    The increasing prevalence of mental illness in the United States presents significant challenges for primary care providers in low-income settings. Integrated Behavioral Health (IBH) programs have resulted in improved general health for low-income participants; however, managing appointment adherence, in which the patient attends appointment as scheduled, is particularly challenging. The purpose of this pilot project was to implement bundled interventions at a low-income primary care clinic to improve patient adherence to behavioral health treatment. The bundle of interventions included: 1) educational interventions emphasizing the benefits of IBH care 2) warm patient handoffs between the primary care provider to a behavioral health specialist at the primary care appointment, and 3) follow-up calls by behavioral health counselors for missed appointments. After the introduction of interventions, the average number of patients who no-showed for their appointment decreased by 60%, and the average number of patients who cancelled decreased by 15%. These differences were significant (x2 = 9.263, df = 2, p \u3c 0.01). This pilot project showed that patients who were exposed to the bundle were more likely to keep their appointments and less likely to miss

    ‘Our voice started off as a whisper and now it is a great big roar’ : The Salford Dementia Associate Panel as a model of involvement in research activities

    Get PDF
    This paper presents the work of the ‘Salford Dementia Associate Panel’, based at the Salford Institute for Dementia, Salford University (UK). We discuss the roles of the Dementia Associates, in particular around the areas of engagement and research. The panel is made up of people living with dementia, and current and former care partners. It highlights the development of this group over a four-year period and demonstrates over time how the role of a Dementia Associate member has evolved. The panel is involved in research, education and public engagement activities conducted by staff and students within the Institute. The motivations for becoming involved are clearly articulated and demonstrate how the personal backgrounds of individuals have driven the collective involvement and desire to bring about change. The benefits and challenges associated with working as part of a panel are discussed. We conclude by bringing together our experiences as a set of suggestions for others who may wish to create a similar forum to promote the involvement of people living with dementia and former and current care partners

    Copper-zinc superoxide dismutase (SOD) is present in relatively high concentrations in the β-cells of human islets. The activity of the extracted enzyme is partially inhibited upon incubation with the diabetogenic drugs alloxan, streptozotocin, or Vacor. The role of this enzyme in protecting β-cells against chemically induced diabetes was further investigated. Incubation of intact canine islets with alloxan (0.2 mg/ml) and 4 mM glucose decreased the insulin secretory response by 87% during subsequent exposure to 28 mM glucose. Concomitantly the SOD-specific activity (units of enzyme activity per milligram immunoreactive SOD) decreased 50% in alloxan-exposed islets. When islets were protected from alloxan toxicity by including 28 mM glucose with alloxan, the insulin secretory response and SOD specific activity remained identical to controls. Thus, SOD specific activity correlates with maintenance of β-cell function. To test the effectiveness of SOD against streptozotocin in vitro, canine islets were incubated 10 min with or without streptozotocin (0.1 mg/ml) with 4 mM glucose; their functional integrity was tested subsequently as the insulin secretory response to 28 mM glucose. Exposure to streptozotocin alone decreased the response by 70%; inclusion of SOD (1.5 mg/ml) before and during exposure to streptozotocin completely prevented this effect. Cyanide-inactivated SOD was not effective. The potential of SOD to prevent streptozotocin-induced diabetes was tested in rats in vivo. SOD injected 10 s or 50 min before streptozotocin prevented or significantly attenuated diabetes. Injection of SOD and streptozotocin simultaneously was much less effective, and cyanide-inactivated SOP was ineffective. No protection was afforded by injection of SOD 12 or 24 h before streptozotocin. Our results support hypotheses that (a) oxygen radicals mediate the β-cell toxicity of both alloxan and streptozotocin, and (b) β-cells may be particularly vulnerable to oxygen radical damage

    Investigation of the use of inertial sensing equipment for the measurement of hip flexion and pelvic rotation in horse riders

    Equestrian sports report three to five times higher incidence rates for lower back pain than that of the general population, with hip flexion angles of 50-60° suggested as a causal factor. Inertial motion capture technology enables dynamic measurement of rider kinematics but data extraction is time-consuming. The aim of this study was to develop a software tool to automate the process of extracting biomechanical data from the XsensTM MVN (MoCap) system to investigate postural changes in riders, comparing static position at halt with dynamic position during the sit phase of rising trot. The software was found to be efficient, reducing data extraction time by 97% when used with a sample of 16 riders. Good correlation was found between hip flexion and pelvic anterior-posterior rotation and between halt and trot but with significantly greater values of hip flexion and pelvic anterior rotation in trot. No riders showed hip flexion >50° at halt but 11 riders (69%) showed hip flexion >50° during the sit phase of rising trot, indicating that dynamic assessment is important when considering rider postural faults that may put them at risk of back injury. Keywords: Hip flexion, Horse rider, Inertial sensor, Motion capture, Pelvic rotatio

    The precautions of clinical waste: disposable medical sharps in the United Kingdom

    Get PDF
    This article deals with recent changes in UK guidance on clinical waste, in particular a shift to disposable, single-use instruments and sharps. I use interviews conducted with nurses from a GP practice and two clinical waste managers at alternative treatment and incineration sites as a springboard for reflection on the relationship between the legislation on clinical waste management and its implementation. Scrutinizing the UK guidance, European legislation and World Health Organization principles, I draw out interviewees’ concerns that the changed practices lead to an expansion of the hazardous waste category, with an increased volume going to incineration. This raises questions regarding the regulations’ environmental and health effects, and regarding the precautionary approach embedded in the regulations. Tracing the diverse reverberations of the term ‘waste’ in different points along the journeys made by sharps in particular, and locating these questions in relation to existing literature on waste, I emphasize that public health rationales for the new practices are not made clear in the guidance. I suggest that this relative silence on the subject conceals both the uncertainties regarding the necessity for these means of managing the risks of infectious waste, and the tensions between policies of precautionary public health and environmental sustainability

    A simple method for implementing Monte Carlo tests

    Get PDF
    We consider a statistical test whose p value can only be approximated using Monte Carlo simulations. We are interested in deciding whether the p value for an observed data set lies above or below a given threshold such as 5%. We want to ensure that the resampling risk, the probability of the (Monte Carlo) decision being different from the true decision, is uniformly bounded. This article introduces a simple open-ended method with this property, the confidence sequence method (CSM). We compare our approach to another algorithm, SIMCTEST, which also guarantees an (asymptotic) uniform bound on the resampling risk, as well as to other Monte Carlo procedures without a uniform bound. CSM is free of tuning parameters and conservative. It has the same theoretical guarantee as SIMCTEST and, in many settings, similar stopping boundaries. As it is much simpler than other methods, CSM is a useful method for practical applications

    Corporate Governance in Financial Institutions

    On 29th - 30th March 2007, SUERF and the Central Bank of Cyprus jointly organized a Seminar: Corporate Governance in Financial Institutions. The papers in the present publication are based on a sample of the presentations at the Seminar. Together, the papers illuminate a number of key issues in corporate governance in a variety of financial firms. In the first paper based on a keynote address, Spyros G. Stavrinakis, Central Bank of Cyprus gives an overview of the legal framework for corporate governance in financial institutions in Cyprus. According to a Central BankDirective issued in 2006, implementation of corporate governance principles is mandatory for all banks incorporated in Cyprus and their overseas branches and for some Cyprus branches of foreign banks domiciled outside the European Economic Area. Banks are obliged to have a robust internal governance framework, consistent lines of reporting and effective risk identification, management, monitoring and reporting procedures for all the risks to which credit institutions are actually or potentially exposed. The board of directors should take the lead in establishing and approving ethical standards and corporate values for itself and for the bank's senior executive management. Potential conflicts of interest should be identified, prevented or appropriately managed. Each bank should maintain a compliance function that monitors compliance with rules, regulations and policies. Clear lines of responsibility and accountability should be set and enforced. New members of the board of directors as well as the senior executive managers of banks have to be vetted and approved by the Central Bank of Cyprus for their " fitness and properness." In order to ensure transparency concerning the implementation of the principles, each bank's corporate governance framework should be disclosed in the bank's annual report and on its public website. In the second paper by Christian Harm, University of Muenster, "The Governance of the Banking Firm" the author builds on the literatures on corporate governance and financial regulation. In relation to governance of financial institutions, agency theory has both merits and shortcomings. It provides good explanations in many delegation situations but it has severe difficulties in dealing with institutions with several stakeholders and complex objective functions for the management. Firms guided by shareholder value may work more effectively than firms guided by stakeholder cacophony. Depositors are important stakeholders in banks. Since they are typically incapable of managing the supervision of their claims on the bank, they rely on regulators to do it for them. Remuneration systems for bank managers should provide proper incentives. According to the author, incentives should be structured such as to reward particular strategic achievements. Banks can apply executive stock option plans, but should confine options to a secondary place behind other long-term incentives based on success criteria that further shareholder interests without compromising the regulatory mission. Such an incentive framework tends, however, to be very complex so that the general ambiguities associated with the concept of governance could imply that in the banking firm, selecting managers with a proper intrinsic motivation may be superior to defining complex remuneration programs. In the third paper "Corporate Governance Issues in Non-Shareholder Value Financial Institutions: ACase Study of Mutual Building Societies in the UK", David T. Llewellyn, Loughborough University, focuses on corporate governance in non-incorporated financial firms. The author describes the relevant stakeholders and the nature of agency problems in different types of financial firms. He compares monitoring mechanisms, incentives, abilities and feasibilities of managers and members of mutuals. Mutuality raises specific corporate governance issues: Corporate governance is less clearly defined because the firm's objectives are less clearly defined. Conflicts of interest between managers and owners are less easily identified and it is more difficult to create management incentives. The almost exclusive source of capital is retained profits and each member has a non-exclusive and non-marketable claim to residual net worth. Voting rights are typically not proportional to the size of the ownership stake. There is no market in ownership claims and therefore no effective market in corporate control. Consequently, there is ample scope for mutuals to be inefficient. There is, however, no evidence that the efficiency and performance of mutuals are poorer that that of incorporated financial firms. In the fourth paper "Corporate Governance in Emerging Market Banks", Bridget Gandy, Fitch Ratings Ltd., and her co-authors from the rating agency look at the framework for corporate governance of banks in a sample of emerging market countries. Since the crisis in the late 1990s in Latin America and Asia, there has been a marked improvement in corporate governance of financial institutions in the regions under observation. Many countries have taken legal steps to develop functioning market economies with a view to the need to satisfy the demands of international capital markets. Several banks have listed their shares on stock exchanges in developed markets and foreign bank ownership and involvement in local banking systems have increased. In Central and Eastern Europe, countries' desire for EU-accession has impacted on the development of their corporate governance systems. At the individual bank level, Fitch Ratings looks at bank board independence and quality, oversight and the importance of related party transactions, the integrity of the audit process, acceptability of executive and director remuneration, ownership structures and transparency. In evaluating the quality of governance at the country level, the authors apply a three-pillar approach in line with Montesquieu: Powers and responsibilities need to be separated between a representative legislature, a competent and accountable executive branch and a fair and independent judiciary. The paper contains an interesting table in which a number of key regulatory initiatives in a sample of emerging market countries are compared. The authors point out that large scale privatizations have reduced the importance of state-owned banks in many countries. There are, however, still several examples with complex holding structures involving banks with potential negative implications for corporate governance quality and problems with related party transactions. Acquisitions by foreign banks with developed corporate governance standards have generally had a positive impact and also listing of bank shares on foreign stock exchanges with tough disclosure and transparency requirements have contributed positively to the quality of corporate governance in emerging market banks. Read together, the four papers give a good overview of the development of corporate governance practices and remaining problems in financial institutions of different types and with domicile in different countries

    Latrepirdine: Molecular mechanisms underlying potential therapeutic roles in Alzheimer’s and other neurodegenerative diseases

    Get PDF
    Latrepirdine (DimebonTM) was originally marketed as a non-selective antihistamine in Russia. It was repurposed as an effective treatment for patients suffering from Alzheimer’s disease (AD) and Huntington’s disease (HD) following preliminary reports showing its neuroprotective functions and ability to enhance cognition in AD and HD models. However, latrepirdine failed to show efficacy in phase III trials in AD and HD patients following encouraging phase II trials. The failure of latrepirdine in the clinical trials has highlighted the importance of understanding the precise mechanism underlying its cognitive benefits in neurodegenerative diseases before clinical evaluation. Latrepirdine has shown to affect a number of cellular functions including multireceptor activity, mitochondrial function, calcium influx and intracellular catabolic pathways; however, it is unclear how these properties contribute to its clinical benefits. Here, we review the studies investigating latrepirdine in cellular and animal models to provide a complete evaluation of its mechanisms of action in the central nervous system. In addition, we review recent studies that demonstrate neuroprotective functions for latrepirdine-related class of molecules including the β-carbolines and aminopropyl carbazoles in AD, Parkinson’s disease and amyotrophic lateral sclerosis models. Assessment of their neuroprotective effects and underlying biological functions presents obvious value for developing structural analogues of latrepirdine for dementia treatment
