    In the last 20 years, expenditures on pharmaceuticals - as well as total health expenditures - have grown faster than the gross national product in all European countries. The aim of this paper was to review policies that European governments apply to reduce or at least slow down public expenditure on pharmaceutical products. Such policies can target the industry, the wholesalers and retailers, prescribers, and patients. The objectives of pharmaceutical policies are multidimensional and must take into account issues relating to public health, public expenditure and industrial incentives. Both price levels and consumption patterns determine the level of total drug expenditure in a particular country, and both factors vary greatly across countries. Licensing and pricing policies intend to influence the supply side. Three types of pricing policies can be recognised: product price control, reference pricing and profit control. Profit control is mainly used in the UK. Reference pricing systems were first used in Germany and The Netherlands and are being considered in other countries. Product price control is still the most common method for establishing the price of drugs. For the aim of fiscal consolidation, price-freeze and price-cut measures have been frequently used in the 1980s and 1990s. They have affected all types of schemes. For drug wholesalers and retailers, most governments have defined profit margins. The differences in price levels as well as the introduction of a Single European Pharmaceutical Market has led to the phenomenon of parallel imports among member countries of the European Union. This may be facilitated by larger and more powerful wholesalers and the vertical integration between wholesalers and retailers. To control costs, the use of generic drugs is encouraged in most countries, but only few countries allow pharmacists to substitute generic drugs for proprietary brands. Various interventions are used to reduce the patients' demand for drugs by

    Discrimination and inequality shape women's experiences of drug use and in the drug trade and the impact of drug control efforts on them, with disproportionate burdens faced by poor and otherwise marginalized women. In recent years, UN member states and UN drug control and human rights entities have recognized this issue and made commitments to integrate a 'gender perspective' into drug control policies, with 'gender' limited to those conventionally deemed women. But the concept of gender in international law is broader, rooted in socially constructed and culturally determined norms and expectations around gender roles, sex, and sexuality. Also, drug control policies often fail to meaningfully address the specific needs and circumstances of women (inclusively defined), leaving them at risk of recurrent violations of their rights in the context of drugs. This article explores what it means to 'mainstream' this narrower version of gender into drug control efforts, using as examples various women's experiences as people who use drugs, in the drug trade, and in the criminal justice system. It points to international guidelines on human rights and drug control as an important tool to ensure attention to women's rights in drug control policy design and implementation.

  3. How Drug Control Policy and Practice Undermine Access to Controlled Medicines.

    Drug conventions serve as the cornerstone for domestic drug laws and impose a dual obligation upon states to prevent the misuse of controlled substances while ensuring their adequate availability for medical and scientific purposes. Despite the mandate that these obligations be enforced equally, the dominant paradigm enshrined in the drug conventions is an enforcement-heavy criminal justice response to controlled substances that prohibits and penalizes their misuse. Prioritizing restrictive control is to the detriment of ensuring adequate availability of and access to controlled medicines, thereby violating the rights of people who need them. This paper argues that the drug conventions' prioritization of criminal justice measures-including efforts to prevent non-medical use of controlled substances-undermines access to medicines and infringes upon the right to health and the right to enjoy the benefits of scientific progress. While the effects of criminalization under drug policy limit the right to health in multiple ways, we draw on research and documented examples to highlight the impact of drug control and criminalization on access to medicines. The prioritization and protection of human rights-specifically the right to health and the right to enjoy the benefits of scientific progress-are critical to rebalancing drug policy.

  5. The politics of drug control in Nigeria: Exclusion, repression and obstacles to policy change.

    Klantschnig, Gernot

    2016-04-01

    International agencies have viewed West Africa as a major player in the global trade in cocaine and heroin and in efforts to control that trade, as there have been reports of escalating arrests of drug smugglers, large-scale drug seizures and 'narco-states' in the subregion. It is claimed that a substantial share of the drugs available in Western markets transit through West Africa today and are increasingly used there as well. Notwithstanding this growing alarm, there is little serious scholarship addressing the issue of drugs and drug policy in West Africa. The article assesses and challenges some of the existing depictions of drugs and drug policy in West Africa through an empirical case study of drug control in Nigeria - one of West Africa's most notorious 'drug hubs' and recently hailed as a policy model by international experts. Based on previously inaccessible government documents, interviews with key officials in Nigeria, as well as ethnographic work at Nigeria's key drug agency, the article provides a unique insight into the politics of drug policy-making and implementation in West Africa. After describing the dominant official narratives of Nigeria's drug control, the article shows how the key political dynamics underlying drug policy remain obscured by these narratives. Nigerian drug policy has been characterised by a highly exclusive policy-making process, repression as the sole means of implementation and a strong bond with international drug agencies. This policy emerged in the 1980s and 1990s and has remained the unchallenged norm until today. The political processes underlying Nigerian drug policy also explain why policy reform has been and will be difficult to accomplish. These domestic political processes have largely been ignored in the existing depictions of drugs in West Africa, as they have mainly focused on externally driven drug threats and foreign policy responses. Most importantly, they have ignored the role played by the state. Rather

  6. Mexico's "ley de narcomenudeo" drug policy reform and the international drug control regime.

    It has been over half a century since the landmark Single Convention on Narcotic Drugs was adopted, for the first time unifying international drug policy under a single treaty aimed at limiting use, manufacture, trade, possession, and trafficking of opiates, cannabis, and other narcotics. Since then, other international drug policy measures have been adopted, largely emphasizing enforcement-based approaches to reducing drug supply and use. Recently, in response to concerns that the historic focus on criminalization and enforcement has had limited effectiveness, international drug policies have begun to undergo a paradigm shift as countries seek to enact their own reforms to partially depenalize or deregulate personal drug use and possession. This includes Mexico, which in 2009 enacted national drug policy reform partially decriminalizing possession of small quantities of narcotics for personal consumption while also requiring drug treatment for repeat offenders. As countries move forward with their own reform models, critical assessment of their legal compatibility and effectiveness is necessary. In this commentary we conduct a critical assessment of the compatibility of Mexico's reform policy to the international drug policy regime and describe its role in the current evolving drug policy environment. We argue that Mexico's reform is consistent with flexibilities allowed under international drug treaty instruments and related commentaries. We also advocate that drug policy reforms and future governance efforts should be based on empirical evidence, emphasize harm reduction practices, and integrate evidence-based evaluation and implementation of drug reform measures.

  7. Drug policy constellations: A Habermasian approach for understanding English drug policy.

    2018-07-01

    It is increasingly accepted that a view of policy as a rational process of fitting evidence-based means to rationally justified ends is inadequate for understanding the actual processes of drug policy making. We aim to provide a better description and explanation of recent English drug policy decisions. We develop the policy constellation concept from the work of Habermas, in dialogue with data from two contemporary debates in English policy; on decriminalisation of drug possession and on recovery in drug treatment. We collect data on these debates through long-term participant observation, stakeholder interviews (n = 15) and documentary analysis. We show the importance of social asymmetries in power in enabling structurally advantaged groups to achieve the institutionalisation of their moral preferences as well as the reproduction of their social and economic power through the deployment of policies that reflect their material interests and normative beliefs. The most influential actors in English drug policy come together in a 'medico-penal constellation', in which the aims and practices of public health and social control overlap. Formal decriminalisation of possession has not occurred, despite the efforts of members of a challenging constellation which supports it. Recovery was put forward as the aim of drug treatment by members of a more powerfully connected constellation. It has been absorbed into the practice of 'recovery-oriented' drug treatment in a way that maintains the power of public health professionals to determine the form of treatment. Actors who share interests and norms come together in policy constellations. Strategic action within and between constellations creates policies that may not take the form that was intended by any individual actor. These policies do not result from purely rational deliberation, but are produced through 'systematically distorted communication'. They enable the most structurally favoured actors to institutionalise

    This commentary addresses some of the challenges posed by the broader normative, legal and policy framework of the United Nations for the international drug control system. The 'purposes and principles' of the United Nations are presented and set against the threat based rhetoric of the drug control system and the negative consequences of that system. Some of the challenges posed by human rights law and norms to the international drug control system are also described, and the need for an impact assessment of the current system alongside alternative policy options is highlighted as a necessary consequence of these analyses.

    Executive summary In September 2015, the member states of the United Nations endorsed sustainable development goals (SDG) for 2030 that aspire to human rights-centered approaches to ensuring the health and well-being of all people. The SDGs embody both the UN Charter values of rights and justice for all and the responsibility of states to rely on the best scientific evidence as they seek to better humankind. In April 2016, these same states will consider control of illicit drugs, an area of social policy that has been fraught with controversy, seen as inconsistent with human rights norms, and for which scientific evidence and public health approaches have arguably played too limited a role. The previous UN General Assembly Special Session (UNGASS) on drugs in 1998 – convened under the theme “a drug-free world, we can do it!” – endorsed drug control policies based on the goal of prohibiting all use, possession, production, and trafficking of illicit drugs. This goal is enshrined in national law in many countries. In pronouncing drugs a “grave threat to the health and well-being of all mankind,” the 1998 UNGASS echoed the foundational 1961 convention of the international drug control regime, which justified eliminating the “evil” of drugs in the name of “the health and welfare of mankind.” But neither of these international agreements refers to the ways in which pursuing drug prohibition itself might affect public health. The “war on drugs” and “zero-tolerance” policies that grew out of the prohibitionist consensus are now being challenged on multiple fronts, including their health, human rights, and development impact. The Johns Hopkins – Lancet Commission on Drug Policy and Health has sought to examine the emerging scientific evidence on public health issues arising from drug control policy and to inform and encourage a central focus on public health evidence and outcomes in drug policy debates, such as the important deliberations of

    The use of antimalarial drugs in India has evolved since the introduction of quinine in the 17 th century. Since the formal establishment of a malaria control programme in 1953, shortly after independence, treatments provided by the public sector ranged from chloroquine, the mainstay drug for many decades, to the newer, recently introduced artemisinin based combination therapy. The complexity of considerations in antimalarial treatment led to the formulation of a National Antimalarial Drug Policy to guide procurement as well as communicate best practices to both public and private healthcare providers. Challenges addressed in the policy include the use of presumptive treatment, the introduction of alternate treatments for drug-resistant malaria, the duration of primaquine therapy to prevent relapses of vivax malaria, the treatment of malaria in pregnancy, and the choice of drugs for chemoprophylaxis. While data on antimalarial drug resistance and both public and private sector treatment practices have been recently reviewed, the policy process of setting national standards has not. In this perspective on antimalarial drug policy, this review highlights its relevant history, analyzes the current policy, and examines future directions.

    2017-03-01

    The efficacy of low- and middle-income countries’ (LMIC) national drug policies in managing antiretroviral (ARV) pharmaceutical prices is not well understood. Though ARV drug prices have been declining in LMIC over the past decade, little research has been done on the role of their national drug policies. This study aims to (i) analyse global ARV prices from 2004 to 2013 and (ii) examine the relationship of national drug policies to ARV prices. Analysis of ARV drug prices utilized data from the Global Price Reporting Mechanism from the World Health Organization (WHO). Ten of the most common ARV drugs (first-line and second-line) were selected. National drug policies were also assessed for 12 countries in the South African Development Community (SADC), which self-reported their policies through WHO surveys. The best predictor of ARV drug price was generic status—the generic versions of 8 out of 10 ARV drugs were priced lower than branded versions. However, other factors such as transaction volume, HIV prevalence, national drug policies and PEPFAR/CHAI involvement were either not associated with ARV drug price or were not consistent predictors of price across different ARV drugs. In the context of emerging international trade agreements, which aim to strengthen patent protections internationally and potentially delay the sale of generic drugs in LMIC, this study shines a spotlight on the importance of generic drugs in controlling ARV prices. Further research is needed to understand the impact of national drug policies on ARV prices.

    2007-12-01

    Illicit drug policy has long been an area that has attracted international policy intervention, however, the European Union has declared it an area of subsidiarity, leaving ultimate control to national governments. Nevertheless, European Union preoccupation with the illicit drug issue and international drug trafficking and organised crime concerns have ensured that continued and increased cooperation in illicit drug policy is never off the agenda. This article examines the history of European integration in contrasting areas of policy and considers both the desirability and the viability of an increasingly harmonised drug policy for Europe. Finally, it proposes a model of integrated illicit drug policy that is strongly connected to developing patterns of European social policy, calling on multi-level governance and close involvement at the level of the citizen.

    Explaining policy change is one of the central tasks of contemporary policy analysis. In this article, we examine the changes in infection control policies for multi-drug resistant tuberculosis (MDR-TB) in South Africa from the time the country made the transition to democracy in 1994, until 2015. We focus on MDR-TB infection control and refer to decentralised management as a form of infection control. Using Kingdon's theoretical framework of policy streams, we explore the temporal ordering of policy framework changes. We also consider the role of research in motivating policy changes. Policy documents addressing MDR-TB in South Africa over the period 1994 to 2014 were extracted. Literature on MDR-TB infection control in South Africa was extracted from PubMed using key search terms. The documents were analysed to identify the changes that occurred and the factors driving them. During the period under study, five different policy frameworks were implemented. The policies were meant to address the overwhelming challenge of MDR-TB in South Africa, contextualised by high prevalence of HIV infection, that threatened to undermine public health programmes and the success of antiretroviral therapy rollouts. Policy changes in MDR-TB infection control were supported by research evidence and driven by the high incidence and complexity of the disease, increasing levels of dissatisfaction among patients, challenges of physical, human and financial resources in public hospitals, and the ideologies of the political leadership. Activists and people living with HIV played an important role in highlighting the importance of MDR-TB as well as exerting pressure on policymakers, while the mass media drew public attention to infection control as both a cause of and a solution to MDR-TB. The critical factors for policy change for infection control of MDR-TB in South Africa were rooted in the socioeconomic and political environment, were supported by extensive research, and can be framed

Notable progress made inthe domain of Public Health, combined with a general increase in the standard of living, has had a direct impact on thediscovery of new drugs and cures and has shifted pharmaceutical policies further in line with the current needs of boththe country’s health system and, its population.Aim: This research aims to both shed light on and analyse the current state of pharmaceutical policy in Cyprus, as well asto try to seek out its weaknesses, making suggestions, where possible, as to how to keep these to the minimum.Results, and Conclusions: The lack of both high level research and major industrial facilities relating to the discovery ofnew pharmaceutical drugs in Cyprus, has hindered the effectiveness of pharmaceutical policy in general domains such ascontrol over the circulation and production of pharmaceutical products in the country, their pricing and distribution andthe monitoring of our drug supplies. The lack of transparency in a number of pharmaceutical procedures, and ofinformation on drugs does not enhance the industry’s reliability, but rather exacerbates an underlying feeling of insecurityrelating to it among the population.

  7. Representations of women and drug use in policy: A critical policy analysis.

    Thomas, Natalie; Bull, Melissa

    2018-06-01

    Contemporary research in the drugs field has demonstrated a number of gender differences in patterns and experiences of substance use, and the design and provision of gender-responsive interventions has been identified as an important policy issue. Consequently, whether and how domestic drug policies attend to women and gender issues is an important question for investigation. This article presents a policy audit and critical analysis of Australian national and state and territory policy documents. It identifies and discusses two key styles of problematisation of women's drug use in policy: 1) drug use and its effect on women's reproductive role (including a focus on pregnant women and women who are mothers), and 2) drug use and its relationship to women's vulnerability to harm (including violent and sexual victimisation, trauma, and mental health issues). Whilst these are important areas for policy to address, we argue that such representations of women who use drugs tend to reinforce particular understandings of women and drug use, while at the same time contributing to areas of 'policy silence' or neglect. In particular, the policy documents analysed are largely silent about the harm reduction needs of all women, as well as the needs of women who are not mothers, young women, older women, transwomen or other women deemed to be outside of dominant normative reproductive discourse. This analysis is important because understanding how women's drug use is problematised and identifying areas of policy silence provides a foundation for redressing gaps in policy, and for assessing the likely effectiveness of current and future policy approaches.

    The goal of seeking to understand the development over time of drug policies is a specific version of the more general intellectual project of finding ways of explaining social change. The latter has been a preoccupation of some of the greatest thinkers within the social sciences of the last 200 years, from Foucault all the way back to the three nineteenth-century pioneers, Marx, Durkheim and Weber. I describe this body of work as 'historical sociology'. In this paper, I outline how a particular approach to historical sociology can be fruitfully drawn upon to understand the development of drug policy, using by way of illustration the example of the analysis of a recent transformation in British drug policy: the rise of the criminal justice agenda. I conclude by arguing that by looking at developments in drug policy in this way, some new insights are opened up. Copyright © 2011 Elsevier B.V. All rights reserved.

  10. Spread of anti-malarial drug resistance: Mathematical model with implications for ACT drug policies

    Directory of Open Access Journals (Sweden)

    Dondorp Arjen M

    2008-11-01

    Full Text Available Abstract Background Most malaria-endemic countries are implementing a change in anti-malarial drug policy to artemisinin-based combination therapy (ACT. The impact of different drug choices and implementation strategies is uncertain. Data from many epidemiological studies in different levels of malaria endemicity and in areas with the highest prevalence of drug resistance like borders of Thailand are certainly valuable. Formulating an appropriate dynamic data-driven model is a powerful predictive tool for exploring the impact of these strategies quantitatively. Methods A comprehensive model was constructed incorporating important epidemiological and biological factors of human, mosquito, parasite and treatment. The iterative process of developing the model, identifying data needed, and parameterization has been taken to strongly link the model to the empirical evidence. The model provides quantitative measures of outcomes, such as malaria prevalence/incidence and treatment failure, and illustrates the spread of resistance in low and high transmission settings. The model was used to evaluate different anti-malarial policy options focusing on ACT deployment. Results The model predicts robustly that in low transmission settings drug resistance spreads faster than in high transmission settings, and treatment failure is the main force driving the spread of drug resistance. In low transmission settings, ACT slows the spread of drug resistance to a partner drug, especially at high coverage rates. This effect decreases exponentially with increasing delay in deploying the ACT and decreasing rates of coverage. In the high transmission settings, however, drug resistance is driven by the proportion of the human population with a residual drug level, which gives resistant parasites some survival advantage. The spread of drug resistance could be slowed down by controlling presumptive drug use and avoiding the use of combination therapies containing drugs with

    Brazil is a country of continental dimensions that, over the last 3 decades, has been making increased efforts to develop effective public policies for controlling the use of both licit and illicit psychoactive substances. In the case of licit drugs, Brazil was a pioneer in following the guidance of the World Health Organization for tobacco control and has witnessed surprising results relating to reduction of smoking prevalence and correlated morbidity and mortality. Today, Brazil has a national structure for organizing, applying, and monitoring laws relating to tobacco. However, in the field of illicit drugs, with crack consumption as a paradigm, the situation is the opposite: its use has been increasing year by year and is being consumed at increasingly young ages and by all social classes. Thus, it is becoming an enormous challenge for public policies relating to prevention and treatment. In this context, the aim of this article is to present a review of the epidemiological data relating to tobacco and crack use in Brazil, with an analysis on the impact of public policies for controlling consumption over recent years. Despite the efforts made over the last 3 decades, Brazil still has a long way to go in order to construct a consistent and effective national drugs policy.

    The control of drug activity currently favors supply-side policies: drug suppliers in the U.S. face a higher arrest rate and longer sentences than demanders. We construct a simple model of drug activity with search and entry frictions in labor and drug markets. Our calibration analysis suggests a strong “dealer replacement effect.” As a result, given a variety of community objectives, it is beneficial to lower supplier arrests and raise the demand arrest rate from current values. A 10% shift from supply-side to demand-side arrests can reduce the population of potential drug dealers by 22–25,000 and raise aggregate local income by $380–400 million, at 2002 prices.

    2017-05-01

    In deliberations on drug policy in United Nations fora, a consensus has emerged that drug use and drug dependence should be treated primarily as public health concerns rather than as crimes. But what some member states mean by "public health approach" merits scrutiny. Some governments that espouse treating people who use drugs as "patients, not criminals" still subject them to prison-like detention in the name of drug-dependence treatment or otherwise do not take measures to provide scientifically sound treatment and humane social support to those who need them. Even drug treatment courts, which the U.S. and other countries hold up as examples of a public health approach to drug dependence, can serve rather to tighten the hold of the criminal justice sector on concerns that should be addressed in the health sector. The political popularity of demonisation of drugs and visibly repressive approaches is an obvious challenge to leadership for truly health-oriented drug control. This commentary offers some thoughts for judging whether a public health approach is worthy of the name and cautions drug policy reformers not to rely on facile commitments to health approaches that are largely rhetorical or that mask policies and activities not in keeping with good public health practise.

  14. Drug Policy and Indigenous Peoples.

    Burger, Julian; Kapron, Mary

    2017-06-01

    This paper identifies the principal concerns of indigenous peoples with regard to current international treaties on certain psychoactive substances and policies to control and eradicate their production, trafficking, and sale. Indigenous peoples have a specific interest in the issue since their traditional lands have become integrated over time into the large-scale production of coca, opium poppy, and cannabis crops, in response to high demand from the American and European markets, among others. As a consequence, indigenous peoples are persecuted because of their traditional use of these and other plant-based narcotics and hallucinogens. They are also victims of the drug producers who remove them from their lands or forcibly recruit them into the production process. As indigenous peoples are caught in the violent world of illicit drug production, law enforcement often targets them first, resulting in disproportionate rates of criminalization and incarceration.

  15. What is good governance in the context of drug policy?

    2014-09-01

    The concept of governance is applied in a wide range of contexts, but this paper focuses on governance in relation to public administration, i.e. states and how they take action, and specifically governance of particular policy areas. In the current context of financial austerity and an era of globalisation, policy-makers face pressures and challenges from a growing range of interests and local, national and supranational actors. Drug policy is an example of a particularly contentious and polarised area in which governance-related challenges abound. In response to these challenges, interest has grown in developing agreed policy governance standards and processes and articulating policy-making guidelines, including the use of available evidence to inform policy-making. Attempts have been made to identify 'policy fundamentals' - factors or aspects of policy-making apparently associated with successful policy development and implementation (Hallsworth & Rutter, 2011; Laughrin, 2011) and, in the drug policy field, Hughes et al. (2010) reflecting on the co-ordination of Australian drug policy highlighted some of what they considered principles of good governance. But how useful is the concept of 'good governance'; how well can it be defined, and to what purpose? As part of a wider project considering the governance of drug policy, RAND Europe and the UK Drug Policy Commission undertook a targeted review of other research and sought expert views, from within and beyond drug policy, on principles, processes, structures and stakeholders associated with good drug policy governance. From this emerged some perceived characteristics of good governance that were then used by the UK Drug Policy Commission to assess the extent to which drug policy making in the UK fits with these perceived good governance characteristics, and to suggest possible improvements. Particular consideration was given to the range of interests at stake, the overarching aims of drug policy and the

  16. Drug policy, harm and human rights: a rationalist approach.

    Stevens, Alex

    2011-05-01

    It has recently been argued that drug-related harms cannot be compared, so making it impossible to choose rationally between various drug policy options. Attempts to apply international human rights law to this area are valid, but have found it difficult to overcome the problems in applying codified human rights to issues of drug policy. This article applies the rationalist ethical argument of Gewirth (1978) to this issue. It outlines his argument to the 'principle of generic consistency' and the hierarchy of basic, nonsubtractive and additive rights that it entails. It then applies these ideas to drug policy issues, such as whether there is a right to use drugs, whether the rights of drug 'addicts' can be limited, and how different harms can be compared in choosing between policies. There is an additive right to use drugs, but only insofar as this right does not conflict with the basic and nonsubtractive rights of others. People whose freedom to choose whether to use drugs is compromised by compulsion have a right to receive treatment. They retain enforceable duties not to inflict harms on others. Policies which reduce harms to basic and nonsubtractive rights should be pursued, even if they lead to harms to additive rights. There exists a sound, rational, extra-legal basis for the discussion of drug policy and related harms which enables commensurable discussion of drug policy options. Copyright © 2011 Elsevier B.V.

    2005-01-01

    Essential drug lists and generic drug policies have been promoted as strategies to improve access to pharmaceuticals and control their rapidly escalating costs. This article reports the results of a preliminary survey conducted in 10 Latin American countries. The study aimed to document the experiences of different countries in defining and implementing generic drug policies, determine the cost of registering different types of pharmaceutical products and the time needed to register them, and uncover the incentives governments have developed to promote the use of multisource drugs. The survey instrument was administered in person in Chile, Ecuador and Peru and by email in Argentina, Brazil, Bolivia, Colombia, Costa Rica, Nicaragua and Uruguay. There was a total of 22 respondents. Survey responses indicated that countries use the terms generic and bioequivalence differently. We suggest there is a need to harmonize definitions and technical concepts. PMID:15682251

  19. Multiple drug cost containment policies in Michigan's Medicaid program saved money overall, although some increased costs.

    Science.gov (United States)

    Kibicho, Jennifer; Pinkerton, Steven D

    2012-04-01

    Michigan's Medicaid program implemented four cost containment policies--preferred drug lists, joint and multistate purchasing arrangements, and maximum allowable cost--during 2002-04. The goal was to control growth of drug spending for beneficiaries who were enrolled in both Medicaid and Medicare and taking antihypertensive or antihyperlipidemic prescription drugs. We analyzed the impact of each policy while holding the effect of all other policies constant. Preferred drug lists increased both preferred and generic drugs' market share and reduced daily cost--the cost per day for each prescription provided to a beneficiary. In contrast, the maximum allowable cost policy increased daily cost and was the only policy that did not generate cost savings. The joint and multistate arrangements did not affect daily cost. Despite these policy trade-offs, the cumulative effect was a 10 percent decrease in daily cost and a total cost savings of $46,195 per year. Our findings suggest that policy makers need to evaluate the impact of multiple policies aimed at restraining drug spending, and further evaluate the policy trade-offs, to ensure that scarce public dollars achieve the greatest return for money spent.

  1. Colombian drugs policy. The dose for personal and health rights

    2013-07-01

    Full Text Available This article is a review of Colombian law on drugs, with special emphasis on the so-called dose for personal and health rights that relate to the use of legal or illegal drugs. A brief contextualization of international treaties on drugs is presented, as well as presenting some cases representing the current debate on trade control measures and use of illegal drugs. The article argues that in the international and Colombian debate there are no homogeneous positions, and the repressive policies towards illegal drug use coexist with approaches from the public health that point to the recognition of the rights of people who use legal or illegal substances.

    Bulgaria has a mixed public-private health care financing system. Health care is financed mainly from compulsory health insurance contributions and out-of-pocket payments. Out-of-pocket payments constitute a large share of the total health care expenditure (44.14% in 2014). The share of drugs expenditure for outpatient treatment was 42.3% of the total health care expenditure in 2014, covered mainly by private payments (78.6% of the total pharmaceutical expenditure). The drug policy is run by the Ministry of Health (MoH), the National Council on Prices and Reimbursement of Medicinal Products, and the Health Technology Assessment Commission. The MoH defines diseases for which the National Health Insurance Fund (NHIF) pays for medicines. The National Council on Prices and Reimbursement of Medicinal Products maintains a positive drug list (PDL) and sets drug prices. Health technology assessment was introduced in 2015 for medicinal products belonging to a new international nonproprietary name group. The PDL defines prescription medicines that are paid for by the NHIF, the MoH, and the health care establishments; exact patient co-payments and reimbursement levels; as well as the ceiling prices for drugs not covered by the NHIF, including over-the-counter medicines. The reimbursement level can be 100%, 75%, or up to 50%. The PDL is revised monthly in all cases except for price increase. Physicians are not assigned with pharmaceutical budgets, there is a brand prescribing practice, and the substitution of prescribed medicines by pharmacists is prohibited. Policies toward cost containment and effectiveness increase include introduction of a reference pricing system, obligation to the NHIF to conduct mandatory centralized bargaining of discounts for medicinal products included in the PDL, public tendering for medicines for hospital treatment, reduction of markup margins of wholesalers and retailers, patient co-payment, and the introduction of health technology assessment

    This article examines the processes by which the Anabolic Steroid Control Act of 2004, an act that added steroid precursors such as androstenedione to the list of Schedule III Controlled Substances in the United States, came to pass in both the House of Representatives and the Senate. Grounded theoretically in political economy, the article addresses, in the abstract, how the interplay of political pressures and economic influences stands to affect the actions of public officials, and how "tougher" drug policies-those touted to be more substantive and efficacious than existing regulations-often fail to effect change. The article concludes with implications for those involved in the regulation of anabolic steroids and steroid precursors.

    In recent decades a range of advocacy organisations have emerged on the drugs policy landscape seeking to shape the development of policy at national and international levels. This development has been facilitated by the expansion of 'democratic spaces' for civil society participation in governance fora at national and supranational level. However, little is known about these policy actors - their aims, scope, organisational structure, or the purpose of their engagement. Drug policy advocacy organisations were defined as organisations with a clearly stated aim to influence policy and which were based in Europe. Data on these organisations was collected through a systematic tri-lingual (English, French and Spanish) Internet search, supplemented by information provided by national agencies in the 28 EU member states, Norway and Turkey. In order to differentiate between the diverse range of activities, strategies and standpoints of these groups, information from the websites was used to categorise the organisations by their scope of operation, advocacy tools and policy constituencies; and by three key typologies - the type of advocacy they engaged in, their organisational type, and their advocacy objectives and orientation. The study identified over two hundred EU-based advocacy organisations (N=218) which included civil society associations, NGOs, and large-scale alliances and coalitions, operating at local, national and European levels. Three forms of advocacy emerged from the data analysis - peer, professional and public policy. These groups focused their campaigns on practice development (harm reduction or abstinence) and legislative reform (reducing or strengthening drug controls). The findings from this study provide a nuanced profile of civil society advocacy as a policy community in the drugs field; their legitimacy to represent cases, causes, social values and ideals; and their focus on both insider and outsider strategies to achieve their goals.

The results show policies cen...

  7. Illicit drugs policy through the lens of regulation.

    Science.gov (United States)

    Ritter, Alison

    2010-07-01

    The application of regulatory theory to the problem of illicit drugs has generally been thought about only in terms of 'command and control'. The international treaties governing global illicit drug control and the use of law enforcement to dissuade and punish offenders have been primary strategies. In this paper I explore the application of other aspects of regulatory theory to illicit drugs-primarily self-regulation and market regulation. There has been an overreliance on strategies from the top of the regulatory pyramid. Two other regulatory strategies--self-regulation and market regulation--can be applied to illicit drugs. Self-regulation, driven by the proactive support of consumer groups may reduce drug-related harms. Market strategies such as pill-testing can change consumer preferences and encourage alternate seller behaviour. Regulatory theory is also concerned with partnerships between the state and third parties: strategies in these areas include partnerships between police and pharmacies regarding sale of potential precursor chemicals. Regulatory theory and practice is a rich and well-developed field in the social sciences. I argue that governments should consider the full array of regulatory strategies. Using regulatory theory provides a rationale and justification to strategies that are currently at the whim of politics, such as funding for user groups. The greater application of regulatory approaches may produce more flexible and structured illicit drug policies. Copyright (c) 2009 Elsevier B.V. All rights reserved.

  8. 'Worth the test?' Pragmatism, pill testing and drug policy in Australia.

    Science.gov (United States)

    Groves, Andrew

    2018-04-10

    Recent deaths of young Australian music festival attendees from 'party-drug' overdoses have sparked debate about the effectiveness of drug policies. Australia is widely lauded for its harm minimisation approach to drugs, and yet, over the last 30 years, it can be argued its policies have been fragmented, sometimes inconsistent and contradictory. The present article examines the root of this inconsistency, using it as a foundation to advocate for drug policy reform. In keeping with the goals of the National Drug Strategy to promote policy innovation, there is an opportunity to learn from international studies which have shown promising findings in the reduction of party-drug use and its harms through application of pill testing. This paper evaluates Australia's National Drug Strategy and pill testing through a lens of pragmatism, to determine whether there is space for testing practices in contemporary policy. Specifically, the paper analyses current drug policy literature and research studies, examining a range of key drug use indicators, social and political debate and research evidence. The need for policy reform, attitudinal and cultural shifts and development of stronger cross-sectoral partnerships is highlighted, to ensure a rational and logical approach that genuinely tackles drug policy-making and strategy from a broad public health perspective. Using a theoretical frame of pragmatism and drawing from national and international research evidence, this paper recommends the integration of pill testing into Australia's harm minimisation strategy.

  9. Improving drug policy: The potential of broader democratic participation.

    Science.gov (United States)

    Ritter, Alison; Lancaster, Kari; Diprose, Rosalyn

    2018-05-01

    Policies concerned with illicit drugs vex governments. While the 'evidence-based policy' paradigm argues that governments should be informed by 'what works', in practice policy makers rarely operate this way. Moreover the evidence-based policy paradigm fails to account for democratic participatory processes, particularly how community members and people who use drugs might be included. The aim of this paper is to explore the political science thinking about democratic participation and the potential afforded in 'deliberative democracy' approaches, such as Citizens Juries and other mini-publics for improved drug policy processes. Deliberative democracy, through its focus on inclusion, equality and reasoned discussion, shows potential for drug policy reform and shifts the focus from reliance on and privileging of experts and scientific evidence. But the very nature of this kind of 'deliberation' may delimit participation, notably through its insistence on authorised modes of communication. Other forms of participation beyond reasoned deliberation aligned with the ontological view that participatory processes themselves are constitutive of subject positions and policy problems, may generate opportunities for considering how the deleterious effects of authorised modes of communication might be overcome.

  10. Making drug policy together: reflections on evidence, engagement and participation.

    Science.gov (United States)

    Roberts, Marcus

    2014-09-01

    This commentary considers the relationship between evidence, engagement and participation in drug policy governance. It argues that the use of various forms of evidence (for example, statistical data and service user narratives) is critical for meaningful stakeholder engagement and public participation in drug policy, as well as effective policy design and implementation. The respective roles of these different kinds of evidence in consultation processes need to be better understood. It discusses the limits of evidence, which it suggests is rarely conclusive or decisive for drug policy. This is partly because of the incompleteness of most research agendas and the lack of consensus among researchers, but also because issues in drug policy are inherently contestable, involving considerations that lie outside the competency of drug policy specialist as such. In particular, this is because they involve normative and evaluative issues that are properly political (for example, about the relative weight to be accorded to different kinds of harm and benefit). It concludes by supporting calls for a more nuanced understanding of the relationship between evidence, engagement and politics than is implicit in the term 'evidence based policy'. It also argues that we should view the inherent contestability of drug policy not as something that can or should be resolved by 'objective' evidence, but as a source of vitality and creativity in policy development and evaluation.

    While the impact of changing drug policies on rates of drug use has been investigated, research into how help-seeking behaviour changes as drug policies become more public-health focused is limited. This paper investigates reported changes in confidence to utilise drug services following hypothetical changes in national drug policy among a sample of individuals who report recent illicit drug use. We predict that liberalising national drug policy will increase the propensity for people who take illegal drugs to utilise health services. The data were drawn from a sample of self-reported responses to the 2014 Global Drug Survey. Respondents were asked if they would be more confident seeking help if each of the following policy changes were made in their country; a) drugs were legalised; b) penalties for possession of small amounts of drugs were reduced to a fine only; c) drugs were legally available through governments outlets. Multiple correspondence analysis and multinomial logistic regression with post-estimation linear hypothesis testing were conducted. Individuals residing in countries with relatively liberal drug policy regimes report their help-seeking behaviour is unlikely to change given the hypothetical policy amendments. Individuals from countries with prohibition-based drug policies reported a far greater propensity for changing their help-seeking behaviour in the event of hypothetical policy amendments, citing reduced fear of criminal sanctions as the major reason. Age and sex differences were also found. The current study demonstrates the capacity for national drug policy reform to influence drug use risk by facilitating or impeding health service engagement among individuals who use illicit substances. We suggest national drug policy requires careful consideration of both prevention goals and the needs of individuals already engaged in illicit substance use; more liberal drug policies may actually encourage the adoption of harm reduction strategies such

    2011-11-01

    From the mid-1990s, UK governments developed partnerships to tackle drugs nationally and locally. Over time, increased resources focused on communities and localities in greatest need. This reflected growing awareness of the concentration of problems in deprived areas, with social and spatial segregation being a feature of post-industrial urban areas. A review of English drug policy since the 1990s, drawing on:- analysis of documents; a review of sociological studies; an illustrative case-study of one northern town; interviews with local policy players; statistical analysis of key indicators with some of these data presented using Geographical Information System (GIS) mapping. In-depth sociological studies demonstrate interconnections between historical patterns, socio-economic change, cultural complexity, deprivation, limited opportunities and illicit drugs. At local level, there are links between concentrated multiple deprivation, poor health, acquisitive crime and problematic drug use. Partnership policies, encouraged by the provision of ring-fenced funds, have been effective in containing problems. Underlying issues of inequality are however neglected in political debates. The article argues that post-industrial towns and cities are characterised by an increase in problems related to poverty and drugs. Both the real shape and perceptions of what is the problem change over time. In England, the profile of the problem drug user was described in a number of sociological studies conducted from the 1980s onwards. Key features were the concentration of problems in certain social groups (such as the poorly educated or unemployed) and in certain areas (inner cities or outer estates). Responding to rising public concern, national drug strategies developed and the New Labour Government after 1997 prioritised the issue of drugs, directing increased resources to drug treatment with tight control over the use of these new monies through target setting and measurement of

    Significant research attention has been given to understanding the processes of drug policy reform. However, there has been surprisingly little analysis of the persistence of policy in the face of opposition and evidence of ineffectiveness. In this article we analysed just such a case - police drug detection dog policy in NSW, Australia. We sought to identify factors which may account for the continuation of this policy, in spite of counter-evidence and concerted advocacy. The analysis was conducted using the Advocacy Coalition Framework (ACF). We collated documents relating to NSW drug detection dog policy from 1995 to 2016, including parliamentary records (NSW Parliament Hansard), government and institutional reports, legislation, police procedures, books, media, and academic publications. Texts were then read, coded and classified against the core dimensions of the ACF, including subsystem actors and coalitions, their belief systems and resources and venues employed for policy debate. Three coalitions were identified as competing in the policy subsystem: security/law and order, civil liberties and harm reduction. Factors that aided policy stability were the continued dominance of the security/law and order coalition since they introduced the drug dog policy; a power imbalance enabling the ruling coalition to limit when and where the policy was discussed; and a highly adversarial policy subsystem. In this context even technical knowledge that dogs infringed civil liberties and increased risks of overdose were readily downplayed, leading to only incremental changes in implementation rather than policy cessation or wholesale revision. The analysis provides new insights into why the accumulation of new evidence and advocacy efforts can be insufficient to drive significant policy change. It poses a challenge for the evidence-based paradigm suggesting that in highly adversarial policy subsystems new evidence is unlikely to generate policy change without broader

    2018-02-01

    The international community's commitment to halve by 2015 the HIV transmission among people who inject drugs has not only been largely missed, instead new HIV infections have increased by 30%. Moreover, drug injection remains one of the drivers of new HIV infections due to punitive responses and lack of harm reduction resourcing. In the midst of this situation, adolescents are a forgotten component of the global response to illegal drugs and their link with HIV infection. The Sustainable Development Goals (SDGs) present an opportunity to achieve the global objective of ending AIDS among adolescents who use drugs, by addressing the structural vulnerabilities they face be they economic, social, criminal, health-related or environmental. The implementation of the SDGs presents an opportunity to address the horizontal nature of drug policy and to efficiently address the drugs-adolescents-HIV risk nexus. Adolescent-focused drug policies are linked to goals 1, 3, 4, 10, 16 and 17. Goals 3 and 16 are the most relevant; the targets of the latter link to the criminalization of drug use and punitive policy environments and their impact on adolescents' health and HIV transmission risks. Moreover, it presents an opportunity to include adolescent needs that are missing in the three drug control conventions (1961, 1971 and 1988), and link them with the provisions of the Convention on the Rights of the Child (1989). Finally, the six principles to deliver on sustainable development are also an opportunity to divert adolescents who use drugs away from criminalization and punitive environments in which their vulnerability to HIV is greater. Addressing HIV among adolescents who use drugs is an extremely complex policy issue depending on different sets of binding and non-binding commitments, interventions and stakeholders. The complexity requires a horizontal response provided by the SDGs framework, starting with the collection of disaggregated data on this specific subgroup. Ending

  15. Drug policy in sport: hidden assumptions and inherent contradictions.

    Science.gov (United States)

    Smith, Aaron C T; Stewart, Bob

    2008-03-01

    This paper considers the assumptions underpinning the current drugs-in-sport policy arrangements. We examine the assumptions and contradictions inherent in the policy approach, paying particular attention to the evidence that supports different policy arrangements. We find that the current anti-doping policy of the World Anti-Doping Agency (WADA) contains inconsistencies and ambiguities. WADA's policy position is predicated upon four fundamental principles; first, the need for sport to set a good example; secondly, the necessity of ensuring a level playing field; thirdly, the responsibility to protect the health of athletes; and fourthly, the importance of preserving the integrity of sport. A review of the evidence, however, suggests that sport is a problematic institution when it comes to setting a good example for the rest of society. Neither is it clear that sport has an inherent or essential integrity that can only be sustained through regulation. Furthermore, it is doubtful that WADA's anti-doping policy is effective in maintaining a level playing field, or is the best means of protecting the health of athletes. The WADA anti-doping policy is based too heavily on principals of minimising drug use, and gives insufficient weight to the minimisation of drug-related harms. As a result drug-related harms are being poorly managed in sport. We argue that anti-doping policy in sport would benefit from placing greater emphasis on a harm minimisation model.

  16. The stages of the international drug control system.

    This paper argues that the history of the international drug control system of the League of Nations/United Nations can be divided into three cumulative stages. The first stage, the supply stage, dates back to early part of the 20th century, and aimed to reduce the supply of drugs through careful monitoring and trade regulations. This has remained the dominant control strategy. In the middle of the century, demand control, in the form of treatment and criminalization of the individual user, began to appear. This was the least successful stage. Finally, in the 1980s, the dangers of the drug traffic assumed an important place on the international agenda and measures to reduce drug-related organized crime were enacted. To date, this has been a process of proliferation of regulatory strategies. Recently, new challenges to the international drug control system have emerged, including well-funded non-governmental organizations critical of the war on drugs, and the adoption of harm reduction measures in national policies around the world.

    A new pricing policy was introduced in Korea in April 2012 with the aim of strengthening competition among off-patent drugs by eliminating price gaps between originators and generics. Examine the effect of newly implemented pricing policy. Retrospectively examining the effects through extracting from the National Health Insurance claims data a 30-month panel dataset (January 2011-June 2013) containing consumption data in four major therapeutic classes (antihypertensives, lipid-lowering drugs, antiulcerants and antidepressants). Proxies for market competition were examined before and after the policy. The new pricing policy did not enhance competition among off-patent drugs. In fact, price dispersion significantly decreased as opposed to the expected change. Originator-to-generic utilization increased 6.12 times (p = 0.000) after the new policy. The new pricing policy made no impact on competition among off-patent drugs. Competition in the off-patent market cannot be enhanced unless both supply and demand side measures are coordinated.

  19. Canadian Drug Policy and the Reproduction of Indigenous Inequities

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Canada’s federal drug policy under the Harper government (2006 to present is “tough on crime” and dismissive of public health and harm reduction approaches to problematic drug use. Drawing on insights from discourse and critical race theories, and Bacchi’s (2009 poststructural policy analysis framework, problematic representations in Canada’s federal drug policy discourse are examined through proposed and passed legislation, government documents, and parliamentary speaker notes. These problem representations are situated within their social, historical, and colonial context to demonstrate how this policy is poised to intersect with persistent racial inequalities that position Indigenous peoples for involvement with illicit substances and markets, and racialized discourses and practices within law and law enforcement that perpetuate Indigenous over-representation in the criminal justice system.

  20. The evolution of Israeli public policy for drug-using backpackers.

    Over the past 20 years, the young-adult backpacking trip has emerged as a significant social phenomenon in Israeli society. This has received attention from scholars specializing in anthropology and tourism research, but only a few analytical studies exist on the drug policy processes and few provide Israeli social and health perspectives. The interaction of policymakers, media, and health deviancy is an important focus of inquiry. This study charts the establishment of a drug policy for Israeli backpackers. It covers the period from the emergence of the problem in the early 1990s until the present. This study employs content analysis of newspaper articles and official documents, protocols, and reports written by policymakers and professionals. The latter were mostly produced by the Israel Anti-Drug Authority (IADA) and the Special Committee on Drug and Alcohol Abuse (SCDAA) in the Israeli Knesset. These are the two major Israeli agencies responsible for drug policy. Three periods in the establishment of backpacker drug policy can be identified. First period - until late 1995: No drug problem was recognized. The subject was not part of the public agenda. Even so, many backpackers were actually taking drugs. Second Period - late 1995 to 2000: The Israeli media started to report intensively on backpacker drug use. The issue then flared up into a significant 'social problem' demanding health and social solutions. In this phase, policymakers capitalized on a window of opportunity, and formulated a policy emphasizing prevention. Third period - from 2001 until the present: A sea change in institutional attitude occurred. In this period, drug-policy emphasis shifted from prevention to therapeutic-treatment approaches. As a result, harm reduction and unique treatment strategies were developed. Policymakers should continue to improve health prevention, treatment, and harm reduction resources. It is recommended that the Ministry of Health set up consultation centers at

  1. Issues surrounding orphan disease and orphan drug policies in Europe.

    An orphan disease is a disease with a very low prevalence. Although there are 5000-7000 orphan diseases, only 50 orphan drugs (i.e. drugs developed to treat orphan diseases) were marketed in the EU by the end of 2008. In 2000, the EU implemented policies specifically designed to stimulate the development of orphan drugs. While decisions on orphan designation and the marketing authorization of orphan drugs are made at the EU level, decisions on drug reimbursement are made at the member state level. The specific features of orphan diseases and orphan drugs make them a high-priority issue for policy makers. The aim of this article is to identify and discuss several issues surrounding orphan disease and drug policies in Europe. The present system of orphan designation allows for drugs for non-orphan diseases to be designated as orphan drugs. The economic factors underlying orphan designation can be questioned in some cases, as a low prevalence of a certain indication does not equal a low return on investment for the drug across its indications. High-quality evidence about the clinical added value of orphan drugs is rarely available at the time of marketing authorization, due to the low number of patients. A balance must be struck between ethical and economic concerns. To this effect, there is a need to initiate a societal dialogue on this issue, to clarify what society wants and accepts in terms of ethical and economic consequences. The growing budgetary impact of orphan drugs puts pressure on drug expenditure. Indications can be extended for an orphan drug and the total prevalence across indications is not considered. Finally, cooperation needs to be fostered in the EU, particularly through a standardized approach to the creation and use of registries. These issues require further attention from researchers, policy makers, health professionals, patients, pharmaceutical companies and other stakeholders with a view to optimizing orphan disease and drug policies in

    While regulatory policy is well defined for orphan drug development in the United States and Europe, rare disease policy in China is still evolving. Many Chinese patients currently pay out of pocket for international treatments that are not yet approved in China. The lack of a clear definition and therefore regulatory approval process for rare diseases has, until now, de-incentivized pharmaceutical companies to pursue rare disease drug development in China. In turn, many grassroots movements have begun to support rare disease patients and facilitate drug discovery through research. Recently, the Chinese FDA set new regulatory guidelines for drugs being developed in China, including an expedited review process for life-saving treatments. In this review, we discuss the effects of these new policy changes on and suggest potential solutions to innovate orphan drug development in China.

  3. Rethinking 'flexibilities' in the international drug control system-Potential, precedents and models for reforms.

    Science.gov (United States)

    Collins, John

    2017-01-24

    Much international drug policy debate centres on, what policies are permissible under the international drug treaties, whether member states are openly 'breaching' these treaties by changing national regulatory frameworks and shifting priorities away from a 'war on drugs' approach, and what 'flexibility' exists for policy reform and experimentation at national and local levels. Orthodox interpretations hold that the current system is a US-led 'prohibition regime' that was constructed in an extremely repressive and restrictive manner with almost no flexibility for significant national deviations. This paper challenges these orthodox interpretive frameworks and suggests no absolute and clear dichotomy between strict adherence and 'breaches' of the international treaties. This paper uses historical analysis to highlight the flaws in orthodox policy analyses, which assume a uniform interpretation, implementation and set of policy trajectories towards a 'prohibition regime' in the 20th century. It challenges some existing legal interpretations of the treaties through recourse to historical precedents of flexible interpretation and policy prioritisation. It then examines the legal justifications currently being formulated by member states to explain a shift towards policies which, until recently, have been viewed as outside the permissible scope of the conventions. It then examines a functionalist framework for understanding the likely contours of drug diplomacy in the post-UN General Assembly Special Session (UNGASS) 2016 era. The paper highlights that, contrary to current policy discourses, the international control system has always been implemented in a 'flexible' manner. It demonstrates that drug control goals were repeatedly subsumed to security, development, political stability and population welfare imperatives, or what we might now refer to under the umbrella of 'development issues.' The paper further demonstrates that policy prioritisation, inherent treaty

    Safety policies in effect on the Hibernia offshore platform in the Hibernia Field, 300 km off the Newfoundland coast, were described, especially with regard to alcohol and drugs. No alcohol of any type is allowed on the platform. Each employee departing for the platform must take a breathalyzer test prior to boarding the helicopter. The tolerance level at the heliport is .05 per cent and anyone exceeding that is not permitted to board the aircraft. Employees must also be drug-free to be permitted to travel offshore. There is a policy of random testing on the platform for illicit or `recreational` drugs. All employees must agree in writing to taking these tests through provision of a urine sample on demand, as a condition of employment. The use of alcohol offshore or the detection of illegal drugs through the random testing program are grounds for dismissal, although team leaders have some discretion to judge each situation on its own set of circumstances. The company also has the right to search individuals, their sleeping quarters, lockers and other property for alcohol, drugs or other controlled substances in situations where reasonable doubt exists. To date there has been very little resistance within Hibernia to its random testing and zero tolerance policies. Employees understand that this is a safety issue and that they serve to protect everyone who works on the offshore platform.

    This alcohol and drug policy model was developed to help employers manage and reduce the risks associated with drug and alcohol use in the workplace. The policy model outlined guidelines for establishing and implementing drug and alcohol policies, and discussed treatment programs and opportunities for re-employment. The model was developed by Enform, the upstream petroleum industry's safety and training arm, who used a previous guide developed by the Construction Owner's Association of Alberta (COAA) as a model. Enform's model provided a summary of key accountabilities across all levels of industry as well as the accepted minimum criteria for developing alcohol and drug policies. The model included guidelines and recommendations for employees, supervisors, and owners, employers, and contractors. The responsibilities of associations, organizations, and private companies were also outlined. An overview of recommended implementation plans was provided, as well as details of alcohol and drug use education programs and workplace rules. A supervisor's guide to implementation provided outlines of the causes of drug use among employees. tabs.

    The National Institute of Public Policy for Alcohol and Other Drugs (INPAD) is based at the Federal University of São Paulo, Brazil, and was created to collect scientific evidence regarding epidemiology, develop new therapeutic approaches, study health economics and provide education to subsidize the proper measures to change the Brazilian scenario of alcohol and drug consumption. Policies directed towards the control of alcohol and drugs in Brazil are fragmented, poorly enforced and therefore ineffective. The unregulated market of alcohol in Brazil has contributed to the worsening health of the Brazilian population. Since 1994, INPAD has participated actively in academic debates and discussions about alcohol and drug policies and their effects on the political welfare of the country. Many scientific papers and books have been published on this subject, and the internet and other media have provided excellent opportunities for the dissemination of specialized information to the general population. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

    This study is an empirical assessment of the impact of the drug decriminalization policy followed by Portugal in July 2001, on the price of illicit drugs. The analysis is performed using a difference-in-differences approach and the Synthetic Control Method in order to construct a synthetic control unit from a convex combination of countries. The results suggest that the prices of opiates and cocaine in the post-treatment period did not decrease in the sequence of the policy change. We conclude that the drug decriminalization policy seems to have caused no harm through lower illicit drugs prices, which would lead to higher drug usage and dependence.

  9. Psychedelics and cognitive liberty: Reimagining drug policy through the prism of human rights.

    Science.gov (United States)

    Walsh, Charlotte

    2016-03-01

    This paper reimagines drug policy--specifically psychedelic drug policy--through the prism of human rights. Challenges to the incumbent prohibitionist paradigm that have been brought from this perspective to date--namely by calling for exemptions from criminalisation on therapeutic or religious grounds--are considered, before the assertion is made that there is a need to go beyond such reified constructs, calling for an end to psychedelic drug prohibitions on the basis of the more fundamental right to cognitive liberty. This central concept is explicated, asserted as being a crucial component of freedom of thought, as enshrined within Article 9 of the European Convention on Human Rights (ECHR). It is argued that the right to cognitive liberty is routinely breached by the existence of the system of drug prohibition in the United Kingdom (UK), as encoded within the Misuse of Drugs Act 1971 (MDA). On this basis, it is proposed that Article 9 could be wielded to challenge the prohibitive system in the courts. This legal argument is supported by a parallel and entwined argument grounded in the political philosophy of classical liberalism: namely, that the state should only deploy the criminal law where an individual's actions demonstrably run a high risk of causing harm to others. Beyond the courts, it is recommended that this liberal, rights-based approach also inform psychedelic drug policy activism, moving past the current predominant focus on harm reduction, towards a prioritization of benefit maximization. How this might translate in to a different regulatory model for psychedelic drugs, a third way, distinct from the traditional criminal and medical systems of control, is tentatively considered. However, given the dominant political climate in the UK--with its move away from rights and towards a more authoritarian drug policy--the possibility that it is only through underground movements that cognitive liberty will be assured in the foreseeable future is

    Rotman, M; Laven, D; Levine, G

    1996-04-01

    The regulatory policy of the Food and Drug Administration (FDA) on radiopharmaceuticals flows from a rigid, traditional, drug-like interpretation of the FDC Act on the licensing of radiopharmaceuticals. This contributes to significant delays in the drug-approval process for radiopharmaceuticals, which are very costly to the nuclear medicine community and the American public. It seems that radiopharmaceuticals would be better characterized as molecular devices. Good generic rule-making principles include: use of a risk/benefit/cost analysis; intent based on sound science; performance standards prepared by outside experts; a definite need shown by the regulatory agency; to live with the consequences of any erroneous cost estimates; and design individual credential requirements so that additional training results in enhanced professional responsibility. When these common elements are applied to current FDA policy, it seems that the agency is out of sync with the stated goals for revitalizing federal regulatory policies as deemed necessary by the Clinton administration. Recent FDA rulings on positron-emission tomography, Patient Package inserts, and on medical device service accentuate the degree of such asynchronization. Radiopharmaceutical review and licensing flexibility could be dramatically improved by excluding radiopharmaceuticals from the drug category and reviewing them as separate entities. This new category would take into account their excellent record of safety and their lack of pharmacological action. Additionally, their evaluation of efficacy should be based on their ability to provide useful scintiphotos, data, or responses of the physiological system it portends to image, quantitate, or describe. To accomplish the goal of transforming the FDA's rigid, prescriptive policy into a streamlined flexible performance-based policy, the Council on Radionuclides and Radiopharmaceuticals proposal has been presented. In addition, it is suggested that the United

    Drug policy, whether for legal or illegal substances, is a controversial field that encompasses many complex issues. Policies can have effects on a myriad of outcomes and stakeholders differ in the outcomes they consider and value, while relevant knowledge on policy effects is dispersed across multiple research disciplines making integrated judgements difficult. Experts on drug harms, addiction, criminology and drug policy were invited to a decision conference to develop a multi-criterion decision analysis (MCDA) model for appraising alternative regulatory regimes. Participants collectively defined regulatory regimes and identified outcome criteria reflecting ethical and normative concerns. For cannabis and alcohol separately, participants evaluated each regulatory regime on each criterion and weighted the criteria to provide summary scores for comparing different regimes. Four generic regulatory regimes were defined: absolute prohibition, decriminalisation, state control and free market. Participants also identified 27 relevant criteria which were organised into seven thematically related clusters. State control was the preferred regime for both alcohol and cannabis. The ranking of the regimes was robust to variations in the criterion-specific weights. The MCDA process allowed the participants to deconstruct complex drug policy issues into a set of simpler judgements that led to consensus about the results. Copyright © 2018 The Authors.

    2005-01-01

    In 1999, the Korean government made a drug pricing policy reform to improve the efficiency and transparency of the drug distribution system. Yet, its policy formation process was far from being rational. Facing harsh resistance from various interest groups, the government changed its details into something different from what was initially investigated and planned. So far, little evidence supports any improvement in Korea's drug distribution system. Instead, the new drug pricing policy has deteriorated Korea's national health insurance budget, indicating a heavier economic burden for the general public. From Korea's experience, we may draw some lessons for the future development of a better health care system. As a society becomes more pluralistic, the government should come out of authoritarianism and thoroughly prepare in advance for resistance to reform, by making greater efforts to persuade strong interest groups while informing the general public of potential benefits of the reform. Additionally, facing developing civic groups, the government should listen but not rely too much on them at the final stage of the policy formation. Many of the civic groups lack expertise to evaluate the details of policy and tend to act in a somewhat emotional way. PMID:15988802

    2016-05-01

    We examined whether access to US-approved orphan drugs in Canada has changed between 1997 (when Canada chose not to adopt an orphan drug policy) and 2012 (when Canada reversed its policy decision). Specifically, we looked at two dimensions of access to US-approved orphan drugs in Canada: (1) regulatory access; and (2) temporal access. Whereas only 63% of US-approved orphan drugs were granted regulatory approval in 1997, we found that regulatory access to US-approved orphan drugs in Canada increased to 74% between 1997 and 2012. However, temporal access to orphan drugs is slower in Canada: in a head-on comparison of 40 matched drugs, only two were submitted and four were approved first in Canada; moreover, the mean review time in Canada (423 days) was longer than that in the US (mean = 341 days), a statistically significant difference (t[39] = 2.04, p = 0.048). These results raise questions about what motivated Canada's apparent shift in orphan drug policy. Copyright © 2016 Longwoods Publishing.

A review of the literature (1998 to 2014) was performed to identify relevant, peer-reviewed articles. Using content analysis, we synthesised regulations and policies for access to orphan drugs by type and by country. Fifty seven articles and 35 countries were included in this review. Six broad categories of regulation and policy instruments were identified: national orphan drug policies, orphan drug designation, marketing authorization, incentives, marketing exclusivity, and pricing and reimbursement. The availability of orphan drugs depends on individual country's legislation and regulations including national orphan drug policies, orphan drug designation, marketing authorization, marketing exclusivity and incentives such as tax credits to ensure research, development and marketing. The majority of countries (27/35) had in place orphan drug legislation. Access to orphan drugs depends on individual country's pricing and reimbursement policies, which varied widely between countries. High prices and insufficient evidence often limit orphan drugs from meeting the traditional health technology assessment criteria, especially cost-effectiveness, which may influence access. Overall many countries have implemented a combination of legislations, regulations and policies for orphan drugs in the last two decades. While these may enable the availability and access to orphan drugs, there are critical differences between countries in terms of range and types of legislations, regulations and policies implemented. Importantly, China and India, two of the largest countries by population size, both lack national legislation for orphan medicines and rare diseases, which could have substantial negative impacts on their patient populations with rare diseases.

  19. Reference drug programs: Effectiveness and policy implications☆

    Science.gov (United States)

    Schneeweiss, Sebastian

    2010-01-01

    In the current economic environment, health care systems are constantly struggling to contain rapidly rising costs. Drug costs are targeted by a wide variety of measures. Many jurisdictions have implemented reference drug programs (RDPs) or similar therapeutic substitution programs. This paper summarizes the mechanism and rationale of RDPs and presents evidence of their economic effectiveness and clinical safety. RDPs for pharmaceutical reimbursement are based on the assumption that drugs within specified medication groups are therapeutically equivalent and clinically interchangeable and that a common reimbursement level can thus be established. If the evidence documents that a higher price for a given drug does not buy greater effectiveness or reduced toxicity, then under RDP such extra costs are not covered. RDPs or therapeutic substitutions based on therapeutic equivalence are seen as logical extensions of generic substitution that is based on bioequivalence of drugs. If the goal is to achieve full drug coverage for as many patients as possible in the most efficient manner, then RDPs in combination with prior authorization programs are safer and more effective than simplistic fiscal drug policies, including fixed co-payments, co-insurances, or deductibles. RDPs will reduce spending in the less innovative but largest market, while fully covering all patients. Prior authorization will ensure that patients with a specified indication will benefit from the most innovative therapies with full coverage. In practice, however, not all patients and drugs will fit exactly into one of the two categories. Therefore, a process of medically indicated exemptions that will consider full coverage should accompany an RDP. In the current economic environment, health care systems are constantly struggling to contain rapidly rising costs. Drug costs are targeted by a wide variety of measures. Many jurisdictions have implemented reference drug programs, and others are considering

    OBJECTIVE Analyze the implementation of drug price regulation policy by the Drug Market Regulation Chamber. METHODS This is an interview-based study, which was undertaken in 2012, using semi-structured questionnaires with social actors from the pharmaceutical market, the pharmaceuticals industry, consumers and the regulatory agency. In addition, drug prices were compiled based on surveys conducted in the state of Sao Paulo, at the point of sale, between February 2009 and May 2012. RESULTS The mean drug prices charged at the point of sale (pharmacies) were well below the maximum price to the consumer, compared with many drugs sold in Brazil. Between 2009 and 2012, 44 of the 129 prices, corresponding to 99 drugs listed in the database of compiled prices, showed a variation of more than 20.0% in the mean prices at the point of sale and the maximum price to the consumer. In addition, many laboratories have refused to apply the price adequacy coefficient in their sales to government agencies. CONCLUSIONS The regulation implemented by the pharmaceutical market regulator was unable to significantly control prices of marketed drugs, without succeeding to push them to levels lower than those determined by the pharmaceutical industry and failing, therefore, in its objective to promote pharmaceutical support for the public. It is necessary reconstruct the regulatory law to allow market prices to be reduced by the regulator as well as institutional strengthen this government body. PMID:26083945

    Objective To review existing regulations and policies utilised by countries to enable patient access to orphan drugs. Methods A review of the literature (1998 to 2014) was performed to identify relevant, peer-reviewed articles. Using content analysis, we synthesised regulations and policies for access to orphan drugs by type and by country. Results Fifty seven articles and 35 countries were included in this review. Six broad categories of regulation and policy instruments were identified: national orphan drug policies, orphan drug designation, marketing authorization, incentives, marketing exclusivity, and pricing and reimbursement. The availability of orphan drugs depends on individual country’s legislation and regulations including national orphan drug policies, orphan drug designation, marketing authorization, marketing exclusivity and incentives such as tax credits to ensure research, development and marketing. The majority of countries (27/35) had in place orphan drug legislation. Access to orphan drugs depends on individual country’s pricing and reimbursement policies, which varied widely between countries. High prices and insufficient evidence often limit orphan drugs from meeting the traditional health technology assessment criteria, especially cost-effectiveness, which may influence access. Conclusions Overall many countries have implemented a combination of legislations, regulations and policies for orphan drugs in the last two decades. While these may enable the availability and access to orphan drugs, there are critical differences between countries in terms of range and types of legislations, regulations and policies implemented. Importantly, China and India, two of the largest countries by population size, both lack national legislation for orphan medicines and rare diseases, which could have substantial negative impacts on their patient populations with rare diseases.

    This paper places America's "war on drugs" in perspective in order to develop a new metaphor for control of drug misuse. A brief and focused history of America's experience with substance use and substance use policy over the past several hundred years provides background and a framework to compare the current Pharmacological Revolution with America's Nineteenth Century Industrial Revolution. The paper concludes with cautions about growing challenges and provides suggestions for navigating this revolution and reducing its negative impact on individuals and society.

    Since economic liberalization in the late 1970s, China's health care providers have grown heavily reliant on revenue from drugs, which they both prescribe and sell. To curb abuse and to promote the availability, safety, and appropriate use of essential drugs, China introduced its national essential drug list in 2009 and implemented a zero markup policy designed to decouple provider compensation from drug prescription and sales. We collected and analyzed representative data from China's township health centers and their catchment-area populations both before and after the reform. We found large reductions in drug revenue, as intended by policy makers. However, we also found a doubling of inpatient care that appeared to be driven by supply, instead of demand. Thus, the reform had an important unintended consequence: China's health care providers have sought new, potentially inappropriate, forms of revenue.

    Clark, Claire D; Dufton, Emily

    2015-02-01

    As President Jimmy Carter's advisor for health issues, Peter Bourne promoted a rational and comprehensive drug strategy that combined new supply-side efforts to prevent drug use with previously established demand-side addiction treatment programs. Using a public health ethic that allowed the impact of substances on overall population health to guide drug control, Bourne advocated for marijuana decriminalization as well as increased regulations for barbiturates. A hostile political climate, a series of rumors, and pressure from both drug legalizers and prohibitionists caused Bourne to resign in disgrace in 1978. We argue that Bourne's critics used his own public health framework to challenge him, describe the health critiques that contributed to Bourne's resignation, and present the story of his departure as a cautionary tale for today's drug policy reformers.

    The mantra of evidence-based policy (EBP) suggests that endeavours to implement evidence-based policing will produce better outcomes. However there is dissonance between the rhetoric of EBP and the actuality of policing policy. This disjuncture is critically analysed using the case study of illicit drugs policing. The dissonance may be ameliorated…

  7. Risk control and rational recreation: A qualitative analysis of synthetic drug use among young urbanites in China.

    2014-07-01

    To fight against the rapid growth of synthetic drugs, the Chinese government has strengthened the controls and regulation, incorporated synthetic drugs into the new detoxification system, and changed the inconsistent governance of synthetic and traditional drugs. This, however, has not stopped the spread of synthetic drugs among young urbanites. While scholars have focused on the loopholes and defects of specific drug control regulations, ethnographic inquiries illustrate how and why control does not work, or is even resisted by young drug users. In-depth qualitative interviews were conducted with 28 individuals aged between 20 and 35, recruited from a cohort of synthetic drug users in a Shanghai drug rehabilitation centre. Audio-recorded interviews elicited accounts of their daily experiences of drug use as well as their perspectives on the impact of the government's new drug control policies. The main themes voiced by our respondents include: (1) synthetic drugs are not addictive, and are used to feel 'high'; (2) synthetic drugs are used to achieve their goals, which are otherwise impossible through mainstream means; (3) users are confident that they will be able to manage the use of synthetic drugs without harm to themselves; (4) their worries concern administrative punishment rather than consequences to health. The participants of this study did not support the government's attempts to control the use of synthetic drugs. They viewed their use as rational recreation under the perceived boundaries of 'acceptable risks'. Even in the context of severe control, synthetic drugs have strong appeal to youths. Drug policy should acknowledge the experiences of users and consider the socio-cultural contexts of youth drug-taking. The personal experience of participants could help improve the Chinese Drug Control Act and regulations. Copyright © 2014 Elsevier B.V. All rights reserved.

    The increase in the consumption of generic drugs to reduce pharmaceutical expenditure is a challenge for many countries, especially during the economic crisis. The purpose of the present study is to review the Greek market of generic drugs and the decisions that shape it, to determine the factors that affect Greek patients' and doctors' attitudes about generic substitution and present a set of measures for all stakeholders based on the findings of the secondary and primary analysis. The study includes (a) an analysis of international and national reports and legislation on drugs policies and (b) a questionnaire survey of 242 hospital patients and 85 doctors regarding their perceptions on generics. A small increase in the volume of generics is recorded, yet not followed by sales value, over the recent years that the measures for promoting generics prescription took effect. Distrust from both patients and doctors was observed toward generics' effectiveness and toward the appropriateness of the regulatory authorities' quality controls. The study presents a structured set of viable measures, applicable to many countries, for promoting generic drug consumption that can lead to economic efficiency without degrading the health care quality.

    The expense of acquiring antiretroviral drugs in Brazil has given rise to debate about the sustainability of the policy of universal access to AIDS medications, despite the evident benefits. The objective of this study was to analyze the evolution of the Ministry of Health's spending on acquiring antiretroviral drugs from 1998 to 2005, the determining factors and the medium-term sustainability of this policy (2006-2008). The study on the evolution of spending on antiretrovirals included analysis of their prices, the year-by-year expenditure, the number of patients utilizing the medication, the mean expenditure per patient and the strategies for reducing the prices maintained during this period. To analyze the sustainability of the policy for access to antiretrovirals, the cost of acquiring the drugs over the period from 2006 to 2008 was estimated, along with the proportion of gross domestic product and federal health expenditure represented by this spending. The data were collected from the Ministry of Health, the Brazilian Institute for Geography and Statistics (IBGE) and the Ministry of Planning. The expenditure on antiretrovirals increased by 66% in 2005, breaking the declining trend observed over the period from 2000 to 2004. The main factors associated with this increase were the weakening of the national generics industry and the unsatisfactory results from the process of negotiating with pharmaceutical companies. The Brazilian policy for universal access is unsustainable at the present growth rates of the gross domestic product, unless the country compromises its investments in other fields.

  11. Models of policy-making and their relevance for drug research.

    Ritter, Alison; Bammer, Gabriele

    2010-07-01

    Researchers are often frustrated by their inability to influence policy. We describe models of policy-making to provide new insights and a more realistic assessment of research impacts on policy. We describe five prominent models of policy-making and illustrate them with examples from the alcohol and drugs field, before drawing lessons for researchers. Policy-making is a complex and messy process, with different models describing different elements. We start with the incrementalist model, which highlights small amendments to policy, as occurs in school-based drug education. A technical/rational approach then outlines the key steps in a policy process from identification of problems and their causes, through to examination and choice of response options, and subsequent implementation and evaluation. There is a clear role for research, as we illustrate with the introduction of new medications, but this model largely ignores the dominant political aspects of policy-making. Such political aspects include the influence of interest groups, and we describe models about power and pressure groups, as well as advocacy coalitions, and the challenges they pose for researchers. These are illustrated with reference to the alcohol industry, and interest group conflicts in establishing a Medically Supervised Injecting Centre. Finally, we describe the multiple streams framework, which alerts researchers to 'windows of opportunity', and we show how these were effectively exploited in policy for cannabis law reform in Western Australia. Understanding models of policy-making can help researchers maximise the uptake of their work and advance evidence-informed policy.

    Full Text Available Abstract Background Following the recognition that morbidity and mortality due to malaria had dramatically increased in the last three decades, in 2002 the government of Zambia reviewed its efforts to prevent and treat malaria. Convincing evidence of the failing efficacy of chloroquine resulted in the initiation of a process that eventually led to the development and implementation of a new national drug policy based on artemisinin-based combination therapy (ACT. Methods All published and unpublished documented evidence dealing with the antimalarial drug policy change was reviewed. These data were supplemented by the authors' observations of the policy change process. The information has been structured to capture the timing of events, the challenges encountered, and the resolutions reached in order to achieve implementation of the new treatment policy. Results A decision was made to change national drug policy to artemether-lumefantrine (AL in the first quarter of 2002, with a formal announcement made in October 2002. During this period, efforts were undertaken to identify funding for the procurement of AL and to develop new malaria treatment guidelines, training materials, and plans for implementation of the policy. In order to avoid a delay in implementation, the policy change decision required a formal adoption within existing legislation. Starting with donated drug, a phased deployment of AL began in January 2003 with initial use in seven districts followed by scaling up to 28 districts in the second half of 2003 and then to all 72 districts countrywide in early 2004. Conclusion Drug policy changes are not without difficulties and demand a sustained international financing strategy for them to succeed. The Zambian experience demonstrates the need for a harmonized national consensus among many stakeholders and a political commitment to ensure that new policies are translated into practice quickly. To guarantee effective policies requires

    McCann, Eugene; Temenos, Cristina

    2015-01-01

    This article discusses the learning and politics involved in spreading Drug Consumption Rooms (DCRs) globally. DCRs are health facilities, operating under a harm reduction philosophy, where people consume illicit drugs in a supervised setting. Approximately 90 are located in almost 60 cities in 11 countries. They are intensely local attempts to improve the lives of specific populations and urban neighborhoods. DCRs are also global models that travel. This article examines the relationship between DCRs as facilities that are fixed in place and DCRs as globally-mobilized models of drug policy and public health practice. Drawing on research from seven countries, we apply concepts from the policy mobilities literature to analyze the travels of the DCR model and the political strategies involved in the siting of these public health service facilities. We detail the networked mobilization of the DCR model from Europe to Canada and Australia, the learning among facilities, the strategies used to mold the DCR model to local contexts, and the role of DCR staff in promoting continued proliferation of DCRs. We conclude by identifying some immobilities of DCRs to identify questions about practices, principles and future directions of harm reduction. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Public attitudes about drug addiction and mental illness were compared. A Web-based national survey (N=709) was conducted to compare attitudes about stigma, discrimination, treatment effectiveness, and policy support in regard to drug addiction and mental illness. Respondents held significantly more negative views toward persons with drug addiction. More respondents were unwilling to have a person with drug addiction marry into their family or work closely with them. Respondents were more willing to accept discriminatory practices against persons with drug addiction, more skeptical about the effectiveness of treatments, and more likely to oppose policies aimed at helping them. Drug addiction is often treated as a subcategory of mental illness, and insurance plans group them together under the rubric of "behavioral health." Given starkly different public views about drug addiction and mental illness, advocates may need to adopt differing approaches to reducing stigma and advancing public policy.

    Limited information is present in literature regarding detection of illicit drug users visiting physicians when planning elective surgery; also, there is no update manuscript that is illustrating the effects of illicit drugs use that require reconstructive surgery interventions. Aims of this manuscript are: 1) to summarize existing knowledge, and give surgeons information how to detect patients who might possible use illicit drugs; 2) to review the effects of illicit drug use that specifically require reconstructive surgery interventions; 3) to assess on existing policies on asymptomatic illicit drug users when planning elective surgery. Studies were identified by searching systematically in the electronic databases PubMed, Medline, The Cochrane Library and SveMed+. Because of the nature of research questions to be investigated (drug policy and surgery), a "systematic review" was not possible. In spite of some existing policies to detect illicit drug use in specific situations such as workplaces or acute trauma patients, there is a lack of data and lack of information, and subsequently no policy has ever been made, for detection and management of illicit drug use asymptomatic patients requesting or referred for plastic surgery interventions. This manuscript poses questions for further ethical evaluations and future policy. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd. All rights reserved.

  17. Problem Drug Use, Marijuana, and European Projects: How Epidemiology Helped Czech Policy Reformers

    2008-12-01

    Full Text Available I examine the transfer of the Problem Drug Use (PDU concept into Czech scientific discourse through European institutions’ projects, and view PDU’s utilization by Czech researchers in relation to marijuana decriminalization efforts.PDU is defined as intravenous and/or long-term and regular use of opiates, cocaine, or amphetamines. Out of a vast array of illicit drug use patterns, this concept isolates a relatively small population with the riskiest use patterns to become the focus of public policies. A series of European Union and Council of Europe projects in 1990’s helped bring PDU into European research mainstream. The new common standard, promoted by the European Monitoring Centre for Drugs and Drug Addiction, was utilized by Czech authors in a 2001 policy analysis entitled “Impact Analysis Project of the New Drug Legislation in the Czech Republic” (PAD. PDU played a crucial role in PAD’s drug problem modeling, focusing on a “hard core” of opiate and methamphetamine users, while diverting attention from a large group of cannabis users.By using the new European methodological standard, PAD’s authors constructed marijuana as a non-problem. This helped drug policy reformers in the Czech Government legitimize their focus on “harder” drugs, and subsequently propose more lenient sanctions for the possession and cultivation of marijuana. I argue that continued ignorance of marijuana problems might jeopardize the tolerant expert-driven drug policy in the Czech Republic. Measurement of problem cannabis use should be introduced.

    2013-06-01

    This contribution provides an overview of different approaches used to analyse drug policies within and across countries. Besides the great number of cost of illness studies which have contributed to the assessment of health harms and risks associated to the drug use, most of the recent efforts have focused on the creation of synthetic indices to classify countries around the world or to evaluate particular law enforcement policies in some countries. This is probably due to a general lack of comparable data across countries. The wide variety of budgetary practices in the drugs field in Europe contributes to the problems that exist in estimating drug-related public expenditure. These heterogeneous accounting practices, together with the complexity of the drug phenomenon and the multiplicity of perspectives on the issue, strongly constrains the possibility of economically evaluate and compare drug laws across countries.

    At present, China has achieved an initial establishment and gradual implementation of a framework for national essential drugs policy. With the further implementation of the national essential drugs policy, it is not clear how the policy works, whether it achieves the original intention of essential drugs policy, and what impact essential drugs policy exerts on the primary health care system. In view of it, we conducted a field research on sample areas of Shandong Province to understand the conditions of the implementation of the essential drugs policy in Shandong Province. From three perspectives of medical institutions, patients and medical staff, this thesis analyzes the impact of essential drugs policy on village-level and township-level health service system, summarizes the effectiveness of implementing essential drugs policy, discovers the problems of various aspects and conducts an in-depth analysis of the causes, and puts forward feasible suggestions to provide reference for improving the essential drugs policy. The assessment results show that the implementation of essential drugs policy in Shandong Province has played a positive role in promoting the sound development of the primary health care system, changed the situation of covering hospital expenses with medicine revenue in the past, contributed to the return of medical institutions to public welfare, and reduced the patient's economic burden of disease. But there emerge many problems as follows: impact on the doctor's diagnosis and treatment due to incompleteness of drug types, and distribution not in place, patient loss and operational difficulty of village clinic. Thus, this thesis makes recommendations of drugs catalog formulation, drug procurement, sales and use, and meanwhile points out that the supporting financial compensation policy and performance appraisal policy and other measures in place are a prerequisite for a positive role of essential drugs policy.

    2016-07-01

    One of the challenges with respect to public health and the abuse of alcohol and other drugs is to implement policies in support of greater co-ordination among various levels of government. In Brazil, policies are formulated by the Secretaria Nacional de Políticas sobre Drogas (SENAD - State Department for Policies on Drugs) and the Ministério da Saúde (MS - Ministry of Health). This study aims to compare implementation of policies adopted by SENAD and MS at the municipal level. Three municipalities were intentionally selected: Juiz de Fora having a larger network of treatment services for alcohol and drug users; Lima Duarte, a small municipality, which promotes the political participation of local actors (COMAD - Municipal Council on Alcohol and Drugs); and São João Nepomuceno, also a small municipality, chosen because it has neither public services specialised to assist alcohol and other drugs users, nor COMAD. Data collection was conducted through interviews with key informants (n = 19) and a review of key documents concerned with municipal policies. Data analysis was performed using content analysis. In Juiz de Fora, there are obstacles regarding the integration of the service network for alcohol and other drug users and also the articulation of local actors, who are predominant in the mental health sector. In Lima Duarte, while there is a link between local actors through COMAD, their actions within the local service network have not been effective. In São João Nepomuceno, there were no public actions in the area of alcohol and drugs, and consequently insufficient local debate. However, some voluntary, non-governmental work has been undertaken. There were weaknesses in the implementation of national-level policies by SENAD and the MS, due to the limited supply of available treatment, assistance and the lack of integration among local actors. © 2015 John Wiley & Sons Ltd.

    The aim of our study was to investigate the changes in drug usage and financial expenditure according to legal changes in Croatia during the period 2001 - 2008, especially considering pricing policy. The data on outpatient drug usage during the studied period was obtained from the Croatian National Health Insurance (CNHI). CNHI maintains a database on drugs prescribed by primary health care physicians and dispensed by pharmacies. The data was calculated and presented in defined daily doses (DDD) per inhabitant per year for antibiotics and in DDD/1,000 inhabitants/day for other drugs. The data is also presented in Euro/DDD and the financial expenditures are presented in Euros. During the investigated period drug usage increased 81.33%, while financial expenditure increased 77.23%. While total DDD/1,000 increased ~ 10% every year, financial expenditure increased 10 - 20% annually until 2006, but since then there have been no significant changes. Pricing policy changes could influence drug financial expenditure considerably in the short-term, but it is also important to apply a combination of measures for drug expenditure control. Numerous interventions from authorities from different countries all over the world, prove that there is still no so called "gold standard" which could restrain growing usage and expenditure of drugs. Clinical pharmacologists and clinical pharmacists should be included in these processes.

    To describe alternative policies aimed at encouraging price competition in generic drug markets in countries with strict price regulation, and to present some case studies drawn from the European experience. Systematic literature review of articles and technical reports published after 1999. The shortcomings in consumer price competition observed in some European generic markets, including Spain, may be reduced through three types of public reimbursement or financing reforms: policies aimed at improving the design of current maximum reimbursement level policies; policies aimed at monitoring competitive prices in order to reimburse real acquisition cost to pharmacies; and, more radical and market-oriented policies such as competitive tendering of public drug purchases. The experience of recent reforms adopted in Germany, Belgium, Holland, Norway, and Sweden offers a useful guide for highly price-regulated European countries, such as Spain, currently characterized by limited consumer price competition and the high discounts offered to pharmacy purchases. Direct price regulation and/or the generic reference pricing systems used to reduce generic drug prices in many European countries can be successfully reformed by adopting measures more closely aimed at encouraging consumer price competition in generic drug markets.

    The high frequency of criminal behaviour and related legal problems associated with substance addiction generates a field of interaction between legal and healthcare systems. This study was developed as a multicentre project to investigate the opinions of professionals from legal and healthcare systems about policies on illegal drugs and their implementation in practice. A multiple choice questionnaire designed ad hoc was administered to a sample of 230 professionals from legal and healthcare fields working in the cities of Barcelona, Granada and Bilbao. The questionnaire included sociodemographic and work-related data, and assessed interviewees' information about the response to drug-related crime and opinion on drug policy issues. This article presents the results from Spain. The main results showed that both groups of professionals value alternative measures to imprisonment (AMI) as useful tools to prevent offenses related to drug use and claim a broader application of AMI. They also evaluated positively the regulations on cannabis use in effect. Though the attitude of healthcare professionals towards the application of AMI is more permissive, both groups favour restricting these sanctions in cases of recidivism. Both groups show mild satisfaction with the current addiction healthcare system and express dissatisfaction with actual drug policies in Spain.

    Full Text Available Research & Development (R&D plays an increasingly important role in China’s pharmaceutical industry. To gain a competitive edge in the global pharmaceutical market, the current national strategy of China forcefully pushes for independent drug innovations. This article investigates the historical, legal, and institutional contexts in which China’s drug R&D has evolved. Based on an analysis of the drug R&D evolution and national policies in China, it predicts the future trend of China’s policies relevant to drug innovations. This paper helps to understand the impact of national policies on drug R&D in China, which can be used to inform decision-making on investments in China’s pharmaceutical market or conducting technology trade and international cooperation with Chinese partners.

  7. The cocaine and heroin markets in the era of globalisation and drug reduction policies.

    Despite the large volume of public effort devoted to restrain drug supply and the growing attention given to drug demand reduction policies, the use of cocaine and heroin remains steady. Furthermore, retail drug prices have fallen significantly in Europe and the US. This puzzling evidence leads us to develop a model aiming at systematically analysing illicit drug markets. We model the markets of cocaine and heroin from production to the final retail markets. One novelty of the analysis consists in characterising the retail market as a monopolistic competitive one. Then, upper level dealers have some market power in the retail market. This allows them to charge a markup and to earn extra profits. These extra profits attract newcomers so that profits tend to fall over time. Theoretical model was used to analyse the effect of supply containment policies on the retail market, the producer market and the export-import business. This introduces the discussion of the impact of demand reduction policies on the high level traffickers' profit. Finally, globalisation enters in the model. Law enforcement measures increase the risk premia received by the lower and higher level traffickers. Consequently, trafficking intermediation margins tend to increase. However, globalisation has the opposite effect. It lowers intermediation margins and, then, pushes retail prices down, thereby stimulating consumption. In doing so, globalisation offsets the effects of supply containment policies. Finally, we discuss how the effectiveness of supply containment policies can be enhanced by combining them with demand reduction policies.

    Since 2010, the memoranda of understanding were implemented in Greece as a measure of fiscal adjustment. Public pharmaceutical expenditure was one of the main focuses of this implementation. Numerous policies, targeted on pharma spending, reduced the pharmaceutical budget by 60.5%. Yet, generics' penetration in Greece remained among the lowest among OECD countries. This study aims to highlight the factors that affect the perceptions of the population on generic drugs and to suggest effective policy measures. The empirical analysis is based on a national cross-sectional survey that was conducted through a sample of 2003 individuals, representative of the general population. Two ordinal logistic regression models were constructed in order to identify the determinants that affect the respondents' beliefs on the safety and the effectiveness of generic drugs. The empirical findings presented a positive and statistically significant correlation with income, bill payment difficulties, safety and effectiveness of drugs, prescription and dispensing preferences and the views toward pharmaceutical companies. Also, age and trust toward medical community have a positive and statistically significant correlation with the perception on the safety of generic drugs. Policy interventions are suggested on the bases of the empirical results on 3 major categories; (a) information campaigns, (b) incentives to doctors and pharmacists and (c) to strengthen the bioequivalence control framework and the dissemination of results.

  9. "Coca got us here and now it's our weakness:" Fusarium oxysporum and the political ecology of a drug war policy alternative in Bolivia.

    2016-07-01

    A strain of Fusarium oxysporum fungus is killing coca plants in the Chapare coca growing region of Bolivia. Coca farmers are already constrained in the amount of coca they can grow under the government's community-based coca control approach, "social control." Coca leaf is the main ingredient in cocaine, but it is also a traditional medicine and food, is economically vital to household incomes, and is a political symbol of the current government administration. Bolivia's approach to coca control, now administered without any United States military intervention, is an innovative example of experimentation with drug policy reform. This paper is based on ethnographic research including semi-structured interviews and observation. Coca growers are worried about the dire economic, social, and political consequences of the fungus' appearance and spread since summer 2013. They have two explanations for its origins: First, that it was sent by the United States government, which in the past was developing a strain of F. oxysporum for use in the drug war; Second, and the explanation of scientists, is that the outbreak is caused by the overuse of agrochemicals and other intensive agricultural practices. More than a matter of agroecology, the practices identified in the second explanation must be understood in terms of the persistence of the international drug prohibition regime. Bolivia's social control approach is a successful alternative to violent eradication measures, however the country is constrained to uphold the fundamental principles of supply-side control in order to be a respected partner in global drug control. The supply-side logics restricting social control make intensive agriculture practices attractive, but may have contributed to the fungus' proliferation and its continued spread. The fungus draws attention to the challenges of policy reform, new collateral damages of drug control, and role environmental factors can play in drug control politics. Copyright

  11. 'Social evils' and harm reduction: the evolving policy environment for human immunodeficiency virus prevention among injection drug users in China and Vietnam.

    This paper reviews the evolution of government policies in China and Vietnam regarding harm reduction interventions for human immunodeficiency virus (HIV) prevention, such as needle/syringe provision and opioid substitution treatment. The work is based upon the authors' experiences in and observations of these policy developments, as well as relevant government policy documents and legislation. Both countries are experiencing HIV epidemics driven by injection drug use and have maintained generally severe policies towards injection drug users (IDUs). In recent years, however, they have also officially endorsed harm reduction. We sought to understand how and why this apparently surprising policy evolution took place. Factors associated with growing support for harm reduction were similar but not identical in China and Vietnam. These included the emergence of effective 'champions' for such policies, an ethos of pragmatism and receptivity to evidence, growing collaboration across public health, police and other sectors, the influence of contingent events such as the severe acute respiratory syndrome (SARS) epidemic and pressure from donors and international organizations to adopt best practice in HIV prevention. Ongoing challenges and lessons learned include the persistence of tensions between drug control and harm reduction that may have negative effects on programs until a fully harmonized policy environment is established. Excessive reliance on law enforcement and forced detoxification will not solve the problems of substance abuse or of HIV among drug users. Ongoing evaluation of harm reduction programs, as well as increased levels of multi-sectoral training, collaboration and support are also needed.

    We assessed the prevalence and characteristics of prescription drug misuse among youth ages 15-25 to examine differences by student and employment status, and associations with workplace antidrug policies and programs. Multivariate logistic regressions analyzed associations in weighted data on the 20,457 young adults in the combined 2004-2008 National Surveys on Drug Use and Health. Demographic controls included sex, race, community size, and age group. After we accounted for demographic controls, at ages 15-25, students were less likely than nonstudents to misuse prescription drugs. Segmenting student from nonstudent groups, working consistently was associated with a further reduction in misuse for those ages 18-25. When we controlled for demographics and substance use history, both Employee Assistance Program (EAP) services and awareness that one's employer had a drug-free workplace policy were associated with significantly lower misuse of prescription drugs (OR = 0.85 for each program, 95% CI [0.73, 1.00] and [0.72, 1.00]). Associations of workplace antidrug policies and programs with marijuana use and with Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition, criteria for alcohol abuse and dependence contrasted sharply with these patterns. All four aspects were significantly associated with lower marijuana use. None was associated with problem drinking. Protective effects of drug-free workplace policy and EAPs persist after other substance use was controlled for. Comparing the effects of workplace programs on illicit drug use and problem drinking versus prescription misuse suggests that those protective associations do not result from selection bias. Thus, drug-free workplace policies and EAPs appear to help protect younger workers against prescription misuse. If workplace substance use disorder programs focused prevention messages and interventions on prescription drug misuse, their impact on misuse might increase.

    2007-05-01

    Full Text Available Abstract Backgound Sulphadoxine/sulphalene-pyrimethamine (SP was adopted in Kenya as first line therapeutic for uncomplicated malaria in 1998. By the second half of 2003, there was convincing evidence that SP was failing and had to be replaced. Despite several descriptive investigations of policy change and implementation when countries moved from chloroquine to SP, the different constraints of moving to artemisinin-based combination therapy (ACT in Africa are less well documented. Methods A narrative description of the process of anti-malarial drug policy change, financing and implementation in Kenya is assembled from discussions with stakeholders, reports, newspaper articles, minutes of meetings and email correspondence between actors in the policy change process. The narrative has been structured to capture the timing of events, the difficulties and hurdles faced and the resolutions reached to the final implementation of a new treatment policy. Results Following a recognition that SP was failing there was a rapid technical appraisal of available data and replacement options resulting in a decision to adopt artemether-lumefantrine (AL as the recommended first-line therapy in Kenya, announced in April 2004. Funding requirements were approved by the Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM and over 60 million US$ were agreed in principle in July 2004 to procure AL and implement the policy change. AL arrived in Kenya in May 2006, distribution to health facilities began in July 2006 coincidental with cascade in-service training in the revised national guidelines. Both training and drug distribution were almost complete by the end of 2006. The article examines why it took over 32 months from announcing a drug policy change to completing early implementation. Reasons included: lack of clarity on sustainable financing of an expensive therapeutic for a common disease, a delay in release of funding, a lack of comparative efficacy data

    Barry, Colleen L; McGinty, Emma Elizabeth; Pescosolido, Bernice; Goldman, Howard H.

    2014-01-01

    Objective This study compares current public attitudes about drug addiction with attitudes about mental illness. Methods A web-based national public opinion survey (N=709) was conducted to compare attitudes about stigma, discrimination, treatment effectiveness, and policy support. Results Respondents hold significantly more negative views toward persons with drug addiction compared to those with mental illness. More respondents were unwilling to have a person with drug addiction marry into their family or work closely with them on a job. Respondents were more willing to accept discriminatory practices, more skeptical about the effectiveness of available treatments, and more likely to oppose public policies aimed at helping persons with drug addiction. Conclusions Drug addiction is often treated as a sub-category of mental illness, and health insurance benefits group these conditions together under the rubric of behavioral health. Given starkly different public views about drug addiction and mental illness, advocates may need to adopt differing approaches for advancing stigma reduction and public policy. PMID:25270497

  16. Understanding tobacco control policy at the national level: bridging the gap between public policy and tobacco control advocacy

    2018-03-01

    Full Text Available Background While some countries have advanced tobacco control policies, other countries struggle to adopt and implement FCTC's measures. This presentation uncovers the main factors that explain such variations, taking insights from public policy and political science as a starting point for a case study. Methods A case study of tobacco control policy making in the Netherlands, covering the period from the 1960s until the present. The study consisted of a systematic search and analysis of documents and proceedings of parliamentary debates on tobacco policy, supplemented with 22 interviews with key informants from the government, health organisations, politicians, and the tobacco industry. In addition, documents from the Truth Tobacco Industry Documents database, pertaining to the influence of the tobacco industry on Dutch policy making, were analysed. Results The Dutch government started relatively late to regulate tobacco. The choices in tobacco control policy making at the national level and the tempo in which they are made are explained by the interaction of the five main elements of the tobacco control policy making process: Relatively stable context factors (constitutional structures, 'rules of the policy making game', national cultural values Relatively dynamic context factors (regime changes, EU regulation and FCTC guidelines, changing social norms, public support Transfer of ideas (availability and interpretation of scientific evidence Pro and anti-tobacco control networks and coalitions (their organisational and lobby strength Agenda-setting (changes in problem definition, issue framing, media advocacy Conclusions Despite worldwide convergence of tobacco control policies, accelerated by the ratification of the FCTC treaty by most nations, governments develop approaches to tobacco control in line with cultural values, ideological preferences and specific national institutional arrangements. There is no one-size-fits-all approach. The

    Al-Obaidi, Tamara A; Fletcher, Stephanie M

    2014-01-01

    Clandestine drug laboratories (CDLs) have been emerging and increasing as a public health problem in Australia, with methamphetamine being the dominant illegally manufactured drug. However, management and remediation of contaminated properties are still limited in terms of regulation and direction, especially in relation to public and environmental health practice. Therefore, this review provides an update on the hazards and health effects associated with CDLs, with a specific look at the management of these labs from an Australian perspective. Particularly, the paper attempts to describe the policy landscape for management of CDLs, and identifies current gaps and how further research may be utilised to advance understanding and management of CDLs and inform public health policies. The paper highlights a significant lack of evidence-based policies and guidelines to guide regulatory authority including environmental health officers in Australia. Only recently, the national Clandestine Drug Laboratory Guidelines were developed to assist relevant authority and specialists manage and carry out investigations and remediation of contaminated sites. However, only three states have developed state-based guidelines, some of which are inadequate to meet environmental health requirements. The review recommends well-needed inter-sectoral collaborations and further research to provide an evidence base for the development of robust policies and standard operating procedures for safe and effective environmental health management and remediation of CDLs.

    Mexico has experienced disproportionate drug-related harms given its role as a production and transit zone for illegal drugs destined primarily for the USA. In response, in 2009, the Mexican federal government passed legislation mandating pre-arrest diversion of drug-dependent individuals towards addiction treatment. However, this federal law was not specific about how the scale-up of the addiction treatment sector was to be operationalised. We therefore conducted in-depth qualitative interviews with key 'interactors' in fields affected by the federal legislation, including participants from the law enforcement, public health, addiction treatment, and governmental administration sectors. Among 19 participants from the municipal, state and federal levels were interviewed and multiple barriers to policy reform were identified. First, there is a lack of institutional expertise to implement the reform. Second, the operationalisation of the reform was not accompanied by a coordinated action plan. Third, the law is an unfunded mandate. Institutional barriers are likely hampering the implementation of Mexico's policy reform. Addressing the concerns expressed by interactors through the scale-up of services, the provision of increased training and education programmes for stakeholders and a coordinated action plan to operationalise the policy reform are likely needed to improve the policy reform process.

    Taiwan has implemented a national health insurance system for more than 20 years now. The benefits of pharmaceutical products and new drug reimbursement scheme are determined by the Expert Advisory Meeting and the Pharmaceutical Benefit and Reimbursement Scheme (PBRS) Joint Committee in Taiwan. To depict the pharmaceutical benefits and reimbursement scheme for new drugs and the role of health technology assessment (HTA) in drug policy in Taiwan. All data were collected from the Expert Advisory Meeting and the PBRS meeting minutes; new drug applications with HTA reports were derived from the National Health Insurance Administration Web site. Descriptive statistics were used to analyze the timeline of a new drug from application submission to reimbursement effective, the distribution of approved price, and the approval rate for a new drug with/without local pharmacoeconomic study. After the second-generation national health insurance system, the timeline for a new drug from submission to reimbursement effective averages at 436 days, and that for an oncology drug reaches an average of 742 days. New drug approval rate is 67% and the effective rate (through the approval of the PBRS Joint Committee and the acceptance of the manufacturer) is 53%. The final approved price is 53.6% of the international median price and 70% of the proposed price by the manufacturer. Out of 95 HTA reports released during the period January 2011 to February 2017, 28 applications (30%) conducted an HTA with a local pharmacoeconomic study, and all (100%) received reimbursement approval. For the remaining 67 applications (70%) for which HTA was conducted without a local pharmacoeconomic analysis, 54 cases (81%) were reimbursed. New drug applications with local pharmacoeconomic studies are more likely to get reimbursement. Copyright © 2018. Published by Elsevier Inc.

    The Internet is not only a vital medium for communication, entertainment, and commerce, but it is also an outlet for illicit drug sales. Although the U.S. Controlled Substances Act regulates access to certain drugs by requiring prescriptions, unique characteristics of the Internet create significant challenges for the enforcement of U.S. drug policies. In the late 1990s "no prescription Web sites" (NPWs) began to emerge, which allow persons to purchase drugs, such as opiates, without a prescription. Given the likely role of NPWs in increasing prescription drug abuse, health care professionals must develop and disseminate strategies for helping patients who are affected by these Web sites.

    A detailed examination is presented of the background to the reports and policy developments concerning drug dependence which emerged in Britain during the 1960s. Analysis of documents and interviews with policy makers, officials and doctors involved in the events of the period, reveal that explanatory models in terms of 'moral panic' or 'power struggle' tend to oversimplify the complex processes involved. The role in policy formation of the media, government departments and groups within the medical profession is considered. The patterns of conflict and convergence are seen to overlap simple lines of 'interest'--we find conflict within the medical profession, convergence between the Home Office (legal) and elements of the medical professions (medical). The resulting legal and institutional framework involved only loose guidelines from the centre about treatment, and the shape of policy was determined by individual doctors in the new hospital treatment centres. The apparent re-run of the 1960s being staged in the 1980s will require detailed research in the future in order to avoid superficial comparisons.

    In Ontario, approximately $3.8 billion is spent annually on publicly funded drug programs. The annual growth in Ontario Public Drug Program (OPDP) expenditure has been limited to 1.2% over the course of 3 years. Concurrently, the Ontario Drug Policy Research Network (ODPRN) was appointed to conduct drug class review research relating to formulary modernization within the OPDP. Drug class reviews by ODPRN incorporate a novel methodological technique called reimbursement-based economics, which focuses on reimbursement strategies and may be particularly relevant for policy-makers. To describe the reimbursement-based economics approach. Reimbursement-based economics aims to identify the optimal reimbursement strategy for drug classes by incorporating a review of economic literature, comprehensive budget impact analyses, and consideration of cost-effectiveness. This 3-step approach is novel in its focus on the economic impact of alternate reimbursement strategies rather than individual therapies. The methods involved within the reimbursement-based approach are detailed. To facilitate the description, summary methods and findings from a recent application to formulary modernization with respect to the drug class tryptamine-based selective serotonin receptor agonists (triptans) used to treat migraine headaches are presented. The application of reimbursement-based economics in drug policy reforms allows policy-makers to consider the cost-effectiveness and budget impact of different reimbursement strategies allowing consideration of the trade-off between potential cost savings vs increased access to cost-effective treatments. © 2015 American Headache Society.

    In 2009, Mexico decriminalized the possession of small amounts of illicit drugs for personal use in order to refocus law enforcement resources on drug dealers and traffickers. This study examines the spatial distribution of law enforcement encounters reported by people who inject drugs (PWID) in Tijuana, Mexico to identify concentrated areas of policing activity after implementation of the new drug policy. Mapping the physical location of law enforcement encounters provided by PWID (n = 461) recruited through targeted sampling, we identified hotspots of extra-judicial encounters (e.g., physical/sexual abuse, syringe confiscation, and money extortion by law enforcement) and routine authorized encounters (e.g., being arrested or stopped but not arrested) using point density maps and the Getis-Ord Gi* statistic calculated at the neighborhood-level. Approximately half of the participants encountered law enforcement more than once in a calendar year and nearly one third of these encounters did not result in arrest but involved harassment or abuse by law enforcement. Statistically significant hotspots of law enforcement encounters were identified in a limited number of neighborhoods located in areas with known drug markets. At the local-level, law enforcement activities continue to target drug users despite a national drug policy that emphasizes drug treatment diversion rather than punitive enforcement. There is a need for law enforcement training and improved monitoring of policing tactics to better align policing with public health goals.

    2007-03-01

    Full Text Available Abstract Background Much research has shown that the homeless have higher rates of substance abuse problems than housed populations and that substance abuse increases individuals' vulnerability to homelessness. However, the effects of housing policies on drug users' access to housing have been understudied to date. This paper will look at the "unofficial" housing policies that affect drug users' access to housing. Methods Qualitative interviews were conducted with 65 active users of heroin and cocaine at baseline, 3 and 6 months. Participants were purposively sampled to reflect a variety of housing statuses including homeless on the streets, in shelters, "doubled-up" with family or friends, or permanently housed in subsidized, unsubsidized or supportive housing. Key informant interviews and two focus group interviews were conducted with 15 housing caseworkers. Data were analyzed to explore the processes by which drug users receive information about different housing subsidies and welfare benefits, and their experiences in applying for these. Results A number of unofficial policy mechanisms limit drug users' access to housing, information and services, including limited outreach to non-shelter using homeless regarding housing programs, service provider priorities, and service provider discretion in processing applications and providing services. Conclusion Unofficial policy, i.e. the mechanisms used by caseworkers to ration scarce housing resources, is as important as official housing policies in limiting drug users' access to housing. Drug users' descriptions of their experiences working with caseworkers to obtain permanent, affordable housing, provide insights as to how access to supportive and subsidized housing can be improved for this population.

    By the year 2000, Canada faced high levels of illicit drug use and related harms. Simultaneously, a fundamental tension had raisen between continuing a mainly repression-based versus shifting to a more health-oriented drug policy approach. Despite a wealth of new data and numerous individual studies that have emerged since then, no comprehensive review of key indicators and developments of illicit drug use/harm epidemiology, interventions and law/policy exist; this paper seeks to fill this gap. We searched and reviewed journal publications, as well as key reports, government publications, surveys, etc. reporting on data and information since 2000. Relevant data were selected and extracted for review inclusion, and subsequently grouped and narratively summarized in major topical sub-theme categories. Cannabis use has remained the principal form of illicit drug use; prescription opioid misuse has arisen as a new and extensive phenomenon. While new drug-related blood-borne-virus transmissions declined, overdose deaths increased in recent years. Acceptance and proliferation of - mainly local/community-based - health measures (e.g., needle exchange, crack paraphernalia or naloxone distribution) aiming at high-risk drug users has evolved, though reach and access limitations have persisted; Vancouver's 'supervised injection site' has attracted continued attention yet remains un-replicated elsewhere in Canada. While opioid maintenance treatment utilization increased, access to treatment for key (e.g., infectious disease, psychiatric) co-morbidities among drug users remained limited. Law enforcement continued to principally focus on cannabis and specifically cannabis users. 'Drug treatment courts' were introduced but have shown limited effectiveness; several attempts cannabis control law reform have failed, except for the recent establishment of 'medical cannabis' access provisions. While recent federal governments introduced several law and policy measures reinforcing a

    Objectives. We examined the influence of tobacco control policies (tobacco control program expenditures, smoke-free air laws, youth access law compliance, and cigarette prices) on youth smoking outcomes (smoking susceptibility, past-year initiation, current smoking, and established smoking). Methods. We combined data from the 2002 to 2008 National Surveys on Drug Use and Health with state and municipality population data from the US Census Bureau to assess the associations between state tobacco control policy variables and youth smoking outcomes, focusing on youths aged 12 to 17 years. We also examined the influence of policy variables on youth access when these variables were held at 2002 levels. Results. Per capita funding for state tobacco control programs was negatively associated with all 4 smoking outcomes. Smoke-free air laws were negatively associated with all outcomes except past-year initiation, and cigarette prices were associated only with current smoking. We found no association between these outcomes and retailer compliance with youth access laws. Conclusions. Smoke-free air laws and state tobacco control programs are effective strategies for curbing youth smoking. PMID:23327252

    To assess the long-term effects of the introduction of China's zero-markup drug policy on hospitalisation expenditure and hospitalisation expenditures after reimbursement. An interrupted time series was used to evaluate the impact of the zero-markup drug policy on hospitalisation expenditure and hospitalisation expenditure after reimbursement at primary health institutions in Fufeng County of Shaanxi Province, western China. Two regression models were developed. Monthly average hospitalisation expenditure and monthly average hospitalisation expenditure after reimbursement in primary health institutions were analysed covering the period 2009 through to 2013. For the monthly average hospitalisation expenditure, the increasing trend was slowed down after the introduction of the zero-markup drug policy (coefficient = -16.49, P = 0.009). For the monthly average hospitalisation expenditure after reimbursement, the increasing trend was slowed down after the introduction of the zero-markup drug policy (coefficient = -10.84, P = 0.064), and a significant decrease in the intercept was noted after the second intervention of changes in reimbursement schemes of the new rural cooperative medical insurance (coefficient = -220.64, P markup drug policy in western China. However, hospitalisation expenditure and hospitalisation expenditure after reimbursement were still increasing. More effective policies are needed to prevent these costs from continuing to rise. © 2016 John Wiley & Sons Ltd.

  20. Controlling prescription drug costs: regulation and the role of interest groups in Medicare and the Veterans Health Administration.

    Science.gov (United States)

    2008-12-01

    Medicare and the Veterans Health Administration (VA) both finance large outpatient prescription drug programs, though in very different ways. In the ongoing debate on how to control Medicare spending, some suggest that Medicare should negotiate directly with drug manufacturers, as the VA does. In this article we relate the role of interest groups to policy differences between Medicare and the VA and, in doing so, explain why such a large change to the Medicare drug program is unlikely. We argue that key policy differences are attributable to stable differences in interest group involvement. While this stability makes major changes in Medicare unlikely, it suggests the possibility of leveraging VA drug purchasing to achieve savings in Medicare. This could be done through a VA-administered drug-only benefit for Medicare-enrolled veterans. Such a partnership could incorporate key elements of both programs: capacity to accept large numbers of enrollees (like Medicare) and leverage to negotiate prescription drug prices (like the VA). Moreover, it could be implemented at no cost to the VA while achieving savings for Medicare and beneficiaries.

In a context of scarce resources, doctors are required to take opportunity cost into account when prescribing treatments, while cost containment policies cannot overlook their active role in determining health care resource allocation. This paper addresses this issue, investigating the effects of cost containment measures in the market of biosimilar drugs that represent a viable and cost-saving strategy for the reduction of health care expenditure. The analysis focuses on a particular region in Italy, where several timely policies to incentivize biosimilar prescribing were launched. Methods: Drugs were identified by the anatomical therapeutic chemical classification system. Information about biosimilar drugs and their originator biological products was extracted from the IMS Health regional database. Drug consumption was expressed in terms of counting units, while expenditure was evaluated in Euro (€.The market penetration of biosimilars was analyzed by year and quarterly. Results: In the Campania region of Italy, the effects of cost containment policies, launched between 2009 and 2013, showed the prescription of biosimilars strongly increasing in 2010 until prescribing levels reached and exceeded the market share of the reference biological products in 2012. After a slight reduction, a plateau was observed at the beginning of 2013. At the same time, the use of the originator products had been decreasing until the first quarter of 2011. However, after a 1-year plateau, this trend

A simple account is given of the technical nature of nuclear hazards and of the legal and administrative framework that has been constructed to control them. The subsequent analysis concentrates primarily on the influence exerted by social and political factors. Particular attention is directed to those political groups which have developed a special interest in the problems of nuclear power, and to the interplay between organised groupings and public opinion generally. The metamorphosis of these groupings is traced from the origins of the nuclear industry in the Second World War to their prominent role during the Windscale Inquiry. Attention is given to the policy constraint imposed by increased expectations in the form of demands for higher standards of living, and improvements in the quality of the environment. The study is concerned with both policy-making and with policy implementation; with interest articulation as well as with the functioning of formal institutions. The evolution of policy takes place in an atmosphere of keen economic debate and conflicting moral perceptions. A model of the policy-making system is postulated.

    There are few studies exploring the social context of controlled drug use amongst young people in Indonesia. This qualitative study examines the experience of young people in a slum area (lorong) in Makassar, eastern Indonesia, who use drugs but are not drug dependent and who employ various forms of self regulation to control their use. Semi-structured interviews were conducted with eight controlled drug users. The study found that whilst controlled drug users lived in a drug risk environment, they were not deeply embedded in the street culture, risk-taking practises and drug scene within their locality. Their employment, albeit in the informal economy and in low-paid jobs, facilitated their perspective that the status of rewa (a local construct of masculinity) and gaul (being sociable and up-to-date) could and should be accomplished through conventional means such as jobs and halal (legitimate) income. Their employment generated both direct benefit (legitimate income) and indirect benefit, including meaningful activities, structured time, positive identity and wider social networks (bridging social capital). This enabled them to have a stake in mainstream society and provided an incentive to control drug use. All factors which are protective against escalation into problematic drug use. The study showed the importance of sociological concepts of direct and indirect benefits of employment and of social capital in understanding the social context of controlled drug use amongst young people in the lorong. Additionally, drug policy should be more cognizant of the social vulnerability in the lorong and of the need to increase access to employment amongst young people in order to potentially decrease the likelihood of problematic drug use.

  6. Tobacco control, global health policy and development: towards policy coherence in global governance

    Science.gov (United States)

    Collin, Jeff

    2015-01-01

    The WHO Framework Convention on Tobacco Control (FCTC) demonstrates the international political will invested in combating the tobacco pandemic and a newfound prominence for tobacco control within the global health agenda. However, major difficulties exist in managing conflicts with foreign and trade policy priorities, and significant obstacles confront efforts to create synergies with development policy and avoid tensions with other health priorities. This paper uses the concept of policy coherence to explore congruence and inconsistencies in objectives, policy, and practice between tobacco control and trade, development and global health priorities. Following the inability of the FCTC negotiations to satisfactorily address the relationship between trade and health, several disputes highlight the challenges posed to tobacco control policies by multilateral and bilateral agreements. While the work of the World Bank has demonstrated the potential contribution of tobacco control to development, the absence of non-communicable diseases from the Millennium Development Goals has limited scope to offer developing countries support for FCTC implementation. Even within international health, tobacco control priorities may be hard to reconcile with other agendas. The paper concludes by discussing the extent to which tobacco control has been pursued via a model of governance very deliberately different from those used in other health issues, in what can be termed ‘tobacco exceptionalism’. The analysis developed here suggests that non-communicable disease (NCD) policies, global health, development and tobacco control would have much to gain from re-examining this presumption of difference.

  7. Legislating thresholds for drug trafficking: a policy development case study from New South Wales, Australia.

    Legal thresholds are used in many parts of the world to define the quantity of illicit drugs over which possession is deemed "trafficking" as opposed to "possession for personal use". There is limited knowledge about why or how such laws were developed. In this study we analyse the policy processes underpinning the introduction and expansion of the drug trafficking legal threshold system in New South Wales (NSW), Australia. A critical legal and historical analysis was undertaken sourcing data from legislation, Parliamentary Hansard debates, government inquiries, police reports and research. A timeline of policy developments was constructed from 1970 until 2013 outlining key steps including threshold introduction (1970), expansion (1985), and wholesale revision (1988). We then critically analysed the drivers of each step and the roles played by formal policy actors, public opinion, research/data and the drug trafficking problem. We find evidence that while justified as a necessary tool for effective law enforcement of drug trafficking, their introduction largely preceded overt police calls for reform or actual increases in drug trafficking. Moreover, while the expansion from one to four thresholds had the intent of differentiating small from large scale traffickers, the quantities employed were based on government assumptions which led to "manifest problems" and the revision in 1988 of over 100 different quantities. Despite the revisions, there has remained no further formal review and new quantities for "legal highs" continue to be added based on assumption and an uncertain evidence-base. The development of legal thresholds for drug trafficking in NSW has been arbitrary and messy. That the arbitrariness persists from 1970 until the present day makes it hard to conclude the thresholds have been well designed. Our narrative provides a platform for future policy reform.

    Pharmaceuticals are important interventions that could improve people's health. Pharmaceutical pricing and purchasing policies are used as cost-containment measures to determine or affect the prices that are paid for drugs. Internal reference pricing establishes a benchmark or reference price within a country which is the maximum level of reimbursement for a group of drugs. Other policies include price controls, maximum prices, index pricing, price negotiations and volume-based pricing. To determine the effects of pharmaceutical pricing and purchasing policies on health outcomes, healthcare utilisation, drug expenditures and drug use.

Thus, it seems that social self-control is an alterable cognitive-behavioral attribute which can be improved through skill-based interventions in order to prevent drug use among adolescents. Policies aimed at preventing drug abuse among adolescents may benefit from institutionalizing social self-control skills training.

    Over the past few decades, numerous polymer drug carrier systems are designed and synthesized, and their properties are evaluated. Many of these systems are based on water-soluble polymer carriers of low-molecular-weight drugs and compounds, e.g., cytostatic agents, anti-inflammatory drugs, or multidrug resistance inhibitors, all covalently bound to a carrier by a biodegradable spacer that enables controlled release of the active molecule to achieve the desired pharmacological effect. Among others, the synthetic polymer carriers based on N-(2-hydroxypropyl) methacrylamide (HPMA) copolymers are some of the most promising carriers for this purpose. This review focuses on advances in the development of HPMA copolymer carriers and their conjugates with anticancer drugs, with triggered drug activation in tumor tissue and especially in tumor cells. Specifically, this review highlights the improvements in polymer drug carrier design with respect to the structure of a spacer to influence controlled drug release and activation, and its impact on the drug pharmacokinetics, enhanced tumor uptake, cellular trafficking, and in vivo antitumor activity. © 2017 WILEY-VCH Verlag GmbH & Co.

  11. Sameness and difference: metaphor and politics in the constitution of addiction, social exclusion and gender in Australian and Swedish drug policy.

    Like any other discourse, drug policy is imagined and articulated through metaphors. In this article, we explore the metaphors and meanings at work in the current national drug policies of Australia and Sweden. Australia's approach to welfare is usually characterised as liberal-welfarist, emphasising individual difference and 'freedom'. Sweden's approach is usually characterised as social-democratic, universalistic and paternalistic, with an emphasis on social rights, equity and sameness. How do these models of citizenship--difference versus sameness--play out in national drug policies? What are the risks and benefits of these models and the claims they allow? In the textual analysis presented here, we focus on metaphors and meanings relating to the themes of addiction, social exclusion and gender. We choose metaphor as our major analytical tool because we think that the risks and benefits of adopting different models of citizenship in drug policy need to be understood to operate at many levels and with a high degree of subtlety and abstraction. In the cases of addiction and social exclusion, a complicated picture emerges. In Australia, drug users are offered two options: sameness (and reintegration into society) or difference (and re-connection). In Sweden, drug users are excluded from society but not because they are fundamentally different from non-users. Because drug users are understood to be suffering from a temporary and curable personal affliction, the goal is to return them to sameness through care and treatment. With respect to gender, although differently expressed in the two national contexts and differently shaped by national imaginaries, both national policies adopt similar approaches: the unequal treatment of women transcends differences in national setting. Accounts of drug policy usually focus on the degree to which drug policy is, or should be, 'evidence-based', or on the complex political negotiations involving diverse stakeholders and interests

  12. Drug policy and global regulatory capitalism: the case of new psychoactive substances (NPS).

    Seddon, Toby

    2014-09-01

    The recent emergence of vibrant markets in 'new psychoactive substances' or 'legal highs' has posed significant new challenges for drug policy. These partly concern what to do about them but the speed and complexity of change has also raised difficulties for how policy responses should be developed. Existing drug policy systems appear too slow and cumbersome to keep up with the pace of change, remaining locked in large part within 'old' ways of thinking that centre almost exclusively around the deployment (or not) of the criminal law and its related enforcement apparatus. In this paper, it is argued that we need to rethink the problem through the lens of regulation, in order to learn lessons from other sectors where more agile responses to changing markets and business innovation have often proved possible. By examining examples drawn from these other areas, an alternative policy-making framework can be developed, involving a more flexible mix of state regulation, civil society action and private law mechanisms. This new approach is founded on a recognition of the networked and polycentric character of effective market governance in an era of global regulatory capitalism. Copyright © 2014 Elsevier B.V.

    2011-07-01

    Illicit drugs are never far from the media gaze and although identified almost a decade ago as 'a new battleground' for the alcohol and other drug (AOD) field there has been limited research examining the role of the news media and its effects on audiences and policy. This paper draws together media theories from communication literature to examine media functions. We illustrate how each function is relevant for media and drugs research by drawing upon the existing literature examining Australian media coverage during the late 1990s of escalating heroin-related problems and proposed solutions. Media can influence audiences in four key ways: by setting the agenda and defining public interest; framing issues through selection and salience; indirectly shaping individual and community attitudes towards risk; and feeding into political debate and decision making. Each has relevance for the AOD field. For example, media coverage of the escalating heroin-related problems in Australia played a strong role in generating interest in heroin overdoses, framing public discourse in terms of a health and/or criminal issue and affecting political decisions. Implications AND CONCLUSION: Media coverage in relation to illicit drugs can have multifarious effects. Incorporating media communication theories into future research and actions is critical to facilitate understanding of the short- and long-term impacts of media coverage on illicit drugs and the avenues by which the AOD field can mitigate or inform future media debates on illicit drugs. © 2010 Australasian Professional Society on Alcohol and other Drugs.

  14. Oral Drug Delivery Systems Comprising Altered Geometric Configurations for Controlled Drug Delivery

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available Recent pharmaceutical research has focused on controlled drug delivery having an advantage over conventional methods. Adequate controlled plasma drug levels, reduced side effects as well as improved patient compliance are some of the benefits that these systems may offer. Controlled delivery systems that can provide zero-order drug delivery have the potential for maximizing efficacy while minimizing dose frequency and toxicity. Thus, zero-order drug release is ideal in a large area of drug delivery which has therefore led to the development of various technologies with such drug release patterns. Systems such as multilayered tablets and other geometrically altered devices have been created to perform this function. One of the principles of multilayered tablets involves creating a constant surface area for release. Polymeric materials play an important role in the functioning of these systems. Technologies developed to date include among others: Geomatrix® multilayered tablets, which utilizes specific polymers that may act as barriers to control drug release; Procise®, which has a core with an aperture that can be modified to achieve various types of drug release; core-in-cup tablets, where the core matrix is coated on one surface while the circumference forms a cup around it; donut-shaped devices, which possess a centrally-placed aperture hole and Dome Matrix® as well as “release modules assemblage”, which can offer alternating drug release patterns. This review discusses the novel altered geometric system technologies that have been developed to provide controlled drug release, also focusing on polymers that have been employed in such developments.

    In an effort to regulate physician conflicts of interest, some US academic medical centers (AMCs) enacted policies restricting pharmaceutical representative sales visits to physicians (known as detailing) between 2006 and 2012. Little is known about the effect of these policies on physician prescribing. To analyze the association between detailing policies enacted at AMCs and physician prescribing of actively detailed and not detailed drugs. The study used a difference-in-differences multivariable regression analysis to compare changes in prescribing by physicians before and after implementation of detailing policies at AMCs in 5 states (California, Illinois, Massachusetts, Pennsylvania, and New York) that made up the intervention group with changes in prescribing by a matched control group of similar physicians not subject to a detailing policy. Academic medical center implementation of policies regulating pharmaceutical salesperson visits to attending physicians. The monthly within-drug class market share of prescriptions written by an individual physician for detailed and nondetailed drugs in 8 drug classes (lipid-lowering drugs, gastroesophageal reflux disease drugs, diabetes drugs, antihypertensive drugs, hypnotic drugs approved for the treatment of insomnia [sleep aids], attention-deficit/hyperactivity disorder drugs, antidepressant drugs, and antipsychotic drugs) comparing the 10- to 36-month period before implementation of the detailing policies with the 12- to 36-month period after implementation, depending on data availability. The analysis included 16 121 483 prescriptions written between January 2006 and June 2012 by 2126 attending physicians at the 19 intervention group AMCs and by 24 593 matched control group physicians. The sample mean market share at the physician-drug-month level for detailed and nondetailed drugs prior to enactment of policies was 19.3% and 14.2%, respectively. Exposure to an AMC detailing policy was associated with a

    Purpose We examined the influence of tobacco control program funding, smoke-free air laws, and cigarette prices on young adult smoking outcomes. Methods We use a natural experimental design approach that uses the variation in tobacco control policies across states and over time to understand their influence on tobacco outcomes. We combine individual outcome data with annual state-level policy data to conduct multivariable logistic regression models, controlling for an extensive set of sociodemographic factors. The participants are 18- to 25-year-olds from the 2002–2009 National Surveys on Drug Use and Health. The three main outcomes are past-year smoking initiation, and current and established smoking. A current smoker was one who had smoked on at least 1 day in the past 30 days. An established smoker was one who had smoked 1 or more cigarettes in the past 30 days and smoked at least 100 cigarettes in his or her lifetime. Results Higher levels of tobacco control program funding and greater smoke-free-air law coverage were both associated with declines in current and established smoking (p smoke-free air laws was associated with lower past year initiation with marginal significance (p = .058). Higher cigarette prices were not associated with smoking outcomes. Had smoke-free-air law coverage and cumulative tobacco control funding remained at 2002 levels, current and established smoking would have been 5%–7% higher in 2009. Conclusions Smoke-free air laws and state tobacco control programs are effective strategies for curbing young adult smoking. PMID:24268360

    Full Text Available The objective of this work was design, characterization, and optimization of controlled drug delivery system containing antibiotic drug/s. Osmotic drug delivery system was chosen as controlled drug delivery system. The porous osmotic pump tablets were designed using Plackett-Burman and Box-Behnken factorial design to find out the best formulation. For screening of three categories of polymers, six independent variables were chosen for Plackett-Burman design. Osmotic agent sodium chloride and microcrystalline cellulose, pore forming agent sodium lauryl sulphate and sucrose, and coating agent ethyl cellulose and cellulose acetate were chosen as independent variables. Optimization of osmotic tablets was done by Box-Behnken design by selecting three independent variables. Osmotic agent sodium chloride, pore forming agent sodium lauryl sulphate, and coating agent cellulose acetate were chosen as independent variables. The result of Plackett-Burman and Box-Behnken design and ANOVA studies revealed that osmotic agent and pore former had significant effect on the drug release up to 12 hr. The observed independent variables were found to be very close to predicted values of most satisfactory formulation which demonstrates the feasibility of the optimization procedure in successful development of porous osmotic pump tablets containing antibiotic drug/s by using sodium chloride, sodium lauryl sulphate, and cellulose acetate as key excipients.

  19. Beyond antidoping and harm minimisation: a stakeholder-corporate social responsibility approach to drug control for sport.

    Mazanov, Jason

    2016-04-01

    Debate about the ethics of drug control in sport has largely focused on arguing the relative merits of the existing antidoping policy or the adoption of a health-based harm minimisation approach. A number of ethical challenges arising from antidoping have been identified, and a number of, as yet, unanswered questions remain for the maturing ethics of applying harm minimisation principles to drug control for sport. This paper introduces a 'third approach' to the debate, examining some implications of applying a stakeholder theory of corporate social responsibility (CSR) to the issue of doping in sport. The introduction of the stakeholder-CSR model creates an opportunity to challenge the two dominant schools by enabling a different perspective to contribute to the development of an ethically robust drug control for sport.

    Agency is a pervasive feature of the health care market, with doctors acting as agents for both patients and the health care system. In a context of scarce resources, doctors are required to take opportunity cost into account when prescribing treatments, while cost containment policies cannot overlook their active role in determining health care resource allocation. This paper addresses this issue, investigating the effects of cost containment measures in the market of biosimilar drugs that represent a viable and cost-saving strategy for the reduction of health care expenditure. The analysis focuses on a particular region in Italy, where several timely policies to incentivize biosimilar prescribing were launched. Drugs were identified by the anatomical therapeutic chemical classification system. Information about biosimilar drugs and their originator biological products was extracted from the IMS Health regional database. Drug consumption was expressed in terms of counting units, while expenditure was evaluated in Euro (€). The market penetration of biosimilars was analyzed by year and quarterly. In the Campania region of Italy, the effects of cost containment policies, launched between 2009 and 2013, showed the prescription of biosimilars strongly increasing in 2010 until prescribing levels reached and exceeded the market share of the reference biological products in 2012. After a slight reduction, a plateau was observed at the beginning of 2013. At the same time, the use of the originator products had been decreasing until the first quarter of 2011. However, after a 1-year plateau, this trend was reversed, with a new increase in the consumption of the originators observed. Results show that the cost containment policies, applied to cut health expenditure "to cure and not to care", did not produce the cultural change necessary to make these policies effective in the long run. Therefore, top-down policies for cost containment are not successful; rather, a bottom

    Less targeted and limited solubility of hydrophobic-based drug are one of the serious obstacles in drug delivery system. Thus, new strategies to enhance the solubility of hydrophobic drug and controlled release behaviors would be developed. Herein, curcumin, a model of hydrophobic drug, has been loaded into PEGylated magnetic liposomes as a drug carrier platform for drug controlled release system. Inductive magnetic heating (hyperthermia)-stimulated drug release, in vitro cellular cytotoxicity assay of curcumin-loaded PEGylated magnetic liposomes and cellular internalization-induced by magnetic guidance would be investigated. The resultant of drug carriers could disperse homogeneously in aqueous solution, showing a superparamagnetic characteristic and could inductive magnetic heating with external high-frequency magnetic field (HFMF). In vitro curcumin release studies confirmed that the drug carriers exhibited no significant release at 37 °C, whereas exhibited rapid releasing at 45 °C. However, it would display enormous (three times higher) curcumin releasing under the HFMF exposure, compared with that without HFMF exposure at 45 °C. In vitro cytotoxicity test shows that curcumin-loaded PEGylated magnetic liposomes could efficiently kill MCF-7 cells in parallel with increasing curcumin concentration. Fluorescence microscopy observed that these drug carriers could internalize efficiently into the cellular compartment of MCF-7 cells. Thus, it would be anticipated that the novel hydrophobic drug-loaded PEGylated magnetic liposomes in combination with inductive magnetic heating are promising to apply in the combination of chemotherapy and thermotherapy for cancer therapy.

    MICROPARTICLES OFFER VARIOUS SIGNIFICANT ADVANTAGES AS DRUG DELIVERY SYSTEMS, INCLUDING: (i) an effective protection of the encapsulated active agent against (e.g. enzymatic) degradation, (ii) the possibility to accurately control the release rate of the incorporated drug over periods of hours to months, (iii) an easy administration (compared to alternative parenteral controlled release dosage forms, such as macro-sized implants), and (iv) Desired, pre-programmed drug release profiles can be provided which match the therapeutic needs of the patient. This article gives an overview on the general aspects and recent advances in drug-loaded microparticles to improve the efficiency of various medical treatments. An appropriately designed controlled release drug delivery system can be a foot ahead towards solving problems concerning to the targeting of drug to a specific organ or tissue, and controlling the rate of drug delivery to the target site. The development of oral controlled release systems has been a challenge to formulation scientist due to their inability to restrain and localize the system at targeted areas of gastrointestinal tract. Microparticulate drug delivery systems are an interesting and promising option when developing an oral controlled release system. The objective of this paper is to take a closer look at microparticles as drug delivery devices for increasing efficiency of drug delivery, improving the release profile and drug targeting. In order to appreciate the application possibilities of microcapsules in drug delivery, some fundamental aspects are briefly reviewed.

    The purpose of this thesis is to suggest a coherent, credible, and long-term counterterrorism policy in Colombia. The events of September 11, 2001 heightened U.S. awareness of Colombian terrorist organizations, the most powerful being the Revolutionary Armed Forces of Colombia (FARC). The U.S. counterterror approach in Colombia appears fragmented, with only minor changes to its previous drug control policies. In contrast, the Colombian government has developed and implemented a policy to ...

  4. Urban stormwater source control policies: why and how?

    Full Text Available Stormwater source control is becoming a common strategy for urban stormwater management in many countries. It relies on regulations or other policy instruments compelling or inciting implementation, for each new urban development, of small-scale facilities to locally store and manage stormwater. Local authorities that pioneered source control since the 1980s have already observed that small-scale facilities systematically implemented over a catchment are able to influence its hydrological behaviour. This capability is the main strength of source control, as it allows compensation for the negative effects of urbanization. Yet, it also represents its main risk: if initial decision-making is not sufficiently accurate, source control can produce long-term negative effects. Because of its current spreading, source control will acquire an increasing role as a driver of hydrological changes in urban catchments, and the directions of these changes depend on current policy-making practices. This paper presents an analysis and a critical discussion of the main objectives that policy-makers attribute to stormwater source control. The investigation is based on a sample of French case studies, completed by a literature review for international comparison. It identifies four main objectives, some typical of urban stormwater management and some more innovative: flood reduction, receiving waters protection, sustainable development, costs reduction. The discussion focuses on how current policy-making practices are able to translate these objectives in concrete policy instruments, and on which knowledge and tools could improve this process. It is shown that for some objectives, basic knowledge is available, but the creation of policy instruments which are effective at the catchment scale and adapted to local conditions is still problematic. For other objectives, substantial lacks of knowledge exist, casting doubts on long-term effectiveness of current policy

    The interest of this paper is to develop a general and systematic robust control methodology for active vibration control of flexible structures. For this purpose, first phase and gain control policies are proposed to impose qualitative frequency-dependent requirements on the controller to consider a complete set of control objectives. Then the proposed control methodology is developed by employing phase and gain control policies in the dynamic output feedback H ∞  control: according to the set of control objectives, phase and gain control policies incorporate necessary weighting functions and determine them in a rational and systematic way; on the other hand, with the appropriate weighting functions efficient H ∞  control algorithms can automatically realize phase and gain control policies and generate a satisfactory H ∞  controller. The proposed control methodology can be used for both SISO and MIMO systems with collocated or non-collocated sensors and actuators. In this paper, it is validated on a non-collocated piezoelectric cantilever beam. Both numerical simulations and experimental results demonstrate the effectiveness of the proposed control methodology. (paper)

    Much of the research used to support the ratification of the WHO Framework Convention on Tobacco Control (FCTC) was conducted in high-income countries or in highly controlled environments. Therefore, for the global tobacco control community to make informed decisions that will continue to effectively inform policy implementation, it is critical that the tobacco control community, policy makers, and funders have updated information on the state of the science as it pertains to provisions of the FCTC. Following the National Cancer Institute's process model used in identifying the research needs of the U.S. Food and Drug Administration's relatively new tobacco law, a core team of scientists from the Society for Research on Nicotine and Tobacco identified and commissioned internationally recognized scientific experts on the topics covered within the FCTC. These experts analyzed the relevant sections of the FCTC and identified critical gaps in research that is needed to inform policy and practice requirements of the FCTC. This paper summarizes the process and the common themes from the experts' recommendations about the research and related infrastructural needs. Research priorities in common across Articles include improving surveillance, fostering research communication/collaboration across organizations and across countries, and tracking tobacco industry activities. In addition, expanding research relevant to low- and middle-income countries (LMIC), was also identified as a priority, including identification of what existing research findings are transferable, what new country-specific data are needed, and the infrastructure needed to implement and disseminate research so as to inform policy in LMIC.

    Since the 1970s, media frenzies about drug addiction have focused mainly on illicit drugs taken by rebellious or marginalised addicts, relegating iatrogenic drug abuse, and policies and problems linked to psychotropic pharmaceuticals available by prescription or over-the-counter to the shadows. In this article I go beyond the division between illicit drugs and medicines still configuring both public representations and historiography: using archival materials from the 1960s-1990s in France, I highlight some blind spots in drug history. Firstly I demonstrate the role of pharmaceutical abuse in the career of addicts, and then examine regulation policies, which are the dark side, however complementary, of drug policies and prohibition. Finally, I analyse the role of physicians and pharmacists in this control, and discuss the various professional debates relating to the legal supply of psychoactive drugs. In all these issues, the frame of the Cold War context will also be highlighted.

    Canada is strongly influenced by US cross-border direct-to-consumer advertising (DTCA) and has held consultations to discuss introduction of DTCA since 1996. This article describes a survey of Canadian drug policy experts carried out in 2001, during one such legislative review. The survey results are compared to more recent DTCA policy developments. We recruited key informants on pharmaceutical policy to complete a faxed questionnaire that queried their opinions on DTCA information quality, effects on drug and health care use, and regulatory issues. Respondents were asked about the evidence they had used to back their opinions. Analysis was descriptive. Of 79 identified potential participants, 60 (76%) participated, 40% of whom were from federal and provincial government; 3% were private insurers; 18%, 15%, and 8% were from health professional groups, consumer groups, and patient groups, respectively; 8% and 7% were from pharmaceutical and advertising industries, respectively. Opinions were highly polarized on the effects of DTCA on drug and health care use. Advertising and pharmaceutical industry respondents were generally positive, public sector, health professional and consumer groups generally negative. Over 80% believed DTCA leads to higher private and public drug costs and more frequent physician visits. Fewer judged billboards or television to be appropriate media for DTCA than magazines or the Internet, and most believed that children and adolescents should not be targeted. Given the polarization observed within this survey, we examined how DTCA policy has evolved in Canada since 2001. The federal government has legislative authority over DTCA, but bears few of the additional costs potentially incurred through policy change. These fall to the provinces, which provide an eroding patchwork of public coverage for prescription drugs in the face of rapidly increasing costs. No new federal legislation has been tabled since 2001. However, considerable shifts in

    This paper investigates the discourses and policies on narcotics in Republic of Korea from 1945 to 1960. Since the Liberation the narcotic problem was regarded as the vestige of Japanese imperialism. which was expected to be cleaned up. The image of narcotic crimes as the legacy of the colonial past was turned into as the result of the Red Army's tactics to attack on the liberalist camp around the Korean war. The government of ROK represented the source of the illegal drugs as the Red army and the spy from North Korea. The anticommunist discourse about narcotics described the spies, who introduced the enormous amount of poppies into ROK and brought about the addicts, as the social evil. Through this discourse on poppies from North Korea, the government of ROK emphasized the immorality of the communists reinforcing the anticommunist regime, which was inevitable for the government of ROK to legitimize the division of Korea and the establishment of the government alone. This paper examines how the discourses and policies on narcotics in ROK was shaped and transformed from 1945 to 1960 focusing the relationship between the them and the political context such as anticommunism, Korean war, the division of Korea, and etc. This approach would be helpful to reveal the effect of the ROK's own political situation to the public health system involving the management for drugs.

    Drug-resistant tuberculosis (TB) is an occupational hazard for health-care workers (HCWs) in South Africa. We undertook this qualitative study to contextualize epidemiological findings suggesting that HCWs' elevated risk of drug-resistant TB is related to workplace exposure. A total of 55 HCWs and 7 hospital managers participated in focus groups and interviews about infection control (IC). Participants discussed caring for patients with drug-resistant TB, IC measures, occupational health programs, also stigma and support in the workplace. Key themes included: (i) lack of resources that hinders IC, (ii) distrust of IC efforts among HCWs, and (iii) disproportionate focus on individual-level personal protections, particularly N95 masks. IC programs should be evaluated, and the impact of new policies to rapidly diagnose drug-resistant TB and decentralize treatment should be assessed as part of the effort to control drug-resistant TB and create a safe workplace.

    In 2013, illegal drug use was responsible for 1.8% of years of life lost in the European Union, alcohol was responsible for 8.2% and tobacco for 18.2%, imposing economic burdens in excess of 2.5% of GDP. No single European country has optimal governance structures for reducing the harm done by nicotine, illegal drugs and alcohol, and existing ones are poorly designed, fragmented, and sometimes cause harm. Reporting the main science and policy conclusions of a transdisciplinary five-year analysis of the place of addictions in Europe, researchers from 67 scientific institutions addressed these problems by reframing an understanding of addictions.  A new paradigm needs to account for evolutionary evidence which suggests that humans are biologically predisposed to seek out drugs, and that, today, individuals face availability of high drug doses, consequently increasing the risk of harm.  New definitions need to acknowledge that the defining element of addictive drugs is 'heavy use over time', a concept that could replace the diagnostic artefact captured by the clinical term 'substance use disorder', thus opening the door for new substances to be considered such as sugar. Tools of quantitative risk assessment that recognize drugs as toxins could be further deployed to assess regulatory approaches to reducing harm. Re-designed governance of drugs requires embedding policy within a comprehensive societal well-being frame that encompasses a range of domains of well-being, including quality of life, material living conditions and sustainability over time; such a frame adds arguments to the inappropriateness of policies that criminalize individuals for using drugs and that continue to categorize certain drugs as illegal. A health footprint, modelled on the carbon footprint, and using quantitative measures such as years of life lost due to death or disability, could serve as the accountability tool that apportions responsibility for who and what causes drug-related harm.

    The Food and Drug Administration Modernization Act (FDAMA) of 1997, Best Pharmaceuticals for Children Act (BPCA) of 2002 and Pediatric Research Equity Act of 2007 provide an extended period of 6 months of marketing exclusivity (i.e. patent extension) to prescription drug manufacturers that conduct paediatric studies. Branded drugs in the statin, ACE inhibitor and selective serotonin reuptake inhibitor (SSRI) classes were three of many classes with drugs granted patent extensions. We estimated the cost impact of the 6-month exclusivity extension policy on the Utah Medicaid drug programme by comparing actual costs to projected costs had the 6-month exclusivity extension not been granted for these drugs and thus less expensive generic alternatives been available sooner. Using these results, we then projected the cost impact of this policy on Medicaid programmes in the US during the 18 months following patent expiration. The Utah Medicaid prescription claims obtained for statins, ACE inhibitors and SSRIs included reimbursement amount, number of units dispensed, days supplied, date of service and drug strength. Actual expenditures for each drug were calculated for the 6 months before and 12 months after generic availability. The percentage difference between the brand name prescription reimbursement amount to Medicaid in the last 2 months of the 6-month extension and the generic prescription reimbursement amount to Medicaid in the first 2 months following exclusivity expiration was then calculated for each drug. This was done using data from the 5 months surrounding the exclusivity expiration by regressing the log-transformed Utah Medicaid reimbursement amount on an indicator for patent expiration, controlling for number of units, volume of sales, month filled and strength. This was used to estimate what the initial generic prescription price would have been without the 6-month patent extension and what costs would have been in the 18 months following the original

    Kim, Yang-Hee; Tabata, Yasuhiko

    2015-11-01

    Controlled release systems have been noted to allow drugs to enhance their ability for bone regeneration. To this end, various biomaterials have been used as the release carriers of drugs, such as low-molecular-weight drugs, growth factors, and others. The drugs are released from the release carriers in a controlled fashion to maintain their actions for a long time period. Most research has been focused on the controlled release of single drugs to demonstrate the therapeutic feasibility. Controlled release of two combined drugs, so-called dual release systems, are promising and important for tissue regeneration. This is because the tissue regeneration process of bone formation is generally achieved by multiple bioactive molecules, which are produced from cells by other molecules. If two types of bioactive molecules, (i.e., drugs), are supplied in an appropriate fashion, the regeneration process of living bodies will be efficiently promoted. This review focuses on the bone regeneration induced by dual-controlled release of drugs. In this paper, various dual-controlled release systems of drugs aiming at bone regeneration are overviewed explaining the type of drugs and their release materials. Copyright © 2015 Elsevier B.V.

    The proportion of total healthcare expenditures spent on drugs has continued to grow in countries of all income categories. Policy-makers are under pressure to control pharmaceutical expenditures without adversely affecting quality of care. Financial incentives seeking to influence prescribers' behaviour include budgetary arrangements at primary care and hospital settings (pharmaceutical budget caps or targets), financial rewards for target behaviours or outcomes (pay for performance interventions) and reduced benefit margin for prescribers based on medicine sales and prescriptions (pharmaceutical reimbursement rate reduction policies). This is the first update of the original version of this review. To determine the effects of pharmaceutical policies using financial incentives to influence prescribers' practices on drug use, healthcare utilisation, health outcomes and costs (expenditures). We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (searched 29/01/2015); MEDLINE, Ovid SP (searched 29/01/2015); EMBASE, Ovid SP (searched 29/01/2015); International Network for Rational Use of Drugs (INRUD) Bibliography (searched 29/01/2015); National Health Service (NHS) Economic Evaluation Database (searched 29/01/2015); EconLit - ProQuest (searched 02/02/2015); and Science Citation Index and Social Sciences Citation Index, Institute for Scientific Information (ISI) Web of Knowledge (citation search for included studies searched 10/02/2015). We screened the reference lists of relevant reports and contacted study authors and organisations to identify additional studies. We included policies that intend to affect prescribing by means of financial incentives for prescribers. Included in this category are pharmaceutical budget caps or targets, pay for performance and drug reimbursement rate reductions and other financial policies, if they were specifically targeted at prescribing or drug utilisation. Policies in this review were defined as laws, rules

    Full Text Available Abstract Background This article seeks to identify the role of databases in health policy. Access to information and communication technologies has changed traditional relationships between the state and professionals, creating new systems of surveillance and control. As a result, databases may have a profound effect on controlling clinical practice. Methods We conducted three case studies to reconstruct the development and use of databases as policy instruments. Each database was intended to be employed to control the use of one particular pharmaceutical in the Netherlands (growth hormone, antiretroviral drugs for HIV and Taxol, respectively. We studied the archives of the Dutch Health Insurance Board, conducted in-depth interviews with key informants and organized two focus groups, all focused on the use of databases both in policy circles and in clinical practice. Results Our results demonstrate that policy makers hardly used the databases, neither for cost control nor for quality assurance. Further analysis revealed that these databases facilitated self-regulation and quality assurance by (national bodies of professionals, resulting in restrictive prescription behavior amongst physicians. Conclusion The databases fulfill control functions that were formerly located within the policy realm. The databases facilitate collaboration between policy makers and physicians, since they enable quality assurance by professionals. Delegating regulatory authority downwards into a network of physicians who control the use of pharmaceuticals seems to be a good alternative for centralized control on the basis of monitoring data.

    Prescription drug samples, as used by the pharmaceutical industry to market their products, are of current interest because of their influence on prescribing, and their potential impact on consumer safety. Very little research has been conducted into the use and misuse of prescription drug samples, and the influence of samples on health policies designed to improve the rational use of medicines. This is a topical issue in the prescription drug debate, with increasing costs and increasing concerns about optimizing use of medicines. This manuscript critically evaluates the research that has been conducted to date about prescription drug samples, discusses the issues raised in the context of traditional marketing theory, and suggests possible alternatives for the future.

    Characterizations of the drug release from microsphere and hydrogel preparation made from biodegradable polymers were investigated aiming at development of a drug delivery system which allows an optimum drug delivery and the identification of the factors which control its delivery. Poly-lactic acid microspheres containing 10% of progesterone were produced from poly DL-lactic acid and exposed to γ-ray at 5-1000 kGy. And its glass transition temperature (Tg) was determined by differential scanning calorimetry. The temperature was gradually lowered with an increase in the dose of radiation. Tg of the microsphere exposed at 1000 kGy was lower by 10degC compared with the untreated one, showing that Tg control is possible without changing the size distribution of microsphere. Then, the amount of progesterone released from microsphere was determined. The release rate of the drug linearly increased with a square root of radiation time. These results indicate that the control of drug release rate is possible through controling the microsphere's Tg by γ-ray radiation. (M.N.)

    NAPAP is examining a number of potential ways to reduce the precursors (sulfur dioxide and nitrogen oxides) to acid deposition. However, the policies to reduce acid deposition will have other physical, biological and economic effects unrelated to acid deposition. For example, control policies that reduce sulfur dioxide emissions may also increase visibility. The effects of an acid deposition policy that are unrelated to acid deposition are referred to as ''ancillary'' effects. This reserch identifies and characterizes the principle physical and economic ancillary effects associated with acid deposition control and mitigation policies. In this study the ancillary benefits associated with four specific acid deposition policy options were investigated. The four policy options investigated are: (1) flue gas desulfurization, (2) coal blending or switching, (3) reductions in automobile emissions of NO/sub x/, and (4) lake liming. Potential ancillary benefits of each option were identified and characterized. Particular attention was paid to the literature on economic valuation of potential ancillary effects.

    Depan, D.; Misra, R.D.K.

    2012-01-01

    We describe here a transformative approach to synthesize a hybrid nanostructured drug carrier that exhibits the characteristics of controlled drug release. The synthesis of the nanohybrid architecture involved two steps. The first step involved direct crystallization of biocompatible copolymer along the long axis of the carbon nanotubes (CNTs), followed by the second step of attachment of drug molecule to the polymer via hydrogen bonding. The extraordinary inorganic–organic hybrid architecture exhibited high drug loading ability and is physically stable even under extreme conditions of acidic media and ultrasonic irradiation. The temperature and pH sensitive characteristics of the hybrid drug carrier and high drug loading ability merit its consideration as a promising carrier and utilization of the fundamental aspects used for synthesis of other promising drug carriers. The higher drug release response during the application of ultrasonic frequency is ascribed to a cavitation-type process in which the acoustic bubbles nucleate and collapse releasing the drug. Furthermore, the study underscores the potential of uniquely combining CNTs and biopolymers for drug delivery. - Graphical abstract: Block-copolymer crystallized on carbon nanotubes (CNTs). Nanohybrid drug carrier synthesized by attaching doxorubicin (DOX) to polymer crystallized CNTs. Crystallized polymer on CNTs provide mechanical stability. Triggered release of DOX. Highlights: ► The novel synthesis of a hybrid nanostructured drug carrier is described. ► The drug carrier exhibits high drug loading ability and is physically stable. ► The high drug release is ascribed to a cavitation-type process.

  10. Microchips and controlled-release drug reservoirs.

    Staples, Mark

    2010-01-01

    This review summarizes and updates the development of implantable microchip-containing devices that control dosing from drug reservoirs integrated with the devices. As the expense and risk of new drug development continues to increase, technologies that make the best use of existing therapeutics may add significant value. Trends of future medical care that may require advanced drug delivery systems include individualized therapy and the capability to automate drug delivery. Implantable drug delivery devices that promise to address these anticipated needs have been constructed in a variety of ways using micro- and nanoelectromechanical systems (MEMS or NEMS)-based technology. These devices expand treatment options for addressing unmet medical needs related to dosing. Within the last few years, advances in several technologies (MEMS or NEMS fabrication, materials science, polymer chemistry, and data management) have converged to enable the construction of miniaturized implantable devices for controlled delivery of therapeutic agents from one or more reservoirs. Suboptimal performance of conventional dosing methods in terms of safety, efficacy, pain, or convenience can be improved with advanced delivery devices. Microchip-based implantable drug delivery devices allow localized delivery by direct placement of the device at the treatment site, delivery on demand (emergency administration, pulsatile, or adjustable continuous dosing), programmable dosing cycles, automated delivery of multiple drugs, and dosing in response to physiological and diagnostic feedback. In addition, innovative drug-medical device combinations may protect labile active ingredients within hermetically sealed reservoirs. Copyright (c) 2010 John Wiley & Sons, Inc.

    In order to recycle and dispose of all people's expired drugs, the government should design a subsidy policy to stimulate users to return their expired drugs, and drug-stores should take the responsibility of recycling expired drugs, in other words, to be recycling stations. For this purpose it is necessary for the government to select the right recycling stations and treatment stations to optimize the expired drug recycling logistics network and minimize the total costs of recycling and disposal. This paper establishes a tri-level programming model to study how the government can optimize an expired drug recycling logistics network and the appropriate subsidy policies. Furthermore, a Hybrid Genetic Simulated Annealing Algorithm (HGSAA) is proposed to search for the optimal solution of the model. An experiment is discussed to illustrate the good quality of the recycling logistics network and government subsides obtained by the HGSAA. The HGSAA is proven to have the ability to converge on the global optimal solution, and to act as an effective algorithm for solving the optimization problem of expired drug recycling logistics network and government subsidies.

    Policymakers and researchers seek answers to how liberalized drug policies affect people who inject drugs (PWID). In response to concerns about the failing "war on drugs," Mexico recently implemented drug policy reforms that partially decriminalized possession of small amounts of drugs for personal use while promoting drug treatment. Recognizing important epidemiologic, policy, and socioeconomic differences between the United States-where possession of any psychoactive drugs without a prescription remains illegal-and Mexico-where possession of small quantities for personal use was partially decriminalized, we sought to assess changes over time in knowledge, attitudes, behaviors, and infectious disease profiles among PWID in the adjacent border cities of San Diego, CA, USA, and Tijuana, Baja California, Mexico. Based on extensive binational experience and collaboration, from 2012-2014 we initiated two parallel, prospective, mixed methods studies: Proyecto El Cuete IV in Tijuana (n = 785) and the STAHR II Study in San Diego (n = 575). Methods for sampling, recruitment, and data collection were designed to be compatible in both studies. All participants completed quantitative behavioral and geographic assessments and serological testing (HIV in both studies; hepatitis C virus and tuberculosis in STAHR II) at baseline and four semi-annual follow-up visits. Between follow-up assessment visits, subsets of participants completed qualitative interviews to explore contextual factors relating to study aims and other emergent phenomena. Planned analyses include descriptive and inferential statistics for quantitative data, content analysis and other mixed-methods approaches for qualitative data, and phylogenetic analysis of HIV-positive samples to understand cross-border transmission dynamics. Investigators and research staff shared preliminary findings across studies to provide feedback on instruments and insights regarding local phenomena. As a result, recruitment and data

    Youth drug use is a significant at-risk youth behaviour and remains as one of the top priorities for mental health services, researchers and policy planners. The ecological characteristics of secondary school students' behaviour in Hong Kong are understudied. To examine individual, familial, social and environmental correlates of drug use among secondary students in Hong Kong. Data were extracted from a school survey with 3078 students. Among the 3078 students, 86 students reported to have used drugs in the past 6 months. A total of 86 age- and gender-matched controls with no drug-use behaviour in the past 6 months were randomly selected from the remaining students. Multiple logistic analysis was used to examine differential correlates between those who used and did not use substance in the past 6 months. Positive school experience and perspective to school and parental support are protective factors of drug use. Lower self-esteem, lower self-efficacy against using drugs and higher level of permissive attitude towards drugs were associated with drug use. Students who were low in self-esteem and rather impulsive tend to use drugs. To prevent students from drug use, efforts in individual, family, school and community-levels should be addressed. © The Author(s) 2015.

    Malaria due to P. falciparum is the number one cause of morbidity and mortality in Uganda where it is highly endemic in 95% of the country. The use of efficacious and effective antimalarial medicines is one of the key strategies for malaria control. Until 2000, Chloroquine (CQ) was the first-line drug for treatment of uncomplicated malaria in Uganda. Due to progressive resistance to CQ and to a combination of CQ with Sulfadoxine-Pyrimethamine, Uganda in 2004 adopted the use of ACTs as first-line drug for treating uncomplicated malaria. A review of the drug policy change process and postimplementation reports highlight the importance of managing the policy change process, generating evidence for policy decisions and availability of adequate and predictable funding for effective policy roll-out. These and other lessons learnt can be used to guide countries that are considering anti-malarial drug change in future.

    2009-11-01

    The regulation of khat, one of the most recent psychoactive drugs to become a globally traded commodity, remains hotly contested within different producer and consumer countries. As regimes vary, it has been possible to compare khat policies in Africa, Europe and North America from different disciplinary perspectives. Field research was conducted in East Africa and Europe, using a combination of semistructured interviews, participant observation and the analysis of trade statistics. The research established the significance of khat for rural producers, regional economies, as a tax base and source of foreign exchange. At the same time, khat as a psychoactive substance is associated with health and public safety problems that in turn are met with often ill-informed legislative responses. Bans have in turn lead to the criminalisation of users and sellers and illegal drug markets. The empirical work from Africa provides a strong argument for promoting evidence-based approaches to khat regulation, harnessing the positive aspects of the khat economy to develop a control model that incorporates the voices and respects the needs of rural producers. Ultimately, the framework for khat may provide both a model and an opportunity for revising the international treaties governing the control of other plant psychoactive-based substances.

  18. Generic drug policy in Australia: a community pharmacy perspective

    Beecroft, Grahame

    2007-01-01

    This article provides a commentary, from a community pharmacy perspective, on the policy environment for the pharmacy sector in Australia, with a particular focus on present challenges arising from proposals to achieve substantial PBS cost savings from an anticipated surge of new generic drugs. Some $2 billion of medicines currently on the PBS will come off patent in the next 4 years. This growth comes from a low base where generics currently account for only 15% of the total PBS budget. Remuneration for PBS dispensing is fixed through five year agreements with the government, so trading terms on generics are important for the cross-subsidy of other dispensing activities and professional services. These trading terms (discounts provided by generics suppliers) have become part of the overall cost and revenue structure of pharmacies. Despite these arrangements, generic substitution rates in Australia are lower than in most comparable countries, which the government views as an opportunity to promote generic use. The future of generic drug supply via the PBS is important to allow consumers access to medications at the lowest possible price and to provide space for PBS listing of new and expensive drugs. But considerations of PBS reform need to take account of the role and viability of community pharmacy sector as provider of pharmaceuticals in a timely and efficient manner to Australian residents.

    2016-01-01

    Analysis of the timing of launches of 642 new drugs in 76 countries during 1983–2002 shows that patent and price regulation regimes strongly affect how quickly new drugs become commercially available in different countries. Price regulation delays launch, while longer and more extensive patent rights accelerate it. Health policy institutions and economic and demographic factors that make markets more profitable also speed up diffusion. The estimated effects are generally robust to controlling for endogeneity of policy regimes with country fixed effects and instrumental variables. The results highlight the important role of policy choices in driving the diffusion of new innovations.

  1. A dawning demand for a new cannabis policy: A study of Swedish online drug discussions.

    2014-07-01

    This study examines how online discussions on drug policy are formulating an oppositional cannabis discourse in an otherwise prohibitionist country like Sweden. The focus of the paper is to identify demands for an alternative cannabis policy as well as analysing how these demands are linked to governance. The empirical material is 56 discussion-threads from the online message-board Flashback Forum that were active during the first eight months of 2012. Discourse theory was used to locate the discourse, and governmentality theory was used to locate the political belonging of the discourse. On Flashback Forum demands for a new cannabis policy are articulated in opposition to Swedish prohibitionist discourse. The oppositional discourse is constructed around the nodal points cannabis, harm, state and freedom that fill legalisation/decriminalisation/liberalisation with meaning. The nodal points are surrounded by policy demands that get their meaning through the particular nodal. These demands originate from neo-liberal and welfarist political rationalities. Neo-liberal and welfarist demands are mixed, and participants are simultaneously asking for state and individual approaches to handle the cannabis issue. Swedish online discourse on cannabis widens the scope beyond the confines of drug policy to broader demands such as social justice, individual choice and increased welfare. These demands are not essentially linked together and many are politically contradictory. This is also significant for the discourse; it is not hegemonised by a political ideology. The discourse is negotiated between the neo-liberal version of an alternative policy demanding individual freedom, and the welfarist version demanding social responsibility. This implies the influence of the heritage from the social-democratic discourse, centred on state responsibility, which have been dominating Swedish politics in modern times. Consequently, this study refutes that the demand for a new cannabis

    This paper is aimed at critically assessing the extent to which Non-Communicable Disease NCD-related policies introduced in Bangladesh align with the World Health Organization's (WHO) 2013-2020 Action Plan for the Global Strategy for the Prevention and Control of NCDs. The authors reviewed all relevant policy documents introduced by the Government of Bangladesh since its independence in 1971. The literature review targeted scientific and grey literature documents involving internet-based search, and expert consultation and snowballing to identify relevant policy documents. Information was extracted from the documents using a specific matrix, mapping each document against the six objectives of the WHO 2013-2020 Action Plan for the Global Strategy for the Prevention and Control of NCDs. A total of 51 documents were identified. Seven (14%) were research and/or surveys, nine were on established policies (17%), while seventeen (33%) were on action programmes. Five (10%) were related to guidelines and thirteen (25%) were strategic planning documents from government and non-government agencies/institutes. The study covered documents produced by the Government of Bangladesh as well as those by quasi-government and non-government organizations irrespective of the extent to which the intended policies were implemented. The policy analysis findings suggest that although the government has initiated many NCD-related policies or programs, they lacked proper planning, implementation and monitoring. Consequently, Bangladesh over the years had little success in effectively addressing the growing burden of non-communicable diseases. It is imperative that future research critically assess the effectiveness of national NCD policies by monitoring their implementation and level of population coverage.

    Candida-associated denture stomatitis (CADS), caused by colonization and biofilm-formation of Candida species on denture surfaces, is a significant clinical concern. We show here that modification of conventional denture materials with functional groups can significantly increase drug binding capacity and control drug release rate of the resulting denture materials for potentially managing CADS. In our approach, poly(methyl methacrylate) (PMMA)-based denture resins were surface grafted with three kinds of polymers, poly(1-vinyl-2-pyrrolidinone) (PNVP), poly(methacrylic acid) (PMAA), and poly(2-hydroxyethyl methacrylate) (PHEMA), through plasma-initiated grafting polymerization. With a grafting yield as low as 2 wt%, the three classes of new functionalized denture materials showed significantly higher drug binding capacities toward miconazole, a widely used antifungal drug, than the original PMMA denture resin control, leading to sustained drug release and potent biofilm-controlling effects against Candida. Among the three classes of functionalized denture materials, PNVP-grafted resin provided the highest miconazole binding capability and the most powerful antifungal and biofilm-controlling activities. Drug binding mechanisms were studied. These results demonstrated the importance of specific interactions between drug molecules and functional groups on biomaterials, shedding lights on future design of CADS-managing denture materials and other related devices for controlled drug delivery.

    We presented a general overview of the health care system as well as the pricing and reimbursement environment in Croatia. In Croatia, most of the public funding for health care is collected from employers, through mandatory health care contributions for all the employed citizens. This contribution is a dedicated tax reserved for the health care system derived from employees' salaries. The rest of the public funds is mainly from taxes used by the Ministry of Finance to complement the overall health budget each year. The population is covered by a basic health insurance plan provided by statute and optional insurance, administered by the Croatian Health Insurance Fund. Reimbursement decisions are based on the Ordinance of Ministry of Health issued in 2013, which is an ordinance establishing the criteria for inclusion of medicinal products in the Croatian Health Insurance Fund basic and supplementary drug lists. A health technology assessment agency was established in 2007 as a legal, public, independent, nonprofit institution under the Act on Quality of Health Care. Budget impact analysis is obligatory, and cost-effectiveness analysis is beneficial. Two reimbursement lists exist: the basic (100% drug coverage) and the supplementary (co-payment from 10% to 90%) lists. The basic list covers both hospital and retail drugs. There is also a special drug list for expensive drugs (mainly hospital drugs). International reference pricing is also in place. List updates are done on an yearly basis. Real-world evidence can be required for health technology assessment as evidence for the budget impact models and cost-effective analysis; it is, however, not mandatory. Copyright © 2017.

    Public health policies must address multiple goals and complex community health needs. Recently, management control practices have emerged to provide a broader type of information for evaluating the effectiveness of healthcare policies, and relate activities and processes to multiple strategic outcomes. This study compares the effect of traditional and contemporary management control practices on the achievement of public health policies. It is also analyzed how two different uses of such practices (enabling vs. coercive) facilitate the achievement of public health policies. Relationships are explored using data collected from managers from public health agencies and public hospitals in Spain. The findings show that contemporary management control practices are more suitable than traditional practices to achieve public health policies. Furthermore, results show that public health policies are better achieved when managers use management control practices in an enabling way rather than in a coercive way.

    We presented a general overview of the health care system as well as the pricing and reimbursement environment in Poland. Poland aims to ensure proper access to safe and effective medicines while reducing patients' share in treatment costs. Nevertheless, the co-payment for pharmacotherapy is still high (more than 60%). The key policymaker and regulator in the system is the Ministry of Health, which is supported by the Polish Agency for Health Technology Assessment and Tariff System (Agencja Oceny Technologii Medycznych i Taryfikacji), responsible for evaluating applicant drugs, and the Economic Commission, responsible for negotiating the official sales prices and conditions for reimbursement with pharmaceutical companies (e.g., level of reimbursement and risk-sharing scheme agreements). The Agency for Health Technology Assessment and Tariff System dossier is obligatory for reimbursement application and includes the analysis of clinical effectiveness, economic analysis (with the threshold of quality-adjusted life-year established as no more than 3 times the gross domestic product per capita), and the analysis of budget impact. In Poland, only a positive list of reimbursed drugs is published and it is updated every 2 months. The following levels of reimbursement are in use: 100%, 70%, 50%, and lump sum (about €0.8).

    This article is part of the study 'Illicit Drug Use in Seven Latin American Countries and Canada: Critical Perspectives of Family and Familiars' (7LACC), which investigated four domains: protective and risk factors; preventive initiatives; treatment facilities; and laws and policies. The article presents a section of the results based on four items of the laws and policies domain--as perceived by the family and acquaintances of illicit drug users living in the community. Participants were recruited in urban primary health care units located in Western Rio de Janeiro (city), Brazil. This multi-method, cross-temporal study performed interviews with 100 adults (18 years of age or older), all cognitively healthy. Results and key conclusions included non-compliance with the fundamental principles of the Unique Health System Legislation / Law 8.080/90 and the erroneous implementation of laws and public policies on illicit drug.

    Brazilian drugs legislation has evolved from a prohibitionist system to a less repressive one in terms of drug users. The objective of this study was to identify the perception of relatives and acquaintances of drug users living in Ribeirão Preto, São Paulo, Brazil, about the country's laws and policies on drugs. Data collection was performed using a structured questionnaire. The sample consisted of 100 drug users' relatives or acquaintances, selected at a public health service. Respondents' relationships with the drug user were as follows: 31% friend, 23% sibling, 15% child and 7% spouse. Most users (78%) were men, with an average age of 26 years. Results confirm that national laws and policies have a direct effect on individuals' attitude and behaviors. There is a lack of trust in the police and a general perception that, despite recent chances that favor user rehabilitation, the laws on drugs do not respect users' human rights.

  14. Controlled drug delivery systems towards new frontiers in patient care

    Rossi, Filippo; Masi, Maurizio

    2016-01-01

    This book offers a state-of-the-art overview of controlled drug delivery systems, covering the most important innovative applications. The principles of controlled drug release and the mechanisms involved in controlled release are clearly explained. The various existing polymeric drug delivery systems are reviewed, and new frontiers in material design are examined in detail, covering a wide range of polymer modification techniques. The concluding chapter is a case study focusing on use of a drug-eluting stent. The book is designed to provide the reader with a complete understanding of the mechanisms and design of controlled drug delivery systems, and to this end includes numerous step-by-step tutorials. It illustrates how chemical engineers can advance medical care by designing polymeric delivery systems that achieve either temporal or spatial control of drug delivery and thus ensure more effective therapy that eliminates the potential for both under-and overdosing.

    Essential medicine policy is a successful global health policy to promote rational drug use. The aim of this study was to evaluate the impact of the National Essential Medicines Policy (NEMP) on the rational drug use in primary care institutions in Jiangsu Province of China. In this exploratory study, a multistage, stratified, random sampling was used to select 3400 prescriptions from 17 primary care institutions who implemented the NEMP before (Jan 2010) and after the implementation of the NEMP (Jan 2014). The analyses were performed in SPSS 18.0 and SPSS Clementine client. After the implementation of the NEMP, the percentage of prescribed EML (Essential Medicines List) drugs rose significantly, the average number of drugs per prescription and average cost per prescription were declined significantly, while the differences of the prescription proportion of antibiotics and injection were not statistically significant. BP (Back Propagation) neural network analysis showed that the average number of drugs per prescription, the number of using antibiotics and hormone, regional differences, size of institutions, sponsorship, financial income of institutions, doctor degree, outpatient and emergency visits person times were important factors affecting the prescription costs, among these the average number of drugs per prescription has the greatest effect. The NEMP can promote the rational use of drugs in some degree, but its role is limited. We should not focus only on the EML but also make comprehensive NEMP.

    To investigate behaviours related to four alcohol policy variables (policy-relevant behaviours) and demographic variables in relation to typical quantities of alcohol consumed on-premise in six International Alcohol Control study countries. General population surveys with drinkers using a comparable survey instrument and data analysed using path analysis in an overall model and for each country. typical quantities per occasion consumed on-premise; gender, age; years of education, prices paid, time of purchase, time to access alcohol and liking for alcohol advertisements. In the overall model younger people, males and those with fewer years of education consumed larger typical quantities. Overall lower prices paid, later time of purchase and liking for alcohol ads predicted consuming larger typical quantities; this was found in the high-income countries, less consistently in the high-middle-income countries and not in the low middle-income country. Three policy-relevant behaviours (prices paid, time of purchase, liking for alcohol ads) mediated the relationships between age, gender, education and consumption in high-income countries. International Alcohol Control survey data showed a relationship between policy-relevant behaviours and typical quantities consumed and support the likely effect of policy change (trading hours, price and restrictions on marketing) on heavier drinking. The path analysis also revealed policy-relevant behaviours were significant mediating variables between the effect of age, gender and educational status on consumption. However, this relationship is clearest in high-income countries. Further research is required to understand better how circumstances in low-middle-income countries impact effects of policies. © 2018 The Authors Drug and Alcohol Review published by John Wiley & Sons Australia, Ltd on behalf of Australasian Professional Society on Alcohol and other Drugs.

    Alm, Christopher; Wolf, Ruben; Posegga, Joachim

    Existing policy languages suffer from a limited ability of directly and elegantly expressing high-level access control principles such as history-based separation of duty [22], binding of duty [26], context constraints [24], Chinese wall properties [10], and obligations [20]. It is often difficult to extend a language in order to retrofit these features once required or it is necessary to use complicated and complex language constructs to express such concepts. The latter, however, is cumbersome and error-prone for humans dealing with policy administration.

  3. Off-policy reinforcement learning for H∞ control design.

    Luo, Biao; Wu, Huai-Ning; Huang, Tingwen

    2015-01-01

    The H∞ control design problem is considered for nonlinear systems with unknown internal system model. It is known that the nonlinear H∞ control problem can be transformed into solving the so-called Hamilton-Jacobi-Isaacs (HJI) equation, which is a nonlinear partial differential equation that is generally impossible to be solved analytically. Even worse, model-based approaches cannot be used for approximately solving HJI equation, when the accurate system model is unavailable or costly to obtain in practice. To overcome these difficulties, an off-policy reinforcement leaning (RL) method is introduced to learn the solution of HJI equation from real system data instead of mathematical system model, and its convergence is proved. In the off-policy RL method, the system data can be generated with arbitrary policies rather than the evaluating policy, which is extremely important and promising for practical systems. For implementation purpose, a neural network (NN)-based actor-critic structure is employed and a least-square NN weight update algorithm is derived based on the method of weighted residuals. Finally, the developed NN-based off-policy RL method is tested on a linear F16 aircraft plant, and further applied to a rotational/translational actuator system.

    Countries from Southern Africa have formed a Development Community (SADC) to stimulate common actions in several areas, among them illicit drugs combat. In this context, the goal of this qualitative study was to identify information and perception about the cooperation set up between Mozambique and other SADC members in combatting illicit drugs. Data were collected through semi-structured interviews with public employees developing actions directed at the implementation of the Protocol to Combat Drugs in SADC. After transcriptions, the interviews were analyzed by content analysis and resulted in the categories: "Mozambique as a drugs corridor", "Cooperation Initiatives on Drugs among African countries", "Cooperation Difficulties in Africa", "Problems in Protocol Implementation" and "Difficulties to implement a control policy". As a consequence, there is a need to review and update the policies and strategies in the drugs area, as they are not contextualized in the country's current reality.

    Effective control of processed food and medicines is crucial for the maintenance of public health. Issues of wholesomeness, quality, efficacy and safety are of paramount concern to both consumers and regulatory agencies alike. Laws and regulatory are put in in place to ensure minimum standards of practice by the various operators in the food and pharmaceutical sub-sectors, such as will guarantee that the regulated products (food, drugs, cosmetics, medical devices, chemicals and bottled water) they deal in satisfy all the parameters of quality, wholesomeness, efficacy and safety. National Agency for Food and Drug Administration and Control (NAFDAC) was established to enforce all relevant laws and regulations on food and drugs among other-regulated products. NAFDAC has put in place appropriate administrative structures and procedures in its efforts to fulfill its mandate. Finally, the agency is in the process of extending its regulatory and control activities to cover irradiated food products in order to safeguard public health

    Air pollution is one of the most serious environmental problems, and it is also the inevitable result of the extensive economic development mode. The matter of air pollution in Beijing is becoming more and more serious since 2010, which has a great impact on the normal social production, living and human health. These hazards have been highly valued by the whole society. More than 30 years have been pasted since controlling the air pollution and the system of policies was relatively complete. These policies have improved the quality of atmospheric and prevented environment further deterioration. The policies performance is not obvious. It is urgent trouble to improve policy performance. This paper analyzes the 103 policies text of air pollution control in Beijing, and researches status, history and problems, and put forward suggestions on policy improvement and innovation at last.

    Tissue engineering is often referred to as a three-pronged discipline, with each prong corresponding to 1) a 3D material matrix (scaffold), 2) drugs that act on molecular signaling, and 3) regenerative living cells. Herein we focus on reviewing advances in controlled release of drugs from tissue engineering platforms. This review addresses advances in hydrogels and porous scaffolds that are synthesized from natural materials and synthetic polymers for the purposes of controlled release in tissue engineering. We pay special attention to efforts to reduce the burst release effect and to provide sustained and long-term release. Finally, novel approaches to controlled release are described, including devices that allow for pulsatile and sequential delivery. In addition to recent advances, limitations of current approaches and areas of further research are discussed. Copyright © 2015 Elsevier B.V. All rights reserved.

    Policymaking in Vietnam has traditionally been the preserve of the political elite, not open to the scrutiny of those outside the Communist Party. This paper aims to analyse Vietnam's HIV policy development in order to describe and understand the policy content, policy-making processes, actors and obstacles to policy implementation. Nine policy documents on HIV were analysed and 17 key informant interviews were conducted in Hanoi and Quang Ninh Province, based on a predesigned interview guide. Framework analysis, a type of qualitative content analysis, was applied for data analysis. Our main finding was that during the last two decades, developments in HIV policy in Vietnam were driven in a top-down way by the state organs, with support and resources coming from international agencies. Four major themes were identified: HIV policy content, the policy-making processes, the actors involved and human resources for policy implementation. Vietnam's HIV policy has evolved from one focused on punitive control measures to a more rights-based approach, encompassing harm reduction and payment of health insurance for medical costs of patients with HIV-related illness. Low salaries and staff reluctance to work with patients, many of whom are drug users and female sex workers, were described as the main barriers to low health staff motivation. Health policy analysis approaches can be applied in a traditional one party state and can demonstrate how similar policy changes take place, as those found in pluralistic societies, but through more top-down and somewhat hidden processes. Enhanced participation of other actors, like civil society in the policy process, is likely to contribute to policy formulation and implementation that meets the diverse needs and concerns of its population.

    Although California communities have been relatively successful in adopting and implementing a wide range of local tobacco control policies, the process has not been without its setbacks and barriers. Little is known about local policy adoption, and this paper examines these processes related to adopting and implementing outdoor smoke-free policies, focusing on the major barriers faced by local-level tobacco control organizations in this process. Ninety-six projects funded by the California Tobacco Control Program submitted final evaluation reports pertaining to an outdoor smoking objective, and the reports from these projects were analyzed. The barriers were grouped in three primary areas: politically polarizing barriers, organizational barriers, and local political orientation. The barriers identified in this study underscore the need for an organized action plan in adopting local tobacco policy. The authors also suggest potential strategies to offset the barriers, including: (1) having a "champion" who helps to carry an objective forward; (2) tapping into a pool of youth volunteers; (3) collecting and using local data as a persuasive tool; (4) educating the community in smoke-free policy efforts; (5) working strategically within the local political climate; and (6) demonstrating to policymakers the constituent support for proposed policy.

  12. Osmotically driven drug delivery through remote-controlled magnetic nanocomposite membranes

    2015-09-29

    Implantable drug delivery systems can provide long-term reliability, controllability, and biocompatibility, and have been used in many applications, including cancer pain and non-malignant pain treatment. However, many of the available systems are limited to zero-order, inconsistent, or single burst event drug release. To address these limitations, we demonstrate prototypes of a remotely operated drug delivery device that offers controllability of drug release profiles, using osmotic pumping as a pressure source and magnetically triggered membranes as switchable on-demand valves. The membranes are made of either ethyl cellulose, or the proposed stronger cellulose acetate polymer, mixed with thermosensitive poly(N-isopropylacrylamide) hydrogel and superparamagnetic iron oxide particles. The prototype devices\\' drug diffusion rates are on the order of 0.5–2 μg/h for higher release rate designs, and 12–40 ng/h for lower release rates, with maximum release ratios of 4.2 and 3.2, respectively. The devices exhibit increased drug delivery rates with higher osmotic pumping rates or with magnetically increased membrane porosity. Furthermore, by vapor deposition of a cyanoacrylate layer, a drastic reduction of the drug delivery rate from micrograms down to tens of nanograms per hour is achieved. By utilizing magnetic membranes as the valve-control mechanism, triggered remotely by means of induction heating, the demonstrated drug delivery devices benefit from having the power source external to the system, eliminating the need for a battery. These designs multiply the potential approaches towards increasing the on-demand controllability and customizability of drug delivery profiles in the expanding field of implantable drug delivery systems, with the future possibility of remotely controlling the pressure source.

    Fletcher, Jason M.

    2012-01-01

    Background Research has shown that tobacco control policies have helped produce the dramatic decline in use over the decades following the 1964 surgeon general’s report. However, prevalence rates have stagnated during the past two decades in the US, even with large tobacco taxes and expansions of clean air laws. The observed differences in tobacco control policy effectiveness and why policies do not help all smokers are largely unexplained. Objective The aim of this study was to determine the importance of genetics in explaining response to tobacco taxation policy by testing the potential of gene-policy interaction in determining adult tobacco use. Methods A moderated regression analysis framework was used to test interactive effects between genotype and tobacco policy in predicting tobacco use. Cross sectional data of US adults from the National Health and Nutrition Examination Survey (NHANES) linked with genotype and geocodes were used to identify tobacco use phenotypes, state-level taxation rates, and variation in the nicotinic acetylcholine receptor (CHRNA6) genotype. Tobacco use phenotypes included current use, number of cigarettes smoked per day, and blood serum cotinine measurements. Results Variation in the nicotinic acetylcholine receptor was found to moderate the influence of tobacco taxation on multiple measures of tobacco use. Individuals with the protective G/G polymorphism (51% of the sample) responded to taxation while others had no response. The estimated differences in response by genotype were C/C genotype: b = −0.016 se  = 0.018; G/C genotype: b = 0.014 se  = 0.017; G/G genotype: b = −0.071 se 0.029. Conclusions This study provides novel evidence of “gene-policy” interaction and suggests a genetic mechanism for the large differences in response to tobacco policies. The inability for these policies to reduce use for individuals with specific genotypes suggests alternative methods may be needed to further reduce use

    The PID-control of drug delivery or the neuromuscular blockade (NMB) in closed-loop anesthesia is considered. The NMB system dynamics portrayed by a Wiener model can exhibit sustained nonlinear oscillations under realistic PID gains and for physiologically feasible values of the model parameters. Such oscillations, also repeatedly observed in clinical trials, lead to under- and over-dosing of the administered drug and undermine patient safety. This paper proposes a tuning policy for the proportional PID gain that via bifurcation analysis ensures oscillations-free performance of the control loop. Online estimates of the Wiener model parameters are needed for the controller implementation and monitoring of the closed-loop proximity to oscillation. The nonlinear dynamics of the PID-controlled NMB system are studied by bifurcation analysis. A database of patient models estimated under PID-controlled neuromuscular blockade during general anesthesia is utilized, along with the corresponding clinical measurements. The performance of three recursive algorithms is compared in the application at hand: an extended Kalman filter, a conventional particle filter (PF), and a PF making use of an orthonormal basis to estimate the probability density function from the particle set. It is shown that with a time-varying proportional PID gain, the type of equilibria of the closed-loop system remains the same as in the case of constant controller gains. The recovery time and frequency of oscillations are also evaluated in simulation over the database of patient models. Nonlinear identification techniques based on model linearization yield biased parameter estimates and thus introduce superfluous uncertainty. The bias and variance of the estimated models are related to the computational complexity of the identification algorithms, highlighting the superiority of the PFs in this safety-critical application. The study demonstrates feasibility of the proposed oscillation-free control

    In order to introduce the drug to the target organ, we developed a gel to control the drug releasing velocity by response to change of temperature by means of γ-ray irradiation to gelatin-GMA modified dextran mixture aqueous solution. A certain level of molecular weight of drug is necessary. The response to the temperature (change of drug releasing velocity) was affected by the concentration of gelatin and the modification rate of GMA. The Higuchi equation was applied to the releasing of β-galactosidase from gelatin-dextran gel and the releasing velocity was calculated. The releasing velocity decreased with increasing GMA modification rate at 37degC and 15degC. The releasing velocity of β-galactosidase decreased with increasing the concentration of gelatin at 15degC, but the velocity increased with increasing the concentration at 37degC. These results indicated that the good drug releasing conditions are obtained by controlling the GMA modification rate and the concentration of gelatin. (S.Y.)

    The administration of poorly bioavailable drug through parenteral route is regarded the most efficient for drug delivery. Parenteral delivery provides rapid onset even for the drug with narrow therapeutic window, but to maintain the systemic drug level repeated installation are required which cause the patient discomfort.

    2013-01-01

    Reducing greenhouse gas emissions is now an urgent priority. Systems control theory, and in particular feedback control, can be helpful in designing policies that achieve sustainable levels of emissions of CO 2 (and other greenhouse gases) while minimizing the impact on the economy, and at the same time explicitly addressing the high levels of uncertainty associated with predictions of future emissions. In this paper, we describe preliminary results for an approach where model predictive control (MPC) is applied to a model of the UK economy (UK 4see model) as a test bed to design sustainable policies for greenhouse gas emissions. Using feedback control, the policies are updated on the basis of the actual emissions, rather than on the predicted level of emissions. The basic structure and principle of the UK 4see model is described and its implementation in Simulink is presented. A linearized state space model is obtained and model predictive control is applied to design policies for CO 2 emissions. Simulation results are presented to demonstrate the effectiveness of the proposed method. The preliminary results obtained in this paper illustrate the strength of the proposed design approach and form the basis for future research on using systems control theory to design optimal sustainable policies

    There is little information on the extent to which African countries are addressing alcohol consumption and alcohol-related harm, which suggests that evaluations of national alcohol policies are needed in this region. The aim of this article is to examine the strength of a mix of national alcohol control policies in African countries, as well as the relationship between alcohol policy restrictiveness scores and adult alcohol per capita consumption (APC) among drinkers at the national level. We examined national alcohol policies of 46 African countries, as of 2012, in four regulatory categories (price, availability, marketing and drink-driving), and analyzed the restrictiveness of national alcohol policies using an adapted Alcohol Policy Index (API). To assess the validity of the policy restrictiveness scores, we conducted correlational analyses between policy restrictiveness scores and APC among drinkers in 40 countries. Countries attained a mean score of 44.1 of 100 points possible, ranging from 9.1 (Sao Tomé and Principe) to 75.0 (Algeria), with low scores indicating low policy restrictiveness. Policy restrictiveness scores were negatively correlated with and APC among drinkers (rs = -0.353, P = 0.005). There is great variation in the strength of alcohol control policies in countries throughout the African region. Tools for comparing the restrictiveness of alcohol policies across countries are available and are an important instrument to monitor alcohol policy developments. The negative correlation between policy restrictiveness and alcohol consumption among drinkers suggests the need for stronger alcohol policies as well as increased training and capacity building at the country level. © The Author 2015.

    The aim of this study was to fill the lack of knowledge regarding a more grounded exploration of the consumer's decision-making process in the context of generic drugs. In this perspective, a model, within the theoretical framework of the Theory of Planned Behaviour (TPB), for studying the consumers' purchase intention of generic drugs was developed. An online survey on 2,222 Italian people who bought drugs in the past was conducted. The proposed model was tested through structural equation modelling (SEM). Almost all the constructs considered in the model, except the perceived behavioural control, contribute to explain the consumer's purchase intention of generic drugs, after controlling for demographic variables (age, income, education). Specifically, attitude, subjective norm, past behaviour, self-identity and trust in the pharmacist have a positive influence on the intention to buy generic drugs. On the contrary, perceived risk towards products and brand sensitivity act negatively. The results of the present study could be useful to public policy makers in developing effective policies and educational campaigns aimed at promoting generic drugs. Specifically, marketing efforts should be directed to inform consumers about the generic drugs' characteristics to mitigate the perceived risk towards these products and to raise awareness during their decision-making process.

    The aim of this study was to describe trends in attitudes to alcohol control policies in Norway over a period of 50 years and to discuss how these trends relate to developments in alcohol policy. Survey data from 17 national population surveys, national statistics and previous publications were applied to describe trends in attitudes to alcohol control polices (access to alcohol and price) and changes in these policies over the period 1962 to 2012. From 1962 to 1999, an increasing proportion of the population reported that regulations on availability of alcohol were too strict and that alcohol prices were too high, whereas in the 2000s this trend was reversed and support for existing control policies increased. Although the pillars of Norwegian alcohol policy--high prices, restricted access and a state monopoly on retail sales-remained, control policies were gradually relaxed throughout the entire period. Relaxation of strict alcohol control policies in Norway in the first four decades were probably, in part, the result of increasingly liberal public opinion. The subsequent reversed trend in opinions with increasing support for control policies may be due to several factors, for example, consumer-oriented changes in the monopoly system, increased availability and affordability, increased awareness of alcohol-related harm and the effectiveness of control policies. Thus, the dynamics of policies and attitudes may well change over time. © 2013 Australasian Professional Society on Alcohol and other Drugs.

  3. The evolution of HIV policy in Vietnam: from punitive control measures to a more rights-based approach

    Full Text Available Aim: Policymaking in Vietnam has traditionally been the preserve of the political elite, not open to the scrutiny of those outside the Communist Party. This paper aims to analyse Vietnam's HIV policy development in order to describe and understand the policy content, policy-making processes, actors and obstacles to policy implementation. Methods: Nine policy documents on HIV were analysed and 17 key informant interviews were conducted in Hanoi and Quang Ninh Province, based on a predesigned interview guide. Framework analysis, a type of qualitative content analysis, was applied for data analysis. Results: Our main finding was that during the last two decades, developments in HIV policy in Vietnam were driven in a top-down way by the state organs, with support and resources coming from international agencies. Four major themes were identified: HIV policy content, the policy-making processes, the actors involved and human resources for policy implementation. Vietnam's HIV policy has evolved from one focused on punitive control measures to a more rights-based approach, encompassing harm reduction and payment of health insurance for medical costs of patients with HIV-related illness. Low salaries and staff reluctance to work with patients, many of whom are drug users and female sex workers, were described as the main barriers to low health staff motivation. Conclusion: Health policy analysis approaches can be applied in a traditional one party state and can demonstrate how similar policy changes take place, as those found in pluralistic societies, but through more top-down and somewhat hidden processes. Enhanced participation of other actors, like civil society in the policy process, is likely to contribute to policy formulation and implementation that meets the diverse needs and concerns of its population.

    The drug-related locus of control scale (DR-LOC) is a new instrument for assessing a person's belief of "being in control" in situations involving drug abuse. It consists of 16-item pairs presented in a forced-choice format, based on the conceptual model outlined by Rotter. The model characterizes the extent to which a person believes that the outcome of an event is under their personal control (internal locus of control) or the influence of external circumstances (external locus of control). A total of 592 volunteers completed the DR-LOC and the Rotter's I-E scale. Approximately half of the respondents were enrolled in a drug treatment program for opiates, stimulants and/or alcohol dependence (n = 282), and the remainder (n = 310) had no history of drug dependence. Factor analysis of DR-LOC items revealed 2 factors reflecting control beliefs regarding (i) the successful recovery from addiction, and (ii) decisions to use drugs. The extent to which a person attributes control in drug-related situations is significantly influenced by their personal or professional experiences with drug addiction. Drug-dependent individuals have a greater internal sense of control with regard to addiction recovery or drug-taking behaviors than health professionals and/or non-dependent control volunteers. The DR-LOC has shown to effectively translate generalized expectancies of control into a measure of control expectancies for drug-related situations, making it more sensitive for drug-dependent individuals than Rotter's I-E scale. Further research is needed to demonstrate its performance at discriminating between heterogeneous clinical groups such as between treatment-seeking versus non-treatment-seeking drug users.

    We examined the associations among school-based obesity policies, social capital, and adolescents' self-reported weight control behaviors, focusing on how the collective roles of community and adopted policies affect gender groups differently. We estimated state-level ecologic models using 1-way random effects seemingly unrelated regressions derived from panel data for 43 states from 1991 to 2009, which we obtained from the Centers for Disease Control and Prevention's Youth Risk Behavior Surveillance System. We used multiplicative interaction terms to assess how social capital moderates the effects of school-based obesity policies. School-based obesity policies in active communities were mixed in improving weight control behaviors. They increased both healthy and unhealthy weight control behaviors among boys but did not increase healthy weight control behaviors among girls. Social capital is an important contextual factor that conditions policy effectiveness in large contexts. Heterogeneous behavioral responses are associated with both school-based obesity policies and social capital. Building social capital and developing policy programs to balance outcomes for both gender groups may be challenging in managing childhood obesity.

  7. A remotely operated drug delivery system with dose control

    2017-05-08

    “On demand” implantable drug delivery systems can provide optimized treatments, due to their ability to provide targeted, flexible and precise dose release. However, two important issues that need to be carefully considered in a mature device include an effective actuation stimulus and a controllable dose release mechanism. This work focuses on remotely powering an implantable drug delivery system and providing a high degree of control over the released dose. This is accomplished by integration of a resonance-based wireless power transfer system, a constant voltage control circuit and an electrolytic pump. Upon the activation of the wireless power transfer system, the electrolytic actuator is remotely powered by a constant voltage regardless of movements of the device within an effective range of translation and rotation. This in turn contributes to a predictable dose release rate and greater flexibility in the positioning of external powering source. We have conducted proof-of-concept drug delivery studies using the liquid drug in reservoir approach and the solid drug in reservoir approach, respectively. Our experimental results demonstrate that the range of flow rate is mainly determined by the voltage controlled with a Zener diode and the resistance of the implantable device. The latter can be adjusted by connecting different resistors, providing control over the flow rate to meet different clinical needs. The flow rate can be maintained at a constant level within the effective movement range. When using a solid drug substitute with a low solubility, solvent blue 38, the dose release can be kept at 2.36μg/cycle within the effective movement range by using an input voltage of 10Vpp and a load of 1.5 kΩ, which indicates the feasibility and controllability of our system without any complicated closed-loop sensor.

    Full Text Available Although essentially not all therapies need drug intervention, drugs is still an important components in health sector, either in preventive, curative, rehabilitative or promotion efforts. Hence the access to drugs is a main problem, either in international or national scale even to the smallest unit. The problem on access to drugs is very complicated and cannot be separated especially from pharmacy management problems; moreover in general from the overall lack of policy development and effective of health policy, and also the implementation process. With the policy development and effective health policy, rational drug uses, sufficient health service budget so a country can overcome the health problems. Besides infrastructures, regulations, distribution and cultural influences; the main obstacles for drug access is drugs affordability if the price of drugs is an important part and determined by many factors, especially the drug status whether is still patent orgenerics that significantly decrease cost of health cares and enhance the drugs affordability. The determination of essential drug prices in developing countries should based on equity principal so that poor people pay cheaper and could afford the essential drugs. WHO predicts two third of world population can not afford the essential drugs in which in developing countries, some are because of in efficient budget allocation in consequence of drug distribution management, including incorrect selection and allocation and also irrational uses. In part these could be overcome by enhancing performances on the allocation pharmacy needs, including the management of information system, inventory management, stock management and the distribution. Key words: access, drugs, essential drugs, generic drugs

    The biopharmaceutical complexity of today's new drug candidates provides significant challenges for pharmaceutical scientists in terms of both candidate selection and optimizing subsequent development strategy. In addition, life cycle management of marketed drugs has become an important income stream for pharmaceutical companies, but the selection of least risk/highest benefit strategies is far from simple. The proactive adoption of human drug absorption (HDA) studies using remote controlled capsules offers the pharmaceutical scientist significant guidance for planning a route through the maze of product development. This review examines the position of HDA studies in drug development, using a variety of case histories and an insightful update on remote controlled capsules to achieve site-specific delivery.

    2007-01-01

    Full Text Available A novel admission control (AC policy is proposed for the uplink of a cellular CDMA beamforming system. An approximated power control feasibility condition (PCFC, required by a cross-layer AC policy, is derived. This approximation, however, increases outage probability in the physical layer. A truncated automatic retransmission request (ARQ scheme is then employed to mitigate the outage problem. In this paper, we investigate the joint design of an AC policy and an ARQ-based outage mitigation algorithm in a cross-layer context. This paper provides a framework for joint AC design among physical, data-link, and network layers. This enables multiple quality-of-service (QoS requirements to be more flexibly used to optimize system performance. Numerical examples show that by appropriately choosing ARQ parameters, the proposed AC policy can achieve a significant performance gain in terms of reduced outage probability and increased system throughput, while simultaneously guaranteeing all the QoS requirements.

    Full Text Available Biofilm infections are extremely hard to eradicate and controlled, triggered and controlled drug release properties may prolong drug release time. In this study, the ability to externally control drug release from micro and nanoparticles was investigated. We prepared micro/nanoparticles containing ciprofloxacin (CIP and magnetic nanoparticles encapsulated in poly (lactic-co-glycolic acid PLGA. Both micro/nanoparticles were observed to have narrow size distributions. We investigated and compared their passive and externally triggered drug release properties based on their different encapsulation structures for the nano and micro systems. In passive release studies, CIP demonstrated a fast rate of release in first 2 days which then slowed and sustained release for approximately 4 weeks. Significantly, magnetic nanoparticles containing systems all showed ability to have triggered drug release when exposed to an external oscillating magnetic field (OMF. An experiment where the OMF was turned on and off also confirmed the ability to control the drug release in a pulsatile manner. The magnetically triggered release resulted in a 2-fold drug release increase compared with normal passive release. To confirm drug integrity following release, the antibacterial activity of released drug was evaluated in Pseudomonas aeruginosa biofilms in vitro. CIP maintained its antimicrobial activity after encapsulation and triggered release.

    2008-12-01

    Microcapsules made of biopolymers are of both scientific and technological interest and have many potential applications in medicine, including their use as controlled drug delivery devices. The present study makes use of the electrostatic interaction between polycations and polyanions to form a multilayered microcapsule shell and also to control the loading and release of charged drug molecules inside the microcapsule. Micron-sized calcium carbonate (CaCO3) particles were synthesized and integrated with chondroitin sulfate (CS) through a reaction between sodium carbonate and calcium nitrate tetrahydrate solutions suspended with CS macromolecules. Oppositely charged biopolymers were alternately deposited onto the synthesized particles using electrostatic layer-by-layer self-assembly, and glutaraldehyde was introduced to cross-link the multilayered shell structure. Microcapsules integrated with CS inside the multilayered shells were obtained after decomposition of the CaCO3 templates. The integration of a matrix (i.e., CS) permitted the subsequent selective control of drug loading and release. The CS-integrated microcapsules were loaded with a model drug, bovine serum albumin labeled with fluorescein isothiocyanate (FITC-BSA), and it was shown that pH was an effective means of controlling the loading and release of FITC-BSA. Such CS-integrated microcapsules may be used for controlled localized drug delivery as biodegradable devices, which have advantages in reducing systemic side effects and increasing drug efficacy.

    Objective. When using an intracortical BCI (iBCI), users modulate their neural population activity to move an effector towards a target, stop accurately, and correct for movement errors. We call the rules that govern this modulation a ‘feedback control policy’. A better understanding of these policies may inform the design of higher-performing neural decoders. Approach. We studied how three participants in the BrainGate2 pilot clinical trial used an iBCI to control a cursor in a 2D target acquisition task. Participants used a velocity decoder with exponential smoothing dynamics. Through offline analyses, we characterized the users’ feedback control policies by modeling their neural activity as a function of cursor state and target position. We also tested whether users could adapt their policy to different decoder dynamics by varying the gain (speed scaling) and temporal smoothing parameters of the iBCI. Main results. We demonstrate that control policy assumptions made in previous studies do not fully describe the policies of our participants. To account for these discrepancies, we propose a new model that captures (1) how the user’s neural population activity gradually declines as the cursor approaches the target from afar, then decreases more sharply as the cursor comes into contact with the target, (2) how the user makes constant feedback corrections even when the cursor is on top of the target, and (3) how the user actively accounts for the cursor’s current velocity to avoid overshooting the target. Further, we show that users can adapt their control policy to decoder dynamics by attenuating neural modulation when the cursor gain is high and by damping the cursor velocity more strongly when the smoothing dynamics are high. Significance. Our control policy model may help to build better decoders, understand how neural activity varies during active iBCI control, and produce better simulations of closed-loop iBCI movements.

  19. International trade agreements challenge tobacco and alcohol control policies.

    Science.gov (United States)

    Zeigler, Donald W

    2006-11-01

    This report reviews aspects of trade agreements that challenge tobacco and alcohol control policies. Trade agreements reduce barriers, increase competition, lower prices and promote consumption. Conversely, tobacco and alcohol control measures seek to reduce access and consumption, raise prices and restrict advertising and promotion in order to reduce health and social problems. However, under current and pending international agreements, negotiated by trade experts without public health input, governments and corporations may challenge these protections as constraints on trade. Advocates must recognise the inherent conflicts between free trade and public health and work to exclude alcohol and tobacco from trade agreements. The Framework Convention on Tobacco Control has potential to protect tobacco policies and serve as a model for alcohol control.

    Numerous studies document the causal relationship between prenatal smoking and adverse maternal and child health (MCH) outcomes. Studies also reveal the impact that tobacco control policies have on prenatal smoking. The purpose of this study is to estimate the effect of tobacco control policies on prenatal smoking prevalence and adverse MCH outcomes. The US SimSmoke simulation model was extended to consider adverse MCH outcomes. The model estimates prenatal smoking prevalence and, applying standard attribution methods, uses estimates of MCH prevalence and relative smoking risks to estimate smoking-attributable MCH outcomes over time. The model then estimates the effect of tobacco control policies on adverse birth outcomes averted. Different tobacco control policies have varying impacts on the number of smoking-attributable adverse MCH birth outcomes. Higher cigarette taxes and comprehensive marketing bans individually have the biggest impact with a 5% to 10% reduction across all outcomes for the period from 2015 to 2065. The policies with the lowest impact (2%-3% decrease) during this period are cessation treatment, health warnings, and complete smoke-free laws. Combinations of all policies with each tax level lead to 23% to 28% decreases across all outcomes. Our findings demonstrate the substantial impact of strong tobacco control policies for preventing adverse MCH outcomes, including long-term health implications for children exposed to low birth weight and preterm birth. These benefits are often overlooked in discussions of tobacco control. © The Author 2015. Published by Oxford University Press on behalf of the Society for Research on Nicotine and Tobacco.

    The definition of a rare disease is not universal and depends on the legislation and policies adopted by each region or country. The main objective of this article is to describe and discuss the legal framework and the regulatory environment of orphan drugs worldwide. Some reflections and discussions on the need for specific orphan drug legislation or policies are described at length. Furthermore, some aspects of the history of each region in respect of the orphan drug legislation evolution are outlined. This article describes and compares the orphan drug legislation or policies of the following countries or regions: United Sates of America (US), European Union (EU), Japan, Australia, Singapore, Taiwan and Canada. The incentives described in the orphan drug legislations or policies, the criteria for designation of orphan status and the authorisation process of an orphan drug are also described and compared. The legislations and policies are to some extent similar but not the same. It is important to understand the main differences among all available legislative systems to improve the international collaboration in the field of orphan drugs and rare diseases.

  3. Policy reconciliation for access control in dynamic cross-enterprise collaborations

    Preuveneers, D.; Joosen, W.; Ilie-Zudor, E.

    2018-03-01

    In dynamic cross-enterprise collaborations, different enterprises form a - possibly temporary - business relationship. To integrate their business processes, enterprises may need to grant each other limited access to their information systems. Authentication and authorization are key to secure information handling. However, access control policies often rely on non-standardized attributes to describe the roles and permissions of their employees which convolutes cross-organizational authorization when business relationships evolve quickly. Our framework addresses the managerial overhead of continuous updates to access control policies for enterprise information systems to accommodate disparate attribute usage. By inferring attribute relationships, our framework facilitates attribute and policy reconciliation, and automatically aligns dynamic entitlements during the evaluation of authorization decisions. We validate our framework with a Industry 4.0 motivating scenario on networked production where such dynamic cross-enterprise collaborations are quintessential. The evaluation reveals the capabilities and performance of our framework, and illustrates the feasibility of liberating the security administrator from manually provisioning and aligning attributes, and verifying the consistency of access control policies for cross-enterprise collaborations.

    Background: HIV/AIDS control are one of the most important goals of the health systems. The aim of this study was to determine how HIV/AIDS control was initiated among policy makers’ agenda setting in Iran. Methods: A qualitative research (semi-structured interview) was conducted using Kingdon’s framework (problem, policy and politics streams, and policy windows and policy entrepreneurs) to analysis HIV/AIDS agenda setting in Iran. Thirty-two policy makers, managers, specialists, and researchers were interviewed. Also, 30 policy documents were analyzed. Framework analysis method was used for data analysis. Results: the increase of HIV among Injecting drug users (IDUs) and Female Sex Workers (FSWs), lack of control of their high-risk behaviors, and exceeding the HIV into concentrated phase were examples of problem stream. Policy stream was evidence-based solutions that highlighted the need for changing strategies for dealing with such a problem and finding technically feasible and acceptable solutions. Iran’s participation in United Nations General Assembly special sessions on HIV/AIDS (UNGASS), the establishment of National AIDS Committee; highlighting AIDS control in Iran’s five years development program and the support of the judiciary system of harm reduction policies were examples of politics stream. Policy entrepreneurs linking these streams put the HIV/AIDS on the national agenda (policy windows) and provide their solutions. Conclusion: There were mutual interactions among these three streams and sometimes, they weakened or reinforced each other. Future studies are recommended to understand the interactions between these streams’ parts and perhaps develop further Kingdon’s framework, especially in the health sector. PMID:27579283

    2005-05-01

    The US Food and Drug Administration's (FDA's) 1992 policy statement was developed in the context of critical gaps in scientific knowledge concerning the compositional effects of genetic transformation and severe limitations in methods for safety testing. FDA acknowledged that pleiotropy and insertional mutagenesis may cause unintended changes, but it was unknown whether this happens to a greater extent in genetic engineering compared with traditional breeding. Moreover, the agency was not able to identify methods by which producers could screen for unintended allergens and toxicants. Despite these uncertainties, FDA granted genetically engineered foods the presumption of GRAS (Generally Recognized As Safe) and recommended that producers use voluntary consultations before marketing them.

    With China's significant role on pollution emissions and related health damage, deep and up-to-date understanding of China's air pollution policies is of worldwide relevance. Based on scientific evidence for the evolution of air pollution and the institutional background of environmental governance in China, we examine the development of air pollution control policies from the 1980s and onwards. We show that: (1) The early policies, until 2005, were ineffective at reducing emissions; (2) During 2006-2012, new instruments which interact with political incentives were introduced in the 11th Five-Year Plan, and the national goal of reducing total sulfur dioxide (SO₂) emissions by 10% was achieved. However, regional compound air pollution problems dominated by fine particulate matter (PM 2.5 ) and ground level ozone (O₃) emerged and worsened; (3) After the winter-long PM 2.5 episode in eastern China in 2013, air pollution control policies have been experiencing significant changes on multiple fronts. In this work we analyze the different policy changes, the drivers of changes and key factors influencing the effectiveness of policies in these three stages. Lessons derived from the policy evolution have implications for future studies, as well as further reforming the management scheme towards air quality and health risk oriented directions.

    This article provides an overview on prescription drug abuse and highlights a number of related legislative bills introduced during the 112th Congress in response to this growing epidemic. Prescription drug abuse has emerged as the nation's fastest growing drug problem. Although prescription drugs have been used effectively and appropriately for decades, deaths from prescription pain medicine in particular have reached epidemic proportions. Bills related to prescription drug abuse introduced during the 112th Congress focus on strengthening provider and consumer education, tracking and monitoring prescription drug abuse, improving data collection on drug overdose fatalities, combating fraud and abuse in Medicare and Medicaid programs, reclassifying drugs to make them more difficult to prescribe and obtain, and enforcing stricter penalties for individuals who operate scam pain clinics and sell pain pills illegitimately. This article underscores the importance of a multifaceted approach to combating prescription drug abuse and concludes with implications for nursing. Copyright © 2013. Published by Mosby, Inc.

    The International community has been facing with the continued challenges for possession and proliferation of WMD over the past years. In addition, it is known that the terrorist groups are interested in acquiring WMD. The black market of WMD related materials and technologies show also the one of seriousness of our challenges. A number of international treaties, agreements and initiatives to control the proliferation of weapons of N, B, C and their delivery system have been existed to deal with these challenges, but their missions are challenged greatly in recent a series of nuclear issues by Iran and North Korea. The paper reviews the current international export control status and Korea export control system and policy. It also addresses some agenda to be done as future export control policy in Korea

  12. Explaining trends in addictive behaviour policy--the role of policy coherence.

    2014-05-01

    This article analyses addictive behaviour policy regimes - focusing on illegal drugs and gambling - in 19 countries over a period of 50 years. It compares how these countries have combined rules on the consumption and possession of cannabis and on the participation in sports betting with sanctions for violations of these rules. While theories of policy convergence can explain dominant trends in the way the combination of these policy instruments have changed, they cannot account for all of the empirical variation observed. Turning to Portugal, a case which deviates in both illegal drug and gambling policy from the expected trend, we show that explanations of policy change improve substantially when taking the concept of policy coherence into account. Specifically, we argue that changes of the policy status quo are facilitated when policy entrepreneurs succeed in shaping a perception of policy incoherence. In turn, when relevant actors are able to maintain a perception of policy coherence, the policy status quo is stabilized. Copyright © 2014 Elsevier B.V. All rights reserved.

    In this work, we inspect the reliability of controlling and quelling an epidemic disease mimicked by a susceptible–infected–susceptible (SIS) model defined on a complex network by means of current and implementable quarantine and isolation policies. Specifically, we consider that each individual in the network is originally linked to individuals of two types: members of the same household and acquaintances. The topology of this network evolves, taking into account a probability q that aims at representing the quarantine or isolation process in which the connection with acquaintances is severed according to standard policies of control of epidemics. Within current policies of self-isolation and standard infection rates, our results show that the propagation is either only controllable for hypothetical rates of compliance or not controllable at all

    Full Text Available Abstract Background More than 1 million tuberculosis (TB patients are receiving the standard anti-TB treatment provided by China National Tuberculosis Prevention and Control Scheme (CNTS in China every year. Adverse reactions (ADRs induced by anti-TB drugs could both do harm to patients and lead to anti-TB treatment failure. The ADACS aimed to explore ADRs' incidences, prognoses, economical and public health impacts for TB patients and TB control, and build a DNA bank of TB patients. Methods/Design Multiple study designs were adopted. Firstly, a prospective cohort with 4488 sputum smears positive pulmonary tuberculosis patients was established. Patients were followed up for 6-9 months in 52 counties of four regions. Those suspected ADRs should be checked and confirmed by Chinese State Food and Drug Administration (SFDA. Secondly, if the suspected ADR was anti-TB drug induced liver injury (ATLI, a nested case-control study would be performed which comprised choosing a matched control and doing a plus questionnaire inquiry. Thirdly, health economical data of ADRs would be collected to analyze financial burdens brought by ADRs and cost-effectiveness of ADRs' treatments. Fourthly, a drop of intravenous blood for each patient was taken and saved in FTA card for DNA banking and genotyping. Finally, the demographic, clinical, environmental, administrative and genetic data would be merged for the comprehensive analysis. Discussion ADACS will give an overview of anti-TB drugs induced ADRs' incidences, risk factors, treatments, prognoses, and clinical, economical and public health impacts for TB patients applying CNTS regimen in China, and provide suggestions for individualized health care and TB control policy.

    2016-06-01

    This article explores a key question in political sociology: Can post-communist policy-making be described with classical theories of the Western state or do we need a theory of the specificity of the post-communist state? In so doing, we consider Janine Wedel's clique theory, concerned with informal social actors and processes in post-communist transition. We conducted a case study of drug reimbursement policy in Poland, using 109 stakeholder interviews, official documents and media coverage. Drawing on 'sensitizing concepts' from Wedel's theory, especially the notion of 'deniability', we developed an explanation of why Poland's reimbursement policy combined suboptimal outcomes, procedural irregularities with limited accountability of key stakeholders. We argue that deniability was created through four main mechanisms: (1) blurred boundaries between different types of state authority allowing for the dispersion of blame for controversial policy decisions; (2) bridging different sectors by 'institutional nomads', who often escaped existing conflicts of interest regulations; (3) institutional nomads' 'flexible' methods of influence premised on managing roles and representations; and (4) coordination of resources and influence by elite cliques monopolizing exclusive policy expertise. Overall, the greatest power over drug reimbursement was often associated with lowest accountability. We suggest, therefore, that the clique theory can be generalized from its home domain of explanation in foreign aid and privatizations to more technologically advanced policies in Poland and other post-communist countries. This conclusion is not identical, however, with arguing the uniqueness of the post-communist state. Rather, we show potential for using Wedel's account to analyse policy-making in Western democracies and indicate scope for its possible integration with the classical theories of the state. © London School of Economics and Political Science 2016.

    2015-01-01

    This paper estimates an off-policy integral reinforcement learning (IRL) algorithm to obtain the optimal tracking control of unknown chaotic systems. Off-policy IRL can learn the solution of the HJB equation from the system data generated by an arbitrary control. Moreover, off-policy IRL can be regarded as a direct learning method, which avoids the identification of system dynamics. In this paper, the performance index function is first given based on the system tracking error and control error. For solving the Hamilton–Jacobi–Bellman (HJB) equation, an off-policy IRL algorithm is proposed. It is proven that the iterative control makes the tracking error system asymptotically stable, and the iterative performance index function is convergent. Simulation study demonstrates the effectiveness of the developed tracking control method. (paper)

    Background: In Nigeria, malaria, schistosomiasis and lymphatic filariasis are among infectious diseases of poverty (IDP) with severe health burden and require effective policy strategies for their control. In this study, we investigated the value of policy brief and policy dialogue as excellent policymaking mechanisms that enable policymakers to adapt effective evidence informed policy for IDP control. Methods: A policy brief was developed on the control of malaria, schistosomiasis and lymphatic filariasis and subjected to deliberations in a one-day multi-stakeholder policy dialogue held in Ebonyi State Nigeria. A modified cross sectional intervention study design was used in this investigation. Structured pre-tested questionnaires were used to evaluate the policy brief document and policy dialogue process at the end of the policy dialogue. Results: Forty-seven policymakers participated in the dialogue. An analysis of the response on the policy brief regarding context, different features of the problem; policy options and key implementation considerations indicated the mean ratings (MNRs) mostly ranged from 6.40-6.85 on 7 point scale. The over-all assessment of the policy brief had MNR at 6.54. The analysis of the response on the policy dialogue regarding the level of priority of policy issue, opportunity to discuss different features of the problem and options for addressing the problem, and the MNRs mostly ranged from 6.50-6.82. The overall assessment of the policy dialogue had MNR at 6.72. Conclusion: Policy dialogues can allow research evidence to be considered together with views, experiences and tacit knowledge of policymakers and can enhance evidence-to-policy link. PMID:26290826

  19. Influence of export control policy on the competitiveness of machine tool producing organizations

    Science.gov (United States)

    Ahrstrom, Jeffrey D.

    The possible influence of export control policies on producers of export controlled machine tools is examined in this quantitative study. International market competitiveness theories hold that market controlling policies such as export control regulations may influence an organization's ability to compete (Burris, 2010). Differences in domestic application of export control policy on machine tool exports may impose throttling effects on the competitiveness of participating firms (Freedenberg, 2010). Commodity shipments from Japan, Germany, and the United States to the Russian market will be examined using descriptive statistics; gravity modeling of these specific markets provides a foundation for comparison to actual shipment data; and industry participant responses to a user developed survey will provide additional data for analysis using a Kruskal-Wallis one-way analysis of variance. There is scarce academic research data on the topic of export control effects within the machine tool industry. Research results may be of interest to industry leadership in market participation decisions, advocacy arguments, and strategic planning. Industry advocates and export policy decision makers could find data of interest in supporting positions for or against modifications of export control policies.

    This is a methodological study investigating the online responses to a national debate over an important health and social problem in Russia. Russia is the largest Internet market in Europe, exceeding Germany in the absolute number of users. However, Russia is unusual in that the main search provider is not Google, but Yandex. This study had two main objectives. First, to validate Yandex search patterns against those provided by Google, and second, to test this method's adequacy for investigating online interest in a 2010 national debate over Russian illicit drug policy. We hoped to learn what search patterns and specific search terms could reveal about the relative importance and geographic distribution of interest in this debate. A national drug debate, centering on the anti-drug campaigner Egor Bychkov, was one of the main Russian domestic news events of 2010. Public interest in this episode was accompanied by increased Internet search. First, we measured the search patterns for 13 search terms related to the Bychkov episode and concurrent domestic events by extracting data from Google Insights for Search (GIFS) and Yandex WordStat (YaW). We conducted Spearman Rank Correlation of GIFS and YaW search data series. Second, we coded all 420 primary posts from Bychkov's personal blog between March 2010 and March 2012 to identify the main themes. Third, we compared GIFS and Yandex policies concerning the public release of search volume data. Finally, we established the relationship between salient drug issues and the Bychkov episode. We found a consistent pattern of strong to moderate positive correlations between Google and Yandex for the terms "Egor Bychkov" (r(s) = 0.88, P < .001), "Bychkov" (r(s) = .78, P < .001) and "Khimki"(r(s) = 0.92, P < .001). Peak search volumes for the Bychkov episode were comparable to other prominent domestic political events during 2010. Monthly search counts were 146,689 for "Bychkov" and 48,084 for "Egor Bychkov", compared to 53

  4. International trade agreements: a threat to tobacco control policy.

    International covenants establish a role for governments in ensuring the conditions for human health and wellbeing, which has been recognised as a central human right. International trade agreements, conversely, prioritize the rights of corporations over health and human rights. International trade agreements are threatening existing tobacco control policies and restrict the possibility of implementing new controls. This situation is unrecognised by many tobacco control advocates in signatory nations, especially those in developing countries. Recent agreements on eliminating various trade restrictions, including those on tobacco, have expanded far beyond simply international movement of goods to include internal tobacco distribution regulations and intellectual property rules regulating advertising and labelling. Our analysis shows that to the extent trade agreements protect the tobacco industry, in itself a deadly enterprise, they erode human rights principles and contribute to ill health. The tobacco industry has used trade policy to undermine effective barriers to tobacco importation. Trade negotiations provide an unwarranted opportunity for the tobacco industry to assert its interests without public scrutiny. Trade agreements provide the industry with additional tools to obstruct control policies in both developed and developing countries and at every level. The health community should become involved in reversing these trends, and help promote additional measures to protect public health.

    People who inject drugs (PWID) are underserved by health providers but pharmacies may be their most accessible care settings. Studies in the U.S., Russia, Vietnam, China, Canada and Mexico employed a three-level (macro-, meso-, and micro-) model to assess feasibility of expanded pharmacy services for PWID. Studies employed qualitative and quantitative interviews, review of legal and policy documents, and information on the knowledge, attitudes, and practices of key stakeholders. Studies produced a mixed assessment of feasibility. Provision of information and referrals by pharmacies is permissible in all study sites and sale and safe disposal of needles/syringes by pharmacies is legal in almost all sites, although needle/syringe sales face challenges related to attitudes and practices of pharmacists, police, and other actors. Pharmacy provision of HIV testing, hepatitis vaccination, opioid substitution treatment, provision of naloxone for drug overdose, and abscess treatment, face more serious legal and policy barriers. Challenges to expanded services for drug users in pharmacies exist at all three levels, especially the macro-level characterized by legal barriers and persistent stigmatization of PWID. Where deficiencies in laws, policies, and community attitudes block implementation, stakeholders should advocate for needed legal and policy changes and work to address community stigma and resistance. Laws and policies are only as good as their implementation, so attention is also needed to meso- and micro- levels. Policies, attitudes, and practices of police departments and pharmacy chains as well as knowledge, attitudes, and practices of individual PWID, individual pharmacies, and police officers should support rather than undermine positive laws and expanded services. Despite the challenges, pharmacies remain potentially important venues for delivering health services to PWID.

    2016-10-01

    Payers in the United States issue coverage determinations to guide how their enrolled beneficiaries use prescription drugs. Because payers create their own coverage policies, how they cover drugs can vary, which in turn can affect access to care by beneficiaries. To examine how the largest private payers based on membership cover drugs indicated for rheumatoid arthritis and to determine what evidence the payers reported reviewing when formulating their coverage policies. Coverage policies issued by the 10 largest private payers that make their policies publicly available were identified for rheumatoid arthritis drugs. Each coverage determination was compared with the drug's corresponding FDA label and categorized according to the following: (a) consistent with the label, (b) more restrictive than the label, (c) less restrictive than the label, or (d) mixed (i.e., more restrictive than the label in one way but less restrictive in another). Each coverage determination was also compared with the American College of Rheumatology (ACR) 2012 treatment recommendations and categorized using the same relative restrictiveness criteria. The policies were then reviewed to identify the evidence that the payers reported reviewing. The identified evidence was divided into the following 6 categories: randomized controlled trials; other clinical studies (e.g., observational studies); health technology assessments; clinical reviews; cost-effectiveness analyses; and clinical guidelines. Sixty-nine percent of coverage determinations were more restrictive than the corresponding FDA label; 15% were consistent; 3% were less restrictive; and 13% were mixed. Thirty-four percent of coverage determinations were consistent with the ACR recommendations, 33% were more restrictive; 17% were less restrictive; and 17% were mixed. Payers most often reported reviewing randomized controlled trials for their coverage policies (an average of 2.3 per policy). The payers reported reviewing an average of

    A range of biodegradable drug-nanofibres composite mats have been reported as drug delivery systems. However, their main disadvantage is the rapid release of the drug immediately after application. This paper reports an improved system based on the incorporation of drug conjugated-chitosan into polyvinyl alcohol (PVA) nanofibers. The results showed that controlled release of levofloxacin (LVF) could be achieved by covalently binding LVF to low molecular weight chitosan (CS) via a cleavable amide bond and then blending the conjugated CS with polyvinyl alcohol (PVA) nanofibres prior to electrospinning. PVA/LVF and PVA-CS/LVF nanofibres were fabricated as controls. The conjugated CS-LVF was characterized by FTIR, DSC, TGA and 1 H NMR. Scanning electron microscopy (SEM) showed that the blended CS-PVA nanofibres had a reduced fibre diameter compared to the controls. Drug release profiles showed that burst release was decreased from 90% in the control PVA/LVF electrospun mats to 27% in the PVA/conjugated CS-LVF mats after 8 h in phosphate buffer at 37 °C. This slower release is due to the cleavable bond between LVF and CS that slowly hydrolysed over time at neutral pH. The results indicate that conjugation of the drug to the polymer backbone is an effective way of minimizing burst release behaviour and achieving sustained release of the drug, LVF. - Highlights: • A novel drug delivery system for controlled release of drug was designed. • Composite PVA/conjugated CS-LVF nanofibres was fabricated by electrospinning. • Conjugated chitosan and composite nanofibres were characterized by various techniques. • Release profiles of drug were significantly improved in composite nanofibres containing drug conjugated chitosan.

    Design and synthesis of efficient drug delivery systems are of critical importance in health care management. Innovations in materials chemistry especially in polymer field allows introduction of advanced drug delivery systems since polymers could provide controlled release of drugs in predetermined doses over long periods, cyclic and tunable dosages. To this end, researchers have taken advantages of smart polymers since they can undergo large reversible, chemical, or physical fluctuations as responses to small changes in environmental conditions, for instance, in pH, temperature, light, and phase transition. The present review aims to highlight various kinds of smart polymers, which are used in controlled drug delivery systems as well as mechanisms of action and their applications.

    Tobacco use, particularly smoking, remains the number one cause of preventable disease and mortality in Japan. This review of the tobacco control policy and public health is the first to offer a composite review of the subject within Japan. This review attempts to evaluate the most important aspects of the current political economy of the tobacco control policy, and concludes that more effective control policies must be employed to minimize the impact of smoking on the public's health in Japan. Further the article attempts to place the approaches in the larger context of tobacco control, providing a vision for the future of tobacco prevention and control based on current knowledge. Tobacco use will remain the leading cause of preventable illness and death in Japan, until tobacco prevention and control efforts are commensurate with the harm caused by tobacco. Taken together, the results of various studies have clearly shown that control measures can influence tobacco smoking patterns, and in turn, the rate of tobacco-related problems. Government tobacco taxes have not kept pace with inflation for years. Availability of tobacco is virtually unlimited with easy access and the prices being very low due to the strong currency of Japan. Thus Japan must be one of the most tobacco accessible countries. It is important to ensure that people are not conditioned to smoke tobacco by an unduly favourable economic and commercial environment. For that reason, prevention advocates have called for substantial regulation of tobacco products and appeal for both tobacco tax increases and tobacco taxes to be indexed to inflation. In this review, present tobacco related public health policies in Japan are discussed with implication for prevention of tobacco related problems. Continued research in this area will be necessary to determine the most effective policies of reducing tobacco related problems in Japan.

    Full Text Available The international drug control regime is formulated under a basic paradigm: all drugs included in the convention schedules I, II and IV can only have medical and research uses. The policies derived from these conventions forbid all recreational, ritual, experimental, or self-medicating consumption of coca, cocaine, opium, heroin, marijuana and many other drugs. The conventions allow the production of controlled drugs for medical and research uses and criminalize all other production. Where consumption is concerned they are less rigid, as users of illegal drugs do not have to be arrested or jailed. Anti-drug policies seek to suppress both illicit drug supply and demand but are formulated without clearly spelling out the reasons why there is a demand and a supply for illegal drugs. To understand illegal drug demand and supply it is necessary to have clear answers to fundamental criminological questions such as: Why do people commit crimes? Or why some individuals contravene formal or informal norms while others do not? Policymakers, however, do not hesitate to formulate and implement anti-drug policies without having first considered those questions. They proceed as if their answers were obvious or known. Yet, when asked about the reasons why the illegal drugs industry develops in a location, most answers are highly questionable and at best partially right. The aim of this essay is to show this using Colombia as an example.

    We develop a method, employing Compton peak standardization and the use of matrix-matched spiked samples with Total Reflection X-ray Fluorescence (TXRF), for the determination of platinum plasma concentrations of patients undergoing chemotherapy with Pt-bearing drugs. Direct blood plasma analysis attains Pt detection limits of 70 ng/ml. Measurement results of prescribed drug doses are compared to achieved blood Pt concentrations indicating a lack of expected correlations. Direct analysis of Pt-containing infused drugs from a variety of suppliers indicates cases of abnormal concentrations which raises quality control issues. We demonstrate the potential usefulness of the method for pharmacokinetic studies or for routine optimization and quality control of Pt chemotherapy treatments

    (c.f. GM03,Mos05,Ris13) and manual analysis of the overall effect and consequences of a large XACML policy set is a very daunting and time-consuming task. In this thesis we address the problem of understanding the semantics of access control policy language XACML, in particular XACML version 3.0....... The main focus of this thesis is modelling and analysing access control policies in XACML 3.0. There are two main contributions in this thesis. First, we study and formalise XACML 3.0, in particular the Policy Decision Point (PDP). The concrete syntax of XACML is based on the XML format, while its standard...... semantics is described normatively using natural language. The use of English text in standardisation leads to the risk of misinterpretation and ambiguity. In order to avoid this drawback, we define an abstract syntax of XACML 3.0 and a formal XACML semantics. Second, we propose a logic-based XACML analysis...

    The model-free optimal control problem of general discrete-time nonlinear systems is considered in this paper, and a data-based policy gradient adaptive dynamic programming (PGADP) algorithm is developed to design an adaptive optimal controller method. By using offline and online data rather than the mathematical system model, the PGADP algorithm improves control policy with a gradient descent scheme. The convergence of the PGADP algorithm is proved by demonstrating that the constructed Q -function sequence converges to the optimal Q -function. Based on the PGADP algorithm, the adaptive control method is developed with an actor-critic structure and the method of weighted residuals. Its convergence properties are analyzed, where the approximate Q -function converges to its optimum. Computer simulation results demonstrate the effectiveness of the PGADP-based adaptive control method.

    Simulation models can be used to evaluate existing and potential tobacco control interventions, including policies. The purpose of this systematic review was to synthesize evidence from computational models used to project population-level effects of tobacco control interventions. We provide recommendations to strengthen simulation models that evaluate tobacco control interventions. Studies were eligible for review if they employed a computational model to predict the expected effects of a non-clinical US-based tobacco control intervention. We searched five electronic databases on July 1, 2013 with no date restrictions and synthesized studies qualitatively. Six primary non-clinical intervention types were examined across the 40 studies: taxation, youth prevention, smoke-free policies, mass media campaigns, marketing/advertising restrictions, and product regulation. Simulation models demonstrated the independent and combined effects of these interventions on decreasing projected future smoking prevalence. Taxation effects were the most robust, as studies examining other interventions exhibited substantial heterogeneity with regard to the outcomes and specific policies examined across models. Models should project the impact of interventions on overall tobacco use, including nicotine delivery product use, to estimate preventable health and cost-saving outcomes. Model validation, transparency, more sophisticated models, and modeling policy interactions are also needed to inform policymakers to make decisions that will minimize harm and maximize health. In this systematic review, evidence from multiple studies demonstrated the independent effect of taxation on decreasing future smoking prevalence, and models for other tobacco control interventions showed that these strategies are expected to decrease smoking, benefit population health, and are reasonable to implement from a cost perspective. Our recommendations aim to help policymakers and researchers minimize harm and

    Full Text Available In 2013, illegal drug use was responsible for 1.8% of years of life lost in the European Union, alcohol was responsible for 8.2% and tobacco for 18.2%, imposing economic burdens in excess of 2.5% of GDP. No single European country has optimal governance structures for reducing the harm done by nicotine, illegal drugs and alcohol, and existing ones are poorly designed, fragmented, and sometimes cause harm. Reporting the main science and policy conclusions of a transdisciplinary five-year analysis of the place of addictions in Europe, researchers from 67 scientific institutions addressed these problems by reframing an understanding of addictions.  A new paradigm needs to account for evolutionary evidence which suggests that humans are biologically predisposed to seek out drugs, and that, today, individuals face availability of high drug doses, consequently increasing the risk of harm.  New definitions need to acknowledge that the defining element of addictive drugs is ‘heavy use over time’, a concept that could replace the diagnostic artefact captured by the clinical term ‘substance use disorder’, thus opening the door for new substances to be considered such as sugar. Tools of quantitative risk assessment that recognize drugs as toxins could be further deployed to assess regulatory approaches to reducing harm. Re-designed governance of drugs requires embedding policy within a comprehensive societal well-being frame that encompasses a range of domains of well-being, including quality of life, material living conditions and sustainability over time; such a frame adds arguments to the inappropriateness of policies that criminalize individuals for using drugs and that continue to categorize certain drugs as illegal. A health footprint, modelled on the carbon footprint, and using quantitative measures such as years of life lost due to death or disability, could serve as the accountability tool that apportions responsibility for who and what

  18. Optimal Control of Drug Therapy in a Hepatitis B Model

    2016-08-01

    Full Text Available Combination antiviral drug therapy improves the survival rates of patients chronically infected with hepatitis B virus by controlling viral replication and enhancing immune responses. Some of these drugs have side effects that make them unsuitable for long-term administration. To address the trade-off between the positive and negative effects of the combination therapy, we investigated an optimal control problem for a delay differential equation model of immune responses to hepatitis virus B infection. Our optimal control problem investigates the interplay between virological and immunomodulatory effects of therapy, the control of viremia and the administration of the minimal dosage over a short period of time. Our numerical results show that the high drug levels that induce immune modulation rather than suppression of virological factors are essential for the clearance of hepatitis B virus.

    Rural, tobacco-growing areas are disproportionately affected by tobacco use, secondhand smoke, and weak tobacco control policies. The purpose was to test the effects of a stage-specific, tailored policy-focused intervention on readiness for smoke-free policy, and policy outcomes in rural underserved communities. A controlled community-based trial including 37 rural counties. Data were collected annually with community advocates (n = 330) and elected officials (n = 158) in 19 intervention counties and 18 comparison counties over 5 years (average response rate = 68%). Intervention communities received policy development strategies from community advisors tailored to their stage of readiness and designed to build capacity, build demand, and translate and disseminate science. Policy outcomes were tracked over 5 years. Communities receiving the stage-specific, tailored intervention had higher overall community readiness scores and better policy outcomes than the comparison counties, controlling for county-level smoking rate, population size, and education. Nearly one-third of the intervention counties adopted smoke-free laws covering restaurants, bars, and all workplaces compared to none of the comparison counties. The stage-specific, tailored policy-focused intervention acted as a value-added resource to local smoke-free campaigns by promoting readiness for policy, as well as actual policy change in rural communities. Although actual policy change and percent covered by the policies were modest, these areas need additional resources and efforts to build capacity, build demand, and translate and disseminate science in order to accelerate smoke-free policy change and reduce the enormous toll from tobacco in these high-risk communities. © 2014 National Rural Health Association.

    Study the association between the introduction of tobacco control policies in the Netherlands and changes in perinatal outcomes. National quasi-experimental study. We used Netherlands Perinatal Registry data (now called Perined) for the period 2000-2011. We studied whether the introduction of smoke-free legislation in workplaces plus a tobacco tax increase and mass media campaign in January 2004, and extension of the smoke-free law to the hospitality industry accompanied by another tax increase and media campaign in July 2008, was associated with changes in perinatal outcomes. We studied all singleton births (gestational age: 24+0 to 42+6 weeks). Our primary outcome measures were: perinatal mortality, preterm birth and being small-for-gestational-age (SGA). Interrupted time series logistic regression analyses were performed to investigate changes in these outcomes occurred after the introduction of the aforementioned tobacco control policies (ClinicalTrials.gov: NCT02189265). Among 2,069,695 singleton births, 13,027 (0.6%) perinatal deaths, 116,043 (5.6%) preterm live-births and 187,966 (9.1%) SGA live-births were observed. The policies introduced in January 2004 were not associated with significant changes in any of the primary outcome measures. A -4.4% (95% CI: -6.4 to -2.4; p hospitality industry, a further tax increase and another media campaign. This translates to an estimated over 500 cases of SGA being averted per year. A reduction in SGA births, but not preterm birth or perinatal mortality, was observed in the Netherlands after extension of the smoke-free workplace law to include bars and restaurants, in conjunction with a tax increase and media campaign in 2008.

  5. Pharmaceutical policies in European countries.

    2010-01-01

    Pharmaceutical expenditures have an important role in Europe. The attempts to control expenditure have used a wide range of policy measures. We reviewed the main measures adopted by the European Union countries, especially in countries where governments are the largest third-party payers. To complement a literature review on the topic, data was gathered from national reviews of health systems and direct inquiries to several government bodies. Almost all countries regulate prices of pharmaceutical products. Popular policy measures include international referencing to set prices (using as benchmark countries that have set lower prices), internal reference pricing systems to promote price competition in domestic markets, and positive lists for reimbursement to promote consumption of generics (including in some cases substitution by pharmacists of drugs prescribed by physicians). Despite the wide range of policy measures, it is not possible to identify a "silver bullet" to control pharmaceutical expenditures. We also identified two main policy challenges: policy coordination among countries within the European Union to maintain incentives for R&D at the global level, and the development of new relationships with the pharmaceutical industry; namely, the so-called risk-sharing agreements between the pharmaceutical industry and governments/regulators (or large third-party payers).

    This paper uses rational choice theory to analyse a new - and controversial - treatment approach to drug problems: services aimed at making clients capable of controlled use of illegal drugs. The paper highlights three mechanisms used in control-focused treatment: attempts to move drug use from the sphere of "wanting" to the sphere of "willing"; temporal framing of illegal drug use; and a therapeutic focus on clients' resources rather than their problems. Furthermore, the paper identifies some of the main challenges associated with this kind of treatment. The paper is based on 30 qualitative interviews with young people (aged 18-25) enrolled in drug treatment in Copenhagen, Denmark. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Background This is a methodological study investigating the online responses to a national debate over an important health and social problem in Russia. Russia is the largest Internet market in Europe, exceeding Germany in the absolute number of users. However, Russia is unusual in that the main search provider is not Google, but Yandex. Objective This study had two main objectives. First, to validate Yandex search patterns against those provided by Google, and second, to test this method's adequacy for investigating online interest in a 2010 national debate over Russian illicit drug policy. We hoped to learn what search patterns and specific search terms could reveal about the relative importance and geographic distribution of interest in this debate. Methods A national drug debate, centering on the anti-drug campaigner Egor Bychkov, was one of the main Russian domestic news events of 2010. Public interest in this episode was accompanied by increased Internet search. First, we measured the search patterns for 13 search terms related to the Bychkov episode and concurrent domestic events by extracting data from Google Insights for Search (GIFS) and Yandex WordStat (YaW). We conducted Spearman Rank Correlation of GIFS and YaW search data series. Second, we coded all 420 primary posts from Bychkov's personal blog between March 2010 and March 2012 to identify the main themes. Third, we compared GIFS and Yandex policies concerning the public release of search volume data. Finally, we established the relationship between salient drug issues and the Bychkov episode. Results We found a consistent pattern of strong to moderate positive correlations between Google and Yandex for the terms "Egor Bychkov" (r s = 0.88, P < .001), “Bychkov” (r s = .78, P < .001) and “Khimki”(r s = 0.92, P < .001). Peak search volumes for the Bychkov episode were comparable to other prominent domestic political events during 2010. Monthly search counts were 146,689 for “Bychkov” and

    Löfgren, Hans

    2007-06-01

    This article provides a synopsis of the new dynamics of the global biopharma industry. The emergence of global generics companies with capabilities approximating those of 'big pharma' has accelerated the blurring of boundaries between the innovator and generics sectors. Biotechnology-based products form a large and growing segment of prescription drug markets and regulatory pathways for biogenerics are imminent. Indian biopharma multinationals with large-scale efficient manufacturing plants and growing R&D capabilities are now major suppliers of Active Pharmaceutical Ingredients (APIs) and generic drugs across both developed and developing countries. In response to generic competition, innovator companies employ a range of life cycle management techniques, including the launch of 'authorised generics'. The generics segment in Australia will see high growth rates in coming years but the prospect for local manufacturing is bleak. The availability of cheap generics in international markets has put pressure on Pharmaceutical Benefits Scheme (PBS) pricing arrangements, and a new policy direction was announced in November 2006. Lower generics prices will have a negative impact on some incumbent suppliers but industrial renewal policies for the medicines industry in Australia are better focused on higher value R&D activities and niche manufacturing of sophisticated products.

    Nuclear Safety and Security Commission(NSSC) has amended two public notices about the regulation of nuclear material accounting and control(NMAC). Those notices were declared in November 2014 and entry into force since 2015. According to this legislation, a new type of NMAC inspection system was introduced and facility rules for NMAC approved by the government should be revised subsequently. These changes were one of the preemptive actions to cope with the emergence of new international safeguards policy and increasing demand on advanced nuclear technology. Generally, the regulation policy affects the nuclear business including research and development. Therefore, understanding of the new policy and its making process may help stakeholders to minimize unnecessary financial and operational burden. This study describes background, features, and institutionalization of the new regulation policy for NMAC. The new regulation policy for NMAC was established and institutionalized to preemptively cope with the internal and external demand on 'better' national system of accounting and control of nuclear material. This new policy and regulation system may call not only the regulator but also nuclear business operators for new works to make their system more effective and efficient.

    2012-01-01

    Our objective is to review and assess the main pharmaceutical cost-containment policies used in Ireland in recent years, and to highlight how a policy that improved fiscal sustainability but worsened economic sustainability could have improved both if an option-based approach was implemented. The main public pharmaceutical cost-containment policy measures including reducing the ex-factory price of drugs, pharmacy dispensing fees and community drug scheme coverage, and increasing patient copayments are outlined along with the resulting savings. We quantify the cost implications of a new policy that restricts the entitlement to free prescription drugs of persons older than 70 years and propose an alternative option-based policy that reduces the total cost to both the state and the patient. This set of policy measures reduced public spending on community drugs by an estimated €380m in 2011. The policy restricting free prescription drugs for persons older than 70 years, though effective in reducing public cost, increased the total cost of the drugs supplied. The policy-induced cost increase stems from a fees anomaly between the two main community drugs schemes which is circumvented by our alternative option-based policy. Our findings highlight the need for policymakers, even when absorbed with reducing cost, to design cost-containment policies that are both fiscally and economically sustainable.

    Injectable anesthetic drugs used in rodents are often mixed and further diluted to increase the convenience and accuracy of dosing. We evaluated clinical refractometry as a simple and rapid method of quality control and mixing error detection of rodent anesthetic or analgesic mixtures. Dilutions of ketamine, xylazine, acepromazine, and buprenorphine were prepared with reagent-grade water to produce at least 4 concentration levels. The refraction of each concentration then was measured with a clinical refractometer and plotted against the percentage of stock concentration. The resulting graphs were linear and could be used to determine the concentration of single-drug dilutions or to predict the refraction of drug mixtures. We conclude that refractometry can be used to assess the concentration of dilutions of single drugs and can verify the mixing accuracy of drug combinations when the components of the mixture are known and fall within the detection range of the instrument.

  15. Stimuli-Responsive Liposomes for Controlled Drug Delivery

    KAUST Repository

    Li, Wengang

    2014-09-01

    Liposomes are promising drug delivery vesicles due to their biodegradibility, large volume and biocompatibility towards both hydrophilic and hydrophobic drugs. They suffer, however, from poor stability which limits their use in controlled delivery applications. Herein, a novel method was devised for modification of liposomes with small molecules, polymers or nanoparticles to afford stimuli responsive systems that release on demand and stay relatively stable in the absence of the trigger.. This dissertation discusses thermosensitive, pH sensitive, light sensitive and magnetically triggered liposomes that have been prepared for controlled drug delivery application. RAFT polymerization was utilized for the preparation of thermosensitive liposomes (Cholesterol-PNIPAm) and acid-labile liposomes (DOPE-PAA). With low Mw Cholesterol-PNIPAm, the thermosensitive liposomes proved to be effective for controlled release and decreased the cytotoxicity of PNIPAm by eliciting the polymer doses. By crosslinking the DOPE-PAA on liposome surface with acid-labile diamine linkers, DOPE-PAA liposomes were verified to be sensitive at low pH. The effects of polymer structures (linear or hyperbranched) have also been studied for the stability and release properties of liposomes. Finally, a dual-responsive Au@SPIO embedded liposome hybrid (ALHs) was prepared with light-induced “on-and-off” function by photo-thermal process (visible light) and instant release properties triggered by alternating magnetic field, respectively. The ALH system would be further applied into the cellular imaging field as MRI contrast agent.

    Full Text Available Abstract Background National malaria control programmes must deal with the complex process of changing national malaria treatment guidelines, often without guidance on the process of change. Selecting a replacement drug is only one issue in this process. There is a paucity of literature describing successful malaria treatment policy changes to help guide control programs through this process.

Methods Using qualitative methods (individual and focus group interviews, stakeholder analysis and a review of documents, a retrospective analysis of the process of change in Peru's anti-malarial treatment policy from the early 1990's to 2003 was completed. Results The decision to change Peru's policies resulted from increasing levels of anti-malarial drug resistance, as well as complaints from providers that the drugs were no longer working. The context of the change occurred in a time in which Peru was changing national governments, which created extreme challenges in moving the change process forward. Peru utilized a number of key strategies successfully to ensure that policy change would occur. This included a having the process directed by a group who shared a common interest in malaria and who had long-established social and professional networks among themselves, b engaging in collaborative teamwork among nationals and between nationals and international collaborators, c respect for and inclusion of district-level staff in all phases of the process, d reliance on high levels of technical and scientific knowledge, e use of standardized protocols to collect data, and f transparency. Conclusion Although not perfectly or fully implemented by 2003, the change in malaria treatment policy in Peru occurred very quickly, as compared to other countries. They identified a problem, collected the data necessary to justify the

    2010-12-01

    Full Text Available This article analyzes the birth control policies in China during the Maoist era (1949- 1976. Considering Chinese and foreign sources, it is explained how the different campaigns of family planning took place and how these campaigns were subjected positively and negatively to the policies of the supreme leader Mao Zedong. Although only the last one had a real impact on the fight against overpopulation, all campaigns helped to promote the necessity of confronting this phenomenon. More importantly, they laid the foundations of the birth control policies that currently take place in China.

    In September 2007, the FDA issued an alert recommending that ceftriaxone and calcium-containing solutions should not be administered to any patient within 48 h of each other. Due to the widespread use of ceftriaxone, significant concern was expressed by the greater healthcare community about the warning, which the FDA eventually retracted in April of 2009. We sought to quantify the impact of the warning on healthcare institutions. A survey was administered to the membership of the Society of Infectious Diseases Pharmacists to quantify perceived changes in ceftriaxone use among healthcare institutions across the United States. A survey of Infectious Diseases experts was conducted. Participants were queried for hospital policies/drug use statistics during two times: immediately after the FDA warning and approximately 13 months post warning (preceding the FDA retraction). Related changes in formulary, drug-use policy, and the number of employee hours that were devoted to addressing the FDA warning were assessed. Ninety-four surveys representing 94 hospital systems were included in the analysis. Approximately half (n = 49, 52%) of respondent institutions enacted at least one drug-use policy change based on the warning; one institution removed ceftriaxone from a clinical protocol. Institutions' final interpretations of the warning differed slightly from initial understanding of the warning, and there was an overall minor decrease in the perceived use of ceftriaxone. The majority of those surveyed (n = 70, 74%) estimated that their respective institutions devoted between 1 and 49 employee hours to address the warning. Hospitals with ID pharmacists had minimal changes to ceftriaxone use after the 2007 FDA warning. Specialized pharmacists may be uniquely situated to help hospitals interpret global recommendations locally.

    In Kenya, cardiovascular diseases (CVDs) accounted for more than 10% of total deaths and 4% of total Disability-Adjusted Life Years (DALYs) in 2015 with a steady increase over the past decade. The main objective of this paper was to review the existing policies and their content in relation to prevention, control and management of CVDs at primary health care (PHC) level in Kenya. A targeted document search in Google engine using keywords "Kenya national policy on cardiovascular diseases" and "Kenya national policy on non-communicable diseases (NCDs)" was conducted in addition to key informant interviews with Kenyan policy makers. Relevant regional and international policy documents were also included. The contents of documents identified were reviewed to assess how well they aligned with global health policies on CVD prevention, control and management. Thematic content analysis of the key informant interviews was also conducted to supplement the document reviews. A total of 17 documents were reviewed and three key informants interviewed. Besides the Tobacco Control Act (2007), all policy documents for CVD prevention, control and management were developed after 2013. The national policies were preceded by global initiatives and guidelines and were similar in content with the global policies. The Kenya health policy (2014-2030), The Kenya Health Sector Strategic and Investment Plan (2014-2018) and the Kenya National Strategy for the Prevention and Control of Non-communicable diseases (2015-2020) had strategies on NCDs including CVDs. Other policy documents for behavioral risk factors (The Tobacco Control Act 2007, Alcoholic Drinks Control (Licensing) Regulations (2010)) were available. The National Nutrition Action Plan (2012-2017) was available as a draft. Although Kenya has a tiered health care system comprising primary healthcare, integration of CVD prevention and control at PHC level was not explicitly mentioned in the policy documents. This review revealed

  1. Identifying Demand Responses to Illegal Drug Supply Interdictions.

    2016-10-01

    Successful supply-side interdictions into illegal drug markets are predicated on the responsiveness of drug prices to enforcement and the price elasticity of demand for addictive drugs. We present causal estimates that targeted interventions aimed at methamphetamine input markets ('precursor control') can temporarily increase retail street prices, but methamphetamine consumption is weakly responsive to higher drug prices. After the supply interventions, purity-adjusted prices increased then quickly returned to pre-treatment levels within 6-12 months, demonstrating the short-term effects of precursor control. The price elasticity of methamphetamine demand is -0.13 to -0.21 for self-admitted drug treatment admissions and between -0.24 and -0.28 for hospital inpatient admissions. We find some evidence of a positive cross-price effect for cocaine, but we do not find robust evidence that increases in methamphetamine prices increased heroin, alcohol, or marijuana drug use. This study can inform policy discussions regarding other synthesized drugs, including illicit use of pharmaceuticals. Copyright © 2015 John Wiley & Sons, Ltd.

    2015-03-01

    Nanotechnology use in drug delivery promotes a reduction in systemic toxicity, improved pharmacokinetics, and better drug bioavailability. Liposomes continue to be extensively researched as drug delivery systems (DDS) with formulations such as Doxil® and Ambisome® approved by FDA and successfully marketed in the United States. However, the limited ability to precisely control release of active ingredients from these vesicles continues to challenge the broad implementation of this technology. Moreover, the full potential of the carrier to sequester drugs until it can reach its intended target has yet to be realized. Here, we describe a liposomal DDS that releases therapeutic doses of an anticancer drug in response to external stimulus. Earlier, we introduced degradable plasmon resonant liposomes. These constructs, obtained by reducing gold on the liposome surface, facilitate spatial and temporal release of drugs upon laser light illumination that ultimately induces an increase in temperature. In this work, plasmon resonant liposomes have been developed to stably encapsulate and retain doxorubicin at physiological conditions represented by isotonic saline at 37o C and pH 7.4. Subsequently, they are stimulated to release contents either by a 5o C increase in temperature or by laser illumination (760 nm and 88 mW/cm2 power density). Successful development of degradable plasmon resonant liposomes responsive to near-infrared light or moderate hyperthermia can provide a new delivery method for multiple lipophilic and hydrophilic drugs with pharmacokinetic profiles that limit clinical utility.

  3. Differentiating drugs by harm potential: the rational versus the feasible.

    Kalant, H

    1999-01-01

    In an ideal harm reduction model, drugs would be ranked according to their potential to cause harm, with varying implications for control policies and interventions. In such a public health oriented approach, the maximum protection of the public from harm would be balanced with the least possible restriction of freedom. In reality, however, the accuracy and completeness of the necessary information for such a ranking is highly limited. Many other factors not readily incorporated in a rational model, such as values, beliefs, and traditions, also affect drug policy decisions. Thus, rather than relying on acquisition of the necessary knowledge, it may be preferable to focus efforts on developing effective nonlegal measures to reduce drug use and harm.

    Drug addiction is present in a significant proportion of the population in the USA and worldwide. Drug addiction can occur with the abuse of many types of substances including cocaine, marijuana, stimulants, alcohol, opioids, and tranquilizers. There is a high likelihood that clinicians will encounter patients with substance abuse disorders on a regular basis with the prevalence of the use of illicit substances and the high rate of abuse of prescription drugs. The use of abuse deterrent formulations of prescription opioid agents, pill counts, and urine drug abuse screenings are all useful strategies. Optimum pain management of patients with addiction in the outpatient and inpatient setting is essential to minimize pain states. Careful selection of medications and appropriate oversight, including drug agreements, can reduce drug-induced impairments, including sleep deficits and diminished physical, social, and sexual functioning. This review, therefore, discusses the prevalence of illicit and prescription drug addiction, the challenges of achieving optimum pain control, and the therapeutic approaches to be considered in this challenging population. More research is warranted to develop improved therapies and routes of treatments for optimum pain relief and to prevent the development of central sensitization, chronic pain, and impaired physical and social functioning in patients with drug addiction.

    2015-01-01

    Transdermal drug delivery systems (TDDS) are used for the delivery of the drugs through the skin into the systemic circulation by applying them to the intact skin. The development of TDDS is a complex and multidisciplinary affair which involves identification of suitable drug, excipients and various other components. There have been numerous problems reported with respect to TDDS quality and performance. These problems can be reduced by appropriately addressing chemistry, manufacturing and controls requirements, which would thereby result in development of robust TDDS product and processes. This article provides recommendations on the chemistry, manufacturing and controls focusing on the unique technical aspects of TDDS.

  6. Effectiveness of hospital-wide methicillin-resistant Staphylococcus aureus (MRSA infection control policies differs by ward specialty.

    Directory of Open Access Journals (Sweden)

    Rosemarie Sadsad

    Full Text Available Methicillin-resistant Staphylococcus aureus (MRSA is a major cause of preventable nosocomial infections and is endemic in hospitals worldwide. The effectiveness of infection control policies varies significantly across hospital settings. The impact of the hospital context towards the rate of nosocomial MRSA infections and the success of infection control is understudied. We conducted a modelling study to evaluate several infection control policies in surgical, intensive care, and medical ward specialties, each with distinct ward conditions and policies, of a tertiary public hospital in Sydney, Australia. We reconfirm hand hygiene as the most successful policy and find it to be necessary for the success of other policies. Active screening for MRSA, patient isolation in single-bed rooms, and additional staffing were found to be less effective. Across these ward specialties, MRSA transmission risk varied by 13% and reductions in the prevalence and nosocomial incidence rate of MRSA due to infection control policies varied by up to 45%. Different levels of infection control were required to reduce and control nosocomial MRSA infections for each ward specialty. Infection control policies and policy targets should be specific for the ward and context of the hospital. The model we developed is generic and can be calibrated to represent different ward settings and pathogens transmitted between patients indirectly through health care workers. This can aid the timely and cost effective design of synergistic and context specific infection control policies.

    To identify the key formulation factors controlling the initial drug and polymer dissolution rates from an amorphous solid dispersion (ASD). Ketoconazole (KTZ) ASDs using PVP, PVP-VA, HMPC, or HPMC-AS as polymeric matrix were prepared. For each drug-polymer system, two types of formulations with the same composition were prepared: 1. Spray dried dispersion (SDD) that is homogenous at molecular level, 2. Physical blend of SDD (80% drug loading) and pure polymer (SDD-PB) that is homogenous only at powder level. Flory-Huggins interaction parameters (χ) between KTZ and the four polymers were obtained by Flory-Huggins model fitting. Solution (13)C NMR and FT-IR were conducted to investigate the specific drug-polymer interaction in the solution and solid state, respectively. Intrinsic dissolution of both the drug and the polymer from ASDs were studied using a Higuchi style intrinsic dissolution apparatus. PXRD and confocal Raman microscopy were used to confirm the absence of drug crystallinity on the tablet surface before and after dissolution study. In solid state, KTZ is completely miscible with PVP, PVP-VA, or HPMC-AS, demonstrated by the negative χ values of -0.36, -0.46, -1.68, respectively; while is poorly miscible with HPMC shown by a positive χ value of 0.23. According to solution (13)C NMR and FT-IR studies, KTZ interacts with HPMC-AS strongly through H-bonding and dipole induced interaction; with PVPs and PVP-VA moderately through dipole-induced interactions; and with HPMC weakly without detectable attractive interaction. Furthermore, the "apparent" strength of drug-polymer interaction, measured by the extent of peak shift on NMR or FT-IR spectra, increases with the increasing number of interacting drug-polymer pairs. For ASDs with the presence of considerable drug-polymer interactions, such as KTZ/PVPs, KTZ/PVP-VA, or KTZ /HPMC-AS systems, drug released at the same rate as the polymer when intimate drug-polymer mixing was ensured (i.e., the SDD systems

    Knopf, J.W.

    1991-01-01

    The author seeks to ascertain whether and how citizens' movements concerning nuclear arms control and disarmament affect US arms control policy. The author employs a comparative case study methodology. He examines cases of the Eisenhower and Kennedy Administrations during the period of protest against nuclear testing, and the Reagan Administration during the nuclear weapons freeze campaign and the subsequent campaign for a comprehensive test ban. He hows there are four mechanisms through which public advocacy efforts can influence arms control policy, identifies the conditions under which each can be effective, and details the type of impact each mechanism has. Domestic activism interacts with broader public opinion in a way that creates electoral pressure; with elite-level debates in a way that removes a consensus behind presidential policy or changes the winning coalition in Congress; with bureaucratic politics, by generating ideas that have utility for some agents within the Executive; or with the public diplomacy of foreign governments, especially the Soviet Union. Citizens' movements had an impact on policy in each of the cases studied. The type and extent of impact, and the mechanisms involved in giving activism influence, are different for each case

    This paper uses the framework of institutional economics to assess the impact of formal and informal institutions that influence the transaction costs on the cannabis market, and users' decisions to self-supply in the Czech Republic and the Netherlands, two countries with seemingly identical policies towards cannabis cultivation. A comparative analysis was conducted using secondary qualitative and quantitative data in four areas that were identified as relevant to the decision to cultivate cannabis: (i) the rules of the game - cannabis cultivation policy; (ii) "playing the game" - implementation of cannabis cultivation policy, (iii) informal institutions - cannabis cultivation culture, and (iv) the transaction costs of the cannabis market - availability, quality, and relative cannabis prices adjusted by purchasing power parity. Although the two policies are similar, their implementation differs substantially. In the Czech Republic, law enforcement has focused almost exclusively on large-scale cultivation. This has resulted in a competitive small-scale cultivation market, built upon a history of cannabis self-supply, which is pushing cannabis prices down. In the Netherlands, the costs of establishing one's own self-supply have historically outweighed the costs associated with buying in coffee shops. Additionally, law enforcement has recently pushed small-scale growers away from the market, and a large-scale cannabis supply, partly controlled by organised criminal groups, has been established that is driving prices up. The Czech cannabis prices have become relatively lower than the Dutch prices only recently, and the decision to buy on the market or to self-supply will be further shaped by the transactions costs on both markets, by policy implementation and by the local culture. The ability to learn from the impacts of cannabis cultivation policies conducted within the framework of UN drug treaties is particularly important at a time when increasing numbers of

    In 2009, Mexican Federal Government enacted "narcomenudeo" reforms decriminalizing possession of small amounts of drugs, delegating prosecution of retail drug sales to the state courts, and mandating treatment diversion for habitual drug users. There has been insufficient effort to formally assess the decriminalization policy's population-level impact, despite mounting interest in analagous reforms across the globe. Using a dataset of municipal police incident reports, we examined patterns of drug possession, and violent and non-violent crime arrests between January 2009 and December 2014. A hierarchical panel data analysis with random effects was conducted to assess the impact of narcomenudeo's drug decriminalization provision. The reforms had no significant impact on the number of drug possession or violent crime arrests, after controlling for other variables (e.g. time trends, electoral cycles, and precinct-level socioeconomic factors). Time periods directly preceding local elections were observed to be statistically associated with elevated arrest volume. Analysis of police statistics parallel prior findings that Mexico's reform decriminalizing small amounts of drugs does not appear to have significantly shifted drug law enforcement in Tijuana. More research is required to fully understand the policy transformation process for drug decriminalization and other structural interventions in Mexico and similar regional and international efforts. Observed relationship between policing and political cycles echo associations in other settings whereby law-and-order activities increase during mayoral electoral campaigns.

    2017-11-01

    The oral mucosa has recently become increasingly important as an alternative administration route for tailor-made, controlled drug delivery. Oromucosal multilayer films, assigned to the monograph oromucosal preparations in the Ph.Eur. may be a promising dosage form to overcome the requirements related to this drug delivery site. Areas covered: We provide an overview of multilayer films as drug delivery tools, and discuss manufacturing processes and characterization methods. We focus on the suitability of characterization methods for particular requirements of multilayer films. A classification was performed covering indication areas and APIs incorporated in multilayer film systems for oromucosal use in order to provide a summary of data published in this field. Expert opinion: The shift in drug development to high molecular weight drugs will influence the field of pharmaceutical development and delivery technologies. For a high number of indication areas, such as hormonal disorders, cardiovascular diseases or local treatment of infections, the flexible layer design of oromucosal multilayer films provides a promising option for tailor-made, controlled delivery of APIs to or through defined surfaces in the oral cavity. However, there is a lack of discriminating or standardized testing methods to assess the quality of multilayer films in a reliable way.

    Drug problems are reemerging in China since the nation implemented economic reform and an "open door" policy in the early 1980s. This is causing both national and international concern. However, knowledge and understanding of the Chinese drug problem is fairly limited because of the nation's unique social and political history. In response to this shortage of information, our study presents a profile of Chinese drug users. Data were collected from a survey of drug users attending mandatory treatment centres in a large city in 2009. We present a demographic profile of the drug users, describe their patterns of drug use, their access to drugs and their history of drug treatment. Chinese drug users, like those from the U.S., are likely to be unemployed and have a low level of education. However, they are more likely than those in the U.S. to use heroin, Bingdu (methamphetamine) and Maguo (a derivative of methamphetamine), and they pay less for their drugs. This profile of drug users is informative and valuable for drug prevention, intervention, and treatment in the Chinese setting because knowing and understanding the drug population is essential for effective control.

  16. Microfluidic synthesis of microfibers for magnetic-responsive controlled drug release and cell culture.

    Directory of Open Access Journals (Sweden)

    Yung-Sheng Lin

    Full Text Available This study demonstrated the fabrication of alginate microfibers using a modular microfluidic system for magnetic-responsive controlled drug release and cell culture. A novel two-dimensional fluid-focusing technique with multi-inlets and junctions was used to spatiotemporally control the continuous laminar flow of alginate solutions. The diameter of the manufactured microfibers, which ranged from 211 µm to 364 µm, could be well controlled by changing the flow rate of the continuous phase. While the model drug, diclofenac, was encapsulated into microfibers, the drug release profile exhibited the characteristic of a proper and steady release. Furthermore, the diclofenac release kinetics from the magnetic iron oxide-loaded microfibers could be controlled externally, allowing for a rapid drug release by applying a magnetic force. In addition, the successful culture of glioblastoma multiforme cells in the microfibers demonstrated a good structural integrity and environment to grow cells that could be applied in drug screening for targeting cancer cells. The proposed microfluidic system has the advantages of ease of fabrication, simplicity, and a fast and low-cost process that is capable of generating functional microfibers with the potential for biomedical applications, such as drug controlled release and cell culture.

    A wide variety of delivery systems have been developed and many products based on the drug delivery technology are commercially available. The development of controlled-release technologies accelerated new dosage form design by altering pharmacokinetic and pharmacodynamics profiles of given drugs, resulting in improved efficacy and safety. Various natural or synthetic polymers have been applied to make matrix, reservoir or implant forms due to the characteristics of polymers, especially ease of control for modifications of biocompatibility, biodegradation, porosity, charge, mechanical strength and hydrophobicity/hydrophilicity. Hydrogel is a hydrophilic, polymeric network capable of imbibing large amount of water and biological fluids. This review article introduces various applications of natural and synthetic polymer-based hydrogels from pharmaceutical, biomedical and bioengineering points of view.

    Full Text Available The European Respiratory Society is an international medical organisation that brings together physicians, healthcare professionals, scientists and other experts working in respiratory medicine. Its aim is to alleviate suffering from respiratory diseases and promote lung health globally through science, education and advocacy. ERS has since its founding in 1990 demonstrated strong commitment to tobacco control. Through scientific assemblies, education courses, various alliances and collaboration (Framework Convention Alliance, European Chronic Disease Alliance, World Health Organisation etc. As well as a Tobacco Control Committee (TCC dedicated to advocacy, ERS constantly strives to promote strong and evidence-based policies to reduce the burden of tobacco related diseases. One of the main outcome of the TCC is the creation of Smokehaz, a website aimed at providing policy-makers with scientific information on the Health hazards associated with smoking. Recently, ERS created the Latin-America Working Group which aims at strengthening tobacco control activities in Spain, Portugal and Latin-American countries.

    Institute of Scientific and Technical Information of China (English)

    Dong-Xi Liu

    2007-01-01

    The problem of regulating access to XML documents has attracted much attention from both academic and industry communities.In existing approaches, the XML elements specified by access policies are either accessible or inac-cessible according to their sensitivity.However, in some cases, the original XML elements are sensitive and inaccessible, but after being processed in some appropriate ways, the results become insensitive and thus accessible.This paper proposes a policy language to accommodate such cases, which can express the downgrading operations on sensitive data in XML documents through explicit calculations on them.The proposed policy language is called calculation-embedded schema (CSchema), which extends the ordinary schema languages with protection type for protecting sensitive data and specifying downgrading operations.CSchema language has a type system to guarantee the type correctness of the embedded calcula-tion expressions and moreover this type system also generates a security view after type checking a CSchema policy.Access policies specified by CSchema are enforced by a validation procedure, which produces the released documents containing only the accessible data by validating the protected documents against CSchema policies.These released documents are then ready tobe accessed by, for instance, XML query engines.By incorporating this validation procedure, other XML processing technologies can use CSchema as the access control module.

    A Compulsory Drug Treatment Correctional Center (CDTCC) was established in Australia in 2006 for repeat drug-related male offenders. Compulsory treatment law is inconsistent with a therapeutic jurisprudence approach. Despite the compulsory law, a normative offender rehabilitation framework has been established based on offender moral rights. Within moral rights, the offender rehabilitation framework addresses the core values of freedom (supporting autonomous decision-making) and well-being (supporting support physical, social, and psychological needs). Moral rights are underpinned by a theory or principle which, in this instance, is a humane approach to offender rehabilitation. While a law that permits offenders to choose drug treatment and rehabilitation is preferable, the article discusses the establishment of a prison based on therapeutic policy, principles, and practices that respond to participants as both rights-violators and rights-holders. The opportunity for accelerated community access and a therapeutic alliance with staff has resulted in offenders actively seeking to be ordered into compulsory drug treatment and rehabilitation.

    Progress in tobacco control policy making has occurred worldwide through advocacy campaigns involving multiple players- civil society groups, activists, academics, media and policymakers. The Framework Convention on Tobacco Control (FCTC)-the first ever global health treaty-outlines evidence-based tobacco control policies. Lebanon ratified the FCTC in 2005, but until 2011, tobacco control policies remained rudimentary and not evidence-based. Beginning in 2009, a concerted advocacy campaign was undertaken by a variety of stakeholders with the aim of accelerating the process of adopting a strong tobacco control policy. The campaign was successful, and Law 174 passed the Lebanese Parliament in August 2011. In this article, we analyse the policy making process that led to the adoption of Law 174 using Kingdon's model. The analysis relies on primary and secondary data sources including historical records of key governmental decisions, documentation of the activities of the concerted advocacy campaign and in-depth interviews with key stakeholders. We describe the opening of a window of opportunity as a result of the alignment of the problem, policy and politics streams. Furthermore, findings revealed that despite the challenge of persistent tobacco industry interference and established power relations between the industry, its allies and policymakers; policy entrepreneurs succeeded in supporting the alignment of the streams, and influencing the passage of the law. Kingdon's multiple stream approach was useful in explaining how tobacco control became an emerging policy issue at the front of the policy agenda in Lebanon.

    Full Text Available ABSTRACT Topically applied therapy is the most common way to treat ocular diseases, however given the anatomical and physiological constraints of the eye, frequent dosing is required with possible repercussions in terms of patient compliance. Beyond refractive error correction, contact lenses (CLs have, in the last few decades emerged as a potential ophthalmic drug controlled release system (DCRS. Extensive research is underway to understand how to best modify CLs to increase residence time and bioavailability of drugs within therapeutic levels on the ocular surface.These devices may simultaneously correct ametropia and have a role in managing ophthalmic disorders that can hinder CL wear such as dry eye, glaucoma, ocular allergy and cornea infection and injury. In this narrative review the authors explain how the ocular surface structures determine drug diffusion in the eye and summarize the strategies to enhance drug residence time and bioavailability. They synthesize findings and clinical applications of drug soaked CLs as DCRS combined with delivery diffusion barriers, incorporation of functional monomers, ion related controlled release, molecular imprinting, nanoparticles and layering. The authors draw conclusions about the impact of these novel ophthalmic agents delivery systems in improving drug transport in the target tissue and patient compliance, in reducing systemic absorption and undesired side effects, and discuss future perspectives.

    Full Text Available Unlike the typical stage-based policy commonly applied in Japan, the group-based control (often called movement-based in the traffic control industry in Japan refers to such a control pattern that the controller is capable of separately allocating time to each signal group instead of stage based on traffic demand. In order to investigate its applicability at signalized intersections in Japan, an intersection located in Yokkaichi City of Mie Prefecture was selected as an experimental application site by the Japan Universal Traffic Management Society (UTMS. Based on the data collected at the intersection before and after implementing the group-based control policy respectively, this study evaluated the impacts of such a policy on driver behavior and intersection safety. To specify those impacts, a few models utilizing cycle-based data were first developed to interpret the occurrence probability and rate of red-light-running (RLR. Furthermore, analyses were performed on the yellow-entry time (Ye of the last cleared vehicle and post encroachment time (PET during the phase switching. Conclusions supported that the group-based control policy, along with certain other factors, directly or indirectly influenced the RLR behavior of through and right-turn traffics. Meanwhile, it has potential safety benefits as well, indicated by the declined Ye and increased PET values.

    In this paper we capture and synthesize the unique knowledge of experts so that choices regarding policy measures to address methamphetamine consumption and dependency in Australia can be strengthened. We examine perceptions of the: (1) influence of underlying factors that impact on the methamphetamine problem; (2) importance of various models of intervention that have the potential to affect the success of policies; and (3) efficacy of alternative pseudoephedrine policy options. We adopt a multi-criteria decision model to unpack factors that affect decisions made by experts and examine potential variations on weight/preference among groups. Seventy experts from five groups (i.e. academia (18.6%), government and policy (27.1%), health (18.6%), pharmaceutical (17.1%) and police (18.6%)) in Australia participated in the survey. Social characteristics are considered the most important underlying factor, prevention the most effective strategy and Project STOP the most preferred policy option with respect to reducing methamphetamine consumption and dependency in Australia. One-way repeated ANOVAs indicate a statistically significant difference with regards to the influence of underlying factors (F(2.3, 144.5)=11.256, pmethamphetamine consumption and dependency. Most experts support the use of preventative mechanisms to inhibit drug initiation and delayed drug uptake. Compared to other policies, Project STOP (which aims to disrupt the initial diversion of pseudoephedrine) appears to be a more preferable preventative mechanism to control the production and subsequent sale and use of methamphetamine. This regulatory civil law lever engages third parties in controlling drug-related crime. The literature supports third-party partnerships as it engages experts who have knowledge and expertise with respect to prevention and harm minimization. Copyright © 2016 Elsevier B.V.

    2012-09-01

    Full Text Available BACKGROUND: Absence of an effective tobacco control policy costs lives and tobacco prevention is policy-sensitive. We describe the historical record of tobacco control in France. METHODS: Public policies and main decisions (laws, regulations, health plans for tobacco control were considered from 1950 to 2010. Data for cigarette sales and relative price of cigarettes were obtained from official databases. Sales are expressed in number of cigarettes. The relative price of cigarettes is the nominal price divided by the Consumer Price Index. RESULTS: The first step Veil Law (1976 blunted the steady increase in cigarette sales observed since World War II. The second period began with the Evin Law (1991. This law banned tobacco advertising and withdrew tobacco from the Consumer Price Index allowing for marked and repeated increases in taxes. Sales decreased over the next 6 years, from 97.1 billion to 83.0 billion in 1997 but then remained steady for 5 years (83.5 billion in 2001. The first Cancer Plan (2003 imposed three tax increases in a year (39% increase in price. Cigarette sales decreased to 54.9 billion in 2004. This period ended in 2004 when a moratorium on tobacco taxes was announced. The policies which have been implemented since President Sarkozy was elected in 2007 were flawed and protected the interests of the tobacco industry: prevalence of smoking is now increasing, mainly among the younger generation. Since 1991, the cigarette market has nearly halved but the decline has been a stop-and-go erratic process. The two 5-year periods (1997-2002 and 2005 -2010 during which consumption leveled off seem to demonstrate that government-driven health policies could have been influenced by commercial interests. CONCLUSION: Tobacco control efforts, especially tobacco tax increases, need to be sustained and shielded from the influence of the tobacco industry.

    Pharmaceutical drug poisonings, especially those that are intentional, are a serious problem for adolescents and young adults. Poison control center data is a viable tool to track intentional drug poisonings in near real-time. To determine intentional drug poisoning rates among adolescents and young adults in Ohio using poison control center data. We analyzed data from 2002 to 2014 obtained by Ohio's three poison control centers. Inclusion variables were calls made to the centers that had appropriate subject age (10-29 years old), subject sex, involved substance (all drug classes), and medical outcome (no effect, minor effect, moderate effect, major effect, and death). Intentional drug poisoning reports were also separated into subgroups to compare suspected suicide reports to misuse and abuse reports. Finally, resident population estimates were used to generate 2014 intentional drug poisoning rates for each county in Ohio. The most common age group for intentional drug poisonings was 18-24. Females reported more suspected suicide drug poisonings while males reported more misuse/abuse drug poisonings. The most reported drug class across all ages was analgesics. Of the 88 counties in Ohio, Hamilton, Williams, Washington, and Guernsey counties had the highest rates of intentional drug poisonings. The high report rate of suspected suicides and analgesic class drugs demonstrates the need for preventative measures for adolescents and young adults in Ohio. Any interventions, along with legislative changes, will need to take place in our local communities.

    Introduction Smoking remains the leading cause of preventable death in the USA but can be reduced through policy interventions. Computational models of smoking can provide estimates of the projected impact of tobacco control policies and can be used to inform public health decision making. We outline a protocol for simulating the effects of tobacco policies on population health outcomes. Methods and analysis We extend the Smoking History Generator (SHG), a microsimulation model based on data from the National Health Interview Surveys, to evaluate the effects of tobacco control policies on projections of smoking prevalence and mortality in the USA. The SHG simulates individual life trajectories including smoking initiation, cessation and mortality. We illustrate the application of the SHG policy module for four types of tobacco control policies at the national and state levels: smoke-free air laws, cigarette taxes, increasing tobacco control programme expenditures and raising the minimum age of legal access to tobacco. Smoking initiation and cessation rates are modified by age, birth cohort, gender and years since policy implementation. Initiation and cessation rate modifiers are adjusted for differences across age groups and the level of existing policy coverage. Smoking prevalence, the number of population deaths avoided, and life-years gained are calculated for each policy scenario at the national and state levels. The model only considers direct individual benefits through reduced smoking and does not consider benefits through reduced exposure to secondhand smoke. Ethics and dissemination A web-based interface is being developed to integrate the results of the simulations into a format that allows the user to explore the projected effects of tobacco control policies in the USA. Usability testing is being conducted in which experts provide feedback on the interface. Development of this tool is under way, and a publicly accessible website is available at http

    Highlights: ► We examined the kinetics of ferromagnetic drugs by simulation. ► We tried to accumulate the magnetic drug in the target part by rotating a magnet. ► Ferromagnetic drugs were accumulated in the target part along the rotating axis. ► Ferromagnetic drugs could be swept downstream in the off-axis part. -- Abstract: In order to solve the problems of the side effects and medical lowering, has been advanced a study on the drug delivery system (DDS) to accumulate the drugs locally in the body with minimum dosage. The DDS is a system that controls the drug kinetics in the body precisely and accumulates the drug locally at the target part, keeping the drugs at high density. Among the DDS, the magnetic drug delivery system (MDDS) is the one that we studied. This is a technique to accumulate drugs by using the magnetic force as the physical driving force. Our previous researches showed the possibility of the technique of MDDS to accumulate the drugs with higher accumulation rate and locality than the traditional methods. It is necessary to apply a strong external magnetic field and a high magnetic gradient to accumulate the ferromagnetic drugs at a deep diseased part non-invasively. However, by applying a static magnetic field from one direction, the drug accumulates only at the surface of the body locates near the magnet. In this study, we tried to change the magnetic field applied by a superconducting bulk magnet with time, in order to make a constant and strong magnetic field applied in the center of the body and to accumulate the ferromagnetic drugs at the deep target part in the body. First of all, the effect of the surface treatment of the ferromagnetic drugs to prevent its absorption in the normal tissue was examined. Then, to increase the accumulation rate of the ferromagnetic drugs at the target part, the distribution of magnetic field was changed, and the optimum spatial and temporal conditions of magnetic field were examined

    To examine the salience of tobacco marketing on postsecondary campuses and student support for tobacco control policies. Face-to-face surveys were conducted with 1690 students at 3 universities in southwestern Ontario. Virtually all (97%) students reported noticing tobacco marketing in the past year, and 35% reported noticing marketing on campus. There was strong support for smoke-free restrictions on campus, including restaurants and bars (82%), and for prohibitions on campus marketing. The presence of campus policies was associated with reduced exposure to marketing and increased policy support. There is strong support among students to remove tobacco marketing from campus and to introduce comprehensive smoke-free restrictions.

  2. Sol-gel encapsulation for controlled drug release and biosensing

    Science.gov (United States)

    Fang, Jonathan

    The main focus of this dissertation is to investigate the use of sol-gel encapsulation of biomolecules for controlled drug release and biosensing. Controlled drug release has advantages over conventional therapies in that it maintains a constant, therapeutic drug level in the body for prolonged periods of time. The anti-hypertensive drug Captopril was encapsulated in sol-gel materials of various forms, such as silica xerogels and nanoparticles. The primary objective was to show that sol-gel silica materials are promising drug carriers for controlled release by releasing Captopril at a release rate that is within a therapeutic range. We were able to demonstrate desired release for over a week from Captopril-doped silica xerogels and overall release from Captopril-doped silica nanoparticles. As an aside, the antibiotic Vancomycin was also encapsulated in these porous silica nanoparticles and desired release was obtained for several days in-vitro. The second part of the dissertation focuses on immobilizing antibodies and proteins in sol-gel to detect various analytes, such as hormones and amino acids. Sol-gel competitive immunoassays on antibody-doped silica xerogels were used for hormone detection. Calibration for insulin and C-peptide in standard solutions was obtained in the nM range. In addition, NASA-Ames is also interested in developing a reagentless biosensor using bacterial periplasmic binding proteins (bPBPs) to detect specific biomarkers, such as amino acids and phosphate. These bPBPs were doubly labeled with two different fluorophores and encapsulated in silica xerogels. Ligand-binding experiments were performed on the bPBPs in solution and in sol-gel. Ligand-binding was monitored by fluorescence resonance energy transfer (FRET) between the two fluorophores on the bPBP. Titration data show that one bPBP has retained its ligand-binding properties in sol-gel.

    Objectives In 2009, the Chinese government launched a national healthcare reform programme aiming to control healthcare expenditure and increase the quality of care. As part of this programme, a new drug pricing reform was initiated on 1 June 2015. The objective of this study was to describe the changing landscape of drug pricing policy in China and analyse the potential impact of the reform. Methods The authors conducted thorough research on the drug pricing reform using three Chinese databases (CNKI, Wanfang, and Weipu), Chinese health authority websites, relevant press releases, and pharmaceutical blogs and discussion forums. This research was complemented with qualitative research based on targeted interviews with key Chinese opinion leaders representing the authorities’ and prescribers’ perspectives. Results With the current reform, the government has attempted to replace its direct control over the prices of reimbursable drugs with indirect, incentive-driven influence. Although the exact implementation of the reform remains unclear at the moment, the changes introduced so far and the pilot project designs indicate that China is considering adaptation of some form of internal and external reference pricing policies, commonly used in the Organisation for Economic Co-operation and Development countries. Several challenges related to the potential new mechanism were identified: 1) the risk of hospital underfunding, if hospital funding reform is not prioritised; 2) the risk of promoting the use of cheap, low-quality drugs, if a reliable quality control system is not in place and discrepancy between the available drugs is present; 3) the risk of increasing disparity in access to care between poor and rich regions, in case of country-wide price convergence; and 4) the risk of industry underinvestment, resulting in reduced competition, issues with quality and sustainability of supply, and potentially negative social impact. Conclusions Foreign pricing policies

    To uptake and release hydrophilic model drugs and insulin in a novel conductive polymer (CP) nanotube transdermal patch. The externally controlled transdermal delivery of model drugs and insulin were tested ex vivo and results were compared with CP films. The unique intrinsic properties of CPs provide electrostatic interaction between the model drugs and polymer backbone. When a pulsed potential was applied, the drug delivery release profile mimics that of injection delivery. With a constant potential applied, the release rate constants of the patch system were up to three-times faster than the control (0 V) and released approximately 80% more drug molecules over 24 h. The CP nanotube transdermal patch represents a new and promising drug method, specifically for hydrophilic molecules, which have been a large obstacle for conventional transdermal drug delivery systems.

    Although valuable, national opinion surveys on alcohol policy may be less informative for policy development at the local level. Using samples of adult residents in 2 college communities, the present study: (1) measured public support for local alcohol control policies to stem underage drinking and alcohol overservice in on-premise outlets, (2) assessed residents' opinions regarding neighborhood problems, and (3) identified factors associated with strong policy support. We administered random-sample telephone surveys to residents aged 21 years and older in college communities located in Community 1 (N = 501; mean age = 57.4 years, SD = 14.7) and Community 2 (N = 505; mean age = 56.0 years, SD = 15.2). The response rates were typical of telephone surveys (Community 1: 33.5%; Community 2: 29.9%). We assessed support for 16 alcohol control policies and the occurrence of specific types of neighborhood incidents (e.g., witnessing intoxicated people). We used multiple regression analyses to determine factors associated with policy support. Residents in Community 1 reported significantly higher weekly alcohol use, a greater number of witnessed neighborhood incidents, and a higher level of perceived neighborhood problems than did residents in Community 2. Residents in Community 1 perceived local alcohol control policies and their enforcement to be significantly stricter. Overall, policy support was high and did not differ between the communities. In both communities, higher policy support was significantly associated with being female, being older, less weekly alcohol use, and lower perceived strictness of alcohol control policies and enforcement. It is important for campus officials and community leaders to be aware of and publicize favorable public opinion when advocating for policy change, especially at the local level. Information on residents' perceptions of the neighborhood issues they face can also inform local policy and enforcement efforts.

  6. Tobacco-control policies in tobacco-growing states: where tobacco was king.

    Science.gov (United States)

    Fallin, Amanda; Glantz, Stanton A

    2015-06-01

    POLICY POINTS: The tobacco companies prioritized blocking tobacco-control policies in tobacco-growing states and partnered with tobacco farmers to oppose tobacco-control policies. The 1998 Master Settlement Agreement, which settled state litigation against the cigarette companies, the 2004 tobacco-quota buyout, and the companies' increasing use of foreign tobacco led to a rift between the companies and tobacco farmers. In 2003, the first comprehensive smoke-free local law was passed in a major tobacco-growing state, and there has been steady progress in the region since then. Health advocates should educate the public and policymakers on the changing reality in tobacco-growing states, notably the major reduction in the volume of tobacco produced. The 5 major tobacco-growing states (Kentucky, North Carolina, South Carolina, Tennessee, and Virginia) are disproportionately affected by the tobacco epidemic, with higher rates of smoking and smoking-induced disease. These states also have fewer smoke-free laws and lower tobacco taxes, 2 evidence-based policies that reduce tobacco use. Historically, the tobacco farmers and hospitality associations allied with the tobacco companies to oppose these policies. This research is based on 5 detailed case studies of these states, which included key informant interviews, previously secret tobacco industry documents (available at http://legacy.library.ucsf.edu), and media articles. This was supplemented with additional tobacco document and media searches specifically for this article. The tobacco companies were particularly concerned about blocking tobacco-control policies in the tobacco-growing states by promoting a pro-tobacco culture, beginning in the late 1960s. Nevertheless, since 2003, there has been rapid progress in the tobacco-growing states' passage of smoke-free laws. This progress came after the alliance between the tobacco companies and the tobacco farmers fractured and hospitality organizations stopped opposing smoke

    In the last 12 months, many more cases of alcohol and drug (substance) abuse in the workplace were seen in the Escravos operations of Chevron Nigeria Limited than in previous years. This called the attention to the rising prevalence of drug and alcohol abuse in contradistinction to reports from similar organizations in other parts of the world. Chevron Nigeria has a written Drug and Alcohol Policy which has been dormant for some time because of the apparent rarity of the problem of substance abuse in the workplace. This Policy is being reviewed to broaden its scope and make it more effective. A total of 30 employees were tested for drugs and alcohol .6 exceeded the legal limits of Blood Alcohol Concentration (BAC) and 5 tested positive for drugs. Tests were mainly post-accident, reasonable cause and random. The common substances abused were alcohol, cannabis, cocaine and morphine in that order. The findings are compared with those of similar organizations in UK and USA. Efforts to control substance abuse in the workplace are being put into place.

    Full Text Available To achieve the goals of national sustainable development, the peaking control of CO2 emissions is pivotal, as well as other pollutants. In this paper, we build a Chinese inter-regional CGE model and simulate 13 policies and their combinations. By analyzing the energy consumptions, coal consumptions, relating emissions and their impacts on GDP, we found that with the structure adjustment policy, the proportion of coal in primary fossil fuels in 2030 will decrease from 53% to 48% and CO2 emissions will decrease by 11.3%–22.8% compared to the baseline scenario. With the energy intensity reduction policy, CO2 emissions will decrease by 33.3% in 2030 and 47.8% in 2050 than baseline scenario. Other pollutants will also be controlled as synergetic effects. In this study we also find that although the earlier the peaking time the better for emission amounts control, the economic costs can not be ignored. The GDP will decrease by 2.96%–8.23% under different scenarios. Therefore, integrated policy solutions are needed for realizing the peaks package and more targeted measures are required to achieve the peaks of other pollutants earlier.

    Biochemistry drug, at present, is still the main tool that human struggle to defeat the diseases. So, developing safe and efficacious technique of drug targeting delivery and controlled release is key to enhance curative effect, decrease drug dosage, and lessen its side effect. Drug-loaded nanoparticles, which is formed by conjugate between nanotechnology and modern pharmaceutics, is a new fashioned pharmic delivery carrier. Because of advantages in pharmic targeting transport and controlled or slow release and improving bioavailability, it has been one of developing trend of modern pharmaceutical dosage forms

    Modifications of endhydroxylated poly(dimethylsiloxane) (PDMS) formulations were studied for their ability to be applied onto tablet cores in a spray-coating process and to control drug release in zero-order fashion. Modifications of the crosslinker from the most commonly used tetraethylorthosilicate (TEOS) to the trifunctional 3-(2,3-epoxypropoxy)propyltrimethoxysilane (SIG) and a 1:1 mixture of the two were undertaken. Addition of methylpolysiloxane-copolymers were studied. Lactose, microcrystalline cellulose (MCC) and polyethylene glycol 8000 (PEG) were the channeling agents applied. The effects on dispersion properties were characterized by particle size distribution and viscosity. Mechanical properties of resulting free films were studied to determine applicability in a pan-coating process. Release of hydrochlorothiazide (marker drug) was studied from tablets coated in a lab-size conventional coating pan. All dispersions were found suitable for a spray-coating process. Preparation of free films showed that copolymer addition was not possible due to great decline in mechanical properties. Tablets coated with formulations containing PEG were most suitable to control drug release, at only 5% coating weight. Constant release rates could be achieved for formulations with up to 25% PEG; higher amounts resulted in a non-linear release pattern. Upon adding 50% PEG, a drug release of 63% over 24 h could be achieved.

    According to World Health Organisation figures, 30% of all cancer deaths, 20% of all coronary heart diseases and strokes and 80% of all chronic obstructive pulmonary disease are caused by cigarette smoking. Environmental Tobacco Smoke (ETS) exposure has also been shown to be associated with disease and premature death in non-smokers. In response to this environmental health issue, several countries have brought about a smoking ban policy in public places and in the workplace. Countries such as the U.S., France, Italy, Ireland, Malta, the Netherlands, Sweden, Scotland, Spain, and England have all introduced policies aimed at reducing the population exposure to ETS. Several investigations have monitored the effectiveness of these smoking ban policies in terms of ETS concentrations, human health and smoking prevalence, while others have also investigated a number of alternatives to smoking ban policy measures. This paper reviews the state of the art in research, carried out in the field of ETS, smoking bans and Tobacco Control to date and highlights the need for future research in the area.

    Full Text Available BACKGROUND: In most countries of Sub-Saharan Africa, control of lymphatic filariasis (LF is based on annual mass drug administration (MDA with a combination of ivermectin and albendazole. Treatment coverages are however often suboptimal for programmes to reach the goal of transmission interruption within reasonable time. The present study aimed to identify predictors and barriers to individual drug uptake during MDA implementation by the National LF Elimination Programme in Tanzania. METHODS: A questionnaire based cross sectional household survey was carried out in two rural and two urban districts in Lindi and Morogoro regions shortly after the 2011 MDA. 3279 adults (≥15 years were interviewed about personal characteristics, socio-economic status, MDA drug uptake among themselves and their children, reasons for taking/not taking drugs, and participation in previous MDA activities for LF control. FINDINGS: The overall drug uptake rate was 55.1% (range of 44.5-75.6% between districts. There was no overall major difference between children (54.8% and adults (55.2% or between females (54.9% and males (55.8%, but the role of these and other predictors varied to some extent between study sites. Major overall predictors of drug uptake among the interviewed adults were increasing age and history of previous drug uptake. Being absent from home during drug distribution was the main reason for not taking the drugs (50.2% followed by clinical contraindications to treatment (10.8%, missing household visits of drug distributors (10.6%, and households not being informed about the distribution (9.0%. CONCLUSION: Drug uptake relied more on easily modifiable provider-related factors than on individual perceptions and practices in the target population. Limited investments in appropriate timing, dissemination of accurate timing information to recipients and motivation of drug distributors to visit all households (repeatedly when residents are absent are likely

    Current approaches to encapsulate and deliver therapeutic compounds have focused on developing liposomal and biodegradable polymeric nanoparticles (NPs), resulting in clinically approved therapeutics such as Doxil/Caelyx and Genexol-PM, respectively. Our group recently reported the development of biodegradable core-shell NP systems that combined the beneficial properties of liposomal and polymeric NPs for controlled drug delivery. Herein we report the parameters that alter the biological and physicochemical characteristics, stability, drug release properties and cytotoxicity of these core-shell NPs. We further define scalable processes for the formulation of these NPs in a reproducible manner. These core-shell NPs consist of (i) a poly(D,L-lactide-co-glycolide) hydrophobic core, (ii) a soybean lecithin monolayer, and (iii) a poly(ethylene glycol) shell, and were synthesized by a modified nanoprecipitation method combined with self-assembly. Preparation of the NPs showed that various formulation parameters such as the lipid/polymer mass ratio and lipid/lipid-PEG molar ratio controlled NP physical stability and size. We encapsulated a model chemotherapy drug, docetaxel, in the NPs and showed that the amount of lipid coverage affected its drug release kinetics. Next, we demonstrated a potentially scalable process for the formulation, purification, and storage of NPs. Finally, we tested the cytotoxicity using MTT assays on two model human cell lines, HeLa and HepG2, and demonstrated the biocompatibility of these particles in vitro. Our data suggest that the PLGA-lecithin-PEG core-shell NPs may be a useful new controlled release drug delivery system.

    Brazilian public policy on drugs has been permeated by two diametrically opposing approaches: one focusing on prohibition and the other on non- prohibition. Similarly, there have been two opposing approaches to mental healthcare, one centered on hospitalization and the other psychosocial care and development. In the context of these different paradigms, this article presents an analysis of twenty-two documents sourced by the legislative rules over the last sixteen years. After the year 2000, a renewed focus by healthcare community on drugs was noticeable as was the immersion of a harm reducing approach. Following international trends, although there are still considerable divergencies between (a) psychosocial care and(b) residential care in the therapeutic communities there seems to be an alignment to anti- prohibition approaches.

    The synthesis of nanogels as devices capable to maintain the drug level within a desired range for a long and sustained period of time is a leading strategy in controlled drug delivery. However, with respect to the good results obtained with antibodies and peptides there are a lot of problems related to the quick and uncontrolled diffusion of small hydrophilic molecules through polymeric network pores. For these reasons research community is pointing toward the use of click strategies to reduce release rates of the linked drugs to the polymer chains. Here we propose an alternative method that considers the electrostatic interactions between polymeric chains and drugs to tune the release kinetics from nanogel network. The main advantage of these systems lies in the fact that the carried drugs are not modified and no chemical reactions take place during their loading and release. In this work we synthesized PEG-PEI based nanogels with different protonation degrees and the release kinetics with charged and uncharged drug mimetics (sodium fluorescein, SF, and rhodamine B, RhB) were studied. Moreover, also the effect of counterion used to induce protonation was taken into account in order to build a tunable drug delivery system able to provide multiple release rates with the same device. - Highlights: • The design of nanogels as drug delivery systems based on electrostatic interaction among drug and polymers is proposed. • Nanogels can be synthetized tuning their positive charge density, according to the protonation of PEI at different pH. • No biorthogonal chemistry strategies are applied to the polymers or drugs. • Drug release is efficiently modulated by charge density of PEI chains. • The effect of counterion on nanogel synthesis is investigated and allows controlling the drug release.

    Full Text Available Na história de democratização das políticas de saúde, um dos campos que construiu visibilidade aos movimentos de saúde, quer pela denúncia das "ausências e omissões" dos serviços instalados, quer pela luta no sentido de construir um espaço regular para o exercício do controle nos serviços e nas burocracias da gestão da saúde, foi o controle social da coisa pública. No início da década de 80, a experiência marcante na região leste da cidade de São Paulo foi a de criar os conselhos de saúde como representação popular no controle do Estado. Nesta reflexão, as autoras não pretendem discutir a composição da representação, mas sim avançar para novos problemas. Na conjuntura pós Constituição de 1988, vivemos um novo momento democrático. As leis, a princípio, amparam a participação da população nas políticas de saúde e são defensoras dos direitos sociais. Como, então, é entendido o campo do controle social? Este restringe-se aos serviços de saúde ou é mais ampliado, englobando a política de saúde? Como é que as leis passam da sua formulação para a sua aplicação? Busca-se, no texto, mapear questões que se colocam quando o controle social se orienta para constituir uma pressão pela mudança/alteração da situação.As the democratization of health policies develops, social control over public interests has been of help in providing health movements with prominence, not only by denouncing cases of "negligence and omission" by established services, but also by struggling to create regular, favourable conditions by which to exercise control over services and governmental management of public health policies. In the early 1980s, a remarkable experience occurred in the "Zona Leste" or eastern burrough of the city of São Paulo, consisting of the emergence of Health Councils as a means of popular representation in the control over the state.

    In recent years, the Thai government has strengthened drug law enforcement as a strategy to address a continuing epidemic of illicit drug use. We sought to assess temporal trends in street-level availability of illicit drugs among injection drug users (IDUs) in Bangkok, Thailand. Using univariate statistics and multivariate logistic regression, we assessed changes in the availability of five substances (heroin, methamphetamine, crystal methamphetamine, midazolam, and illicit methadone) between 2009 and 2011 and examined social, structural and individual factors influencing availability among community-recruited samples of IDUs in Bangkok. Availability was measured in three levels: immediate (available in ≤10 min); moderate (available in 10-90 min); and delayed (available in >90 min; our reference category). The analyses included 718 IDUs, including 165 (23.0%) women. Controlling for changes in participant characteristics between assessments, and in a period of constant nominal illicit drug prices, moderate availability of all substances increased significantly between 2009 and 2011, with adjusted odds ratios ranging between 2.36 (illicit methadone) and 4.61 (crystal methamphetamine) (all pdrug suppression efforts, the availability of illicit drugs among IDUs in Bangkok increased significantly between 2009 and 2011. The findings raise concern about the overreliance on drug law enforcement-based approaches and point to the need for greater investment in evidence-based drug policies.

    We investigated whether changes in perinatal outcomes occurred following introduction of key tobacco control policies in the Netherlands: smoke-free legislation in workplaces plus a tobacco tax increase and mass media campaign (January-February 2004); and extension of the smoke-free law to the hospitality industry, accompanied by another tax increase and mass media campaign (July 2008). This was a national quasi-experimental study using Netherlands Perinatal Registry data (2000-2011; registration: ClinicalTrials.gov NCT02189265). Primary outcome measures were: perinatal mortality, preterm birth, and being small-for-gestational age (SGA).

    Warfarin, commonly used anticoagulant in clinic, has serious shortcomings due to its unsatisfactory pharmacodynamics. One of the efficient ways for the improvement of pharmacological and consumer properties of drugs is the development of optimal drug delivery systems. The aim of this work is to synthesize novel warfarin - silica composites and to study in vitro the drug release kinetics to obtain the composites with controlled release. The composites of warfarin with unmodified (UMS) and mercaptopropyl modified silica (MPMS) were synthesized by sol-gel method. The composite formation was confirmed by FTIR spectra. The concentrations of warfarin released to media with pH 1.6, 6.8 and 7.4 were measured using UV spectroscopy. The drug release profiles from the solid composites were described by a series of kinetic models which includes zero order kinetics, first order kinetics, the modified Korsmeyer-Peppas model and Hixson-Crowell model. The synthesized sol-gel composites have different kinetic behavior in the studied media. In contrast to the warfarin composite with unmodified silica, the drug release from the composite with mercaptopropyl modified silica follows zero order kinetics for 24 h irrespective to the release medium pH due to mixed mechanism (duffusion + degradation and/or disintegration of silica matrix). The obtained results showed that warfarin - silica sol-gel composites have a potential application for the development of novel oral formulation of the drug with controlled delivery.

    2009-11-01

    Faced with a rising HIV epidemic among injecting drug users, harm reduction policies and programs were introduced in Malaysia in 2005. The positive impact seen since the introduction of these programs comprise the inclusion of the health aspects of illicit drug use in the country's drug policies; better access to antiretroviral therapy for injecting drug users who are HIV infected; reduction in HIV-risk behavior; and greater social benefits, including increased employment. Despite these achievements, tension between law enforcement and public health persists, as harm reduction exists alongside an overall drug policy that is based on abstinence and zero tolerance. Unless there is harmonization of this policy, sustainability and scale-up of harm reduction programs will remain a challenge.

  8. Articulating addiction in alcohol and other drug policy: A multiverse of habits.

    2016-05-01

    Concepts of addiction differ across time and place. This article is based on an international research project currently exploring this variation and change in concepts of addiction, in particular in the field of alcohol and other drug (AOD) use. Taking AOD policy in Australia and Canada as its empirical focus, and in-depth interviews with policy makers, service providers and advocates in each country as its key method (N=60), the article compares the addiction concepts articulated by professionals working in each setting. Drawing on Bruno Latour's theoretical work on the body and his proposal for a better science based on the 'articulation of differences', it explores the accounts of addiction offered across the Australian and Canadian project sites, identifying a shared dynamic in all: the juggling of difference and unity in discussions of the nature of addiction, its composite parts and how best to respond to it. The article maps two simultaneous trajectories in the data - one moving towards difference in participants' insistence on the multitude and diversity of factors that make up addiction problems and solutions, and the other towards unity in their tendency to return to narrow disease models of addiction in uncomfortable, sometimes dissonant, strategic choices. As I will argue, the AOD professionals interviewed for my project operate in two modes treated as distinct in Latour's proposal: in turning to reifying disease labels of addiction they take for granted, and work within, a 'universe of essences', but in articulating the multiplicity and diversity of addiction, they grope towards a vision of a 'multiverse of habits'. The article concludes by addressing this tension directly, scrutinising its practical implications for the development of policy and delivery of services in the future, asking how new thinking, and therefore new opportunities, might be allowed to emerge.

  9. Pharmaceutical policies for the Third World--whose responsibility?

    1983-07-16

    Several developing countries, such as Bangladesh, Cuba, India, and Mozambique, are currently formulating national pharmaceutical policies to reduce expenditures on drugs while increasing their availability to those in greatest need. 5 components of such national policies have been identified: 1) elimination of ineffective and inappropriate preparations through concentrating on a selection such as the World Health Organization's 200 "basic and essential drugs", coupled with national drug pricing policies that discriminate between essential drugs and non-essential or luxury drugs; 2) public systems of drug distribution which would reduce costs to the consumer; 3) importation of the limited number of drugs distributed through the public system in bulk, which might reduce costs by 20-25%; 4) use of generic rather than brand name drugs; and 5) establishment of domestic pharmaceutical industries within developing countries to encourage research into drugs for local health problems, reduce use of foreign exchange to import drugs, and increase local self-reliance in dealing with disease. In November 1982, Health Action International, a coordinating body for more than 50 publish interest groups seeking to promote rational use of pharmaceuticals, presented a draft internationl code on pharmaceuticals to the UN Conference on Trade and Development. A voluntary code produced in 1981 by the International Federation of Pharmaceutical Manufacturers' Associations paid little attention to monitoring and enforcement. Little progress has been made, and the need for sensible policy making at the international and national levels has long been apparent.

    Coal is not only an important energy source in China but also a major source of air pollution. Because of this, China's national sulfur dioxide (SO(2)) emissions have been the highest in the world for many years, and since the 1990s, the territory of China's south and southwest has become the third largest acid-rain-prone region in the world. In order to control SO(2) emissions, the Chinese government has formulated and promulgated a series of policies and regulations, but it faces great difficulties in putting them into practice. In this retrospective look at the history of SO(2) control in China, we found that Chinese SO(2) control policies have become increasingly strict and rigid. We also found that the environmental policies and regulations are more effective when central officials consistently give environmental protection top priority. Achieving China's environmental goals, however, has been made difficult by China's economic growth. Part of this is due to the practice of environmental protection appearing in the form of an ideological "campaign" or "storm" that lacks effective economic measures. More recently, better enforcement of environmental laws and regulations has been achieved by adding environmental quality to the performance assessment metrics for leaders at all levels. To continue making advances, China needs to reinforce the economic and environmental assessments for pollution control projects and work harder to integrate economic measures into environmental protection. Nonetheless, China has a long way to go before economic growth and environmental protection are balanced.

  14. Conductive polymer nanotube patch for fast and controlled in vivo transdermal drug delivery

    Science.gov (United States)

    Nguyen, Thao M.

    Transdermal drug delivery has created new applications for existing therapies and offered an alternative to the traditional oral route where drugs can prematurely metabolize in the liver causing adverse side effects. Opening the transdermal delivery route to large hydrophilic drugs is one of the greatest challenges due to the hydrophobicity of the skin. However, the ability to deliver hydrophilic drugs using a transdermal patch would provide a solution to problems of other delivery methods for hydrophilic drugs. The switching of conductive polymers (CP) between redox states cause simultaneous changes in the polymer charge, conductivity, and volume—properties that can all be exploited in the biomedical field of controlled drug delivery. Using the template synthesis method, poly(3,4-ethylenedioxythiophene (PEDOT) nanotubes were synthesized electrochemically and a transdermal drug delivery patch was successfully designed and developed. In vitro and in vivo uptake and release of hydrophilic drugs were investigated. The relationship between the strength of the applied potential and rate of drug release were also investigated. Results revealed that the strength of the applied potential is proportional to the rate of drug release; therefore one can control the rate of drug release by controlling the applied potential. The in vitro studies focused on the kinetics of the drug delivery system. It was determined that the drug released mainly followed zero-order kinetics. In addition, it was determined that applying a releasing potential to the transdermal drug delivery system lead to a higher release rate constant (up to 7 times greater) over an extended period of time (˜24h). In addition, over 24 hours, an average of 80% more model drug molecules were released with an applied potential than without. The in vivo study showed that the drug delivery system was capable of delivering model hydrophilic drugs molecules through the dermis layer of the skin within 30 minutes

    To assess the impact of a tobacco control law adopted in Albania in 2007 and to estimate the share of illicit cigarettes on the market. Comparative analysis of two waves of a nationally representative household survey, one conducted before the new law went into effect and the other after 2 years. Official sales data were contrasted with the consumption estimate based on the survey. Smoking prevalence, quit attempts, exposure to cigarette advertising, exposure to second-hand smoke, total cigarette consumption, share of illicit packs among packs possessed by smokers. Despite the adoption of strong smoke-free policies and adverting restrictions, smoking prevalence in Albania has risen. The increase in prevalence has been driven by higher smoking rates among females (18.9% in 2007 vs 29.3% in 2009) and young adults (23.2% in 2007 vs 38.5% in 2009 among 18-19 year olds). Self-reported exposure to second-hand smoke and cigarette advertising have been reduced since 2007. The majority of respondents are still exposed to second-hand smoke and more than half are exposed to tobacco advertising. Nevertheless, there are signs that the consumption of illicit cigarettes is declining. The impacts of smoke-free policies and an advertising ban have been limited due to lack of enforcement and failure to adopt a comprehensive set of tobacco control measures. These measures should include sizeable and regular tobacco tax increases in excess of the general level of inflation and income growth. The decline in the share of illicit cigarettes should improve the effectiveness of the cigarette tax policy.

    Not much information is available on workplace drug testing (WDT) in Europe. There is no specific legislation and there are no generally accepted guidelines. Many companies establish a drug policy with little or no provisions for drug testing. Often, testing is performed on-site by occupational physicians, with little or no quality control, no systematic confirmation of positives, no chain of custody and no adulteration testing. In some parts of Europe, e.g. in the United Kingdom and some Scandinavian countries, WDT is increasing in importance, but it is not as widespread as in USA. The most frequently performed tests are amphetamines, cannabinoids, cocaine, opiates and alcohol. The percentage of positives is variable, but seems to decrease with the years following the introduction of WDT. Cannabis is the drug that is most frequently found.Recently, the European Workplace Drug Testing Society (EWDTS) was founded, with the aims to ensure that WDT in Europe is performed to a defined quality standard and in a legally secured way and to provide an independent forum for all aspects of WDT.A working group in the United Kingdom has recently finalised the United Kingdom laboratory guidelines for legally defensible WDT and discussions are under way with the EWDTS to establish common guidelines. Many efforts will be needed to establish WDT as an accepted part of a company policy on drugs: establishing and maintaining the confidence in the results of the laboratory, establishing the legal status of WDT, preserving the privacy and rights of the employees, proving the cost-effectiveness of WDT in a European context, finding a balance between strict guidelines and enough flexibility to tailor testing to the changing needs. It is hoped that the exchange of experience between different countries will contribute to reaching these goals.

    Full Text Available Purpose: The purpose of this study is to identify effective strategies used by Alabama hospitals to manage drug shortages. Moreover, this study aims to determine if there are any relationships among hospital size, utilization of a standard policy for drug shortage management and perceived usefulness of standard procedures for drug shortages. Methods: A paper survey was mailed to 129 hospital pharmacies in Alabama (per the Alabama Hospital Association directory. The survey consisted of 5 demographic questions, questions involving perception of current medication shortages, sources of information about shorted drugs, and frequency of discussion at P&T committee meetings. Most importantly, the survey contained questions about the use of a standard policy for handling drug shortages, the effectiveness of the policy if one is used, and an open-ended question asking the recipient to describe the policy being used. Results: A response rate of 55% was achieved as 71 surveys were completed and returned. Approximately 70% of the survey respondents described the current drug shortage issue as a top priority in their pharmacy department. The pharmacy distributor served as the primary source of information regarding drug shortages for 45% of the facilities. There is a direct relationship between size of hospital and likelihood of utilization of a standard policy or procedure for drug shortage management among the sample. The smaller facilities of the sample perceived their management strategies as effective more frequently than the larger hospitals. Conclusion: Common components of effective management strategies included extensive communication of shortage details and the ability to locate alternative products. The use of portable technology (e.g., Smart phones and tablets along with mobile applications may emerge as popular means for communicating drug product shortage news and updates within a facility or healthcare system.   Type: Original Research

  20. Least bad solutions to the 'drugs problem'.

    Mugford, S

    1991-01-01

    This paper examines the current difficulties being faced in Australia by policy-makers attempting to regulate the non-medical use of illegal drugs, and it is suggested that the difficulties centre upon two aspects. First, existing prohibitions are unsuccessful, with use levels rising and, in some arenas (e.g. cocaine use in the USA), quite out of control. On the other hand, a move towards decriminalization or legalization is difficult because past propaganda has been so vehement that a change now apparently risks sending the wrong messages to young people. This dilemma means that there is no solution, including inertia, which is risk-free, nor is there one free of difficulties. It is thus relevant to think in terms of 'least bad' rather than 'best' when formulating a system to face these problems. The exploration of what this least bad solution might be begins with the examination of the prominent myths (such as 'the drug-free society', 'the evil pusher', 'the user as victim' and 'the young person as cultural dope') that hinder our reasoning. Secondly, by suggesting that, in a climate of increasing crime related to drugs, inability of prohibitions to control that use and escalating health risks attendant on use (including the AIDS problem), the central policy thrust must be harm reduction and damage minimization rather than illusory goals such as widespread abstinence. The paper concludes with a discussion of some relevant evidence on alternative options.

    Full Text Available This paper investigates the discourses and policies on narcotics in Republic of Korea from 1945 to 1960. Since the Liberation the narcotic problem was regarded as the vestige of Japanese imperialism. which was expected to be cleaned up. The image of narcotic crimes as the legacy of the colonial past was turned into as the result of the Red Army’s tactics to attack on the liberalist camp around the Korean war. The government of ROK represented the source of the illegal drugs as the Red army and the spy from North Korea. The anticommunist discourse about narcotics described the spies, who introduced the enormous amount of poppies into ROK and brought about the addicts, as the social evil. Through this discourse on poppies from North Korea, the government of ROK emphasized the immorality of the communists reinforcing the anticommunist regime, which was inevitable for the government of ROK to legitimize the division of Korea and the establishment of the government alone. This paper examines how the discourses and policies on narcotics in ROK was shaped and transformed from 1945 to 1960 focusing the relationship between the them and the political context such as anticommunism, Korean war, the division of Korea, and etc. This approach would be helpful to reveal the effect of the ROK’s own political situation to the public health system involving the management for drugs.

    Full Text Available ′The National health Policy 2002" of India and the "Roll Back Malaria" policy makers have set up an ambitious goal of reducing malaria mortality and morbidity by 25% by 2007, and by 50% by 2010. To achieve these goals, problems should be identified, available evidence analyzed and policy should be changed early. Infection with drug resistant malarial parasites has a tremendous impact on health (prolonged recurrent illness, increased hospital admissions and death, health system (higher cost of treatment and socioeconomics of the region. In view of the evidence of the economic burden of malaria, it has been suggested that second line treatment could be considered at 10% failure instead of 25%. Effective schizonticidal drugs will not only reduce morbidity and mortality but will also reduce transmission. Studies have shown that prevalence of viable (as tested by exflagellation test gametocytes is considerably more after the Chloroquine or Chloroquine + Sulphadoxine-Pyrimethamine treatment compared to Quinine. Unfortunately, the only gametocytocidal drug for Plasmodium falciparum, primaquine, is also loosing its efficacy. 45 mg Primaquine reduces gametocyte prevalence by 50% while a new drug, 75 mg bulaquine or 60 mg primaquine reduces it by 90%. Plasmodium vivax forms 60-70% of malaria cases in India. Relapses which occur in 10-20% of cases adds to the burden. Efficacy, as confirmed by Polymerase Chain Reaction-Single Strand Conformational Polymorphism (PCRSSCP to differentiate relapse and re-infection, of standard dose of primaquine (15 mg/day for 5 days, even 15 mg/day for 14 days for vivax malaria is reducing. Fourteen day treatment is also impractical as compliance is poor. Newer drugs, newer drug delivery systems are thus needed. Slow release formulations with blood levels maintained for one week may be useful. Rationale of giving primaquine in higher doses and different timing need to be considered.

    Treatment-resistant hypertension (TRH) is associated with particular clinical features, nonadherence, and suboptimal treatment. We assessed possible associations of antihypertensive drug classes, specific agents inside each class, and types of combinations, with the presence of non-TRH vs. TRH, and with controlled vs. uncontrolled TRH. Comparisons were done in 14 264 patients treated with three drugs (non-TRH: 2988; TRH: 11 276) and in 6974 treated with at least four drugs (controlled TRH: 1383; uncontrolled TRH: 5591). Associations were adjusted for age, sex, and previous cardiovascular event. In both groups of patients treated with three or with at least four drugs, aldosterone antagonists among drug classes [adjusted odds ratio (OR): 1.82 and 1.41, respectively], and ramipril (OR: 1.28 and 1.30), olmesartan (OR: 1.31 and 1.37), and amlodipine (OR: 1.11 and 1.41) inside each class were significantly associated with blood pressure control (non-TRH or controlled TRH). In patients treated with three drugs, non-TRH was also associated with the use of chlorthalidone (OR: 1.50) and bisoprolol (OR: 1.19), whereas in patients treated with at least four drugs, controlled TRH was significantly associated with the triple combination of a renin-angiotensin system blocker, a calcium channel blocker, and a diuretic (OR: 1.17). The use of aldosterone antagonists is associated with blood pressure control in patients treated with three or more drugs. Similar results are observed with specific agents inside each class, being ramipril, olmesartan, chlorthalidone, amlodipine, and bisoprolol those exhibiting significant results. An increased use of these drugs might probably reduce the burden of TRH.

    This paper proposes a novel hypnosis control method using Auditory Evoked Potential Index (aepEX) as a hypnosis index. In order to avoid side effects of an anesthetic drug, it is desirable to reduce the amount of an anesthetic drug during surgery. For this purpose many studies of hypnosis control systems have been done. Most of them use Bispectral Index (BIS), another hypnosis index, but it has problems of dependence on anesthetic drugs and nonsmooth change near some particular values. On the other hand, aepEX has an ability of clear distinction between patient consciousness and unconsciousness and independence of anesthetic drugs. The control method proposed in this paper consists of two elements: estimating the minimum effect-site concentration for maintaining appropriate hypnosis and adjusting infusion rate of an anesthetic drug, propofol, using model predictive control. The minimum effect-site concentration is estimated utilizing the property of aepEX pharmacodynamics. The infusion rate of propofol is adjusted so that effect-site concentration of propofol may be kept near and always above the minimum effect-site concentration. Simulation results of hypnosis control using the proposed method show that the minimum concentration can be estimated appropriately and that the proposed control method can maintain hypnosis adequately and reduce the total infusion amount of propofol.

    A novel solution-enhanced dispersion by supercritical CO{sub 2} (SEDS) was employed to prepare silk fibroin (SF) nanoparticles. The resulting SF nanoparticles exhibited a good spherical shape, a smooth surface, and a narrow particle size distribution with a mean particle diameter of about 50 nm. The results of X-ray powder diffraction, thermo gravimetry-differential scanning calorimetry, and Fourier transform infrared spectroscopy analysis of the SF nanoparticles before and after ethanol treatment indicated conformation transition of SF nanoparticles from random coil to {beta}-sheet form and thus water insolubility. The MTS assay also suggested that the SF nanoparticles after ethanol treatment imposed no toxicity. A non-steroidal anti-inflammatory drug, indomethacin (IDMC), was chosen as the model drug and was encapsulated in SF nanoparticles by the SEDS process. The resulting IDMC-SF nanoparticles, after ethanol treatment, possessed a theoretical average drug load of 20%, an actual drug load of 2.05%, and an encapsulation efficiency of 10.23%. In vitro IDMC release from the IDMC-SF nanoparticles after ethanol treatment showed a significantly sustained release over 2 days. These studies of SF nanoparticles indicated the suitability of the SF nanoparticles prepared by the SEDS process as a biocompatible carrier to deliver drugs and also the feasibility of using the SEDS process to reach the goal of co-precipitation of drug and SF as composite nanoparticles for controlled drug delivery.

    This study examines the effect of past tobacco control policies and projects the effect of future policies on smoking and snus use prevalence and associated premature mortality in Sweden. The established SimSmoke model was adapted with population, smoking rates and tobacco control policy data from Sweden. SimSmoke evaluates the effect of taxes, smoke-free air, mass media, marketing bans, warning labels, cessation treatment and youth access policies on smoking and snus prevalence and the number of deaths attributable to smoking and snus use by gender from 2010 to 2040. Sweden SimSmoke estimates that significant inroads to reducing smoking and snus prevalence and premature mortality can be achieved through tax increases, especially when combined with other policies. Smoking prevalence can be decreased by as much as 26% in the first few years, reaching a 37% reduction within 30 years. Without effective tobacco control policies, almost 54 500 lives will be lost in Sweden due to tobacco use by the year 2040. Besides presenting the benefits of a comprehensive tobacco control strategy, the model identifies gaps in surveillance and evaluation that can help better focus tobacco control policy in Sweden. © The Author 2013.

    The main target of tissue engineering is the preparation and application of adequate materials for the design and production of scaffolds, that possess properties promoting cell adhesion, proliferation and differentiation. The use of natural polysaccharides, such as chitosan, to prepare hydrogels for wound healing and controlled drug delivery is a research topic of wide and increasing interest. Areas covered: This review presents the latest results and challenges in the preparation of chitosan and chitosan-based scaffold/hydrogel for wound healing applications. A detailed overview of their behavior in terms of controlled drug delivery, divided by drug categories, and efficacy was provided and critically discussed. Expert opinion: The need to establish and exploit the advantages of natural biomaterials in combination with active compounds is playing a pivotal role in the regenerative medicine fields. The challenges posed by the many variables affecting tissue repair and regeneration need to be standardized and adhere to recognized guidelines to improve the quality of evidence in the wound healing process. Currently, different methodologies are followed to prepare innovative scaffold formulations and structures. Innovative technologies such as 3D printing or bio-electrospray are promising to create chitosan-based scaffolds with finely controlled structures with customizable shape porosity and thickness. Chitosan scaffolds could be designed in combination with a variety of polysaccharides or active compounds with selected and reproducible spacial distribution, providing active wound dressing with highly tunable controlled drug delivery.

    The legal background of the current pharmaceutical pricing and reimbursement (P&R) setting in the Czech Republic is based on Act 48/1997. Since 2008, the P&R process has been coordinated by the State Institute for Drug Control, which is the main stakeholder in the decision-making process; marketing authorization holders and insurance funds (IFs) also participate. To present a general overview of the current Czech health care system and its P&R principles. The study used publicly available sources concerning health care, mainly acts related to public health care and public health care insurance, public notices related to P&R setting, and statistical data. Regulation covers P&R. The official price represents the highest exfactory price, which cannot be exceeded. It is calculated as the mean of the three lowest prices in the European Union reference basket. Reimbursement is based on the lowest price per daily dose across the whole European Union. For reimbursement, products can be clustered into jumbo groups (mutually interchangeable), stated by law. In each group, reimbursement is set at the lowest price of any substance within the group. For highly innovative drugs a temporary reimbursement can be granted for a period of 3 years. During the administrative proceeding, efficacy, safety, cost-effectiveness, and budget impact are assessed. The cost-effectiveness principles are aligned with the guidelines of the National Institute for Health and Clinical Care Excellence, preferring cost-utility analyses. The willingness-to-pay threshold has been implicitly set at 3 times the gross domestic product per capita. Products exceeding this threshold are subject to further risk-sharing negotiations. Budget impact is becoming increasingly important mainly for IFs. The IFs have recently introduced their own methodology, which allows only products with a budget impact in the range of CZK16 to CZK48 million (CZK = Czech koruna; ∼€600,000 to €1.8 million) to enter the system

    Public agencies have discretion on the time domain, and politicians deploy numerous policy instruments to constrain it. Yet little is known about how administrative procedures that affect timing also affect the quality of agency decisions. We examine whether administrative deadlines shape decision timing and the observed quality of decisions. Using a unique and rich dataset of FDA drug approvals that allows us to examine decision timing and quality, we find that this administrative tool induces a piling of decisions before deadlines, and that these “just-before-deadline” approvals are linked with higher rates of postmarket safety problems (market withdrawals, severe safety warnings, safety alerts). Examination of data from FDA advisory committees suggests that the deadlines may impede quality by impairing late-stage deliberation and agency risk communication. Our results both support and challenge reigning theories about administrative procedures, suggesting they embody expected control-expertise trade-offs, but may also create unanticipated constituency losses.

  16. How state and federal policies as well as advances in genome science contribute to the high cost of cancer drugs.

    Science.gov (United States)

    Ramsey, Scott D

    2015-04-01

    During a time when cancer drug prices are increasing at an unprecedented rate, a debate has emerged as to whether these drugs continue to provide good value. In this article I argue that this debate is irrelevant because under today's highly distorted market, prices will not be set with value considerations in mind. As an alternative, I suggest considering the "value" of three policy changes—Medicare's "average sales price plus 6 percent" payment program, laws that require insurance coverage of all new cancer drugs, and the Affordable Care Act—that are fueling manufacturers' willingness to set higher prices. More important than these issues, however, is the revolution that is occurring in molecular biology and its impact on scientists' ability to detect changes in the cancer genome. The lowered cost of discovery is driving more competitors into the market, which under distorted pricing paradoxically encourages drug makers to charge ever higher prices for their products.

    2011-11-01

    Full Text Available In the last decade, a plethora of studies utilizing pharmacological, biochemical, and genetic approaches have shown that precise translational control is required for long-lasting synaptic plasticity and the formation of long-term memory. Moreover, more recent studies indicate that alterations in translational control are a common pathophysiological feature of human neurological disorders, including developmental disorders, neuropsychiatric disorders, and neurodegenerative diseases. Finally, translational control mechanisms are susceptible to modification by psychoactive drugs. Taken together, these findings point to a central role for translational control in the regulation of synaptic function and behavior.

    The aim is to extend understanding of the policy and practice discourses that inform the development of national tobacco control policy to protect children from secondhand smoke exposure (SHSE) in the home, particularly in a country with successful implementation of smoke-free public places legislation. The Scottish experience will contribute to the tobacco control community, particularly those countries at a similar level of tobacco control, as normalising discourses about protecting children from SHSE are becoming more widespread. Case study design using qualitative interviews and focus groups (FGs) with policy makers, health and childcare practitioners during which they were presented with the findings of the Reducing Families' Exposure to Secondhand Smoke (REFRESH) intervention and discussed the implications for their policy and practice priorities. Scotland, UK PARTICIPANTS: Qualitative interviews and FGs were conducted with 30 policy makers and practitioners who were purposively recruited. Participants accepted the harm of SHSE to children; however, action is limited by political expedience due to-the perception of a shift of the public health priority from smoking to alcohol, current financial constraints, more immediate child protection concerns and continuing unresolved ethical arguments. In a country, such as Scotland, with advanced tobacco control strategies, there continue to be challenges to policy and practice development in the more contentious arena of the home. Children's SHSE in their homes is unequivocally accepted as an important health priority, but it is not currently perceived to be a top public health priority in Scotland.

  19. Common errors of drug administration in infants: causes and avoidance.

    Science.gov (United States)

    Anderson, B J; Ellis, J F

    1999-01-01

    Drug administration errors are common in infants. Although the infant population has a high exposure to drugs, there are few data concerning pharmacokinetics or pharmacodynamics, or the influence of paediatric diseases on these processes. Children remain therapeutic orphans. Formulations are often suitable only for adults; in addition, the lack of maturation of drug elimination processes, alteration of body composition and influence of size render the calculation of drug doses complex in infants. The commonest drug administration error in infants is one of dose, and the commonest hospital site for this error is the intensive care unit. Drug errors are a consequence of system error, and preventive strategies are possible through system analysis. The goal of a zero drug error rate should be aggressively sought, with systems in place that aim to eliminate the effects of inevitable human error. This involves review of the entire system from drug manufacture to drug administration. The nuclear industry, telecommunications and air traffic control services all practise error reduction policies with zero error as a clear goal, not by finding fault in the individual, but by identifying faults in the system and building into that system mechanisms for picking up faults before they occur. Such policies could be adapted to medicine using interventions both specific (the production of formulations which are for children only and clearly labelled, regular audit by pharmacists, legible prescriptions, standardised dose tables) and general (paediatric drug trials, education programmes, nonpunitive error reporting) to reduce the number of errors made in giving medication to infants.

    It appears that the continuous efforts to add up of tobacco control policies in the context of a nationwide anti-tobacco mass media campaign that includes the Quitline number is the most effective approach to maintaining the upward trend in smoking cessation intentions. Based on the Korean experience, Quitline data may be useful for measuring the impact of tobacco control policies and campaigns in Asian Pacific countries.

    Due to the significantly high levels of comorbid substance use and mental health diagnosis among urban poor populations, examining the intersection of drug policy and place requires a consideration of the role of housing in drug user mental health. In San Francisco, geographic boundedness and progressive health and housing polices have coalesced to make single room occupancy hotels (SROs) a key urban built environment used to house poor populations with co-occurring drug use and mental health issues. Unstably housed women who use illicit drugs have high rates of lifetime and current trauma, which manifests in disproportionately high rates of post-traumatic stress disorder (PTSD), anxiety, and depression when compared to stably housed women. We report data from a qualitative interview study (n=30) and four years of ethnography conducted with housing policy makers and unstably housed women who use drugs and live in SROs. Women in the study lived in a range of SRO built environments, from publicly funded, newly built SROs to privately owned, dilapidated buildings, which presented a rich opportunity for ethnographic comparison. Applying Rhodes et al.'s framework of socio-structural vulnerability, we explore how SROs can operate as "mental health risk environments" in which macro-structural factors (housing policies shaping the built environment) interact with meso-level factors (social relations within SROs) and micro-level, behavioral coping strategies to impact women's mental health. The degree to which SRO built environments were "trauma-sensitive" at the macro level significantly influenced women's mental health at meso- and micro-levels. Women who were living in SROs which exacerbated fear and anxiety attempted, with limited success, to deploy strategies on the meso- and micro-level to manage their mental health symptoms. Study findings underscore the importance of housing polices which consider substance use in the context of current and cumulative trauma

  4. Harmonisation of European Migration Policies: The Failure of Immigration Control Policies in the Seventh and Eighth Decades of the 20th Century

    Directory of Open Access Journals (Sweden)

    Milan Mesić

    2003-12-01

    Full Text Available Until the middle of the 1970s, the migration policies of developed European countries were based on the assumption that controlling immigration was possible. Due to various reasons discussed in this article, such policies proved unsuccessful. The result was an increase in the total number of foreigners and a change in the composition of immigrant communities, i.e. the proportion of supported family members increased. During the 1980s there was increasing convergence in the migration policies of European immigration countries and traditional overseas emigration countries. Policies were more and more oriented towards preventing illegal migration flows, on regulating refugee flows and on balancing labour migration with family migration. The turning-point in the direction of “harmonising” West European migration policies was marked by the Schengen agreement (1985 on gradual elimination of border controls between the signing parties (France, Germany and the Benelux countries. Fear in the face of a possible invasion of Eastern Europeans after the collapse of socialism in 1989 was a further strong stimulus towards the harmonisation of migration policies in the developing EU. As opposed to migration control, the integration of immigrants has remained so far the prerogative of nation-states. The text further presents an overview of migration policy reforms in individual member states of the EU and of multilateral actions. The post-1989 migration regime in Europe has four major traits: 1 an extension of the agenda; 2 an accent on joint actions; 3 defensiveness; 4 confusion and an overload of issues. While on the one hand the EU continues to seek ways of protecting itself from undesired external migration, on the other hand the process of regional integration continues to “erase” its internal borders.

    The U.S. Army Research Laboratory (ARL) Multimodal Signatures Database (MMSDB) consists of a number of colocated relational databases representing a collection of data from various sensors. Role-based access to this data is granted to external organizations such as DoD contractors and other government agencies through a client Web portal. In the current MMSDB system, access control is only at the database and firewall level. In order to offer finer grained security, changes to existing user profile schemas and authentication mechanisms are usually needed. In this paper, we describe a software middleware architecture and implementation that allows fine-grained access control to the MMSDB at a dataset, table, and row level. Result sets from MMSDB queries issued in the client portal are filtered with the use of a policy enforcement proxy, with minimal changes to the existing client software and database. Before resulting data is returned to the client, policies are evaluated to determine if the user or role is authorized to access the data. Policies can be authored to filter data at the row, table or column level of a result set. The system uses various technologies developed in the International Technology Alliance in Network and Information Science (ITA) for policy-controlled information sharing and dissemination1. Use of the Policy Management Library provides a mechanism for the management and evaluation of policies to support finer grained access to the data in the MMSDB system. The GaianDB is a policy-enabled, federated database that acts as a proxy between the client application and the MMSDB system.

  6. Heightened vulnerability to MDR-TB epidemics after controlling drug-susceptible TB.

    Full Text Available Prior infection with one strain TB has been linked with diminished likelihood of re-infection by a new strain. This paper attempts to determine the role of declining prevalence of drug-susceptible TB in enabling future epidemics of MDR-TB.A computer simulation of MDR-TB epidemics was developed using an agent-based model platform programmed in NetLogo (See http://mdr.tbtools.org/. Eighty-one scenarios were created, varying levels of treatment quality, diagnostic accuracy, microbial fitness cost, and the degree of immunogenicity elicited by drug-susceptible TB. Outcome measures were the number of independent MDR-TB cases per trial and the proportion of trials resulting in MDR-TB epidemics for a 500 year period after drug therapy for TB is introduced.MDR-TB epidemics propagated more extensively after TB prevalence had fallen. At a case detection rate of 75%, improving therapeutic compliance from 50% to 75% can reduce the probability of an epidemic from 45% to 15%. Paradoxically, improving the case-detection rate from 50% to 75% when compliance with DOT is constant at 75% increases the probability of MDR-TB epidemics from 3% to 45%.The ability of MDR-TB to spread depends on the prevalence of drug-susceptible TB. Immunologic protection conferred by exposure to drug-susceptible TB can be a crucial factor that prevents MDR-TB epidemics when TB treatment is poor. Any single population that successfully reduces its burden of drug-susceptible TB will have reduced herd immunity to externally or internally introduced strains of MDR-TB and can experience heightened vulnerability to an epidemic. Since countries with good TB control may be more vulnerable, their self interest dictates greater promotion of case detection and DOTS implementation in countries with poor control to control their risk of MDR-TB.

    It is uncertain whether tobacco control policies have contributed to a narrowing or widening of socioeconomic inequalities in smoking in European countries during the past two decades. This paper aims to investigate the impact of price and non-price related population-wide tobacco control policies on smoking by socioeconomic group in nine European countries between 1990 and 2007. Individual-level education, occupation and smoking status were obtained from nationally representative surveys. Country-level price-related tobacco control policies were measured by the relative price of cheapest cigarettes and of cigarettes in the most popular price category. Country-level non-price policies were measured by a summary score covering four policy domains: smoking bans or restrictions in public places and workplaces, bans on advertising and promotion, health warning labels, and cessation services. The associations between policies and smoking were explored using logistic regressions, stratified by education and occupation, and adjusted for age, Gross Domestic Product, period and country fixed effects. The price of popular cigarettes and non-price policies were negatively associated with smoking among men. The price of the cheapest cigarettes was negatively associated with smoking among women. While these favorable effects were generally in the same direction for all socioeconomic groups, they were larger and statistically significant in lower socioeconomic groups only. Tobacco control policies as implemented in nine European countries, have probably helped to reduce the prevalence of smoking in the total population, particularly in lower socioeconomic groups. Widening inequalities in smoking may be explained by other factors. Policies with larger effects on lower socioeconomic groups are needed to reverse this trend. Socioeconomic inequalities in smoking widened between the 1990s and the 2000s in Europe. During the same period, there were intensified tobacco control policies

  10. Production and Investigation of Controlled Drug Release Properties of Tamoxifen Loaded Alginate-Gum Arabic Microbeads

    Rukiye Yavaşer

    2016-08-01

    Full Text Available The entrapment of tamoxifen onto alginate-gum arabic beads and the production of controlled drug release was investigated in this study. The polymeric system that would provide the controlled release of tamoxifen was formed using alginate and gum arabic. In the first phase of the study, the optimization of the alginate-gum arabic beads production was conducted; then the study continued with drug entrapment experiments. Tamoxifen entrapment yield was found to be approximately 90% of initial tamoxifen concentration. In vitro drug release experiments were performed in simulated gastric juice and intestinal fluid where the tamoxifen release was 20% and 53% of the initial drug present, respectively. As a result of this study, it is expected that a valuable contribution to the field of controlled drug release system production is realized.

  11. Off-Policy Actor-Critic Structure for Optimal Control of Unknown Systems With Disturbances.

    2016-05-01

    An optimal control method is developed for unknown continuous-time systems with unknown disturbances in this paper. The integral reinforcement learning (IRL) algorithm is presented to obtain the iterative control. Off-policy learning is used to allow the dynamics to be completely unknown. Neural networks are used to construct critic and action networks. It is shown that if there are unknown disturbances, off-policy IRL may not converge or may be biased. For reducing the influence of unknown disturbances, a disturbances compensation controller is added. It is proven that the weight errors are uniformly ultimately bounded based on Lyapunov techniques. Convergence of the Hamiltonian function is also proven. The simulation study demonstrates the effectiveness of the proposed optimal control method for unknown systems with disturbances.

The nanocomposite material coated with a membrane was biocompatible and integrated both specific tumor targeting and responsiveness to stimulation, which improved transmission efficacy and controlled drug release. Mesoporous silica nanoparticles (MSNs, which are known for their biocompatibility and high drug-loading capacity, were selected as a model drug container and carrier. The membrane was established by the polyelectrolyte composite method from chitosan (CS which was sensitive to the acidic tumor microenvironment, folic acid-modified CS which recognizes the folate receptor expressed on the tumor cell surface, and a CD44 receptor-targeted polysaccharide hyaluronic acid. We characterized the structure of the nanocomposite as well as the drug release behavior under the control of the pH-sensitive membrane switch and evaluated the antitumor efficacy of the system in vitro. Our results provide a basis for the design and fabrication of novel membrane-controlled nanoparticles with improved tumor-targeting therapy.

    The benefits of using antiparasitic drugs in farm animals are unquestionable. However, despite anthelmintic use as the predominant control strategy, extreme parasite infection cases are appearing in sheep and goat production; these impact productivity and have show mortality rates reaching pre-drug use levels. This was a predictable situation resulting from the loss of efficacy by all available products, particularly when some products were used as the sole intervention. The concepts of agroecology and holistic agriculture, which advocate the use of integrated management strategies, such as target selected treatment, herbal medicine, and the application of other parasite control alternatives, are not completely new, but are undergoing a resurgence because of their more sustainable appeal. The objective of this review article is to examine the problem of parasite control in the face of parasite drug resistance and to outline some strategies that may be used in parasite control programmes. Before they are accepted and recommended by the WAAVP, agroecological methods such as those listed above and described in detail herein should be validated based on scientific evidence of their efficacy for parasite control and should be tested for both host and environmental safety.

  15. Acidification policy - control of acidifying emissions in Germany

    International Nuclear Information System (INIS)

    Schaerer, B.

    1992-01-01

    Since the mid-eighties total annual acidifying emissions have started to decline in West Germany. There was considerable impact on this positive trend in air pollution by the control of SO 2 and NO x emissions from large boilers, which were reduced by more than 80%. Corresponding control programmes have been established for other groups of sources as well as other pollutants and - with unification - for East Germany. The driving force behind this development was and still is first of all the legal principle of anticipatory action or precaution which means in practical terms 'emission minimization'. This cornerstone of German clean air legislation is the most powerful components of Germany's 'acidification policy', as it requires policy-makers to draw up new or review existing regulations for emission reduction based on requirements according to the state of the art and forces operators to apply the most modern ways and means of operation. This paper describes the system used in Germany to deal with air pollution, the emission minimization strategy, and the actions against acidifying emissions based thereon. In addition, an outlook on what might be necessary to cope with the challenges of a sustainable development concerning acidification is given. 1 ref., 1 fig., 2 tabs

    Large-scale international events such as World Expos and Olympic Games have the potential to strengthen smoke-free norms globally. The Shanghai 2010 World Expo was one of the first large-scale events to implement and evaluate the adoption of strict tobacco control policies. To evaluate implementation of tobacco control policies at the 2010 World Expo in Shanghai, China. This mixed methods evaluation was conducted from July to October 2010. Observations were conducted in all 155 pavilions and outdoor queuing areas, all 45 souvenir shops, a random sample of restaurants (51 of 119) and selected outdoor non-smoking areas in all sections of the Expo. In addition, intercept surveys were completed with 3022 visitors over a 4-month period. All pavilions and souvenir shops were smoke-free. Restaurants were smoke-free, with only 0.1% of customers observed smoking. Smoking was more common in outdoor non-smoking areas, but still relatively rare overall with only 4.5% of visitors observed smoking. Tobacco products were not sold or marketed in any public settings except for three pavilions that had special exemptions from the policy. Overall, 80.3% of visitors were aware of the smoke-free policy at the World Expo, 92.5% of visitors supported the policy and 97.1% of visitors were satisfied with the smoke-free environment. Tobacco control policies at the World Expo sites were generally well-enforced and accepted although compliance was not 100%, particularly in outdoor non-smoking areas.

    The aim of this work was to evaluate the potentiality to control the drug release of a new architecture of microparticles organized at the nanoscopic scale by assembling polymeric nanocapsules at the surface of drug-loaded xerogels. Xerogel was prepared by sol-gel method using sodium diclofenac, as hydrophilic drug model, and coated by spray-drying. After coating, the surface areas decreased from 82 to 28 m(2)/g, the encapsulation efficiency was 71% and SEM analysis showed irregular microparticles coated by the nanocapsules. Formulation showed satisfactory gastro-resistance presenting drug release lower than 3% (60 min) in acid medium. In water, the pure drug dissolved 92% after 5 min, uncoated drug-loaded xerogel released 60% and nanocapsule coated drug-loaded xerogel 36%. After 60 min, uncoated drug-loaded xerogel released 82% and nanocapsule coated drug-loaded xerogel 62%. In conclusion, the new system was able to control the release of the hydrophilic drug model.

    We examined the effect of tobacco control policies in Mexico on smoking prevalence and smoking-related deaths using the Mexico SimSmoke model. The model is based on the previously developed SimSmoke simulation model of tobacco control policy, and uses population size, smoking rates and tobacco control policy data for Mexico. It assesses, individually, and in combination, the effect of six tobacco control policies on smoking prevalence and smoking-related deaths. Policies included: cigarette excise taxes, smoke-free laws, anti-smoking public education campaigns, marketing restrictions, access to tobacco cessation treatments and enforcement against tobacco sales youth. The model estimates that, if Mexico were to adopt strong tobacco control policies compared to current policy levels, smoking prevalence could be reduced by 30% in the next decade and by 50% by 2053; an additional 470,000 smoking-related premature deaths could be averted over the next 40 years. The greatest impact on smoking and smoking-related deaths would be achieved by raising excise taxes on cigarettes from 55% to at least 70% of the retail price, followed by strong youth access enforcement and access to cessation treatments. Implementing tobacco control policies in Mexico could reduce smoking prevalence by 50%, and prevent 470,000 smoking-related deaths by 2053.

    To assess the impact of tobacco control policies relating to youth access, clean indoor air and tobacco advertising at point-of-sale and outdoors, in addition to cigarette price and per capita tobacco control spending, on adolescent smoking prevalence. Repeated cross-sectional surveys. Logistic regression analyses examined association between policies and smoking prevalence. Australia, 1990-2005. A nationally representative sample of secondary students (aged 12-17 years) participating in a triennial survey (sample size per survey range: 20 560 to 27 480). Students' report of past-month smoking. In each jurisdiction, extent of implementation of the three policies for the year of the survey was determined. For each survey year, national per capita tobacco control spending was determined and jurisdiction-specific 12-month change in cigarette price obtained. Extent of implementation of the three policy areas varied between states and over the survey years. Multivariate analyses that adjusted for demographic factors, year and all tobacco control variables showed that 12-month cigarette price increases [odds ratio (OR): 0.98, 95% confidence interval (CI): 0.97-0.99], greater per capita tobacco control spending (OR: 0.99, 95% CI: 0.98-0.99) and stronger implementation of clean indoor air policies (OR: 0.93, 95% CI: 0.92-0.94) were associated with reduced smoking prevalence. Adult-directed, population-based tobacco control policies such as clean indoor air laws and increased prices of cigarettes, implemented as part of a well-funded comprehensive tobacco control programme are associated with lower adolescent smoking. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

  1. Changing an automated drug inventory control system to a data base design.

    Bradish, R A

    1982-09-01

    A pharmacy department's change from indexed sequential access files to a data base management system (DBMS) for purposes of automated inventory control is described. The DBMS has three main functional areas: (1) inventory ordering and accountability, (2) charging of interdepartmental and intradepartmental orders, and (3) data manipulation with report design for management control. There are seven files directly related to the inventory ordering and accountability area. Each record can be accessed directly or through another file. Information on the quantity of a drug on hand, drug(s) supplied by a specific vendor, status of a purchase order, or calculation of an estimated order quantity can be retrieved quickly. In the drug master file, two records contain a reorder point and safety-stock level that are determined by searching the entries in the order history file and vendor master file. The intradepartmental and interdepartmental orders section contains five files assigned to record and store information on drug distribution. All items removed from the stockroom and distributed are recorded, and reports can be generated for itemized bills, total cost by area, and as formatted files for the accounts payable department. The design, development, and implementation of the DBMS took approximately a year using a part-time pharmacist and minimal outside help, while the previous system required constant expensive help of a programmer/analyst. The DBMS has given the pharmacy department a flexible inventory management system with increased drug control, decreased operating expenses, increased use of department personnel, and the ability to develop and enhance other systems.

  3. New indicators of illegal drug use to compare drug user populations for policy evaluation

    Directory of Open Access Journals (Sweden)

    Francesco Fabi

    2013-11-01

    Full Text Available Background: New trends in drug consumption show a trend towards higher poly-use. Epidemiological indicators presently used are mostly based on the prevalence of users of the “main” substances and the ranking of harm caused by drug use is based on a single substance analysis.Methods: In this paper new indicators are proposed; the approach consider the segmentation of the population with respect to the frequency of use in the last 30 days and the harm score of the various substances used by a poly-user. Scoring is based on single substance score table reported in recent papers and principal component analysis is applied to reduce dimensionality. Any user ischaracterized by the two new scores: frequency of use score and poly-use score.Results: The method is applied to the drug user populations interviewed in Communities and Low Threshold Services within the Problem Drug Use 2012 survey in four different European countries. The comparison of the poly-use score cumulative distributions gives insight about behavioural trends of drug use and also evaluate the efficacy of the intervention services. Furthermore, the application of this method to School Population Survey 2011 data allows a definition of the expected behaviour of the poly-drug score for the General Population Survey to be representative.Conclusions: In general, the method is simply and intuitive, and could be applied to surveys containing questions about drug use. A possible limitations could be that the median is chosen for calculating the frequency of use score in questionnaires containing the frequency of drug use in classes.

  5. Generating news media interest in tobacco control; challenges in an advanced policy environment.

    MacKenzie, Ross; Chapman, Simon

    2012-08-01

    To determine the efficacy of using media releases for tobacco control advocacy in Australia's advanced policy environment. Between February and August 2010, news releases that summarised either newly published but unpublicized research findings, or local developments in tobacco control, were sent to NSW media outlets. Reports arising from the releases were tracked using commercial services Media Monitors and Factiva, as well as Google and Google News. Other tobacco control related news items during the same period were also tracked and recorded. Twenty-one news releases generated 93 news items across all news media, with a quarter of these related to a story of porcine haemoglobin in cigarette filters. By comparison, 'live' policy issues (especially plain packaging and a significant tobacco tax increase) covered in this period attracted 1,033 news stories in the Australian media. Press releases describing recently published, but underpublicized research were issued in weeks where no major competing tobacco control news occurred. Results of this project indicate that in environments with advanced tobacco policy, media opportunities related to tobacco control advocacy are limited, as many objectives have been achieved. The media can still play a key advocacy role in such environments, and advocates need to be particularly vigilant for opportunities that do arise. The paper also highlights the increasingly important role of internet-based media, including opportunities presented by social media for tobacco control.

    Parents play an important role in determining the risk of children's drug use. The aim of this study was to analyse how certain family-related variables (permissiveness toward drug use, and parental control and affect) were linked to the use of alcohol, tobacco and cannabis, based on young people's self-report of such variables. The sample was composed of 1,428 school children (51.8% males) aged between 11 and 19 from Mallorca (Spain). We found that the young people who perceived their parents as permissive and those who perceived less maternal control and higher levels of both paternal and maternal affect were more likely to use alcohol, tobacco and cannabis. Sex differences were found within this pattern. Variables of maternal affect and control were not influential among males, whereas the general pattern was maintained among females. This study highlights the importance of perceived permissiveness and the need of considering parent's and children's gender when providing control and affect, as fathers will influence male children whereas mothers will influence female children.

    Nanomedicine has been growing exponentially due to its enhanced drug targeting and reduced drug toxicity. It uses the interactions where nanotechnological components and biological systems communicate with each other to facilitate the delivery performance. At this scale, the physiochemical properties of delivery systems strongly affect their capacities. Among current delivery systems, DNA nanotechnology shows many advantages because of its unprecedented engineering abilities. Through molecular recognition, DNA nanotechnology can be used to construct a variety of nanostructures with precisely controllable size, shape, and surface chemistry, which can be appreciated in the delivery process. In this review, different approaches that are currently used for the construction of DNA nanostructures are reported. Further, the utilization of these DNA nanostructures with the well-defined parameters for the precise control in drug delivery and gene therapy is discussed. © 2016 WILEY-VCH Verlag GmbH & Co.

    Natural silk protein nanoparticles are a promising biomaterial for drug delivery due to their pleiotropic properties, including biocompatibility, high bioavailability, and biodegradability. Chinese oak tasar Antheraea pernyi silk fibroin (ApF) nanoparticles are easily obtained using cations as reagents under mild conditions. The mild conditions are potentially advantageous for the encapsulation of sensitive drugs and therapeutic molecules. In the present study, silk fibroin protein nanoparticles are loaded with differently-charged small-molecule drugs, such as doxorubicin hydrochloride, ibuprofen, and ibuprofen-Na, by simple absorption based on electrostatic interactions. The structure, morphology and biocompatibility of the silk nanoparticles in vitro are investigated. In vitro release of the drugs from the nanoparticles depends on charge-charge interactions between the drugs and the nanoparticles. The release behavior of the compounds from the nanoparticles demonstrates that positively-charged molecules are released in a more prolonged or sustained manner. Cell viability studies with L929 demonstrated that the ApF nanoparticles significantly promoted cell growth. The results suggest that Chinese oak tasar Antheraea pernyi silk fibroin nanoparticles can be used as an alternative matrix for drug carrying and controlled release in diverse biomedical applications.

    Full Text Available While a typical way for diabetes therapy is discrete insulin infusion based on long-time interval measurement, in this paper, we design a closed-loop control system for continuous drug infusion to improve the traditional discrete methods and make diabetes therapy automatic in practice. By exploring the accumulative function of drug to insulin, a continuous injection model is proposed. Based on this model, proportional-integral-derivative (PID and fuzzy logic controllers are designed to tackle a control problem of the resulting highly nonlinear plant. Even with serious disturbance of glucose, such as nutrition absorption at meal time, the proposed scheme can perform well in simulation experiments.

    Malaria healthcare policy change in Kenya aimed at improving the control of malaria but faced a number of challenges in implementation related to marketing of the drugs. This research investigated the effect of the change of the national malaria policy on drug sales and strategic marketing responses of antimalarial pharmaceutical companies in Kenya. A descriptive cross-sectional design was employed to describe the existing state of antimalarials market in Kenya after the change of the malaria healthcare policy. Policy change did result in an increase in the sales of Coartem®. Novartis Pharma recorded a 97% growth in sales of Coartem® between 2003 and 2004. However, this increase was not experienced by all the companies. Further, SPs (which had been replaced as first-line therapy for malaria) registered good sales. In most cases, these sales were higher than the sales of Coartem®. Generally, the sales contribution of SPs and generic antimalarial medicines exceeded that of Coartem® for most distributors. The most common change made to marketing strategies by distributors (62.5%) was to increase imports of antimalarials. A total of 40% of the manufacturers preferred to increase their budgetary allocation for marketing activities. In view of the fact that continued sale of SP drugs and limited availability of AL poses the risk of increasing the incidence of malaria in Kenya, it is therefore, recommended that pharmacy surveillance systems be strengthened to ensure drugs that have been rendered non-viable or that prescription-only medicines are not sold contrary to the national guidelines.

    Full Text Available The aim of the present study was to assess the risk of having a traffic accident after using alcohol, single drugs, or a combination, and to determine the concentrations at which this risk is significantly increased.A population-based case-control study was carried out, collecting whole blood samples of both cases and controls, in which a number of drugs were detected. The risk of having an accident when under the influence of drugs was estimated using logistic regression adjusting for gender, age and time period of accident (cases/sampling (controls. The main outcome measures were odds ratio (OR for accident risk associated with single and multiple drug use. In total, 337 cases (negative: 176; positive: 161 and 2726 controls (negative: 2425; positive: 301 were included in the study.Main findings were that 1 alcohol in general (all the concentrations together caused an elevated crash risk; 2 cannabis in general also caused an increase in accident risk; at a cut-off of 2 ng/mL THC the risk of having an accident was four times the risk associated with the lowest THC concentrations; 3 when ranking the adjusted OR from lowest to highest risk, alcohol alone or in combination with other drugs was related to a very elevated crash risk, with the highest risk for stimulants combined with sedatives.The study demonstrated a concentration-dependent crash risk for THC positive drivers. Alcohol and alcohol-drug combinations are by far the most prevalent substances in drivers and subsequently pose the largest risk in traffic, both in terms of risk and scope.

  19. Economic policy instruments for the control of air pollution in Poland

    Bates, R.W.

    1993-01-01

    The World Bank is analyzing the role of economic policy instruments for the control of air pollution in Poland, in cooperation with Polish and international experts. The first stage, covering Poland as a whole, was recently completed, jointly financed with the U.S. E.P.A. and the Government of the Netherlands. The second stage, now under way, will extend the analysis into a specific regional framework. Stage 2 is financed by the World Bank, the Polish Government, and the U.K. Environment Know-How Fund. Air Pollution in Poland is overwhelmingly caused by energy production and uses, due to the fact that the Polish economy depends heavily on coal and lignite. At present, vehicles contribute less to total emissions than do coal burning and industrial processes, although they account for 25-35% of nitrogen oxides, carbon monoxide, hydrocarbons and lead; and the concentrated in areas of high population density. The paper shows how economic, technical and meteorological modelling can be used, to reach conclusions about cost-effective strategies for the control of emissions and the improvement of ambient air quality. A simulation approach is presented, to compare alternative policy instruments, in terms of their impact on emissions and control costs for Poland as a whole. The main instruments considered are open-quotes command-and-controlclose quotes regimes (C ampersand C) and economic incentives, namely fuel taxes, emissions taxes and emissions trading. Next, the paper describes how the analysis is being extended, to link emissions with ambient air quality, using air dispersion modelling, based on a case study for Krakow. Finally, some conclusions are drawn on the importance of sound economic policies for air quality management, the costs of alternative standards, C ampersand C approaches versus economic incentives, a practical strategy to develop an effective role for emissions taxes and trading, and the regional differentiation of policy instruments

    2016-07-01

    In the 1970s, Turkey ceased to be a significant producer state of illicit drugs, but it continued to serve as a key route for the trade of drugs between East and West. Over the past decade, however, authorities identified two concerns beyond its continued transit state status. These reported problems entail both new modes of production and a rising incidence of drug abuse within the nation-state - particularly among its youth. Amid these developments, new law enforcement institutions emerged and acquired European sponsorship, leading to the establishment of TUBİM (the Turkish Monitoring Center for Drugs and Drug Addiction). Coordinating with and reporting to the European Union agency EMCDDA (the European Monitoring Center for Drugs and Drug Addiction), TUBİM's primary assigned duties entail the collection and analysis of data on drug abuse, trafficking, and prevention, the geographic identification of sites of concern (e.g. consumption, drug-related crimes, and peoples undergoing treatment), and the production of annual national reports. In this article, we examine the geopolitical origins of TUBİM as Turkey's central apparatus for confronting drug problems and its role as a vehicle for policy development, interpretation, and enforcement. In doing so, we emphasize the political and spatial dimensions inherent to the country's institutional and policy-driven approaches to contend with drug-related problems, and we assess how this line of attack reveals particular ambiguities in mission when evaluated from scales at world regional, national, and local levels. In sum, we assess how Turkey's new institutional and legislative landscapes condition the state's engagements with drug use, matters of user's health, and policy implementation at local scales and amid ongoing political developments.

    2015-01-01

    The Family Smoking Prevention and Tobacco Control Act (FSPTCA) give the U.S. Food and Drug Administration (FDA) unprecedented power to regulate tobacco products. One of the most significant provisions of the law allows state and local governments to adopt and enforce tobacco control legislation restricting the time, place, and manner (but not the content) of tobacco advertising. However, there is still reluctance among states and localities for mass adoption of laws due to challenges associated with legal feasibility and lack of U.S.-based evidence in effectiveness. The Center for Public Health Systems Science conducted interviews with key tobacco control contacts in 48 states at two time points (2012 and 2014) since the passage of the FSPTCA to assess the influence of the law on point-of-sale policy development in their state tobacco programs. Logistic regression results show that point-of-sale policy importance is growing post-FSPTCA, and that key influencers of this importance are states' tobacco control histories and environments, including that related to excise taxes and smoke free air policies. The adoption of smokefree and tax policies has become commonplace across the U.S., and the quality and extent of these laws and prevailing political will increasingly impact the ability of states to work in emerging tobacco control policy areas including those directed at the point of sale.

    In this work, dextran, a polysaccharide with excellent biocompatibility, is applied as the "gatekeeper" to fabricate the pH-sensitive dextran/mesoporous silica nanoparticles (MSNs) based drug delivery systems for controlled intracellular drug release. Dextran encapsulating on the surface of MSNs is oxidized by NaIO 4 to obtain three kinds of dextran dialdehydes (PADs), which are then coupled with MSNs via pH-sensitive hydrazone bond to fabricate three kinds of drug carriers. At pH 7.4, PADs block the pores to prevent premature release of anti-cancer drug doxorubicin hydrochloride (DOX). However, in the weakly acidic intracellular environment (pH∼5.5) the hydrazone can be ruptured; and the drug can be released from the carriers. The drug loading capacity, entrapment efficiency and release rates of the drug carriers can be adjusted by the amount of NaIO 4 applied in the oxidation reaction. And from which DOX@MSN-NH-N=C-PAD 10 is chosen as the most satisfactory one for the further in vitro cytotoxicity studies and cellular uptake studies. The results demonstrate that DOX@MSN-NH-N=C-PAD 10 with an excellent pH-sensitivity can enter HeLa cells to release DOX intracellular due to the weakly acidic pH intracellular and kill the cells. In our opinion, the ingenious pH-sensitive drug delivery systems have application potentials for cancer therapy. Copyright © 2017 Elsevier B.V. All rights reserved.

    2014-01-01

    This study addresses the occurrences and natural fates of chemotherapeutics and controlled drugs when found together in hospital effluents and surface waters. The results revealed the presence of 11 out of 16 drugs in hospital effluents, and the maximum detected concentrations were at the μg L −1 level in the hospital effluents and the ng L −1 level in surface waters. The highest concentrations corresponded to meperidine, morphine, 5-fluorouracil and cyclophosphamide. The sunlight photolysis of the target compounds was investigated, and the results indicated that morphine and codeine can be significantly attenuated, with half-lives of 0.27 and 2.5 h, respectively, in natural waters. Photolysis can lower the detected environmental concentrations, also lowering the estimated environmental risks of the target drugs to human health. Nevertheless, 5-fluorouracil and codeine were found to have a high risk quotient (RQ), demonstrating the high risks of directly releasing hospital wastewater into the environment. - Highlights: • High occurrence of chemotherapeutics and controlled substances in aqueous systems. • Photolysis lowers the detected concentrations of morphine and codeine. • 5-fluorouracil and codeine in hospital effluents have high risk quotients. - Chemotherapeutics and controlled drugs occur at significant levels in hospital effluents and surface waters. Natural sunlight photolysis reduces their environmental occurrence

    Seetoh, Theresa; Liverani, Marco; Coker, Richard

    2012-01-01

    This article explores differing understandings of 'risk' in relation to pandemic influenza policy and control. After a preliminary overview of methodological and practical problems in risk analysis, ways in which risk was framed and managed in three historical cases were examined. The interdependence between scientific empiricism and political decision-making led to the mismanagement of the 1976 swine influenza scare in the USA. The 2004 H5N1 avian influenza outbreak in Thailand, on the other hand, was undermined by questions of national economic interest and concerns over global health security. Finally, the recent global emergency of pandemic influenza H1N1 in 2009 demonstrated the difficulties of risk management under a context of pre-established perceptions about the characteristics and inevitability of a pandemic. Following the analysis of these cases, a conceptual framework is presented to illustrate ways in which changing relationships between risk assessment, risk perception and risk management can result in differing policy strategies.

    2015-01-01

    In this work, porous octyl-dextran microspheres with excellent properties were prepared by two steps. Firstly, dextran microspheres were synthesized by reversed-phase suspension polymerization. Secondly, octyl-dextran microspheres were prepared by the reaction between dextran microspheres and ethylhexyl glycidyl ether and freezing-drying method. Porous structure of microspheres was formed through the interaction between octyl groups and organic solvents. The structure, morphology, dry density, porosity and equilibrium water content of porous octyl-dextran microspheres were systematically investigated. The octyl content affected the properties of microspheres. The results showed that the dry density of microspheres decreased from 2.35 to 1.21 g/ml, porosity increased from 80.68 to 95.05% with the octyl content increasing from 0.49 to 2.28 mmol/g. Meanwhile, the equilibrium water content presented a peak value (90.18%) when the octyl content was 2.25 mmol/g. Octyl-dextran microspheres showed high capacity. Naturally drug carriers play an important role in drug-delivery systems for their biodegradability, wide raw materials sources and nontoxicity. Doxorubicin (DOX) was used as a drug model to examine the drug-loading capacity of porous octyl-dextran microspheres. The drug-loading efficiency increased with the increase in microspheres/drug ratio, while the encapsulation efficiency decreased. When microspheres/drug mass ratio was 4/1, the drug-loading efficiency and encapsulation efficiency were 10.20 and 51.00%, respectively. The release rate of DOX increased as drug content and porosity increased. In conclusion, porous octyl-dextran microspheres were synthesized successfully and have the potential to serve as an effective delivery system in drug controlled release.

    Joshua Chou

    Full Text Available Simvastatin have been shown to induce bone formation and there is currently a urgent need to develop an appropriate delivery system to sustain the release of the drug to increase therapeutic efficacy whilst reducing side effects. In this study, a novel drug delivery system for simvastatin by means of hydrothermally converting marine exoskeletons to biocompatible beta-tricalcium phosphate was investigated. Furthermore, the release of simvastatin was controlled by the addition of an outer apatite coating layer. The samples were characterized by x-ray diffraction analysis, fourier transform infrared spectroscopy, scanning electron microscopy and mass spectroscopy confirming the conversion process. The in-vitro dissolution of key chemical compositional elements and the release of simvastatin were measured in simulated body fluid solution showing controlled release with reduction of approximately 25% compared with un-coated samples. This study shows the potential applications of marine structures as a drug delivery system for simvastatin.

    2013-01-01

    Improper dependencies slant policy over a drug's life span, biasing the development of new drugs, the testing and marketing approval for new drugs, and the monitoring of patient safety after drugs are marketed. This article examines five ways in which the public improperly depends on pharmaceutical firms that compromise the integrity of pharmaceutical policy. Today the public relies on pharmaceutical firms: (1) to set priorities on drug research and development; (2) to conduct clinical trials to test whether drugs are safe and effective; (3) to decide what clinical trial data to disclose to the public; (4) to monitor post marketing drug safety; (5) to supply product information to physicians and to finance continuing medical education and other professional activities. The article suggests options to overcome each of these dependencies. © 2013 American Society of Law, Medicine & Ethics, Inc.

    Parkinson's disease (PD) is a progressive disease of the nervous system, and is currently managed through commercial tablets that do not sufficiently enable controlled, sustained release capabilities. It is hypothesized that a drug delivery system that provides controlled and sustained release of PD drugs would afford better management of PD. Hollow microcapsules composed of poly-l-lactide (PLLA) and poly (caprolactone) (PCL) are prepared through a modified double-emulsion technique. They are loaded with three PD drugs, i.e., levodopa (LD), carbidopa (CD), and entacapone (ENT), at a ratio of 4:1:8, similar to commercial PD tablets. LD and CD are localized in both the hollow cavity and PLLA/PCL shell, while ENT is localized in the PLLA/PCL shell. Release kinetics of hydrophobic ENT is observed to be relatively slow as compared to the other hydrophilic drugs. It is further hypothesized that encapsulating ENT into PCL as a surface coating onto these microcapsules can aid in accelerating its release. Now, these spray-coated hollow microcapsules exhibit similar release kinetics, according to Higuchi's rate, for all three drugs. The results suggest that multiple drug encapsulation of LD, CD, and ENT in gastric floating microcapsules could be further developed for in vivo evaluation for the management of PD. © 2016 WILEY-VCH Verlag GmbH & Co.

  15. Drug law reform, performativity and the politics of childhood.

    Flacks, Simon Jonathan

    2018-01-01

    Children are critical to debates about drug law reform. For both advocates of liberalisation and, especially, defenders of prohibition, the protection of children is an important rhetorical device in pressing for, or resisting, change. However, the privileged position of minors within such discussions, or talk about drugs in general, has rarely been explored in any depth in either drug and alcohol studies or legal research. Drawing on scholarship on performativity, and particularly John Law's work on 'collateral realities', this article will consider how constructs such as childhood and drugs are 'produced' and '(re)made' in such discourses. Through analysis of legal measures, policy documents/statements submitted to the UN General Assembly Special Session on Drugs (UNGASS) in 2016, and scientific discussion, it will be argued that such 'realities' include the constitution of the child as the logical victim of drugs (and the natural beneficiary or casualty of reform), and the enactment of drugs as an inherent threat to children. It is suggested that drug policy research needs to pay attention to age as a social construct and cultural category, and that a critical awareness of the relevance of age in policy discourse is as necessary as, for example, race, class or gender. Moreover, attendance to the ontological politics of constructs such as 'childhood' and 'drugs' is important if law and policy measures are to account for young people's agency.

    Although the Internet of things (IoT) brought unlimited benefits, it also brought many security issues. The access control is one of the main elements to address these issues. It provides the access to system resources only to authorized users and ensures that they behave in an authorized manner during their access sessions. One of the significant components of any access control model is access policies. They are used to build the criteria to permit or deny any access request. Building an ef...

    Full Text Available Johan Karlsson, Saba Atefyekta, Martin Andersson Department of Chemical and Biological Engineering, Chalmers University of Technology, Gothenburg, Sweden Abstract: The osseointegration capacity of bone-anchoring implants can be improved by the use of drugs that are administrated by an inbuilt drug delivery system. However, to attain superior control of drug delivery and to have the ability to administer drugs of varying size, including proteins, further material development of drug carriers is needed. Mesoporous materials have shown great potential in drug delivery applications to provide and maintain a drug concentration within the therapeutic window for the desired period of time. Moreover, drug delivery from coatings consisting of mesoporous titania has shown to be promising to improve healing of bone-anchoring implants. Here we report on how the delivery of an osteoporosis drug, alendronate, can be controlled by altering pore size and surface energy of mesoporous titania thin films. The pore size was varied from 3.4 nm to 7.2 nm by the use of different structure-directing templates and addition of a swelling agent. The surface energy was also altered by grafting dimethylsilane to the pore walls. The drug uptake and release profiles were monitored in situ using quartz crystal microbalance with dissipation (QCM-D and it was shown that both pore size and surface energy had a profound effect on both the adsorption and release kinetics of alendronate. The QCM-D data provided evidence that the drug delivery from mesoporous titania films is controlled by a binding–diffusion mechanism. The yielded knowledge of release kinetics is crucial in order to improve the in vivo tissue response associated to therapeutic treatments. Keywords: mesoporous titania, controlled drug delivery, release kinetics, alendronate, QCM-D

    With an increase in prescription drug spending and rising drug costs there is a need to encourage the use of generic prescription drugs. However, maximizing generic drug use is not possible without the public's positive perception and meeting their informational needs about generic drugs. Thus, improving the public's confidence in, and knowledge of generic drugs on the market is critical. The objective of this systematic review is to examine and evaluate the studies focusing on the nature and extent of key factors influencing generic drug use in the United States in order to help guide policy, education and practice interventions. Using multiple search engines and key word screening criteria, empirical studies published in English between January 1, 2005 and December 31, 2015 were identified. A qualitative synthesis of the evidence identified domains of key factors that influenced generic drug use across studies. Over 3000 citations met the key word screening criteria; 67 of these met inclusion criteria for the systematic review. Seven domains of factors that influence generic drug utilization were identified: 1) patient-related factors, 2) formulary management or cost containment, 3) healthcare policies, 4) promotional activities, 5) educational initiatives, 6) technology, and 7) physician-related factors. Patients, physicians, pharmacists, formulary managers, and policymakers play an important role in generic drug use. Understanding the factors influencing generic drug use can help guide future policy, education, and practice interventions to increase generic drug use. Copyright © 2017 Elsevier Inc.

    To assess the influence of infertility and fertility drugs on risk of ovarian tumors. Case-control study (Mayo Clinic Ovarian Cancer Study). Ongoing academic study of ovarian cancer. A total of 1,900 women (1,028 with ovarian tumors and 872 controls, frequency matched on age and region of residence) who had provided complete information in a self-report questionnaire about history of infertility and fertility drug use. None. Effect of infertility history, use of fertility drugs and oral contraception, and gravidity on the risk of ovarian tumor development, after controlling for potential confounders. Among women who had a history of infertility, use of fertility drugs was reported by 44 (24%) of 182 controls and 38 (17%) of 226 cases. Infertile women who used fertility drugs were not at increased risk of developing ovarian tumors compared with infertile women who did not use fertility drugs; the adjusted odds ratio was 0.64 (95% CI, 0.37, 1.11). The findings were similar when stratified by gravidity and when analyzed separately for borderline versus invasive tumors. We found no statistically significant association between fertility drug use and risk of ovarian tumors. Further larger, prospective studies are needed to confirm this observation.

    In this case study from Nicaragua, an account is given of how the Essential Drugs Program developed in a context which relectss exceptional political, economic and military pressures. The overall picture could provide a useful guide to the issues behind such an apparently simple concept as the essential drugs list. The criteria for including drugs in the National Formulary were those of the WHO report on essential drugs: proven efficacy, acceptable risks associated with their use, favorable cost, and need. A proposal of the basic list of drugs, classified in therapeutic groups and according to their priority and level of use, was prepared by a central Committee for the National Drug Formulary. An annotated Formulary was prepared to ensure consistency with rigorous scientific standards and to meet the needs of daily practice. The annotated therapeutic formulary has been distributed to all physicians, other health workers responsible for peripheral health centers, pharmacists, and medical students. It has been adopted as the main reference textbook for teaching clinical pharmacology and therapeutics to medical students. A training program in clinical pharmacology has been started at the University Autonoma de Barcelona. It pays particular attention to drug evaluation, drug epidemiology methods, and retrieval and preparation of drug information for health workers.

    2011-06-01

    Full Text Available Using a sample of 1486 Chinese A-share listed companies for the period 2004–2008, this study empirically tests the impact of family control, institutional environment and their interaction on the cash dividend policy of listed companies. Our results indicate that (1 family firms have a lower cash dividend payout ratio and propensity to pay dividends than non-family firms; (2 a favorable regional institutional environment has a significant positive impact on the cash dividend payout ratio and propensity to pay dividends of listed companies; and (3 the impact of the regional institutional environment on cash dividends is stronger in family firms than in non-family firms. Somewhat surprisingly, we find that controlling family shareholders in China may intensify Agency Problem I (the owner–manager conflict rather than Agency Problem II (the controlling shareholder–minority shareholder conflict, and thus have a significant negative impact on cash dividend policy. In contrast, a favorable regional institutional environment plays a positive corporate governance role in mitigating Agency Problem I and encouraging family firms to pay cash dividends.

  4. Effects of tobacco control policies on smoking prevalence and tobacco-attributable deaths in Mexico: the SimSmoke model

    Directory of Open Access Journals (Sweden)

    Luz Myriam Reynales-Shigematsu

    Full Text Available OBJECTIVE: To examine how policies adopted in Mexico in response to the Framework Convention on Tobacco Control affected smoking prevalence and smoking-attributable deaths. METHODS: The SimSmoke simulation model of tobacco control policy is applied to Mexico. This discrete time, first-order Markov model uses data on population size, smoking rates and tobacco control policy for Mexico. It assesses, individually and jointly, the effects of seven types of policies: cigarette taxes, smoke-free air laws, mass media campaigns, advertising bans, warning labels, cessation treatment, and youth tobacco access policies. RESULTS: The Mexico SimSmoke model estimates that smoking rates have been reduced by about 30% as a result of policies implemented since 2002, and that the number of smoking-attributable deaths will have been reduced by about 826 000 by 2053. Increases in cigarette prices are responsible for over 60% of the reductions, but health warnings, smoke-free air laws, marketing restrictions and cessation treatments also play important roles. CONCLUSIONS: Mexico has shown steady progress towards reducing smoking prevalence in a short period of time, as have other Latin American countries, such as Brazil, Panama and Uruguay. Tobacco control policies play an important role in continued efforts to reduce tobacco use and associated deaths in Mexico.

Mesoporous silica nanoparticles as promising drug nanocarriers have become a new area of interest in recent years due to their unique properties and capabilities to efficiently entrap cargo molecules. This review describes the latest advances on the application of mesoporous silica nanoparticles in drug delivery. In particular, we focus on the stimuli-responsive controlled release systems that are able to respond to intracellular environmental changes, such as pH, ATP, GSH, enzyme, glucose, and H2O2. Moreover, drug delivery induced by exogenous stimuli including temperature, light, magnetic field, ultrasound, and electricity is also summarized. These advanced technologies demonstrate current challenges, and provide a bright future for precision diagnosis and treatment.

  6. Access Control with Delegated Authorization Policy Evaluation for Data-Driven Microservice Workflows

    Directory of Open Access Journals (Sweden)

    Davy Preuveneers

    2017-09-01

    Full Text Available Microservices offer a compelling competitive advantage for building data flow systems as a choreography of self-contained data endpoints that each implement a specific data processing functionality. Such a ‘single responsibility principle’ design makes them well suited for constructing scalable and flexible data integration and real-time data flow applications. In this paper, we investigate microservice based data processing workflows from a security point of view, i.e., (1 how to constrain data processing workflows with respect to dynamic authorization policies granting or denying access to certain microservice results depending on the flow of the data; (2 how to let multiple microservices contribute to a collective data-driven authorization decision and (3 how to put adequate measures in place such that the data within each individual microservice is protected against illegitimate access from unauthorized users or other microservices. Due to this multifold objective, enforcing access control on the data endpoints to prevent information leakage or preserve one’s privacy becomes far more challenging, as authorization policies can have dependencies and decision outcomes cross-cutting data in multiple microservices. To address this challenge, we present and evaluate a workflow-oriented authorization framework that enforces authorization policies in a decentralized manner and where the delegated policy evaluation leverages feature toggles that are managed at runtime by software circuit breakers to secure the distributed data processing workflows. The benefit of our solution is that, on the one hand, authorization policies restrict access to the data endpoints of the microservices, and on the other hand, microservices can safely rely on other data endpoints to collectively evaluate cross-cutting access control decisions without having to rely on a shared storage backend holding all the necessary information for the policy evaluation.

    In this study, plasma polymerization of acrylic acid was employed to immobilize drug and control its release. Doxorubicin (DOX) was immobilized covalently on the glass surface deposited with plasma polymerized acrylic acid (PPAAc) thin film containing the carboxylic group. At first, the PPAAc thin film was coated on a glass surface at a pressure of 1.33 Pa and radio frequency (RF) discharge power of 20 W for 10 min. DOX was immobilized on the PPAAc deposition in a two environment of phosphate buffer saline (PBS) and dimethyl sulfoxide (DMSO) solutions. The DOX immobilized surface was characterized by scanning electron microscope, atomic force microscope and attenuated total reflection Fourier transform infrared spectroscopy. The DOX molecules were more immobilized in PBS than DMSO solution. The different immobilization and release profiles of DOX result from the solubility of hydrophobic DOX in aqueous and organic solutions. Second, in order to control the release of the drug, PPAAc thin film was covered over DOX dispersed layer. Different thicknesses and cross-linked PPAAc thin films by adjusting deposition time and RF discharge power were covered on the DOX layer dispersed. PPAAc thin film coated DOX layer reduced the release rate of DOX. The thickness control of plasma deposition allows controlling the release rate of drug. - Highlights: • Doxorubicin was immobilized on the surface of plasma polymerized acrylic acid thin film. • Release profile of doxorubicin was affected by aqueous and organic solutions. • Plasma polymerized acrylic acid thin film can be used to achieve controlled release.

    1990-11-03

    Violent deaths are of considerable importance among young adults, since they account for half the deaths in this age group (average age 26.4 years). Suicide and accidents (both categories including drug overdoses) are the most frequent categories of deaths from non-natural causes, while in the USA deaths by homicide are also of considerable importance. Current repressive policies have not brought the problem of drug addiction under control. Each year deaths by overdose among drug abusers occur. Nevertheless, 40% of deaths among drug addicts are from other causes, principally accidents and suicides. In the near future, AIDS may well account for the majority of deaths among drug addicts, thus adding to the mortality from overdose, both accidental and suicidal. Has the time come to reconsider the problem of drug abuse and to find radical solutions which would previously have been unthinkable?

    Water pipe tobacco smoking (WTS) is growing in popularity among U.S. young adults and is associated with health risks similar to those of cigarette smoking. The purpose of this study is to examine existing tobacco control policies (TCPs) in order to investigate how they engage WTS. A systematic synthesis of content and legal interactions among federal, state, and local TCP documents. Pennsylvania, which represents a politically and demographically diverse microcosm of the United States. No human subjects. Federal and state TCPs were retrieved via public legal repositories. Local policy searches were conducted via county/municipal Web sites, inclusive of 13 localities that had autonomous health departments or existing TCPs based on a National Cancer Institute report. Full-text TCPs were double coded within a grounded theory framework for health policy analysis. Emergent codes were used to compare and contrast policy texts and to examine legal interactions among TCPs. Examination of policy categories including youth access, use restrictions, and taxation revealed WTS as largely omitted from current TCPs. WTS was sometimes addressed as an "other" tobacco product under older TCPs, though ambiguities in language led to questionable enforceability. State preemptions have rolled back or prevented well-tailored reforms at the local level. Federal preemptions have likewise constrained state TCPs. Outdated, preempted, and unclear policies limit the extent to which TCPs engage WTS. Health advocates might target these aspects of TCP reform.

    2003-01-01

    Using the MARKAL simulation tool, different economic incentives in climate mitigation policy such as tradable emission permits, green certificates and carbon dioxide taxes have been analyzed. The analysis shows that there is an important advantage in applying the emission reductions internationally compared to a national policy, due to the varying marginal costs for the measures in different countries. The analysis also reveals at which price levels the Nordic countries as a whole become net sellers or net buyers of emission permits. The effects of combining emission permits with green certificates are analyzed, e.g. the inverse relation between permit and certificate prices. An appendix to the report gives a description of the Swedish energy system, emissions world-wide and examples of cost-effective mitigation measures for Sweden

    Specialised services should be developed to help people with schizophrenia and associated substance misuse. The extent of the problem therefore needs to be known. To determine the use of drugs, alcohol and tobacco by people with schizophrenia drawn from rural, suburban and urban settings, and to compare use by general population control subjects. People with schizophrenia (n=316) and general population controls of similar gender distribution, age and postcode area of residence (n=250) were identified in rural, urban and suburban areas of Scotland. Use of drugs and alcohol was assessed by the Schedules for Clinical Assessment in Neuropsychiatry, and use of tobacco by a questionnaire. More patients than controls reported problem use of drugs in the past year (22 (7%) v. 5 (2%)) and at some time before then (50 (20%) v. 15 (6%)) and problem use of alcohol in the past year (42 (17%) v. 25 (10%)) but not at some time previously (99 (40%) v. 84 (34%)). More patients were current smokers (162 (65%) v. 99 (40%)). Problem use of drugs and alcohol by people with schizophrenia is greater than in the general population, but absolute numbers are small. Tobacco use is the greatest problem.

    Full Text Available Generic medicines play a key role in managing the financial resources for pharmaceuticals in every country. This study analysed the generic policy legislative framework in Bulgaria with the aim to identify whether the policy implementation can be considered successful in the light of an international review of such policies introduced in other countries, or on the contrary, it has failed to deliver the main benefits. Legislative analysis, desktop study and macroeconomic overview of the Bulgarian pharmaceutical market were included. The study showed that only 3 out of 11 important policy elements are implemented in the country. Bulgaria has one of the highest shares of generics, an average of 81.39% (volume, for the studied period (2006–2014. However, further research is needed to evaluate the success of the existing generic policy in Bulgaria, as the market share of generic drugs is not the only measure of the policy efficiency.

    In this study we investigated the possibility of using layer-by-layer deposition, based in natural polymers (chitosan and alginate), to control the release of different ophthalmic drugs from three types of lens materials: a silicone-based hydrogel recently proposed by our group as drug releasing soft contact lens (SCL) material and two commercially available materials: CI26Y for intraocular lens (IOLs) and Definitive 50 for SCLs. The optimised coating, consisting in one double layer of (alginate - CaCl2)/(chitosan+glyoxal) topped with a final alginate-CaCl2 layer to avoid chitosan degradation by tear fluid proteins, proved to have excellent features to control the release of the anti-inflammatory, diclofenac, while keeping or improving the physical properties of the lenses. The coating leads to a controlled release of diclofenac from SCL and IOL materials for, at least, one week. Due to its high hydrophilicity (water contact angle≈0) and biocompatibility, it should avoid the use of further surface treatments to enhance the useŕs comfort. However, the barrier effect of this coating is specific for diclofenac, giving evidence to the need of optimizing the chemical composition of the layers in view of the desired drug.

    Iron oxide nanoparticles can serve as a heating source upon alternative magnetic field (AMF) exposure. Iron oxide nanoparticles can be mixed with thermosensitive nanovehicles for hyperthermia-induced drug release, yet such a design and mechanism may not be suitable for controllable drug release applications in which the tissues are susceptible to environmental temperature change such as brain tissue. In the present study, iron oxide nanoparticles were entrapped inside of thermosensitive liposomes for AMF-induced drug release while the environmental temperature was maintained at a constant level. Carboxyfluorescein was co-entrapped with the iron oxide nanoparticles in the liposomes as a model compound for monitoring drug release and environmental temperature was maintained with a water circulator jacket. These experiments have been successfully performed in solution, in phantom and in anesthetized animals. Furthermore, the thermosensitive liposomes were administered into rat forearm skeletal muscle, and the release of carboxylfluorescein triggered by the external alternative magnetic field was monitored by an implanted microdialysis perfusion probe with an on-line laser-induced fluorescence detector. In the future such a device could be applied to simultaneous magnetic resonance imaging and non-invasive drug release in temperature-sensitive applications.

    The present investigation concerns the development and evaluation of a novel drug delivery system, aminated-glycidylmethacrylate grafted cellulose-grafted polymethacrylic acid-succinyl cyclodextrin (Cell-g-(GMA/en)-PMA-SCD) for the controlled release of 5-Fluorouracil, an anticancer drug. The prepared drug carrier was characterized by FT-IR, XRD and SEM techniques. Binding kinetics and isotherm studies of 5-FU onto Cell-g-(GMA/en)-PMA-SCD were found to follow pseudo-second-order and Langmuir model respectively. Maximum binding capacity of drug carrier was found to be 149.09 mg g-1 at 37 °C. Swelling studies, in vitro release kinetics, drug loading efficiency and encapsulation efficiency of Cell-g-(GMA/en)-PMA-SCD were studied. The release kinetics was analyzed using Ritger-Peppas equation at pH 7.4. Cytotoxicity analysis on MCF-7 (human breast carcinoma) cells indicated that the drug carrier shows sustained and controlled release of drug to the target site. Hence, it is evident from this investigation that Cell-g-(GMA/en)-PMA-SCD could be a promising carrier for 5-FU.

    In an effort to mitigate Kentucky's prescription drug misuse, legislative intervention efforts were introduced in 2012 and 2013 to better regulate pain clinics, prescribed use of opioid analgesics, and to expand the monitoring of opioid prescriptions. The focus of this paper is primarily on opioid analgesics and heroin and the relationship of use/misuse patterns of these drugs to state drug policy initiatives. A secondary data analysis of drug treatment clients (N=52,360) was conducted to project illicit drug use trends in Kentucky. This study describes temporal and geographic trends of self-reported illicit drug use among individuals in state-funded treatment in Kentucky between fiscal year 2010 and fiscal year 2013. Significant reductions in the prevalence of illicit opioid use, declined from fiscal year 2010 to fiscal year 2013 (p<.01, CI=-.298 to -.215). However, heroin use rates significantly increased over the years studied, suggesting there may be a transition from prescription opioids to heroin (p<.01, CI=.143 to .178). The analysis suggests these trends may continue. Findings suggest Kentucky's legislative efforts were effective in reducing illicit prescription opioid use, but heroin use has increased. One possible explanation for this relationship is that as prescription opioids became more difficult to obtain, users turned to heroin as a substitute. The finding of rising heroin use suggests a need for further policy initiatives to reduce heroin use, but the potential effectiveness of this policy remains unclear. Understanding trends may help to guide future policy efforts and pain management treatment strategies to where they might have their greatest impact. Copyright © 2017 Elsevier B.V.
