, in what circumstances, and why. This paper presents a realist synthesis which identifies and explains the underlying mechanisms and specific contextual factors that lead to effective public participation in health policy and planning. Peer-reviewed, English language literature was searched, which resulted in 77 articles for review and synthesis. This synthesis uncovered the underlying mechanism of ‘political commitment’ that generates public participation effectiveness. The other three possible underlying mechanisms, namely: ‘partnership synergy’, ‘inclusiveness’ and ‘deliberativeness’, were found to potentially provide further explanation on public participation effectiveness for health policy and planning. The findings of this review provide evidence that can be useful to health practitioners and decision-makers to actively involve the public when drafting public health policies and programs and, more importantly, guide them in deciding which strategies to best employ for which contexts

    AIM: To explore the relationship between actual and expected general medical practitioner (GP) practice prescribing rates for statins, angiotensin converting enzyme (ACE) inhibitors, and beta-blockers. BACKGROUND: There is a growing body of literature highlighting inequities in GP practice prescribing rates for many drug therapies. The equity of prescribing is of central importance in the area of therapeutics since it explores the interface between those patients who should and those who actually do receive a drug therapy. SETTING: Four primary care trusts (PCTs 1–4) in the North West of England, including 132 GP practices. METHODS: Actual and expected prescribing rates for statins, beta-blockers, and ACE inhibitors were specifically developed for each GP practice. RESULTS: There were no statistically significant correlations between actual and expected prescribing rates in PCT2 and PCT3, although in PCT1 there were statistically significant correlations for statins (0.286, p < 0.05) and ACE inhibitors (0.381, p < 0.01). In PCT4, correlations were moderate to high for beta-blockers (0.693, p < 0.01), and moderate for statins (0.541, p < 0.05) and ACE inhibitors (0.585, p < 0.01). Scatterplots highlighted large variations between individual GP practices (both within and between PCTs) in terms of the relationship between actual and expected prescribing rates. CONCLUSION: This paper highlights variability between PCTs and GP practices in terms of the relationship between actual and expected prescribing rates. The findings from this paper may further advance the suggestion of inequities in prescribing rates for coronary heart disease (CHD) drugs, and studies such as this may be repeated in different therapeutic areas, healthcare settings, and countries

    Food insecurity in South Australian single parents: an assessment of the livelihoods framework approach

    Get PDF
    Single parent households experience periods of food insecurity more frequently than other Australian families. Despite elevated risk, many single parents achieve food security with limited means. This article applies and evaluates the utility of the livelihoods framework approach as a tool for understanding food insecurity in this population and generating relevant policy recommendations. The approach is adapted here to provide insight into the skills, strategies and resource individuals use to attain or strive for food security. The framework incorporates these individual capabilities into a model of the social, economic and political structures and processes through which individuals navigate to attain food security. Semi-structured interviews were conducted with single parents living in rural and urban South Australia. Transcripts were analysed in an effort to populate a food security livelihoods framework for single parents. The livelihoods framework is found to be capable of reproducing the types and levels of capabilities reported in previous findings. Furthermore, it provides novel insight into the relationships that form between classes of capabilities and between capabilities and the structures and processes in which they are utilised. These insights are considered in terms of relevance to policy

    The effects of a propeller slipstream on the wing laminar boundary are being investigated. Hot-wire velocity sensor measurements have been performed in flight and in a wind tunnel. It is shown that the boundary layer cycles between a laminar state and a turbulent state at the propeller blade passage rate. The cyclic length of the turbulent state increases with decreasing laminar stability. Analyses of the time-varying velocity profiles show the turbulent state to lie in a transition region between fully laminar and fully turbulent. The observed cyclic boundary layer has characteristics similar to relaminarizing flow and laminar flow with external turbulence

    Characterization of VPS34-IN1, a selective inhibitor of Vps34, reveals that the phosphatidylinositol 3-phosphate-binding SGK3 protein kinase is a downstream target of class III phosphoinositide 3-kinase

    The Vps34 (vacuolar protein sorting 34) class III PI3K (phosphoinositide 3-kinase) phosphorylates PtdIns (phosphatidylinositol) at endosomal membranes to generate PtdIns(3)P that regulates membrane trafficking processes via its ability to recruit a subset of proteins possessing PtdIns(3)P-binding PX (phox homology) and FYVE domains. In the present study, we describe a highly selective and potent inhibitor of Vps34, termed VPS34-IN1, that inhibits Vps34 with 25 nM ICin vitro, but does not significantly inhibit the activity of 340 protein kinases or 25 lipid kinases tested that include all isoforms of class I as well as class II PI3Ks. Administration of VPS34-IN1 to cells induces a rapid dose-dependent dispersal of a specific PtdIns(3)P-binding probe from endosome membranes, within 1 min, without affecting the ability of class I PI3K to regulate Akt. Moreover, we explored whether SGK3 (serum- and glucocorticoid-regulated kinase-3), the only protein kinase known to interact specifically with PtdIns(3)P via its N-terminal PX domain, might be controlled by Vps34. Mutations disrupting PtdIns(3)P binding ablated SGK3 kinase activity by suppressing phosphorylation of the T-loop [PDK1 (phosphoinositide-dependent kinase 1) site] and hydrophobic motif (mammalian target of rapamycin site) residues. VPS34-IN1 induced a rapid ~50-60% loss of SGK3 phosphorylation within 1 min. VPS34-IN1 did not inhibit activity of the SGK2 isoform that does not possess a PtdIns(3)P-binding PX domain. Furthermore, class I PI3K inhibitors (GDC-0941 and BKM120) that do not inhibit Vps34 suppressed SGK3 activity by ~40%. Combining VPS34-IN1 and GDC-0941 reduced SGK3 activity ~80-90%. These data suggest SGK3 phosphorylation and hence activity is controlled by two pools of PtdIns(3)P. The first is produced through phosphorylation of PtdIns by Vps34 at the endosome. The second is due to the conversion of class I PI3K product, PtdIns(3,4,5)P3 into PtdIns(3)P, via the sequential actions of the PtdIns 5-phosphatases [SHIP1/2 (Src homology 2-domain-containing inositol phosphatase 1/2)] and PtdIns 4-phosphatase [INPP4B (inositol polyphosphate 4-phosphatase type II)]. VPS34-IN1 will be a useful probe to delineate physiological roles of the Vps34. Monitoring SGK3 phosphorylation and activity could be employed as a biomarker of Vps34 activity, in an analogous manner by which Akt is used to probe cellular class I PI3K activity. Combining class I (GDC-0941) and class III (VPS34-IN1) PI3K inhibitors could be used as a strategy to better analyse the roles and regulation of the elusive class II PI3K

    Do Your Patients Trust You?

    oai:ojs.amj.titandemo.com:article/7The trust that patients invest in healthcare professionals and their advice has been shown to facilitate positive clinical outcomes, although there is evidence that patient trust in expertise, including healthcare professionals, has been declining over the years. Questions about whether or not to trust healthcare professionals have been raised recently in international media by Australian pop icon Kylie Minogue, who spoke of her alleged initial misdiagnosis with breast cancer and went on to tell women that they should ‘follow their intuition’ rather than placing unquestioning trust in doctors or medical advice. Given the power of the media in shaping public opinion, there is a potential for such stories to further impact on the already potentially friable doctor-patient relationships, with questions of trust taking centre-stage. Therefore, an understanding of the nature of trust, in addition to the reasons for the decline in patient trust, is exceedingly important for health professionals. This paper presents an overview of social theories of trust that provide a lens through which we can analyse the development of mistrust in healthcare, and identifies ways in which healthcare professionals may aim to facilitate and sustain patient trust

    Innervation of gonadotropin-releasing hormone neurons by peptidergic neurons conveying circadian or energy balance information in the mouse

    Get PDF
    Background: Secretion of gonadotropin-releasing hormone (GnRH) produced in neurons in the basal forebrain is the primary regulator of reproductive maturation and function in mammals. Peptidergic signals relating to circadian timing and energy balance are an important influence on the reproductive axis. The aim of this study was to investigate the innervation of GnRH neurons by peptidergic neurons. Methodology/Principal Findings: Immunohistochemistry and confocal microscopy were used to detect appositions of peptidergic fibers (NPY, β-endorphin, MCH) associated with energy balance and metabolic status in transgenic mice expressing a green fluorescent protein reporter construct in GnRH neurons. The frequency of these appositions was compared to those of vasoactive intestinal peptide (VIP), a hypothalamic neuropeptide likely to convey circadian timing information to the GnRH secretory system. The majority of GnRH neurons (73-87%) were closely apposed by fibers expressing NPY, β-endorphin, or MCH, and a significant proportion of GnRH neurons (28%) also had close contacts with VIP-ir fibers. Conclusions/Significance: It is concluded that GnRH neurons in the mouse receive a high frequency of direct modulatory inputs from multiple hypothalamic peptide systems known to be important in conveying circadian information and signalling energy balance. © 2009 Ward et al
